ISO 15118 is an international standard that specifies the communication interface between electric vehicles and charging infrastructure, thereby enabling a smart, automated, and interoperable electric vehicle charging process.
The full name of the ISO 15118 standard is "ISO 15118 Road vehicles—Vehicle-to-grid communication interface," developed by the International Organization for Standardization (ISO).
The main objectives of the ISO 15118 standard include:
Communication Protocol: Defines the communication protocol and data exchange formats between electric vehicles and charging infrastructure to enable the control, monitoring, and management of the charging process.
Security: Provides a secure and reliable communication method to ensure the security of communications between electric vehicles and charging equipment, preventing data leaks or malicious attacks.
Interoperability: Ensures interoperability between electric vehicles and charging equipment from different manufacturers—that is, they can recognize and be compatible with one another without requiring additional adaptation or adjustments.
Smart Charging: Supports smart charging functions, including dynamic power adjustment, remote start and stop of charging, and payment, to improve charging efficiency and the user experience.
The ISO 15118 standard is regarded as one of the key foundations driving the development of smart charging technology for electric vehicles, providing consistent communication standards and technical specifications for all segments of the electric vehicle industry chain. Adherence to the ISO 15118 standard can accelerate the construction and deployment of electric vehicle charging infrastructure, thereby promoting the widespread adoption and application of electric vehicles.
When implementing and applying the ISO 15118 standard, there are several key points to note:
Compliance Checks: Ensure that the selected electric vehicles and charging infrastructure meet the requirements of the ISO 15118 standard. It is best to select products that have already been certified or tested to ensure they meet the standard’s requirements.
Security: Take care to ensure the security of communication processes, including measures such as data encryption, authentication, and security certification, to prevent data breaches or malicious attacks.
Interoperability: Ensure interoperability between electric vehicles and charging infrastructure from different manufacturers without the need for additional adaptation or adjustment, thereby promoting the coordinated development of the entire industry chain.
Compatibility: Ensure that the selected charging equipment and vehicles support the communication protocols and data formats defined by ISO 15118 to guarantee a smooth charging process.
Smart Charging: Make full use of the smart charging features provided by the ISO 15118 standard—such as dynamic power adjustment, remote start and stop of charging, and payment functions—to improve charging efficiency and the user experience.
System Integration: When designing and constructing electric vehicle charging infrastructure, consider the system integration of all components—including charging equipment, EV charging station management systems, and grid-side management systems—to ensure the stable operation of the entire charging system.
Training and Promotion: Provide training on the ISO 15118 standard to relevant personnel, including EV charging station operations and maintenance staff and vehicle owners, to improve their understanding of the proper use of charging equipment and enhance safety awareness, thereby promoting the widespread adoption of the standard.
