Abstract

Selon la présente invention, un dispositif de commande d'alimentation électrique comprend un dispositif de réception électrique destiné à recevoir de l'électricité provenant d'un générateur électrique, une pluralité de dispositifs de connexion ayant chacun une partie de connexion de cellule à laquelle est connectée une cellule de stockage, et un dispositif de commande. Le dispositif de commande est configuré de manière à déterminer si une quantité d'électricité produite qui est fournie au dispositif de réception électrique par le générateur électrique est au moins une quantité d'électricité nécessaire, qui est une quantité d'électricité nécessaire pour charger toutes les cellules de stockage connectées aux parties de connexion; à exécuter une première opération d'alimentation électrique dans laquelle de l'électricité est fournie par le dispositif de réception électrique à tous les dispositifs de connexion auxquels sont connectées les cellules de stockage lorsque la quantité d'électricité produite est déterminée comme étant au moins la quantité d'électricité nécessaire; et à exécuter une seconde opération d'alimentation électrique lorsque la quantité d'électricité produite est déterminée comme étant inférieure à la quantité d'électricité nécessaire, dans laquelle de l'électricité est fournie par le dispositif de réception électrique à certains des dispositifs de connexion auxquels sont connectées les cellules de stockage mais de l'électricité n'est pas fournie par le dispositif de réception électrique au reste des dispositifs de connexion.
