Until the temperature inside the battery is lower than the temperature preset in the central controller 190, the central controller 190 turns off the fan 170 and the adjusting member 160 of the overhead air conditioner 110 and the air outlet 121 corresponding to the battery air duct 132 according to the real-time temperature signal, and the operation is completed. The battery cools down automatically.

When starting the car in winter, there may also be a problem that the outdoor temperature is too low and the battery is inconvenient to start. When the temperature of the battery is too low, the central controller 190 turns on the overhead air conditioner 110 according to the temperature signal, and the overhead air conditioner 110 generates hot air. The controller 190 also turns on the fan 170 and the adjusting member 160 of the air outlet 121 corresponding to the battery air duct 132 , and closes the adjusting member 160 corresponding to the air outlet duct 133 and the defrosting air duct 131 . The lower hot air enters the battery compartment through the main air duct 120 and the battery air duct 132 to increase the temperature in the battery compartment. Until the temperature inside the battery is higher than the temperature preset in the central controller 190, the central controller 190 shuts down the fan 170 and the adjusting member 160 of the overhead air conditioner 110 and the air outlet 121 corresponding to the battery air duct 132 according to the real-time temperature signal, and the completion is completed. The battery heats up automatically.
