新能源汽車能改快充嗎

如(ru)果新能(neng)源汽車原本(ben)沒有快(kuai)充功能(neng)的(de)話是不能(neng)后(hou)期(qi)加(jia)裝(zhuang)的(de)。因(yin)為電池的(de)電壓和電容量的(de)原因(yin)，后(hou)期(qi)加(jia)裝(zhuang)對(dui)車子的(de)使用很不好。

第一(yi)是(shi)因為快(kuai)充的(de)電(dian)(dian)壓很(hen)高，我(wo)們的(de)車輛動力電(dian)(dian)池的(de)容量那么(me)高。第二(er)是(shi)車輛的(de)電(dian)(dian)控管理系統不(bu)具備此功(gong)能。第三是(shi)線(xian)束接口以(yi)及整車控制器，軟(ruan)件(jian)硬(ying)件(jian)都(dou)不(bu)具備快(kuai)充。所以(yi)加裝的(de)話相當于把車子(zi)換新了。很(hen)不(bu)劃算也很(hen)難加裝。

新能源汽車快充和慢充的區別

1、充(chong)電速度不同(tong)

新能源汽車快充(chong)(chong)僅需要一個(ge)小(xiao)時就可以將電(dian)(dian)池充(chong)(chong)到百分之八十的電(dian)(dian)量；新能源汽車慢(man)充(chong)(chong)需要8到10個(ge)小(xiao)時才(cai)能將電(dian)(dian)池電(dian)(dian)量完(wan)全充(chong)(chong)滿。

2、接口不同

快速充電(dian)(dian)(dian)(dian)接(jie)口中(zhong)間(jian)(jian)有(you)(you)兩條母(mu)線(xian)分別為電(dian)(dian)(dian)(dian)源正負，而且在整個充電(dian)(dian)(dian)(dian)過程當中(zhong)電(dian)(dian)(dian)(dian)流(liu)都非(fei)常大所(suo)(suo)(suo)以(yi)母(mu)線(xian)也非(fei)常粗。而慢速充電(dian)(dian)(dian)(dian)則需要(yao)使用到(dao)零線(xian)火(huo)線(xian)還(huan)有(you)(you)地線(xian)三根母(mu)線(xian)，所(suo)(suo)(suo)以(yi)在中(zhong)間(jian)(jian)部位有(you)(you)三條線(xian)，但(dan)是慢速充電(dian)(dian)(dian)(dian)需要(yao)的電(dian)(dian)(dian)(dian)流(liu)并不(bu)高所(suo)(suo)(suo)以(yi)接(jie)口也相對(dui)更細。由于(yu)這兩種充電(dian)(dian)(dian)(dian)接(jie)口不(bu)同，所(suo)(suo)(suo)以(yi)在充電(dian)(dian)(dian)(dian)的時候如果(guo)選擇的充電(dian)(dian)(dian)(dian)樁和車輛不(bu)一致(zhi)，是插不(bu)上(shang)去的。

3、充電原理不同

從充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)原(yuan)理來看快(kuai)速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)和慢速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)存在較大(da)差(cha)異，快(kuai)速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)是(shi)直接(jie)(jie)通(tong)(tong)過(guo)(guo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)樁本身自帶的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)機(ji)將工業用電(dian)(dian)(dian)(dian)轉換為電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)車需要的(de)(de)(de)直流電(dian)(dian)(dian)(dian)，然后(hou)直接(jie)(jie)通(tong)(tong)過(guo)(guo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)槍送入(ru)動(dong)(dong)(dong)力電(dian)(dian)(dian)(dian)池(chi)(chi)。而慢速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)則是(shi)直接(jie)(jie)通(tong)(tong)過(guo)(guo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)槍將220伏(fu)的(de)(de)(de)家用電(dian)(dian)(dian)(dian)送入(ru)到(dao)車載充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)機(ji)，然后(hou)通(tong)(tong)過(guo)(guo)車載充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)機(ji)再把(ba)220伏(fu)的(de)(de)(de)交流電(dian)(dian)(dian)(dian)轉化為車輛需要使用的(de)(de)(de)直流電(dian)(dian)(dian)(dian)然后(hou)再送入(ru)動(dong)(dong)(dong)力電(dian)(dian)(dian)(dian)池(chi)(chi)。所以如果想通(tong)(tong)過(guo)(guo)慢速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)接(jie)(jie)口將充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)樁的(de)(de)(de)直流電(dian)(dian)(dian)(dian)送動(dong)(dong)(dong)力電(dian)(dian)(dian)(dian)池(chi)(chi)這個肯定(ding)是(shi)不(bu)可(ke)能實現的(de)(de)(de)。

4、充(chong)電(dian)(dian)電(dian)(dian)流(liu)不同

快速充(chong)電(dian)(dian)(dian)(dian)(dian)樁(zhuang)也叫(jiao)做直流(liu)(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)樁(zhuang)充(chong)電(dian)(dian)(dian)(dian)(dian)槍輸(shu)出(chu)為(wei)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，而且(qie)充(chong)電(dian)(dian)(dian)(dian)(dian)功(gong)率(lv)都要在15KW以上(shang)，目(mu)前主流(liu)(liu)(liu)的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)樁(zhuang)功(gong)率(lv)在40KW居多。而慢速充(chong)電(dian)(dian)(dian)(dian)(dian)樁(zhuang)也叫(jiao)做交流(liu)(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)樁(zhuang)，這(zhe)種(zhong)充(chong)電(dian)(dian)(dian)(dian)(dian)槍輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)為(wei)交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)同時充(chong)電(dian)(dian)(dian)(dian)(dian)功(gong)率(lv)比較(jiao)低(di)，常見的(de)交流(liu)(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)樁(zhuang)功(gong)率(lv)有(you)3.5KW和7KW兩(liang)種(zhong)。所以想要直接把直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)送(song)入慢充(chong)接口(kou)，強大(da)的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)也會(hui)瞬(shun)間燒(shao)壞充(chong)電(dian)(dian)(dian)(dian)(dian)接口(kou)線路以及車載充(chong)電(dian)(dian)(dian)(dian)(dian)機。

快充與慢充的優缺點

一、慢充優缺點

優點：以較低(di)的速度給設備(bei)電池(chi)充電不僅可以減少熱(re)量和電池(chi)壓力，而(er)且(qie)對電池(chi)的長期(qi)健康(kang)也有好處。

缺點(dian)：缺點(dian)非(fei)常明(ming)顯，充(chong)電時間(jian)較長，僅(jin)滿足(zu)白天運作，晚上休息的車(che)輛。

二(er)、快(kuai)充的(de)優缺(que)點(dian)

優(you)點：充電速度快，相當(dang)節(jie)約時間。

缺點：充電設備安裝要求和成本非常高。快速充電的電流電壓較高，短時間內對電池的沖擊較大，容易令電池的活性物質脫落和電池發熱，無論電池再完美，長期快速充電終究影響電池的使用壽命。

新能源汽車快充電壓多少伏

目(mu)前快充(chong)站的(de)(de)充(chong)電(dian)(dian)樁確實電(dian)(dian)壓(ya)比較高(gao)，例(li)如(ru)一臺240KW的(de)(de)充(chong)電(dian)(dian)樁，它的(de)(de)輸出電(dian)(dian)壓(ya)可以達到750V，電(dian)(dian)流可達480A。而慢(man)充(chong)的(de)(de)交(jiao)流充(chong)電(dian)(dian)樁充(chong)電(dian)(dian)電(dian)(dian)壓(ya)是(shi)220v。至于新能(neng)源車高(gao)壓(ya)充(chong)電(dian)(dian)安全嗎這個問題，現(xian)在的(de)(de)充(chong)電(dian)(dian)樁都會內(nei)置漏電(dian)(dian)保(bao)護(hu)、過壓(ya)保(bao)護(hu)、過流保(bao)護(hu)、溫度檢(jian)測等(deng)功能(neng)，所以安全性還是(shi)有保(bao)障的(de)(de)。
