The invention discloses a pure electric commercial vehicle heat pump air conditioner and battery cooling integrated heat management system which comprises an electric compressor, a drying tank, a condenser, an evaporator, an expansion valve and a four-way reversing valve, the condenser, the drying tank and the evaporator are communicated to form a first circulation unit, the battery condenser is communicated with a plate heat exchanger, and the evaporator is communicated with a second circulation unit. The pressure switch, the electric compressor, the gas-liquid separator and the four-way reversing valve are communicated to form a third circulating unit, and the first circulating unit and the second circulating unit are connected with the third circulating unit in parallel through the four-way reversing valve. According to the air conditioning system, the two condensers share one compressor, and the two condensers are connected with the electric compressor in parallel for air conditioning and battery cooling, so that the air conditioning system can meet the refrigeration requirement of battery cooling under the refrigeration and heating working conditions.
