This application provides a powertrain, a charging control method, and an electric vehicle. The powertrain is disposed between a direct current power supply and a power battery, and includes a motor control unit and a motor. The motor control unit includes three bridge arms and a controller. A first end of the direct current power supply is coupled to one end of each of the three bridge arms and a first end of the power battery. A second end of the power battery is coupled to the other end of each bridge arm. A midpoint of each bridge arm is coupled to one end of a motor winding corresponding to each bridge arm. The other end of each of the three motor windings is coupled to a second end of the direct current power supply. The three bridge arms include a first bridge arm and a second bridge arm. The first bridge arm is turned on or off based on a first PWM signal, and the second bridge arm is turned on or off based on a second PWM signal. The first PWM signal and the second PWM signal are interleaved. When this application is implemented, it can be ensured that heat generated by magnetic steel in the motor falls within a safe range, and a ripple of an output current of the powertrain is reduced.
