The thermal aerosol fire extinguishing device, the smoke sensor, the water level sensor, and the lightning strike prevention sensor are electrically connected with the compartment control panel respectively.
[0021] Specifically, the essence of fire combustion is "free radical chain reaction": combustible molecules decompose to produce active free radicals such as H・, OH・, and O・ at high temperatures. These free radicals react with each other to release heat, maintaining the combustion cycle. The active components in the aerosol (such as K⁺ ions) will have a "quenching reaction" with the free radicals: K⁺ combines with H・ and OH・ to form stable KOH, KH, and other substances, directly consuming the active radicals required for combustion, breaking the "transfer chain" of the chain reaction, and stopping the combustion in an instant (which is the core reason why the thermal aerosol extinguishing efficiency is much higher than that of traditional dry powder and CO2). When the smoke sensor senses a fire, the thermal aerosol fire extinguishing device generates efficient fire extinguishing aerosol through controllable combustion, extinguishes the fire with a physical suffocation + chemical inhibition dual mechanism, and avoids secondary harm through temperature control design. The water level sensor monitors the water accumulation inside the battery compartment in real time, and through timely warning or linkage protection, it avoids safety accidents such as short circuit, electric shock, and battery damage caused by water accumulation. The lightning strike prevention sensor is linked with the control system of the battery swap cabinet, and when lightning threat or lightning strike is detected, it automatically takes protective measures such as cutting off part of the non-critical circuit power supply or starting the standby protection module, reducing the damage risk of the battery swap cabinet and the internal battery caused by lightning strike, and ensuring the safety of the equipment.

The temperature sensor is arranged in the battery compartment 1034, and the heat dissipation fan is arranged on the inner side wall of the heat dissipation groove of the rear end wall of the battery compartment 1034. The heat dissipation fan and the temperature sensor are electrically connected with the compartment control panel. The temperature inside the battery compartment is monitored in real time by the temperature sensor. When the temperature exceeds the preset threshold, the heat dissipation fan starts to work, quickly discharging excess heat, effectively preventing the temperature inside the battery compartment from rising too fast.
