Title (EN) LOAD CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE DE CHARGE
(JA) 負荷制御装置
Abstract:
(EN) According to the present invention, while suppressing an increase in a circuit scale, the disconnection of a reflux path through which a reflux current flows is detected. A battery monitoring device 3 is provided with: switching circuits 13a, 13b for controlling a current flowing through each coil of main contactors 7a, 7b under an on/off control; reflux diodes 14a, 14b that are connected to each coil of the main contactors 7a, 7b to form a reflux path for circulating a current; and a control unit 11. The control unit 11 measures output voltages of the reflux diodes 14A, 14b at an input terminal ADCd, and detects the disconnection of the reflux path on the basis of the measured output voltages of the reflux diodes 14a, 14b.
(FR) Selon la présente invention, tout en supprimant une augmentation dans une échelle de circuit, la déconnexion d'un trajet de reflux à travers lequel circule un courant de reflux est détectée. Un dispositif de surveillance de batterie (3) comprend : des circuits de commutation (13a, 13b) permettant de commander un courant circulant à travers chaque bobine de contacteurs principaux (7a, 7b) dans le cadre d'une commande marche/arrêt ; des diodes de reflux (14a, 14b) qui sont connectées à chaque bobine des contacteurs principaux (7a, 7b) pour former un trajet de reflux permettant de faire circuler un courant ; et une unité de commande (11). L'unité de commande (11) mesure les tensions de sortie des diodes de reflux (14a, 14b) au niveau d'une borne d'entrée (ADCd), et détecte la déconnexion du trajet de reflux sur la base des tensions de sortie mesurées des diodes de reflux (14a, 14b).
(JA) 回路規模の増大を抑えつつ、還流電流が流れる還流経路の断線を検知する。 電池監視装置3は、オンオフ制御されてメインコンタクタ7a、7bの各コイルに流れる電流を制御するスイッチング回路13a、13bと、メインコンタクタ7a、7bの各コイルに接続されて電流を還流するための還流経路を形成する還流ダイオード14a、14bと、制御部11とを備える。制御部11は、還流ダイオード14a、14bの出力電圧を入力端子ADCdにおいて測定すると共に、測定された還流ダイオード14a、14bの出力電圧に基づいて、還流経路の断線を検知する。
