A heat pump air conditioner assembly for an electric vehicle and a control method thereof, and an electric vehicle with the heat pump air conditioner assembly for the electric vehicle are provided. The heat pump air conditioner assembly includes a heat pump air conditioning system (10) and a Heating, Ventilation and Air Conditioning (HVAC) box body (20). An in-vehicle heat exchanger (15a, 15b) of the heat pump air conditioning system (10) is located in the HVAC box body (20). An auxiliary heater (24) is also arranged in the HVAC box body (20). The auxiliary heater (24) is located at a leeward side of the in-vehicle heat exchanger (15a, 15b). The heat pump air conditioning system (10) is provided with a defrosting branch connecting with a refrigerant outlet of an external heat exchanger (13) and a suction port of a compressor (11). When the heat pump air conditioning system (10) is in a defrosting mode, the HVAC box body (20) supplies air to the vehicle, the auxiliary heater (24) is turned on, and the defrosting branch is turned on. The vehicle heat pump air conditioner assembly can still transfer heat into the vehicle when the heat pump system is defrosting, ensuring a suitable vehicle interior temperature and improving ride comfort. Moreover, the defrosting branch effectively improves defrosting efficiency.
