CHARGE SYSTEM FAILURE JUDGING DEVICE AND FAILURE JUDGING METHOD

摘要

An ECU executes a program including a step (S118) of determining that a pilot wire for transferring a pilot signal CPLT, which is output when a charging cable is connected to a plug-in hybrid vehicle and an external power source, to the ECU is broken, when output of the pilot signal CPLT is currently stopped (YES in S100) and a voltage VAC of the external power source (absolute value of voltage VAC) detected by a voltmeter provided within the plug-in hybrid vehicle is greater than zero (NO in S114).
