Research on thermal management system of next-generation hybrid electric vehicle

Abstract

Abstract New energy vehicles play a bigger role under the National VI emission standard and the double-point policy conditions, which is the focus of Original Equipment Manufacturers (OEMs) and consumers due to the advantages of low fuel consumption and long battery life. The front cabin of a hybrid electric vehicle (PHEV) includes the cooling system of the engine, electric motors, controller and condenser, etc. Compared with fuel and pure electric vehicles, the front cabin has a higher heat load, smaller space, and a great influence of the radiators for PHEV, which has more requirements for the cooling module. As people’s requirements for power and comfort continue to increase, the cost and energy consumption of thermal management systems are also rising. Hence, all OEMs have shifted their focus to developing a new generation of thermal management systems. The performance of the new-generation hybrid vehicle thermal management system can meet the performance requirements of the entire vehicle, and it has the advantages of being suitable for platformization, reducing costs, comprehensive utilization of vehicle energy to reduce energy consumption, high radiating efficiency, small front-end module size, and low fan power.
