Abstract

L'invention porte sur une automobile électrique ayant un système de génération éolien et sur son procédé de commande, dans lesquels une valeur de couple de roue (Tw) requise durant le déplacement est comparée avec une valeur de couple moteur (Tm) d'un moteur d'entraînement (120) entraîné par la puissance fournie par une batterie de stockage (140), et si la valeur du couple moteur (Tm) est supérieure à celle du couple de roue (Tw), au moins un chargeur (150) est actionné par commande conditionnelle au lieu d'éliminer une valeur de couple en surplus (Tm-Tw) inutilement consommée, conduisant ainsi à un retard de temps de consommation de puissance selon le déplacement de l'automobile électrique étant donné que la puissance générée par le chargeur (150) est plus efficacement chargée dans la batterie de stockage (140) et conduisant également à une autonomie plus longue.
