20100237830 | System and Method for Balancing Charge Within a Battery Pack - A system for balancing charge within a battery pack with a plurality of cells connected in series, including a capacitor; a processor configured to select a combination of donor cells and receiver cells from the plurality of cells in one of the following two modes: (1) a first mode where the number of donor cells is equal to the number of receiver cells, and (2) a second mode where the number of donor cells is greater than the number of receiver cells; and a plurality of switches that electrically connect the capacitor to the donor cells to charge the capacitor, and that electrically connected the capacitor to the receiver cells to discharge the capacitor. The transfer of charge between cells in the plurality of cells through the capacitor balances the charge within the battery pack. | 09-23-2010 |
