Description

technical field [0001] Embodiments of the present invention relate to new energy vehicle technologies, and in particular to a thermal management system for electric vehicles. Background technique [0002] Compared with traditional fuel vehicles, electric vehicles have the advantages of zero emission and low noise. With the development of electric vehicles, the auxiliary components of the vehicle thermal management system are gradually increasing, and the proportion of energy consumption consumed by the auxiliary components is also gradually increasing. Under high and low temperature environmental conditions, the energy consumption of the thermal management system will be greatly reduced. Car mileage. [0003] In order to increase the mileage of electric vehicles in high and low temperature environments, it is necessary to integrate the energy consumption of each circuit of the electric vehicle thermal management system, and improve the energy utilization efficiency of the e...
