Abstract
A method for operating a battery of an at least partially electrically operated/driven functional device, a corresponding battery, and a corresponding functional device. A control unit of the battery receives measurement signals relating to a respective parameter of the battery cells from a plurality of switchable battery cells of the battery. The control unit prepares a location-resolved distribution function of the respective cell parameter within the battery on the basis of the measurement signals. By activating the switching elements of the switchable battery cells according to a predetermined switching rule, the control unit produces a pattern of battery cells switched to active and passive. A predetermined location-resolved distribution function of the respective cell parameter is fulfilled and at least one predetermined secondary condition relating to an operation of the functional device and/or the battery is maintained.
