Electric vehicle battery swap system - Part 2: Safety requirements

IEC 62840-2:2016 provides the safety requirements for a battery swap system, for the purposes of swapping swappable battery system (SBS) of electric vehicles. The battery swap system is intended to be connected to the supply network. The power supply is up to 1 000 V AC or up to 1 500 V d.c, in accordance with IEC 60038. This standard also applies to battery swap systems supplied from on-site storage systems (e.g. buffer batteries). This publication is to be read in conjunction with IEC 62840-1:2016.

Système d'échange de batterie de véhicule électrique - Partie 2: Exigences de sécurité

L'IEC 62840-2:2016 spécifie les exigences de sécurité relatives à un système d'échange de batterie, pour remplacer le système de batterie échangeable (SBS) des véhicules électriques. Le système d'échange de batterie est destiné à être connecté au réseau électrique. L'alimentation atteint 1 000 V en courant alternatif ou 1 500 V en courant continu, conformément à l'IEC 60038. La présente norme s'applique également aux systèmes d'échange de batterie alimentés par des systèmes de stockage sur site (par exemple, des batteries tampons). Cette publication doit être lue conjointement avec la IEC 62840-1:2016

Sistem menjave baterij električnih vozil - 2. del: Varnostne zahteve

Ta del standarda IEC 62840 podaja varnostne zahteve za sistem menjave baterij za namene menjave zamenljivih baterijskih sistemov (SBS) pri električnih vozilih. Sistem menjave baterij je predviden za priključitev na napajalno omrežje. Zmogljivost električnega napajalnika je največ 1000 V pri izmeničnem toku ali največ 1500 V pri enosmernem toku v skladu s standardom IEC 60038.
Ta standard se uporablja tudi za sisteme menjave baterij, dobavljene iz sistemov za shranjevanje na mestu uporabe (npr. nadomestne baterije).
Vidiki, zajeti v tem standardu:
• varnostne zahteve sistema menjave baterij in/ali njegovih sistemov;
• varnostne zahteve za komunikacijo;
• elektromagnetna združljivost (EMC);
• oznake in navodila;
• zaščita pred električnim udarom in drugimi nevarnostmi.
Ta standard se uporablja za sisteme menjave baterij za električna vozila, opremljena z vsaj enim sistemom SBS.
OPOMBA: Obravnavani so sistemi menjave baterij za lahka električna vozila v skladu s skupino standardov IEC 61851-3.
Ta standard se ne uporablja za:
• vidike v povezavi z vzdrževanjem in servisiranjem postaje za menjavo baterij (BSS);
• trolejbuse, železniška vozila in vozila, ki so namenjena predvsem za uporabo zunaj cestišč;
• vzdrževanje in servisiranje električnih vozil.

ELECTRIC VEHICLE BATTERY SWAP SYSTEM –
Part 2: Safety requirements
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 62840-2 has been prepared by IEC technical committee 69:

Electric road vehicles and electric industrial trucks.
The text of this standard is based on the following documents:

States).
– 10.4: three-part cautionary statements are required (United States).

The committee has decided that the contents of this publication will remain unchanged until

INTRODUCTION

The purpose of the battery swap system is to provide energy partly or in total to electric

vehicles (EV) through fast replacement of their swappable battery systems (SBS). While

charging, the EV typically takes a relatively long time, whereas the battery swap process

takes only a few minutes to complete. Thus it will reduce the range anxiety and will facilitate

travel for longer distances.

As there is a possibility to charge the batteries after their removal from the vehicle in various

ways, the impact of this process on the critical infrastructure of the electrical grid can be

minimized.
Battery swap stations mainly include one or more of the following functions:
• swap of EV swappable battery system (SBS);
• storage of EV SBS;
• charging and cooling of EV SBS;
• testing, maintenance and safety management of EV SBS.

This part of IEC 62840 serves as a generic approach for safety during the lifecycle of battery

swap systems and stations for electric vehicles.

ELECTRIC VEHICLE BATTERY SWAP SYSTEM –
Part 2: Safety requirements
1 Scope

This part of IEC 62840 provides the safety requirements for a battery swap system, for the

purposes of swapping swappable battery system (SBS) of electric vehicles. The battery swap

system is intended to be connected to the supply network. The power supply is up to 1 000 V

AC or up to 1 500 V d.c, in accordance with IEC 60038.

This standard also applies to battery swap systems supplied from on-site storage systems

(e.g. buffer batteries).
Aspects covered in this standard:
• safety requirements of the battery swap system and/or its systems;
• security requirements for communication;
• electromagnetic compatibility (EMC);
• signs and instructions;
• protection against electric shock and other hazards.

This standard is applicable to battery swap systems for EV equipped with one or more SBS.
