A method and apparatus for estimation of the augmented state of an electrochemical cell, the method comprising: making an internal augmented states prediction of the cell where the augmented state comprises at least one internal state value and at least one internal parameter value; making an uncertainty prediction of the internal augmented states prediction; correcting the internal augmented states prediction and the uncertainty prediction; and applying an algorithm that iterates the making an internal augmented states prediction, the making an uncertainty prediction and the correcting to yield an ongoing estimation to the augmented state and an ongoing uncertainty to the augmented state estimation.
L'invention concerne un procédé et un appareil d'estimation de l'état de recharge d'une cellule électrochimique. Ledit procédé consiste à prévoir l'état de recharge interne de la cellule, l'état de recharge comprenant au moins une valeur d'état interne et au moins une valeur de paramètre interne, à effectuer une prévision d'incertitude de la prévison d'état de recharge interne, à corriger la prévision de l'état de recharge interne et la prévision d'incertitude, et à appliquer un algorithme d'itération de la prévision d'état de recharge interne, de la prévision d'incertitude, et de la correction afin d'obtenir une estimation continue de l'état de recharge et une incertitude continue de l'estimation de l'état de recharge.
