    [0001] FIELD OF THE INVENTION The present invention relates to a device and method for communicating with a battery cell as well as a battery cell, a battery module, a battery and a battery system. The invention also relates to a vehicle equipped with such a device and to a method. STATE OF THE ART It is foreseeable that in stationary applications, for example wind power plants as well as mobile applications, for example electric vehicles (EV electric vehicles), hybrid vehicles (HEV vehicles) or hybrid vehicles. Rechargeable on terminal (PHEV vehicles) will be used increasingly rechargeable electric energy accumulators (EES accumulators), as a battery system, battery modules such as lithium-ion batteries for example. A battery system comprises a set of battery cells, for example cylindrical or prismatic cells or cells with electrode windings (JR coil cells). The battery cells can be connected in series to output a higher voltage and / or in parallel to increase the maximum electrical current and capacity. This is how the battery cells can be grouped into battery modules or battery units. In applications for driving vehicles it is possible for example to connect in parallel or in series a hundred battery cells (as traction batteries). To make battery systems relatively complex structures are used. The complexity is divided into several levels. To monitor a battery and / or regulate a battery, different mechanisms are distributed at different hierarchical levels, for example: a status monitoring in a cell level, a voltage regulation at a higher level such as a module level, a battery level or system level and / or load balancing (balancing) distributed between several levels. For the management of the battery system, this requires communication, for example between a control device with a control device or a battery management system (BMS system) and the battery cells and / or other facilities such as sensor installations, electronic power installations and switching facilities. Thus, to reduce the cost, the functions are decentralized and local processing facilities such as dedicated integrated circuits (ASICs) are integrated into the battery cells. Thus, there will be different needs depending on the function, including the speed of transmission and the strength of the communication. For communication, it is necessary to wire the components 10 of the battery system. In particular, for high-voltage battery systems, it is necessary to electrically decouple the components. OBJECT OF THE INVENTION The object of the present invention is to develop a device and method of communication with a battery cell for the galvanic decoupling of the components of a battery system. DESCRIPTION AND ADVANTAGES OF THE INVENTION For this purpose, the subject of the invention is a device for communicating with a battery cell, characterized by a communication installation for exchanging data over a wireless link with the computer. battery cell. The invention also relates to a method of communication with a battery cell, characterized in that a communication installation is used to exchange data with the battery cells via a wireless link. The device and the method according to the invention have the advantage of eliminating the electrical and mechanical connections between the battery cells. This makes it possible to detect weak spots or potential faults such as bushings. It also increases security. In addition, the need for galvanic decoupling of the components is reduced. In addition, it simplifies the production and manufacture, for example, mounting, which overall reduces the cost components and manufacturing cost. Advantageously, the communication installation 35 comprises an antenna such as a magnetic antenna or an electric antenna, which simplifies the structure and manufacture of the device and makes it possible to reduce the costs such as the manufacturing costs and the costs. waste treatment costs. This also simplifies the construction of the battery system.
    [0002] Advantageously, the device is an electromagnetic wave identification device (RFID) such as: RFID receiver, RFID transmitter or RFID transmitter or RFID response transmitter (transponder, transponder). Advantageously, the transponder is a passive transponder which receives from the outside, from the field of the device, necessary for the communication and the internal processing of the process which simplifies the power supply in the transponder. Advantageously, the transponder is an active transponder which receives the energy required for communication and processing by the internal process from a power supply, thereby increasing the range of communication. Advantageously, the communication is in near-field communication mode (NFC mode) to reduce development time and / or development cost and manufacturing cost. In addition, it increases the security and / or reliability. Advantageously, the near-field communication is via a wireless link, which simplifies the structure of the device.
