充電(dian)樁其功能類(lei)似于加油站(zhan)里面的(de)加油機，可以固定在地面或墻 壁，安裝于公(gong)共建筑（公(gong)共樓宇、商(shang)場、公(gong)共停車(che)場等）和居民小區 停車(che)場或充電(dian)站(zhan)內，可以根(gen)據不同的(de)電(dian)壓等級(ji)為各(ge)種型號的(de)電(dian)動汽車(che)充電(dian)。

充(chong)電(dian)(dian)樁(zhuang)的輸入端與交流(liu)(liu)電(dian)(dian)網直接(jie)(jie)連(lian)接(jie)(jie)，輸出端都裝(zhuang)有充(chong)電(dian)(dian)插(cha)頭 用(yong)于(yu)為電(dian)(dian)動汽(qi)車充(chong)電(dian)(dian)。根據充(chong)電(dian)(dian)方式可以(yi)分(fen)(fen)有交流(liu)(liu)充(chong)電(dian)(dian)樁(zhuang)、直流(liu)(liu)充(chong)電(dian)(dian)樁(zhuang)、無線(xian)充(chong)電(dian)(dian)。按時間也可以(yi)分(fen)(fen)有快充(chong)、慢(man)充(chong)、換(huan)電(dian)(dian)。

電(dian)(dian)(dian)動汽車(che)是指以車(che)載電(dian)(dian)(dian)源為(wei)動力(li)，用電(dian)(dian)(dian)機驅動車(che)輪(lun)行駛， 符合道路交(jiao)通(tong)、安全法規各項要求的車(che)輛。

它使用存(cun)儲在電(dian)(dian)池(chi)中(zhong)的電(dian)(dian)來發動。存(cun)儲電(dian)(dian)池(chi)就必須充(chong)電(dian)(dian)設備為(wei)它充(chong)電(dian)(dian)。那么(me)電(dian)(dian)動汽(qi)車充(chong)電(dian)(dian)設施是電(dian)(dian)動汽(qi) 車產業鏈的重(zhong)要(yao)組成部分。目前為(wei)電(dian)(dian)動汽(qi)車充(chong)電(dian)(dian)設施主要(yao)是充(chong)電(dian)(dian)站(zhan)和充(chong)站(zhan)樁。

充電(dian)(dian)站(zhan)按照(zhao) 功能(neng)可以劃分(fen)為四個子模塊：配電(dian)(dian)系統、充電(dian)(dian)系統、電(dian)(dian)池調度系統、充電(dian)(dian)站(zhan)監控系統。充電(dian)(dian)系統的核心也是充電(dian)(dian)樁。

從上圖可(ke)以看到，大部分(fen)電(dian)動車(che)(che)的續航能(neng)力才100多(duo)公里(li)，所(suo)以續航里(li)程就成了新能(neng)源(yuan)電(dian)動車(che)(che)在發展過(guo)程中遇到的最大障礙(ai)，而要想保證電(dian)動車(che)(che)的正常行駛(shi)，就要修建(jian)足夠多(duo)的充(chong)電(dian)站，方便(bian)人們在駕 駛(shi)電(dian)動車(che)(che)出行時充(chong)電(dian)。“兵馬未(wei)動，糧草先(xian)行”,優先(xian)建(jian)設充(chong)電(dian)站，是新能(neng)源(yuan)汽(qi)車(che)(che)發展的先(xian)決(jue)條件。這(zhe)個關系是不可(ke)顛倒的。
