In a method for operating a vehicle electrical system for a motor vehicle, a vehicle battery of the vehicle electrical system that has at least two sub-batteries provides electrical energy from more than one of the at least two sub-batteries at a conventional supply terminal of the vehicle electrical system, the conventional supply terminal being electrically coupled to the vehicle battery. At least a first and a second safety supply terminal of the vehicle electrical system are supplied with electrical energy by a coupling device of the vehicle electrical system, the coupling device being connected to the vehicle battery, and the coupling device electrically coupling the at least a first and second safety supply terminal each to exactly one of the at least two sub-batteries in accordance with a coupling state of the coupling device.
