請教大家如何利用下列對PS501方案進行測試(具體在哪些測試點的地方需要用到哪些儀器)?
示波器(電流探棒);
紋波測試儀;
模擬負載機.
小妹先在此謝過了!
求助:電源保護板PS501方案中在那些地方需要測試?

通常都要做如下測試.沒有點時間同耐性,你的PACK做出來就問題多多.聽說PS501好象有問題不知是不是真的.

夠詳細的了,不過做完這樣的測試的時候時間已經過了n多天了,如cycle life 、self discharge 都是耗時間的主
電池包的測試基本上需要包括兩個方面,一個是單體測試 , 也就是對電池進行單獨的測試,如保護功能、參數準度之類的;二個是配合系統,就是筆記本EC部分,進行測試.
每一個方面的測試都應當包括老化、電子設定、環境、安規、EMC等單獨的子項目,每一個項目下面再細分.

老大厲害啊.microchip現在在主推ps501,前幾天microchip還邀請客戶辦了個培訓,就是講ps501的設置問題.ps501的設置很多,很麻煩的,需要精通.ps501的測試設備已經由第三方公司開發出來了,具體你可以詢問microchip.
