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，火烧测试在国内还没有成为强制要求。也有受访人士担忧，如果门槛一下子提得 太高，国内有能力达成条件的厂商数量不多，对于还处在成长期的储能行业并不一定有利。 (证券时报) ...

Core Viewpoint - REPT BATTERO has successfully passed a large-scale fire test for its 5MWh energy storage battery cabinet, demonstrating its ability to prevent thermal runaway and setting a new safety benchmark in the energy storage industry [21][22]. Group 1: Test Overview - The fire test involved a fully charged 5MWh battery cabinet that burned continuously for 14 hours, simulating five types of composite fire scenarios [21][22]. - The test was conducted under extreme conditions, with the battery storing maximum energy and exhibiting high chemical activity, which significantly increases the risks associated with thermal runaway [22][23]. Group 2: Testing Methodology - Ignition was triggered using a combination of internal heating and external propane flame injection, creating a realistic simulation of catastrophic accident scenarios [23]. - The test design included a rigorous setup that removed active fire suppression systems, relying solely on the battery cabinet's passive safety features to manage the fire [13][20]. Group 3: Safety Performance - The test successfully prevented the spread of thermal runaway, with the highest flame temperature reaching 1380°C while maintaining the internal temperature of adjacent battery cells below 57°C, indicating effective thermal management [7][20]. - The testing apparatus was designed to simulate the harshest fire scenarios, adhering to multiple core safety standards, including CSA/ANSI C800:25, NFPA 855, and UL 9540A [22]. Group 4: Data Collection and Analysis - Over 600 temperature monitoring points were deployed during the test, allowing for comprehensive data collection on the fire's behavior and the battery's performance [20]. - Post-test inspections revealed that the battery cabinet's structural integrity remained intact, with no collapse or significant damage, further validating the product's safety design [20].

Core Viewpoint - The article highlights the successful completion of an extreme fire test conducted by Ruipu Lanjun on its Powtrix® 5MWh energy storage battery system, demonstrating its enhanced safety performance under severe conditions [2][20]. Group 1: Testing Conditions and Methodology - The fire test was conducted under extreme conditions, simulating a worst-case scenario with a fully charged battery, which poses the highest risk of thermal runaway and fire spread [3][4]. - The test involved a combination of internal heating and external propane flame exposure, leading to a sustained burn of approximately 14 hours after a 3-hour ignition trigger [4][19]. - The test design included exposure to five types of fire (solid, liquid, gas, metal, and energized equipment), assessing the battery system's resilience against complex fire scenarios [4][10]. Group 2: Safety Performance and Results - The Powtrix® battery system successfully prevented thermal runaway from spreading to adjacent battery units, with the maximum flame temperature reaching 1380°C while maintaining the internal temperature of neighboring units below 57°C [7][20]. - The test was conducted without active fire suppression systems, relying solely on the battery's passive safety design, which proved effective in containing the fire [13][20]. - Over 600 temperature monitoring points were deployed during the test, providing comprehensive data collection and analysis of the combustion process, which received commendation from fire safety engineering experts [19][20]. Group 3: Industry Implications - This rigorous testing sets a new benchmark for safety in the energy storage industry, showcasing Ruipu Lanjun's capabilities in battery technology development and system safety design [20]. - The successful demonstration of the Powtrix® system's safety features contributes significantly to advancing the overall safety and reliability standards within the energy storage sector [20].
