Hithium Innovates with Large-Scale Fire Testing
Sets new safety benchmark under rigorous testing conditions
Hithium has achieved a remarkable milestone in the field of energy storage technology by successfully completing the world’s first all open-door large-scale fire test using its advanced ?Block 5MWh battery energy storage system (BESS). This innovative test not only demonstrates Hithium’s commitment to safety but also sets a new benchmark for validation methods within the energy sector.
The Importance of Rigorous Safety Testing
In recent years, there has been increasing concern regarding safety incidents related to battery energy storage systems, particularly issues like thermal runaway. This growing anxiety underscores the urgent need for more stringent and standardized testing protocols. Understanding this necessity, Hithium developed the open-door fire test, which introduces four ultimate test challenges deliberately designed to push the system to its limits.
Key Components of the Test
The open-door fire test incorporated various extreme conditions, including:
- All open-door combustion: Keeping the container doors fully open allowed for an unrestrained combustion environment, intensifying oxygen flow—much more severe than conventional closed-door tests.
- Minimal spacing: The BESS units were placed close to each other with only a 15cm gap, testing the system’s ability to manage extreme heat. Even with flames exceeding 1300°C, there was no thermal propagation to adjacent units.
- Deactivation of fire suppression systems: The test relied exclusively on passive fire protection measures, confirming the system's autonomy to resist fire without active suppression.
- Full capacity conditions: The BESS was charged to 100% State of Charge (SOC), ensuring maximum thermal energy release and rigorously testing reliability and stability.
Test Oversight and Results
Conducted by UL Solutions, a prestigious safety certification body, the test was closely monitored by certified fire protection engineers and various stakeholders in the energy sector. Adhering to rigorous safety standards set forth by UL 9540A and NFPA 855, the test ensured comprehensive safety validation.
Remarkably, even after enduring 15 continuous hours of intensive combustion, the structural integrity of the energy storage system remained intact. There was no fire propagation to neighboring containers, showcasing Hithium's efficient multi-layered passive safety architecture and exceptional thermal isolation capabilities.
