Abstract
A system for a supplemental power source for a hand held portable electronic device is provided. A super capacitor is connected in parallel to a main battery of the portable electronic device. When the main battery becomes disconnected, the super capacitor is used to power the portable electronic device. The super capacitor is also used to provide compensation for the internal impedance of the main battery and the path impedance between the main battery and the load.
