Abstract

La présente invention a pour objet un procédé de recalage de l’état de charge d’un système de batterie électrochimique comprenant une phase d’évaluation d’une autorisation du recalage à la suite d’une phase de relaxation comprenant les étapes de la mesure (E1) d’une tension à vide du système de batterie à la suite de la phase de relaxation, la détermination (E2) de la durée de la phase de relaxation, l’exécution d’un premier test (E3) consistant à comparer ladite durée avec un premier seuil (S1), l’exécution d’un deuxième test (E7) se basant sur la mesure (E1) de la tension à vide lorsque ladite durée (D) est supérieure au premier seuil (S1), et la détermination de l’état (E8, E9) d’une autorisation du recalage (S_AUTH) en fonction du résultat du premier test (E3) et du deuxième test (E7), un premier état (E8) de l’autorisation autorisant le recalage et un deuxième état (E9) de l’autorisation inhibant le recalage.
