The invention provides a battery thermal runaway early warning method and system, electronic equipment and a storage medium. The method comprises the following steps: respectively acquiring a first temperature of a first battery cell and a second temperature of a second battery cell in multiple groups of corresponding battery cells through a temperature sampling loop; monitoring the state of the voltage sampling loop, determining whether the plurality of battery modules meet a corresponding first alarm condition according to the state of the voltage sampling loop, the first temperature and the second temperature, and outputting a thermal runaway alarm signal when the first alarm condition is met; and/or, according to the first temperature and the second temperature, determining whether the plurality of battery modules meet a corresponding second alarm condition, and when the second alarm condition is met, outputting a thermal runaway alarm signal. The accuracy of thermal runaway early warning is improved, the thermal runaway warning signal can be accurately and timely output, and the safety of personnel in a passenger compartment is ensured.
