华为数字能源圆满完成工商业构网型储能大规模燃烧测试！

Core Viewpoint - Huawei Digital Energy has successfully completed the industry's first fire safety test for commercial and industrial liquid-cooled energy storage solutions based on the latest UL9540A:2025 standard, setting a new safety benchmark for the industry [2][9]. Group 1: Extreme Testing Environment - The test created an unprecedentedly harsh environment to comprehensively validate the safety performance of the energy storage system under extreme conditions, triggering thermal runaway in 60 cells simultaneously [4]. - The testing conditions included a fully charged state of 100% SOC, the use of an open-door combustion scheme, and the shutdown of all fire protection systems to assess the system's inherent design resilience [4]. Group 2: Five-Level Protection System - Huawei's commercial energy storage solution demonstrated exceptional safety performance through an innovative five-level protection design, which includes: - Thermal insulation design between cells to slow down the spread of thermal runaway [5]. - A full metal shell capable of withstanding temperatures over 1500℃, maintaining structural integrity during a fire [5]. - A unique positive pressure oxygen-blocking and directional smoke exhaust design to effectively divert combustible materials and significantly reduce fire impact [5]. Group 3: Fire Maze Design - The energy storage cabinet features a maze structure at all sealed interfaces to effectively prevent the spread of flames [6]. - The cabinet is reinforced for fire resistance, providing comprehensive fire protection [6]. Group 4: Performance Data - Key data collected during the test demonstrated the safety and reliability of Huawei's energy storage solution, with a maximum temperature of only 45.3℃ in adjacent cells at a fire temperature of 961℃, well below the threshold for cell venting [7]. - The maximum heat release rate recorded was 3MW, with total burn time of less than 3 hours before self-extinguishing, showcasing excellent thermal management capabilities [7]. Group 5: Industry Leadership - The extreme combustion test, witnessed by TÜV Rheinland, not only validated the safety performance of Huawei's energy storage solution under extreme conditions but also provided valuable safety verification experience and templates for the industry [9]. - Huawei's energy storage system has been recognized for its leading capabilities in thermal runaway prevention and flame spread containment, further establishing a milestone for safe large-scale applications in the industry [11].
