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)額是指電(dian)池(chi)中實際儲存電(dian)能(neng)的(de)容(rong)量(liang)。電(dian)芯(xin)(xin)是電(dian)池(chi)的(de)核(he)心(xin)器件，電(dian)芯(xin)(xin)容(rong)額是指電(dian)芯(xin)(xin)所擁有(you)的(de)真正的(de)儲存電(dian)能(neng)的(de)容(rong)量(liang)。由于電(dian)池(chi)本身也會存在(zai)一定的(de)損耗(hao)，所以(yi)電(dian)池(chi)輸出的(de)容(rong)量(liang)常(chang)常(chang)是小于電(dian)芯(xin)(xin)容(rong)額的(de)。這也是為什么在(zai)市場上比較(jiao)靠譜的(de)產(chan)品，會在(zai)包(bao)裝上標注上電(dian)芯(xin)(xin)容(rong)量(liang)，而不是單純的(de)額定容(rong)量(liang)。

2、額定容額

額(e)定(ding)容額(e)是指廠(chang)家為電(dian)(dian)池規定(ding)的(de)標準容量(liang)，也就是電(dian)(dian)池的(de)正常使(shi)用容量(liang)。在(zai)低(di)功率使(shi)用下，電(dian)(dian)池可(ke)承受最(zui)長(chang)的(de)時間。例如，一(yi)塊標有1500mAh的(de)AA電(dian)(dian)池，在(zai)正常情況下，是可(ke)以提供(gong)1500毫安時的(de)電(dian)(dian)能(neng)，但在(zai)實際(ji)的(de)使(shi)用過程中(zhong)，電(dian)(dian)池提供(gong)的(de)電(dian)(dian)能(neng)有可(ke)能(neng)會比額(e)定(ding)容量(liang)少一(yi)些(xie)，這個因(yin)素涉(she)及(ji)到電(dian)(dian)池內阻、放電(dian)(dian)倍(bei)率等復雜因(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(e)較高，而(er)在冬天氣溫較低時活躍度不夠，容額(e)就(jiu)會變(bian)低。

額(e)(e)(e)定(ding)容(rong)(rong)(rong)(rong)額(e)(e)(e)是(shi)電(dian)池(chi)(chi)上(shang)標注的(de)容(rong)(rong)(rong)(rong)量(liang)(liang)，比(bi)如我(wo)們使(shi)用(yong)(yong)(yong)的(de)手機(ji)所用(yong)(yong)(yong)的(de)鋰電(dian)池(chi)(chi)的(de)容(rong)(rong)(rong)(rong)量(liang)(liang)通常會(hui)有一個額(e)(e)(e)定(ding)值。在(zai)實際(ji)使(shi)用(yong)(yong)(yong)中(zhong)，電(dian)池(chi)(chi)的(de)實際(ji)容(rong)(rong)(rong)(rong)量(liang)(liang)是(shi)要比(bi)額(e)(e)(e)定(ding)容(rong)(rong)(rong)(rong)額(e)(e)(e)低，原(yuan)因就(jiu)是(shi)使(shi)用(yong)(yong)(yong)過程(cheng)中(zhong)很難(nan)達到最理(li)想的(de)狀(zhuang)態(tai)，會(hui)導致實際(ji)容(rong)(rong)(rong)(rong)量(liang)(liang)往往達不(bu)到額(e)(e)(e)定(ding)容(rong)(rong)(rong)(rong)額(e)(e)(e)。另外(wai)，電(dian)池(chi)(chi)額(e)(e)(e)定(ding)容(rong)(rong)(rong)(rong)額(e)(e)(e)是(shi)指標準所標稱電(dian)池(chi)(chi)的(de)容(rong)(rong)(rong)(rong)量(liang)(liang)值大小，而電(dian)芯容(rong)(rong)(rong)(rong)額(e)(e)(e)是(shi)指電(dian)池(chi)(chi)在(zai)一定(ding)電(dian)流值放電(dian)時的(de)實際(ji)容(rong)(rong)(rong)(rong)量(liang)(liang)大小。
