A vehicle has a first partial onboard power supply system and a second partial onboard power supply system which is electrically connected with the first partial onboard power supply system at at least a first nodal point. The first partial onboard power supply system includes a first group of electric consumers and the second partial onboard power supply system includes a second group of electric consumers. The first partial onboard power supply system includes a starter, an onboard power supply system accumulator connected parallel to the starter and a first switch between the first group of consumers and the onboard power supply system accumulator. The second partial onboard power supply system includes a first direct-voltage controller, an electric support accumulator connected parallel to the second group of electric consumers at a second modal point, and an interface of the first direct-voltage controller connected with the second nodal point. The electric support accumulator has an electric center tap, and the center tap is connected with the first nodal point by way of a second switch.
