Abstract

A battery charging apparatus for charging a battery which includes a plurality of battery cells connected to each other in series. The battery charging apparatus supplies an electric charge to the battery which is controlled by monitoring the terminal voltage of each of the battery cells. In the alternative, the battery cells may be divided into battery-cell groups. Each group consists of two or more of the battery cells. The electric charge supplied to the battery is controlled by monitoring the terminal voltage of each of the battery-cell groups. The supply of electric charge is terminated upon monitoring a predetermined voltage in the battery cells.
