Abstract

Unité de stockage d'un système de batterie de stockage qui, selon un mode de réalisation, pré-stocke la relation correspondante entre les motifs de distribution de fréquence de SOC d'un dispositif de batterie de stockage et les paramètres de commande du dispositif de batterie de stockage. Une unité de détermination différencie un motif de distribution de fréquence de SOC pour la distribution de fréquence du SOC du dispositif de batterie de stockage dans une période de temps prédéfinie, ledit SOC étant mesuré à des intervalles d'un temps prédéfini lorsque le système de batterie de stockage fonctionne, et détermine un paramètre de commande du dispositif de batterie de stockage en référence à l'unité de stockage. Par conséquent, un mode de fonctionnement approprié pour l'utilisateur (ou un système appliqué) peut être présenté ou commandé automatiquement.
