The working principle of the new energy lithium battery automatic fire extinguishing device, when the lithium-ion battery or capacitor internal short-circuit, thermal runaway, high temperature, extrusion by external force, puncture and so on, it is easy to cause the thermal expansion of the battery or capacitor and cause combustion.

When the data of ion particles released by thermal expansion of the battery or capacitor in the capacitor box and abnormal temperature rise data are collected by the fire early detection and early warning system of the fire extinguishing device, the early fire situation is analyzed and calculated through the intelligent control and management system. When the data reaches the early fire warning information, the system will send an alarm signal to the driving area in time for the driver to determine and When the fault area has developed from the early fire to the fire, the intelligent control management system will automatically start the fire extinguishing device host to extinguish the fire. At the same time, sound and light fire alarm signals are sent to the driving area.
