摘要: 为了改善某纯电动汽车低温制热系统存在能耗的情况,基于某 PTC制热的纯电动 汽车低温热管理结构方案,通过 AMEsim仿真软件建立了液压热管理模型,并用试验数据验证 了模型仿真结果的可靠性。对该低温制热系统的控制策略进行了优化,结构上加入了电机余热 利用模型。通过仿真进一步分析了环境温度、策略方案、行驶工况对系统制热性能和能耗的影 响。仿真结果表明:在 2个 NEDC工况下,优化后的模型能耗降低了 26.2%,提高了系统的经 济性。

Abstract: In order to improve the problem of energy consumption in the low temperature heating system of a pure electric vehicle, through the simulation software AMEsim, this paper builds a hydraulic thermal management model based on the low temperature thermal management structure scheme of a pure electric vehicle heated by PTC heating, and verifies the reliability of the simulation results by the test data. The control strategy of the low temperature heating system is optimized, and a motor waste heat utilization model is added to the structure. The effects of ambient temperature, strategy scheme and driving conditions on the heating performance and energy consumption of the system are further analyzed through simulation. The simulation results show that the energy consumption of the optimized model reduces by 26.2% under two NEDC conditions, which increases the economy of the system.
