Claim 10:
11. A method for operating a battery control system having a plurality of battery cells arranged as a plurality of controllable units that are electrically connectable in circuit via switching circuitry, each controllable unit including at least one of the battery cells of the plurality, the method comprising:
measuring conditions of at least one battery cell of each controllable unit;
estimating a state of each controllable unit based on the measured conditions of the at least one battery cell in that controllable unit, wherein the estimated state is indicative of a performance capability of that controllable unit;
performing individualized control of the controllable units, including dynamically activating and deactivating individual ones of the controllable units according to activation criteria that is based on the performance capabilities of those controllable units;
further performing the individualized control to place one or more of the controllable units, which is otherwise operative according to the activation criteria, into a resting state in which those one or more of the controllable units are temporarily maintained in a deactivated state according to cell-resting criteria which causes the one or more of the controllable units to be non-responsive to the activation criteria, while others of the controllable units are maintained in a non-resting state such that those others of the controllable units are subject to activation for durations according to the activation criteria;
wherein the cell-resting criteria calls for controllable units to be placed into the resting state based on intensity of recent usage according to a defined duration of activation of the one or more controllable units during a preceding operational period regardless of the determined performance capability of those controllable units; and
further performing the individualized control to remove the one or more of the controllable units from the resting state such that those one or more controllable units are activated for durations according to the activation criteria.
