Abstract
A battery charging system includes a battery, a charging equipment that charges the battery, a charge switch unit that determines an electrical connection between the battery and the charging equipment, a capacitor electrically connected in parallel between the battery and the charge switch unit, and a controller that determines whether an ignition of a vehicle is turned off or charging of the battery is completed, to determine whether the charge switch unit is fused by comparing a discharge rate of the capacitor and a preset first reference value after the charge switch unit is turned on/off when the ignition is turned off, and to determine whether a high voltage remains at an output terminal of the charging equipment by comparing a voltage of the capacitor and a preset second reference value after the charge switch unit is turned off when the charging is completed.
