(EN) SYSTEM AND CORRESPONDING METHOD FOR ESTIMATING THE CHARGE STATUS OF A BATTERY
(FR) SYSTÈME ET PROCÉDÉ CORRESPONDANT D'ESTIMATION DE L'ÉTAT DE CHARGE D'UNE BATTERIE
Abrégé
(EN) A system for estimating the charge status of a battery comprising at least two modules (1, 2, 3 and 4) each fitted with at least one cell (13-18, 19-24, 25-30 and 31-36), said system comprising a sensor (45) for sensing the series current traversing all the cells of the modules connected in series. This system further comprises: - switching means (37-44) capable of selectively disconnecting one of the modules, the other modules remaining connected in series; and -a calculation means (46) configured to calculate the charge status of the cells traversed by said series current from the integration of the series current and to calculate the charge status of each of the cells of the disconnected module from the no-load voltage of same.
(FR) Système d'estimation de l'état de charge d'une batterie comportant au moins deux modules (1, 2, 3, 4) équipés chacun d'au moins une cellule (13-18, 19-24, 25-30, 31-36), ledit système comprenant un capteur (45) du courant série traversant l'ensemble des cellules des modules connectés en série. Ce système comprend en outre : -des moyens de commutation (37-44) capable de sélectivement déconnecter l'un des modules, les autres modules restant connectés en série; et -un moyen de calcul (46) configuré pour calculer l'état de charge des cellules traversées par ledit courant série à partir de l'intégration du courant série et pour calculer l'état de charge de chacune des cellules du module déconnecté à partir de leur tension à vide.
