Information
Definition
ISO 15118-5 contains conformance test specifications for the physical and data link layer of vehicle-to-grid communication. On EVCP Info, it links related terminology to the relevant regulatory, standards or compliance framework used by UK-focused audiences.
Why it matters
It supports reliable interoperability testing where vehicles and chargers must communicate correctly over the physical charging connection. For UK users, it helps separate legal requirements, recognised standards, good practice and manufacturer claims when reviewing EV charging equipment.

ISO 15118
ISO 15118 is the international vehicle-to-grid communication standard series covering EV-to-charger digital communication, Plug & Charge, smart charging and bidirectional charging functions. In the UK it is increasingly relevant to future-ready public, fleet and V2G-capable charging systems.
