Huawei's Smart String Energy Storage System Triumphs in Extreme Ignition Tests

In a significant milestone for energy storage technology, Huawei Digital Power has successfully demonstrated the safety and reliability of its Smart String and Grid Forming Energy Storage System (ESS). The solution recently passed a rigorous ignition test conducted under extreme conditions, validating its capabilities to handle critical situations without compromising safety.

Understanding the Test

The test was performed in collaboration with DNV, an independent, globally recognized risk management and quality assurance service provider. This groundbreaking evaluation emphasized Huawei's strong commitment to enhancing safety measures within the energy storage sector. The method employed adhered to the international standard UL 9540A, which governs the safety of energy storage systems.

Real-World Testing Conditions

The evaluation involved four mass-produced Smart String ESS setups that were fully charged before commencing the test. This realistic approach ensured that all conditions reflected actual usage scenarios without requiring manual intervention, thus mirroring a real-world operational environment.

Safety Mechanisms at Play

One of the most crucial aspects of this test was examining the thermal runaway phenomenon, where a single cell failure can lead to cascading issues within an energy storage system, potentially causing fire or explosion risks. Surprisingly, during the test, twelve individual cells experienced thermal runaway without resulting in fires or explosions. This reliability can be attributed to a groundbreaking safety feature employed by Huawei—an oxygen barrier under positive pressure and a directed smoke venting channel effectively managed gases generated from combustion.

Effective Fire Prevention Measures

To simulate worst-case scenarios, the testing protocol progressively increased the number of cells facing thermal runaway while ensuring maximum oxygen supply to foster combustion. Remarkably, the temperature of adjacent battery packs in other containers reached only 47 degrees Celsius, indicating that the fire prevention measures in place were effective even under duress.

Slow Failure Response for Enhanced Safety

Conventional energy storage systems often face immediate fire hazards upon a single cell's thermal runaway. In contrast, Huawei’s Smart String ESS exhibited a slow failure response, allowing up to seven hours before igniting, even as the number of compromised cells increased. This delay provides operational teams ample opportunity to execute preventive measures, guaranteeing the safety of personnel and assets in case of emergencies.

Revolutionizing Energy Storage Safety Standards

The successful completion of this extreme ignition test highlights a pivotal breakthrough in safety standards for energy storage systems. This achievement showcases Huawei’s dedication to developing comprehensive protection mechanisms that operate from the cell level to the entire system. By enhancing the architectural safety mechanisms, Huawei has effectively set a new standard in the industry, assuring the protection of critical infrastructures in various applications of energy storage.

In conclusion, the triumph of Huawei's Smart String and Grid Forming ESS in extreme ignition tests not only emphasizes the innovative approach the company takes towards energy safety but also serves as an industry benchmark for future developments in the renewable energy landscape.
