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(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池放電(dian)(dian)(dian)(dian)(dian)后需要充(chong)電(dian)(dian)(dian)(dian)(dian)器來充(chong)電(dian)(dian)(dian)(dian)(dian)，一(yi)個(ge)良好的充(chong)電(dian)(dian)(dian)(dian)(dian)器應(ying)該能(neng)(neng)夠(gou)提供恒定電(dian)(dian)(dian)(dian)(dian)流來充(chong)電(dian)(dian)(dian)(dian)(dian)，并且在電(dian)(dian)(dian)(dian)(dian)池足時(shi)能(neng)(neng)夠(gou)自動停止充(chong)電(dian)(dian)(dian)(dian)(dian)這樣才能(neng)(neng)使電(dian)(dian)(dian)(dian)(dian)池的壽命最長。

　　在充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程中(zhong)，當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)端(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)開始下降時(shi)(—△V負(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)斜率)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)應停止(zhi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的過充會造成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)永久性(xing)損壞(huai)。在測(ce)(ce)試(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)時(shi)，可(ke)以使用真實(shi)的充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)測(ce)(ce)試(shi)，然而這種方法需要非(fei)常冗長時(shi)間(jian)，并不切實(shi)際或不符合經濟效益。當(dang)使用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子負(fu)(fu)(fu)載時(shi)，可(ke)以設(she)定為定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)負(fu)(fu)(fu)載模(mo)式，并且設(she)定所需的端(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，此時(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子負(fu)(fu)(fu)載將吸取足夠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流控制電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)穩定到設(she)定值。例如：測(ce)(ce)試(shi)1.2V的充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)設(she)定端(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)從1V、1.2V、1.4V、1.5V來測(ce)(ce)試(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流調整率，然后設(she)定 1.48V(-△V模(mo)擬(ni)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充足)來測(ce)(ce)試(shi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)是(shi)否(fou)會停止(zhi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

　　二、電池放電測試

　　任何電池均可視為(wei)一個(ge)電壓源，其(qi)儲(chu)存(cun)容量單位(wei)為(wei)mAH或(huo)AH，例如12V 6AH 的電池容量表示它在12V和(he)1A輸出時(shi)(shi)可工作六個(ge)小時(shi)(shi)。

　　測試電(dian)(dian)(dian)池(chi)的放電(dian)(dian)(dian)特性時，應(ying)該(gai)使用(yong)(yong)電(dian)(dian)(dian)子負(fu)載的定電(dian)(dian)(dian)流模式，而電(dian)(dian)(dian)池(chi)應(ying)在要求的電(dian)(dian)(dian)壓范圍內，在規格時間(jian)提供測試的電(dian)(dian)(dian)流，使用(yong)(yong)計算機或(huo)打印機來(lai)監視電(dian)(dian)(dian)池(chi)的電(dian)(dian)(dian)壓及電(dian)(dian)(dian)流。

　　定功(gong)(gong)率(lv)模式亦可用來測試電(dian)(dian)池的(de)放電(dian)(dian)特(te)性(xing)，當電(dian)(dian)子(zi)負(fu)載(zai)工作于定功(gong)(gong)率(lv)模式時(shi)，電(dian)(dian)子(zi)負(fu)載(zai)會從電(dian)(dian)池吸取所設(she)定功(gong)(gong)率(lv)值。此時(shi)電(dian)(dian)子(zi)負(fu)載(zai)的(de)電(dian)(dian)流會隨著(zhu)負(fu)載(zai)電(dian)(dian)壓的(de)降低而自動增加保持功(gong)(gong)率(lv)恒定，反之亦然(ran)。

　　三、電池充電測試

　　一般含(han)恒(heng)壓(ya)和恒(heng)流輸出(chu)的(de)(de)直流電(dian)源(yuan)(yuan)可(ke)用來對充(chong)電(dian)電(dian)池充(chong)電(dian)，或使(shi)用沒有穩壓(ya)限流的(de)(de)直流電(dian)源(yuan)(yuan)(例如(ru)簡單的(de)(de)整流與電(dian)容濾波電(dian)路)與直流電(dian)子負載串聯做(zuo)為電(dian)流源(yuan)(yuan)對電(dian)池充(chong)電(dian)，此(ci)時充(chong)電(dian)電(dian)流大小由電(dian)子負載定(ding)(ding)電(dian)流模式下的(de)(de)設定(ding)(ding)電(dian)流值決定(ding)(ding)。

　　對于電(dian)池(chi)充電(dian)器(qi)與(yu)電(dian)池(chi)的(de)測試測量就(jiu)介(jie)紹到這里(li)，希(xi)望大家(jia)都能更加深入了解(jie)電(dian)池(chi)充電(dian)器(qi)!
