Abstract

La présente invention se rapporte à un dispositif de commande de tous les consommateurs ou de quelques consommateurs d'une pluralité de consommateurs qui reçoivent le courant d'un réseau électrique et commande la charge et la décharge d'une batterie rechargeable destinée à être utilisée pour la traction et qui est montée dans un véhicule électrique. Le dispositif de commande comprend une unité d'instruction et une unité d'ajustement. L'unité d'instruction détermine une période de contre-mesure pendant laquelle la tension du réseau électrique est prédite pour dépasser la limite supérieure d'une plage limitée, et ordonne la charge de la batterie rechargeable de telle sorte que la tension du réseau électrique soit maintenue dans la plage limitée pendant la période de contre-mesure. L'unité d'ajustement ajuste la capacité restante de la batterie rechargeable avant la période de contre-mesure de telle sorte que la charge pour maintenir la tension du réseau électrique dans la plage limitée pendant la période de contre-mesure soit rendue possible.
