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)池放電(dian)(dian)后需要充(chong)電(dian)(dian)器來充(chong)電(dian)(dian)，一個良好的(de)充(chong)電(dian)(dian)器應(ying)該能夠提供恒定電(dian)(dian)流來充(chong)電(dian)(dian)，并且在(zai)電(dian)(dian)池足時能夠自動停止充(chong)電(dian)(dian)這(zhe)樣才(cai)能使電(dian)(dian)池的(de)壽命最長(chang)。

　　在(zai)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)(chi)(chi)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)開始下降時(shi)(shi)(—△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)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器應(ying)停(ting)止(zhi)(zhi)充電(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)(de)過充會造成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)永久性(xing)損(sun)壞。在(zai)測(ce)試(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器時(shi)(shi)，可以(yi)(yi)使(shi)用真實的(de)(de)充電(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)試(shi)(shi)，然而這種方法需要非常冗長時(shi)(shi)間，并不切實際(ji)或不符合經濟效益(yi)。當(dang)使(shi)用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)(fu)載(zai)時(shi)(shi)，可以(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(zai)模式，并且設(she)定(ding)(ding)(ding)所需的(de)(de)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，此(ci)時(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)(fu)載(zai)將吸取足夠(gou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)控(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)穩(wen)定(ding)(ding)(ding)到設(she)定(ding)(ding)(ding)值。例如：測(ce)試(shi)(shi)1.2V的(de)(de)充電(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(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)從1V、1.2V、1.4V、1.5V來(lai)測(ce)試(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)調整(zheng)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)充足)來(lai)測(ce)試(shi)(shi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器是(shi)否會停(ting)止(zhi)(zhi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

　　二、電池放電測試

　　任(ren)何電(dian)(dian)池(chi)均可視為一個電(dian)(dian)壓源，其(qi)儲存(cun)容量單位為mAH或(huo)AH，例如12V 6AH 的電(dian)(dian)池(chi)容量表示它在(zai)12V和1A輸(shu)出(chu)時(shi)可工作六個小時(shi)。

　　測試電(dian)(dian)(dian)池(chi)的(de)放電(dian)(dian)(dian)特性時(shi)，應該使用(yong)電(dian)(dian)(dian)子負(fu)載的(de)定電(dian)(dian)(dian)流(liu)模式，而電(dian)(dian)(dian)池(chi)應在(zai)要求的(de)電(dian)(dian)(dian)壓范圍內，在(zai)規(gui)格時(shi)間提供測試的(de)電(dian)(dian)(dian)流(liu)，使用(yong)計算機或打印機來監視電(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)壓及電(dian)(dian)(dian)流(liu)。

　　定功(gong)率(lv)模(mo)式亦可(ke)用(yong)來測(ce)試電(dian)池的放電(dian)特性，當電(dian)子(zi)負載工作于定功(gong)率(lv)模(mo)式時，電(dian)子(zi)負載會(hui)從電(dian)池吸取(qu)所設定功(gong)率(lv)值。此時電(dian)子(zi)負載的電(dian)流會(hui)隨著負載電(dian)壓的降低而自(zi)動增(zeng)加(jia)保(bao)持功(gong)率(lv)恒定，反(fan)之亦然。

　　三、電池充電測試

　　一般含(han)恒壓和恒流(liu)輸出的直(zhi)(zhi)流(liu)電(dian)(dian)源(yuan)可用(yong)來(lai)對(dui)充(chong)(chong)電(dian)(dian)電(dian)(dian)池充(chong)(chong)電(dian)(dian)，或使用(yong)沒有穩壓限流(liu)的直(zhi)(zhi)流(liu)電(dian)(dian)源(yuan)(例如簡單的整流(liu)與電(dian)(dian)容濾波電(dian)(dian)路)與直(zhi)(zhi)流(liu)電(dian)(dian)子負載(zai)串聯(lian)做為電(dian)(dian)流(liu)源(yuan)對(dui)電(dian)(dian)池充(chong)(chong)電(dian)(dian)，此時充(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)大小由電(dian)(dian)子負載(zai)定(ding)電(dian)(dian)流(liu)模式(shi)下的設定(ding)電(dian)(dian)流(liu)值(zhi)決定(ding)。

　　對于電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)器(qi)與電(dian)(dian)(dian)池的測試測量就介紹到這里，希望(wang)大家都能更加深入(ru)了解電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)器(qi)!
