Does Huawei Digital Power's Smart string & grid forming energy storage system pass an ignition test?

Huawei Digital Power’s Smart String & Grid Forming Energy Storage System (ESS) has successfully passed an extreme ignition test in the presence of customers and Norway-headquartered independent assurance and risk management provider DNV.

What is Huawei digital power?

Huawei Digital Power is dedicated to enhancing the safety and stability of renewable integration by combining digital and power electronics technologies, leveraging technical experience, and collaborating with global power companies, grid enterprises, and electricity providers.

Does Huawei ESS delay fire ignition?

The test showed that Huawei’s ESS (container A) delayed fire ignition for seven hours in extreme scenarios, even as the number of thermal runaway cells increased. Such delayed propagation would allow emergency personnel time for early intervention, mitigating risks for personnel and property.

What is a thermal runaway in Huawei ESS (container a)?

In real-world safety incidents, it is often a single cell that leads to the release of combustible gases in the container, potentially resulting in fire or explosion. However, in Huawei’s Smart String & Grid Forming ESS (container A), thermal runaway was initiated in 12 cells without an incident.

How safe is Huawei ESS?

Post-test disassembly confirmed the integrity of the ESS body, fire-resistant layer, and internal battery packs, Huawei said. The manufacturer also reported a slow fault progression as one of the product’s key safety features.

Does Huawei smart string & grid forming ESS (container a) combustible gases?

However, in Huawei’s Smart String & Grid Forming ESS (container A), thermal runaway was initiated in 12 cells without an incident. The system’s combined defense mechanism—positive pressure oxygen barrier and directional smoke exhaust duct—effectively vented combustible gases, the manufacturer reported.
