Provided is an authentication method and apparatus that enables a charging station to verify a contract certificate of an electric vehicle on the basis of a cross-certificate in a situation where there are a multiple of MOs and the charging station does not have an MO root certificate. An electric vehicle certification method according to an aspect of the present disclosure may be performed for PnC charging of the electric vehicle in a charging station device configured to charge an electric vehicle. The electric vehicle certification method comprises: a step for transmitting to the electric vehicle a SECC certificate chain including a power supply device communication controller (SECC) certificate and at least one charging device series sub-certificate used to generate the SECC certificate, and receiving a result of verification of the SECC certificate from the electric vehicle; a step for receiving a contract certificate chain including a contract certificate from the electric vehicle; and a step for, when a cross-certificate is included in the contract certificate chain, verifying the cross-certificate on the basis of a predetermined root certificate, obtaining a public key of a charging operator root certification authority or a charging operator subordinate certification authority included in the cross-certificate, and verifying the contract certificate on the basis of the obtained public key.
