Vehicle Electrical System

A vehicle having an electrical system, which electrical system comprises a first partial electrical system having a first energy store of a first nominal voltage level, a second partial electrical system having a second energy store of a second nominal voltage level, and a DC-DC converter between the two partial electrical systems, wherein

• the first energy store comprises a housing,
• the housing has a first tap for the first nominal voltage level, by which the DC-DC converter can be electrically supplied,
• the housing has a second tap for the second nominal voltage level, by which the second energy store can be electrically supplied,
• the first tap and the second tap are galvanically isolated,
• the housing includes a voltage conversion unit, and
• the voltage conversion unit is configured to convert the electrical voltage of the first nominal voltage level to electrical voltage of the second nominal voltage level.
