METHOD OF MINIMIZING THE EFFECTS OF PARASITIC CURRENTS

摘要

A method of minimizing the effect of parasitic currents in secondary batteries having a plurality of cells connected electrically in series and a common electrolyte in communication with the cells is described. Specifically, the parasitic currents flowing through the battery cause a cell imbalance over the charge/discharge cycle. This cell imbalance is minimized by first separating the cells of the battery into two equal groups. Then the battery is charged with the two groups of cells connected electrically in series and subsequently discharged with the two groups of cells reconnected electrically in series in an inverted sequence.
