Abstract

A charger can read an ID code from a transponder key of an immobilizer system of a contract vehicle. When an owner of the vehicle connects a vehicle and charger with a charging cable and brings the transponder key close to a reading portion, the read ID code is transmitted from charger toward vehicle where authentication is performed. Vehicle transmits an authentication result to charger. Preferably, these transmission and reception can be performed by power line communication employing a vehicle cable.

Claims

1. A vehicle comprising:

an electric storage device;

an electric power converter for supplying and receiving electric power to and from said electric storage device;

a connecting portion for connecting an electric apparatus outside the car and said electric power converter; and

an electronic control device for reading key information stored in a vehicle key and permitting starting of said vehicle when said key information matches with registration information registered in advance in said vehicle,

wherein said electronic control device includes

a controller for controlling said electric power converter so that the converter receives said key information from said electric apparatus and supplies and receives the electric power to and from said electric storage device when said key information matches with said registration information.

2. The vehicle according to claim 1, further comprising a transmitting portion for transmitting an authentication result to said electric apparatus when said key information matches with said registration information.

3. The vehicle according to claim 1, wherein said electronic control device receives said key information via a route different from a power distribution route for supplying and receiving the electric power between said electric apparatus and said electric power converter and prohibits supply or reception of the electric power to and from said electric storage device when said key information matches with said registration information.

4. The vehicle according to claim 1, wherein said electronic control device receives said key information via a power distribution route for supplying and receiving the electric power between said electric apparatus and said electric power converter and prohibits starting of said vehicle when said key information matches with said registration information.

5. The vehicle according to claim 1,

wherein said registration information is information specific to each vehicle and

said electronic control device returns to said electric apparatus permission information indicating that said vehicle is a car permitted to use said electric apparatus when said key information matches with said registration information.

6. An electric apparatus for supplying and receiving electric power to and from an electric storage device mounted to a vehicle including an electronic control device for reading key information stored in a vehicle key and permitting starting of said vehicle when said key information matches with registration information registered in advance in the vehicle,

the electric apparatus comprising:

a reading portion for reading said key information from said vehicle key,

an electric power supplying and receiving portion for supplying or receiving the electric power to and from said electric storage device according to said key information read by said reading portion,

a transmitting portion for transmitting said key information to said vehicle when said reading portion reads said key information, and

a receiving portion for receiving a signal indicating whether or not said key information matches with the registration information registered in advance in said vehicle from said electronic control device.

8. The electric apparatus according to claim 6, further comprising a control portion for permitting supply or reception of the electric power to or from said electric storage device when said receiving portion receives the signal indicating that said key information matches with said registration information.

9. The electric apparatus according to claim 6, further comprising a control portion for storing permission information issued to a car permitted to use said electric apparatus and determining whether or not the information transmitted from said electronic control device matches with said permission information when said key information matches with the registration information registered in advance in said vehicle,

wherein said control portion permits supply or reception of the electric power to or from said electric storage device when said information transmitted from said electronic control device matches with said permission information.

10. The electric apparatus according to claim 6, further comprising a storage device for storing vehicle owner information,

wherein said signal includes said vehicle owner information and

said control portion permits supply or reception of the electric power to and from said electric storage device when said vehicle owner information stored in said storage device matches with the vehicle owner information included in said signal.

11. The electric apparatus according to claim 6, further comprising a power line cable for supplying or receiving the electric power to and from said electric storage device,

wherein said transmitting portion and said receiving portion transmits and receives said signal to and from said vehicle through said power line cable.

12. The electric apparatus according to claim 8, further comprising a power line cable for supplying or receiving the electric power to and from said electric storage device,

wherein said transmitting portion and said receiving portion transmits and receives said signal to and from said vehicle through said power line cable.

13. The electric apparatus according to claim 9, further comprising a power line cable for supplying or receiving the electric power to and from said electric storage device,

wherein said transmitting portion and said receiving portion transmits and receives said signal to and from said vehicle through said power line cable.

14. The electric apparatus according to claim 10, further comprising a power line cable for supplying or receiving the electric power to and from said electric storage device,

wherein said transmitting portion and said receiving portion transmits and receives said signal to and from said vehicle through said power line cable.
