The battery pack standards mainly include multiple standards and specifications such as the International Electrotechnical Commission (IEC), Underwriters Laboratories (UL), Japanese Industrial Standards (JIS), and Chinese National Standards (GB). These standards cover multiple aspects of battery pack safety, performance, transportation, etc., ensuring the safety and consistency of battery packs during use and transportation.
International Electrotechnical Commission (IEC) standards
The IEC standard is one of the most widely adopted battery standards worldwide, mainly including the following standards:
IEC 62133: Safety standard for rechargeable lithium batteries used in portable electronic devices, covering battery design, structure, and testing requirements.
IEC 61960: specifies performance testing, labeling, sizing, and other requirements for lithium-ion secondary batteries and battery packs in portable applications.
IEC 62619: Safety requirements for large lithium-ion batteries and battery packs for industrial applications.
IEC 62281: Standard for the safety of transportation of lithium batteries and battery packs.
Underwriters Laboratories (UL) standards in the United States
UL standards are widely used in the North American market and gradually recognized globally, mainly including the following standards:
UL 1642: Safety testing for lithium batteries, covering safety testing for individual batteries.
UL 2054: Safety standard for rechargeable battery packs, including various chemical systems such as lithium-ion and nickel hydrogen.
UL 2271: A safety standard specifically designed for battery packs used in electric vehicles.
UL 9540A: Thermal runaway assessment testing method for energy storage systems.
Japanese Industrial Standards (JIS)
JIS standards are widely adopted in Japan, mainly including the following standards:
JIS C 8714: specifies the safety requirements for portable lithium-ion secondary batteries.
JIS C 8715: Performance testing methods for portable lithium-ion secondary batteries.
Chinese National Standard (GB)
The GB standard is widely adopted in China, mainly including the following standards:
GB/T 18287: Safety requirements for lithium-ion batteries and battery packs for portable power sources.
GB 31241: Safety requirements for lithium-ion batteries and battery packs for portable electronic products.
GB/T 31484: Cycle life requirements and test methods for power batteries used in electric vehicles.
