A system for balancing charge between cells in a battery uses switches to connect a capacitor across a cell and then to connect the capacitor to a control circuit that measures the charge in the cell. This sequence is repeated for each cell until the charge in each cell has been measured. A high-voltage cell and a low-voltage cell are therefore be determined, and charge is transferred from the high-voltage cell to the low voltage cell using the capacitor. An inductor may be provided in series with the capacitor to allow more efficient charging and discharging of the cells. In this way a substantially uniform change on each cell can be maintained. |
