摘要:
A charging system (108) supplies a source voltage (Vco, FIG. 5) and a source current (Ico, FIG. 5) to a plurality of battery cells (110). The charging system operates according to a method (200) including the steps of determining (202) a capacity for each of the plurality of battery cells (120 and 130), determining (204) a desired cutoff current (Ico1, FIG. 5) for a select one of the plurality of battery cells (120) having the smallest capacity, determining (206) an optimal source cutoff current according to the capacity of the select one of the plurality of battery cells, adjusting (208) the source current according to the optimal source cutoff current, and periodically applying (209) the source current after reaching the optimal source cutoff current.
