Abstract
A power system of an electric vehicle, a controller, and the electric vehicle. The power system includes two drive motors and two motor control units. The two drive motors are separately in transmission connection with wheels of the electric vehicle through two clutch apparatuses. Windings of the two drive motors and three-phase bridge arms of the two motor control units form two boost circuits. The two boost circuits are configured to charge a power battery of the electric vehicle by performing boost conversion on an output voltage of a charging pile. The two clutch apparatuses are configured to disconnect a connection between a drive motor corresponding to a boost circuit that is in an operating state and a wheel. The power system can reduce shake and noise in a boost charging process of the electric vehicle.
