Document Type and Number:
Japanese Patent JP6770184
Kind Code:
B2
Abstract:
The purpose of the present invention is to reduce a diagnosis time. A power supply system (10, 20, 30, 40) has: battery devices (13, 23, 33, 43); switches (14, 24, 34, 44) connected in series to the respective battery devices; and voltmeters (15, 25, 35, 45) for measuring the voltages of circuits composed of the respective battery devices and switches. A device for controlling the power supply system in which power supply devices (10, 20, 30, 40) are connected in parallel turns on the switch of at least one power supply device and performs fault diagnosis on the basis of the voltage values of the power supply devices to which the switches in an off state belong.
