Embodiment Construction
[0063] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0064] When the temperature sensor in the battery box or the BMS system detects that the surface temperature of the battery exceeds 80±10°C, it is determined that the battery is abnormally heated, and the primary response is triggered. The BMS system will send an electrical signal to the main controller, which will then send the signal to each fractional controller and pumps via the CAN bus. Since all electromagnetic one-way valves are designed to be normally open, at this time, except for the sub-controller in the battery box where the abnormal temperature rise occurs, the other sub-controllers will receive the signal from the main controller, and close the solenoid valve after action. , to prevent the fire extinguishing agent from being released to other battery boxes causing unnecessary losses and reducing cooling efficiency.
