快充對電池真的有損害嗎？

快(kuai)充(chong)(chong)(chong)和慢充(chong)(chong)(chong)的概(gai)念：快(kuai)充(chong)(chong)(chong)和慢充(chong)(chong)(chong)是相對的概(gai)念，一(yi)般快(kuai)充(chong)(chong)(chong)為大功(gong)率(lv)直(zhi)流充(chong)(chong)(chong)電，半小時(shi)可以充(chong)(chong)(chong)滿電池的80%容(rong)量，慢充(chong)(chong)(chong)指(zhi)交(jiao)流充(chong)(chong)(chong)電，充(chong)(chong)(chong)電過程需6-8小時(shi)，

快充

一般的快充樁輸出(chu)直流電壓為380V，電流可達50A，輸出(chu)功率(lv)可達19KW以上。不過，威力保護電池(chi)(chi)，再(zai)電池(chi)(chi)容量(liang)(liang)達到80%以后，充電電流會慢慢下降到10A左右。30分(fen)鐘可充滿80%的電量(liang)(liang)，比較適合臨(lin)時(shi)補電或自駕出(chu)游時(shi)充電。

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：短時(shi)間內對(dui)電池(chi)組進行快速(su)補(bu)電，充(chong)電速(su)度快；充(chong)電設備安裝要求和成本較(jiao)高，電流(liu)電壓較(jiao)高，短時(shi)間內對(dui)電池(chi)沖(chong)擊較(jiao)大(da)，長期(qi)快速(su)充(chong)電影響電池(chi)壽命。

慢(man)充優缺點(dian)：電(dian)(dian)(dian)流(liu)小，充(chong)(chong)電(dian)(dian)(dian)時間長，充(chong)(chong)電(dian)(dian)(dian)器(qi)和(he)安裝成本(ben)較低；可(ke)(ke)充(chong)(chong)分利用電(dian)(dian)(dian)力低谷時段(duan)進行充(chong)(chong)電(dian)(dian)(dian)，降低充(chong)(chong)電(dian)(dian)(dian)成本(ben)；可(ke)(ke)對電(dian)(dian)(dian)池(chi)深度充(chong)(chong)電(dian)(dian)(dian)，提升電(dian)(dian)(dian)池(chi)充(chong)(chong)放(fang)電(dian)(dian)(dian)效率，延(yan)長電(dian)(dian)(dian)池(chi)壽(shou)命。

結論：電(dian)池(chi)的快速(su)充電(dian)是以犧牲電(dian)池(chi)的循(xun)環(huan)(huan)壽命(ming)為代(dai)價，因為電(dian)池(chi)是通過電(dian)化學反應(ying)(ying)而產生電(dian)能(neng)的裝(zhuang)置，充電(dian)時發生逆(ni)化學反應(ying)(ying)，而快速(su)充電(dian)將在瞬(shun)間向電(dian)池(chi)內輸入(ru)大(da)3電(dian)流，經常使用快速(su)充電(dian)模(mo)式會降低電(dian)池(chi)的還原能(neng)力，減少(shao)電(dian)池(chi)充放(fang)電(dian)的循(xun)環(huan)(huan)次數，而慢充就(jiu)可以很(hen)好的避免這些問題(ti)。

如何正確的保護愛車電池？

1、要保持電池的足電狀(zhuang)態，建議(yi)每天(tian)都(dou)充電，這(zhe)樣使電池處于淺循(xun)環狀(zhuang)態，更(geng)利于電池使用壽命的延(yan)長。

2、在使用過(guo)程(cheng)中，應(ying)根據實際情況把握充電(dian)(dian)(dian)時間和充電(dian)(dian)(dian)頻次，過(guo)度(du)充電(dian)(dian)(dian)、過(guo)度(du)放電(dian)(dian)(dian)不足都(dou)會(hui)縮短電(dian)(dian)(dian)池壽命。

3、盡可能(neng)的用交流慢(man)充充電，經常利用直流快充給(gei)電池(chi)組補電，會對電池(chi)壽命有一(yi)定的影響，建(jian)議(yi)養成“慢(man)”的使用習(xi)慣。

4、用車(che)過程(cheng)中(zhong)，起步、上(shang)坡等操作時要盡量(liang)避免(mian)猛(meng)加速，形(xing)成瞬間大電流放電，從而損害電池的物理性能，尤其是車(che)輛“滿載”的情況下。

5、車(che)輛閑置不用(yong)時，電(dian)(dian)池(chi)存儲一般采(cai)用(yong)半電(dian)(dian) 存儲。可以再(zai)30%-60%之間，鋰(li)電(dian)(dian)池(chi)長時間不用(yong)的情況下電(dian)(dian)量會緩慢(man)的衰減（內部鋰(li)離子會回流），車(che)輛廠時間停用(yong)后再(zai)次使用(yong)前，最好對車(che)輛進行一次充(chong)電(dian)(dian)，均衡電(dian)(dian)量。

6、行駛過程中，盡量避免(mian)走坑洼路(lu)面，以免(mian)造成車輛托底電池組保護外(wai)殼(ke)破損。
