Abstract (en)
[origin: WO2014180906A2] A drive battery (60) for n-phase operation of an electric motor (50) is provided, which comprises at least 2 * n battery strings (40), each battery string (40) having a plurality of series-connected battery cells (30), and it being possible for at least one battery cell (30) per battery string (40) to be coupled to the respective battery string (40) and decoupled from the respective battery string (40) by actuation of a coupling circuit (7) associated with the respective battery cell (30). Each battery string (40) can also be connected to one of 2 * n pole windings of an electric motor (50) that can be n-phase operated, where n Є N+ and n > 1. According to the invention, in each case two of the at least 2 * n battery strings (40) are designed to generate a constantly phase-synchronous alternating voltage by actuation of the coupling circuits (7) of the respective battery cells (30) thereof. A drive system (70) and a method for operating a drive system (70) are also provided.
