Abstract

Ce procédé de détermination d'une matrice de covariance de bruit d'état pour le réglage d'un observateur de l'état de charge d'une batterie d'accumulateur électrique comporte les étapes de : -détermination, pour chaque point de fonctionnement d'un ensemble de points de fonctionnement de la batterie, d'une valeur d'au moins une composante (Ro, Zi) d'un modèle électrique de la batterie ; -obtention, pour chacune desdites valeurs, d'une erreur (r(SOCk)) de détermination de ladite composante ; -mémorisation des valeurs de ladite composante et des erreurs de détermination ; -calcul de l'écart type (σ[r(SOC1...p)]) des erreurs de détermination pour différents points de fonctionnement de la batterie ; et -élaboration de la matrice de covariance (Q) à partir de l'écart type calculé.
