Description

Technical Field

[0001] The present invention relates to a method for performing a charging process for a vehicle and a system for performing a charging process for a vehicle. Background Technology

[0002] To charge a vehicle's battery, it is necessary to place the vehicle at a sufficiently small distance from the charging station so that the battery can be connected to the charging station.

[0003] Document CN 212827962 U describes a control device for charging electric vehicles.

[0004] A vehicle guidance system is known from document CN 102508489 A.

[0005] A method for automatically finding the best wireless charging location is described in document KR 102120255 B1. Summary of the Invention

[0006] In this context, the object of the present invention is to support the driver of the vehicle during the charging process.

[0007] This objective is achieved by a method and system having the features of the independent claims. Implementations of the method and system are derived from the dependent claims and the specification.

[0008] The method according to the invention sets up a charging process, for example, at least a semi-automatic or automatic charging process, for a power battery serving as an energy storage device for an electric vehicle in a charging field. Here, the vehicle has at least one charging port, which is generally accessible from the outside. The charging field has at least one charging station, such as a so-called charging pile. It is stipulated that, generally after the vehicle has traveled towards or entered the charging field, it is located or placed in its current spatial actual pose on the site of the charging field where at least one charging station is arranged. From this point, the actual pose is generally detected by at least one sensor, and it is checked whether the vehicle's current spatial actual pose satisfies the spatial accessibility requirement of at least one charging port of at least one charging station. If the actual pose does not meet the spatial accessibility requirement, then the driver is required to place the vehicle in at least one spatial theoretical pose, which is a theoretical pose suggested to the driver. Here, in the design, it is possible to suggest only one or more theoretical poses to the driver for the selected charging station. Alternatively, if the current actual position satisfies the spatial accessibility requirement, the vehicle is automatically moved from its current spatial actual position to the selected charging station in at least one charging station in the charging field and is automatically placed in the charging position assigned to the selected charging station.

[0009] Once the vehicle is automatically placed or has been placed in a charging position, at least one charging port of the vehicle is automatically or manually connected to at least one charging port of the selected charging station, and a charging process is implemented, wherein electrical energy is transferred from the charging station to the vehicle or its power battery, wherein the power battery is charged.

[0010] In this method, it is possible in the design that, for a selected charging station, only one or more theoretical poses are suggested to the driver. If the vehicle's current and / or corresponding actual pose meets the spatial accessibility requirements, then the vehicle is machine-controlled, e.g., machine-regulated, by at least one computing unit to automatically move toward the charging pose and automatically position itself, i.e., locate itself in the charging pose, and orient or oriented in the charging pose. It is possible that the vehicle is machine-controlled by its own computing unit and at least one computing unit of the charging site, e.g., at least one computing unit of at least one charging station, wherein, for the automatic movement of the vehicle, the two mentioned computing units exchange signals with control commands via a communication system. It is also possible that the vehicle is remotely controlled at least partially or fully automatically by at least one computing unit of the charging site. Alternatively or supplementarily, the vehicle is at least partially or fully automatically controlled by its computing unit and moves at least partially automatically or autonomously, e.g., semi-automatically or semi-autonomously, or fully automatically or autonomously.

[0011] If the vehicle's actual spatial orientation does not meet the set spatial accessibility requirements, and the vehicle can be placed in at least one suggested theoretical orientation based on the driver's request, then the vehicle is moved and / or driven by the driver in a driver-controlled manner, typically in a controlled manner, such as remote control, from the current spatial orientation to a new, updated spatial orientation. Once the vehicle is placed in the correspondingly generated, updated spatial orientation, it is checked whether the generated or new updated spatial orientation corresponds to at least one suggested theoretical orientation or meets the spatial accessibility requirements. To change the actual orientation, the vehicle and / or its movement is controlled by the driver. Meanwhile, in possible design embodiments, it is conceivable that the driver is notified once the reached current actual orientation meets the set accessibility requirements.

[0012] In the design of this method, it is specified that a corresponding position in the set pose includes a spatial location or spatial position, and a spatial orientation or orientation, and / or related thereof. Here, the corresponding actual spatial pose, as the vehicle pose, is related on the one hand to the actual spatial position of the vehicle's position or location on the site of the charging field, and on the other hand to the current actual spatial orientation or spatial orientation, and therefore to the corresponding orientation or orientation of the vehicle's pose detected by at least one sensor within the charging field. Alternatively or supplementarily, at least one theoretical spatial pose, as the vehicle pose, as needed, is related on the one hand to at least one theoretical spatial position, i.e., at least one corresponding location of the vehicle on the site of the charging field, and on the other hand to at least one theoretical spatial orientation or at least one theoretical spatial orientation, and therefore to the corresponding orientation or orientation of the pose that the vehicle should occupy within the charging field, wherein at least one theoretical pose is proposed and / or predetermined to the driver. The corresponding orientation or orientation of the vehicle, i.e., the actual orientation or theoretical orientation, is generally operated and / or defined according to the vehicle's direction of travel.

[0013] The charging posture, as a vehicle posture, is typically defined by the vehicle's charging position and charging orientation, and further by the orientation or orientation of the vehicle's posture suitable for and / or configured to implement the charging process. Here, the charging posture is spatially assigned to a selected charging station, typically arranged adjacent to it, wherein, when the vehicle is in the charging posture, at least one charging port of the vehicle and at least one charging port of the selected charging station have at most a permissible and / or configured distance between them or each other. In this method, when the vehicle automatically moves from its actual posture satisfying accessibility requirements to the selected charging station, the vehicle not only moves to and is placed in the charging position, but also moves to and is placed in the charging orientation, wherein the vehicle can, for example, be automatically scheduled.

[0014] The design of this method specifies that the corresponding actual pose of the vehicle is the pose in which the vehicle is placed by the driver in a driver-controlled manner and / or machine-controlled manner, and is currently in that pose. At least one theoretical pose is a pose in which the driver can or should place the vehicle so that it can be automatically introduced into a charging pose. If the direct path from the vehicle's actual pose to the theoretical pose contains an obstacle or barrier, then the vehicle can only be placed into and / or moved into the theoretical pose by the driver in a driver-controlled manner, because the vehicle cannot be placed into that pose automatically, i.e., not in a machine-controlled manner. Possible obstacles or barriers are typically objects on the field that the vehicle cannot automatically bypass. At least one obstacle can be fixed in position on the field or moving on the field. A charging pose refers to the vehicle pose that allows the charging process to be implemented when the vehicle is automatically or machine-controlled into that pose from its actual pose. If the driver successfully places the vehicle into the actual pose corresponding to the charging pose, then the charging process can be implemented without further driver-controlled or automatic movement of the vehicle. This situation also arises if the driver is first required to place the vehicle in at least one theoretical pose from the corresponding actual pose, and the vehicle should then be able to be placed in the set charging pose so that the charging process can be carried out without further vehicle movement controlled by the driver or automatically. If the driver successfully places the vehicle in an actual pose that is generally freely accessible or unobstructed and corresponds to the charging pose, then for that actual pose, the accessibility requirement is first checked in the same and / or still checked. However, because the actual pose meets the accessibility requirement, the driver can be informed that further vehicle movement, whether machine-controlled or driver-controlled, is not required to carry out the charging process.

[0015] At least one charging port of the vehicle is disposed at at least one port location on the exterior wall of the vehicle, for example, on the side or left and / or right side wall of the vehicle, or on the rear and / or front of the vehicle. Multiple charging ports may be disposed on the front, rear, or lateral sides of the vehicle. At least one charging port of the vehicle or at least one charging station is designed as a charging socket or charging plug. Here, the location of at least one port of at least one charging port may vary significantly depending on the vehicle type.

[0016] It is specified that the corresponding actual spatial pose of the vehicle, especially its actual spatial orientation, is related to the interface position of at least one charging port of the vehicle. Alternatively or supplementarily, at least one theoretical spatial pose of the vehicle, especially its theoretical spatial orientation, is related to the interface position of at least one charging port of the vehicle and / or the interface position of at least one charging port of at least one charging station. Typically, the spatial orientation of the vehicle at the corresponding position, i.e., the actual position or the theoretical position, i.e., the actual orientation and / or the theoretical orientation, is taken into consideration, and the interface position of at least one charging port on the outer wall of the vehicle is also taken into consideration.

[0017] The regulations stipulate that, depending on the circumstances, the vehicle may also move automatically or semi-automatically to the corresponding actual pose based on at least one proposed theoretical pose, and / or be moved to the corresponding actual pose by the driver or through the driver in a driver-controlled manner, such as by driver regulation or manually, directly via the vehicle's steering wheel or indirectly via remote operation of a terminal device. If and / or once the vehicle is in an actual pose on the site that satisfies accessibility requirements and corresponds to at least one theoretical pose, then the vehicle moves automatically, i.e., controlled by at least one computing unit, such as remotely controlled and / or autonomously, from that theoretical pose and is placed in the charging pose without requiring driver control and / or intervention.

[0018] Furthermore, it is specified that a theoretical pose and / or charging pose are predetermined and / or set according to at least one energy transfer element. Here, at least one energy transfer element is designed, for example, as a charging cable of a specific length, to connect at least one charging port of the vehicle to at least one charging port of at least one charging station, and to exchange electrical energy between at least one charging port of the vehicle and at least one charging port of at least one charging station, wherein typically, the vehicle's power battery is supplied with electrical energy and charged through this energy transfer element.

[0019] It is also possible that at least one charging port of the selected charging station is designed as a transmitter, such as an induction source, and at least one charging port of the vehicle is designed as a receiver for sensing the wireless charging process, wherein when the vehicle is in a charging position, the distance between at least one charging port of the selected charging station and at least one charging port of the vehicle is at most the distance set for this purpose.

[0020] Furthermore, the spatial accessibility requirements for setting up and / or setting up the corresponding actual position of the vehicle are also related to the corresponding locations of at least one energy transfer element and the charging interface on the vehicle and at least one charging station. If such energy transfer element is designed, for example, as a charging cable, then it has a specific maximum length. If the vehicle is positioned in a charging position, then the permissible distance for this setup between at least one charging interface of the vehicle and at least one charging interface of the charging station is at most as long as the length of the charging cable.

[0021] If it is determined that the vehicle's current actual position does not meet the accessibility requirements, then it means that the vehicle cannot automatically reach the set charging position from that actual position.

[0022] As described above, the corresponding actual pose of a vehicle is related to its corresponding actual position. However, it is also possible that a vehicle can have different actual orientations in a given actual pose, which further means that at least one charging port in the same actual position of the vehicle will have different distances from at least one charging port of the selected charging station in different actual orientations. Therefore, at least one charging port of the vehicle in a particular charging position can be facing away from or away from the selected charging station, wherein the distance is greater when facing away from the vehicle's at least one charging port, and smaller when facing the selected charging station's at least one charging port.

[0023] Before the vehicle is positioned on the charging site, it is initially located in an initial position outside the charging area. Furthermore, it is stipulated that if a critical state of charge needs to be determined for the battery, the charging process is initiated by the driver and / or automatically. Here, starting from the vehicle's initial position, one of several charging sites is identified and / or selected, or the location of that charging site is determined and / or selected, and the vehicle and / or its driver is navigated to that charging site. Once the vehicle arrives at the charging site, it is placed in its actual position on the charging site.

[0024] The system design according to the invention is for automatically implementing a charging process for a vehicle, typically in a charging field, wherein the vehicle has at least one charging interface for a power battery, and the charging field has at least one charging station with at least one charging interface. Here, it is specified that the vehicle is already in a spatial actual pose given by its current actual position and / or actual orientation on the site of the charging field. The system includes at least one typically optical sensor—e.g., a camera, at least one computing unit, and at least one output module as components. The at least one sensor is designed to detect, determine, and / or acquire the vehicle's spatial actual pose. Based on the vehicle's thus detected spatial actual pose, at least one computing unit is designed to check whether the vehicle's current spatial actual pose satisfies the spatial accessibility requirement for at least one charging interface of at least one charging station. Here, if at least one computing unit determines that the accessibility requirement is not met, then at least one output module is controlled by at least one computing unit, wherein at least one output module is designed to typically visually—e.g., via text—and / or acoustically instruct the driver to place the vehicle in at least one theoretically proposed spatial pose for this purpose. If, alternatively, at least one computing unit determines that the spatial accessibility requirements for the vehicle's current actual position are met, then at least one computer unit is designed to enable the vehicle to move automatically from its current spatial actual position, for example, to drive and / or be dispatched to a selected charging station among at least one charging stations, and to automatically place the vehicle in a charging position set for this purpose.

[0025] Furthermore, at least one charging port of the vehicle can be connected to at least one charging port of the selected charging station, and the charging process can be implemented. The charging ports of the vehicle and the selected charging station are typically connected manually by the driver via energy transfer elements. However, it is also conceivable that the charging ports can be automatically connected, usually by robots at the charging station and / or system.

[0026] It is possible to implement, and generally fully implement, the method according to the invention using an embodiment of the system according to the invention, wherein the method or its flow is controlled and thus regulated and / or adjusted by at least one computing unit. Using this system, when implementing the method, it is possible to automatically place the vehicle in a charging position configured for this purpose, and automatically activate the charging position or the selected charging station therein.

[0027] The system has at least one radio-assisted or wireless communication system with at least two antennas for exchanging information between at least two components used in embodiments of the method. These components are a vehicle, at least one terminal device for or for a driver, at least one charging station and / or charging field itself. It is also possible that this information for implementing the method may be exchanged or exchanged alternatively or supplementally between two computing units of the system—which are assigned to and / or arranged therein—whereby at least one of the at least two computing units may be designed as at least one computing unit of the system.

[0028] It is possible that the computing unit is integrated into or disposed within the vehicle, and in possible designs, it is also designed for at least partial or full automatic control, i.e., typically regulating the movement of the vehicle, and for example, steering it. It is also possible that the computing unit is disposed in the driver's terminal device, whereby the driver may initiate implementation methods and / or control the vehicle, typically remotely, via the terminal device and / or the computing unit. Furthermore, it is possible that at least one computing unit is assigned to and / or disposed within a charging area and / or at least one charging station, and is designed for controlling, typically remotely, the vehicle.

[0029] The design also specifies that the driver's input device has at least one optical and / or acoustic output module, such as a microphone and / or a display area or monitor. The driver's input device is either designed as a portable mobile input device, such as a smartphone or tablet, for communication and data processing. Alternatively, this output module and / or terminal device may be permanently installed in the vehicle. To move the vehicle to the corresponding actual position, the driver can remotely operate and control the vehicle using a terminal device located outside or inside the vehicle.

[0030] Through a communication system, the aforementioned components or their computing units can communicate with each other and exchange the information necessary for implementing the method. This information may include, for example, information about whether the corresponding actual pose meets the accessibility requirements set for this purpose. Furthermore, it is possible for at least one charging station and / or charging area to suggest at least one theoretical pose as information to the driver's input device. To enable the vehicle to automatically move from an actual pose that meets the accessibility requirements to a charging pose, it is possible for the charging area and / or at least one charging station, and the vehicle—typically its computing unit—to communicate directly with each other, wherein the vehicle moves automatically based on the information exchanged in such direct communication.

[0031] Using a communication system or a corresponding supported communication connection system, information can be exchanged between at least one charging station and / or charging area on one hand and a vehicle and / or terminal device on the other, for services or consultations related to implementing the charging process. The communication connection provided between the respective components using the communication system is typically wireless, for example via the Internet, a central communication point (as a connection point), such as a central server assigned to at least one charging area, or directly between at least one charging station and the vehicle and / or terminal device, for example via the Internet, Bluetooth, or Near Field Communication (NFC). Communication or a communication connection is typically provided between the central communication point and the vehicle and / or terminal device for security reasons, especially IT security reasons. If the connection to the central communication point or corresponding server fails, then direct communication or a communication connection is used between at least one charging station and / or charging area and the vehicle and / or output module.

[0032] Before the vehicle is positioned in its actual location on the site, the design of this method utilizes a system design that pre-selects, determines, identifies, and / or locates charging stations—typically multiple charging sites—as possibilities for implementing the charging process. Here, in the so-called offline scenario, a location service, typically a navigation and / or positioning system (GPS), is used in conjunction with a digital offline map, and different charging sites are stored as charging possibilities in the digital offline map. In the online scenario, a location service, such as a navigation and / or positioning system, is also used in conjunction with a digital online map, and at least one charging site, i.e., one or more charging sites, is stored in the digital online map. Furthermore, it is possible that such an online map is provided to the vehicle and / or terminal equipment via a central communication point, such as a server. To identify charging possibilities, it is possible that the vehicle and / or terminal equipment communicate with at least one charging station and / or charging site via a direct wireless information and / or data connection. In this case, location services can be abandoned because the vehicle and at least one charging station are always some distance apart in possible design scenarios, and this distance enables direct communication when a direct wireless data connection is established or can be established between the vehicle and / or terminal equipment and at least one charging station.

[0033] Various information queries can be performed using the described communication system. Here, it is also possible for vehicles and / or terminal devices to query more information about a charging station and / or charging yard via a central server or alternatively directly from at least one charging station and / or charging yard. This is also possible before a vehicle is positioned on the site of the charging yard and first approaches the charging yard when the vehicle is traveling toward and / or being driven. Here, it is possible to query the number of charging stations and / or charging yards near the vehicle. It is also possible to query the occupancy status of at least one charging station, such as a charging pile, within the charging yard. Here, it can be determined how many charging stations are idle or occupied. It is also possible to query the next available time for at least one charging station, for example, when all charging stations are still occupied initially. Based on such queries, a time point or time period, such as 10 minutes, can be transmitted from the charging yard and / or at least one charging station to the vehicle and / or terminal device, at which time at least one charging station is idle. It is also possible to query the length of the charging cable, which serves as an energy transfer element. It is possible that the charging cable of the charging yard or vehicle is used as an energy transfer element. Furthermore, it is stipulated that, on the one hand, the charging site and / or at least one charging station and on the other hand, the vehicle exchange information about the length of the charging cable to be used, wherein spatial accessibility requirements, theoretical pose and / or charging pose are determined based on the charging cable.

[0034] If the charging cable is located within the vehicle, then, for example, it is possible that information regarding the length of the charging cable and the design of the charging interface—i.e., at least one charging socket and / or charging plug—at the end of the charging cable at at least one charging station or charging facility is provided from the vehicle's start point. This can be achieved manually by inputting the information into the vehicle's terminal equipment, such as the infotainment system, by storing the corresponding factory code information, via a terminal device designed as a smartphone and / or via Near Field Communication (NFC). The charging cable may be located in the vehicle's trunk, which may be designed as, or referred to as, the front trunk or storage compartment. It is also possible that at least one charging station in the vehicle queries information about the vehicle's charging cable.

[0035] It is also possible to query the plug type and / or socket type of at least one charging port at at least one charging station. Additionally, the available charging capacity (in kilowatts) of at least one charging station can be queried. In another design scenario, it is possible to query the licensing and / or payment possibilities for the electrical energy transferred during charging. For typical autonomous vehicles, the location of charging stations on the site can be queried. Alternatively or supplementarily, it is also possible to query a detailed map of the charging site, showing the location of charging stations, such as charging piles.

[0036] Furthermore, it is possible to monitor so-called charging valet services or payment services for the charging process through a communication connection between a vehicle and / or terminal equipment on one side and at least one charging interface or charging site on the other side.

[0037] Using this method and system, it is possible for an electric vehicle, typically an electric motor vehicle, such as an electric vehicle or a hybrid vehicle, to be automatically positioned directly and automatically at, and / or beside, a selected charging station in the designated charging position when the vehicle automatically moves to the charging position.

[0038] For example, the charging process can be initiated via a terminal device. Once the charging process is complete, the vehicle can automatically leave the charging position and can also drive out of the charging station. This method takes into account knowledge about the vehicle, namely the location of at least one charging port, and the design of charging accessories, such as charging cables (as energy transfer elements for the vehicle or charging station). Furthermore, knowledge about the charging station is also considered, namely the site plan and the locations of charging stations, which may or may not be occupied. Additionally, knowledge about charging capacity and the licensing possibilities of at least one charging station is utilized.

[0039] Once the driver of the vehicle reaches the actual position on the charging site that meets the accessibility requirements, he can leave the vehicle. The vehicle can then automatically drive to a selected, available charging station suitable for the charging process and be automatically placed in its assigned charging position, as the path between the actual position and the charging position allows for the corresponding automatic movement of the vehicle. Furthermore, it is possible that the vehicle can also automatically navigate along this path through narrow areas of the site and / or automatically bypass obstacles.

[0040] Of course, the features described above and below can be used not only in the corresponding combinations described, but also in other combinations or individually, without departing from the scope of protection of this invention. Attached Figure Description

[0043] The accompanying drawings are described sequentially and comprehensively. The same reference numerals are assigned to the same parts.

[0054] Input areas 24a and 24b Detailed Implementation

[0055] Figure 1 An example schematic illustration of a charging field shows a site 4, on which multiple charging stations 6, designed here and / or referred to as charging piles, are arranged. Only one of the multiple charging stations is shown here, which has a charging interface 8. In addition, the charging field has a computing unit 16 and multiple sensors 18 for optically detecting the site 4 of the charging field, which are cameras in this case. Only one of these sensors 18 is shown here.

[0056] Here, the computing unit 16 and sensor 18 are also designed as components of an embodiment of the system according to the invention. Other components of this embodiment of the system are the computing unit (not shown further) of the vehicle 10 arranged here on site 4, the output module designed as a display area or display, and the computing unit (not shown further) of the terminal device 20 for the driver of the vehicle 10. It is specified here that the output module, designed as a display area, is designed to be touch-sensitive, wherein two input areas 24a, 24b, which can be manually operated by the driver, are imaged on the display area of ​​the output module.

[0057] A charging process is performed on a power battery (not further shown) of vehicle 10 using an embodiment of the method according to the invention. The power battery of vehicle 10 has at least one battery module, and therefore, in the design, also has multiple battery modules as energy storage for at least one motor used to drive the vehicle. For this vehicle 10, in Figure 1 The direction of travel 14 is indicated by an arrow. On the outer wall of the vehicle 10, a charging port 12 for the power battery is arranged, taking into account the direction of travel 14 on the right outer wall.

[0058] In this implementation of the method, it is first specified that vehicle 10 is located outside site 4 and, consequently, the charging site. Once the battery needs charging due to a low state of charge, the charging process is initiated either automatically by the vehicle 10's computing unit or by the driver through input to their terminal device 20. This implementation of the method assumes the existence of multiple spatially distributed charging sites. Once the charging process is initiated, queries for implementing the charging process are sent by the vehicle 10's computing unit or terminal device 20 to a computing unit (not further shown), such as a server, for all charging sites.

[0059] Taking into account the initial position of vehicle 10 outside site 4, for all charging sites, the computing unit selects one with the minimum distance to the initial position of vehicle 10 and / or the shortest reachable time. Furthermore, vehicle 10 and / or its driver are navigated to site 4 of the selected charging site. Additionally, vehicle 10 is placed in the actual pose shown here on site 4, which is generated based on the actual spatial position of vehicle 10 on site 4 and the actual spatial orientation of vehicle 10 within the charging site, wherein the actual orientation is generated here by the direction of travel 14 and the interface position of the charging interface 12 on the outer wall of vehicle 10. Once vehicle 10 stops and / or is parked in the actual pose, then, in an optional design, the driver is informed via the output module of terminal device 20 whether the Charging Valet Parking (CHAVA) service or payment service is available to them, and whether they need to perform any additional actions before the charging process begins. Here, sensor 18 detects the actual pose of vehicle 10 relative to charging station 6 on site 4. Based on this, the computing unit 16 checks whether the actual pose meets the spatial accessibility requirements.

[0060] If accessibility requirements are met, the driver and any other passengers of vehicle 10 can exit the vehicle. Furthermore, it is possible that the first input area 24a on the display area of ​​terminal device 20 is occupied by the function "Start Charging Station". Once the driver operates and / or manipulates the first input area 24a, vehicle 10 moves from its actual position toward the selected charging station 6 and is placed in a charging position. For this purpose, vehicle 10 is navigated to the charging position of the set charging position via the charging field calculation unit 16 and / or its own calculation unit, and is placed in a spatial charging orientation relative to the charging station 6.

[0061] Alternatively, if, when checking the actual pose, the accessibility requirement is not met by the calculation unit 16, then the output module of the driver's terminal device 20 is activated, and the driver is instructed to move the vehicle 10 from the actual pose to a theoretical pose, wherein a theoretical position on the site 4 and a theoretical orientation of the vehicle 10 relative to the charging station 6 are set or configured for this theoretical pose. In the embodiments of the method presented herein, it is specified that, as Figure 1 As shown, the charging port 12 of vehicle 10 faces away from charging station 6. In this case, it is stipulated that, for the theoretical orientation, the driver should at least steer and / or rotate vehicle 10 and place it in the theoretical orientation, where the charging port 12 of vehicle 10 faces charging station 6 or its charging port 8. After vehicle 10 has moved by the driver taking the theoretical orientation into account, it is checked whether the newly generated actual orientation meets the accessibility requirements. If not, the driver will again be instructed to place vehicle 10 in the theoretical orientation. Once vehicle 10 is placed in the set theoretical orientation by its driver and the new actual orientation meets the accessibility requirements, the vehicle automatically moves from the new actual orientation and is placed in the charging orientation relative to charging station 6.

[0062] It is possible that if there are too many obstacles between the actual position and the charging position on site 4—obstacles that prevent vehicle 10 from autonomously and / or automatically moving to the charging position—then the accessibility requirement for the actual position of vehicle 10 is not met. In another conceivable design of this method, it is possible that at a certain point in time, once vehicle 10 is placed in the actual position by the driver, all charging stations 6 on site 4 of the charging field are occupied by other vehicles. Once one of these charging stations 6 becomes vacant for vehicle 10, then, taking into account the charging position, for the vacant charging station, it is checked whether the accessibility requirement is met from the actual position of vehicle 10. Furthermore, it is conceivable that the driver cannot initially use the charging valet service or payment service for their vehicle 10. In this case, it is necessary for the driver to exchange information with the computing unit 16 via terminal device 20 to support the established charging valet service. It is also possible that the authorization of the charging process and the possibility of payment for the charging process are displayed to the driver via the output module of terminal device 20.

[0063] Once vehicle 10 reaches the designated charging position and / or is positioned there, the display area of ​​terminal device 20 can show the driver instructions for connecting charging interface 8 of charging station 6 to charging interface 12 of vehicle 10 via an energy transfer element designed as a charging cable. The driver can establish a connection within the charging cable itself to transfer electrical energy from charging interface 8 of charging station 6 to charging interface 12 of vehicle 10. Alternatively, the connection between charging interfaces 8 and 12 can be established by a charging robot as an additional component of the charging site and system.

[0064] If the vehicle 10 has multiple charging ports 12 on its outer wall, and the selected charging station 6 also has multiple charging ports 8, then it is possible that a corresponding charging port 12 of the vehicle 10 is connected to a corresponding charging port 8 of the charging station 6 through a corresponding energy transmission element, and the power battery of the vehicle 10 is simultaneously supplied with electrical energy from the charging station 6 through multiple energy transmission elements.

[0065] Once the charging process is complete, the driver can remove the charging cable between charging ports 8 and 12, for which a quick guide is also displayed on the output module. Alternatively, the charging cable can be automatically removed by the charging robot.

[0066] Alternatively, the driver may manipulate the second input area 24b on the display area, which is occupied by the "Leave Charging Station" function. In this case, vehicle 10 automatically moves out of its charging position and is removed, and is further placed in a real position that allows the driver to re-enter vehicle 10 and leave the charging site 4 with vehicle 10. However, if this is not possible, then the driver is required to remove vehicle 10 itself from the charging position. If there are too many obstacles in the path set for vehicle 10 to leave site 4, it is conceivable that these obstacles would prevent the automatic movement of vehicle 10.
