一、電芯soc是什么意思

電芯SOC指的(de)(de)(de)是電(dian)池(chi)荷電(dian)狀態(tai)，它(ta)反映了電(dian)池(chi)的(de)(de)(de)剩余容(rong)量相(xiang)對于完(wan)全充電(dian)狀態(tai)的(de)(de)(de)比(bi)例(li)。具體(ti)來說，SOC是通過比(bi)較電(dian)池(chi)的(de)(de)(de)實(shi)際容(rong)量與(yu)理論最大容(rong)量的(de)(de)(de)比(bi)例(li)來定義的(de)(de)(de)，這個(ge)比(bi)例(li)通常在0到1之間。當SOC等(deng)于0時(shi)，意味著電(dian)池(chi)已(yi)經完(wan)全放電(dian)；而當SOC等(deng)于1時(shi)，則表(biao)示電(dian)池(chi)已(yi)完(wan)全充滿(man)。鋰離子電(dian)池(chi)要準確測(ce)量SOC并不是一件容(rong)易的(de)(de)(de)事，因為它(ta)涉及(ji)到電(dian)池(chi)的(de)(de)(de)內阻、開路電(dian)壓、溫度和電(dian)流等(deng)多(duo)種參數(shu)，需要通過數(shu)學模型進(jin)行預測(ce)。123

需要(yao)注意(yi)的是(shi)，SOC的概(gai)念與系統(tong)級芯片（SoC）不同。SoC是(shi)一(yi)種集成(cheng)(cheng)了(le)處(chu)理器、內存(cun)和其他功(gong)能的完整芯片，它將(jiang)多個(ge)獨(du)立(li)的功(gong)能集成(cheng)(cheng)在一(yi)個(ge)小型芯片上，以減小電子產品(pin)的尺(chi)寸并提高能效。

二、電芯soc低怎么辦

如果電(dian)(dian)芯的(de)SOC（電(dian)(dian)池的(de)剩余電(dian)(dian)量）太低，電(dian)(dian)池的(de)電(dian)(dian)壓(ya)可(ke)能(neng)會非常低，甚至低于啟(qi)動充電(dian)(dian)時所需的(de)最低電(dian)(dian)壓(ya)。這(zhe)種(zhong)情況下，可(ke)以嘗試(shi)以下方法來解(jie)決問題：

1、將電池連(lian)接(jie)到(dao)具有(you)大(da)電流輸(shu)出能力(li)的(de)電源中，例如(ru)汽車發動(dong)機，以(yi)充(chong)(chong)電電池。等待一段時間后(hou)，電芯SOC將會增加，然后(hou)再嘗(chang)試啟動(dong)充(chong)(chong)電。

2、如果電芯SOC非常低，可以使用一個專門的電芯充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)來給(gei)電(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)。這(zhe)種(zhong)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)通常具有充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流調節功能，可(ke)以在(zai)電(dian)(dian)(dian)(dian)芯SOC非常低時提供(gong)更(geng)高的充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流。

3、如果電(dian)(dian)芯SOC非常低且(qie)沒有外部充(chong)(chong)(chong)電(dian)(dian)設備(bei)可(ke)用，可(ke)以通過使用一個較(jiao)小電(dian)(dian)流(liu)的恒流(liu)源來啟動充(chong)(chong)(chong)電(dian)(dian)。這可(ke)以避免因為電(dian)(dian)流(liu)過大造成的損壞，但是充(chong)(chong)(chong)電(dian)(dian)速度(du)可(ke)能相對較(jiao)慢。
