Abstract

L’invention concerne un système de détection pour un pack batterie (PB) de véhicule (V), comprenant - des données d’un modèle d’apprentissage (M) de prédiction d’un gradient d’augmentation de température dudit pack (PB) ; - un moyen de déterminaison d’humidité relative pour déterminer l’évolution de l’humidité dans le pack batterie (PB) ;- une unité de détection (C) ;caractérisé en ce que ladite unité (C) comporte :- un moyen pour comparer une valeur d’augmentation de température à une valeur de température prédite via les données dudit modèle (M), et détecter une grande fuite de fluide calorifique si ladite valeur d’augmentation est supérieure à ladite valeur prédite ; et- un moyen pour détecter une petite fuite de fluide ou de présence d’eau dans le pack batterie (PB) en cas d’augmentation de l’humidité relative. L’invention concerne également un procédé et un véhicule (V) sur la base d’un tel système. Fig. 1
