<p>A method of operating a battery system includes a plurality of battery cells (24,26,28,30) coupled in series. The plurality of cells (24,26,28,30) includes at least three battery cells coupled in series. The method includes determining a cell with the greatest charge excess of the plurality of battery cells (24,26,28,30). The method further includes determining a cell with the greatest charge deficit of the plurality of battery cells (24,26,28,30). The method further includes discharging the cell with the greatest charge excess to charge, with a voltage converter, the cell with the greatest charge deficit.</p> |
