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)(e)是(shi)指(zhi)電(dian)(dian)池(chi)中實際儲存(cun)電(dian)(dian)能(neng)的(de)容(rong)(rong)量(liang)(liang)。電(dian)(dian)芯是(shi)電(dian)(dian)池(chi)的(de)核心器件，電(dian)(dian)芯容(rong)(rong)額(e)(e)(e)是(shi)指(zhi)電(dian)(dian)芯所(suo)擁有(you)的(de)真正的(de)儲存(cun)電(dian)(dian)能(neng)的(de)容(rong)(rong)量(liang)(liang)。由于電(dian)(dian)池(chi)本身也會存(cun)在(zai)一定的(de)損耗(hao)，所(suo)以電(dian)(dian)池(chi)輸出的(de)容(rong)(rong)量(liang)(liang)常常是(shi)小于電(dian)(dian)芯容(rong)(rong)額(e)(e)(e)的(de)。這也是(shi)為什么在(zai)市場上(shang)比較靠(kao)譜(pu)的(de)產(chan)品，會在(zai)包(bao)裝上(shang)標注上(shang)電(dian)(dian)芯容(rong)(rong)量(liang)(liang)，而不(bu)是(shi)單純的(de)額(e)(e)(e)定容(rong)(rong)量(liang)(liang)。

2、額定容額

額(e)定(ding)容額(e)是(shi)指廠家為(wei)電池(chi)規定(ding)的(de)(de)標(biao)準容量(liang)，也就(jiu)是(shi)電池(chi)的(de)(de)正常(chang)使(shi)用容量(liang)。在(zai)低功率使(shi)用下，電池(chi)可承(cheng)受最(zui)長的(de)(de)時(shi)間(jian)。例如，一(yi)(yi)塊標(biao)有(you)1500mAh的(de)(de)AA電池(chi)，在(zai)正常(chang)情況下，是(shi)可以(yi)提(ti)供1500毫安時(shi)的(de)(de)電能，但在(zai)實(shi)際的(de)(de)使(shi)用過程中，電池(chi)提(ti)供的(de)(de)電能有(you)可能會比(bi)額(e)定(ding)容量(liang)少一(yi)(yi)些，這(zhe)個因素涉及到電池(chi)內(nei)阻、放電倍(bei)率等復雜(za)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(jiao)高，而(er)在冬天氣溫較(jiao)低(di)時(shi)活躍度不(bu)夠，容額就會變低(di)。

額(e)(e)(e)定(ding)(ding)容(rong)(rong)(rong)(rong)額(e)(e)(e)是電(dian)(dian)池(chi)上標(biao)注(zhu)的(de)(de)(de)容(rong)(rong)(rong)(rong)量(liang)(liang)，比(bi)如我們使(shi)用(yong)的(de)(de)(de)手(shou)機所用(yong)的(de)(de)(de)鋰電(dian)(dian)池(chi)的(de)(de)(de)容(rong)(rong)(rong)(rong)量(liang)(liang)通常會有一個額(e)(e)(e)定(ding)(ding)值。在實(shi)(shi)際(ji)使(shi)用(yong)中，電(dian)(dian)池(chi)的(de)(de)(de)實(shi)(shi)際(ji)容(rong)(rong)(rong)(rong)量(liang)(liang)是要比(bi)額(e)(e)(e)定(ding)(ding)容(rong)(rong)(rong)(rong)額(e)(e)(e)低，原(yuan)因就是使(shi)用(yong)過(guo)程(cheng)中很(hen)難(nan)達到(dao)最理(li)想的(de)(de)(de)狀態，會導致(zhi)實(shi)(shi)際(ji)容(rong)(rong)(rong)(rong)量(liang)(liang)往往達不到(dao)額(e)(e)(e)定(ding)(ding)容(rong)(rong)(rong)(rong)額(e)(e)(e)。另(ling)外，電(dian)(dian)池(chi)額(e)(e)(e)定(ding)(ding)容(rong)(rong)(rong)(rong)額(e)(e)(e)是指(zhi)標(biao)準所標(biao)稱電(dian)(dian)池(chi)的(de)(de)(de)容(rong)(rong)(rong)(rong)量(liang)(liang)值大小，而電(dian)(dian)芯容(rong)(rong)(rong)(rong)額(e)(e)(e)是指(zhi)電(dian)(dian)池(chi)在一定(ding)(ding)電(dian)(dian)流值放電(dian)(dian)時(shi)的(de)(de)(de)實(shi)(shi)際(ji)容(rong)(rong)(rong)(rong)量(liang)(liang)大小。
