(EN) SYSTEMS AND METHODS FOR REAL-TIME PARAMETER ESTIMATION OF A RECHARGEABLE BATTERY
(FR) SYSTÈMES ET PROCÉDÉS D'ESTIMATION DE PARAMÈTRES EN TEMPS RÉEL D'UNE BATTERIE RECHARGEABLE
Abstract
(EN)
A battery system includes a battery that couples to an electrical system. The battery system also includes a battery control module that electrically couples to the battery. The battery control module monitors at least one monitored parameter of the battery, and the battery control module recursively calculates at least one calculated parameter of the battery based on at least an equivalent circuit model, the at least one monitored parameter, and a Kalman filter.
(FR)
L’invention concerne un système de batterie comprenant une batterie qui s'accouple à un système électrique. Le système de batterie comprend également un module de commande de batterie qui s'accouple électriquement à la batterie. Le module de commande de batterie surveille au moins un paramètre surveillé de la batterie et le module de commande de batterie calcule de façon récursive au moins un paramètre calculé de la batterie en fonction d'au moins un modèle de circuit équivalent, du au moins un paramètre surveillé et d'un filtre de Kalman.
