Abstract

L'invention concerne un système à autodiagnostic destiné à un dispositif de stockage d'énergie, ce dernier comprenant une pluralité de piles électrochimiques connectées en série ou en parallèle pour former une série de piles. Ce système à autodiagnostic corrèle un état de santé de la batterie en fonction de la valeur de résistance interne de chaque pile électrochimique du dispositif de stockage d'énergie et détermine une capacité initiale de la batterie correspondante, ce qui permet au système à autodiagnostic d'évaluer la capacité exacte de la batterie à tout moment.
