Abstract:
(EN) According to the present invention, a battery pack management device, which indicates the degree of degradation of a secondary battery cell, includes: a voltage-sensing unit for measuring the voltages of a plurality of secondary battery cells constituting a battery pack; a first monitoring unit for storing a first voltage value, i.e. each voltage value of the plurality of secondary battery cells, at the time at which all voltage values of the plurality of secondary battery cells are equal to or greater than the minimum reference voltage during a charging cycle; a second monitoring unit for storing a second voltage value, i.e. each voltage value of the plurality of secondary battery cells, at the time at which one of the voltage values of the plurality of secondary battery cells is equal to or greater than the maximum reference voltage during the charging cycle; and a control unit for calculating a separation voltage value, i.e. the value of the difference between the second voltage value and the first voltage value, and selecting a secondary battery cell having the maximum separation voltage value from among the calculated separation voltage values as a degraded cell, and updating and storing information on the degraded cell.
(FR) La présente invention concerne un dispositif de gestion d'un bloc-batterie qui indique le degré de dégradation d'une cellule de batterie secondaire et qui comprend : une unité de détection de tension pour mesurer les tensions d'une pluralité de cellules de batterie secondaire qui composent un bloc-batterie ; une première unité de surveillance pour stocker une première valeur de tension, c'est-à-dire chaque valeur de tension de la pluralité de cellules de batterie secondaire, au moment où toutes les valeurs de tension de la pluralité de cellules de batterie secondaire sont égales ou supérieures à la tension de référence minimale pendant un cycle de charge ; une deuxième unité de surveillance pour stocker une deuxième valeur de tension, c'est-à-dire chaque valeur de tension de la pluralité de cellules de batterie secondaire, au moment où l'une des valeurs de tension de la pluralité de cellules de batterie secondaire est égale ou supérieure à la tension de référence maximale pendant le cycle de charge ; et une unité de commande pour calculer une valeur de tension de séparation, c'est-à-dire la valeur de la différence entre la deuxième valeur de tension et la première valeur de tension, et sélectionner une cellule de batterie secondaire ayant la valeur de tension de séparation maximale parmi les valeurs de tension de séparation calculées comme étant une cellule dégradée, puis mettre à jour et stocker des informations sur la cellule dégradée.
