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 for supplying the input AC voltage to the motor by performing a switching operation. The converter also includes an inverter for, in a motor operation mode, converting a DC voltage from a battery into an AC voltage by performing a switching operation of three-phase switching elements and driving the motor. In the charging mode, the inverter operates switching elements of at least one phase of the three-phase switching elements and converts the voltage received from the motor into a predetermined DC voltage.
