CHARGING CABLE INSULATION TESTING DEVICE FOR QUICK CHARGER FOR ELECTRIC VEHICLE

WIPO Patent Application WO/2011/018910

A1

In order to enable an insulation test of charging cables of a quick charger for an electric vehicle in which a ground fault detection circuit is formed between the charging cables without using an ammeter capable of wide-range measurement, the voltage reference signal of a smoothing capacitor (C) when the insulation of charging cables (13a, 13b) is normal is stored in advance in a voltage reference signal storage unit (28), the voltage of the smoothing capacitor (C) after the smoothing capacitor (C) is charged by applying voltage to the charging cables (13a, 13b) is measured by a voltmeter (23), and a comparison/determination unit (27) compares the voltage of the smoothing capacitor (C) measured by the voltmeter (23) and the voltage reference signal stored in the voltage reference signal storage unit (28) and determines whether or not the insulation of the charging cables (13a, 13b) is normal.
