An integrated hybrid electric vehicle central thermal management system

Hybrid vehicles have relatively independent thermal management systems for each device. This results in redundant devices and inefficient use of energy. To reduce device redundancy and reduce energy consumption through energy complementarity, here we report a hybrid vehicle integrated central thermal management system centered on a multimode composite cycle. Subsequently, the composite cycle's dynamic model and experimental test bench are built. Simulation and experimental results show that the composite cycle can operate with good flexibility and stability. By operating in different modes, the composite cycle has the potential to match the temperature, time, and multiple energy flow supply and demand under different operating conditions and seasons. The composite cycle is expected to increase the winter electric range by more than 20%. In addition, it can enhance the engine BTE by 5%. This study proposes and verifies the validity and feasibility of the composite cycle and lays the foundation for its application.
