The invention provides a thermal management system of a pure electric vehicle. The thermal management system comprises a five-way valve, a radiator, a plate heat exchanger and a WPTC heater. A first communication port of the five-way valve is communicated with an electric drive assembly heat dissipation loop, a second communication port of the five-way valve is communicated with a battery heat dissipation loop, a third communication port of the five-way valve is communicated with a battery heating loop, and a fourth communication port of the five-way valve is communicated with a first heat exchange loop of the plate heat exchanger; a first heat exchange loop of the plate heat exchanger is communicated with a vehicle air conditioner system, a second heat exchange loop of the plate heat exchanger is communicated with a vehicle air conditioner system, the first heat exchange loop exchanges heat with the second heat exchange loop, a fifth communication port of the five-way valve is communicated with a radiator, and the radiator is further communicated with the electric drive assembly heat dissipation loop and the battery heat dissipation loop. Through switching control over the five-way valve, the air conditioning system heats the battery, and heat generated by the electric drive assembly and the battery heats the passenger compartment. The energy consumption of the electric automobile can be reduced, and the endurance mileage is increased.
