The invention relates to the technical field of electric vehicles, in particular to a thermal management system of a pure electric vehicle and a control method thereof. The battery electric vehicle heat management system comprises a battery heat management loop, a motor cooling loop, an air conditioner loop and a warm air heating loop, the warm air heating loop comprises a fuel oil heater and a water heating heater, and the battery heat management loop comprises a first heat exchanger, a second heat exchanger and a third heat exchanger. The first heat exchanger selectively communicates with the motor cooling loop, the second heat exchanger selectively communicates with the air conditioner loop, and the third heat exchanger selectively communicates with the warm air heating loop. According to the thermal management system for the pure electric vehicle, each management loop can work independently and can work cooperatively, so that the power consumption of a power battery can be effectively reduced, and the endurance mileage of the electric vehicle in high-temperature and low-temperature environments is increased.
