vehicle charging systems
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.
International Standard IEC 61851-21-2 has been prepared by IEC technical committee 69:
Electric road vehicles and electric industrial trucks.
This first edition, together with IEC 61851-21-1, cancels and replaces IEC 61851-21:2001. It
constitutes a technical revision.
This edition includes the following significant technical changes with respect to
IEC 61851-21:2001:
a) this document addresses now only EMC related tests instead of other electrical tests;
b) Clauses 2 and 3 have been updated;
c) the port definition, the test-setups and their corresponding limits as well as the operation
modes are defined more precisely;

ELECTRIC VEHICLE CONDUCTIVE CHARGING SYSTEM –

Part 21-2: Electric vehicle requirements for conductive connection to
an AC/DC supply – EMC requirements for off-board electric
vehicle charging systems
1 Scope
This part of IEC 61851 defines the EMC requirements for any off-board components or
equipment of such systems used to supply or charge electric vehicles with electric power by
conductive power transfer (CPT), with a rated input voltage, according to IEC 60038:2009, up
to 1 000 V AC or 1 500 V DC and an output voltage up to 1 000 V AC or 1 500 V DC.
This document covers off-board charging equipment for mode 1, mode 2, mode 3 and mode 4
charging as defined in IEC 61851-1:2017.
Cables where there is no electronics or no electric/electronic switching are considered as
passive (benign) and are deemed to comply with the emission and immunity requirements of
this document without any need for testing.
This document does not apply to any on-board components or equipment of charging or
power supply systems being part of the vehicles. The EMC requirements for such equipment

are covered by IEC 61851-21-1: 2017.
Compliance with the emission and immunity requirements of this document is verified where it
can be demonstrated that the equipment under test (EUT) meets the respective limits, during
type tests in the measuring arrangement of this document.
Requirements for electric vehicle wireless power transfer (WPT) systems are covered in
IEC 61980 (all parts).

4 Test plan
4.1 General
An EMC test plan shall be established prior to testing. It shall contain, as a minimum, the
elements given in Clause 4.
4.2 Configuration of EUT
All tests shall be carried out using a representative EUT and charge cable (at the conductive
power transfer port – CPT port) to the AE/vehicle simulator as supplied by the manufacturer.
Where the charge cable is not provided with the EUT (e.g. case B according to
IEC 61851-1:2017), tests shall be performed with a typical length and geometry of the charge
cable.
The contents of the standards referenced in this document are not repeated here; however
modifications or additional information needed for practical application of the measurements
of EUT’s is given in this document.

– 12 – IEC 61851-21-2:2018 © IEC 2018
The tests shall be carried out within the specified operating range of the EUT and at its rated
supply voltage.
Test setups according to Annex A shall be used for the immunity and emission tests above
150 kHz.
In-cable control and protection devices (IC-CPDs), other portable equipment and mode 2
equipment shall be tested as per table top equipment.
4.3 Termination of the EUT during testing
All ports of the EUT shall be terminated with ANs/ISN or respectively CDNs as appropriate.
The power input port, signal control port and wired network port shall be terminated according
to Annex C.
The CPT port of the EUT shall be connected to the associated equipment (AE) covering the
artificial networks (ANs) and/or impedance stabilization networks (ISNs) according to Annex C
forming the vehicle simulator and connecting to an appropriate load.
The signalling/control lines of the CPT port shall be terminated according to Annex C and
provide communication by respective simulation and fed in via suitable coupling devices.
4.4 Operating and test conditions
4.4.1 General
The following measurements and assessments may be performed in any order.
4.4.2 Immunity
The immunity requirements are specified in Table 1, Table 2, Table 3 and Table 4 according
to the type of power input (AC or DC) and environmental classification (residential or non-
residential) of the EUT to be tested.
Testing shall be performed in the following two operating modes:
• waiting mode: to simulate when the EUT is fully powered up and connected to a vehicle
but not charging (for example, when the batteries are fully charged or if waiting for the
power grid to decide when to charge);
• charge mode: during testing, the EUT shall be operated at 20 % of the maximum rated
power ±10 %. If this is not possible according to IEC 61851-1:2017, the percentage may
be raised.
It has been considered that no assessment is required when no load is connected since
waiting mode adequately addresses this mode of operation.
In-cable control and protection devices (IC-CPD) shall be tested as off-board AC charging
equipment.
The mode of operation shall be specified and the actual conditions, during the tests, shall be
precisely noted in the test report.
4.4.3 Emissions
Emission requirements are specified in Table 7 to Table 14 and Table 16 to Table 19.
Testing shall be performed in the following operating modes:

IEC 61851-21-2:2018 © IEC 2018 – 13 –
• 20 % of maximum rated power ±10 % (if this is not possible according to
IEC 61851-1:2017 the percentage may be raised); and
• 80 % of maximum rated power ±10 %; or
• with any load allowing the operation of the electrical vehicle supply equipment (EVSE), if
the power input and output are directly connected in charge mode (mode 2 and mode 3
EVSE using mechanical switching devices). In this special case, testing with 20 % and
80 % is not necessary.
For low frequency phenomena (Table 5), tests shall be performed in accordance with the
applicable product family standards (IEC 61000-3-X series).
The operating mode for testing according to 6.2.3 shall be one complete charge cycle with all
outlets.
During the test time, all power output ports (CPT ports) shall be controlled according to the
procedure described here:
• the single outlets/CPT ports shall be started/set in charge mode one by one (sequentially);
• all outlets/CPT ports shall be operated in c
