Abstract

L'invention porte sur un système de gestion de batterie pour délivrer en sortie un signal, lequel système est apte à déterminer si une erreur s'est produite ou non. Le système de gestion de batterie selon la présente invention comprend une pluralité d'unités de gestion de batterie mesurant la tension d'une batterie secondaire et commandant la charge et la décharge de cette dernière. Les unités de gestion de batterie délivrent en sortie des signaux quand la batterie secondaire gérée par ces derniers est surchargée ou sur-déchargée et que des erreurs se produisent dans les unités elles-mêmes. À cet instant, la pluralité d'unités de gestion de batterie délivrent en sortie les signaux à des lignes connectées en série. Dans le système de gestion de batterie selon la présente invention, les formes d'onde des signaux devant être délivrés en sortie changent en fonction de la quantité de courant circulant dans les lignes connectées en série.
