ADJUSTING CHARGE VOLTAGE ON CELLS IN MULTI-CELL BATTERY |
| 摘要 |
A battery pack includes a plurality of cells. Two or more fuel gauges are associated with a voltage adjustable set of the plurality of cells. Each of the two or more fuel gauges is associated with one cell in the voltage adjustable set. Each of the two or more fuel gauges is configured to communicate cell capacity of the associated cell to a master controller. Two or more charge voltage controllers are associated with the voltage adjustable set. Each of the two or more charge voltage controllers is associated with one or more cells in the voltage adjustable set. Each of the two or more charge voltage controllers is configured to receive a signal from the master controller. Each of the two or more charge voltage controllers is configured to increase charge voltage on the associated one or more cells in response to receiving the signal. |
