Overview

IEC 62893-3:2017 is an international standard that specifies requirements for charging cables used for AC charging of electric vehicles (EVs) according to modes 1, 2 and 3 of IEC 61851-1. It covers cables of the IEC 0,6/1 kV family with rated voltages up to and including 450/750 V and sets a maximum conductor operating temperature of 90 °C. Ordinary-duty flexible cables rated 300/500 V are permitted only for charging mode 1.

Key topics and technical requirements

• Scope and cable types: Defines ordinary duty (types 62893 IEC 121, 122) and heavy duty (types 62893 IEC 123, 124, 125) flexible cables for EV AC charging.
• Rated voltages: Cables rated 300/500 V (ordinary duty) and 450/750 V (heavy duty).
• Conductor sizes and construction: Power core sizes include 1.5 mm2 and 2.5 mm2 for ordinary duty; heavy duty covers 1.5 mm2 up to 35 mm2 and 3–5 core constructions; cores are class 5 flexible conductors and are twisted/assembled with non-adhering sheaths.
• Insulation and sheath materials: Insulation compounds (EVI-1, EVI-2) and halogen-free sheath compounds (EVM-1, EVM-2, EVM-3) are specified by cable type; sheath must not adhere to cores.
• Marking and dimensioning: Marking requirements refer to IEC 62893-1; dimensional and insulation thickness data are provided in Annex B tables.
• Testing and verification: Test methods and performance requirements reference IEC 62893-2, IEC 60245-2, IEC 60332-1-2, IEC 62821-1 and relevant IEC 60811 parts. Annex A lists tests for completed cables (compatibility, cold impact, crush resistance, fire performance, etc.).
• Use guidance: Clause 5 refers to IEC 62440 for safe use and includes tables for intended environmental and duty conditions.

Applications and who uses this standard

• Cable manufacturers designing and producing EV charging cables for AC charging (modes 1–3).
• EVSE (Electric Vehicle Supply Equipment) OEMs specifying compatible charging leads and assemblies.
• Test laboratories and conformity assessors performing required tests per Annex A and referenced documents.

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.

1 Scope
This part of IEC 62893 applies to cables for AC charging according to modes 1, 2 and 3 of
IEC 61851-1. The cables are of rated voltages U /U up to and including 450/750 V. Ordinary
duty cables with rated voltage 300/500 V are only permitted for charging mode 1 of
IEC 61851-1.
Maximum conductor operating temperature for the cables in this document is 90 ºC.
The test methods specified are given in IEC 62893-2, IEC 60245-2, IEC 60332-1-2,
IEC 62821-1:2015, Annex B and in the relevant parts of IEC 60811.
