The invention discloses a battery heating control method and device, a controller, an electric vehicle and a medium, the electric vehicle comprises a PTC heater and a heating proportional valve, the battery heating control method of the electric vehicle comprises the steps that firstly, a heating request of a power battery is generated according to the temperature and SOC of the power battery, then the PTC heater is started after the heating request is responded, and the heating proportional valve is started after the PTC heater is started; the method comprises the following steps: heating a power battery by using a PTC heater, controlling the opening degree of a heating proportional valve, heating the power battery by using the PTC heater, determining the heating target temperature of the PTC heater in real time according to the inlet temperature of the power battery and the environment temperature in the heating process of the power battery, and then controlling the heating target temperature determined in real time to adjust the heating power of the PTC heater. Therefore, according to the battery heating control method of the electric vehicle, the heating power utilization rate of the power battery can be increased, energy waste is reduced, meanwhile, the running cost of the vehicle is reduced, and the driving safety is improved.

    本发明公开了一种电池加热控制方法与装置、控制器、电动车辆、介质,其中,电动车辆包括PTC加热器和加热比例阀,电动车辆的电池加热控制方法首先根据动力电池的温度和SOC生成动力电池的加热请求,然后响应该加热请求后启动PTC加热器,再通过控制加热比例阀的开度使PTC加热器对动力电池进行加热,并在对动力电池加热的过程中,还根据动力电池的入口温度和环境温度对PTC加热器的加热目标温度进行实时确定,然后控制实时确定的加热目标温度调节PTC加热器的加热功率。由此,本发明实施例电动车辆的电池加热控制方法能够提高动力电池的加热功率利用率,减少能源浪费,同时降低车辆的运行成本和提高行车安全性。
