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)(e)是指(zhi)電(dian)(dian)(dian)(dian)池(chi)(chi)中實際儲存電(dian)(dian)(dian)(dian)能的(de)容(rong)(rong)量。電(dian)(dian)(dian)(dian)芯(xin)(xin)是電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)核(he)心器件，電(dian)(dian)(dian)(dian)芯(xin)(xin)容(rong)(rong)額(e)(e)是指(zhi)電(dian)(dian)(dian)(dian)芯(xin)(xin)所(suo)擁有的(de)真(zhen)正的(de)儲存電(dian)(dian)(dian)(dian)能的(de)容(rong)(rong)量。由于(yu)(yu)電(dian)(dian)(dian)(dian)池(chi)(chi)本身(shen)也(ye)會(hui)存在一(yi)定的(de)損耗，所(suo)以電(dian)(dian)(dian)(dian)池(chi)(chi)輸出的(de)容(rong)(rong)量常常是小于(yu)(yu)電(dian)(dian)(dian)(dian)芯(xin)(xin)容(rong)(rong)額(e)(e)的(de)。這也(ye)是為什么在市場上(shang)比較靠譜的(de)產品，會(hui)在包裝上(shang)標注上(shang)電(dian)(dian)(dian)(dian)芯(xin)(xin)容(rong)(rong)量，而不是單純的(de)額(e)(e)定容(rong)(rong)量。

2、額定容額

額(e)定容額(e)是指廠家為電(dian)(dian)池(chi)(chi)規定的(de)(de)標(biao)準容量(liang)，也就是電(dian)(dian)池(chi)(chi)的(de)(de)正(zheng)常使用(yong)容量(liang)。在(zai)低(di)功率使用(yong)下，電(dian)(dian)池(chi)(chi)可承受最長(chang)的(de)(de)時間。例如(ru)，一塊標(biao)有1500mAh的(de)(de)AA電(dian)(dian)池(chi)(chi)，在(zai)正(zheng)常情況下，是可以(yi)提(ti)(ti)供(gong)1500毫安(an)時的(de)(de)電(dian)(dian)能(neng)，但在(zai)實際的(de)(de)使用(yong)過程(cheng)中(zhong)，電(dian)(dian)池(chi)(chi)提(ti)(ti)供(gong)的(de)(de)電(dian)(dian)能(neng)有可能(neng)會比額(e)定容量(liang)少一些(xie)，這個因素(su)涉(she)及到電(dian)(dian)池(chi)(chi)內阻、放電(dian)(dian)倍(bei)率等復(fu)雜(za)因素(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(rong)額較(jiao)高，而(er)在冬(dong)天(tian)氣溫較(jiao)低(di)時活躍度不夠，容(rong)額就會變低(di)。

額(e)(e)定(ding)容(rong)(rong)(rong)額(e)(e)是電(dian)(dian)池(chi)上標注的(de)(de)容(rong)(rong)(rong)量(liang)(liang)，比如我(wo)們使(shi)用(yong)的(de)(de)手機所用(yong)的(de)(de)鋰電(dian)(dian)池(chi)的(de)(de)容(rong)(rong)(rong)量(liang)(liang)通常會有(you)一個額(e)(e)定(ding)值(zhi)(zhi)。在實際使(shi)用(yong)中，電(dian)(dian)池(chi)的(de)(de)實際容(rong)(rong)(rong)量(liang)(liang)是要(yao)比額(e)(e)定(ding)容(rong)(rong)(rong)額(e)(e)低(di)，原因就是使(shi)用(yong)過程(cheng)中很(hen)難達到最(zui)理想的(de)(de)狀態(tai)，會導致實際容(rong)(rong)(rong)量(liang)(liang)往往達不到額(e)(e)定(ding)容(rong)(rong)(rong)額(e)(e)。另外，電(dian)(dian)池(chi)額(e)(e)定(ding)容(rong)(rong)(rong)額(e)(e)是指標準所標稱電(dian)(dian)池(chi)的(de)(de)容(rong)(rong)(rong)量(liang)(liang)值(zhi)(zhi)大小，而電(dian)(dian)芯容(rong)(rong)(rong)額(e)(e)是指電(dian)(dian)池(chi)在一定(ding)電(dian)(dian)流值(zhi)(zhi)放電(dian)(dian)時的(de)(de)實際容(rong)(rong)(rong)量(liang)(liang)大小。
