First Claim
1. A charging apparatus comprising:
- a converter configured to, in a charging mode, receive an input alternating current (AC) voltage and convert the input AC voltage into an output direct current (DC) voltage; and
a controller configured to control the converter,wherein the converter includes;
a motor that includes a stator, a rotor, and coils wound on the stator, the coils corresponding to a plurality of phases of the motor;
an additional coil wound on a portion of the stator that corresponds to a phase of the plurality of phases of the motor;
a switching unit connected to the additional coil and configured to, in the charging mode, selectively supply the input AC voltage or rectified voltage based on the input AC voltage to the motor by performing a switching operation; and
an inverter configured to, in a motor operation mode, convert a battery DC voltage from a battery into an output AC voltage by performing a switching operation of three-phase switching elements and drive the motor, and, in the charging mode, convert the input AC voltage or the rectified voltage into the output DC voltage using the additional coil of the motor and the switching unit and supply the output DC voltage to the battery.

Abstract
A charging apparatus and an electric vehicle including the same are disclosed. The charging apparatus includes a converter for, in a charging mode, converting an input alternating current (AC) voltage into a direct current (DC) voltage and a controller for controlling the converter. The converter includes a motor and a switching unit that is connected to an additional coil wound on a stator of one phase of the motor, and that supplies the input AC voltage to the motor by performing a switching operation. The converter also includes an inverter that, in a motor operation mode, converts a DC voltage from a battery into an AC voltage by a switching operation and drives the motor. In the charging mode, the inverter converts the input AC voltage into the DC voltage using the additional coil of the motor and the switching unit and supplies the DC voltage to the battery.
