The battery 3 can represent a single battery or consist of a variety of batteries or battery cells.

The V2X communication interface 4 can be designed as a wireless or wired interface.

The at least one operating parameter of the battery 3 may be a cell voltage and / or a cell current and / or a cell temperature of the battery 3 of the vehicle 10 include. This can change the condition of the battery 3 be determined efficiently. However, it would also be conceivable to have an operating parameter which indicates a state of charge of the body of the vehicle 10 features.
