"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 ...
