Abstract

L’invention concerne un système de batterie secondaire qui convertit un courant continu alimentant des batteries secondaires (B1 à B3) en un courant alternatif au moyen d’inverseurs de courant (INV1 à INV3) et fournit le courant alternatif converti à un système électrique sur un côté de charge. Le système de batterie secondaire comprend un contrôleur (1) pour que, lorsque la quantité d’énergie restant dans la batterie secondaire qui correspond à un inverseur de courant en fonctionnement, atteint un niveau prédéterminé inférieur ou égal à une quantité d’énergie restant dans la batterie secondaire qui correspond à un inverseur de puissance arrêté, il arrête l’inverseur de puissance qui lance et exécute le fonctionnement de l’inverseur de puissance qui est arrêté.
