Abstract

Un procédé de surveillance est mis en œuvre dans un système comprenant une batterie cellulaire connectée à un circuit électrique principal, permettant sa recharge par une source d’alimentation externe, et comportant N cellules de stockage d’énergie électrique, avec N ≥ 1, et N capteurs déterminant respectivement N tensions aux bornes de ces N cellules. Ce procédé comprend une étape (10-40) dans laquelle, lorsque dans une recharge de la batterie cellulaire l’une au moins des tensions déterminées dépasse au moins le plus petit de M seuils, avec M ≥ 2, on interdit la circulation d’un courant de recharge dans le circuit électrique principal lorsque ce dépassement dure depuis une première durée choisie associée au plus grand seuil dépassé.
