The invention belongs to the field of electric automobiles, and particularly provides an electric automobile and a heat management system thereof. The electric automobile and the heat management system thereof aim to solve the problems that air conditioning systems of existing electric automobiles are high in electricity consumption during heating in winter, and the endurance mileage of the electric automobiles is affected. The heat management system comprises an air conditioning system, a battery heat management system, a motor heat management system, a first heat exchanger provided with a first channel and a second channel which are independent, a second heat exchanger provided with a third channel and a fourth channel which are independent, and control valves. The first channel and thethird channel are connected to a circuit of the air conditioning system in series, and the second channel and the four channel are separately connected to a circuit of the battery heat management system and a circuit of the motor heat management system in series. The control valves can enable the circuit of the battery heat management system and the circuit of the motor heat management system to be connected in series. The heat management system with the structure can absorb waste heat generated by a power battery and a motor so as to reduce electricity consumption of the electric automobile.
Description
technical field [0001] The invention belongs to the field of electric vehicles, and specifically provides an electric vehicle and a thermal management system thereof. Background technique [0002] Pure electric vehicles have the advantages of no fuel consumption and no exhaust, and are recognized and used by more and more users. However, the existing electric vehicles cannot fully meet the needs of all users due to their short cruising range. In order to further extend the cruising range of electric vehicles, it is necessary to comprehensively manage the energy of the electric vehicle, so that the energy of electric vehicles can be used efficiently. [0003] As the auxiliary equipment that consumes the most energy in electric vehicles, the air conditioning system has a significant impact on the cruising range of electric vehicles. Especially in winter when the temperature is low, the air conditioning system needs to provide a large amount of heat for the cockpit (cockpit a...
