  • the control device 15 of the present invention is used in any of the above-described power management systems, and includes a prediction unit 153 and a notification unit 154.
  • the user who confirms the notification of the notification unit 154 supplies electric power from the electric vehicle 20 to the distribution network 31 in the excess period predicted by the prediction unit 153 by connecting the electric vehicle 20 to the charge / discharge device 16 Can. Therefore, in the excess period predicted by prediction unit 153, the amount of power received from power system 30 can be suppressed, and thereby the peak of the amount of power received from power system 30 can be suppressed.

Abstract

L'invention porte sur un système de gestion d'énergie comprenant une unité de conversion d'énergie et un dispositif de commande comprenant une unité de prédiction et une unité de notification. L'unité de conversion d'énergie est connectée de manière détachable à un véhicule électrique ayant un moteur électrique en tant que source d'énergie et possède une fonction qui fournit une énergie déchargée depuis le véhicule électrique vers un réseau de distribution d'énergie qui fournit une énergie reçue depuis un réseau d'énergie vers une pluralité de charges. L'unité de prédiction prédit une période d'excès dans laquelle la somme de la demande d'énergie par la pluralité de charges connectées au réseau de distribution d'énergie dépassera une limite prescrite. L'unité de notification réalise une notification demandant que le véhicule électrique soit connecté à l'unité de conversion d'énergie et soit apte à une décharge durant la période d'excès prédite par l'unité de prédiction.
