Abstract

L'invention se rapporte à un procédé d'estimation d'un paramètre physique d'une cellule électro-chimique de stockage d'énergie comportant une étape d'estimation (10) dudit paramètre par un observateur d'état modélisant la cellule comme une source de tension et n circuits RC parallèles connectés en série, où n est un entier supérieur ou égal à 1. Selon l'invention, le procédé comporte, si la valeur estimée du paramètre est dans une plage prédéfinie, une étape de correction (12) de ladite estimation incluant la prise en compte dans l'observateur d'un terme correctif en tension, ledit terme correspondant à au moins un (n + 1)ème circuit RC parallèle connecté en série avec la source de tension.
