The invention relates to the technical field of vehicle heat management, in particular to a pure electric vehicle heat pump system based on an air supply enthalpy increasing compressor and a heat accumulator. Comprising a gas supplementing and enthalpy increasing compressor, an outlet of the gas supplementing and enthalpy increasing compressor is connected with a second four-way valve through a pipeline, a gas inlet of the gas supplementing and enthalpy increasing compressor is connected with a gas-liquid separator, and the end, away from the gas supplementing and enthalpy increasing compressor, of the gas-liquid separator is connected with a first four-way valve. According to the pure electric vehicle heat pump system based on the air-supplementing enthalpy-increasing compressor and the heat accumulator, the heat accumulator is connected in series in a battery cooling loop, heat generated due to acceleration and braking energy recovery in the running process is achieved by controlling opening and closing of a stop valve, and it is ensured that a battery works in a proper temperature range; the heat accumulator is heated together with heat generated by the battery through heat exchange of cooling liquid and a refrigerant in the battery cooler; therefore, when the vehicle is stopped for a long time and is not charged, enough heat can still be provided for preheating the battery pack when the vehicle is started.
