快充對電池真的有損害嗎？

快(kuai)充和(he)慢(man)充的概念：快(kuai)充和(he)慢(man)充是相對的概念，一般快(kuai)充為大功率(lv)直流(liu)充電(dian)(dian)(dian)，半小(xiao)時可以充滿電(dian)(dian)(dian)池的80%容量，慢(man)充指交流(liu)充電(dian)(dian)(dian)，充電(dian)(dian)(dian)過程需6-8小(xiao)時，

快充

一般的快充(chong)(chong)樁(zhuang)輸出(chu)直流(liu)電(dian)(dian)(dian)壓(ya)為380V，電(dian)(dian)(dian)流(liu)可(ke)達50A，輸出(chu)功率可(ke)達19KW以(yi)上。不(bu)過，威力保護(hu)電(dian)(dian)(dian)池，再電(dian)(dian)(dian)池容量達到80%以(yi)后，充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)會慢慢下降到10A左右。30分鐘(zhong)可(ke)充(chong)(chong)滿80%的電(dian)(dian)(dian)量，比(bi)較(jiao)適合臨時補(bu)電(dian)(dian)(dian)或自駕出(chu)游時充(chong)(chong)電(dian)(dian)(dian)。

慢充

一般的慢充樁輸出電壓為220V，電流25A左右，輸出功率一般為72KW，充滿一輛續航400Km的電動汽車至少需要8個小時，比較適合夜間或上班時間充電。

快充(chong)優缺點：短(duan)時(shi)間內對電池組進行快速補電，充(chong)電速度快；充(chong)電設備安(an)裝要求和成本(ben)較高(gao)，電流電壓較高(gao)，短(duan)時(shi)間內對電池沖擊較大，長期(qi)快速充(chong)電影響電池壽(shou)命。

慢(man)充優缺點(dian)：電(dian)(dian)流小，充(chong)(chong)電(dian)(dian)時間長，充(chong)(chong)電(dian)(dian)器和安裝成本較低(di)(di)；可充(chong)(chong)分利用電(dian)(dian)力低(di)(di)谷時段(duan)進(jin)行(xing)充(chong)(chong)電(dian)(dian)，降低(di)(di)充(chong)(chong)電(dian)(dian)成本；可對電(dian)(dian)池深(shen)度(du)充(chong)(chong)電(dian)(dian)，提升電(dian)(dian)池充(chong)(chong)放電(dian)(dian)效率(lv)，延長電(dian)(dian)池壽命。

結論：電(dian)(dian)池(chi)(chi)(chi)的(de)快速(su)充(chong)(chong)電(dian)(dian)是(shi)以(yi)犧牲電(dian)(dian)池(chi)(chi)(chi)的(de)循環壽命為代價，因為電(dian)(dian)池(chi)(chi)(chi)是(shi)通(tong)過電(dian)(dian)化學反(fan)應而產生(sheng)電(dian)(dian)能的(de)裝置，充(chong)(chong)電(dian)(dian)時發生(sheng)逆化學反(fan)應，而快速(su)充(chong)(chong)電(dian)(dian)將在瞬間向電(dian)(dian)池(chi)(chi)(chi)內輸入大3電(dian)(dian)流，經(jing)常使(shi)用快速(su)充(chong)(chong)電(dian)(dian)模式會降(jiang)低電(dian)(dian)池(chi)(chi)(chi)的(de)還原能力，減少電(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)放電(dian)(dian)的(de)循環次(ci)數(shu)，而慢充(chong)(chong)就可以(yi)很好(hao)的(de)避免這些問題。

如何(he)正確的保(bao)護(hu)愛車電池？

1、要保持電(dian)池的足電(dian)狀態，建議每天都充電(dian)，這樣(yang)使(shi)電(dian)池處于淺循環狀態，更利于電(dian)池使(shi)用壽命(ming)的延長。

2、在使(shi)用過程中，應(ying)根據實際情況把握充(chong)(chong)電時間和充(chong)(chong)電頻次，過度充(chong)(chong)電、過度放電不足都會縮短電池壽(shou)命(ming)。

3、盡可(ke)能的(de)用交流慢充充電，經常利(li)用直(zhi)流快充給電池組(zu)補電，會(hui)對電池壽(shou)命有一定的(de)影響，建(jian)議養成(cheng)“慢”的(de)使(shi)用習慣。

4、用(yong)車(che)過程中(zhong)，起(qi)步、上坡等操作時要盡(jin)量避免猛加速(su)，形(xing)成瞬間大電流放電，從(cong)而(er)損害電池的(de)物(wu)理性能，尤其(qi)是車(che)輛“滿載”的(de)情況下。

5、車輛閑(xian)置不用(yong)(yong)時，電(dian)(dian)池存(cun)儲一般采(cai)用(yong)(yong)半電(dian)(dian) 存(cun)儲。可以再30%-60%之間，鋰電(dian)(dian)池長時間不用(yong)(yong)的情況下電(dian)(dian)量會緩慢的衰減（內部鋰離子會回流），車輛廠(chang)時間停(ting)用(yong)(yong)后再次使用(yong)(yong)前，最好(hao)對車輛進行一次充(chong)電(dian)(dian)，均衡電(dian)(dian)量。

6、行駛過(guo)程中，盡量避(bi)免走(zou)坑洼路面，以免造(zao)成車輛托(tuo)底電池組保護外殼破損。
