<P>PROBLEM TO BE SOLVED: To suitably perform the detection of the overvoltage state of a power accumulation device and the determination of the fusion of relay circuits, in a power supply device system. <P>SOLUTION: The power supply device system 10 includes: the power accumulation device 12; a capacitor 40 arranged between a positive electrode side line 50 and a negative electrode side line 52; the first relay circuit 16, the second relay circuit 20, and the third relay circuit 23 which operate on the basis of system start signals from the outside; and a control part which performs fusion determination processing for determining whether the first relay circuit 16, the second relay circuit 20, and the third relay circuit 23 are in normal blocked states or in fused states by discharging the electricity of the capacitor 40 after the completion of the monitoring of an overvoltage of the power accumulation device 12 in a period that blocking commands are effective in the first relay circuit 16, the second relay circuit 20, and the third relay circuit 23 after the acquisition of the system start signals. <P>COPYRIGHT: (C)2011,JPO&INPIT |
