Description

technical field [0001] The invention relates to the technical field of safety protection of household appliances, in particular to a charging protection device and method for a lead-acid battery capable of automatically extinguishing fires. Background technique [0002] While electric vehicles bring convenience to everyone, they also bring hidden dangers to traffic safety that cannot be ignored. Statistics show that 80% of electric vehicle fires occur when the battery is charging, and 90% of electric vehicle fires cause casualties because they are placed in the hallway or aisle. [0003] The special hazards of fires caused by electric vehicles are manifested in two points, namely, the temperature of the fire site and toxic smoke. In 3 minutes, the fire temperature reached a thousand degrees; in 30 seconds, the poisonous gas covered the entire room. [0004] Electric vehicle fire casualties generally occur at night, and this time period is often when people are asleep. Even...
