ABSTRACT:
A method for managing power of a power source and a system is disclosed. The method includes determining (404) a power source capacity value for the power source having a plurality of cells. Further, the method includes determining (406) a cell-capacity value for each cell of the plurality of cells. Furthermore, the method includes determining (408) a duty-cycle ratio value for each cell of the plurality of cells according to the determined cell-capacity value of the cell and the power source capacity value. Moreover, the method includes drawing (410) power from each cell of the plurality of cells according to the determined duty-cycle ratio value of the cell to achieve the power source capacity value for the power source.
