The invention provides a thermal management system of an extended-range electric vehicle, and belongs to the technical field of new energy vehicles. The heat management system comprises a main expansion box, a water heat exchanger, a battery cooler, a first electronic water pump, a second electronic water pump and a four-way valve, wherein the water heat exchanger, the battery cooler, the first electronic water pump, the second electronic water pump and the four-way valve are all connected to a shell of the main expansion box; a first expansion cavity and a second expansion cavity which are mutually independent are formed in the main expansion box, a heat exchange flow channel is formed in a shell of the main expansion box, and the heat exchange flow channel comprises a plurality of sub-flow channels which are mutually independent. According to the invention, the parts required for realizing the thermal management function can be effectively integrated, and the problem of small arrangement space of the forecabin can be obviously improved.
