Abstract

A power supply for a motor vehicle includes an additional voltage storage associated with the starter and the starter is separated from the rest of the vehicle supply system during the starting process by a charging/separating module. Since different variables of the vehicle supply system are supplied to this charging/separating module and corresponding measurements and detection take place within this module, the charging/separating module itself switches off or switches over in a manner which is optimally adapted to requirements. Since the voltage storage associated with the starter and the rest of the vehicle supply battery can be operated completely independently from one another, they can be freely selected based on requirements (starting or buffering). A particularly reliable and safe charging of this voltage storage is ensured at a reduced nominal voltage of the voltage storage, also designated as starter storage.
