ADJUSTING CHARGE VOLTAGE ON CELLS IN MULTI-CELL BATTERY
First Claim
1. A method for charging a battery pack containing a plurality of cells, the method comprising:
- receiving capacity information for a voltage adjustable set of the plurality of cells from two or more fuel gauges, each of the two or more fuel gauges associated with one cell in the adjustable set;
identifying a target cell for increasing charge voltage based on the capacity information;
and sending a signal to a charge voltage controller associated with the target cell, the signal configured to cause the charge voltage controller to increase charge voltage on the target cell, the charge voltage controller one of a plurality of charge voltage controllers, each of the plurality of charge voltage controllers associated with one or more cells in the voltage adjustable set.

Abstract
A method for charging a battery pack containing a plurality of cells is disclosed. The method includes receiving capacity information for a voltage adjustable set of the plurality of cells from two or more fuel gauges. Each of the two or more fuel gauges is associated with one cell in the adjustable set. The method further includes identifying a target cell for increasing charge voltage based on the capacity information. The method further includes sending a signal to a charge voltage controller associated with the target cell. The signal is configured to cause the charge voltage controller to increase charge voltage on the target cell. The charge voltage controller is one of a plurality of charge voltage controllers. Each of the plurality of charge voltage controllers is associated with one or more cells in the voltage adjustable set.
