Description (English):

This document specifies the requirements of the physical and data link layer of a wireless High Level Communication (HLC) between Electric Vehicles (EV) and the Electric Vehicle Supply Equipment (EVSE). The wireless communication technology is used as an alternative to the wired communication technology as defined in ISO 15118‑3. It covers the overall information exchange between all actors involved in the electrical energy exchange. ISO 15118 (all parts) are applicable for conductive charging as well as Wireless Power Transfer (WPT). For conductive charging, only EVSEs compliant with "IEC 61851‑1 modes 3 and 4" and supporting HLC are covered by this document. For WPT, charging sites according to IEC 61980 (all parts) and vehicles according to ISO 19363 are covered by this document.

Abstract

Overview

EN ISO 15118-8:2020 (ISO 15118-8:2020) defines the physical layer and data link layer requirements for wireless High Level Communication (HLC) between Electric Vehicles (EV) and Electric Vehicle Supply Equipment (EVSE). Part of the ISO 15118 series for vehicle-to-grid (V2G) communication, this standard specifies how wireless technologies can be used as an alternative to the wired HLC defined in ISO 15118-3. It applies to both conductive charging (EVSEs compliant with IEC 61851‑1 modes 3 and 4) and Wireless Power Transfer (WPT) installations (IEC 61980 series and vehicles per ISO 19363). EN ISO 15118-8:2020 supersedes the 2019 edition and contains minor revisions (e.g., DFS/TPC usage updates).

Key Topics

System architecture for wireless HLC between EV and EVSE, including roles and service models.
WLAN technology requirements as the primary wireless medium (physical and MAC layer expectations).
Frequency and channel management, including channel scanning, selection, and national regulation considerations (U‑NII bands).
Dynamic frequency selection (DFS) and transmit power control (TPC) usage and compliance.
Quality of Service (QoS) to ensure reliable message delivery for charging control and V2G services.
Association and pairing mechanisms for establishing secure wireless links between EV and EVSE.
Layer 2 interfaces and interoperability requirements for Ethernet/WLAN bridging at the data link layer.
Security considerations for protecting session establishment, authentication and data integrity.
Informative annexes: antenna mounting guidance, interference scanning and auto‑channel selection examples, service-area definitions, and national band regulations.

Applications

Enabling secure, interoperable wireless communications for EV charging at residential, commercial and public charging sites.
Supporting V2G features such as demand response, grid stabilization and smart charging where wired HLC is not practical.
Implementing wireless power transfer (WPT) scenarios where the physical power interface is contactless and wireless communication is necessary.
Facilitating billing, authentication and energy management interactions between vehicle, charge point operator (CPO) systems, and grid operators.

Who Uses This Standard

EV and EVSE manufacturers (hardware and firmware teams)
Charging station integrators and system architects
Network and cybersecurity engineers for EV infrastructure
Test laboratories and certification bodies validating wireless HLC compliance
Regulators and policy makers addressing national spectrum rules

Related Standards
