  "textContent": "The present application relates to the field of energy storage devices, and in particular to a battery pack. The battery pack comprises: two or more battery modules, each of the battery modules comprising a plurality of battery cells which are stacked in sequence, wherein each of the battery cells is provided with an explosion-proof valve; the battery pack further comprising a thermal alarm device and a battery management system, wherein the thermal alarm device is arranged corresponding to the explosion-proof valve; the thermal alarm device and the battery management system are connected to form a circuit; and a break of the circuit can be caused when the explosion-proof valve is exploded. The present application provides the thermal alarm device to correspond to the explosion-proof valve, and when thermal runaway occurs in the battery module, a circuit break is formed between the thermal alarm device and the battery management system, thus the thermal runaway status of the battery pack can be accurately reflected, and the safety of the battery is enhanced.",
