充電電池放電后需要充電器來充電(dian)，一個良(liang)好的(de)充電(dian)器應(ying)該能(neng)夠(gou)提供恒定電(dian)流來充電(dian)，并且在電(dian)池(chi)(chi)(chi)足時(shi)能(neng)夠(gou)自動停止充電(dian)這樣(yang)才能(neng)使電(dian)池(chi)(chi)(chi)的(de)壽命(ming)最長。海(hai)洋儀(yi)器推(tui)出的(de)博計電(dian)子負(fu)載提供了非常良(liang)好的(de)電(dian)池(chi)(chi)(chi)充電(dian)器測試解決方案(an)，可以用來仿真鎳鎘、鎳氫等電(dian)池(chi)(chi)(chi)的(de)電(dian)壓及負(fu)載形式。

     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(zhi)(zhi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，對電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)過充(chong)(chong)(chong)會造成電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)永久性損壞。在(zai)測(ce)試電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)時(shi)，可以使(shi)用真實(shi)(shi)的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)測(ce)試，然而這種方法(fa)需要(yao)非常冗(rong)長時(shi)間，并(bing)不切實(shi)(shi)際或不符合經濟效益。當使(shi)用電(dian)(dian)(dian)(dian)(dian)子負(fu)(fu)載(zai)(zai)時(shi)，可以設(she)(she)定(ding)為定(ding)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)負(fu)(fu)載(zai)(zai)模(mo)式，并(bing)且(qie)設(she)(she)定(ding)所需的(de)端電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，此時(shi)電(dian)(dian)(dian)(dian)(dian)子負(fu)(fu)載(zai)(zai)將吸(xi)取足(zu)夠(gou)電(dian)(dian)(dian)(dian)(dian)流控(kong)制電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)穩定(ding)到(dao)設(she)(she)定(ding)值(zhi)。例如(ru)：測(ce)試1.2V的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)設(she)(she)定(ding)端電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)從1V、1.2V、1.4V、1.5V來測(ce)試電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)的(de)電(dian)(dian)(dian)(dian)(dian)流調(diao)整率，然后(hou)設(she)(she)定(ding) 1.48V(－△V模(mo)擬電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)足(zu))來測(ce)試充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)是否會停止(zhi)(zhi)充(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端(duan)電(dian)壓和充(chong)電(dian)電(dian)流，五組(zu)記憶設(she)(she)定(ding)可設(she)(she)定(ding)高達五個不(bu)(bu)同(tong)的端(duan)電(dian)壓，以達到方(fang)便(bian)及重復性的測試需求。注意(yi)：實際充(chong)電(dian)電(dian)池輸出(chu)電(dian)壓可能(neng)不(bu)(bu)是(shi)1.2V，而(er)是(shi)1.2V的倍(bei)數。
