168 FOREWORD
170 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
171 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
172 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
173 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
174 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
175 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
176 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
177 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
178 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
179 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
180 consensus of opinion on the relevant subjects since each technical committee has representation from all
181 interested IEC National Committees.
182 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
183 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
184 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
185 misinterpretation by any end user.
186 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
187 transparently to the maximum extent possible in their national and regional publications. Any divergence between
188 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
189 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
190 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
191 services carried out by independent certification bodies.
192 6) All users should ensure that they have the latest edition of this publication.
193 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
194 members of its technical committees and IEC National Committees for any personal injury, property damage or
195 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
196 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
197 Publications.
198 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
199 indispensable for the correct application of this publication.
200 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
201 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
202 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which

229 INTRODUCTION
232 An increasing number of DERs are being interconnected to electrical power systems while
233 control and communication standards provide interoperable interfaces between DERs and other
234 actors involved in the needed exchange of information. The growth of electric vehicle (EV)
235 circulation, associated with the expansion of the charging infrastructure and the advent of Smart
236 Charging (V1G) and Vehicle to Grid (V2G) technologies are creating a large number of DERs
237 in the mobility sector.
238 Distributed Energy Storage Systems, based on Electrically Chargeable Vehicle batteries (ECV-
239 DESS), can be created by aggregating several EVs connected to the charging infrastructure
240 and acting as DERs. The ECV-DESS may provide grid services to improve the stable and
241 reliable operation of the electrical power network. The Power Balancing will result from the
242 coordinated efforts of conventional power systems in combination with the EV Charging
243 infrastructure, the microgrids, the Virtual Power Plants, which will include DESS.
244 The specific nature of EV, which is a mobile DER, capable to connect to the charging
245 infrastructure in different locations, with different charging modes, sets new requirements on
246 communication interfaces. For instance, the EV Charging Stations may have different
247 configurations and modes of operations. They can operate by AC or DC charge, they can charge
248 and discharge, with mono or bidirectional power flow between EV and EVSE. They can be
249 composed by one or more EVSEs in one EV-Charging Station. In presence of multiple EVSEs,
250 they can be arranged in AC or DC bus configurations. Finally, the bidirectional inverter can be
251 installed on-board of vehicle or off board.
252 Appropriate standards are essential to rule the complexity of these systems. These standards
253 will sustain the growth of EV circulation, rule the V1G and V2X services, support the aggregation
254 of multiple EV DERs, define how to specify the requirements between Aggregator/Flexibility
255 Operator (FO) and EV Charging Station Operators. Presence on the market of products and
256 services offered by several vendors calls for interoperability and interchangeability between
257 solutions provided by different suppliers. Furthermore, the standards have to meet the
258 requirements of cybersecurity, privacy and safety for the proper operation of ECV DESSs.

259 IEC 63382 is intended to cover all these aspects and to fills gaps in existing standards
260 concerning communication between Aggregator/FO and EV Charging Station. It is aimed at
261 completing the communication and control chain which connect the EV with the charging
262 infrastructure (EVSE and Charging Stations) and with the Aggregator/FO at an upper
263 hierarchical level. In this respect it represents a complement of the standardization work made
264 on IEC/ISO 15118 and IEC 63110.

266 MANAGEMENT OF DISTRIBUTED ENERGY STORAGE SYSTEMS
267 BASED ON ELECTRICALLY CHARGEABLE VEHICLE BATTERIES
269 Part 1: Use Cases & Architectures
272 1 Scope
273 IEC 63382 specifies the management of Distributed Energy Storage Systems, composed of
274 Electrically Chargeable Vehicle batteries (ECV-DESS), which are managed by an
275 Aggregator/Flexibility Operator (FO) and which are capable of performing Vehicle-to-V1G, V2G
276 and V2X functions. This part 1 addresses the ECV-DESS use cases and architecture.
277 The Distribution System Operator (DSO) determines what distribution grid services are required
278 or optional for distributed energy Resources (DER) to meet, and the Aggregator/FO establishes
279 the technical and business requirements for the EVs to provide those grid services. These grid
280 services can be provided by the Charging Station Operator (CSO) for the EVs connected in the
281 charging station and/or by the individual EV User via their EV permissions and settings.
282 IEC 63382 describes the technical characteristics and requirements of ECV-DESS, including:
283 • EV charging stations configurations, comprised of several AC-EVSEs and/or DC-EVSEs.
284 • Individual EVs connected to grid via an EVSE and managed by an Aggregator/FO.
285 This document also describes the technical requirements of ECV-DESS, the Use Cases, the
286 information exchange between the EV Charging Station Operator (CSO) and the Aggregator/FO,
287 including both technical and business data, the communication protocols, and the conformance
288 tests. It covers many aspects associated to the operation of ECV-DESS, including:
289 • Privacy issues consequent to GDPR application (General Data Protection Regulation).
290 • Cybersecurity issues.
291 • Grid Code requirements, as set in national guidelines, to include ancillary services, mandatory
292 functions and remunerated services.
293 • Grid functions associated to V2G operation, including new services, as fast reserve for
294 frequency regulation.
295 • Authentication/authorisation/transactions relative to charging sessions, including roaming,
296 pricing and metering information.
297 • Management of energy transfers and reporting, including information interchange, related to
298 power/energy exchange, contractual data, metering data.
299 • Demand Response, as smart charging (V1G).
300 It makes a distinction between mandatory functions and market driven services, taking into
301 account the functions which are embedded in the FW control of DER smart inverters.
302 The 3 parts of IEC 63382 are each dedicated to a specific subject:
303 • Part 1 is dedicated to EV charging station configurations, communication architecture,
304 requirements, both functional and non-functional, use cases, with actors, roles and domains
305 descriptions. Reference is made to CENELEC’s SGAM (Smart Grid Architecture Model) and to
306 UML model.
307 • Part 2 is dedicated to communication protocol specifications. it includes layered model
308 according to OSI model from ISO, list of requirements, data models, object model, messages
309 and message formats, datatypes, message sequences, and security aspects.

Internal
oSIST prEN IEC 63382-1:2024
IEC CDV 63382 © IEC 2024 – 10 –
310 • Part 3 is dedicated to Conformance testing. The conformance tests will cover the interface
311 between Aggregator/FO and CSO. It includes Test setup, Test suite, Test cases designed to
312 verify behaviour of system with respect to specifications and requirements.
314 The IEC 63382 standard is intended to be used by the many stakeholders of ECV-DESS:
315 Aggregators/FO, e-mobility service providers, car makers, utilities, EV users, EV charging
316 station operators and owners, manufacturers and maintainers of interfacing products,
317 technology providers (HW, SW, certification testing), software developers and system
318 engineers.
