Description

A method for automatic loading of fully or partially electrically operated vehicles and arrangement for producing a charging contact

technical field

The invention relates to a method for automatic loading of fully or partially electrically powered vehicles by means of an autonomous vehicle motion and an automated loading process, and associated devices, and arrangements for charging a power accumulator of electrically powered road vehicles.

State of the art

The share fully or partially electric vehicles in the total vehicle consisted will increase. A crucial task is the efficient and convenient battery charging. In general, due to the battery loading residence times / charging times by manually connecting the vehicle to an external power source to charge certain places. At present, the charging contact between the charging station and vehicle is made by manually plugging the cable connection. Electric vehicles currently usually have sockets fitted to the vehicle, compared to the usual fuel tank filler neck of vehicles. The driver connects the vehicle sockets manually by means of cables to the power supply sockets or fixed power supply cables to the loading points. Which is usually the cable for normal charging overnight at the residence or during the day at the workplace differ from the cables and connections for fast charging during the rest of motorways with a correspondingly high current necessary protection. The presence of people is basically required to initiate charging and perform. This means that the charging process can be cumbersome and costly.

For the manufacture of conductive or inductive charging contacts with a fully automated guided vehicles that travel autonomously and precisely to the loading station special solutions are known, such as the loading on the ground contacts option. The vehicles can be automated due to their automated tracking and fixed mounted charging contacts on their specified roadways charging stations and precise approach and make contact automatically. The connection of the store is then usually by the master control of the system.

these solutions are not applicable for vehicles of road transport.

The invention has for its object to mitigate one or more disadvantages of the prior art, or to be avoided. inventive solution

The object is the method, solved by providing a method for automatic loading of fully or partially electrically driven vehicles, characterized in that: a) a vehicle is used, which is equipped with: i) sensors for detecting surroundings, navigation, and collision avoidance; ii) a vehicle control for self-controlled driving of the vehicle; iii) a charging system for electrically charging the vehicle, and vi) at least one charging contact which is operatively connectable to at least a charging contact of the charging station at the loading location; b a load location is used), which is equipped with at least one loading station including at least one charging contact, which is designed operatively connectable to a charging contact of a vehicle to be loaded; c) the vehicle starts at an arbitrary starting point in a transfer region; d) the vehicle itself controlled drives a selected load location; e) at the selected load location, there is a charging contact between the vehicle and the charging station of the loading location; f) the vehicle itself is controlled leaves the loading location and starts up a selected acquisition region.

Device side, the object is achieved by providing an arrangement for producing a charging contact from fully or partially electrically powered road vehicles, comprising a) an electrical contact which is operatively connected with a power storage of a road vehicle; b) an electrical contact which is operatively connected to an external power source; c) a leading guide which is formed such that the two electrical contacts are at least laterally aligned to each other so that it directed to a

Contact may occur between the two contacts; d) a positioning aid for the road vehicle, which is designed such that the road vehicle is fixed in a direction of travel, the two electrical contacts are so operatively connected with each other by entering the fixed position that a loading contact is made and the current memory of the road vehicle about the external power source can be charged. By the inventive method considerably more times can be used by completely or partly electrically powered cars, to perform a charging process. The driver no longer needs to be involved in charges.

The fully or partially electrically powered vehicles, such as road vehicles, while close modern vehicle and drive technologies, such as pure electric vehicles and all hybrid variants, which work with power storage batteries, accumulators appropriate capacity and electrically driving at least temporarily or parallel. This may for example be passenger cars, vans, trucks, commercial vehicles and / or buses.

The vehicles are equipped with sensors for detecting surroundings, in particular to determine its own position. Furthermore, the vehicles are equipped with sensors for autonomous vehicle navigation, which allow an autonomous self-directed driving the vehicle, as well as sensors for distance and clearance measurement that serve to collision avoidance. In addition to different sensor principles camera and laser-based measurement principles, supported by on-board odometry method in outdoor and indoor areas are advantageously useful, in the outdoor area additionally supported by satellite-based positioning. Appropriate technologies are known in the art.

The vehicles have a vehicle control that allows an autonomous, self-directed movement of the vehicle. Such control systems are already known and an example to those skilled in DE 102005029336 A1.

The vehicles have a charging system for electrically charging the respective on-board storage system. This charging system is operatively connected to charging contacts which are arranged on the vehicle such that the charging contacts are accessible. The charging contacts are formed so that they are operatively connectable to at least a charging contact of the charging station at the loading location and there is a charging contact, which allows the loading of the vehicle's own storage system.

In the inventive method, a charging spot is used which is equipped with at least one loading station including at least one charging contact, which is designed operatively connectable to a charging contact of a charge vehicle. The charging contacts are formed so that there is a charging contact, which allows the loading of the vehicle's own storage system. The case concluded next charging contact between the charging station and vehicle can be electrically or inductively designed. The charger contact load location may be point-like formed at a location or linear manner along a roadway or rail section. The charging contact between the vehicle and the charging station can be made automatically or at the direction after reaching the loading station. The charging contact can be released automatically or at the direction after the loading operation. In particular, the charging contact between the vehicle and the charging station can be made in that the charging contacts of the vehicle and / or are automatically deployed after reaching the loading station and operatively connected to the charging contacts of the charging station. The charging contact with the vehicle can be automatically prepared by sensory controlled robotic contact part of the charging station, the charging contact of the vehicle is detected by sensors and the kinematics is controlled according to the contacting.

The load location may be designed so that it has one or more loading or waiting lines. On a loading or waiting line several vehicles can find space. The load line or waiting line is designed so that it has an approach position and a final position, wherein the self-controlled vehicle starts the approach position, then autonomously self-controlled to the front vehicle runs on a first minimum distance and then, one after aufrückt on sensory minimum distance to the front vehicle until the end position of the line is reached.

In the inventive method the vehicle can start at any starting point in a transfer region. A transfer area can be any area here, which is so situated to the used mount location that the charge vehicle can reach the selected place of loading in autonomous self-directed drive from the transfer area. The collection area is thus a virtually defined area which can vary and may depend, for example, vehicle type and / or state of charge. In general, the transfer area is the area in which the driver turns off the vehicle before a charging process is initiated. In the transfer region, the driver can leave the vehicle. There, the driver is from the direct control of the vehicle. Preferably, the transfer area is not simultaneously charging location.

The vehicle then controls autonomous and self-controlled to a selected load location. Systems, which allows such a self-controlled traveling of a vehicle from a view point toward a specific destination by using the specified street and road conditions and to avoid collisions and threats, are known in the art. In this case, sensors of the vehicle are used. In particular, the selection of a charging map, which will be approached by the vehicle itself is controlled carried out according to specified criteria. the loading location is preferred in accordance with the charging requirements, the specified residence time and / or the vehicle parameters are determined. On Offloading arrived, the vehicle moves itself controlled in a loading position relative to the loading station of the load situation, so that a charging contact is formed. At the selected load location, there is a charging contact between the vehicle and the charging station of the loading place. It allows charging. A charging contact may be formed for example by tailgating or starting from the automatic movement out. Preferably, the production of the contact to the automated conductive or inductive charging of the vehicle can be carried by the vehicle, for example, formed by the collision with contacts, or by the extension of contacts at the bottom of the vehicle toward the floor surface to be in accordance with punctiform or linear manner secure conductive or inductive power supply devices of the charging stations and their Zuscha- TION to load. Alternatively, the preparation of the contact to the automated conductive or inductive charging of the vehicle by control commands of the loading station takes place in which a robotic device at the loading station, the connector or the contact site sensorially determined and establishes the contact by mechanical movement conductively or inductively and according to the instructions of the master control again solves. With this solution constructively different charging contacts and different contact locations are treatable. At the instruction of the vehicle controller, the switch-off and release of the conductive or inductive contacts from the loading station takes place after charging.

The charging contact may, for example over a predetermined or an indefinite period or on demand.

After solution of the charging contact the vehicle leaves the loading site and self-controlled drives autonomously self-directed a selected tender area. A take-over zone may be any area here, which is so situated to the used mount location that geladende vehicle can reach the selected acquisition range of autonomous self-controlled ride. The principle selectable over zone is thus a virtually defined area which can vary and may depend, for example, vehicle type and / or state of charge. In general, the take-over zone, the area which the driver determines to take the vehicle back to reception. Preferably, the take-over zone is not the same loading location.

In the transfer area, the driver can board the vehicle again. There, the driver regains direct control of the vehicle. In particular, the vehicle after a predetermined residence time and / or at the direction of the driver or a Ladeortsystems may after completion of the charging operation, leaving the self-loading location and approach a selected acquisition region. The inventive method can be configured such that either the transfer area or the transfer area, or both the handover and the take-over zone simultaneously load location is / are.

The charging location and the vehicle used may each include a communication interface that enables a preferably direct communication and a preferably direct data exchange between the vehicle and load location, it being designed to communicate via wireless, cellular, optical, cable connection, RFID or the like. In particular, the communication interface of the vehicle and the charging place may be configured to communicate with different loading places and / or is possible with various vehicles. In particular, the charging location may include a Ladeortsystem and / or the vehicle used include a loading assistance system.

In a preferred form of the method the power storage of the vehicle with the approval and under the requirements of the current job can be used as a stream buffer of network energy by at existing charging or power contact a Ladeortsystem corresponding to the current availability, decides when and how long runter- at the respective vehicle or not shared, that is, whether current is drawn from the network or fed into the grid. The execution is carried out on the vehicle load control.

The present invention also relates to a Ladeortsystem comprising: a) a transmitting and a receiving unit that allows communication with an inventive charging assistance system; b) a memory unit; and c) a computing unit that detects incoming data of a charging assistance system, offset and outputting a result that data can be made in which are sent back to the loading assistant system, or are transmitted to a charging station.

In particular Ladeortsystem the invention may comprise a master control, in addition capable of communicating with a vehicle control for self-controlled driving a charge vehicle such functional, that the vehicle is guided to a selected load location.

For the purposes of the invention, a charging location may also consist of one or more load lines. For this purpose line-shaped charging stations, loading lines in sections or continuously from the transfer locations to transfer locations are available at loading points. Load lines can thereby be consequences punctate or linear charging contacts. A vehicle can continue on a load line and load in the state, for example for the advantageous inventive process: moving up to the front vehicle, pause, lower charge contacts, switch, load switch off, lift the charging contacts, continue, etc. This automated process is both fixed point-like charging contacts available and on any virtual load positions on load lines. This applies to all handover, takeover and loading points on all conductive or inductive charging lines as parking garages, for holding tracks as load lines before crossings, loading lines for loading on side parking lane along roads or road sections and also preferred routes in depots, factory yards, logistic yards etc., which will be available with progressive infrastructure development.

The automated loading of completely or partly electrically powered cars may be carried out in the inventive manner even while driving, the vehicle is performed automatically on the appropriate load line by precise sensor-controlled navigation while driving from a transfer region in the vicinity of a loading location, ie to the load line automatically cuts in and out on this at a controlled rate by sensor-controlled tracking along the load line autonomous precision and is loaded thereby and after loading or end of the load line track out in

is over section taken back by the driver while driving.

Charging can be done in charging lines along on designated road sections eg in urban areas, for example, for the supply, bus or at loading points for stationary se traffic on communication lines, access roads with restricted speed, on suitable roadways, even in depots, factory yards, logistic yards etc. ,

Charging while driving can be done in appropriate road / motorway / loading lanes that are equipped with appropriate charging infrastructure and on which the vehicles through automated reliable tracking with a nominal travel / charging

/ Autonomously moves recommended speed and can be loaded.

In addition, the invention also relates to a loading assistance system, comprising: a) a transmitting and a receiving unit that allows communication with an inventive Ladeortsystem; b) a display unit on which the user data is displayed optically and / or acoustically; c) an input unit with which the user can enter data into the loading assistance system; d) an arithmetic unit that selects charging places taking into account predeterminable parameters. In particular, loading assistance system according to the invention may be characterized in that via the input unit, a setting is adjustable, in particular a timing at which the vehicle is supposed to be at a fixed Pickup and / or a range specification, which is at least accessible after completion of charging.

The loading assistance system according to the invention may be configured such that a Ladeortsystem vehicle parameter, particularly vehicle dimensions, type, -ladekontak- ttyp, charge state and / or desired residence time can be communicated.

The loading assistance system offers the driver while driving in the transfer area of ​​existing charging places, lines, if desired, or when the measured load required, the "Transfer" option that the driver can confirm. The collection area is any vehicle position while driving near a load line, loading lane., for example, a position on the loading lane itself with the start of the charging place, the charging line is signaled to the driver. Or, the vehicle is, for example, in the fast lane of a loading track with load line from which it then self-driven autonomously after delivery out of the movement is guided to the loading track with load line, that is sheared on this one load line. the vehicle is then for charging by the vehicle control by precise sensory controlled navigation and having a nominal travel speed for loading and regulated charging contacting continued with the intended target speed until the handover , Preferably from the beginning to the end of a load line of a road section or of the time of a driver's decision to handover to a load line of a road section until the decision of the operator to acquire.

At the end of load line, the driver is signaled the end of the load line and offered the takeover. The take-over zone is then the automatic tracking with recommended speed after the end of the load line, on which the vehicle is continued until the takeover automated by the driver. If the driver does not take the vehicle over and veering, the vehicle is track-guided further automated if necessary until the next loading lane road section with load line and then preferably with automated handover.

The loading assistance system are the exact coordinates of the loading places, loading lines, the beginning and end of the current or next load line and the coordinates of the way points, the charge recommended speed, local feed data and the region features for precise vehicle location according to the invention (as a world model data from Ladeortsystem and or loading assistance system) as target data. From their comparison with the constantly sensorially determined position data from the environment features, and the vehicle data as actual data and having regard to their own driving geometry, the steering angle control and the speed control of the vehicle is calculated and given to the vehicle control for precise navigation and tracking.

The invention also relates to a charging system comprising an inventive Ladeortsystem and an inventive vehicle-side load assist system, which are matched to each other functionally, that a preferably direct communication between a Ladeortsystem and a charging assistance system is possible.

The invention also relates to a vehicle with complete or partial electrical drive comprising an inventive charging assistance system.

Finally, the invention also relates to a charging location which is equipped with at least one loading station including at least one charging contact, which is designed operatively connectable to a charging contact of a charge vehicle and an inventive

having Ladeortsystem.

At the instigation of the driver, the vehicle can communicate to the Ladeortsystem via the charging assistance system in the transfer area of ​​a charging place the need for charging, the charge level and the vehicle / load parameters. The Ladeortsystem or charging assistance system can accordingly determine an appropriate charging station. The Ladeort- system may then, according to the selection of the charging place, the navigation data to the vehicle to communicate, as a prerequisite for autonomously start the charging station. In a particular embodiment, the driver can preferably agree by closing the vehicle, the transfer of the vehicle control to the master control of the Ladeortsystems. The Ladeortsystem then takes over the master control of the vehicle and the vehicle thus passes into the autonomous mode. The vehicle can then drive the vehicle control under consideration of the requirements of the control system autonomously of certain of Ladeortsystem for the vehicle charging station. After loading or after expiry of the dwell time or after call or at the direction of the control system of the vehicle from the charging station autonomously and automatically moves to the desired take-over area of ​​the loading place. The takeover by the driver in the transfer area, the Ladeortsystem are on the master control control of the vehicle control, and the vehicle leaves the autonomous mode.

In particular, the driver can tell the Ladeortsystem before or during the transfer a planned, estimated, and / or desired residence time and / or a scheduled date of acquisition. Using these data, can optimize the charging process cost-effectively the Ladeortsystem. The Ladeortsystem can select on the primary control on the basis of the charging needs, requirements, temporal conditions and / or transmitted by the car parameters and load parameters a suitable charging station or a waiting station or a maneuvering or reacting of the vehicle and optimize the charging process according to the object.

The driver can at any time enter into a dialogue with the Ladeortsystem, preferably via a charging assistance system of the vehicle charging system and / or directly or indirectly for example via a terminal or a dialog interface in the vicinity of the charging spot or via mobile devices from any distance to the loading site.

The driver can at any time retrieve at least the current charge status or the range thus available via the Ladeortsystem or directly from the loading assistance system. The driver can influence through communication with the Ladeortsystem and indirectly with the loading assistance system and / or change the dwell time or acquisition date at any time. The Ladeortsystem can adjust the charging process it and, especially in direct premature recall of the vehicle, inform the driver of the consequences, for example on the current charge level and its current available range.

The communication interface and the communication protocol of the charging system between the Ladeortsystem and the charging system of the vehicle can be designed such that it is load location-independent, which means that the instructions, data exchange and / or commands from the Ladeortsystems for each vehicle are clearly evident. For example, the loading location transmitted map information for each vehicle dahin- fully understood that it can clearly determine its own vehicle position so that at any time, communicate the Ladeortsystem and can be used for automatic navigation.

The driver can control the vehicle at the transfer authorized Ladeortsystem and pass the master controller so that then is used to communicate and / or any authorized data exchange between the vehicle control and the Ladeortsystem.

After reaching the loading station of the charging contact can automatically for charging the battery of the vehicle are made automatically by the vehicle charging system and / or by or on the order Ladeortsystem. The charging contact can be automatically released again after loading. The charging contact may be configured electrically or inductively.

The vehicle can be measured at the transfer to the Ladeortsystem for security to detect any possible differences of the current dimensions of the vehicle parameters communicated. It can be detected by sensors, whether persons, organisms or dangerous goods, insofar as sensory detectable, are in or on the vehicle.

The vehicle controller has access to the actuators for the steering, braking and accelerating, the so-called drive-by-wire technology, which is required for autonomy and assistance functions. The vehicle control is used inter alia for route planning, control of driving behavior. The vehicle charging system is used inter alia for controlling charging, and to control the charging contacts.

The vehicles are also equipped with a communication system that allows sending and receiving unit for the preferably direct communication with the Ladeortsystem.

A loading assistance system serves as a man-machine interface in the vehicle to dialogue with the driver, in particular interactive presentation of the vehicle and charge state of the respective range as well as the navigation information and dialogue with the Ladeortsystem. The charging places with Ladeortsystem comprise at least a charging unit and may have with the adapted to the respective local conditions arrays of charging stations and / or load line charging areas.

The loading assistance system informs the driver in the vehicle via the charging status and remaining range of the vehicle. In a voyage accessible to the driver loading places with available free charging stations along the route are offered. based on the information and its needs the driver decides which charging location for charging the current memory he wants to select and then obtains the navigation information with which it is fed to a transfer area of ​​the selected charging place. Facilities with charging places like service stations, shopping centers, etc. can have their position data and Ladeortdaten, set the map data of the navigation systems.

The driver can determine the expected length of stay or the desired acquisition time, to be loaded minimum range and / or the desired charging mode, in dialogue with the loading assistance system of the vehicle for optimized loading. The requirements will be communicated by the loading assistance system of the vehicle charging system to the Ladeortsystem.

The Ladeortsystem sends a confirmation / Offer as feedback. the offer can be used as a reservation of the charging station at the loading site ahead of the loading site. In the transfer realm of driver confirms the offer and thus selects the autonomy mode. The autonomy mode starts after getting in the transfer area with the locking of the vehicle.

The autonomy starts in the transfer area (entrance with driver - Driving the charging spot driverless, autonomous) and ends in the transfer area (Driving directions from loading site driverless autonomous - exit with driver).

The Ladeortsystem sends instructions of the control system for autonomous driving to the assigned stand and the necessary navigation data to the vehicle. The

Master control is the high-level control, mission control.

The vehicle starts autonomously along a planned Wegroute / T rajektorie with independent regulation, as well as autonomous collision avoidance towards loading station, either directly to the predetermined base station, or over predetermined intermediate stations, possibly with the reaction and after the loading operation, if necessary, through waiting position or hold.

The desired or updated at the time the vehicle arrives at the desired take-over zone an autonomously. the autonomous mode is identical by opening of the vehicle with the key / key / driver terminated. The driver takes over the loaded vehicle.

The optimization of the charging process depends on the configuration of the infrastructure of the charging spot, the functionality and number of available charging stations and demand, ie the associated best possible coordination of the needs of all vehicles at the loading site. The optimization in the interest of the customer then makes a mark of quality and a

Marketing argument represents the respective charging place.

Changes in requirements of the desired acquisition time are always on long distance call or locally via mobile phone, and / or via the Internet or through service terminals, etc. possible. These changes, if necessary, to change the charging process, according to the remaining length of stay or the available remaining charging time and lead to the calculation of the consequences of changes in the expected state of charge and the expected range with a corresponding message to the driver dialog with a request for confirmation , In general, it is the goal that is a full charge and maximum range available on the acquisition date.

The driver receives when handing over the communications authorized for the purpose of access to the Ladeortsystem querying state of charge and reach and if desired of further operating and charging data of the own vehicle, for changes or reputation of the vehicle. Conversely receives the Ladeortsystem, if desired, the communication access to the mobile terminal of the user for the optional completion message charging. In case of premature call of the driver can specify a desired new acquisition date, as far as this is feasible. In case of direct Fahrzeugruf the driver, the earliest possible time of the acquisition is notified, that is, calculates the time the possibly required for the vehicle to turn off, undocking and to return in the take-over zone and from the time of arrival is calculated in the transfer area to the driver. The driver can also change the effect that he wants the earliest possible date a desired range (possibly with appropriate reserve), for example, 100 km plus 10% loaded, and then the Ladeortsystem necessary planning a quick charge for the differential charge and the driver the earliest possible date of acquisition calculated. If the driver accepts that Ladeortsystem changes the procedure accordingly.

The design of the charging contacts may differ constructive. A standard for charging systems is desirable but not yet the case. Differences result from different functionalities such as fast charging with high voltage, Normal store with household electricity from different standards, producers standard, constructive arrangements / versions on the vehicle. Different charging contacts on vehicles are treatable by the one universal charging stations or by assigning specialized charging stations by the Ladeortsystem. With the inventive automated solution this problem for the driver remains invisible. Heterogeneous charging systems can be integrated from Ladeortsystem. In exceptional cases Speziaistationen with service personnel may be useful to treat special and incidents.

The current storage of the vehicle can be used with the consent and under the requirements of the current current job as an intermediate storage of power energy by the master control of Ladeortsystems decide in accordance with existing charging and power contact current availability when and how long for the respective vehicle runter- or is uploaded, that is, whether current is drawn from the network or fed into the grid. The execution is carried out on the vehicle load control.

A waiting line in the transfer area preferably has a larger automated vehicle distance organized to facilitate manual swinging out of the vehicle after the takeover by the driver.

The automated provision of the vehicle for taking over by the driver, the pick-up in the desired time window is carried out, for example, by autonomous moving up of the vehicles in a transfer line or loop in the transfer area with a distance of the vehicles, the comfortable bypassing Boarding loading and ultimately the manual sheering facilitates the vehicle for the driver. The released gap is closed by the still waiting vehicles by autonomous moving up with this distance again. For long waiting vehicles an inquiry can possibly be done with the user and, if necessary, carried a return of the vehicle in the queue. Here, a reset, or reacting, for example, be carried out in a circular loop of the vehicle.

Using sensor system ensures that the aufrückenden autonomous vehicles on the approach and access to a vehicle whose stoppage or its stopping and running.

Preferably, the opening of the vehicle, by the driver to take over from the autonomous mode only in the designated transfer area and in the presence of the authorized driver without access by third parties take place, whereby only usually leave with opening of the vehicle by the driver the autonomous mode and in the manual mode is entered. The driver gets in, loads the vehicle if necessary and leaves driver controlled the transfer loop, the vehicles provided automatically move on.

By the autonomy of the vehicles and the uniform interface of the communication between the charging and vehicle control and the Ladeortsystem uniform definition of the instructions and uniform definition of the navigation data, any organization of the loading places with different handover / takeover and loading regions and variable arrangement of the charging stations are possible. So efficient, optimally adaptable to the conditions given organizational forms of loading are possible. The standardized communication interface is ladeortunabhängig, can be extended in their language instruction with basic instructions and of course for each vehicle, for example, Drive to location A; Go to line B; make / break, etc. charging contact

By the present invention an automated solution is achieved that vehicles automatically correct itself tight and space-saving according to the arrangements of the load ports with the respectively required minimum safety distance, for example in dense tracks with vehicles close behind one another as a block, for example 10 lanes a 10 vehicles behind the other with the linear charging contacts or any other charging places the charging mode or the vehicles adapted arrangements.

Preferably, the total loading logistics can remain hidden from the driver. The driver-side interfaces and behavioral routines remain the same. Premature fetching at blockwise tight arrangement is done automatically by reacting the autonomous vehicles eg Rangierschleife, comparable to a ring memory. The vehicle in the first position of the relevant line operates the loop and moves close to the last vehicle, the other vehicles will follow the desired vehicle in the first position of the load line is reached and this can leave. The following vehicles will move up and invite further. An example arrangement of a block with Rangierschleife (n) for the autonomous re-sorting of the vehicles is shown in Fig. 2. This solution provides high flexibility and efficiency and can be extended.

The vehicles will be sorted by Ladeortsystem according to the charging order and the planned takeover time logistically. The functional and structural design of the charging contacts of the respective vehicle due to the selection of the appropriate charging station by the Ladeortsystem.

The invention also permits a variable organization by Ladeortsystem to the effect that a fully loaded vehicle when needed can also be reacted to a place without a charging station, that is, it need not necessarily be over-capacity of charging stations may be present. A vehicle for an urgent fast charge is prioritized invited to correspondingly higher regular rate. A schedule longer stationary vehicle can be charged at a discount rate (less expensive), optionally at spatially more distant charging stations or other loading points.

Preferably decentralized handover / take places, for example distributed accesses to shopping centers, as needed, in the vicinity of loading locations distributed be arranged, that is, the handover may be different than the up location, or it can be changed by the user event, if the service from Ladeortsystem is offered and is then organized through the Ladeortsystem and the master control.

For distance rides fast full charge of electricity storage are traveling usually desired, often in places that are not familiar to the driver or unknown, for example at rest areas, truck stops on motorways or trunk roads, and car parks in cities. The fast-charge are necessary for long-distance journeys pure electric vehicles or desirable and environmental sense in hybrid vehicles. The rapid charging at a service station is then carried out for example during a break from driving of the driver. The driverless autonomy operation of the vehicle then does not count as driving time but as a rest period of the driver.

For local trips that do not require fast-charge, optimized full charges regarding expected predictable periods of residence to be organized. Preferred loading places are located at or near parking garages and / or -platzen, at places of residence to places of work, in inner cities, in shopping centers, restaurants, sports facilities, recreational facilities, tourism or cultural facilities, Park & ​​Ride facilities in public transport public transport etc.

Since the inventive solution allows a uniform, variable and scalable use advantageously in individual private sector minimal Ladeortsystem can be installed optionally manages several private charging stations. In extreme cases, the private Ladeortsystem can also be taken from the vehicle charging system, if it is, for example, the "Heimaf mount location and the map information of the charging location is stored in the vehicle charging system. Means reached position data (for example, GPS), the map information enabled. By means of current data of the vehicle sensors and comparing them with the map information is for example calculated by the transfer area at the front door, the trajectory to the charging station and autonomous approached. The map information may be stored in the private sector with the vehicle sensor once in the initial manual operation by traveling the route from the usual handover to the selected load location (transfer-transfer area to loading location and loading stations) (taught). The trajectory / the way will be charged to hand the card information and the sensory determined current situation, optimized and monitored by sensors driven autonomously.

This includes charging places with multiple heterogeneous "tightly packed" arranged a load ports, wherein the spatially separated handover / transfer areas in front of the house door, the lift can be in multiple garages, car, etc..

For example, the driver pulls up his front door, gets out, closes the vehicle door, the vehicle runs autonomously for charging spot (garage, carport, basement garage, etc.), and charges the vehicle's battery overnight. The driver calls or ordered the vehicle at the desired time the front door, the vehicle docked on time at the loading station off drives autonomously to the front door, the driver opens the vehicle door and takes over the vehicle.

In other places regularly used loading the card information also does not necessarily have to be completely transferred each time. Changes can then be reported as an update.

The invention is also suitable for an automated car rental or car sharing service from fully or partially electrically operated vehicles as a simplified and convenient interface between the public and private transport, including automotive order (place transfer area and time) via mobile terminals, providing fully charged electric vehicles desired take-over zone of outputs directly in front of hotels, railway stations, airports, etc. and ultimately to the return individual use in a transfer region also directly in front of the inputs of the desired destination without additional shuttle. Then automated starting up a charging spot and preparation for the next user. Waiting at loading station possibly also as a power buffer. In addition, the Ladeortsystem may include the preparation of the vehicle in the automated process, in particular the regular or sensory veran- led washing operations, a robot cleaner, the automated optical and vehicle technical inspection.

Moreover, beyond the loading process more service operations can also for private use at specific loading points through the Ladeortsystem be included in the automated process flow at the loading site, such as automated washing operations, refueling (eg hybrid vehicles), Güterbe- and unloading in shopping malls, also controlled the control system when the Ladeortsystem it offers and when it is desired by the user.

The inventive method can be applied in urban transport of goods with fully or partially electrically powered vehicles. In distribution centers and logistics centers or at customers with multiple loading ramps, the combination of loading and unloading offers, ramps with charging stations, in which case the start of these stations in the same way with automated is.

The inventive method also offers the flexibility to include equipped with conveyor system automated or semi-automated parking facilities / parking garages as payload portions of a charging map in particular in urban areas, this integration for the user remains hidden and thereby just the previous lack of automated parking garage art are overcome, in particular the rigid "manual" handover, transfer principles, for which congestion and waiting time for the driver and other road users arise with the inclusion in the inventive automated solution the shortcomings of such systems referred to on the one hand eliminates, on the other hand takes place an appreciation as a charging places in the inventive sense..

The time throughput for the user is improved and waiting times are avoided.

The integration is performed by the master control, preferably at planned shut-down of longer. In this case, charging contacts are then provided for automatic contacting with the power supply to the plots. The related process flow (for example: control of the conveyor system) is integrated by the master controller in the overall process. For the driver, the entire Ladeortorganisation is invisible.

First and foremost, it must be assumed that the areas where the vehicles move autonomously, in particular the loading areas, are not intended for mixed operation, since automated to save space without driver and on / off access to the charging stations "close together" is docked. There is on the other hand no reason to mixed mode or autonomous operation in the public excluded. in these particular areas then this technical solution, in addition to the requi- dernissen compliance with collision avoidance and the speed limit during the autonomous driving automatically correspondingly larger safety distances guaranteed at reasonable speed.

This variant is particularly advantageous when handover transfer areas of the loading places are placed directly in front of the inputs / outputs of the respective target locations, for example before house, hotel, company input, etc., and thereby at least a short term autonomous drive to the public to the entrance to the loading areas and after loading is carried back. In this case, a larger free space is secured than in the space-saving organized loading areas around the vehicle contained in the transfer take-over zone. Thus getting in and out as well as the loading and unloading easier.

Example of "autonomous start-up with driver '

The driver is driving in public transport until his driveway (parking garage, car park, car lift, etc.), at his residence, place of work, hotel / motel, car-sharing site, car service, etc. It is in particular places where personal, private, or assigned to the vehicle charging stations at which entry and exit, loading and unloading can be carried out easily and safely exist and.

The entrance is here also the transfer area. The driver starts, for example, driver ID, the autonomous mode. In this case, but not by closing the unladen vehicle from the outside but through a command of the driver from the inside. The driver and possibly other inmates remain in the vehicle. The autonomous mode takes control of the vehicle and binds more automated processes in the Autonomous Driving one, such as the opening of the gates, barriers, the barrier, calling elevator, select target floor, etc. The vehicle navigates autonomously to the charging station to dock , the contacts are closed and the charging contact side released. The driver starts the charging process of its load assist system in the vehicle if necessary with desired requirements or with his remote control, or a mobile terminal from the inside or the outside. Then, the network connection is made to load and the battery is charged in accordance with preset or program or vice versa fed power from the battery to the grid. It can be activated an immobilizer during charging. One or more doors can be opened during charging and closed, for example for independent loading and unloading, as well as entry and exit. Thereby, the vehicle may for example be loaded in calm before the departure time and take place in parallel to the battery immediately before the start.

If the transfer area to the loading station no turning possibility of the vehicle consists (eg only accessible from one side vehicle-elevator) and / or when a rear docking onto the charging station is desired, it may be advantageous from the transfer area with an initial autonomous maneuvering and (rear-facing entering the elevator for example) to drive subsequent autonomous reverse drive to the charging station and then to start after loading and after autonomic drive to the take-over zone from there with a forward travel in public transport.

The solution is beneficial for all users whose charging stations are also exit / entry and / or loading and unloading, in secure, covered areas, but they are difficult and inconvenient to manually run. It is particularly advantageous for elderly and / or disabled people, and if for example the parking space for loading (charging station) is level with the house or next to or inside the apartment.

If it is for the user in that sense even more advantageous in front of the autonomous docking onto the charging station to perform at a position, for example with a larger space or with a shorter path to the destination, for example, immediately before the door the switching on, Getting, loading or unloading, then the automated process can be designed such that to serving stop occurs, ie autonomous drive with driver from the transfer area (entrance) to the exit and unloading, autonomous continue without a driver to the loading station and docking with automated loading, after loading call and autonomic drive without a driver for entry-level and place of loading, autonomous continue by drivers to take-over zone (exit) and assumption of responsibility by the driver.

Particular advantages of the invention

The advantages of the solution described are to increase convenience of use and thereby to increase the acceptance of use of fully or partially electrically operated vehicles by automated loading processes of the current memory and by full or quasi-automatic manufacture of the charging contact. Thus increasing the proportion of vehicles is indirectly accelerated on the basis of renewable energy sources and ultimately a saving of fossil fuels and a reduction in Cθ reached 2 emissions.

Facilitating the use of electric vehicles in particular by avoiding the difficulty of regularly required prospect of charging stations and manual uncomfortable, annoying and sometimes "dirty" arrival and Abkabelns of the vehicle, in principle, between each trip, reached in both the Passenger as well as commercial vehicles. the inventive autonomy function is not available for the driver who regularly time-consuming search of a free and appropriate charging station with corresponding driving and pedestrian paths and laden with risks and stress docking with charging stations especially in space-saving dense arrays of charging stations. benefit the driver / user is the freedom from stress and time savings achieved. an important advantage in this context is the damage prevention by the present invention automated solution. in contrast, in the permanent "manual" approach to loading stations (parking) in tight either self-inflicted injury or damage in the conflict to be expected car parks with other road users of vehicles, people or infrastructure. Of these, older road users will benefit in particular, which are particularly dependent on mobility and as users of electric vehicles are predestined.

By the present invention automatically organized constant charging readiness of the vehicle batteries to the charging stations at any storage place, and thus the high availability of storage capacity at the network results firstly in considerable cost savings for the user through the utility excess regenerative energy (savings rates, at night, in particular wind or stored energy daytime solar energy). Second, optional, if allowed by the user, a further benefit, and ultimately gain an economic benefit by the potential of efficient electricity arises for him between storage of energy peaks of renewable energies and the subsequent reinstatement regeneration to the network with the appropriate compensation of the feed power to the battery - / vehicle owners.

Space-saving use of land for stationary traffic: As the vehicle automatically without drivers to load location, the vehicle can therefore be parked to save space in a smaller space to load. Benefit is the reduction of road surfaces for stationary traffic. Uniform universal solution with high flexibility by adapting to any charging places with variable arrangements of charging stations and the inclusion of variable / heterogeneous charging interfaces. The inventive system also offers the advantage to include automated or semi-automated parking garage-handling technology in an automated total solution and achieved to eliminate the shortcomings of the rigid "manual" handover, takeover principles, where congestion and waiting times for the driver can arise and flexible universal solution to achieve.

For car sharing and car rental concepts can be combined with the inventive automated solution to reduce costs (staff costs, damage prevention) and quality improvement as well as a future-oriented and customer-oriented appreciation reach up to higher public transport acceptance by improving the interface between public and private transport ,

Finally, the arrangement of the invention comprises a contact set for electric vehicles, in particular a convenient, reasonably priced, retrofittable solution in particular for the private sector, a lightweight vehicle-side contact set for mounting on the vehicle, and a compact contact sets at the charging station for mounting, for example in the garage.

To be able to charge the power storage of a road vehicle, is a charging contact between an electrical contact which is operatively connected with a power storage of a road vehicle and an electrical contact which is operatively connected to an external power source prepared. The term contact is an array of electrically conducting materials to be understood that allow a current to flow from one contact to another contact at the connection of two of such, coordinated contacts adapted to charge a power storage that is connected to one of the contacts operatively connected to current which is provided from a power source which is operatively connected to the other of the contacts. A contact according to the invention may include a positive pole and a negative pole of a direct current or alternating or three poles for power and optionally include other conductive connections or an inductive contact. The electrical contacts of the road vehicle and the external power source are designed so that when forming a charging contact an electrically conductive connection arises between the current memory of the road vehicle and the external power source. It may be galvanic or inductive contacts. The contacts can be configured for example as plates, ribbons, plug or in any other manner which allow formation of a stable charging contact. the two contacts are preferred in this case matched to one another that they are related, knife-vaginal relationship or male-female relationship in a kind of key lock. You can be coordinated and comb and / or blade-shaped. A charging contact between the two contacts can be prepared for example by the fact that the contacts enter into each other, bring up to each other and / or are pressed against each other. The force which is necessary, to form a charging contact, for example, be provided in the positioning or directly or indirectly by the vehicle weight by the movement of approach of the road vehicle. a contact is preferably at least only brought about by a triggering event in a position in which the contact is to form a charging contact are available. Such an event, for example, the movement of approach of the road vehicle in the positioning may be directly or indirectly, the vehicle weight. By the movement of approach and directly or indirectly by the vehicle weight, the contacts can be pressed or extended and pressed or retracted to retract or swung. In a particular variant, the contacts of the road vehicle may be mounted on the vehicle floor and a charging contact are formed by collision with the ground contacts or by retracting / pressing of resilient contact connections. The contacts of the road vehicle may be a charging contact and by retracting / pressing of resilient contact connections are formed also in the direction of forward / frontal, lateral / laterally or rearward / rear mounted on the vehicle. In particular, the electrical contacts can be configured such that the contacts retract by the movement of approach of the road vehicle in the positioning together and / or sequentially ascend to prepare a charging contact.

In order to prevent that one of the contacts from being damaged when manufacturing the charging contact, at least one of the contacts (or both) may be resiliently mounted, so that a force exceeding a force which is necessary to a charging contact form, can be collected and not to damage to the inventive arrangement leads. Suitable resilient bearings are known in the art.

The inventive arrangement includes a leading guide which is formed such that the two electrical contacts are aligned to each other at least laterally so that it can come to a communicating contact between the two contacts. In this case, the leading guide is positioned in the assembly such that the two contacts, aligns with entrance of the road vehicle in the positioning automatically without manual adjustment to one another such that a charging contact can be formed successfully. In particular, the leading guide may comprise a preceding mandrel, and a funnel which is designed such that the projecting pin is inserted into the funnel, wherein either the funnel or the projecting pin is connected to the road vehicle. A leading guide may for example comprise a funnel-shaped guide and an insertable therein preceding mandrel. In a particular embodiment, the alignment (centering) of the two contacts can be carried out sequentially in that a self-centering guide (ie funnel-shaped guide projecting mandrel moves into funnel) on the vehicle a spring-mounted contact block a loading station to the fixed contact block of a road vehicle centered and thereby the Anfahrtoleranzen compensates particular horizontally, but also vertically and usually only slightly in the remaining degrees of freedom. In another variant, the leading guide the horizontal alignment of the contacts with a fork-like lateral guide of the stationary charging contacts can be achieved.

In particular, the contacts in the non-contacted and / or in the contacted state may be protected by the cover to the touch. A protective cover is then simply removed to form the charging contact. In particular, the arrangement of the invention may be designed such that the contacts are covered again in the current-carrying state. Uncovering / opening the protective covers of the contacts to the vehicle contacts and the stationary contacts can as physically free Push /, be achieved by force contact from the movement (approach).

The inventive arrangement has a positioning aid for the road vehicle, which is designed such that the road vehicle is fixed in a direction of travel, the two electrical contacts are so operatively connected with each other by entering the fixed position that a loading contact is made and the current memory of the road vehicle through the external power source can be charged. The positioning may be formed such that at least one wheel of the road vehicle in a traveling direction of forward and backward is optionally fixed, so that the vehicle does not continue in the direction of travel, yet can roll back. The positioning aid may comprise at least one wheel stop, a threshold or a parking barrier. In particular, the positioning aid may have a slightly over-propelled threshold, which is preceded by a wheel stop, a further threshold or a parking barrier in a direction of travel of the road vehicle and is configured such that a wheel of a road vehicle between the easy to over travel threshold and the wheel stop, the further threshold or the parking barrier is fixed and thereby a backward rolling of the road vehicle is prevented during the loading operation. The positioning can be a wheel well.

The arrangement according to the invention may additionally comprise a device that is configured to be the approach movement of the road vehicle in the positioning of one or more of the electrical contacts brought into a position which allows the formation of a charging contact. In particular, the device can be configured such that by the Auffahrdruck of a wheel of the road vehicle and / or the vehicle weight at least one electrical contact to form a charging contact is positioned. For example, this device may be a (lever) have mechanism which causes extended by the Auffahrdruck of a wheel of the road vehicle at least one contact, pivoted, raised or brought in some other way in a suitable position to form a charging contact. This can be achieved for example with a cantilevered resilient running surface of the positioning wheel stop.

A particular embodiment of the inventive arrangement is characterized in that produced from the movement of the vehicle out during start of a charging station the charging contact is by the charging contacts at least lateral (horizontal) aligned on the approach by a leading guide one another or are centered and the position is fixed in the direction of travel by a wheel stop.

In particular, at least one switch can be actuated by the vehicle weight and / or the Auffahrdruck a wheel which controls a release to the power switching. In a further embodiment, the arrangement is such that only in a positioned properly by the positioning road vehicle, at the correct vehicle contact and authorized commanding a power switch-on or a network contact can be made.

In particular, the arrangement of the invention can be designed so that is secure in that the road vehicle can be moved from the loading position only when the power supply / charger contact has been turned off beforehand.

In another embodiment, the assembly is configured so that an electronic Ladewegfahrsperre ensures that the vehicle will not start / move, as long as power contact exists, while still access for loading and unloading of the vehicle in the loading state to the normal vehicle-Key allowed (eg for parallel loading and battery charging until just before departure!) remains.

The previous description of the invention is based primarily on a mechanical arrangement of the functional elements that can be realized exactly, however, so in a manner analogous to all or part of electromechanically or electronically and is designed as assembly. For example, the mechanical stop to the position fixing can also be carried out virtually by measuring sensors and accurate initial braking position with immobilizer.

Also, the leading guide and thereby the lateral alignment of the charging contacts to each other may be performed by sensor-guided vehicle control system and / or sensory (lateral) control of the contacts. The positioning allows precise position accurate alignment of the vehicle at the charging contacts and fixing in longitudinal / driving direction by sensory controlled or controlled by signal transmission initial braking / starting.

An electronic immobilizer ensures that a secure power connection is performed only in the contacted state.

Also, the contact formation may be performed by sensor-triggered and / or controlled extension / pivoting / raising / lowering of contacts, as well as vice versa the disengagement of the contacts after loading.

An advantage of the virtual fixation / immobilizer, it is also that the vehicle can continue to run after loading sensor-controlled in the direction of travel, which corresponds to the principle of charging lines described (inductively or conductively).

The inventive arrangement can also be advantageously fully inserted into parts of the quasi-automated wireless charging of fully or partially electrically operated two-wheeled road vehicles or, for example, E-motorcycles, electric scooters, mopeds E-, E-bikes. Advantageously, the leading guide and / or the positioning in this case may be nierhilfe designed so that the vehicle is kept even during loading in the upright position, for example by form-fit or force fit in the loading position. The arrangement then replaced for charging the conventional two-wheel stand by a new e-charging two-wheel stand.

Example Automated charging electric / hybrid buses

In buses with energy storage (supercapacitors, batteries), the power storage may advantageously up at bus stops or on roadways or Fahrwegabschitten or be recharged, at stops in spots or a line section, inductively or conductively coils via galvanic contacts.

According to the invention, the conductive and / or inductive charging stations, lines, by the vehicle (bus) driven sensor-controlled automated so that a sensor-controlled precise alignment of the contacts to each other and a precise positioning of the charging contact is achieved at the load line, thereby providing improved when inductive charging efficiency of energy transfer and hence a more efficient charging (fast or higher amount of energy) is obtained, optionally wherein the lifting takes place with automatic lowering / application of the charging contacts, such as in the state respectively, the lowering of the zero gap and prior to continue. The position of the charging contacts at the stops is arranged in an advantageous manner in such a way to the stop, that in addition to the improved efficiency of charging by the automated position-accurate moving to the charging contacts, the safe and wear-free dense stops Driving downlines reached, whereby a higher comfort for passengers by level equal and almost complete free on / off access, an advantageous driver relief by sensor-controlled automatic vehicle guidance and collision avoidance and lower claims costs (eg avoid damage to wheels / tires by curb collisions in manual mode) is achieved for the operator.

Automated store for example in automated car parks

In automated car parks with pallet technology, the pallets can be provided with charging contact, wherein the contacting is carried out then either already during manual, assisted or automated input / driving onto pallets and the power switching immediately or at Palettenabstellort.

If the palettes are permanently connected to the mains, the power switching and network connection can take place immediately after the contacting. Otherwise, the current connection is performed only at the drop-off location of the pallet by a second make contact of the pallet to the network at space. In automated car parks without pallet technology, the charging contact and producing current connection takes place in the inventive manner to the off location of the vehicle.

Example Inductive charging while driving

The invention also provides an inductive charging while driving is possible.

When inductive charging while driving the advantageous precise alignment of the charging contacts to one another is a prerequisite of an acceptable energy transmission here first by the automated precision sensor-controlled navigation on the basis of environmental characteristics. Further, the inductively measured relative position of the charging contact to each other is used as an additional measured quantity for the fine control of the contact alignment. The reduction takes place in the air gap to improve the energy transfer by sensory control to the respective variable speed-dependent minimum gap. This lowering takes place in each case to the zero gap and prior to continue the lifting of the stand. The resulting current flow is used as an evaluation criterion.

The regulated depending on the speed lowered charging contact is monitored by sensors in the travel direction and the ground spacing controlled to avoid damage (by soil conditions, obstacles), depending on the quality of the roadway infrastructure or the road profile. The present invention also includes a use of an inventive arrangement for producing a charging contact from fully or partially electrically powered road vehicles, the road vehicle may be autonomously moved and / or wherein for the preparation of the charge contact no person in a road vehicle is present.

The inventive arrangement is used primarily for private reserved charging stations and for the regular battery charge and the network connection of batteries at the residence overnight or during the day at the workplace.

Moreover, the arrangement for reserved charging stations can be used for car or car-sharing service, but it also generally as a uniform standard solution.

provides the intended compact design of the inventive arrangement for charging stations / columns a closed assembly, which is electrically connected via assembled cable to the wall station. An adjustment of the zero position of the lateral orientable charging contacts allows the adaptation of the geometrical relationships between the wheel and arrangement of the charging contacts for the vehicle type in question.

Standardization of measurements is desirable. A mechanical or electrically controlled adjustment feasible. The wall station manages and controls the current supply circuit, charging and power grid connection. So far, the wall station is taken the charging cable and connected to the vehicle power socket.

The mounting of the assembly is preferably carried as Aufbodenmontage, flat on the ground similar to a game in Bumper roads or recessed into the floor or as a column in the room or with partial wall mounting, for example on the rear wall in a garage or parking garage.

Application inside: retract depending on the situation at the loading stations in garage, carport, in underground car parks, parking garages, etc. In general, it is preferred feed-forward start of the charging station into the loading station forwards or backwards. In many practical cases, however, only rear-facing start-up is possible.

Outdoor use: driving into charging stations in public spaces in parking lots with principles comparable foreign outlets with covers. The solution preferably serves to quasi-automated loading contacting during manual startup by individual driver, possibly also with the help of assistance systems or by automatic starting. By approaching the loading position, the tolerances are compensated by the device.

The quasi-automated mechanical production of the charging contact for charging of E vehicles, particular without additional auxiliary energy, ie quasi-automatic docking at the charging stations.

The approach may be generally, actively controlled propelled manually by drivers, pushed or pulled by the conveyor technology or via an inclined plane anrollend, at a low speed, carried out similar to the fold in the garage, that the production of the charge contact are connected with the remaining kinetic energy from the travel movement to

standstill

The tolerances of the positioning and alignment and the tolerances with respect to different degrees Anfahrkräften at individual driving style differences are compensated by a guided deflection of the contact retention, being achieved with a guided suspension and a floating bearing, the backlash and the game for the centering and tolerance compensation, and that after release of the contact, the return of the stationary charging contacts takes place in the middle neutral position.

Another advantage is the low wear guided centering and suspension of contacts.

The protective cover of the contacts on the vehicle and the charging stations are to prevent spray or rain water and to protect people, animals, etc.

The leading centering guide (ie mandrel tip) can also be used for pushing away / unfolding of the protective covers over the contacts. The power contact is maintained during the entire service life generally to load efficiently inexpensive electricity generated from renewable sources and to stand as optional AC power memory.

On the vehicle side, the protected arrangement of the charging contacts is preferably adapted stoneware floor at the vehicle. The arrangement of integrated power outlets front or rear of the vehicle to the herein described automated loading contacting provides inexpensive solutions, but strongly intervenes in the vehicle design.

The arrangement according to the invention is particularly suitable for use in the method described below and devices. The invention is explained in more detail below in one embodiment and with reference to the accompanying drawings. Show it:

In Fig. 4 there is shown an example of how a load contact may be made by means of an inventive arrangement. The road vehicle has a current memory and thus functionally connected contact. The vehicle contact is disposed at the bottom of the road vehicle. is located on the ground a positioning aid with an easily passing over a wheel stop threshold and which are mounted so that the road vehicle can be fixed in a desired position. The contact of the external power source is attached so that a charging contact may be made between the contact of the road vehicle in the fixed position and the contact of the external power source. The charging process can be initiated, for example, by a command of the driver or automatically by a command of the road vehicle. In FIG. 5, by way of example various embodiments are shown of appropriate contacts of the arrangement according to the invention. The contacts may be configured such that they are placed on demand into a position that allows the formation of a charging contact. This can be achieved, for example by folding and / or unfolding. Preferably, at least one of the contacts is spring to dampen an impact of the two contacts to one another in the formation of the charge contact and thus avoid damage to the assembly. In Fig. 6 there is shown by way of example, as a positioning aid can be arranged with a device for initiating the formation of a charging contact. The information to be propelled in the direction of travel threshold is connected to a switch which is triggered when a wheel of the road vehicle has reached the fixed position. the initiation and interruption of a charging process can be controlled by such a switch. Between the over-propelled threshold and the fixing wheel stop is a lever mechanism, which, triggered by the reaching of the fixed position by a wheel of a road vehicle, ensures that contact is brought into a position which allows the formation of a charging contact. Fig. 7 shows an example of how the contacts can be configured together with a leading guide. In each case, a contact and a part of the guide can be structurally connected to one another in the form of a plug or a mating connector. but the contacts and the leading guiding the arrangement of the invention can not be arranged directly to each other in a common device independently of each other, structurally.
