Beschreibung
Zusammenfassung:	A battery assembly includes an enclosure, an outgas sensor within the enclosure, a pressure relief device within the enclosure, a pressure relief sensor within the enclosure, and a processor within the enclosure. The outgas sensor is configured to sense an outgas event of one or more battery cells within the enclosure and output a first sense signal. The pressure relief device is configured to release gas pressure from the enclosure, in response to pressure within the enclosure exceeding a threshold value. The pressure relief sensor is configured to sense a pressure release event caused by the pressure relief device and output a second sense signal. The processor is configured to receive the first sense signal and the second sense signal, and to transmit information associated with the first and second sense signals to a system that is external to the enclosure.
