This application provides a motor locked-rotor torque control method, a motor locked-rotor torque control apparatus, and an electric vehicle. The motor includes a first phase stator winding, a second phase stator winding, and a third phase stator winding, and when the motor is in a charging mode, the first phase stator winding and the second phase stator winding are connected in parallel, and then are connected to the third phase stator winding. The method includes: obtaining a current rotor magnetic field angle of the motor when the motor is in the charging mode; determining a target stator magnetic field angle of the motor based on the current rotor magnetic field angle and a preset mapping relationship between a stator and rotor magnetic field included angle and a locked-rotor torque; and further, controlling a first phase current of the first phase stator winding and a second phase current of the second phase stator winding, so that a stator magnetic field angle of the motor is the target stator magnetic field angle. According to this application, it can be ensured that the stator magnetic field angle of the motor is minimized when the motor is in the charging mode, so that safety during charging is improved and applicability is strong.
