When detecting an abnormality, an in-vehicle wireless instrument in a plug-in vehicle sends an abnormality occurrence notification to a mobile terminal via an information center. The mobile terminal performs a notification to notify a user of the abnormality having occurred in the plug-in vehicle. When the user performs a charging forbiddance manipulation based on the notification, the mobile terminal sends a charging forbidding command to a power management ECU in the vehicle via the information center and the in-vehicle wireless instrument. When receiving the charging forbidding command, the power management ECU stops charging a battery using an external power source, and sends a setting completion notification to the mobile terminal via the in-vehicle wireless instrument and the information center. When receiving the setting completion notification, the mobile terminal notifies the user that the charging is stopped.
