Huawei's Innovative ESS Achieves Milestone in Safety Testing

In a significant advancement for energy storage technology, Huawei Digital Power has announced that its Smart String & Grid Forming Energy Storage System (ESS) has passed an extreme ignition test with flying colors. This test, which was observed by global customers and DNV, a renowned independent organization specializing in assurance and risk management, underscores Huawei's commitment to safety in the renewable energy sector.

Real-World Validation Under Duress

Conducted under conditions that mimicked real-world applications, the test assessed four actual mass-produced units of the ESS. These units were charged to a full state of charge (SOC) and deployed following the strictest maintenance and safety protocols applicable to energy storage installations. Notably, the entire testing procedure occurred spontaneously, requiring no manual intervention, thereby creating a robust system-level verification environment that accurately reflected potential operational scenarios in the field.

Groundbreaking Safety Features

One of the most impressive outcomes of the extreme ignition test was the performance of Huawei's ESS when 12 cells underwent thermal runaway. Typically, such a situation in conventional energy storage systems can lead to fires or explosions. However, in Huawei's Smart String ESS, this did not occur. The system's innovative safety features functioned effectively, employing a positive pressure oxygen barrier and a directional smoke exhaust duct to manage the release of combustible gases. Even after multiple ignition attempts, there was no fire or explosion, showcasing the system’s capacity to contain fires and prevent issues from propagating.

Exceptional Heat Resistance

The extreme ignition test was designed to challenge the ESS in every possible way, simulating scenarios with escalating numbers of thermal runaway cells under maximum oxygen supply. Despite these rigorous conditions, the nearby containers only reached a maximum temperature of 47°C, well below the critical threshold for thermal runaway. Post-test evaluations confirmed that the integrity of the battery packs and the internal fire-resistant structures was uncompromised, emphasizing the ESS's robustness against severe conditions.

Time for Critical Intervention

A notable distinction of Huawei's ESS during the testing was its slow fault progression, providing valuable time for early intervention in case of emergencies. Unlike conventional systems, where thermal runaway events can lead to immediate hazards, Huawei's Smart String ESS delayed ignition for up to 7 hours, allowing emergency responders to act effectively and mitigate any potential risks to safety and property.

Redefining Safety Standards in the Energy Sector

This achievement marks a pivotal moment in redefining safety standards for energy storage systems. The successful testing of Huawei's Smart String ESS illustrates a significant breakthrough in assuring safety from the battery cell level to the system as a whole. By enhancing the safety mechanisms via architectural innovation, Huawei is set to lead the charge toward industry-standard practices prioritizing sustainable and high-quality advancements in the renewable energy market.

The implications of such advancements extend beyond just technological innovation. They offer enhanced assurance for stakeholders across the energy sector, promising a more secure approach to energy storage solutions amid the escalating demand for renewable energy resources worldwide. As Huawei builds on this momentum, the company aims to continue setting new benchmarks, facilitating safer and more effective energy storage capabilities for a sustainable future.
