The invention provides an electric vehicle heat management control method and an electric vehicle, and relates to the technical field of energy. The heat management control method is used for controlling a valve of a refrigerant loop of the electric vehicle to achieve heat supply of the electric vehicle, an inlet of a second valve is used for being connected with an outlet of a compressor and controlling the flow of compressed refrigerant output by the circulating compressor, and an outlet of the second valve is used for being connected with an inlet of the compressor. The heat management control method comprises the steps that an air conditioner starts to supply air under the condition that the air conditioner of the electric vehicle adjusts and increases the hot air volume at the first moment, and the first valve of the refrigerant loop is controlled to reduce the opening degree to a first preset valve opening degree, and controlling a second valve of the refrigerant loop to increase the opening degree to a second preset valve opening degree. In this way, when the external temperature is lower than the critical temperature of heat absorbed by the refrigerant, the heat management system can be controlled to achieve rapid and stable heat supply of the passenger compartment of the electric vehicle without using an electric heater.

    本申请提供一种电动车辆热管理控制方法和电动车辆,涉及能源技术领域。热管理控制方法用于控制电动车辆冷媒回路的阀门实现电动车辆供热,第二阀门的入口用于连接压缩机的出口并控制流通压缩机输出的压缩冷媒流量,第二阀门的出口用于连接压缩机的入口,冷凝器的入口用于通过第一阀门连接压缩机的出口,电动车辆处于低温环境,热管理控制方法包括:在第一时刻电动车辆的空调调节增大热风风量的情况下空调开始出风,控制冷媒回路的第一阀门减小开度到第一预设阀门开度,控制冷媒回路的第二阀门增大开度到第二预设阀门开度。这样在外界温度低于冷媒吸收热量的临界温度时,无需使用电加热器,就能够控制热管理系统实现电动车辆乘员舱的快速稳定供热。
