随着储能行业的发展和实现“双碳”目标（碳达峰与碳中和）的背景下，锂离子电池系统得到了广泛应用。对锂离子电池系统进行功能安全评估变得至关重要，不同的储能系统标准对锂离子电池系统的功能安全要求存在差异。实现不同标准之间差异的覆盖或统一，是困扰众多储能行业研发人员的一大拦路虎。本文先介绍了目前多个电力储能标准对锂离子电池系统功能安全的要求，如全球性储能系统用锂离子电池系统标准IEC 62619、北美储能系统用锂离子电池系统标准UL 1973、德国储能系统用锂离子电池系统标准VDE-AR-E 2510-50、中国电力储能用电池管理系统标准GB/T 34131，然后比较和分析这些标准之间的差异，最后总结通用方法，以实现标准之间差异的覆盖或统一。

With the gradually booming development of the energy storage industry and the background of the "Double Carbon"(carbon peaking and carbon neutrality goals) target, lithium ion battery systems are widely used as energy storage systems, the functional safety assessment of lithium ion battery systems is the most important one of them, but there are different functional safety requirements for lithium ion battery system in different electrical energy storage standards. Achieving the coverage or unification of differences between different standards is a big challenge for many R&D engineers in electrical energy storage industries. In this paper, we first introduced the functional safety requirements for lithium ion battery system from several current electric energy storage standards, such as global lithium ion battery system used in storage system standard IEC 62619, North American lithium ion battery system used in energy storage system standards UL 1973, Germany lithium ion battery s ystem used in energy storage system standard VDE-AR-E 2510-50, Chinese standard for battery management systems for electric energy storage GB/T 34131, then compared and analyzes the differences among them, and finally summarizes the general methods to realize the coverage or unification of the differences between the above standards.
