[0002] With the popularization of electric vehicles, various places have stepped up the construction of charging station facilities to cope with the problem of electric vehicle endurance. During the charging process of electric vehicles, the aging and damage of the battery pack and the internal short circuit of the charging plug may cause the temperature of the car battery pack to rise instantly and catch fire. Due to the small space of the battery, the temperature inside will continue to increase, and the chemical substances decomposed by the battery combustion contain certain oxides. If not controlled in time, an explosion may occur.
