Road vehicles - Vehicle to grid communication interface - Part 8: Physical layer and data link layer requirements for wireless communication (ISO 15118-8:2020)

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.

Véhicules routiers - Interface de communication entre véhicule et réseau électrique - Partie 8: Exigences relatives à la couche physique et à la couche de liaison entre les données pour la communication sans fil (ISO 15118-8:2020)

Le présent document définit les exigences de la couche physique et de la couche de liaison de données d'une communication sans fil de haute niveau (HLC) entre les véhicules électriques (VE) et les équipements d'alimentation des véhicules électriques (EVSE). La technologie de communication sans fil est utilisée comme alternative à la technologie de communication filaire telle que définie dans l'ISO 15118-3.
Il couvre l'échange global d'information entre tous les acteurs impliqués dans l'échange d'énergie électrique. L'ISO 15118 (toutes les parties) s'applique à la charge par conduction ainsi qu'au transfert d'énergie sans fil (WPT).
Concernant la charge conductive, seuls les EVSE conformes à «l'IEC 61851-1 modes 3 et 4» et supportant la HLC sont couverts par le présent document. Concernant le WPT, les sites de charge conformes à l'IEC 61980 (toutes les parties) et les véhicules conformes à l'ISO 19363 sont traités dans le présent document.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
