CROSS-CERTIFICATION METHOD AND DEVICE FOR CHARGING ELECTRIC VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18039168 titled 'CROSS-CERTIFICATION METHOD AND DEVICE FOR CHARGING ELECTRIC VEHICLE
Simplified Explanation
The abstract describes an authentication method and device for a charging station to verify a contract certificate of an electric vehicle using a cross certificate when the station does not have an MO RootCA certificate. The method involves transmitting an SECC certificate chain to the electric vehicle, receiving a verification result, receiving a contract certificate chain, and verifying the cross certificate and contract certificate based on predetermined certificates.
- Explanation of the patent:
- Transmit SECC certificate chain to EV - Receive verification result - Receive contract certificate chain - Verify cross certificate based on RootCA certificate - Verify contract certificate based on obtained public key
Potential Applications
The technology can be applied in electric vehicle charging stations, smart grids, and IoT devices that require secure authentication processes.
Problems Solved
1. Ensures secure authentication of electric vehicles in charging stations 2. Enables plug-and-charge functionality without the need for MO RootCA certificate

Original Abstract Submitted
An authentication method and device enable a charging station to verify a contract certificate of an electric vehicle based on a cross certificate when the charging station is not equipped with an MO RootCA certificate. An electric vehicle authentication method for providing plug-and-charge charging to the electric vehicle in the charging station includes: transmitting, to the electric vehicle, an SECC certificate chain including an SECC certificate and at least one charging device family SubCA certificate and receiving a verification result for the SECC certificate from the electric vehicle; receiving a contract certificate chain including a contract certificate from the electric vehicle; and verifying the cross certificate based on a predetermined RootCA certificate to obtain a public key of a charging operator RootCA or a charging operator SubCA included in the cross certificate and verifying the contract certificate based on an obtained public key.
