Lithium-ion battery energy storage systems (Li-ion BESS)
have become critical to bridging the renewable energy supply-demand gap.
However, the exponential deployment of these systems has amplified fire-related
incidents, highlighting the need for robust fire protection design and
comprehensive certification programs.
In
this white paper, Jensen Hughes’ Joe Mayonado and Jihan El Ouaragli
team up with our fire protection experts to provide a comprehensive assessment
of UL 9540A, the primary testing standard for Li-ion BESS. They review the
current limitations of the UL 9540A certification program as well as the key
findings from their meta-analysis of publicly available datasets and UL 9540A
data.
By
maintaining progress in developing a dynamic, evidence-based approach to fire
safety in Li-ion BESS, we can help ensure the safe and scalable deployment of
next-generation global renewable energy infrastructure.
