Abstract

Un procédé surveille des tensions aux bornes de cellules de stockage d’énergie électrique faisant partie d’une batterie cellulaire équipant un système. Ce procédé comprend une étape (10-40) dans laquelle, lorsque dans une phase de décharge de la batterie cellulaire l’une au moins des tensions déterminées dépasse au moins un premier seuil choisi, on effectue dans le système au moins une action fonction du dépassement. Fig. 3A method monitors voltages at the terminals of electrical energy storage cells forming part of a cellular battery fitted to a system. This method comprises a step (10-40) in which, when in a discharge phase of the cellular battery at least one of the determined voltages exceeds at least a first chosen threshold, at least one action is carried out in the system depending on the exceeding.
