Abstract

A power-supply monitoring device includes a capacitor that is connected to an insulated electric power source to execute charging/discharging. A power-supply monitoring device including this capacitor forms a charging path for detecting deterioration in an insulation resistance of an electric power source, and detects a voltage of the capacitor when being charged through this charging path. A vehicle controller specifies an abnormal part based on whether or not the voltage of the capacitor detected by the power-supply monitoring device is within a predetermined range.
