一、電芯soc是什么意思
電芯SOC指的是(shi)電(dian)(dian)(dian)(dian)池(chi)(chi)荷電(dian)(dian)(dian)(dian)狀(zhuang)(zhuang)態(tai),它(ta)反映了(le)電(dian)(dian)(dian)(dian)池(chi)(chi)的剩(sheng)余容(rong)量相對于(yu)完(wan)(wan)全充(chong)電(dian)(dian)(dian)(dian)狀(zhuang)(zhuang)態(tai)的比(bi)例(li)。具體(ti)來說,SOC是(shi)通(tong)過(guo)(guo)比(bi)較電(dian)(dian)(dian)(dian)池(chi)(chi)的實際容(rong)量與理論最(zui)大容(rong)量的比(bi)例(li)來定義的,這個比(bi)例(li)通(tong)常(chang)在0到1之間。當SOC等于(yu)0時,意味著電(dian)(dian)(dian)(dian)池(chi)(chi)已(yi)經完(wan)(wan)全放電(dian)(dian)(dian)(dian);而(er)當SOC等于(yu)1時,則表示電(dian)(dian)(dian)(dian)池(chi)(chi)已(yi)完(wan)(wan)全充(chong)滿。鋰離子電(dian)(dian)(dian)(dian)池(chi)(chi)要準(zhun)確(que)測(ce)量SOC并不是(shi)一件容(rong)易的事,因為它(ta)涉及到電(dian)(dian)(dian)(dian)池(chi)(chi)的內阻、開路(lu)電(dian)(dian)(dian)(dian)壓(ya)、溫度和電(dian)(dian)(dian)(dian)流等多種參數(shu),需要通(tong)過(guo)(guo)數(shu)學模型進(jin)行(xing)預測(ce)。123
需要(yao)注(zhu)意的是,SOC的概念與系統級(ji)芯片(SoC)不同。SoC是一種集成了處理器、內(nei)存和其他功(gong)能(neng)的完(wan)整芯片,它(ta)將多個獨立的功(gong)能(neng)集成在一個小型芯片上,以減小電子(zi)產(chan)品的尺寸并提(ti)高(gao)能(neng)效。
二、電芯soc低怎么辦
如果電(dian)芯(xin)的(de)SOC(電(dian)池(chi)的(de)剩余電(dian)量)太低(di),電(dian)池(chi)的(de)電(dian)壓可(ke)(ke)能會非(fei)常低(di),甚至(zhi)低(di)于啟動充電(dian)時所需的(de)最低(di)電(dian)壓。這種情況下,可(ke)(ke)以嘗試以下方法(fa)來解決問題:
1、將電池連接到具有大電流輸出(chu)能(neng)力的電源(yuan)中,例如汽車發動(dong)機,以充電電池。等待一段時間(jian)后,電芯SOC將會(hui)增加,然后再嘗試啟動(dong)充電。
2、如果電芯SOC非常低,可以使用一個專門的電芯充電(dian)(dian)器(qi)來給電(dian)(dian)池充電(dian)(dian)。這種充電(dian)(dian)器(qi)通常具(ju)有充電(dian)(dian)電(dian)(dian)流(liu)(liu)調節功(gong)能,可以在(zai)電(dian)(dian)芯SOC非常低時(shi)提供更高的充電(dian)(dian)電(dian)(dian)流(liu)(liu)。
3、如果電芯(xin)SOC非常(chang)低(di)且(qie)沒有外部(bu)充(chong)電設(she)備可(ke)用,可(ke)以通過(guo)使用一個較(jiao)小電流(liu)(liu)(liu)的恒流(liu)(liu)(liu)源來啟動充(chong)電。這可(ke)以避免因為電流(liu)(liu)(liu)過(guo)大(da)造成的損(sun)壞,但(dan)是(shi)充(chong)電速(su)度(du)可(ke)能相(xiang)對較(jiao)慢(man)。
