摘要
针对电加热给乘员舱取暖会影响纯电动汽车续航里程的问题,搭建了废热回收的热泵系统,回收动力电池和驱动电机产生的废热,并通过GT-suite仿真分析软件进行分析。取暖工况下,采用电池预热要比单电加热热泵,COP(制热能效比)提升20%。采用电池预热、废热回收的热泵系统要比电加热系统的百公里能耗减少29.6%;采用废热回收的热泵系统要比电加热系统的百公里能耗减少6.7%。结果表明,带电池预热的回收型热泵可使乘员舱取暖系统的COP和整车的百公里能耗有显著优化。
Aiming at the problem that heating the passenger cabin will affect the cruising mileage of pure electric vehicles,a heat pump system for waste heat recovery is built to recycle waste heat generated by power batteries and driving motors,and the analysis is carried out by GT-Suite.Under heating condition,the COP(heating capacity power consumption ratio)of battery preheating is 20%higher than that of single electric heating heat pump.The energy consumption of heat pump system with battery preheating and waste heat recovery is 29.6%lower than that of electric heating system per 100 kilometers.The energy consumption of heat pump system with waste heat recovery is 6.7%lower than that of electric heating system.The results show that the recovery heat pump with battery preheating can significantly optimize the COP of the passenger compartment heating system and the energy consumption per 100 kilometers of the whole vehicle.
