Battery Energy Storage System Hazard Assessment: Modeling and Scaling Up
Dong Zeng
Principal Research Scientist, FM Global
ABSTRACT:
The increased utilization of lithium-ion batteries (LIB) in battery energy storage systems (BESS) for utility-scale renewable energy generation has drawn attention to better understanding the associated fire and explosion hazards. These hazards are attributable to the heat and flammable gases released during LIB thermal runaway (TR). The energy released from cells that undergo TR causes inter-cell thermal runaway propagation (TRP). Fire and sensible heat generation from the TRP of a module can trigger inter-module TRP and, ultimately, large-scale fire or explosion. Hazard assessments are critical to preventing and protecting such incidents, and numerical modeling is a key tool in developing such assessments. For this purpose, FM has conducted a systematic experimental study spanning LIB cells, modules, and multi-module LIB units using NMC/graphite pouch-type cells with a capacity of 63 Ah. A novel cell thermal runaway modeling approach based on single-cell TR experiments was developed and applied to predict module-level fire hazards, with the final objective of predicting unit-level fire and explosion hazards. This presentation will discuss the problem background, experimental findings, and the progress of modeling.
SPEAKER:
Dr. Dong Zeng is a principal research scientist and technical team leader for the flammability team at FM’s Research division. He obtained a PhD in Chemical Engineering from Brigham Young University. At FM, he is responsible for leading a broad range of research programs to improve fire hazard evaluation and mitigation, with current focus on lithium-ion batteries, roof-mounted solar panels, data centers, and building materials. His work has led to multiple FM Approvals standards, computational fluid dynamics (CFD) validation datasets (MaCFP), and more than thirty peer-reviewed publications. He is a principal member of the NFPA (National Fire Protection Association) Fire Tests Committee and is responsible for developing and maintaining multiple fire testing standards. He served as a colloquium co-chair for the International Symposium of Combustion, the International Association for Fire Safety Science, and the organizer for the SFPE Li-ion Battery Fire Safety Conference.
