ISO 15118 VAS “InternetAccess” (ServiceID 3)
ISO 15118 Value Added Service that allows the EV and EVSE to use standard internet protocols (e.g., HTTP/HTTPS) during a charging session.
Technical Details
ISO 15118-2 defines optional Value Added Services (VAS). The “InternetAccess” VAS (ServiceID 3) enables protocol use such as HTTP/HTTPS/FTP over the ISO 15118 communication channel. It must be supported and understood by both the EV and EVSE, and is used by VDV 261 to run backend communication (V2ICP) over HTTPS.
Fleet Applications
Provides a standardized way for e-buses to reach depot backends during charging for dispatch-driven services, reducing the need for proprietary vehicle connectivity paths to enable preconditioning and readiness workflows.
