The invention relates to an efficient heat management system for a pure electric vehicle, which comprises a motor heat exchange loop, a battery heat exchange loop and a PTC (Positive Temperature Coefficient) heating loop, simultaneous or independent heating and variable-flow heating requests are realized through the controllable opening degree of an electronic three-way valve, and water replenishing and air exchange functions of a motor heat exchange system and heat exchange of a battery system are realized. A radiator cooling mode is adopted, the energy consumption of the whole vehicle in a low-temperature environment can be saved, and the endurance mileage is increased; the aim of heating the battery and improving the discharge capacity of the battery is achieved by repeatedly utilizing the heat of the motor, the energy consumption of PTC heating can be saved on the premise of avoiding energy consumption waste, the energy consumption of the whole vehicle is reduced, and the diversified requirements of users are met.
