Abstract
(EN)
A battery block (12) includes a parallel or series circuit for a plurality of battery units. Each battery unit is provided with a battery comprising at least one secondary battery. Measured voltages (VDET[1] to VDET[n]) and measured currents (IDET[1] to IDET[n]) of the batteries (1[1] to 1[n]) inside the battery units (BU[1] to BU[n]) are sent to a main control unit (11). If the batteries (1[1] and 1[2]) are connected in parallel, when the difference between IDET[1] and IDET[2] is equal to or above a prescribed value, and "IDET[1] > IDET[2]", the degradation state of the battery 1[2] is assessed as having reached a specific state; and when the difference between IDET[1] and IDET[2] is equal to or above the prescribed value, and "IDET[1] < IDET[2]", the degradation state of the battery 1[1] is assessed as having reached a specific state.
(FR)
L'invention concerne un bloc de batterie (12) comprenant un circuit parallèle ou série pour plusieurs unités de batterie. Chaque unité de batterie comprend une batterie comprenant au moins une batterie secondaire. Les tensions mesurées (VDET[1] à VDET[n]) et les courants mesurés (IDET[1] à IDET[n]) des batteries (1[1] à 1[n]) dans les unités de batterie (BU[1] à BU[n]) sont envoyés à une unité de commande principale. (11). Si les batteries (1[1] et 1[2]) sont connectées en parallèle, lorsque la différence entre IDET[1] et IDET[2] est supérieure ou égale à une valeur prédéterminée et que "IDET[1] > IDET[2]", l'état de dégradation de la batterie 1[2] est estimé comme ayant atteint un état spécifique ; lorsque la différence entre IDET[1] et IDET[2] est supérieure ou égale à une valeur prédéterminée et que "IDET[1] < IDET[2]", l'état de dégradation de la batterie 1[1] est estimé comme ayant atteint un état spécifique.

 電池ブロック12は、複数の電池ユニットの並列又は直列回路を含む。各々の電池ユニットは、1以上の二次電池から成る電池部を備える。電池ユニットBU[1]~BU[n]内の電池部1[1]~1[n]の測定電圧値VDET[1]~VDET[n]及び測定電流値IDET[1]~IDET[n]は主制御部11に送られる。電池部1[1]及び1[2]が並列接続されている場合において、IDET[1]及びIDET[2]間の差が所定値以上であって且つ"IDET[1]>IDET[2]"であるとき、電池部1[2]の劣化状態が特定状態に達したと判定し、IDET[1]及びIDET[2]間の差が所定値以上であって且つ"IDET[1]<IDET[2]"であるとき、電池部1[1]の劣化状態が特定状態に達したと判定する。
