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(dian)(dian)(dian)池(chi)(chi)中實際儲存電(dian)(dian)(dian)能(neng)的(de)(de)(de)容(rong)量(liang)(liang)。電(dian)(dian)(dian)芯(xin)是(shi)電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)核心器(qi)件，電(dian)(dian)(dian)芯(xin)容(rong)額是(shi)指電(dian)(dian)(dian)芯(xin)所擁有(you)的(de)(de)(de)真正的(de)(de)(de)儲存電(dian)(dian)(dian)能(neng)的(de)(de)(de)容(rong)量(liang)(liang)。由于電(dian)(dian)(dian)池(chi)(chi)本身(shen)也會(hui)存在(zai)(zai)一定(ding)的(de)(de)(de)損耗，所以電(dian)(dian)(dian)池(chi)(chi)輸出(chu)的(de)(de)(de)容(rong)量(liang)(liang)常(chang)常(chang)是(shi)小(xiao)于電(dian)(dian)(dian)芯(xin)容(rong)額的(de)(de)(de)。這也是(shi)為什么在(zai)(zai)市場上(shang)(shang)比較(jiao)靠(kao)譜的(de)(de)(de)產(chan)品(pin)，會(hui)在(zai)(zai)包裝(zhuang)上(shang)(shang)標注上(shang)(shang)電(dian)(dian)(dian)芯(xin)容(rong)量(liang)(liang)，而不(bu)是(shi)單純的(de)(de)(de)額定(ding)容(rong)量(liang)(liang)。

2、額定容額

額(e)定(ding)容(rong)(rong)額(e)是指廠家為電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)規定(ding)的標準容(rong)(rong)量，也就(jiu)是電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的正常(chang)使(shi)用(yong)容(rong)(rong)量。在(zai)低(di)功率(lv)使(shi)用(yong)下(xia)，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)可承受最長的時(shi)間。例(li)如(ru)，一塊標有1500mAh的AA電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，在(zai)正常(chang)情況下(xia)，是可以提(ti)供1500毫安時(shi)的電(dian)(dian)(dian)(dian)能(neng)(neng)，但在(zai)實(shi)際(ji)的使(shi)用(yong)過(guo)程中(zhong)，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)提(ti)供的電(dian)(dian)(dian)(dian)能(neng)(neng)有可能(neng)(neng)會(hui)比額(e)定(ding)容(rong)(rong)量少一些(xie)，這(zhe)個因(yin)素(su)(su)涉及(ji)到電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)內阻、放電(dian)(dian)(dian)(dian)倍率(lv)等復雜(za)因(yin)素(su)(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，此時的電芯容額較高，而在冬天氣溫較低時活(huo)躍(yue)度不夠，容額就會(hui)變(bian)低。

額(e)(e)(e)定(ding)(ding)容(rong)額(e)(e)(e)是(shi)電(dian)(dian)池(chi)(chi)上標注(zhu)的(de)(de)容(rong)量(liang)，比(bi)如我們使用的(de)(de)手機(ji)所(suo)用的(de)(de)鋰電(dian)(dian)池(chi)(chi)的(de)(de)容(rong)量(liang)通常會有一個額(e)(e)(e)定(ding)(ding)值。在(zai)實(shi)(shi)際使用中，電(dian)(dian)池(chi)(chi)的(de)(de)實(shi)(shi)際容(rong)量(liang)是(shi)要比(bi)額(e)(e)(e)定(ding)(ding)容(rong)額(e)(e)(e)低(di)，原因就是(shi)使用過程中很難達到最理想(xiang)的(de)(de)狀態，會導致實(shi)(shi)際容(rong)量(liang)往往達不到額(e)(e)(e)定(ding)(ding)容(rong)額(e)(e)(e)。另外，電(dian)(dian)池(chi)(chi)額(e)(e)(e)定(ding)(ding)容(rong)額(e)(e)(e)是(shi)指(zhi)標準所(suo)標稱電(dian)(dian)池(chi)(chi)的(de)(de)容(rong)量(liang)值大小(xiao)，而電(dian)(dian)芯容(rong)額(e)(e)(e)是(shi)指(zhi)電(dian)(dian)池(chi)(chi)在(zai)一定(ding)(ding)電(dian)(dian)流值放電(dian)(dian)時(shi)的(de)(de)實(shi)(shi)際容(rong)量(liang)大小(xiao)。
