摘要:
A multi-voltage vehicle electrical system for a motor vehicle is provided, including at least one multi-voltage generator, a first energy store, whose energy may be fed into a first low-voltage vehicle electrical system branch having low-voltage consumers, and a second energy store, whose energy may be fed into a second high-voltage vehicle electrical system branch having high-voltage consumers, as well as at least one controllable switching device, using which the energy generated by the multi-voltage generator may be distributed to the first and the second vehicle electrical system branches, the first and the second energy stores being connected in series to one another and the first vehicle electrical system branch being connected to a node between the first and the second energy store and to a reference potential of the first energy store.
