Abstract: With the battery pack-level thermal runaway control, Huawei's fire-free energy storage system (ESS) redefines safety. [Shenzhen, China, December 24, 2024] Huawei Digital Power and TÜV Rheinland jointly completed ESS safety tests on Huawei's Smart String & Grid Forming ESS Platform (LUNA2000-4472 series and LUNA2000-215 series).
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.
In its ignition test, Huawei used four utility-scale BESS units. This was previously done by Sungrow, which in November 2024 conducted a fire test on 20 MWh of BESS. The exercise involved four liquid-cooled 5 MWh Powertitan 2.0 storage systems and came with a price tag of $4.2 million.
The manufacturer also reported a slow fault progression as one of the product's key safety features. 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.
