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)電(dian)(dian)池(chi)放(fang)電(dian)(dian)后需要充(chong)電(dian)(dian)器(qi)(qi)來(lai)充(chong)電(dian)(dian)，一個良好的(de)充(chong)電(dian)(dian)器(qi)(qi)應該能夠(gou)(gou)提供恒(heng)定電(dian)(dian)流來(lai)充(chong)電(dian)(dian)，并且在電(dian)(dian)池(chi)足(zu)時能夠(gou)(gou)自(zi)動停止充(chong)電(dian)(dian)這樣才(cai)能使電(dian)(dian)池(chi)的(de)壽命最長。

　　在充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程中，當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)端(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓開始下(xia)降時(shi)(—△V負電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓斜率)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)應(ying)停(ting)止充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的過充(chong)(chong)會(hui)造成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)永久(jiu)性損壞。在測(ce)試(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)時(shi)，可(ke)以(yi)使用真實(shi)(shi)的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)測(ce)試(shi)(shi)，然而這種方(fang)法需要非常冗長時(shi)間，并不切實(shi)(shi)際或不符合經濟效益。當(dang)使用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)負載(zai)(zai)時(shi)，可(ke)以(yi)設(she)定(ding)(ding)為定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓負載(zai)(zai)模式，并且(qie)設(she)定(ding)(ding)所需的端(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，此時(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)負載(zai)(zai)將(jiang)吸取足(zu)夠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)控制電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓穩定(ding)(ding)到設(she)定(ding)(ding)值。例如(ru)：測(ce)試(shi)(shi)1.2V的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)設(she)定(ding)(ding)端(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓從1V、1.2V、1.4V、1.5V來測(ce)試(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)調(diao)整率，然后(hou)設(she)定(ding)(ding) 1.48V(-△V模擬電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)足(zu))來測(ce)試(shi)(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)是否會(hui)停(ting)止充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

　　二、電池放電測試

　　任何(he)電池均可(ke)視(shi)為一個電壓源，其(qi)儲(chu)存容量單位為mAH或AH，例如12V 6AH 的電池容量表示它在12V和1A輸出(chu)時可(ke)工作(zuo)六個小時。

　　測(ce)試(shi)電(dian)(dian)(dian)(dian)池(chi)的(de)放電(dian)(dian)(dian)(dian)特性(xing)時(shi)，應該(gai)使用電(dian)(dian)(dian)(dian)子負載的(de)定電(dian)(dian)(dian)(dian)流(liu)模式，而電(dian)(dian)(dian)(dian)池(chi)應在要(yao)求的(de)電(dian)(dian)(dian)(dian)壓范圍內(nei)，在規格(ge)時(shi)間(jian)提供測(ce)試(shi)的(de)電(dian)(dian)(dian)(dian)流(liu)，使用計(ji)算機(ji)(ji)或打印機(ji)(ji)來(lai)監視電(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)壓及電(dian)(dian)(dian)(dian)流(liu)。

　　定功率(lv)模式亦(yi)可(ke)用來(lai)測試電(dian)池的放(fang)電(dian)特性，當電(dian)子(zi)(zi)負載(zai)工作于定功率(lv)模式時(shi)，電(dian)子(zi)(zi)負載(zai)會(hui)從(cong)電(dian)池吸取所設定功率(lv)值。此時(shi)電(dian)子(zi)(zi)負載(zai)的電(dian)流會(hui)隨著(zhu)負載(zai)電(dian)壓的降低而自(zi)動增加保(bao)持功率(lv)恒定，反之亦(yi)然。

　　三、電池充電測試

　　一般(ban)含(han)恒(heng)(heng)壓和恒(heng)(heng)流(liu)輸(shu)出的直(zhi)(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)源可(ke)用來對(dui)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，或使用沒有(you)穩壓限流(liu)的直(zhi)(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)源(例如簡單的整(zheng)流(liu)與(yu)電(dian)(dian)(dian)(dian)(dian)(dian)容濾波(bo)電(dian)(dian)(dian)(dian)(dian)(dian)路)與(yu)直(zhi)(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)載(zai)串聯做為電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)源對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，此時充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)大小由電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)載(zai)定電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)模式下的設定電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)值(zhi)決定。

　　對(dui)于電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)器與電(dian)(dian)(dian)池的測(ce)試測(ce)量就介(jie)紹(shao)到這里，希(xi)望大家都能更加(jia)深入了解電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)器!
