充電電池放電后需要充電器來充(chong)電(dian)(dian)(dian)(dian)，一個良好(hao)的(de)充(chong)電(dian)(dian)(dian)(dian)器應該(gai)能夠提供(gong)恒(heng)定電(dian)(dian)(dian)(dian)流來充(chong)電(dian)(dian)(dian)(dian)，并且在(zai)電(dian)(dian)(dian)(dian)池(chi)足時能夠自動停止充(chong)電(dian)(dian)(dian)(dian)這(zhe)樣才能使電(dian)(dian)(dian)(dian)池(chi)的(de)壽命最長。海洋儀器推出的(de)博計電(dian)(dian)(dian)(dian)子(zi)負載(zai)提供(gong)了非常良好(hao)的(de)電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)器測試解決(jue)方案，可以(yi)用來仿真鎳鎘、鎳氫等電(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)壓及(ji)負載(zai)形(xing)式(shi)。

     在充電過程中，當電池端電壓開始下降時(―△V負電壓斜率)，電池充電器應(ying)停(ting)止充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，對電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)過充(chong)(chong)(chong)(chong)會造成(cheng)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)永(yong)久性(xing)損壞。在測(ce)(ce)(ce)試電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)時(shi)，可(ke)以使用真實的(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)測(ce)(ce)(ce)試，然而這種方法需要(yao)非常(chang)冗長時(shi)間，并(bing)不切實際或(huo)不符合經濟效益。當使用電(dian)(dian)(dian)(dian)(dian)子負(fu)載時(shi)，可(ke)以設(she)定(ding)為定(ding)電(dian)(dian)(dian)(dian)(dian)壓負(fu)載模式，并(bing)且設(she)定(ding)所(suo)需的(de)(de)端電(dian)(dian)(dian)(dian)(dian)壓，此時(shi)電(dian)(dian)(dian)(dian)(dian)子負(fu)載將吸取足夠電(dian)(dian)(dian)(dian)(dian)流控(kong)制電(dian)(dian)(dian)(dian)(dian)壓穩定(ding)到設(she)定(ding)值。例如：測(ce)(ce)(ce)試1.2V的(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)設(she)定(ding)端電(dian)(dian)(dian)(dian)(dian)壓從1V、1.2V、1.4V、1.5V來(lai)測(ce)(ce)(ce)試電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)流調整率(lv)，然后設(she)定(ding) 1.48V(－△V模擬電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)足)來(lai)測(ce)(ce)(ce)試充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)是否會停(ting)止充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。

    當使用海洋儀器推出的博計3302機框與3310D系列模塊式電子負載時，面板上電壓/電流表可直接顯示電池充電器的(de)端(duan)電(dian)(dian)壓(ya)和(he)充電(dian)(dian)電(dian)(dian)流，五(wu)組記憶設(she)定可(ke)設(she)定高達五(wu)個不同的(de)端(duan)電(dian)(dian)壓(ya)，以達到方便(bian)及重復性的(de)測試(shi)需(xu)求。注意：實際充電(dian)(dian)電(dian)(dian)池輸出(chu)電(dian)(dian)壓(ya)可(ke)能不是(shi)1.2V，而是(shi)1.2V的(de)倍數。
