Title
(EN) MONITORING OF BATTERY STATE OF CHARGE
(FR) CONTRÔLE DU NIVEAU DE CHARGE D'UNE BATTERIE
Abstract
(EN) Systems and methods for monitoring a state of charge of a battery are disclosed. An updated state of charge of the battery may be determined based on a measured terminal voltage of the battery, a measured current of the battery, and a value of at least one battery parameter selected from a plurality of values based on a prior state of charge of the battery.
(FR) L'invention se rapporte à des systèmes et procédés qui permettent de contrôler le niveau de charge d'une batterie. Un niveau de charge mis à jour de la batterie peut être déterminé sur la base de la mesure d'une tension aux bornes de la batterie, de la mesure d'un courant de la batterie, et de la valeur d'un ou plusieurs paramètres de la batterie, cette valeur étant sélectionnée parmi une pluralité de valeurs sur la base d'un précédent niveau de charge de la batterie.
