  • Patent number: 10338141
    Abstract: A power supply protective device, when obtaining an open voltage when a second switch is brought into a closed state and a first switch is brought into an open state during discharging of a power supply, and obtaining a close voltage when the second switch is brought into the closed state and the first switch is brought into the closed state during discharging of the power supply, diagnoses the first switch as having a failure or not on the basis of the open voltage and the close voltage. When executing first a close instruction to the first switch and the second switch, if a voltage difference is less than a first threshold voltage, the first switch is determined to have no open failure, and/or when not less than a second threshold voltage, the second switch is determined to have no open failure.
