The invention discloses an extended-range vehicle battery heating method, device and equipment and a storage medium, and the method comprises the steps: calculating the on-off time of an upper bridge arm and a lower bridge arm of a three-phase insulated gate bipolar transistor based on a direct-axis voltage of a generator controller calculated based on a battery output voltage and a preset quadrature-axis voltage of the generator controller; and based on the on-off time, pulse current is controlled to heat the battery of the range-extended vehicle. According to the invention, the heating rate of the battery can be improved, a rotating air gap magnetic field formed by three-phase current and an eddy current generated between the fixed permanent magnet rotor are greatly reduced, overheating demagnetization of the permanent magnet of the motor rotor caused by the eddy current is avoided, electromagnetic noise can be remarkably reduced, and the safety of a vehicle in the battery heating process is ensured at the same time.

    本发明公开了一种增程式车辆电池加热方法、装置、设备及存储介质,其中该方法包括步骤:基于电池输出电压计算的发电机控制器直轴电压以及预设的发电机控制器交轴电压,计算三相绝缘栅双极晶体管上下桥臂的通断时间;基于所述通断时间,控制脉冲电流以对增程式车辆电池加热。本申请能够提升电池加热速率,极大的减少了三相电流形成的旋转气隙磁场和不动的永磁转子之间产生的涡流,避免出现涡流导致电机转子永磁体过热退磁,并且可以显著减少电磁噪声,同时保证电池加热过程中车辆的安全性。
