Abstract

A vehicle includes a power feeding inverter that converts at least one of power discharged by a storage apparatus and power generated by activating an engine into alternating current power. The vehicle detects the presence of a user within a predetermined range of the vehicle using at least one of a seat occupancy sensor, a camera provided on the exterior or in the interior of the vehicle, and a reception unit that receives ratio waves from a smart key. When a request for power feeding from the vehicle is issued but the user has not been detected within the predetermined range of the vehicle, power generation by activating the engine is prohibited.

Claims

1. A vehicle comprising:

a storage apparatus configured to be recharged;

a power generation mechanism configured to generate power using a different energy source from the storage apparatus;

a power feeding apparatus configured to supply power obtained from at least one of the storage apparatus and the power generation mechanism, from the vehicle;

a detector configured to detect a user within a predetermined range of the vehicle; and

a controller configured to prohibit power generation by the power generation mechanism when a request for power feeding from the vehicle is issued and the user has not been detected within the predetermined range.

2. The vehicle according to claim 1, wherein, the controller activates the power generation mechanism and the power feeding apparatus feeds the power obtained from the power generation mechanism from the vehicle, when a state of charge of the storage apparatus is lower than a first determination value and the user has been detected within the predetermined range while the request for power feeding from the vehicle is issued.

3. The vehicle according to claim 2, wherein, the controller stops the power generation by the power generation mechanism and the power feeding apparatus feeds the power obtained from the storage apparatus from the vehicle, when the state of charge exceeds a second determination value while power generation by the power generation mechanism is underway, the second determination value is larger than the first determination value.

4. The vehicle according to claim 1, wherein, the controller prohibits power feeding from the vehicle, when a state of charge of the storage apparatus is lower than a first determination value and the user has not been detected within the predetermined range.

5. The vehicle according to claim 1, further comprising:

a connection port configured to electrically connect the vehicle to an exterior located outside the vehicle,

wherein the power feeding apparatus is configured to supply power to the exterior located outside the vehicle through the connection port.

6. The vehicle according to claim 1, further comprising:

a power outlet provided in a vehicle cabin,

wherein the power feeding apparatus is configured to supply power from the power outlet.

7. The vehicle according to claim 1, wherein the power generation mechanism includes an engine that generates power by burning fuel, and a motor generator that generates power using an output of the engine.

8. A power supply system comprising:

a vehicle including;

a cable connection port,

a storage apparatus configured to be recharged,

a power generation mechanism configured to generate power using a different energy source from the storage apparatus,

a first power feeding apparatus configured to supply power obtained from at least one of the storage apparatus and the power generation mechanism to the cable connection port,

a detector configured to detect a user within a predetermined range of the vehicle, and

a controller configured to prohibit power generation by the power generation mechanism when the user is not detected within the predetermined range; and

a second power feeding apparatus configured to supply power supplied from the vehicle to a load located outside the vehicle, the second power feeding apparatus being configured to be electrically connected to the cable connection port via a power cable when a charging-discharging connector provided on the power cable is connected to the cable connection port.

9. The power supply system according to claim 8, wherein the vehicle includes a power outlet provided in a vehicle cabin, and the first power feeding apparatus is configured to supply power from the power outlet.

10. The power supply system according to claim 8, wherein the vehicle includes a charger that converts power, supplied to the cable connection port from outside the vehicle via the charging-discharging connector and the power cable, into power to be charged to the storage apparatus.
