MOTOR-VEHICLE TRACTION BATTERY ARRANGEMENT

A motor-vehicle traction battery arrangement has a plurality of battery modules arranged in a single horizontal plane (XY) in the vehicle floor, an electrical battery management system and a high-voltage busbar that electrically connects all battery modules and the battery management system to each other. The battery management system serves to monitor all battery modules and has, as functional components at least one contactor as well as, for each battery module, a temperature monitor and/or a voltage monitor. The battery management system is formed by at least two battery management sub-modules, each of which includes some of the totality of all functional components and which are arranged at a distance from each other.
