Introduction
Lithium-ion battery systems are efficient rechargeable energy storage systems for electrically propelled
road vehicles. The requirements for lithium-ion battery systems to be used as power source for the
propulsion of electric road vehicles are significantly different to those batteries used for consumer
electronics or for stationary applications.
Lithium-ion batteries can store electricity at relatively high-energy density compared to other battery
chemistries currently available. Under current state of art, most lithium-ion batteries use organic
electrolytes classified as Class 3 “flammable liquid” under “UN Recommendations on the Transport of
Dangerous Goods – Model Regulations”. Therefore, mitigating potential hazards associated with fire or
explosion of lithium-ion batteries are considered as an important issue.
The EN 50604-1 series is read in conjunction with ISO 12405-3:2014 (withdrawn) and ISO 6469-1:2019
(for this amendment). The clauses of the particular requirements in EN 50604-1 supplement or modify
the corresponding clauses in ISO 12405-3:2014 (withdrawn) and ISO 6469-1:2019 (for this
amendment). Where the text indicates an “addition” to or a “replacement” of the relevant requirement,
test specification or explanation of ISO 12405-3:2014 (withdrawn) and ISO 6469-1:2019 (for this
amendment), these changes are made to the relevant text of ISO 12405-3:2014 (withdrawn) and
ISO 6469-1:2019 (for this amendment), which then becomes part of the standard. Where no change is
necessary, the words “This clause of ISO 12405-3:2014 is applicable” are used.
Test items were selected to simulate conditions likely to occur during handling (e.g. removal or
replacement) or during operation. They cover conditions of normal operation, rough handling and as
well likely conditions of misuse or negligent handling. For electric vehicles operating under extreme
conditions (e.g. off-road, extreme climate etc.) additional requirements could be necessary which are
not covered by this document.
NOTE Additional requirements might also apply to battery system after the integration into the vehicle resulting
from national or regional regulations and are not dealt with in this document. Same applies to hazards from electric
shock.
This document provides specific test procedures and related requirements to ensure an appropriate and
acceptable level of safety of lithium-ion (Li-ion) battery systems specifically developed for propulsion of
road vehicles. Propositions for other chemistries are given in informative Annex HH.
This document indicates references to the UN Recommendations on the Transport of Dangerous
Goods – Manual of Tests and Criteria: Section 38.3 which are performed independently from this testing
program. Test reports issued by an ILAC, APLAC or similar accredited party are acceptable for the
battery system complying with all aspects of Section 38.3 of Manual of Tests and Criteria of UN
Recommendations on the Transport of Dangerous Goods for this test option. Test reports issued and
verified by in house testing according to UN 38.3 are also accepted.
1 Modification to Clause 1, “Scope”
Replace the 3rd paragraph by the following:
“Light EV includes all electrically propelled vehicles of category L1 up to category L7 according to the
definition of ECE-TRANS-WP29-78r6e and all electrically propelled or assisted cycles including plug-in
hybrid road vehicles (PHEV), that derive all or part of their energy from on-board rechargeable energy
storage systems (RESS).“
Delete the 5th paragraph.
Add after NOTE and renumber it NOTE 1:
“This document also applies to:
— built-in battery packs/systems in EVs.
NOTE 2 Informative Annex HH gives information on possible tests for other chemistries.“
Replace the first and second point of the last paragraph by:
“
— individual cells;
— non-removable battery systems;“
2 Modification to Clause 2, “Normative references”
Add the following new references:
