The invention provides a heat pump system of an electric automobile, the electric automobile and a heat control method of the electric automobile. The heat pump system comprises a battery passenger compartment integrated heat pump loop, a battery refrigerating loop, a battery cooling loop, a motor cooling loop and a passenger compartment warm air loop, and the battery passenger compartment integrated heat pump loop and the battery refrigerating loop refrigerate the battery cooling loop through a first battery cooler and a second battery cooler correspondingly. The battery passenger compartment integrated heat pump loop heats the passenger compartment warm air loop through a water-cooled condenser; the passenger compartment warm air loop is connected into the motor cooling loop through a four-way valve, and the battery cooling loop is connected into the motor cooling loop through a five-way valve. The system is a double-compressor indirect type heat pump system, is compact in structure, high in reliability, high in high-temperature refrigerating capacity and low in low-temperature heating energy consumption, and heats a passenger compartment in winter by utilizing motor blockage heat transfer, so that the cost of the whole vehicle is reduced, and the driving range of the electric vehicle in winter is increased.
