New energy automobile power battery thermal runaway processing method and system

The invention provides a new energy automobile power battery thermal runaway processing method and system, and the method comprises the steps that a terminal control unit obtains a periodic thermal runaway signal sent by a battery management system, and when it is detected that the coded value of the periodic thermal runaway signal is changed from 0X0 to 0X1 or 0X2, the terminal control unit generates alarm information, the alarm information is sent to the Internet of Vehicles background service; and after the vehicle networking background service confirms that the thermal runaway event alarm information from the terminal control unit is received, the alarm information is stored, and the alarm information is sent to the user terminal. According to the scheme, the generated alarm information is sent to the Internet of Vehicles background service by detecting that the coded value of the periodic signal sent by the battery management system and received by the terminal control unit is changed, so that the Intern
