Abstract

La présente invention concerne un système de batterie comprenant des modules de batterie connectés mutuellement en série, un commutateur sélecteur et une unité de commande globale. Les modules de batterie comprennent chacun des batteries mutuellement connectées en série, une unité d'égalisation, une unité de commande de module, une conduite de dérivation et un commutateur de dérivation. Dans un module à égaliser choisi parmi les modules de batterie, lorsqu'un premier état de charge calculé à partir de l'état de charge de chacune des batteries n'est pas inclus dans une première zone dans un diagramme caractéristique des batteries, le module à égaliser est chargé ou déchargé, ce qui permet de déplacer le premier état de charge dans la première zone. Par la suite, l'état de charge de chacune des batteries est égalisé.
