A thermal management system for an electric vehicle is provided. The thermal management system includes a refrigerant system, a coolant system, a plurality of thermal loads, and a coolant-refrigerant heat exchanger including an auxiliary heater positioned to heat both refrigerant and coolant in the coolant-refrigerant heat exchanger. The auxiliary heater is sized to vaporize all of the refrigerant passing through the refrigerant flow path. A control system is operatively connected to the coolant-refrigerant heat exchanger, and is programmed to operate the coolant-refrigerant heat exchanger in an auxiliary heating-only mode in which the coolant-refrigerant heat exchanger is not in an auxiliary heating-only mode in which the coolant-refrigerant heat exchanger is not in an auxiliary heating-only mode. An auxiliary heater vaporizes the refrigerant in the refrigerant flow path without any heat input from the coolant in the coolant flow path; and operating the coolant-refrigerant heat exchanger in a heat purge mode in which at least some heat from the coolant in the coolant flow path evaporates the refrigerant in the refrigerant flow path.
提供了一种用于电动车辆的热管理系统。该热管理系统包括制冷剂系统、冷却剂系统、多个热负荷和冷却剂‑制冷剂热交换器,该冷却剂‑制冷剂热交换器包括定位成加热冷却剂‑制冷剂热交换器中的制冷剂和冷却剂两者的辅助加热器。辅助加热器定尺寸成使通过制冷剂流动路径的所有制冷剂蒸发。控制系统操作性地连接至冷却剂‑制冷剂热交换器,并且被编程为:在仅辅助加热模式下操作冷却剂‑制冷剂热交换器,在仅辅助加热模式下,辅助加热器使制冷剂流动路径中的制冷剂在没有来自冷却剂流动路径中的冷却剂的任何热输入的情况下蒸发;以及在热清除模式下操作冷却剂‑制冷剂热交换器,在热清除模式下,来自冷却剂流动路径中的冷却剂的至少一些热使制冷剂流动路径中的制冷剂蒸发。
