Abstract

Selon l'invention, le serveur de gestion d'informations (43) d'un centre d'informations d'offre/demande (40) communique avec le dispositif de commande (23) du dispositif terminal monté sur véhicule (20) d'un véhicule (10) et acquière, par exemple, des informations d'alimentation par batterie restante qui indiquent l'alimentation par batterie restante (11) du véhicule (10), chargée à des moments de production d'énergie excédentaire. Le serveur (43) détermine (ou prévoit) également le prix de vente de l'électricité et, au moyen de l'alimentation par batterie restante représentée par les informations acquises et de l'énergie restante nécessaire au fonctionnement du véhicule (10), qui est commandée en avance dans le cadre d'un contrat, prévoit le bénéfice découlant de la vente d'énergie par l'utilisateur. Ainsi, lorsque le bénéfice est déterminé, l'utilisateur (43) reçoit une notification de prévision de bénéfice qui représente le bénéfice prévu. L'utilisateur peut donc, en fonction de cette notification, obtenir le bénéfice par la vente active de l'électricité chargée dans la batterie (11), ce qui permet à une société énergétique (50) de fournir de l'énergie de façon stable, même pendant des périodes de forte demande en énergie.
