Abstract

An electronic device that includes an interface that connects to a charging apparatus and exchanges authentication information with a server via a network. The electronic device also includes a control unit that controls charging of a battery of the electronic device based on power received from the charging apparatus. Upon completion of the charging operation, the interface of the electronic device transmits information for calculating a tax based on the charging operation to the server.

Claims

1. An electronic device comprising:

an interface configured to connect to a charging apparatus and exchange authentication information with a server via a network;

a control unit configured to control charging of a battery of the electronic device based on power received from the charging apparatus, wherein

the interface is configured to transmit information for calculating tax to the server.

2. The electronic device according to claim 1, wherein

the information for calculating the tax is at least one of an amount of charge received by the battery, battery identification information, driver identification information and car identification information.

3. The electronic device of claim 1, wherein

the interface is configured to receive permission to initiate the charging of the battery upon an indication that authentication with the server is successful.

4. The electronic device of claim 1, wherein

the interface is configured to receive a confirmation that the server received the information for calculating the tax.

5. The electronic device of claim 4, further comprising:

a drive control unit configured to disable a motor of the electronic device until the confirmation is received from the server.

6. The electronic device of claim 1, wherein

the interface is configured to exchange the authentication information with the server over the network via the charging apparatus.

7. The electronic device according to claim 1, wherein

the authentication information is generated based on a secret key assigned to the electronic device.

8. The electronic device of claim 1, wherein

the information for calculating the tax is an amount of charge received by the battery.

9. The electronic device of claim 8, wherein

the information for calculating the tax is attached with a signature generated based on a secret key assigned to the electronic device.

10. A non-transitory computer-readable medium including computer program instructions, which when executed by an electronic device, cause the electronic device to perform a method comprising:

connecting to a charging apparatus;

exchanging authentication information with a server via a network;

controlling charging of a battery of the electronic device based on power received from the charging apparatus; and

transmitting information for calculating a tax to the server.

11. A method performed by an electronic device, the method comprising:

connecting, by an interface of the electronic device, to a charging apparatus;
