Le dispositif de commande (2) acquiert en outre des informations de quantité de manque d'énergie sur la base de la quantité de stockage d'énergie estimée et d'une quantité de stockage d'énergie cible. De plus, le dispositif de commande (2) génère une liste d'un ou de plusieurs dispositifs qui peuvent être contrôlés en vue d'une économie d'énergie pendant la période de charge de la batterie secondaire (11). Ensuite, le dispositif de commande (2) ordonne à un terminal d'exploitation (3) d'afficher les informations de quantité de manque d'énergie acquises et les informations de charge contenant la liste générée.
