An onboard electrical system is disclosed that includes first, second and third onboard electrical sub-systems for an electric drive unit, electric components and a vehicle battery of a vehicle, respectively. In addition, the system includes a charging terminal, wherein a changeover switch, a first switch element, and a second switch element of the onboard electrical system are physically separated from one another. The charging terminal is galvanically connected to the third onboard electrical sub-system by the first switch element and to the second onboard electrical sub-system by the changeover switch during an electric charging mode of the vehicle battery. The first onboard electrical sub-system is galvanically connected to the third onboard electrical sub-system of the second switch element and to the second onboard electrical sub-system by the changeover switch during a driving mode of the vehicle.
