[0049] An explosion-proof valve 6 is usually provided in the battery 2, and the explosion-proof valve 6 can be provided in the first part 815 or the second part 816 of the box 5. In the case of overpressure or overtemperature inside the battery 2, the explosion-proof valve 6 will open to protect the battery 2. Its main function is to automatically open the valve when there is a risk of explosion or combustion due to the large amount of substances inside the battery 2, and directly dissipate the high-pressure substances inside, thereby preventing the battery 2 from exploding. High-pressure substances usually have a high temperature, and direct discharge will cause greater damage to surrounding equipment or personnel.
