摘　　要：高温工况下电动汽车不仅要满足乘员舱的降温需求,还要保证电机、电池、CDU和MCU等部件的冷却需求,部件繁多导致电动汽车冷却系统架构十分复杂。本文以乘员舱降温能力和压缩机功率为评价指标,针对驻车、驻车充电、匀速行驶和爬坡行驶等4种典型工况,采用系统仿真方法探究水冷冷凝器与电机系统串联/并联冷却系统两种架构的性能差异,并基于分析结果提出串联/并联切换式冷却系统和半并联式冷却系统两种新方案,分析结果将为电动汽车热管理系统设计工作提供重要参考与指导。In a high temperature environment,electric vehicles not only need to cool the passenger compartment,but also ensure the cooling requirements of components such as motors,batteries,CDUs,and MCUs.There are many components,so the architecture of the electric vehicle cooling system is very complex.In this paper,the cooling capacity of the passenger compartment and the compressor power are used as the evaluation indicators,and the series/parallel connection between the water-cooled condenser and the motor system is explored by the system simulation method for four typical working conditions,such as parking,parking charging,constant speed driving and climbing driving.The performance differences between the two architectures of the cooling system are analyzed,and two new schemes,the series/parallel switching cooling system and the semi-parallel cooling system,are proposed based on the analysis results,which provide important reference and guidance for the design of thermal management systems of the electric vehicles.
