Abstract

Un dispositif de gestion d'élément dans le dispositif de gestion de batterie rechargeable selon un mode de réalisation de l'invention comporte un circuit d'alimentation électrique de commande pour être lui-même alimenté par l'alimentation électrique opérationnelle, et gère les éléments de batterie qui constituent le module de batterie avec lequel le dispositif de gestion d'élément est associé. Un dispositif de gestion de batterie est connecté de manière à être capable de communiquer par l'intermédiaire d'une ligne de communication sans fil avec une pluralité de dispositifs de gestion d'élément, chacun constituant chaque module d'une pluralité de modules de batterie. Dans la gestion de la pluralité de modules de batterie, le dispositif de gestion de batterie délivre en sortie, par l'intermédiaire de la ligne de communication sans fil, un signal d'alimentation électrique de commande pour commander l'alimentation électrique d'un circuit d'alimentation électrique de commande. Sur la base du signal d'alimentation électrique de commande introduit, le circuit d'alimentation électrique de commande fournit une alimentation électrique opérationnelle au dispositif de gestion d'élément. Ainsi, même lorsqu'un système de batterie rechargeable à grande échelle doit être construit, le câblage à des fins de communication peut être réduit, le système peut être construit facilement, et la capacité des batteries rechargeables peut être maintenue sur une longue période.
