This application provides a method, an apparatus, a system for detecting battery thermal runaway, and a battery management unit. The method for detecting battery thermal runaway includes: obtaining an output signal of an air pressure sensor provided in a battery pack, and obtaining parameter information of the battery pack; determining state information of the air pressure sensor based on the output signal of the air pressure sensor; and generating an alarm signal indicating occurrence of thermal runaway in the battery pack based on the state information of the air pressure sensor and the parameter information of the battery pack. In this application, the thermal runaway detection for the battery pack may be implemented by considering parameter information of both the air pressure sensor and the battery pack, improving the reliability of the thermal runaway detection for the battery pack, reducing the probability of false positives and false negatives, and improving driving safety.
