Outdoor fire protection design for energy storage battery compartment

Can a lithium-ion battery energy storage system detect a fire?

Since December 2019, Siemens has been offering a VdS-certified fire detection concept for stationary lithium-ion battery energy storage systems.* Through Siemens research with multiple lithium-ion battery manufacturers, the FDA unit has proven to detect a pending battery fire event up to 5 times faster than competitive detection technologies.

What is battery energy storage fire prevention & mitigation?

In 2019, EPRI began the Battery Energy Storage Fire Prevention and Mitigation – Phase I research project, convened a group of experts, and conducted a series of energy storage site surveys and industry workshops to identify critical research and development (R&D) needs regarding battery safety.

Are lithium-ion batteries safe in outdoor enclosures?

As demand for electrical energy storage systems (ESS) has expanded, safety has become a critical concern. This article examines lithium-ion battery ESS housed in outdoor enclosures, which represent the most common configuration for these systems.

Are battery energy storage systems safe?

Owners of energy storage need to be sure that they can deploy systems safely. Over a recent 18-month period ending in early 2020, over two dozen large-scale battery energy storage sites around the world had experienced failures that resulted in destructive fires. In total, more than 180 MWh were involved in the fires.

Why is a battery storage system important?

The combination of high energy densities and flammable electrolytes puts high demands on associated fire protection systems. ◼ Statistics1 show that electrical fires account for over 25% of major fire losses in industrial companies. ◼ The importance of Li-ion battery storage systems has increased dramatically in recent years.

How do you protect a battery module from a fire?

The most practical protection option is usually an external, fixed firefighting system. A fixed firefighting system does not stop an already occurring thermal runaway sequence within a battery module, but it can prevent fire spread from module to module, or from pack to pack, or to adjacent combustibles within the space.
