摘要:

锂离子电池因其高能量密度、低放电率和长寿命等优点和卓越的电化学性能正被大规模用于各类储能系统,且储能规模日益增长,但近两年国内外锂离子电池储能电站安全事故频发、损失惨重。针对这一现状,为完善和提升国内现行的储能系统产品的安全标准,本文详细介绍了国外经典的锂离子电池储能安全标准,如IEC、UL等储能安全标准以及中国现行的储能国家标准、行业标准、团体联盟制定的储能安全相关标准等,归纳并简要分析了上述国内外储能安全标准的特点。同时,根据锂离子电池储能系统的具体测试及运行要求,着重从储能系统的结构安全要求、电池本体安全要求、环境影响要求和系统安全要求四个方面将国内储能安全标准与国外的的IEC、UL标准逐一进行了对比分析,指出了国内现行的储能安全标准的薄弱环节和不足之处。通过对储能系统锂离子电池国内外安全标准全方位的分析、比较和讨论,旨在为国内储能电站锂离子电池的安全标准的完善提出建议和实现途径,促使未来储能系统安全和高效持久运行。

Abstract:

Lithium-ion batteries are used in various energy storage systems on a large scale because of the advantages of high energy density, low discharge rate, long life, and excellent electrochemical performance. The energy storage magnitude is observed to continually increase. However, in the previous two years, safety accidents have frequently occurred in lithium-ion battery energy storage power stations at home and abroad. This study introduces foreign and domestic safety standards of lithium-ion battery energy storage, including the IEC and UL safety standards, China’s current energy storage national standards, industry standards, and energy storage safety standards set by the alliance, to improve and perfect the safety standards of the current domestic energy storage systems. This study briefly analyzes the characteristics of the energy storage safety standards established at home and abroad. Further, the storage system security requirements, battery or cell safety requirements, effects, and system safety requirements are used to analyze the operational requirements of the lithium-ion battery energy storage system, domestic energy storage safety standards, and foreign standards (IEC and UL) according to the specific tests of the lithium-ion battery energy storage system. Finally, the weaknesses and shortcomings of the current domestic energy storage safety standards are revealed. By comprehensively analyzing, comparing, and discussing the safety standards for lithium-ion batteries in energy storage systems at home and abroad, this study proposes suggestions and implementation strategies to improve the safety standards in domestic energy storage power stations to promote the safe, efficient, and long-lasting operation of future energy storage systems.
