The embodiment of the invention provides a battery heating control method and device, electronic equipment and a storage medium. The method comprises the following steps: determining a control period, wherein the control period comprises a plurality of control stages; the switching tube of one of the three-phase bridge arms is controlled in each control stage, so that each phase of winding of the three-phase alternating current motor is alternately discharged, or the switching tubes of two of the three-phase bridge arms are controlled in each control stage, so that each two phases of windings of the three-phase alternating current motor are alternately discharged. By implementing the embodiment, the inductance value of the motor during energy storage can be increased, and the battery pack is heated, so that low-frequency heating is realized, the cost is reduced, and the practicability is improved.

    本申请实施例提供一种电池加热控制方法、装置、电子设备和存储介质;方法包括:确定控制周期,控制周期内包括多个控制阶段;在每个控制阶段控制三相桥臂中的一相桥臂的开关管,使三相交流电机每一相绕组交替放电,或者,在每个控制阶段控制三相桥臂中的两相桥臂的开关管,使三相交流电机每两相绕组交替放电。实施上述实施例,能够增加电机在储能时的电感量,使电池包加热,从而实现低频加热,降低了成本,提高了实用性。
