The present disclosure provides an electric vehicle thermal management system that heats a battery using power electronics heat. An exemplary thermal management system includes, among other things, a heater circuit, a battery circuit, a heat sink circuit, and a power electronics circuit operating within an ethylene glycol system. A first valve is in fluid communication with one or more of the heater circuit, the battery circuit, the heat sink circuit, and the power electronics circuit. A second valve is in fluid communication with one or more of the heater circuit, the battery circuit, the heat sink circuit, and the power electronics circuit. The second valve is fluidly connected to the first valve to provide at least one operating condition in which waste heat from power electronics in the power electronics circuit is used to heat a battery in the battery circuit.

    本公开提供了“使用电力电子器件热量加热电池的电动车辆热管理系统”。一种示例性热管理系统尤其包括在乙二醇系统内操作的加热器回路、电池回路、散热器回路和电力电子器件回路。第一阀与所述加热器回路、所述电池回路、所述散热器回路和所述电力电子器件回路中的一者或多者流体连通。第二阀与所述加热器回路、所述电池回路、所述散热器回路和所述电力电子器件回路中的一者或多者流体连通。所述第二阀流体地连接到所述第一阀以提供至少一个工况,其中来自所述电力电子器件回路中的电力电子器件的废热用于加热所述电池回路中的电池。
