Abstract

Le dispositif (9) d’estimation de deux états de charge (SOC1, SCO2) d’une batterie (8) comporte une pluralité de cellules (12) reliées entre elles, au moins une fraction de la pluralité de cellules formant au moins un ensemble de cellules (13, 14, 15) comportant au moins deux cellules, le dispositif comportant : - des premiers moyens de détermination (20) configurés pour déterminer un premier état de charge (SOC1) de la batterie à partir de la tension aux bornes de chaque cellule (12) et de la température au voisinage de chaque cellule, du courant circulant aux bornes de la pluralité de cellules. Le dispositif comprend en outre - des deuxièmes moyens de détermination (21) configurés pour déterminer un deuxième état de charge (SCO2) de la batterie à partir d’au moins une grandeur mesurée aux bornes de l’ensemble de cellules.
