The invention discloses a heat pump system of a pure electric light truck. The heat pump system comprises a refrigerant system loop and a water side system loop, the refrigerant system loop comprises a compressor, a condenser outside a vehicle, a condenser inside the vehicle, an evaporator inside the vehicle, a gas-liquid separator and a plate heat exchanger; the compressor is connected with the external condenser, the external condenser is connected with the internal evaporator, the internal evaporator is connected with the gas-liquid separator, and the gas-liquid separator is connected with the compressor; the water side system loop comprises a motor water pump, a four-way water valve, a battery water pump, a water PTC (Positive Temperature Coefficient), a three-way water valve, a battery, a motor and a plate heat exchanger; the plate heat exchanger is connected with a four-way water valve, the four-way water valve is connected with a battery water pump, the battery water pump is connected with a water PTC, the water PTC is connected with a three-way water valve, the three-way water valve is connected with a battery, and the battery is connected with the plate heat exchanger. Compared with an air heating PTC heating mode, the energy efficiency ratio is remarkably increased, the power consumption of the whole vehicle in winter is greatly reduced, and the endurance mileage of the vehicle is increased.
