Beschreibung
Zusammenfassung:	A two-voltage battery for a vehicle, having at least one ground terminal, a first vehicle electrical system connection at which a low, first vehicle electrical system voltage is provided, and a second vehicle electrical system connection at which a high, second vehicle electrical system voltage is provided. At least one battery submodule having at least two battery cell blocks and a multiplicity of switching elements is provided for connecting the battery cell blocks in parallel and/or in series as desired. In a first connection arrangement, the same are connected in parallel with one another such that the first vehicle electrical system voltage is provided at the first vehicle electrical system connection. The switching elements in a second connection arrangement connect the battery cell blocks in series with one another such that the second vehicle electrical system voltage is provided at the second vehicle electrical system connection.
