要約
(EN)
The present invention detects, with a high degree of accuracy, a break in voltage detection lines connected to a battery pack and a plurality of cascade-connected voltage detection circuits and maintains an SOC balance between the battery cells of the battery pack. A plurality of cascade-connected voltage detection ICs (1-4) detect, via a plurality of voltage detection lines, the voltages of a plurality of serially connected battery cells that compose a battery pack. The plurality of voltage detection ICs (1-4) operate by receiving power from the battery pack. The plurality of voltage detection ICs (1-4) are connected by communication lines, and at least one of the plurality of voltage detection ICs (1-4) is connected to a control circuit (7). First to third dummy resistors (R1-R3) are connected to the voltage detection ICs (1-3) from among the plurality of voltage detection ICs (1-4) that do not directly communicate with the control circuit (7). First to third switches (S1-S3) respectively turn the supply of current to the first to third dummy resistors (R1-R3) on and off.

La présente invention permet de détecter avec une grande précision une rupture des lignes de détection de tensions reliées à un bloc-batterie et à une pluralité de circuits de détection de tensions montés en cascade, et de maintenir l'équilibre du SOC entre les éléments de batterie du bloc-batterie. Une pluralité d'IC de détection de tensions (1-4) montés en cascade détectent, par le biais d'une pluralité de lignes de détection de tensions, les tensions d'une pluralité d'éléments de batterie montés en série qui constituent un bloc-batterie. Lesdits IC de détection de tensions (1-4) fonctionnent grâce à l'énergie reçue en provenance du bloc-batterie. Ces IC de détection de tensions (1-4) sont reliés par des lignes de communication, et un ou plusieurs d'entre eux sont reliés à un circuit de commande (7). Trois résistances fictives (R1-R3) sont reliées aux IC de détection de tensions (1-3) de la pluralité d'IC de détection de tensions (1-4) qui ne communiquent pas directement avec le circuit de commande (7). Trois commutateurs (S1-S3) activent et désactivent respectivement l'alimentation électrique des trois résistances fictives (R1-R3).

 組電池の電池セル間のSOCバランスを維持しつつ、組電池と、カスケード接続された複数の電圧検出回路に接続される電圧検出線の断線を高精度に検出する。カスケード接続される複数の電圧検出用IC(1~4)は、組電池を構成する直列接続された複数の電池セルの各電圧を、複数の電圧検出線を介して検出する。複数の電圧検出用IC(1~4)は、組電池から電源供給を受けて動作する。複数の電圧検出用IC(1~4)間は通信線で接続されており、複数の電圧検出用IC(1~4)の少なくとも一つは、制御回路(7)に接続されている。第1ダミー抵抗(R1)~第3ダミー抵抗(R3)は、複数の電圧検出用IC(1~4)の内、制御回路(7)と直接通信しない電圧検出用IC(1~3)に接続される。第1スイッチ(S1)~第3スイッチ(S3)は、第1ダミー抵抗(R1)~第3ダミー抵抗(R3)への電流供給をそれぞれオン/オフする。
