CLC/TC 21X/WG 05 - Li Batteries: General Requirements Group EN 50343

This amendment of EN 50604-1 provides clarification to questions raised by test institutes for being able to proceed in testing according to the standard. It is ready for immediate release / publication.

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.

This European standard specifies test procedures for performance and durability aspects of light means of transport (LMT) batteries. These are sealed batteries with a maximum weight of 25 kg that are specifically designed to provide electric power for the traction of wheeled vehicles that can be propelled by an electric motor alone or by a combination of motor and human power, including type-approved vehicles of category L within the meaning of Regulation (EU) No 168/2013 of the European Parliament and of the Council, and that is not an electric vehicle battery. The scope of this document is restricted to lithium-ion batteries. LMT batteries contain at least the following general classes: • Batteries of L-category vehicles referred to in Article 2 of Regulation EU 168/2013 of the European Parliament and of the Council (e.g., batteries for light motorcycles, trikes and quads), where the battery weight is less than 25 kg. • Batteries for EPACs (electronically power assisted cycle) with or without type approval • Batteries for micro mobility devices like e.g., e-kick-scooters, hoverboards, self-balancing vehicles… Batteries above 25 kg for mobility are not in the scope of this standard, even though they may be used in L category vehicles (e.g. L7 category). Batteries for toys are also not in the scope of this standard based on the recital 15 of (EU) 2023/1542: "Batteries used for traction in wheeled vehicles considered to be toys within the meaning of Directive 2009/48/EC of the European Parliament and of the Council, should, for the purposes of this Regulation, not be considered to be LMT batteries, but to be portable batteries." For reused, remanufactured, repaired and repurposed (here further called “R”) batteries the same procedures have to be applied. The tests listed here have to be conducted and documented. If this is not possible, equivalent tests have to be performed. However, this document does not aim to specify detailed test procedures specifically for these kinds of “R”-batteries.
