Abstract
A cell balancing software program that executes on a computer system embedded inside a multi-cell battery and includes a means to control an external charging system. When a charge imbalance is detected between the cells, a cell balancing algorithm is selected from a plurality of cell-balancing algorithms and is executed. The executed algorithm causes a charge request, which specifies desired charging parameter(s), to be generated, and the charge request is transmitted to the external charging system. After the external charging system charges the battery according to the charge request, the effectiveness of the cell-balancing algorithm can be evaluated and stored in a history. The history can be used to select cell balancing algorithm(s) for future cell balancing.
