一、電芯容額和額定容額分別是什么意思

1、電芯容額

電芯容(rong)(rong)額(e)是指電(dian)(dian)池中實際(ji)儲存電(dian)(dian)能(neng)(neng)的(de)(de)(de)(de)容(rong)(rong)量(liang)(liang)。電(dian)(dian)芯(xin)是電(dian)(dian)池的(de)(de)(de)(de)核心器(qi)件，電(dian)(dian)芯(xin)容(rong)(rong)額(e)是指電(dian)(dian)芯(xin)所擁有(you)的(de)(de)(de)(de)真正的(de)(de)(de)(de)儲存電(dian)(dian)能(neng)(neng)的(de)(de)(de)(de)容(rong)(rong)量(liang)(liang)。由于電(dian)(dian)池本(ben)身也會存在(zai)一定的(de)(de)(de)(de)損耗，所以電(dian)(dian)池輸出的(de)(de)(de)(de)容(rong)(rong)量(liang)(liang)常常是小于電(dian)(dian)芯(xin)容(rong)(rong)額(e)的(de)(de)(de)(de)。這也是為什么在(zai)市場上(shang)(shang)比(bi)較靠譜的(de)(de)(de)(de)產品，會在(zai)包裝上(shang)(shang)標注上(shang)(shang)電(dian)(dian)芯(xin)容(rong)(rong)量(liang)(liang)，而不是單(dan)純(chun)的(de)(de)(de)(de)額(e)定容(rong)(rong)量(liang)(liang)。

2、額定容額

額定容額是(shi)指廠家(jia)為電池(chi)(chi)規定的(de)(de)標準容量，也就是(shi)電池(chi)(chi)的(de)(de)正(zheng)(zheng)常使用(yong)容量。在(zai)低功(gong)率(lv)使用(yong)下，電池(chi)(chi)可承受最長(chang)的(de)(de)時間。例如，一塊標有(you)1500mAh的(de)(de)AA電池(chi)(chi)，在(zai)正(zheng)(zheng)常情況下，是(shi)可以(yi)提(ti)供1500毫安(an)時的(de)(de)電能(neng)，但在(zai)實(shi)際的(de)(de)使用(yong)過程中(zhong)，電池(chi)(chi)提(ti)供的(de)(de)電能(neng)有(you)可能(neng)會比(bi)額定容量少一些，這個因素涉及到電池(chi)(chi)內阻、放電倍率(lv)等復雜因素。

二、電芯容額和額定容額的區別

電芯容額往往小于額定容額。電池容額，又叫實際容額，一般指的是電池在放電的狀態下，它所具備的當前的實際容量。實際容量往往是會不斷變化的，比如在夏天氣溫較高時它的分子比較活躍，此時的電芯容額較高，而在冬天(tian)氣溫較低時活(huo)躍度不夠，容額就會(hui)變(bian)低。

額定(ding)(ding)容(rong)(rong)額是(shi)(shi)電(dian)(dian)池(chi)(chi)上標(biao)注(zhu)的(de)容(rong)(rong)量(liang)，比(bi)(bi)如(ru)我們使(shi)用(yong)的(de)手機所用(yong)的(de)鋰電(dian)(dian)池(chi)(chi)的(de)容(rong)(rong)量(liang)通(tong)常(chang)會有一(yi)個額定(ding)(ding)值。在實際使(shi)用(yong)中，電(dian)(dian)池(chi)(chi)的(de)實際容(rong)(rong)量(liang)是(shi)(shi)要(yao)比(bi)(bi)額定(ding)(ding)容(rong)(rong)額低，原因(yin)就是(shi)(shi)使(shi)用(yong)過程中很難達(da)到最(zui)理想(xiang)的(de)狀態，會導致實際容(rong)(rong)量(liang)往(wang)(wang)往(wang)(wang)達(da)不(bu)到額定(ding)(ding)容(rong)(rong)額。另(ling)外，電(dian)(dian)池(chi)(chi)額定(ding)(ding)容(rong)(rong)額是(shi)(shi)指(zhi)標(biao)準所標(biao)稱電(dian)(dian)池(chi)(chi)的(de)容(rong)(rong)量(liang)值大(da)小，而電(dian)(dian)芯容(rong)(rong)額是(shi)(shi)指(zhi)電(dian)(dian)池(chi)(chi)在一(yi)定(ding)(ding)電(dian)(dian)流值放電(dian)(dian)時的(de)實際容(rong)(rong)量(liang)大(da)小。
