Description

[0001] The invention relates to a charging device for charging an electrically powered vehicle. Corresponding charging devices are basically known from the prior art. For example, it is known that in a parking garage or on another building structure, for example, at least one charging unit of a charging device is arranged, which can be connected to a vehicle to be charged. For this purpose, the charging device is connectable to a power supply structure and, in particular, via this, to a power supply network. The power supply network can supply the charging device with electrical energy, for example, by means of a medium voltage, e.g. in the range from 1 to 50 kV, and / or by means of a low voltage, e.g. in the range from 220 V to 400 V.The electrical energy provided by the power supply structure of the charging device can be transferred to the at least one vehicle for charging a vehicle-mounted energy storage device, either after conversion on the charging device side or without conversion on the charging device side. In order to avoid having to replace the entire charging device in the event of a defect in the charging device, it is customary to construct a charging device in at least two parts, so that it comprises a charging unit and a support unit, wherein the charging unit can be or is fastened to a building structure, for example a building structure such as a building wall, by means of the support unit. If there is a defect in the charging unit, the defective charging unit can be separated from the support unit and replaced with a functioning charging unit. However, in the event of a replacement, it is necessary to have the correct device orTo enable the new charging unit to be properly supplied with electrical energy from the power supply structure and / or the power grid. To this end, defined adjustments and / or settings must be made to the charging unit and / or to a control device that controls the charging unit and / or the control device acting from the power supply structure and / or to a data storage device (in particular a database).

[0002] DE 10 2022 112 710 B3 describes a docking station for connecting a charging control unit to a power supply network, comprising a housing enclosing the components of the docking station with connection contacts arranged in the housing.

[0003] DE 10 2020 128 736 A1 describes a charging device for charging a drive battery of an electric vehicle from an energy source suitable for charging the drive battery, wherein the charging device has at least one connection for connecting to the charging connection of the electric vehicle and at least one connection for connecting to the energy source suitable for charging the drive battery, wherein the charging device is designed to detect a vehicle identification that uniquely identifies the connected electric vehicle.

[0004] WO 2018 / 130336 A1 describes a vehicle charging system comprising a plurality of charging stations for electrically charging vehicles, a control system, a communication network for communication between the control system and other components of the vehicle charging system, and radio elements for establishing wireless communication between the vehicles and the control system. Identification detection units for detecting vehicles to be charged using identification objects assigned to the vehicles are arranged at at least some of the charging stations.

[0005] DE 10 2010 063 712 A1 describes an arrangement for data acquisition.

[0006] The invention is based on the object of providing a charging device for charging an electrically powered vehicle, which, in particular with regard to a simple and rapid procedure, enables the replacement and installation of a charging device component (charging unit). In particular, the replacement and installation of a replacement component of the charging device (e.g., the charging unit or at least one component thereof) should be feasible without the involvement of a specialist.

[0007] The object is achieved by a charging device for charging an electrically powered vehicle according to claim 1. The dependent claims relate to possible embodiments of the charging device. The object is also achieved by a charging device according to claim 8, a carrying unit according to claim 9, and a method according to claim 10. Claim 11 describes a possible embodiment of the method.

[0008] The invention relates to a charging device for charging an electrically powered vehicle, comprising at least one charging device connectable to a power supply structure and a data storage device. Charging an electrically powered vehicle is understood to mean charging and / or discharging the vehicle by means of the charging device. In other words, the charging device (and the vehicle) can be configured to carry out bidirectional charging during charging of the electric vehicle, i.e., to transfer energy from the charging device to the vehicle and / or from the vehicle to the charging device. The charging device can be or can be connected to the power supply structure in an electrically conductive manner via a first connection interface in order to supply the charging device with electrical energy from a supply network.For example, the power supply structure is designed as a medium-voltage and / or low-voltage network or is connected to a medium-voltage and / or low-voltage network in order to supply electrical energy from the medium-voltage and / or low-voltage network via the power supply structure to the charging device via the first connection interface. It is possible for a medium-voltage and / or low voltage to be supplied to the charging device via the power supply network and for this to be transmitted and / or distributed to at least one charging unit, preferably to a plurality of charging units, in a power supply structure, in particular the charging device. In the course of this transmission or distribution of electrical energy to at least one charging unit, in particular to a plurality of charging units, electrical protection of the at least one supply path can be provided via the power supply structure.For this purpose, the power supply structure can have a protection device.

[0009] The charging device is connectable or connected to at least one vehicle to be charged via a second connection interface in order to supply a vehicle-mounted electrical energy storage device with electrical energy. For this purpose, the charging device can comprise a charging cable or be connectable to a charging cable, wherein the charging cable transmits the electrical energy from the charging device to the vehicle. The charging device has a charging unit and a support unit, wherein the charging device, in particular the charging unit of the charging device, is fastened or can be fastened to a building structure by means of the support unit. In other words, the support unit forms a fastening interface in order to fasten the charging device at least mechanically, in particular exclusively, to a building structure. The building structure can, for example, be a pillar to which the charging device is fastened.Alternatively, the building structure may be part of a building, e.g. a residential building, a garage or a parking garage or a multi-storey car park, so that the charging device can be attached to the building.

[0010] The carrying unit has identification information describing the carrying unit, in particular a machine-readable one. The identification information identifies the carrying unit from other carrying units. In other words, at least two carrying units, preferably at least 10 carrying units, particularly preferably all carrying units intended for connection to a loading unit, can have unique identification information, so that they can be distinguished from other carrying units by means of the identification information. For example, the identification information is designed as a unique serial number of the carrying unit or of a component of the carrying unit. Such a unique serial number thus enables carrying units to be distinguished.Preferably, each serial number is assigned only once, so that the serial number provides a temporally stable attribute that enables a unique identification of a carrying unit from a large number of carrying units.

[0011] The identification information arranged or formed on the support unit can be detected or read by a detection means, in particular by a detection means of the loading unit. In other words, the detection means can detect or determine identification information present on the support unit, so that this identification information is available on the loading unit side.

[0012] Furthermore, a data memory has assignment information or such assignment information can be stored in the data memory, wherein the assignment information describes an assignment of the identification information of at least one carrying unit to location information describing a location of the carrying unit and / or to supply information describing at least one power supply property (e.g., electrical protection) of the power supply structure and / or to charging unit information describing a charging unit. Since, in the event of a charging unit being replaced on a carrying unit, the new charging unit can read out identification information on the carrying unit via its detection means, simplified control and / or simplified documentation of events relating to this new charging unit can be carried out.It is therefore advantageous if identification information relating to the carrying unit connected to it is transferred to a new loading unit in a simple and error-preventing manner, so that location and / or supply and / or loading unit information assigned or to be assigned can be assigned to the loading unit on the basis of a data memory, in particular a database, and the identification information recorded by the loading unit. In particular, the identification information of the carrying unit (newly) assigned to it or (newly) connected to it, recorded by the recording means of the new loading unit, can be used to provide the identification information on the loading unit side, and this can lead to location and / or supply information being assigned to the new loading unit by taking the data memory or the database into account.

[0013] Alternatively or additionally, assignment information can be generated which describes an assignment of a carrying unit to the loading unit assigned to this carrying unit or connected to this carrying unit in a supporting manner. Thus, identification information of the carrying unit, in particular uniquely describing the carrying unit, can be assigned to loading unit information, in particular uniquely identifying or describing a loading unit, and can preferably be set out in corresponding assignment information. Since the detection of the identification information can be carried out using the detection means on the loading unit side, in particular automatically, an incorrect assignment of location and / or supply information to a new loading unit can be prevented, since, for example, no mandatory human and / or mandatory expert intervention is required.

[0014] The detection means of the charging unit can be designed, for example, as a sensor, in particular it can be a sensor that detects a current and / or a voltage.

[0015] It is possible for the data storage device to be arranged or configured spatially separate from the charging unit, in particular spatially separate from the charging device. The data storage device is preferably connected to the charging device via a wireless data connection, at least in part, preferably predominantly, and particularly preferably completely, for example a radio transmission takes place using the mobile communications standard LTE or higher. For example, the charging device can comprise a radio module by means of which wireless data transmission can be carried out between the charging unit and the data storage device or a computer device comprising the data storage device. In the data transmission between the charging unit and the data storage device, an internet or intranet can, for example, be interposed or used as a transmission medium.For example, wireless data transmission between the charging unit and the data storage device can also include at least partial use of a wired network. For this purpose, the computing device can comprise a radio module that can establish a unidirectional or bidirectional radio data connection with the radio module on the charging device side, in particular on the charging unit side. The computing device can be designed as a server, for example, or comprise such a server. In a preferred embodiment, the database or data storage device can be located in a cloud and connected to the charging device via the Internet. On the charging device side, data transmission can take place by means of the radio module to a mobile radio station, in particular the nearest one, wherein the mobile radio station is coupled to the Internet and consequently to the cloud or the data storage device.Alternatively or additionally, the computer device and / or the data storage device can be connected or connectable to the charging unit's data acquisition device via a cable for unidirectional or bidirectional data transmission, for example, using an Ethernet or a local area network (LAN). Cable-based data transmission may be appropriate, for example, when using the charging device in an underground car park, as problems can arise there with data transmission, especially exclusively via radio.

[0016] For example, the identification information, which is in particular machine-readable, is embodied in the form of an electronic device, preferably as an electronic circuit, on the support unit. The electronic device can, for example, be embodied as an integrated circuit or integrated into an integrated circuit. For example, the electronic device containing the machine-readable identification information is embodied as a microcontroller (µC), i.e., for example, as an electronic component that has at least the functions of program memory, arithmetic unit, main memory, and registers. It is possible for the electronic circuit to contain a unique serial number of the electronic component.This unique serial number of the component can be used, for example, to distinguish the electronic component from similar electronic components when the component is used in a bus system. According to the invention, the identification system of the electronic component provided for differentiation in a bus system can thus be used to identify the carrying unit containing this electronic component, regardless of whether communication with the electronic component takes place via a bus system. Location and / or supply and / or charging unit information associated with this carrying unit can then be assigned to the identification system of the electronic component.

[0017] The electronic component which contains and / or has the identification information can, for example, comprise at least one integrated circuit, wherein an identification signal having the identification information can be output by energizing the integrated circuit and can be detected or read out by the detection means on the charging unit side.

[0018] It is possible for the identification information, in particular machine-readable, to be transmitted or transferable by means of a contact-based and / or wired information transmission from an identification information memory of the carrying unit containing the identification information to the detection means of the loading unit. In other words, the detection means on the loading unit side detects the identification information without applying a contactless transmission method, for example, without the use of radio technology. Thus, the identification information can be transmitted exclusively via a wired connection from an identification information memory of the carrying unit storing the identification information to the detection means on the loading unit side.In other words, the identification information is transmitted exclusively via contact and / or cable between the carrying unit and the charging unit.

[0019] For example, the carrying unit has at least one temperature sensor unit, wherein the identification information is integrated into the temperature sensor unit. The temperature sensor unit can be designed, for example, as a digital thermometer, in particular a programmable one. For example, the temperature sensor unit is designed such that it can be operated at least temporarily and / or in an optional or sole form of use via exclusively one connection contact and one ground contact. This enables so-called 1-contact operation, so that in order to use the temperature sensor unit, it only needs to be connected to a ground and a single data line strand or a single data line. Optionally, the temperature sensor unit can be configured to enable both 1-contact operation and multi-contact operation. For this purpose, the temperature sensor unit can, in addition to the ground contact and the first data line contact, e.g.at least one or exclusively a single further contact point, in particular a power supply contact. In a first operating scenario, the temperature sensor unit can be operated in 1-contact operation by connecting it exclusively to a ground and a single data line, and in a second operating scenario by connecting it to a ground, to a single data line, and to a power supply line in 2-contact operation. In the case of 1-contact operation, the temperature sensor unit can comprise an electrical energy store which, when the single data line is energized, stores part of the electrical energy transmitted there in order to detect a temperature, in particular at a time offset from the energization, and to output generated temperature detection information via the data line.For example, the electrical energy storage device of the temperature sensor unit is designed as a capacitor. Diverting electrical energy from the data line can also be referred to as power theft.

[0020] The temperature sensor located on the carrying unit side can be used, for example, during normal operation of the charging device to monitor the temperature of a terminal or an interface for electrically connecting the carrying unit to a power supply structure and / or a power supply network and / or a charging device. This allows, for example, a fault involving an elevated temperature to be detected and, if necessary, a timely shutdown of the charging device, in particular the charging unit, to be executed.

[0021] Alternatively or additionally, the temperature sensor unit can have one, in particular a single, data output for outputting temperature information, wherein the identification information can be output via this, in particular the single, data output of the temperature sensor unit. The temperature detected by the temperature sensor unit can be detected by a temperature sensor of the temperature sensor unit and, as a function of this, temperature detection information can be generated. The data output preferably forms a contact-based data output, i.e. no contactless information / signal transmission. The temperature information can be generated, for example, by means of a temperature element of the temperature unit. The temperature detection unit can, for example, comprise a ROM component which preferably contains or comprises the identification information. Alternatively or additionally, in an adjacent orIn addition to the ROM component, the identification information must be stored in the existing memory section or memory element of the temperature sensor unit.

[0022] It is possible for the charging device, in particular the charging unit, to have a radio module for wireless data transmission. For this purpose, the radio module on the charging device side, in particular on the charging unit side, can establish a radio connection with a device spaced apart from the charging device, in particular the charging unit, e.g., a data storage device or a computer device comprising a data storage device, via which radio connection information can be transmitted unidirectionally or bidirectionally. For example, identification information and / or control information controlling the operation of the charging unit and / or operating information describing the operation of the charging unit can be transmitted via the radio module on the charging device side, in particular on the charging unit side. Preferably, the carrying unit does not have a radio module.Alternatively or additionally, it is provided that no transmission of identification information from the carrying unit to the data storage device, in particular to the database, is possible without the charging unit. In other words, the carrying unit can transmit identification information and / or other information to a data storage device, preferably to a data storage device that is spaced apart and / or separate from the charging device, particularly preferably spaced apart and / or separate from the charging unit, in particular exclusively via the charging unit attached to it. The data storage device can be configured, for example, as a database.

[0023] It is possible for the loading unit to have its own data storage device; this data storage device can be provided alternatively or in addition to a data storage device that is spaced apart or separate from the loading unit. At least the carrying device last linked to or assigned to the loading unit or its identification information can be stored in the loading unit's own data storage device. This identification information stored there can be used to compare it with the identification information detected by the detection means on the loading unit. For example, such a comparison can be carried out when the loading unit is started, in particular each time it is restarted. A comparison can, for example, be carried out locally, i.e. without using a data storage device or database that is separate from the loading unit.If the comparison reveals a difference in the identification information, this is an indication that the loading unit has since been mounted on a different carrying unit.

[0024] In addition to the charging device for charging an electrically powered vehicle, the invention also relates to a charging device comprising a charging unit and a carrying unit, wherein the charging device is designed to be used in a charging device described herein for charging an electrically powered vehicle. The invention also relates to a carrying unit comprising identification information describing the carrying unit, in particular identification information integrated into a temperature sensor of the carrying unit and describing the carrying unit, wherein the carrying unit is designed to be used in a charging device described herein for charging an electrically powered vehicle. The invention therefore also comprises a carrying unit and, alternatively or additionally, also a charging unit which, on the basis of the identification information arranged or formed on the carrying unit side,due to the arrangement or design of the detection means on the loading unit side, use in the loading device described herein is possible.

[0025] The invention also relates to a method for operating a charging device described herein for charging an electrically powered vehicle, wherein a database is provided in one method step. This database can include location and / or power supply and / or charging unit information. In a further method step, it is provided that an electrical and / or electronic connection of a charging unit to a carrying unit and a detection of identification information on the carrying unit side and describing the carrying unit takes place by means of a detection means on the charging unit side.Furthermore, an assignment information is generated, wherein the assignment information describes an assignment of the identification information of at least one carrying unit to location information describing a location of the carrying unit and / or to supply information describing at least one power supply property of a power supply structure and / or to charging unit information describing a charging unit.

[0026] In a preferred embodiment of the method, it can be provided, for example, that during normal operation of the charging device, temperature information detected by a temperature sensor arranged on the carrying unit is transmitted from the carrying unit to the charging unit via a data connection interface, and the identification information is transmitted via the same data connection interface. Thus, both temperature information and identification information can be transmitted from the carrying unit to the charging unit via the same data connection interface.

[0027] All advantages, details, embodiments and / or features of the charging device according to the invention for charging an electrically driven vehicle are to be applied to the charging device according to the invention, in particular to the charging unit according to the invention, and to the carrying unit according to the invention as well as to the method according to the invention and vice versa.

[0028] The invention is explained in more detail using exemplary embodiments in the drawings. In the drawings: Fig. 1 a schematic exploded view of a loading unit and a carrying unit according to an embodiment; Fig. 2 a schematic exploded view of a support unit according to an embodiment; Fig. 3 a schematic diagram of a charging device according to an embodiment.

[0029] The charging device 1 shown is used to charge an electrically powered vehicle 50 and comprises at least one charging device 3 connectable to a power supply structure 2, as well as a data storage device 4. The charging device 3 is electrically conductively connectable or connected to the power supply structure 2 via a first connection interface 5 in order to supply the charging device 3 with electrical energy from a supply network 7. In this case, the supply network 7 can represent a higher-level supply network 7, which initially provides electrical energy to a power supply structure 2 via a connection interface 6, and wherein, starting from the power supply structure 2, a supply of several, in particular similar or identically constructed, charging devices 3, 3' can be carried out via corresponding connection interfaces 5, 5'.The charging device 3, in particular a charging unit 9 of a charging device 3, can be connected to an electrical energy storage device 51 of an electrically driven vehicle 5 to be charged via a connection interface 8.

[0030] A connection interface 5, 5', 6, 8 can have interface engagement elements and interface counter-elements that are or can be connected to one another via a connection. For example, interface engagement elements and interface counter-elements are designed as plug-socket connections, wherein a connection can be implemented by means of at least one busbar and / or a connecting cable. The connection interfaces 5, 5', 6, 8 are preferably designed to be detachable or pluggable for electrically connecting the power supply network 7 to the power supply structure 2 and / or for electrically connecting the power supply structure 2 to at least one charging device 3, preferably to at least one support unit 10 of at least one charging device 3, and / or for electrically connecting a charging device 3 to a vehicle 50.For example, a first charging device 3 and a second charging device 3' can each have a support unit 10 and charging unit 9, in particular of a similar or identical design. Preferably, the support units 10 and charging units 9 of at least two charging devices 3, 3' are designed to be similar and / or identical in such a way that, due to the geometric configuration of the charging devices 3, 3' or their components, a charging unit 9 of a first charging device 3 can be connected, in particular plugged, to a support unit 10 of another charging device 3'.

[0031] Preferably, there is an electrically conductive connection between the power supply structure 2 and a first support unit 10 of the first charging device 3, see connection interface 5, and the power supply structure 2 and a second support unit (not shown) of the second charging device 3', see connection interface 5'.

[0032] The charging device 3, in particular a charging unit 9 of a charging device 3, can be connected or connectable to at least one vehicle 50 to be charged, for example, via a connection interface 8, in order to supply a vehicle-mounted electrical energy storage device 51 with electrical energy. In particular, a connection interface 8 transmitting electrical energy is provided between the charging unit 9 and the vehicle 50 to be charged. For this purpose, the charging unit 9 can, for example, have a suitable charging cable and / or a charging socket for receiving a charging connection for charging the at least one vehicle 50.

[0033] The loading device 3 has a loading unit 9 and a support unit 10, wherein the loading unit 9 is fastened or can be fastened to a building structure 11 by means of the support unit 10. For example, the support unit 10 and the building structure 11 are connected to one another in a force-fitting and / or form-fitting and / or material-fitting manner by means of a mechanical connection interface 23. The mechanical connection interface 23 for the load-bearing connection of the support unit 10 and the building structure 11 can preferably be designed as a separate connection to the connection interface 5. For example, the support unit 10 is connected to the building structure 11 by means of a screw connection. The building structure 11 can, for example, represent a column or form part of a building. It is possible for the loading unit 9 to be supported on a building structure 11 exclusively via the support unit 10.In other words, the loading unit 9 can be fastened or attachable to a building structure 11 exclusively via its contact or via its mechanical connection with the support unit 10, in particular firmly.

[0034] The carrying unit 10 comprises identification information 12 describing the carrying unit 10, in particular a machine-readable piece of identification information, which can be detected or read by a detection means 14, in particular by a detection means 14 of the charging unit 9. For this purpose, the carrying unit 10 can comprise an electrical or electronic identification information memory 17 in which the identification information 12 is stored. By means of the detection means 14, the identification information memory 17 can be read out and / or an identification signal generated from the identification information memory 17, which is transmitted to the detection means 14, can be read by the detection means 14.

[0035] In the data memory 4, an assignment information 13 is present or can be stored there, wherein the assignment information 13 describes an assignment of the identification information 12 of at least one carrying unit 10 to location information describing a location of the carrying unit 10 and / or to supply information describing at least one power supply property of the power supply structure 2 and / or to charging unit information describing a charging unit 9.In other words, the data storage device 4 can be used to assign location information and / or supply information and / or charging unit information to a plurality of support units 10 installed at different locations, so that, after identifying the support unit 10 based on the identification information, predefined location information and / or predefined supply information and / or predefined charging unit information can be assigned to a support unit 10 and, in particular, to a charging unit 9 assigned to a specific support unit 10. For example, the supply information can include information about the, in particular, maximum possible, electrical supply power at a specific location or at a specific node of a supply infrastructure.

[0036] In particular, by replacing a first charging unit 9 with a second charging unit 9 on a carrying unit 10 by identifying this carrying unit 10 and thus its performance data or supply data assigned to this carrying unit 10 within the power supply structure 2 (e.g., values ​​of the electrical protection of the node or connection point of the carrying unit 10 within the power supply structure 2), a simplified and / or automated, in particular control-dependent, installation of the new charging unit 9 on the carrying unit 10 can be carried out. The detection means 14 can, for example, be designed as a sensor. In particular, the detection means 14 can detect the identification information 12 by optical recognition and / or by analysis of an electrical or electronic signal.

[0037] The data storage device 4 can preferably be arranged or configured spatially separate from the charging unit 9, in particular spatially separate from the charging device 3. For example, the data storage device 4 is connected to the charging device 3, in particular to the charging unit 9, via a wireless data connection 15. A wireless data connection 15 between the charging device 3 and the data storage device 4 can, for example, be established by a data-transmitting connection between two radio modules 20, 22. For example, a first radio module 20 can be assigned to the charging device 3, in particular to the charging unit 9, and a further radio module 22 can be assigned to the data storage device 4. The data storage device 4 can, for example, be a component of a separate computer device 23 that is spatially separate or spaced apart from the charging device 3, in particular from the charging unit 9. The computer device 23 can, for example,be designed as a server and / or represent a higher-level computer network which serves for the power or energy supply management of a charging device 1 comprising several charging devices 3, 3'.

[0038] The identification information 12, which is in particular machine-readable, can be embodied, for example, in the form of an electronic device 16, preferably as an electronic circuit, on the carrying unit 10. Alternatively or additionally, the identification information 12, which is in particular machine-readable, can be transmitted or transferred by means of a contact-based and / or wired information transmission from an identification information memory 17 of the carrying unit 10 containing the identification information 12 to the detection means 14 of the charging unit 9. Thus, for example, it is possible for the charging unit-side detection means 14 to read or capture the identification information 12 without using a contactless transmission method or without radio.In other words, the detection means 14 can detect identification information 12 held on the carrying unit side, in particular stored there, exclusively in a contact-based and / or exclusively wired manner.

[0039] The support unit 10 can, for example, comprise at least one temperature sensor unit 18, wherein the identification information 12 is integrated into the temperature sensor unit 18. For example, the temperature sensor unit 18 is designed as an electrical or electronic component, e.g., as an integrated circuit, wherein a memory module of the temperature sensor unit 18 functions as an identification information memory 17. In particular, the temperature sensor unit 18 can be equipped with unique identification information 12, which serves, e.g., to identify the support unit 10 assigned to this temperature sensor unit 18. Preferably, the temperature sensor unit 18 is permanently attached to (in or on) the support unit 10, in particular, cannot be removed without destruction. Alternatively or additionally, the temperature sensor unit 18 is not attached to the support unit 10 in a way that can be removed without tools.

[0040] It is possible for a mobile terminal 40 to manually generate and / or change and / or add assignment information 13 and / or identification information and / or location information, preferably relating to at least one carrying unit 10, particularly preferably to specifically individual carrying units 10 of a group of carrying units 10. In other words, a mobile terminal 40, particularly during initial installation of a carrying unit 10, can store identification information 12 describing this carrying unit 10 and / or other information to be assigned to the identification information 12 of the carrying unit in the data memory 4. Thus, an initialization of the data memory 4 or of the assignment information 13 of the data memory 4, i.e., an assignment of at least one initial or start value to the carrying unit 10 or a variable representing the carrying unit 10, can take place.The mobile terminal 40 can establish or at least temporarily form a unidirectional and / or bidirectional data connection with the computer device 23 and / or with the data storage device 4 and / or with the charging device 3, in particular with the charging unit 9, via a wired or wireless data connection (e.g. via the wireless data connection 15).

[0041] Alternatively or additionally, it can be provided that, in addition to machine-readable identification information 12, human-readable identification information 12 is arranged or formed on (i.e. in and / or on) the charging device 3, in particular on (i.e. in and / or on) the charging unit 9 and / or on the carrying unit 10.
