Abstract

Un dispositif de protection (DP) équipe une batterie (BV) comprenant un boîtier (BB) installé dans un soubassement (SV) d'un véhicule (V). Ce dispositif (DP) comprend : - un écran de protection (EP) installé sous une face externe inférieure (FEI) du boîtier (BB) et comportant une chambre (CE) comportant un gaz sous une pression connue, - un capteur de pression (CP) installé au moins partiellement dans la chambre (CE) et mesurant la pression régnant dans cette chambre (CE), et - un circuit d'analyse (CA) comparant chaque pression mesurée à la pression connue, et générant un signal d'alerte lorsqu'au moins une pression mesurée est inférieure à la pression connue.
