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)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)放電(dian)(dian)(dian)(dian)(dian)后需要充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)來充(chong)電(dian)(dian)(dian)(dian)(dian)，一個良(liang)好的充(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)應該(gai)能夠(gou)提供(gong)恒定電(dian)(dian)(dian)(dian)(dian)流來充(chong)電(dian)(dian)(dian)(dian)(dian)，并(bing)且(qie)在(zai)電(dian)(dian)(dian)(dian)(dian)池(chi)足時能夠(gou)自動(dong)停止充(chong)電(dian)(dian)(dian)(dian)(dian)這樣才能使(shi)電(dian)(dian)(dian)(dian)(dian)池(chi)的壽命最長。

　　在(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)過程(cheng)中，當電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)壓開始下降時(shi)(shi)(—△V負(fu)電(dian)(dian)(dian)(dian)(dian)(dian)壓斜率)，電(dian)(dian)(dian)(dian)(dian)(dian)池(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)的(de)(de)過充(chong)(chong)會(hui)造成電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)永(yong)久性損壞(huai)。在(zai)測試(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)時(shi)(shi)，可以(yi)使(shi)用(yong)真實(shi)(shi)的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)測試(shi)(shi)，然而(er)這種方(fang)法需要非(fei)常(chang)冗(rong)長(chang)時(shi)(shi)間，并不切(qie)實(shi)(shi)際或(huo)不符合經(jing)濟效益。當使(shi)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)載時(shi)(shi)，可以(yi)設(she)(she)定為定電(dian)(dian)(dian)(dian)(dian)(dian)壓負(fu)載模式(shi)，并且(qie)設(she)(she)定所需的(de)(de)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)壓，此時(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)載將(jiang)吸(xi)取(qu)足夠(gou)電(dian)(dian)(dian)(dian)(dian)(dian)流控制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)壓穩定到設(she)(she)定值。例如：測試(shi)(shi)1.2V的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)設(she)(she)定端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)壓從1V、1.2V、1.4V、1.5V來測試(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流調(diao)整率，然后設(she)(she)定 1.48V(-△V模擬(ni)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)足)來測試(shi)(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)是(shi)否會(hui)停止充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。

　　二、電池放電測試

　　任何電池(chi)(chi)均可(ke)視為(wei)一(yi)個電壓源，其儲存容(rong)量(liang)單(dan)位為(wei)mAH或(huo)AH，例(li)如(ru)12V 6AH 的電池(chi)(chi)容(rong)量(liang)表示(shi)它在(zai)12V和1A輸出時可(ke)工(gong)作六個小時。

　　測試電(dian)(dian)(dian)(dian)池的放電(dian)(dian)(dian)(dian)特性時，應(ying)(ying)該使用電(dian)(dian)(dian)(dian)子負載的定電(dian)(dian)(dian)(dian)流(liu)(liu)模式，而(er)電(dian)(dian)(dian)(dian)池應(ying)(ying)在(zai)要求的電(dian)(dian)(dian)(dian)壓(ya)范圍內，在(zai)規格時間提(ti)供測試的電(dian)(dian)(dian)(dian)流(liu)(liu)，使用計算機或打(da)印(yin)機來(lai)監視電(dian)(dian)(dian)(dian)池的電(dian)(dian)(dian)(dian)壓(ya)及電(dian)(dian)(dian)(dian)流(liu)(liu)。

　　定(ding)(ding)功(gong)率模(mo)式亦可用來測(ce)試電(dian)(dian)(dian)(dian)池(chi)的(de)放電(dian)(dian)(dian)(dian)特(te)性，當電(dian)(dian)(dian)(dian)子(zi)負(fu)載工作(zuo)于(yu)定(ding)(ding)功(gong)率模(mo)式時，電(dian)(dian)(dian)(dian)子(zi)負(fu)載會從電(dian)(dian)(dian)(dian)池(chi)吸取所設定(ding)(ding)功(gong)率值。此時電(dian)(dian)(dian)(dian)子(zi)負(fu)載的(de)電(dian)(dian)(dian)(dian)流會隨(sui)著負(fu)載電(dian)(dian)(dian)(dian)壓的(de)降(jiang)低而自動增加保持功(gong)率恒定(ding)(ding)，反之亦然。

　　三、電池充電測試

　　一般(ban)含恒壓和恒流(liu)(liu)輸出的直(zhi)流(liu)(liu)電(dian)(dian)源(yuan)可用(yong)來對(dui)充(chong)電(dian)(dian)電(dian)(dian)池(chi)充(chong)電(dian)(dian)，或使用(yong)沒(mei)有穩壓限流(liu)(liu)的直(zhi)流(liu)(liu)電(dian)(dian)源(yuan)(例如簡單(dan)的整流(liu)(liu)與電(dian)(dian)容濾波電(dian)(dian)路)與直(zhi)流(liu)(liu)電(dian)(dian)子負(fu)載(zai)串聯做為電(dian)(dian)流(liu)(liu)源(yuan)對(dui)電(dian)(dian)池(chi)充(chong)電(dian)(dian)，此時(shi)充(chong)電(dian)(dian)電(dian)(dian)流(liu)(liu)大小(xiao)由電(dian)(dian)子負(fu)載(zai)定電(dian)(dian)流(liu)(liu)模式下的設定電(dian)(dian)流(liu)(liu)值決定。
