Abstract
A dual voltage supply circuit for vehicles is disclosed, in particular for vehicles with a dual circuit electrical braking system. The circuit contains a starter battery and an auxiliary battery, each supplying an electrical braking circuit. The two batteries are charged from a three phase generator which has power diodes and excitation diodes. The auxiliary battery is charged via an electrical path from the excitation diodes. A monitoring module, which includes a charge monitoring system and a time delay, is connected in series between the excitation diodes and the auxiliary battery.
