Abstract
(EN) A secondary battery (10) is configured as an assembled body of a plurality of battery modules (15). An ECU (100) calculates the degradation indexes quantitatively indicating the degradation degrees of the respective plurality of battery modules and detects a battery module, the degradation index of which has reached a predetermined replacement level, as a module-to-be-replaced. The ECU (100) further selects an additional module to be replaced at the same time as the above module-to-be-replaced from battery modules among the plurality of battery modules (15), the degradation indexes of which have not reached the replacement level.
(FR) L'invention concerne une batterie secondaire (10) configurée sous la forme d'un corps assemblé composé d'une pluralité de modules de batterie (15). Une ECU (100) calcule les indices de dégradation qui indiquent quantitativement les degrés de dégradation des modules de batteries respectifs de la pluralité et détecte un module de batterie dont l'indice de dégradation a atteint un niveau de remplacement prédéterminé en tant que module devant être remplacé. De plus, l'ECU (100) sélectionne un module additionnel à remplacer au même moment que le module devant être remplacé ci-dessus parmi les modules de batterie de la pluralité de modules de batterie (15) dont l'indice de dégradation n'a pas atteint le niveau de remplacement.
(JA)  二次電池(10)は、複数の電池モジュール(15)の集合体として構成される。ECU(100)は、複数の電池モジュールごとに、当該電池モジュールの劣化度合を定量的に示す劣化指標を算出するとともに、劣化指標が所定の交換レベルに達した電池モジュールを、交換が必要である要交換モジュールとして検出する。ECU(100)は、さらに、複数の電池モジュール(15)のうちの、劣化指標が交換レベルに達していない電池モジュールから、上記要交換モジュールと同時に交換されるべき追加交換モジュールを抽出する。
