A drive battery for n-phase operation of an electric motor includes at least 2*n battery strings each including a plurality of series-connected battery cells. At least one battery cell per battery string is selectively connectable and disconnectable from the particular battery string by activation of a coupling circuit associated with the particular battery cell. Each battery string is also connectable to one of 2*n pole windings of an n-phase operable electric motor, where nεN+ and n>1. Two of the at least 2*n battery strings are each designed to generate an always phase-synchronous alternating voltage by activation of the coupling circuits of their particular battery cells. |
