充電電池放電后需要充電器來(lai)充(chong)電(dian)(dian)(dian)(dian)，一個良好的充(chong)電(dian)(dian)(dian)(dian)器(qi)應該能(neng)夠(gou)提供恒定電(dian)(dian)(dian)(dian)流來(lai)充(chong)電(dian)(dian)(dian)(dian)，并且在電(dian)(dian)(dian)(dian)池足時(shi)能(neng)夠(gou)自(zi)動(dong)停止充(chong)電(dian)(dian)(dian)(dian)這樣才能(neng)使電(dian)(dian)(dian)(dian)池的壽(shou)命最長。海洋儀器(qi)推出的博計電(dian)(dian)(dian)(dian)子負(fu)載提供了非常良好的電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)器(qi)測(ce)試解決方案，可以(yi)用來(lai)仿真鎳(nie)鎘、鎳(nie)氫(qing)等電(dian)(dian)(dian)(dian)池的電(dian)(dian)(dian)(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)，電池充電器應停止充(chong)(chong)電(dian)(dian)(dian)，對電(dian)(dian)(dian)池的過充(chong)(chong)會(hui)造成電(dian)(dian)(dian)池永久性損壞。在測(ce)試電(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)器(qi)時(shi)，可(ke)(ke)以使用真實的充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池測(ce)試，然而(er)這種方法需(xu)要非常冗長(chang)時(shi)間，并不(bu)切(qie)實際或不(bu)符合經濟效益。當使用電(dian)(dian)(dian)子負載時(shi)，可(ke)(ke)以設(she)定(ding)為定(ding)電(dian)(dian)(dian)壓(ya)負載模(mo)式，并且(qie)設(she)定(ding)所(suo)需(xu)的端電(dian)(dian)(dian)壓(ya)，此時(shi)電(dian)(dian)(dian)子負載將吸取足(zu)(zu)夠電(dian)(dian)(dian)流控制電(dian)(dian)(dian)壓(ya)穩定(ding)到設(she)定(ding)值(zhi)。例(li)如：測(ce)試1.2V的充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池設(she)定(ding)端電(dian)(dian)(dian)壓(ya)從1V、1.2V、1.4V、1.5V來測(ce)試電(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)器(qi)的電(dian)(dian)(dian)流調整率，然后設(she)定(ding) 1.48V(－△V模(mo)擬(ni)電(dian)(dian)(dian)池充(chong)(chong)足(zu)(zu))來測(ce)試充(chong)(chong)電(dian)(dian)(dian)器(qi)是(shi)否會(hui)停止充(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)(de)端電(dian)(dian)壓和充(chong)電(dian)(dian)電(dian)(dian)流，五組(zu)記憶設定可(ke)設定高(gao)達五個不同的(de)(de)端電(dian)(dian)壓，以達到方便及(ji)重復性的(de)(de)測(ce)試(shi)需求。注意：實際(ji)充(chong)電(dian)(dian)電(dian)(dian)池輸出電(dian)(dian)壓可(ke)能(neng)不是(shi)1.2V，而(er)是(shi)1.2V的(de)(de)倍數(shu)。
