Abstract
A battery management system in the form of a gas gauging system is disclosed for enhancing the monitoring of battery power supply. The battery management system includes a battery powered device and a battery selectively connected to the device for supplying operating power to the device. The system also includes an auxiliary power supply configured for connection with the battery for supplying charging power to the battery. A processor is carried by the device and is configured to enable the battery and the power supply, respectively, for powering the device. The processor is further configurable during connection of the auxiliary power supply to completely discharge the battery from a fully charged state to a fully discharged state via a discharge cycle. The system also includes a detector that is configurable to measure battery capacity during the discharge cycle of the battery. Finally, the system includes an output device for outputting a value based upon the measured battery capacity. Additionally, a method of monitoring battery discharge of a battery powered device is disclosed.
