V2ICP (Vehicle to Infrastructure Communication Protocol)
A VDV 261-defined protocol for exchanging operational parameters between an e-bus and a backend system via ISO 15118 Value Added Services.
Technical Details
V2ICP runs over an ISO 15118-secured setup using TLS and IPv6, typically leveraging the ISO 15118 “InternetAccess” Value Added Service for HTTPS communication. It defines request/response behaviors (e.g., sequence handling and non-empty responses) and uses “SNA” placeholder values for unavailable parameters to keep the interface predictable.
Fleet Applications
Enables standardized vehicle↔backend coordination for depot workflows such as readiness checks and preconditioning commands, helping avoid proprietary integrations between buses, chargers, and depot management systems.

ISO 15118 (Plug & Charge)
Family of standards for high-level communication between an electric vehicle (EV) and a charging station (EVSE), enabling certificate-based "Plug & Charge" and advanced charging control (including bidirectional charging in newer editions).
VDV 261 (Dispositive Backend via ISO 15118 VAS)
VDV recommendation that extends ISO 15118 (Ed. 1) for e-bus operations by defining how an e-bus connects to a dispatching (“dispositive”) backend to exchange preparation parameters such as preconditioning.
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.
