释放3大信号！海辰储能千安时大电芯系统全球第一烧

Core Viewpoint - The article emphasizes the significance of large-scale fire testing for energy storage systems, particularly the 6.25MWh long-duration storage system, as a critical safety validation step for the industry [2][3][5]. Group 1: Testing and Safety Validation - The large-scale fire test conducted by Haicheng Energy for the 6.25MWh long-duration storage system is the first of its kind globally, marking a key milestone in safety verification for next-generation energy storage systems [3][4]. - The test adhered to the latest standards of UL 9540A 2025 and NFPA 855-2026, demonstrating that the high-energy density system exhibited stable and controllable safety performance under extreme conditions [2][5]. - The testing conditions included extreme scenarios such as "full open burning" and "maximum spacing," which provided important practical references for the industry's fire testing evolution [5][9]. Group 2: Industry Implications - The successful fire test signals that large-capacity cells may enter a period of centralized validation, addressing industry concerns regarding safety during thermal runaway events [11][13]. - The test fills a significant gap in safety verification for lithium battery long-duration storage systems, providing crucial data to support the commercial application of 4-hour and longer storage solutions [14]. - The results indicate that safety is becoming a core competitive signal in the energy storage industry, shifting the focus from cost competition to technological and safety advancements [15][19]. Group 3: Safety Design Innovations - Haicheng Energy's innovative safety design includes a multi-layered safety protection system that effectively manages thermal runaway risks, ensuring that high-temperature gases are quickly vented to prevent explosions [16][18][21]. - The structural integrity of the storage system was maintained during the test, with no deformation or collapse observed, demonstrating the effectiveness of the fire isolation and heat insulation measures [9][21]. - The design philosophy emphasizes a comprehensive safety approach that integrates cell, module, and system-level protections, establishing a benchmark for safety in the energy storage sector [18][19].
