Abstract

A vehicle ECU executes a program including the steps of determining whether or not to permit discharge assistance, generating first assistance information, transmitting the first assistance information, carrying out discharge control when a result of determination as to whether or not to request discharge assistance and requested discharge electric power is received and when measures based on the result of determination can be taken, and giving notification about whether or not discharge assistance is carried out.

Claims

1. A vehicle, comprising:

a power storage device;

an engine;

a power generator for charging said power storage device with motive power from said engine; and

a control device for controlling said power generator to supply to outside of said vehicle, in addition to electric power output from said power storage device, electric power generated by said power generator as a result of operation of said engine when electric power in said power storage device is supplied to the outside of the vehicle and when a requested amount of electric power requested from the outside of said vehicle exceeds available supply electric power of said power storage device.

2. The vehicle according to claim 1, wherein

when said requested amount exceeds said available supply electric power of said power storage device, said control device determines whether to suppress generation of said generated electric power based on at least any of an amount of emission of carbon dioxide and a position of said vehicle.

3. The vehicle according to claim 2, wherein

said control device suppresses generation of said generated electric power when said requested amount exceeds said available supply electric power of said power storage device and when the position of said vehicle is in a prescribed area.

4. The vehicle according to claim 3, wherein

said prescribed area is an area where refrainment of operation of said engine is required.

5. The vehicle according to claim 2, wherein

said control device suppresses generation of said generated electric power when said requested amount exceeds said available supply electric power of said power storage device and when said amount of emission of said carbon dioxide relative to an amount of generated electric power in generation of said generated electric power is greater than a threshold value.

6. The vehicle according to claim 1, further comprising a notification unit for notifying a user of whether said generated electric power is generated.

7. A control method for vehicle used for a vehicle including a power storage device, an engine, and a power generator for charging said power storage device with motive power from said engine, comprising the steps of:

determining, when electric power in said power storage device is supplied to the outside of the vehicle, whether a requested amount of electric power requested from outside of said vehicle exceeds available supply electric power of said power storage device; and

supplying, when a requested amount of electric power requested from the outside of said vehicle exceeds available supply electric power of said power storage device, to the outside of said vehicle, in addition to electric power output from said power storage device, electric power generated by said power generator as a result of operation of said engine.

8. A power reception device for receiving electric power from a vehicle including a power storage device, an engine, and a power generator for charging said power storage device with motive power from said engine, comprising:

an electrical device operating upon receiving supply of electric power from a power supply; and

a control device for requesting to said vehicle, generation of electric power in said power generator as a result of operation of said engine when said vehicle is requested to set said power storage device as a supply source of electric power for said electrical device instead of or in addition to said power supply and when a requested amount of electric power requested to said vehicle exceeds available supply electric power of said power storage device.
