交流(liu)充(chong)電(dian)(dian)就是(shi)和家用電(dian)(dian)一樣的(de)(de)(de)電(dian)(dian)壓僅(jin)僅(jin)是(shi)充(chong)電(dian)(dian)電(dian)(dian)流(liu)需要(yao)大一些，導線(xian)要(yao)稍微粗一些。直流(liu)充(chong)電(dian)(dian)和交流(liu)充(chong)電(dian)(dian)的(de)(de)(de)區別在于時間(jian)上(shang)面(mian)的(de)(de)(de)不同(tong)，其次充(chong)電(dian)(dian)的(de)(de)(de)電(dian)(dian)流(liu)電(dian)(dian)壓不同(tong)，交流(liu)充(chong)電(dian)(dian)俗稱“慢(man)充(chong)”對(dui)于車(che)輛來說，充(chong)滿電(dian)(dian)的(de)(de)(de)情況(kuang)需要(yao)6到8個小時左右的(de)(de)(de)時間(jian)，其次兩(liang)者之間(jian)的(de)(de)(de)不同(tong)在充(chong)電(dian)(dian)樁(zhuang)上(shang)面(mian)也是(shi)不同(tong)的(de)(de)(de)，今(jin)后(hou)電(dian)(dian)動汽車(che)的(de)(de)(de)規模進一步增(zeng)大，如果多臺直流(liu)大功率樁(zhuang)同(tong)時充(chong)電(dian)(dian)，小區充(chong)電(dian)(dian)樁(zhuang)，對(dui)電(dian)(dian)網的(de)(de)(de)壓力就會(hui)增(zeng)大，這也是(shi)要(yao)考慮(lv)的(de)(de)(de)問題。

交流(liu)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)相當于只是(shi)起了一個(ge)控(kong)制(zhi)電(dian)(dian)(dian)源的(de)(de)作用(yong)(yong)的(de)(de)。稍微復雜一點的(de)(de)就是(shi)在這個(ge)基(ji)礎上增(zeng)加了一些控(kong)制(zhi)開(kai)關和人機(ji)界面處理。可(ke)以對充(chong)(chong)電(dian)(dian)(dian)進行控(kong)制(zhi)，包括充(chong)(chong)電(dian)(dian)(dian)時間，充(chong)(chong)電(dian)(dian)(dian)量(liang)以及開(kai)機(ji)停機(ji)和保護等措施。交流(liu)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)，本質(zhi)就是(shi)一個(ge)帶控(kong)制(zhi)的(de)(de)插座，輸出(chu)的(de)(de)是(shi)交流(liu)電(dian)(dian)(dian)，需要車(che)載充(chong)(chong)電(dian)(dian)(dian)機(ji)自(zi)己(ji)進行變壓整流(liu)，單管的(de)(de)汽車(che)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)使用(yong)(yong)10平方的(de)(de)主線即(ji)可(ke)，這也是(shi)交流(liu)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)目前受歡迎的(de)(de)原因。
