Vehicle power supply network

摘要

The on-board network has a primary system (20) consisting of a generator, an on-board network battery and at least one load in a parallel circuit and a secondary system (30) connected in parallel with the primary system. The primary system has a driven DC/DC converter connected to a super capacitor that can be charged or discharged according to the vehicle's operating state. The super capacitor is preferably. charged during phases when the vehicle is being driven. An Independent claim is also included for a method and for an arrangement for controlling an on-board network.
