The invention relates to a method for operating an on-board electrical system (52) for a motor vehicle (50), in which more electrical energy than one of the at least two sub-cells (26, 28) is provided from a vehicle battery (54) of the on-board electrical system (52) having the at least two sub-cells (26, 28) at a conventional supply connection (46) of the on-board electrical system (52) that is electrically coupled to the vehicle battery (54). According to the invention, at least one first and one second safety supply connection (42, 44) of the on-board electrical system (52) are supplied with electrical energy via a coupling device (10, 40) of the on-board electrical system (52) connected to the vehicle battery (54), the coupling device (10, 40) being connected to the on-board electrical system (52) depending on a coupling state of the coupling device (10, 40). At least one first and one second safety supply connection (42, 44) are each electrically coupled to exactly one of the at least two sub-cells (26, 28).

    本发明涉及一种用于运行用于机动车(50)的车载电网(52)的方法,其中,由具有至少两个子电池(26、28)的车载电网(52)的车辆电池(54),在车载电网(52)的与车辆电池(54)电耦联的传统的供给联接部(46)处提供比至少两个子电池(26、28)中的一个更多的电能。根据本发明提出,车载电网(52)的至少一个第一和第二安全供给联接部(42、44)通过联接在车辆电池(54)处的车载电网(52)的耦联装置(10、40)供给电能,其中,耦联装置(10、40)根据耦联装置(10、40)的耦联状态,使至少一个第一和第二安全供给联接部(42、44)分别与至少两个子电池(26、28)中的刚好一个电耦联。
