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. Figure 4The present invention relates to a method for recalibrating the state of charge of an electrochemical battery system comprising a phase of evaluating an authorization of the recalibration following a relaxation phase comprising the steps of measuring (E1) an open-circuit voltage of the battery system following the relaxation phase, determining (E2) the duration of the relaxation phase, performing a first test (E3) consisting of comparing said duration with a first threshold (S1), performing a second test (E7) based on the measurement (E1) of the open-circuit voltage when said duration (D) is greater than the first threshold (S1), and determining the state (E8, E9) of an authorization of the recalibration (S_AUTH) as a function of the result of the first test (E3) and the second test (E7), a first state (E8) of the authorization authorizing the recalibration and a second state (E9) of the authorization inhibiting the recalibration.
