A battery system includes a plurality of battery cell packs arranged in layers selectively connected in series and parallel by a control system controlling a plurality of switches. Each of the battery cell packs includes a plurality of battery cells. A plurality of first switches and a plurality of second switches are controlled by a control system to connect the battery cell packs in response to a desired current output of the battery system and/or a desired voltage output of the battery system irrespective of individual battery cell or battery cell pack voltages or currents associated with state of charge or operational performance. The control system controls the switches to selectively connect the battery cell pack(s) to the output connections in parallel and/or series to provide redundancy and reduce output voltage/current fluctuation otherwise associated with state of charge or underperforming battery cells/packs.

Switching architecture of battery cell packs

The invention relates to a method for operating an on-board electrical network () of a motor vehicle (), with a first voltage circuit (I) and a second voltage circuit (II), the first voltage circuit (I) having a first operating voltage which is higher than a second operating voltage in the second voltage circuit (II), the first voltage circuit (I) being connected to the second voltage circuit (II) via a DC-DC converter (), and the first voltage circuit (I) having a battery () and the second voltage circuit (II) having a main battery (), characterized in that the second voltage circuit (II) has an additional third auxiliary battery (), and wherein by means of a changeover switch assembly () components of the motor vehicle () are supplied with electrical energy from the main battery () and/or the auxiliary battery (), and in that the main battery () is disconnected from the second voltage circuit (II) by means of an isolating switch () during a startup mode.
