The invention relates to a battery control assembly for a battery system. The battery control assembly includes a plurality of cell-level control units, each cell-level control unit including a cell-level switching unit operable as a cell-level inverter. The plurality of electrical core level control units are arranged into three control unit strings, and the electrical core level control units of each control unit string are electrically connected in series. The first end of each control unit string is electrically connected to a corresponding AC charging terminal. The second end of the control unit string is electrically connected in series via the first end switch and the second end switch. Further, at least one of the control unit strings includes an internal connection terminal. The invention further relates to an electric drive train for an electric vehicle having such a battery control assembly.

    本公开涉及用于电池系统的电池控制组件。电池控制组件包括多个电芯级控制单元,每个电芯级控制单元包括电芯级开关单元,该电芯级开关单元能够作为电芯级逆变器操作。所述多个电芯级控制单元布置成三个控制单元串,并且每个控制单元串的电芯级控制单元串联地电连接。每个控制单元串的第一端电连接到对应的AC充电终端。控制单元串的第二端经由第一端开关和第二端开关串联地电连接。此外,控制单元串中的至少一个包括内部连接终端。此外,提出了用于具有这样的电池控制组件的、电动车辆的电传动系。
