(4) When the control device 1 detects that the rising trend of the battery pack temperature is too fast, the control device triggers the fire extinguishing device B, and the fire extinguishing device B releases part of cooling materials to reduce the temperature of the abnormal battery pack although the temperature does not exceed a safe temperature value;
(5) The control device 1 detects the temperature difference between the received temperature signal outside the battery box and the temperature signal a transmitted by the temperature sensor 12 inside the battery box, and once the temperature difference exceeds a preset range, for example, 30 degrees, an early warning signal is sent or the fire extinguishing device 5, 6 is triggered to cool the battery pack inside the battery box, so that the hidden danger of spontaneous combustion of the battery is reduced.
(6) The odor sensor 14 detects abnormal odor (not limited to odor generated by electrolyte leakage) generated by the power battery pack and gives a sensed signal to the control device, and the control device gives an early warning signal and triggers the automatic fire extinguishing device.
