"储能企业开展火烧测试的意义，在于通过极限验证提升产品安全可信度，为市场准入提供关键背 书。"中关村储能产业技术联盟副秘书长、标准总监唐亮在接受记者采访时谈到，火烧测试的价值一是 验证产品安全设计的有效性，二是为进入海外市场提供试验数据，验证其国际标准合规性，三是提升企 业竞争力与客户信任度，第四点则是若测试未达预期，企业需重新优化设计。 阿特斯储能相关负责人认为，储能系统的国际认证标准中有针对各个层级、模拟各种场景的安全验证， 而烧舱测试则是通过模拟极端场景，直接验证储能系统在单体热失控并充分燃烧的情况下，产品隔热、 耐火、防爆，防止灾害进一步蔓延的能力。"这是对产品安全设计的终极检验。" 过去两个月，远景储能、阿特斯等国内储能厂商陆续发布了自家储能系统产品的烧舱测试（下称"大规 模火烧测试"）结果，更早之前，阳光电源、天合储能等也已完成这一测试。据不完全统计，目前，至 少已有11家储能企业开展了大规模火烧测试。 据了解，火烧测试一次花销达上千万元，成本不菲。受访人士认为，如果通过测试，将是企业技术实力 的直接体现，有助于在市场竞争中高筑"城墙"。 目前，部分海外客户已经要求企业提供相关测试证明，不过，火烧 ...

Core Viewpoint - The article emphasizes the importance of safety in the rapidly growing global energy storage industry, highlighting the extreme testing conducted by leading companies to validate the safety performance of their energy storage systems under severe conditions [1]. Group 1: Sunlight Power - Sunlight Power conducted the world's first large-scale combustion test of its PowerTitan1.0 system in June 2024, followed by a significant investment of 30 million for the PowerTitan2.0 test in November 2024 [1]. - The PowerTitan2.0 system withstood 25 hours and 43 minutes of continuous burning, demonstrating its robust protective capabilities and preventing fire spread [2]. - During extreme conditions, the system maintained structural integrity and prevented heat propagation, showcasing its excellent fire resistance and impact performance [3]. Group 2: BYD Energy Storage - BYD's MC Cube energy storage system underwent testing in December 2024, adhering to CSA TS-800 large-scale fire testing standards [6]. - The test revealed that while the internal temperature exceeded 1000℃, adjacent battery cabinets remained below 60℃, confirming the system's effective fire isolation design [6]. - The MC Cube demonstrated outstanding fire resistance and structural integrity, preventing fire spread and ensuring safety for personnel and the environment [6]. Group 3: Huawei Digital Energy - Huawei's intelligent string-type energy storage system was tested in December 2025, following international UL9540A standards with increased thermal runaway cell counts [7]. - The system effectively managed a scenario with 12 cells experiencing thermal runaway, utilizing innovative pressure and smoke management mechanisms to prevent combustion [8]. - The test confirmed the system's ability to maintain low temperatures in adjacent units, demonstrating its safety under extreme conditions [8]. Group 4: Hichain Energy Storage - Hichain's ∞Block 5MWh system was tested in June 2025 under UL9540A and NFPA855 standards, with open cabinet conditions to simulate extreme fire scenarios [9]. - The system successfully prevented heat propagation between cabinets even at temperatures exceeding 1300℃, validating its thermal isolation capabilities [10]. - The test confirmed the system's reliability and high safety standards without external fire protection [11]. Group 5: Canadian Solar - Canadian Solar's SolBank 3.0 system was tested in June 2025, adhering to CSA TS-800 standards for large-scale fire testing [12]. - The test demonstrated that the SolBank 3.0 effectively contained fire within the target unit, showcasing its superior passive fire protection design [13]. Group 6: Kelu - Kelu's Aqua C2.5 5MWh liquid-cooled energy storage system was tested in June 2025, following CSA TS-800 standards [14]. - The test involved a 59-hour continuous burn, with the internal temperature reaching 1300℃, yet the system maintained structural integrity and functionality [17]. - The Aqua C2.5 effectively prevented thermal runaway between units, proving its scalability for large energy storage stations [17]. Group 7: Ruipu Lanjun - Ruipu Lanjun's Powtrix® battery cabin was tested in June 2025 under CSA TS-800 extreme safety testing [18]. - The system endured approximately 14 hours of burning under severe conditions, demonstrating exceptional safety and reliability [18]. Group 8: Trina Storage - Trina's Elementa energy storage cabinet was tested in September 2024, following guidelines from the China Academy of Building Research [19]. - The test validated the effectiveness of the fire suppression systems and the overall safety of the energy storage design, with no signs of re-ignition after 24 hours [21].
