APPARATUS WITH A BATTERY MODULE AND CIRCUIT ARRANGEMENT FOR DETECTING CELL EXCHANGE BY UNAUTHORIZED PERSONS

摘要

The invention is based on an apparatus (1) with a battery module (10) consisting of at least one galvanic individual cell (20), and with a tap for a module voltage (UMOD) between a highest potential of the battery module (10) and a reference potential of the battery module (10). The essence of the invention is that the apparatus (1) has a circuit arrangement (30) which is connected to the tap for the module voltage (UMOD) and is set up to output a signal (35) if the module voltage (UMOD) drops to zero.
