充電電池放電后需要充電器來充電(dian)(dian)(dian)(dian)，一(yi)個良好的(de)(de)充電(dian)(dian)(dian)(dian)器應(ying)該能(neng)夠提(ti)(ti)供(gong)恒定電(dian)(dian)(dian)(dian)流(liu)來充電(dian)(dian)(dian)(dian)，并(bing)且(qie)在電(dian)(dian)(dian)(dian)池足時能(neng)夠自動停止充電(dian)(dian)(dian)(dian)這樣(yang)才能(neng)使電(dian)(dian)(dian)(dian)池的(de)(de)壽(shou)命最長。海洋(yang)儀器推(tui)出的(de)(de)博計電(dian)(dian)(dian)(dian)子負(fu)載(zai)(zai)提(ti)(ti)供(gong)了非(fei)常(chang)良好的(de)(de)電(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)器測(ce)試解決方案，可以用來仿真鎳(nie)鎘、鎳(nie)氫等電(dian)(dian)(dian)(dian)池的(de)(de)電(dian)(dian)(dian)(dian)壓及負(fu)載(zai)(zai)形式。

     在充電過程中，當電池端電壓開始下降時(―△V負電壓斜率)，電池充電器應停止充(chong)電(dian)(dian)(dian)，對電(dian)(dian)(dian)池(chi)(chi)的過充(chong)會造(zao)成電(dian)(dian)(dian)池(chi)(chi)永久性損壞。在測(ce)(ce)試電(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)器時(shi)，可以使用真(zhen)實(shi)(shi)的充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)測(ce)(ce)試，然(ran)而這種方法需(xu)要(yao)非常冗長(chang)時(shi)間，并不切實(shi)(shi)際或不符(fu)合經濟效益。當(dang)使用電(dian)(dian)(dian)子(zi)負載時(shi)，可以設定(ding)(ding)為(wei)定(ding)(ding)電(dian)(dian)(dian)壓(ya)負載模式(shi)，并且(qie)設定(ding)(ding)所需(xu)的端電(dian)(dian)(dian)壓(ya)，此時(shi)電(dian)(dian)(dian)子(zi)負載將吸取足夠電(dian)(dian)(dian)流控(kong)制(zhi)電(dian)(dian)(dian)壓(ya)穩定(ding)(ding)到設定(ding)(ding)值。例如：測(ce)(ce)試1.2V的充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)設定(ding)(ding)端電(dian)(dian)(dian)壓(ya)從1V、1.2V、1.4V、1.5V來測(ce)(ce)試電(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)器的電(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)足)來測(ce)(ce)試充(chong)電(dian)(dian)(dian)器是否會停止充(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)壓(ya)和充電(dian)電(dian)流，五組記憶設定可設定高達五個不(bu)同的(de)端電(dian)壓(ya)，以(yi)達到方便及(ji)重復性(xing)的(de)測(ce)試需(xu)求。注意：實際充電(dian)電(dian)池輸出電(dian)壓(ya)可能(neng)不(bu)是1.2V，而是1.2V的(de)倍數。
