Abstract
An electrical system for a vehicle having an internal combustion engine provided with a start/stop system includes a primary battery connectible to an engine starter motor, an alternator and an electrical load in parallel with one another and selectively connectible in parallel with the primary battery via a first switch, and a third source of electrical energy selectively connectible in parallel with the alternator via a second switch. A DC/DC converter may be arranged in parallel with the alternator for selectively charging the third source of electrical energy via the second switch. A secondary battery may be arranged in parallel with the alternator.
