電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池內(nei)(nei)部阻(zu)(zu)抗，也(ye)稱為內(nei)(nei)阻(zu)(zu)，是一項影響(xiang)(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池性能(neng)的(de)重要指(zhi)標，每個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池都(dou)有(you)一個當(dang)(dang)量(liang)內(nei)(nei)阻(zu)(zu)，該電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)影響(xiang)(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池提(ti)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)的(de)能(neng)力，影響(xiang)(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池內(nei)(nei)阻(zu)(zu)的(de)因素有(you)：工作(zuo)時(shi)間、結(jie)構、狀況、溫度(du)(du)和充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀態。 當(dang)(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)，其(qi)內(nei)(nei)阻(zu)(zu)增大，當(dang)(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)達(da)到一定程度(du)(du)后(hou)，內(nei)(nei)阻(zu)(zu)的(de)變化量(liang)才(cai)很明顯(xian)，當(dang)(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池放(fang)完電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)后(hou)，其(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)比(bi)*充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀態時(shi)大2~5倍。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池溫度(du)(du)也(ye)影響(xiang)(xiang)內(nei)(nei)阻(zu)(zu)的(de)測(ce)量(liang)，但只(zhi)在冰點(dian)以下才(cai)比(bi)較(jiao)明顯(xian)，在32℉以下，溫度(du)(du)對內(nei)(nei)阻(zu)(zu)的(de)影響(xiang)(xiang)很大，在-20℉時(shi)的(de)
