What is ISO 15118?

ISO 15118 is a standard that defines the communication protocol between electric vehicles (EVs) and charging infrastructure. It enables secure, reliable, and interoperable communication for EV charging.

Features of ISO 15118

ISO 15118 offers several key features that enhance the charging experience:

Plug and Charge

Plug and Charge simplifies the charging process by enabling automatic authentication and authorization. With this feature, EV owners can directly plug their vehicles into a charging station, and the system will automatically handle the payment, security, and identification without requiring any additional steps from the user.

Bidirectional Power Transfer

Bidirectional Power Transfer allows power to flow not only from the charging station to the vehicle but also in the opposite direction. This means that EVs can act as energy storage devices and feed electricity back to the grid when needed. It opens up opportunities for vehicle-to-grid integration, where EVs can help stabilize the electrical grid by supplying power during peak demand or supporting renewable energy integration.

Data Exchange

Data Exchange capabilities offered by ISO 15118 enable seamless communication between the EV and the charging station. This allows the exchange of information such as battery status, available charging capacity, charging schedules, and energy prices. This data exchange enables smart charging functionalities, optimizing the charging process based on user preferences, grid conditions, and electricity costs.

Privacy and Security

Privacy and Security are essential aspects of ISO 15118. The standard ensures secure authentication and encryption of the communication, protecting sensitive user and vehicle data. It also provides privacy protection by allowing EV owners to control the sharing of their information during the charging process.

Conclusion

ISO 15118 is a crucial standard that streamlines the communication between EVs and charging infrastructure. Its features like Plug and Charge, Bidirectional Power Transfer, Data Exchange, and Privacy and Security contribute to a safer, more efficient, and user-friendly electric vehicle charging ecosystem.
