Abstract

Un procédé de surveillance est mis en œuvre dans un véhicule comprenant une batterie principale ayant des bornes entre lesquelles circule un courant, et des premier et second détecteurs propres à effectuer respectivement des premières et secondes mesures de ce courant. Ce procédé comprend une étape (10-40) dans laquelle, on détermine au moins une valeur d’écart entre les première et seconde mesures, et lorsque cette valeur d’écart est supérieure à un premier seuil choisi on impose une limitation temporaire d’une puissance électrique fournie ou reçue par la batterie principale. Figure 3A monitoring method is implemented in a vehicle comprising a main battery having terminals between which a current flows, and first and second detectors capable of respectively carrying out first and second measurements of this current. This method comprises a step (10-40) in which at least one difference value is determined between the first and second measurements, and when this difference value is greater than a first chosen threshold, a temporary limitation of electrical power supplied or received by the main battery.
