Lithium-ion Traction battery pack and system for electric vehicles--Part 3: Safety requirements and test methods
(ISO 12405-3:2014,Electrically propelled road vehicles-Test specification for Lithium-ion traction battery packs and systems-Part 3:Safety performance requirements,NEQ)
This standard mainly stipulates the safety requirements and test methods for lithium-ion power battery packs and systems for electric vehicles. It is mainly applicable to lithium-ion power battery packs and systems installed in electric vehicles. At the same time, nickel-metal hydride power battery packs and systems can also refer to it.
Battery pack safety testing mainly includes the following items:
