Abstract

L'invention concerne un procédé d'évaluation de l'état d'une batterie électrochimique, appartenant à un réseau électrique, notamment un réseau de bord d'un véhicule automobile, comprenant outre une batterie (2), au moins une source d'énergie électrique (1) contrôlée et des consommateurs (3) d'énergie électrique.Le procédé consiste à appliquer (E1 ) une variation temporelle (DG) de tension ou de courant aux bornes de la batterie (2), à mesurer (E3) la réponse de la batterie (B) et à déduire l'état de la batterie (Etat_Batt) d'une fonction (f1)) prédéterminée dépendant de ladite variation (DG), de ladite réponse (B) et de la température Tbat de la batterie.The invention relates to a method for evaluating the state of an electrochemical battery, belonging to an electrical network, in particular an onboard network of a motor vehicle, comprising in addition to a battery (2), at least one source of electrical energy (1) controlled and consumers (3) of electrical energy.The method consists in applying (E1) a temporal variation (DG) of voltage or current across the battery (2), to be measured (E3) the response of the battery (B) and to deduce the state of the battery (Etat_Batt) of a predetermined function (f1)) dependent on said variation (DG), said response (B) and the temperature Tbat of the drums.
