Abstract

Un procédé d’estimation est mis en œuvre dans un système comprenant une batterie comportant au moins une cellule, et comprend une étape d’estimation (50-60) dans laquelle on détermine un gradient de température sur une partie d’une face de la cellule à partir de mesures fournies par un capteur de température installé sur cette face dans un intervalle de temps choisi lorsque la batterie est utilisée avec une puissance électrique courante et un état de charge courant, puis on détermine une valeur d’un rapport entre ce gradient de température déterminé et un gradient de température estimé fourni, pour ces intervalle de temps, puissance électrique courante et état de charge courant, par un réseau de neurones ayant fait l’objet d’un apprentissage statistique préalable d’estimation de gradient de température pour la batterie, cette valeur étant représentative d’une estimation d’un état de santé de la batterie.
