" d6 ~1 e7 G. H8 [需要管控電池, 且需要指定電池的型號及廠家, 還有在Heating Test及Input Test需要用到電池, 但我的battery charger并不打算連同電池一起銷售呀, 且也目前沒有跟此battery charger搭配的電池.
請問這樣合理嗎?請大家討論下.

解決方案一. 你在申請ul60950時壓根就不要提功能是Battery Charger,申請Power Sullply就好了,因為在申請Power Sullply和Battery Charger雖然用同一個標準來評估,但是針對不同用法要求是不一樣的;
解決方案二. 如果你一定要以Battery Charger來申請,那是一定要管控電池型號規格的了,同時輸出端需加极性保護,好像可以不控制廠家的,這點你可以和認證公司溝通一下應為可行的.

一般来说Battery Charger是以申请UL1310 or UL1012为主，但若一定要申请UL 60950-1，则会依照PAG的要求，是必须控制锂电池的厂家型号，其他类的充电电池会控制规格，并且需搭配电池做测试

prince

經跟UL工程師討論, 最終需要在Label及使用手冊中管控電池的廠家及型號, 但電池必須是UL 2054的Listing的電池.

yishenger

充电器嘛，在使用说明书或铭牌中当然要写明适用的电池信息啦，电池型号那么多，消费者不知道，那就要写明是什么厂家生产的什么型号的电池了。这样防止用户随便给不适用电池充电带来危险。

prince

我覺得這個問題有爭議, 因為我們再做ATX Power時也不會去考量它最終會用在何種環境下,如果到時發生了問題這樣的責任也很難劃分是ATX Power的問題還是其它PC里面的零件問題.那么這個也跟battery charger不搭配電池銷售一樣.

jackie

ATX Power是属于半成品类，最终还是要与系统再做评估，与充电器的状况是不一样的

那我們的筆記本用的Adapter也可以給電池充電, 但我們也不會去評估這顆Adapter是否會搭配何種電池.

但是给笔记本或手机申请时那个电源并没有写明是充电器，而是写电源适配器。
