Abstract

Procédé d’auto-paramétrage des conditions de charge d'une batterie d'accumulateurs électrochimiques, notamment une batterie lithium, ladite batterie étant connectée à une source d'alimentation apte à la charger, comprenant : la détection d’au moins un point p d’inflexion dans la courbe de tension de charge de la batterie Ubat fonction du taux de charge électrique exprimé en pourcentage de la capacité C de la batterie ;pour chaque point p d’inflexion détecté, une déconnexion de la batterie de sa source d’alimentation pendant une période de relaxation prédéterminée ;à l’issue de ladite période de relaxation, la mémorisation de la tension à vide UxR de la batterie pour chacun des points d’inflexion, ladite tension à vide UxR constituant un marqueur d’un niveau de charge intermédiaire utilisable comme seuil d’arrêt de charge au cours de la charge d’une batterie.
