An electric vehicle electrical network for an electrically driven motor vehicle, a method for operating a vehicle electrical network, and an electrically driven motor vehicle having such a vehicle electrical network are disclosed. The vehicle electrical network has: a traction battery pack having a first battery pack terminal and a second battery pack terminal for providing a high voltage; a first current path between the first battery pack terminal and a first terminal for a high voltage component and a second current path between the second battery pack terminal and a second terminal for the high voltage component; and a DC voltage converter connected to a low-voltage network on an output side, the first input of the DC voltage converter being connected to a first tap between the first battery pack terminal and a first switch in the first current path and the second input of the DC voltage converter being connected to a second tap between a second switch and a second load terminal in the second current path. The electrical or electromagnetic first switch is connected into the first current path and the electrical or electromagnetic second switch is connected into the second current path.
