Abstract: The invention relates to a vehicle battery arrangement comprising sensors and an electronic sensor system, by which means the charging and operating state of the vehicle battery is monitored. Said vehicle battery arrangement comprises a heat insulating box (1) provided with a cover (9). The sensors, electronic sensor system and other electronic components for data processing and storage are split between two thermally coupled electronic modules. A first electronic module is connected to the battery in a mechanically fixed manner as a battery module (6), and the second electronic module is connected to the cover (9) of the heat insulating box (1) in a mechanically fixed manner as a cover module (12), the two modules being interconnected for data transmission preferably by means of a power line communication.
