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)電電池放電后需要充(chong)電器(qi)(qi)來充(chong)電，一(yi)個(ge)良(liang)好的充(chong)電器(qi)(qi)應該能(neng)夠提供恒定電流來充(chong)電，并且在電池足時能(neng)夠自動停(ting)止充(chong)電這樣(yang)才能(neng)使電池的壽命最(zui)長。

　　在充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程中(zhong)，當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)開始下降時(—△V負(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)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器應停(ting)止(zhi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)過充(chong)(chong)會造(zao)成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)永久(jiu)性(xing)損壞。在測(ce)(ce)試電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器時，可(ke)以(yi)(yi)使用真(zhen)實(shi)的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)測(ce)(ce)試，然而這種方法需(xu)要(yao)非(fei)常冗(rong)長時間，并(bing)不切實(shi)際或不符合經(jing)濟效益。當使用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子負(fu)(fu)載時，可(ke)以(yi)(yi)設(she)定(ding)(ding)(ding)為定(ding)(ding)(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)負(fu)(fu)載模式，并(bing)且設(she)定(ding)(ding)(ding)所需(xu)的(de)端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，此時電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子負(fu)(fu)載將吸取足(zu)夠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流控制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)穩定(ding)(ding)(ding)到設(she)定(ding)(ding)(ding)值(zhi)。例如：測(ce)(ce)試1.2V的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)設(she)定(ding)(ding)(ding)端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)從1V、1.2V、1.4V、1.5V來(lai)(lai)測(ce)(ce)試電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流調(diao)整率，然后設(she)定(ding)(ding)(ding) 1.48V(-△V模擬電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)足(zu))來(lai)(lai)測(ce)(ce)試充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器是否(fou)會停(ting)止(zhi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

　　二、電池放電測試

　　任(ren)何(he)電池(chi)均可視(shi)為一個(ge)電壓源(yuan)，其儲存容(rong)量(liang)單位為mAH或AH，例如12V 6AH 的(de)電池(chi)容(rong)量(liang)表示(shi)它在12V和(he)1A輸(shu)出時(shi)可工作六個(ge)小時(shi)。

　　測(ce)試電(dian)池的(de)放電(dian)特(te)性時(shi)，應(ying)該(gai)使(shi)用電(dian)子負載(zai)的(de)定(ding)電(dian)流(liu)模(mo)式(shi)，而電(dian)池應(ying)在要求(qiu)的(de)電(dian)壓范圍內，在規(gui)格時(shi)間(jian)提供測(ce)試的(de)電(dian)流(liu)，使(shi)用計算(suan)機或(huo)打印機來監視(shi)電(dian)池的(de)電(dian)壓及(ji)電(dian)流(liu)。

　　定功(gong)率模(mo)式亦可用(yong)來測試(shi)電池(chi)的放電特性，當電子(zi)負(fu)載(zai)工(gong)作于定功(gong)率模(mo)式時，電子(zi)負(fu)載(zai)會(hui)從電池(chi)吸取所設定功(gong)率值。此時電子(zi)負(fu)載(zai)的電流會(hui)隨(sui)著負(fu)載(zai)電壓(ya)的降低而自動增加保持(chi)功(gong)率恒定，反之亦然(ran)。

　　三、電池充電測試

　　一般(ban)含(han)恒(heng)壓和恒(heng)流(liu)輸出的(de)(de)直流(liu)電(dian)(dian)源可用(yong)來對(dui)充(chong)電(dian)(dian)電(dian)(dian)池(chi)充(chong)電(dian)(dian)，或使(shi)用(yong)沒(mei)有穩壓限流(liu)的(de)(de)直流(liu)電(dian)(dian)源(例(li)如簡(jian)單的(de)(de)整流(liu)與電(dian)(dian)容濾波電(dian)(dian)路)與直流(liu)電(dian)(dian)子(zi)負載(zai)串聯做(zuo)為電(dian)(dian)流(liu)源對(dui)電(dian)(dian)池(chi)充(chong)電(dian)(dian)，此時充(chong)電(dian)(dian)電(dian)(dian)流(liu)大小由電(dian)(dian)子(zi)負載(zai)定(ding)電(dian)(dian)流(liu)模(mo)式下的(de)(de)設定(ding)電(dian)(dian)流(liu)值決定(ding)。

　　對(dui)于電(dian)(dian)池充(chong)電(dian)(dian)器與電(dian)(dian)池的測試測量就介紹到這里(li)，希(xi)望大家都能更加深(shen)入了解電(dian)(dian)池充(chong)電(dian)(dian)器!
