Thermal management system of electric automobile

The invention relates to the technical field of automobile thermal management, in particular to an electric automobile thermal management system which comprises a four-way valve, a compressor, a gas-liquid separator, a temperature control module, a battery pack direct cooling plate and a cab heat exchanger. The gas-liquid separator is connected with the compressor; a third interface of the four-way valve and a fourth interface of the four-way valve form a loop through the temperature control module, the battery pack direct cooling plate and the cab heat exchanger; opening and closing of the four-way valve and the valve mechanism are controlled, so that temperature control is conducted on the battery pack direct cooling plate and the cab heat exchanger through different cab management modes and different battery pack heat management modes. According to the thermal management system of the electric automobile, the thermal management requirements of the cab and the battery pack can be met, the refrigerating or h
