Recently, the LSFT large-scale battery cabin fire test platform has shone brilliantly in rigorous real-world scenarios. The open-door limit combustion test of the Haichen Energy Storage ∞ Block 5MWh energy storage system, built and assisted by Jiangsu Firemana, was successfully conducted under the witness of international authoritative institutions such as UL, American Certified Fire Protection Engineers, and customers. The test strictly adhered to UL9540A and NFPA855 standards and achieved complete success. The test unprecedentedly challenged four major combustion limit conditions:

The world's first "open-door combustion" test: The cabinet door was kept open throughout the entire test process, creating an "unconstrained combustion" environment (with sufficient and free-flowing oxygen), to verify the safety protection capability of the system structure under extreme and harsh conditions at high temperatures.

Industry-limiting "Double 15cm Spacing": The cabinet spacing is compressed to the industry-limiting 15cm, simulating a dense deployment of "back-to-back, side-by-side". Facing the high temperature of flames above 1300℃, the adjacent cabinets successfully achieved "zero heat spread", verifying the system's ability to isolate thermal runaway under extreme close proximity.

"Active fire protection system is turned off": The external fire intervention is completely shut down, relying solely on the system's own passive fire protection design to withstand prolonged intense fire tests. This successfully verifies the system's autonomous fire protection capability and high reliability without external support.

"100% SOC (State of Charge) fully charged state": Conduct testing under fully charged conditions to maximize the scale of thermal runaway energy release, verifying the reliability and stability of the system under the most severe energy conditions.

After undergoing an extremely thorough combustion process lasting for 15 hours, the experiment yielded breakthrough results:

The 5MWh system from Haichen Energy Storage triggered the prefabricated cabin structure to maintain its integrity.

None of the three adjacent boxes exhibited any thermal runaway phenomenon.

Successfully overcome the multiple extreme tests of "opening the door + extreme spacing + long-term combustion + full charge + no external assistance".

It is a great honor that the test site and analysis equipment for this experiment were all set up by Jiangsu Firemana. The independently developed LSFT large-scale fire test platform, with its reasonable site layout planning, high-performance monitoring and analysis instruments, and professional testing technicians, assisted Haichen Energy Storage in successfully completing this test.

The LSFT large-scale fire testing platform, developed by Jiangsu Firemana, is designed to meet the market demand for fire safety testing of energy storage batteries. By simulating fire scenarios in energy storage systems under real-world conditions, it evaluates core concerns such as fire spread paths, chain reaction prevention and control, and the effectiveness of fire protection systems. It verifies the disaster resilience of system engineering and addresses the shortcomings of traditional testing methods, which focus on single-point thermal runaway of batteries and lack predictability in the complexity and cascading risks of real-world conditions in large-scale energy storage systems.

This experiment fully demonstrates the immense value of Firemana's "Large-scale Fire Testing Platform for Energy Storage Battery Cabinets":

It successfully replicates and bears extraordinary extreme testing scenarios.

Its powerful data acquisition capability provides an irrefutable scientific basis for verifying system performance.

It provides invaluable practical experience and authoritative reference examples for the industry in the formulation of safety standards (such as stricter fire separation distances, passive fire protection requirements, and verification of reliability without external assistance) and innovation in testing methods (such as door-opening combustion testing).

From rigorous data from the laboratory to safeguarding the lifeline of energy storage power stations, Firemana, relying on its LSFT energy storage battery module large-scale fire test platform, is leveraging technology and collaborating with industry partners to continuously push energy storage safety towards a new dimension of system-level and high reliability. The successful extreme challenge of Haichen Energy Storage is a milestone achieved through the combined efforts of platform capabilities and product design, setting a new benchmark for the safe development of the global energy storage industry.
