Information
Definition
ISO 15118-4 contains conformance test specifications for ISO 15118 network and application protocol requirements. On EVCP Info, it links related terminology to the relevant regulatory, standards or compliance framework used by UK-focused audiences.
Why it matters
It helps manufacturers and test bodies assess whether EVs and chargers correctly implement communication behaviour. 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.
