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

　　充電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)放電(dian)(dian)(dian)后需(xu)要充電(dian)(dian)(dian)器來充電(dian)(dian)(dian)，一個良好的充電(dian)(dian)(dian)器應該能(neng)夠提供(gong)恒(heng)定電(dian)(dian)(dian)流來充電(dian)(dian)(dian)，并且在電(dian)(dian)(dian)池(chi)(chi)足時(shi)能(neng)夠自動停止充電(dian)(dian)(dian)這樣(yang)才能(neng)使電(dian)(dian)(dian)池(chi)(chi)的壽命(ming)最(zui)長(chang)。

　　在充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)過程中，當(dang)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)端(duan)電(dian)(dian)(dian)(dian)壓(ya)開始下(xia)降時(shi)(—△V負電(dian)(dian)(dian)(dian)壓(ya)斜率(lv)(lv))，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器應停止充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，對(dui)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的過充(chong)(chong)(chong)(chong)會(hui)造成電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)永久性損壞。在測試(shi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器時(shi)，可以使(shi)用(yong)真實的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)測試(shi)，然而這(zhe)種(zhong)方法(fa)需(xu)(xu)要非常(chang)冗長時(shi)間，并(bing)不(bu)切實際(ji)或不(bu)符合(he)經(jing)濟效益。當(dang)使(shi)用(yong)電(dian)(dian)(dian)(dian)子(zi)(zi)負載時(shi)，可以設定(ding)為定(ding)電(dian)(dian)(dian)(dian)壓(ya)負載模式，并(bing)且設定(ding)所需(xu)(xu)的端(duan)電(dian)(dian)(dian)(dian)壓(ya)，此(ci)時(shi)電(dian)(dian)(dian)(dian)子(zi)(zi)負載將吸取足夠(gou)電(dian)(dian)(dian)(dian)流控制電(dian)(dian)(dian)(dian)壓(ya)穩(wen)定(ding)到(dao)設定(ding)值(zhi)。例(li)如：測試(shi)1.2V的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)設定(ding)端(duan)電(dian)(dian)(dian)(dian)壓(ya)從(cong)1V、1.2V、1.4V、1.5V來(lai)測試(shi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器的電(dian)(dian)(dian)(dian)流調(diao)整(zheng)率(lv)(lv)，然后設定(ding) 1.48V(-△V模擬電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)足)來(lai)測試(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器是(shi)否(fou)會(hui)停止充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)。

　　二、電池放電測試

　　任何電池(chi)均可視為一個電壓(ya)源，其(qi)儲存容量單位為mAH或AH，例如(ru)12V 6AH 的電池(chi)容量表(biao)示它在12V和1A輸出時可工作六個小時。

　　測試電(dian)(dian)池的(de)(de)放電(dian)(dian)特性(xing)時，應該使用電(dian)(dian)子負載(zai)的(de)(de)定電(dian)(dian)流模式，而電(dian)(dian)池應在要求(qiu)的(de)(de)電(dian)(dian)壓范(fan)圍內，在規格時間(jian)提(ti)供測試的(de)(de)電(dian)(dian)流，使用計算機或打(da)印機來(lai)監視(shi)電(dian)(dian)池的(de)(de)電(dian)(dian)壓及電(dian)(dian)流。

　　定(ding)(ding)功(gong)率(lv)模式亦可用來(lai)測試電(dian)(dian)(dian)(dian)池(chi)的放(fang)電(dian)(dian)(dian)(dian)特性，當電(dian)(dian)(dian)(dian)子負(fu)(fu)(fu)載(zai)(zai)工作于定(ding)(ding)功(gong)率(lv)模式時(shi)，電(dian)(dian)(dian)(dian)子負(fu)(fu)(fu)載(zai)(zai)會從電(dian)(dian)(dian)(dian)池(chi)吸(xi)取所設定(ding)(ding)功(gong)率(lv)值(zhi)。此時(shi)電(dian)(dian)(dian)(dian)子負(fu)(fu)(fu)載(zai)(zai)的電(dian)(dian)(dian)(dian)流會隨著負(fu)(fu)(fu)載(zai)(zai)電(dian)(dian)(dian)(dian)壓的降低而自動增加(jia)保持功(gong)率(lv)恒定(ding)(ding)，反之亦然(ran)。

　　三、電池充電測試

　　一般含恒(heng)壓和恒(heng)流(liu)(liu)輸出(chu)的直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)源可用(yong)來(lai)對充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，或使用(yong)沒有穩壓限流(liu)(liu)的直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)源(例(li)如簡單的整流(liu)(liu)與電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)濾(lv)波電(dian)(dian)(dian)(dian)(dian)(dian)路)與直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)載(zai)(zai)串聯做為電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)源對電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，此(ci)時充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大(da)小由電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)載(zai)(zai)定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)模(mo)式下的設定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)值決定(ding)。

　　對(dui)于電(dian)(dian)池(chi)充電(dian)(dian)器與電(dian)(dian)池(chi)的測試測量就介紹到這(zhe)里，希望大家都能(neng)更加深入了(le)解電(dian)(dian)池(chi)充電(dian)(dian)器!
