Abstract

A method and apparatus for charging a rechargeable battery in which a constant current is first applied until the rated voltage of the battery is reached, followed by a period during which a reduced current is applied to the battery. The reduced current results in lowering the amount of unwanted heat being dissipated in the charge-current transistor connected to the battery. Finally, a constant voltage is applied to the battery to finish the charging cycle. Reducing the heat dissipation enables the use of smaller less expensive charge-current switch transistors, which for example, are advantageous in applications such as mobile communication devices or other portable electronics assemblies.
