European foreword
This document (EN 18061:2025) has been prepared by Technical Committee CEN/TC 301 “Road
vehicles”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by February 2026, and conflicting national standards shall
be withdrawn at the latest by February 2026.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,

Introduction
European Commission published the standardization request M/579 to the European standardization
organisations as regards to performance and sustainability requirements for batteries.
Battery systems are an efficient energy storage system for electrically propelled vehicles. The steps,
conditions and protocols for the safe repair and re-use and preparation for repurposing of modules and
batteries designed for EV applications are significantly different from those batteries used for consumer
electronics or stationary usage.
There are potential safety risks to be considered before reusing an EV battery system, battery pack and
battery modules. These should be thoroughly addressed before considering any kind of re-use
operations. Further, all re-used batteries or sub-units of batteries shall comply with all safety, transport
and product testing at the same level as new battery products (except tests requiring destructive
sampling).
This document provides specific steps, conditions and protocols for the safe repair and re-use and
preparation for repurposing of modules and batteries designed for EV battery systems, battery packs and
battery modules.
This document includes technical provisions to facilitate the safe repair and re-use and preparation for
repurposing of EV battery systems, battery packs and battery modules.
This document also includes an informative annex on guidance on design and assembly techniques
facilitating the maintenance, repair, re-use and preparation for repurposing of batteries designed for EV
applications.
NOTE This document is not intended for any repurposing of EV batteries, only for preparation for repurposing.

1 Scope
This document describes steps, conditions and protocols for safe maintenance and repair to facilitate
remanufacturing, re-use and preparation for repurposing of battery systems, battery packs and battery
modules designed for EV applications for alkali-ion (Li-ion, Na-ion), Pb, NiMH and combined chemistries.
This document also includes an informative guidance on design and assembly techniques that facilitate
the maintenance, repair, re-use and preparation for repurposing of EV battery systems, battery packs and
battery modules (Annex B).
NOTE Individual cell is replaced when it is allowed and described by the EV battery systems, battery packs and
battery modules manufacturer. In this case, battery modules manufacturer provides the necessary instructions for
cell replacement.
