A vehicle charging device is provided. The vehicle charging device is connected between an external power source and a vehicle and provides power for vehicle charging. The vehicle charging device includes: a sensing unit sensing whether a current to be provided to the vehicle is in a normal range, a relay unit selectively cutting off a current passing through the sensing unit from being supplied to a vehicle side, a bypass unit connected to the relay unit in parallel and selectively configuring a bypass circuit for the current passing through the sensing unit, and a controller controlling operations of the bypass unit and relay unit according to a current value measured through the sensing unit.
