Abstract

A server comprising a processor. Further, the processor acquires credit card information and a one-time password from a vehicle connected to a charging device through a secure first communication path; acquires the one-time password from the vehicle through the charging device and a non-secure second communication path which is different from the first communication path; and charges an amount of money corresponding to an amount of power supplied by the charging device to the vehicle based on the credit card information when the one-time password acquired through the first communication path matches the one-time password acquired through the second communication path.

Claims (19)

1 . A server comprising a processor, wherein the processor is configured to

acquire credit card information and a one-time password from a vehicle connected to a charging device through a secure first communication path;

acquire the one-time password from the vehicle through the charging device and a non-secure second communication path which is different from the first communication path; and

charge an amount of money corresponding to an amount of power supplied by the charging device to the vehicle based on the credit card information when the one-time password acquired through the first communication path matches the one-time password acquired through the second communication path.

2 . The server according to claim 1 , wherein the one-time password is generated by the vehicle when the vehicle is connected to the charging device.

3 . A charging system comprising a charging device, a vehicle including a first processor, and a server including a second processor, wherein

the first processor is configured to

generate a one-time password when the vehicle is connected to the charging device,

transmit credit card information and the one-time password to the server through a secure first communication path, and

transmit the one-time password through the charging device and a non-secure second communication path which is different from the first communication path, and

the second processor is configured to

acquire the credit card information and the one-time password from the vehicle through the first communication path,

acquire the one-time password from the vehicle through the second communication path, and

charge an amount of money corresponding to an amount of power supplied by the charging device to the vehicle based on the credit card information when the one-time password acquired through the first communication path matches the one-time password acquired through the second communication path.

4 . A charging method performed by a charging system, the charging system including a charging device, a vehicle having a first processor, and a server having a second processor, the charging method comprising:

generating, by the first processor, a one-time password when the vehicle is connected to the charging device,

transmitting, by the first processor, credit card information and the one-time password through a secure first communication path,

transmitting, by the first processor, the one-time password through the charging device and a non-secure second communication path which is different from the first communication path, and

charging, by the second processor, an amount of money corresponding to an amount of power supplied by the charging device to the vehicle based on the credit card information when the one-time password acquired through the first communication path matches the one-time password acquired through the second communication path.
