Description (English):

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.

Abstract

Overview

EN ISO 15118-2:2016 (ISO 15118-2:2014) specifies the network and application protocol requirements for Vehicle-to-Grid (V2G) communication between electric vehicles (BEV/PHEV) and Electric Vehicle Supply Equipment (EVSE). The standard defines how an Internet Protocol (IP)-based session is established and managed between the EVCC (Electric Vehicle Communication Controller) and the SECC (Supply Equipment Communication Controller) to support energy transfer from an EVSE to an EV. It focuses on message definitions, data models and data representation formats critical to smart charging, secure authentication and transaction handling.

Key Topics

Application layer message set for EV ↔ EVSE communications designed to support energy transfer (EV charge management).
Data representation using XML and Efficient XML Interchange (EXI).
Network protocols usage: IPv6, TCP, TLS for secure transport and V2G Transfer Protocol (V2GTP).
Security & certificates: TLS-based protection, certificate profiles and annexes covering certificate application.
OSI layered approach: how data link services are accessed from Layer 3; Data Link and Physical Layer details are covered in ISO 15118-3.
Protocol elements and schemas: formal message schemas, message sequencing, error handling, timing requirements and example message sequences.
Informative and normative annexes: protocol schema, message examples, certificate profiles and identifier specifications that support implementation.

Applications

Smart charging systems: enabling secure, standardized exchange of charging parameters, schedules and pricing information between EVs and charging stations.
Billing and authentication: supporting credential exchange and transaction verification for micro-payments and billing.
Grid-integrated EV services: enabling load management and future V2G services such as demand response or vehicle-to-home/grid (note: bidirectional use cases are introduced in ISO 15118‑1 and require application-layer enhancements beyond Part 2).
Interoperability testing: forming the basis for conformance tests between OEMs, EVSE manufacturers and charging network operators.

Who uses this standard

Automotive OEMs (EV communications stack implementers)
EVSE manufacturers and charging infrastructure vendors
EV software developers (EVCC/SECC firmware and backend systems)
Charging network operators, utilities and grid operators
Test labs and certification bodies validating interoperability and security

Related Standards

ISO 15118-1 - General information and use-case definitions (includes bidirectional energy use cases)
ISO 15118-3 - Physical and Data Link Layer requirements
IEC 61851-1 - Electric vehicle conductive charging system general requirements
Other normative references such as ISO 3166-1 for country codes

EN ISO 15118-2:2016 is essential for anyone implementing secure, IP-based EV charging communication and for ensuring interoperable, future-proof V2G services.
