Battery thermal runaway refers to a violent reaction in a battery, triggered by certain external conditions (such as puncture, overheating, short circuit, overcharging, etc.), characterized primarily by rapid and massive heat release, and potentially accompanied by other physical or chemical changes (such as short-circuit discharge, combustion, explosion, etc.).

3) Regarding the propagation of thermal runaway in the battery system, environmental conditions, the triggering method and loading state, the battery pack connection method, the battery thermal management method, and the location of the battery initiating the thermal runaway within the power battery system directly affect the thermal runaway propagation process.

This involves developing safety protection and control strategies, and designing high-safety power battery materials, internal structures, packing methods, and battery box structures to promptly detect potential thermal runaway hazards and effectively block or delay its propagation.
