充電電池放電后需要充電器來(lai)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，一個良好的充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器應該能夠(gou)提(ti)供恒定電(dian)(dian)(dian)(dian)流來(lai)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，并(bing)且在電(dian)(dian)(dian)(dian)池(chi)(chi)足時能夠(gou)自動停止充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)這樣才能使(shi)電(dian)(dian)(dian)(dian)池(chi)(chi)的壽(shou)命最長。海洋儀器推出的博計電(dian)(dian)(dian)(dian)子負(fu)載提(ti)供了非常良好的電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器測試解(jie)決方案，可以(yi)用來(lai)仿真(zhen)鎳(nie)鎘、鎳(nie)氫等電(dian)(dian)(dian)(dian)池(chi)(chi)的電(dian)(dian)(dian)(dian)壓(ya)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)，電池充電器應停止充(chong)(chong)(chong)(chong)(chong)電(dian)，對電(dian)池(chi)的(de)過(guo)充(chong)(chong)(chong)(chong)(chong)會造成電(dian)池(chi)永(yong)久性損壞。在測(ce)(ce)(ce)試(shi)電(dian)池(chi)充(chong)(chong)(chong)(chong)(chong)電(dian)器時(shi)，可(ke)以使(shi)用真實的(de)充(chong)(chong)(chong)(chong)(chong)電(dian)電(dian)池(chi)測(ce)(ce)(ce)試(shi)，然而這種方法需(xu)要非常冗長時(shi)間，并(bing)不切(qie)實際或不符(fu)合經濟(ji)效益(yi)。當使(shi)用電(dian)子負載(zai)時(shi)，可(ke)以設定(ding)(ding)(ding)為定(ding)(ding)(ding)電(dian)壓(ya)(ya)負載(zai)模(mo)式，并(bing)且設定(ding)(ding)(ding)所需(xu)的(de)端(duan)電(dian)壓(ya)(ya)，此時(shi)電(dian)子負載(zai)將(jiang)吸取(qu)足夠電(dian)流(liu)控制電(dian)壓(ya)(ya)穩定(ding)(ding)(ding)到設定(ding)(ding)(ding)值(zhi)。例如：測(ce)(ce)(ce)試(shi)1.2V的(de)充(chong)(chong)(chong)(chong)(chong)電(dian)電(dian)池(chi)設定(ding)(ding)(ding)端(duan)電(dian)壓(ya)(ya)從1V、1.2V、1.4V、1.5V來(lai)測(ce)(ce)(ce)試(shi)電(dian)池(chi)充(chong)(chong)(chong)(chong)(chong)電(dian)器的(de)電(dian)流(liu)調整率，然后(hou)設定(ding)(ding)(ding) 1.48V(－△V模(mo)擬電(dian)池(chi)充(chong)(chong)(chong)(chong)(chong)足)來(lai)測(ce)(ce)(ce)試(shi)充(chong)(chong)(chong)(chong)(chong)電(dian)器是否(fou)會停止充(chong)(chong)(chong)(chong)(chong)電(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)(de)端電(dian)(dian)壓和充電(dian)(dian)電(dian)(dian)流，五組記憶設定可設定高達(da)(da)五個不同(tong)的(de)(de)端電(dian)(dian)壓，以(yi)達(da)(da)到方(fang)便及重復性的(de)(de)測試(shi)需(xu)求。注意：實際充電(dian)(dian)電(dian)(dian)池輸(shu)出電(dian)(dian)壓可能不是1.2V，而是1.2V的(de)(de)倍(bei)數。
