Overview of the thermal management system of new energy vehicles

With the popularization of new energy vehicles, their Cruising range and thermal safety in extreme climates have increasingly become the focus of attention. To meet these challenges, thermal management technology has become the key to ensuring vehicle performance and safety. The thermal management of new energy vehicles includes cockpit heating in winter, cockpit cooling in summer, battery cooling and heating, motor heat dissipation and power electronic components heat dissipation. By analyzing the advantages and disadvantages of different thermal management schemes, this paper puts forward optimization suggestions to ensure that each functional module operates within the optimal temperature range, so as to improve the power economy of the vehicle and ensure the safety and stability of the vehicle. This study has important reference value for the development of thermal management technology for new energy vehicles.
