A thermal control system of an electric vehicle is provided. The thermal control system has a composite cooling architecture. The thermal control system is automatically operated in one of three operation modes to adjust a circulation path of a cooling liquid according to the ambient temperature, the power system temperature and the cabinet air temperature. Consequently, the temperature of the power system is stabilized, the performance and the use life of the power system are enhanced, and the power consumption of the air-conditioning system is reduced.
