An electrified vehicle may include: a main battery and an auxiliary battery; a motor system including a dual inverter connected to the main battery and driving a motor depending on a motor driving mode, and a transfer switch for switching between first and second driving modes included in the motor driving mode; and a charging switch connected between the motor system and the auxiliary battery, and configured to form a boost charging path connected from the auxiliary battery to the main battery through the motor system when the first driving mode switches to a charging mode while driving.

A controller for an electrical drive system includes one or more electrical drives, one or more electrical loads, and a switching component configured to connect the one or more electrical drives to the one or more electrical loads in a switching configuration. The controller includes a processing module configured to receive switching data indicative of the switching configuration and analyze the switching data to determine control data for at least one of the electrical drives. The controller further includes an output module configured to output the control data to the at least one electrical drive. The at least one electrical drive is configured to use the control data to supply the electrical load/s, via the switching component, with electrical power.

An automotive vehicle high voltage bus is connected to a power source by a circuit having a main contactor and a precharge contactor. To energize the bus, the precharge contactor is closed and then the main contactor is closed. Upon completion of precharging, the main contactor is opened and energization of the bus is complete.

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, 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.

An electric drive device for driving a vehicle includes a drive unit for rotating drive wheels of the vehicle.
