Abstract

An apparatus includes a rechargeable battery, a circuitry, and a controller. The circuitry is operable to receive power from a power source and to provide power to the rechargeable battery and to other electrical components of the apparatus. The controller is configured to monitor power requirements of the apparatus. Moreover, the controller is further configured to provide power from the rechargeable battery in addition to power supplied from the power source during a peak power event of the apparatus.

First claim

What is claimed is:
