▶ Working Principle

The core of the VIN charging system lies in using the vehicle’s VIN as an identification marker, ensuring the security and efficiency of the charging process. The specific workflow is as follows:

1. Vehicle Identification:

  • When a user plugs the charging gun into the electric vehicle’s charging port, the charging pile automatically reads the vehicle’s VIN. This process can be accomplished by uploading a photo of the driving license via an app or by automatically recognizing the VIN after plugging in.

2. Identity Verification:

  • The charging pile compares the read VIN with information in the backend database. If there is a match, the system confirms that the vehicle is a legitimate user and allows charging to begin; if not, it rejects the charging request.

3. Plug-and-Charge:

  • Once identity verification is successful, users do not need to perform any additional operations (such as scanning a code or entering a password), and the charging pile will automatically start charging. This “plug-and-charge” mode greatly simplifies the user’s operational process, enhancing convenience.

4. Data Transmission and Billing:

  • During the charging process, there is continuous data exchange between the charging pile and the vehicle, including information on charging status, power levels, etc. This data is used not only for real-time monitoring but also for subsequent billing and service management.

5. Charging Completion:

  • Users can end the charging session through the app or directly at the charging pile. The system records data from this charging session and generates corresponding billing statements.

▶ Advantages and Features

  • Convenience: Users only need to plug in to start charging without complex operations.
  • Security: Identity verification through VIN effectively prevents unauthorized vehicles from using charging facilities.
  • Efficient Management: Operators can better manage user data and services, providing personalized experiences.
  • Strong Compatibility: This system is applicable to various brands and models of electric vehicles, promoting the widespread adoption of new energy vehicles.

▶ Application Scenarios

The VIN charging technology of State Grid e-Charging is widely applied in both public and private charging piles, especially suitable for frequent users of public facilities, such as ride-hailing drivers. This technology not only enhances user experience but also lays a foundation for the development of future intelligent transportation systems. By continuously optimizing and promoting VIN charging services, State Grid e-Charging is contributing to the advancement of the electric vehicle industry.
