What is BS EN 50604‑1 about?

BS EN 50604‑1 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.

BS EN 50604‑1 is related to the testing of the safety performance of battery packs and systems for their intended use for a vehicle.

Note 1: BS EN 50604‑1 also applies to built-in battery packs/systems in EVs.

Note 2: BS EN 50604‑1 does not apply to individual cells, non-removable battery systems, primary batteries (including lithium types), batteries covered by the ISO 12405- series.

Note 3: BS EN 50604‑1 is not intended to be applied for the evaluation of the safety of the battery packs/systems storage, vehicle production, repair, and maintenance services.

Who is BS EN 50604‑1 for?

BS EN 50604‑1 on safety requirements and test methods for secondary lithium batteries is for:

Secondary lithium batteries manufacturers
Suppliers and dealers of secondary lithium batteries
Service providers and installers of secondary lithium batteries
Test conductors for secondary lithium batteries

Why should you use BS EN 50604‑1?

Lithium-ion battery systems are efficient rechargeable energy storage systems for electrically propelled road vehicles.

BS EN 50604‑1 explains to you how the requirements for lithium-ion battery systems that are used as a power source for the propulsion of electric road vehicles are significantly different from the batteries used for consumer electronics or for stationary applications.

BS EN 50604‑1 specifies the advantages of using lithium-ion batteries like, they may store electricity at a relatively high energy density compared to other battery chemistries currently available.

BS EN 50604‑1 provides you with specific test procedures and related requirements to ensure an appropriate and acceptable level of safety of lithium-ion battery systems specifically developed for the propulsion of road vehicles. Mitigating potential hazards associated with fire or explosion of lithium-ion batteries is considered an important issue.
