The invention relates to a method for operating a vehicle electrical system (52) for a motor vehicle (50), wherein a vehicle battery (54) of the vehicle electrical system (52) that has at least two sub-batteries (26, 28) provides electrical energy from more than one of the at least two sub-batteries (26, 28) at a conventional supply terminal (46) of the vehicle electrical system (52), said conventional supply terminal being electrically coupled to the vehicle battery (54). According to the invention, at least a first and a second safety supply terminal (42, 44) of the vehicle electrical system (52) are supplied with electrical energy by means of a coupling device (10, 40) of the vehicle electrical system (52), the coupling device being connected to the vehicle battery (54), and the coupling device (10, 40) electrically coupling the at least a first and second safety supply terminal (42, 44) each to exactly one of the at least two sub-batteries (26, 28) in accordance with a coupling state of the coupling device (10, 40).
