美國家用商用電池標準UL2054 (Ed.3)第3版于2021年11月17日正式發(fā)布，此次標準較比上一版（第2版）更新的重要內(nèi)容如下：
一：Added general construction requirements for wiring and terminals; 6.3
增加線材和端子的一般結(jié)構(gòu)要求，涉及6.3章節(jié)。
當考慮到電池組內(nèi)導線可能承受的溫度、電流和電壓時，導線應該絕緣且可接受；接線頭和連接處應通過機械方式緊固，并應提供電氣接觸，且在連接和端子上沒有應力。導線應該安全，并遠離鋒利的邊緣或其他可能危及導線絕緣的部分。
標準原文：
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.
