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

In an impressive demonstration of innovation and safety, Huawei's Smart String Grid Forming Energy Storage System (ESS) has successfully passed a rigorous extreme ignition test, a significant milestone in energy storage technology. Conducted under the watchful eyes of customers and the globally recognized independent risk management organization, DNV, this test reflects Huawei's commitment to enhancing safety standards in the renewable energy sector.

Real-World Testing Environment

The extreme ignition test adhered strictly to the UL 9540A international testing standards, showcasing Huawei's readiness to tackle real-world challenges. The test involved four units of the Smart String ESS, which were configured with commercially available products. Fully charged to a 100% State of Charge (SoC), these units were deployed according to the required maintenance and safety distances, simulating conditions closely resembling their intended operational environment.

Without any manual intervention, the testing process was designed to authenticate the system's performance under extreme conditions, providing a comprehensive validation of its safety features.

Outstanding Safety Features

During the test, an attempt to induce thermal runaway in 12 of the battery cells resulted in no ignition or explosion, a stark contrast to conventional energy storage systems where a single cell failure often causes catastrophic incidents. Huawei's innovative design includes a combined defense mechanism—a pressurized oxygen barrier and dedicated smoke venting channels—that effectively manages combustible gases, ensuring that thermal incidents remain contained.

The test rigorously examined the system's behavior under maximum oxygen influx scenarios, which often precipitate rapid combustion. Despite these challenging conditions, the highest temperature recorded in adjacent units remained a mere 47 °C, well below the thermal runaway threshold. Post-test inspections confirmed the integrity of the battery housing and flame-resistant layers, proving the system's resilience.

Extended Safety Margins

One of the remarkable achievements of Huawei's Smart String ESS is its ability to delay ignition. In instances of thermal incident escalation, the system managed to postpone ignition by a remarkable 7 hours. This lag provides critical time for emergency response teams to intervene, thereby reducing the risks associated with potential accidents and enhancing overall safety for both personnel and property.

The capability to decelerate the progression of thermal incidents sets a new precedent in energy storage safety protocols, allowing for a more secure operating environment.

A New Era in Safety Protocols

This groundbreaking test results underscore Huawei's significant advancements in safety technology within energy storage systems, defining a new standard for the industry. The successful completion of these tests not only highlights the robustness of Huawei's innovative safety mechanisms but also reinforces their commitment to facilitating sustainable, high-quality renewable energy development.

As the world accelerates toward renewable energy solutions, the role of advanced energy storage systems becomes increasingly critical. Huawei's efforts in enhancing safety protocols will undoubtedly contribute to the broader adoption and trust in energy storage technologies, paving the way for a safer future in energy management.

Through architectural innovation, Huawei has elevated its energy storage safety from individual battery cells to an entire system level, making significant strides in preventing thermal runaway and ensuring system integrity under extreme conditions.
