EN 50604-1:2016 (E) European foreword This document (EN 50604-1:2016) has been prepared by CLC/TC 21X “Secondary cells and batteries”. The following dates are fixed: • latest date by which the existence of this document has to be announced at national level (doa) 2017–01–04 • latest date by which this document has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2017–07–04 • latest date by which the national standards conflicting with this document have to be withdrawn (dow) 2019–07–04 The goal of this standard is to increase safety of battery packs/ systems which contain lithium battery technologies in combination with their voltage converter unit for use in light electric vehicles. Part 1 sets definitions, safety issues and test procedures. This standard was designed to assess aspects on battery pack/system level. This standard covers the Principal Elements of the Safety Objectives for Electrical Equipment Designed for Use within Certain Voltage Limits (LVD - 2006/95/EC). This standard covers the Principal Elements of the Safety Objectives for battery packs/systems Designed for Use by Light EVs (Directive 2002/24/EC, Regulation (EU) 168/2013). Light EV includes all electrically propelled two, three and four wheeled vehicles of category L1 up to Category L7 according to the definition of ECE/TR ANS-WP29-78r2e 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). This standard covers issues mentioned in EU Mandate M/468 and M/533. This part is to be used in conjunction with the appropriate part of the ISO 12405- series. NOTE The following print types are used: – requirements: in roman type; – test specifications: in italic type; – notes: in small roman type. 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. SIST EN 50604-1:2016

EN 50604-1:2016 (E) 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 may 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 which are 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 is considered an important issue. EN 50604-1 will be read in conjunction with ISO 12405-3. The clauses of the particular requirements in EN 50604-1 supplement or modify the corresponding clauses in ISO 12405-3. Where the text indicates an “addition” to or a “replacement” of the relevant requirement, test specification or explanation of ISO 12405-3, these changes are made to the relevant text of ISO 12405-3, which then becomes part of the standard. Where no change is necessary, the words “This (sub)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 may be necessary which are not covered by this standard. Additional requirements might also apply to battery system after the integration into the vehicle resulting from national or regional regulations and are not dealt within this standard. Same applies to hazards from electric shock. This European Standard provides specific test procedures and related requirements to ensure an appropriate and acceptable level of safety of lithium-ion battery systems specifically developed for propulsion of road vehicles. This standard refers 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. SIST EN 50604-1:2016

EN 50604-1:2016 (E) 1 Scope This European Standard specifies test procedures and provides acceptable safety requirements for voltage class A and voltage class B removable lithium-ion battery (packs and) systems, to be used as traction batteries of or for electrically propelled road vehicles. This European Standard is related to the testing of safety performance of battery packs and systems for their intended use for a vehicle. This European Standard is not intended to be applied for the evaluation of the safety of battery packs/systems storage, vehicle production, repair and maintenance services. Light EV includes all electrically propelled two, three and four wheeled vehicles of category L1 up to Category L7 according to the definition of ECE/TR ANS-WP29-78r2e 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). This European Standard enables setting up a dedicated test plan for an individual battery pack/system subject to an agreement between customer and supplier. If required, the relevant test procedures and/or test conditions of lithium-ion battery packs and systems may be selected from the standard tests provided in this standard to configure a dedicated test plan. This European Standard applies to all battery systems intended to be used in conjunction with products or systems described in the IEC/TS 61851-3 series. NOTE

Testing on cell level is specified in the IEC 62660 series. This European Standard does not apply to: – lithium cells; – batteries other than lithium ion types; – primary Batteries(including lithium types); – batteries covered by the ISO 12405- series. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
