BATTERY CONTROL ASSEMBLY FOR A BATTERY SYSTEM AND ELECTRIC DRIVETRAIN FOR AN ELECTRIC VEHICLE

A battery control assembly for a battery system. The battery control assembly includes a plurality of cell-level control units, each including a cell-level switching unit being operable as a cell-level inverter. The plurality of cell-level control units are arranged in three control unit strings and the cell-level control units of each control unit string are electrically connected in series. First ends of each control unit string are electrically connected to a corresponding AC charging terminal. Second ends of the control unit strings are electrically connected in series via a first end switch and a second end switch. Moreover, at least one of the control unit strings includes an inner connection terminal. Furthermore, an electric drivetrain for an electric vehicle having such a battery control assembly is presented.
