L'invention concerne un système de batterie pour un véhicule à moteur comportant un moteur à combustion interne, le système de batterie présentant au moins un réseau de bord basse tension et un réseau de bord à tension augmentée. Le réseau de bord basse tension comporte au moins une première batterie (10) conçue pour produire une première tension et la fournir au réseau de bord basse tension, et au moins un récepteur électrique (14-2) connecté à la première batterie. Le réseau de bord à tension augmentée comporte au moins une deuxième batterie (15) conçue pour produire une deuxième tension supérieure à la première, et la fournir au réseau de bord à tension augmentée. Le réseau de bord à tension augmentée comporte également au moins un générateur électrique (11 - 13, 13-2) pouvant être entraîné par le moteur à combustion interne et conçu pour produire une troisième tension supérieure à la deuxième, et la fournir au réseau de bord à tension augmentée, en mode de fonctionnement générateur du moteur à combustion interne. Le réseau de bord à tension augmentée est connecté au réseau de bord basse tension au moyen d'une unité de couplage (17) conçue pour prélever de l'énergie électrique du réseau de bord à tension augmentée et la fournir au réseau de bord basse tension. L'invention concerne également un véhicule à moteur comportant un système de batterie correspondant.
