低溫(wen)情(qing)況(kuang)下，電(dian)(dian)(dian)(dian)池(chi)(chi)溫(wen)度(du)低于(yu)0℃時，不帶(dai)加(jia)(jia)熱(re)功(gong)(gong)能(neng)(neng)的電(dian)(dian)(dian)(dian)池(chi)(chi)組(zu)，放(fang)電(dian)(dian)(dian)(dian)完電(dian)(dian)(dian)(dian)池(chi)(chi)溫(wen)度(du)高于(yu)0℃請馬上充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，或(huo)者將電(dian)(dian)(dian)(dian)池(chi)(chi)放(fang)入暖庫，待電(dian)(dian)(dian)(dian)池(chi)(chi)溫(wen)度(du)升高到5℃以(yi)上再充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)。如(ru)果(guo)是(shi)帶(dai)加(jia)(jia)熱(re)功(gong)(gong)能(neng)(neng)的電(dian)(dian)(dian)(dian)池(chi)(chi)組(zu)，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時請留意充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)機(ji)是(shi)否(fou)工作。充(chong)(chong)(chong)(chong)滿電(dian)(dian)(dian)(dian)之后請盡快斷開充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)機(ji)，切勿充(chong)(chong)(chong)(chong)滿電(dian)(dian)(dian)(dian)后長時間不管不顧(gu)。

1、給電池包加熱

如(ru)果不考慮電(dian)(dian)池包加熱，基本不可能做到不損(sun)耗容(rong)量(liang)，畢竟你的溫(wen)度(du)時-25度(du)環(huan)境(jing)； 這樣(yang)的低溫(wen)環(huan)境(jing)就是簡(jian)單的常溫(wen)充電(dian)(dian)，低溫(wen)放(fang)電(dian)(dian)都會對電(dian)(dian)池容(rong)量(liang)有損(sun)耗，更(geng)何況你還要(yao)低溫(wen)充電(dian)(dian)。 建議措施：給電(dian)(dian)池包加熱。

三元電(dian)(dian)(dian)池低溫(wen)充電(dian)(dian)(dian)，目(mu)前我(wo)們(men)公(gong)司的單體電(dian)(dian)(dian)池（30Ah）只能保證可(ke)以在0℃充放電(dian)(dian)(dian)而不(bu)造成(cheng)電(dian)(dian)(dian)池損耗。如果模塊(kuai)要(yao)-25℃下充放電(dian)(dian)(dian)，建議(yi)做外部加熱。 另(ling)外，跟電(dian)(dian)(dian)壓沒有多大關系，只要(yao)充電(dian)(dian)(dian)有鋰嵌入到(dao)負極，就有可(ke)能產生析鋰，

2、減少充電速度

-20℃時，如果使用C/30的速度給三元鋰電池充(chong)電(dian)(dian)，最(zui)終的(de)容(rong)(rong)量只有標稱的(de)77%，如果減少充(chong)電(dian)(dian)速度(du)(du)到(dao)C/100，最(zui)終容(rong)(rong)量可達100%，但要連續4天才能充(chong)滿一顆電(dian)(dian)池。故此可以考(kao)慮(lv)先慢(man)充(chong)以提高電(dian)(dian)池溫度(du)(du)，再改換成快充(chong)，部分車(che)企的(de)BMS也有該功能，比(bi)如說以C/5的(de)速度(du)(du)充(chong)至20%，再全速充(chong)電(dian)(dian)。

3、提高電池溫度

盡可(ke)能在房間里充電(dian)，比(bi)如(ru)說地下(xia)停車(che)(che)場，部分熱管理系統做得好的車(che)(che)企，絕對(dui)是可(ke)以極大地提高電(dian)車(che)(che)寒冷的冬(dong)季電(dian)動(dong)車(che)(che)續航的。
