Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a charging control device for a vehicle which detects disconnection of a control line where a pilot signal is transmitted. SOLUTION: One end of a resistor R2 is connected to a terminal T1 and the other end of the resistor R2 to a terminal T2. A control pilot line L1 for transmitting the pilot signal CPLT is connected to the terminal T1. When a charging connector 25 is not connected to a connector 261, a switch 312 is turned off. A voltage-generating circuit 504 sets the terminal T2 at potential higher than vehicle ground potential. When the charging connector 25 is not connected to the connector 261 and the control pilot line L1 is disconnected, the potential produced in the control pilot line L1 is substantially at the ground level. CPU 512 detects the disconnection, based on the potential of the control pilot line L1. COPYRIGHT: (C)2009,JPO&INPIT
