現有一款battery charger在申請UL 60950-1時, UL說根據Practical Application Guidelines for

DESCRIPTION OF ISSUE:
Type of Issue: Technical/Certification
What are the construction and performance requirements for battery chargers (with battery
9 `  E. u8 D# V9 kpacks) when the battery charger is evaluated under the Standard as part of either an end
product investigation or part of an Accessory Listing investigation?
! J. F  O5 u8 r: f: Y9 dAPPLICATION GUIDELINE:
& X  h5 ~) m+ w' IThe following are general construction and performance guidelines.
Construction: The following considerations should be given to battery chargers (and packs)
during the construction evaluation.
a. A marking should be provided on the battery charger indicating the specific model

b. The charger should be marked to indicate the battery pack (mfg./type/rating) for
which the battery charger is to be used;

Follow-up Procedure.
Performance: The following considerations should be given to the performance test program

(C1) Test should be conducted on the transformer that supplies the charging circuit.
d. An Abnormal Operation Test program (per Sub-clauses 4.3.8 and 5.3.6) should be
designed anticipating possible foreseeable fault conditions, including a short circuit of

Battery chargers evaluated under this Standard introduce some unique considerations into

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.
$ h; P( |3 v% T1 m% V1 g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;
. f& l$ a1 J* ^4 b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。
