Core Viewpoint - The recent trend of large-scale fire tests among domestic energy storage companies is aimed at enhancing product safety credibility and meeting international standards, which is becoming a necessary requirement for entering overseas markets [1][4][5]. Group 1: Importance of Fire Tests - Energy storage companies are increasingly conducting large-scale fire tests to validate product safety and compliance with international standards, which enhances competitiveness and customer trust [3][4]. - The fire tests are costly, with expenses reaching millions, but they provide critical data for insurance participation in energy storage investments and operations [2][3]. - Successful fire tests can serve as a key endorsement for market entry, particularly in overseas markets where safety standards are stringent [3][4]. Group 2: Industry Standards and Regulations - While fire tests are not yet mandatory in China, international clients are beginning to require such certifications, indicating a shift towards making these tests a standard requirement [4][5]. - The GB/T 44026-2024 standard outlines safety requirements for energy storage systems, emphasizing the need for products to prevent fire and explosion during thermal runaway events [5][6]. - The development of industry standards is ongoing, with discussions among organizations like the American Fire Association and Canadian Standards Association to establish fire test protocols [4][5]. Group 3: Technological Advancements and Safety Improvements - Companies are adopting advanced safety designs, such as using more stable chemical systems and implementing multi-layered safety protections to minimize risks [6][7]. - The shift towards safer battery materials, such as lithium iron phosphate, is reducing the likelihood of thermal runaway incidents, contributing to overall industry safety improvements [6][7]. - Liquid flow batteries, like zinc-iron flow batteries, are recognized for their inherent safety due to their non-flammable materials and stable operating conditions [7].
