Overview

EN 50620:2017/A1:2019 is an amendment to the European standard EN 50620:2017 that clarifies scope, corrects wording, and adds regulatory relationship information (Annex ZZ). It defines requirements and tests for the pure cable component of charging cables used between the electricity supply point or charging station and the electric vehicle (EV) or plug‑in hybrid (PHEV). The amendment was prepared under CENELEC mandate M/511 and explicitly links the standard to the Low Voltage Directive (2014/35/EU).

Key topics and requirements

• Scope clarification: The standard covers only the cable component - accessories and plugs are excluded. Cables may be:
  • integral to the vehicle (case A EN 61851‑1),
  • the detachable cable part of a cable assembly (case B), or
  • permanently attached to a fixed charging point (case C).
• Charging modes: Applicable to charging modes 1–3 of EN 61851‑1 and intended to supply power and communication to EVs and PHEVs.
• Core size correction: Sizes for CC/CP cores are corrected in the amendment to cover the range 0.5 mm to 1.0 mm (as stated in the amendment).
• Test updates: Table 5 was updated to add a long‑term DC resistance test for power cores (sample length 5 m, duration 240 h, water temperature 80 ± 5 °C) with the performance requirement of no breakdown.
• Sampling guidance: No fixed sampling rate is imposed; “adequate” sampling is to be agreed between manufacturer and purchaser and based on the manufacturer’s quality scheme and lot size.
• Regulatory linkage (Annex ZZ): Annex ZZ maps EN 50620 clauses to the safety objectives of the Low Voltage Directive (2014/35/EU), clarifying presumption of conformity when the standard is cited in the Official Journal.

Applications and users

Who should use EN 50620:2017/A1:2019:

• Cable manufacturers designing and testing EV charging cables
• EV and charging‑station OEMs specifying compliant cable components
• Test laboratories performing type and routine tests for conformity
• Procurement teams and purchasers defining contract sampling and quality requirements
• Regulators and notified bodies assessing conformity with the Low Voltage Directive

Practical uses:

• Specifying cable construction, electrical and mechanical tests for EV charging applications
• Incorporating into procurement and quality agreements (sampling and test regimes)
• Demonstrating presumption of conformity with LVD requirements where applicable

Related standards

• EN 50620 (base standard)
• EN 61851‑1 (EV charging system application/charging modes)
• EN 50565‑1 (guide for use and selection)
• EN 50395 (referenced for long‑term DC resistance test)
• HD 60364 (installation rules) - system‑level safety and installation requirements

European foreword
This document (EN 50620:2017/A1:2019) has been prepared by CLC/TC 20 “Electric cables”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2020-03-20
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2022-03-20
conflicting with this document have to be
withdrawn
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association.
For the relationship with EU Directive(s) see informative Annex ZZ, which is an integral part of this
document.
Introduction
This amendment to EN 50620:2017 is needed to clarify and correct the wording of EN 50620 and to
amend Annex ZZ, giving the relationship of the requirements of the Low Voltage Directive (2014/35/EU)
to the content of EN 50620.
a) The Scope has to be clearly defined, giving precise limits of the product. Under item b) of the Scope
it is stated that cord sets are included. The wording has been modified to show that all kinds of
accessories and plugs are excluded from the scope of this standard.
b) The Introduction is not present in EN 50620, it is not clear why the standard is needed. The
amendment covers the history from the Vilamoura notification from Germany and response from
CLC TC20 to cover the project on European level, based on the need for a specific cable for power
supply to electric vehicles.
c) The identification of the Legislation and Standardization Request has to be clear and unambiguous.
The “European foreword” of EN 50620:2016 has been amended to mention the LVD and mandate
M/511.
d) The sizes of the CC/CP cores in 6.2 have to be corrected to cover the range from 0,5 mm to
1,0 mm .
e) All relevant (significant) essential or other legal requirements have been identified (under
consideration of possible limitations in the scope), e.g. significant hazards. See Annex ZZ.
f) Where appropriate, for the identified relevant (significant) requirements, appropriate and verifiable
measures for reduction of uncertainty or risk have been specified (as far as possible performance
based). See Annex ZZ.
g) The requirements have to be compatible with good safety engineering practice, state of the art
safety expertise or appropriate reference standards. A remark about sampling requirements for the
sample test have been added, explaining that no rule on frequency is possible for this special
product, therefore this item will be subject to the contract parties / as requested by the customer.
Sample Tests should be carried out on samples taken according to quality control procedures
agreed between manufacturer and purchaser.
Measurement uncertainties/tolerances are given in the test method standards. Yes/no covering the
pass/fail criterion need no uncertainty, limit values do not need uncertainty ranges.
h) The terms and definitions correspond to the terms and definitions appropriate to cable standards in
IEC and CLC. “Type test” definition from electropedia is based on a different product, therefore no
modification will be introduced. Any deviation in these generic definitions are not able to be in
conflict to the essential requirements in the LVD.
1 Modification to the European foreword
Replace the last paragraph of the European foreword, starting with “This document has been
prepared .”. by the following new paragraphs:
This document has been prepared under a mandate (M/511) given to CENELEC by the European
Commission and the European Free Trade Association, and supports EU Regulation.
For the relationship with EU Regulation (2014/35/EU) see informative Annex ZZ, which is an integral
part of this document.
Additional relevant Directives and Regulations may be applicable and impose supplementary
requirements.
2 Modification to the Introduction
Add the following Introduction:
Introduction

of TC20 to carry out the work this document has been prepared to cover the subject by a European
document.

plug-in hybrid vehicle.
