充電電池放電后需要充電器來充(chong)(chong)電(dian)(dian)，一個(ge)良(liang)好的(de)充(chong)(chong)電(dian)(dian)器(qi)應該能夠提供(gong)恒定電(dian)(dian)流來充(chong)(chong)電(dian)(dian)，并且在電(dian)(dian)池足時能夠自動停止充(chong)(chong)電(dian)(dian)這樣才能使電(dian)(dian)池的(de)壽命(ming)最長。海洋(yang)儀器(qi)推出的(de)博計電(dian)(dian)子負載提供(gong)了非常良(liang)好的(de)電(dian)(dian)池充(chong)(chong)電(dian)(dian)器(qi)測試解決方案，可(ke)以用來仿真(zhen)鎳鎘、鎳氫等電(dian)(dian)池的(de)電(dian)(dian)壓(ya)及負載形式。

     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)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的過充(chong)(chong)(chong)(chong)會造成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)永久性損壞。在測(ce)(ce)(ce)試(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器時，可(ke)以使用真實的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)測(ce)(ce)(ce)試(shi)(shi)，然而這種方法需(xu)(xu)要非常冗長時間，并不(bu)切實際或不(bu)符(fu)合經濟效益。當(dang)使用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)載時，可(ke)以設定(ding)為定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)負(fu)載模式，并且設定(ding)所(suo)需(xu)(xu)的端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，此時電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)負(fu)載將吸(xi)取足夠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流控制電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)穩定(ding)到設定(ding)值。例(li)如：測(ce)(ce)(ce)試(shi)(shi)1.2V的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)設定(ding)端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)從(cong)1V、1.2V、1.4V、1.5V來(lai)測(ce)(ce)(ce)試(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流調整(zheng)率，然后設定(ding) 1.48V(－△V模擬電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)足)來(lai)測(ce)(ce)(ce)試(shi)(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器是否會停止充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(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(de)(de)端電(dian)壓和充電(dian)電(dian)流，五(wu)組記憶(yi)設定可(ke)設定高(gao)達(da)五(wu)個(ge)不同的(de)(de)端電(dian)壓，以達(da)到(dao)方便及重復性的(de)(de)測試需求。注意(yi)：實際充電(dian)電(dian)池輸出電(dian)壓可(ke)能不是1.2V，而是1.2V的(de)(de)倍(bei)數。
