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
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC TR 61850-90-8, which is a technical report, has been prepared by IEC technical
committee 57: Power systems management and associated information exchange.
The text of this technical report is based on the following documents:

INTRODUCTION
This part of IEC 61850-90, which is a technical report, describes how current standardization
for Electric Road Vehicles (EV) and the Vehicle-to-Grid Communication Interface can be
linked to IEC 61850-7-420, which deals with Distributed Energy Resources (DER). This
technical report provides necessary background information and proposes an object model for
E-Mobility in order to establish an EV plugged into the power grid as DER according to the
principles of IEC 61850-7-420. The basic information modeling in IEC 61850 and
IEC 61850-7-420 already covers a lot of needs for the E-Mobility domain. Missing parts can
be modeled as new logical nodes and data objects, which this technical report defines.
NOTE Editorial Notes on this technical report are summarized in Annex G.

COMMUNICATION NETWORKS AND SYSTEMS
FOR POWER UTILITY AUTOMATION –

Part 90-8: Object model for E-mobility

1 Scope
This part of IEC 61850-90, which is a technical report, shows how IEC 61850-7-420 can be
used to model the essential parts of the E-Mobility standards related to Electric Vehicles and
Electric Vehicle Supply Equipments (IEC 62196, IEC 61851, IEC 15118) and the Power
system (IEC 61850-7-420), in order to secure a high level of safety and interoperability.
The namespace of this document is:
• “(TR) IEC 61850-90-8:2015”
The name space "IEC 61850-90-8" is considered as "Transitional" since the model is
expected to be included in the next edition of IEC 61850-7-420 . Potential
extensions/modifications may happen if/when the model is given International Standard status.
The most optimal backward compatibility with the original content will be strived for during this
move.
In accordance with the status of the ISO 15118 series and systems determined in
IEC 61851-23 and -24, this technical report focuses on EV charging processes only.
Discharging processes in order to support grid services are out of scope, but will be adopted
when available in future versions of ISO 15118-2 and IEC 61851-1, -23 and -24.

the power grid connected to this SECC. Most likely this function will be served by a system operator.
Note 2 to entry: Demand Clearing House and meter operator may exchange information with each other as well
as with other actors.
EXAMPLE A DCH typically fulfils following tasks:
• Collect all necessary information from all parts of the power grid, e.g. current or forecasted load of local trans-
formers, distribution grid, power substation, transmission grid, transmission substation, power plants (incl. re-
newable energies), and predicted charging schedules submitted by EVCCs.A Charging Station represents a
single or multiple EV Supply Equipment(s) (see also EVSE).
• Consolidate the collected grid information to a ―grid profile‖ and offer it to SECCs / EVCCs.
• Provide charging schedule proposal for the connected EV to the requesting SECC based on the collected grid
profile.
• Inform the SECC as to the necessity for an updated charging schedule if the grid profile has changed.
• On the contrary, the SECC will inform the demand clearing house if the EV's charging schedule has changed.
