Charging Authentication Method and Apparatus - A simplified explanation of the abstract
This abstract first appeared for US patent application 17965906 titled 'Charging Authentication Method and Apparatus
Simplified Explanation
The abstract describes a charging authentication method and apparatus for improving the security of communication between an electric vehicle and a charging spot. The method involves establishing multiple connections between the electric vehicle, charging spot, and charging management system. The electric vehicle sends a charging request message to the charging spot using a controller area network (CAN) bus. Identity authentication and key negotiation are then performed between the electric vehicle and the charging spot using a second connection and a third connection between the charging spot and the charging management system.
- The method involves establishing a first connection between the electric vehicle and the charging spot using a controller area network (CAN) bus.
- A second connection is established between the electric vehicle and a charging management system using a mobile communication network.
- The electric vehicle sends a charging request message to the charging spot using the first connection.
- Identity authentication and key negotiation are performed between the electric vehicle and the charging spot using the second connection and a third connection between the charging spot and the charging management system.
Potential Applications
- Electric vehicle charging systems
- Smart grid infrastructure
- Electric vehicle charging networks
Problems Solved
- Improving security of communication between electric vehicles and charging spots
- Preventing unauthorized access to charging spots
- Ensuring secure and authenticated charging transactions
Benefits
- Enhanced security for electric vehicle charging
- Protection against unauthorized charging
