The invention relates to the field of electric vehicle thermal management, and provides an electric vehicle double-shunt thermal management system which comprises a refrigerant loop, a cooling liquid loop and a battery loop, the refrigerant loop is connected with the cooling liquid loop and the battery loop, and the cooling liquid loop is connected with the battery loop; the refrigerant loop comprises a gas-liquid separator, a compressor, a water-cooling condenser, a first stop valve, a first throttling mechanism, a first heat exchange device, a second throttling mechanism, a second heat exchange device, a one-way valve, a second stop valve, a third throttling mechanism and an evaporator. And the refrigerant flowing through the first heat exchange device or/and the evaporator passes through the gas-liquid separator and then returns to the compressor to complete refrigerant circulation. Heat pump heating is achieved, heat is absorbed from air, waste heat is fully utilized, the energy efficiency of the heat management system is improved, and the refrigerant loop can be conveniently configured into different working modes.
