Abstract
A system and method for charging an undercharged cell of a bank of series connected cells utilizes a charging circuit. The charging circuit includes an inductor that receives current from the entire bank of cells and then provides current to the undercharged cell. Pulse width modulation is utilized to turn the switches on and off to regulate the current that flows to the inductor and thus is provided to the undercharged cell.
