Abstract

Quand un commutateur principal (70) se trouve dans un état désactivé, une unité de commande (50) connecte une première extrémité d'un condensateur (C) à un premier commutateur (10) à l'aide d'un second commutateur (15) et déconnecte une première extrémité d'une batterie (B) et le second commutateur (15) l'un de l'autre à l'aide du premier commutateur (10). Quand un moteur de démarrage (46) doit être activé en amenant le commutateur principal (70) dans un état activé, la première extrémité du condensateur (C) est connectée au premier commutateur (10) par le second commutateur (15), et la première extrémité de la batterie (B) est connectée au second commutateur (15) par le premier commutateur (10), ce qui permet de connecter la batterie (B) au condensateur (C) en série. Une fois que le moteur à combustion interne (60) a démarré, la première extrémité du condensateur (C) est connectée au premier commutateur (10) par le second commutateur (15), et la première extrémité de la batterie (B) et le second commutateur (15) sont déconnectés l'un de l'autre par le premier commutateur (10).
