Title (EN) METHOD AND APPARATUS FOR DETECTING DEFECTIVE BATTERY CELLS
(FR) PROCEDE ET DISPOSITIF DE DETECTION DE CELLULES DE BATTERIE DEFECTUEUSES
Abstract:
(EN) A device (100) has a charging system (102) for supplying a source voltage and a source current to one or more battery cells (104), a timer (107), and a processor (106) for controlling functions of the charging system. The processor is programmed to charge (204) the one or more battery cells, track (250) a charge behavior of the battery cells, determine (260, 270, 280) a profile from the charge behavior, and detect (234) one or more defective battery cells according to the profile.
(FR) L'invention concerne un dispositif (100) comportant un système de chargement (102) destiné à fournir une tension de source et un courant de source à une ou plusieurs cellules de batterie (104), une minuterie (107) et un processeur (106) destiné à commander des fonctions du système de chargement. Le processeur est programmé pour charger (204) la ou les cellules de batterie, suivre (250) un comportement de chargement des cellules de batterie, déterminer (260, 270, 280) un profil à partir du comportement de charge, et détecter (234) une ou plusieurs cellules de batterie défectueuses en fonction du profil.
