World's first all open-door large-scale fire test of 5MWh battery system completed
A Chinese energy storage technology firm has completed the world's first all-open-door large-scale fire test of its ∞Block 5MWh battery energy storage system (BESS). The test conducted on Hithium energy storage device offers a high-stakes technical model to inform future product safety standards and set a validation benchmark in this revealed that as thermal runaway and other safety incidents in BESS draw increasing concern, more rigorous and standardized safety testing is urgently needed. The open-door fire test was developed to meet this requirement—featuring four ultimate test challenges that are all open-door combustion, dual 15cm extreme spacing, fire suppression system deactivated, and 100% State of Charge (SOC).The test strictly adhered to UL 9540A, NFPA 855 safety standards and was conducted by UL Solutions, a globally recognized safety certification authority, and witnessed by certified U.S. fire protection engineers and customers. The system structure remained intact, with no fire propagation to any of the three adjacent containers despite undergoing 15 hours of full combustion. This result validates Hithium's multi-layered passive safety architecture and thermal isolation capabilities, even under the most extreme conditions, according to a press revealed that during all open-door combustion, the container doors remained fully open throughout the test, creating an unrestrained combustion environment with intensified oxygen flow—far more severe than traditional closed-door the dual 15cm extreme spacing test, the BESS were placed side by side and back to back with just 15cm spacing. Despite flames over 1300°C, no thermal propagation occurred, proving effective close-range isolation. In one of the tests, all fire suppression systems were deactivated. The system relied solely on passive fire protection to withstand prolonged intense fire, demonstrating autonomous fire resistance and BESS was tested at full capacity to maximize thermal energy release, validating the system's reliability and stability under the harshest conditions. Hithium stressed that the latest achievement highlights HiTHIUM's commitment to innovation and quality, providing valuable insights for future safety standards in the industry. "Moving forward, Hithium will continue to advance safety performance through technology leadership and global collaboration, driving the industry toward a safer and more reliable future," said the company in a statement. Industry experts hailed the trial as a 'qualitative leap' in energy storage fire safety testing, significantly increasing difficulty across fire dynamics, spatial constraints, charge state, and response conditions. The results not only enhance the credibility of safety claims but offer a replicable framework for establishing more practical, real-world safety benchmarks, reported PV Magazine. Hithium ranked 4th globally in energy storage battery shipments in 2024, delivering 35.1 GWh, according to Infolink's latest market data.

SNEC 2025｜Hithium Defines a New Benchmark for Energy Storage Safety with the World's First All Open-Door Large-Scale Fire Test
SHANGHAI, June 13, 2025 /PRNewswire/ -- On June 11, 2025, at the 18th SNEC, Hithium, a leading global energy storage technology company, held a product safety technology sharing event themed Leading the Future, Forged for Safety and unveiled the full results of the world's first all open-door large-scale fire test of its ∞Block 5MWh energy storage system, and was also awarded the large-scale fire test certification by international testing authority UL Solutions. Hualei Wang, project manager for the fire test, shared an overview of the test background and key details. A video of the open-door fire test was also shown on-site, offering a comprehensive view of the test procedure, technical highlights, and results. The open-door fire test was initiated by intentionally heating eight battery cells inside container A to trigger thermal runaway, causing propagation between cells. As the battery's pressure relief vents opened, an ignition system ignited the released gases, initiating full combustion with the container doors kept wide open to allow continuous oxygen flow. This setup maximized heat exposure to adjacent containers B, C, and D. The test was conducted under four extreme conditions: all open-door combustion, dual 15 cm extreme spacing, fire suppression system deactivated, and 100% State of Charge (SOC). Peak Fire Phase: At the fourth hour of testing, the fire reached its peak temperature of 1,372°C. Temperature monitoring confirmed that cell temperatures in all adjacent containers remained well below the cell thermal runaway initiation threshold defined by the UL9540A cell-level test (≤42°C in Container B, ≤80°C in Container C, and ≤70°C in Container D). Sustained Combustion Phase: After 15 hours of combustion, the open flame was extinguished. The initiating container remained structurally intact without deformation or collapse. No combustion or thermal runaway propagation occurred in the three adjacent containers. Containers B, C, and D only experienced minor surface damage, while internal battery modules remained completely unaffected. The completion of the test was made possible by Hithium's multi-layered safety architecture, spanning the cell, module, and system levels. At the cell level, heat-resistant anode/cathode materials, functional electrolyte additives, and high-temperature separators raised thermal thresholds. At the module level, low-conductivity insulation and flame-retardant top covers minimized propagation risk. At the system level, a high-strength container frame and heat-resistant enclosure materials maintained structural stability under extreme heat. At the event, UL Solutions awarded Hithium a certification for the large-scale fire test, recognizing its compliance with UL 9540A and NFPA 855 standards. Qifeng Xiao, General Manager of the Energy and Automation Division, Asia Pacific at UL Solutions, stated at the certification ceremony, "Hithium's pioneering open-door extreme fire test was the first to be conducted under full oxygen exposure—far beyond the industry standard closed-door with explosion vent fire test model. The positive outcome not only validated the system's self-contained fire protection, but also established a valuable reference for the development of global energy storage safety standards through the world's first open-door fire test." This pioneering fire test not only demonstrated Hithium's strong technical capabilities but also reflected its full confidence in the safety performance of its energy storage systems through a fully transparent testing process, contributing important data and practices to the industry. Hithium will continue to invest in safety innovation—tightening the "seatbelt" for the global transition to green energy.

Chinese battery maker Hithium expands global footprint amid US-China rift, rising demand
Xiamen Hithium Energy Storage Technology, the world's third-largest energy storage system (ESS) battery manufacturer, is ramping up production overseas in response to heightened US-China tensions and rising tariffs impacting Chinese exports. Hithium plans to start production at its Texas factory in the second half of this year and hire at least 200 staff locally, said Sun Minghuang, the director of strategic marketing, in an exclusive interview. 'We are determined to go global, and localisation is a very important strategy in our global ambitions,' he said. Hithium filed its Hong Kong listing application in March to raise funds for its growth plans. The company's US$100 million facility in Forney, Texas, covering nearly 500,000 sq ft, will have an annual production capacity of about 10 gigawatt-hours (GWh). Accounting for at least 10 per cent of Hithium's total production capacity, the company was targeting to more than double its capacity to 100GWh by 2026 from 2024 levels, according to its preliminary prospectus. Xiamen Hithium engineers inspect one of the company's facilities. Photo: Handout Hithium aims to generate half of its annual revenue overseas by 2028, from nearly 30 per cent last year, taking advantage of growing demand for energy storage due to increasing renewable energy production, according to Sun. Earlier this month, the company signed a preliminary agreement with Spanish venture capital firm GCRPV to set up an ESS plant in Europe. In October, it formed a joint venture with a Saudi Arabian firm to set up a facility in the Middle Eastern country.
