(JA) 電池パック
Abstract:
(EN) According to the present invention, a battery pack is provided with: a battery; a voltage detection unit for detecting the voltage of the battery; and an estimation unit for estimating, as an open circuit voltage after depolarization of the battery, the result of adding a value obtained by multiplying the ratio of the first voltage to the second voltage by a coefficient to the first voltage detected by the voltage detection unit after a first predetermined time elapses from the start of a rest period or to the second voltage detected by the voltage detection unit after a second predetermined time elapses from the start of the rest period, or the result of subtracting a value obtained by multiplying the ratio by the coefficient from the first voltage or the second voltage.
(FR) La présente invention concerne un bloc-batterie comprenant : une batterie ; une unité de détection de tension permettant de détecter la tension de la batterie ; et une unité d'estimation permettant d'estimer, en tant que tension de circuit ouvert après la dépolarisation de la batterie, le résultat de l'addition d'une valeur obtenue par la multiplication du rapport de la première tension à la deuxième tension par un coefficient, à la première tension détectée par l'unité de détection de tension après qu'un premier temps prédéfini s'écoule depuis le début d'une période de repos, ou à la deuxième tension détectée par l'unité de détection de tension après qu'un deuxième temps prédéfini s'écoule depuis le début de la période de repos, ou le résultat de la soustraction d'une valeur obtenue par la multiplication du rapport par le coefficient de la première tension ou de la deuxième tension.
(JA) 電池と、電池の電圧を検出する電圧検出部と、休止期間開始から第1の所定時間経過後に電圧検出部により検出される第1の電圧もしくは休止期間開始から第2の所定時間経過後に電圧検出部により検出される第2の電圧に、第1の電圧と第2の電圧との比と、係数とを乗算した値を加算した結果、または、第1の電圧もしくは第2の電圧から、比と係数とを乗算した値を減算した結果を、電池の分極解消後の開回路電圧として推定する推定部とを備えて電池パックを構成する。
