A charging apparatus for an electric vehicle is provided. The apparatus includes an AC power input terminal receiving one AC input power from among single-phase AC power and multi-phase AC power. A power factor corrector having full bridge circuits receives the AC input power through the AC power input terminal. A link capacitor is charged through the power factor corrector. A first switch connects any one of an AC power input line and a neutral line of the AC power input terminal to the power factor corrector and a second switch selectively connects the AC power input terminal to the power factor corrector, or the link capacitor. The power factor corrector and the switch network operate based on a condition of received AC input power. The second switch includes a third switch and a fourth switch that connect each full bridge circuit to a positive battery electrode.

A power cable breaking detection method for a vehicle includes detecting currents of respective phases supplied to a three-phase motor from an inverter through at least a power cable, and a driving speed of the motor, determining whether the respective currents and the driving speed of the motor satisfy power cable breaking detection conditions, determining whether various conditions are satisfied with respect to a cable breaking sensing reference value of a current command performing cable breaking timer counting when the conditions are satisfied, and determining whether a predetermined period has elapsed such that a cable is considered broken when the predetermined period has elapsed.
