Description

Description [0001] This invention relates to a system which allows an owner or user of an electric vehicle or electric powered vehicle, in particular a so-called pedelec electric bicycle or e-bike, to cover greater distances in any parts of the country within The range of its battery capacity can always replace its partially or completely depleted battery with a built-in or matching fully charged battery. Thus, the users of such vehicles can also be relieved of the concern about the state of charge, and they are not limited by local and temporal restrictions associated with the charging of their batteries.

Electric bikes are enjoying increasing popularity and today belong to the general street scene. While their battery capacity is sufficient for shorter journeys, as long as the battery can be fully recharged in the evening and overnight, the user of an electric vehicle, and in particular the user of an electric bicycle, soon reaches the capacity limits of the battery when traveling a long distance want. Often the range is about 30km, with more advanced batteries, it will soon be bigger. Cyclists in particular would like to go on longer tours with electric bicycles and, in particular, tours lasting several days and not be bound to specific routes. The drivers do not want to constantly have to deal with the question of where to land their batteries again. So far, they can only manage to take a second or even third charged battery for replacement and use it on the move as soon as the battery in use is empty. An additional battery to be carried increases the loading of the bike by a few kilograms and is not very desirable. In addition, the batteries have to be recharged over the next night on the mains, for which then two or even three chargers would have to be carried, and finally, these batteries are quite expensive.

If all batteries were identical, the construction of a network of change stations would not be so complicated. The fact remains that there are a variety of battery patterns, and these are not compatible with each other. A specific battery only fits into specific battery compartments on the bike.

In addition, there is a problem to be solved also to find somewhere on the way the next charging or changing station, if there were such at all nationwide. But not only that, you also need to know where and how many batteries of the type you are looking for, and then only when charged. After all, a charged battery will cost something in exchange for an empty one, so a billing system should be included that is accessible to everyone, and finally, a change station should be as automated as possible and work around the clock, so without staff and therefore economically optimized. It's all a challenge. Another goal to be achieved with these change stations is to be able to offer the charges cheaper than what would cost a public transport ticket for the same route, or in the case of electrically powered mountain bikes, which would cost the ticket of a mountain railway.

For these reasons, it is the object of the present invention to provide a system for building and operating a nationwide network of battery changing stations for electric vehicles, so that with an electric vehicle or an electric bike route independent within its range, a changeover station can be reached at which the appropriate battery is available in a charged state, and this battery is there exchangeable for a fee, in exchange with the dead battery. This network should allow you to plan and de-route routes criss-cross in a certain region or part of the country or in a whole country, and always have enough change stations, so you never get left behind with a dead battery. So you have to know for this purpose, which type of battery is available in which amount in a charged state and at what time, at any time, and you must be able to reserve the battery binding and communicate with the exchange station.

This object is achieved by a system for building and operating a nationwide network of battery changing stations for electric vehicles with removable battery of all kinds, and especially electric bicycles, consisting of a variety of exchange stations, with a single exchange station includes a locker shelf , with a number of lockers for inserting different types of batteries in associated locks in the lockers, each locker has a power connector with charging unit for the battery type in question and a measuring device for measuring the state of charge of a battery used, and that the changing station via a computer (Central Processing Unit CPU) with connection to the measuring devices and a wireless interface for communication with mobile phones with appropriate app, so that the system and all its switching stations via mobile phone app with the mobile phones and where the change stations can be used with the following functions: 1. identification of the user or requester, 2. indication of the currently available battery types and their number, as well as their state of charge; 3. Time when its full charge has been reached or reached; 4. Reserving one or more batteries during a time slot against a reservation fee; 5. Coded automatic opening and closing of a specific locker to replace the empty or partially charged battery with a fully charged battery of associated secured locks by an identified and authorized user, 6. Billing for related battery capacity by debiting a user account.

Based on the figures, a system with changing stations is shown, as well as various exchange stations and battery types, and the system and its function and management is described in detail below: It shows:

There are currently a variety of e-bike batteries, but no standard, no uniform battery, not even uniform chargers, to which all battery types would be loadable. The chargers have conventional power plugs and are the same for almost all chargers. While there are e-bike charging stations, there are no pre-charged batteries available on-site that can be reserved by mobile phone for pick-up. In Switzerland, for example, there is the Herzroute (www.herzroute.ch), along which there are preferably inns in which batteries are charged to a certain type of rental bicycle, and when a group of cyclists arrive, the batteries of their bicycles are changed and the bicycles can be recharged with charged batteries, so that the whole route from Lake Constance to Lake Geneva and vice versa, that is, can be traveled throughout Switzerland. There are a number of other routes within Switzerland that are organized in the same way.

There are also isolated and electronically lockable lockers for other purposes, but without socket with power connection for charging a bicycle battery, and without heating, while temperatures of 20-25 ° C would be ideal when loading, and no way, the charging status to measure and display a battery. The charging status is a mathematical calculation of the associated software app of the present appendix. For example, a battery type xy needs 5 hours to charge. The time from connection to the charger plus 5 hours gives the time when the battery is fully charged again. And there are also electronic lockers, but they work with a central reader head (reader / scanner) for QR, barcode, RFID, etc. Furthermore, electronic lockers with HEID push button are known, but not with changeable match frequencies on the locker locks.

Page, but only in a chip of the user, for example, integrated in a bracelet or in a card with credit card format. Finally, reservation system applications are known, but none to be able to send a new frequency indication to selected RFID readers that correspond to, for example, the RFID adhesive transmit signal on the user's battery. So all sorts of technical components are available, but never before have they been coupled in an intelligent way so that the desired service can be realized, namely that a driver of an electric bike can check at any time where charged batteries are available in large numbers or be available in a charged state until a certain selectable time. And the cyclist can not reserve without the help of local helpers only by phone one or more such charged batteries at a changing station under payment, and then even at a uniform exchange rate or the related charge capacity, the battery actually there for a fee. For many payments, cards, codes, keys, coins, etc. are still being used rather than an electronic billing system accepting prepayments, or after use e.g. allows immediate debits or generates monthly statements.

The system presented here should offer just that. The concept is described here below with reference to FIG. 1, in which a system of a plurality of changing stations is shown, as well as a user 12 and his mobile telephone 9. The changing stations are here symbolized by rectangles, each changing station having a plurality of lockers, in which batteries of different types are charged. Such exchanges are set up over a whole territory distributed so that each road section within this territory passes within a range of, for example, 30 km at a change station. Depending on the chosen route, a cyclist will pass one or more of these switch stations as shown, where he can exchange the bicycle battery and continue driving with a fully charged battery. In the example shown, his route leads over fictional towns with changing stations. His mobile phone has an app belonging to the system, by means of which the system is manageable. Among other things, the app allows at least the following functions to be performed: 1. Identification of the user or requester by the system, 2. Indication of the battery types currently available in a selectable changing station and their number, as well as their state of charge. (The user data of each user are stored in the system of the system, ie his e-bike and the corresponding battery type are known to the system.) An e-biker can also have stored several e-bikes or battery types, which he can then select as needed Depending on your choice, you will only see the type of battery you are currently using and the availability of this specific type of battery.) 3. Time when the full charge of the desired battery has been reached or reached. 4. Reserve one or more batteries during a time window, optionally against a reservation fee. Alternatively, the system can only work with a change fee - no reservation fee. A reservation is then canceled by the system if the e-biker does not change the battery within a certain time window. 5. Coded automatic opening and closing of a particular safe deposit box of a particular exchange station for replacement of the empty or partially charged battery with a fully charged battery by an identified and authorized user; 6. Billing per battery change or battery purchased by debiting a user account.

Based on the separately shown in Fig. 1 mobile phone display 10 recognizes the representation of a possible image, which can display the app, among other things. The display 10 here displays the change stations on a map, and with the cyclist, the location of the user 12 is displayed, which is achieved via the GPS function of the mobile phone 9. It confirms a reservation of a battery in a specific selected changeover station, as well as whether the reservation has been successfully completed and possibly paid for depending on the system design. The app continuously calculates the driving distances to the various reachable change stations and in particular to those on the selected route. Before commencing a journey, the user 12 plans a route and, based on the distance information, he recognizes at which exchange stations the exchange of his battery with a fully charged battery is indicated. Accordingly, he reserves these battery types in the selected change stations of his route. For this he enters his battery type and his change window from to and instantly recognizes in which changing station fully charged batteries of that type are available for these timeslots. He can reserve a fully charged battery for replacement within a specific time window - preferably free of charge. In another interpretation of the system, it may also be that depending on the size of the time window and the length of time to the effective collection of the battery a reservation fee will be charged directly to his account, if he confirms this reservation. In any case, a charge to his account after a battery change takes place. The system or its software will detect if the reservation is not possible, such as when no charged battery is available in the desired period, because all are already reserved by other users or no battery of this type is available. As mentioned, reservations can be made for free or for a fee - depending on the wishes of the operator of the facility. If a user represents several people in a group, he can register their bicycles for all group members and deposit the battery types and load the app onto the mobile device. So he can also reserve several batteries when he organizes a trip as a leader of a group of cyclists. It is clear that the app can include other pages and functions that are available with the touch screen function, such as displaying the account balance, specific requests to each selectable change station, etc. The computer (CPU) of each exchange station via the Internet Access the account of each user and, after successful battery change by the user, make a debit from his bank account, Postfinance or credit card account and deduct penalty charges directly from the designated account of the user. Above all, it is possible to provide a monthly billing, with prepayments being credited to the user account. Such prepayments also help to systematically push the system through large membership and help the system make a breakthrough.

If the user within the reserved time window at the exchange station, where he has reserved the battery, the empty locker detects the RFID of the incoming empty battery and opens automatically, or the locker can be by means of Near Filed Communication NFC with the Open the user's mobile phone. Alternatively, the system may be designed so that the user can open the locker door and remove the charged battery by sending a code to a particular locker number provided by the app. The user inserts this discharged battery into this open locker and connects it to the charging station. Through the charge control in the locker, the system detects whether the battery is being actively charged and only then allows the door to lock. Alternatively, the system may be designed so that first the discharged battery is placed in an empty locker and connected to the charging station, and that only when the start of charging to the empty battery is confirmed, the door of another locker with the fully charged battery opens. As soon as the e-biker (user) has removed the fully charged battery, the door will close automatically if the e-biker did not close the door properly. In order to always use a discharged battery of the same type in exchange with a charged one, various measures can help. For example, the system may be designed so that a charged battery can only be removed if a discharged battery has been successfully connected for charging, otherwise a lock will not release the charged battery. The discharged battery is then latched into the separate lock, which opens again only when another battery has been connected in the other lock. In addition, the user account may be charged a penalty fee if the user leaves the locker door open for more than a certain amount of time. Once the user has supplied the discharged battery in the locker and the door has been successfully closed and the fully charged battery has been removed from the safe, this is confirmed via app and otherwise the system alerts the user within a certain time and indicates a possible penalty. For each change, the user account will be charged a change fee. This charge is stored in the system for the battery type. The exchange price is determined by all relevant costs for the system, eg. B. Battery costs (battery divided by the specified possible number of charges), locker costs (number lockers, number of battery charging options over 5 years), operating costs (electricity, app and software development costs) over 5 years divided by the number of planned changes, possibly personnel costs for the Maintenance, effort for "Trouble-Shooting", software error messages, battery replacement, transport costs etc. A change price of the order of CHF 5.- for batteries with standard performance is aimed for. A user therefore needs nothing more than a mobile phone as well as the specific app for managing the system with his conventional electric bicycle. From now on it has an almost endless range within the territory in which the plant is built and which is therefore provided with a desired sufficient density of change stations.

Fig. 2 shows a possible locker shelf 1 with lockable and openable by entering codes lockers 2 with their electrically operated locks 4 openable doors 3. Such shelves 1 can be placed outside or in a building. When installed outdoors, they are equipped with roofs and heating, so they are weatherproof and suitable for winter use. The shelf shown here can hold 36 batteries, 10 such shelves therefore 360 batteries.

3 shows a single locker 2 of this shelf 1 with open door 3. Each such door 3 can be equipped with a reading head (reader / scanner) 15 for QR, barcodes or RFIDs, as well as with a HEID push button sixteenth In addition, a battery 5, her charger 6 and a power cord 7 is shown. Inside the compartment 2 can be seen the power connector 8. There, a charger 6 is plugged, to which the battery to be charged 5 is docked. The battery 5 can be secured for this purpose with a lock, not shown, which opens only when another battery is successfully connected to a second lock for loading the charging station, and the door 3 can only be successfully closed when the battery to be charged in turn secured in this castle. It can also be a reading head (reader / scanner) for QR, barcodes or RFIDs installed on the shelf 1, and a HEID push button 16 on each door to open the relevant locker 2. Each locker 2 of the system is in addition to the socket 8 in addition to a charger and a meter for detecting the state of charge of the connected battery 5 and with electrical connections to a belonging to the shelf 1 computer (CPU) (intelligent chip) equipped, all doors and transmitters (RFID) centrally controls on the shelf and in which all systemically relevant Signals are processed and which has an interface to the mobile phones 9 all users.

Fig. 4 shows two larger, covered safe shelves 1, which are housed inside a building and are therefore particularly safe and independent of the weather, and in Fig. 5, a locker system with shelves 1 is shown, the

Lockers have 2 different sizes, to accommodate differently sized designed battery types, because there are a large variety of different batteries, with different shape and size and charging capacity. When changing it is important to pay attention to the order, as well as only charge batteries with 85% or less charge level. The system is also suitable as a sales platform for the handling of any products, such. B. for Alibaba products etc.

Fig. 6 shows, for example, a specific type of battery, as well as in front of a bicycle frame to be installed receptacle 11 which is mounted on the bicycle and from which the battery 5 can be removed. Fig. 7 shows another specific type of battery 5, and next to the associated charger 6 and power cord. 7

Fig. 8 shows another specific type of battery 5, here in the form of a box-shaped battery with their terminal poles. For this as well as for the range shown in Fig. 9 different sized batteries 5 of a certain type terminals are required with which the charger is connected in the locker to the poles.

Fig. 10 shows again another specific type of battery, and in addition the associated charger 6 and power cord 7, as well as Figs. 11 to 15. FIG. 15 shows a triangular battery, only to show how vielgestaltig the different batteries 5 are in the market. There are a variety of shapes, sizes, mounting systems on the bike, as well as different charging systems or chargers 6. Therefore, specific lockers 2 are needed on the shelf for specific batteries 5, so that everything fits together, which must fit. But most batteries 5 will fit in lockers 2 of size B 30 cm χ H 40 cm χ D 50 cm. Certain fixed-mounted and not easily replaceable vehicle batteries are not part of this battery exchange system.

Below, further explanations for the management of the system are disclosed. Based on the current drain in the lockers 2 and the corresponding detection by the computer (CPU) can be determined whether a battery 5 is properly connected in the locker 2 with the charger therein and is charged, and only then can the locker close and lock , The locker lock 4 can therefore only be completed when the system has recognized that the charging cycle of a battery 5 deposited in the locker 2 has begun.

The size of the lockers is matched to the average size of the batteries and their corresponding charger, for example, as mentioned B 30 cm χ H 40 cm χ D 50 cm. Each battery in the system is equipped with a passive RFID transmitter, which can be glued on, for example. Each locker can also have an active RFID reader, which can detect via a central GPS communicator, if a corresponding battery in sufficient proximity of the safe deposit box appears. Then the safe is automatically opened. As mentioned, the installation includes a communication app on the mobile phones 9 of the user 12, so that the users 12 can orient themselves via a reservation function and further information functions about the current state of the installation and the offer. In addition, their mobile phone 9 is connected to the GPS, so that the system knows where the individual users 12 are when they have activated the app and communicate with the system. The app also makes it possible to carry out any online system updates, such as integrating and displaying new replacement stations or new batteries, changes and shifts in battery types per locker, and opening communication with them and their use.

When a user 12 arrives at the change station to which he reserved a battery, the change station will recognize his battery via RFID reader or his mobile phone via, for example, Near Field Communication NFC or RFID reader and open a locker in which the matching battery charger is located. The locker, where the battery is fully charged, opens once the empty or partially charged battery is properly connected and, with the use of two lockers, one for the new one to be recharged and one for the fully charged battery charging battery was closed again. Thus, the e-biker can connect his empty battery to the charging station in the locker and then remove the fully charged battery and close the locker afterwards and lock. This, however, is only possible for him when the system has previously confirmed that the charging process started with the empty or partially discharged battery.

The application controls the choices on the basis of the data stored in the system: Each user and e-Bikerverfügt one of the system known user name and password. The system knows his e-bike, which he has announced via the app of the system, and the system thus knows the associated battery types, and other favorites for the selection process, the battery charging time per battery, the locker numbers, in which the corresponding batteries and via the app, all locations of the change stations belonging to the installation can be displayed on a map.

Further data is collected and stored when a battery is changed. Thus, it is recorded which e-bikers at which battery changeover station how many batteries of which type for which time reserved for pickup, which locker numbers contain these batteries, and when changing exactly when this change took place, from when the newly set battery is fully charged again , and the batteries, which are displayed in the network as fully charged, are visible to all users. Such calculations are based on stored master data. Information is sent via program to location apps, e.g. LEMnet sent, so that a route planning is possible. In more remote areas, the choice of battery types is smaller, which is why this information is significant. Of the

Claims (7)

Users should be able to see immediately if and when which battery will be available. Accordingly, he can put together his route and reserve the necessary batteries for himself via the app, whereby the principle first comes first served applies, however, a reservation fee is raised and punishment fees a misuse is prevented. The longer a battery is reserved in advance, the higher the reservation fee will be. If a battery is not picked up within the selected time window, it will be released by the system and will be made available to other users. However, the user may extend a reservation made by, for example, an hour or two or more, if he realizes that he will not be able to arrive at the changeover station at the previously selected time. This system thus makes it possible that the e-bikers no longer manage their own batteries and use a single battery, but they only use the charges of a variety of batteries that are available to them. For this they do not need to own these batteries - they only need their electric charge, just as the pantographs do not have to have the power grid, but only have to have the rights to receive from the same electricity for a fee. Such equipment may be operated by a non-profit organization to ensure that old batteries are replaced wherever they are recognized by the system due to poor charging or reduced end-loading capacity. The club members can take over the coordination and the cleaning and maintenance of the individual change stations of the plant. Such activities may also be organized by employment offices or municipalities, which may otherwise give unemployed people a welcome job. The cost to operate such a system will decrease with increasing distribution of the associated exchange stations and their use. The proposed robust locker systems will be the first to be amortized, after which it will take years before maintenance or replacement is needed. For example, there is room for changing stations with associated lockers in the numerous empty spaces created by the digitization of the economy of former post offices and shops. The currently large number of different battery types makes it impossible to use existing equipment. If an e-bike is changed, all batteries, charger plugs etc. must be changed. The e-biker pays the bill so far, but he can not go anywhere with a different battery. Only when he can change the battery at any time within his radius of action, as suggested here, thanks to such a system, does he become autonomous, so to speak. The implementation of such a system will in future favor e-bikes whose battery types are available at the change stations of the plant and can be replaced there at any time. This is how the standardization is driven. Some e-bike buyers are disappointed when they realize how much the capacity of their battery will decrease over time, especially if the bike is often left unused. A system as described offers the e-biker always good charged batteries, because they are much better, that is, used by many. Because the purchase of new batteries is carried by many users, the purchase price is allocated to many users and thus cheaper. One pays only the use, namely the electric charge. In addition, the entire battery life of a system and its replacement stations is always checked constantly and inadequate batteries can be immediately recognized and replaced, from which the user notices anything. He can always get a charged battery within easy reach and need not worry about the whole store and a place or place to shop. claims 1.
