Abstract

L’invention porte sur un procédé mis en œuvre par une unité de traitement de données de surveillance de la sûreté d’une batterie, comprenant les étapes consistant à : acquérir une mesure réalisée par un capteur optique (10) comprenant une fibre optique à réseau de Bragg (F0) agencée le long d’une pluralité de cellules élémentaires (C) composant la batterie, le capteur optique étant apte à réaliser une interrogation optique du réseau de Bragg pour la détermination d’une mesure d’une modification dans la bande passante du réseau de Bragg consécutive d’une contrainte thermique ou mécanique appliquée à la fibre ;traduire la mesure de ladite modification en des données de température et de pression au niveau de chacune desdites cellules élémentaires ; etdéterminer un indicateur d’un niveau de sûreté de la batterie à partir desdites données de température et de pression. Figure pour l’abrégé : Figure 3A method implemented by a battery safety monitoring data processing unit, comprising the steps of: acquiring a measurement made by an optical sensor (10) comprising a grating optical fiber Bragg grating (F0) arranged along a plurality of elementary cells (C) making up the battery, the optical sensor being able to carry out an optical interrogation of the Bragg grating for the determination of a measurement of a modification in the band bandwidth of the Bragg grating consecutive to a thermal or mechanical stress applied to the fiber;translating the measurement of said modification into temperature and pressure data at the level of each of said elementary cells; anddetermining an indicator of a safety level of the battery from said temperature and pressure data.
