Characterization of Waste Heat Recovery in Electric Drive System of Battery Electric Passenger Vehicle
摘要
Abstract
Aiming at the problem of how to recover the waste heat of the motor to improve the thermal performance of the passenger cabin,a simulation model of the thermal management system of a battery electric passenger vehicle is constructed by using AMESim software.On this basis,the effects of refrigerant distribution ratio and thermal management system architecture on passenger cabin heating performance are analyzed under the motor waste heat recovery mode.The results show that at a vehicle speed of 60 km/h,the heat generation of the motor can be up to 1 402 W and the heat generation of the motor controller can be up to 427 W.Compared with the no-motor waste heat recovery mode,the total heat absorbed by the thermal management system from the electric drive system and the environment can be increased by 58.69％-100.57％ and the passenger cabin heating power can be increased by 71.36％-100.37％ by distributing the refrigerant rationally.In the motor waste heat recovery mode,the passenger cabin heating power with the parallel architecture was 23.42％ to 27.23％ higher than that with the series architecture.关键词
