The disclosure relates to a battery control assembly (18) for a battery system (19). The battery control assembly (18) comprises a plurality of cell-level control units (22), each comprising a cell-level switching unit being operable as a cell-level inverter. The plurality of cell-level control units (22) are arranged in three control unit strings (28, 30, 32) and the cell-level control units (22) of each control unit string (28, 30, 32) are electrically connected in series. First ends (28a, 30a, 32a) of each control unit string (28, 30, 32) are electrically connected to a corresponding AC charging terminal (34a, 34b, 34c). Second ends (28b, 30b, 32b) of the control unit strings (28, 30, 32) are electrically connected in series via a first end switch (54) and a second end switch (56). Moreover, at least one of the control unit strings (28, 30, 32) comprises an inner connection terminal (28c, 30c, 32c). Furthermore, an electric drivetrain (10) for an electric vehicle having such a battery control assembly (18) is presented.
