Abstract
A vehicle includes a charging unit receiving electric power supplied from an external power supply through a power feeding cable connected to an inlet for charging a power storage device; a discharging unit for supplying electric power from the power storage device to the power feeding cable through the inlet; a discharge relay; and a charge relay. When ending a discharging operation, an ECU outputs an opening instruction to the discharge relay and determines based on the state of a power line during output of the opening instruction whether the discharge relay is welded or not. When starting the discharging operation, the ECU outputs a closing instruction to the discharge relay and does not determine during output of the closing instruction whether the discharge relay is welded or not.
