Features of ISO 15118

ISO 15118 is a comprehensive standard that defines the communication protocol between an Electric Vehicle (EV) and a Charging Station (CS). It enables bi-directional communication, ensuring safe and efficient charging while also providing additional smart features. In this article, we will explore the key features of ISO 15118.

Plug & Charge

One of the standout features of ISO 15118 is "Plug & Charge." This feature allows electric vehicles to automatically authenticate and authorize themselves with the charging station without the need for additional cards or mobile apps. Through digital certificates and secure communication channels, the EV and CS can establish trust and securely exchange information, streamlining the charging process.

Smart Charging

ISO 15118 introduces intelligent charging capabilities, empowering EVs and CSs to communicate and optimize charging parameters based on various factors. Utilizing real-time data such as grid conditions, electricity rates, and user preferences, smart charging ensures the most cost-effective and environmentally friendly charging strategy. It also allows for load management, enabling multiple vehicles to share limited power resources efficiently.

Vehicle-to-Grid (V2G)

Another significant feature of ISO 15118 is Vehicle-to-Grid (V2G) communication. This functionality enables EVs not only to consume energy from the grid but also to supply power back to it when needed. V2G facilitates the integration of renewable energy sources, smooths out peak electricity demands, and provides essential grid services like frequency regulation. ISO 15118 defines the communication protocols and data formats necessary for seamless bidirectional energy flow between EVs and the grid.

In conclusion, ISO 15118 offers several advanced features that optimize the charging process and enhance the capabilities of electric vehicles. "Plug & Charge" simplifies authentication, while smart charging ensures efficient utilization of energy resources. V2G functionality opens up new opportunities for grid stability and renewable energy integration. As the adoption of EVs continues to grow, ISO 15118 plays a crucial role in enabling safe, secure, and intelligent charging infrastructure.
