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)電(dian)池放電(dian)后需要充(chong)(chong)電(dian)器來充(chong)(chong)電(dian)，一個良(liang)好(hao)的充(chong)(chong)電(dian)器應該能(neng)(neng)夠提供恒定電(dian)流來充(chong)(chong)電(dian)，并且(qie)在電(dian)池足時能(neng)(neng)夠自動停止(zhi)充(chong)(chong)電(dian)這(zhe)樣才能(neng)(neng)使電(dian)池的壽(shou)命最(zui)長。

　　在充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)過程中(zhong)，當電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)端電(dian)(dian)(dian)壓(ya)(ya)開始下降時(—△V負電(dian)(dian)(dian)壓(ya)(ya)斜(xie)率)，電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)應停(ting)止充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，對電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)過充(chong)(chong)(chong)(chong)會造(zao)成(cheng)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)永(yong)久(jiu)性損壞。在測(ce)試(shi)(shi)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)時，可以使用(yong)真實的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)測(ce)試(shi)(shi)，然而這種方法需要(yao)非常冗(rong)長時間，并(bing)不(bu)切實際或不(bu)符合經(jing)濟(ji)效(xiao)益(yi)。當使用(yong)電(dian)(dian)(dian)子負載時，可以設定(ding)(ding)為(wei)定(ding)(ding)電(dian)(dian)(dian)壓(ya)(ya)負載模式，并(bing)且設定(ding)(ding)所需的(de)端電(dian)(dian)(dian)壓(ya)(ya)，此時電(dian)(dian)(dian)子負載將(jiang)吸(xi)取足夠電(dian)(dian)(dian)流(liu)控(kong)制電(dian)(dian)(dian)壓(ya)(ya)穩定(ding)(ding)到設定(ding)(ding)值。例如：測(ce)試(shi)(shi)1.2V的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)設定(ding)(ding)端電(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)池(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)的(de)電(dian)(dian)(dian)流(liu)調整率，然后(hou)設定(ding)(ding) 1.48V(-△V模擬電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)足)來(lai)測(ce)試(shi)(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)是否會停(ting)止充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)。

　　二、電池放電測試

　　任(ren)何電(dian)池均可視為一個(ge)電(dian)壓源，其儲(chu)存容量單位為mAH或AH，例如(ru)12V 6AH 的電(dian)池容量表示它在(zai)12V和(he)1A輸出(chu)時可工作六個(ge)小時。

　　測試(shi)(shi)電(dian)(dian)池的(de)放電(dian)(dian)特性時，應該使用電(dian)(dian)子負載(zai)的(de)定電(dian)(dian)流(liu)(liu)模式(shi)，而電(dian)(dian)池應在(zai)要求(qiu)的(de)電(dian)(dian)壓范(fan)圍內(nei)，在(zai)規格時間提(ti)供(gong)測試(shi)(shi)的(de)電(dian)(dian)流(liu)(liu)，使用計算機或打印機來監(jian)視電(dian)(dian)池的(de)電(dian)(dian)壓及電(dian)(dian)流(liu)(liu)。

　　定功(gong)(gong)(gong)率模(mo)式亦可用(yong)來(lai)測試電池(chi)的(de)放(fang)電特性，當電子(zi)負載(zai)工作于(yu)定功(gong)(gong)(gong)率模(mo)式時，電子(zi)負載(zai)會(hui)從(cong)電池(chi)吸(xi)取所設定功(gong)(gong)(gong)率值。此時電子(zi)負載(zai)的(de)電流(liu)會(hui)隨(sui)著(zhu)負載(zai)電壓(ya)的(de)降低(di)而自動增加保持功(gong)(gong)(gong)率恒定，反之亦然。

　　三、電池充電測試

　　一般含恒(heng)壓和恒(heng)流(liu)(liu)(liu)輸出的(de)(de)直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)源可用(yong)來對(dui)充電(dian)(dian)電(dian)(dian)池(chi)充電(dian)(dian)，或使用(yong)沒有穩壓限流(liu)(liu)(liu)的(de)(de)直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)源(例如簡單的(de)(de)整流(liu)(liu)(liu)與電(dian)(dian)容濾(lv)波電(dian)(dian)路)與直(zhi)(zhi)流(liu)(liu)(liu)電(dian)(dian)子負載串聯做為(wei)電(dian)(dian)流(liu)(liu)(liu)源對(dui)電(dian)(dian)池(chi)充電(dian)(dian)，此時充電(dian)(dian)電(dian)(dian)流(liu)(liu)(liu)大小由電(dian)(dian)子負載定電(dian)(dian)流(liu)(liu)(liu)模式下的(de)(de)設定電(dian)(dian)流(liu)(liu)(liu)值決定。

　　對于(yu)電(dian)池(chi)(chi)充電(dian)器(qi)與電(dian)池(chi)(chi)的(de)測試測量就介紹到這里，希望大家(jia)都能(neng)更(geng)加深入了解電(dian)池(chi)(chi)充電(dian)器(qi)!
