Abstract

La présente invention concerne une station de recharge mobile à fonctionnement autonome stable, comprenant : un équipement de production d'énergie 3 qui génère de l'énergie électrique à partir de la lumière du soleil ; une batterie de stockage du système qui stocke l'énergie électrique générée par l'équipement de production d'énergie 3 ; un chargeur 5 qui charge une batterie de stockage embarquée 21 ; un équipement de réception d'énergie comprenant un dispositif de gestion ; et le dispositif de gestion. Lorsque l'énergie est générée par l'équipement de production d'énergie 3, le dispositif de gestion donne : une première priorité à l'alimentation en énergie électrique générée par l'équipement de production d'énergie 3 à l'équipement de réception d'énergie, et à la charge de la batterie de stockage du système à une première capacité prédéterminée inférieure à la charge complète avec l'énergie électrique générée par l'équipement de production d'énergie 3 ; une deuxième priorité à la charge complète de la batterie de stockage du véhicule 21 connectée au chargeur 5 ; et une troisième priorité à la charge complète de la batterie de stockage du système.
