Abstract

L’estimation de l’état d’énergie (SOE) pour un instant donné comporte : - une réception (602) de mesures d’une température (T) de la cellule (111), d’une tension (U) de la cellule (111) et d’un courant (I) échangé par la cellule (111) ; - une estimation d’une résistance interne (R) de la cellule (111) ; - une estimation d’une tension de circuit ouvert (OCV) de la cellule (111) ; - une estimation d’une énergie totale (Etot) délivrée par la cellule (111) jusqu’à l’instant donné ; - une estimation d’une énergie maximale (Emax) pouvant être délivrée par la cellule (111) en supposant que la température (T) et le courant (I) restent constants ; et - une soustraction de l’énergie totale délivrée (Etot) estimée à l’énergie maximale (Emax) estimée.
