The present invention relates to an apparatus and method for simply and efficiently charging a battery. The battery-charging apparatus according to the present invention includes: a voltage-measuring unit for measuring the voltage of a battery; a controller for outputting a charging control signal corresponding to an early charging mode in which charging is performed until the voltage of the battery increases to a preset cutoff voltage (Vc), and a later charging mode in which charging is performed while charging power is lowered in stages; and a charging unit for providing the charging power corresponding to the charging control signal to the battery, wherein a point in time point at which the charging power is lowered in stages is associated with a point I time at which the voltage of the battery reaches the cutoff voltage again by the lowered charging power. According to the present invention, a voltage level can be simply and efficiently increased when the battery is fully charged. |
