Abstract
The invention relates to a method for operating an on-board electrical system () for a motor vehicle, wherein the on-board electrical system () has a low-voltage electrical subsystem () with at least one low-voltage load () and a starter (), and has a high-voltage electrical subsystem () having at least one high-voltage load () and one electrical generator (), wherein the high-voltage electrical subsystem () is connected to the low-voltage electrical subsystem () by means of a coupling unit () which is designed to draw energy from the high-voltage electrical subsystem () and to supply energy to the low-voltage electrical subsystem (), wherein the high-voltage electrical subsystem () has a battery () which is designed to generate the high voltage and output said high voltage to the high-voltage electrical subsystem (), and which has at least two battery units (---) with line sections (---) which are routed to the coupling unit (). In this case, the coupling unit () is designed to selectively connect the battery units (---) to the low-voltage electrical subsystem (). The invention also relates to a motor vehicle comprising an internal combustion engine and an on-board electrical system () of this kind.
