Title:
LOAD CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/017119
Kind Code:
A1
Abstract:
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.
