Full title and description

Road vehicles — Vehicle to grid communication interface — Part 8: Physical layer and data link layer requirements for wireless communication. This ISO standard defines the physical‑layer and data‑link‑layer requirements for a wireless High Level Communication (HLC) between an electric vehicle (EV) and the electric vehicle supply equipment (EVSE), as an alternative to the wired communication specified elsewhere in the ISO 15118 family.

Abstract

This document specifies requirements for the physical and data link layers of wireless HLC between EV and EVSE. It covers information exchange for both conductive charging (where applicable to IEC 61851‑1 modes 3 and 4) and Wireless Power Transfer (WPT) charging sites (referencing IEC 61980 and vehicle requirements such as ISO 19363). The wireless technology is intended as an alternative to the wired physical/data link definitions in ISO 15118‑3.

Scope

Specifies the physical‑ and data‑link‑layer requirements for wireless High Level Communication (HLC) between EV and EVSE. The scope includes wireless communication as an alternative to the wired physical/data‑link defined in ISO 15118‑3, and addresses applicability for conductive charging systems (limited to EVSEs compliant with IEC 61851‑1 modes 3 and 4 that support HLC) as well as Wireless Power Transfer (WPT) environments (referencing IEC 61980 and ISO 19363 for vehicle interfaces). The standard is intended to enable interoperable, reliable wireless link-layer communications for EV charging and related energy exchange functions.

Key topics and requirements

• Physical‑layer requirements for wireless EV↔EVSE communication (signal framing, modulation / link characteristics and interface constraints appropriate for WPT and wireless charging scenarios).
• Data‑link‑layer requirements (frame formats, addressing, link establishment, error handling and timing to support HLC message transport).
• Interoperability considerations for wireless HLC in both conductive and wireless charging contexts.
• Normative references to related charging and wireless standards (for example IEC 61851‑1 for conductive charging modes, IEC 61980 for WPT and ISO 19363 for vehicle WPT interfaces).
• Conformance relationship to the ISO 15118 test parts (wireless conformance tests are addressed in companion parts of the series).

Typical use and users

Primary users include EV OEMs, EVSE (charging station) manufacturers, wireless charging system designers, test and certification laboratories, system integrators, and standards/compatibility engineers responsible for implementing or validating wireless EV charging communications. Operators of charging infrastructure and utilities involved in advanced charging services may also reference the standard for interoperability and system design.
