First Claim
Patent Images
1. A method for controlling charging of a battery, the method comprising:
- determining an actual full charge capacity of a battery and a design capacity of the battery;
comparing the actual full charge capacity of the battery with the design capacity of the battery;
adjusting one or more of a charge voltage or a cut-off current if the actual full charge capacity is less than the design capacity; and
controlling the battery, wherein controlling the battery includes charging the battery with one or more of an adjusted cut-off current or an adjusted charge voltage.

Abstract
A charging operation for a battery includes determining an actual full charge capacity of the battery and a design capacity of the battery. The actual full charge capacity of the battery is compared with the design capacity of the battery. One or more of a charge voltage and a cut-off current, such as with an embedded controller, is adjusted if the actual full charge capacity is less than the design capacity. The battery is controlled by charging the battery with one or more of an adjusted cut-off current and/or an adjusted charge voltage.

9. An apparatus for controlling a charging operation of a battery, the apparatus comprising:
-
a battery cell;
a charging module configured to adjust a cut-off current and a charge voltage of the battery cell; and
an embedded controller configured to determine a state of the battery cell and to determine the charge voltage and the cut-off current based on a combination of the charge voltage and the cut-off current, wherein the embedded controller is configured to deliver a control signal to the charging module based on the determined charge voltage and the determined cut-off current. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
