description The invention relates to an air pressure monitoring system and device for monitoring a thermal event of a power battery pack of an electric vehicle. The air pressure monitoring system comprises a controller unit, a pressure detection unit, a power supply conversion unit, a data interface unit and an abnormal state monitoring unit, the pressure detection unit, the data interface unit and the abnormal state monitoring unit are respectively in electrical connection and data communication with the controller unit, the controller unit receives monitoring data from the pressure detection unit, the monitoring data is forwarded to the data interface unit after being processed, and the data interface unit interacts with a vehicle machine system. According to the air pressure detection principle, the air pressure change speed in the battery pack in the power battery module is monitored in real time, so that the thermal event of the power battery is monitored. The detection precision is high, the speed is high, the dete
