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)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池放電(dian)(dian)(dian)后需(xu)要充(chong)(chong)電(dian)(dian)(dian)器來充(chong)(chong)電(dian)(dian)(dian)，一個良好的(de)充(chong)(chong)電(dian)(dian)(dian)器應該(gai)能夠(gou)提供恒定電(dian)(dian)(dian)流(liu)來充(chong)(chong)電(dian)(dian)(dian)，并(bing)且在電(dian)(dian)(dian)池足時能夠(gou)自動停止充(chong)(chong)電(dian)(dian)(dian)這樣才(cai)能使(shi)電(dian)(dian)(dian)池的(de)壽命(ming)最長。

　　在充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)過(guo)程(cheng)中(zhong)，當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)開(kai)始下降(jiang)時(—△V負(fu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)斜(xie)率(lv))，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)應停止充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，對電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)過(guo)充(chong)(chong)會造成電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)永久(jiu)性損壞。在測(ce)試(shi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)時，可以使(shi)用(yong)真實(shi)的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)測(ce)試(shi)，然而這種方法需要(yao)非常冗長時間，并(bing)不切實(shi)際或不符合經濟(ji)效益(yi)。當(dang)使(shi)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)子負(fu)載(zai)(zai)時，可以設(she)(she)定(ding)(ding)為定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)負(fu)載(zai)(zai)模(mo)式，并(bing)且設(she)(she)定(ding)(ding)所(suo)需的(de)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，此(ci)時電(dian)(dian)(dian)(dian)(dian)(dian)子負(fu)載(zai)(zai)將吸取足(zu)夠電(dian)(dian)(dian)(dian)(dian)(dian)流控制電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)穩定(ding)(ding)到(dao)設(she)(she)定(ding)(ding)值(zhi)。例如(ru)：測(ce)試(shi)1.2V的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)設(she)(she)定(ding)(ding)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)從1V、1.2V、1.4V、1.5V來(lai)測(ce)試(shi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)流調整率(lv)，然后設(she)(she)定(ding)(ding) 1.48V(-△V模(mo)擬電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)足(zu))來(lai)測(ce)試(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)是否會停止充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。

　　二、電池放電測試

　　任何電池均可(ke)視為一個電壓源，其儲存容量單位為mAH或AH，例如12V 6AH 的電池容量表示它在12V和1A輸出(chu)時(shi)可(ke)工作六個小時(shi)。

　　測試電(dian)(dian)(dian)池(chi)的(de)放電(dian)(dian)(dian)特性時，應該使用(yong)電(dian)(dian)(dian)子負載的(de)定(ding)電(dian)(dian)(dian)流模式，而電(dian)(dian)(dian)池(chi)應在要求的(de)電(dian)(dian)(dian)壓范圍內，在規格時間(jian)提(ti)供(gong)測試的(de)電(dian)(dian)(dian)流，使用(yong)計算機或(huo)打(da)印機來監視電(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)壓及電(dian)(dian)(dian)流。

　　定功率(lv)模(mo)式亦可用來測(ce)試電池的放電特(te)性，當電子負載工作于(yu)定功率(lv)模(mo)式時(shi)，電子負載會從電池吸取所(suo)設定功率(lv)值。此時(shi)電子負載的電流會隨著(zhu)負載電壓的降(jiang)低而(er)自動(dong)增加保(bao)持功率(lv)恒定，反之亦然。

　　三、電池充電測試

　　一般含(han)恒壓和恒流(liu)(liu)輸(shu)出的(de)(de)(de)直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)可用來(lai)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)，或使用沒(mei)有穩壓限流(liu)(liu)的(de)(de)(de)直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(例(li)如簡(jian)單(dan)的(de)(de)(de)整流(liu)(liu)與電(dian)(dian)(dian)(dian)(dian)容濾(lv)波電(dian)(dian)(dian)(dian)(dian)路)與直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)子(zi)負載串(chuan)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(zi)負載定電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)模式下的(de)(de)(de)設定電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)值決定。
