充電電池放電后需要充電器來(lai)充(chong)電(dian)(dian)，一(yi)個良好的(de)(de)(de)充(chong)電(dian)(dian)器應該(gai)能夠(gou)提(ti)供(gong)(gong)恒定(ding)電(dian)(dian)流來(lai)充(chong)電(dian)(dian)，并(bing)且在電(dian)(dian)池(chi)足時能夠(gou)自(zi)動停止充(chong)電(dian)(dian)這樣才能使電(dian)(dian)池(chi)的(de)(de)(de)壽命最長(chang)。海洋儀器推出(chu)的(de)(de)(de)博(bo)計電(dian)(dian)子負(fu)載(zai)提(ti)供(gong)(gong)了非(fei)常良好的(de)(de)(de)電(dian)(dian)池(chi)充(chong)電(dian)(dian)器測(ce)試(shi)解(jie)決方(fang)案，可以用來(lai)仿真鎳(nie)鎘(ge)、鎳(nie)氫(qing)等電(dian)(dian)池(chi)的(de)(de)(de)電(dian)(dian)壓(ya)及負(fu)載(zai)形(xing)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(ying)停(ting)止充(chong)(chong)電(dian)(dian)，對電(dian)(dian)池(chi)的(de)過充(chong)(chong)會(hui)造成電(dian)(dian)池(chi)永久性損壞。在測(ce)(ce)試電(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)器時(shi)，可以使(shi)用(yong)真(zhen)實的(de)充(chong)(chong)電(dian)(dian)電(dian)(dian)池(chi)測(ce)(ce)試，然(ran)而這種方法需要非常冗長(chang)時(shi)間(jian)，并(bing)不切(qie)實際或(huo)不符(fu)合經濟效益。當使(shi)用(yong)電(dian)(dian)子(zi)負(fu)載(zai)(zai)時(shi)，可以設(she)定(ding)(ding)(ding)為(wei)定(ding)(ding)(ding)電(dian)(dian)壓負(fu)載(zai)(zai)模(mo)式，并(bing)且(qie)設(she)定(ding)(ding)(ding)所需的(de)端電(dian)(dian)壓，此時(shi)電(dian)(dian)子(zi)負(fu)載(zai)(zai)將吸取足(zu)夠電(dian)(dian)流控制電(dian)(dian)壓穩定(ding)(ding)(ding)到設(she)定(ding)(ding)(ding)值。例(li)如(ru)：測(ce)(ce)試1.2V的(de)充(chong)(chong)電(dian)(dian)電(dian)(dian)池(chi)設(she)定(ding)(ding)(ding)端電(dian)(dian)壓從1V、1.2V、1.4V、1.5V來(lai)(lai)測(ce)(ce)試電(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)器的(de)電(dian)(dian)流調整率，然(ran)后(hou)設(she)定(ding)(ding)(ding) 1.48V(－△V模(mo)擬電(dian)(dian)池(chi)充(chong)(chong)足(zu))來(lai)(lai)測(ce)(ce)試充(chong)(chong)電(dian)(dian)器是否(fou)會(hui)停(ting)止充(chong)(chong)電(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(duan)電壓和充電電流(liu)，五組記憶設(she)定(ding)(ding)可(ke)設(she)定(ding)(ding)高達五個(ge)不同的(de)端(duan)電壓，以達到方(fang)便及重復性的(de)測試需(xu)求。注意：實際(ji)充電電池輸出電壓可(ke)能不是1.2V，而是1.2V的(de)倍數。
