Title (EN) DETECTION CIRCUIT AND POWER STORAGE PACK
(FR) CIRCUIT DE DÉTECTION ET BLOC D'ACCUMULATION D'ÉNERGIE
(JA) 検出回路及び蓄電パック
Abstract:
(EN) A detection circuit 20 is provided with: a first detection unit 21 having a first input unit 21AA to which the voltage of a power storage element 12 is inputted; and a second detection unit 22 to which the voltage across both terminals of a shunt resistance 13 connected in series to the power storage element 12 is inputted, the second detection unit 22 detecting the electric current of the shunt resistance 13 on the basis of the voltage across both end parts of the shunt resistance 13; the first detection unit 21 having a second input unit 21B to which the voltage of the terminal of the shunt resistance 13 on the reverse side thereof from the power storage element 12 side is inputted, and the electric current of the shunt resistance 13 being detected on the basis of the input voltage of the first input unit 21AA and the input voltage of the second input unit 21B.
(FR) L'invention concerne un circuit de détection 20 pourvu : d'une première unité de détection 21 comportant une première unité d'entrée 21AA à laquelle est appliquée la tension d'un élément d'accumulation d'énergie 12 ; et d'une seconde unité de détection 22 à laquelle est appliquée la tension aux deux bornes d'une résistance de dérivation 13 connectée en série à l'élément d'accumulation d'énergie 12, la seconde unité de détection 22 détectant le courant électrique de la résistance de dérivation 13 sur la base de la tension aux deux parties d'extrémité de la résistance de dérivation 13 ; la première unité de détection 21 comportant une seconde unité d'entrée 21B à laquelle est appliquée la tension de la borne de la résistance de dérivation 13 de son côté opposé au côté élément d'accumulation d'énergie 12, et le courant électrique de la résistance de dérivation 13 étant détecté sur la base de la tension d'entrée de la première unité d'entrée 21AA et de la tension d'entrée de la seconde unité d'entrée 21B.
(JA) 検出回路20は、蓄電素子12の電圧が入力される第1入力部21AAを有する第1検出部21と、蓄電素子12に直列に接続されたシャント抵抗13の両端部の電圧が入力され、シャント抵抗13の両端部の電圧に基づいてシャント抵抗13の電流を検出する第2検出部22と、を備え、第1検出部21は、シャント抵抗13における蓄電素子12側とは反対側の端部の電圧が入力される第2入力部21Bを有し、第1入力部21AAの入力電圧と第2入力部21Bの入力電圧とに基づいてシャント抵抗13の電流を検出する。
