電池充電器正式投入市場之前一定會會進行各種測試，例如放電測試與充電測試，今天我們一起來看一下電池充電器與電池的測試測量!

　　一、電池充電器測試

　　充電(dian)電(dian)池(chi)(chi)放電(dian)后需要(yao)充電(dian)器(qi)來充電(dian)，一個(ge)良好的充電(dian)器(qi)應該能夠提供恒定電(dian)流來充電(dian)，并且在(zai)電(dian)池(chi)(chi)足時能夠自動停止(zhi)充電(dian)這樣才(cai)能使電(dian)池(chi)(chi)的壽命最長(chang)。

　　在充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程中，當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓開(kai)始(shi)下降時(—△V負電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓斜率)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器應停止充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)過充(chong)(chong)(chong)會造成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)永久性(xing)損壞(huai)。在測(ce)試(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器時，可(ke)以使(shi)用(yong)真實的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)測(ce)試(shi)，然而這種方法需(xu)要非(fei)常(chang)冗長時間，并不(bu)切實際或(huo)不(bu)符合經濟效(xiao)益。當使(shi)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子負載(zai)時，可(ke)以設定為定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓負載(zai)模式，并且設定所需(xu)的(de)(de)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，此時電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子負載(zai)將(jiang)吸取足(zu)夠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流控制電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓穩定到設定值。例如(ru)：測(ce)試(shi)1.2V的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)設定端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓從1V、1.2V、1.4V、1.5V來測(ce)試(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流調整率，然后(hou)設定 1.48V(-△V模擬電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)足(zu))來測(ce)試(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器是否會停止充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

　　二、電池放電測試

　　任何電池均(jun)可視為一個電壓源，其儲存容(rong)量單位為mAH或AH，例如12V 6AH 的電池容(rong)量表示它在12V和1A輸出時可工作六(liu)個小時。

　　測(ce)試電(dian)(dian)池的(de)放電(dian)(dian)特性(xing)時(shi)，應該(gai)使用(yong)電(dian)(dian)子負載(zai)的(de)定電(dian)(dian)流(liu)模(mo)式，而電(dian)(dian)池應在(zai)要(yao)求的(de)電(dian)(dian)壓(ya)范圍內，在(zai)規格時(shi)間提供測(ce)試的(de)電(dian)(dian)流(liu)，使用(yong)計(ji)算(suan)機(ji)或(huo)打印機(ji)來監視電(dian)(dian)池的(de)電(dian)(dian)壓(ya)及電(dian)(dian)流(liu)。

　　定功率(lv)模式亦(yi)可用(yong)來測試電(dian)池的(de)放電(dian)特性(xing)，當電(dian)子負(fu)載(zai)工作(zuo)于定功率(lv)模式時(shi)，電(dian)子負(fu)載(zai)會從電(dian)池吸取(qu)所設(she)定功率(lv)值。此時(shi)電(dian)子負(fu)載(zai)的(de)電(dian)流會隨(sui)著負(fu)載(zai)電(dian)壓(ya)的(de)降低而自動增加保持(chi)功率(lv)恒定，反之亦(yi)然。

　　三、電池充電測試

　　一(yi)般(ban)含恒壓和恒流(liu)(liu)輸出的直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)可用(yong)來對(dui)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)，或(huo)使(shi)用(yong)沒有穩(wen)壓限(xian)流(liu)(liu)的直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(例如(ru)簡單的整(zheng)流(liu)(liu)與電(dian)(dian)(dian)(dian)(dian)容濾波電(dian)(dian)(dian)(dian)(dian)路)與直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)子負載串聯做為電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)源(yuan)對(dui)電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)，此時充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大小由電(dian)(dian)(dian)(dian)(dian)子負載定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)模式下的設定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)值(zhi)決定(ding)(ding)。

　　對于電(dian)池充電(dian)器與電(dian)池的測(ce)(ce)試測(ce)(ce)量就介(jie)紹(shao)到這里，希望大(da)家都能更(geng)加深入了解(jie)電(dian)池充電(dian)器!
