Abstract
A battery management system for a high-voltage battery of a motor vehicle monitors battery cells of the high-voltage battery. The battery management system can be arranged in a battery housing of the high-voltage battery and has an electronic circuit which is arranged on a circuit carrier and has a processor and a communication interface for communication with at least one vehicle-side unit external to the high-voltage battery. The electronic circuit has at least one pressure sensor, which is designed to detect pressure signals in the battery housing and transmit same to the processor. The processor is designed to detect, on the basis of the transmitted pressure signals, a thermal runaway of at least one battery cell of the high-voltage battery, to generate a signal in the event that a thermal runaway is detected, and to provide the signal of the communication interface for transmission to the unit.
