Abstract
An electrified vehicle includes a motor including a plurality of windings corresponding to each of phases; an inverter including a DC terminal connected to a main battery, and a plurality of legs connected to each end of the windings; a charging switch connected between one electrode of an auxiliary battery and a neutral terminal of the motor; and a controller configured to turn on the charging switch and to apply a DC offset to each of phase currents of the motor having the phases when the charging mode is performed while driving.
Claims17
A vehicle comprising:
- a motor including a plurality of windings corresponding to each of phases;
- an inverter including a DC terminal connected to a main battery, and a plurality of legs connected to each end of the windings;
- a charging switch connected between one electrode of an auxiliary battery and a neutral terminal of the motor;
- and
- a controller configured to turn on the charging switch and to apply a DC offset to each of phase currents of the motor having the phases when a charging mode is performed while driving of the vehicle,
- wherein the motor and the inverter boost a voltage of the auxiliary battery and output boosted voltage to the main battery to charge the main battery, based on the charging mode during the driving of the vehicle being performed.
A method for controlling a vehicle, the method comprising:
- driving, by a controller, a motor including a plurality of windings corresponding to each of phases through an inverter including a plurality of legs and connected to each end of the windings, based on a voltage of a main battery when a motor driving mode is performed;
- changing, by the controller, the motor driving mode to a charging mode while driving of the vehicle by electrically connecting one electrode of an auxiliary battery and a neutral terminal of the motor;
- and
- applying, by the controller, a DC offset to each of phase currents of the motor having the phases when the charging mode during the driving is performed,
- wherein the motor and the inverter boost a voltage of the auxiliary battery and output boosted voltage to the main battery to charge the main battery, based on the charging mode during the driving of the vehicle being performed.
