APPARATUS AND METHOD FOR CHARGING RECHARGEABLE BATTERY

摘要

An apparatus for charging a rechargeable battery includes a voltage detector which detects a voltage between the terminals of a rechargeable battery; a current generator which generates a current for charging the rechargeable battery; and a controller which controls the current generator based on the value of the voltage detected by the voltage detector. Direct current (DC) for charging the rechargeable battery is inputted to the rechargeable battery. A current direction between the terminals of the rechargeable battery is periodically and intermittently inverted in the middle of a charging section where the DC is inputted to the rechargeable battery.
