Description

BRIEF DESCRIPTION OF THE FIGURES

[0031] Additional advantages and embodiments of the disclosure result from the embodiment examples described below and in reference to the drawings. The drawings are diagrammatically representations and show:

[0032] FIG. 1 a first embodiment example of a device according to the disclosure, and

[0033] FIG. 2 an embodiment example of a motor vehicle according to the disclosure, comprising a second embodiment example of a device according to the disclosure.

DETAILED DESCRIPTION

[0034] In FIG. 1, a first embodiment example of a device 1 according to the disclosure is shown. The device 1 here is implemented as an energy storage device, in particular an energy storage device designed for use as traction battery in a motor vehicle. The device 1 comprises multiple components 2 implemented as battery modules which are each arranged in a component accommodation 3 of the device 1, which is implemented as battery module accommodation. The device 1 moreover comprises a common housing 4 and a control unit 5.

[0035] A component control apparatus 6 is associated with each of the components 2 implemented as battery modules. The component control apparatus 6 is designed here as a module control apparatus and is arranged in spatial proximity of the component 2. The component control apparatus 6 and the component 2 are here connected via a plug connection.

[0036] The components 2 each comprise a security device 7 with a memory 8, wherein the security devices 7, in particular the memory 8 of the security devices 7, are each a non-nondestructively separable constituent part of the components 2. Here, the memory 8 and/or additional components of the security device 7 is/are arranged in an interior of the components 2 designed as battery modules, for example, within or between the energy storage cells of the battery modules. Additionally or alternatively, it can in particular be provided that the memory 8 and/or additional components of the security device 7 is/are, for example, welded, glued and/or molded onto additional constituent parts of the component 2. The security devices 7 or the memories 8 of the security devices 7 are arranged in the interior of the component 2 in such a manner that they are not accessible from outside. The attempt to remove the security device 7 and in particular the memory of the security device 7 leads to destruction of the security device 7 or of the memory 8 and/or of the component 2, so that a removal of the security device 7 or of the memory 8 thereof from the component 2 and the installation in another component of substantially identical design, which can be inserted into the component accommodation 3, is not possible.

[0037] In the memory 8, individualization information individually characterizing the component 2 is stored in each case. This individualization information comprises a serial number and/or at least one security parameter relating to a security function of the component 2 and/or at least one calibration parameter relating to a calibration of the component and/or at least one historical information describing a history of the component. The individualization information here enables an individual characterization of the component 2, so that it can be distinguished from other components of identical design.

[0038] The security device 7 is connected to the control unit 5 via a communication connection 9. The communication connection 9 comprises a section, implemented as single-wire connection, between the security device 7 and the component control apparatus 6. The component control apparatus 6 is connected to the central control unit 5 of the device 1 via an additional section of the communication connection 9. A common ground potential of the device 1, for example, the housing 4 of the device 1 and/or the module grounds of the battery modules, forms a return conductor of the communication via the single-wire connection. It is possible that the section of the communication connection 9 between the component control apparatus 6 and the control unit 5 is also implemented as a single-wire connection. Via the communication connection 9 or via the connection between the security device 7 and the component control apparatus 6, the control unit 5 can communicate with the security device 7 and read out the individualization information in the memory 8. The communication between the control unit 5 and the security device 7 here occurs via a secured communication which prevents an unauthorized intervention in the communication from outside in particular during the exchange of a component 2.

[0039] In the control unit 5, acceptability information is moreover stored, which describes the individual components 2 that are acceptable for an operation of the device 1. Based on the individualization information of the individual components 2 and the acceptability information stored in the control unit 5, an exchange of the components 2 can be detected by the control unit 5. In this manner it is possible to detect an unacceptable exchange of the components 2 and thus also an unacceptable exchange of a battery module of the energy storage device. The acceptability information stored in the control unit 5 can in particular be stored in such a manner that it can be changed only under certain conditions, for example, when a security key is known, and/or taught to the components 2 present in the device 1.

[0040] The components 2 are connected to the component control apparatus 6 via a detachable connection, in particular a plug connection. This makes it possible that the components 2 can be exchanged independently of the component control apparatus 6 which is configured to carry out and/or monitor at least one function of the component 2. By means of the component control apparatuses 6 designed as module control apparatuses, for example, individual parameters of the component 2 implemented as battery module can be monitored for an operation of the energy storage device and/or can be transmitted to the control unit 5 via the communication connection 9. For example, by means of the component control apparatus 6, a voltage, a charge state, a temperature or the like of the component 2 can be monitored. By verifying the exchange of the component 2 with the help of the security device 7 introduced into the component 2 as a non-nondestructively separable constituent part of the component 2, it becomes advantageously possible that, in the case of a defect of the component control apparatus 6, it is possible to exchange only said component control apparatus without an exchange of the components 2 also being necessary. In the case of an exchange of a component 2, the exchange of the component control apparatus 6 can also be dispensed with.

[0041] The component control apparatuses 6 are each implemented as an application-specific integrated circuit (ASIC). The memories 8 of the security devices 7 integrated in the components 2 are each implemented as an electrically erasable programmable read-only memory (EEPROM). It is possible that the security devices 7, in addition to the memory 8, moreover comprise other constituent parts, for example, a communication device designed for a communication with the control unit 5.

[0042] The control unit 5 is moreover configured to undertake a measure after detection of a component exchange. Here, it can be provided that, in the case of an exchange of one of the components 2 determined to be acceptable by the control unit 5, the component 2 then newly inserted into the device 1 is monitored with regard to an exchange. In the case of an unauthorized exchange, that is to say the insertion of a component 2 implemented as battery module in the accommodation 3 which does not comprise a memory 8 with individualization information which is considered to be acceptable, it can be provided, for example, that the functioning of the component 2 during operation of the device 1 is suppressed. Additionally or alternatively, it is also possible that the functioning of the entire device 1 designed as energy storage device is suppressed and/or limited. Additionally or alternatively, it is possible that advice is issued by the control unit 5 to an output device (not shown here) connected to the control unit 5 or to an another control apparatus connected to the control unit 5, or the like. It is also possible that information describing the unacceptable exchange is stored in a memory of the control unit 5.

[0043] In FIG. 2, an embodiment example of a motor vehicle 10 according to the disclosure is represented, which comprises a second embodiment example of a device 1 according to the disclosure. The device 1 comprises at least one component 2 designed as headlight, which is inserted into a component accommodation 3 designed as headlight accommodation. The component 2 comprises a security device 7 with a memory 8, wherein the memory 8 or the security device 7 is implemented as a constituent part of the component 2, which cannot be non-nondestructively separated from the component 2. Here, the memory 8 and/or other constituent parts of the security device are arranged in an interior of the component 2 so that they are not accessible from outside. Here the memory 8 and/or other constituent parts of the component 2 are, for example, molded, welded or glued to one another. In this embodiment example, the security device 7 is directly connected via the communication connection 9 implemented as single-wire connection to the control unit 5 designed as headlight control unit. In this case, a common ground potential which in this embodiment example is a body 11 of the motor vehicle 10 forms the return line. By means of the control unit 5, for example, an operation of the component 2 designed as headlight can occur.

[0044] Analogously to the above embodiments, with regard to the first embodiment example of the device 1, the control unit 5 is designed to carry out a method according to the disclosure so that it can detect an unauthorized exchange of the components designed as headlights 2 and take appropriate measures. It is possible that the device 1 comprises additional components 2 designed as headlights and/or other components 2 of the motor vehicle that are each arranged in a component accommodation 3, wherein these components 2 each also comprise a security device 7 with a memory 8, wherein at least the memory 8 is implemented as a non-nondestructively separable constituent part of the component 2.
