Abstract

The present invention enables improved and more efficient recharging of electric cars, preferably by using improved batteries and/or improved recharger arrangements in electric cars and/or in infrastructures that are used for recharging electric cars, and/or other improvements in the infrastructures, while preferably also protecting the electric grid from overload. This is preferably done for example by accumulating energy in service stations for example in special preferably hi gh speed capacitors, such as for example one or more super capacitors, and/or for example one or more molten salt accumulators and/or for example in the new M1 batteries developed by A123 Systems or similar batteries or other fast batteries which can be recharged for example to 80% capacity within 5 minutes, or for example the similar fast new batteries by Toshiba or for example the BYD Iron Phosphate batterie s or for example the Altair Nanotechnologies Nanosafe battery, so that preferably these accumulators can be used for example to recharge cars with M1 batteries or similar fast-recharge batteries, since otherwise the service station would need to have a huge capacity power supply to enable such fast recharges. Other covered variations include for example efficient methods of recharging the batteriespreferably serially, either in the service station (based on a model of fast replacement of batteries at the service station), preferably after automatically sorting the batteries into more or less homogenous groups, or in the car itself for example by automatically rerouti ng the batteries or some of them or elements in them during recharge so that they a re recharged more serially than during the normal operation of the car, thus enabling recharge with less rechargers and/or at higher voltages and with less curren t and less problems of heat during recharge. Other described improvements include for example a system wherein when recharging the electric cars, for example rechargers and/or for example one or more central computers for example in the electric al grid company and/or in the service provider take into account also car-specific parameters in order to optimize the recharging priorities, for example based on the state of their batteries and/or for example also based on additional parameters and/or heuristics and/or statistics and/or for example automatic repeated identification of cars based for example on a unique preferably digital ID number, so that for example the system can take into account also various regular and/or historical car- specific parameters and/or patterns and/orstatistics, such as for example typical arrival and departure times, typical distances traveled, specific needs base d on week days, etc. Other features include for example a system and method for alerti ng users when a parking and/or recharging post becomes available and/or reserving the m in advance. Other features include for example various improvements in the electric cars themselves.

Description

24/12/08 Yaron Mayer & Haim Gadassi 3/304 Backeround of the invention Field of the invention The present invention relates to improved electric cars and/or improved infrastructures for recharging electric cars, and more specifically to improved and more efficient recharging of electric cars, preferably by using improved batteries and/or improved recharger arrangements in electric cars and/or in infrastructures that are used for recharging electric cars and/or other improvements in the infrastructures.

Background The outrageous costs of fuel, which have recently reached around $140 per barrel and have since fallen back considerably but are expected to eventually rise again as we are reaching peak oil or are at least unreliable, and the cumulative environmental and health costs of air pollution, are driving more and more serious search for alternatives to gasoline. One of the most promising alternatives is electric cars, however such cars still have various problems that delay their penetration in the markets, such as for example the need for efficient infrastructure for recharging and servicing such cars in service stations and the need for appropriate arrangements that enable users to recharge their cars for example at home or for example in public rechargers or recharge posts in the street in an efficient way. The present invention focuses among other things on solving efficiently the recharge problems of electric cars.

Summary of the invention The present invention enables improved and more efficient recharging of electric cars, preferably by using improved batteries and/or improved recharger arrangements in electric cars and/or in infrastructures that are used for recharging electric cars, and/or other improvements in the infrastructures, while preferably also protecting the electric grid from overload.

Preferably in electric cars the car can be quickly recharged in service stations (the equivalent of gas stations in normal cars) preferably by designing the batteries in a modular fashion so that preferably one or more of the batteries can be preferably instantly removed from the car and replaced with charged batteries, and preferably the batteries in the car are configured so that they can automatically recharge each other or spread the power among them, so that for example if 12 batteries were replaced and 6 not then the 12 charged batteries can automatically share their charge with the other batteries that have not been replaced. (In the variations where modular elements can be replaced one by one this also means that preferably for example the user can remove for example separately each individual element manually without need for special equipment, thus for example also being able to recharge for example at home spare batteries or elements. But still preferably the user needs for example a smart card and/or password to be able to excess the 24/12/08 Yaron Mayer & Haim Gadassi 4/304 batteries, as explained elsewhere in this application). The replaced batteries are then preferably recharged automatically at the service station (which means of course that the station can spread the recharging time as convenient for example over hours and/or for example mainly during cheaper night hours), and preferably the service is based on some monthly subscription and/or some other identification of the customers, so that for example the user is extra-charged if his/her batteries are faulty, and/or for example the service includes also an extra charge for insuring the batteries. Another possible variation is that, since not everyone has a private garage when he/she can set-up an outlet for recharging an electric car, preferably for example the municipal authorities are responsible for creating preferably for example near street light poles and/or near power line poles also electric car recharging outlets, so that preferably the same electric wiring that already exists for the power line poles or the street light poles can be used also for the car recharging outlet preferably without having to add wires, and preferably the users pay for this by a credit card or smart card which is preferably read automatically by the outlet.
Another possible variation is to use for example in service stations for example one or more cooled super conductor for example in a ring shape or other structure and/or for example one or more super cap capacitors as accumulators, and/or for example one or more molten salt accumulators (such as for example the new molten salt -sodium with metal chlorine accumulator battery which GE developed for their new evolution hybrid locomotors, in which 20 such batteries can generate 2000 horse powers within a second) so that the service station can accumulate the energy more freely for example 24 hours a day or for example (preferably automatically) mainly in the cheaper night hours, so that preferably the service station can this way even charge fast car batteries without the need to swap batteries, for example in cars which with new Ml batteries developed by A123 Systems or similar batteries which can be recharged for example to 80% capacity within 5 minutes or other fast recharge devices such as for example one or more super capacitors such as for example EEStor, which can also be recharged in a few minutes, since otherwise the service station would need to have a huge capacity power supply to enable such fast recharges. Another possible variation is that the service station uses for example a preferably large number of local Ml batteries or similar batteries or other fast charge batteries or super capacitors such as for example EEStor to recharge through these batteries or super capacitors the car batteries in cars that come for recharge -thus similarly preferably being able to charge such cars in real time without the need to replace the batteries (since typically batteries that can be recharged so fast can also be discharged very fast for recharging cars that come to the station), so that preferably the station uses its local fast batteries as accumulators, recharging them for example 24 hours or for example mainly for example in the cheaper night hours.
Another possible variation is for example to create a preferably small electrical power station in at least some of the service stations, for example based on burning gas. Another possible variation is that preferably in order to enable faster recharge time of the cars, especially if for example the cars use Ml or similar fast charging batteries (such as for example the new fast charge batteries for example by Toshiba or by LG) or other fast recharge devices such as for example one or more super capacitors such as for example EEStor (EEstor for example is expected to be considerably cheaper then Ml batteries and offer a 3-4 times larger range, eventhough Ml is already cheaper and much better then normal lithium-ion 24/12/08 Yaron Mayer & Haim Gadassi 5/304 batteries), so that preferably a car can be recharged at the service station for example on the fly preferably in a few minutes, and preferably in order to solve problems such a huge current would create (such as needed very thick wires, and reducing huge amounts of heat from even 1% lost energy during the transfer), preferably the recharging can preferably be done at much higher voltages than the normal operating voltage of the electric car batteries. This is preferably done by electrical and/or mechanical switches and/or multiplexers in the car and/or in the array of the for example batteries used by the service station to charge the car, so that preferably during recharge, the batteries (preferably both the car batteries that are being recharged and the for example batteries that are recharging them) are preferably automatically preferably reconnected serially instead of in parallel, so that for example if there are 20 50-volt batteries or battery modules in the car, preferably during recharge at the service station or for example at home these batteries and/or elements (for example internal cells) in them and/or at least some of them are preferably connected serially, so that they can be recharged at preferably for example 1000 volts or even more (or other convenient high voltagesj, which means much less current, less need for ultra thick wires even at high speed recharges (preferably both in the car and in the extemal recharging interface), and much less problems of heat from the typical 1% loss of energy during the recharge.
Similarly, preferably while the station is recharging their batteries outside of cars (for example their own batteries and/or accumulators and/or superconductors that are preferably charged for example mainly at night hours to be used for later recharging car batteries during the day) and/or while recharging car batteries which are replaced for the recharge, preferably this recharging at the night time is preferably also done in serial batches of preferably a least 1000 volts (or other convenient high voltages), for similar reasons (preferably by connecting serially batteries of multiple cars for recharging together at the same time). Similarly, if for example cars with Ml batteries or for example the similar fast new batteries by Toshiba or for example the BYD Iron Phosphate batteries or for example the Altair Nanotechnologies Nanosafe battery or similar fast recharge batteries or other batteries or other fast recharge devices such as for example one or more super capacitors such as for example EEStor are recharged also for example at the homes, preferably mainly during the night hours (and/or for example in offices where the car is typically parked during the working hours), preferably the same or similar electrical and/or mechanical switching and/or multiplexing mechanism can be used for example for creating preferably the most optimal voltage conditions for the relevant power supply, so that for example in areas like Israel where there is a power supply of 220 volts in normal connections and around 400 volts if a 3-phase connection is available, preferably the batteries can be for example preferably automatically switched in a position of for example part parallel and part serial (for example some batteries are connected in parallel in some serially and/or for example other concurrent types of combinations are used) and/or connected serially with a proper voltage adjustment and/or other electronic compensation and/or conversion (preferably the rerouting to serial or part serial connections enables using the available voltage without a need for transformers, which would increase wastes and make the recharger more expensive), so that preferably they can be recharged most efficiently at the home for example with for example 220 volts in 1-phase systems or for example around volts in 3-phase systems, and for example in the US where the typical electric outlet 24/12/08 Yaron Mayer & Haim Gadassi 6/304 voltage is half of that, preferably the batteries can be again preferably rewired accordingly during the recharge, preferably automatically, and similarly if the recharging in the service station can be done for example with 1000 Volts or more, then the serial routing is changed accordingly for that, preferably automatically, as explained above. This rewiring is preferably done through computerized control so that preferably the user can enter for example on an LCD console for example the available voltage value and/or the duration of time available or desired for the recharge and/or for example the maximum amperage desired or available during the recharge, and/or for example more preferably the recharger senses the available voltage automatically, which is also safer in case the user might give the wrong voltage parameter by mistake (for example by analogue means and/or by digital communication with the recharger), and then preferably the computer that runs this in the car recharger preferably first moves the switches and/or multiplexers and/or other electrical controls to the appropriate configuration and preferably only then makes the connection and/or allows the recharging current to start flowing, and preferably controls the rate of the recharge for example through PWM or other known means. If for example the car contains only a single large and/or powerful battery (or for example only few more powerful batteries than the typical preferably about 20 batteries, such as for example 5 or less), then preferably the battery itself (which would typically contain multiple cells of smaller voltage internally) preferably contains appropriate mechanical and/or electrical switches and/or multiplexers (and/or for example chemical means) internally in order to enable this switching internally so that preferably internal elements within the battery can be switched to become connected more serially during the recharge of the car batteries, and if multiple batteries are used then preferably these mechanical and/or electrical switches and/or multiplexers are included in the housing of the batteries in the car (which can be for example part of the car or for example a modular part or frame which contains the batteries, so that for example this modular part contains the actual batteries and can be inserted into the car like a larger battery, so that the car itself does not have to be changed for this). As explained above, the appropriate serial rerouting for recharging and/or the rerouting back to for example parallel or partly parallel connections after the recharging are preferably done automatically for example after the recharge connector unit senses the voltage (for example 3 phase or normal, as explained above), and preferably the car computer or the recharger's processor automatically preferably issues the command for rerouting accordingly before allowing the circuit to close and the recharge to begin. So for example if the electric car has 2 or 3 sets of battery stacks in which for example during normal operation each stack is composed of a number of serially connected batteries or cells which produce for example 250 or 300 or 350 volts, so that for example these stacks work together in parallel with each other in order to boost the current (or for example one or more stacks are activated only when the car is accelerating), so when recharging the stacks serialiy if there are for example 2 stacks then the recharging voltage can be for example 600 or 700 volt and if there are for example 3 stacks then the recharging of all the 3 stacks can be done for example at 900 or 1050 volt (which can be done for example at the service station or preferably for example also at special street recharges), and for example if recharged at home the stacks in this example can remain parallel. This has also an additional advantage since this means that preferably while recharging the system has automatic additional 24/12/08 Yaron Mayer & Haim Gadassi 7/304 safeguards against the user getting electrified, since until the connection is complete preferably only low current and preferably also only low voltage is used for the preferably digital communication (i.e. preferably a current and/or voltage that are safe even if humans are exposed them directly, such as for example 12 volts or below and/or for example a current below a few milliamperes or other low voltage and/or low current which is considered non-dangerous even if humans are exposed them directly). In addition, preferably there is for example a mechanical and/or electrical sensor which preferably does not enable high voltages and/or high currents to go through before the recharge connector is fully and properly plugged in its position. Another possible variation is that for example preferably immediately after connecting the cable and/or for example before allowing the actual recharging to begin (for example the first time after connecting and/or for example also when automatically resuming recharging for example after a temporary stop) preferably the recharge post and/or for example the car's recharger preferably automatically test the function and/or safety of the cable and/or for example that the cable and/or its interface for example in the car and/or for example the plug has not been damaged, for example by sending first only a low current and/or low voltage but more preferably a high voltage with preferably extremely low or very low current, such as for example the recharge voltage of for example 380 volt or for example even 1000 volt but with a current of only a few microamperes (so that for examples power breaches can be more easily detected) and preferably checking for example if there is leaking to the grounding (preferably for example the car's chassis is preferably always connected to the grounding of the cable) and/or preferably also for example checking preferably before that if the grounding wire is properly connected (for example by a switch and/or microcontroller on the car and/or on the recharge-post that reroute the connection to go back through the grounding and checking if it is received back properly) and/or for example similarly if the other wires are properly connected, and/or for example checking if there is an internal short circuit in the cable (for example by sending low current with low voltage or a high voltage with for example a few microamperes as explained above and for example letting the car computer or the car's recharger report back for example how much current it received, and/or for example measuring automatically for example if sending a current for example on two wires creates a current on another wire or for example). These reroutings for testing can preferably be done for example by automatic switches on the power wires and/or the grounding wire and/or for example by one or more rotating elements that can change the connections by rotation so that for example when it returns to the normal position all the relevant connections are back to normal, or for example the testing circuits are insulated from the actual wires and are for example based on induction, so that the testing does not risk changing the actual connections (which means that for example the test currents and/or their sensing is preferably based on induction and preferably at least in the areas where the induction is applied or sensed preferably the power wires and/or grounding wire are preferably properly separated so that the induction does not effect directly the other wires or is not affected directly by them).
Another possible variation is that during these tests for example the wires are automatically disconnected from the recharger and connected instead for example to a current flow meter. Preferably the entire test sequence for the grounding and/or the other wires can be completed for example within a few seconds or for example less than a 24/12/08 Yaron Mayer & Haim Gadassi 8/304 minute or for example less than a second altogether. These variations mean of course that preferably the recharge post has a controller and/or switch that can control the amount of current and/or voltage that can go through or disable it, preferably even if it does not have a recharger circuitry, i.e. for example through a remote and/or locally controlled electrical and/or mechanical switch and/or for example a switch which is automatically opened for example only after receiving a command for example from the recharger and/or for example from the main computers of the service provider and/or of the electric company for example after the plug has been properly connected and preferably for example the car's Id/or user's Id have been properly verified and preferably after the cable has been automatically tested with low current and/or low voltage as explained above, and/or for example if a problem is detected preferably the car's computer updates the user and/or for example the service provider's main computer about the nature of the problem preferably with recommendation to the user what to do and preferably if the problem is severe enough for example the recharge is aborted and the user is for example requested to enter a service station or for example to use temporarily the other cable (for example if the car has at least to recharge cable for example one at the front and one at the back as explained elsewhere in this application, or for example if there is spare cable for example in the baggage which can be for example modularly connected instead of the faulty cable). Preferably the low current is created for example by a small power supply and/or transformer in the recharge post and/or for example by a small battery which is preferably used anyway in the recharge posts for example for receiving instructions even when the power is down, so that for example low current and low voltage can be taken from the battery and for example high voltage with for example a few microamperes is preferably taken from the power supply or transformer (or for example there is another power supply for the low volt low current, or for example the same power supply can generate both sets). Since after plugging-in the cable the user will typically remain already out of the car, preferably the car computer remains active also after the car is turned off and preferably also after the user exits the car, for example at least in standby mode, as explained also elsewhere in this application, and/or can for example tum itself off or into standby mode but can preferably be awakened automatically for example by events received for example through the cellular communication or for example generated by the recharger. So for example if a malfunction in the cable or for example in the plug or for example in the cable interface in the car is discovered or for example there is a problem for example with recharge permissions or authorization for example after the car's Id is automatically identified by the recharge post or after the car identifies the recharge post's Id, preferably this can be indicated to the user for example through synthesized speed or for example a set of pre-recorded available messages for example through the same external car speakers that are used during driving for example for engine sound simulation, or for example by the recharge post, for example through a small LCD monitor and/or for example through synthesized speech or prerecorded messages, or for example the user is directed back to the car for example through a short message or for example light indicator (for example on the recharge post) to receive a more detailed explanation and/or recommendations what to do for example at the cars computer's terminal. (If there is a problem for example with recharge permissions, preferably the service provider's main computer can automatically inform the user about his 24/12/08 Yaron Mayer & Haim Gadassi 9/304 for example through the car's computer direct cellular communication preferably even before reaching any recharge post for example if the problem is general, but if for example the problem is that the recharge post is limited for example to certain cars then the message can be displayed for example after connecting the cable, however in such case preferably there are proper warnings in advance for example that this recharge post is limited for example for only certain uses). These features or variations preferably work the same or similarly regardless of if the cable is connected from the car to the recharge post or from the recharge post to the car or for example between a socket on the car and a socket on the recharge post. As explained above and in other places in this application preferably the recharge post is designed so that until a car is properly plugged-in and authorized and/or until the user is authorized the only currents the recharge post allows to go through are safe low currents or safe low voltage low currents for testing and/or communication, or no currents at all, and preferably even the above described low currents are preferably activated only after a compatible plug has been properly connected and preferably after the data link has been properly connected - as explained also elsewhere in this application. For example in a recharge post with two sockets preferably the connection testing and/or short-circuit testing system is separate for each socket or for example the same system can be switched to test either of the sockets. Another possible variation is that the grounding connection is tested for example by using in the recharge cable for example two separate wires for the grounding instead of one, so that they are connected for example on the side of the car, and preferably the recharge post preferably constantly sends for example a low voltage low current through them and checks if it returns properly and preferably stops recharging immediately if it finds that the grounding has been disconnected and/or issues a preferably severe warning for example through the car's computer monitor (or for example this is done at short intervals such as for example very few seconds or other reasonable period, but the constant checking is more preferable and preferably also has very little effect on energy waste since it is preferably for example just a few milliamperes or less), which has the advantage that this way preferably the grounding can be automatically tested preferably all the time for example also during the recharge itself, thus reducing the risk of people who stand on the outside and touch the car getting electrified for example in case of a malfunction. In this case preferable the two grounding wires are preferably away from each other - for example at opposite sides of the cable, in order to reduce the chance of a short circuit between them, and/or for example they are also tested for short circuits between them (for example by disconnecting between them at the edge where they are normally connected and checking if current still flows between them) preferably during the preferably quick short circuits tests (and/or disconnections test) which are preferably automatically done for example when the cable is connected or before the actual recharging begins. (This is important because Eventhough the residual current fuse will jump anyway immediately or almost immediately for example in case of current starting to flow to the ground through a person standing next to the car even if there is a problem with the grounding, it can still be dangerous if the grounding is disconnected or does not function properly).
This means that for example if the cable is a 3 phase cable, i.e. typically has 4 wires plus a grounding (i.e. 5 wires with 5 pins in the plug), a cable which contains the additional grounding wire and for example two additional wires for balanced data 24/12/08 Yamn Mayer & Haim Gadassi 10/304 transfer will preferably have for example 8 wires and 8 pins (or for example the 2 grounding wire share the same pin by using for example a pin that is divided into two separate metal parts with an insulation between them). Another possible variation is that preferably the grounding wire (or wires) is preferably designed so that they are preferably the first to connect (preferably when inserting the plug) and the last to disconnect (preferably when removing the plug) - for example by making it or them with the longest pin in the plug.

Another possible variation is to use similar precautions even in systems without the serial rerouting during recharge. Another possible variation is to use for example internal mini or micro rechargers for example for individual elements within the battery so that each such mini recharger (preferably each with its own microprocessor) is preferably considerably cheaper than a normal recharger and preferably takes care more optimally of the relevant element or elements.

Another possible variation is that for example the electric car's engine itself is also designed to work at much higher voltages, such as for example around 1000 volts or other desired high voltages, so that for example the optimal recharge voltage and the working voltage can be the same or close, which also has the advantage that the engine can be made smaller and lighter, but on the other hand in that case better isolation and better precautions against voltage gap breaches are needed. Another problem is that in case of an accident with such high working voltages, or even with lower working voltages of for example 220 volts or 360 volts, especially if for example the battery compartment has been hit, there is a danger of sparks or voltage gap breaches causing a fire or of dangerous materials from the batteries flying around. So preferably this is improved so that for example the battery itself and/or stack of batteries and/or frame that contains the batteries and/or for example the car's container that contains the batteries is also isolated for example by wrapping or enveloping it for example with one or more preferably thin layers of highly tear resistant material, such as for example carbon fiber, or for example fiberglass fiber, such as for example the same material from which car air bags are made. Another possible variation is that preferably the system has for example accident sensors which can preferably in the case of a serious accident preferably instantly at least cut off the circuit of the high power batteries that power the engine. Preferably at least the car's computer and/or other systems, such as for example at least some of the display boards, are connected to at least one separate battery with lower voltage and current which is not affected by this, and preferably this small battery (which is preferably in the front like in normal cars) is preferably also a small fast recharge battery preferably of the same type as the main power batteries which are preferably at the back lower part of the car (preferably for example below the baggage chamber and/or for example below the back seat), such as for example Ml batteries, so that preferably the small front battery also has the same lifetime as the main power batteries (which for example in the case of Ml batteries is expected to last for about 10 years). (Another possible variation is that for example the main power battery or batteries are in the front of the car, for example near the engine and the small front battery, but that is less preferable since it can take up too much room in the front, and also it might make the car less stable in term of weight distribution). Another possible variation is that for example the 24/12/08 Yaron Mayer & Haim Gadassi 11/304 front small battery is placed instead for example at the back near the power batteries, but that is less preferable since keeping it at the front is what users expect in a normal car and offers more easy access, and also this way the chance that both batteries will be destroyed for example in case of an accident is significantly lower.
In addition, preferably the recharging of the small front battery is done directly from the main power batteries, for example through a power supply controller (for example as is done in a normal PC computer), and preferably this power supply includes for example a few branches of for example DC power cables, for example at the same voltage or at various different voltages, and preferably as many devices as possible (such as for example the car's headlights and/or other devices) are run for example at 48 volts instead of the normal 12 volts (since 48 volt is considered the maximum voltage which is considered low voltage) or other voltages above volts, or even at higher voltages with preferably additional safety &
isolation protection, which has the advantage that much thinner and lighter wires can be used, since for example in normal gasoline cars that have only a 12 volt battery the wires have to be quite thick and heavy to allow the high amperage that is needed for example for the headlights, and preferably for example only the main car computer and for example the radio and/or internal displays preferably work for example on lower voltages. In addition preferably the car's headlights preferably use for example mini-fluorescent light bulbs that preferably fit the same sockets used for normal light bulbs, for example similar to the type used in homes to replace normal light bulbs in the normal light bulb sockets (but preferably with shape and/or other parameters that are optimized for serving as headlights in cars), and/or for example more preferably for example similarly strong LED lights, and/or for example OLED, and/or for example other forms of light that produce light much more efficiently than normal light bulbs by wasting much less energy on heat (these are much more preferable than fluorescent light bulbs since for example in case fluorescent light-bulbs get smashed for example while working they can release mercury fumes), and/or for example if fluorescent lights are used they are preferably protected for example within special strong and hermetic-to-air for example transparent plastic cases which protect them and/or for example with sensors that automatically turn off the current when they are about to be smashed. However for example the headlights are preferably powered directly from the main power batteries, thus enabling an ever more compact and dedicated battery for the computer and other devices that typically require much less power, and/or for example preferably the power supply from the power batteries can power all the car's devices, and one of its cables is used for recharging the small front battery, and preferably the front battery serves mainly as a backup for the car's computer, internal display, and/or other emergency systems, so that for example only the car's computer and a few small energy other devices get their energy directly from the front small battery, or for example even they can get their energy both from the small front battery and from the power supply (for example if one of these is empty or malfunctioning). The power supply can be for example located at the back near the main power battery or batteries or for example located at the front near the engine, so that the main high voltage power lines from the power batteries go to the engine and near the engine there is a juncture that routes power both to the engine and to the power supply. Another possible variation is that preferably at least some of the power lines in the car use both a power line and a 0 or neutral line (for 24/12/08 Yaron Mayer & Haim Gadassi 12/304 example like in normal apartments, except that this is preferably DC), with the car body itself for example acting grounding, so that preferably this way the system can for - example automatically detect power leakage, thus preventing power waste and/or fire hazard.

Another possible variation is that preferably especially the locations of the transformers and/or inverters and/or the engine and/or the DC cable from the main power battery or batteries are preferably strongly shielded against electromagnetic and/or EMF and/or magnetic radiation (for example by proper metal casing, metal meshes, nickel -iron, and/or other types of magnetic and/or electromagnetic energy shields), so that preferably the driver and passengers and preferably also outsiders standing close to various parts of the car (for example while the car is being started for example after parking) are preferably properly shielded from levels of electromagnetic or magnetic radiation that are considered dangerous or might be dangerous or are for example beyond the typical levels for example in normal or equivalent gasoline cars, and preferably there are preferably in the car at least one or more preferably built-in sensors of electromagnetic and/or magnetic fields for example at the most problematic areas and/or at the areas most relevant to the passengers, such as for example near the passengers head level and/or at the center of the car, which preferably report directly to the car computer so that preferably the users can view preferably whenever they want the radiation levels for example on the car computer monitor and/or the computer can for example issue automatic warnings if the sensor or sensors indicate that there is a problem of radiation levels (for example after an accident), and/or for example at least authorized service garages are preferably required by law to run for example appropriate EMF
measurements in the car for example after accidents or certain types of accidents and/or for example after performing certain services that could affect the EMF
levels and/or for example as part of regular checkups or service. Another possible variation is that preferably for example in electric busses and/or trains and/or for example also in normal busses or trains, preferably in order to reduce the radiation that passengers are exposed to due to other people speaking by cellphone next to them and/or due to reflections of the radiation within the metal of the vehicle, preferably at least some busses and/or trains or example have and/or are required by law to have for example one or more pico-cells for example preferably at a certain height above the roof of the bus or for example at the back of the bus for example near the exhaust pipe of normal busses (but preferably at some distance of for example 1 meter or more to the right or to the left of it) - preferably as far as possible from the passengers' heads (and for example at least in a trains the pico-cell is preferably on an extension even further from the location of the passengers), so that preferably at least some or most or all of the cell phones in the buss will assume that the pico-cell is the nearest cell and will talk through it instead of through real cells which are typically much further away, and preferably these pico-cell or cells at the exterior of the bus or train are preferably for example limited to supporting for example only up to for example 20 or 30 phones at the same time or other reasonable number and/or are preferably limited in the amount of radiation that they are allowed to emit, so that preferably they cannot emit for example an amount of radiation of for example more that a normal cell phone can emit (for example up to 2 watts or a few watts) or for example more than N times a normal 24/12/08 Yaron Mayer & Haim Gadassi 13/304 phone, where N is for example 2 or 3 times more than a normal phone or other reasonable number. In addition, preferably at least in busses or trains which have such one or more pico-cells preferably there are at least one or more cellular radiation sensors preferably for example every few meters, which preferably for example start to beep or speak automatically (for example with prerecorded messages or synthesized speech) for example if the cellular radiation level for example exceeds a certain threshold. Another possible variation is that preferably at least some busses and/or trains preferable have at least one areas where talking with cell phones is allowed or not allowed and/or for example busses and/or trains are preferably required by law to have at least one area where talking with cellphones is not allowed for example like having smoking and non-smoking areas (so that preferably for example the non-smoking and no-cell-phone talking areas are the same area or for example separate areas with preferably some overlap), and preferably passengers in the no-cell-phone area can preferably for example fine people who talk on a cell phone next to them and refuse to stop immediately or for example within a few seconds when asked to. If one or more pico-cells are used for example in the bus or in the train preferably they have on the inside of the bus or the train for example on the inner side of the roof preferably one or more low power antennas which are preferably at least partially directional and/or sufficiently limited in range so that preferably they are mainly limited to the areas of the inside of the bus or train, so that for example in a crowded station preferably for example other phones used by people outside the bus don't use these pico-cells thus reducing the number of remaining channels which they can handle, and/or for example the number of pico-cells, and/or for example the number of channels which they can handle is preferably planned in advance to be sufficient. for example even if for example in a crowded station the pico-cells also communicate with a typical number of people who for example use cellular phones for example on the outside near the bus or train.

Similarly another problem is that for example many people are stupid or unaware enough to speak with cell phones inside metal elevators without realizing that in order to transmit from this Faraday cage the cell phone has to use maximum power and also every passenger who is unfortunate enough to be at the elevator at the same time is exposed to reflections of the energy again and again thus increasing the effect even much more until almost all of the microwave radiation is absorbed in their bodies, just like in a microwave oven, except for the lower wattage, which can still cause headaches and damage concentration and memory. So preferably this is improved do that cell phones preferably sense automatically (for example based on using their own antenna and their CPU to detect for example if their own pulse patterns are reflected back strongly almost instantly and/or for example based on sensing that the level of signals received from nearby cells suddenly drops sharply for example to levels close to or below a threshold that typically happens for example in elevators, which means that preferably simply a change in the firmware is needed for enabling these featuresj cases where they are within a small metal box such as for example an elevator (for example by sensing the reflections and/or the fact that the phone has to increase to maximum power and/or for example still has limited reception even at maximum power) (and/or for example sense similarly that they are encased for example in a closed for example thick concrete structure if for 24/12/08 Yaron Mayer & Haim Gadassi 14/304 example it has a similar effect as being encased in a metal box, and/or for example closed structures that have a similar effect - i.e. that are for example creating strong reflections back and force and blocking almost all the communication energy, thus for example forcing the phone to use maximum power) and preferably they automatically shut themselves down (i.e. for example disable any cellular communication attempts and preferably for example indicate that there is no reception for example on their monitor and/or for example that no cellular communication is allowed in an elevator or similar closed space and preferably indicate to the user clearly that no further communication attempts should be made for example until exiting the elevator, for example by a message on their screen and/or for example by synthesized speed or prerecorded message, and/or for example shut themselves down completely preferably after displaying the message) in such cases preferably immediately or as soon as they reach the conclusion that they are in such a place, and preferably they also similarly stop sending automatic probes or responses to cells that are trying to determine if they are still available in their area (otherwise even people who are merely carrying a closed cellular phone in an elevator and all the other passive vict'ims who are in the elevator at the same time are exposed to the radiation whenever such location probes signals are automatically sent by the cell phones, eventhough it is less than when taking on the phone), and preferably similarly they also sense this when receiving an incoming call and then preferably automatically only receive the message without ringing or for example automatically ignore it like being in non-reception zone (i.e. preferably the phone automatically senses that in is in an elevator or similar closed transmission-blocking structure for example also if it tries to connect with cells or senses an incoming transmission and preferably avoids these activities even if the user has not tried to talk on the phone in the elevator). Preferably the phone remains in this state (of preferably not allowing the user any cellular communication and preferably also stopping to attempt to connect to cells or to answer their attempt to contact the phone, as explained above) -' for example for a pre-set time (such as for example 1 or 2 or 3 minutes or other reasonable period which should be sufficient to get out for example of a typical elevator ride - for example from the time the phone has detected the situation), and preferably after that time and/or for example only after the user tries to actually open the phone again, the phone preferably first checks automatically if it is still in the closed space for example by sending preferably short (for example a few millisecond or less or the minimal pulse size which the phone is capable of sending and detecting and preferably with low energy -for example the lowest level of energy in which the phone can communicate for example with a close cell) or for example more preferably sending an even lower power test signal for example by using short-range bluetooth or UWB for example if the phone is able to use and detect these types of signals anyway for example for communication with such types of headsets) and preferably checks automatically if there are still strong reflections of its own signals that indicate that the phone is still in the elevator or similar structure (for example by sending a special wave pattern or for example digital sequence of data and/or other characteristics and/or for example the same type of encryption which it preferably uses with wireless headsets in order to recognize more easily the reflections of its own transmissions and/or for example by recognizing the timings of the reflections as almost instantaneous with the time of sending the pulses, so that for example even if one or more other phones are doing 24/12/08 Yaron Mayer & Haim Gadassi 15/304 the same testing in the elevator their pulses will be sufficiently at different times, so that if for example the phones send the pulses for example for a few milliseconds each time thus reducing the chance that they will be sent at the same time, and/or for example if the phone is receiving reflections of another phone which do not correspond to its own transmission then preferably it waits for example for a few more seconds or other reasonable period before trying to send again for example test pulses in order to avoid interactions between the other phones, and/or for example by using the normal means which are typically used to avoid interactions between nearby cell phones for example when using the normal cellular communication or for example when communicating wirelessly with headsets). Another possible variation is that for example after the phone identifies that it is in an elevator and disables communication it preferably records the level of signals that it can receive for example from the nearest cells and preferably also remembers the normal levels that were before entering the elevator (for example a few minutes before that) and for example continues to test it for example after 1 or 2 minutes or other reasonable time or for example within short intervals (such as for example every few seconds or other reasonable interval) and preferably decides that it is no longer in the elevator for example after the signals become much stronger again or similar to the levels that were for example a few minutes before the elevator condition began or for example above a preset threshold that is typically substantially stronger than the signals from the cells can be typically heard elevators, which is more preferably since this sensing is passive and does not require even low radiation testing for example within the elevator. After this preferably the phone tries again to make a link with cells and/or respond to their queries and/or allows the user to resume cellular communications preferably only after the automatic test indicates that the phone is no longer in the closed metal box or similar structure. Preferably this feature is made required by law for example like the required safety mechanisms that stops the radiation immediately when people open a microwave oven by mistake without first turning it off, and/or preferably the law is corrected to require putting warning signs preferably on elevator doors, reminding people that it is extremely dangerous and forbidden to use the cell phone inside the elevator, and preferably the dangers of talking on a cellphone in an elevator are published in preferably any possible way, and/or preferably people are for example allowed and/or encouraged for example to fine other people or to sue them for example if they talk an a cell phone when riding with them in an elevator and/or refuse to close it immediately - for example like people are encouraged in some countries for example to fine or sue people who smoke next to them in at least some types of public places, such as for example coffee houses or restaurants or offices or for example non-smoking areas in public transportation, thus forcing them to become passive smokers. Another possible variation is that for example instead or alternatively talking on cell phones in elevators can be allowed for example if the elevator owners install for example a pico-cell for example above the roof of the elevator, so that for example inside the elevator there is a low power antenna that enables cell phones to talk with it preferably at the lowest energy level which they can use such as for example when they sense that they are very close to a cell, and preferably on the outside of the elevator the pico-cell communicates with other cells of the cellular networks. In this case preferably there is clear indication that in such elevators that this is an elevator with a pico-cell that enables talking on the cell 24/12/08 Yamn Mayer & Haim Gadassi 16/304 phone inside the elevator with much less danger, and preferably there are also automatic safeguards that protect users for example from situation where the pico-cell might be for example not functioning for some reason and then users might be exposed again to very high levels of radiation without even noticing it. This is preferably done for example by having to install at least one cellular radiation level sensor in the elevator preferably on the inside which preferably starts to beep or speak immediately a warning for example if the cellular radiation level exceeds a certain level and/or for example a device that automatically monitors the pico-cell and preferably immediately issues a preferably auditory and/or also visual warning for example if there is ainy indication that the pico-cell is not functioning properly, and/or for example at least some elevators preferably have and/or are required to have at least one such sensor anyway even if they don't have a pico-cell - for example in order to warn users that didn't notice that someone is talking on the cell phone next to them and/or to warn the people who use the phone in the elevator.
Another possible variation is that preferably the pico-cell which is for example on the roof of the elevator or for example on the cable for example at some distance above the elevator's roof preferably talks for example with an additional pico-cell which is preferably for example at the top of the elevator shaft (since otherwise the first pic-cell might still have a similar problem for example if thee elevator shat itself is also blocking most of the radiation), and preferably for example the room at the top of the elevator shift preferably at least has some openings that allow cell phone wireless radiation to go through more easily.

Another possible variation is that preferably for example the dashboard or other parts preferably in the internal front part of the car contain preferably multiple electrical sockets, preferably with different standard voltages and/or different maximum currents, for example for connecting various typical external devices, and/or for example there is at least one additional socket with changeable voltage and/or changeable maximum current (for example with one or two buttons like in variable transfonners, or for example controlled through for example RFID or EPROMM or for example through a digital code within the cable or the plug of the external device that connects to the socket, so that for example different devices or plugs can for example automatically draw a different voltage from the same socket as needed, or through programming for example through the car's computer, so that preferably the changeable sockets are powered for example by a step-down element in the power supply so that it can for example supply 48 volts (or for example higher maximum voltage) and go down to lower voltages as needed), so that for example various external devices can be easily connected. So for example if the user wants to connect a mobile computer, preferably at least one of the standard sockets or the changeable socket can be used for example for connecting directly to the computer the same power that comes out of the transformer that typically seats on the cable that connects between the computer and the wall (which is much better then normal cars, in which the user typically has only 1 or 2 electric sockets from the lighter socket, which have only one available voltage and so for example for connecting a mobile computer the user typically has to connect first a device that boosts the voltage to 110 or 230 volt and than connect to it the normal electric cable of the mobile computer, which contains the transformer that lowers it again), and/or for example there are preferably at least some additional similar sockets for example 24/12/08 Yaron Mayer & Haim Gadassi 17/304 also in the middle and/or back of the car (for example at the back of the front seats or for example on a protrusion from the floor between the seats) so that they can be easily accessed for example from the back seats. However, preferably this is accompanied by appropriate means for securing the various external devices in a firm way so that they don't fly around the car for example in the case of an accident or sudden stop - for example by special belts or hooks that can attach them preferably firmly for example to the back of the front seats or for example to the bottom between the seats. All of these sockets preferably get their power from various cables that come out of the power supply as explained above. Another possible variation is that preferably the power supply contains also an element that can generate for example directly from the power batteries for example also a standard AC current of for example 230 or 110 Volt or similar voltages, which preferably is connected to at least one such socket, so that preferably this can be used also for connecting standard home electrical appliances which expect for example 230 or 100 Volt AC or similar voltages. Another possible variation is that the car preferably has for example on or near the front panel for example in front of the passenger that sits next to the driver and/or for example on the back of the front seats for example standard connections for example for connecting a keyboard and/or for example an LCD screen, so that for example the other passengers can interact more intensively with the car's computer while the user is driving and/or for example the car computer can enable such monitors to connect directly remotely for example with computers for example at work or at home (for example through cellular or Wifi or Wimax Internet or similar technologies), so that for example passengers can use the time more efficiently. Another possible variation is that preferably the car contains an improved internal communication network for example consisting of more than one data line and/or at least one analogue data line and at least one digital data line, preferably with multiple add/drop capabilities.
However, the car preferably still has an alternator like in normal gasoline car or a similar device, since this is needed for the automatic recharge during breaking or for example when going downhill in a neutral or similar mode, but preferably the engine itself can be used also as an alternator for example by reversing its switching (i.e. for example using at least some of its coils or special additional coils that it has for this in reverse so that preferably it also functions like a DC device in this state), so preferably there is no separate additional alternator, as explained also elsewhere in this application, or for example there is also an additional for example small separate alternator which is preferably activated for example only in case of emergency or under special circumstances. However, in the electric car the alternator (which is preferably the engine itself acting as alternator) preferably recharges mainly the main power battery or batteries, but preferably when activated it also recharges automatically the small front battery for example if it senses that it is not full enough for any reason or if there is a malfunction with the power batteries or with the power supply, and/or for example the small front battery is also connected for example to solar panels which are for example on the front hood and/or for example on the car's roof. In addition, preferably the car has various failsafe mechanisms in case of power failure or for example software failure, so that for example there is a separate watchdog application which for example checks every second or less or for example every few seconds or other reasonable time if the power and/or various software applications are functioning properly and in case 24/12/08 Yamn Mayer & Haim Gadassi 18/304 of malfunction it can for example immediately activate other failsafe emergency functions and/or can for example automatically return at least some systems to more direct manual control, and/or for example automatically neutralize or disengage the engine and/or for example apply the brakes, preferably gradually, and/or for example in case of serious function or power failure the engine can become automatically disengaged and/or the brakes automatically start to brake preferably gradually, for example by a spring or air pressure or hydraulic pressure mechanism in which when there is no electrical force active against it the natural action is preferably gradual turnoff. Another possible variation is that for example in case of discovering various important or dangerous bugs in the car computer's software (for example in the Operating System and/or in various applications, for example like in PC's with Windows) and/or for example in the firmware (and/or for example in other elements in the car) and/or for example in the course of offering various additional improvements once in a while, preferably one of the options of updating them is for example through the recharge posts or rechargers network, so that for example when connecting to the recharger or recharge post, the messages from the service provider's main computers can include for example warnings about required patches or software or firmware updates and/or for example an announcement of an improved version and an invitation to download it, and then preferably the driver can for example allow the software or firmware update for example through the communication with the recharger or recharge post (preferably the display of this type of messages and the user confirmation are done through the car computer's display, and then preferably the car computer can download it from the recharger or recharge post and install it). Preferably such updates can be issued for example by the service provider and/or for example by the car manufacturer, which is using the service provider as a channel for fast distribution of for example at least some updates (which is preferably based on the car automatically providing also details about its manufacturer and/or model and/or preferably also for example manufacture year when connecting to the recharger or recharge post, and/or for example the unique code of the car already includes also a part that represents the code of the manufacturer and/or model and/or manufacture year. However, this is preferably accompanied by tight security, such as for example encrypted digital signatures so that the car's computer preferably refuses for example to accept any updates that are not digitally signed properly for example by the service provider or by the auto manufacturer, and preferably no automatic update is done without requiring clear explicit confirmation from the user. Another possible variation is that for example various such updates can be similarly downloaded for example through the Internet for example through secure servers in the site of the service provider or for example the car manufacturer, and downloaded to the car's computer for example through a flash memory stick (for example through a USB connector or for example firewire or similar interfaces) or similar mobile data devices or media. In addition, preferably whenever applying updates for example by any of the above methods, preferably in case of malfunction or some problem in the update process preferably the user can press for example a reset button which preferably automatically returns the car's computer to the state it was before the update, and/or for example there is a separate self monitoring element in the car's computer that can detect such problems automatically and can for example revert to the previous state automatically, preferably together with an automatic announcement or other indication to the user, 24/12/08 Yaron Mayer & Haim Gadassi 19/304 and this reset or reverting is preferably done for example by keeping automatic snapshots of the previous stable conditions and restoring from them when needed.
(Preferably the above methods of updates can also be used for example for downloading new sounds or for example elements for the sound simulations). The automatic cutting off of the circuit of the high power batteries for example in case of an accident as described above can preferably be done for example by preferably using the same type of sensors that are used for example for detecting crashes in air bag systems, and when the sensors detect a serious crash preferably they can disconnect the circuit for example by issuing a command to disconnect for example by using the same multiplexers that are preferably used for serial rerouting during recharges as explained above, or for example they cause an air blast in a preferably small compartment area where a part of the circuit is connected for example by a thin metal conductor film or other blast sensitive element, which then for example becomes torn apart by the blast. The automatic preferably instant disconnection can be done for example between the batteries and the car and/or for example between the batteries themselves and/or between elements in them. Another possible variation is that for example the battery compartment in the car has one or more preferably small air bags which in the case of an accident preferably inflate automatically and thus both protect the batteries against mechanical shock and act as isolation. Another possible variation is that for example in electric cars (preferably especially in systems where all 4 wheels are connected to the engine but also in normal 2-wheel drive) preferably for example when the user is trying to apply the brakes the car's computer can for example automatically calculate and adjust the speed of rotation of the wheels to fit to the speed of movement of the car even for example if one or more wheels are temporarily in the air (so that preferably for example the car's computer preferably senses the change in that wheel's speed compared to the other wheels and/or the fact that it is in the air and changes the speed of the wheel that is in the air for example to match the speed of the wheels that are on the ground), thus increasing braking efficiency and reducing the need for ABS and/or improving its efficiency, so that there is less chance for example that the wheel that was in the air will become locked when it hits again the ground, which is preferably based on the electric engine's ability to respond to speed changes much faster then a gasoline engine (and/or this is done for example in combination with automatically reducing or increasing temporarily the pressure of the brakes on the wheel that is in the air). Another possible variation is that for example at least in one mode the car's computer can preferably automatically decide for example if to use the engine power on two wheels or on 4, for example based on automatically sensing the flatness of the road (for example based on sensing the pressure on each of the wheels), so that for example 4 wheel drive is automatically activated only if the road is for example bumpy or uneven beyond a certain level and/or for example according to automatically sensing for example the amount of friction on the road and/or additional parameters, thus preferably saving energy when 4 wheel drive is not needed. Preferably the switch between 2-wheel drive and 4 wheel drive is preferably done for example by automatically activating or deactivating for example a relay that reaches the second set of wheels or for example by electrically activating or deactivating a second preferably small electrical engine which is connected to the second set of wheels.

24/12/08 Yaron Mayer & Haim Gadassi 20/304 Another possible variation is that preferably at least some electric SUVs can be built for example with wheels on special poles and/or for example more free or wider range suspensions which preferably enable the wheels for example to be automatically and preferably instantly pulled up or down for example by the car's computer or by the more free suspension based on the conditions of the surface, so that preferably the car can remain preferably in the same horizontal balance or for example in some other preferably stable inclination (so that for example the wheels are preferably automatically moved up or down as needed in order to keep the car in said horizontal or other balance, thus for example correcting inclinations as they starts to occur) and this way there is preferably also less pressure on the chassis than in normal SUVs, thus preferably also enabling the car to be built from lighter materials, and/for for example the chassis is built with strong hollow tubes such as for example based on aluminum and/or carbon fibers (which preferably are designed in a 3d network structure, including for example also vertical and/or diagonal tubes) and/or example if the SUV is bigger than a normal car like in gasoline based SUVs in order to enable it also to carry additional weights and/or for example it is not an SUV but is a commercial pickup car, preferably the electric SUV or pickup car preferably has for example an additional middle hinge with wheels (thus having for example 6 wheels instead of 4), and/or for example has only one additional 5d, wheel, but this wheel is preferably located in the center of the car for example both lengthwise and widthwise, thus enabling better support to the middle of the chassis, which preferably again means that the chassis can preferably be made of lighter materials, and/or for example on the front wheels hinge and/or on the back wheels hinge there can be for example an additional wheel for example in the middle widthwise between the two normal wheels, with also has the advantage of enabling better stability for example over bumps or holes in the road - for example if it is preferably accompanied for example by better springs or suspensions thus preferably allowing the relevant wheels more freely to go up or down to adapt themselves for example to bumps below them.

Another problem is that since electric cars can be much more silent than gasoline powered cars, it can be dangerous if people walking nearby in the street do not notice the car. So preferably the car includes proximity sensors than can detect for example nearby people and/or small children or animals (for example by computerized analysis of video camera input and/or for example ultrasound and/or for example infrared and/or similar technologies) and if for example they are too close, for example walking on the side of the street a few meters in front of the car (preferably even if not in a collision course) and/or similar sensors, so that preferably for example the car's computer can automatically decide in certain situations for example to generate for example a simulation of for example a normal noise of a car or for example can automatically sound the horn and/or other auditory and/or visual indicator (such as for example flashing or dancing colored lights which can for example reflects from objects in front of the person even if he/she is walking in front of the car with his/her back to the car) that can draw people's attention that the car is passing by. Another possible variation is for example that the user can preferably choose from a list of available sounds of cars, such as for example Ferrari or Harley for playing during the drive, as Shai Agassi has now suggested in Businessweek on Aug. 6, 2008 and as has been suggested already on 24/12/08 Yaron Mayer & Haim Gadassi 21/304 Feb. 19, 2008 on http://www.cheersandi!ears.coni/forumslindex.nhu?s=
e9be7f57dc15U02ca05b18d37ef904d3&showtoAic=226i39&st--0&u=369571 &#en try369571. However, since merely making such a noise might be confusing and even dangerous if it is not properly correlated with the car's actual performance (since for example in normal cars people typically associate the type of noise and/or its level with the car's speed and/or distance), preferably this is improved so that the engine noise is simulated for example by the car's computer based on the actual speed and/or acceleration of the car and/or other parameters such as for example the theoretical gear position that would be typically used at such a speed and/or acceleration in a gasoline powered car (preferably this is done for example by using appropriate "phonemes" or other preferably basic elements of the simulated sounds, for example in a way similar to creating various musical instruments simulations when playing MIDI music files, and/or for example by automatically switching between different recorded sound files according to the current state of the car, such as for example playing the acceleration noise during acceleration and playing the appropriate recording according to the speed, and/or for example automatically increasing or decreasing the volume of the sampled sound and/or its speed and/or pitch and/or other parameters according to the current state of the car).
(This can be also done for example by a separate dedicated device, but that means that it would have to constantly get these parameters from the car's computer) In addition, preferably the driver can control the volume of this sound for example as one general volume level (for example by moving a physical or digitally simulated lever or turning a physical or simulated button) and/or for example by specifying the minimum and maximum levels (so that for example even at high speeds the sound level will not exceed a certain maximum), and/or for example the driver can control for example two or more separate sound levels - for example one for the sound that will be heard inside the car (for example by controlling the volume for playing in internal speakers, if for example the driver prefers also such sound feedback for himself/herself, for example based on previous habits of driving normal cars or for example silencing the internal sound simulation altogether), and one for the sound that will be heard outside the car, for example generated by one or more external speakers for example in front of the car, for example near the headlights or for example under the front hood (this speaker or speakers are preferably directional and preferably point for example forward, or for example at an angle forwards and to the right, so that the noise is heard mainly by people in the nearby sidewalk or in front of the car and less by people behind the car or for example on the other side of the street or for example above the car, thus preferably avoiding for example noise to nearby apartments, and for example, if an angle in used, in places where the driving direction is opposite such as England the angle is preferably instead forward and to the left), and preferably also a small rear speaker for example for warning people for example when the car pulls out of parking in reverse. Another possible variation is that for example when driving in inter-city highways, where there are no pedestrians walking, the car's computer automatically squelches these sounds or at least makes them significantly lower, for example by digital signals or sensors that tell the car if this is an inter-city highway or a normal road (for example by using road signs or traffic signs which also automatically broadcast for example constantly or for example every second or other short interval for example a wireless preferably digital message which tells the car for example if it is entering an inter-24/12/08 Yamn Mayer & Haim Gadassi 22/304 city highway or for example entering an urban area), and/or for example this switch is automatically done according to speed (so that for example from a certain speed and upwards the air resistance itself makes sufficient noise and so the computer can automatically reduce or turn off the simulated noises), and/or for example the driver can for example change a lever or other control which switches between inter-city highway mode to normal mode, so that for example in the highway mode these sounds are automatically lower or for example silenced or for example use a different program or different set of rules. In addition, preferably the driver can also control for example the pitch of such simulated engine sounds and/or for example the computer preferably automatically removes annoying components from the simulated sounds, such as for example high pitched sounds which annoy and are not needed for drawing the attention to the car (which is preferably done for example by removing them once in advance from the recorded samples or phonemes and/or by automatic dynamic filtering as needed when the sounds are simulated), and/or for example the car's computer can automatically adjust the sounds or their level for example also based on other parameters, such as for example if it is daytime or dark (for example based on a clock and/or on light sensors) and/or for example based on the level and/or types of other background noises in the area. Preferably at least by default the sound level is lower than the car sound it simulates, so that it is less annoying, but sufficient for alerting pedestrians or animals, and/or for example the sound is intermittent - for example going on and off every second or other reasonable short interval. Another possible variation is that preferably the user can for example choose from a number of available noise-increase profiles that enable for example the noise to increase with speed at a rate lower than in the real simulated cars, since there is no need to make the noise as loud as the original cars as long as it is sufficient for pedestrians to notice the car, and/or this is preferably the default, and/or for example the user can set a maximum noise or a maximum speed after which the noise does not further increase with increasing speed or for example even automatically starts falling off and/or stops since as explained above at certain speeds such as for example 60 Mph the noise of the wind resistance makes the car noticeable enough or can become even louder than the simulated engine noise even in normal cars. Another possible variation is that the car's computer can for example at least in one of the modes for example use the internal speakers also for example for anti-noise - for example for automatically counteracting the wind noise when the user is traveling for example at high speeding in inter-city highways, so that the user can have a more controlled sound environment. Another possible variation is that the user can choose for example from a set of various car simulations and/or additional types of noises - preferably independently for different elements or stages, so that for example the user can choose for example the acceleration sound of for example a Ferrari (and/or for example some other type of sound effect, such as for example other natural or artificial types of sound) and the driving sound of some other car (and/or for example some other type of sound effect) and/or for example some car (or for example other type of sound effect) for low speed driving and another car (or for example other type of sound effect) for high speed driving, and/or can for example at least for some sounds choose also different sound effects for example to be heard inside the car and different sound effects to be heard outside the car, etc. This can be done for example by showing the user a separate menu for each stage or for example a unified menu in which the user 24/12/08 Yaron Mayer & Haim Gadassi 23/304 can mark for example which element or elements to use for which stage or stages, and/or for example the car's computer can offer the user various pre-defined recommended profiles or profiles of recommended combinations, for example with pre-selected or pre-marked options which the user can for example accept or adjust.
The transition between the various car type simulations or types of sound effects can be done for example abruptly when the car switches between these states or for example based on gradual fade-in and/or fade out. Another possible variation is that the noise can be generated for example by preferably simple one or more add-on devices which can be for example attached to external mirrors or some other protrusion in the car and generate a certain amount of noise for example by one or more elements which are affected for example by wind resistance and/or by vibrations, such as for example one or more small for example rubber bands that wiggle in the air or for example a small wheel or rattler that rotates in the wind, and preferably the device contains also an automatic cap or cover which for example beyond a certain speed becomes automatically locked for example by the effect of the air resistance, thus preferably stopping the noise beyond that speed, and preferably the device is small enough so that its effect on creating air friction is minimal, and/or for example such devices are controlled also at least partially electronically and can respond for example to the wind speed to sense the speed of the car for example in order to activate or deactivate or for example change the sound level or its type for example based on the,speed. In addition, preferably local governments and/or municipal authorities will preferably enact laws or regulation which limit the sound levels and/or for example the allowed types of sound and/or for example the allowed pitch of such simulated sounds, so that drivers do not use unnecessary simulated noises (for example to "show off") beyond a reasonable level that is sufficient to warn pedestrians, so that for example the sound is preferably required to be for example at or above a certain minimum level and below a certain maximum level, for example when the car is moving below a certain speed, and preferably the regulation also determine for example what types of sound effects are allowed. Another possible variation is for example using a visual conspicuous indicator such as for example colored flashing lights. Another possible variation is that for example pedestrians can buy a preferably cheap device such as for example a small sensor or RFID (which preferably costs less than a few dollars) which can for example be coupled to a wrist watch, which for example transmits a certain wireless signal when probed by an automatic transmission from a nearby passing car so that the car can automatically sense the nearby person and make the auditory warning, or which for example makes a preferably small noise itself when receiving the wireless broadcast from the car. Another possible variation is that if the car for example has one or more video cameras as sensors, preferably this can be used also for additional features, such as for example automatically lowering strong dazzling lights to normal lights for example when the sensors sense that one or more cars are coming in from the opposite side (for example by sensing their headlights and the distance of the opposite car for example by the brightness and/or by the distance between the two headlights). Another possible variation is that the user can also choose for example from a set of more than one available horn sounds, however these are preferably under strict standards so that the user can only choose from officially allowed standard sounds. Another possible variation is that there can be for example at least two different types of warning sounds which are for example 24/12/08 Yaron Mayer & Haim Gadassi 24/304 the default at the same time, so that for example the horn sound for warning is different for example from the horn sound when the user for example intends to alert for example another driver for example in the street lights that the light has changed. This is better than the prior art in which there is no differentiation between sounding the horn for warning of imminent danger and sounding it in order to make the car in front move, and so every sounding of the horn can be stressing and confusing. This is better done also in normal cars, and preferably by setting official standards for the allowed set of sounds for each of these two uses. Preferably similar variations of sound effects are also available for example for electric bikes or motorcycles, except that the available sound effects are preferably more similar to the typical sound of bikes or motorcycles and there is less ability to separate between internal and external sound effects (except for example if some sound effects are displayed for example inside the helmet).

Of course like other features of this invention and as explained also in the glossary and clarification section, these features can be used also independently of any other features of this invention.

In addition, preferably while recharging the batteries serially preferably the recharger takes into account various measurements and/or various relevant parameters of the individual batteries or elements which are being recharged serially, such as for example their temperature and/or age and/or voltage and/or their behavior during the recharging, and preferably adjusts the recharging parameters (such as for example the voltage, current, pulses and/or duration of the recharge) preferably according to the weakest battery or element in the series.
Preferably each battery or relevant ele'ment contains a microchip which automatically determines or measures the relevant parameters, preferably including also for example how much current went in and out of the battery during its lifetime and/or for example how many times it has been already recharged, and preferably these microchips can communicate the information about the relevant parameters preferably digitally to the recharger and/or to the car, and/or preferably they can also be displayed automatically for example on a small LCD screen coupled to the battery or on the car's display through the communication with the car's computer, as explained below, and/or this parameters can preferably include also for example the manufacturer, preferably exact model, and/or various other parameters, such as for example year of manufacture and/or for example the maximum current and/or voltage and/or peaks that can be handled during recharge. Another possible variation is that for example when such electric car batteries are replaced and recharged at the service station, preferably the batteries or relevant modular elements are preferably automatically sorted by the relevant parameters (preferably by one or more computers which read the parameters automatically directly from the relevant microchips and sort them for example by automatically dropping the batteries over different conveyor lines), so that preferably they are grouped automatically into preferably more or less homogenous groups, so that for example batteries or elements which are in a similar state or have similar relevant parameters are preferably grouped together (which means of course that if for example there are also different models or types of batteries for example with different recharge parameters or different behaviors then this is preferably also taken into account in 24/12/08 Yamn Mayer & Haim Gadassi 25/304 creating the groups), and then preferably each group is recharged separately (preferably in a separate serial row for each group and preferably the recharging in each group is for example optimized according the average parameters of the group or for example according to the weakest batteries in the group) in order to improve the efficiency of the recharging of the batteries in that group. So for example if an average service station services for example on average around 1,000 cars per day and if for example each car contains for example around 20 batteries, this means that for example the service station preferably has for example at least 200 parallel productions lines which can each for example recharge for example up to 100 batteries serially (or for example 100 production lines that can each for example recharge for example up to 200 batteries serially, or for example 400 production lines that can each for example recharge for example up to 50 batteries serially, or other reasonable combinations), so that preferably for example the entire 20,000 batteries can be recharged together at the same time, preferably during night hours, and so preferably for example if each battery has for example a voltage of 12 volts, this means that each group of for example around 100 batteries is preferably recharged for example at around 1200 volts or for example each group of for example around 150 batteries is preferably recharged for example at around volts or for example if each battery has for example a voltage of 12 volts, this means that each group of for example around 100 batteries is preferably recharged for example at around 1200 volts, or for example if each battery has for example a voltage of 50 volts, this means that each group of for example around 40 batteries is preferably recharged for example at around 2000 volts. This way there is the advantage that preferably a much smaller number of rechargers is needed compared to when recharging each individual battery or cell or unit separately, and there can be much less current and heating and losses problems, and yet each homogenous group can preferably be recharged almost optimally. The multiple serial rechargers are preferably stacked together for example in parallel preferably both sideways next to each other and to the height - one above the other, to allow better use of the available space. After the recharging preferably the batteries are automatically collected preferably in a way that preferably mixes together batteries of the different groups in order to improve the statistical behavior of the batteries in the car, so that for example when the recharged batteries are inserted back into cars that come for service for example the next day preferably there is a good mixture of batteries from various groups, for example by random mixing or for example by automatically collecting for example each time one battery from each group for example while choosing automatically an order that creates a good mixing, which is preferably done for example by another computer or computers or for example by the same computer or computers that also sort incoming batteries into groups when they arrive for recharging.

Another possible variation is that the user can for example add a preferably small measurement and/or control unit for example to the electrical switchboard for example in the home on in the office, which preferably can measure automatically the current levels (for example by shunt resistor and/or for example induction coils around the electrical wires, and/or for example hall effect sensor or sensors) and for example the user or the installing electrician tells it the maximum allowed amperage and/or the unit for example senses this automatically for example according to 24/12/08 Yaron Mayer & Haim Gadassi 26/304 various features of the switchboard or can for example read this digitally from the switchboard, and preferably this unit measures preferably all the time or at close intervals the actual amperage for example in the house or office and/or in the building and can preferably for example broadcast this information for example to the car recharger unit for example through wireless radio transmission or for example through transmitting information over the electrical wires (and/or for example the car recharger unit can also preferably measure at least part of these parameters itself), and then preferably the car recharger unit preferably takes into account these current measurements in order to be able to preferably automatically reduce its recharge power and/or speed so that preferably the total current consumption in the house or office for example preferably does not exceed and preferably remains sufficiently below the maximum allowed amperage which would cause the fuse to jump, such as for example 40 amperes in normal 1-phase home electrical supplies or for example 40-60 amperes in houses with a 3-phase system.
This has the advantage that this way preferably for example cars with Ml batteries or similar fast recharging batteries or other fast recharge devices such as for example one or more super capacitors such as for example EEStor can preferably be recharged dynamically at preferably the fastest rate available, with dynamic fitting to the place where it is being recharged so that it can preferably be recharged at the most efficient available level for example whether it is being recharged in a normal home 1-phase electrical outlet or a 3-phase home or office system, or for example at the service station, where it can preferably be recharged for example even at speeds up to a few minutes recharge. Since according to http://www.stanford.edu/group/
greendorm/participate/cee124/TeslaReading_pdi the Tesla electric car for example needs about 110 watt-hour for each kilometer and for example the GM EV1 needed about 102 watts-hour for each kilometers at a typical speed of about 90 Km/hour (which is about 13-15 horse powers) and the EV1 could go about 80-100 miles after a night recharge, this means that for example an EV1-like car which is charged at a normal single phase house electrical outlet would typically need about 8-10 hours at night for a full recharge, while a more advanced car with for example Ml or similar fast recharge batteries or other fast recharge devices such as for example one or more super capacitors such as for example EEStor with sufficient capacity to run for example up to 200-300 miles after recharge would require for example 8-10 hours at night with a 3-phase electrical outlet, and of course a higher output system can be recharged even faster. However, there is also another problem for example in homes, since unless it is for example a villa in the suburbs, a normal multi-apartment building in the city does not have convenient connection for recharging a car in the garage or parking lot from the electrical outlet in the apartment, and similarly for example in offices in multi-storey buildings where the car is parked typically in a parking lot in the basement. So preferably this is improved so that for example office buildings and for example people in apartment buildings can preferably request for example from the electrical company to prepare one or more recharge outlets preferably in the parking lots, which are preferably connected directly to the building's electric switchboard, which is typically also at the basement or ground floor level of the building, typically near the area of the parking. Preferably these outlets are at or near the parking lots and are for example personal outlets which are logically or physically linked to the electrical counter of the specific home or office and can be used only by the allowed user or users for 24/12/08 Yaron Mayer & Haim Gadassi 27/304 example with the help of a mechanical and/or electrical lock and/or for example RFID technology and/or similar preferably password and/or key protected technologies, and/or for example even more preferably such recharge outlets are public and so can be preferably used by anyone in the building or for example by outsiders and/or are for example made available for example by the electrical company or for example by the municipal authority for example also on streets and/or for example near at least some streetlamp poles and/or electric power poles (which means that at least some of these recharge posts are preferably coupled to these poles or at least receive their energy directly from them), and are preferably operated for example by inserting a credit card or for example smart card as explained above, and preferably for example when the cable is removed from the car a new insertion of credit card is required, and/or for example only the card holder can authorize removal of the cable from a car that is currently being recharged for example unless the recharge has ended (to prevent stealing a public recharger or recharge post away from someone else who is currently recharging), which is preferably done for example by mechanically locking the cable's plug for example automatically in the car (or for example automatically in the recharger - if the plug comes from the car into a socket in recharger), so that the lock is automatically released only for example when the recharge has ended (i.e. for example the battery is full or for example the decided amount of recharge has been reached, as explained below) or for example if the user for example enters or passes his/her smart card again or for example re-enters his/her password in order to stop the recharge and disconnect prematurely, and/or for example the user can press a button or lever inside the car which releases the lock, and/or for example the car's computer automatically decides to release the lock for example under certain conditions. Another possible variation is that the user can for example release the lock that keeps the cable plugged-in for example through his/her remote car-lock and/or alarm control - so that for example by pressing the button in the remote control that unlocks the car the lock that keeps the plug in place is also released (and/or for example there is a special separate button on the user's remote for releasing the plug's lock) - preferably for example by causing the car's computer to send an appropriate command the recharge post through the data line (for example if the cable comes out of the car into a socket in the recharge post) or for example to automatically release the lock directly (for example if a cable comes for example from the recharge post or for example from a fast recharger to a socket in the car) and/or for example by quickly passing an RFID or smartcard or other device for example at or near the recharge post (but preferably anyway if the user for example lost the relevant device he/she can also simply tell the computer for example from inside the car for example to instruct the recharge post to release the cable). Another possible variation is that for example if a certain time (such as for example

2 or 3 minutes or more or other reasonable period) has passed after releasing the lock and the user has not yet pulled out the plug and/or for example more preferably if the user for example locks the car again with the remote while the plug is still connected, preferably the plug becomes automatically locked again, for example by the car computer automatically sending the appropriate instruction to the recharge post for example through the data link. Another possible variation is that for example if the user tries to pull out the plug before the lock is released preferably the recharge post for example issues an automatic warning for example through a 24/12/08 Yaron Mayer & Haim Gadassi 28/304 visual display and/or for example through synthesized speech or pre-recorded message - for example warning that the plug is still locked and/or also reminding the user preferably how it can be properly released - for example that it should be released for example by pressing he appropriate button in the car's remote control or for example by pressing the relevant control for example inside the car or for example by other available means (which means that preferably the recharge post can not only sense cases where the plug is pulled for example with a strong force for example above the threshold for forceful removal as explained elsewhere in this application but can also sense for example a normal force which people for example typically use for example for removing the plug normally - for example by using one or more switches for example at the bottom part of the socket so that for example the same switch can sense at least two separate amount of displacement or for example at least two switches respond to different amounts of movement of the plug, so that for example if the plug is pulled only the minimal movement that can be made for example with normal force (for example 1 mm or other reasonable distance) for example only the first switch is for example activated or released for example by being un-pressed and for example the more forceful movement beyond the threshold (which creates for example a movement of 3 mm or other reasonable threshold) or for example activates or releases the second switch, and preferably even for the smaller displacement caused by normal force preferably the elements that lock the plug also flexibly bend a little so that for example as soon as the user stops pulling the plug it preferably automatically snaps back into its deeper position thus stopping for example the warning display), and/or for example when the plug is locked there is for example a red or other color light that lights up a message such as for example "Cable locked" or for example "plug locked" or for example similar wording for example at the top part of the recharge post, and/or for example if the user tries to pull out the plug while it is locked for example this light begins to flash or for example the recharge post for example beeps or makes another sound that reminds for example new users that the plug is locked and needs to be released first.
Another possible variation is that for example when the lock is released for example the recharge post or for example the remote control preferably indicates this automatically for example by visual and/or auditory indication. Of course like in other places in this application, various combinations of the above and/or other variations can also be used. The above variations have the advantage that it can work easily and automatically also for example if the recharge post does not have its own external user interface and relies on the data link and for example on the user interface of the car's computer for the communication with the user - as explained elsewhere in this application as one of the possible variations, and this way for example even in such a case preferably the user can release the cable without having to go into the car and do something and then go out again and physically release and retract the cable, and/or similarly preferably for example if the user needs to relay any information or for example request to the recharge post for example before starting the recharge preferably the user can for example enter the information or request for example in advance through the car computer's user interface and then preferably when the user connects the cable to the recharge post preferably the computer automatically sends the data or request to the recharge post preferably through the data link, so that preferably the user does not need to go back again into the car after connecting the cable even if the recharge post does not have its own 24/12/08 Yaron Mayer & Haim Gadassi 29/304 monitor or keyboard, and/or in such case preferably for example if the service provider's main computers need or want to send some messages to the user for example at the parking place even if they are for example from the recharge posts they are preferably sent through the normal direct cellular or other wireless communication between the service provider's main computers and the car's computer, so that the user can preferably receive the message before exiting the car and connecting the cable. As explained also elsewhere in this application, for example in this case preferably the user can simply plug the cable in the recharge post and the identification of the car Id is preferably automatic through the data link, and the user can be for example required for example preferably. before even plugging the cable and before exiting the car for example to enter a password or pass a smart card or similar device for example through the car's computer terminal (for example in order to make it harder for car thieves to charge the car), or more preferably the user does not have to enter any password and for example if the car was reported as stolen then the recharge is automatically blocked for example through the service provider's main computers (for example through a remote preferably encrypted instruction to the cars computer or to the recharge posts), and/or for example the user has an RFID for example in the remote control so that for example as long as the remote control is nearby the user is verified automatically for example by the car computer). In case the remote control can be used to release the plug's lock as explained above, preferably locking the car again with the remote preferably also causes the plug to become locked again and/or for example the user has a separate button on the remote for locking again the plug, and/or for example as a safety measure preferably for example if the lock has been released but the user does not physically remove the plug for example within 1 minute or other reasonable time, preferably the plug becomes automatically locked again.
Another possible variation is that for example if the cable comes out of the car to a socket in the recharge post, preferably for example an additional button on the user's remote control or for example a control from inside the car can also for example cause the socket to actually release the plug (for example through an automatic command from the car's computer to the recharge post) and preferably once released for example this way or manually preferably the cable preferably retracts automatically into the car - preferably for example by spring or small electric motor, as explained elsewhere in this application, and preferably the preferably small door of the cable's compartment also closes and locks itself automatically after the cable has been retracted. This has the advantage that for example on a rainy day for example if the car has been recharging in an open space preferably the user does not have to start fiddling with the cable but can get immediately into the car. Since there are preferably at least two cables and/or two sockets on the car preferably at the front and at the back as explained elsewhere in this application, preferably the distance that the cable is stretched till the recharge post is small and since preferably the cable is shaped like a spiral phone cord, as explained elsewhere in this application, preferably even if there is mud below and even if the cable is for example automatically fully released from the socket and starts to retract automatically for example into the car preferably the spiral design and the short distance preferably reduce the chance that the cable will for example fall into the mud before retracting into the car even if the user is not holding the cable in the hand while letting it retract into the car. Preferably if the spiral design of the cable has a larger 24/12/08 Yamn Mayer & Haim Gadassi 30/304 circumference such as for example a spiral with a diameter of 5 or more centimeters, then preferably when folded into the car the spiral can be for example pressed into a round hollow tube with a preferably slightly larger diameter than the diameter of the spiral and/or for example the cable is pressed over a smaller-diameter rod in the cable compartment so that preferably the rod goes through the hollow space formed by the internal shape of the spiral, so that the cable can preferably fit easily, and/or for example the cable can be automatically pulled in for example by a preferably thin for example nylon or rubber wire of for example a few mm diameter or less which for example through the hollow space formed by the internal shape of the spiral and is for example rolled back for example on a roller with a spring (or for example small electric motor) for example through a preferably small hole at the end of the tube, so that for example when the cable spiral is released the wire that runs through the internal space of the spiral of the spiral can cause the spiral to contract automatically into its housing preferably for example with a wider funnel at the entrance to the tube, and/or for example the cable goes through a preferably small hole which is preferably bigger than the diameter of the cable but preferably substantially smaller than the diameter of the spiral - for example in the car for example at the entrance to the tube, and for example the tube rotates in order to cause the cable to retract, but that is less preferably since it can for example wear out the cable through friction, and/or for example the cable is rolled for example on a sufficiently large and/or wide roller (preferably by going through a hole preferably at the inner end of the cable compartment which is preferably larger the diameter of the spiral) for example like a non-spiral cable or for example like a spiral cable with a smaller diameter of the spiral. Another possible variation is that if for example despite the automatic lock the recharge cable becomes unplugged anyway (for example due to enabling release of the lock for example if excessive force is used in order to prevent damage to the cable or to the locking mechanism, as explained elsewhere in this application) or for example the electric or data connection is somehow stopped for example in a way that is not supposed to happen normally, i.e.
for example without the lock being properly released (for example because someone has damaged the cable or broken the lock)(which can be preferably be sensed for example by the car computer or recharger or by the recharge post, for example by sensing that the data connection and/or power connection is not working or is not working properly even though there was no lock-release command), preferably this is reported automatically for example by the car computer and/or by the recharge post for example to the service provider's main computers and/or for example the car computer or for example the recharge post or for example the service provider's main computers preferably send the user preferably immediately (i.e. for example within a few seconds or for example within a few minutes or other reasonable period) for example an automatic message about it, for example through SMS
and/or email and/or Instant Message and/or automatic phone call or similar means.
Preferably when the lock is released for example a special indictor for example on the cable itself (for example if the cable comes out of the recharge post to a socket in the car) such as for example flashing LEDs) and/or on the recharger indicate in a preferably visually conspicuous way that the recharge has ended, and then other users can remove the cable and attach it to another car. However, since the relative car priorities might cause the car for example to be recharged for example only at low speed and/or for example cause the actual recharge to start for example only 24/12/08 Yaron Mayer & Haim Gadassi 31/304 after some time - for example only in the afternoon, it might be a while till the recharge is considered to have ended and the lock is released. (This means that preferably the system takes into account also for example the number of rechargers in the area, since if for example initially there are in the area only a small number of rechargers, the system might prefer to finish recharging each connected car as soon as possible even if it has low priority and would be normally for example recharged only in the afternoon - by simply giving it the amount of energy that it needs, if it needs any daytime recharge, in order to release the recharger as soon as possible and allow other cars to connect to it). Another possible variation is that for example after the lock is released the cable can also be automatically retracted for example by the recharger (for example into the car or into the recharge post), but if this is done, this is preferably done for example only if the battery is full or if these are rush hours and/or there is for example a shortage of rechargers in the area, since for example if there is no shortage of rechargers in the area and the battery is not yet full, the system might for example automatically decide to add charge anyway to the car for example when there is less load or for example when a certain lower rate hour has been reached, and in that case it is preferably that the cable remains connected to the car as long a nobody else needs it. This has the advantage that since obviously most people don't need a full recharge every night or at least not during the day, preferably a smaller number of rechargers can be divided between a larger number of users, preferably on a need based first-come service model. Another advantage is that such public rechargers or recharge posts for example in apartment buildings or for example on the street do not have to be limited to the typical limitations of a single apartment and thus can preferably enable using for example higher voltages and/or higher amperage limits, thus preferably enabling a faster recharge time - for example only 2-3 hours at night or even faster. And since typically electric companies in the current prior art typically turn off for example 1/3 up to 2/3 of their turbines during night time hours, this means that for example until about 25%
of the population start using electric cars the electric companies can support this without capital infrastructure changes by simply starting to turn off less turbines at night as needed, and by the time more users start using electric cars, the electric companies will have made already sufficient profits to invest in increased infrastructure as the economy gradually moves into more and more people using electric cars instead of the prior art polluting gasoline cars. Preferably the above or similar principles are used preferably both for only-electric cars and/or for hybrid cars and also for example if the cars have for example solar panels for example on their roofs and/or their sides and/or even for example preferably transparent solar panels for example on at least some or parts of the car windows (for example based on covering the sides and/or roof and/or windows with some transparent chemicals) and can therefore be also for example preferably be recharged automatically during daylight hours while in the sun. Preferably the above described sensing and/or communication and/or automatic adjustment of the speed or amperage of recharge can be done for example by the computer in the car's own part of the recharge unit and/or for example by the car's general purpose computer and/or for example by the computer in the public recharger or recharge post, and/or for example some of the functions are done by the car computer or car's own recharger computer and some by the computer of the preferably public recharger. Another possible variation is that the recharger can preferably for example take into account also the electrical 24/12/08 Yaron Mayer & Haim Gadassi 32/304 prices according for example to day hours (for example by using its own database) and can preferably automatically for example start the recharge or for example increase the recharge speed mainly at the cheaper night hours so that preferably the user does not have to remember or worry about the optimal hours manually and/or for example the computer can get this information directly by connecting for example to information provided automatically for example through the Internet or for example through the power station, and/or for example such public rechargers or recharge posts can for example receive direct commands for example from the electrical company and/or for example the service provider preferably for example by information transferred preferably over the electric wires themselves, so that for example this way the electric company and/or the service provider can for example better control the division of power between various rechargers or recharge posts or areas in a more efficient way. Another possible variation is that preferably such public rechargers or recharge posts are made available also in many parking lots and/or for example in railway stations parking lots where people can park their car and continue by trains and/or for example on trains in which the user can board special coaches with their car, since typically modem trains run already on electricity and therefore there is already an existing electrical infrastructure at the railway which can preferably be converted also for recharging users' electric cars.
Another possible variation is that preferably the for example preferably public charger, which preferably has anyway at least one coil for flattening the pulses of the PWM that typically is needed for controlling the recharge speed and/or amperages, preferably has also a second coil and thus preferably contains a transformer which preferably increases the voltage to for example preferably volts or other desired high voltage for the more efficient recharge even for example at the home or office parking lot. Another possible variation is that preferably these preferably public rechargers or recharge posts for example in the building's parking lot preferably also communicate with a similar controller and/or sensor for example for the entire building, which preferably can behave similarly like the possible individual apartment's sensor or controller described above and/or preferably also the preferably public rechargers or recharge posts can preferably communicate with each other, so that this controller preferably measures automatically the amperage of the entire building and preferably communicates this automatically to the preferably public controllers, so that they can preferably automatically adjust themselves preferably to an optimal recharge rate possible without risking for example the building fuse or the neighborhood fuse jumping, and/or this is done automatically for example between more than one building and/or between street rechargers so that preferably the controllers of multiple buildings and/or for example a similar controller and/or sensor for example instead or in addition in the neighborhood or street's switchboard measures for exainple the general amperage in the street or neighborhood and this information is preferably automatically shared between the public controllers of the relevant nearby buildings public rechargers or recharge posts and/or street public rechargers or recharge posts and/or these rechargers also communicate with each other and thus preferably for example the entire or local neighborhood or street area which is connected to the relevant neighborhood or street switchboard can preferably automatically regulate their recharge speed to work preferably at an optimal recharge speed without endangering the fuse of the street or neighborhood fuse jumping. Another problem is that for example in normal 24/12/08 Yaron Mayer & Haim Gadassi 33/304 home of office switchboards eventhough there can be many fuses for individual rooms or sockets, typically there is only one residual current fuse, so that for example malfunctions in which the current overflows to the grounding cause the fuse of the entire apartment or office to jump. So preferably this is improved so that for example the home or office's main switchboard is improved so that it contains for example in advance (preferably through mass production) a hierarchical routing so that for example there is the appropriate wiring and place for adding for example a residual current fuse for example for each of N rooms or other grouping or branches of devices (so that for example different size pre-designed switchboards are available according to the maximum number of desired residual current fuses), so that for example at least each room or group is insulated from the others and does not cause the main fuse to jump even for example in case of overflow to the grounding. Another possible variation is that for example the fuses are improved so that there are available preferably cheap combined fuses which for example preferably cost for example $15-20 or less or for example only a few dollars more than a nonnal fuse and preferably function both as a normal fuse and as a residual current fuse, for example by using the same box and switch for both devices and including the coils and magnets and/or other components for each of the two devices in the same box. Similarly preferably the switchboard contains more than one smart meter or for example a smart meter or meters that can monitor separately more than one room, so that preferably the user can see independently the electricity usage for example on a room basis or for example even per socket or group of sockets.
Another possible variation is that the user can also be shown automatically for example how much electricity each device or for example each type of device is consuming - for example by improving electrical devices to contain for example special chips which can for example automatically communicate with the smart meter or meters and can for example send them an Id or code or for example other fingerprint that indicates their type and/or for example more specific identification details (such as for example also manufacturer and/or model) for example over the power lines and/or for example by using smart sockets in which the user can for example indicate the type of device which he/she plugs in to it for example from a menu or for example by moving a dial and then the sockets for example communicates this information. Preferably the user can see the relevant display for example on an LCD display on the smart meters or on the switchboard, or for example through the Internet on the electric company's web site preferably in real time (since preferably the smart meter automatically updates the main computer of the electric company and receives orders from them) and for example on the web site the user can preferably see for example additional data such as for example statistics and/or graphs of the change in usage over time for example for the total apartment and/or for example on a room by room basis and/or for example based on device types and/or for example for individual devices, and/or preferably the web site can display also for example similar statistics for example about other apartments or buildings for example in the area, such as for example the average consumption across other apartments for example in the building or for example in the street or for example in the neighborhood or for example in the town or for example in the country (these are preferably averages without identifying details of the specific apartments) so that the users can also see for example how much energy they are using compared to other similar reference points. Another possible 24/12/08 Yaron Mayer & Haim Gadassi 34/304 variation is that when recharging the electric cars, the rechargers or recharge posts and/or for example one or more central computers (for example in the electrical grid service and/or for example in the specific service provider to which the user subscribes or for example connects once in a while even without a subscription) preferably take into account also for example car-specific and/or user-specific parameters, for example in order to optimize the recharging priorities, so that for example at least in areas and/or times where the concurrent recharging capacity is limited, for example in crowded work areas for example at least in the main work hours and/or electricity demand peak hours or for example in crowded neighborhoods for example when recharging at night, preferably the rechargers or recharge posts and/or said computers can decide for example automatically which priorities to give to different cars - for example based on the state of their batteries (so that for example cars in which the battery is more empty or for example is almost completely empty preferably get automatically higher recharge priority than for example cars in which the battery is less empty or for example is almost completely full) and/or for example also based on additional parameters and/or heuristics and/or statistics and/or for example automatic repeated identification of cars based for example on a unique preferably digital ID number, so that for example the system can take into account also various regular and/or historical car-specific parameters and/or patterns and/or statistics, such as for example typical arrival and departure times, typical distances traveled, etc., so that for example a car that is regularly parked for example in the work space for example between 9am to 5pm for example can get lower recharge priority than for example a car that typically leaves at 2pm, since the car that leaves earlier needs the recharge earlier (so for example the car that leaves at 5 preferably will still get the energy that it needs, if it needs any daytime recharge, but it can be recharged more flexibly during this time for example after taking care of the more urgent recharges first), and/or for example a car that typically travels a longer distance each day for example between home and work for example gets higher recharge priority than a car that travels for example considerably shorter distances, and/or for example a car which typically leaves for example for work for example earlier gets by default higher recharge priority at night than a car that typically leaves the home area later. In other words, as explained also elsewhere in this application, preferably the recharge priorities are preferably applied both preferably globally for example over an entire country or state or electric supplier network (or for example even across countries which exchange electricity, such as for example in Europe) and preferably also locally within smaller areas such as for example cities and/or neighborhoods and/or streets, etc., since this is needed also within smaller areas for example to prevent overload for example on local high power transformers and/or for example fuses.
(Another possible variation is that for example at least temporarily for example at least in some areas where there are cars or recharge posts which enable charging the electric cars without accepting direct commands for example from the main computers of the service provider and/or the electric company, preferably for example the electric company and/or the service provider can also for example control overloads and/or activate priority policies for example by automatically disconnecting recharge posts for example individually if possible or for example based on groups, such as for example the recharge posts of an entire street or neighborhood, so preferably they work when they can without overloading their area and they are preferably time 24/12/08 Yaron Mayer & Haim Gadassi 35/304 shifted as needed so at to prevent overload also across areas). As explained above these statistics and/or calculations can be for example calculated automatically by the service provider's computers, and/or for example at least some of them can be automatically generated by the car's computer and for example communicated automatically to the recharger or recharge post when connecting to it and/or for example directly to the main computers of the service provider for example through cellular or other wireless communication - which can be for example more processed data, or even for example automatic requested recharge times based on the statistics, although that is less preferable since the service provider's computers have a bigger picture and can enforce more standard rules. However these statistics preferably do not include identifying or for example keeping track of for example the specific destinations or locations to which the car travels but preferably only for example the distances or for example more generalized patterns, in order to prevent privacy issues. The data communication between the car and the recharger or recharge post can be for example by transferring data over the power wires, but more preferably the plug-in cable contains also a separate data cable (isolated of course from the power wires but preferably within the same external envelope of the cable, so that for example the power wires are covered with a metal mesh to block interference and the data cable is outside this mesh and there is for example an additional for example plastic envelope around all of this), and so preferably the plug and the socket contain apart from the power connectors also a connector or connectors for the data link, and preferably the plug and sockets are shaped in a way that the plug can be inserted only when oriented properly (this means that preferably the data connector or connectors are in the same socket in which the power connectors are, or for example the socket is divided for example into separate sections or for example two physically coupled sockets, for example with a big circle or other shape for the power connectors and for example a smaller extension of the socket into the shape of a smaller circle or other shape for the data connector).
Another possible variation is that data link can even be for example based on optic fiber in order to further reduce possible interferences from the power wires.
Another possible variation is that the communication is for example wirelessly, for example through Bluetooth or UWB or for example Wimax, as explained also elsewhere in this application, but in this case preferably the correct car and the correct recharger or recharge post can preferably identify each other in a way that prevents confusion for example with the next nearby car or next nearby recharger or recharge post, which means that preferably at least some data is exchanged preferably at least initially preferably digitally for example through the cable connection (preferably with the unique IDs of the car and of the recharger or recharge post), or for example the car and/or the recharger or recharge post carry for example some optical digital code or other physical code which can be identified based on proximity, in order to confirm the correct match, but that is more problematic and less preferable.
Another possible variation is that for example the car and the recharger or recharge post can make sure they are talking wirelessly to the correct recharger or recharge post or car for example by the car's computer requesting the recharger or recharge post for example to make a certain signal for example by creating a certain temporary pulse or fluctuation or other change for example in the power or voltage, or vice versa, or such fluctuations are for example automatically used when first connecting in order to transfer the correct IDs to each other.

24/12/08 Yaron Mayer & Haim Gadassi 36/304 As explained above, preferably the above described sensing and/or communication and/or automatic adjustment of the speed or amperage or power consumption of the recharge can be done for example by the computer in the car's own part of the recharge unit and/or for example by the car's general purpose computer and/or for example by the computer in the public recharger, and/or for example some of the functions are done by the car computer or car's own recharger and some by the computer of the preferably public recharger or recharge post.
The advantage of keeping the recharger circuitry in the car are that this way the car can also be recharged for example from normal electric sockets, for example in the user's garage or home, for example if the user lives in a villa, and in fact this is the standard in nonnal prior art electric vehicles, except that prior art electric cars do not have a recharger which can vary the recharge speed or current or power consumption dynamically for example according to communication and instructions which it receives for example from the electric company or the service provider. In addition, many people live in apartment buildings without private parking and thus would have to recharge their car even at night in the street and/or sometime also have to recharge in parking places for example at work, so the public recharge posts are needed anyway on streets and parking places, and even people who live in an apartment building with a private parking lot might still need these posts because it is illegal to lower cables from the windows, although there can be for example sockets or private recharging posts that are connected for example directly to the electricity room for example at the basement or bottom floor of the building, as explained elsewhere in this application. Another problem is that even if the car's internal recharger receives instructions from the public recharge post for example when to start or stop or for example to increase or reduce its recharge speed or current or power, some hackers might for example rig the car's computer or the recharger to pretend to follow the instructions but in fact for example give itself higher priority. So preferably for example public recharge posts which interact with a car that is using its own internal recharger preferably automatically request the car's internal recharger to report how much current or energy it used (typically the recharger and/or the battery has to calculate this anyway during the recharging process so this information is readily available), and/or preferably also check for example the actual amperage and/or power that passes to the car and thus can for example preferably instantly fmd out for example if the car's recharger is not following the instructions correctly (for example by fmding that the amperage or energy measured by the recharge post substantially exceeds the energy that should have been used according to the instructions or the energy usage as reported by the car's recharger and/or for example that the energy usage reported by the car's recharger substantially exceeds the energy that should have been used according to the instructions), for example due to malfunctioning or due to tempering, and can in that case preferably for example automatically send an alert for example to the main computers of the service provider and/or of the electric company and/or for example automatically refuse to give further service to that car until the issue is checked and/or for example issue a warning to the car's driver (and/or for example the car reports this directly to the service provider for example through cellular or other wireless communication while the recharger preferably also reports its own measurements preferably at the same time). (This automatic measurement of the actual power consumption is preferably used anyway also for example for 24/12/08 Yaron Mayer & Haim Gadassi 37/304 calculating the actual charge for example in money or for example credit point or debit point, since for example even if the car's internal recharger has received instructions that allow it for example high power consumption, it might still for example use less for example depending on the state of the batteries). The measuring of amperage is preferably done for example by using a transformer with an appropriate circuitry and/or chips to measure the amperage data from it (for example by using induction coils around the electrical wires), and/or for example hall effect sensor or sensors and/or for example by shunt resistor and/or for example other sensors that measure the electromagnetic filed, or even cheaper meters which give an estimate which can have for example an error range of 1-5% or other reasonable number, so that preferably the recharge post in this case preferably issues a warning for example only if the deviation (for example of taking more power than allowed by the instructions) is bigger or substantially bigger than its typical or maximum measurement error (this deviation -can be calculated for example for any point in time that more power than allowed by the last instructions is used, for example in case the instructions limit for example the allowed peaks but is preferably based on some average over time - such as for example a few minutes or more, since for example the recharger might need to use cycles of more or less power based on the state of the batteries and/or the recharge pattern, and preferably the instructions limit for example the average power consumption for example over preferably small time unit, such as for example the average power consumption for example per minute or a few minutes or other reasonable time frame, and/or for example the deviation is calculated for example by the total or average recharge speed for example compared to the allowed speed or for example compared to an allowed average in a period determined in the instructions). Another possible variation is that for example the electric company and/or the service provider for example relies more on the amperage or power reported by the car's internal recharger, but for example each group of rechargers (for example 5 or 10 or 50 or other reasonable number) has for example an amperage or power meter, so that for example based on the repeated identification of the individual cars and the individual recharge post, for example cheating or malfunction can also be detected statistically based on the group meter for example after a number of rechargings.
Another possible variation is that for example only a certain sample of recharge posts contains the meters (for example 1 in 10 or 1 in 20 or 1 in 50 or other reasonable number), preferably in a way that there is no external indication if the recharge post contains a meter or not, but that is still problematic, since for example hackers might exchange information about "safe" or "unsafe" recharge posts for example based on trial and error. So if such sampling is used, preferably the location of the meters is changed periodically, for example by using the preferable modular preferably underground interface in order to switch between recharge posts, or for example by having an empty compartment within the recharge post into which the meter can be inserted or removed in a modular fashion, or for example by using preferably underground multiplexers which enable for example to route the meters to different recharge posts, for example by remote command from the service provider's main computers and/or for example by changing something for example in a street switchboard. Another possible variation is that preferably the communication between the car and the service provider is preferably done for example by encryption which uses automatically as keys for example also data from 24/12/08 Yaron Mayer & Haim Gadassi 38/304 internal devices that are integrated in the car, such as for example the engine or other parts, and is preferably embedded in the internal hardware of the car, such. as for example in ASIC chips, so that for example in order to forge a message the hacker would have to know also these encryption keys. Anyway, the point is that if the car is recharged by an internal recharger, preferably the car's recharger has to report the amount of power it used for example from the time of connecting the recharge post until disconnecting, for example to the recharge post or directly to the electric company or service provider, and preferably the service provider has at least some means of checking if there are substantial deviations between this report and the actual amperage used, as explained above, and preferably the monetary charge and/or for example credit points or debit points are preferably based directly on the actual energy taken by the recharger, as explained elsewhere in this application. The above variations are much'better than Shai Agassi's suggested model of charging the car only based on mileage, since unless the amount of energy used by the recharger is reported and taken into account and unless the report is preferably related directly to the recharge session from a specific recharge post it can be much harder to verify, and since the mileage might also be related to many other things apart from the actual amount of recharge energy, such as for example if the car is going uphill or downhill or for example in a plane, if the driver enables using automatic Neutral or similar mode for example when driving downhill (as explained elsewhere in this application), and for example if the driver uses for example the recommended top speed of for example 80-90 Km/H, or for example drives in a highway much faster, such as for example 120Km/H, which is much more wasteful due to air resistance, as explained elsewhere in this application. So paying only according to mileage (for example in money and/or credit point or debit points) is bad practice because it can encourage people to drive faster in a wasteful manner if they pay only according to mileage instead of according to the actual recharge energy. In addition, in a charge scheme based on mileage the service provider would have to deduct for example mileage which stems for example from recharging for example at home for example directly from the electric company or for example energy that is for example from solar panels for example on the roof of the car or for example other private renewable sources, such as for example a private wind turbine on the user's house, which would complicate things and would have to rely also on reports about charging through other sources. So, as explained above, preferably in case of charging at least partially by mileage and/or for example by mileage instead of by energy, preferably this additional data about other ways of recharging is preferably taken into account, and in addition preferably the service provider also gets for example from the car's computer for example periodically automatic reports such as for example various statistics about the traveling speeds used and/or for example about the general fuel-per mileage efficiency, and/or for example various statistics and/or additional parameters about the driver's behavior, so that for example drivers that drive in more wasteful ways or for example beyond a certain wastefulness threshold are preferably warned and/or charged extra even for example if the main charge is according to mileage, and/or for example there is a different rate of charge for different ranges of speed (so that for example until 80Km/H
there is one rate, for example between 80-110 there is another rate, and for example above 110 there is another are, or for example other values and/or divisions) and/or for example the rate changes continuously according to speed for example based on 24/12/08 Yaron Mayer & Haim Gadassi 39/304 some fonnula. Another possible variation is that if the user is for example in a monthly subscription plan with a service provider (when the service provider is other than the electric company) for example with a certain pre-paid amount of energy but for example also recharges the electric car for example directly from an electric company socket, for example at home, preferably at least as one of the options and/or for example as long as the quota of free or covered energy has not been reached, preferably the service provider has automatic coordination with the electric company, so that for example even when recharging the car directly from an electric company socket, preferably the charge automatically goes through the service provider, so that the service provider pays the electric company (preferably with the available reductions that it has through large scale deals with the electric company) and calculates this like a normal recharge through the service provider's recharge posts, so that for example the user has to actually pay only after exceeding the covered monthly quota. Another possible variation is that for example when connecting to a normal electric company socket the car's computer (preferably based on automatically choosing the cheapest option) or for example the user can for example choose each time or for example on an ongoing basis. (for example until changing the choice) for example if to pay directly to the electric company or to pay through the service provider (so that for example the user or the computer will choose to pay through the service provider for example if this is still below the covered for example monthly quota and/or for example if the service provider's rates even after commission are still lower than when paying directly to the electric company, for example due to the large scale reductions that the service provider is able to get). However, as explained elsewhere in this application, even when the user connects the car's recharge cable for example to a normal electric socket, preferably the car's computer and/or recharger and/or smart interface preferably still has to connect automatically for example through cellular or other wireless communication with the main computers of the service provider and/or of the electric company and work with their instructions and/or priority management, so that preferably the service provider runs the recharging of these cars for example directly or for example through the main computers of the electric company, or for example the electric company gets preferably regular or constant updates about the car priorities and/or other relevant data and/or parameters from the service provider and can thus for example implement the instructions to these rechargers also directly, and/or for example the electric company can also for example implement the relevant car priorities or policies for example by setting its own policies, but in that case preferably there are clear rules of coordination and/or preferably immediate updates between recharging run by the electric company and recharging run by the service provider, since otherwise there could be various conflicts.
Similarly, preferably if more than one service provider is allowed to run electric car recharging for example in the same or near areas or areas which get energy from the same electric company, preferably similar coordination and/or preferably instant updates are required, so that for example conflicts are avoided and/or for example clear rules prevent for example situations of overload or for example situations where one service provider takes too much power at a certain time and thus prevents the other service provider from operating in an optimal or reasonable manner, and/or for example one service provider offering higher priorities than are justified for example in order to appear more attractive to clients. In addition, preferably in order 24/12/08 Yaron Mayer & Haim Gadassi 40/304 to prevent monopolistic behavior, preferably at least if there is only one service provider in the relevant area or state or country and/or for example if there is more than one service provider, preferably the government and/or the electric company requires the service provider to comply with at least certain price regulations, so that for example the prices or rates charged by the service provider at least for the electricity preferably have to be authorized for example by government authorities (for example like electric company rates) and/or for example have to comply with certain rules, so that for example the rates at least for the electricity itself preferably have to be cheaper or substantially cheaper for example compared to the rates normally charged by the electric company for example for the same amount of energy for example when normally charging devices other than electric cars for example on average or for example at the same hours (since the automatic priority management of electric car recharging can be much more efficient than normal electricity usage), or for example at least if the user for example recharges through a normal socket of the electric company and/or chooses to pay through the electric company, and/or for example the service provider is required to allow users that don't want to use a monthly subscription and/or for example own their own battery to pay just for the electricity and/or other services according to the allowed rates and/or rules, and/or for example if the user works with the service provider for example based on a for example monthly subscription, preferably the service provider lists or has to list separately the charges for the energy part of the monthly charges for example in service contracts and/or in for example monthly bills (or other period), and/or for example the service provider preferably reports or has to report to the user also the total amount of electricity which the user received for example through the month (or other period) for example through direct charging or through battery swap (preferably the service provider reports the data for these two sources for example together and/or also separately), which can also be good for the service provide since it preferably increases transparency and lets users see that they are getting a good and fair deal, especially for example if the service provider has invested also in setting up the relevant infrastructures or for example if a certain service provider is paying for example another service provider or for example the electric company or the government for example for using the relevant infrastructures or some of them. Preferably the service provider lists separately for example on the monthly bill (or other period) for example how much the user paid for the car (if bought for example through service agreement from the service provider), how much for the battery (if owned by the service provider), and how much for the electricity, and/or preferably also how much for other services, such as for example for returning the investment for the infrastructure (preferably at least for example the recharge posts and battery swap stations), maintenance, parking management service fee and/or for example the parking payments transferred to the municipal authorities (for example for users who choose to pay parking through the service provider, as explained elsewhere in this application), etc. Preferably for example on the service provider's web site the user can preferably for example also view for example other periods (for example by choosing a period between two selected dates) and/or for example back bills and/or for example the expected near bill, and/or for example general statistics (preferably without any identifying details) for example about how much other users are typically paying, for example based on location (such as for example a specific town) and/or type of location (such as for 24/12/08 Yaron Mayer & Haim Gadassi 41/304 example living in a large city or in a rural area) and/or type of car and/or amount of miles or kilometers driven for example each month and/or average driving speed and/or chosen subscription plan, and/or other parameters, for example in general or for example for specific chosen period. However, since even users who bough a car with the battery will want or need to use also the battery swap stations at least once in a while, preferably if the car complies with the supported standards of the battery swap stations and/or can be adapted to that, preferably the service providers offers such users a certain credit for their existing battery and/or a certain charge if the car needs for example some additional installation to enable compatible battery swap, so that the user can enjoy the full service. Another possible variation is that for example in some apartment buildings there are recharge posts in the parking lot which for example draw their power for example from the common building's electricity room but preferably when using them the user pays directly to the electric company or through the service provider and then the electric company automatically deducts this from the building's common electricity bill.
Preferably this method can be used for example at least as a temporary solution and/or at least for example for installing recharge posts for example for people who bought or for example plan to buy soon an electric car and for example there is no infrastructure for electric cars yet in their area, since this way the service provider or the electric company do not have to lay new underground wires for example to the relevant area except for example a short underground or above ground cable for example from the building's electricity room for example to the parking lot or for example to one or more spots on the street near the house preferably at least if the recharge post can be used for example by more than one person in the building or in the street, and/or for example the coupling of recharge posts for example to existing street light poles or to electric power poles as explained elsewhere in this application can be used for example as a temporary arrangement for example for providing recharge posts for people who need it before a more full infrastructure is laid in their area, so that for example after digging new wires underground the same for example temporary recharge posts can be for example rerouted to get their energy now from the new underground cables, and/or for example the service provider or the electric company preferably install the underground wiring for example from the nearest street (or for example neighborhood) switchboard or transformer to the location of the needed recharge post preferably with additional underground modular interfaces or stubs along the way as explained elsewhere in this application, so that for example when adding additional recharge posts along that line the service provider only has to dig or open the cover over preferably small holes and connect the additional recharge posts, and/or for example areas where there are one or more early adopters preferably get the infrastructure installed before other areas, preferably based also on additional considerations, such as for example the general plans for that area or priority or centrality of the area (the above two variations mean that preferably the service provider does not work differently than normal infrastructure installation procedures, except that preferably the early adopters and/or their areas can get the infrastructure or its skeleton before other areas, which has also the advantage that this way parts of the infrastructure can be tested in advance for example in various areas for example by at least some of the early adopters for example a long time before the full infrastructure is complete, so that for example various problems can be solved or improvements can be made for example based on installation problems 24/12/08 Yaron Mayer & Haim Gadassi 42/304 and/or user feedback preferably already after installing only a small percent of the full infrastructure). Preferably in order to speed up such special need-based installation of recharge posts and/or local infrastructures or their skeletons, preferably for example users who already bought or ordered the car or for example signed up for one of the relevant subscription plans can get the recharge posts installed. preferably for free and preferably within a short time from the time of requesting the installation - such as for example within a few days or up to a week or other reasonable period, and/or for example users who want to order the installation in advance before ordering the car or before signing up for the subscription preferably have to pay some installation fee, and then when they buy the car or sign up for the subscription they can preferably get back for example a full or partial refund for the installation cost. Similarly, preferably for example if there are free recharge sockets offered for example in certain places for example by the municipality or for example by certain resorts such as for example some malls or for example some hotels or for example some restaurants or for example some big shops or networks, etc., preferably such sockets for example have a special unique Id and/or for example some other special code or special marker or hardware which is for example pre-listed for example in a database for example in the main computers of the electric company and/or of the service provider and for example according to these Ids or codes or other special markers or hardware the service provider and/or the electric company know not to charge the user or for example charge the municipality or the company that offers the socket instead, and preferably if for example such interface is stolen the owner can for example report its special Id or code and have that Id or code for example revoked. This is preferably done regardless of whether the communication with the main computers is through the outlet or for example through direct communication with the car's computer, since if the car computer communicates directly with the main computers it preferably also sends the unique Id of the outlet to which it connected or for example at least its exact location, as explained elsewhere in this application. In addition, preferably when connecting to such recharge posts preferably the recharge post or the service provider's main computer preferably automatically send a signal or message to the car's computer that indicates that this is a free of charge recharge post and the car's computer preferably automatically displays this information to the user.
Another possible variation is that for example the service provider uses at least sometimes also the reports by the car about the mileage, but only for example as additional evidence for example in case of a mismatch and debate about the amount of energy reported for example not fitting the amount of energy measured. Another possible variation is that preferably similarly the smart recharger network or electric network preferably has also for example one or more higher hierarchy levels of for example gateways which for example measure also directly the current or power passed through them and can compare it for example with the current or power reported for example by individual rechargers or other devices and can for example issue an automatic alert if for example there is a significant mismatch between the power consumption reported for example by various rechargers and the actual amount it measures itself. In addition, keeping an internal recharger circuitry in the car has the disadvantage of substantially increasing the car's cost (and also increases the weight and takes up room in the car) compared to an electric car that only relies on external recharging of the recharge post. On the other hand, keeping the recharger inside the 24/12/08 Yaron Mayer & Haim Gadassi 43/304 electric cars has other advantages - for example because it enables building a much cheaper infrastructure, since the recharge posts do not have to contain the recharger circuitry and the heat dissipation unit, and this also has the advantage that if for example in the near future new types of batteries or for example super capacitors or for example other fast electricity storing devices become available in cars which might for example need a significantly different type of recharge circuits, or for example different types of recharger circuits are needed for different types of cars which are available at the same time, this saves the service provider the need to change the circuitry in recharge posts or add circuitry to them or have to deal with statistical distribution of rechargers for different types of devices, and in addition it enables for example to built cheaply more recharge posts than the number of cars.
Another possible variation is that for example public rechargers or recharge posts preferably have software and/or firmware elements which can preferably be updated easily, preferably for example through remote preferably encrypted downloads for example directly from the main computers of the service provider, so that for example programs for recharging new types of batteries or for example super capacitors or other new storage means can preferably be updated automatically from a central place preferably without additional costs to the service provider.
Another possible variation is that if an internal recharger is used in the car and for example a new type of batteries is introduced by the service provider, preferably a similar relevant automatic software and/or firmware update for example for the recharger and/or for the car's computer can also be automatically downloaded for example from the service provider to the car's recharger and/or to the car's computer, for example through the direct cellular or other wireless communication between the car and the service provider's main computers or for example when connecting with the battery swap station (for example through wireless communication or through a data link) or for example when connecting for example through the data link to a recharge post. So as explained above, if for example the electric car can also be recharged directly for example from a normal electric socket, preferably the recharger unit within the car is also able to communicate and receive instructions for example from the electric company and/or the service provider, for example through transferring data over the power lines and/or for example through Wimax or Wi-Fi or UWB or cellular or other wireless communication, for example by using a built in cell phone or cellular modem in the recharger or for example in the car's computer.
On the other hand if for example the car has an internal recharger but the car's recharger or for example the car's computer does not have such communication abilities (i.e., for example the user has a prior art electric car, without the communication abilities and/or without a recharger which can increase or reduce its recharge speed or current or power consumption according to instructions), then preferably the user can for example use an additional intermediary unit or interface for example between the cable's plug and the socket, so that for example this unit contains also the cellular or other type of communication unit and preferably a unique ID of the user and/or of the car which is preferably communicated automatically preferably with encryption, so that for example both the cellular number of the unit and the unique id can be taken into account for identification (using the cellular number alone for identification is not preferable since hackers might for example forge it), and preferably the car's normal cable is replaced by a cable that contains also a data link, or for example the car's power cable is coupled 24/12/08 Yaron Mayer & Haim Gadassi 44/304 with an external additional data cable, so that for example the interface unit preferably contains on the wall side for example the normal for example 3 pins for normal electric sockets and on the other side (that connects with the car cable's plug) preferably has an electric socket together with an additional data link, which can be for example another hole or holes or for example one or more pins which fit in a hole in the plug (preferably the data link is based on two balanced wires, which can be cheaper and less sensitive to stress than an optic fiber and still protected from disturbances for example from the power wires), and the data link can for example connect to the car's computer or recharger, or for example the interface unit contains its own circuitry for example for automatically opening or closing the electric connection or for example controlling the amount of current and/or power and/or for example increasing or reducing the recharge speed or average current or power for example by creating a desired sequence of closing and opening the connection multiple times for example every few seconds so minutes or other reasonable period in order to create statistically an effect similar to reducing or increasing the current or power or reducing or increasing the recharge speed and/or for example by changing the voltage and/or other electronic means (or for example the user can by for example a cellular or other wireless communication and/or control unit for and example add it to the car's computer or recharger for example in a modular fashion). This is extremely important since if many users use normal prior art electric vehicles which do not communicate with the electric company or with the service provider, then when many such people recharge at the same time the network could overload and crash. So preferably for such prior art electric cars the electric company encourages people to buy the above described or similar interface unit, for example by using the unit also as a smart electrical meter so that preferably users can benefit for example from preferably significantly reduced recharge rates for example at night preferably only by using this interface (and preferably when high amperage that is typical for recharging electric cars is used, preferably even if the user has already also another smart electric meter which can determine the time of day, preferably the electric company gives even such users only a partial reduction if they have are not using the interface unit), and preferably this interface unit costs approximately the same or less than a normal smart meter which can measure if the electricity is used for example at night or during the day, and preferably these rules apply for example also if this unit is for example instead built in for example in special sockets or for example private recharge post for example in the building's parking lot. Preferably the interface unit functions as a smart meter for example by sending to the electric company automatically the data about the amount of electricity or power used for recharging the electric car and the times of using it and so for example the electric company can automatically cross reference this data with the user's actual electricity usage for example according to the normal meter and can thus automatically give the user the reduction for example when calculating for example the final monthly bill. Preferably this unit also contains for example an internal buffer and for example waits for acknowledgements for its messages so that for example if temporarily there is no cellular reception it can for example keep the data and transmit it later when the connection becomes available again. Another possible variation is that this interface can also function as a smart meter also for reporting the electric usage times also for the rest of the apartment or for other devices in it or at least for some other devices 24/12/08 Yamn Mayer & Haim Gadassi 45/304 in it, for example by communicating with an additional element which is installed for example in the central electric switchboard at the apartment or for example in the relevant switchboard of the apartment for example in the electricity room for example at the bottom of the building (as explained also elsewhere in this application) so that for example the smart interface reports to the electric company at the same time not only its own power consumption but also the power consumption of the rest of the apartment at the same time, or for example it automatically logs this data internally so that for example when the apartment's meter is checked once in a while the technician also collects for example the logged data from the smart interface unit, or for example the smart interface unit transfers this logged data automatically to the electric company for example one every month or for example other reasonable period.

But as explained above, if the car has its own internal recharger, preferably it is an improved recharger which can automatically increase or reduce its recharge speed or current or power according to instructions which it receives for example from the electric company's computers or from the service provider's computers, and preferably it communicates directly with these computers for example through cellular or other wireless communication as explained above, preferably even when connecting for example to a normal electric socket. In this case preferably the automatic communication from the car is preferably automatically used also for example by the electric company or by the service provider to give the user the automatic reduction for example at night time. This also means that preferably when electric cars which have their own internal recharger connect to the service provider's rechargers for example in the street or for example in parking lots, preferably public rechargers also have, preferably apart from preferably at least one socket for recharging electric cars that do not have their own recharger, preferably also for example one or more passive power transfer sockets for recharging electric cars that use their own recharger for recharging, and in this case for example the car's recharger can preferably for example communicate with the public recharge post for example by cellular or other wireless communication or for example by a direct additional data link, and/or for example after the user accesses the recharge post for example by passing for example a smart card or credit card or other device through an interface on the post and/or for example entering a password or secret code and/or for example by using a cable with a data link or by transferring for example at least the identification data over the power line, then preferably for example the car's internal recharger for example does not need to communicate with the public recharger or recharge post and can for example receive the instructions for example directly through the cellular communication for example directly from the electric company's computers and/or the service provider's computers (which means that for example in this case the cable and the plug can also be without the data link and for example the car's computer can also communicate the relevant statistics and/or relevant needs and/or other parameters for example directly to the main computers of the service provider and/or of the electric company for example through the cellular or other wireless communication). (Since the identification of the connection between a specific car and a specific recharge post can be done also by automatic data exchange at the moment of connection, as explained above and in other places in this application, the main advantage of using for example a smart 24/12/08 Yaron Mayer & Haim Gadassi 46/304 card or credit card or other device and/or password or secret code is making it harder for a thief to recharge a stolen car, however, as explained elsewhere in this application, another possible variation is that for example the car and/or specific batteries can be automatically blocked from accessing the network for example by the service provider's computers for example after the car is reported and preferably verified a stolen, and so for example the identification might also be simply based just exchanging IDs through the data link without a need for further actions).
Another possible variation is that for example the user's smart card or other device might for example be linked or limited for example to a single car or for example a group of cars (for example belonging to a family or a company, for example by defining this in the databases of the service provider), so that for example if the smart card or other device is stolen it cannot be used for example for recharging other cars. Another possible variation is that if is for example a prior art electric car which has an internal recharger without communication capabilities or ability to reduce or increase the recharge speed or current or power then preferably the user can use for example the same type of interface unit as can be used at home, or for example the additional alternative sockets at the recharge post contains such a unit built-in, or for example such an interface unit is also built-in for example within the private sockets for example in private parking places of buildings, since otherwise the interface unit might for example be stolen (so that preferably the built-in unit can also similarly control for example the recharge speed of even a dumb internal recharger of a car for example by lowering or increasing the amperage that canpass through and/or controlling a certain statistical pattern of closing and opening the connection, as explained above). Another possible variation is that for example when the connection is created preferably the interface unit becomes automatically mechanically locked until the recharge plan is finished as is preferably done also with normal recharging through the public rechargers or recharge posts, as explained also elsewhere in this application, and in addition preferably the user's.
plug that connects to the interface unit or for example to a recharge post socket which has such an interface unit built-in, is also preferably automatically mechanically locked while the recharge is going on. However, since after the recharge plan has completed preferably the lock is automatically released so that other users can recharge their cars, as explained elsewhere in this application, this means that preferably the interface unit is built into the recharge post preferably both in public rechargers or recharge posts and in private rechargers or recharge posts for example in the private parking lot, since otherwise the interface unit might for example be stolen after the lock is released. Another possible variation is that if the car's recharger has communication and speed change abilities then preferably its electric cable and preferably also its plug come in advance together also with a data link, like the cable of cars that are recharged directly by the recharger of the recharge post (as explained elsewhere in this application), and preferably such a cable can for example connect also normally to nonnal electric sockets but preferably contains for example apart from the normal for example 3 connector pins preferably for example also one or more holes for the data link, so that for example when connecting to the appropriate socket in the public recharge post preferably one or more pins in the recharge post's socket connect into this hole or holes for the data communication. Another possible variation is that for example the same socket in the public recharger can be used both for recharging cars which don't have an 24/12/08 Yaron Mayer & Haim Gadassi 47/304 internal recharger and for proving normal power links for a car with a recharger, so that for example after the data exchange the public recharge post can for example automatically switch into a different mode for example if it detects that the car has its own recharger and thus for example disconnects its own recharger circuitry and transfers for example the electric company's network's ac power on the power cable instead of for example the normal DC pulses from its recharger's circuitry.
However that is less preferable since it wastes the recharger's circuitry, since if separate additional sockets exist they can allow for example an additional car with its own recharger to recharge at the same time, for example in a parking lot where for example more than 2 cars can connect to the same recharge post (but on the other hand for example if in the street only up to 2 cars can connect to the same recharge post anyway, it does not matter if each of the two sockets can function as needed either as an active recharger or as a power connection, depending on the type of car that connects to it). However more preferably the socket for power interface for cars that recharge through their own recharger is preferably a physically and/or mechanically incompatible socket, so that users for example cannot plug by mistake for example a cable of a car which does not have its own recharger for example into a power transfer post which does not have it own external recharger circuitry.
Another possible variation is that for example a socket in the recharge post which can automatically change its function is built in a special way that allows both types of plugs to fit in but for example a socket for only one of the types has for example one or more additional pins or protrusions which don't allow the incorrect type of cable to fit in. On the other hand, preferably the additional alternative sockets for power transfer are preferably the same socket both for prior art electric cars which do not have a rechrager with communication abilities or speed or current change abilities and for cars which have a recharger with these abilities, and preferably the recharge post can identify automatically which of these types the car's recharger belongs to, for example by sensing if the plug of the car's cable contains the hole or holes for the data link and/or by trying to communicate with the car's recharger.
This means that preferably if for example the data link interface has for example one or more holes in the plug of the car's cable (which as explained above is a good way for enabling also connecting to a normal electric socket with the same plug), preferably for example the matching pin or pins in the recharge post's alternative socket are preferably automatically collapsible, for example with a spring, so that for example if the user's plug does not contain the hole or holes for the data link then the relevant pin or pin preferably automatically retract into the recharge post's socket. Another possible variation is that for example the authorities for example at least in some countries do not allow cars to connect to normal electric sockets without the smart interface which can communicate with the electric company's computers and/or the service provider's computers and control the recharge speed or power or at least can automatically close or open the connection, and so for example in order to import electric cars to that country preferably the manufacturer (or for example the importer) has to add the appropriate firmware and/or software and/or additional hardware for example to the recharger and/or to the car computer and/or other elements in order to enable these recharge speed or power change abilities and communication abilities (for example by adding an internal cellular phone to the car's computer or to the recharger) and/or replace the cable and plug with an appropriate cable and plug that contain the data link (in case this is desired or 24/12/08 Yaron Mayer & Haim Gadassi 48/304 required instead of or in addition to the cellular or other wireless communication), or for example at least the plug and/or the cable have to be changed so that they fit only into a special socket in the interface unit or in the relevant socket in the private or public recharge post, and/or for example the electric company or service provider gives for example a significant or extended reduction for example at night hours for example only to cars with such smart rechargers - which is preferably also substantially larger than the reduction that is received for example if the user has a prior art electric car which only uses the intermediary interface - because a recharger which can directly respond to instructions from the electric company or the service provider can work more efficiently than the power control which such an intermediary unit can supply. Another possible variation is that for example even a car that has its own recharger can for example also operate at least in one mode in which it is recharged by the public post's recharger, so that for example after receiving a certain command from the public recharger the car's computer or for example the car's internal recharger's processor can for example automatically disconnect the car's internal recharger and allow the public recharge post's recharger to recharge the batteries directly as if the car does not have an internal recharger. Another possibility is that for example if the car does not have this ability to disconnect the internal recharger of the power batteries upon command, preferably for example the importer or for example a service technician can for example preferably easily connect for example a bypass link which for example connects the batteries for example to the car's cable without going through the car's internal recharger or for example also replace the cable to an appropriate cable with the data link (for example if the car is a prior art electric car with a normal power cable without the data link), and/or for example add a manual switch which the user can use for example to switch between using the internal recharger for example when connecting to a normal electric socket or for example to a socket which contains the smart interface, and for example for using the external recharger for example when connecting to the recharge post, and in such case for example preferably the user gets a further reduction in recharge costs for example only if allowing the recharge post external recharger to charge the batteries. Another possible variation is that for example the car batteries can come with their own separate interface for example to the car's cable or for example together with the alternative cable which contains also the data link and for example with or without an internal recharger so that for example the type of batteries or for example of their envelope can determine for example if the car's internal recharger will be used or not, and so for example by inserting the appropriate batteries with their interface preferably the car's internal recharger can be for example disconnected anyway, or for example the batteries or their envelops can for example add an internal recharger to a car that comes without it. Another possible variation is that for example, since public rechargers or recharge posts which function only as interface without their own recharge circuitry are much cheaper, preferably the service provider can for example at least initially for example spread different types of recharge posts as needed at the time (preferably based on the types of electric cars statistics in that area at that time), so that for example some of them contain the recharger circuitry (but preferably also one or more additional alternative sockets for more passive power supply for cars that recharge through their own recharger as explained above, or for example with sockets that can change their function automatically as 24/12/08 Yaron Mayer & Haim Gadassi 49/304 explained above) and some posts contain only power supply or socket and preferably the user interface for example for passing for example the credit card or smart card or other device and/or typing a password or secret code, etc.), preferably based on the statistics of the number of electric cars with an internal recharger and the number of cars without an internal recharger, or for example if all the electric cars have a smart internal recharger, then for example the recharge posts can be for example divided just to posts that contain only the power supply or socket and preferably the user interface (for example 80%-90% or other reasonable ratio), and for example posts that contain fast rechargers, so that for example posts that contain the recharge circuitry are only or mainly fast rechargers which are used for fast recharging (i.e. for example enabling a full recharge for example in 1 hour or for example half hour or less or other reasonable time). Another possible variation is that for example there are for example at least some luxury cars that contain a fast internal recharger with sufficiently strong heat dissipation, and then for example the service provider provides for example also a certain spread of fast recharge posts which only contain for example the socket and preferably the user interface, but preferably enable for example preferably much higher amperage or power. But even in this case preferably the service provider provides also at least a certain percent of recharge posts which contain fast rechargers, since a certain percent of cars might need fast recharge for example each day (which might be the same cars or different cars, as explained elsewhere in this application) even if they don't have a high speed internal recharger, so having only passive recharge posts is less preferable since it would mean that only more expansive cars which have an internal fast recharger could achieve for example a full recharge for example in an hour or for example half hour or less. Preferably the fast rechargers are visually marked or designed in a way that is clearly visually different from normal recharges or recharge posts so that they can be easily identified even from a certain distance of for example a few meters or more, and they can be for example interspaced at certain intervals among normal rechargers or recharge posts (for example on the street) or for example concentrated in a fast-recharge area (for example in parking lots), and preferably the user can request the main computers (for example through the wireless communication with the car's computer, or for example the car computer can do it directly for example from its own internal database, which is preferably for example automatically updated periodically for example through the wireless link with the main computers or for example through the data-link when connecting to recharge posts) for example to direct him/her to the nearest preferably currently available normal recharge post or to the nearest preferably currently available fast recharger as needed and/or for example the computers do this at least some times automatically for example based on his/her needs and/or recharge priorities. Preferably if the user for example needs fast recharge for example beyond a certain for example monthly limit (or for example other period and/or criteria) preferably he/she can be for example charged extra or not charged extra for it and/or for example charged extra only by a certain extent or amount or rates for example based on his/her service plan (for example in money and/or credit or debit points), and/or for example if the user requests to use one of the fast rechargers for example even if his/her current needs and/or other relevant parameters do not justify it, preferably normal users for example have a certain for example monthly free quota also for this so that they can for example be charged extra if they exceed this quota and/or for example based on 24/12/08 Yaron Mayer & Haim Gadassi 50/304 their service plan, or for example the quotas and extra charges are the same regardless of needs justification (but this is less preferably since it can reduce the quality of service for users who do really need the fast rechargers), and/or for example the service provider preferably takes into account also for example the current needs and/or demands and/or availability for using the fast rechargers, so that for example if in a certain parking lot for example of a work area for example there are sufficient free fast rechargers, for example the service provider's main computers and/or the local recharge post's computer and/or for example a main computer in the area can for example decide for example at least on certain days and/or certain hours for example to allow recharging from the fast rechargers for example without extra charge and/or without losing credit points towards the quote or after the quote, and/or preferably when the user connects to a fast recharge post or for example requests to be directed to a fast recharger or for example sends a request or query about using it preferably the recharge post or for example the service provider's main computers preferably inform the user automatically for example if this is considered justified for example based on the user's current battery state and/or other relevant parameters and/or needs which determine car priorities, and/or preferably if this is within the free or covered quote and/or for example how much fast recharge is still available for example freely until the for example monthly quota is reached. Another possible variation is that similar rules can also used for example in case of excessive and/or unjustified use of for example swap stations, and preferably this also takes into account for example the amount of congestion for example in the swap station. Another possible variation is that for example there are no quotas but for example using fast rechargers and/or for example using swap stations automatically involves for example at least some extra charge (for example by money and/or credit or debit points), preferably for example while taking into account for example also the time of day and/or for example which day it is in the week and/or the current state of demand or congestion (since for example on weekends or holidays preferably the recharge costs are cheaper for example even in daytime or for example midday time or for example in midday there is for example more congestion in battery swap stations then for example in the evening or night), or for example using the swap stations at least when justified in fact involves receiving credit for example compared to recharging or fast recharging during daytime since this enables the service provider to charge at night and thus reduce the energy cost compared to a situation where a recharge is needed during daytime or peak hours. Another possible variation is that for example at least some cars are sold without the actual internal recharger installed but only for example with a ready space or one or more compartments in which a recharger and preferably also its heat dispersion unit can be inserted, or for example the battery or its envelope can include also the internal recharger unit and/or for example also the recharge cable or an interface to the car's cable, so that for example the type of battery installed determines also if the car contains an internal recharger or not.
Another possible variation is that for example the recharge post itself preferably contains for example a modular interface for example at the top and/or for example at the side so that for example the recharger circuitry and/or the heat dissipation unit and/or the relevant sockets can be for example preferably easily added to or removed from existing posts, thus converting for example active recharges into passive recharge posts or vice versa without having to swap the pole itself.

24/12/08 Yaron Mayer & Haim Gadassi 51/304 Preferably if cellular communication is used, preferably for example the cellular communication between the recharge post and the main computers or between the car and the main computers or for example between the car and the recharger is preferably done for example mainly through Internet Protocol communication and/or for example through the SMS network, since a large service provider and/or the electric company can use their size to get very cheap deals with the cellular companies. Of course, like in other places in this application, various combinations of the above and/or other variations can also be used.

If for example a high speed public recharger uses its own recharger circuitry to recharge the car, preferably even if it is connected for example to a 3-phase socket or interface in its own connection to the electric grid (i.e. a socket that uses 3 phases at the same time and typically requires 5 wires), preferably the cable that goes to the car still has for example only 2 or 3 wires preferably plus a data line, as explained elsewhere in this application, since the recharge is typically done with DC
pulses.
On the other hand, if the car can for example also connect to a 3-phase socket on the wall or for example in a public recharge post, this means that preferably for example the cable is still a 3-wire cable and for connecting to a 3-phase socket a preferably removable converter interface is used which makes the 3-phase socket appear as a normal socket, or for example this interface is internal within the recharge post so that even a 3-phase recharge post has sockets with only 3 power lines plus preferably the data lines, or for example the car uses a five-wire cable which ends for example with two separate plugs, one for use with normal sockets and one for use with 3-phase sockets, or for example the plug has 5 pins preferably plus the data connection and for example when connecting to a non 3-phase socket preferably for example the two extra pins for example automatically collapse into the plug for example with a spring, and/or for example a similar arrangement can be used for example if a 5-wire cable is connected to a socket in the car.

In addition, preferably each recharge post or for example each socket or connection in the public recharge post or recharger (preferably regardless of if it is an active or a passive recharger or socket, i.e. if it contains its own recharger circuitry) preferably comes with its own fuse and preferably also residual current device or for example these two types of fuses are combined into the same device, so that for example in case of a malfunction in any socket or connection (for example due to a short circuit in the cable or connection or for example due to a car hitting a recharge post) preferably it does not affect for example the other socket or sockets or cables or other connections on the same post or for example other nearby posts, and preferably for example at least each group of posts is protected by at least one spike-protection unit (so for example each such unit can protect for example a few dozen rechargers or recharge posts or other reasonable number), so that sudden large jumps in voltage or current preferably do not cause damage to important or expensive components, and preferably the system can automatically sense and report for example to the service provider's main computers for example if a recharge post or socket or cable or other connection or other element or elements in the recharge post malfunctions or for example a fuse has jumped - for example by sensing if there is voltage after the fuse (for example by two cheap resistors).
However, assuming that most recharge posts preferably contain just two sockets for 24/12/08 Yaron Mayer & Haim Gadassi 52/304 recharging one car before the recharge post and one car after it as explained elsewhere in this application and in order to save costs preferably each such recharge post has only one fuse and one residual current device (or combined into the same device as explained above) for both of its sockets. In addition, for example in case of a power outage preferably for example when power is restored preferably for example the main computers of the service provider or of the electric company can preferably automatically control the pattern and order of returning power to rechargers, for example by automatically closing or reopening gateways in various areas and/or for example by sending automatically commands to recharges (for example if the recharges are in the cars, thus receiving commands wirelessly, or for example to public rechargers or recharge posts, which preferably have at least one backup battery for keeping the communication and at preferably least some circuitry or processors open even when there is no electric power from the grid) for example to shut themselves off and not to start working again for example for a certain time period and/or for example until receiving a command to start working again, and preferably apart from consideration of quickly and safely restoring the power after the outage, preferably the computers also take into account the various car priorities when deciding on the order of restoring the power. So for example if the recharge post contains for example its own cellular communication unit, preferably the backup battery can be used both for keeping the minimal circuitry and/or the communications running - preferably for example both for receiving instructions during or when beginning to recover from a power outage and/or for reporting malfunction and/or jumping of fuses, or for example only one post in a group of posts has the for example cellular or for example other wireless communicator and for example its neighboring posts are connected to it through underground data cable as explained elsewhere in this application as one of the possible variations, and/or for example a single backup battery can be used for more then one post for example through their underground power connection or through an underground data cable which can also carry some power or for example through a separate small power cable which is used for example just for the backup power. Preferably the power from the backup battery can be used also for example for powering for example some LEDs with a special color or shape or some other visual indicator that can for example signal malfunction, so that for example users can know in advance which recharge posts are not operational, or for example posts that work properly for example have some green or other light or other visual indicator that shows this so that for example during a malfunction or after a fuse jumps the light is off so the lack of the normal light or other visual indicator becomes an automatic indicator of malfunction. Another possible variation is that for example if the recharge plan of some car has ended and/or for example if the paid-for parking time of that car is about to end or has ended, preferably the recharge post can for example flash with a special light (for example orange) or other visual indicator, which signifies that for example the cable can now be removed so that another car can use the socket or that for example the parking spot is about to become vacant, and preferably these visual indicators are conspicuous enough so that a passing-by driver can see them from within his/her car. Another possible variation is that if for example the user parks for example in a parking lot of a for example large mall and for example forgets to write down the floor number and/or column and/or row, and/or for example parks in a street and/or otherwise forgets where he/she parked 24/12/08 Yaron Mayer & Haim Gadassi 53/304 the car, the user can for example send for example through a cell phone for example an SMS or other communication for example to the car and/or for example to the service provider's computers so that for example the car computer can automatically report back to the user the car's position for example through GPS or through automatic locating by the nearby cellular company's cells or similar or other means, and/or for example if the car is connected to or a recharge post for example even if it is merely located near a recharge post (for example in its parking lot or for example in an adjacent or nearby parking lot or for example even at a distance of for example a few cars or more from the recharge post) preferably the car computer can for example communicate with the recharge post (for example through UWB or Bluetooth or other preferably short range wireless communication, which is for example preferably limited to 10 meters distance or less, or for example through cellular communication) or with the service provider's main computers and get for example the GPS coordinates or for example the floor, row and/or column and/or for example street name and/or number and/or similar or other location data.
and can preferably communicate it to the user (and/or for example the user can get the reply through the service provider's computers, since they preferably have both the unique id of the recharge post and of the car that is currently connected to it) - since such data is preferably entered anyway for each recharge post for example by the service provider, since it is needed for example also to enable for example service technicians to quickly find it - so that for example the service provider's main computers and preferably also the recharge post itself preferably have a database which associates the unique id of the recharge post (and preferably also for example of at least its near neighbors) with specific geographic parameters or similar location data, so that for example when installing recharge posts in the mall for example the installing technicians preferably enter into the recharge post's processor for example the floor, row and column, and for example the recharge post automatically reports this also to the main computers, which then keep this data also in their own database. Preferably the user can also see this information for example on the service provider's web site, so that apart from seeing for example how the recharge is progressing, as explained also elsewhere in this application, preferably the user can also see for example the street name and preferably also number in which the car is parking near a recharge pots and/or for example the columns and/or row and/or floor if the car is for example in an underground parking place, and preferably if the car is currently plugged-in and/or for example if the car is currently being recharged in practice or is for example in a waiting state or is for example currently giving back energy for example through the V2G services. Another possible variation is for example to add similar functionality for example to parking meters even when there are no recharge posts there, but this is more preferably done with recharge posts since they have a communication infrastructure which parking meters typically lack and since for example in parking places in malls there are typically no recharge meters, but there will soon be electric rechargers.
Another possible variation is that this is done for example by adding special dedicated devices for this for example every few parking places or for example at least for sub-areas of the mall's parking lot, so that said devices are programmed for example with the relevant coordinates and can for example communicate with the car and/or with the user for example through cellular or UWB or WiMax or other wireless communication. Another possible variation is that for example at least in parking 24/12/08 Yaron Mayer & Haim Gadassi 54/304 lots where there is more flexibility in the placement of cars than for example in a street, preferably if there is for example temporarily a shortage of recharge sockets and there is still room for one or more additional cars to park for example near a recharge post that has for example only two sockets or otherwise does not have enough sockets, preferably there are special mobile socket splitters which are preferably issued for example by the service provider and can be used for example for converting a single socket into two or more sockets, and preferably this extension socket multiplier can preferably for example be obtained freely or for example against some deposit, preferably directly from the service provider or for example from the parking lot manager, and can for example be installed by the user or for example by the parking lot manager. Preferably even if a car is for example in the process of recharging from the socket, preferably for example by entering a special code and/or for example by passing a part of the splitter which for example acts like a smart card for example through the smart card reader of the recharge post, preferably the recharge post can for example temporarily stop the recharge from that socket, and enable the user to insert the splitter and then reconnect the car that was in the process of recharging. In addition, for example to prevent abuse preferably the splitter can for example enable the new connecting car to recharge for example only if the car's who's recharge was interrupted is also reconnected on one of the multiplied sockets. In addition, the socket multiplier preferably contains a separate fuse (preferably including the residual current fuse) for each new socket, so as to keep again the recharging of each car independent from problems in other rechargers.

If for example the system also enables for example returning energy from electric cars to the grid for example in times of peak demand, as suggested in some articles, then preferably this is done either by adding circuitry and/or for example DC
to AC
converters to the rechargers (for example in the car or in the recharge posts) that enables them also to draw energy from the batteries preferably in the way needed by the electric companies, or for example this circuitry is built-in in the recharge posts and for example if the car has a recharger of its own then preferably the recharge post can issue a command which preferably causes the internal recharger to disconnect and/or otherwise enables the circuitry in the recharge post to access the batteries di.rectly. However preferably the circuitry for this is included in the car itself so that it can preferably be used also for example when connecting no normal electric sockets, for example by using also an additional coil or coils for this in the electric engine preferably added to or inherently built in the rotor so that for example the engine can be used as a special efficient transformer preferably even without actually rotating the engine (which can work much more efficiently than for example normal 3-phase transformers since the engine can act this way like a unified large core for 3 transformers that share the same large core, thus making good advantage from equipment that is mostly already in the car anyway). This is preferably done for example by temporarily disconnecting the engine's electrical power unit from the typical 3 coils that are normally used in the stator when driving the car and powering instead preferably with only two polarities the coil or coils of, the rotor, so that the correct voltage and frequency is drawn preferably as a

3 phase AC current from the stator coils preferably with the desired parameters needed by the electric company. This is preferably accompanied for example by mechanically . 24/12/08 Yaron Mayer & Haim Gadassi 55/304 preventing the rotor from rotating if needed, and/or by appropriate cooling of the engine and/or of power unit and/or the relevant circuits or coils during this process.
Another possible variation in that a similar configuration can be used also for example during the recharging of the car's battery or batteries so that for example the 3 phases of the stator are connected to AC input from the network but preferably in an order or way that does not cause the engine's rotor to turn, and the current for the recharging is then preferably drawn out of the coil or coils of the rotor, and thus for example less diodes are needed for the diode bridge that rectifies the AC
current and turns it into DC. Another possible variation is that for example preferably the recharge posts can for example automatically route sets of cars for example when in V2G mode for example in a way that uses their step-down units (which are normally used when driving the engine) for example so that one or two or more car batteries are used serially in one direction and one or two or more car batteries are used in the opposite direction, so that synchronized change in their step-down units creates the desired AC voltage and cycles, and/or for example if the car includes internal battery elements which can be routed more serially for higher voltage during recharge this can preferably also be similarly used for example as desired while drawing back energy to the grid for example in V2G mode. Another possible variatiQn is that for example at least in some places for example within the same area or parking lot there are also for example at least some DC line connections between at least some recharge posts so that for example they can also transfer energy directly in DC more for example from vehicle to vehicle, which can be called for example V2V (so that for example this can be used for example to for example temporarily supply energy for example to the small number of fast rechargers) or for example to other nearby local devices, and preferably this is done for example by automatic serial rerouting of at least some of the connections for example between groups of recharge posts and/or for example fast multiplexing of the lines so that multiple DC inputs can behave in desired aggregations of voltage and/or amperage. In addition, preferably for example when users temporarily freeze their subscription for example for a few weeks or other period for example due to traveling out of the country or other reasons as explained elsewhere in this application, preferably during this period preferably they are requested by the service provider to leave their car connected for example to the recharge post in their normal parking place or some other recharge post so that the service provider can for example utilize their car's battery or batteries for V2G services preferably if needed also to a substantially larger extent than batteries in cars that are being used, since until the user returns the service provider can enable for example even considerably deeper draining of the battery as needed, and preferably this enables the service provider also to offer the user preferably special credit or revenue during this period for example out of the revenue which the service provider receives from the electric company for this service, so that for example if the user already fmished paying for the car and/or the battery he/she can preferably receive a net income from the service provider during that time and/or for example a credit that enables for example free energy or mileage for example for certain time or amount of energy or mileage afterwards. However, since even for example fast Ml batteries or similar advanced fast batteries still have a limited number of available recharge cycles, such vehicle-to-grid movements of energy can shorten the life of the battery, so preferably this is done only for example if the driver agrees to this in advance and/or 24/12/08 Yaron Mayer & Haim Gadassi 56/304 is done only in rare cases of for example overload emergency or other emergency and/or is for example accompanied by monetary compensation and/or credit points for example to the driver and/or for example to the service provider (for example if the batteries are owned by the service provider, as suggested by Agassi, and even in this case as indicated above preferably at least part of the revenue is shared with the car's owner for example in order to increase his/her motivation to always connect the car to an available recharge post even if no recharge is currently needed and to accept the fact that many times the battery will not be 100% full), and/or for example this is done only or mainly with cars that have for example one or more super capacitors instead of batteries, or other technologies in which the number of recharge cycles is much larger or for example almost unlimited or with batteries where small-range discharge-recharge cycles of for example up to 10-20% have only relatively small effects on the battery's life. In addition, preferably the user can for example see preferably anytime for example on the car's computer (for example based on automatic updates from the service provider's main computers) and/or for example on the service provider's web site and/or for example on the electric company's web site and/or for example on monthly bills or reports from the electric company or from the service provider for example an automatic summary of for example how much revenue or credit points or for example deductions in monthly bills or for example over other periods the user has received for example based on the V2G services. Another possible variation is that preferably the electric car marketing and/or the marketing of the service provider's services are preferably also based for example on preferably recursive Multi-Level Marketing (MLM), so that for example users who get additional users to join the service preferably get various reductions and/or other benefits preferably both to themselves and at least to a certain extent also to the people who joined through them, and preferably these benefits extend at least to a certain limit and/or certain tree-depth also recursively so that they can also benefit something when the additional people which they brought bring additional people on their turn and preferably for example users who agree to participate in this marketing for example add preferably attention-drawing stickers on their car for example with their phone number and an invitation to inquire about getting such cars with a reduced deal and/or subscription fee and/or other extra benefits. In addition, such V2G (Vehicle to Grid) features preferably also take into account car priorities and/or other relevant parameters and/or patterns and/or statistics preferably according to the same or similar criteria as those which are preferably used in deciding recharge priorities, which also means that preferably if there is an intermediary service provider other then the electric company, preferably the electric company does not take any energy back directly from the cars but this is done again preferably through the service provider (which is more preferable), and/or for example if it is done directly by the electric company then the electric company preferably gets preferably automatically from the service provider the relevant instructions about car priorities and/or other parameters and/or needs as explained above (however if it is done this way then preferably the electric company's main computers preferably also automatically update the service provider's main computers in preferably real time about exactly when in is done and with which cars or recharge posts in order to avoid for example conflicting recharge instructions from the service provider, and/or for example the car's computer for example automatically updates directly the service provider's main computers for 24/12/08 Yaron Mayer & Haim Gadassi 57/304 example when the car computer or the recharger has been ordered or requested by the electric company to draw energy from the battery instead of recharging it), and of course it is preferably properly recorded for example by the service provider's main computers and/or by the electric company's main computers and/or by the car's computer and/or by the recharge post so that when the car gets the energy back again it is not calculated by mistake as if it has been given more energy than the net energy it actually received. Another possible variation is that preferably this is done also for example with at least some of the batteries at the battery swap stations (which can be called for example B2G - Battery-to-Grid, which means that preferably they offer the electric company the same or similar services as V2G, but from swapped batteries which are currently not within a car) - since for example while batteries are staying at the battery swap station they can also be used the same way for offering for example up and down ancillary regulation services or other B2G services for the electric companies. This is preferably done for example by connecting the batteries to individual recharges which contain also the inverter for converting to AC and drawing energy back from the batteries and/or for example by using serial rechargers which deal with multiple serially linked batteries which are preferably pre-sorted for homogeneity as explained elsewhere in this application, so that these serial rechargers can preferably also draw energy from the batteries and convert it to AC and can preferably supply the electric company directly with higher voltage AC (such as for example 1000 Volts or more or even a few thousand volts or more) which can preferably be automatically regulated into the appropriate voltage and cycles as needed by the electric company and can preferably be supplied preferably directly for example to high voltage lines. This also means that at least some of the recharged batteries at the swap station will always be for example at most only 80% full at any given time or for example between 80-100 (or other reasonable range) for example especially at peak demand time for example at mid-day, but this is no problem since as explained elsewhere in this application preferably the car priorities and/or special or specific or current needs are used also in the battery swap station so that for example cars that need to go less far or have lower priority are preferably offered less full batteries at least if there in an insufficient number of fully charged batteries at the time and preferably the net difference between the charge state of the car's incoming batteries and the charge state of the swapped batteries is preferably calculated and automatically sent to the service provider's main computers for keeping track of the amount of net energy supplied to each car, and preferably users receive credit points and/or avoid debit points for agreeing to receive less than full batteries if they don't really need completely full batteries, as explained already elsewhere in this application.
(Preferably the swap station gets the car priorities for example automatically from the car's computer and/or for example by automatic updates from the service provider's main computers). In addition, preferably the battery swap stations use the statistics about the car priorities and/or needs (which it preferably gets directly from the service provider's main computers) to plan the desired distribution of percentages of various recharge states of the batteries, so that for example if 20% of the cars than reach the swap station need more or less 100% full batteries then preferably the swap station makes sure that for example at least 20% of the batteries are always fully charged - for example by automatically setting different parameters for each set of batteries for example for their recharge priorities and/or for example 24/12/08 Yaron Mayer & Haim Gadassi 58/304 for the allowed amount or percent of discharge by the ancillary or other B2G
services (for example by direct programming commands to the relevant rechargers, so that for example some rechargers allow to discharge up to 20% from the batteries that are connected to them or for example allow reducing the charge only down to 80%, others enable for example only down to 90%, etc.,) or for example by putting a certain percent of the batteries in recharges that don't enable the ancillary or other B2G services or for example by removing and keeping the relevant percentage of batteries away from the recharges once they have been fully charged. In addition, since after the car batteries (for example after 7 or 10 years or other period) reach a level of reduced capacity (of for example 70% or less) in which they are preferably cycled out of car use and replaced by newer batteries they can still continue to be used for the ancillary or other B2G services for the electric companies, preferably for example if the batteries are owned by the service provider the batteries which are cycled out-of commission for car use are preferably still used by the service provider for example by selling or renting them to electric companies or for example by continuing to offer the ancillary services or other B2G services to the electric companies for example by connecting them to special individual rechargers with the appropriate inverters for example at the swap stations or for example to serial rechargers of groups of batteries as explained above, so that for example a certain part of the individual rechargers and/or serial rechargers at the swap station are dedicated for connecting older batteries to the network just for the ancillary or other B2G services, and/or for example special similar stations are built for example in more remote and cheaper large areas (but preferably not too far from the centers of the electric company generators or centers or from the high demand areas) so that there are for example large arrays of these recharges and inverters in areas where they are used only for out-of-commission car batteries. This way for example if the electric company pays example $1000 a year for these services per battery, if the service provider can keep offering this service for example on average with each battery for example even for 10 years after removing it from car uses, then for example the service provider can make over 20 years for example $20,000 back on each battery that cost for example $6,000-10,000 initially - thus practically nullifying the cost of the battery including the financing cost and making a nice profit of it even beyond its use for driving the electric cars. In addition, the service provider can this way for example also buy used batteries for example from other car owners which owed their own batteries after a their batteries after few years reach a level of reduced capacity that makes them no longer desirable for use in the cars, and/or for example offer trade-in services where owners of old reduced capacity batteries can swap them for new batteries or for example can sign-in for starting to use the service provider owned batteries for example for a reduced rate by trading-in their old reduced capacity batteries. This is preferably done for example at least during the transition period when there is still 'an insufficient number of electric cars in the area or in the country to fulfill all the V2G
needs of the electric companies. This can similarly be done for example while building new battery,swap stations in new areas or countries where the penetration of electric cars is still non-existent or new or low, so that for example the service provider can transfer old out-of-car-cycle batteries from areas where they were used in electric cars for a sufficient number of years to new areas where the infra-structure is only being built now - since during this time in the new area there can be a transition 24/12/08 Yaron Mayer & Haim Gadassi 59/304 period in which the newly constructed battery swap stations have little work and thus most of the rechargers on these swap station would otherwise be sitting idle unless used for example for B2G services for example with old batteries.
Another possible variation is that for example the service provider also buys some stock of new batteries in advance for example for the new swap stations or for example for offering them in as leased batteries for new clients and thus preferably starts using also them for example for B2G services until called into actual car service.
In addition, as described already elsewhere in this application, preferably the service provider creates in advance example at least in some places stubs or stems or interfaces preferably underground in advance in places where future rechargers or recharge posts can be added, preferably this is done also in battery swap stations, so that for example if the swap station uses an individual recharger for each battery then preferably underground interfaces are added in advance for new recharges so that they can be easily or modularly added later as needed, and if at least some serial rechragers are used which recharge each more than one battery at the same time then preferably they similarly have at least the underground or high-above-ground higher voltage relevant infrastructure installed in advance so that additional serial recharges can also be added later preferably to a modular interface for example without having to dig tunnels or canals again. Similarly, for example if the swap station includes also at least a certain percent of high-speed rechargers then as explained elsewhere in this application preferably they can use also for example underground cooling at least part of the way or for example they can be on top of each other, for example with liquid cooling pipes which go up for example to a large heat dissipation unit for example on the roof preferably including also air conditioners, and/or similar liquid cooling and/or heat dissipation units are used also for example on the roof also for at least some of the normal speed rechargers in the swap station, or for example the same heat dissipation units for example on the roof same both normal speed and high-speed of rechargers and/or for example both individual rechargers and serial multi-battery recharges and/or for example rechargers which recharge multiple batteries in parallel and thus preferably share at least part of the circuitry, thus saving costs. Of course users that own their batteries can instead prefer after the battery is removed from car use to buy an extra recharger and inverter or for example remove them from their old car for example if the old car has also other problems and for example keep their old batteries for example in their basement or garage and thus offer the ancillary or other B2G services directly to the electric company, but the service provider can for example offer the electric company also automatic aggregation services and/or the existing network of commanding the rechargers so that for example the electric company will prefer to continue doing this through the service provider. Another possible variation is that, as suggested recently for example by Shai Agassi's company Better Place, the out-of-commission (i.e. out-of-car-use) car batteries can be used for example in house basements for the user's own needs of charging cheaply at night for example from the electric company while the rates are cheaper (or for example from wind turbines for example on the roof or other renewable sources) and using the energy at home.
However, if this is done, preferably this is improved so that for example this is preferably done similarly also for example in industrial plants or other businesses where even more energy might be needed during daytime, and preferably the house's or plant's or business's smart meter or for example the user's normal 24/12/08 Yaron Mayer & Haim Gadassi 60/304 computers (for example through communication with the battery or the smart meter and/or through for example automatic updates from the electric company's web site) or for example the electric company's web site (for example through its communication with the smart meter), can preferably for example automatically recommend to the user and/or for example automatically switch the battery usage on or off as needed preferably in an optimal way for example based on his/her normal use pattern for example when it is best to use the energy from the battery and when to use it from the electric company (for example if the user needs large energy during peak time but in the morning it is still relatively cheap then it might be better for example to still use the energy from the electric company in the morning and then for example automatically switch to the battery power for example at noon or when peak demand time starts, or for example if the battery charge is sufficient for the entire day use then for example it is better to start using the battery as soon as needed), and/or for example when it is best to sell for example energy from photovoltaic cells or wind turbines or other sources directly back to the electric company and when it is best to use them to charge the battery. In addition, preferably the two types of use are preferably integrated so that the same batteries are preferably used both for cheap or free charging at night for use during the day and for B2G services, so that for example the user is preferably automatically offered for example by the electric company a plan in which his/her batteries are also automatically used by the electric company for B2G as needed and the user gets automatically compensation or electric bill reductions accordingly, and/or for example the electric company can also lease to users for example the needed rechargers and/or inverters and/or for example controllers and/or other needed equipment as part of the deal. This way preferably the decision of when to route energy to or from the battery and/or for example when to sell energy to the electric company directly or to use it are preferably carried out automatically preferably for example by remote commands from the electric company for example to the recharger and/or inverters that control the battery and/or for example to controller that control the energy routing from the renewable energy sources such as for example wind turbines or solar energy sources which the user owns. In this case preferably the service provider can for example sell the old out-of-car-use batteries to consumers or companies and/or for example the service provider leases the batteries to them (and/or for example sells them or leases to them the needed rechargers and/or inverters and/or for example controllers and/or other needed equipment) for example for a certain monthly fee and/or for example the service provider gets part of the revenues from the electric company or from the user for these services or at least for the B2G services, and/or for example the service provider for example through its main computers for example is the one that offers the user the above described automatic recommendations and/or automatic decisions when and how to use the battery or to provide the B2G services and/or when and how to sell for example energy from renewable energy directly to the electric company, as explained above. In addition preferably the service provider and/or the electric company preferably use for the B2G preferably similarly user priorities for example based on their usage patterns and/or other statistics and/or parameters and/or special or specific or current needs as described elsewhere for example for the car recharging and/or for the V2G (so that preferably these usage patterns and/or other statistics and/or parameters are similarly preferably collected automatically for 24/12/08 Yaron Mayer & Haim Gadassi 61/304 example by the service provider's main computers and/or by the electric company's main computers and preferably in addition the user can for example through the web site of the electric company or of the service provider for example enter specific special or current needs for example for the next few days or for example until further notice), so that also when using B2G services preferably the service provider or the electric company can when needed preferably automatically draw energy mainly for example from batteries which are least needed by the users at that time.
Similarly preferably when recharging such out-of-car-use batteries for example at night preferably the service provider and/or the electric company also take into account the relevant user priorities which are preferably based as explained above for example on their usage patterns and/or other statistics and/or parameters and/or special or specific or current needs, preferably like when recharging the batteries that are used in electric cars, and/or preferably in addition preferably the recharging of the out-of-car-use batteries is preferably done properly in coordination with the recharging of the batteries that are still used in cars, so that for example the relevant priorities and/or other parameters are preferably taken into account both among batteries that are used in cars and among out-of-car-use batteries, and in addition preferably for example car batteries have in general higher priority than out-of-car-use batteries, and/or for example both sets of priorities are integrated into the same set while preferably giving automatically higher priority scores to batteries that are used in cars, i.e. for example using the usage type (such as for example in or out of car-use) as one of the important parameters. Similarly for example the priorities for recharging for example replaced batteries for example at the swap stations for example at night are preferably also determined for example based on taking into account also the relative priorities for example for recharging batteries which are currently in cars, and/or preferably in addition preferably also various statistics which are relevant to the swap stations so that for example swap stations which for example based on their location for example typically get large numbers of incoming users for example in the morning or early morning preferably for example get higher recharge priorities at night then for example swap stations which get more users for example at later hours, etc., and preferably the statistic patterns can take into account for example also different behaviors for example based on week days such as for example different behaviors on weekends. Preferably in general for example the recharge at night is preferably sufficient for recharging by early morning for example all or most of the batteries within electric cars preferably to full or almost dull capacity and preferably also at least a certain needed percent or amount of the batteries in the swap stations or for example most or all of them, so that preferably for example the priorities at night are used mainly for example in case of problems for example if eventually there is insufficient wind power and/or for example insufficient energy for example from other renewable sources for example to fully charge all of the cars for example in the country or in the relevant area or for example to reach the desired percent of renewable energy usage, and/or for example there is insufficient power from the renewable energy sources plus the current or desired amount or percent of night-time operating power stations to fully charge all the of the cars, and/or for example the priorities are used to make sure that users who need to use their car earlier in the morning will have full or sufficient charge on time, as explained also elsewhere in this application, so that preferably the service provider and/or the electric company preferably in general strive to recharge 24/12/08 Yaron Mayer & Haim Gadassi 62/304 as many cars as possible to as full an extent as possible for example especially during night time (since this reduces the chance that people will need recharge during daytime and/or peak time and/or the amount of daytime or peak time recharge needed, and since for example most people who need for example an out of town trip out of the recharge range will typically go to a battery swap station instead of recharging during daytime), but for example if additional unnecessary recharge would mean for example having to put into action for example at the night for example one or more power stations or for example older carbon burning power stations which are otherwise not needed, then for example the service provider and/or the electric company can for example decide to limit the night recharges at a certain point according to the relevant priorities and/or statistics and/or additional criteria and/or considerations. Preferably both in the recharging of the electric cars and/or for example in the recharging of out-of-car-use batteries and/or for example in V2G uses and/or B2G uses preferably for example the main computers of the service provider and/or of the electric company preferably for example automatically log and/or keep statistics also of cases when users for example enter special or current or specific needs and thus get temporarily higher priorities but eventually don't use them, so that for example in such cases or for example beyond certain allowed deviations preferably such users are for example charged extra for such false alarms or misuse of the system and/or accumulate for example various debit points and/or lose credit points for this, and/or for example users are charged extra anyway (for example in money and/or credit points and/or debit points) for example for recharge or fast recharge for example during daytime or peak time for example in general or for example when exceeding a certain quota, as explained also elsewhere in this application. Of course, like other features of this invention various combinations of these and/or other variations can also _be used.
Another possible variation is that preferably at least some fast car batteries are constructed for example from cells similar in design and/or function to the biological power cells of electric eels, which are already used for example for powering some organ implants, which can preferably be recharged an almost infinite number of times.
However, since the driver's needs might for example change in certain days or times, preferably users can also over-ride the normal priorities, for example by requesting recharge priority when needed, which can be done for example based on some preferably slightly increased fees for example at least in higher electric load hours and/or for example based on a certain quota of freely available recharge priorities for example each month (for example up to N free hours or N amount of power for example available freely each months for example during daytime or during peak hours, so that the user pays extra for example only if he/she exceeds this quota, and/or for example the recharge price takes into account anyway the load on the grid so that for example recharge in the night is almost always cheaper than recharge during daytime). Similarly, as explained above, preferably the system takes into account also for example global priorities, so that for example recharging is preferably done mainly at night automatically and/or for example in various hours when the load on the electrical grid is lower, so that for example preferably only or mainly cars that have a sufficiently high priority (for example based on their current battery level and/or their individual needs according to their usage history as explained above and/or for example based on special request) are recharged during problematic hours and preferably most electric cars are recharged during night 24/12/08 Yaron Mayer & Haim Gadassi 63/304 hours, for example fully if possible or for example less the fully if a full charge as not needed or for example if there is still a problem of resources and priorities even at night, at least initially. Another possible variation is that the user can for example program for example the desired recharge hours for example in advance for example on a weekly basis (i.e. for example as a repeating schedule in terms of days of the week). and/or for example with specific dates if there is a special need for example on a certain day, for example by entering it into the car's computer or for example into a smart card (or for example by entering the planed destinations and approximate planned times of departure so that the needed recharge times can be for example calculated automatically), so that it is preferably communicated to the recharger or recharge post automatically when hooking to it, or for example by updating the data with the user's subscription Identification on the web site of the service in which the user is a member, but again, as explained above, this is preferably taken into account with the above limitations, so that for example recharging is encouraged mainly at night hours and/or is preferably avoided for example in rush hours unless necessary. Another possible variation is that for example the service provider's web page and/or for example the car's computer (for example from its internal database and/or by communication with the recharger or recharge post or for example by update for example through cellular communication) and/or for example the recharger or recharge post (for example through its own interactive display (which preferably also has a keyboard) or through the car's display (which preferably also has a keyboard and preferably can also respond to voice at least for some menu choices) - by communication with the car's computer) can preferably for example automatically recommend to the user (for example based on the car's profile or statistical parameters as explained above and/or on the user's specific needs at the present, such as for example the need to drive today to a more remote place than usual) - for example if according to the distance of the fed-in destination and/or for example the current state of the batteries and/or for example the recharge facilities at the destination and/or based on the price difference between recharge now and recharge at night (and/or for example based on the user's remaining free quota of recharges allowed at daytime or peak hours for example for that month or other period) and/or other parameters - it is for example recommended to recharge now or wait for night hours or for example it is recommended to recharge now only a certain amount of energy or for example certain percent of the battery, or for example it is recommended to go instead to the near battery-swap service station (for example if it is sufficiently close, for example if the user needs to go to a far place and these are peak hours) in order to swap the batteries or for example recharge them within a few minutes for example from the station's own high speed batteries or for example super capacitors, thus recharging at a cost independent from the electric company's charge at those hours, and preferably this is accompanied by information about how to get to the nearest service station or stations if relevant and preferably by automatic estimates of the cost in each alternative and/or for example showing the user his/her remaining quota of daytime or peak hour recharges for that month or other period, and then the user can for example choose the more preferred alternative and/or for example make further adjustments. Preferably when swapping the batteries preferably the user can also swap for example batteries which are half full or for example almost full or for example at various or any states (for example if the batteries are currently at 50%

24/12/08 Yaron Mayer & Haim Gadassi 64/304 charge but the user has to travel to a far destination) and then preferably the user pays for example just for or in a way that takes into account the charge difference between his current batteries and the full ones or for example gets appropriate credit or debit points for example if this is based on a monthly subscription (and/or for example this is taken into account some other way). Another possible variation is that for example when the user swaps batteries preferably for example the car priorities and/or current needs are also taken into account so that for example if the user needs to drive for a longer distance (for example to another town) he/she is preferably given batteries that are more fully charged and/or for example fully charged and/or for example with higher capacity or for example at their full capacity, and/or for example if the user needs to drive for example for a smaller distance and/or for example if there is for example a temporary shortage of fully charged batteries, the user can also be given for example temporarily for example batteries that are not fuIly recharged, such as for example only for example 80% or 90% charged and/or for example are a few years old and/or have their capacity for example reduced for example to 95% or for example 90%, and in this case also preferably the user pays for example just for or in a way that takes into account the charge difference between his current batteries and the new ones or for example gets appropriate credit or debit points for example if this is based on a monthly subscription and/or this is otherwise taken into account so that only the difference is calculated as energy which the user received, and/or for example the user can get some extra credit for example for agreeing to accept for example temporarily batteries that are not fully charged or for example have a somewhat depleted capacity.

Another possible variation is that for example the service providers which operate public rechargers or recharge posts preferably use their own super capacitors or network of super capacitors to power at least some of the rechargers or recharge posts, so that for example at least some of them can offer recharges at lower rates even at electricity peak hours (for example by using for example underground local super capacitors for example below a parking lot - for example powering a group of recharges, or for example by connecting at least some of the rechargers or recharge posts to separate power lines which are moderated or connected through by the service provider's network of super capacitors, and/or for example by making deals with the electric company so that the recharges are connected normally through the electric company's wires but the service provider for example supplies the electric company with electricity through its own super capacitors which were charged at night and/or for example through its own facilities of renewable energy, such as for example wind or solar, and in return gets for example special rates from the electric company for example at various hours). Preferably the for example monthly (or other period) subscription model is based on a certain constant amount which preferably enables a certain amount of free mileage or energy per month (or other period), preferably including also preferably a certain quota of recharging at peak hours as explained above, and preferably the user has to pay for extra mileage or energy beyond a certain limit of free energy or free miles or kilometers (for example based on the energy consumption or for example based on the actual mileage traveled during that period), and preferably like in cell phone subscriptions users can preferably choose among more than one or multiple available plans, for example 24/12/08 Yamn Mayer & Haim Gadassi 65/304 based on their average for example monthly needs and/or for example based on if they bought the car or got it with the subscription, and/or preferably for example the car's computer and/or for example the service provider's web site can for example recommend to the user for example each month or other period the best recommended plan for him/her for example based on the statistics of his/her mileage and/or other usage patterns for example during the preceding months or other covered period. This also means that preferably for example the car's computer and/or for example the recharger or recharge post can for example also display and/or print for the user for example a monthly (or other period) summary of his/her recharges, for example showing the recharges on a daily basis (for example based or time and/or amount of energy and/or percent of recharge of the battery and/or estimated mileage for which such a recharge is usually sufficient) and/or for example the actual distances traveled (which is for example based on the statistics which the car computer preferably automatically transfers to the main computers through the recharger or recharge post), preferably for example together with the costs and/or credit points and/or for example debit points and/or for example percent of available free quota, and/or for example the various statistics and/or patterns and/or parameters which are used for determining recharge needs and/or priorities, preferably together with for example monthly statistics and/or charts (and/or for example from the beginning of the month until today), preferably through the recharger's or recharge post's automatic communication to the service provider's main computers and/or for example through data accumulated automatically by the car's computer, and/or for example the user can view or print this on the service provider's web site, and/or for example the user can automatically get for example a monthly statement for example with the above monthly summary and/or daily recharge data and/or statistics or any of the above data and/or recommendations, and/or for example various special deal offers, for example like getting the monthly Visa statement. Another possible variation is that the user can for example view on the service provider's web site also for example his/her average energy efficiency and/or for example his/her average speed and/or for example other driving behavior parameters which affect the energy efficiency - preferably also for example in comparison with automatically gathered average statistics of other drivers which are for example using the same electric car model and/or for example in comparison with other models - so that the user can for example see how he/she is doing compared to others and can for example learn about which parameters have most effect on this efficiency. Another possible variation is that for example users can also buy for example a special plan or privilege that for.example gives them higher priority on recharges also in general, for example by paying extra, but preferably if such plans are allowed they preferably only mean that the user's car can for example be recharged for example to a certain extent sooner for example among other cars with the same or similar priority based on their needs, but not for example that the car gets regularly recharged in more expensive hours without any need-based justification, since otherwise such programs could damage the energy efficiency of recharging electrical cars in general. Another possible variation is preferably there are also for example family deals or for example company deals, so that for example in a family that has more than one car or for example in a company with multiple cars, if for example a certain quota of miles or amount of energy is available for example for free or covered for a certain period (such as for example a month, i.e.

24/12/08 Yaron Mayer & Haim Gadassi 66/304 the payment is global through the subscription plan), preferably this can be for example based on a global aggregate of multiple cars, so that for example the family or company has to pay extra only if for example the sum of consumption of all the cars that are in the program for example exceeds the free or covered quota for example for a given month (or other period), and/or for example this can be applied also for example to the quota of available free daytime recharges or peak time recharges. Another possible variation is that for example separate users can transfer credit point or debit points also between them, so that for example a user who has used considerably below the free or covered amount of energy or mileage he/she could have used for example for a certain month can for example transfer at least some of the credit for example to another friend of user who has exceeded the free or covered quota (for example for a certain allowance fee or for example for free or for example for free only within a certain limit), and/or for example users that have used below a certain amount of energy or mileage for example in a given month can for example transfer the credit to the next month (or other period, for example any spare amount or for example only if the under-usage is below a certain threshold), and/or for example users who are for example traveling out of the country for example for a few weeks (or other period) or for example are going out for a few weeks complementary service in the army (or other period) (or for example are not going to use their car for a certain period for some other reason) can preferably for example freeze their subscription, preferably in advance, thus for example paying for the relevant period only for the car and the battery but not for the part that covers for example the free or covered quota of energy or mileage for that month (or other period for example in any of the above variations). Another.possible variation is that for example state or city regulations preferably at least in some places preferably require for example that the service provider who controls the rechargers or recharge posts and/or for example the battery swap stations in that area for example must offer service also for example to competing cars and/or cars that were for example imported by competing importers, since for example controlling the rechargers or recharge posts is like a monopoly and it would be very inefficient if competing suppliers had to install separate recharge networks, and preferably the right to install for example the rechargers or recharge posts in a certain area is won in official tenders, and preferably the service provider has to offer the same recharge prices and/or plans also to owners of cars that were imported by competitors for example at least for users that pay per recharge and/or also for at least some of the available for example monthly (or other period) subscription plans (preferably except for example for the part of the monthly payment that pays for the car and/or for example the part that pays for the battery, for example if the user also has his own battery), and/or for example within certain guidelines or rules that.insure fair use of the monopoly, and/or for example the service provider has to allow the main computers of for example one or more other officially allowed other service providers to use the same network of rechargers or recharge posts, so that for example when a car that belongs to the other service provider connects to the recharger or recharge post, its digital code or for example the user's smart card or other identification means also tells the recharger or recharge post for example to which service or network the car and/or the user belongs, and then for example the recharger or recharge post automatically talks to the main computers of the other service provider for example until the recharge is finished, and preferably the other 24/12/08 Yaron Mayer & Haim Gadassi 67/304 service provider has to pay a certain amount or percentage to the service provider that owns the recharges for example for the time the recharger or recharge post is occupied and/or for example according to the amount of energy transferred.
However, preferably the service provider has the right to require a certain standard, so that for example only certain types of batteries and/or for example certain standard interfaces are allowed or supported. Preferably the monthly quota of allowed free recharge hours or energy for example during daytime or during peak time (for example based on the amount of time and/or for example the amount of energy drawn during these hours) can preferably be defined for example based on an absolute amount and/or for example based on percentages of the total recharge time and/or for example mileage during that period. In addition, if the user is for example in a subscription arrangement in which he/she gets the car for free and has to pay a constant fee per month which includes the energy (such as for example around $500-600 per month), and after for example 4 years the car becomes his/hers -as Shai Agassi has suggested, preferably this model is improved so that after this period in which for example the car and preferably also the battery has been paid for, preferably the user can continue the subscription under similar conditions, except that for example the monthly payments become smaller with the part of the amount that was previously going for paying for the car and/or battery.
Another possible variation is that preferably this change doesn't happen sharply at one point in time but for example the payments gradually become smaller as the time from the beginning of the subscription passes. Another possible variation is that for example users who bought the car itself elsewhere or for example users that prefer to buy the car itself in advance from the service provider can preferably enter a similar subscription, in which preferably a considerably lower monthly fee is paid, which covers for example only the battery and the energy. Preferably all of the above described types of subscriptions preferably include automatic insurance for the battery or batteries, so that for example the service provider is responsible for replacing the battery even for example when it reaches the end of its life time. And preferably for example when selling such cars 2nd hand to other people preferably the seller is allowed for example to transfer the same subscription arrangements and/or plans (i.e. preferably also including the relevant obligations) to the buyer without losing for example seniority and/or accumulated credit points and/or other rights (which means that for example if the original owner got the car for free and only paid for example a monthly sum that included both a payment for the car and a payment for the lease of the battery plus the energy so that for example the original owner would own the car for example in 4 or 5 years, preferably the buyer pays the seller a certain price for the accumulated partial ownership of the car and takes upon himself the obligation to continue the appropriate payments for example to the service provider) and preferably the buyer can also for example add years to these subscriptions, and/or for example the service provider preferably has similar or special deals and/or service offers for people who buy such cars second hand for example even if they were not on such service plans before, and/or the buyer can switch programs while preferably using for example credit points or for example seniority and/or other rights which were sold to him/her by the seller, and/or for example users can also sell back or for example trade-in the car and/or for example credit points and/or other rights to the service provider or for example buy such second hand electric cars from the service provider, so that for example if the user 24/12/08 Yaron Mayer & Haim Gadassi 68/304 pays only a monthly amount for the car and the service, preferably the part of the amount that covers the cost of the car is of course accordingly smaller when the user gets a second hand car and/or end sooner (for example when the original N
years from the original buying of the car in which the monthly payments include the payments for the car end). This is very important since many people decide about buying specific cars also based on taking in account in advance what will happen if they will want to sell them for example after a few years, and many people for example in Israel and in other countries prefer to buy cars only 2nd hand (or third hand, etc). The preferred stages of this recharge process for example in the Service Provider's recharge posts (which as explained above can be for'example in the streets in residential areas and/or in town centers and/or work places and/or other parking lots), are shown in more detail in Fig. 4.

Another problem is that for example since various electric car models will be available, for example both within the same car manufacturer and between different car manufacturers, and/or for example at least some types of bigger cars might for example require more batteries or for example a somewhat different position of the battery or batteries or battery cells within the car, for example the battery swap service stations might have a considerable standardization problem or for example might be able to handle only certain types of cars or batteries. So preferably this is improved so that for example certain standards or standard interfaces exist (for example in a way reminiscent of the various types of standard PCI slots or for example USB or firewire in computers), so that for example various types of batteries can have the same interface for example in terms of digital socket or wireless for communicating their digital data and/or for example can come with a standard envelope that fits in the battery cell in the car as explained elsewhere in this application, and/or preferably there are for example special mechanical and/or for example electronic and/or for example electromagnetic and/or for example optical markers and/or other markers which preferably mark the position and/or borders of the battery cell or the battery or its envelope and can preferably be automatically identified for example by the elements or units that swap the batteries, and/or for example there are additional or similar such markers for example on the car itself that indicate for example the model of the car and/or for example other parameters so that for example if some additional info is needed it can be accesses for example from a database according to the car model (such as for example additional relevant parameters about the location of the battery and/or special features that are relevant for that model). Preferably the unit that performs the battery swap is a for example a mobile robotic autonomous small vehicle (and/or for example which is also controlled at least partially by a human operator) that can for example crawl under the car (for example completely or for example only its arms crawl below the car) or more preferably for example can access the battery for example from the back or side of the car, and can preferably locate automatically preferably the exact location of the battery cell, remove the battery, and insert the replacement battery, and/or for example the battery can be pulled or slid in or out for example from the back of the car (or for example from the right or for example from the left side) for example by robotic arms that come out for example from a wall or other vertical device at the swap post, so that for example the arms can preferably for example slide for example up or down and/or sideways and/or extend themselves and/or shorten 24/12/08 Yaron Mayer & Haim Gadassi 69/304 themselves and/or or rotate automatically according to the automatically located position of the battery cell (access for example through the back or side of car is more preferable since it can be made easily and cheaply and it is easier for example to slide the battery in and out horizontally, it has more room for the interface, and it can be easily used also for swapping batteries for example on the side of the road by a swap unit that approaches the car from behind, as explained also elsewhere in this application), so that in either of these variations preferably the battery can be replaced without for example having to lift the car or for example having to access it from a hole below. This has also the further advantage that for example the same kind of configuration and for example autonomous robotic or human controlled vehicle can be used also for example by lowering it from a service truck if for example the battery needs to be replaced on the side of a road, as explained also elsewhere in this application. If such robotic preferably low vehicles are used they preferably have for example 3 or 4 or more small wheels which can preferably all rotate preferably in any direction. On the other hand, if for example the battery has to be swapped from below the car in a way that cannot be handled by simply crawling below the car (which is much less preferable), preferably in the swap station the cars approach for example service positions for example in a format similar to fueling positions, except that preferably there are markings and/or mechanical guides which guide the car to a certain position, and preferably this is designed on a floating floor or a floor that has one or more chambers below it, and preferably for example some light changes for example from red to green or other color only if the car is aligned properly (and/or for example other visual and/or auditory indications are used for this), and preferably there is hole in the floor below the car which is preferably surrounded by a vertical border so that preferably the car's wheels cannot accidentally fall into the hole while moving in or out of the swap post, and/or for example only if the car is aligned properly for example a door opens below the car, and preferably for example one of these robotic vehicles handles the battery swap from below, and/or for example before the hole opens for example some mechanical guides come up automatically and lock the car in position and for example when the swap is finished they are for example automatically lowered so that the car can move out even if for example there are other cars in front of it. In this case for example after the robot's arms are located below the battery compartment for example a sliding door opens and the battery remains caught in position for example by horizontal metal strips or for example hooks for example from the sides and these strips or hooks can preferably be released for example automatically after the robot arms are attached to the battery. In this case preferably for example when a battery swap is needed for example when giving service for example at the side of the road, preferably the service truck carries also for example a mobile ramp which is for example in the shape of two metal slopes which the car can be rolled on, so that the robotic low vehicle can preferably enter below the car from the higher side of the slope. Preferably these low robotic vehicles can also work similarly for example if the swap is done for example in an installation similar to a car wash position, in which the car is moved forward automatically (and then, again, for example the robotic vehicles can for example access the battery for example from behind the car (or for example from the right or left side) or for example from below and can preferably automatically locate the exact position of the battery cell as explained above), but the above variations are more preferable 24/12/08 Yaron Mayer & Haim Gadassi 70/304 since they are cheaper (especially for example if the battery can be pulled or slid in or out for example from the back or side of the car), allow putting more swapping positions in the same area, and enable cars to move in and out more freely at the same time instead of having to wait in line for the previous cars to finish.
In addition, if the battery has to be removed from below the necessary opening at the bottom of the car might weaken chassis, so preferably if the battery is removed from below then preferably when the battery compartment door is closed preferably the door preferably automatically becomes interlocked preferably with the chassis, for example by locking it automatically also for example with knits to the chassis, and/or for example the frame of the hole that needs to exist in the chassis for example below (or for example on the side of the car or for example on the back of the car if the battery is swapped from there) is preferably especially reinforced for example preferably especially around the edges, for example by making the lips or frame of the hole for example considerably thicker than the rest of the chassis (for example by bending the metal for example in 90 degrees and/or for example in degrees so that for example the entrance to the hole is like a rectangular tunnel for example a few centimeters long) and/or for example adding for example various reinforcement strips for example next to the hole or the tunnel or near it or around it.
However, even if the battery is removed from below the car, preferably it can still be removed by a swap unit which is standing at the side of the car, for example by lowering automatically a drawer below the car, as explained below. Another possible variation is that for example the user can or for example has to for example press from within the car a button that preferably wo'rks only while in parking (and preferably for example only after an appropriate code or identification has been entered, and/or for example after the car communicate digitally with the service station or with the battery swap unit, as explained also elsewhere in this application), in order to allow opening the battery cell and replacing the battery, and/or for example the cell that contains the battery contains for example on its bottom for example internal rollers or other mechanical moving parts that can help slide the battery in or out and are for example passive and/or for example can be actively moved by the car's computer (preferably by taking power for this from the small front battery) and thus for example can help the battery swap units, however if such arrangements are used preferably the battery swap service can also overcome it and switch the battery even without them for example in case the front battery is also empty or for example in case of malfunction. Preferably at least the front cover or door of the battery compartment is removed automatically by the car (for example if the battery is slid out horizontally for example through one of the sides of the car or for example through the back or the front of the car, and if the car also automatically pushes the battery out for example at least partially, preferably it pushes it so that for example a quarter of the battery (or another reasonable ratio) sticks out of the car and preferably there are for example protrusions or automatic brakes that stop it from sliding out any further so that preferably it cannot slide and fall even if the car is standing for example on tilted ground, and then after the swap device attaches itself to the battery for example from below and/or from the sides, the brakes or protrusions are preferably released so that the battery can be further extracted and swapped with the more charged battery, and/or for example the battery is automatically extracted by the car for example to full or almost full extent for example on a drawer, except that preferably at least part of the front wall of the 24/12/08 Yaron Mayer & Haim Gadassi 71/304 drawer (i.e. the wall that comes out first as the drawer is opened) is missing so that for example the battery is held at the front only at the corners and/or for example held by parts of the front wall which are preferably lower than the other walls (for example just 2-3 cm in height and for example sway from the positions in which the arms have to enter) and the battery is preferably thus accessible for example from where the front wall would normally be in a drawer, so that for example the swap unit's arms can be moved from the missing parts of the front wall preferably to a position under the battery. As explained also elsewhere in this application, preferably the autonomous and/or human controlled battery swap unit is preferably based on or similar to a fork lift, so that its arms (preferably for example at least 2 or 3 arms) can preferably reach below the battery, and preferably the battery has for example at least 3 or 3 hollow canals at its bottom which preferably continue all the way below it so that preferably the fork arms can enter below these canals and can preferably reach till the end of the battery and then can preferably pick it up.
Preferably the canals are bigger in height and preferably also in width than the thickness of the fork arms and are for example square or for example rectangular shaped (and/or for example the canals are wider at the lower edge that is more away from the battery, for example with a cross section for example like an inverted V, and preferably in that case the fork arms preferably have a matching triangular shape), so that preferably while the fork arms are being inserted or removed in the canals the fork arms can preferably be moved in or out in the air in the canals height-wise and/or width-wise so that preferably there is no friction or at least they only partially touch the canal walls and/or the bottom of the compartment until they reach their destination (in order to reduce mechanical wear), and preferably when the fork arms are lifted preferably they fit exactly into the canals.
Preferably the ends of the fork arms have hooks that go up so that when the arms are lifted after they have been inserted from below till the end of the battery these hooks preferably hold the battery also at the end, thus preventing it from falling off at the end of the fork arms preferably even if the car and/or the swap unit are standing for example on somewhat tilted ground. Another possible variation is. that for example these canals are also closed from below for example like pipes that go for example below the battery or for example through it. Another possible variation is that for example these hooks are for example folded within the fork arms while the arms are being inserted or removed and the hooks are preferably raised automatically when they reach the end of the battery (i.e. the part of the battery that is most away from the battery swap unit), and/or for example there are hooks for example at the base of the arms and for example rings or other shapes at the front part of the battery (i.e. the part that is closest the battery swap unit), so that for example when the arms are fully inserted the hooks also hold the battery for example through the front rings. If the battery is for example on a drawer that has been extracted by the car, preferably the fork arms simply pick the battery up and remove it and the for example insert the new battery from above, and/or for example the front wall of the drawer can then be further opened and the battery removed horizontally and the preferably the new battery is inserted in a similar way, and then the arms are preferably removed and the drawer enters the car again. Preferably such a drawer or for example bended arms or for example similar device can also be used for example if the battery is removed from below the car, so that for example the car automatically lowers the battery for example on a drawer with a missing or partial front wall and preferably 24/12/08 Yaron Mayer & Haim Gadassi 72/304 stoppers that prevent the battery from sliding out - for example by or low front wall of for example only 1-3 centimeters or other reasonable height and for example with gaps where the arms have to enter, so that for example after the arms are fully inserted for example below the battery they can for example lift the battery above the low front wall and thus pull the battery out sideway and preferably insert the charged battery preferably through the same process in reverse, and/or for example the battery has preferably appropriate protrusions and/or for example holes or grooves for example on the sides so that the robotic arms can for example easily pick up the battery from the sides or for example pick up the battery first from the sides for example by one or a few centimeters and then insert for example one or more additional arms also below the battery. This has the advantage that in this case for example if the drawer or similar device moves sufficiently below the car (for example a few centimeters or less above the ground or for example completely down to the ground, which can also increase stability) so that for example there are at least a few centimeters or more between the top of the battery and the bottom of the car, this can enable the robot to remove and replace the battery for example even without exact precision of movement compared to the car and/or without the need to attach itself also to the car as explained below. In addition preferably the battery swap process is done in a way that protects the battery from and/or compensates for example for movements of the car up or down and/or tilting for example due to the weight change and/or change in the center of weights while pulling the battery out or pushing the new battery in, which can be done for example by any of the methods described below. For example if the battery is still in a compartment in the car at least partially when the arms are preferably fully inserted below it, then preferably the compartment's top wall is preferably a height of for example 1 or 2 centimeters (or other reasonable distance above the top edge of the battery, so that preferably the anns lift the battery for example about half of the available height (so that for example the battery is in the air within the compartment preferably with the same gap between the battery and the top of the compartment and between the battery and the bottom of the compartment, so that preferably while the battery is removed it does not touch the bottom or the top and/or for example there is also a similar gap sideways, and/or for example as explained already elsewhere in this application preferably there are for example rollers for example on the bottom (and/or for example also on the sides) of the compartment so that the battery can preferably be easily rolled on these rollers in or out. However, preferably after the battery is inserted into the compartment and the compartment door is closed preferably there are for example springs or other elements that for example come down from the top (and/or for example also similarly from the sides) and lock the battery in position to prevent for example jumps relative to the compartment while driving, and/or for example the top of the compartment itself is moved down towards the batteries preferably when the battery is locked in and for example moves up again during the swapping. In addition preferably the battery is covered for example with a flexible protective envelope, such as for example a preferably smooth surface and/or low friction surface which preferably contains inside for example a sponge and/or for example shock absorbing gel and/or other flexible and/or soft material.
Another possible variation is that, preferably in addition, for example before removing or inserting a battery preferably the swap device attaches itself to the relevant side of the car (for example if the battery is removed or inserted from the side or for 24/12/08 Yaron Mayer & Haim Gadassi 73/304 example to the back of the car if the battery is removed from the back), preferably for example by hooking itself firmly to appropriate protrusions ands/or canals and/or other structures for example in the relevant wall of the car, for example by using knits (i.e. preferably connectors which enter a hole or protrusion or tube and then expand for example by moving an additional element such as for example a hinge into them) and/or for example screws (but knits are more preferable since the connection can be closed and opened much faster and with less wear over time), and preferably these connections are made for example both sideways and up and down with preferably sufficient distance between the connection points to achieve stability, so that for example there is at least one connection to the right, one to the left one at the top and one at the bottom, for example with a distance of at least 1 meter between the side connections and preferably for example at least 1 meter between the top and bottom connections (or other reasonable distance) so that for example if the car or the relevant side of the car for example goes up or does or tilts due for example to weight changes and/or center of gravity shifts while removing or inserting batteries preferably the battery swap unit keeps the car stable and/or keeps the same relative orientation and/or height of the battery for example relative to the battery compartment and/or the car, since otherwise for example if the car tilts the battery might be scratched or bent, and preferably the swap unit has for example at least one back leg at further distance from the car (for example 1 meter or more or other reasonable distance) in order to increase stability even further. In addition, preferably the relevant parts of the chassis or walls of the car are for example especially reinforced for example at and/or between the positions of these knits and/or screws so that there is less possibility of the wall or chassis bending in these areas. Preferably the battery swap unit finds the positions of the for example knits or screw interfaces for example based on special mechanical and/or for example electronic and/or for example electromagnetic and/or for example optical markers and/or other markers which preferably mark their position, and/or for example based on a database and for example digital identification of the specific car type and/or model, as explained above, and/or for example by aid of one or more video cameras.
Preferably for example the robot for example first calculates the approximate positions of the for example knit and/or screw interfaces for example based on the database according to the car type and model and for example relative to the position of the battery compartments, and then preferably tries to find exact positions for example the through one or more video cameras that can for example identify the relevant protrusions and/or for example relevant colors and preferably these interfaces or protrusions are for example colored in a special colors which are preferably sufficiently different from the normal surface color of the car. In addition, preferably during the battery swap preferably the car computer automatically locks the car's brakes so that it does not accidentally move or slides during the swap, and/or preferably also automatically locks the car's shock absorption and/or suspension system in the same position in order to increase stability even more, and preferably also automatically does not allow the battery compartment to open before the engine is stopped and preferably the also does not allow the user to start or to try to start the engine again until the battery swap is complete and the battery compartment is closed again. Another possible variation is that for example during the battery swap preferably the car is for example automatically lifted for example by a platform below it for example by lifting the 24/12/08 Yaron Mayer & Haim Gadassi 74/304 lower part of the chassis for example even a small height of for example 5 or 10 or more centimeters so that for example the suspension system or for example the state of air in the wheels no longer creates movement up or down or tilting in the car for example due to weight changes and/or changes in the car's center of gravity (and/or for example in order to assist the lifting preferably there are for example special markings on the car for finding the best places in which to hold the chassis so that preferably there are for example moving vertical elements which can for example automatically move to these location before starting to lift the car) (and/or for example there is a device that comes down from above and presses the car downwards during the battery swap 'but that is much less preferable), and/or for example the car is stabilized during the battery swap by other means and/or for example the swap units attaches itself preferably firmly to the car during the battery swap by other means. (Preferably the attaching to the car for example with knits is preferably used at least in mobile swap units, for example when swapping batteries on the side of the road or for example in small or temporary swap stations for example in small settlements). Another possible variation is that preferably the car computer also displays for example on its monitor for example the progress of the battery swap and/or the expected time to finish, for example based on sensing and/or participating in various stages along the way, such as for example disconnecting the battery connectors, opening the compartment door, sensing that the battery has been removed, sensing the new battery is being inserted, connecting the new battery, etc., and preferably the computer also displays the exact charge difference between the depleted battery and the new battery, as explained elsewhere in this application.
Another possible variation is that for example the battery swap unit includes also a shock absorption and/or suspension system of its own for example in order to move more easily together with the movement up or down and/or tilting of the car, but that is less preferable since a more stable unit can also help more to stabilize the car, especially for example if the car's shock absorption and/or suspension system is automatically locked during the battery swap, as explained above. Another possible variation is that for example the fork arms have for example sensors that can sense their distance from the bottom and/or top and/or for example sides of the battery compartment so that the swap unit can balance the forks even better for example in the middle of the free space and/or for example in the same orientation of the compartment, for example by using mechanical switches and/or for example force-sensitive resistors (for example over the length of the arms or for example preferably at least at the top and bottom of the arms for example at various preferably small intervals of for example a few centimeters apart), and/or for example infrared and/or other sensors (since if the arms are below the battery the distance from the roof of the battery compartment is preferably sensed more remotely), or for example by inserting for example also for example a preferably thin strip for example with additional sensors for example also above the battery, so that for example the swap unit's computer automatically adjusts the height and/or sideways movement and/or orientation of the arms based also on these sensors.
Since, as explained above there might for example be different types of batteries and/or battery compartment types with different parameters such as for example different number or size of the canals or for example a different distance between them, preferably the fork arms can for example move for example not only up and down but for example also sideways for example together and/or relative to each 24/12/08 Yaron Mayer & Haim Gadassi 75/304 other and/or can for example also be extracted or contracted for example compared to the min body of the unit and/or the unit itself can move relative to the car as explained above, and/or for example the robot or human controlled swap unit contains for example a number of swap-able front end interfaces which can be preferably automatically changed for example according to the interface needed, and/or for example there are at least one or more different swap units or stations for example at least for some types of batteries or cars that for example require substantially different methods than for example most other cars or batteries.
In addition, at least if the swap unit is not manually controlled by a human operator (i.e. the unit is more autonomic), preferably the unit has various pressure sensors and/or for example video cameras and/or for example ultrasound sensors and/or other sensors that can preferably detect for example moving objects for example between the swap units or its arms and the car, so that for example if a kid or an animal moves and/or position itself between the car and the swap unit preferably the unit can automatically for example stop until the object moves away.
Preferably the battery has one or more sockets for example on the wall that is most far from the battery swap unit or for example on one of the sides or for example on the bottom, so that for example after it is secured in its position in the battery compartment, preferably a plug automatically comes into position for example through a preferably small hole in the wall or in the bottom of the battery compartment (which is preferably just a little bigger than the width of the plug). The socket can be also for example on the top part of the battery but that is less preferable since that could be a problem for example if it is raining while swapping the battery and for example rain enters the battery's socket from above. Another possible variation is that the socket is for example on the front side of the battery (i.e., the side that is most close to the battery swap unit) and for example the plug comes in from the front wall of the compartment when it is closed. Another possible variation is that for example the envelope of the battery preferably contains a preferably water-tight door which can be for example electronically opened or closed, or for example is opened mechanically automatically when the battery is fully inserted. In addition, preferably the battery compartment is preferably automatically ventilated in a way that draws away humidity, in order to reduce the chance for corrosion of the battery and/or for example there are humidity sensors for example in the space of the compartment which for example report to the car computer the level of humidity in the compartment. Another possible variation is that for example the swap unit has humidity sensors that can sense if it is raining or if the battery becomes wet can for example automatically wipe the water from the new battery for example with a special sponge before or while inserting it into the car, and/or for example the swap unit includes also a canopy that protects against the rain for example like a large umbrella, and/or for example at least in normal or stationary swap stations preferably the swap locations are preferably always for example below a preferably stationary canopy or roof so that preferably no rain can fall on the batteries during the swapping, but preferably the roof or canopy is transparent in order to give users a more familiar feeling more similar to the felling in a typical gas station and not for example like in an underground parking place where there is a roof above the car.
Preferably the battery swap units takes with it in advance the needed type of replacement battery and for example keeps it in a basket or open compartment on itself and after removing the depleted battery from the car the battery swap unit 24/12/08 Yaron Mayer & Haim Gadassi 76/304 preferably moves the removed battery for example on to a conveyor belt and for example takes the new battery from the basket or other storing place and inserts in the car, preferably while reversing the steps that were used for removing the battery, and/or for example the robot contains one or more conveyor belts on itself for example for moving the removed battery for example to one side and putting on the fork anns the charged battery for example from the other side, and/or as explained already elsewhere in this application preferably at least two conveyor belts pass preferably near each battery swap unit - for example one for the depleted batteries that are removed for the car and one for the ready charged batteries.
Preferably if for example the battery is for example later improved and becomes smaller, preferably it is made available for example also with an envelope that gives it a similar size and/or interface as the previous type of battery, so that for example older cars with the original larger compartment can still use it the same way and for example newer cars can be built with a smaller battery compartment that fits the new battery size.
Another possible variation is that for example the battery contains for example its own wheels or for example rollers, preferably in an intermitted way with gaps between them or for example the rollers at the bottom of the battery compartment are preferably intermittent or with gaps, so that preferably instead of through canals at the bottom of the battery and/or for example in addition to the canals, preferably the fork arms for example enter under the battery till the edge of the battery and then the arms are preferably moved up preferably with hooks at their edges, and thus preferably without having to pick up the battery it is preferably simply rolled by the arms outside while also resting on the arms, and the new battery is preferably again inserted the same way in reverse. This way preferably less precision is needed since the fork arms do not have to pick up the battery within the battery compartment, but preferably the robot still also attaches itself to the car and/or the car is preferably lifted up for example 10 centimeters by the chassis for added stability as explained above (Another possible variation is that for example after the battery compartment door is opened on one side of the car the charged battery is pushed in from that side and for example this causes the depleted battery to automatically come out on the other side of the car but, this is less preferable, since it means for example wasting more space for enabling these movements and/or for example having to use another swap unit also on the other side of the car). Another possible variation is that for example the battery compartment can for example be automatically moved by the car's computer for example forward or backward for example within a certain space (for example half a meter forwards or back again to the center, or other reasonable distance) - so that this can be used for example in order 'to help balance the car better if the user for example loads too much wait in the baggage at the back (preferably the weight is automatically measured for example by sensors that measure for example the average level of stress on the suspension system - for example mainly on the part that handles the back of the car. Another possible variation is that the car computer can for example automatically warn the driver for example not to exceed a certain speed (and/or for example limit the speed automatically) for example based on the load in the baggage and a database that shows the amount of danger of losing road grip for example in the front wheels as a function of speed and overload on the baggage, so that for example the computer recommends or temporarily limits the user for example to the maximum speed that can still be used safely with the excess weight in the baggage, and/or for example 24/12/08 Yaron Mayer & Haim Gadassi 77/304 the computer's warning is based on sensing automatically for example the hold that the front wheels have on the road for example when making turns. Another possible variation is that for example the car computer preferably automatically keeps logs of for example the number of turns or sharp turns which the user made with the car for example within the last minute and/or for example the last few minutes of driving and/or other reasonable time period preferably together with a speeds log for the same period or periods and can preferably automatically warn the user for example if the user is driving too fast for the number and/or sharpness of the turns -for example by comparing it with various relevant rules or database and/or for example also based for example on sensing also various parameters of the stability of the car on the road (such as for example the number of time the driver had to press the brakes sharply or for example the number of times the ABS has been activated)(preferably in this case the car computer says specifically to the user for example through synthesized speed or prerecorded messages for example that he/she is driving too fast for the number and/or sharpness of the curves and preferably also recommends the maximum speed for these conditions) and/or for example the computer can also warn the user similarly for example about other dangerous driving patterns and/or behaviors that are for example incompatible with the current speed. Preferably the battery swap units are for example also powered by electric batteries (for example at least the mobile units) or for example receive the electric power for example from a cable that comes from above, and for example in order to reach the correct side of the car preferably the unit can automatically for example travel around the car for example with a certain radius, for example freely on it own wheels (or for example on a round or elliptical track, in which case there is preferably also a straight track which for example moves together with the robot for example on the round track and then the straight track allows the robot to approach the car more closely from the round track and can preferably for example also rotate at a certain range of degrees and/or for example become longer or shorter as needed), and/or for example the car is for example on a rotate-able rectangle or circle, but the free wheels solution is more cheap and flexible. Another possible variation is that if the swap station for example temporarily does not have sufficient recharged batteries for example of a certain type then preferably the swap station can for example automatically reroute for example at least some of the batteries of that type for example to one of the fast rechargers in the station in order to have for example at least a certain reserve set of charged batteries of that type preferably as soon as possible. In addition, preferably the robotic swap units preferably have various protections against stealing them from the service station, so that for example they have a GPS or similar unit and are programmed to work only in the area of the service station and/or for example they receive wirelessly a short range special code for example every few minutes (or other reasonable period) for example from the service station's computer or for example from fixed devices near the battery swap post which is preferably encrypted and changing (so that it cannot be for example recorded and then repeated by the thief) and are preferably for example programmed for example to broadcast for example wirelessly their coordinates and/or shut themselves off automatically for example if they have not received the signal for example after a certain period, and this behavior is preferably embedded in their hardware. Another possible variation is that for example even with cars that don't come initially with swappable batteries preferably at least some 24/12/08 Yaron Mayer & Haim Gadassi 78/304 of them at least comply with some basic standards that enable for example at least replacing the battery for example after a few years for example with a more advanced battery - preferably for example at a car service garage which can preferably replace the battery preferably for example within for example 15 or minutes or less for example on a lift preferably without having to remove too many parts in order to reach it, or for example without the need to remove almost any parts since for example a faulty or leaking battery might for example require change anyway, so in fact it does not make sense at all to make it hard to replace the battery even due to this consideration. Another possible variation is that for example at least some for example electric cars that do not come initially with swappable batteries (i.e. for example the appropriate interface for enabling fast swapping at normal battery swap stations) preferably at least are designed in advance for example with an appropriate opening in the chassis for example below or on the side or at the back so that for example a proper battery chamber and/or unit and/or interface which enables battery swapping (for example of any of the types or variations described elsewhere in this application) can preferably be for example modularly added later (such cars can for example be called cars with preparation for battery swap), and/or for example in some such cars or for example in gasoline cars that were converted to become electric preferably the battery can be put for example in the baggage so that it occupies for example part of it, preferably together with an interface that makes it easier for the battery to be swapped for example by robotic arms when the baggage is open, so that for example the battery can be automatically connected or disconnected and preferably can be easily picked up for example from its sides, and/or for example at least in some types of cars for example a relatively flatter battery can be for example added preferably with swappable interface for example by welding and/or integrating a special additional compartment for example below the car so that for example the battery can be removed for example from the side or back of the new compartment (this can preferably be done for example when batteries with double power density become available, so that for example a 100 or 120 mile range battery for example weighs for example only 75 or 80 Kilograms and/or for example occupies only half the space of a 150 Kilogram battery).
But preferably all or for example most electric cars preferably come in advance with the appropriate interface that allows fast swapping in standard battery swap stations since with the proper chassis design the cost for adding the replacement interface is relatively low and since otherwise the user has a much more limited range and since otherwise it is harder or more expensive to replace for example a faulty battery, and since according to Shai Agassi batteries typically now double in capacity approximately every 5 years, so few people will want to be stuck with the same battery if a much improved model is for example expected within a few years.
Preferably if for example the car comes in advance with swappable batteries and the user is on a subscription plan in which the service provider owns the battery, and for example an improved or much improved and/or cheaper battery becomes available, preferably the service provider for example gradually replaces the batteries to the new type for example without extra costs to users for example by retiring the old batteries earlier for example for uses in homes and/or offices for example for enabling the users to pay cheaper rates at night and use the batteries at east partially during the day and/or for B2G services, as explained elsewhere in this application, and/or for example without even having to retire batteries earlier since normal 24/12/08 Yaron Mayer & Haim Gadassi 79/304 expansion of more and more electric cars being sold will preferably need also the new batteries anyway. So typically there will probably be for example after the first 2-3 years for example a constant situation where different generations or levels of batteries are circulating for example through the battery swap stations, and so preferably users can for example preferably get the more advanced batteries for example again based on their priorities and/or special needs at the moment, as explained already elsewhere in this application for example based on battery capacity, and/or for example at least for a certain intermediary period for example users that want to receive the more advanced batteries for example pay extra a certain amount for example in their subscription fees and/or for example users that don't need the new higher capacity batteries for example due to their typical daily mileage and/or agree to use the older batteries preferably get for example special discount and/or credit points and/or for example other bonuses. Of course, like other features of this invention various combinations of the above and/or other variations can also be used.

Another possible variation is that there are for example in at least some cities public private electric vehicles - which are for example electric cars which are for example owned for example by the service provider and/or by the state and/or by the city hall and/or for example by the electric company, so that the user can for example insert a smart card or similar device which includes for example his/her ID
and payment and/or credit and/or subscription data and can then drive for example to a destination within the city or even for example in another city, and then after the drive the user can leave the public car for example in one of the allowed parking places and preferably connect it to one of the rechargers or recharge posts so that it can be automatically recharged and/or so that another user can use it, thus reducing also the parking space problem (preferably the user is required to connect the public car to a recharger or recharge post when parking it and is for example reminded by auditory message if he/she forgets and/or for example cannot release his/her card until connecting the car to a recharger or recharge post and/or for example can be fined if he/she does not connect it). Preferably the smart card or similar device also automatically instructs the car computer for example to perform various adjustments, for example in the seats and/or in the mirrors and/or for example in the chosen sound simulations and/or volumes for example for various stages according to the user's individual profile (which can similarly be used for example similarly also for adjusting private cars for example for different family members, or for example in private cars the users can for example press one of a few buttons for example for using the values of the relevant family members, so that for example the buttons are programmed and used for example like station choosing buttons for example in a car radio). For setting the seats position preferably the car contains for example electrically moveable elements which can for example move the position of the car seats or can for example at least change the position of for example stops that limit the movement of the seat for example forwards or backwards at the desired position, so that for example the user simply has to push the seat for example back or forth so that it stops and snaps automatically into the desired position when it reaches the stop. Another possible variation is that the user can for example use a lever or similar control also for example for lowering the seat or for moving it higher (for example at least for the driver seat and/or for example also the 24/12/08 Yaron Mayer & Haim Gadassi 80/304 other front seat), and/or for example this can also be controlled for example by an electric motor which can move the control so that for example by choosing a certain profile or entering for example a smart card or other device the car can for example automatically move the seats up or down according to the desired user parameters (for example either of the two fronts seats or at least the driver's seat).
Another possible variation is that for example the drive wheel and/or for example the position of the drive lever and/or for example the stop lever can also be moved for example higher or lower or nearer or farther from the driver for example through a manual control and/or automatically for example with an electric motor (so that it can also preferably be remembered and automatically adjusted per driver).
Preferably when the user ends the drive he/she can for example release the car if he/she needs to park for a few hours, or for example can decide to keep it reserved for example for a few minutes or for example even an hour or more (for example 'if he/she needs to carry equipment to or from the car or get back to the car shortly), in which case preferably the user has to pay extra for example by money or credit points. In addition, the user can preferably also for example pay a special rate and hire the car also for example for a day or more, at the end again returning it to one of the allowed parking places. Preferably these public cars contain also for example one or more internal cameras which automatically photograph the state of the car for example internally and/or externally for example when the user takes the car and when she/she returns it so that for example damages can be identified automatically and attributed to the identified user, and/or for example these cameras can also be used for example to warn the user automatically for example by visual and/or auditory signal and/or for example by a message to his/her cell phone for example if he/she forgot something in the car for example on one of the seats or between the seats or for example in one of the compartments (for example based on computerized visual analysis of the images and/or for example automatic weight sensing). In addition, preferably these public cars contain a display of the state of the battery which is preferably clearly visible from the outside and/or also on an external display, and/or for example this is displayed clearly on the recharger or recharge post, so that users can preferably see instantly which such public cars are currently sufficiently recharged for their current needs. The public cars are preferably also automatically recharged according to the above explained parameters, so that for example while the car is reserved for the user it is preferably recharged according to the profile communicated by his/her card, like in normal electric private cars, and when such cards are returned to the public available pool preferably they are recharged for example according to global statistics or general statistics of the area (so that for example if approximately 70% of the people in general or in that area typically need only 40% battery power or more to go home for example from a working place, and for example 20% need 60% or more and for example 10% need a full or almost full battery, then the public electric cars at that place are preferably recharged automatically preferably based on the above statistics so that the system preferably tries first of all to create the needed distribution of available charge states and then preferably automatically tries to avoid recharging too much in the daytime or peak hours except for a certain preferably reserve safety margin). Another possible variation is that the system can also gather for example statistics according to the individual cards of the users which came with those cars, so that for example assuming that in a work place or shopping center or for example 24/12/08 Yaron Mayer & Haim Gadassi 81/304 movie center the same users will later leave with such cars, this can generate more accurate statistics for that more specific area and/or for that specific day or hours.
Another possible variation is that for example the above statistics and/or parameters, and/or for example data about public cars which have just been released by the user, can also be used for example for predicting in advance approximately when parking lots or recharge posts are about to become available even for example in congested areas where for example at certain times it is hard to find an available spot, so that preferably the system can for example transmit this information to drivers, who are searching for a parking lot and/or a recharge post, for example through a GPS device or cellular network.

Another possible variation is that for example (with normal cars or with electrical cars) in smart systems where parking meters automatically sense if they are vacant (for example by infrared or for example ultrasound or similar technologies or for example by using one or more metal wires for example underground or for example in a grove in the parking spot which carries for example an AC current and can detect for example by induction if there is a large metal mass near or above it) or occupied and can transfer this information automatically to drivers looking for parking and in which for example typically the driver can also extend the time in the meters from away for example through the cell phone (or for example even if there is no remote extension for example at least is some of the meters), preferably the system can also use the information about the remaining time in the meter and/or whether the driver has extended it to predict even more precisely when approximately it is about to become available and transmit this information to drivers who are looking for parking. Another possible variation is that for example once a nearby parking and/or for example recharging place becomes available and the driver gets an automatic notification that it is available preferably the driver can also order it in advance for example through the cell phone and start paying from that moment (preferably this is possible only if there is no car in the process of trying to enter the parking place before the order is fmished, as determined preferably by the local sensor), and then preferably the parking place is automatically marked as occupied or reserved, for example by a flashing for example red light or other preferably conspicuous visual indicator (such as for example an "occupied" or "reserved" or "do not park" sign which appears for example in the park meter's display, so that other drivers can see and understand it and so that for example if someone else enters and parks there after the order was made preferably a parking supervisor can easily see this and for example fine him/her) and preferably the parking place is preferably immediately automatically removed from the list of available parking places which is transmitted to drivers, and preferably the parking meter becomes automatically physically locked (for example mechanically and/or electronically) so that other drivers cannot enter money into it by mistake without noticing that it is reserved (and/or similarly for example if a recharging post is reserved, the recharger or recharge post preferably becomes automatically physically locked so that other drivers cannot connect to it or insert a card in it without noticing that it is reserved), and preferably when making the order and paying for it the driver gets a code and when that driver arrives at the parking place preferably he/she enters the code for example directly in the parking 24/12/08 Yaron Mayer & Haim Gadassi 82/304 meter or recharge post or for example through the cell phone or other gadget or device, and then the flashing light or other indicator preferably immediately stops and the driver can park there, and/or for example when the driver is within for example 10 meters from the parking place the system identifies automatically for example through his/her cell phone that he arrived and for example automatically calls him/her for example through his/her cell phone and lets him/her reply if to deactivate the flashing light or other indicator. However, preferably if someone for example orders a parking place and/or recharging place but does not arrive there for example within a certain time limit (such as for example 5 or 10 or 20 or 30 minutes or other reasonable time frame), preferably the parking place and/or recharging place becomes automatically available again and the driver who ordered it pays only until then and loses the reservation. Similarly, preferably if the driver can receive also for example a list of parking places and/or recharging that are not available yet but about to become available, then preferably he/she can also order for example a parking and/or recharging place which is not available yet, and then preferably as soon as it becomes available he/she preferably receives an automatic notification for example by an automatic call or for example SMS to his/her cell phone and then can for example complete the order. Another possible variation is that for example at least some parking meters and rechargers are united into the same device, so that for example the same pole (i.e. recharge posts with or without the actual recharging circuitry) is used for both of them, which can be done for example by including the electronics for both devices in the same device (for example when installing new parking meters or new rechargers), or for example by a deal between the recharge service provider and for example the city municipality, so that for example the recharge post or for example the service provider or the electric company (for example through direct cellular or other wireless communication between communication between the car's computer and their main computers) simply can charge the user also for the parking time for example at the same time as recharging and/or also while being parked there for example during the recharging and/or for example after the recharging has ended, and sharing the amount with the municipality (i.e. preferably transferring to the municipality the part from the total paid amount that covers the parking fee, for example with or without some commission to the service provider for providing the charging service for the parking part)(which means that preferably, for example as long as the municipality agrees, preferably every recharge post can function preferably by default also as a parking meter even without adding any additional hardware to it), preferably with at least some parking fee discount for electric cars in general and/or at least while recharging (even in the variations in which the car is recharged with an internal recharger this is no problem because as explained above even in these cases preferably both the car and the exact recharge post are preferably identified when the user connects the car to it for example by a digital link in the cable and/or for example by passing the smart card and/or credit card and/or other device and/or typing a password or secret code in the interface of the recharge post), and/or for example the car's computer can also communicate for this directly for example with the main computers of the municipality, while providing the location for example through GPS and/or for example cellular cells triangulation and/or for example through the communication with the recharge post which as explained elsewhere in this 'application preferably knows its exact location. The transfer of money to the _ _ , 24/12/08 Yaron Mayer & Haim Gadassi 83/304 municipality can be done for example at the time that the user connects or disconnects the cable or when he/she enters or leaves the parking place, or for example based on a monthly (or other period) report and/or balancing for example between the service provider and the municipality. However, in order to prevent inefficiency by parking near a recharger while not recharging and thus preventing another car that needs recharge from using it, preferably the recharge cable can be pulled for a distance of at least 2 cars or more so that one or more additional cars can use the recharger even when not directly near it, and/or for example there is a surcharge so that parking near a recharger while not recharging at least for example at rush hours or for example after a certain amount of minutes preferably costs more than parking at a normal parking place. Preferably for example as long as the cable is still connected during the recharge or for example even after the recharge has ended, preferably the recharger or recharge post or service provider automatically continues to calculate the parking time for example based on sensing that the cable is still connected, and for example if the user disconnects the cable or for example does not connect it at all but remains in the parking place then preferably the user has to pay by normal means, for example by entering coins in the combined device if the combined device contains such an option, or for example more preferably by passing for example the smart card or credit card or other device and/or typing the password or secret code in the user interface, and/or for example the service provider or recharge post can still charge the user also for the parking for example through wireless communication between the car and the recharge post or by using automatic sensors that can determine if the same car is still in the same parking place (for example by the same means that can determine if a parking lot is vacant or not, as explained above, so that preferably in this case the system also checks for example if the large metal mass has remained there all the time for example after disconnecting the cable or for example there has been a discontinuity which indicates that the car has moved out and than a car has moved in a again), and/or for example the car's computer for example through the cellular or other wireless direct communication (preferably digitally signed and encrypted) for example automatically notifies the service provider's main computers when the user has left the parking place (for example when the user starts to drive away for example for a distance of for example more than a few meters), and preferably the car's computer continues to send this message until receiving an acknowledgement from the service provider's main computers in order to prevent for example a situation in which the message has not been received for example due to bad communications and the service provider continues to charge the car for parking eventhough the car has already left the place, and/or for example the service provider's main computers for example automatically query the car's computer for example every few minutes or other reasonable time for example before extending the parking payments (for example if the recharge cable is no longer connected) (and/or preferably the service provider's main computers can also use for example sensors at least in sample places and/or for example the communications from the recharge post for example to find out if the car's automatic report does not fit the other data, for example if some hacker managed to temper with it for example despite the hardware encryption). However in order to indicate for example to parking inspectors and/or to the user that the parking is still being paid for and/or for example to prevent unauthorized cars for example from merely plugging a cable into the socket even if 24/12/08 Yaron Mayer & Haim Gadassi 84/304 they are for example not allowed to recharge or for example if the user has not entered the identification means for example at the user interface, preferably the recharge post or combined device automatically indicates for example by a different colored light and/or by other visual indication if the parking is being paid for (such as for example green light or other color if the parking is being paid for and for example red light if the parking is not being paid for, so that for example even if the cable has been inserted but the user has not identified himself/herself or the car or for example the car is not authorized to use that recharge post then preferably the light for example remains red). Preferably recharge posts that enable automatically paying also for the parking preferably have clear visual indicators that the recharge post serves also as a parking meter and/or takes care automatically also of the parking fee (such as for example by a special sign on the recharger and/or for example the special parking status lights, for example if some posts do not enable this), so that the user can know if he/she needs to worry about paying for the parking separately or not, and preferably the recharge post also has clear instructions about how to pay if the user for example is not connecting the cable or for example has disconnected it and remains in the parking spot (for example if there is no automatic sensing if the same car has remained in the parking spot) and/or for example warnings for example about special charges for example if a user occupies a recharge post but does not recharge the car or for example parks a non-electric car in that parking place (unless for example this is automatically prevented, as explained elsewhere in this application), and these messages are preferably displayed for example on signs or for example on the display screen, if the user interface contains a display screen. Preferably the recharge post (or for example the car computer or for example the service provider's main computers directly for example through the car's computer or through the recharge post) for example reminds the user preferably automatically for example according the local database of the recharge post or through communication with the service provider's database (for example with the car directly or through the recharge post, for example based on the time of day and/or the location and/or special rights of the car or the driver) if payment for parking is needed (preferably after asking the user approximately how long he/she intends to stay in that parking spot, which is equivalent to asking for example when the user intends to drive away with the car) and/or preferably asks the user explicitly (for example through its own user interface or through the user interface of the car's computer) if he/she wants to pay also for the parking automatically or wants for example to pay the municipality separately for example through other means, or for example has free parking rights for example in the area for example due to being a resident of the neighborhood, i.e. preferably even when charging the user automatically for parking preferably the recharge post (or for example the service provider's main computers directly) preferably reminds the user about having to pay for parking (for example at least if it is during hours in which parking has to be paid for) and preferably requests his/her authorization for paying also for parking.
Another possible variation is that for example free parking rights for example to neighborhood residents are automatically identified electronically, for example through the unique Id of the car, so that preferably for example the municipality automatically updates the service provider about free parking zones for specific cars for example based on car Id's (for example after the user makes the appropriate arrangement with the municipality), or for example through a smart card or other 24/12/08 Yaron Mayer & Haim Gadassi 85/304 physical device which the user can for example insert in some interface or reader in the car which is for example automatically read by the car's computer and can for example be automatically transferred to the recharge post or directly to the service provider for example with a preferably signed and encrypted digital certificate, or for example through the same smart card or other physical device which the user preferably passes in the recharge post (or for example in a reader in the car for example if the recharge cable contains also a data link, as explained elsewhere in this application) preferably when connecting to the recharge post, so that preferably at that time for example the recharge post also reads automatically from the smart card for example if the user has free parking rights and in which areas and knows automatically from its own coordinates if in is in a relevant area, and/or for example the service provider's main computers automatically transfer the unique car Id and preferably the parking times and the parking area for example to the main computers of the municipality (or for example to third party which manages collecting parking fees for them) and for example the main computers of the municipality automatically know according to their own Database for example if that car has free parking rights for example in that area and/or time period and for example automatically tell the service provider's main computers if and/or how much to charge the user and/or for example the municipality's computers can charge the user automatically directly for example through the credit card associated with the Id.
Anyway, the main advantage is that as explained above if the user agrees to pay for the parking through the service provider preferably for example the recharge post or the service provider (for example through direct communication between the recharge post and the municipality's main computer or for example through the main computers of the service provider or for example by simply automatically making the payment or the payment commitment and thus indicating for example through light on the recharge post that the payment has been made or is being taken care of) can preferably automatically extend the parking payment as needed, which means that preferably the user is for example automatically protected for example from having to plan in advance how much parking to pay for or from getting a report if he/she stays a longer time and forgets to extend the parking payment or for example from having to pay in advance in certain increments of for example a few minutes or more such as for example in units of a few minutes or for example 15 or 20 minutes or more or for example one hour or more in advance, etc., since preferably the service provider preferably enables automatically paying only for the exact time needed, and in addition preferably at least in some places and/or some time periods the service provider can make a deal with the municipality for lower parking rates for the end users for example based on the large scale operations of the service provider and/or its services for taking care of the parking payments and/or for example since as explained above the service provider preferably gets some commission from the municipality for taking care of the parking payments, preferably the service provider can share part of the commission with the user, thus offering lower parking rates than when paying directly to the municipality, and similarly for example taking care also for the parking means that preferably when the user reserves a recharge post preferably this enables for example the service provider's main computers also much more easily for example to reserve preferably automatically also the relevant parking spot and preferably indicate for example by appropriate flashing lights or for example other visual and/or for example auditory 24/12/08 Yaron Mayer & Haim Gadassi 86/304 indicator that the recharge spot and parking spot are currently reserved.
Another possible variation is that even if the user for example for some reason prefers to pay directly to the municipality not through the service provider, preferably the service provide can still protect the user for example in case the normal parking payment has ended and the user's car is for example still connected to the recharge post or for example is still parking in the same parking spot. This is preferably done for example by the user agreeing in advance for such "parking insurance" service (and/or for example by the service provider's main computers for example sending an automatic SMS or other communication for example to the user's cell phone or other phone for example reminding him/her that the parking payment is about to end or has ended and needs to be renewed and offering the service even if the user has for example not agreed to it yet in advance), so that for example if the user pays directly to the municipality preferably this is done through the car's computer or at least the user updates the car computer about the time until which parking is paid for, so that for example the car computer can automatically notify the service provider's main computer until which time the parking has been paid for, so that for example the service provider can automatically take care of extending the parking time if the paid-for parking time has passed, and/or for example if the covered parking time has passed and the user has not paid for an extension preferably for example the municipality's main computers for example automatically send for example a query to the service provider's main computers for example whether the car is still parked there and/or if the service provider wishes to automatically extend the payment for the parking - and then preferably if for example the user's car is still connected to the recharge post or for example by any of the other means described above the service provider's main computers determine that the user's car is still parked there, then preferably the service computer can automatically take over the parking payments (and/or for example the main computers of the service provider similarly for example automatically query the municipality's computers for example every few minutes or other reasonable time for example if the user's direct payment for the parking has been extended or not, but this variation is less preferable since it is less efficient), and/or for example if the car computer itself has been informed about the end time of the parking payment, for example the car computer can automatically contact for example the service provider's main computer and/or for example contact the user directly for example through cellular communication and for example remind him/her that the paid-for parking time is about to end and request instructions and/or for example if needed the main computers can for example contact the user for example through SMS or other cellular communication or for example email or IM or message on the web site, and/or for example the user can inquire about the remaining parking time_ for example through his/her cell phone and/or Internet communication and/or for example change parking related instructions this way. Another possible variation is that for example similar services (such as for example the automatic extension of parking time as needed) can also be offered for example by the municipality's main computers for example if the user for example chooses to pay directly to them, and in this case for example the sensing if the user's car is still in the parking place can be similarly done for example by sensors and/or for example by direct cellular communication between the car's computer and for example the municipality's main computers, or for example this is still done for example through the 24/12/08 Yaron Mayer & Haim Gadassi 87/304 communication with the service provider's main computers, and/or for example the service provider's main computers are at least used for example at least for checking if the user's car is still connected to the recharge post. Preferably if for example the free parking hours have arrived for example in the evening then preferably the automatic handling of checking and/or extending the parking time is automatically renewed for example only the next morning or the next time when paying for parking becomes relevant again. Another possible variation is that for example similar arrangements or deals exits for example also at least in some private parking lots for example between the service provider and the owner of the parking lot, for example in malls or hospitals in which the user has for example free parking for example only for one hour or for other limited time, or for example in private parking lots in which the parking is not free. In this case preferably for example if the parking requires payment but for unlimited time, preferably the user can for example pass his/her smart card or other physical device (for example the same device which the user preferably passes for example when connecting to the recharge post) for example through, a post at the entry to the parking place, so that the post preferably indicates visually and/or for example through lifting a block for example that the parking payment has been authorized and preferably can also print automatically for example a receipt for the user, and then preferably for example the service provider preferably charges the user automatically and transfers the payment to the parking lot owner, and if for example the payment is according to parking time then preferably the user can similarly for example pass his/her smart card or other device for example through a relevant post when entering the parking place and for example has to pass it again before exiting for example in a similar post for example in order to release an automatic block, and so when passing the card or other device again (or for example by similarly using for example an RFID
device for example at some distance) preferably the parking time is automatically calculated and if any amount is due for the parking time the user can be charged the proper amount by the service provider, and preferably these posts are located at the side of the car in a way that the user can access it without having to get out of the car, and preferably the user can also enter a password or secret code for example when passing the card or other device for example the first time or the second time or both, and/or for example the service provider preferably anyway automatically prevents payment for example if the for example smart card or for example the car has been reported (and preferably verified) as stolen and so can for example tell the post for example not to open the block in such case (preferably the post which is used for example when entering and/or when exiting the parking lot can be for example a normal recharge post which is preferably stripped of sockets and thus is used for example only for the user interface and the communication with the service provider's main computers). Another possible variation is that for example the car's license number is automatically photographed for example preferably when entering and preferably also when exiting the parking lot and then the number can be for example automatically interpreted for example by OCR, so that the parking time is preferably automatically calculated and the user is preferably charged for example directly by credit card or for example through the service provider, and/or for example the car's number is for example kept in a database for example in case of later complaints or disputes. Another possible variation is that for example the car has also for example a preferably two dimensional bar code or other easily 24/12/08 Yaron Mayer & Haim Gadassi 88/304 automatically readable optical mark which is preferably pasted for example from the inside of the front and/or back window. Another possible variation is that for example the user gets a paper or card for example with a time stamp for example from a guard when entering the parking lot, as usual in the prior art, and for example when going out for example passes his/her smart card for example through a relevant post or for example a guard keys-in for example the car's license number for example in a computer terminal in his/her post and so the guard is for example informed automatically if and how much the user has been charged for parking already for example by the service provider for example while recharging in the parking place, and so the guard can know if the user has paid in full or for example has to still pay a residual fee for the parking, but this is less preferable since the above variations of automatic payments or similar variations can be much more efficient and exact and require less human labor. Another possible variation is that for example the payment for example in such private parking lots can be similarly done for example by normal credit card or for example similar smart card or similar device which are unrelated to the service provider, so that the user for example simply passes his/her credit card or smart card or similar device for example through a similar post for example when entering the parking lot and preferably again when exiting, and preferably has to also key-in for example his/her secret code for example the first time or the second time or both, and then the user is for example charged automatically this way. In places where there are pre-existing parking meters, preferably the recharge posts, which preferably enable at least two cars to recharge from them at the same time, like parking meters, as explained elsewhere in this application, can be for example inserted for example between each two parking meters, or for example inserted next to the existing parking meter, in which case for example the user can pay for example either through the service provider or for example by using the old parking meter. Preferably if the recharge posts enable two cars to recharge at the same time, if parking is for example allowed on both sides of the street, preferably the positions of the recharge posts are preferably more or less parallel or substantially parallel on both sides of the street - since if for example there are actually two cars connected to every recharge post for example in a certain area of the street and if due to the cables people might be able to cross easily only between cars in the middle between the recharge posts and not between the cars near the recharge posts, preferably this way at least the same crossing point exists also more or less at the same position on the other side of the street. Preferably in such recharge posts preferably addition, preferably the parking spots are preferably for example marked on the street for example with rectangles so that for example the two adjacent for example rectangles or marked spaces are closer at the position of the recharge post and wider apart at the middle between the recharge posts and/or for example the distance between the recharge posts is designed so that it is sufficiently larger than the average or typical or maximum typical length of two preferably normal cars so that for example by naturally wanting to park as close as possible to the recharge posts the cars will usually be at a larger distance between them in the middle between the recharge posts. (This is also the advantage of for example the variations discussed elsewhere in this application where the cables for example come down from a higher pole or poles above recharge post for example into a socket in the car, since in such variations preferably pedestrians can also cross easily between cars near the recharge posts, however such variations have other 24/12/08 Yaron Mayer & Haim Gadassi 89/304 problems such as for example users who might bump into dangling spiral cables for example at night, so the cables in such variation preferably have to hang above the height of human heads - for example above two meters). Another possible variation is that for example at least in some places which have pre-existing parking meters, the service provider can for example have an agreement with the municipality so that for example the recharge post can be installed instead of the parking meter (so that for example the municipality can resell it or its pole for example for metal recycling or for example even sell the pole to the service provider), and then the service provider preferably must for example enable also any cars (i.e.
preferably also non-electric cars) to use it as a parking meter, for example by accepting credit card payments also from non-electric cars, or for example the service provider is allowed to cut off the head of the parking meter and weld it for example to the top of the recharge post, thus using the recharge post's pole also for the old parking meter, so that this way preferably the rechargers do not occupy more space in places that already had preexisting parking meters. Another possible variation is that for example in places where there are pre-existing parking meters the recharge post can for example be added on to a pre-existing parking meter, for example by adding to it an additional layer - for example on top of it, and/or for example by using a vertical extension to the existing pole for containing the wires. Another advantage is that preferably the payment for parking through the service provider is automatically extended preferably while the user is still parking there for example as long as the free parking hours have not been reached yet, thus protecting the user from having to pay a fine to the municipality for example due to insufficient parking payment, and preferably the user does not have to pay for example in units of for example 10 minutes or similar units as in prior art parking meters, since the service provider can preferably charge him/her for the exact number of minutes. Another possible variation is that preferably each recharge post preferably contains for example at least one preferably physical fuse which can automatically break the circuit for example in case of a short circuit (for example due to being deformed for example by a truck or for example due to some other malfunction), so that preferably such an event does not affect the functioning of its neighboring rechargers.

Another possible variation is that for example the car's computer can report to the user for example through the direct communication with the service provider's main computers or for example through a recharge post for example also general information such as for example what percent and/or what absolute number of recharge posts and/or parking places are currently available for example in specific areas, for example based on queries in which the user requests to find the areas with most available recharge posts and/or parking places and/or based on queries about specific areas which the user wants to check in advance (preferably based on automatic updates for example according to the sensors that can sense if a parking spot is available or not and/or for example based the automatic updates about the state of the recharge posts - for example by the recharge post itself or through cars that are recharging from them, and/or for example based on automatic communication for example between the service provider and parking areas where there is for example automatic counting of entering and exiting cars), and preferably for example the service provider's main computers can also for example automatically recommend to the user (preferably through the cellular or other 24/12/08 Yamn Mayer & Haim Gadassi 90/304 wireless communication with the car's computer) if for example due to the above situation it is recommended for example to reserve for example a recharge spot and/or a parking place in advance (preferably while taking into account the above data about the percent and/or absolute number of available parking spots and/or recharge posts in the relevant area and/or for example other statistics about the typical behavior in that area for example based on the time of day and/or for example which day it is in the week, etc.) and then the system can for example offer the user automa.tically to make the reservation and ask his/her confirmation.
Similarly, if for example a certain time has passed and the user has still not arrived at the relevant area and/or for example there is now more need for those places and/or for example the user has taken a turn in a different direction indicating for example that the user has apparently changed his/her mind, preferably for example the service provider's main computers can for example automatically tell the user that the preferably limited time reservation is about to expire and/or for example ask the user if indeed he/she has changed his/her mind and the reservation should be cancelled and/or for example automatically recommend to switch to an alternative reservation elsewhere. Another possible variation is that the car's computer can similarly for example report to the user automatically for example about traffic congestions and/or for example about where roads are most empty or in which the traffic is moving for example most smoothly - for example based on automatic updates by the car computers to the service provider for example about their current locations (for example based on GPS and/or on automatic triangulation by the near cellular cells) and/or their current speeds and/or current directions, and/or for example the user can request specific reports about the current traffic conditions for example in specific roads, and/or for example the user can similarly for example ask the main computers for example through the cars' computer for example how.
much time approximately it will take to reach a certain destination, for which the main computers preferably take into account the available routes and the current traffic conditions, for example assuming that the user will take a typical route to the destination or for example based on an automatically accumulated historic database of average time for getting there from the current position in general, preferably with appropriate adjustments according to the current traffic conditions or for example after the user has chosen a route for example through a GPS guidance module, so that for example the guidance module can also similarly answer such questions, or for example the car computer can automatically broadcast this data to the service provider's main computers, or for example the car computer can get the relevant traffic data from the main computers and can then use it to answer the user.
Another possible variation is that can for example the car's computer can display to the user (for example on a display and/or for example through synthesized speech) for example reports for example about the nature of specific problems, such as for example an accident in the road ahead - so that for example after one or more users report about a specific problem for example the service provider can send automatic updates at least for example to the relevant cars which are now in the relevant road for example up to a certain distance and headed in he relevant direction.
Another possible variation is that for example at least in the immediate area of the problem that is causing the road block - such as for example an accident or for example a stuck car or for example some other obstacle for example in at least one lane, preferably cars can for example automatically communicate between themselves for 24/12/08 Yaron Mayer & Haim Gadassi 91/304 example directly or for example through the service provider for example in order to automatically increase the efficiency and/or coordination between cars for example when passing the problematic spot, so that for example cars that have to change their lane at the problem spot merge with the traffic of other lanes more efficiently.
By doing this for example at the problem location the traffic in that location can preferably automatically start to move faster and thus affect for example the entire traffic jam without a need for additional such automatically improved coordination for example between cars further along the way, or for example the service provider's computers can also for example send a message at the same time to multiple cars in the line for example that they can now start moving faster, thus helping the effect of easing up the problem propagate faster. Another possible variation is that for example similar automatic reports are available for example to the car's computer for example through the service provider also for example about the current state of for example nearby battery swap stations, so that for example the user can know in advance for example how congested or free a certain battery swap station currently is and/or for example what is currently the average wait time for swapping the batteries in that station - so that for example the user can request and receive for example the current state of congestion in one or more specific battery swap stations and/or for example request information about the location and/or current state of nearby swap stations in which the wait time is currently most short, and/or for example information about the distance to swap stations with a certain wait time or below, and/or for example information about the number of currently available recharged batteries of the user's specific type for example at various nearby swap stations, and/or for example request the service provider's computers to automatically recommend for example the best choice based on taking into account automatically for example any of the above data, such as for example both the distance from the user's car current position and the current wait time in these swap stations, and/or preferably also based for example on automatic report by the car's computer about the current direction in which the user is driving and/or for example the current state of the car's batteries (since for example even if a certain swap station is for example closer but the user is for example driving on a highway in the opposite direction and for example has sufficient energy to reach a farther swap station which is in the current direction then going to the swap station which is in the correct direction is more preferable)(and/or also based also for example on various statistics or other relevant parameters about the car and/or the driver and/or for example on the driver reporting his/her specific destination) and/or for example automatic reports by the battery swap stations about their current states of congestion (for example based on automatically counting the number of entering and exiting cars and/or for example based on automatically calculating the current average waiting time for example by the computers in the swap station and automatically reporting such data for example through cellular communication for example to the service provider's main computers), and/or preferably for example the service provider's main computers can similarly use this data to decide for example if to automatically recommend for example saving in advance a place in the battery swap station, as explained above for parking places and/or recharge posts and/or for example to recommend to reserve and/or reserve for the user the specific type of battery that he/she needs. Another possible variation is that if there is for example a lack of sufficient batteries of a certain type in a certain swap station for 24/12/08 Yaron Mayer & Haim Gadassi 92/304 example due to an increase in the number of cars of a certain type that visit the station, preferably for example the station's computers can for example automatically order additional batteries of that type for example through their communication with the service provider's main computers. Preferably at least some or most of the automatic messages are for example by synthesized speech (and/or accompanied by appropriate visual display), and preferably the user's responses for example at least in case of Yes/No questions or for example in case of choosing an option in a menu represented as a numerical choice can be for example through automatic speech recognition (since at least differentiation between yes and no or between digits is already relatively easy an reliable technology), and/or for example the user can reply for example through one or more buttons for example on the steering wheel or nearby, so that for example a button on the right represents Yes and a button on the left represents No or vice versa, or for example at least some buttons can be moved in multiple directions or positions or states representing different functions or answers, and/or for example there are one or more track balls for example on the steering wheel or for example nearby so that for example turning the ball in different ways is like moving a mouse or for example like a multifunction button. Another possible variation is that for example at least some visual indications or displays can be for example presented to the driver for example by a projector which for example sits on the dashboard and for example includes automatic distortion correction for example pre-calculated to correct the distortion due to its angle so that for example it displays on the front glass for example text and/or images that are for example partially reflected back from the glass since the glass is not 100% transparent and/or for example the front glass is for example coated by a special layer that causes light from that angle for example to be even more reflected back, and preferably the image is also planned in advance for example to appear for example with a far away focus so that for example the driver can see it with the same focus used for viewing for example at least a few meters ahead on the road. Another possible variation is that for example data about the current position and/or speed and/or direction of traveling which are automatically reported for example by the cars' computers for example to the service provider's main computers can also be used for example for identifying the length of lines and/or waiting time for example in junctions and so can be used for example for real time updates for example from the service provider's computer for example to the computers of the authority that controls traffic lights, so that for example the traffic light can respond automatically at least to a certain extent according to this information, so that for example if the line of waiting car's and/or the waiting time for example from one direction is temporarily considerably longer than usual and/or for example the line of cars from another direction and/or the waiting time is for example considerably shorter then usual then for example the relevant traffic light or lights can preferably automatically adjust their priorities and/or cycles accordingly for example temporarily until the situation changes and/or for example till a certain time limit and/or for example until receiving remotely a different instruction, and/or for example this is done through various sensors on the road (such as for example based on infrared, ultrasound, induction, automatic visual analysis of images for example from one or more video cameras and/or similar sensing techniques), so that for example the sensors can report automatically for example to the main computers of the service provider or for example directly for 24/12/08 Yaron Mayer & Haim Gadassi 93/304 example to the computers of the relevant traffic light or lights for example through underground data wires and/or for example cellular or other wireless communication or for example to the computer or computers of the relevant traffic light authority and for example the traffic light computers can decide for example about such changes locally and/or can for example communicate automatically with the main computers of the relevant authority and request authorization for making changes. Of course similar infonnation and automatic updates can preferably be used also for example in normal gasoline or hybrid cars or other types of cars which are equipped for example with a smart user interface on the car's computer and/or GPS and/or cellular communication capabilities of the car's computer, and similar congestion information can preferably be automatically reported similarly for example about congestion and/or distance and/or location of near gas stations.
Another possible variation is that for example at least some private parking places preferably contain for example also one or more battery swap stations, such as for example in some malls or shopping centers or for example large trade fairs or for example some large work areas, and preferably at least some such places also enable the user to have the batteries replaced for example without having to waste time about it personally. This can be done for example by enabling the user to park the car for example on an automatically moving conveyor belt or similar automatic movement device, so that for example the cars on the belt or similar device are preferably moved automatically for example one after the other to the battery swap spot and after replacing their batteries are preferably for example dropped automatically from the belt or similar device for example when reaching a free parking place, and then preferably the car's final parking position can preferably be reported to the user automatically for example to his cell phone for example by any of the methods described elsewhere in this application for finding the location of a parked car, and/or for example by automatic triangulation through the cellular cells.
Another possible variation is that there are for example one or more workers of the place or for example of the service provider to which the user can give for example a special key or other device which preferably enables them for example to move the car for example only up to a certain distance and/or for example for a limited time and/or for example up to a certain speed, for example measured from the last location and/or time where the user for example removed the normal key and/or for example smart card or other device and/or for example parked or left the car, so that for example this key and/or other device cannot be used to steal the car and drive sway with it but preferably enables the worker to move the car to the nearby battery swap position and to enable accessing the batteries for swapping them and then moving the car to a final parking place, and then the worker can for example send the user a message through cellular communication about the final parking location of the car and/or the car can preferably be located for example by any of the automatic methods as explained above, and/or for example the worker writes the final parking location for example on a note which is placed together with the key and/or other physical device for example at a booth or counter where the user later comes to pick them up, and/or for example the workers send this information for example wirelessly to a one or more main computers (for example local or for example the service provider's main computers), so that it is available to the user for example when picking the key and/or other physical device. These variations can be especially useful for example if the user prefers or needs a battery swap instead of 24/12/08 Yaron Mayer & Haim Gadassi 94/304 normal recharging and plans to stay for a while in the area and for example there are some waiting lines for the battery swap. Another possible variation is that for example similar special keys or smart cards or for example other physical devices can be used for example to limit the speed and/or distance and/or length of time and/or times (for example in terms of range of allowed or forbidden hours) in which for example teenagers and/or for example employees or other users can use a car, so that for example parents or for example company car fleet managers or for example other owners or policy managers can give their kids or employees for example a special key and/or smart card and/or other device which for example sets different parameters for that user of the car than for example the normal use for example by the parent or for example the normal factory default (so that for example company management can decide that company cars should be limited in speed for example to 120Kph instead of the normal limit of for example 150Kph or for example that the recommended cruising speed is 90 and higher speed are allowed for example for only a certain percent of the time, and/or other values or parameters, for example if the workplace is paying for the energy, so that for example if the user exceeds the recommended speed to a certain extent and/or beyond a certain percent of the time preferably the car computer can for example warn him/her that continued use at such speeds will for example cause him/her to be charged extra, or for example a parent can program the smart card or other device so that for example the youth cannot exceed a certain speed at all and/or for example similarly issue automatic real time warnings and/or for example later reports for excessive or un-recommended speed, and/or for example in case of speeding beyond a certain limit for example the car computer can send the parent for example an automatic SMS
or other for example cellular communication for example in real time so that for example he/she can phone the youth for example immediately and scold him/her), and preferably the parent or owner can for example change these values or parameters for example through connecting for example the smart card (for example through USB or other interface) for example to the car's computer or for example to a normal PC, for example together with using for example a special password and/or for example connecting also his/her master key or smart card or other device, and so for example the parent can preferably for example program the smart card or key or other device of the kids so that for example when that device is used for driving the car preferably the car's computer can for example enforce a certain speed limit (such as for example 90 Kph) and/or for example limit the distance that can be traveled for example without entering a special extension code, and/or for example limit the time so that for example the youth will not be able to drive the car for example during certain hours in the night, and/or preferably if there is for example a time limit and/or distance limit (and preferably taking into account also for example the speed limit if it is relevant) preferably the car computer can also for example warn the driver for example in advance that for example continuing to drive beyond a certain distance or for example a certain time will not leave him/her sufficient time and/or distance to return, and/or for example in case of problems preferably the youth can for example phone the parent and get for example a special code then enables for example to continue driving beyond the distance or time limit for example in case the youth for example cannot not go back otherwise. Similarly, preferably the car computer can preferably for example automatically warn the user for example if there is insufficient energy to reach the user's destination, as 24/12/08 Yaron Mayer & Haim Gadassi 95/304 explained elsewhere in this application. Another possible variation is that since the car's computer can preferably for example keep and/or report for example automatically for example a log of automatic statistics for example about the typical speeds for example at least for a certain period, since this is preferably used also by the service provider for example to discourage wasteful driving, as explained elsewhere in this application, and/or for example these reports can be used for example by parents to check the driving behavior of their children and/or preferably the car computer can for example automatically draw their attention for example to dangerous or significant deviations for example through automatic cellular communication for example in real time or for example when viewing the reports afterwards, and/or for example a company that owns a fleet of cars can for example get for example from the service provider these statistics also for example for a group of cars, such as for example average speed statistics or reports for example across cars, and/or can for example automatically get for example a sorted list of most wasteful cars, and/or can for example request specific data about a specific car or sub-list of cars.

Another possible variation is that for example the car's computer can for example automatically change the position and/or orientation for example of the side mirrors for example based on the situation, so that for example when parking the mirrors can become automatically folded (i.e. for example the car computer does it automatically for example by default unless the user for example disables it, for example as soon as the user has moved the gear or drive control to the parking position or for example a few seconds or more afterwards or for example when the user turns off the car key or for example when the user removes the car key or for example when the user exits the car, and preferably the car computer similarly automatically restores the mirrors to the normal position before the driver starts to drive again - for example when the user moves the gear or drive control out of the parking position) (or for example the user can do it by pressing a button that does it from inside the car, but preferably even it this case preferably the mirrors are automatically returned to normal position for example when the user moves the gear or drive control out of the parking position as explained above) and/or for example when driving in reverse for example the car's computer can for example automatically change the position and/or orientation of the side mirrors so that they show for example a view closer and/or lower (such as for example near the area of the back wheels) for example in comparison to the farther view when driving forward, and preferably the user can for example adjust the desired orientation and/or position of the side mirrors for example manually for example for various situations and can then for example press a button that causes the car's computer to memorize this and choose for example in what situation to apply it (the movement itself it preferably accomplished for example by electrically movable hinges and/or arms which are moved for example by a small electric motor). Another possible variation is that for example if the user does not turn off the car headlights when turning of the car key for example instead of beeping and/or simply turning off the light automatically, preferably the car computer (for example at least in one of the available modes which the user can preferably choose) for example instead moves automatically for example into lower lights (which preferably use for example only 50% or 25% or less than the normal headlight power), and then for example the car 24/12/08 Yaron Mayer & Haim Gadassi 96/304 computer can preferably for example gradually fade out for example turn off the lights for example within the next minute or other reasonable period afterwards or for example after the user leaves the car. Another possible variation is that for example the car has lights sensors (such as for example by automatic computer analysis of the view from one or more video cameras) and/or for example ultrasound sensors and/or other sensors that can sense for example the shape of the terrain ahead and/or for example sense the range and/or shape and/or for example distance of the area covered by the front lights of the car or can for example sense if the car's lights appear for example substantially below or above their normal height in the field of view, so that for example if the car is on a certain plane but for example the road a few meters ahead for example starts going downhill or uphill preferably for example the car's computer can automatically for example tilt the front lights for example up or down (and/or for example sideways when needed) so as the compensate for example for a road ahead which starts to go up or down for example in front of the car and/or for example for other distortions and preferably keep the light on the ground at the normal distance from the car, so that for example if the road ahead starts to go uphill the lights preferably automatically move up and for example if the road ahead starts to go downhill preferably the lights automatically move down (and preferably of course the user can also disable such automatic adjustments), and/or for example the driver can preferably at least move the lights up or down manually for example by rotating or moving for example up or down for example a lever for example on the wheel or for example nearby for example on the dashboard (the movement of the lights is preferably accomplished for example by appropriate hinges which are preferably moved for example by an electric motor).
Another possible variation is that for example various keys and/or for example a trackball for communicating with the car's computer are located for example on the wheel. Another possible variation is that for example the automatic updates about the car's position and/or for example direction and/or for example speed of driving and/or for example destination can also be used for example for finding friends which are for example on a contactee list of the user, so that for example the car computer can notify the user automatically for example that a friend of his/her is nearby and/or for example is driving in the same direction, etc. Preferably like other features regarding the car at least some of these features can also be implemented for example also in normal gasoline or hybrid cars or other types of cars, for example if they have a similar advanced car computer and/or for example built-in internal cellular communication.

Another possible variation is that there are for example also multi-recharge posts so that for example the same recharge post preferably with the same computer and/or same user interface preferably has for example more than one preferably extendable cable (for example 2-5 or other convenient number, and/or for example each cable has more than one socket or connector or for example side branch, for example every few meters, so that more than one car can connect to the same cable at the same time) (for example based on a wheel which each cable or the cables are rolled around so that the wheel rotates when the user pulls the cable and preferably the cable returns when released for example based on a spring or springs or on automatic back rotation of a motor or motors which can rotate back the wheel or wheels), so that for example more than one car can recharge from the same 24/12/08 Yaron Mayer & Haim Gadassi 97/304 recharger or recharge post at the same time. This wheel or wheels are preferably on the outside of the recharger or recharge post, for example on horizontal hinges which are attached to it, since this way it is also for example easier to maintain them. However pulling the cables this way might be problematic since for example if the in-between car moves away in the mean time while the further car is recharging, for example people passing by might not notice the wire and trip over it, especially for example in dark hours. Therefore, preferably the cables are coated for example by an auto luminescent layer (such. as for example phosphor under a transparent coating or for example the same or similar material as those that exist in fireflies which glow for example in the air currents) and/or light reflector layer (for example of the same types or materials used in bicycles or in coats that reflect light in the night) and/or for example shiny or glowing colors and/or for example have flashing LEDs for example along the wire or for example every few cm or other reasonable interval which preferably for example get their power from the recharger or recharge post (preferably through a low current low voltage transformer or power supply in the recharge post) or for example from small induction currents around the wire (which is less preferable), so that preferably by walkers can also see them in the dark, and/or for example also small elements which rattle in the wind, such as for example thin for example plastic plates or rings, and/or for example proximity sensors which for example emit a sound for example if a person comes too close to the cable, and/or for example the cable is automatically lit at least at night or darkness hours for example by one or more horizontal lights that come out of the recharge post (which is preferably activated only at darkness or at the right hours and only if a cable is connected), and/or for example the recharge post is also itself for example lit for example by one or more lights or LEDs for example on the top and/or the sides at least at darkness hours (for example by pre-set times and/or by receiving instructions for example from the main computers of the service provider or of the electric company and/or for example by light sensors) and/or for example contains strips or elements of light reflecting materials and/or elements that glow in the night and/or shiny or glowing colors as explained above for example at least in places where there are insufficient lights at night - so that preferably people also don't bump into the recharge post itself for example in the night (This is important since unlike parking meters which are typically in central town areas where there are typically also street lights, the recharge posts might be located also on small streets where for example there might not be street lights)(If the cable for example comes out of the recharge post then preferably the cables have preferably the same right reflecting and/or glowing features as the cables that come out of the cars preferably have, for example in general or for example especially in places where there are insufficient lights at night). Preferably the recharge post can also automatically report for example to the service provider's main computers for example if there is a malfunction in the lights or LEDs (For example its own light or LEDS or for example light or LEDs on the cable, for example through the light sensor and/or for example through a current sensor or other electric circuit that can detect it) and preferably there are sufficient preferably small preferably low power lights so that the chance is very small for example that all of them will be for example burned at the same time. Another possible variation is that preferably users can for example pick or order the color of the cable (preferably from the same place or business that sell or leases them the car) for example like picking the color of the car preferably 24/12/08 Yaron Mayer & Haim Gadassi 98/304 independently from the color of the car (such as for example a red or white car with a bright green cable), and preferably for example if for example there is currently no car in stock which in the requested color which also has a cable of the desired color, preferably the cable or cables (for example if there are at least two cables in the car as explained elsewhere in this application) can preferably be switched preferably for example within a few minutes for example by opening a modular connection and/or for example replacing the compartment that houses the cable in the car, preferably in a modular fashion, preferably for example by opening some control within the car that enables then to replace it for example from the outside or for example opening some larger for or compartment in the car that enables accessing it. However in this case preferably the sets of allowed cable colors are preferably limited to only authorized colors, which are preferably bright colors and/or preferably also glow and/or reflect lights as explained above, so that by-walkers don't trip over them in the night.

Another possible variation is that for example the recharger or recharge post has for example one or more diagonal or vertical or for example upside-down-L-shape rotating arms or similar arms for example like fishing hooks, so that for example one or more such arms for example go upwards in the air from the recharger or recharge post and when rotated into the desired position another arm or for example the cable comes down to the car from above, thus avoiding the problem of people possibly tripping over a horizontal cable between the car and the racharger.
Another possible variation is that for example at least some rechargers or recharge posts are connected between each other for example with a horizontal bar for example at a height of for example 2.5 or 3 meters or other reasonable height and for example multiple cables which are for example wrapped around wheels (preferably with springs) on the horizontal bar can be for example pulled from above as needed (and/or for example the recharger or recharge post can for example automatically pull them down or up for example by rotating the wheels), and/or for example these cables are for example shaped like a spiral phone cord and can thus be flexibly stretched in the direction needed. In these solutions for example the preferable recharging at higher voltages has the advantage that the cable can be thinner and thus less heavy and easier to handle. Another possible variation is that for example at least some rechargers or recharge posts, for example at least in parking lots, have at least two short cables of for example up to 1.5 meters or for example 2.5 meters or other reasonable length, and for example at least two cars can park next to them, for example with their backs next to the recharger or recharge post, or for example when used in the street for example two such cars can park near the recharger or recharge post for example back to back from each other or for example the normal way by any of the solutions described below, so that for example each recharger or recharge post serves two cars, for example one behind it and one in front of it, like for example typical parking meters (and this is even more convenient if for example the rechargers or recharge posts serve also as parking meters, as explained elsewhere in this application). Another possible variation is that for example the electric car's socket is on the side more or less in the middle lengthwise, so that the more or less same length cable can come either from in front of the car or from the back of the car. Another possible variation is that the car has for example at least two useable sockets and/or cables, for example one in front and one at the back 24/12/08 Yaron Mayer & Haim Gadassi 99/304 (which are preferably both wired to the same place internally in the car)(which means that they can be for example on the side of the car near the front and near the back of the car or for example on the actual front and back or for example at the relevant corners, or any combinations of these), and the driver plugs the cable to the, nearest one based on the car's position relative to the recharger or recharge post (which is also much more useful for example if the same recharger or recharge post can support two cars, as explained above). Preferably if the cables and/or sockets are for example at the actual back and/or front part of the car or for example at the corners, preferably they are positioned sufficiently higher than the bumpers,.
and preferably the small door and chamber that contains each cable or socket and/or for example is preferably for example at least 1 mm or a few mm indented into the car and/or for example the frame that surrounds it is preferably especially reinforced, for example by a double fold in the chassis for example at 180 degrees or for example at 90 degrees, thus for example surrounding the chamber, in order to reduce the chance that the cable or socket compartment or it's small door might be damaged for example if the car gets a bump for example at the front or at the rear for example while parking. On the other hand if for example the cable is pulled out of the car and plugged into the recharger or recharge post (in which case the cable is preferably for example in some hollow preferably small compartment on the side of the car and is preferably accessed through a door that opens and closes), then preferably at least some rechargers or recharge posts have for example at least two sockets, and for example similar configurations can be used, so that for example the plug-in cable comes out from the side of the car preferably more or less in the middle lengthwise, and so the driver can for example plug the same length of cable for example into a recharger or recharge post in front of the car or into a recharger or recharge post at the back of the car, and/or for example the car has for example one cable near the front of the car and one near the back and the user can use either of them. Another possible variation is that for example the socket or the cable can be located for example on the side of the car within a certain range of possible positions, and the cable is preferably just a little shorter than the typical length of a car (for example up to 4 meters or other reasonable length), preferably in order to allow sufficient length but preferably prevent users from pulling a cable over the length of the next car to reach the recharger or recharge post, since as explained elsewhere in this application that could be dangerous since if the other car in the meantime pulls away someone might for example trip over the cable. However, the option of more than one socket or cable in the car is actually a more preferable variation since it is more difficult to position the cable or socket in the middle of the car lengthwise, and in addition, if the cable or socket is in the middle or for example if the socket or cable is in the back but in some situations the cable must be pulled to the front of the car (for example if there are rechargers or recharge posts for 2 or more cars at the same time or for example if the parking is perpendicular to the street and the recharger or recharge post is on the sidewalk and the user prefers to enter the parking place by driving forward instead of in reverse), this means that at least one door can become blocked by the cable, which can be inconvenient for example if the user prefers to first plug-in the cable and then for example take some things out of the car, or for example if the user remembers that he/she has to take something out of the car after he/she has already plugged the cable (although using for example cables in the shape of spiral phone cords as explained elsewhere in this 24/12/08 Yaron Mayer & Haim Gadassi 100/304 application can also help, this can still be a problem when the cable passes near the door, since even if the door can still be opened due to such cable's flexibility the user might for example trip on the cable). Another possible variation is that if there are for example at least two sockets or two cables in the car, the user can for example at least in some cases connect both of them at the same time for example to two separate rechargers or recharge post or for example to two separate sockets or two separate cables in the same recharger, thus for example enabling increased or double recharge speed (which means that preferably in this case the recharger or rechargers can automatically identify for example through the data link that this is a double connection and/or for example the car computer updates them accordingly, and then preferably they start issuing coordinated commands for example at the same time, or for example one recharger takes control of both connections, thus treating them for example as if it was a single higher power connection, or if the recharger is in the car then preferably the recharger can identify that the two cables are connected to sockets at the same time and thus draw more power, or for example the double connection automatically enables larger current, but preferably the recharger knows about this since this means for example that when getting instructions for example from the main computers of the service provider and/or the electric company it can preferably for example use double the amount which is allocated for example in the instructions to a single socket), but preferably this is allowed for example only if there is a sufficient number of unused other rechargers or recharge posts in the area at the time and/or if the car has sufficient priority or justified urgency, and/or for example the user is charged extra for example in money or in credit points for occupying two rechargers or two recharge connections at the same time. Another possible variation is that there are for example various hooks or supports for example above the doors or below them so that for example the user can put the cable over them so that it does not disturb opening the relevant door or doors while the cable is connected to the recharger or recharge post. If the cable or socket is for example at or near the middle of the car, preferably it is at the side near or at the top of the column that separates between the two doors, so that for example the cable comes out through a small side door at the top of the hollow column, and preferably the car doors have an appropriate inlet or socket in that area so that they do not cover the small side door and/or for example the doors have sufficient distance between their edges (and in this case preferably there are also for example hooks or for example a guideway above the doors so that the cable can stay above the relevant door for example when connecting to a recharger or recharge post in front of the car or behind the car). Another possible variation is that the socket or cable is for example on the roof of the car, for example in a small compartment which is coupled to the inner side on the roof and with a small door that opens above the roof, but that is less preferable since there might be for example problems of rain entering the compartment from above, so if such a solution is used then preferably the socket or cable for example comes out with a bend of for example 90 degrees or similar bend so that it is preferably more or less parallel to the roof or for example even bent by more then 90 degrees (for example by coming down from an elevation, so that for example the socket faces st least slightly downwards for example at an angle). Another possible variation is for example one or more sideways hooks which can hold the cable for example sideways away from the car doors, but this is also less preferable and someone might for example trip on the 24/12/08 Yaron Mayer & Haim Gadassi 101/304 hook or on the cable this way. In the variations in which the cable comes out of the car preferably the cable is on a wheel or reel for example inside the compartment or for example below it and the cable is preferably pulled back automatically when the user returns it, for example based on a spring like in a vaccum cleaner, or for example based on automatic electric movement of the wheel or reel or for example the compartment is large enough so that the user can simply fold the cable in it whichever way he/she likes before closing the preferably small door.
Preferably for example in parking lots similar rechargers or recharge posts can similarly support also for example 4 cars at the same time with 4 cables or 4 sockets, since if for example the recharger or recharge post is in the middle surrounded by 4 marked parking spots, it can recharge this way for example 4 cars that surround it.
Anyway, preferably the cable length or for example the arrangement of two or more available sockets or cables is sufficient so that preferably the user can recharge both if the cars park parallel to the road or for example at 90 degrees to the road or for example other in-between angle, and so that preferably the user can recharge both is he/she enters the parking place by driving forward or by reverse. Of course the side on which the socket or the cable is located on the car is preferably determined according to the side of driving in that country, so that for example in normal countries the socket or cable is preferably on the right side of the car, and for example in countries like England where people drive on the left side of the road the socket or cable is preferably on the left side of the car, however since as explained above the user might park in reverse, and/or for example since in one way streets there might be for example rechargers or recharge posts and parking places on both sides or the street, preferably the cable is long enough to reach the recharger or recharge post on the other side of the car (which should be no problem if the cable is for example 2.5 or 3 meters long, or for example each of the front and back cables are for example at least for example 2 or 2.5 meters long or similar length).
Another possible variation is that for example at least some cars have a socket and/or cable on both sides of the car, for example if in some situations it is more convenient for the driver to enter the parking place in reverse. Since various combinations of the above variations can also be used, this means of course that the car can also have for example one or more sockets or cables on one side and one or more on the other side, and/or for example at each location or some of the locations for example both a socket and a cable etc.. The advantage of having for example both a socket and a cable for example both at the front and at the rear of the car is that if the recharge cable or cables come out of the car, the cost for adding a socket near the cable if there is already a cable at that position is very cheap (since the internal circuitry has to exist already for the cable) and then for example the car can carry a normal cable which can be used for example for recharging at a speed of for example 3-4 hours or lower speed for full recharge (or other reasonable threshold which can preferably keep the cable thin enough), instead of heaving to carry a thick and heavy and less flexible cable that can be used also for high speed recharging, and then for example when connecting to normal wall sockets or to normal recharge posts the user preferably connects the car's cable to the normal socket or to a socket on the recharge post, and for example when connecting to a fast recharger, for example the heavier and thicker cable for fast recharge preferably comes for example from the high speed public recharger, and in that case the user for example uses preferably the nearest socket of the car, and preferably the high speed public recharger works 24/12/08 Yaron Mayer & Haim Gadassi 102/304 by disconnecting or overriding the car's internal recharger, as explained already elsewhere in this application. This also means that preferably if such a socket is used-for example only for high speed recharging, preferably it is by default connected directly to the batteries for example without even going through the car's internal recharger circuitry. Another possible variation is that for example even when connecting to a high speed recharge post the car can for example still use its own recharger and for example the high speed recharge post provides also an improved heat dissipation system, so that for example the car's internal recharger has for example an external heat exchange interface, which can be connected for example to a larger radiator and/or for example liquid cooling system in the high speed recharge post or, however this is less preferable since a high speed recharger in the car would need also considerably more expensive electronics. On the other hand, if the batteries are recharged at considerably higher voltages, for example by more serial routing at least during high speed high voltage recharging, and/or by using higher voltages also during operation, such as for example 500 volts or more or for example 750 volts or more or for example 1000 Volts or more or other reasonable high voltage, then the cable might be thin enough so that preferably a more or less normal thickness cable can also be used for high speed recharging and/or for example the high speed recharger circuitry is also cheaper since it does not have to deal with high current, as explained already elsewhere in this application.
Another possible variation is that for example one of the two cables (or sockets) in the car comes out of the actual front side of the car (for example between the headlights and/or above or below them) and one from the actual back side of the car preferably for example near the sideways middle of these sides, thus maintaining even more easily also the symmetry between the two sides of the car. Another possible variation is that for example if at least some cars have a socket and for example the rechargers or recharge post network is based on rechargers or recharge posts with sockets instead of cables, or for example most rechargers or recharge posts have a cable but there are some rechragers that only have a socket, preferably the user can buy a male-male cable which preferably comes with the same standard plug interface and can thus connect between the two sockets, and is preferably for example normally located in the baggage and can be taken out and used when needed (and in such case preferably both plugs are preferably automatically locked and/or can be automatically released for example by the car and/or by the recharge post and/or can preferably also be released for example by a command from the service provider's main computers and/or cannot be released by an unauthorized person and/or can only be released by the car's user, for example unless the lock has been released automatically, preferably in the same way as a single plug, as explained elsewhere in this application). Another possible variation is that for example at least some electric cars have for example both a socket and a cable at least in some of the positions for example if they need to work in different areas with different standards, however that is less preferable and preferably the authorities enforce a single standard in each country (i.e. for example only the car has sockets and the rechargers or recharge posts have the cables, or vice versa). In addition, preferably in the recharge areas and/or for example in periodic messages for example by the government and/or for example by the service provider users are warned not to connect cables in a way that might block another car or jump over another car for example in a way that for example if the other car moves someone 24/12/08 Yaron Mayer & Haim Gadassi 103/304 might for example trip on the cable, and preferably city hall inspectors fine drivers if they discover a cable connected in such an irresponsible way. Another possible variation is that for example also in normal gasoline or Diesel cars or for example in Hybrid cars or plug-in hybrid cars preferably also the fuel tank can be accessed from both sides of the car (preferably left and right), for example by leaving the full container on one side and a adding an additional small fuel-loading door and interface also on the other side of the car preferably with an internal pipe that leads to the fuel container, and/or for example by using a container which is elongated and thus reaches both sides, and/or for example by putting the container more or less in the middle sideways, so that a short pipe can lead to it from each side. This has the advantage that for example when standing in line in normal oil refilling stations the user can for example choose between left-side pups and right-side pumps, instead of the prior art of having to stand in line only for the available side that fits the side of the fuel-insertion interface his car, even if the other line is shorter or empty (which can be important for example on peak days and hours when many people come to refuel their cars at the same time) - for example on Friday mornings in Israel. In this case, preferably the user has in the car for example a separate switch for unlocking from inside the car the right fuel insertion door or the left fuel insertion door as needed (or for example the same switch can be turned left or right accordingly) but preferably for example a single action can automatically lock both of them.
Another possible variation is that for example like with the electric recharge cable, preferably the car's computer preferably warns the user and/or prevents the user for example if the user tries to start driving for example if the refuel hose has not been removed or the fuel-door has not been closed.

Another possible variation is that there are for example at least some rechargers or recharge posts in which there are for example multiple cables (for example preferably at least 2-5 such cables from each recharger) that come out from one recharger and are connected for example through underground tubes to various for example smaller posts or outlets which come out for example near adjacent parking places near the recharger or recharge post, so that for example one or more additional parking places for example at each side can be hooked directly to the same recharger or recharge post through one of these cables without extending the cable in a way that people can trip over it between the car and the recharger or recharge post. (In these subsidiary posts preferably the cable that comes out of the preferably hollow underground tube is preferably secured firmly for example to the concrete or to the bottom of the pole and from there preferably goes up with some free slack, so that for example the this free part of the cable preferably has for example a length of 1.5 meters or other reasonable length, so that for example the plug an the end of the cable normally rests for example on some hook at the top of the pole, and for connecting it to the car the user preferably merely removes the plug from the hook and connects it to the car socket, and for example before or after this the user has to for example pass his/her smart card for example through the control panel at the main post, or for example there is a separate slot for passing for example the smart card also at the subsidiary post but for example the main logic and control is run by the main post that controls said subsidiary posts), and/or for example if a cable that contains also a data link is used and/or for example if the car's computer communicates directly with the service provider's main computers 24/12/08 Yamn Mayer & Haim Gadassi 104/304 preferably the user can for example pass the smart card and/or enter a password or code for example through the car's computer and/or use the car computer's monitor also as the user interface for talking with the recharge post. In addition, preferably if the car's recharger or computer can communicate directly for example through cellular or other wireless communication for example with the main computers of the service provider and/or of the electric company, preferably for example when connecting for example with a cable that contains a data-link for example with a recharger or recharge post or outlet that has its own direct communication with the main computers preferably for example the main computers or the recharger or recharge post or outlet can instruct for example the car's computer or the car's recharger to stop the direct communication with the main computers and accept the instructions directly from the recharger or recharge post or outlet, or for example the main computers can tell the recharger or recharge post or outlet for example to temporarily stop sending instructions to the car's computer or recharger and let them -receive direct instructions from the main computers, and preferably the car's computer or recharger and/or the external recharger or recharge post or outlet are able to act according to such instructions. On the other hand if for example the cable comes out of the car and is connected into a socket on the recharger or recharge post, then for example if such subsidiary posts are used, this means that for example the subsidiary posts, for example like the main post, each have for example one or more sockets, but for example the user interface and/or main controllers are for example on the main recharger or recharge post (in case of passive recharge posts these controllers in the main post can be for example one or more processors, sensors, communication unit, backup battery, etc.). Another advantage of using subsidiary posts is that preferably for example only the main recharger has to take care of heat dissipation. Another possible variation is that for example when starting to put rechargers or recharge posts for example at various intervals for example in the street or parking lot, preferably at least some rechargers or recharge posts are designed in advance in a modular and/or redundant way that enables for example adding additional rechargers or recharge posts for example by connecting underground to the existing rechargers or recharge post or to existing underground interface for example instead of having to connect for example to a central source in the area (for example for the power and/or data connections). This is preferably done for example by creating for example at least in some places stubs or stems or interfaces preferably underground in advance in places where future rechargers or recharge posts can be added, so that for example the underground interface contains for example an electrical interface (for example socket or for example closed cables to which a socket can be added), preferably a data interface (for example socket) and preferably also a' heat exchange for example in the shape of a radiator (for example if there is a fluid underground cooling system for example where there are high speed rechargeres), and is preferably for example in a pre-dug preferably vertical hole and covered for example with a lead, or for example the underground hole is covered for example with the normal pavement and hidden but the service provider has detailed maps which allow it to locate the exact spot and/or uses hidden marks, so that when needed it can later open the exact location, and preferably with adequate protections so that criminals cannot piratically interface with it -for example by containing an embedded underground digital identifier, so that the network preferably does not supply any electric power and/or actual data access to 24/12/08 Yaron Mayer & Haim Gadassi 105/304 nodes that are not yet officially activated (for example through underground switch) and/or for example as explained elsewhere in this application anyway preferably only a valid recharger or recharge post with the proper id and encryption can communicate with the network. This way preferably when the service provider or for example the electric company installs the recharges and has to dig underground anyway even if installing only a few interspersed rechargers or recharge posts at the beginning (thus saving costs initially), preferably the underground work is already ready also for adding the additional rechargers or recharge posts later, so as electric cars start to be sold and the infrastructure service provider starts to have an income it can gradually add additional rechargers or recharge posts as needed with almost no installation costs, since there is preferably no need to dig again horizontally for example under the pavement or install again the underground network or the interface. In this case preferably the recharger also has the matching heat exchange interface at its bottom which goes underground and preferably the electronic circuits and chips that control the recharging are also there near the heat exchange, so that for example the part that protrudes above the ground is preferably for example just a pole with one or more sockets (or cables) and/or for example a display and the user interface. Such a modular interface has the further advantage that for example if a recharger or recharge post is malfunctioning or needs service preferably for example the technician can for example remove it preferably easily and quickly from the modular interface, insert another proper recharger or recharge post in its place, and take the malfunctioning recharger or recharge post for testing and/or service at the service provider's facilities. Another possible variation is that such underground modular interface is also used for preferably almost instant temporary insertion and removal of rechargers or recharge posts instead of using mobile rechargers or recharge posts for example in tourist towns where there are for example large fluctuation in the number of people during the year, as explained elsewhere in this application. On the other hand, another possible variation is that for example after inserting a recharger or recharge post into the underground interface it is preferably welded into position, so that preferably it becomes even harder physically to steal, preferably in addition the electronic and network defenses as explained elsewhere in this application for preventing theft of mobile rechargers or recharge posts.
Of course if the heat dispersion is above ground for example through a radiator and fans in the air or for example it is a recharge post which does not contains its own recharge circuitry (i.e. for example an electric power interface for cars that use their own internal recharger for recharging) then the underground heat exchange is not needed, but if for example some of the recharge posts contain their recharge circuitry and use the underground heat exchange and some not then preferably the underground interface contains the heat exchange anyway, and for example if a certain recharge post does not contain the recharger circuitry or for example uses only its own above ground heat dispersion, then that post might come for example without a matching heat exchange, or for example such a post comes with a mock-up element that fits mechanically into the underground heat exchange for example for additional mechanical stability eventhough it does not actually function as a heat exchange. Another possible variation is that since, as explained elsewhere in this application, preferably most recharge posts are passive and the heat exchange with a cooling underground system is preferably used for example only when needed for example for high speed rechargers, preferably for example an underground heat 24/12/08 Yaron Mayer & Haim Gadassi 106/304 exchange is only added with the post when needed without a pre-existing lower part heat exchange at the bottom. Anyway, preferably the underground modular interface can preferably also be used for dynamically changing for example the dispersion of various types of rechargers or recharge posts, so that for example the service provider might start for example with more power transfer posts without their own recharger circuitry and a few normal external rechargers, and after some time for example preferably easily replace some of the types for example with pother types -for example with normal external rechargers, or for example replace them or normal external rechargers for example with high speed rechargers, or other similar switches as needed. (Of course for example some high speed rechargers might for example used both the underground heat exchange and an additional heat dispersion unit above ground).

Another possible variation is that since high speed rechargers (which can for example charge a car to full or almost full capacity for example within a few minutes or for example one hour or less) might be for example more expensive since they need higher power and/or for example better cooling, preferably the service provider for example spreads for example in various places such as for example the street or parking lot for example a certain desired mix of for example high speed and normal speed recharges (and/or for example also additional levels), so that preferably the percentages are based on need statistics, so that for example if really high speed rechargers are needed for example only 20% or less of the time or for example are usually needed by only 20% or less of the electric cars, preferably for example 80% of the rechargers or recharge posts are normal and 20% are high speed rechargers (or other reasonable division), and preferably there is a clear preferably visually conspicuous indication near the recharger or recharge post about its type, and preferably cars can also be for example automatically directed for example to normal or high speed rechargers based on their needs (for example by cellular or wireless Internet communication between the car's computer and the central computer and/or for example the rechargers), and preferably for example if a user connects to a high speed recharger despite being directed to a normal speed recharger or recharge post, there can be for example extra charge or debit points involved. In addition, preferably when connecting to high speed rechargers which can for example fully recharge a car with fast batteries for example within an hour or half hour or similar short time or even shorter time, preferably the user is required to remove his/her car away from the high speed recharger for example after a certain reasonable time (for example within an hour or for example within 10-30 minutes of the end of the recharge or other reasonable time after the end of the recharge, or for example quicker if he/she for example remains in the car during the recharge, and preferably this is in terms of time from the end of the recharge, since for example various load distribution considerations might cause the recharger to work only part of the time for example at its full capacity, thus taking longer to recharge for example compared to its optimum ability), otherwise for example he/she preferably has to pay extra for example by money or by debit or credit points for not allowing someone else to use the fast recharger, at least for example if there is a shortage of rechargers or recharge posts or of high speed rechargers for example at that time and/or area. Another possible variation is that preferably the rechargers or recharge posts are designed in a modular way so that for example a normal recharger or 24/12/08 Yaron Mayer & Haim Gadassi 107/304 recharge post can be easily upgraded to a high speed recharger for example by adding to it for example the appropriate circuitry and/or one or more additional power supply lines (preferably for example by adding a connection to additional power cables which for example already pass by below it for example next to the original power cable and/or for example be logically routing additional power to it) and/or for example by adding to it a stronger heat dissipation element.
Another possible variation is that for example preferably while installing the rechargers or recharge posts or for example at least high speed rechargers, which preferably have the power cables laid underground, preferably the service provider installs also a preferably underground liquid cooling system so that for example oil or water (preferably with an antifreeze element in cold areas) or for example another liquid moves through pipes (for example durable plastic pipes of the same type that are used for conducting drinking water in the city) which preferably for example interact with a heat sink or heat exchange for example underground at the bottom of the recharger, and these pipes preferably carry the heat for example to a nearby heat dissipation unit (which can be for example with a preferably large heat think, fans, and/or preferably air conditioning system, and can be for example on a large pole or for example in a room for example in a parking lot), so that preferably multiple rechargers (such as for example 10 or 20 or other reasonable number) are served preferably by the same pipes and preferably the same heat dissipation unit.
This can have the advantage that heat can be dissipated more efficiently without unduly increasing the size of individual rechargers, and the further advantage that for example high speed rechargers can preferably more easily be deployed dynamically for example in full power or partial power, so that for example if not all of the rechargers in the group are currently connected to cars or for example if some of them are currently recharging at low speed, the rechargers that are connected or some of them can for example work closer to their maximum capacity since the aggregate heat of the group is still below maximum. In addition preferably the heat dissipation unit and/or for example rechargres that have their own heat dissipation unit preferably also have for example automatic sensors that can sense for example if the heat dissipation or for example air flow for example is no longer efficient, for example due to accumulation of dust or other problems, and can then preferably for example use automatic brushes or for example automatic air or water cleaning and/or for example send an automatic alert for example to the service provider's computer requesting for example service by a company's technician. Similarly, if underground liquid cooling is used, preferably the system can also automatically issue warnings for example to the service provider's main computers, for example if leaks in the cooling liquid are detected, for example by using sensors that can determine the height of the liquid in the tubes. Of course if all or most of the public rechargers or recharge posts are passive, i.e. without the actual recharger circuitry, and/or for example there are only a few fast recharge posts which contain fast rechargers then installing an underground liquid cooling system might be a waste of money.

Another possible variation is that for example at least some rechargers or at least some high speed rechargers are based for example on using the natural cycles of the electric network in order to transmit pulses into the battery (or for example super capacitor), thus preferably saving on the circuitry and preferably reaching higher 24/12/08 Yaron Mayer & Haim Gadassi 108/304 recharge efficiency, which can be for example even 95% or more or even 99%
instead of for example 90% with normal on-off switching, which means less waste of energy and also less problems of heat dispersion and for example cheaper and/or smaller heat sinks, so that preferably the recharger of course still decides what power and when to transfer to the battery in general according to the battery's characteristics and/or behavior and preferably according to the various statistics and/or parameters and priorities and/or various changes in the network and/or in nearby rechargers and/or instructions from the main computers of the service provider or the electric company, as explained above, but preferably the normal sequence of fast pulses is done or replaced through using the natural cycles (instead of for example changing the pulse width when creating the DC in normal rechargers). This is preferably done for example by using coils with a stepdown controller and/or a synchronized rectifier and/or similar elements, so that for example a certain amount of current is accumulated each time and then discharged automatically into the battery before reaching the coil's maximum capacity.
However such recharging is preferably enabled only when using sufficiently fast batteries which can handle the spikes in current that can be created this way, so that for example such rechargers have a special socket (or plug) and only users of compatible batteries are provided with appropriate cables (or sockets) (or for example if the recharger is in the car then for example only compatible types of batteries can be physically inserted, or for example the recharger can also handle slower batteries for example by reducing the current or for example by emulating the behavior of normal rechargers), and/or for example the batteries preferably transmit digitally also their type (which includes preferably for example the manufacturer, preferably the exact model, and/or various other parameters, such as for example year of manufacture and/or for example the maximum current and/or voltage and/or peaks that can be handled during recharge, as explained also above) so that the recharger knows according to these parameters if they are compatible, and/or also for example the recharger checks their behaviors for example all the time or at short intervals and preferably stops preferably immediately or for example uses a different recharge method if the behavior indicates that the batteries are not responding properly to this recharge method. Another possible variation is that preferably the recharger can also use for example different slices of the wave form for recharging more efficiently for example different elements at different voltages, so that for example the recharger can access separately for example separate elements or groups of elements in the battery, so that for example some groups contain more elements and some groups contain less elements in a way that creates for example a sequence of groups, for example at various levels of voltage until for example 380 volts (or for example other convenient voltage that can be supplied by the electric company), so that preferably each slice of the wave cycle is routed for recharging for example the element or the elements that have closer voltage or for example the closest voltage to the voltage of that slice, thus creating a smaller voltage gap and creating more stability in the pulses and/or even further optimization and efficiency. Preferably similar methods can be used also for example when recharging multiple batteries or groups of batteries for example in the battery swap stations (i.e. for example by using different group sizes and fitting the slices of the wave forms according to the group size, preferably by similar multiplexers), preferably with higher voltages and preferably together with serial 24/12/08 Yaron Mayer & Haim Gadassi 109/304 recharge of preferably more or less homogenous groups of batteries, as explained above. Another possible variation is that for example instead of using fast pulses in order to reduce the size of the magnetic core in the transformer and/or in order to control the current by changing the pulse-width of the DC wave form, preferably at least some rechargers use instead for example a considerably larger core which preferably works at the natural cycle of the electric company and preferably contains for example a slot or a hole or for example some other cavity and preferably a moving element which can be automatically moved in or out of the slot or hole or other hollow space to the desired degree as needed (for example by a small electric engine controlled by the recharger's processor), thus controlling for example the voltage and/or the current in a way that reduces or increases the efficiency of the core and thus can change the current as needed preferably without wasting the energy, for example in a way similar to the way in which such a type of core is used for example in at least some welders. This means that such a recharger can be for example 20-30% larger than a normal recharger of the same capacity and can weight for example 80 or 90 Kilograms instead of for example 10 Kilograms due to the heavier core but can reach much higher efficiency, such as for example around 99% instead of for example around 90%, and in addition the price of the recharger can be significantly lower due to less and/or cheaper components needed.
So even when used for the internal car recharger this can be beneficial despite the increased weight due to the much higher possible recharge efficiency, and/or for example if used at least for high speed rechargers, which are typically outside of cars, the benefits can be even bigger because then weight and size are a less important consideration and the higher efficiency and cheaper components are much more important, since otherwise high speed rechargers which can for example fully recharge the car batteries for example in 30 or 60 minutes can cost for example 10 times more than a normal recharger which can for example fully recharge the car batteries for example in 4 or 6 hours, and otherwise such a high speed recharger would need a large and expensive heat dispersion unit, as explained elsewhere in this application. Similarly, this can be even more beneficial for example in battery swap stations, for example if larger rechargers of this type are used for example to serially recharge groups of batteries at higher voltages, as explained elsewhere in this application, since again in such stations size and weight are much less a consideration than for a recharger inside a car, and reaching a much higher recharge efficiency is much more important, thus both saving energy and reducing the need for large and expensive heat dispersion or cooling systems. As explained also elsewhere in the application preferably these serial rechargers can for example recharge serially three 380 volt car batteries for example at around 1140 volt or for example 26 such batteries for example at around 10,000 volt or for example an intermediary number - and preferably at least some of them are designed to work at the same high voltage of the electric company's high power lines, thus avoiding also energy losses due to voltage conversion, and similarly preferahly at least some of them can offer for example B2G services also directly at such high voltages, as explained elsewhere in this application. Preferably battery swap station which use serial rechargers preferably have various spreads of serial recharges which are pre-designed or optimized to work for example with a different group size of batteries and/or for example at least some rechargers which can handle for example a variable group-size of batteries preferably together of course with changing the voltage 24/12/08 Yaron Mayer & Haim Gadassi 110/304 accordingly. Of course, like the other features of this invention, various combinations of the above and/or other variations can also be used.

Another possible variation is that preferably at least in the beginning at least in some areas preferably the service provider deploys at least partially mobile rechargers or recharge posts which can be easily moved from place to place, so that for example in remote areas that for example have a small population and have for example a large number of tourists for example only a few months a year (such as for example Eilat in Israel), the service provider can for example increase the number of rechargers or recharge posts during the rush season and then for example transfer them temporarily to other places for a few months. This is preferably done for example by creating high power outlets for example in various centers to which multiple rechargers or recharge posts can be hooked up or for example by enabling hooking such mobile rechargers or recharge posts for example to the main electricity room for example in apartment buildings or hotels. In addition, preferably rechargers or recharge posts are also controlled for example by a special code which they have to receive and respond to from the main computers for example every hour or every day or other reasonable period, so that if a recharger or recharge post for example is stolen or relocated without permission preferably the main computers can discover this within this period, and preferably the recharger or recharge post itself is programmed to shut itself down and/or refuse to work if for example a certain time has passed and it did not get the proper periodic authorization code from the main computers, and this behavior is preferably embedded in its hardware, and/or for example the recharger or recharge post has a GPS or similar unit and for example can receive from the main computers a command that allows them to work only for example within certain coordinates.

Another possible variation is that the user can similarly also for example request to reserve a public car in advance, preferably in a way similar to the way described above for reserving parking places, for example through cell phone or for example through a normal phone call or through the Internet or similar network, and preferably the user can for example get to his/her cell phone or for example through the web site for example indicators about where the nearest public cars are which currently have a certain amount of charge energy or above (for example by requesting cars with 60% battery charge or more or for example cars which are 90%
or more fully recharged, or for example cars with sufficient energy to drive a certain desired distance), and preferably the reserved car preferably becomes temporarily locked (for example for up to 15 minutes or other reasonable period) and with a preferably conspicuous visual indicator that it is currently reserved, and preferably if the reserving user does not come to take the car within the allowed time limit preferably he/she looses the reservation and/or for example is charged a fine for reserving the car without coming on time. Preferably the parking and/or recharger or recharge post reservation system and the public car reservation systems are connected, since for example reserving a public car indicates that at the same time its parking place and/or recharge post will become available to other users -typically for example within a few minutes.

24/12/08 Yaron Mayer & Haim Gadassi 111/304 Another possible variation is that if for example a driver gets stuck in the middle of the road with an empty battery (for example on a highway between towns), preferably he/she can call for example through the cell phone for example a battery service, which preferably sends one or more trucks which are preferably related to the nearest service station and/or for example are part of the for example service provider network to which preferably most drivers have a monthly subscription (or for example are subcontractors of the service provider or for example are otherwise related to the service provider or authorized by the service provider), so that preferably each truck can carry for example 10 or more complete sets of replacement batteries (i.e. for example for 10 or more cars), and preferably the truck includes also the mechanical device for replacing the car batteries, so that preferably it can reach the car within a reasonable short time and can preferably replace its battery or batteries for example within a few minutes at the side of the road or for example recharge its battery or batteries for example at least temporarily with sufficient energy to reach the nearest service station and/or for example the truck contains for example high power capacitors (or other quick recharge energy sources as explained above) which can be used to recharge the car's batteries in a short time, for example if the car has M 1 batteries or similar or other fast charge batteries or other fast recharge devices such as for example one or more super capacitors such as for example EEStor, as explained above, and/or for example the truck can use one or more or a set of Ml batteries or similar or other fast charge batteries or other fast recharge devices such as for example one or more super capacitors such as for example EEStor which it carries also for fast recharging of the car's batteries or for example super capacitor, if the car also has such batteries or super capacitors or other fast recharge devices, so that for example within a few minutes the car's batteries can be recharged for example to 80% or similar capacity or most of its capacity, as explained above (or for example to full capacity with 12-15 minutes, or for example the recharge is still less for example due to less than optimal conditions, but still preferably a recharge of preferably a few minutes is preferably sufficient preferably to drive for at least another 20-30 niinutes or other reasonable time or distance so that for example the driver can reach the nearest battery swap station), and preferably when recharging, preferably both the car's batteries and the batteries on the truck are preferably automatically switched to a more serial connection so that the recharge is done at higher voltage, as explained above. (So preferably fast recharging of the car's batteries is the preferred choice, and replacing is preferably done for example if the car has normal non-fast batteries or for example there is some malfunction in the car's batteries, and preferably the same batteries or for example super capacitors which the truck carries can be used either for fast recharging or for replacing the car's batteries or for example super capacitor). (Like in the other types of rechrging, preferably the recharge for example from the fast batteries or for example super capacitor can be done for example by using the car's internal recharger if the car has an internal recharger, or for example by using a high speed recharger which is on the truck or for example similarly in service stations that enable such fast recharge for example from other batteries or super-capacitors or similar storage devices, but using a special recharger located on the truck is more preferable since such a rechrager preferably uses directly the DC energy from the batteries or for example super capacitor of the truck to create the DC pulses for recharghing directly the car's batteries, which is preferably done by initiating a 24/12/08 Yaron Mayer & Haim Gadassi 112/304 command which disconnects the car's internal recharger and allows the external recharger to access directly the car's batteries, as explained also elsewhere in this application, whereas using the car's recharger would normally mean having to convert the DC to AC and then to DC again. Another possible variation is that for example the car's internal recharger can be switched into a mode in which it circumvents the AC input and can take DC input for example directly into the units which in the normal mode get the DC after conversion, however this is still less preferable since it would mean either slower recharge time or that the car's recharger would have to be a high speed recharger, which can be considerably more expensive than a normal recharger). Preferably if the user is a member of the service for example based on some monthly subscription the service of the service truck is done for free or for example for only some partial or symbolic fee. Preferably the service truck is sufficiently narrow and contains sufficiently long connecting cables (and/or for example sufficiently long robotic arms for replacing batteries, and/or for example the mechanical battery replacement system is a modular separate unit which is for example lowered from the track and moved closer. to the car), so that it can preferably park on the side margin of the road for example in front of or behind the car, so that while recharging or swapping batteries it does not disturb the normal traffic. Since this mobile unit is preferably human-controlled as explained also elsewhere in this application and/or can be for example shaped like or based for example on a preferably small fork-lift vehicle (especially if the battery is for example moves horizontally for example through the back of the car), unlike the preferably automated or more automatic robotic units which can each for example swap the batteries of cars in swap stations for example automatically in about minutes, it can be for example much cheaper a s much simpler than the automated robotic units at the swap station. However, this human controlled mobile battery swap unit can for example still have at least some automatic elements when interacting with the battery, so that for example after the human controller for example points the arms for example at the direction of the batteries or for example inserts them below the batteries and/or for example issues a command which activates for example horizontal rollers inside the car that for example help push the battery in or out, preferably the mobile unit can for example handle more automatically the extraction of the batteries from that stage and/or similarly the insertion of the new batteries afterwards. Another possible variation is for example at least some service trucks both carry batteries and/or the battery replacement device and preferably can also carry or tow the car itself like a normal tow service if needed, so that for example, if it turns out that the malfunction is in the car itself and not in the batteries, the same service truck can also carry or tow the car for example to the nearest service station or to an appropriate electric car garage without having to send a separate truck for that, and/or for example the arm that can pick up the car for towing it can also be used for example for lifting the car at least partially while replacing the battery or batteries so that for example the robotic arm that replaces the batteries can for example have an easier access. Another possible variation is that preferably the battery replacement and/or recharge service stations or at least some of them or at least for example most of the big ones preferably contain also a service garage for electrical cars so that it can also solve for example other mechanical and/or electrical problems which the car might have. Another possible variation is that the car has also for example an internal connector which enables 24/12/08 Yaron Mayer & Haim Gadassi 113/304 plugging-in for example a temporary emergency battery (or batteries) which is preferably smaller and lighter than the normal electrical car batteries but preferably is sufficient for example for traveling for example for at least 20 or 30 minutes or other reasonable time or distance, so that the car can for example reach the nearest service station (i.e. for example battery swap station or for example fast recharge post) or for example a near recharge post or for example the user's home, and then preferably the car temporarily takes its energy from this temporary battery instead of the normal batteries. Preferably the service truck can also for example supply the car with such a temporary smaller battery (for example if the user does not have at least one emergency battery or for example if the user has also used up the emergency battery or batteries, in which case this is preferably done as a battery swap, which is especially useful for example if the emergency battery or batteries are also preferably typically owned by the service provider), and/or for example the car preferably carries one for example in the baggage for example in a special compartment within it or for example below it, for example like carrying a~
spare wheel (but preferably even if it is below the baggage it is preferably in a locked compartment and is preferably also protected by a special digital Id and/or password against stealing) and/or for example such emergency batteries are for example on a compartment for example on the front side of the car for example below the engine and thus can be for example moved in and out for example horizontally for example from the front or from the side for example in a way similar to the way that the main power battery is preferably moved, and/or for example the service truck can also charge for example the car's emergency battery if it is empty, which is preferably also for example an Ml or similar or other fast charge battery or other fast recharge devices such as for example one or more super capacitors such as for example EEStor. Preferably the smaller emergency battery or batteries are considered standard equipment and preferably the car computer also warns the user for example if he/she is traveling without at least one emergency battery or for example if there is a problem that prevents normal recharge of the emergency battery or batteries or for example if an emergency battery is leaking charge or for example has other problems. In addition, preferably the user can also for example swap the emergency battery or batteries or for example at least one of them for example also manually for example in various places which are authorized by the service provider, such as for example post office branches, various shops, etc., and preferably such swapping also involves testing the swapped batteries for current charge so that the difference between the user's emergency battery's current charge and the new battery is calculated and preferably automatically broadcast to the main computers of the service provider, and/or for example such emergency or reserve batteries can preferably for example swapped by mobile robotic devices which are preferably much smaller and cheaper then the robotics at the swap stations. The small emergency battery (or batteries) can preferably be connected for example through the baggage itself or for example by putting it for example on the back seat or for example on the floor between the front and back seats, but preferably it is normally connected all the time, so that it is preferably also charged automatically for example when the normal main battery or batteries are being recharged - for example directly by the same recharger or for example through the normal batteries (for example through the same preferable power supply which can also for example recharge the small front battery which preferably powers for example the car's 24/12/08 Yaron Mayer & Haim Gadassi 114/304 computer and/or displays as explained elsewhere in this application). Of course, if as explained elsewhere is this application, the main power batteries are also composed for example of two or more separate modules or elements which can be swapped separately, this can also make it easier for the service track to swap for example at least one of the modules without the need for heavy robotics like for example in the swap station. Another possible variation is that for example the user can request help from passing by drivers and preferably the driver that helps him/her canfor example tell his/her car's computer for example exactly how much power to transfer to the other car and then the recharge preferably stops automatically when the amount is reached, and preferably at least if the drivers are members of the same monthly subscription service or network, the helping driver can preferably get automatically credit points from the service provider for example by authorizing the transfer and credit in advance or confirming the transfer afterwards for example through cellular phone, so that for example he/she is entitled for extra credit since his help saves the need to send a service truck, and/or for example the recharging car's computer can also display automatically the estimated cost of the energy so that if for example the helping driver charges the user's batteries with 25%
of a full recharge (so that he/she can for example travel another 50 Km or other reasonable distance), and then the driver that received the help can for example pay him/her.
Preferably the above described truck service is part of the general service received automatically by subscribers of the network of service stations.

Another possible variation is that preferably the display in front of the driver in the car preferably includes also information about how full the battery is (preferably in percentages) and/or how much capacity the battery still has (since for example batteries that are a few years old might gradually lose for example up to 10%
of their capacity) and/or preferably for example how much time it would take to recharge it for example to full state for example with an average normal public recharger or recharge post and/or with the recharger or recharge post at home, and/or for example how much distance approximately can still be traveled for example until the battery has to be recharged or replaced (preferably while taking into account also the average speed of the car for example in the last N
minutes or seconds or other period or for example the exact current speed, which is preferably computed automatically by the car's computer which preferably also keeps an automatic log of the speed in the desired time window, and/or for example the inclination of the road, i.e. if the car is climbing or going downhill or moving in a more or less horizontal plane, and/or for example by automatically sensing the current weight in the car, for example because of carrying more passenger or load, for example by an automatic digital scale at the bottom of the chassis), and/or for example how far and/or where is the next closest battery replacement service, and/or for example how far and/or where are the closest rechargers or recharge posts or fast rechargers (preferably based on automatic information for example through a cellular network or GPS), and/or for example the driver can request for example to see separately the location of faster than normal rechargers, and/or for example additional parameters of the battery, such as for example its condition, age, number of recharges it had already gone through, and/or other parameters which are preferably available automatically preferably as digital information from the battery's computer, as explained above. Similarly, when recharging at a specific 24/12/08 Yaron Mayer & Haim Gadassi 115/304 .

recharger or recharge post preferably the recharger or recharge post communicates digitally with the car's computer so that the computer preferably displays to the driver automatically for example according to the car's statistics and/or parameters and/or according to the load at that time in the area and/or according to the voltage or power of the recharger and/or based on the state of the battery -preferably an automatic estimate of the predicted recharge time, which preferably is more specific and accurate than the general estimate which is not based on a particular recharger or recharge post. In addition, preferably while the car is recharging the user can for example send queries for example through his/her cell phone for example to the central computers (i.e. for example the service provider's main computers) which are preferably in contact with the rechargers or recharge posts for example through transferring data through the electricity lines as explained above or for example through a cellular network or for example wimax or similar network or for example other preferably Internet connection (This is preferably done for example by logging in to the service provider's web site for example with the car's Id and/or registration number and/or the user's Id or login and preferably also password and/or for example by being identified through his/her cell phone number for example when connecting with the cell phone or for example when using the cell phone number for the login, as explained also elsewhere is this application, and/or for example through SMS or other communication for example when connecting through the cell phone, as explained also elsewhere in this application, and/or for example the user can for example from his/her celiphone or for example from a regular phone for example get the information from an automatic voice menu from the service provider's main computers, for example by keying-in the car's license number and/or for example unique id and preferably also a secret code) (and/or for example send the queries directly to the recharger or recharge post for example if it contains for example a cell phone and/or for example similar communication for example directly to his/her car, i.e. remotely, or of course locally for example if the user is in the car) and can preferably query for example how full the battery already is and/or for example how much average traveling distance is now available and/or for example if the charge is now enough for example to reach a certain destination for example with a certain safety margin (for answering this preferably for example the main computers take into account the current location of the car and also for example approximately how much of the trip would be downhill or uphill) and/or for example how much time is needed to complete the recharge (i.e. for example till full recharge or till the recharge plan is complete - i.e. the intended amount of current recharge, as explained also elsewhere in this application), and/or for example the user can be notified automatically for example through SMS or other communication for example to his cell phone and/or for example by email or Instant message when the recharge is complete (i.e. for example if the battery is full or for example if the current recharge plan is complete) or for example at various stages, such as for example when a certain percent of recharge is complete (such as for example 75%
or 80%) or for example when the recharge has become sufficient for example for driving to a certain destination, or for example when some other requested condition has been met, or for example when other events happen. Similarly preferably the user is preferably warned in a similar way automatically (for example by SMS
or instant message or automatic phone call for example from the service provider's main computers and/or for example directly from the car's computer) if for example 24/12/08 Yaron Mayer & Haim Gadassi 116/304 somehow the cable has become disconnected and/or for example especially for example if according to the car's computer the car is being moved by someone (for example at least if the user is logged in at the service provider's web site at the time for example through another location or for example the location of his/her cell phone for example according to automatic cell triangulation is away from the car when this happens, which can mean that the car is being stolen) (eventhough as explained elsewhere in this application the cable is supposed to be locked automatically at least while the recharge or recharge plan has not completed) and/or for example if there is some other problem with the recharging or for example some other important problem that requires attention. Similarly preferably the user can for example see on the service provider's web site for example also for example the general state of recharging of electric cars for example in general for example in the country or for example in the same general area or for example in the same street or parking lot - for example in order to see the status of his/her car for example in comparison to other cars, including for example his/her priority scores for example compared to the other cars in the area or other cars in general. Another possible variation is that for example at least some recharge posts contain for example also a webcam or similar device so that the user can for example see through the web site for example upon request also a real time video feed of his/her car for example while connected to the recharge post (in such case, in order to save bandwidth, preferably images are only sent for example at certain intervals and preferably for example only upon request so that for example the main computers instruct the recharge post to send the images to the main computers only if the user has requested it). In addition, if the user for example feels that his/her car's priorities in general are for example too low or unjustified preferably the user can for example file a request for correction for example through the web site and/or through the phone preferably together with the reasons (this is preferably in addition for example for special requests based for example on specific upcoming needs, as explained elsewhere in this application, in which the user can preferably for example request for example immediate temporal maximum priority for example if something has come up that requires now as much recharge as possible as soon as possible). In addition preferably the user can for example see for example through the internet and/or cell phone and/or for example on the car's computer monitor for example maps of areas where there are recharge posts or concentrations of recharge posts, for example in general or for example in specific areas, and/or for example by clicking on concentrations and/or for example by saying or typing-in specific areas such as for example cities and/or neighborhoods and/or street names and/or numbers the user can preferably for example zoom in and see additional details.
Another possible variation is that for example the driver can type-in a desired destination for example in the GPS device and then preferably it can communicate also with the car's computer or for example directly with the battery (for example through wire or bluetooth or UWB), and/or for example the user can type it in the car's computer or for example choose it for example from a pre-exiting menu for example through voice commands, and so for example the GPS device or the car's computer can preferably tell the driver automatically for example if he/she has sufficient battery power to reach the destination (preferably while taking into account both the distance and how much of the trip is for example downhill or uphill, as explained also elsewhere in this application) and/or for example can automatically recommend 24/12/08 Yaron Mayer & Haim Gadassi 117/304 to the driver for example not to exceed a certain speed (such as for example 60 or 70 or 80 Km/H or other calculated speed for example in which the air resistance is lower) in order to conserve sufficient energy to get there without need for recharge or battery swap on the way (preferably the car computer recommends to the user automatically for example also for example regularly even when there is enough charge in the battery for example not to exceed normally the recommended speed of for example 80 or 90 Km/h - which is preferably for example the recommended speed for not reaching too high air resistance and preferably the speed of optimal efficiency for the engine as explained also elsewhere in this application), and/or for example if there is insufficient energy to reach the destination or for example it is a borderline case or for example unclear if the energy will be sufficient, preferably the car computer can for example automatically recommend to the user for example to go to the near battery swap station preferably while choosing the swap station which is preferably in the current driving direction and is preferably still within reach of current charge of the battery, as explained also elsewhere in this application, or for example if even that is too far for example to go to a nearby fast recharger or to a nearby normal recharger preferably while also pointing out preferably the exact place of the swap station or recharge post for example on a map as explained also elsewhere in this application. Similarly preferably even if the user has not explicitly entered a destination, preferably the car computer (and/or for example the service provider's main computers) can for example automatically guess the user's destination for example based on his/her usual destinations and/or other drive patterns and/or current position (for example based on GPS and/or cell-phone cell triangulation) and/or direction (and/or can for example preferably ask the user to confirm the assumed destination or for example to choose it from an automatically displayed menu which is preferably automatically generated by the car's computer for example based on the typical usual destinations of the car and/or the driver, so that for example the user can pick the option number through voice communication or can for example even say the name of the destination so that the automatic speech recognition can for example choose the most similar sounding destination and/or preferably ask for example a yes or no to confirm), and/or for example if the user is currently on a highway for example based on finding (for example through interfacing with the user's GPS navigation system) for example that there are for example no normal exits for example from the current highway for example for the next N miles, and/or for example based on finding that after the near battery swap station for example there are no additional swap stations and/or for example no recharge posts or fast recharge posts for example for a distance which is insufficient to reach with the current state of charge (preferably based on the computer's database of available battery swap stations and recharge posts, which is preferably automatically updated preferably regularly from the service provider's main computers and/or for example is also automatically updated for example with additional details, such as for example about the available local recharge posts and/or fast rechargers for example when entering or nearing a for example a specific general area, and preferably based also on taking into account for example the percent of the way which is uphill or downhill, as explained also elsewhere in this application), so that for example if there is insufficient charge for example to reach the nearest guessed destination or for example the nearest highway exit or for example the nearest other swap station (or for example other recharge option) for 24/12/08 Yaron Mayer & Haim Gadassi 118/304 example after the near upcoming swap station, preferably the car computer (and/or for example the service provider's main computers preferably through the car computer) can for example automatically bring to the user's attention that he/she will probably or for example certainly or for example almost certainly need to stop at the near battery swap station on the way and can preferably alert the user for example as soon as the computer realizes the problem and/or for example at least a few minutes in advance before reaching the near battery swap station that he/she should prepare to go to the station to swap the battery or batteries, preferably with additional automatic reminders as the user is nearing the battery swap station, for example unless the user indicates clearly that he/she does not want to go to the swap station for example in reply to a question by the computer (for example if the user is on a hurry and for example has a spare emergency smaller battery for example in the baggage or for example in a special compartment for this, which can be used for a certain additional distance for example through simply plugging it for example with a cable inside the car for example even without having to remove it from its position). Preferably the car computer (and/or for example the service provider's main computers) warns the user for example about the need to go to the nearest swap station preferably while disregarding the additional extra mileage which is available from the smaller emergency battery or batteries, since the emergency battery is preferably used only as a last resort for example in case of error.
Another possible variation is that the for example car computer (and/or for example the service provider's main computers) takes into account at least in some cases also the extra mileage available from the emergency battery or batteries and can for example recommend to the driver to use it - but preferably only for example if it is need just for a short missing distance - for example if using also the emergency battery will allow the user for example to reach a far swap station which is a little more far than the nearest swap station but is more in the user's exact direction than for example the nearest swap station. These alerts are preferably done for example by automatic synthesized speech and/or for example by flashing a for example red light which indicates danger of running out of energy and/or for example other visual and/or auditory indicators. As explained also elsewhere in this application, since at least some of these types of information are needed also for other features described in this application, for this preferably the car's computer and/or for example the GPS
or similar guidance system preferably for example contain in advance preferably in a database at least the locations of the available battery swap stations and/or recharge posts and/or fast rechargers, and/or for example the GPS unit or the cars' computer can be automatically updated about this for example when entering or nearing the relevant general area and/or for example through periodical global updates for example for the entire country for example through the automatic cellular or other wireless communication with the service provider's main computers. Another possible variation is that preferably the car's computer for example at least or in addition can also automatically sound a special warning for example when the energy level of the batteries is below a certain minimum level for example based on various statistics of the typical minimum and/or maximum distances to the next battery swap stations or for example based on a default minimum value, and/or for example preferably the user can also set for example as general defaults for example one or more energy level warning points in which the car computer will preferably automatically issue a reminder to the user for example 24/12/08 Yaron Mayer & Haim Gadassi 119/304 that the energy level is low. Another possible variation is that similar features can be used also for example in normal for example gasoline powered cars, for example by adding a similar interface between the car's computer and the GPS guidance system, and/or preferably the GPS or similar guidance system and/or for example the cars' computer preferably for example contain in advance also the locations of the available gas stations and/or for example the GPS unit or the car's computer are updated about this for example automatically for example when entering or nearing the relevant general area or for example through periodical global updates for example for the entire country for example through automatic cellular communication with some service provider like for example is preferably done with the electric car's service provider. Another possible variation is that preferably the car computer can also indicate to the driver preferably automatically for example how much energy the car battery is currently consuming for example at the exact moment or for example on average over a certain time window (such as for example the last 5 or 10 minutes or other reasonable period) and/or for example indicate automatically when the battery is actually getting back energy for example due to regeinerative breaking or automatic regenerative recharge for example during slowing down or going downhill as explained elsewhere in this application (for example by showing it through a virtual or real dial or bar which for example is in the middle when the battery is at rest and for example goes to one direction, for example to a red edge, as more energy is consumed and for example goes to the other direction, for example to a green edge as more energy is being regenerated), and/or for example the car computer can automatically display to the user the current energy efficiency for example in terms of the equivalent MPG (miles per gallon) or for example Kilometers per liter or for example directly for example in electric energy terms such as for example watts or kilowatts per mile, preferably also based on for example on the exact moment or more preferably for example over a certain period such as for example the last 5 minutes or more, such as for example minutes or 30 niinutes or one hour or other reasonable period (preferably by calculating automatically the average energy consumption on that period and converting it through the relevant conversion formula to the equivalent oil consumption, and/or can preferably also for example display this to the user for example in terms of cents per miles or for example per kilometer (or for example other coins or currencies which preferably the user can define for example directly preferably in advance and/or for example the defaults are preferably automatically selected by the computer for example according to the country in which the car is but preferably the user can also change them for example to. other coins such as for example cents or dollars even for example in countries other than the US), preferably based on automatic regular updates for example from the service provider's main computers about the current price per energy or for example on the last price which the user paid, and can preferably display this information to the user for example as the price of energy alone and/or for example also as the price including the payment for the battery, and/or the user can for example view this data for example also over larger periods (such as for example day or days or week or month or more) for example through the service provider's web site, which preferably keeps such logs automatically, and/or view also for example on the web site also similar data and/or statistics for example for other cars for example in general or for example according to type or brand (preferably based on average 24/12/08 Yaron Mayer & Haim Gadassi 120/304 automatic logs of other users ), as explained also elsewhere in this application.
Another possible variation is that for example the car computer can also calculate (for example based on regular updates about gasoline and electricity prices for example from the service provider's main computers) for example also the approximate saving for example on the energy cost (preferably including the payment for the battery) for example on a certain trip or for example over a certain period or for example over a certain distance, so that for example the car computer can tell the user for example at the end of a trip for example how much money he/she saved on that trip compared to what it would have cost him/her if he/she had to pay for gasoline on the trip or period or distance- for example from the time the user left the last parking spot for example until the user requests this infonnation or for example until the next time the user enters into parking (so that for example the user can request this info actively for example for a specific period or distance which the user an preferably defme or for example the computer reports this automatically at least in some situations for example unless the user disables such automatic reports), and/or similarly preferably for example the service provider's main computers include this information for example in the monthly statement sent to the users - for example how much they saved on energy costs for example during the last month (or other period) for example compared to driving the same distance with a similar gasoline car.

Since typically a normal town will have at least a few battery swap stations and for example on highways between towns there will be a battery swap station for example every 40 Kilometers or for example every 25 or 30 Kilometers or for example other reasonable number, if someone for example lives in Jerusalem and for example works in Tel Aviv each day and for example typically comes back from work with for example only with energy left for example only for an additional Kilometers in the battery (since typically he/she does not need recharge during daytime or for example his/her battery is automatically only recharged partially during the day - for example adding 20% of charge or other reasonable amount or for example adding a certain amount of Kilometers for example as an additional safety margin) as long as his/her daily commute does not near the range of the full charge of the battery which is for example 160 Kilometers), and normally his/her battery will then be recharged fully during the night and the user would typically on a normal day have no need for example to enter a battery swap station on the way home, and if for example the user later that evening for example after coming back from work decides unexpectedly to go for example to a movie or a mall which stretches the remaining energy (if it is planned in advance the user will typically enter a swap station already on the way home or for example request higher recharge priority for that day in advance), he/she can easily enter a battery swap stations in his town before driving to the new destination for example in the evening. The main problem is for example in smaller urban or rural settlements (such as for. example Moshav Bekoa in Israel) if for example the user similarly works for example at a place at a distance of for example 60 Kilometers or similar distance from home but there is typically no swap station within the settlement and the user might for example need or decide unexpectedly for example to travel that evening to visit his family in Jerusalem, and for example the nearest swap station or for example the nearest swap station which is in the right direction is for example 24/12/08 Yaron Mayer & Haim Gadassi 121/304 only 30 Kilometers sway from the settlement and the user's battery for example has only enough charge for 20 Kilometers. According to the variations described already elsewhere in this application, in order to solve this preferably the user can for example charge his/her car for example in one of the fast rechargers in his/her areas (since as explained elsewhere in this application preferably there is a normal speared of a certain percent of fast rechargers between normal recharge posts, so that for example on average for example at least 5% or 10% of the recharge posts are fast rechargers or for example other reasonable number), so normally such a fast recharger will be at a distance of for example up to 20 recharge posts away from the user's home, and if for example it takes 30 minutes to reach full recharge on a fast recharger, then for example the user can leave the car for example the entire minutes for example if he/she wants to eat first and/or prepare or finish a few things anyway before leaving (and preferably the fast recharger is automatically designed for immediate recharge as soon as the user connects to it and/or the user can for example request it) and/or for example if the user is in a hurry he/she can for example spend only for example 5-10 minutes at the fast recharger for example till his energy is boosted enough to reach for example the nearest battery swap station which is preferably also in the correct direction and/or for example some other destination, and/or preferably the car computer can automatically recommend to the user for example the desired minimum amount or time of recharge in order to be able to reach that swap station or for example other destination, preferably including a reasonable safety margin and/or can for example automatically indicate to the user when the charge has become sufficient, and/or for example users in such settlements (in which for example there is no internal and/or sufficiently nearby battery swap stations) and which typically travel back and forth each day for example a distance which would normally leave them with too little energy to reach the nearest swap stations without further recharge for example at evening if such unexpected needs arise as in the above example, preferably automatically receive higher recharge priority anyway, since they are the ones who need it much more than people who for example live in a large town (which typically has a quite sufficient number of battery swap stations) and/or who typically travel a smaller distance each day, so preferably for example the priority considerations preferably strive as much as possible to make sure that for example cars of users in such settlements in which for example there is no internal and/or sufficiently nearby battery swap stations are preferably automatically recharged for example during the work day to a sufficient extent so that when they return home they preferably still have enough energy to reach at least the nearest swap stations plus a preferably sufficient safety margin (preferably by taking into account for example the information about where the user lives - i.e. for example where he/she typically recharges at night, the typical distance he/she travels each day, the database of information about the relevant available swap stations and/or recharge posts and/or fast rechargers at or near his/her area, etc., as explained also elsewhere in this application), and/or for example once it happens that the user for example suddenly needs such a trip for example in the evening and for example does not have sufficient charge to reach the nearest swap stations for example without recharging first, preferably his/her priorities are automatically further increased (since this is part of the.drive patterns, as explained elsewhere in this application) and/or for example the car's computer and/or the service provider's main computers for example automatically ask the user 24/12/08 Yamn Mayer & Haim Gadassi 122/304 for example if and/or when he/she expects this to happen again, and/or for example preferably as a general rule the car's computer and/or the service provider's main computers preferably ask the user automatically for example at least once each day or for example at least under certain situations, for example when first going into the car in the morning or for example when entering a parking spot that has a recharge post or when connecting to the recharge post and/or for example a sufficient time before approaching or reaching for example the last battery swap station for example on the way home from work - for example if the user (or for example anybody else in the family) has any plans to go out again with the car on that day or for example if the user intends to drive or use the car (for example himself or for example by some other family member) for example today for example more than the usual mileage or for example more then N miles or Kilometers or for example more than N miles or Kilometers above the usual (i.e. for example above the user's car's average or usual daily commute)(preferably the car computer and/or the service provider's main computers compute N automatically for example based on the current state of charge of the car's battery or batteries and the typical energy use of the user for example on average or on the average of the relevant week day, so that N is the remaining spare mileage which should normally be available on that day, preferably including a certain minimal safety margin), and for example if the user answer yes (for example through voice command or for example by key control for example on the wheel, as explained elsewhere in this application) then preferably the computer asks the user also for example approximately how many additional miles or kilometers (for example in total or for example the part beyond N, for example in terms of distance or for example in terms of estimated travel time) he/she thinks he/she will need and/or for example asks the user to indicate the destination of the out-of-ordinary trip (for example through the computer interface or through a GPS guidance system) or for example the car computer asks this in one step (i.e. for example how many miles or kilometers beyond the user's normal daily usage or normal usage on that week day the user intends to drive today, for example with 0 for example indicating none), and/or for example the computer can ask the user for example when entering the car in the morning or for example when reaching the parking place for example at work for example approximately how many Kilometers (or for example miles or other measure) the user thinks he and/or for example other family members will need to drive in the car today, and/or similar variations, and preferably based on this answer for example the service provider's main computers can for example automatically increase the user's priority for example for daytime recharge at least for that day and/or for example based on this answer for example the car computer or the service provider's main computers (through the car's computer terminal) preferably if need automatically remind the user or recommend to him/her for example when leaving the parking lot to go through a battery swap station, preferably while also automatically recommending for example the optimal swap station that will least divert the driver off the way, as explained also elsewhere in this application. In addition, if the car computer (or for example the service provider's main computers for example through the car computer) for example asks the user for example when parking the car in a parking spot (i.e. for example when the user puts the gear or drive control in parking mode -for example as soon as the user has finished moving the gear or drive controller into the parking position and/or for example a certain amount of seconds afterwards, 24/12/08 Yaron Mayer & Haim Gadassi 123/304 which preferably the user can also adjust for example as one of the defaults, or for example after the user also turns off the engine and/or turns off the car key and/or for example removes the key, i.e. for example as soon as the user does these activities or for example within a short time interval afterwards such as for example a few seconds or more (or for example a minute or a few minutes or other reasonable interval) which preferably the user can also adjust for example as one of the defaults, as explained also elsewhere in this application) for example how long he/she intends to stay in that parking place or when he/she intends to use the car again or leave the parking spot (and preferably the car computer communicates the reply automatically for example to the recharge post and/or to the service provider's main computers, as explained elsewhere in this application), preferably the car computer (and/or for example the service provider's main computers through the car computer) preferably asks this for example only if the user pays for the parking through the service provider or if it is a parking spot with a recharge post (as can be determined for example by special optical and/or electromagnetic markings on such parking spots and/or for example on the recharge post which the car computer can preferably identify automatically for example through small video cameras for example below the car and/or for example on the front and/or sides (for example the same video cameras that can preferably be used also for other purposes, such as for example automatic retroactive recording of accidents for example through a constant buffer as explained elsewhere in this application or for example warning the user about wandering off the lane or for example being to close to the margin of the road or for example to a safety fence) and/or for example automatic Bluetooth or UWB or other wireless communication or for example infrared communication with the recharge post that is coupled to that parking place (since preferably the car contains an internal cellar communication unit, preferably coupled to the car computer, and since almost all cellular phones today come with a bluetooth chip and will soon come with UWB, the cost for using this variation should be negligible, and preferably the UWB or Bluetooth works for example for a distance of up to only meters or less, but more preferably for example only 5 meters or other reasonable distance in order to reduce the chance that the car computer might be confused for example between 2 nearby recharge posts, and preferably in this communication the recharge post also tells the car for example its serial number and/or for example its position such as for example as defined by GPS coordinates or other coordinates and/or for example by street name and house number and preferably informs the car computer for example if each of its socket is available or connected to a car now, and preferably this way and/or for example also based on its own GPS the car computer can for example remember automatically the various locations for example for logging the relevant user patterns, such as for example that for example near the grocery store the user typically stays only a few minutes), and/or for example if the user for example goes into a mall or movie for example in the evening and has enough energy to go home anyway, preferably the computer avoids asking him/her for exaniple about departure time since anyway almost certainly the car will also not be used for V2G services at such time anyway, since otherwise the question could be annoying or irrelevant. Another possible variation is that there are for example at least two parking states in which the user can for example put the gear or drive control - for example normal parking and temporary parking (which is preferably for example between the position of the normal parking and the other 24/12/08 Yamn Mayer & Haim Gadassi 124/304 possible positions of the control), so that for example the temporary parking position preferably locks the car gear and/or brakes exactly the same as the normal parking position and/or preferably does preferably all the same things as the normal parking position but preferably indicates to the computer for example that the user intends this to be a short stop of for example u-p to 5 or 10 or 15 minutes or less or for example other reasonable period (which preferably the user can also change for example through the car computer interface for example within a certain choosable range), so that for example when the user puts the gear or drive control in temporary parking the car computer preferably for example automatically avoids asking the user for example how long he/she intends to stay on that parking place or when he/she thinks he/she will come back and/or preferably avoids reminding him/her for example about plugging the recharge cable even if there is for example a recharge post coupled to that parking spot. Preferably such automatic questions and/or reminders are preferably enabled by default, but preferably users can for example disable these features or for example one or more specific questions or reminders for example if they consider the question or reminder for example annoying and/or for example can define for example more specific rules br for example conditions such as for example when to ask specific questions or use specific reminders or for example rues that affect all or multiple reminders and/or questions, for example that the computer should ask a question or make a certain automatic reminder only when they go to work or park the car at work in the morning or for example when they come back at night at or park the car at home but not for example when they travel anywhere else during the day or for example in specific types of places, and/or for example the user can for example disable or enable only specific kinds of questions or for example specific types of reminders (and/or for example the user can choose if he/she prefers to be asked about the expected departure time for example in terms of how long he intends to leave the car the parking place or for example in terms of entering the expected time of return), for example through entering a summary table of allowed questions and/or other rules, and this disabling or enabling or setting rules can preferably be done for example on the car's computer monitor, or for example through the user's cell phone and/or for example through accessing the service provider's web site (since preferably either way the changes or rules are preferably communicated automatically from the car computer to the service provider's main computers and/or vice versa as needed). In addition, preferably in order to speed this questioning process up and avoid annoying the user, preferably the car computer first preferably automatically displays the preferably automatically estimated departure time (or for example estimated length of staying in the parking place), preferably based as explained already elsewhere in this application for example on the user's typical drive patterns and/or week days and/or his/her typical past behavior for example in general or for example in the same place (for example work, or for example a specific mall, and/or for example typically when the user goes to malls in general for example based on his/her past behavior) and preferably asks the user to confirm for example by saying yes or for example to correct or adjust the time, for example by moving the dials on a real or virtual watch or saying the correct time or keying in the numbers. (As explained also elsewhere in this application another possible variation is that for example the recharge post for example asks the user about the time directly so that the user for example has to key-in the reply for example with a keyboard and monitor on the recharge post, 24/12/08 Yaron Mayer & Haim Gadassi 125/304 which is less preferable, or for example after the car computer senses that the cable has been plugged in it can for example ask the user about the time for example through wireless communication with his/her remote control, and then for example the user keys the reply for example on his/her remote control, but the above variations of preferably the car computer asking the user while he/she is in the car are more preferable and more convenient). The expected departure time (based on the normal user's patterns and/or a different time indicated by the user) is preferably used as explained also elsewhere in this application for example by the service provider's main computers for example for parking payment management and/or for taking this into account in the recharge priorities and/or for the V2G
services, so that for example when applying the V2G preferably the main computers of the service provider or of the electric company preferably try to use mainly cars in which the expected departure time is later or latest and/or for example cars in which the normal energy needs are such that even if the car's battery happens to be depleted by the maximum allowed V2G amount or percent at the time the user leaves (for example 20% or other reasonable limit), it will still for example normally or typically allow him/her to continue driving that day without the need for further recharge and preferably with a sufficient safety margin), and/or for example the computer preferably avoids asking the user about the departure time for example if the user's typical daily energy needs are such that normally he/she does not need any daytime recharge and for example typically has sufficient or more or sufficiently more spare energy for his typical daily needs so that even if the car's battery happens to be depleted by the maximum allowed V2G amount or percent at the time the user leaves it will for example typically or normally still allow him/her to continue driving that day without the need for further recharge and preferably with a sufficient safety margin (for example unless that user has a special trip planned for that day, which preferably the user indicates if needed), since in this case (and/or if the user also does not pay for the parking through the service provider or this is not needed for managing the parking payment, since as explained elsewhere in this application preferably the service provider can extend the parking time automatically and does not need to know the expected departure time for this) there is no need to ask this question (for example a user who travels on average only a maximum of 60 or 80 Kilometers daily or for example rarely travels beyond that, so the remaining for example 80 or 100 kilometers does not require normally any daytime recharge and has enough safety range for example for even maximum depletion due to V2G, and preferably in such cars the maximum amount or percent of depletion due to V2G can preferably also be increase automatically or for example by asking the user for permission in general, preferably together with extra payments and/or reductions and/or credits and/or other bonuses, such as for example also free parking or reduction in parking). Preferably in this case, preferably the computer will ask about the departure time only if the user indicates his/her intention of traveling beyond the normal distance on that day, as explained above. In addition, if the user for example was in a hurry and did not reply to the computer before leaving the car or for example forgot to reply or for example changes his/her plans later, preferably the user can preferably instantly update the expected departare time for example through his/her cell phone, for example by direct communication with the service provider's main computers or with the car's computer and/or for example through the service provider's web site, so that the 24/12/08 Yaron Mayer & Haim Gadassi 126/304 user preferably can see the current estimated or entered or modified departure time and can for example move it backwards or forwards and/or for example enter directly another time, and/or for example the car computer or the service provider can for example send the user an automatic reminder for example through SMS or email or Instant message or for example through an automatic message for example when the user enters the service provider's web site to indicate for example if the user intends to go out earlier or needs to travel a longer distance than usual (preferably this is done only if the computer determines that the question is relevant, as explained above) and/or for example only if the user's car is actually needed for V2G at that time and the service provider is for example not sure if it should be used (for example if the car would not have enough charge for example to reach home or for example if the user need the car unexpectedly in the middle of the V2G) or for example if the user's typical patterns have large statistical variations, and/or preferably the service provider or electric company's main computer preferably automatically also prefer to actually use for the V2G for example users who have lower statistical deviations than for example other users, i.e. for example users who for example rarely leave work for example at a significantly earlier hour than usual, and/or for example V2G services are mainly used when the user's car is in a place with more predictable or low deviation departure times, so that for example if a certain user for example typically rarely leaves work before time but for example when going to am mall or to a movie or for example to the center of town his/her length of stay has much more deviation, preferably the service provider or the electric company preferably automatically disable for example V2G services for example for such user when they are parked and connected to recharge post in such places, and anyway such user might not even desire to park near a recharge post for this reason if they don't need the recharge at that time and if they most likely will not be used there for V2G anyway, and especially for example if going to the mall or movies for example in the evening, when the need for V2G is much lower. In addition, preferably if the user for example goes out in the evening for example to a mall or to a movie and has sufficient energy to return home without any recharge (preferably with sufficient safety margin) preferably the computer can automatically recommend to the user for example not to connect to a recharge post since he/she does not need it and also there is little or no chance that he/she will be used for V2G
at such a time (preferably at least or especially for example if there is a shortage of recharging posts at the mall or they are crowded), and/or for example the computer only reminds or recommends to users to connect to a recharge post in such places only if they really need it for energy. Preferably when paying for the V2G
services preferably the electric company pays the service provider and/or users both for the general availability for example of the car batteries of the users who agree to participate and preferably also for actual usage, and preferably users can also request preferably explicitly for example to increase or reduce the frequency or amount of their participation for example in the V2G services for example in terms of priority for being used and/or for example in terms of allowed depth of recharge (for example if these users drive a short daily distance which give them sufficient spare mileage even if used to the maximum extent without recharge by the end of the day, and/or for example if these users typically return late anyway almost everyday, and/or for example if these users simply want an especially boosted revenue or credit or monthly subscription fees reduction and for example don't mind 24/12/08 Yaron Mayer & Haim Gadassi 127/304 even going to the swap station for example at least if they have to leave earlier unexpectedly and for example forget to inform the service provider or the electric company a sufficient time before that) (preferably usually this will happen only or mainly for example if the user has to leave unexpectedly early or if the user for example typically leaves early, such as for example at 2 or 3PM, since for example in case of users who typically leave for example at 6 PM there should be sufficient time after the peek time to return sufficient energy to their battery so that they don't have to go to the swap stations - at least for users who need that and otherwise would have to go to the swap station for example on the way home). So for example some users for example even if they return from work typically for example at might for example agree for extended V2G services for example even if in means every day or every few days having to go to the battery swap station for example on the way home if it pays well enough. However for example the electric company might not need many people like this if for example there are sufficient cars which can be used for V2G automatically with high reliability almost without any need for going more to swap stations, and/or similarly as explained elsewhere in this application preferably other users can preferably also for example request to block for example completely or partially the V2G services, so that they preferably give up all or most of the extra credit or reduction or revenue for the V2G
services, for example for the knowledge that they will need the swap station even less. In addition, preferably like in the case of trying to cheat the system by requesting unjustified high priorities, preferably the service provider for example uses for example suctions such as for example fines and/or extra charge (i.e. for example paying higher rates preferably together with a fine) and/or for example ignoring at least some of these requests - for example if the user for example systematically enters departure times which are for example substantially sooner than the real actual departure time and/or for example systematically indicates for example again and again for example that he/she needs to go on a long trip today and then does not really make such a trip (preferably by automatically logging this data), since if for example many people start doing this and/or make bogus requests for higher priority without sanctions against this it could seriously defeat the efficiency and/or proper functioning of the automatic priority system. Since most people live in large towns and/or travel a smaller distance per day, such as for example less than 40 Miles round trip per day, the effects of these priorities on the amount of daytime charging is not too big for the service provider. Another possible variation is that, as explained above, preferably for example in such a configuration for example the car computer will automatically remind the user for example each time to go for example to the near swap station on the way for example back from work to his home settlement for example in the evening or afternoon - for example if otherwise he/she will not have sufficient energy to reach the next nearest swap station after entering his/her home settlement or and/for example insufficient energy for example to return back to this same swap station for example from his/her home settlement, however this might still be insufficient since for example on normal days the user might typically ignore this warning since he/she normally does not need to travel such distance again at the same day and can rely of the night's typical full recharge, and/or for example the computer can be more specific and remind the user for example in such cases that he/she should enter the swap station for example if he/she thinks that he/she might want or need to go out again for example this 24/12/08 Yaron Mayer & Haim Gadassi 128/304 evening, and/or for example the computer reminds the user more or especially for example on week days in which based on previous patterns there is a bigger chance that the user will later want to go out again, such as for example near the end of the week, when the user for example more often goes shopping or for example to a movie. In addition, as explained also elsewhere in this application, preferably for these automatic reminders or recommendations the car computer preferably automatically takes into account also for example temporary congestions for example on the roads and/or in specific swap stations (of which it is preferably automatically updated by the service provider's main computers - for example globally or for example the updates are automatically more detailed about the current area and/or the near areas or near areas in the car's current direction) if relevant (i.e. for example if the different in congestion is worth choosing another swap station) and preferably chooses or tries to choose a near swap station which is on the same direction or route as the user is traveling and preferably also avoids or tries to avoid unnecessary driving around, so that for example the computer might choose a swap station which is for example a bit earlier on the road for example on the way home but is preferably on the same road or highway and/or at least does not require sidestepping or lengthening the route or for example no lengthening of for example more than a few minutes or other reasonable threshold (for example compared to choosing the next swap station which might be for example nearer to the user's settlement but requires for example non-negligible extra-driving for example sideways and back in order to reach it) and/or for example by taking into account for example the difference in any extra time or mileage needed to reach for example each of the relevant chooseable swap stations and for example the resulting difference in charge when the user reaches home, for example due to going to an earlier swap station which is on the same road instead of to a swap station that is closer to the user's home settlement but requires wasteful extra driving, but since after reaching home the user will rarely need to go on full range trips again that day, so for example if the user reaches home with a battery that is for example 80 or 90 % full this should usually make no difference. However in such automatic recommendation for example on the way home and/or for example when traveling to other places the computer preferably takes into account also if the user has for example indicated specifically that he/she intends for example a long trip for example to a specified location for example later that day, and/or preferably for example at least in case of having to choose between closely valued alternatives (for example when choosing between swap stations) preferably the car computer (and/or for example the service provider's main computers) can for example present to the user for example two or more choices for example together with their attractiveness scores and/or the relevant considerations and/or tradeoffs and let the user to choose, and preferably the computer (and/or for example the service provider's main computers) also learns automatically from the driver's previous choices and/or preferences (preferably also for example choices that the user has made for example by himself/herself for example not in the context of choices or recommendations offered by the computer), so that for example if the user shows clear preference for example to one of the solutions or choices for example after a one or few times or for example the user has already chosen in the past for example one or more times for example a specific swap station for example in general or for example under similar circumstances (such as for example driving in the same direction), 24/12/08 Yaron Mayer & Haim Gadassi 129/304 preferably the car computer (and/or for example the service provider's main computers) for example can preferably automatically remind the driver for example to enter a swap station for example based also on the driver's previous choices and/or preferences. Preferably the same or similar solutions are used for example also if the user lives for example in a large town but lives for example in the suburbs and is for example located beyond a certain distance to the nearest swap station or stations. Another possible solution is that since the car preferably typically has in addition to the main power battery or batteries preferably at least one or more smaller and lighter emergency batteries which can preferably be also hand carried and/or for example can be easily swapped by mobile battery swap units, and for example swapped for example in various post office stations or shops or other places authorized by the service provider (and/or for example the main power batteries or batteries are composed of a number of units which can also be swapped separately), as explained elsewhere in this application, so that there are for example 2-3 emergency batteries, each weighing for example 5-10 Kilograms and for example each capable of for example an additional 5-10 kilometers drive when fully charged, the emergency batteries might be for example sufficient for the extra energy needed to reach the nearest swap station, and/or for example if they have also been partially used for example during the day or for example are still insufficient or marginally sufficient, the user can for example swap at least one of these emergency or reserve small batteries (of course as batteries get improved capacity per weight this will be even more efficient, since for example new Lithium Ion batteries with nano-porous or nano-wire Silicon structures for example instead of the graphite cathode can typically have for example 8 or 10 times increased capacity compared to normal Lithium Ion batteries and are also typically fast batteries, so that for example the same size and weight main power car battery can go for a much further distance on a full recharge and/or for example the main power battery can be for example half size and weight and still go for example 500 or more Kilometers on a full charge, and/or for example the reserve or emergency battery can be even smaller and lighter, such as for example 5-7 Kilograms or less and still be sufficient for example for a 50 or more kilometers ride). This means that preferably for example at least in such small settlements which do not have their own swap stations or do not have sufficiently near other swap stations preferably there is at least one authorized place for swapping the small batteries which is preferably open 24 hours a day or for example at least until late at night and is preferably located for example at or near the center of the settlement or for example at or near its entrance or main entrance. Preferably at least some of the authorized swap places which enable swapping for example the small emergency batteries for example have matching rechargers which can for example recharge such reserve batteries for example over night for example individually or for example can recharge a few or more batteries together serially for example like with the normal power batteries in swap stations, and/or for example at least some of them rely on service trucks or cars of the service provider which for example pick up the depleted small batteries for example in the evening and for example recharge them over night for example at the nearest normal swap station and for example return preferably fully recharged small batteries for example in the morning. This can even be done preferably for example by the same service trucks which service stranded vehicles during the day, since typically for example they get much less calls for example late 24/12/08 Yaron Mayer & Haim Gadassi 130/304 in the evening or for example early in the morning since there are much more people on the roads during daytime. Another possible variation is that preferably for example the government preferably forces the service provider (and/or for example at least or especially if he/she has officially and/or on in practice a monopoly for example in the country or in the area, and/or for example the service provider does this voluntarily for example in order to improve the service) to provide sufficient swap stations for example at least in or near settlements or settlement areas in which there is for example at least a certain amount of people, so that preferably for example the average or for example maximum distance for these people to reach for example the nearest swap stations is preferably for example smaller or substantially smaller than for example the normal distance between swap stations for example on the highway, so that for example even if the service provider for example normally provides for example swap stations on highways for example typically at distance of for example 40 Kilometers from each other, preferably the service provider is for example required to put for example at least one such station for example at a distance of no more than for example 10 or 15 kilometers (or other reasonable distance, for example based on various statistics) for example from such settlements or group of settlements and/or for example.is at least required to put for example a larger or considerably larger percentage of fast rechargers for example in such small settlements (or for example in even smaller settlements that still do not get the swap station close enough) for example in comparison to the percent of fast rechargers in a large city that has for example a sufficient number of swap stations for example even within the city and/or for example is required to increase the relevant recharge priorities for people in such areas for example as explained above for example at least until sufficient battery swap stations are installed in these areas, and/or for example is required to put for example in such small settlements for example at least a temporary swap station with at least one mobile battery swap unit, such as for example the units that can preferably be used by service trucks to swap batteries in stranded vehicles on the road, and/or for example preferably the service provider can use for example a computerized map of the covered areas which preferably shows for example at least the main highways and preferably at least the settlements and cities of the relevant minimum size and above and preferably a visual indication of their size and preferably by feeding in the relevant rules and/or parameters preferably for example the service provider's main computers can preferably automatically suggest for example an optimal arrangement of swap stations so as to preferably comply with preferably all the relevant requirements while preferably using an efficient spread of swap stations preferably without unnecessary waste -for example by automatically generating the suggested locations of the swap stations and/or their recommended sizes for example on the map. (This is preferably required also since for example otherwise it would be unfair for example to reduce taxes on electric cars and for example increase taxes on gasoline cars at the same time for example while not offering a fair solution to people who live in the periphery). Another possible variation is that for example until the proper infrastructure is installed various areas for example in small settlements and/or in the preferably, people who live there are for example exempt from increased taxes on gasoline cars, but that is less preferable, since it would delay the entrance of electric cars). And since, as explained elsewhere in this application, preferably the service provider can easily swap for example by using a modular underground 24/12/08 Yaron Mayer & Haim Gadassi 131/304 interface for example between fast rechargers and normal typically passive recharge posts and/or for example by using mobile rechargers which can for example be even more easily moved, the service provider can for example use more fast rechargers for example in such small settlements for example until adding sufficient battery swap stations in the are, and can then for example later move for example some of the fast rechargers to other places for example after the swap station has been added and the fast recharger are less needed there or for example are more needed in other places. Another possible variation is that at least if for example the mobile battery swap units used by service trucks can for example also swap the main power batteries of cars for example on the side of the road when needed, as explained elsewhere in this application, preferably such mobile battery swap units can also be used for example in the same places in the small settlement where for example the small emergency or reserve batteries can be swapped or for example the same mobile swap units can be used to swap both types of batteries, so that for example at least in some such small settlements preferably at least one authorized small battery swap place preferably includes at least one such mobile battery swap unit and so can also swap main power batteries, and/or there are small or temporary battery swap stations that use one or more such mobile battery swap units for swapping the main power batteries of cars, and then these batteries are for example recharged locally preferably at night or for example are automatically carried away for example in the evening and returned for example in the morning for example by the same service tuck that picks up the small reserve/emergency batteries for recharging for example at the nearest normal battery swap station (However this is less preferable since for example such a service truck might typically be able to carry for example only up to ten or twenty for example 150 Kilogram Power batteries), and/or for example in such small settlements or group of small settlements the service provider preferably installs for example at least one smaller swap station which for example has the normal equipment as a normal large battery swap station for example in a large city or on the highway but for example has a considerably smaller number of actual swap spots and/or a smaller number of rechargers and thus can be for example considerably cheaper than a normal battery swap station. Another possible variation is that for example users are offered by the service provider for example extra credit and/or for example other benefits for example for agreeing to rely more on battery swap stations than on daytime recharge even if they for example automatically deserve higher priorities for example due to living in such small settlements and traveling a large distance daily as explained above, so that for example such users who agree for example to use the swap station for example on the way home (preferably while traveling on the highway on an inter-city road, thus typically being able to visit the swap station without wasting time on unnecessary additional driving to and from the battery swap station) for example each day for example instead of being recharged in daytime or for example when they think they might need the extra energy for example in the evening and/or for example agree to have lower recharge priorities during daytime can for example receive preferably considerable reductions for example in their normal monthly payments and/or for example other bonuses, and/or this is done preferably for example at least or especially for example in hot summer days when the peak demand in midday can be for example considerably larger than for example in times when the weather is more temperate (since otherwise it might be for example quite wasteful if for example all those 24/12/08 Yaron Mayer & Haim Gadassi 1321304 people for example from small settlements which travel a sufficiently large distance daily as in the above example for example receive also daytime recharge every day just in case they might need it unexpectedly even if for example they actually need the extra energy only on rare occasions, and this is also another reason why a certain percent of fast rechargers is a good idea, or for example at least or especially for example in residential areas, especially if they are used for example mainly in the evening for example when needed unexpectedly, since typically the recharge costs at the evening can already be considerably cheaper than during midday peak time).
Another possible variation is that for example on special events in remote places, such as for example some concerts or ceremonies or for example army events, preferably the service provider can for example provide in advance for example a certain number of service trucks for example with mobile battery swap units, so as to augment for example the normal number of battery swap stations in the area.

Of course various combinations of the above and/or other variations can also be used.

Another possible variation is that preferably the car has also an alann in the battery area for example in case someone tries to steal the battery. Another possible variation is that the car is for example designed in a way that the battery container can be opened only by entering a special code or codes (which for example can belong to the car and/or to the battery), so that for example without the code a thief would have to work very hard in order to be able to penetrate the battery area and/or similarly for example the battery or batteries can only be recharged after entering the code (so that for example the code is needed preferably for any type of recharging - such as for example at the service station, from a street recharger or recharge post, or from another car, and of course preferably also for enabling for example recharging another car's battery, so that for example for helping another driver by recharge his/her car preferably both the helping driver and the helped driver have to enter their respective codes). In addition, preferably the battery chamber in the car is designed so that the battery or batteries can be removed only with special mechanical equipment. Preferably if the code is lost it can be restored for example by accessing for example a central computer for example through a cellular phone, for example with appropriate identification of the owner.
Another possible variation is that preferably this code can also be used as further protection against theft of the electric car, so that for example if the owner reports the car as stolen, the recharge and/or battery replace code is preferably canceled for example at the central computer or database, so that the thief cannot recharge the car or remove the battery for example without having to take the car apart. Another possible variation is that preferably the battery itself and preferably also additional parts in the car preferably have a unique digital id which preferably cannot changed or at least cannot be easily changed, so that for example when the car comes to a service station preferably the service station's computer automatically communicates digitally also with the battery (which has to be done anyway for example if the automatic sorting of batteries for recharging is used, as explained above) and/or with additional parts in the car and can preferably check in one or more central databases and can preferably automatically issue an alert for example if the id indicates for example that the battery or for example one or more other car 24/12/08 Yaron Mayer & Haim Gadassi 133/304 parts is stolen (This means that preferably for example when the battery is replaced the service station's computer preferably reports automatically for example to one or more central databases the Id of the car together with the Id of the recharged battery or batteries that were supplied to the car, so that for example if the battery is later stolen from the car, the id will not fit the id of other car if the thief for example comes later to the service station with the stolen battery), and/or for example such a check can also be done automatically for example by street recharging posts, and/or for example if the car was reported and preferably verified as stolen then the recharger or recharge post for example directly or through a command from the service provider (and/or for example the service provider for example through the cellular network) can for example transmit a certain code which causes the car's computer to become locked so that the thief cannot move the car (preferably together with automatically sounding a loud and visible alarm) and/or for example the recharger or recharge post can automatically notify for example the service provider of the exact location of the car (or for example the user himself/herself can for example remotely transmit a certain code or sequence of codes for example directly through his/her cell phone that can cause the car remotely to become locked and stop functioning and preferably automatically sound a loud and visible alarm, and preferably the car computer automatically transmits its location repeatedly for example by GPS and/or for example by cellular network triangulation of nearby cells, preferably through the cellular network), or for example the service provider's computer can automatically locate the car through the preferably unique ID of the recharger or recharge post. Preferably for example if a stolen car is automatically locked off for example by remote signal for example through the cellular network preferably the user or for example the service provider has to send preferably one or more preferably long sequences of code so that for example hackers cannot remotely lock cars in an unauthorized way, and preferably the locking mechanism and the cellular communication unit are embedded by hardware into the car's computer and/or into other hardware of the car so that preferably it cannot be overridden or disabled without taking the car apart, and preferably the computer automatically notifies the thief for example that the car is locking itself off and that he/she for example has 30 seconds (or other reasonable time) till the car will stop moving, and/or preferably the car computer preferably automatically slows down gradually so that the thief for example has a chance to move the car to the side of the road before it stops, and/or for example the lock down is activated automatically for example the first time that the car goes below a certain speed or for example stops (for example in a red light), and preferably if the car was locked by mistake or for example after the owner finds it preferably the user can also for example phone the service provider and after proper identification for example with a password and/or other questions preferably for example the service provider can also for example remotely enable it for example with another code. (Of course these variations of automatic remote disabling of stolen cars can also be used for example with hybrid cars or with non electric powered cars). Preferably the rechargers or recharge posts are updated automatically for example by sending information through the electrical grid or for example through a cellular network or for example WiMax interface to the internet, as explained above, preferably with digital signature and encryption. Another possible variation is that for example other cars' computers are updated automatically for example with information about stolen cars 24/12/08 Yaron Mayer & Haim Gadassi 134/304 and/or batteries and/or other updates, for example when recharging or when entering service stations or for example by the direct cellular or other wireless communication for example with the main computers of the service provider, and preferably automatically further transfer this information on similarly, so that for example if a recharger or recharge post is temporarily disconnected from the main computers, or for example if for example in order to save costs for example at least some passive recharge posts do not contain cellular or other network communication, they are preferably updated automatically when a car that was previously in contact with a connected recharger or that was updated by direct cellular or other wireless communication for example with the service provider's main computers connects to it. So this way, preferably even disconnected recharge posts can preferably for example refuse to offer service for cars or batteries reported as stolen or for example to cars that no longer have a subscription. (However, as explained elsewhere in this application, recharge posts which contain the actual recharger are preferably always connected to the main computers for example by cellular communication) since otherwise they cannot receive directly the real time instructions). Another possible variation is that for example at least some recharge posts are preferably programmed automatically for example by instructions from the service provider or for example by entering special secret codes which enable programming them for example through the user interface, so that for example only a certain list of cars (as identified for example by their unique Ids) are allowed to connect to them, such as for example recharge posts that are for example in private parking places of buildings, so that for example only cars with a listed Id or for example only people who live in the building or for example who have or are given a special password or secret code by people in the building can for example recharge through them, and/or for example users who have special smart cards or other physical devices which are required by these recharge post, so that for example the special physical device is needed, or for example either the special device or the secret code is needed. Another possible variation is that for example electric cars are programmed to identify themselves automatically for example with an RFID or other type of automatic broadcast for example when entering a toll road, so that for example the toll road system can also identify and issue an alert automatically for example when a car reported as stolen enters them or for example if the car has been hacked with so that it does not identify itself, or for example an alert can be issued automatically if for example the thief copies a valid code of another car and then for example the same car is supposedly identified at the same time or at a too close time proximity in two sufficiently distant places, which is preferably done for example by one or more central computers finding such discrepancies, so that the alert can be issued preferably in real time, or for example at least later. Another possible variation is that preferably for example the car's computer can check for example through encrypted communication if a recharger is legitimate, so that preferably for example only a legitimate recharger can supply a valid response, and for example if the car's computer finds that the recharger is not legitimate it can for example warn the driver or for example block automatically recharging through it. Of course various combinations of the above and/or other variations can also be used.

24/12/08 Yamn Mayer & Haim Gadassi 135/304 Another problem is that typically for achieving different speeds in electric cars the car's system typically uses different frequencies and/or voltages with the electric engine (which is typically AC) and there is no changeable gear, but the engine does not have the same efficiency at different speeds. So preferably the engine is designed to have the best efficiency at a speed that is fast enough for most purposes while still good enough from considerations of air resistance (for example near 80 or 90 Km/H), and/or preferably the engine contains multiple coils and/or other multiple parts or elements (and/or for example there is more than one engine), which can be for example automatically switched for example by multiplexers for example mechanically and/or electronically, so that for example for each range of speeds or for different ranges of speed the system also switches to a more optimal or to the most optimal coil or element or engine for that range of speeds, and/or for example the electric car includes also at least a partial, preferably automatic, gear, which preferably works in combination with using the different frequencies and/or switching to different coils or elements, so that preferably for example the gear is only used in some cases or for example with automatic combinations with the frequency and/or with the coil or other element switching, so that for example the gear shifting is done as a combination of electrical and/or mechanical shifting and/or for example at different ranges of speed changes in speed are done by different combinations or by only part of them, so that preferably the engine's efficiency is improved to be close to optimal in many speeds or most speeds or for example any speed. I-lowever, having too many different types of coils near the engine's rotor can cause for example induction problems between them, and for example at higher speeds less coils are needed, so another possible variation is that preferably when switching preferably automatically between different coils or elements preferably the system can also preferably automatically move physically for example at least some of them closer or farther from the rotor or rotors (for example by pulling them up or down or moving them sideways) and/or for example rotate them. Another possible variation is that the user can for example define for example through the car's computer the preferred speeds and/or the system can for example identify them automatically according to automatic statistical analysis of the driver's or the car's behavior over time, so that for example if the driver drives mainly for example at speeds between 50 to 90 Km/Hour, preferably the car's computer can for example automatically move into position a certain set of coils so that for example less physical changes are done during the drive itself or for example switching between less states during the actual drive can be efficiently implemented.

Another problem with electric car batteries is that if the car is left for example in the sunlight for a long time during hot hours the car batteries might easily become too warm, which can significantly shorten the life of the battery.- So preferably the batteries (for example the batteries themselves or for example a frame that contains them or for example the car's battery container) are improved to contain for example a heat exchange sink or radiator so that this heat sink/radiator can be cooled for example externally and/or preferably the electrolyte in the battery can preferably also be circulated internally within the battery into the area of the heat sink and/or also with the help of air conditioning, so that preferably the electrolyte can be directly cooled more efficiently, and/or preferably the car's computer (or for example the recharger's computer or for example a microchip in the batteries) 24/12/08 Yaron Mayer & Haim Gadassi 136/304 preferably constantly or for example at reasonable intervals preferably monitors the state of the batteries (including for example temperature and/or additional parameters) and can preferably for example activate for example automatically for example once in a while for example air and/or liquid cooling of the batteries' heat sinks and/or for example can cool the batteries at least part of the time for example through a channel from the car's main air conditioner, and/or similarly preferably the batteries can be automatically also heated when needed (preferably only when the driver is in the car), for example if the temperatures become too cold, since for example in sub-0 temperatures the batteries' efficiency can go down for example even by 20%. Another possible variation is that for example when the user turns on the heater in the car for, for example through the air conditioner, example when driving in the winter preferably the car's system can automatically use for example the heat which is normally generated from the batteries as at least part of the source for the heating. In addition, preferably the car's computer is connected for example to various sensors for example in the batteries themselves and/or in the battery container which can for example alert the user automatically for example if one or more batteries (or for example super capacitors or other preferably fast recharge device) for example exceed a certain heat threshold and/or for example become unstable or start behaving erratically and/or for example change their voltage (for example to higher levels that indicate overcharging or for example to lower levels that indicate undercharging) and/or for example if one or more batteries start to leak chemically (for example based on humidity sensors and/or for example sensors of the electric resistance on the external side of the battery and/or similar sensors) and/or for example if one or more batteries start to become dry (for example by viscosity and/or acidity sensors inside the battery) and/or for example if one or more battery or super capacitor starts to discharge or leak energy by itself.
Preferably for example at least in case of an indication of a serious malfunction or danger in the batteries preferably for example the car computer preferably issues a more conspicuous warning and/or for example even at least temporarily disconnects for example at least the problematic battery and/or for example instructs the user for example if any urgent action is recommended. Another possible variation is that for example the batteries and/or for example the recharger and/or for example other sensors and/or elements in the car and/or for example the car's computer can preferably keep for example an automatic log for example about relevant problems encountered for example including for example the time and/or for example the unique Id of the car, and preferably this can be for example automatically reported to the main computers of the service provider for example when connecting to a recharge post or for example when the batteries are swapped and/or more preferably for example the car computer automatically updates the main computers of the service provider about such problems (for example through direct cellular or other wireless communication or for example when connecting the a recharge post), so that for example the car's computer and/or the main computers can discover in advance for example if there is some problem for example in the batteries or in the car or for example in the car's recharger or for example some other part which for example endangers the car or for example endangers the batteries, and preferably in such or for example at least in severe cases preferably for example the car's computer and/or for example the service provider's main computers can preferably for example automatically issue for example an immediate warning to the user 24/12/08 Yaron Mayer & Haim Gadassi 137/304 and/or for example can automatically slow down or for example gradually bring the car to a stop if needed (as explained also elsewhere in this application), and/or for example the service provider's main computers keep such logs in their database for example also so that for example if the batteries are later found to be damaged for example after swapping them to another car the service provider can for example use these logs for example in order to determine for example if such damage is the result of for example one or more faulty devices in one of the previous cars in which they were installed or for example some other occurrence in a previous car (preferably the data in such logs and for example the unique car Ids and/or for example the unique battery Ids is based also for example on hardware encryption keys, so that it is much harder for example to forge such data). Another possible variation is that preferably there are for example electric switches or other sensors for example at the top edges or at the covers of various containers which have to be normally closed, or for example in the container itself, for example under the hood of the car, so that for example if someone opens the radiator to check the amount of water and forgets to close the cover, preferably for example the car computer and/or for example some automatic visual indicator such as for example light (and/or for example auditory alert) can preferably immediately alert the user about it for example if the user tries to start driving while the cover is still open (this is very important since forgetting to close a cover can cause severe damage after some time for example if the fluid spills or evaporates), and/or for example there are temperature sensors also for other components in the car such as for example the engine or other critical components, so that for example the car's computer and/or for example a light indicator (and/or other visual indicator) and/or for example auditory indicator can warn the user also for example if the heat of the engine or for example some other component or critical component (such as for example the inverter) for example exceeds a certain temperature, and/or for example the car computer can for example can also start warning the user in stages, for example if the engine heat or other component heat starts to go substantially up below the normal behavior, for example even before it approaches any critical threshold.
Preferably these warnings can also be based on deviations from expected behaviors and/or on comparison for example with the outside temperature (for example by using also at least one temperature sensor on the outside of the car), so that for example the car computer can warn the user if the engine's heat and/or for example the battery's heat and/or for example the inverter's heat is for example too low or too high for example compared to the expected for example based on the outside temperature and/or for example based on the present current and voltage being consumed, and preferably such warnings are displayed or sounded for example if the deviation from the expected (preferably based on these parameters and/or taking into account also the outside temperature) are for example beyond a certain threshold. Another possible variation is that for example the car computer can automatically warn the user for example if the pressure in one or more of the wheels goes down below a certain threshold, for example by using a pressure sensor for example in the pressure valve which is nonnally used for filling the wheel (for example by replacing the normal valve with a special unit), such as for example by using a small capacitor or other sensor, and preferably each of these units has for example also an RFTD with a different identifier, and for example one central communication unit for example in the middle of the bottom of the car sends energy 24/12/08 Yamn Mayer & Haim Gadassi 138/304 to these RFIDs and communicates with them for example once every few minutes or for example once every hour or other reasonable time and can for example report to the car's computer for example if the pressure in one or more of the wheels goes down below a certain threshold, or for example the pressure valve or the wheel itself contains for example a coil which changes its shape according to the pressure (or some other electric element which changes its shape based on pressure in a way that alters an electromagnetic behavior) and for example a magnet and for example two other coils for example on the wing near each wheel (for example with the magnet on one side and the two small coils on the other side) can act as sensors for example when the coil passes near them and can transfer this information for example through a wire to the car's computer so that for example the computer itself decides if the data warrants any special attention (both of these solutions can be for example considerably cheaper than the existing solution of using four RFIDs which each communicates with its own special communicator), and/or for example by using a video camera which transmits the shape of the wheels to the car computer for automatic analysis. Another possible variation is that for example the car computer can preferably automatically remind the user for example when it is required or recommended to check or give treatment or replace certain elements in the car, for example based on the time since the car was manufactured and/or for example based on the mileage and/or for example based on the average temperatures and/or for example humidity in which the car was placed for example most of the time and/or other parameters (for example by automatically logging for example average external temperatures and/or other parameters over time with appropriate sensors), and/or other parameters, and/or for example based on automatic sensing of the condition of at least some of these parts, since for example many times if a certain part actually starts to malfunction it can damage additional elements, so this precautionary checking and/or treatment can actually save the user money.
Preferably for these reminders the car computer compares the relevant measurements or parameters against an internal database and/or for example the database can also be automatically updated also for example when connecting to the recharger or recharge post, for example if the manufacturer finds out that for example one or more elements needs special attention or for example need to be replaced at authorized service stations, so that for example users can be warned automatically through automatic messages for example when connecting to the recharger or recharge post, and/or for example automatic software or firmware updates can be done when connecting to the recharger or recharge post, explained also elsewhere in this application. Another possible variation is that there are for example various sensors for example in electric cars and/or for example in hybrid cars and/or for example in gasoline powered or diesel powered cars (and/or for example especially in trucks) which can detect for example leakage of oil (for example from a gear) or for example leakage of diesel, since for example spilled diesel for example from trucks can be very dangerous and can cause serious accidents due to cars sliding. Another possible variation is that for example a special color is added do diesel or other types of oil which might spill from cars, such as for example fluorescent colors which for example glow when exposed to light or air, so that for example if there is a diesel or oil spill preferably drivers can see it from sufficient distance and thus slow down in time and/or try to avoid going into it.
Another possible variation is that for example the electric car (or for example 24/12/08 Yamn Mayer & Haim Gadassi 139/304 normal or other type of car) preferably has for example one or more video cameras which for example automatically record what happens for example at least in front of the car and preferably also sideways and/or backwards, for example by automatically recording into a circular buffer of for example at least a few seconds or more preferably at least a few minutes or for example even a few hours or other convenient period, so that for example in case of an accident or near-accident the driver can for example press a button which causes for example the recordings of the last few minutes (or other time period which the driver can preferably chose) to be saved for example in a special file or files on the car's computer, so that the driver can use it for example to prove later what happened or can for example use it to find out for example the number of a car that previously for example causes damage to the car for example while parking, if it happened for example within the time frame of the circular buffer, and/or for example in case of damage to the car preferably the computer senses it automatically and can preferably automatically save the relevant video or videos of for example at least 30 second before the accident until for example a few minutes after it (or other reasonable time range before and/or after the moment of impact) for example automatically in one or more separate files even if the user is for example not around or for example forgets to press the save button. Another possible variation is that preferably for example the car's front and/or back bumpers preferably contains also for example a shock absorbing gel which is preferably sufficiently viscous and can convert for example at least some of the impact to heat and/or for example mechanical energy, preferably in a way that does not damage the bumpers when the impact speed is sufficiently low and preferably the bumpers this way preferably both protect better for example a person in case the car bumps in to him/her while preferably also preventing or reducing damage to the bumper itself for example while hitting a hard object or for example another car. Another possible variation is that for example the car's computer can automatically sense for example if the driver is beginning to fall asleep during driving or for example is fainting or for example has become otherwise incapacitated (for example based on automatic monitoring for example with a video camera for example of the orientation of the user's head and/or for example of the back and/or shoulders and/or for example based on automatically sensing for example the galvanic skin response for example through sensors on the driving wheel and/or for example based on remote sensing of for example brainwaves and/or for example heartbeat) and can for example automatically warn the user and/or try to wake him/her up, and for example if this still does not work then preferably for example the car's computer can automatically start slowing down and for example gradually moving into a stop for example on the margin of the road (while preferably taking into account for example the speed of the cars in front of it and/or behind it and preferably for example sensing automatically the lane markings).

Another possible variation is to use for example one or two or more preferably small wind turbines or other devices which can extract wind energy and/or especially for example energy from wind turbulence on the car itself (preferably multiple small turbines of for example 20 centimeters height) for example along the rims of the car's top and/or for example at the back of the car and/or preferably in the area or areas where most of the wind turbulence created by the car's motion is 24/12/08 Yaron Mayer & Haim Gadassi 140/304 concentrated, so that at least some of the air turbulences that are created anyway while traveling, specially when at high speeds of for example 80 Km/h or more, are preferably used also for example to help recharge the car's batteries along the way.
These turbines are preferably shaped in an aerodynamic way so that preferably only the blades that have to be moved by the wind create some resistance, since the intention is to take advantage of air turbulences that exist anyway when traveling at fast speed while trying to avoid as much as possible adding to the air friction -which creates a clear benefit as long as the energy input from these turbines is sufficiently larger than the added air resistance which is created by their presence (preferably for example at the back of the car this can be done most efficiently since much of the air turbulence is concentrated there and adding a turbine there especially if the external shape of its frame is for example like a cone-end shape can have a really minimal effect of adding air resistance). In addition, preferably this wind-energy or air-turbulence energy extraction unit preferably adjusts itself automatically or is for example automatically adjusted for example by the car computer for example according to the car's speed or for example the wind speed -so that for example it can protrude for example more or less for example at the back of the car and/or can for example change its shape and/or orientation and/or position for example in a way that optimizes or improves its energy extraction efficiency for example based on the car speed and/or wind speed or for example optimizes or reduces the additional drag which it creates itself for example in a way best fit for the current car speed or wind speed. Another possible variation is that there are for example at the back or the car for example air conduits which preferably concentrate the wind created by the car's motion preferably more optimally on the turbines or other wind energy extraction unit and/or help convert the turbulences into a more regular flow of air. Another possible variation is for example using for example at the back and/or top and/or sides and/or back of the car for example devices that can convert at least some of the noise energy created by the car's motion (preferably mainly the noise created by the air resistance) back to energy for additional recharging of the car's batteries along the way. Another possible variation is that since the electric car's engine can be considerably smaller than in a normal gasoline powered car, preferably the front part of the car is shaped or designed aerodynamically for example like the front part of a water drop or a similar shape -for example by making also the width of the car's front part round and substantially thinner then the width of the car at the area of the passenger seats. Another possible variation is that for example the aerodynamic shape of the car is also improved by adding for example a vertical front column with a arched shape (for example from glass or perspex or transparent plastic) for example in the front of the car at the front side of each of the front windows (so that for example a few centimeters in front of the front windows are protected from direct wind by this column) so that even if driving with open windows for example on the highway the air drag caused by open front windows is reduced. Another possible variation is that preferably the car uses for example preferably printed preferably transparent thin film solar cells which for example cover at least some of the windows of the car and/or for example at least some of its metal surfaces for example on the top and/or on the sides for additional automatic recharging of the battery preferably whenever possible. Another possible variation is that for example the aerodynamic shape of the car is further improved by giving the back of the car a shape like the sharp end of a cone or for example 24/12/08 Yaron Mayer & Haim Gadassi 141/304 similar aerodynamic shape, however in order not to consume for example too much parking space, preferably the cone-end shape at the back of the car is preferably made for example from a flexible or bendable or collpseable material or for example from plates on hinges (for example made of metal or plastic or for example flexible plastic or other materials) that are preferably controlled automatically by the car's computer, so that for example when the car parks preferably the cone-end or similar shape can be automatically collapsed or compressed to occupy less space and when the cars travels or for example exceeds a certain speed preferably the cone-end shape is automatically restored, and for example if the car enables for example automatic switch to neutral or similar state when going down hill, in which case preferably the car's speed is automatically controlled for example by automatically using the speed to recharge the battery and/or for example by automatically increasing the air friction as needed, as explained below, in this case for example preferably the shape and/or orientation for example of these same plates (or at least for example the top plate) can preferably be reversed for example into a vertical wall or concave shape.

Another possible variation is that for example the car's firmware is improved (for example in electric cars and/or in gasoline driven cars and/or in other types of cars) so that preferably for example the user can enable or disable a mode in which for example when the driver takes his/her foot off the gas lever (or drive or power lever for example in case of an electric car) and/or for example as soon as the driver touches the brakes lever (for example even before starting to press it), preferably the car's gear automatically shifts to neutral (or similar mode in an electric car even if it does not have a gear - which is preferably implemented for example by decoupling the electrical motor from the wheels or for example by allowing the electrical motor to rotate freely together with them) and/or even the engine is automatically turned off for example partially or in full and/or for example at least if the car is moving in at least a certain speed (for example 20 or 40 or 50 Km/H or other reasonable threshold) and/or for example at least if the car is moving in a downward slope (which can be measured automatically for example by the inertia behavior of the car and/or for example by an automatic horizontal inclination sensor, which preferably takes into account also the weight on the various seats, for example if there are passengers in the back seat) or for example if the steepness or the slope is above a certain threshold minimal angle and/or for example below a maximum angle, and/or for example until the car reaches a certain speed (so that for example if while in this mode the car starts exceeding a certain speed limit, such as for example 100 Km/H
or other desired threshold which preferably the user can change, preferably the gear and/or engine for example preferably automatically returns to normal operation for example until the speed again reaches below another threshold, such as for example 90 or 80 Km/H or other reasonable threshold), and preferably the gear and/or engine automatically returns to normal operation for example when the user presses again the fuel or power or drive lever with his/her foot and/or for example on the brakes and/or for example a special lever or button which is designed to preferably instantly return the car to normal drive mode when needed. This can save a lot of energy especially when going down in a slope. Another possible variation is that for example if the car starts moving too fast in this state for example because of it having a good aerodynamic shape and/or the slope being too steep, preferably the 24/12/08 Yaron Mayer & Haim Gadassi 142/304 driver (and/or for example the car's computer automatically) can preferably activate an automatic speed reducing element based for example on increasing the air friction, for example by opening a plate like or concave dish-like friction elements or other shapes or devices with similar function, for example on both sides or the rear end of the car's roof or at other convenient locations, so that preferably for example changing the angle and/or for example the amount of protrusion of these dishes or plate or other protrusions or devices can be used in order to control more finely the desired speed without having to corrode the brakes, and/or for example the gear and/or engine automatically temporarily returns to normal operation for example until the speed again reaches below another threshold, as explained above, and preferably the user can in this mode set for example the maximum desired speed and/or for example a preferable cruising speed so that the car can automatically use it as the maximum speed threshold and/or can also set for example the minimum speed thresholds (for example the initial speed threshold for entering neutral mode and/or for example the later minimum threshold for reactivating neutral after neutral has been temporarily deactivated due to reaching the maximum threshold) and/or additional parameters (however preferably the car can of course exceed the upper speed threshold for example if the user presses again the drive lever).
Another possible variation is that for example while driving down a slope and/or at least when driving in the automatic neutral or similar mode or engine-off mode as explained above, preferably the car's speed is also used automatically to recharge the batteries, thus preferably also adding to the slowing down and automatic speed control. Preferably this recharging is also dynamic so that for example the amount of downspeed energy used for recharging the batteries can preferably be automatically increased or reduced according to the current speed and the desired speed, and preferably in this neutral or similar mode preferably for example pressing slightly on the brakes for example below a certain limit preferably automatically activates other braking mechanisms before activating the actual brakes - for example by automatically increasing the air friction as explained above and/or the amount of energy drawn for recharging the car. So preferably the car's computer can sense for example through a potentiometer the level of pressing on the brakes and can for example automatically decide for example if to increase the braking power for example by increasing the air friction and/or for example increasing the amount of energy used for the recharging of the batteries as explained above (and/or for example using the energy directly for example for providing directly energy for example if the air conditioner or headlight are own and/or for example using it for heat dissipation) and/or for example using the engine like an alternator and drawing current from the engine in order to reduce the speed, and/or for example activating the normal brakes, and/or the car's computer can preferably for example in this state similarly automatically decide how to increase the car's speed for example when the user releases the brakes or for example starts pressing on the drive pedal (so that for example the computer first reduces the air friction and/or reduces the amount of energy drawn for the recharge). So this way, as explained above, for example when going downhill in this state the user can preferably for example set a desired cruise speed which is preferably maintained automatically by the car's computer, but preferably fro example pressing the drive pedal or the brakes pedal preferably increases or decreases the speed in ways that preferably at least initially preferably don't need to activate the electric drive or to press the brakes. And for example 24/12/08 Yaron Mayer & Haim Gadassi 143/304 when driving in a plane this means that for example if the driver takes of his/her leg from the drive pedal and does not press the brakes (for example when nearing a red light) preferably the car's computer for example automatically disengages the power from the engine, so that the engine preferably automatically simply rotates along with the wheels, thus allowing the car to gradually slow down but without wasting energy, unlike a normal gasoline car in which such driving still causes the engine do automatically draw gasoline even while slowing down (and as explained above this can preferably be done for example also in normal gasoline for example by automatically activating neutral mode - as explained above)(however this is preferably not done for example when the user is going up a slope, so that the car does not start unexpectedly to fall backwards, and/or for example the computer allows the slowdown like this eve for example when going downhill by preferably automatically for example engages the brakes or engages the engine gain if the car starts falling backwards).

Another problem is that for example people who had previously driven an automatic gasoline car expect that after removing their leg from the brakes from a stopping position for example after the traffic light changes from red to green, the car automatically starts moving slightly forward, whereas normal electric vehicles do not behave this way (however for example a person who's starts driving on an electric vehicle as his/her first car would not expect such a behavior until pressing the drive pedal). So preferably this is improved so that the user can for example enable or disable this behavior for example by selecting the desired mode and/or for example can also determine the speed or amount of effect in this mode, and if this is enabled the car's computer preferably automatically activates the power to the engine with the desired initial speed after the user removes his/her leg from the brakes. Anther possible variation is that even without this mode preferably if the driver is for example uphill and wants to start moving and removes his/her leg from the brakes, preferably the car's computer automatically keeps the brakes really on and/or for example otherwise temporarily locks the wheels and/or the engine until the user presses the drive pedal and the engine starts moving forward, thus automatically preventing the car from sliding backwards (this is preferably done only for example when in driver mode, so that for example in Neutral or similar mode the car can slide backwards in this case as expected). Another problem is that people who are used to starting a car by turning a key can find it very unusual and confusing to start the car for example by pressing a button instead of turning a key, and also have normally no auditory feedback that the engine has been started, and also a car in which no key is needed for starting the engine is less safe against thieves since they only need to get passed the doors. So preferably this is improved so that the user needs to turn a key like in a normal car in order to activate the engine, and preferably this is also accompanied for example by default or as one of the options by a simulation of an ignition sound and/or preferably also a simulation of at least some engine humming sound, which is preferably correlated automatically for example by the car's computer with the actual results, so that for example if there is for example some problem or delay preferably the ignition sound and following preferably humming sound are preferably delayed until the car is indeed in the equivalent condition (for example through internal and/or external speakers), which preferably the user can also choose for example from a set of 24/12/08 Yaron Mayer & Haim Gadassi 144/304 available sounds and can preferably also for example adjust its volume, for example like choosing the other possible simulated sounds, as explained elsewhere in this patent application. In addition, eventhough a normal electric car typically has no mechanism to disengage the engine from the wheels, preferably the car has a drive stick with at least 4 states: Park, Drive, Neutral and reverse, like in a normal gasoline automatic car, and when engaged in neutral preferably the engine simply rolls along with the. wheels and/or the car enters the simulated neutral mode as explained above, and/or for example in neutral mode the engine can also be really mechanically disengaged from the wheels. Another problem is that for example if the car had an accident or for example there is a serious malfunction of the computer or of the electrical system and the car needs to be towed, if for example at least 2 wheels in the electric car are always be engaged mechanically to the engine, towing the car might generate currents which might further damage the electric systems. So preferably this is improved so that the user can for example manually disengage some of the electric connections for example before towing the car, or for example the electric car has a special mode in which the engine can be mechanically disengaged from all the wheels.

Another possible variation is that for example if the car already has slope sensors (and/or for example in normal cars), preferably these can be also used for example for sensing if the car is parked in a place with a slope beyond a certain threshold, so that for example in places with such a slope or bigger (and/or for example in smaller slopes or even for example when there is no slope) preferably the car's computer can preferably for example automatically engage the handbrake (or for example a similar internal electrically controlled braking device and/or for example the normal brakes and/or for example another wheel and/or engine locking mechanism) for example when the user parks or turns off the engine, and preferably the car's computer automatically lowers or releases the handbrake or other device and/or locking mechanism again for example when the user starts to drive again.
Another possible variation is that preferably the brake or other locking mechanism is automatically locked mechanically when the user does what he/she has to do to stop the car and turn off the engine even for example if the car's computer or battery is for example empty or not working and even if the car has no gear, and when starting to drive it is preferably opened automatically by whatever the driver has to do to start the car and/or automatically by electric control. This is important since for example in electric cars without a gear, the car would be otherwise considerably less stable in parking than a normal gasoline powered car. Another possible variation is that preferably the car has sensors that can sense or make sure for example if the recharge cable is still connected (this is preferably a separate for example electrical and/or mechanical sensor apart from the communication with the recharger or recharge post, since there might be for example a communication block, but basing the sensing for example on checking if there is still for example power on the cable is less preferable since for example the recharge plan might have already ended but the cable might still be connected, so preferably the sensing is mainly mechanical as explain below), so that preferably if the user for example tries to start the engine or for example if he/she tries to start to drive while the cable is still connected, preferably the car's computer automatically issues a warning and/or preferably locks the car so that the user preferably cannot start driving while the cable is still 24/12/08 Yaron Mayer & Haim Gadassi 145/304 connected and/or for example the preferably small door of the cable or socket compartment is still open, and/or for example the if the cable is inserted from the recharger or recharge post into the car, for example the car computer is able to automatically disconnect the cable, which then preferably automatically retracts for example when the recharger or recharge post senses that the cable is no longer connected. So for example if the cable is inserted from the recharger or recharge post into the car preferably for example the car computer can sense for example if the cable is still plugged in for example in full or partially or for example some preferably small door has to be opened in order to insert the cable into the car's socket and the computer can for example sense if the door has been closed and can for example warn the user and/or refuse to move the car until this door is closed and for example the door can be closed only after the recharger's cable has been removed, and on the other hand for example if the cable is inserted from the car into the recharger or recharge post then preferably the car computer can sense for example if the cable has not been rolled back, or for example the cable comes out of a chamber with a door that has to be opened and for example the car computer can sense if the door has been closed and warn the user and/or refuse to move the car for example if this door has not been closed, and preferably the door can be closed only after the cable has been fully pulled back into its chamber. (Another possible variation is that for example the warning can also be issued for example by the recharge post, for example by auditory warning, but that is less preferably since t means that the recharge post would have to sense if the car has started to move). On the other hand if for example the preferably small door of the cable or socket compartment becomes open for example by mistake or due to malfunction while driving, which means that for example if the small chamber contains a cable the cable might dangle outside, preferably the car computer warns the user but without automatically stropping the car, since automatically stopping the car while already driving might be dangerous, but this is not supposed to happen at all since preferably for example the car computer and/or for example some mechanical mechanism and/or for example some other electronic mechanism, preferably automatically locks the preferably small door of the cable or socket compartment while driving so that for example even if the user presses by mistake the lever that is supposed to open it, preferably it remains locked if the car is in the middle of driving or for example is moving beyond a certain threshold speed. Another possible variation is that for example even after opening the lever that opens the preferably small door of the cable or socket compartment, preferably the user still has to go out and move some additional mechanical or electric lock on the outside before the small door can actually open. Another possible variation is to add similar safeguards for example also in ordinary fuel car, for example when trying to start to drive while the fuel pipe is still connected to the car or if the user for example presses by mistake the lever that opens the gas tank door. Another possible variation is that for example the plug has for example at least one pin or some pins of different lengths (and/or for example similarly the inner metal connector in the socket is shorter in that hole or holes), so that when pushing the plug in or pulling it out the connection is created or terminated in a certain sequence, so that for example no high voltage can go through if the cable is not fully plugged in (so that for example when pushing the plug in first of all for example the power lines are connected but for example some control line or for example the data line, which preferably have a shorter pin 24/12/08 Yaron Mayer & Haim Gadassi 146/304 and/or for example enter into a whole with a shorter connection on the side of the socket, preferably become connected for example only after the high power pins are in place and the recharger or recharge post preferably does not do anything until for example the control line or the data line is in place and/or for example the high power is used only after the recharger or recharge post has verified that all the pins are connected and/or for example has sensed mechanically that the plug is fully in place, and for example when disconnecting the cable the control line or the data line are similarly the first to be disconnected, and for example when it is disconnected it automatically causes the recharger or recharge post to stop sending power on the power lines even if for example the plug was somehow pulled out before time by mistake, which means also that preferably only a compatible plug can be used (as explained also elsewhere in this application this is preferably done for example by an appropriate automatically controlled internal power switch and/or microcontroller for example within the pole of the recharge post)). Another possible variation is that there is for example an automatic switch for example at the surface of the socket for example between the holes or for example at the edge of the plug which for example operates with a spring and is closed only when pressed, for example like in a keyboard, so that for example the switch is turned on only when the plug-in has been pushed in the socket till the end, and so even after for example all the pins already touch the connection the recharger or recharge post for example won't do anything or at least won't send high power until the switch is closed, and similarly for example when pulling the cable out first of all the switch is opened (but this is less preferable since such a switch can be less reliable than a shorter pin or shorter connection). Another possible variation is that for example after inserting the plug the user for example has to rotate the plug together with part of the socket in order to lock it, but that is less preferable since users might forget to rotate it or for example use too much power or for example rotate too little, and since anyway the plug can be locked in the socket for example by one or more pins or other elements that automatically enter for example from the sides of the socket for example into side holes in the plug (i.e. preferably in an area that is within the socket) or for example pins or other elements that cover it after it has been inserted (This covering can be done for example externally or for example the plug is preferably wider at its end or for example has one or more slits for example around it and for example after it is inserted for example one or more pins or hooks or for example semi-circles or other protrusions automatically lock it in position preferably from within the socket), and such a lock can be used anyway, regardless of if the user needs to turn the plug or not. Another possible variation is that the lock can still be opened anyway and/or the plug can be removed anyway and preferably in a way that does not cause damage for example to the cable or to the socket or to the plug or to the lock - preferably for example by using excessive force of for example 10 Kilograms or more or other reasonable threshold - so that for example if someone bumps into the cable (for example while running) and/or otherwise creates a strong pull on it or for example if someone tries to pull it out by force, preferably the lock can still be opened and/or the plug can be removed instead of causing damage for example to the cable or to the plug or to the socket or to the lock. Preferably this is done for example by using for example flexible for example metal semicircles or other preferably flexible protrusions or shapes or elements for example inside the socket, or for example if the plug is locked in place for example by hooks or similar 24/12/08 Yaron Mayer & Haim Gadassi 147/304 elements that close on it for example from the sides on the outside preferably these elements are flexible enough so that for example by using sufficient force preferably the locking elements can be forced to bend or retreat preferably flexibly thus allowing the plug to be released, and/or for example there are sensors in the plug that can determine the strength of pulling (for example based on piezo-electrics or for example based on a switch that gets for example pressed or for example unpressed for example after the flexible elements become sufficiently bent or for example by infrared or other sensors of the amount of movement) and can thus for example trigger an emergency release of the lock for example if the force exceeds the preferably pre-defined threshold, and/or for example at least after the plug is removed preferably the recharge post senses that the cable has been removed and preferably automatically releases the lock (therefore either way preferably if the cable is forcible removed preferably the lock is automatically released during the removal or afterwards, otherwise it might be very difficult for example to insert again the same plug or for example another plug), and/or preferably for example there are also for example sensors for example for pressure for example sideways and/or for example the socket walls are sufficiently flexible, so that for example the plug can be also pulled out for example if sufficient force is used for example to the side or for example diagonally and for example not only if the force is applied for pulling the cable straight out. In addition, preferably the cable is internally strengthened for example by one or more steel wires which preferably go through the entire length of the cable and preferably hook strongly into the plug, so that for example even pulling by force does not damage the cable and does not for example pull the cable out of the plug. However preferably if the cable is forcibly removed for example this way (for example by design or for example even if it happens without specially designing for this), preferably for example the recharge post starts to flash for example with for example red light and/or for example makes auditory warnings such as for example strong beeps or for example alarm sound or for example synthesized or pre-recorded speech which for example warns against this -preferably for example while the force is being applied even before the plug actually disconnects and/or preferably also after the plug is disconnected, and/or for example the recharge post also notifies the car computer for example about the attempt to unplug the cable by force (and/or for example the car computer senses the attempt and/or the release directly and/or for example is involved in allowing for example the emergency release for example if the cable comes from the recharge post into a socket in the car since in that case the mechanism that locks and releases the plug is preferably in the car, as explained also elsewhere in this application) so that the car computer can for example automatically sound the car's alarm and/or for example the car computer similarly sounds the alarm for example if it senses that the cable has been illegally disconnected - i.e. for example without an authorized command to release the lock (for example at least for 30 seconds or 1 minute or other reasonable time). On the other hand, if the cable is flexible and/or extendible enough, such as for example by using a spiral cable (for example like a phone cord but preferably with a larger diameter of the spiral - such as for example a few centimeters or more, as explained also elsewhere in this application) and/or for example using a cable which is for example flexibly extended for example from a wheel or reel or roller for example in the car and preferably controlled for example by the car computer (if the cable comes out of the car) or for example in the 24/12/08 Yaron Mayer & Haim Gadassi 148/304 recharge post and preferably controlled for example by a microprocessor in the recharge past (if the cable comes out of he recharge post)(wherein the roller or reel or wheel is preferably controlled for example by a spring or for example by an electric motor, as explained also elsewhere in this application), it might be unnecessary to allow forceful removal for example if the flexibility of the spiral and/or of the roller is sufficient for example to deal with pulls caused for example by accidentally bumping into the cable, but preferably both the flexibility and the forceful removal ability are used for example as a failsafe safety mechanism.
Preferably if such a roller or reel or wheel is used for example in the car (if the cable comes out of the car) or in the rechalrge post (if the cable comes out of the recharge post), preferably it is controlled by an electric motor preferably together with sensors that can sense for example the amount of pull on the cable for example by a similar mechanism as in electronic weights and/or for example by amount-of-twist sensors (such as for example by connecting the motor to the reel or wheel for example through a rubber tube or for example through a metal spring or similar devices), so that preferably for example the electric motor automatically preferably becomes locked for example mechanically at a certain position after the cable is plugged-in but the lock is preferably with a low force (for example slightly above the force needed to hold the cable's weight sufficiently above ground) and/or for example based on a flexible elements (such as for example one or more.
preferably flexible blades for example of thin rubber) so that for example a force above the resistance threshold automatically releases the mechanical lock, and/or for example when there is a pull on the reel or wheel or roller preferably the motor can preferably instantly release the reel or wheel at a speed that preferably matches the amount of the pull so as to keep the resistance preferably constant or for example with gradually increasing resistance for example in a way that for example simulates a spring, and/or for example the reel or wheel itself preferably has a sufficient amount of friction to release the cable gradually. Another possible variation is that for example after the cable is plugged-in preferably the computer for example takes into account the cable's weight and/or for example the known height of the cable compartment's door and of the socket and/or for example other known parameters and preferably pulls the cable back automatically a little with sufficient force so that there is sufficient slack in the cable but preferably the cable is sufficiently above ground, and preferably according to the amount of pull on the cable after plugging-it and the length of cable out, preferably the computer can also calculate for example also the distance for example between the cable compartment door and the socket, and thus can preferably even better control for example the speed and/or amount of resistance when releasing the cable for example if it is suddenly pulled (for example if someone bumps into the cable) while preferably also preventing for example the cable from touching the ground (preferably in order to avoid for example getting the cable for example dirty with mud). As explained also elsewhere in this application, preferably if the cable is spiral but for example with a relatively small diameter of the spiral (such as for example only up to a few centimeters or less in diameter) preferably it also is for example rolled on such a reel or roller or wheel, for example like a non-spiral cable, for example in the car or in the recharge post.
Preferably in addition preferably if the cable is released without receiving the normal command to release the lock, preferably the car computer and/or for example the recharge post preferably automatically also notify the service provider, and/or for example the car 24/12/08 Yaron Mayer & Haim Gadassi 149/304 computer or the service provider's main computers preferably for example send the user an automatic warning that the cable has been disconnected, for example by SMS or instant phone call and/or for example Instant Message or for example email or other remoter means, as explained also elsewhere in this application.
Another possible variation is that for example the plug is not locked but for example removing it without authorization for example causes the car alarm to go off and/or the automatic messages to the user as explained above, but that is less preferable.
Another possible variation is that for example the ability to release the plug with a certain amount of force can preferably be remotely enabled or disabled for example through software control that responds for example to a remote command for example from the service provider's main computers and/or for example the definition of the threshold amount of force needed can also be similarly remotely changed, so that for example in some neighborhoods for example this feature is for example enabled or disabled or for example set to a different force threshold for example based on the type of the neighborhood - for example if it is a good quiet neighborhood or for example a neighborhood in which for example kids tend to pull cables out or for example a rough neighborhood where there have been cases of vandalism - i.e. for example pulling the cable or the plug in a way that tries to damage it.

In addition, as explained also elsewhere in this application, preferably while recharging the plug becomes physically locked, for example by an automatically controlled mechanical part which closes in on it for example from the side (which has safety advantages and preferably prevents other users from removing the plug without authorization). Another possible variation is that for example when the user starts to drive and/or for example while driving, the car computer can for example sense for example by external light sensors for example if at the current level of darkness outside the car for example it is recommended or required to light the lights and can preferably for example remind the user to turn on the light for example by visual and/or auditory indication (for example by sounding a pre-recorded message or synthesized speech), and/or for example can turn on the lights automatically and preferably the user can choose (for example through some switch or through the computer interface) if in such situations the car will just remind he/her or automatically turn on the lights and/or for example the user can also disable this feature. Another possible variation is that for example the normal car lights (preferably in addition to the high lights) can preferably be operated in more than one level, so that for example the user or the car computer can for example decide if to use for example one of 2 or 3 levels or for example the power or voltage to the lights can be changed in a continuous way. Another possible variation is that for example similarly in airplanes (preferably especially in passenger airplanes) preferably for example the airplane's computer preferably senses for example if the plane is about to land but the pilot for example forgot to lower the wheels (for example by altitude sensors and/or sensors that can determine the proximity to the ground surface, such as for example by laser, ultrasound, and/or other known means), so that for example if the distance to the ground is below a certain safety threshold that leaves sufficient time to respond manually the computer can for example issue an automatic warning to the pilots and/or automatically lower the wheels, and/or for example first one or more warnings are automatically activated 24/12/08 Yaron Mayer & Haim Gadassi 150/304 and for example if no response is made for example within a certain time limit and/or for example the distance to the ground reaches for example a second threshold, the wheels are preferably lowered automatically. Another possible variation is that for example if there is a malfunction and the wheels cannot be lowered, preferably the airplane has for example additional emergency wheels or rollers, which can be for example smaller or even for one-time use but can preferably be lowered or exposed preferably automatically in case of emergency.
Another possible variation is that preferably if the place has already landed and the wheels have touched the ground preferably an automatic system which is preferably for example run by the plane's computer and/or for example by other electrical and/or mechanical means preferably automatically locks the wheels in their current state extended state so that if a pilot for example tries to fold the wheels again by mistake preferably for example the computer and/or for example some other electronic or mechanical system preferably automatically prevents it for example as long as the plane is not again above ground.

Preferably one of the main renewable energy sources for electric cars will be based for example on Sharav Sluices (Arubot Sharav) for example of the type suggested by Professor Dan Zaslavsky from the Israeli Technion (which is based on improvements and expansion of the original idea by Dr. Phillip Carlson), which are downdraft energy towers which are preferably located in hot dry areas near the sea, in which electrical energy is created by spraying sea water at the top of a tall hollow cylinder (which according to Prof. Zaslavsky is preferably around 1000 meters high and with about 300 meters diameter), thus cooling hot air and causing it to move down in the tower, so that it pushes multiple wind turbines around the bottom area, which according to Professor Zaslavsky can become one of the most efficient sources of renewable energy. However, preferably these towers are further improved, so that for example the tower becomes at least internally thinner as the air goes down, thus forcing increase in the air's speed, and/or for example air ducts that lead to the turbines at the bottom preferably become thinner as they approach the turbines. Another possible, variation is that preferably the system can for example automatically or through manual control for example close or for example gradually decrease or increase the air passage to one or more of the turbines and/or can for example change the shape of preferably flexible air shafts for example by moving mechanical arms or for example changing the shape of rings that surround them, thus enabling changing the configuration, for example based on temperature, wind speed, and/or other relevant parameters. Another possible variation is that preferably for example at least some of the turbines are optimized for example for higher wind speeds and some for lower, and the system preferably takes this into account for creating preferably automatically a preferably optimal combination of for example which and how many turbines to deploy each time for example based on the current downward wind speed and/or for example temperature and/or other relevant parameters. Another possible variation is that preferably instead of or in addition to using some of the generated energy for desalination of part of the sea water that is used in the system (as suggested by Prof. Zaslavsky), preferably the system is improved so that it can use the spraying of water droplets that cools the air at the top of the tower also for example for creating direct desalination of at least some of these water droplets - for example by using at least some water droplets of the right 24/12/08 Yaron Mayer & Haim Gadassi 151/304 size and speed at least over part of the area so that they evaporate briefly and immediately re-condense in a way that enables separating the water and the salt in the air, for example in a way similar to this type of desalination process as explained in other patents by the present inventors. Preferably water droplets that have been directly desalinated this way while cooling the air at the top of the tower are preferably captured separately from falling salt or other salt water and are preferably conducted separately down to a container of desalinated water, and/or for example if at least some water droplets only recondense lower down the tower (for example due to high humidity conditions in the air at the top of the tower), preferably the different spread of water particles and salt particles in the air (for example due to their different weights and/or sizes and/or shapes) is taken into the count for example for positioning various collector elements, so that preferably at least some of the recondensed water droplets can be collected separately from the salt particles.
This has the further advantage that preferably different energy considerations can be taken into account than in systems that only desalinate water droplets this way, since the water droplets are needed anyway for cooling the air, and thus what might be a waste of energy in a stand alone desalination system can be used as part of the normal procedure in the Sharav Sluices. Another possible variation is that preferably there are also for example at least some wind turbines also for example at or near the top of the tower or for example at the external sides of the tower for example at various heights and/or directions (for example hooked on sideways extending poles that come out of the tower sideways in various directions, and these poles can preferably also rotate for example sideways as needed) - for example in order to capture also energy from sideways winds that pass by.

Another possible variation is that for example on various building roofs energy is collected for example both from solar panels and from wind turbines, and preferably for example at least some of the turbines and/or at least some of the solar panels are connected to automatic tracking systems that can automatically change their tilt so that preferably both the position of the sun and the direction of the wind are taken into account and preferably also the interaction, so that for example either the pole on which the turbine is located and/or the solar panels can change their tilt in a way that the turbines don't cast shadows over the solar panel or at least reduce the amount of shadows.

Another problem is that for example in mechanical parking duplicators, which enable 2 or more cars to park on the same area on top of each other, there is a danger of killing for example a child or an animal if while moving the platform down they suddenly move into the area where the frame is moving down and there is a danger of the driver and passengers of the lower car becoming locked up by mistake underground if for example while moving the car into the lower platform someone else activates the down movement of the platform. So preferably this is improved so that for example if someone gets trapped by mistake underground he/she can move the platform up again from the underground position for example by pressing a button in the underground position which activates the up-movement (so that preferably there is at least one such button preferably at each underground car position, or for example one such button if the same platform lift is used for moving for example 2 or more bottom cars and 2 or more upper cars), and/or for 24/12/08 Yaron Mayer & Haim Gadassi 152/304 example the driver' has also a remote control which can preferably by electromagnetic signal give the command to uplift the platform, and/or for example there is at least one underground alarm button preferably per each underground space, which preferably sounds an alarm in the building and/or an automatic phone call to a service station, which can be used for example if there is a malfunction which does not enable the platform to move up (so preferably there is both a move-up button and an alarm button in the underground position). In addition, preferably the platform contains automatic sensors that can automatically preferably instantly stop its downward movement when there are obstacles in its path - for example based on ultrasound and/or laser and/or infra red and/or electromagnetic and/or electric field induction and/or for example mechanical sensors which are for example pressed based on contact. Preferably this can be done of course for example both with electric cars and with normal cars.

As explained also in the Glossary section, various combinations of the above and/or other variations can also be used, which means also possible sub-combinations and/or separations of elements in them.

Important Clarification and Llossarv:
All the drawings are just exemplary diagrams. They should not be interpreted as literal positioning, shapes, angles, or sizes of the various elements.
Throughout the patent whenever variations or various solutions are mentioned, it is also possible to use combinations of these variations or of elements in them, and when combinations are used, it is also possible to use at least some elements in them separately or in other combinations. These variations are preferably in different embodiments. In other words: certain features of the invention, which are described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention, which are described in the context of a single embodiment, may also be provided separately or in any suitable subcombination. The above rules of course also mean for example that throughout the specification, including the claims, the words "all" or "each", such as for example "each computer" or for example "each apartment" or "each end node" or "each recharger" or "each 24/12/08 Yamn Mayer & Haim Gadessi 153/304 car", or other word combinations that contain the word "each" or similar words, do not mean necessarily all the items but can mean simply individual items in general or some of them, i.e. it can be for example a general rule, but not necessarily without exceptions. Through the patent, including the claims, where fast batteries are described it can be also for example super capacitors or other fast recharge devices. Through the patent, including the claims, the words "main computers" mean for example computers or central computers or servers which serve multiple clients, and can mean plural or singular.
Similarly the words "car computer" can mean plural or singular, since typically the car's actually contains a bunch of multiple computers of various types. Similarly for example the words battery or batteries can mean for example plural or singular. As explained also elsewhere in this application, the service provider can also be for example at least in some areas the electric company itself, so throughout the specification, including the claims, whenever the service provider is mentioned it can be also the electric company. Throughout the specification, including the claims, unless indicated clearly otherwise, the word recharger in general can mean for example the car's own recharger, the recharge post, or an actual recharger circuitry in the recharge post. The words passive recharger or passive recharge post mean a recharge post which does not contain an actual recharger circuitry. As is made clear in the specification, throughout the specification including the claims, the words "fast recharger"
typically mean a recharger which is typically at least a few times faster than normal rechargers, so that for example if a normal recharger can fully recharge the car battery or batteries for example within 4-8 hours, a fast recharger can preferably recharge the car battery or batteries for example fully or almost fully or for example 80% or more, for example in 1 hour or less or for example in 30 minutes or less. Throughout the specification, including the claims, the word mileage refers to distance in general, and of course not necessarily in miles.
Detailed descriution of the preferred embodiments All of the descriptions in this and other sections are intended to be illustrative examples and not limiting.

Referring to Figs. la-b, we show an illustration of an example of rerouting of the batteries in the electric car during the recharge in order to enable serial recharge with higher voltage and lower currents. As explained in the patent summary, preferably in order to enable faster recharge time of the cars, especially if for example the cars use Ml or similar fast charging batteries or other fast recharge devices such as for example one or more super capacitors such as for example EEStor, so that preferably a car can be recharged at the service station for example on the fly preferably in a few minutes, and preferably in order to solve problems such a huge current would create (such as needed very thick wires, and reducing huge amounts of heat from even 1% lost energy during the transfer), preferably the recharging can preferably be done at much higher voltages than the normal operating voltage of the electric car batteries, which are typically around 50 volts.
This is preferably done by electrical and/or mechanical switches and/or multiplexers in the car andJor in the array of the for example batteries used by the service station 24/12/08 Yaron Mayer & Haim Gadassi 154/304 to charge the car, so that preferably during recharge, the batteries (preferably both the car batteries that are being recharged and the for example batteries that are recharging them) are preferably automatically preferably reconnected serially instead of in parallel, so that for example if there are 20 50-volt batteries or battery modules in the car, preferably during recharge at the service station or for example at home these batteries and/or elements (for example internal cells) in them and/or at least some of them are preferably connected serially, so that they can be recharged at preferably for example 1000 volts or even more (or other convenient high voltages), which means much less current, less need for ultra thick wires even at high speed recharges (preferably both in the car and in the external recharging interface), and much less problems of heat from the typical 1% loss of energy during the recharge. Similarly, preferably while the station is recharging their batteries outside of cars (for example their own batteries and/or accumulators and/or superconductors that are preferably charged for example mainly at night hours to be used for later recharging car batteries during the day) and/or while recharging car batteries which are replaced for the recharge, preferably this recharging at the night time is preferably also done in serial batches of preferably a least 1000 volts (or other convenient high voltages), for similar reasons (preferably by connecting serially batteries of multiple cars for recharging together at the same time).
Similarly, if for example cars with Ml batteries or similar fast recharge batteries or other batteries or other fast recharge devices such as for example one or more super capacitors such as for example EEStor are recharged also for example at the homes, preferably mainly during the night hours (and/or for example in offices where the car is typically parked during the working hours), preferably the same or similar electrical and/or mechanical switching and/or multiplexing mechanism can be used for example for creating preferably the most optimal voltage conditions for the relevant power supply, so that for example in areas like Israel where there is a power supply of 220 volts in normal connections and around 400 volts if a 3-phase connection is available, preferably the batteries can be for example preferably automatically switched in a position of for example part parallel and part serial (for example some batteries are connected in parallel in some serially and/or for example other concurrent types of combinations are used) and/or connected serially with a proper voltage adjustment and/or other electronic compensation and/or conversion (preferably the rerouting to serial or part serial connections enables using the available voltage without a need for transformers, which would increase wastes and make the recharger more expensive), so that preferably they can be recharged most efficiently at the home for example with for example 220 volts in 1-phase systems or for example around 400 volts in 3-phase systems, and for example in the US
where the typical electric outlet voltage is half of that, preferably the batteries can be again preferably rewired accordingly during the recharge, preferably automatically, and similarly if the recharging in the service station can be done for example with 1000 Volts or more, then the serial routing is changed accordingly for that, preferably automatically, as explained above. This rewiring is preferably done through computerized control so that preferably the user can enter for example on an LCD console for example the available voltage value and/or the duration of time available or desired for the recharge and/or for example the maximum amperage desired or available during the recharge, and/or for example more preferably the recharger senses the available voltage automatically, which is also safer in case the 24/12/08 Yaron Mayer & Haim Gadassi 155/304 user might give the wrong voltage parameter by mistake (for example by analogue means and/or by digital communication with the recharger), and then preferably the computer that runs this in the car recharger preferably first moves the switches and/or multiplexers and/or other electrical controls to the appropriate configuration and preferably only then makes the connection and/or allows the recharging current to start flowing, and preferably controls the rate of the recharge for example through PWM or other known means. If for example the car contains only a single large and/or powerful battery (or for example only few more powerful batteries than the typical preferably about 20 batteries, such as for example 5 or less), then preferably the battery itself (which would typically contain multiple cells of smaller voltage internally) preferably contains appropriate mechanical and/or electrical switches and/or multiplexers (and/or for example chemical means) internally in order to enable this switching internally so that preferably internal elements within the battery can be switched to become connected more serially during the recharge of the car batteries (compared to during normal operation), and if multiple batteries are used then preferably these mechanical and/or electrical switches and/or multiplexers are included in the housing of the batteries in the car. As explained above, the appropriate serial rerouting for recharging and/or the rerouting back to for example parallel or partly parallel connections after the recharging are preferably done automatically for example after the recharge connector unit senses the voltage (for example 3 phase or normal, as explained above), and preferably the car computer or the recharger's processor automatically preferably issues the command for rerouting accordingly before allowing the circuit to close and the recharge to begin. So for example if the electric car has 2 sets of battery stacks (11 a &
11b) (in this example the batteries in the first stack are marked as 1.1 and the batteries in the second stack are marked as 1.) in which for example during normal operation each stack is composed of a number of serially connected batteries or cells which produce for example 250 or 300 or 350 volts, so that for example these stacks work together in parallel with each other in order to boost the current (or for example one or more stacks are activated only when the car is accelerating), so when recharging the stacks serially if there are for example 2 stacks then the recharging voltage can be for example 600 or 700 volt and if there are for example 3 stacks then the recharging of all the 3 stacks can be done for example at 900 or 1050 volt (which can be done for example at the service station or preferably for example also at special street recharges), and for example if recharged at home the stacks in this example can remain parallel.

Referring to Fig. 2, we show an illustration of an array (20a) of serial recharges (1-42 in this example) which can each recharge serially a preferably more or less homogenous group of batteries, wherein the multiple serial rechargers are preferably stacked together for example in parallel preferably both sideways next to each other and to the height - one above the other, to allow better use of the available space.
Eventhough the drawing does not show it, preferably there are certain spaces between the serial recharges vertically and/or horizontally and preferably there are automatic conveyor belts which control the arrival and removal of the batteries and their positioning in the serial rechargers, so that preferably these spaces enable heat dissipation, spaces for conveyor belts, and/or room for maintenance work when needed.

24/12/08 Yaron Mayer & Haim Gadassi 156/304 Referring to Figs. 3, we show an illustration of a flowchart of an example of the efficient processing and recharging of replaced batteries in service stations.
As explained in the patent summary, preferably while recharging the batteries serially preferably the recharger takes into account various measurements and/or various relevant parameters of the individual batteries or elements which are being recharged serially, such as for example their temperature and/or age and/or voltage and/or their behavior during the recharging, and preferably adjusts the recharging parameters (such as for example the voltage, current, pulses and/or duration of the recharge) preferably according to the weakest battery or element in the series.
Preferably each battery or relevant element contains a microchip which automatically determines or measures the relevant parameters, preferably including also for example how much current went in and out of the battery during its lifetime and/or for example how many times it has been already recharged, and preferably these microchips can communicate the information about the relevant parameters preferably digitally to the recharger. As is also shown in steps 3.1-3.8, when such electric car batteries are replaced and recharged at the service station, preferably the batteries or relevant modular elements are preferably automatically sorted by the relevant parameters (preferably by one or more computers which read the parameters automatically directly from the relevant microchips and sort them for example by automatically dropping the batteries over different conveyor lines), so that preferably they are grouped automatically into preferably more or less homogenous groups, so that batteries or elements which are in a similar state or have similar relevant parameters are preferably grouped together, and then preferably each group is recharged separately (preferably in a separate serial row for each group and preferably the recharging in each group is for example optimized according the average parameters of the group or for example according to the weakest batteries in the group) in order to improve the efficiency of the recharging of the batteries in that group. So for example if an average service station services for example on average around 1,000 cars per day and if for example each car contains for example around 20 batteries, this means that for example the service station preferably has for example at least 200 parallel productions lines which can each for example recharge for example up to 100 batteries serially (or for example 100 production lines that can each for example recharge for example up to 200 batteries serially, or for example 400 production lines that can each for example recharge for example up to 50 batteries serially, or other reasonable combinations), so that preferably for example the entire 20,000 batteries can be recharged together at the same time, preferably during night hours, and so preferably for example if each battery has for example a voltage of 12 volts, this means that each group of for example around 100 batteries is preferably recharged for example at around volts or for example each group of for example around 150 batteries is preferably recharged for example at around 1800 volts or for example if each battery has for example a voltage of 12 volts, this means that each group of for example around 100 batteries is preferably recharged for example at around 1200 volts, or for example if each battery has for example a voltage of 50 volts, this means that each group of for example around 40 batteries is preferably recharged for example at around 2000 volts. This way there is the advantage that preferably a much smaller number of rechargers is needed compared to when recharging each individual battery or cell or unit separately, and there can be much less current and heating and losses problems, 24/12/08 Yamn Mayer & Haim Gadassi 157/304 and yet each homogenous group can preferably be recharged almost optimally.
The multiple parallel series production lines are preferably stacked preferably both sideways next to each other and to the height - one above the other, to allow better use of the available space. After the recharging preferably the batteries are automatically collected preferably in a way that preferably mixes together batteries of the different groups in order to improve the statistical behavior of the batteries in the car, so that for example when the recharged batteries are inserted back into cars that come for service for example the next day preferably there is a good mixture of batteries from various groups, for example by random mixing or for example by automatically collecting for example each time one battery from each group for example while choosing automatically an order that creates a good mixing, which is preferably done for example by another computer or computers or for example by the same computer or computers that also sort incoming batteries into groups when they arrive for recharging. Of course, if the car for example uses only one main large battery of for example 380 volts then there in no such heterogenic mixing, and preferably cars get batteries which are more or less fully recharged and/or with higher or lower capacity preferably based on their priorities, as explained elsewhere in this application.

Referring to Fig. 4, we show an illustration of a flowchart of an example of a preferable recharging process for example at a public recharger or recharge post. As can be seen from the drawing, preferably the Electric Car arrives at the recharging post for example after locating a vacant recharging post or for example after getting automatic directions to it and/or reserving it in advance for example a few minutes before arriving at it (4.1). The car and/or the user is preferably identified automatically for example through a preferably encrypted digital ID of the car (and preferably also a similar ID of the battery) which is for example communicated automatically when connecting to the recharge post and/or for example the user inserts or passes a smart card or other card or other device through the recharge post and/or for example can use his/her cell phone (preferably by using short range direct communication with the recharger for example through Bluetooth or UWB), and/or has to enter for example a password or secret code, and/or the car is for example identified through direct preferably encrypted wireless communication with the service provider's main computers (4.2). (Similarly, preferably the recharger or recharge post also has a unique digital ID which is preferably automatically communicated to the car and is preferably used by the system to identify it for example also in its communications with the main computers). The recharge post preferably gets the relevant car-specific and/or user-specific (so that for example two or more different users of the same car can have different profiles) data or history and/or statistics and/or special current needs and/or specific requests and/or other parameters for example through the car's computer and/or for example through the smart card and/or through the communication with the Service Provider main computers, and/or communicates the above data to the main computers and/or the car communicates it directly to the main computers. (Preferably the smart card can communicate or for example synchronize data with the car's computer for example automatically, for example through bluetooh or UWB for example when the user is in the car, and/or for example by plugging the smartcard physically in the car at least once in a while). The recharge post or a recharger which is for example 24/12/08 Yaron Mayer & Haim Gadassi 15$/304 in the recharge post or in the car preferably also receives from the central computers for example when the car connects to the recharge post or for example when the smart card is inserted or passed through the recharger or upon request to the main computers - for example the most recent update on the current state of rechargers for example globally and/or at the relevant location, and/or for example uses information which it already has from regular updates which occur for example automatically for example every few minutes or other reasonable interval. The recharger or recharge post preferably also gets for example the user's and/or the car's current credit status and/or service plan for example through the smart card and/or through the main computers and/or for example through its own local database, which is preferably periodically updated also about this, and preferably also checks for example in its own database or for example with the main computers for example if the car or the battery has been reported as stolen or for example if there is any other problem or important information about this car or user (4.3).
Preferably the recharger's CPU (i.e. of the recharge post or a recharger in it or an internal recharger in the car) and/or the main computers decide for example based on the current global load and/or the current load in the area and/or the current time and electricity rates and/or the car's priority compared to the priorities of other cars recharging at the same time and/or location and/or the specific user's current needs or requests and/or the number of available rechargers or recharge posts at the area -what is the most recommended recharge option or options, and then preferably decide automatically, or for example offer the user a choice of more than one recommended recharge option (defined for example in terms of recharge time, amount of energy, percent of filling of the battery, and/or for example available travel distance, preferably with some safety margin), and/or for example recommends that the user go instead to a nearby battery swap station (for example if the user needs to travel now to a far away town and these are peak hours), preferably together with associated costs or credit or debit points and/or for example the percentages or other measures of quotas used up for that month or other period (so that for example the driver can see what amount of free recharge for example at peak hours he/she still has for example for this month), and/or for example the display preferably also shows the driver the assumed departure time of the car and/or the assumed length of time that the car is expected to stay in the parking spot (preferably based on the normal statistics and/or patterns of the driver and/or of the car, and/or on week days programming and/or on special requests that have been entered as explained above) and then the driver preferably has to choose or confirm the preferred choice (and/or for example the estimated departure time or expected length of parking time) and/or for example can make various adjustments or for example goes to the recommended swap station or for example decides to decline or come back later (4.4). In addition, for example at this stage preferably the recharger or recharge post can for example also communicate to the user (preferably by sending messages which are displayed on the car's computer and/or for example on its own display) for example automatic messages which have been for example previously received for example from the main computers and/or for example are received automatically when the user's car ID or car type or for example battery type data is sent to the main computers - so that for example this way the service provider can for example communicate important news or for example special local or temporary deals (such as for example offering a special deal or reduction for 24/12/08 Yaron Mayer & Haim Gadassi 159/304 example in one or more local shops or restaurants or entertainment centers -for example if the user has parked in the parking lot of a shopping mall), or for example warnings to users or for example send specific messages which are relevant for example for specific users or cars or locations. Similarly, the rechrager or recharge post preferably also gets automatic updates for example if various or nearby swap stations are for example temporarily out of charged replacement batteries or are for example temporarily overloaded with cars waiting in line, etc., and can for example take this into account if recommending a nearby swap station. The recharger or recharge post then preferably updates the main computers about the driver's decision and the recharger starts recharging the car accordingly (4.5).
Preferably when the recharge is finished (i.e. the decided amount of recharge has been reached or for example the battery is full), the recharger preferably updates the main computers about its status and preferably for example the main computers and/or the car's computer and/or the recharger can for example notify the driver automatically for example through SMS to his/her cell phone or for example automatic voice message or for example email or Instant Message and/or through other means that the chosen recharge is finished. Preferably at least if for example there is shortage of recharge places or other drivers have requested the system to locate for them a free recharging spot in the area, the system can request the user for example to move his/her car to a nearby free parking spot (for example through SMS or automatic voice message or instant message or email), thus freeing the recharge place, preferably for extra credit or for avoiding debit points or extra charges for continuing to occupy the place after the recharge has completed and/or for example receiving a reduction for moving the car, and/or for example the recharger cable disconnects automatically, so that for example if the cable comes out of the recharge post it can disconnect from the car and can be connected to other nearby cars, and if the cable come out of the car it can disconnect from the socket, thus freeing the socket. Another possible variation is that for example the cable can be extended to nearby parking places and/or for example multiple cars can be recharged from the same recharger or recharge post at the same time, as explained in the patent summary. On the other hand, since as explained above in the patent summary preferably the system automatically tries to balance the rechrage loads, preferably if the car for example remains near the recharge post after the recharge is complete, which can be OK especially for example if there are more than enough recharge posts for example in the street or parking place, preferably the system can automatically for example decide to add for example later extra recharge even beyond the chosen recharge plan, for example if there is less load at a later time or for example if the car owner for example stays late and picks up his/her car later than planned, and/or for example a cheap recharge time has been reached or a cheap recharge opportunity has become available. In addition, preferably for example the rechargers or recharge posts and/or for example the service provider's main computers can preferably take into consideration for example also various fluctuations in the availability and/or in the offered price of electricity for example during daytime and/or for example even during night hours and/or can preferably for example preferably automatically negotiate various deals on the fly with the electric company based on these conditions, so that for example if due to fluctuations in the demand for electricity for example during various daytime hours the electric company has spare excess power that it cannot utilize efficiently but 24/12/08 Yaron Mayer & Haim Gadassi 160/304 these fluctuations are for example too small and/or too fast to enable for example temporarily closing down and/or powering up or down one or more generators or other power sources, and/or for example if a significant percent of the energy comes from renewable sources such as for example wind or solar power and there are various uncontrollable fluctuations in this power (for example due to changes in the wind that affect the wind turbines or for example changes in the amount of solar power for example due to the movement of clouds in the sky), preferably the electric company (and/or for example the energy provider for example if there is a third company involved that produces the renewable energy) can for example offer extra available energy to the service provider for example during daytime at a preferably sufficiently better price than the normal daytime rates or the normal rates for that hour or other time unit. However, in order to make this sufficiently attractive to the service provider so that for example the service provider will agree to use the extra energy for example during daytime even if the service provider for example already recharged more or less all or most of the electrical cars with the amount of daytime recharge which they needed (for example if the extra energy becomes available for example in the afternoon, for example around 4PM or, later, after the rechargers had for example sufficient opportunity for example to finish recharging even all or most of the low priority cars), preferably the offer can go as low as the night time rates, and then for example the service provider can preferably automatically decide for example to instruct the rechargers or the recharge posts to offer extra recharge to cars that are still connected to the recharge post, for example in the work area, for example at least for users that are regular subscribers for example on a monthly plan, thus reducing the amount of night recharge that will be needed for these cars at night, or for example if the offer of extra renewable energy is made at night preferably it can come even for example at lower than normal night time rates.
On the other hand if for example the offer becomes available earlier in the day, while the service provider still needs to recharge high priority cars or low priority cars, the reduction might be for example considerably less or for example the electric company or third party producer of renewable energy might not offer a reduction at all. Another possible variation is that for example the service provider has global deals for example with the electric company and/or for example with one or more third party renewable energy providers, so that for example various such statistics are taken into account and/or are for example automatically updated periodically for example based on the last month or other reasonable period, so that for example the service provider agrees in advance to cooperate and help balance such fluctuations, for example in return for global cuts in the rates for example during daytime and/or during night time, so that preferably the service provider typically gets lower rates than normal users, and thus can offer its subscribers for example additional added value for recharging through its services. These arrangements preferably enable the service provider for example to use for example the statistics about car priorities for example together with statistics about typical daily demand fluctuations for example in various hours, in order to plan more efficiently the recharging times of various cars for example according to their priorities and/or expected departure hours and/or other patterns and/or parameters and/or needs as explained above, and/or for example to adjust the recharge plan and/or recharge instructions and/or recharge strategy on the fly according to the real time conditions, and/or for example dynamic less predictable changes, such as for example changes in wind or clouds 24/12/08 Yaron Mayer & Haim Gadassi 161/304 (and/or for example even predicted changes), are preferably used dynamically preferably while taking into account the relative car priorities and/or other parameters, so that for example fluctuations of increases in power are preferably automatically routed for example first or mainly or fully to the rechragers which are currently connected to cars that currently have high recharge priority (for example by instructing the relevant recharges or at least some of them to start recharging these cars at a faster rate or higher capacity or power or for example to allow these cars more recharge than planned)(and preferably this power can be routed also to low priority cars for example if the high priority cars are already being recharged at the full capacity or full possible speed of the rechargers (or of the batteries) and there is still extra power and/or for example they have reached their planned recharge), and/or for example fluctuations that cause reduction in the available power are preferably dealt with for example by first instructing rechargers that are currently recharging lower priority cars for example to temporarily reduce the amount of power or rate of recharge for example to at least some of these cars or for example temporarily stop their recharge for example for a certain predefined amount of time or for example until receiving a new instruction (and similarly preferably for example if there is still need for reducing power consumption and the recharging of low priority cars has already been reduced to minimum, preferably the service provider can temporarily also start reducing the recharge speed of higher priory cars). Another possible variation is that preferably the main computers for example also update the rechargers or the relevant rechargers for example once in a while (for example very few seconds or every few minutes or other reasonable period) about the relevant availability and/or price fluctuations, so that for example at least in some cases rechargers are allowed to make their own decisions based on the change in conditions, but more preferably such decisions are made by the main computers and are sent to the rechargers as instructions, as explained above.
This also means that preferably the rechargers are capable of working in a preferably wide variety of recharge speeds, but preferably it has to be this way anyway since for example these same rechargers can preferably be used for example in peak hours at considerably lower recharge speed than for example when recharging in cheaper hours for example in the afternoon or at night. (As explained already elsewhere in this application these features can preferably work either way - regardless of if the recharger is inside the car or in the recharge post, and in case the recharger is inside the car it can for example receive these instructions for example directly from the main computers of the service provider and/or of the electric company, for example through cellular or other wireless communication, and/or through a data link with the recharge post, which can be for example a passive recharge post or for example a recharge post which contains also a recharger circuitry and contains for example both passive sockets and sockets for connecting cars without an internal recharger).
Another possible variation is that for example users can buy smart home rechargers or recharge interfaces which can preferably for example make similar automatic adjustments and/or deals with the electric company on the fly according to such fluctuations and/or based on a global deal with the electric company, thus preferably receiving for example also lower rates than the normal rates for at least some hours (for example compared to the normal rates at the relevant hours). Another possible variation is that for example when the user parks the car (for example when moving the gear into park position, for example as soon as the user has finished moving the 24/12/08 Yaron Mayer & Haim Gadassi 162/304 gear or drive controller into the parking position and/or for example a certain amount of seconds afterwards, which preferably the user can also adjust for example as one of the defaults, or for example after the user also turns off the engine and/or turns off the car key and/or for example removes the car key as explained also below) preferably the car computer can automatically remind the user (for example by voice, preferably for example by pre-recorded message or synthesized speech) and/or by visual indicator, for example to plug the cable for recharging the car - for example at least if the computer determines for example based on the usual drive patterns of the user and/or of the car and/or the time of the day (for example based on light sensors and/or for example based on the internal clock of the car, which can preferably also be automatically synchronized for example each time when the user connects to the recharge post or for example through direct cellular or other wireless communication with the main computers) and/or the location (for example based on GPS) and/or the state of the battery and/or other parameters that a recharge is recommended or required (but preferably, as explained elsewhere in this application, at least if there are sufficient recharge posts in the area, preferably users are encouraged to plug-in the car to an available outlet anyway even if they don't need recharge at that time for example in order to enable also the automatic services when needed), and/or for example at least if the computer determines for example through automatic short range wireless communication with the recharge post or for example through automatic optical identification of for example some standard visual marks on the street or parking spots and/or for example on the recharge post and/or for example short range Bluetooth or UWB or other short range wireless communication of for example 10 meters or a few meters distance or less or other reasonable distance or for example similar infrared communication that this is a parking place with a recharge post next to it (and/or preferably also based on the car's computer's database about the locations of swap stations and/or recharge posts, which is preferably updated automatically from the service provider's main computers for example on a regular basis and/or for example with additional detail when entering or nearing specific areas, as explained elsewhere in this application), and/or for example the car computer or the recharge post and/or for example the service provider's main computers can automatically remind the user to plug-in the cable for example by visual and/or auditory indicator and/or for example by an SMS
message to his/her cell phone or for example by wireless communication for .example to the user's remote lock (so that preferably the remote lock has also a receiver and can preferably sound for example an auditory and/or visual alert) for example if the user has parked the car near the recharge post but has not connected the plug-in cable for example after a certain time (for example within a certain amount of seconds or a minute or a few minutes or other reasonable time - for example from the time of putting the gear or drive control into parking or for example from turning off the car key or from example from removing the car key or for example from exiting the car or for example from locking the car for example with the remote control, and preferably the user can also change for example the relevant event and/or the time from it and/or for example the conditions for making the reminder for example as explained also below and/or for example the means for reminding him/her) and/or for example if the user starts to walk away for example beyond a certain distance (which can indicate for example that the user forgot to plug the car in), and/or for example if the user has not responded and for example 24/12/08 Yaron Mayer & Haim Gadassi 163/304 certain additional time has passed in which the car is for example near available recharge posts but has not been plugged in then for example the car's computer and/or for example the service provider's main computers (for example through the car computer or through the recharge post) and/or for example the recharge post can remind the user for example even after some time to plug-in the car, and/or for example as explained above the car computer preferably reminds the user to plug-in the cable (preferably through voice communication) preferably in advance when he/she parks the car preferably before he/she even exits the car (even though this might be annoying to some users), or for example when the user starts to show signs that he/she is about to exit such as for example starting to open the car door. This has the advantage that if for example the user has to open the preferably small outside door of the cable or socket compartment for example by pushing a button or handle or lever within the car, if for example the user did not push the relevant button or handle and starts to open the car door (or for example starts to get out of the car - but using the event of starting to open the car door is better because it might be more annoying to the user if the car computer starts to talk to him for example after he/she already has one leg out and because it can be more easily detected by the car computer for example by the same switch that typically detects that the door is even partially open for example for opening the internal lights), this means that it is almost certain that the user indeed forgot that he/she should plug-in the cable, so for example reminding the user at this stage has a very high chance of being done only if the user really apparently forgot. Another possible variation is that for example instead of such a lever or handle or button for example the user opens the preferably small doors of the cable or socket compartment or compartments for example by turning the car key in the other direction for example beyond the psition where the key can be removed (i.e. for example to the left) before removing it, but this is less preferable since many users for example are used to turn the key back all the way in order to fully turn off the car and remove the key so this might be confusing and contrary to habits from driving normal cars. Another possible variation is that for example for one or a few minutes after the user comes out of the car or other reasonable period (for example after he/she has closed the car door and is outside, which can preferably be determined by the car computer for example by finding the distance between itself and the user's remote control, for example by exchanging automatic wireless pulses between them, or for example by weight sensors on the seats which can determine for example if there are passengers in the car or not) or for example for a few minutes or other reasonable period since the user opens the car door or doors preferably the car computer for example causes for example a preferably transparent or semitransparent frame that surrounds the preferably small door of the cable or socket compartments (and for example contains light bulbs or LEDs) for example to flash automatically with a light that can serve for example both for reminding the user to plug-in the car and/or to help him/her see the location of the preferably small door for example also in the dark).
Preferably for example the internal switch or lever in the car (or for example the car's remote control or other device that can open the door of the cable or socket compartment) preferably opens the preferably small door of the cable or socket compartment for example only partially so that for example the cable cannot fall out or start to come out by itself so that for example when the user comes out of the car preferably the he/she has to further open the car with his hand and for example pull 24/12/08 Yaron Mayer & Haim Gadassi 164/304 out the cable, or for example it is opened more fully but the user for example still has to press something for example on the outside to release the cable, and/or for example the cable is held inside anyway for example by a roller for example with a spring and/or electric motor so that the cable comes out for example only if the user pulls it, as explained also elsewhere in this applictaion, and preferably for example if a few minutes (or other reasonable period) has passed and the user still has not plugged-in the cable or at least pulled it out, preferably the car computer for example automatically closes the preferably small door again (for example with or without first trying to remind the user again for example through his/her remote control, as explained above). Another possible variation is that preferably the user can also open or close the preferably small door of the cable or socket compartment for example through a button on his/her remote control (preferably for example in addition to being able to open it for example through a button or handle or lever within the car as explained above), for example by a separate button which can for example open or close the doors of the cable or socket compartments or for example when locking the car with the remote for example the compartment door automatically opens (and preferably automatically closes again for example after a few minutes if the user has not pulled out the cable, or for example plugged in a cable from the recharge post if for example it is a socket) (however this has the disadvantage unlike the above variation of having to open the preferably small door of the cable or socket compartment from inside the car the car computer does not know this way before the user gets out of the car if he apparently forgot to plug in the cable). Another possible variation is that for example when the user for example locks or unlocks the car for example with the remote control, preferably instead of beeping the remote control for example says the words "opening car" or "closing car" or similar wording for example before acting or for example "car closed"
or for example "car open" for example afterwards (for example based on prerecorded messages) and/or for example says "cable door is now open" or for example "cable doors are now open" or for example similar wording, which can also serve for example to remind the user about plugging in the cable, and/or for example the user can click for example on a separate button on the remote control which for example closes all the cable or socket doors preferably immediately instead of waiting for automatic re-closing (preferably this can be for example the same button that can also be used for example for telling the car computer to instruct the recharge post for example through the data link or for example a separate button). (As explained elsewhere in this application the data link can also be for example communication of data on top of the power wires but more preferably it is a separate physical link, for example based on optic fibers or on one or more additional wires in the cable which are used for the data transfer). As explained elsewhere in this application, if the car has for example at least two or more recharge cables and/or sockets, preferably at least if there are for example just two preferably there is for example a separate switch or handle for each or for example the same handle can be used differently to choose which of them to open or for example the same switch or handle or for example the remote control preferably opens all of these small doors preferably, at the same time and for example after 1 minute or few minutes or other reasonable time as explained above preferably for example the car computer automatically closes again all the small doors from which a cable has not been pulled out or for example has not been plugged in (if it is a socket) which means that for example if 24/12/08 Yaron Mayer & Haim Gadassi 165/304 the computer senses that for example one of the small doors cannot be closed (for example due to the cable) preferably it stops trying to close the small door.
Preferably the user can for example disable such automatic reminders or can for example disable the in-advance reminder and leave only the reminder if the user's apparently forgot or for example vice versa - so that the user for example prefers a reminder in advance but no nudging afterwards if the user has not plugged the cable (and/or for example the default is that if for example the computer reminds the user in advance the reminder is not repeated afterwards for example if the user starts to walk away as explained above), or for example the computer can remind the user for example to plug the cable for example in advance even without identifying if there is a recharge post next to the parking place, for example by reminding the user to connect in a conditional manner (for example "Please remember to plug-in the recharge cable if there is a recharge post here" or similar meaning phrases), but this less preferable since it can be even more annoying for example if there is no recharge post there and thus the message is irrelevant. If for example when the user parks the car the computer also asks the user for example how long he/she intends to stay in the parking place or for example when he/she intends to return, preferably there is a certain default order of questions and/or reminders, so that for example the computer preferably first asks the user about his/her intensions (preferably only if the question is needed in this case, as explained elsewhere in this application) and preferably afterwards reminds him/her about plugging-in the cable (since for example the decision if to remind the user to plug-in the cable can also be change based on his/her reply about the timing - since if the user for example intends to come back in few minutes there is no point in plugging the car, and for example since it makes sense to remind the user about plugging-in later since it's typically the last thing or one of the last things that the user has to do after exiting the car).
Preferably the user can also change these default orders if desired for example through a menu which for example shows each type of possible questions and/or reminders - for example in general or for example based on categories (such as for example questions and/or reminders when parking, questions and/or reminders when starting to drive, questions and/or reminders during driving, etc), so that for example the user can enable or disable questions and/or reminders, and/or for example change their order within the same category if relevant, and/or for example change the timing and/or various conditions related to the question or reminder (so that for example if the users leaves the reminder to plug-in the cable enabled, preferably the user can also choose for example if the reminder will be sounded for example after putting the gear or drive control in the parking position or after turning off the engine or turning off the car key partially (for example pert of the way) or for example fully, or for example location and/or time based - for example remind the user only when coming home in the evening but not when parking at work or in the morning, or for example remind the user at work or in the morning only if the user actually forgot to plug-in the cable but remind the user at home in the evening both in advance and for example again in case the user actually forgot, since plugging in at night is the most important time, and/or other rules).
Since at least in some of these variations the car computer can for example remind the user to plug-in the cable for example even after the user has left the car as explained above or can for example send/him her other automatic messages and/or for example respond to various queries or receive for example regular updates for 24/12/08 Yaron Mayer & Haim Gadassi 166/304 example from the service provider's main computers, as explained elsewhere in this application, or for example display various important messages while the user is in the car but the user might for example turn off the car key for example as soon as he/she put the gear or drive control in parking, this means that preferably at least some types of messages (such as for example the reminder to plug-in the cable and/or for example alerts for example about problems in the cable of in the connection even though the user usually remains out of the car after plugging-in the cable, as explained elsewhere in this application) or for example as a general rule, preferably the car computer remains active or preferably at least for example in stand-by or other energy saving mode preferably even after the user turns off the car and preferably even after the user locks the car and walks away, and/or can for example turn itself off or into standby mode but can preferably be awakened automatically for example by events received for example through the cellular communication or for example generated by the recharger. Preferably the car computer for example automatically avoids reminding the user about plugging-in the cable for example if the user goes to a place in which the user (based on his/her previous patterns) for example typically stays only a few minutes or for example less than 20 or 30 minutes or other threshold period, such as for example when going to the supermarket or for example grocery store - even if the car is for example parking near a recharge post. (Another possible variation is that for example the car computer also learns automatically for example the user's typical sequence or order of actions for example when parking and preparing to plug-in the cable, so that for example if the user does not do the usual things the computer can for example increase the likelihood of the estimate that the user is probably not going to plug-in the cable and for example needs a reminder, but that can be less reliable and/or can be more annoying and is less preferable). (Another possible variation is that preferably for example cellular phones can also for example remind the user automatically to recharge the phone for example by synthesized speech or pre-recorded messages, for example when the battery energy is below a certain level and/or for example when the phone senses that the user has come home (for example based on cellular triangulation) and/or for example at a certain hour in the evening, and/or for example if the phone senses that the recharger is nearby for example by automatic short range bluetooth or UWB communication between the phone and the recharger - such as for example 10 meters or less or other similar short range wireless communication or for example similar infrared communication, preferably with the same chip that the phone should have anyway for communication with such wireless headsets - which means preferably only having to add the appropriate abilities also to the recharger and some addition to the firmware). Preferably the sensing that the user has started to walk away can be done for example by automatic wireless communication for example with the user's smart card if a smart card which has also wireless communication is used with the recharge post, and/or for example if the user has some RFID device for this, and/or for example through automatic short wireless communication with the user's cellphone, for example through Bluetooth or UWB, and/or for example through wireless communication with the user's remote lock so that the car can also send wireless messages to the remote and not only receive them from the remote.
Another possible variation is that preferably similar warnings and/or reminders can be issued automatically for example by the car computer or for example by the 24/12/08 Yaron Mayer & Haim Gadassi 167/304 remote control for example also if for example a certain time (such as for example 10-30 seconds or more or a minute or more or other reasonable time) has passed for example from the time the user exited the car and the user has not yet locked the car for example with the remote control and/or for example the user for example started to walk way for example more than a certain distance (i.e. for example the car computer or the remote control can warn the user or remind him/her to lock the car), and preferably this warning can be issued for example without checking if there are still passengers in the car but more preferably this is combined for example with automatic sensing by the car computer for example if there are still passengers in the car - for example by weight sensors on the seats and/or for example C02 sensors and/or for example volume sensors which can sense movement in the car and/or for example internal video camera or for example other optical sensors which can for example sense the shape or height of objects that are above the seats, so that preferably the computer issues the warning preferably only if it senses that there are no passenger left in the car, and preferably if the computer is not sure if there are still passengers in the car then preferably the car computer issues the warning anyway if the user has not yet locked the car as explained above. Another possible variation is that for example when the car receives the signal to lock itself or to open itself preferably it also sends an automatic acknowledgement back to the remote control and/or for example when the user plugs-in the cable (or for example when removing it) preferably the car computer for example sends an acknowledgement about this to the remote control and preferably the remote control remembers the last states so that for example the user can check again for example a few minutes later for example also through the state indicated on the remote for example if he/she is sure for example if according to the remote he/she indeed locked the car and/or if he/she for example plugged the cable.

In addition, preferably after the user has plugged in the car, since typically the recharge will usually not actually start at the same time but wait for a command from the main computers of the service provider and/or of the electric company, as explained elsewhere in this application, preferably the user gets an automatic indication which indicates for example that the car has been properly identified and/or authorized for recharge and/or for example that the connection has been made properly - for example by auditory cue (which can be for example a certain tone and/or synthesized speech) and/or for example by visual indicator (such as for example some green or other light on the recharge post and/or for example by an appropriate textual message displayed for example on a display screen for example on the recharge post and/or on the display of the car's computer). Another possible variation is that preferably similarly the car computer can also for example alert the user in a similar way for example if the user has parked the car and starts to walk away for example beyond a certain distance for example without locking the doors or windows and/or for example after a certain time - at least for example if the computer senses for example based on seat-weight and/or internal visual detectors that no additional person is still in the car, and/or for example also the opposite - if the user has locked the doors and windows for example by remote but the car senses that there is still someone (for example a baby or child or dog) on one of the seats, however this is preferably based for example also on smart automatic analysis of automatic internal video images that can detect for example movement or the shape 24/12/08 Yaron Mayer & Haim Gadassi 168/304 of humans or animals, and/or for example based on volume detectors which detect for example movement for example in the same way that this is used for alarms, and/or for example by internal C02 detectors on the inside of the car that can for example detect increase in C02 levels inside the car after the user has left the car.
Another possible variation is that the car computer can for example similarly warn the user for example if he/she has left for example some other electric systems on and parked and walked away, such as for example the radio, for example when no other user is sensed in the car. Of course, like in other variations in this application, various combinations of the above variations and/or other variations can also be used.

Another possible variation is that if there is for example at least in the beginning for example a recharge post only in one of each few parking places, preferably there are for example sideways belts or for example small rollers which can for example be used to move the car for example to the next nearby parking spot if it is free, so that for example if a car near a recharge post has finished recharging and its connection with the recharge post has been preferably automatically removed, when a new user arrives he/she can for example press a button which causes the car to be moved to the near free parking place, or for example the system can sense that the neighboring parking spot is empty and move the car there automatically.
Another possible variation is that for example at least some parking places which are near a recharge post have for example a physical lock (such as for example pronged poles or for example one or more horizontal or vertical poles which can be for example automatically moved for example up or down), which preferably opens only for example when an electric car connects to the recharge post or for example when its computer sends the recharge post (or for example directly to the service provider's main computers) a special wireless code (for example through Wimax or Bluetooth or UWB) which preferably only electric cars can send (or for example sends it wirelessly the car's unique ID, preferably in an encrypted way which preferably changes each time) or for example when the user inserts or for example passes his/her smart card through the recharge post, so that for example a non-electric car cannot physically enter that parking place, and/or for example at least some such parking places are marked as allowed only for electric cars so that if for example a normal car is parked in them the driver can be fined for example by city traffic inspectors.

As explained above also in the patent summary, the communication between the rechargers or recharge posts and the central computers of the service provider (and/or for example of the electric company) is preferably for example through transferring data through the electricity lines or for example through a cellular network or for example wimax or similar network (which preferably acts for example as a bridge to the Internet) or for example other connection preferably through the Internet or similar network, and/or preferably at least nearby rechargers or recharge posts can also similarly communicate directly between themselves.
This means that the recharger or recharge post preferably contains for example a wireless and/or cellular communications chip or card or unit, which can preferably connect for example through the cellular network and/or through The Internet. Another possible variation is that for example at least in some places the rechargers or 24/12/08 Yaron Mayer & Haim Gadassi 169/304 recharge posts are preferably connected for example to the Internet for example through for example ADSL or Coax cable or other electric cable or for example optic fiber which for example connects them to a nearby street switchboard (for example by adding them to existing phone company street switchboards - for example the same ones which connect to houses for example through ADSL and for example connect to the phone company's server through optic fibers) or for example adding special street switchboards for example very few hundred meters or for example in one or more places in the parking lot, so that preferably multiple nearby rechargers or recharge posts are physically connected through the same switchboard preferably through underground cable or optic fiber or for example communicate with it wirelessly. However, the car's computer wireless communication with the system is preferably limited to sending minimum digital data communications (or for example it preferably receives much more information than it sends), and it preferably uses an external antenna, which can be for example the same cellular antenna that can be used by the cellular speaker in the car or a separate antenna, but preferably the antenna (or antennas) is installed preferably as far way as possible from the driver and the passengers or for example at least away from their heads, for example at the front edge or back edge of the car (for example at or near the position of the exhaust pipe of normal cars is located), so that the users are not exposed to unnecessary radiation. Preferably this is done also for example with normal for example gasoline cars, for example by putting the cellular antenna for example at the back end of the car for example at the other side of where the exhaust tail pipe is so that preferably there is for example a distance of at least half a meter or one meter or other reasonable distance between the cellular antenna and the exhaust pipe in such cars. But in electric cars in which the car computer for example communicates regularly for example through cellular or cellular Internet or for example wi-fi or wi-max or other wireless communication for example with the service provider's main computer this is even more important since otherwise the users might be exposed automatically to more cellular radiation than for example in normal cars.
Another possible variation is that for example the same internal cellular wireless communication unit which the car computer uses for example to communicate for example through cellular Internet and/or for example through the SMS system with the service provider's main computers can also be used for example as a car phone for the user - preferably for example through time sharing with the SMS system at the same time or for example through VOIP through the same cellular Internet connection. Another possible variation is that if the car for example uses a cellular speaker system in which for example one cellular phone is constantly on the speaker in the car and the user has a separate cellular phone which he/she takes with him and for example the user has to remember to disable the phone that is in the car when leaving the car since it is the same number (as is done for example sometimes by the Pelephon company in Israel), preferably this is improved so that for example the two phones that share the same number can also communicate with each other for example through VOIP and/or for example they can both ring at the same time or both be used without disabling the other, so that for example whichever phone the user opens first becomes for example temporarily the active phone until the user closes it and opens the other phone, and/or for example if the user forgets to disable the phone that is in the car while leaving the car preferably for example the phone that he/is taking with him for example reminds him/her automatically for example 24/12/08 Yaron Mayer & Haim Gadassi 170/304 through visual and/or auditory alert to do it (for example by sensing the phone is now a certain distance or more away from the other phone), and/or for example the user can also transfer the control to the phone that he/she carries with him/her through that phone and then preferably the cellular system automatically sends the appropriate control command to the other phone.

In addition, preferably the recharger or recharge post has for example internal sensors that can automatically diagnose for example various problems including for example if one or more elements in it starts to act erratically or is malfunctioning or for example if one of its cables has become damaged or exposed and can preferably automatically report this to the main computers and/or even for example at least in some cases automatically lock itself off and preferably for example automatically display a malfunction warning or sign, and/or for example depending on the problem and/or for example if it stops communication with the main computers for example for longer than a certain time period, preferably technicians are alerted automatically to its condition and location, which is preferably automatically identified based on its ID. In addition, preferably even if a cable becomes for example broken or exposed preferably there is no danger of getting electrified because the recharger or recharge post won't send any high voltage or current through it unless it has been verified as connected properly to a car, and preferably even if it is connected and currently recharging and for example the cable's isolation is wounded and someone for example bumps into it, the recharger or recharge post preferably automatically stops the current immediately for example by sensing the change in the cable's condition preferably as soon as it happens or for example if it senses unexpected grounding.

While the invention has been described with respect to a limited number of embodiments, it will be appreciated that many variations, modifications, expansions and other applications of the invention may be made which are included within the scope of the present invention, as would be obvious to those skilled in the art.

140. The system of any of the above claims wherein at least one of the following features exists:
a. There is an additional coil or coils in the electric engine added to or inherently built in the rotor so that the engine can be used as an efficient transformer for V2G even without actually rotating the engine, by temporarily disconnecting the engine's electrical power unit from the typical 3 coils that are normally used in the stator when driving the car and powering instead the coil or coils of the rotor, so that the correct voltage and frequency is drawn from the stator coils with the desired parameters needed by the electric company, and/or a similar configuration can be used also during recharging the car's battery or batteries so that the 3 phases of the stator are connected to AC input from the network but in a way that does not cause the engine's rotor to turn, and the current for the recharging is then drawn out of the coil or coils of the rotor, and thus less diodes are needed for the diode bridge that rectifies the AC current and turns it into DC;

b. The recharge posts can automatically route sets of cars when in V2G mode in a way that uses their step-down units so that one or two or more car batteries are used serially in one direction and one or two or more car batteries are used in the opposite direction, so that synchronized change in their step-down units creates the desired AC voltage and cycles, and/or if the car includes internal battery elements which can be routed more serially for higher voltage during recharge this can also be similarly used as desired while drawing back energy to the grid in V2G mode;
c. At least in some places within the same area or parking lot there are also at least some DC line connections between at least some recharge posts so that they can also transfer energy directly in DC more from vehicle to vehicle or to other nearby local devices, and this is done by automatic serial rerouting of at least some of the connections between groups of recharge posts and/or fast multiplexing of the lines so that multiple DC inputs can behave in desired aggregations of voltage and/or amperage;
d. When users temporarily freeze their subscription for a few weeks or other period due to traveling out of the country or other reasons, during this period they are requested by the service provider to leave their car connected to a recharge post so that the service provider can utilize their car's battery or batteries for V2G services if needed also to a substantially larger extent than batteries in cars that are being used, since until the user returns the service provider can enable even considerably deeper draining of the battery as needed;
e. The user can see on the car's computer and/or on the service provider's web site and/or on the electric company's web site and/or on monthly bills or reports from the electric company or from the service provider an automatic summary of how much revenue or credit points or monthly bills or over other periods the user has received based on V2G services.

b. The recharge posts can automatically route sets of cars when in V2G mode in a way that uses their step-down units so that one or two or more car batteries are used serially in one direction and one or two or more car batteries are used in the opposite direction, so that synchronized change in their step-down units creates the desired AC voltage and cycles, and/or if the car includes internal battery elements which can be routed more serially for higher voltage during recharge this can also be similarly used as desired while drawing back energy to the grid in V2G mode;
c. At least in some places within the same area or parking lot there are also at least some DC line connections between at least some recharge posts so that they can also transfer energy directly in DC more from vehicle to vehicle or to other nearby local devices, and this is done by automatic serial rerouting of at least some of the connections between groups of recharge posts and/or fast multiplexing of the lines so that multiple DC inputs can behave in desired aggregations of voltage and/or amperage;

d. When users temporarily freeze their subscription for a few weeks or other period due to traveling out of the country or other reasons, during this period they are requested by the service provider to leave their car connected to a recharge post so that the service provider can utilize their car's battery or batteries for V2G services if needed also to a substantially larger extent than batteries in cars that are being used, since until the user returns the service provider can enable even considerably deeper draining of the battery as needed;

182. The method of any of the above claims wherein at least one of the following features exists:

a. When the user parks the car - after the user has finished moving the gear or drive controller into the parking position, or after the user also turns off the engine and/or turns off the car key and/or removes the car and/or when the user starts to open the car door, the car computer can automatically remind the user to plug-in the cable;
b. If the user has to open the outside door of the cable or socket compartment by pushing a button or handle or lever within the car, if the user did not push the relevant button or handle and starts to open the car door the car computer can automatically remind the user to plug-in the cable;
c. For one or a few minutes after the user comes out of the car or other reasonable period or for a few minutes since the user opens the car door or doors or other reasonable period, the car computer causes a frame that surrounds the door of the cable or socket compartments to flash automatically with a light that can serve both for reminding the user to plug-in the car and/or to help him/her see the location of said door also in the dark;
d. After the door of the cable or socket compartment of the car has been opened, if a few minutes or other reasonable period has passed and the user still has not plugged-in the cable or pulled it out, car computer automatically closes the small door again;
e. The user can also open or close the small door of the cable or socket compartment also through a button on his/her remote control, by a separate button which can open or close the doors of the cable or socket compartments, or when locking the car with the remote the compartment door automatically opens;
f. When the user locks or unlocks the car with the remote control, instead of beeping the remote control says the words "opening car" or "closing car" or similar wording before acting or "car closed" or "car open" afterwards and/or says "cable door is now open" or "cable doors are now open" or similar wording, which can also serve to remind the user about plugging in the cable, and/or the user can click on a separate button on the remote control which closes all the cable or socket doors instead of waiting for automatic re-closing;
g. The user can disable the automatic reminder to plug-in the cable or can disable the in-advance reminder and leave only the reminder if the user's apparently forgot, or vice versa;
h. If when the user parks the car the computer also asks the user how long he/she intends to stay in the parking place or when he/she intends to return, the computer first asks the user about his/her intensions and afterwards reminds him/her about plugging-in the cable;
i. The user can change the default order of questions and/or reminders;
j. The user can change the default order of questions and/or reminders, through a menu which shows each type of possible questions and/or reminders in general or based on categories, so that the user can enable or disable questions and/or reminders, and/or change their order within the same category if relevant, and/or change the timing and/or various conditions related to the question or reminder;

k. The car computer remains active or at least in stand-by or other energy saving mode even after the user turns off the car and even after the user locks the car and walks away;
1. The car computer can turn itself off or into standby mode but can be awakened automatically by events received through the cellular communication or generated by the recharger;
m. The car computer automatically avoids reminding the user about plugging-in the cable if the user goes to a place in which the user based on his/her previous patterns typically stays only a few minutes or less than 20 or 30 minutes or other threshold period.

183. The method of any of the above claims wherein at least one of the following features exists:
a. The car computer or the remote control can warn the user or remind him/her to lock the car if a certain time has passed from the time the user exited the car and the user has not yet locked the car and/or the user started to walk way more than a certain distance, and this warning can be issued without checking if there are still passengers in the car, or is combined with automatic sensing by the car computer if there are still passengers in the car so that the computer issues the warning only if it senses that there are no passenger left in the car;
b. When the car receives the signal to lock itself or to open itself it also sends an automatic acknowledgement back to the remote control, and/or when the user plugs-in the cable or when removing it the car computer sends an acknowledgement about this to the remote control, and the remote control remembers the last states so that the user can check again later also through the state indicated on the remote if he/she indeed locked the car and/or plugged the cable;
c. The cellular antenna is installed at the front edge or back edge of the car or at or near the position of the exhaust pipe of normal cars is located, so that it is moved away from the heads of people in the car;
d. The car computer automatically keeps logs of the number of turns or sharp turns which the user made with the car within the last minute and/or the last few minutes of driving and/or other reasonable time period together with a speeds log for the same period or periods and can automatically warn the user if the user is driving too fast for the number and/or sharpness of the, and/or the computer can also warn the user similarly about other dangerous driving patterns and/or behaviors;
e. The recharge cable is rolled inside the car or inside the recharge post on a roller or reel or wheel which is controlled by an electric motor together with sensors that can sense the amount of pull on the cable, so that when there is a pull on the reel or wheel or roller the motor can release the reel or wheel at a speed that matches the amount of the pull so as to keep the resistance constant or with gradually increasing resistance, and/or the reel or wheel itself has a sufficient amount of friction to release the cable gradually;
f. After the cable is plugged-in the computer takes into account the cable's weight and/or the known height of the cable compartment's door and of the socket and/or other known parameters and pulls the cable back automatically with sufficient force so that there is sufficient slack in the cable but the cable is sufficiently above ground;
g. If the cable is spiral but with a relatively small diameter of the spiral the cable is rolled on a reel or roller or wheel inside the car or inside the recharge post.
