Description

Technical Field

[0001] The utility model relates to the field of fire extinguishing equipment, in particular to a car battery fire extinguishing device. Background Art

[0002] With the requirements of environmental protection and the progress of science and technology, the development of new energy vehicles has been rapid. The sales volume of new energy vehicles has increased year by year, and the number of vehicles in use has continued to increase. However, with the continuous increase in the number of new energy vehicles, the number of spontaneous combustion and fire incidents has gradually increased. After careful analysis, it is mainly the battery problem of new energy vehicles, which has become the main cause of fire. At present, the power batteries used in new energy vehicles mainly include sodium-sulfur batteries, nickel-cadmium batteries, lithium batteries, fuel cells, etc. Among them, lithium-ion batteries have the advantages of large specific capacity, high operating voltage, long cycle life, small size and light weight. At present, they have become the preferred power battery for new energy vehicles. The negative electrode capacity of lithium-ion batteries is insufficient; the water content is too high, which reacts with lithium to overcharge the battery cell, resulting in gas generation; internal battery cell short circuit causes large current discharge, a large amount of heat, and burns the diaphragm; lithium-ion batteries are overcharged, etc., which will cause fire or explosion and many other problems.
