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)(shi)指(zhi)電(dian)池(chi)(chi)中實際(ji)儲存電(dian)能(neng)的(de)(de)容(rong)量(liang)(liang)。電(dian)芯(xin)是(shi)(shi)電(dian)池(chi)(chi)的(de)(de)核(he)心器(qi)件，電(dian)芯(xin)容(rong)額是(shi)(shi)指(zhi)電(dian)芯(xin)所(suo)擁有的(de)(de)真(zhen)正(zheng)的(de)(de)儲存電(dian)能(neng)的(de)(de)容(rong)量(liang)(liang)。由于電(dian)池(chi)(chi)本身也(ye)會存在一定的(de)(de)損耗，所(suo)以電(dian)池(chi)(chi)輸(shu)出(chu)的(de)(de)容(rong)量(liang)(liang)常(chang)常(chang)是(shi)(shi)小于電(dian)芯(xin)容(rong)額的(de)(de)。這也(ye)是(shi)(shi)為(wei)什么在市場上比較靠譜的(de)(de)產品，會在包裝上標注上電(dian)芯(xin)容(rong)量(liang)(liang)，而不是(shi)(shi)單(dan)純的(de)(de)額定容(rong)量(liang)(liang)。

2、額定容額

額定(ding)容(rong)(rong)額是指廠(chang)家為電(dian)池(chi)(chi)(chi)規定(ding)的(de)(de)標準容(rong)(rong)量(liang)(liang)，也就是電(dian)池(chi)(chi)(chi)的(de)(de)正常使用容(rong)(rong)量(liang)(liang)。在低功率(lv)使用下，電(dian)池(chi)(chi)(chi)可承受最長的(de)(de)時間。例(li)如，一塊(kuai)標有(you)(you)1500mAh的(de)(de)AA電(dian)池(chi)(chi)(chi)，在正常情況下，是可以(yi)提供1500毫安時的(de)(de)電(dian)能，但在實(shi)際的(de)(de)使用過程中，電(dian)池(chi)(chi)(chi)提供的(de)(de)電(dian)能有(you)(you)可能會比額定(ding)容(rong)(rong)量(liang)(liang)少一些，這個因(yin)素(su)涉及到電(dian)池(chi)(chi)(chi)內阻、放電(dian)倍率(lv)等復雜(za)因(yin)素(su)。

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(e)較高，而在冬(dong)天氣溫(wen)較低(di)時(shi)活(huo)躍度不夠，容額(e)就會變(bian)低(di)。

額(e)(e)(e)定容(rong)(rong)(rong)額(e)(e)(e)是(shi)(shi)(shi)(shi)電(dian)(dian)池(chi)(chi)(chi)上標(biao)(biao)注的(de)容(rong)(rong)(rong)量，比如我們(men)使用(yong)(yong)(yong)的(de)手機所用(yong)(yong)(yong)的(de)鋰電(dian)(dian)池(chi)(chi)(chi)的(de)容(rong)(rong)(rong)量通常(chang)會(hui)有一(yi)個額(e)(e)(e)定值(zhi)。在實(shi)際使用(yong)(yong)(yong)中，電(dian)(dian)池(chi)(chi)(chi)的(de)實(shi)際容(rong)(rong)(rong)量是(shi)(shi)(shi)(shi)要比額(e)(e)(e)定容(rong)(rong)(rong)額(e)(e)(e)低，原(yuan)因就(jiu)是(shi)(shi)(shi)(shi)使用(yong)(yong)(yong)過程(cheng)中很難達(da)到最理想的(de)狀態(tai)，會(hui)導致(zhi)實(shi)際容(rong)(rong)(rong)量往(wang)往(wang)達(da)不(bu)到額(e)(e)(e)定容(rong)(rong)(rong)額(e)(e)(e)。另外，電(dian)(dian)池(chi)(chi)(chi)額(e)(e)(e)定容(rong)(rong)(rong)額(e)(e)(e)是(shi)(shi)(shi)(shi)指(zhi)標(biao)(biao)準(zhun)所標(biao)(biao)稱(cheng)電(dian)(dian)池(chi)(chi)(chi)的(de)容(rong)(rong)(rong)量值(zhi)大小，而(er)電(dian)(dian)芯(xin)容(rong)(rong)(rong)額(e)(e)(e)是(shi)(shi)(shi)(shi)指(zhi)電(dian)(dian)池(chi)(chi)(chi)在一(yi)定電(dian)(dian)流值(zhi)放電(dian)(dian)時的(de)實(shi)際容(rong)(rong)(rong)量大小。
