一、電芯soc是什么意思
電芯SOC指的(de)(de)(de)是(shi)電(dian)(dian)(dian)池(chi)(chi)(chi)荷電(dian)(dian)(dian)狀(zhuang)態,它(ta)反映了電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)剩余容量相對(dui)于(yu)完(wan)全充電(dian)(dian)(dian)狀(zhuang)態的(de)(de)(de)比(bi)(bi)例(li)。具體來(lai)說,SOC是(shi)通過比(bi)(bi)較電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)實際容量與理(li)論最大(da)容量的(de)(de)(de)比(bi)(bi)例(li)來(lai)定義的(de)(de)(de),這(zhe)個比(bi)(bi)例(li)通常在0到(dao)1之間。當(dang)SOC等(deng)于(yu)0時,意(yi)味著電(dian)(dian)(dian)池(chi)(chi)(chi)已(yi)經完(wan)全放電(dian)(dian)(dian);而(er)當(dang)SOC等(deng)于(yu)1時,則(ze)表(biao)示電(dian)(dian)(dian)池(chi)(chi)(chi)已(yi)完(wan)全充滿。鋰離(li)子電(dian)(dian)(dian)池(chi)(chi)(chi)要準確測量SOC并不是(shi)一件容易的(de)(de)(de)事,因為它(ta)涉及到(dao)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)內(nei)阻、開路(lu)電(dian)(dian)(dian)壓(ya)、溫度和(he)電(dian)(dian)(dian)流(liu)等(deng)多種參數,需要通過數學模型進行(xing)預測。123
需要注意的(de)是,SOC的(de)概念與系統(tong)級芯片(SoC)不同。SoC是一(yi)(yi)種集成(cheng)了處理器、內存和其他功能(neng)的(de)完整芯片,它將多個(ge)(ge)獨立(li)的(de)功能(neng)集成(cheng)在一(yi)(yi)個(ge)(ge)小(xiao)型芯片上,以減小(xiao)電子產(chan)品的(de)尺寸并提高(gao)能(neng)效。
二、電芯soc低怎么辦
如果電(dian)芯的(de)SOC(電(dian)池的(de)剩余電(dian)量)太低(di),電(dian)池的(de)電(dian)壓(ya)可(ke)能會非常低(di),甚至低(di)于啟(qi)動充電(dian)時所需的(de)最低(di)電(dian)壓(ya)。這種情況下(xia)(xia),可(ke)以嘗(chang)試(shi)以下(xia)(xia)方(fang)法來(lai)解決問(wen)題:
1、將(jiang)電(dian)(dian)池(chi)連(lian)接到具(ju)有大電(dian)(dian)流輸出能力的電(dian)(dian)源中,例如汽車(che)發動機,以充(chong)電(dian)(dian)電(dian)(dian)池(chi)。等待一段時間后(hou),電(dian)(dian)芯(xin)SOC將(jiang)會增加,然后(hou)再嘗試啟動充(chong)電(dian)(dian)。
2、如果電芯SOC非常低,可以使用一個專門的電芯充電(dian)器(qi)(qi)來給(gei)電(dian)池充電(dian)。這(zhe)種充電(dian)器(qi)(qi)通常(chang)(chang)具(ju)有充電(dian)電(dian)流(liu)調節(jie)功能,可以(yi)在電(dian)芯SOC非(fei)常(chang)(chang)低時(shi)提供更高的(de)充電(dian)電(dian)流(liu)。
3、如果電(dian)(dian)芯SOC非常低且沒(mei)有外部充(chong)電(dian)(dian)設備可(ke)用,可(ke)以通過使用一(yi)個較(jiao)小(xiao)電(dian)(dian)流(liu)(liu)的恒流(liu)(liu)源(yuan)來啟動充(chong)電(dian)(dian)。這可(ke)以避免因為電(dian)(dian)流(liu)(liu)過大(da)造成的損壞,但是充(chong)電(dian)(dian)速度可(ke)能相對較(jiao)慢。
