UL stands for Underwriters Laboratories Inc., a prestigious and significant independent, non-profit organization dedicated to public safety in the United States and globally. It employs scientific testing methods to assess the safety and potential hazards of various materials, devices, products, equipment, and buildings. UL establishes, writes, and distributes relevant standards and information aimed at reducing and preventing losses to life and property, while also conducting field research. In summary, it specializes in product safety certification and safety assurance services, ultimately contributing to the availability of high-quality, safe products in the market and ensuring personal and property safety. As a means to eliminate technical barriers in international trade, UL plays a proactive role in promoting the development of global trade.

Lithium-ion battery UL certifications typically come in two types: UL 1642 and UL 2054; UL 1642 is for battery cells, while UL 2054 is for battery packs.

Scope of UL 2054 Standard:

For secondary (rechargeable) batteries, which include single-cell, two or more multi-cell series/parallel configurations of battery packs.

UL2054 Standard Test Items:

The testing items for UL2054 primarily include electrical tests (short-circuit test, overcharge test, abuse overcharge test, over-discharge test, power source limitation test), mechanical tests (compression test, impact test, acceleration test, vibration test), battery pack housing test, drop impact test, 250N static force test, mold pressure release test, fire bake test, projection test, environmental test, high-temperature test, and temperature cycling test, among others.
