Hierarchical selection of energy storage fire protection solutions: multi‑media combined protection has become the mainstream approach for large‑scale energy storage power stations.

As standalone energy storage and integrated solar-plus-storage projects are deployed at scale, the industry has reached a consensus: a single fire-suppression medium struggles to simultaneously meet multiple requirements, including early warning, module-level fire control, in-cabinet explosion suppression, and long-term prevention of reignition. Consequently, layered, zoned, multi-medium combined fire-protection solutions are becoming the preferred approach for large-scale energy storage projects.

Battery cluster, battery compartment, PCS Battery compartment, high-voltage distribution compartment, and local control cabinets each have entirely different risk characteristics depending on their protection zone: battery compartments prioritize cleanliness and insulation to suppress the spread of thermal runaway; electrical cabinets, BMS Enclosures are suitable for localized, precise detection and extinguishing; distribution rooms and cable tunnels must address cooling, fire control, and containment of spread.

Leveraging our comprehensive range of fire protection products, we can offer customized integrated solutions: for battery compartments, we recommend Perfluorohexanone, IG100、IG541 Clean Gas Systems; Batteries PACK , the interior of the distribution cabinet adopts fire detection tube, S Type aerosol Implement early-stage protection at the module level; coordinate with cable trenches and energy storage converter areas. High-pressure water mist, ultra-fine dry powder ; For unmanned, large-capacity sealed compartments, it can be equipped with Heptafluoropropane, high-pressure carbon dioxide Total flooding scheme. The entire system is integrated and interlocked. VOC , smoke and temperature composite detection, pressure relief, and damper interlocks, achieving “ Local suppression within the cabinet +  Total flooding fire suppression in the compartment +  Cooling to prevent reignition ”  End-to-end protection.

Different media each have their own advantages: inert gases excel at long-term inerting and explosion suppression; perfluorohexanone balances rapid fire extinguishing with low GWP Environmental protection indicators; high-pressure water mist excels at heat absorption and cooling, reducing the likelihood of lithium battery re-ignition; fire detection tubes and aerosol generators are suitable for small spaces, feature passive independent activation, and require no complex piping networks. During the design phase, consider project capacity, compartment type, whether the area is staffed, grid-connection acceptance criteria, and overseas requirements. UL/FM Certification requirements must align with the media to avoid risks of issues arising during later acceptance testing.

We have the capability to design, supply, and provide technical specifications across all product categories, and can integrate with energy storage systems. EPC The design institute has completed the scheme validation and coordinated documentation for physical fire testing, ensuring compatibility with domestic standards. GB/T51048、UL9540A、 NFPA855 Domestic and international fire safety codes for energy storage.
