New energy vehicle fire extinguishing system

In recent years, there have been reports in the media about accidents such as spontaneous combustion and explosion in new energy vehicles using power lithium batteries, which has forced the industry to re-examine the safety of lithium batteries. From the perspective of accident types, the spontaneous combustion of power lithium batteries is usually caused by high temperature, external forces, self aging, overcharging, and other reasons. Due to the fact that power lithium batteries are usually used in combination, once a fire occurs, their diffusion and spread speed is very fast.

The power battery is an energy system, and to maintain normal operation, it will definitely generate heat. To ensure absolute safety, reliable technology must be available from an engineering perspective to ensure that its heating is controllable. There are two basic ways to ensure safety. Firstly, there is a warning in advance, and personnel intervention can be carried out in advance. However, if the warning intervention fails, there must be an automatic and efficient fire extinguishing function.
