<p>A switch (SW3) of a connecting circuit (504) is connected between a signal line (L2) branched from an input terminal (T1) for a pilot signal (CPLT) in a charging inlet (270) and a ground line (L3) connected to a vehicle earth (518), and is turned on/off in response to a control signal from a CPU (512). The CPU (512) causes the switch (SW3) to be turned on when a connector (310) is not connected to the charging inlet (270), and detects a break in a control pilot line (L1) based on whether or not a change in the potential of the pilot signal (CPLT) occurs at that time.</p> |
