電源適配器正(zheng)式投入市(shi)場之(zhi)前一定會(hui)會(hui)進行各種測試，例如(ru)放電測試與充電測試，今天我們(men)一起來看一下電源適配器與電池(chi)的測試測量!

　一、電(dian)池充電(dian)測(ce)試

　　充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池放電(dian)(dian)(dian)(dian)后需要(yao)電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配器(qi)來充電(dian)(dian)(dian)(dian)，一(yi)個良好的(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配器(qi)應該能夠(gou)提供恒定(ding)電(dian)(dian)(dian)(dian)流來充電(dian)(dian)(dian)(dian)，并(bing)且在電(dian)(dian)(dian)(dian)池足時能夠(gou)自動(dong)停止充電(dian)(dian)(dian)(dian)這樣才能使電(dian)(dian)(dian)(dian)池的(de)壽命最長。

　　在充(chong)(chong)(chong)電(dian)(dian)(dian)過程(cheng)中(zhong)，當電(dian)(dian)(dian)池(chi)(chi)端(duan)電(dian)(dian)(dian)壓開(kai)始下降時(shi)(—△V負(fu)電(dian)(dian)(dian)壓斜率(lv))，電(dian)(dian)(dian)源適(shi)配器應停止充(chong)(chong)(chong)電(dian)(dian)(dian)，對電(dian)(dian)(dian)池(chi)(chi)的(de)過充(chong)(chong)(chong)會(hui)造成電(dian)(dian)(dian)池(chi)(chi)永(yong)久性損壞。在測(ce)試(shi)(shi)電(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)器時(shi)，可(ke)以(yi)使用真實的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)測(ce)試(shi)(shi)，然而這種方法需(xu)要非常冗長時(shi)間，并不(bu)切(qie)實際(ji)或(huo)不(bu)符合經濟效(xiao)益。當使用電(dian)(dian)(dian)子負(fu)載時(shi)，可(ke)以(yi)設(she)定為(wei)定電(dian)(dian)(dian)壓負(fu)載模式(shi)，并且設(she)定所需(xu)的(de)端(duan)電(dian)(dian)(dian)壓，此時(shi)電(dian)(dian)(dian)子負(fu)載將(jiang)吸取足(zu)夠電(dian)(dian)(dian)流(liu)控制電(dian)(dian)(dian)壓穩定到設(she)定值(zhi)。例如(ru)：測(ce)試(shi)(shi)1.2V的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)設(she)定端(duan)電(dian)(dian)(dian)壓從1V、1.2V、1.4V、1.5V來測(ce)試(shi)(shi)電(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)器的(de)電(dian)(dian)(dian)流(liu)調整率(lv)，然后設(she)定 1.48V(-△V模擬電(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)足(zu))來測(ce)試(shi)(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)器是否會(hui)停止充(chong)(chong)(chong)電(dian)(dian)(dian)。

　　二、電池放電測試(shi)

　　任何電池均可視為一(yi)個電壓(ya)源，其儲存容(rong)量(liang)單位為mAH或(huo)AH，例如12V 6AH 的電池容(rong)量(liang)表示它在12V和1A輸出時可工作六個小時。

　　測(ce)試(shi)電(dian)池(chi)的放電(dian)特性(xing)時(shi)，應該使用電(dian)子負載的定(ding)電(dian)流模式，而電(dian)池(chi)應在要求(qiu)的電(dian)壓(ya)范圍內，在規格時(shi)間提供測(ce)試(shi)的電(dian)流，使用計算機或打印(yin)機來(lai)監視電(dian)池(chi)的電(dian)壓(ya)及(ji)電(dian)流。

　　定功(gong)(gong)率(lv)模式亦可用來測試電(dian)(dian)池的(de)(de)放(fang)電(dian)(dian)特性(xing)，當電(dian)(dian)子負(fu)(fu)(fu)載(zai)工作于(yu)定功(gong)(gong)率(lv)模式時(shi)，電(dian)(dian)子負(fu)(fu)(fu)載(zai)會從(cong)電(dian)(dian)池吸(xi)取(qu)所設定功(gong)(gong)率(lv)值。此時(shi)電(dian)(dian)子負(fu)(fu)(fu)載(zai)的(de)(de)電(dian)(dian)流會隨著負(fu)(fu)(fu)載(zai)電(dian)(dian)壓的(de)(de)降(jiang)低(di)而(er)自(zi)動(dong)增加保持功(gong)(gong)率(lv)恒定，反之亦然。

　　三、電(dian)池充電(dian)測(ce)試

　　一般含恒(heng)壓和恒(heng)流輸出的直流電(dian)(dian)(dian)(dian)源可用來(lai)對(dui)充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)，或使用沒有穩(wen)壓限流的直流電(dian)(dian)(dian)(dian)源(例如簡單的整流與電(dian)(dian)(dian)(dian)容濾(lv)波電(dian)(dian)(dian)(dian)路)與直流電(dian)(dian)(dian)(dian)子負載(zai)串(chuan)聯做為電(dian)(dian)(dian)(dian)流源對(dui)電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)，此(ci)時充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流大小(xiao)由電(dian)(dian)(dian)(dian)子負載(zai)定(ding)電(dian)(dian)(dian)(dian)流模(mo)式下的設定(ding)電(dian)(dian)(dian)(dian)流值決定(ding)。
