Energy Saving Potential Analysis of Waste Heat Recovery for Electric Vehicles under Low Temperature Operating Conditions
随着电动汽车的普及,其热管理系统的效率直接影响车辆的能耗和续航里程.本文提出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,证实了通过六通阀控制余热回收条件的策略能够显著降低系统能耗.此外,在-7℃和-18℃环境温度下进行实车测试,配备余热回收系统的测试车辆前1 h能耗分别降低了24%和35%.余热回收系统在验证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%.
Efficiency of the thermal management system directly affects the energy consumption and driving range of a vehicle.This article proposes a new integrated thermal management heat pump system and develops its control strategy.The study analyzed its performance at low temperatures for waste heat recovery.The experiments were conducted under different powers,which verified that the strategy of controlling the waste heat recovery conditions using a six-way valve can reduce the system energy consumption.In addition,in real vehicle tests at-7℃and-18℃,the 1-hour energy consumption of the test vehicles equipped with the waste heat recovery system was reduced by 24%and 35%,respectively.The waste heat recovery system for verifying the energy-saving potential of the application increased the driving range of the electric vehicles by 22.95%under urban conditions and 37.29%under high-speed conditions.
