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.
