Abstract
Procédé d’estimation de l’état de santé d’un élément électrochimique L’invention concerne un procédé d’estimation d’un paramètre relatif à l’état de santé d’un élément électrochimique comprenant au moins une électrode comportant un mélange de matériaux actifs, le procédé comportant : - la détermination de paramètres d’un modèle de vieillissement de l’élément électrochimique donnant la valeur de la tension de l’élément lors d’une charge/décharge et modélisant : - le potentiel de chaque électrode comme une fonction appliquée à la contribution des potentiels de chaque matériau actif que comprend l’électrode, chaque contribution étant la mesure de la tension d’un système de demi-pile formé d’une électrode comportant le matériau actif et d’une contre-électrode, et - chaque mécanisme de dégradation interne de l’élément comme un décalage entre les deux potentiels des électrodes dépendant de paramètres de recalage, et - déduction d’un paramètre relatif à un état de santé de l’élément en fonction des paramètres déterminés. Figure pour l'abrégé : figure 3Method for estimating the state of health of an electrochemical element The invention relates to a method for estimating a parameter relating to the state of health of an electrochemical element comprising at least one electrode comprising a mixture of materials active, the method comprising: - the determination of parameters of an aging model of the electrochemical element giving the value of the voltage of the element during a charge/discharge and modeling: - the potential of each electrode as a function applied to the contribution of the potentials of each active material that the electrode comprises, each contribution being the measurement of the voltage of a half-cell system formed of an electrode comprising the active material and a counter-electrode, and - each internal degradation mechanism of the element such as a shift between the two potentials of the electrodes depending on adjustment parameters, and - deduction of a parameter relating to a state of health of the element according to the determined parameters.
