The invention discloses an integrated heat pump heat management system for a pure electric vehicle. The integrated heat pump heat management system comprises a refrigerant loop and a cooling liquid loop which are used for cooling, heating or preserving heat of a battery module of the pure electric vehicle; the refrigerant loop comprises a compressor, a cabin external heat exchanger, a cabin internal heat exchanger, a first PTC heater, an ejector, a gas-liquid separator, a chiller heat exchanger and a direct cooling plate mounted at one end of the battery module; the cooling liquid loop comprises a first water pump, a chiller heat exchanger, a liquid cooling plate installed at the end, away from the direct cooling plate, of the battery module, a motor, an electric control water jacket, a radiator and a second water pump. Refrigerant and cooling liquid double loops are adopted for simultaneous cooling or heating, rapid cooling or heating of the battery module is achieved, the air suction pressure of the compressor is improved through the ejector, and the energy efficiency of the heat pump system at the low temperature is improved.
