Abstract

A plug-in vehicle has a door lock system which uses an electronic certification key. The electronic certification key stores a certification code and has a wireless communication device to transmit the code. A management system for charging the plug-in vehicle has a wireless communication device which can receive the certification code from the key, and a key verification module which verifies whether a proper key exists at the charging station or not. If a proper key is detected, the system permits charging the plug-in vehicle from a power outlet. On the other hand, if a proper key is not detected, the system denies and prohibits charging the plug-in vehicle from the power outlet.

Claims

1. A management system for charging a plug-in vehicle, comprising:

a communication module which retrieves identification information from a key with an electronic certification to perform locking and releasing of a door lock in the plug-in vehicle; and

a security module which includes a verification module for verifying whether there is a proper key or not based on the identification information retrieved by the communication module, and which permits a charging activity to the plug-in vehicle when detecting a proper key, or refuses the charging activity when detecting no proper key.

2. A management system for charging a plug-in vehicle, comprising:

a communication module which retrieves position information from a vehicle navigation system, the position information being capable of identifying the plug-in vehicle or a user; and

a security module which includes a verification module for verifying whether the position information retrieved by the communication module is proper or not, and which permits a charging activity to the plug-in vehicle when detecting a proper position information, or refuses the charging activity when detecting no proper position information.

3. A management system for charging a plug-in vehicle, comprising:

a network communication module which retrieves identification information capable of identifying a plug-in vehicle or a user supplied from a component belonging to the plug-in vehicle through a network communication device related to the plug-in vehicle; and

a security module which permits a charging activity to the plug-in vehicle when the identification information retrieved by the network communication module is proper, and refuses the charging activity when no proper identification information is retrieved.

4. The management system for charging a plug-in vehicle claimed in claim 3, wherein

the network communication module includes:

a vehicle side wireless LAN communication device which transmits the identification information supplied from an identification information storage device belonging to the plug-in vehicle to a wireless LAN; and

a station side wireless LAN communication device located on a charging station, which performs wireless communication with the vehicle side wireless LAN communication device, and wherein

the security module is located on the charging station, and includes a verification controller which retrieves the identification information via the station side wireless LAN communication device, and which permits a charging activity to the plug-in vehicle when the identification information is proper, and refuses the charging activity when no proper identification information is retrieved.

5. The management system for charging a plug-in vehicle claimed in claim 4, wherein

the verification controller performs a verification of the identification information in response to an event in which the vehicle side wireless LAN communication device and the station side wireless LAN communication device are placed within a wireless communication range, even before a connector on the charging station and a connector on the plug-in vehicle are connected.

6. The management system for charging a plug-in vehicle claimed in claim 4, wherein

the vehicle side wireless LAN communication device and the station side wireless LAN communication device initiate communication via the wireless LAN when a connection between a connector on the charging station and a connector on the plug-in vehicle is provided or after the connection is provided, and then, the verification controller performs a verification of the identification information.

7. The management system for charging a plug-in vehicle claimed in claim 3, wherein

the network communication module includes:

a WAN communication device which transmits the identification information supplied from an identification information storage device belonging to the plug-in vehicle to the Internet; and

a server computer located on a charging station, which is connectable with the Internet, and wherein

the security module includes;

a verification controller located on the charging station, which retrieves the identification information via the server computer, and which permits a charging activity to the plug-in vehicle when the identification information is proper, and refuses the charging activity when no proper identification information is retrieved.

8. The management system for charging a plug-in vehicle claimed in claim 7, wherein

the verification controller performs a verification of the identification information in response to an event in which the plug-in vehicle is located within a predetermined distance from the charging station, even before a connector on the charging station and a connector on the plug-in vehicle are connected.

9. The management system for charging a plug-in vehicle claimed in claim 7, wherein

the WAN communication device and the server computer connect to the Internet when a connection between a connector on the charging station and a connector on the plug-in vehicle is provided or after the connection is provided, and then, the verification controller performs a verification of the identification information.

10. The management system for charging a plug-in vehicle claimed in claim 3, wherein

the network communication module includes:

a WAN communication device which transmits the identification information supplied from a vehicle side identification information storage device belonging to the plug-in vehicle to the Internet; and

an internet communication device located on a charging station, which is connectable with the Internet and is capable of transmitting identification information supplied from a station side identification information storage device belonging to the charging station to the Internet, and wherein

the security module includes;

a verification controller located on an information center connected with the Internet, which retrieves the identification information from the vehicle side identification information storage device and the identification information from the station side identification information storage device, and which permits a charging activity to the plug-in vehicle when the identification information are proper, and refuses the charging activity when no proper identification information is retrieved.

11. The management system for charging a plug-in vehicle claimed in claim 3, wherein

the network communication module includes:

a WAN communication device which transmits the identification information supplied from an identification information storage device belonging to the plug-in vehicle to the Internet;

an internet communication device located on a charging station, which is connectable with the Internet; and

an information center connected to the Internet, and wherein

the security module includes;

a verification controller located on the charging station, which is connected to the internet communication device, and retrieves the identification information from the vehicle side identification information storage device via the information center, and which permits a charging activity to the plug-in vehicle when the identification information is proper, and refuses the charging activity when no proper identification information is retrieved.
