The embodiment of the invention relates to the technical field of automobiles, and discloses an electric automobile charging control method and device and a computer readable storage medium. The electric automobile charging control method comprises the steps that firstly, the rotor position of a motor is obtained; then, based on the position of the rotor of the motor, the electrical angle difference between the rotor of the motor and the first phase of the motor is calculated, and the first phase is any one of the three phases of the motor; determining a target rotation angle of a stator magnetic field of the motor based on the electrical angle difference, a charging power curve of the motor and a preset torque attenuation amplitude; and finally, generating a control mode of the motor based on the target rotation angle of the stator magnetic field. According to the technical scheme of the invention, the stator magnetic field of the motor can be rotated to a specific angle, so that the rotation angle of the rotor is utilized to reduce the torque during boost charging, movement and abnormal sound are weakened to an acceptable degree, and the user experience is improved.

    本发明实施例涉及汽车技术领域,公开了一种电动汽车充电控制方法、装置及计算机可读存储介质,该电动汽车充电控制方法包括:首先,获取电机的转子位置;然后,基于所述电机的转子位置,计算所述电机转子与所述电机的第一相的电角度差,所述第一相为所述电机的三相中任一相;并基于所述电角度差、所述电机的充电功率曲线和预设的扭矩衰减幅度,确定所述电机的定子磁场的目标旋转角度;最后,基于所述定子磁场的目标旋转角度,生成所述电机的控制方式。应用本发明的技术方案,能够将电机的定子磁场旋转到特定角度,从而在升压充电时,利用转子可转动角度,降低扭矩,从而将窜动及异响弱化到可接受的程度,改善用户体验。
