Abstract

L'invention concerne un circuit de chargement permettant la commande d'un paramètre de chargement de système et affecté à un hôte de batteries rechargeables, l'hôte de batteries comprenant au moins une première batterie et une deuxième batterie pouvant être montées en parallèle. Ce circuit de chargement permet le chargement rapide des batteries rechargeables en parallèle. La détection de courant et de tension indépendante pour chaque batterie permet le chargement parallèle des batteries à différents courants de chargement. Ce circuit de chargement peut être configuré pour accepter les signaux analogiques ou bien numériques d'une unité de gestion de puissance associée.
