The air conditioner has different working modes and different modes for operating the air conditioner panel, and when the air conditioner is powered by a power supply of a battery or a charging pile of the whole vehicle, only a power key of the air conditioner panel is needed to be pressed; when the air conditioner works by adopting the standby power supply, the AC key of the air conditioner panel is required to be pressed, and the power key of the air conditioner panel is pressed.
When the air conditioner panel has a CAN communication function, the whole vehicle has no serious fault, no battery cell voltage is low, no SOC is low, no secondary alarm is given (the whole vehicle system is powered on ready or has a charging signal), when the VCU judges that the conditions are met, the VCU outputs a control signal of a refrigerating air conditioner power supply, a refrigerating air conditioner high-low voltage power supply contactor is closed, the air conditioner panel is powered on by low voltage electricity, and the high voltage electricity of a battery or a charging pile is output to an air conditioner frequency converter; when the VCU judges that the conditions meet one condition at random, the VCU stops outputting the control signal of the power supply of the refrigerating air conditioner, and the air conditioner is powered off at high and low voltage and stops working.
