Abstract

L'invention concerne notamment un dispositif (100) de gestion d'équipement électrique comportant une unité (122) de planification à long terme, une unité (124) de planification à court terme et une unité (125) de commande d'équipement électrique. L'unité (122) de planification à long terme détermine un plan à long terme pour commander un équipement électrique pendant une période de planification à long terme d'après une valeur de prédiction de la quantité totale d'énergie consommée pendant la période de planification à long terme. L'unité (124) de planification à court terme détermine un plan à court terme pour commander l'équipement électrique pendant une période de planification à court terme plus courte que la période de planification à long terme d'après le plan à long terme déterminé par l'unité (122) de planification à long terme. L'unité (125) de commande d'équipement électrique commande l'équipement électrique comprenant un accumulateur d'après le plan à court terme déterminé par l'unité (124) de planification à court terme et une valeur de résultat indiquant une capacité restante réelle de l'accumulateur.
