Abstract

L'invention concerne un procédé destiné à faire fonctionner une batterie secondaire possédant au moins deux cellules de batterie, notamment d'un véhicule à propulsion électrique, en utilisant une stratégie de fonctionnement mémorisée s'appuyant sur des modèles de vieillissement spécifiques associés aux cellules de batterie individuelles, comprenant au moins les étapes suivantes : - acquisition d'au moins deux paramètres d'état différents spécifiques à une cellule de chaque cellule de batterie ; - détermination d'un état de vieillissement spécifique de chaque cellule de batterie en se basant sur les paramètres d'état spécifiques acquis auprès des cellules de batterie respectives ; - détermination des dépendances de l'état de vieillissement spécifique de chaque cellule aux paramètres d'état individuels de chaque cellule de batterie ; - comparaison des dépendances déterminées avec des dépendances correspondantes définies à l'avance, contenues dans le modèle de vieillissement spécifique de la cellule de batterie respective ; - en présence d'un écart entre les dépendances déterminées et les dépendances définies à l'avance du modèle de vieillissement spécifique de la cellule de batterie respective, adaptation du modèle de vieillissement spécifique d'une cellule de batterie aux dépendances déterminées ; - détermination de la durée de vie d'une cellule de batterie en se basant sur le modèle de vieillissement spécifique de la cellule de batterie adapté aux dépendances déterminées ; - comparaison de la durée de vie déterminée d'une cellule de batterie avec une valeur de seuil prédéfinie ; et - adaptation de la stratégie de fonctionnement lorsque la durée de vie déterminée d'une cellule de batterie devient inférieure au seuil prédéfini.
