Road vehicles - Vehicle to grid communication interface - Part 2: Network and application protocol requirements (ISO/DIS 15118-2:2018)
ISO 15118-2:2014 specifies the communication between battery electric vehicles (BEV) or plug-in hybrid electric vehicles (PHEV) and the Electric Vehicle Supply Equipment. The application layer message set defined in ISO 15118-2:2014 is designed to support the energy transfer from an EVSE to an EV. ISO 15118-1 contains additional use case elements describing the bidirectional energy transfer. The implementation of these use cases requires enhancements of the application layer message set defined herein.
The purpose of ISO 15118-2:2014 is to detail the communication between an EV (BEV or a PHEV) and an EVSE. Aspects are specified to detect a vehicle in a communication network and enable an Internet Protocol (IP) based communication between EVCC and SECC.
ISO 15118-2:2014 defines messages, data model, XML/EXI based data representation format, usage of V2GTP, TLS, TCP and IPv6. In addition, it describes how data link layer services can be accessed from a layer 3 perspective. The Data Link Layer and Physical Layer functionality is described in ISO 15118-3.

Véhicules routiers - Interface de communication entre véhicule et réseau électrique - Partie 2 : Exigences du protocole d'application et du réseau (ISO/DIS 15118-2:2018)
Le présent document spécifie la communication entre les véhicules électriques à batterie (VEB) ou les véhicules électriques hybrides rechargeables (VEHR) et l'infrastructure de recharge pour véhicules électriques. L'ensemble de messages de la couche application défini dans le présent document est conçu pour prendre en charge le transfert d'énergie entre une IRVE et un VE. L'ISO 15118-1 contient des éléments de cas d'utilisation supplémentaires (ID des éléments de cas d'utilisation de la Partie 1 : F4 et F5) décrivant le transfert d'énergie bidirectionnel. L'implémentation de ces cas d'utilisation nécessite des améliorations de l'ensemble de messages de la couche application défini dans le présent document. Les définitions de ces exigences supplémentaires feront l'objet de la prochaine révision du présent document.
Le présent document a pour but de décrire de manière détaillée la communication entre un VE (VEB ou VEHR) et une IRVE. Les aspects spécifiés permettent de détecter un véhicule dans un réseau de communication, et de permettre une communication basée sur le protocole Internet (IP) entre le contrôleur de communication du véhicule électrique (EVCC) et le contrôleur de communication de l'infrastructure de recharge (SECC).
Le présent document définit les messages, le modèle de données, le format de représentation de données basé sur XML/EXI, l'utilisation de V2GTP, TLS, TCP et IPv6. De plus, il décrit comment accéder aux services de la couche liaison de données à partir de la couche 3. La fonctionnalité de la couche liaison de données et de la couche physique est décrite dans l'ISO 15118-3.
