我们的产品是一个3000W 的BBU 跟PSU 连接在一起，当PSU 通电的时候,PSU 给BBU 充电。当PSU 断电的时候，BBU 给PSU 提供DC，最终输出给系统供电。 . ^) M* ^0 k$ |* k我们纠结到底是用UL1973 还是UL2054 。我觉得是用UL2054 但是客户说要做UL1973 ; r+ b. s5 o/ c, YUL1973 0 K; I& y' u# o/ a1.1 These requirements cover electric energy storage systems as defined by this standard for use as % q0 |% V+ ~9 zenergy storage for stationary applications such as for PV, wind turbine storage or for UPS, etc. . d!

我覺得UL 會跟你說要做UL1973, 有答對嗎?? 作者: 食蕉蕉啦你 时间: 2018-1-11 21:35

UL2054 主要是家用和商用的电池包，UL1973 最新版连标准名称都改了，主要是储能 5 ?9 ~8 s3 F8 y6 E! f" F( ^2 Y0 x . b3 u. k9 W. F; c3 I! n( C! @像3000W的BBU，机构一般不接受做UL2054的. S, b; J, d8 N& H9 _5 {+ v

从认证角度看，如果终端是要做950/62368， 理论上，有下面两条路可选： 9 c% i: n( S* U! _& q1. UL2054 + IEC62133； 6 b$ F3 B9 Z: A( n9 H- [7 q2. UL1973, k3 E0 ?4 Y! ^/ T

UL1973的费用贼贵，一般客户都是想方设法选用方法一，很少有客户选用方法二。UL1973 一旦扯入UL991和UL1998的软件评估，费用周期等等还得再翻翻。。。。。。。作者: Berryang 时间: 2021-8-7 12:41
做了62133 ，为啥还要做2054？？
