When the wireless charging is used, the wireless charging coil 106 generates a large amount of heat, and since the wireless charging coil 106 is adjacent to the battery cell 133, the temperature is transferred to the battery cell 133, so that the temperature of the battery cell 133 is increased, the internal resistance is increased, and the charging efficiency is greatly reduced. When the temperature of the wireless charging coil 106 is monitored to exceed the standard (the wireless charging coil 106 is provided with a thermistor), the refrigerating secondary plate 132 is started, and the refrigerating surface of the refrigerating secondary plate 132 can reduce the temperature of the coil substrate 107, so that the temperature of the wireless charging coil 106 is reduced, and the heating value of the wireless charging coil 106 is controlled. The temperature of the heating surface of the cooling secondary fin 132 is transferred to the air intake fin 130, and the air from the outside enters through the air intake hole 109 and passes through the air intake fin 130, so that the high temperature air near the air intake fin 130 is rapidly taken away, thereby improving the heat exchange efficiency of the air intake fin 130.

If the battery cell 133 suddenly increases in temperature during operation or during non-use, the high temperature heats the heat conducting cover 123, the pressure inside the heated heat conducting cover 123 increases, the piston block 134 moves outwards under the condition of pressure, the piston block 134 drives the wedge trigger rod 135 to move, the wedge trigger rod 135 drives the sliding pin 139 to move (the wedge trigger rod 135 and the sliding pin 139 are not contacted at first, but a movement space is left between them, the wedge trigger rod 135 moves to a position contacting the sliding pin 139 only when the temperature increases to a certain value), at this time, the guide slide rod 137 slides on the bow 136, and the spring 138 compresses, so that the electrode contacting the conductive plate 128 and the battery cell 133 is separated, and the power supply is cut off until the temperature decreases.
