Abstract
An electric vehicle charging control system may include an electric vehicle which extracts current time information, the integrity of which has been verified, by use of a public key cryptography, and charges power from a charging terminal, when it is determined that a charging contact certificate is valid, based on the extracted current time information, a server to transmit the current time information, the integrity of which has been verified using the public key cryptography, to the electric vehicle, and the charging terminal connected to the electric vehicle. The validity of the certificate used in vehicle charging and billing for charging is determined through the power line communication, and the security against the hacking is enhanced in the charging of the electric vehicle.
