Title (EN) BATTERY MANAGEMENT SYSTEM
(FR) SYSTÈME DE GESTION DE BATTERIE
(KO) 배터리 관리 시스템
Abstract:
(EN) The present invention relates to a battery management system, comprising: at least one cell group including first and second battery cells which are connected in parallel between first and second bus bars; a plurality of first and second measurement terminals formed on the first and second bus bars; a plurality of third and fourth measurement terminals which are formed on the first bus bar at positions corresponding to one end of each of the first and second battery cells; a cell voltage measurement unit for measuring a cell voltage of the cell group by using the first and second measurement terminals; a voltage drop measurement unit for measuring an error voltage corresponding to the resistance of the first bus bar by using the third and fourth measurement terminals; and a battery management unit for calculating a cell correction voltage by using the cell voltage and the error voltage.
(FR) La présente invention concerne un système de gestion de batterie, comprenant : au moins un groupe de cellules comportant des première et seconde cellules de batterie qui sont connectées en parallèle entre des première et seconde barres omnibus ; une pluralité de premières et deuxièmes bornes de mesure formées sur les première et seconde barres omnibus ; une pluralité de troisièmes et quatrièmes bornes de mesure qui sont formées sur la première barre omnibus à des positions correspondant à une extrémité de chacune des première et seconde cellules de batterie ; une unité de mesure de tension de cellule permettant de mesurer une tension de cellule du groupe de cellules à l'aide des premières et deuxièmes bornes de mesure ; une unité de mesure de chute de tension permettant de mesurer une tension d'erreur correspondant à la résistance de la première barre omnibus à l'aide des troisièmes et quatrièmes bornes de mesure ; et une unité de gestion de batterie permettant de calculer une tension de correction de cellule à l'aide de la tension de cellule et de la tension d'erreur.
