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)額是(shi)指電池(chi)中實際(ji)儲存電能(neng)(neng)的(de)(de)(de)容(rong)量(liang)。電芯(xin)(xin)是(shi)電池(chi)的(de)(de)(de)核心器件，電芯(xin)(xin)容(rong)額是(shi)指電芯(xin)(xin)所擁有(you)的(de)(de)(de)真正的(de)(de)(de)儲存電能(neng)(neng)的(de)(de)(de)容(rong)量(liang)。由于(yu)電池(chi)本身也會存在一定的(de)(de)(de)損耗，所以(yi)電池(chi)輸(shu)出的(de)(de)(de)容(rong)量(liang)常常是(shi)小于(yu)電芯(xin)(xin)容(rong)額的(de)(de)(de)。這也是(shi)為什么(me)在市場上比較靠譜的(de)(de)(de)產品，會在包裝上標注上電芯(xin)(xin)容(rong)量(liang)，而(er)不是(shi)單(dan)純的(de)(de)(de)額定容(rong)量(liang)。

2、額定容額

額(e)定容(rong)額(e)是(shi)指廠(chang)家為電(dian)(dian)池(chi)(chi)規定的(de)(de)標準容(rong)量(liang)(liang)，也就(jiu)是(shi)電(dian)(dian)池(chi)(chi)的(de)(de)正(zheng)常使用容(rong)量(liang)(liang)。在(zai)低(di)功(gong)率(lv)(lv)使用下，電(dian)(dian)池(chi)(chi)可承受最長的(de)(de)時(shi)(shi)間。例如，一塊標有1500mAh的(de)(de)AA電(dian)(dian)池(chi)(chi)，在(zai)正(zheng)常情況(kuang)下，是(shi)可以(yi)提(ti)供1500毫安時(shi)(shi)的(de)(de)電(dian)(dian)能(neng)，但在(zai)實際的(de)(de)使用過程中，電(dian)(dian)池(chi)(chi)提(ti)供的(de)(de)電(dian)(dian)能(neng)有可能(neng)會比額(e)定容(rong)量(liang)(liang)少一些，這個(ge)因(yin)素涉及到電(dian)(dian)池(chi)(chi)內阻、放電(dian)(dian)倍率(lv)(lv)等復雜因(yin)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(jiao)高，而在冬天氣溫(wen)較(jiao)低時活躍度(du)不夠，容額就會變低。

額(e)定容(rong)(rong)(rong)額(e)是(shi)(shi)電(dian)(dian)(dian)池上標(biao)注的(de)(de)容(rong)(rong)(rong)量(liang)，比(bi)如我們使(shi)用(yong)(yong)的(de)(de)手機所用(yong)(yong)的(de)(de)鋰電(dian)(dian)(dian)池的(de)(de)容(rong)(rong)(rong)量(liang)通(tong)常會(hui)有(you)一(yi)個額(e)定值(zhi)。在實(shi)際(ji)使(shi)用(yong)(yong)中，電(dian)(dian)(dian)池的(de)(de)實(shi)際(ji)容(rong)(rong)(rong)量(liang)是(shi)(shi)要比(bi)額(e)定容(rong)(rong)(rong)額(e)低，原(yuan)因就是(shi)(shi)使(shi)用(yong)(yong)過程中很(hen)難達到最理想的(de)(de)狀態，會(hui)導致(zhi)實(shi)際(ji)容(rong)(rong)(rong)量(liang)往往達不(bu)到額(e)定容(rong)(rong)(rong)額(e)。另(ling)外(wai)，電(dian)(dian)(dian)池額(e)定容(rong)(rong)(rong)額(e)是(shi)(shi)指標(biao)準所標(biao)稱電(dian)(dian)(dian)池的(de)(de)容(rong)(rong)(rong)量(liang)值(zhi)大小(xiao)，而電(dian)(dian)(dian)芯容(rong)(rong)(rong)額(e)是(shi)(shi)指電(dian)(dian)(dian)池在一(yi)定電(dian)(dian)(dian)流值(zhi)放電(dian)(dian)(dian)時的(de)(de)實(shi)際(ji)容(rong)(rong)(rong)量(liang)大小(xiao)。
