1. A battery device for providing different electrical voltage levels to be used by different electrical consumer devices in a motor vehicle, comprising:
at least two battery storage units, wherein each battery storage unit comprises a low voltage terminal and a high voltage terminal,
wherein each of the at least two battery storage units further comprises at least one intermediate voltage terminal which is connected between the low voltage terminal and the high voltage terminal of the respective battery storage unit,
wherein each of the at least two battery storage units comprises a plurality of battery cells connected in series with each other between the low voltage terminal and the high voltage terminal, wherein each of the plurality of battery cells provides a predetermined voltage,
wherein the at least one intermediate voltage terminal is connected between two adjacent battery cells of the plurality of battery cells,
wherein the at least two battery storage units are connected in series with each other,
wherein the low voltage terminal of a first battery storage unit of the at least two battery storage units is a ground terminal,
wherein the high voltage terminal of the first battery storage unit is connected to the low voltage terminal of a second battery storage unit of the at least two battery storage units,
wherein at least one intermediate voltage terminal is respectively connected between two adjacent battery cells of the first battery storage unit or the second battery storage unit, wherein the at least one intermediate voltage terminal provides an intermediate voltage output which corresponds to a sum of the predetermined voltages of the battery cells which are connected between the ground terminal and the at least one intermediate voltage terminal,
wherein the individual battery cells are attached to a connector rail which is slidingly engageable by a connector end of the at least one intermediate voltage terminal, and
wherein the at least one intermediate voltage terminal is configured to be movable and variably connectable between any two adjacent battery cells of the plurality of battery cells.
