Abstract

A battery pack of a computer system includes a battery having a nominal critical terminal voltage that may not be exceeded without hazardous failure of the battery. The battery pack includes a controller for routing power from an external power source to the battery to recharge the battery. The controller is configured to apply a time profile of charging power to the terminals of the battery. The profile includes time portions when the terminal voltage of the battery exceeds the nominal rated critical terminal voltage. The controller is also configured to control the time profile to prevent hazardous failure of the battery.
