Method and device for heating battery through motor, electronic equipment and medium

The embodiment of the invention provides a method and device for heating a battery through a motor, electronic equipment and a medium, and the method comprises the steps: introducing a preset current into a straight shaft of the motor, and enabling the preset current to be composed of a DC bias current and an AC current; acquiring the current temperature of a rotor permanent magnet of the motor; and adjusting the preset current according to the temperature. Due to the combination of the direct-axis positive direction current and the alternating current, strong heating current can be generated. The temperature of the rotor permanent magnet is obtained, and the preset current is adjusted according to the temperature, so that over-temperature demagnetization of the permanent magnet can be further avoided. 本申请实施例提供通过电机进行电池加热的方法、装置、电子设备和介质，其中，方法包括：在电机的直轴通入预设电流，所述预设电流由直流偏置电流和交流电流组成；获取电机的转子永磁体的当前温度；根据所述温度对所述预设电流进行调节。由于直轴正方向电流和交流电流的组合，可以产生强大的加热电流。通过获取转子永磁体的温度，根据温度对预设电流进行调节，可以进一步避免永磁体过温退磁。
