Overview

EN IEC 63110-1:2022 (IEC 63110-1) defines the foundational protocol for management of electric vehicle (EV) charging and discharging infrastructures. As Part 1 of the IEC 63110 series, it provides basic definitions, actor and system architectures, and a comprehensive set of use cases that form the basis for implementing an e‑mobility ecosystem. The standard addresses communication and data flows between e‑mobility actors and the electric power system, covering charging sessions, grid interaction, asset management and cybersecurity.

Key topics and technical requirements

• Definitions & architecture: Actors, roles, domains and an IEC 63110 metamodel to describe interactions between Charge Point Operators (CPOs), Charging Station Management Systems (CSMS), Grid/DSO entities and e‑mobility service providers.
• Use cases: Extensive scenarios including smart charging, demand response, V2G (vehicle-to-grid) sessions, reservation, authorization, roaming and tariff notification.
• Energy transfer & reporting: Management of charging/discharging sessions, required-energy information, grid usage, contractual and metering data.
• EVSE (charging station) asset management: Controlling, monitoring, provisioning, firmware updates, configuration profiles, onboarding/migration and fault/log management.
• Authentication, authorization & payment: Support for credentials, roaming, pricing models and metering information exchanges.
• Cybersecurity & safety: Threat analysis, security requirements for information exchange and relation to use cases (certificate provisioning, OCSP, secure transport).
• Communication protocol & transport requirements (Annex B): IP-based transport (IPv4/IPv6 recommended), support for bidirectional communication, encrypted transport layers, timeouts and ability to carry signed/encrypted payload sub-elements.
• Implementation guidance: Informative annexes provide implementation examples (home, parking, high‑power sites) and criteria for selecting transport technologies.

Applications and who uses it

EN IEC 63110-1 is intended for organizations building, operating or regulating EV charging ecosystems:

• Charge Point Operators (CPOs) and CSMS vendors implementing management and control systems.
• EV Service Providers (eMSPs) and roaming platforms for authorization and billing integration.
• Distribution System Operators (DSOs) and utilities for grid-aware charging, demand response and V2G coordination.
• System integrators and software developers designing communication stacks and secure interfaces.
• Policy makers and standards implementers ensuring interoperability between EVSE, vehicles (ISO 15118) and energy systems.

Related standards

EN IEC 63110-1 references and complements standards such as ISO 15118 (V2G / vehicle-grid communication), IEC 61851 (charging systems), IEC 61850, IEC 63119 (roaming) and relevant IEC/CENELEC grid and security standards - useful for cross‑reference when implementing interoperable, secure e‑mobility solutions.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

INTRODUCTION
In recent years, the necessity of reducing greenhouse gas emissions has led the automotive
industry to develop vehicles propelled by electric energy. Among them, the success of vehicles
with electric rechargeable batteries has marked the beginning of the deployment of electric
charging infrastructures.
During the first years, solutions for management of charging infrastructures were based on
industry alliance specifications or proprietary protocols. They greatly contributed to education
and involvement of early EV adopters. However, with the coming mass development of
e-mobility required by the latest energy policies in most countries, it is necessary to standardize
the communication protocol between charging infrastructures and charging stations operators
in order to establish an international, safe, secure, interoperable and grid friendly e-mobility
eco-system.
This standardized protocol is beneficial to all actors belonging to the e-mobility environment
such as EV manufacturers, charging station manufacturers and operators, e-mobility service
providers, grid network operators, distribution system operators (DSO) and transmission system
operators (TSO), flexibility operators (FO), balance responsible parties and of course the EV
users.
Special attention is paid to the security and traceability of the transactions with respect to
identification and payment, but also to privacy regulations in force in many countries in order to
avoid malicious or criminal use of the charging station.
The general requirements and definitions of this document form the basic framework for all use
case descriptions and related documents in IEC 63110 (all parts). This document is the result
of a large consensus among all the actors of e-mobility and should be considered as a guideline
for implementers of IEC 63110 (all parts).
Technical specifications and requirements of the IEC 63110 protocol will be defined in a future
part of IEC 63110.

Part 1: Basic definitions, use cases and architectures

1 Scope
This part of IEC 63110, as a basis for the other parts of IEC 63110, covers the definitions, use
cases and architecture for the management of electric vehicle charging and discharging
infrastructures.
It addresses the general requirements for the establishment of an e-mobility eco-system,
therefore covering the communication flows between different e-mobility actors as well as data
flows with the electric power system.
This document covers the following features:
– management of energy transfer (e.g., charging session), reporting, including information
exchanges related to the required energy, grid usage, contractual data, and metering data;
– asset management of EVSE, including controlling, monitoring, maintaining, provisioning,
firmware update and configuration (profiles) of EVSE;
– authentication/authorization/payment of charging and discharging sessions, including
roaming, pricing, and metering information;
– the provision of other e-mobility services;
– cybersecurity.
