Abstract

A vehicle is provided with an electrical storage device, a first connector capable of charging and discharging the power of the electrical storage device, a second connector capable of charging and discharging the power of the electrical storage device, and an ECU for controlling charging and discharging performed via the first connector and the charging and discharging performed via the second connector. The ECU selects and implements any one of the following according to the operation of an operation unit provided to a first plug connected to the first connector: discharging from the electrical storage device via the first connector, charging to the electrical storage device via the first connector, discharging from the electrical storage device via the second connector, and charging to the electrical storage device via the second connector.

Claims

1. A vehicle capable of supplying electric power to outside the vehicle, comprising:

a power storage device;

a first connecter capable of charging and discharging electric power of said power storage device;

a second connecter capable of charging and discharging electric power of said power storage device; and

a control device that controls charging and discharging provided via said first connector, and charging and discharging provided via said second connector,

said control device being operative in response to a control portion being operated to select and perform any one of discharging said power storage device via said first connector, charging said power storage device via said first connector, discharging said power storage device via said second connector, and charging said power storage device via said second connector, said control portion being provided at a first plug connected to said first connector.

2. The vehicle according to claim 1, wherein:

said control portion is configured to be capable of issuing a charge instruction or a discharge instruction and a perform instruction of charging or discharging; and

said control device is signaled of a state of said control portion via said first connector, and when said control device receives said discharge instruction and also receives said perform instruction, said control device performs discharging said power storage device to outside the vehicle, and when said control device receives said charge instruction and also receives said perform instruction, said control device allows electric power to be received from outside the vehicle to perform charging said power storage device.

3. The vehicle according to claim 2, wherein:

when said control device receives said perform instruction and said discharge instruction via said first connector, with a second plug unconnected to said second connector, said control device performs discharging said power storage device to outside the vehicle via said first connector; and

when said control device receives said perform instruction and said discharge instruction via said first connector, with said second plug connected to said second connector, said control device performs discharging said power storage device to outside the vehicle via said second connector.

4. The vehicle according to claim 1, wherein:

said second connector is configured to allow a second plug to be connected thereto, said second plug being provided at one end of a cable having the other end connected to a power conditioner station;

said control portion is configured to be capable of issuing a first pattern signal and a signal of a pattern different from said first pattern signal;

when said control device receives said first pattern signal via said first connector, with said second plug connected to said second connector, said control device allows electric power to be received from outside the vehicle via said first connector or said second connector to perform charging said power storage device; and

when said control device receives said signal different from said first pattern signal via said first connector, with said second plug connected to said second connector, said control device performs discharging said power storage device to outside the vehicle via said first connector or said second connector.

5. The vehicle according to claim 4, wherein:

said control portion is configured to be capable of issuing a charge instruction or a discharge instruction and a perform-charging-or-discharging instruction;

said second connector includes an input node to receive from said power conditioner station a signal indicative of a command to start discharging from said power storage device to said power conditioner station; and

when said control device receives said charge instruction or said discharge instruction via said first connector, with said first plug connected to said first connector, and said second plug connected to said second connector, instead of said power conditioner station, said control device outputs to said input node a signal indicative of said command to start discharging.

6. The vehicle according to claim 2, wherein:

said second connector is configured to allow a second plug to be connected thereto, said second plug being provided at one end of a cable having the other end connected to a power conditioner station;

the vehicle further comprises a first CAN communication unit;

said power conditioner station includes a second CAN communication unit; and

when said control device receives an instruction from said control portion, with said second plug connected to said second connector, said control device initiates said first CAN communication unit to perform communication.

7. The vehicle according to claim 1, wherein:
