新能源車使用的電池主要是磷酸鐵鋰電池和(he)三元(yuan)鋰(li)電池兩大(da)類，而電池快充(chong)(chong)一(yi)(yi)直(zhi)是(shi)(shi)行業(ye)熱議(yi)的(de)問(wen)題(ti)，也是(shi)(shi)一(yi)(yi)直(zhi)在改善提(ti)升的(de)進程中，但很(hen)多朋友不(bu)知道的(de)是(shi)(shi)，其實現在的(de)新能源汽車(che)是(shi)(shi)同時(shi)具備快充(chong)(chong)和(he)慢(man)充(chong)(chong)兩大(da)技術(shu)的(de)，而大(da)部(bu)分車(che)主在緊急用電時(shi)都(dou)會考慮快充(chong)(chong)，只(zhi)不(bu)過長期快充(chong)(chong)自(zi)然是(shi)(shi)會傷(shang)電池的(de)，所以日常(chang)需求(qiu)還是(shi)(shi)選擇(ze)普通慢(man)充(chong)(chong)會更(geng)好。下面，我(wo)們來看(kan)看(kan)帶(dai)來的(de)新能源車(che)快充(chong)(chong)跟(gen)慢(man)充(chong)(chong)有(you)什么區(qu)別吧！

新(xin)能源車快充(chong)對電池有(you)傷害嗎

新能源汽車電池(chi)使用(yong)快充(chong)(chong)功能時(shi)與使用(yong)慢充(chong)(chong)時(shi)對(dui)電池(chi)傷(shang)害會(hui)更(geng)大些，關鍵是損(sun)壞是否(fou)(fou)過大，也就是損(sun)害是否(fou)(fou)超過電池(chi)的理論(lun)損(sun)害值，超過的話(hua)，是會(hui)影響電池(chi)的使用(yong)壽命(ming)（理論(lun)使用(yong)時(shi)長長短）。

首先，快充是(shi)電流會更(geng)大(da)，更(geng)容易造成電池發熱不(bu)均，一旦發生熱失控(kong)，就(jiu)有起(qi)火的危險。

其次，快充是將離子從正極(ji)快速(su)插入負極(ji)，以(yi)增加離子的流量(liang)和速(su)度(du)。這會引起電極(ji)濃(nong)差(cha)極(ji)化現象，最終導致電極(ji)材(cai)料的破(po)壞(huai)。快充使用的時間越長(chang)，對(dui)電極(ji)材(cai)料的破(po)壞(huai)就越嚴重。

但是話雖如此，電(dian)池(chi)也沒有那(nei)么嬌氣，而且現在大多數電(dian)池(chi)都受(shou)到(dao)保護(hu)。例如，BMS系統(tong)具有對(dui)電(dian)池(chi)中心(xin)各個模塊的監控、部署、維護(hu)和保護(hu)。目的是防止過充(chong)過放，延長電(dian)池(chi)壽(shou)命，幫助電(dian)池(chi)正常(chang)工作(zuo)。

新能源汽車的(de)(de)電(dian)(dian)(dian)(dian)池(chi)快(kuai)充(chong)(chong)是指大功率直流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)。利用(yong)直流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)樁的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)接口(kou)(kou)，將電(dian)(dian)(dian)(dian)網的(de)(de)交流(liu)(liu)電(dian)(dian)(dian)(dian)轉(zhuan)換成直流(liu)(liu)電(dian)(dian)(dian)(dian)，傳輸(shu)到電(dian)(dian)(dian)(dian)動汽車的(de)(de)快(kuai)速充(chong)(chong)電(dian)(dian)(dian)(dian)口(kou)(kou)，電(dian)(dian)(dian)(dian)能直接進(jin)入(ru)電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)。只需半(ban)小時即可將其充(chong)(chong)電(dian)(dian)(dian)(dian)至(zhi) 80%。

慢(man)充(chong)(chong)(chong)是指交(jiao)流充(chong)(chong)(chong)電(dian)(dian)。是交(jiao)流充(chong)(chong)(chong)電(dian)(dian)樁(zhuang)的(de)充(chong)(chong)(chong)電(dian)(dian)接(jie)口(kou)，電(dian)(dian)網的(de)交(jiao)流電(dian)(dian)輸(shu)入到(dao)電(dian)(dian)動汽(qi)車(che)(che)(che)的(de)慢(man)充(chong)(chong)(chong)端口(kou)，交(jiao)流電(dian)(dian)通(tong)過(guo)車(che)(che)(che)內(nei)的(de)充(chong)(chong)(chong)電(dian)(dian)器(qi)轉(zhuan)換成直流電(dian)(dian)，再輸(shu)入到(dao)電(dian)(dian)池中完成充(chong)(chong)(chong)電(dian)(dian)。一般的(de)車(che)(che)(che)型需要6到(dao)8個(ge)小時才(cai)能將電(dian)(dian)池充(chong)(chong)(chong)滿。

新能源汽(qi)車(che)一直用快(kuai)充好嗎

新能源汽車(che)慢充(chong)(chong)比(bi)頻繁(fan)充(chong)(chong)電(dian)好(hao)，因(yin)為慢充(chong)(chong)的充(chong)(chong)電(dian)時(shi)間雖然長，但對電(dian)池的傷害(hai)小，一般是晚上充(chong)(chong)電(dian)，第二天早上就充(chong)(chong)滿。

快(kuai)(kuai)充(chong)只在緊急情況下使用，比如(ru)高速運(yun)行，電量用完不到一半，所(suo)以選擇使用快(kuai)(kuai)充(chong)，因為慢(man)充(chong)需(xu)要很(hen)長時(shi)間。

車企(qi)在生(sheng)產汽車時將這兩(liang)種充(chong)電(dian)模式都設計在汽車上的原(yuan)因(yin)之一是，快(kuai)充(chong)只是應急(ji)用，而慢充(chong)通常是盡量使(shi)用。快(kuai)充(chong)對電(dian)池(chi)的影響(xiang)很大，所(suo)以通常不建議使(shi)用快(kuai)充(chong)。

長(chang)期快充(chong)(chong)肯定會損壞動(dong)力(li)電(dian)(dian)(dian)池(chi)(chi)。畢竟快充(chong)(chong)本身使用(yong)(yong)的(de)是(shi)大(da)電(dian)(dian)(dian)流充(chong)(chong)電(dian)(dian)(dian)，很容易導致過(guo)熱過(guo)充(chong)(chong)。很多動(dong)力(li)電(dian)(dian)(dian)池(chi)(chi)因為快充(chong)(chong)模式(shi)會自(zi)燃(ran)。從這個角度(du)來(lai)說，應(ying)該可以(yi)直觀的(de)了(le)解快充(chong)(chong)，尤其是(shi)長(chang)時間快充(chong)(chong)對(dui)動(dong)力(li)電(dian)(dian)(dian)池(chi)(chi)造(zao)成的(de)傷害(hai)。但(dan)新能源(yuan)汽(qi)車到底是(shi)快充(chong)(chong)還(huan)是(shi)慢(man)充(chong)(chong)，必須根(gen)據一定的(de)使用(yong)(yong)場景(jing)來(lai)討論。滿足當前用(yong)(yong)戶(hu)充(chong)(chong)電(dian)(dian)(dian)需求的(de)充(chong)(chong)電(dian)(dian)(dian)方式(shi)，才是(shi)好的(de)充(chong)(chong)電(dian)(dian)(dian)方式(shi)。
