INTRODUCTION
The high share of renewable energy sources (RES) connected to the grid, because of their
intermittent and not-programmable nature, imposes a change in the management of the
electrical network.
The replacement of conventional generators with the RES static power converters reduces the
total rotating inertia connected to grid.
An increasing number of distributed energy resources (DERs), consisting in small generators,
energy storage systems and controllable loads, is connected to the distribution networks, which
become "active", that is, capable not only of absorbing energy from the transmission network,
but also of supplying energy in the opposite direction.
The transition to an "All Electric Society", which involves the use of electric energy in the
transportation (e-mobility) and in the building heating and conditioning systems (heat pumps),
increases the demand of electricity and imposes additional stress on the existing electrical
power systems.
Power unbalances, network congestions and voltage fluctuations may happen more frequently.
A more suitable way to manage the electrical network and to dispatch the energy resources is
unavoidable to meet these changes.
The energy flexibility, which is the ability to adjust power generation and/or demand, represents
a solution and it is applicable to DERs.
The growth of electric vehicle (EV) circulation, associated with the expansion of the EV charging
infrastructure and the advent of smart charging (V1G) and vehicle to grid (V2G) technologies
are creating a large number of DERs in the mobility sector.
In fact, the pair EVSE-EV can be considered as a DER, since it can operate as a generator in
V2G mode and as a controllable load in smart charging (V1G). Furthermore, the EV battery is
a mobile energy storage system.
Distributed energy storage systems (DESS), based on electrically chargeable vehicle batteries
(ECV-DESS), can be created by aggregating several EVs connected to the charging
infrastructure and acting as DERs.
The ECV-DESS may provide energy flexibility services contributing to an improvement of the
stable and reliable operation of the electrical network. See Annex C.
The power balancing will result from the coordinated efforts of conventional power systems in
combination with the EV charging infrastructure, other DERs, microgrids and virtual power
plants (VPPs), which may include DESS.
The energy flexibility services are aimed at achieving:
– power balancing;
– network congestion management;
– voltage control.
The specific nature of EV, which is mobile and capable to connect to the charging infrastructure
in different locations, with different charging modes, sets new requirements on the control and
communication interfaces.
IEC 63382-1:2025 © IEC 2025
The EV charging Stations may have different configurations and modes of operations.
They can operate by AC or DC charge, they can charge and discharge, with mono or
bidirectional power transfer between EV and EVSE.
They can be composed by one or more EVSEs in one EV-charging station. In presence of
multiple EVSEs, they can be arranged in AC or DC bus configurations.
Finally, the bidirectional inverter can be installed on-board of vehicle or off-board.
Appropriate standards are essential to manage the complexity of these systems.
These standards will sustain the growth of EV circulation, rule the V1G and V2G services,
support the aggregation of multiple EV DERs, define how to specify the requirements between
the aggregator /flexibility operator (FO) and the EV charging station operators.
NOTE Aggregator and flexibility operator have the same meaning in the context of this document.
The presence in the e-mobility market of products and services offered by several vendors calls
for interoperability and interchangeability between solutions provided by different suppliers.
Furthermore, the standards have to meet the requirements of cybersecurity and privacy for a
proper operation of ECV DESSs.
The IEC 63382 series is intended to cover all these aspects and to fills gaps in existing
standards concerning communication between the aggregator/FO and the EV charging station
backend system.
It is aimed at completing the communication and control chain which connect the EV with the
charging infrastructure (EVSE and charging stations) and with the aggregator/FO at an upper
hierarchical level. In this respect it represents a complement of the standardization work made
on ISO 15118 series and IEC 63110 series.
The IEC 63382 series consists of three parts, each dedicated to a specific subject:
IEC 63382-1 is dedicated to EV charging station configurations, communication architecture,
requirements, both functional and non-functional, use cases, with actors, roles and domains
descriptions. Reference is made to CENELEC's SGAM (Smart Grid Architecture Model) and to
UML model.
IEC 63382-2 is dedicated to communication protocol specifications. It includes layered model
according to OSI model from ISO, list of requirements, data models, object model, messages
and message formats, datatypes, message sequences, and security aspects.
IEC 63382-3 is dedicated to conformance testing. The tests will cover the interface between
Aggregator/FO and the CS Backend system.
It includes test setup, test suite, test cases designed to verify behaviour of system with respect
to specifications and requirements.
The IEC 63382 series is intended to be used by the many stakeholders of ECV-DESS:
Aggregators/FO, e-mobility service providers, car makers, utilities (e.g. energy supplier
(reseller), transmission grid operator (TSO), distribution grid operator (DSO), measuring point
operator), EV users, EV charging station operators and owners, manufacturers and maintainers
of interfacing products, technology providers (HW, SW, certification testing), software
developers and system engineers.

1 Scope
The IEC 63382 series specifies the management of distributed energy storage systems,
composed of electrically chargeable vehicle batteries (ECV-DESS), which are handled by an
aggregator/flexibility operator (FO) to provide energy flexibility services to grid operators.
Aggregator and flexibility operator have the same meaning in the context of this document and
represent the entity which aggregates a number of other network users (e.g. energy consumers,
prosumers, DERs) bundling energy consumption or generation assets into manageable sizes
for the energy system.
The aggregator/FO communicates with the charging station (CS) backend system, which is
typically the system platform (HW, SW and HMI) of either a charging station operator (CSO), or
a charging service provider (CSP).
The purpose of the data exchange is to perform flexibility services, and it takes place between
the aggregator/FO and a dedicated interface located in the CS backend system, which has
been defined FCSBE, flexibility port at the charging station backend.
This part of IEC 63382 describes the technical characteristics and architectures of ECV-DESS,
including:
– EV charging stations configurations, comprising several AC-EVSEs and/or DC-EVSEs;
– individual EVs connected to grid via an EVSE and managed by an aggregator/FO.
The focus of this document is on the interface between the FO and the FCSBE and the data
exchange at this interface, necessary to perform energy flexibility services (FS).
The FO/aggregator converts grid services and/or grid support functions requested by the grid
operators (DSOs or TSOs) into multiple flexibility services to be provided by a number of CSs,
utilizing their own optimization and resource allocation algorithms.
Communication between FO and grid operators (DSO, TSO), optimization algorithms adopted
by FO, flexibility service bidding procedures are out of scope of this document.
The data exchange between FO and FCSBE typically includes:
– flexibility service request and response;
– flexibility services parameters;
– EV charging station configuration and technical capabilities;
– credentials check of parties involved in the flexibility service;
– FS execution related notifications;
– event log, detailed service record, proof of work.
The exchange of credentials has the purpose to identify, authenticate and authorize the actors
involved in the flexibility service transaction, to check the validity of a FS contract and to verify
the technical capabilities of the system EV + CS, and conformity to applicable technical
standards to provide the requested flexibility service.
This document also describes the technical requirements of ECV-DESS, the use cases, the
information exchange between the EV charging station operator (CSO) and the aggregator/FO,

It covers many aspects associated to the operation of ECV-DESS, including:
– privacy issues consequent to GDPR application (general data protection regulation);
– cybersecurity issues;
– grid code requirements, as set in national guidelines, to include ancillary services,
mandatory functions and remunerated services;
– grid functions associated to V2G operation, including new services, as fast frequency
response;
– authentication/authorization/transactions relative to charging sessions, including roaming,
pricing and metering information;
– management of energy transfers and reporting, including information interchange, related
to power/energy exchange, contractual data, metering data;
– demand response, as smart charging (V1G).
It makes a distinction between mandatory grid functions and market driven services, taking into
account the functions which are embedded in the FW control of DER smart inverters.
This document deals with use cases, requirements and architectures of the ECV-DESSs with
the associated EV charging stations.
Some classes of energy flexibility services (FS) have been identified and illustrated in dedicated
use cases:
– following a dynamic setpoint from FO;
– automatic execution of a droop curve provided by FO, according to local measurements of
frequency, voltage and power;
– demand response tasks, stimulated by price signals from FO;
– fast frequency response.
Furthermore, some other more specific flexibility service use cases include:
– V2G for tertiary control with reserve market;
– V2H with dynamic pricing linked to the wholesale market price;
– distribution grid congestion by EV charging and discharging.
FS are performed under flexibility service contracts (FSC) which can be stipulated between:
– FO and EV owner (EVU or EV fleet manager);
– FO and CSP;
– FO and CSO.
Any flexibility service is requested by the aggregator/FO with a flexibility service request (FSR)
communicated through the FCSBE interface to the available resources.
The actors EVU, CSO, CSP have always the right to choose opt-in or opt-out options in case
of a FSR, unless it is mandatory for safety or grid stability reasons.
A use case shows how to discover flexibility service contract (FSC) holders.
This document describes many use cases, some of them are dedicated to special applications
such as as: EV service station, energy community, fast frequency response, EV fleet, onboard
bidirectional inverter, mobile app.
