When an ECU disconnects a second power storage device BAT2 from a drive device 90 while a hybrid vehicle is traveling, ECU disconnects one of a contact point B1 and a contact point G2 of a system main relay SMR2 and causes the vehicle to continue traveling using electric power supplied from a first power storage device BAT1 to drive device. After the vehicle finishes traveling, ECU performs a discharging operation for discharging a charge remaining in a first capacitor C1 and a second capacitor C2 with the one contact point of system main relay SMR2 being disconnected. If the charge is not discharged appropriately, ECU determines that welding occurs in at least one of system main relay SMR1 and system main relay SMR2.
