Overview

The prEN ISO 15118-2 standard, titled Road vehicles - Vehicle to grid communication interface - Part 2: Network and application protocol requirements (ISO/DIS 15118-2:2018), defines the network and application layer protocols enabling communication between electric vehicles (EVs) and the electric grid. Developed under the International Organization for Standardization (ISO) and coordinated by CEN, this standard specifies detailed requirements for the interface that facilitates vehicle-to-grid (V2G) integration.

This standard is crucial for establishing interoperable communications that support EV charging and grid services, incorporating key protocols, security measures, and message formats that define how vehicles and charging stations interact efficiently and securely.

Key Topics

• Communication Architecture
  ISO 15118-2 adopts an OSI layered approach defining service primitives and protocols from the data link layer through the application layer. It specifies network layer parameters including IP addressing, TCP, UDP, and transport layer security (TLS) to guarantee data confidentiality and integrity.

• Security Framework
  The standard emphasizes certificate and key management, use of TLS for encryption, and firewall considerations to ensure secure communication between vehicles and charging infrastructure. It details root certificate validity, certificate depth, and protection against unauthorized network access.

• Message and Protocol Specifications
  Extensive message definitions cover V2G handshake protocols, session handling, request-response message sequences, and error handling. The standard supports multiple charging scenarios including alternating current (AC), direct current (DC), wireless power transfer (WPT), bidirectional power transfer (BPT), and automated conductive charging (ACD).

• XML Messaging and Data Types
  Messages use XML and Efficient XML Interchange (EXI) for encoding to optimize communication efficiency. A comprehensive set of schema definitions and complex data types supports standardized information exchange.

• Application Layer Services
  Includes discovery protocols, negotiation of charging parameters, and vehicle authentication mechanisms, such as the e-Mobility Authentication Identifier (EMAID), enabling integration with smart grid functionalities.

Applications

The prEN ISO 15118-2 standard is fundamental for:

• Electric Vehicle Charging Infrastructure
  Ensures seamless interoperability between EVs and charging stations, promoting plug-and-charge capabilities and dynamic charging management.

• Smart Grid Integration
  Enables bidirectional energy flow and communication for load balancing, demand response, and grid stability enhancing renewable energy utilization.

• Vehicle-to-Grid Services
  Supports advanced functionalities such as energy resale, grid support services, and optimized charging schedules based on grid conditions.

• Cybersecurity in E-Mobility
  Provides a robust security framework critical for protecting communication networks and preventing malicious attacks or data breaches in V2G systems.

Standards compliance accelerates market adoption of interoperable and reliable V2G solutions, supporting the global transition to sustainable transport and energy systems.

Introduction
The pending energy crisis and necessity to reduce greenhouse gas emissions started in the former century
has led the vehicle manufacturers to a very significant effort to reduce the energy consumption of their
vehicles up to the present. As countermeasures to this continuous problem, they developed vehicles partly
or completely propelled by electricity power and launched them into the market. Those vehicles will reduce
the dependency on oil, improve the global energy efficiency and reduce the total CO2 emissions for road
transportation if the electricity is produced from renewable sources. To charge electricity to the batteries of
such vehicles, specific charging infrastructure was required.
Much of the standardization work on dimensional and electrical specifications of the charging infrastructure
for electric vehicles and the vehicle interface were treated in the relevant ISO or IEC groups. However, the
standardization work about direct information transfer between the electric vehicle and the charging
infrastructure was not enough, but it was assigned to ISO 15118 series came to be treated sufficiently.
Such communication is necessary for the optimization of energy resources and energy production systems.
With it electric vehicles can be connected to the supply network and communicate the most economic or
most energy efficient way for charging/discharging. It is also required to develop efficient and convenient
billing systems in order to cover the resulting payments. The necessary communication channel may serve
in the future to contribute to the stabilization of the supply network as well as to support additional
information services required to operate electric vehicles efficiently and economically.
After the standardization work of the first basic smart charging was completed, more standardization work for
further evolved functions and high energy efficiency was continuously requested again.
It includes:
* Improved charge methods that reduces efforts and agonies of the charging operation,
* Extended functions for the electric vehicles to be utilized as distributed energy resources (enables
smoothing of the electricity load of the supply network for higher energy efficiency, and also provide power
back to the grid (e.g. for grid services or acting as a standalone power supply as an emergency lifeline),
* Information services for the user with higher added value and new convenience.

As for the communication system, the next evolution will be expected to realize these new applications.

Road vehicles — Vehicle to grid communication interface —
Part 2: Network and application protocol requirements
1 Scope
This international standard specifies the communication between the electric vehicle (EV), including battery
electric vehicle (BEV) and plug-in hybrid electric vehicle (PHEV), and the EV supply equipment. The
application layer message sets defined in this revision of ISO 15118-2 are designed to support the electricity
power transfer between an EV and an EV supply equipment.
The bidirectional electricity power transfer, use case of that was already included in edition 1.0 of part 1 but
not included in part 2, was officially added to the scope of this standard. Herein edition 2.0 of part 2 defines
the communication messages and sequence requirements for bidirectional power transfer.
Also the scope is widely extended in this revision, requirements of wireless communication for both conductive
charging and wireless charging are defined. Additionally, requirements of communication for automatic
connection device and information services about charging and control status are defined in this revision.
The purpose of this part 2 of ISO 15118 is to detail the communication between an electric vehicle
communication controller (EVCC) and supply equipment communication controller (SECC). Aspects are
specified to detect a vehicle in a communication network and enable an Internet Protocol (IP) based
communication between EVCC and SECC.

TCP and IPv6. These requirements belong to the area of from 3rd to 7th OSI layer model. In addition the
document describes main service sequences of conductive charging, wireless power transfer and bidirectional
power transfer, and how data link layer services can be accessed from a layer 3 perspective. The data link
layer and physical layer functionality for wired communication is described in part 3 of this standard, and those
of wireless communication are described in part 8 of this standard.
