Abstract

Il est proposé un procédé d'estimation de l’état de santé (SoH) d’une batterie comprenant un ou plus éléments électrochimiques. Pendant que la batterie est utilisée, le procédé charge ou décharge un composant de stockage, pour ensuite le décharger ou le recharger afin de pouvoir mesurer la capacité réelle du composant de stockage. Le SoH est calculé à partir d’une précédente valeur connue de la capacité du composant de stockage et de la capacité réelle du composant de stockage. Figure pour l’abrégé : Fig. 1
