Fike’s Layers of Protection for BESS Safety

Thermal management is the only solution proven to stop the propagation of thermal runaway. Fike Blue is a thermal management system that is third-party tested and proven to stop propagating thermal runaway by immersing the affected battery module, absorbing the heat without breaking down and cooling the battery cells before adjacent cells are also compromised.

Batteries that fail during thermal runaway produce dangerous and explosive mixtures of offgas. That's why an expert like Fike is needed to meet NFPA 855 standards on "explosion control," which may include explosion vent panels, exhaust ventilation and even Fike Blue to minimize the amount of potential offgas. Furthermore, explosion control often includes gas detection…

Li-ion battery gas detection systems are often a necessary component to the overall protection strategy of a BESS. However, their installation can often be a time-consuming process. Fike’s Custom Li-ion Gas Detection Kit leverages nearly any existing system such as Li-ion Tamer and pre-assembles it to fit any BESS, saving hours of installation time per unit.

To meet the unique safety demands of nearly any BESS or a renewable energy production process, additional detection methods may be chosen instead of or in-tandem with early warning gas detection systems. These may include Fike Distributed Temperature Sensing Cables, standard heat, smoke and gas detectors, thermal imaging cameras and Fike Flame Detectors.

Fires outside of BESS

Fires may originate from adjacent control rooms with high voltage switch gears, HVAC and other electronics. These fires may reach battery modules and begin the thermal runaway process. While ineffective for suppressing thermal runaway, Fike's fire suppression solutions such as SF 1230 and FK-5-1-12 are effective for these types of electrical fires.

Because every BESS is unique, a dedicated team of experts are needed to assess the potential hazards, design the system required to mitigate a thermal runaway event, and provide testing and validation to meet UL 9540A standards. Fike is the only industrial safety solutions provider in the world with the ability to offer these layers of protection.

Why Does a BESS Require a Protection Strategy?

Thermal runaway within li-ion batteries and BESS occur more often than one might think, as many of these incidents go unreported. Just one malfunctioning battery creates a chain reaction into adjacent batteries and produces flammable gases and fire in the enclosed space. Incidents such as these are now commonplace, which is why regulations and legislation are quickly evolving. Here’s how cascading thermal runaway occurs:

lithium ion battery malfunction

Battery Malfunctions

The battery’s internal temperature quickly exceeds its normal operating range and begins to self-heat.

lithium battery off-gassing from thermal runaway

Offgas Releases

Explosive gases such as hydrogen are released as a byproduct of thermal runaway.

thermal runaway in battery energy storage systems

Hazard Spreads

Nearby batteries begin to malfunction as well from the intense heat, creating a chain reaction.

thermal runaway consumes entire rack

BESS Consumed

No solution has been proven to stop this thermal event, until the discovery of Fike Blue.

Fike Blue - Propagating Thermal Runaway Suppression

Fike Blue is the first third-party tested thermal management solution proven to not only suppress battery fires but also a cascading thermal runaway event. Learn how Fike Blue works to control these extremely dangerous hazards and makes the deployment of a BESS into nearly any environment possible.
