The invention relates to the technical field of battery electric vehicle thermal management, in particular to a battery electric vehicle thermal management system with an electric driving system for waste heat recovery. Comprising a heat pump air conditioner module, an electric drive module heat management module and a power battery heat management module, the heat pump air conditioner module is located at one end of the electric drive module heat management module, and the power battery heat management module is located at one end of the electric drive module heat management module. According to the pure electric vehicle thermal management system capable of recycling the waste heat of the electric driving system, provided by the invention, from the perspective of recycling available waste heat, PTC heating and waste heat of a driving motor are fully utilized in a low-temperature heating mode of a passenger compartment; during cold start, the power battery is heated by utilizing the waste heat of the PTC and the motor controller, so that the passenger compartment and the power battery rapidly reach the optimal temperature interval; waste heat recycling of a vehicle electric driving system is achieved, and the purposes of reducing heating energy consumption of a pure electric vehicle in winter and improving comfort of a passenger compartment are achieved.

    本发明涉及纯电动汽车整车热管理技术领域,尤其涉及一种带电驱动系统余热回收的纯电动汽车整车热管理系统。包括热泵空调模块、电驱动模块热管理模块和动力电池热管理模块,热泵空调模块位于电驱动模块热管理模块的一端,动力电池热管理模块位于电驱动模块热管理模块的一端。本发明提供的一种带电驱动系统余热回收的纯电动汽车整车热管理系统,通过重复利用可用余热角度出发,在乘员舱低温制热模式时充分利用PTC加热和驱动电机的余热;冷启动时利用PTC和电机控制器余热为动力电池加热,使得乘员舱和动力电池快速达到最佳温度区间;实现车辆电驱动系统的余热循环利用,达到降低冬季纯电动汽车制热能耗和提高乘员舱舒适性的目的。
