Abstract
(EN)
A storage battery device according to one embodiment of the present invention is provided with: a plurality of cell modules each provided with a plurality of battery cells; a data acquisition unit that acquires voltage data for each of the battery cells; a calculation unit that calculates a rate of increase of an internal resistance value with respect to the initial value thereof on the basis of the voltage data for each of the battery cells; and a storage unit that stores the rate of increase of the internal resistance value with respect to the initial value thereof.
(FR)
Selon un mode de réalisation, la présente invention concerne un dispositif de batterie de stockage pourvu : d'une pluralité de modules de cellule pourvus chacun d'une pluralité de cellules de batterie ; d'une unité d'acquisition de données qui acquiert des données de tension pour chacune des cellules de batterie ; d'une unité de calcul qui calcule un taux d'augmentation d'une valeur de résistance interne par rapport à sa valeur initiale sur la base des données de tension pour chacune des cellules de batterie ; et d'une unité de stockage qui stocke le taux d'augmentation de la valeur de résistance interne par rapport à sa valeur initiale.
