大部分新能源汽車，一般都支持交流充電和直流充電。那么，作為新能源車主，要給愛車配一臺充電(dian)樁，該如何(he)選擇“慢充”和(he)“快充”，兩者(zhe)之間又有怎樣(yang)的區(qu)別(bie)呢？

“慢充(chong)(chong)”主要指使用交(jiao)流電(dian)(dian)的(de)(de)(de)充(chong)(chong)電(dian)(dian)樁(zhuang)，充(chong)(chong)電(dian)(dian)過程中要經過新能源車配(pei)備的(de)(de)(de)車載(zai)充(chong)(chong)電(dian)(dian)機，因為充(chong)(chong)電(dian)(dian)速度較(jiao)慢，所(suo)以被叫做“慢充(chong)(chong)”。在(zai)國標(biao)接(jie)口，“慢充(chong)(chong)”中對應的(de)(de)(de)是7孔國標(biao)接(jie)口，目(mu)前(qian)比較(jiao)常見的(de)(de)(de)交(jiao)流充(chong)(chong)電(dian)(dian)樁(zhuang)為單相7kW，充(chong)(chong)電(dian)(dian)功率較(jiao)小(xiao)，但(dan)也有類似40kW等(deng)有較(jiao)大(da)充(chong)(chong)電(dian)(dian)功率的(de)(de)(de)三相交(jiao)流充(chong)(chong)電(dian)(dian)樁(zhuang)。

“快(kuai)充(chong)(chong)(chong)(chong)”主(zhu)要(yao)指(zhi)使用(yong)直流(liu)的充(chong)(chong)(chong)(chong)電(dian)(dian)樁(zhuang)，充(chong)(chong)(chong)(chong)電(dian)(dian)過程中(zhong)(zhong)不需要(yao)經過新能源車配備的車載(zai)充(chong)(chong)(chong)(chong)電(dian)(dian)機，因為充(chong)(chong)(chong)(chong)電(dian)(dian)速(su)度較快(kuai)，所(suo)以(yi)被叫做“快(kuai)充(chong)(chong)(chong)(chong)”。“快(kuai)充(chong)(chong)(chong)(chong)”在國(guo)標接(jie)口中(zhong)(zhong)，對應的9孔國(guo)標接(jie)口，較常見(jian)為80kW以(yi)及(ji)120kW直流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)樁(zhuang)，主(zhu)要(yao)用(yong)于(yu)小型(xing)電(dian)(dian)動汽車。此外，還(huan)有一些配備液冷系統的充(chong)(chong)(chong)(chong)電(dian)(dian)樁(zhuang)，單槍功率(lv)可達600kW。

在(zai)“快(kuai)充”和“慢充”的選擇(ze)上

兩者各有優缺點

充電耐用方面

“慢充(chong)(chong)”充(chong)(chong)電(dian)(dian)比“快(kuai)充(chong)(chong)”充(chong)(chong)電(dian)(dian)更耐用一些，“快(kuai)充(chong)(chong)”雖(sui)然充(chong)(chong)電(dian)(dian)快(kuai)但(dan)同樣也會導致電(dian)(dian)池內的(de)虛電(dian)(dian)變多。至于大功率的(de)40kW三(san)相交流充(chong)(chong)電(dian)(dian)，其實也是因車而(er)異，有的(de)車型(xing)只支持(chi)單相充(chong)(chong)電(dian)(dian)，那么對于這類車型(xing)來(lai)講(jiang)，40kW的(de)三(san)相充(chong)(chong)電(dian)(dian)樁最(zui)多只能提供7kW的(de)充(chong)(chong)電(dian)(dian)功率。

電池壽命方面

“快充(chong)”充(chong)電(dian)功(gong)率較大(da)(da)，但(dan)對電(dian)池的壽命(ming)有影(ying)響，所以在(zai)充(chong)電(dian)時建議大(da)(da)家把電(dian)池的電(dian)量（SOC）保(bao)持在(zai)20%-90%之(zhi)間。充(chong)電(dian)到最后(hou)10%，汽車BMS也會為了保(bao)護電(dian)池而降低充(chong)電(dian)功(gong)率，使(shi)充(chong)電(dian)速(su)度放(fang)緩，可能你充(chong)電(dian)前面(mian)90%的時間與這最后(hou)10%的時間相同。

所以(yi)，小編推介大家(jia)采(cai)(cai)用快慢充(chong)(chong)結(jie)合的方(fang)式進(jin)行充(chong)(chong)電(dian)(dian)：時間比(bi)較寬松的時候，采(cai)(cai)用慢充(chong)(chong)充(chong)(chong)電(dian)(dian)，既(ji)能保護電(dian)(dian)池(chi)又(you)可很(hen)好的利用低谷低價電(dian)(dian)，節(jie)約充(chong)(chong)電(dian)(dian)費用。在需要及時補(bu)充(chong)(chong)電(dian)(dian)源(yuan)時，如高速(su)途(tu)中，利用快充(chong)(chong)充(chong)(chong)電(dian)(dian)可對電(dian)(dian)池(chi)進(jin)行快速(su)的補(bu)給。
