This application provides a powertrain, a control method for a motor controller, and an electric vehicle. The powertrain includes a motor controller and a drive motor, the motor controller includes three bridge arms connected in parallel, each bridge arm includes an upper bridge arm switching transistor and a lower bridge arm switching transistor, one end of each bridge arm is configured to connect one end of a direct current power supply and one end of a power battery, the other end is configured to connect to the other end of the power battery, bridge arm midpoints of the three bridge arms are configured to connect to three phase windings of the drive motor, and a bridge arm midpoint of one of the three bridge arms is configured to connect to the other end of the direct current power supply. In response to that the direct current power supply switches from outputting a direct current to stopping outputting the direct current, an upper bridge arm switching transistor of one bridge arm of the other two bridge arms of the three bridge arms is turned on and a lower bridge arm switching transistor of the other bridge arm of the other two bridge arms is turned on. The power battery is configured to supply power to one phase winding and another phase winding, to reduce slipping sound and improve an NVH feature of the electric vehicle.
