The Benefits of Waste Heat Recovery in New Energy Vehicles

Abstract

The rapid development of new energy vehicles (NEVs) has put forward higher requirements for energy utilization efficiency. The installation of a waste heat recovery system (WHRS) in NEVs can enhance their energy utilization efficiency and market competitiveness. This paper systematically analyzes the technical feasibility of waste heat recovery technology in the field of NEVs and the economic benefits it brings. The study shows that the application of waste heat recovery can significantly improve the low temperature performance of NEVs, with the coefficient of performance (COP) increasing by an average of 10% to 20%. It can reduce the dependence on fossil energy, increase the overall performance, mileage, and battery life of the vehicle, and enhance market competitiveness. Future research can focus on the development of small and efficient waste heat recovery devices and intelligent vehicle thermal management technologies to promote large scale application and contribute to the sustainable development of the NEV industry.
