<p>A vehicle ECU (300) comprises a first ending-command unit (320), in a vehicle provided with a charging circuit for externally charging a vehicle-mounted battery with a power supply outside the vehicle. A charger ECU (400) comprises a command execution unit (410) and a current-decrease control unit (420). When a state, wherein the amount of decrease in an input voltage (Vin) inputted from a power supply outside the vehicle to the charging circuit exceeds a threshold amount (?V), continues for a prescribed period during external charging, the first ending-command unit (320) evaluates that an impedance abnormality exists, and outputs a first ending-command to the command execution unit (410). Upon receiving the first ending-command, the command execution unit (410) stops the charging circuit and ends the external charging. When the input voltage (Vin) decreases to a threshold voltage (V1) that is higher than an operation lower-limit value (Vmin) by a prescribed value's worth, the current-decrease control unit (420) controls the charging circuit so as to reduce the current flowing through the external power supply system, to inhibit further decreasing of the input voltage (Vin).</p> |
