Title
(EN) METHOD AND SYSTEM FOR PREDICTING BATTERY DEGRADATION
(FR) PROCÉDÉ ET SYSTÈME DE PRÉDICTION DE DÉGRADATION DE BATTERIE
Abstract
(EN)
We describe a system and method for analysing batteries. The method may comprise measuring a set of variables for a battery; selecting parameters for a degradation model which predicts degradation of the battery and which comprises a calendar ageing component and a cycling ageing component; predicting a predicted degradation value for the battery using the degradation model and the selected parameters; obtaining an estimated degradation value for the battery using the set of measured variables; updating the parameters for the degradation model based on the predicted and estimated degradation values and outputting a final degradation value based on the estimated and predicted degradation values.

L'invention concerne un système et un procédé d'analyse de batteries. Le procédé selon l'invention peut consister : à mesurer un ensemble de variables pour une batterie ; à sélectionner des paramètres pour un modèle de dégradation qui prédit la dégradation de la batterie et comprend une composante de vieillissement calendaire et une composante de vieillissement en cycles ; à prédire une valeur de dégradation prédite pour la batterie au moyen du modèle de dégradation et des paramètres sélectionnés ; à obtenir une valeur de dégradation estimée pour la batterie au moyen de l'ensemble de variables mesurées ; à mettre à jour les paramètres pour le modèle de dégradation en fonction des valeurs de dégradation prédites et estimées, et à émettre en sortie une valeur de dégradation finale, en fonction des valeurs de dégradation estimées et prédites.
