充電電池放電后需要充電器來充(chong)(chong)電(dian)(dian)，一個良(liang)好(hao)的(de)充(chong)(chong)電(dian)(dian)器(qi)應該能(neng)夠(gou)提供(gong)恒定電(dian)(dian)流來充(chong)(chong)電(dian)(dian)，并且在電(dian)(dian)池足時能(neng)夠(gou)自(zi)動停止充(chong)(chong)電(dian)(dian)這樣才能(neng)使電(dian)(dian)池的(de)壽命最(zui)長(chang)。海洋(yang)儀器(qi)推出的(de)博計電(dian)(dian)子負(fu)載提供(gong)了非常良(liang)好(hao)的(de)電(dian)(dian)池充(chong)(chong)電(dian)(dian)器(qi)測(ce)試解(jie)決方案，可以用(yong)來仿真鎳鎘、鎳氫等電(dian)(dian)池的(de)電(dian)(dian)壓及負(fu)載形(xing)式。

     在充電過程中，當電池端電壓開始下降時(―△V負電壓斜率)，電池充電器應停(ting)止充(chong)(chong)電(dian)(dian)(dian)，對電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)過充(chong)(chong)會造成電(dian)(dian)(dian)池(chi)(chi)永(yong)久(jiu)性損壞。在測(ce)(ce)試(shi)電(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)器時，可(ke)以使用真實的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)測(ce)(ce)試(shi)，然(ran)而這(zhe)種(zhong)方法需(xu)要非(fei)常冗長時間(jian)，并不切(qie)實際或(huo)不符合(he)經(jing)濟(ji)效益。當使用電(dian)(dian)(dian)子負載時，可(ke)以設定(ding)(ding)為定(ding)(ding)電(dian)(dian)(dian)壓負載模式，并且(qie)設定(ding)(ding)所需(xu)的(de)(de)(de)端電(dian)(dian)(dian)壓，此(ci)時電(dian)(dian)(dian)子負載將吸取足夠電(dian)(dian)(dian)流控制電(dian)(dian)(dian)壓穩(wen)定(ding)(ding)到設定(ding)(ding)值。例如：測(ce)(ce)試(shi)1.2V的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)設定(ding)(ding)端電(dian)(dian)(dian)壓從1V、1.2V、1.4V、1.5V來(lai)測(ce)(ce)試(shi)電(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)器的(de)(de)(de)電(dian)(dian)(dian)流調整率，然(ran)后設定(ding)(ding) 1.48V(－△V模擬電(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)足)來(lai)測(ce)(ce)試(shi)充(chong)(chong)電(dian)(dian)(dian)器是否會停(ting)止充(chong)(chong)電(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)端電(dian)(dian)壓(ya)(ya)和充電(dian)(dian)電(dian)(dian)流(liu)，五(wu)組記憶設(she)定可設(she)定高(gao)達(da)五(wu)個不(bu)同(tong)的(de)端電(dian)(dian)壓(ya)(ya)，以(yi)達(da)到方便及重復性的(de)測試(shi)需求。注意(yi)：實際充電(dian)(dian)電(dian)(dian)池輸出電(dian)(dian)壓(ya)(ya)可能不(bu)是1.2V，而是1.2V的(de)倍數(shu)。
