Full title and description

BS EN ISO 15118-3:2016 — Road vehicles — Vehicle to grid communication interface — Part 3: Physical and data link layer requirements. This document specifies the physical-layer and data-link-layer requirements for wired high-level communication between electric vehicles (BEV/PHEV) and Electric Vehicle Supply Equipment (EVSE), including signalling, timing, EMC and layer‑2 interfaces needed to support higher-level Vehicle-to-Grid (V2G) services.

Abstract

ISO 15118‑3 defines the low-level communication stack enabling reliable wired communication between vehicle and charging station for conductive charging (in support of IEC charging modes). It covers system architecture mapping to OSI layers, connection coordination (plug‑in, initialization, sleep/wake, loss of communication, plug‑out), timing constants, EMC and signal coupling, layer‑2 service access points, and profiles for powerline communication such as HomePlug Green PHY (normative annex) and an informative annex on IEEE 1901.2 G3‑PLC profiling.

Scope

This part of the ISO 15118 series specifies the requirements of the physical layer and data link layer for a high‑level communication directly between battery electric vehicles (BEV) or plug‑in hybrid electric vehicles (PHEV) and fixed charging installations (EVSE). It applies to manually connected conductive charging (supporting IEC charging modes that allow high‑level communication) and defines the low‑layer architecture, signalling on the control pilot and/or powerline, EMC requirements, timing and interaction procedures required to establish and maintain a robust link for higher‑level V2G services.

Key topics and requirements

• Physical-layer requirements for wired V2G links, including coupling and signal considerations for control‑pilot and powerline communications.
• Data link layer definitions, framing, addressing and layer‑2 service access points for higher-layer protocols.
• System architecture and OSI mapping for EV–EVSE communication modules and identifications.
• Connection coordination procedures: plug‑in, initialization, matching, sleep/wake, loss of communication and plug‑out sequences.
• Timing parameters and protocol constants governing link setup, retries and state transitions.
• Electromagnetic compatibility (EMC) requirements and recommended signal coupling approaches to ensure reliable operation in EV charging environments.
• Normative annex specifying HomePlug Green PHY over the control pilot line; informative annex on IEEE 1901.2 G3‑PLC profiling.
• Interoperability and matching rules to discover compatible low‑layer modules and form logical networks for charging sessions.

Typical use and users

Used by automotive OEMs, EVSE (charging station) manufacturers, chipset and PLC module vendors, test laboratories, certification bodies, systems integrators and national standards organizations. Engineers implementing vehicle‑side or EVSE‑side communication stacks, interoperability testers and compliance assessors rely on this document when designing, developing and validating physical and data‑link layer behaviour for wired EV charging systems.

FAQ

Q: What is this standard?

A: It is Part 3 of the ISO 15118 series, specifying physical and data link layer requirements for wired vehicle‑to‑grid communications between electric vehicles and charging stations; published by ISO (ISO 15118‑3:2015) and adopted as EN ISO 15118‑3:2016 (and published by national bodies such as BSI as BS EN ISO 15118‑3:2016).

Q: What does it cover?

A: It covers low‑level communication architecture and interfaces (physical and link layers), timing and state machines for connection coordination, EMC and signal coupling requirements, layer‑2 service access points, and PLC profiling (including a normative HomePlug Green PHY annex and informative G3‑PLC annex).

Q: Who typically uses it?

A: Vehicle manufacturers, charging station vendors, chipset and PLC module suppliers, test labs and certification bodies, systems integrators and standards professionals working on EV charging communications and interoperability.

Q: Is it current or superseded?

A: ISO 15118‑3:2015 (adopted as EN ISO 15118‑3:2016) remains the authoritative document for the physical and data link layer as published. Users should check national standards bodies and the ISO catalogue for any amendments, corrigenda or later editions; other parts of the ISO 15118 series (and newer parts) address higher‑level protocols and additional features introduced after 2015.

Q: Is it part of a series?

A: Yes — it is Part 3 of the ISO 15118 family (Road vehicles — Vehicle to grid communication interface). Other parts include general information/use cases (Part 1), network and application protocols (Part 2), and later parts that expand messages, security and new use cases.

Q: What are the key keywords?

A: Vehicle‑to‑grid (V2G), EVSE, EV communication, physical layer, data link layer, HomePlug Green PHY, G3‑PLC, control pilot, conductive charging, interoperability, EMC.
