This application provides a motor control unit, an electric drive system, a powertrain, and an electric vehicle, and relates to the field of power electronics technologies. A first terminal of a power transmission interface of the motor control unit is connected to a first input terminal of an inverter circuit by using a first direct current switch, and a second terminal of the power transmission interface is connected to a first terminal of a switch circuit. The switch circuit includes three switch branches, where first terminals of the three switch branches are connected to the first terminal of the switch circuit, second terminals of the three switch branches are respectively connected to one-phase output terminals of the inverter circuit, and each switch branch includes a controllable switch. The input terminal of the inverter circuit is connected to a power battery pack by using a second direct current switch. A controller is configured to control the first direct current switch, the second direct current switch, the controllable switch, and the inverter circuit, so that a power supply charges the power battery pack when the power transmission interface is connected to the power supply, and the power battery pack discharges electricity into a load when the power transmission interface is connected to the load. Using the motor control unit reduces a volume and hardware costs, and improves applicability.
