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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 62840-2 has been prepared by IEC technical committee 69: Electrical power/energy
transfer systems for electrically propelled road vehicles and industrial trucks. It is an
International Standard.
This second edition cancels and replaces the first edition published in 2016. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) expands the scope to encompass both swappable battery systems (SBS) and handheld
swappable battery systems (HBS);
b) introduces stricter interoperability requirements through detailed system interface
specifications and defined state transition protocols;
c) enhances data security by defining safety message transmission protocols and integrating
telecom network requirements;
IEC 62840-2:2025 © IEC 2025
d) increases electrical safety protection levels for battery swap stations (BSS) with specified
capacitor discharge time limits to mitigate electric shock risks;
e) introduces enhanced mechanical safety requirements for automated battery handling
systems, with technical alignment to ISO 10218-1 and ISO 10218-2;
f) strengthens overload and short-circuit protection for BSS through standardized testing
methods and overcurrent protection specifications;
g) defines upgraded electromagnetic compatibility (EMC) standards to ensure system
resilience against external interference, supplemented with EMC-related functional safety
measures.
The text of this International Standard is based on the following documents:

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) or handheld-
swappable battery systems (HBS). The battery swap system aims to provide energy to electric
road vehicles by quickly replacing their swappable battery system or handheld-swappable
battery system. This may help alleviate range anxiety and make longer distance travel more
convenient.
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 is minimized.
Battery swap stations mainly include one or more of the following functions:
• swap of EV SBS or HBS;
• storage of EV SBS or HBS;
• charging and cooling of EV SBS or HBS;
• testing, maintenance and safety management of EV SBS or HBS.
This document serves as a generic approach for safety during the lifecycle of battery swap
systems and stations for electric vehicles.
This document contains the general safety requirements for battery swap system of SBS/HBS.
The specific safety requirements for dedicated system are described in other parts of the
IEC 62840 series.
IEC 62840-2:2025 © IEC 2025
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)/handheld-swappable battery system
(HBS) 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 DC in accordance with
IEC 60038.
This document also applies to battery swap systems supplied from on-site storage systems (e.g.
buffer batteries).
Aspects covered in this document:
• safety requirements of the battery swap system and its subsystems;
• security requirements for communication;
• electromagnetic compatibility (EMC);
• marking and instructions;
• protection against electric shock and other hazards.
This document is applicable to battery swap systems for EV equipped with one or more
