摘要

随着电动汽车的广泛普及，其热管理系统的效率直接影响车辆的能源消耗和续航里程。本文提出了一种新的集成式热管理热泵系统和配置的控制策略，并深入分析了其在低温环境下余热回收系统的性能。通过设计不同功率的实验并对比制冷性能系数(COP)，证实了通过六通阀控制余热回收条件的策略能显著降低热管理系统的能耗，此外，本文还针对系统进行了实车测试，在-7 ℃和-18 ℃的环境温度下，配备余热回收系统（RWH）的前1h能耗分别降低了24%和35%，显示其在极端低温环境下提升能效的显著效果。验证余热回收系统在实际应用的节能潜力中，电动汽车在城市工况下续航里程提升了22.95%，高速工况下提升了37.29%，这为热管理系统的设计和优化提供了理论和实验依据。

Abstract

Efficiency of their thermal management system directlyaffects the energy consumption and range of the vehicle with the widepopularity of electric vehicles. The new integrated thermal management heatpump system and control strategy for configuration are proposed in this paper

and deeply analyzes its performance in low-temperature environments for wasteheat recovery systems. By designing experiments with different powers andcomparing the coefficient of performance (COP) of refrigeration

it wasconfirmed that the strategy of controlling waste heat recovery conditionsthrough a six-way valve can significantly reduce the energy consumption of thethermal management system. In addition

this article also conducted realvehicle tests on the system

and at ambient temperatures of -7 °C and -18°C

the energy consumption ofthe first hour equipped with a waste heat recovery system (RWH) was reduced by24% and 35%

respectively

demonstrating its significant effect on improvingenergy efficiency in extreme low temperature environments. In verifying theenergy-saving potential of the waste heat recovery system in practicalapplications

the range of electric vehicles increased by 22.95% in urbanconditions and 37.29% in high-speed conditions

providing theoretical and experimentalbasis for the design and optimization of thermal management systems.
