Lithium battery energy storage safety incident

Did ESS deflagrate a lithium-ion battery energy storage system?

This report details a deflagration incident at a 2.16 MWh lithium-ion battery energy storage system (ESS) facility in Surprise, Ariz.

Are lithium ion batteries a fire hazard?

As is illustrated in the EPRI Energy Storage Integration Council (ESIC) Energy Storage Reference Fire Hazard Mitigation Analysis, lithium ion batteries are subject to several failure modes. Each mode may occur with diferent probabilities, based on the battery product and its integration.

What causes large-scale lithium-ion energy storage battery fires?

Conclusions Several large-scale lithium-ion energy storage battery fire incidents have involved explosions. The large explosion incidents, in which battery system enclosures are damaged, are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules.

Should lithium-ion storage batteries be protected?

Recently issued standards and regulations for lithium-ion storage battery systems now explicitly require protection to prevent and/or control thermal runaways leading to possible deflagrations. Other recently imposed measures are intended to limit electrical fault energies in battery control units.

What is a bibliography for lithium-ion battery energy storage systems?

The Bibliography provides references to applicable codes and standards, and other documents of interest. Read ACP's First Responders Guide to Lithium-Ion Battery Energy Storage System Incidents.

Is FSRI investigating near-miss lithium-ion battery energy storage system explosion?

FSRI releases new report investigating near-miss lithium-ion battery energy storage system explosion.
