  美国家用商用电池标准UL2054 (Ed.3)第3版于2021年11月17日正式发布,此次标准较比上一版(第2版)更新的重要内容如下:
 
 
  更新一:
 
  Added general construction requirements for wiring and terminals; 6.3
 
  增加线材和端子的一般结构要求,涉及6.3章节。
 
  当考虑到电池组内导线可能承受的温度、电流和电压时,导线应该绝缘且可接受;接线头和连接处应通过机械方式紧固,并应提供电气接触,且在连接和端子上没有应力。导线应该安全,并远离锋利的边缘或其他可能危及导线绝缘的部分。
 
  标准原文:
 
  6.3.1 Wiring shall be insulated and acceptable for the purpose, when considered with respect to temperature, current, and voltage to which the wiring is likely to be subjected within the battery pack.
 
  6.3.2 The wiring splice or connection shall be mechanically secured and shall provide electrical contact without strain on connections and terminals. Wiring shall be secured and routed away from sharp edges or other parts that may compromise wiring insulation.
 
  更新二:
 
  Made miscellaneous revisions throughout the Standard; Sections 2–5, 6.1.2– 6.1.4, 6.5.1, 8.1, 8.2, 11.10, 12.13, 13.3, 14.7, 15.2, 16.6, Section 23 title, 24.1, Appendix A.
 
  对整个标准进行了杂项内容的修订,涉及章节:2–5, 6.1.2–6.1.4, 6.5.1, 8.1, 8.2, 11.10, 12.13, 13.3, 14.7, 15.2, 16.6, Section 23 title, 24.1, Appendix A此类别主要是修订标准中的描述,调整条款顺序等,标准条款内容无实质性变化。
 
  更新三:
 
  Clarified requirements for adhesive labels; Section 29, 30.1, 30.2
 
  明确不干胶标签的具体要求,涉及章节:29, 30.1, 30.2
 
  30.1 The markings required for compliance to this standard shall be legible and permanent such asetched, adhesive labels, etc. An adhesive-backed label shall comply with the requirements in UL 969, forthe intended exposure conditions and surface adhered to.
 
  29标签性能测试:基本等同于IEC/UL 62368-1中的标签擦拭测试。
 
  30.1:对于预期的暴露条件和粘贴的表面,不干胶标签需要符合UL969的要求。
 
  Exception: Adhesive labels may be alternately evaluated to the Label Permanence Test in Section 29.
 
  例外:不干胶标签可以按照第29章规定的标签耐久性测试进行替代评估。
 
  更新四:
 
  Made Limited Power Source Test an optional requirement: 7.1.
 
  LPS测试作为可选要求,涉及章节:7.1
 
  7.1 b) Section 15, Limited Power Source Test, is an optional requirement only carried out upon manufacturer’s request 7.1.
 
  7.1 b) 第15章节LPS测试,是一个可选要求,仅当制造商提出要求时才进行测试。
 
  更新五:
 
  Clarified the external resistance in the test in 11.11.
 
  明确11.11章节短路测试的阻抗要求。
 
  11.11 One of the above five test sample battery packs, tested at 20 ±5 °C (68 ±9 °F) shall be evaluated with the following additional conditions in place. The terminals are to be subjected to a short circuit condition with a resistance that is capable of withstanding the short-circuit current and creating a short circuit condition with a total external resistance of 80 ±20 mΩ. The test is to be conducted on a tissue paper covered soft wood surface and the sample battery pack and bare conductor is to be covered with a single layer of cheesecloth.
 
  变更前:
 
  5个样品中的1个样品,在20±5°C条件下,用一根至少16AWG的裸铜线短路电池的端子,未明确裸铜线的阻抗。
 
  变更后:
 
  取消裸铜线的要求,明确短路回路阻抗为80±20mΩ。
