A vehicle comprising: a power-generating unit (22, MG1, 41); a battery configured to be charged and discharged; a power converter configured to convert electric power of the power-generating unit (22, MG1, 41) into electric power of the battery, and convert electric power of the battery into electric power of the power-generating unit (22, MG1, 41); a smoothing capacitor connected to a first power line between the power-generating unit (22, MG1, 41) and the power converter; an external power supply unit connected to a second power line between the battery and the power converter, the external power supply unit being configured to supply electric power to an outside of the vehicle; a relay connected to a point of the second power line located closer to the power converter than a point thereof to which the external power supply unit is connected, when the relay being switched ON a first portion of the second power line closer to the power converter is connected to a second portion of the second power line closer to the battery, and when the relay being switched OFF the first portion of the second power line closer to the power converter is disconnected from the second portion of the second power line closer to the battery; and a control unit configured to control the power-generating unit (22, MG1, 41) so that electric power generated by the power-generating unit (22, MG1, 41) becomes smaller than that generated when a voltage between terminals of the smoothing capacitor is equal to or larger than an output voltage of the battery, when all of conditions i) - iii) are satisfied, where i) the external power supply unit supplies electric power to the outside in a condition where a shift lever is placed in a parking position, ii) after an amount of electric power stored in the battery is reduced to be smaller than a predetermined power storage amount in a condition where the relay is switched OFF, the relay is operated to switch ON and electric power is generated by the power-generating unit (22, MG1, 41); and iii) the voltage between the terminals of the smoothing capacitor is smaller than the output voltage of the battery. a power-generating unit (22, MG1, 41); a battery configured to be charged and discharged; a power converter configured to convert electric power of the power-generating unit (22, MG1, 41) into electric power of the battery, and convert electric power of the battery into electric power of the power-generating unit (22, MG1, 41); a smoothing capacitor connected to a first power line between the power-generating unit (22, MG1, 41) and the power converter; an external power supply unit connected to a second power line between the battery and the power converter, the external power supply unit being configured to supply electric power to an outside of the vehicle; a relay connected to a point of the second power line located closer to the power converter than a point thereof to which the external power supply unit is connected, when the relay being switched ON a first portion of the second power line closer to the power converter is connected to a second portion of the second power line closer to the battery, and when the relay being switched OFF the first portion of the second power line closer to the power converter is disconnected from the second portion of the second power line closer to the battery; and a control unit configured to control the power-generating unit (22, MG1, 41) so that electric power generated by the power-generating unit (22, MG1, 41) becomes smaller than that generated when a voltage between terminals of the smoothing capacitor is equal to or larger than an output voltage of the battery, when all of conditions i) - iii) are satisfied, where i) the external power supply unit supplies electric power to the outside in a condition where a shift lever is placed in a parking position, ii) after an amount of electric power stored in the battery is reduced to be smaller than a predetermined power storage amount in a condition where the relay is switched OFF, the relay is operated to switch ON and electric power is generated by the power-generating unit (22, MG1, 41); and iii) the voltage between the terminals of the smoothing capacitor is smaller than the output voltage of the battery. i) the external power supply unit supplies electric power to the outside in a condition where a shift lever is placed in a parking position, ii) after an amount of electric power stored in the battery is reduced to be smaller than a predetermined power storage amount in a condition where the relay is switched OFF, the relay is operated to switch ON and electric power is generated by the power-generating unit (22, MG1, 41); and iii) the voltage between the terminals of the smoothing capacitor is smaller than the output voltage of the battery.
