UL 2580 Standard Battery Testing

There is a responsibility to guarantee the safety of battery systems in electrified vehicles, not only for daily operation but also in the face of unforeseen events or challenging environments. Fire hazards, thermal runaway and other risks associated with energy storage systems must be thoroughly understood and mitigated to ensure public safety and prevent costly incidents.

The UL 2580 standard, developed by Underwriters Laboratories (UL), outlines a comprehensive set of safety requirements and test methods to assess the safety and response of electrical energy storage assemblies. The UL 2580 Testing Standard for Batteries for Use in Electric Vehicles ensures these assemblies meet stringent safety criteria, minimizing risks associated with electrical, thermal, environmental and mechanical hazards.

UL 2580 Battery Test Methods

Southwest Research Institute (SwRI) is equipped with state-of-the-art equipment and staffed by experts in energy storage safety to perform all the below UL 2580 tests as well as customized developmental testing. The UL 2580 standard was established to evaluate the safety of lithium-ion batteries for use in electric vehicles (EVs). The comprehensive suite of tests encompasses various aspects such as electrical, mechanical, thermal and environmental evaluations. SwRI can perform all the below tests from UL 2580 and can assist clients with developmental testing if modifications to the test standard are desired.
