充(chong)電(dian)樁其功能類似于加油(you)站里面的(de)加油(you)機，可(ke)以固(gu)定在地(di)面或(huo)墻(qiang)壁，安裝于公(gong)(gong)共建筑（公(gong)(gong)共樓宇(yu)、商場、公(gong)(gong)共停(ting)(ting)車(che)(che)場等）和居民(min)小區停(ting)(ting)車(che)(che)場或(huo)充(chong)電(dian)站內，可(ke)以根據不(bu)同的(de)電(dian)壓等級(ji)為各(ge)種型(xing)號的(de)電(dian)動汽車(che)(che)充(chong)電(dian)。充(chong)電(dian)樁的(de)輸入端與交流電(dian)網直接連(lian)接，輸出(chu)端都裝有充(chong)電(dian)插頭用(yong)于為電(dian)動汽車(che)(che)充(chong)電(dian)

充(chong)(chong)(chong)(chong)(chong)電(dian)樁(zhuang)一般(ban)提供常規(gui)充(chong)(chong)(chong)(chong)(chong)電(dian)和快速充(chong)(chong)(chong)(chong)(chong)電(dian)兩(liang)種充(chong)(chong)(chong)(chong)(chong)電(dian)方(fang)式，人們可以使用特定的充(chong)(chong)(chong)(chong)(chong)電(dian)卡在(zai)充(chong)(chong)(chong)(chong)(chong)電(dian)樁(zhuang)提供的人機交(jiao)互(hu)操作界面上(shang)刷卡使用，進(jin)行相應的充(chong)(chong)(chong)(chong)(chong)電(dian)方(fang)式、充(chong)(chong)(chong)(chong)(chong)電(dian)時(shi)間(jian)、費(fei)用數據打印等操作，充(chong)(chong)(chong)(chong)(chong)電(dian)樁(zhuang)顯(xian)示(shi)屏能顯(xian)示(shi)充(chong)(chong)(chong)(chong)(chong)電(dian)量、費(fei)用、充(chong)(chong)(chong)(chong)(chong)電(dian)時(shi)間(jian)等數據。

政府大力度的扶持和推進，刺激了眾多企業對于充電樁產業的期待。 一位行業人士表示，除了國家電網、南方電網、中石化等能源巨頭外，呈貢戶外開閉所汽車企業和電氣生產企業積極性都很高。戶外開閉所廠家像比(bi)亞(ya)迪、北(bei)汽(qi)這(zhe)類(lei)電(dian)動車(che)企業(ye)(ye)早已開(kai)(kai)始(shi)建設通用充(chong)電(dian)樁，許繼電(dian)氣、西(xi)門子這(zhe)類(lei)行業(ye)(ye)內企業(ye)(ye)也已開(kai)(kai)始(shi)開(kai)(kai)發或投資充(chong)電(dian)站的建設。按照相(xiang)關測算(suan)，未來5年(nian)(nian)(nian)內，充(chong)電(dian)站的營業(ye)(ye)規模每年(nian)(nian)(nian)有望(wang)超過千(qian)億。從國家今年(nian)(nian)(nian)的各(ge)項(xiang)動作來看(kan)，電(dian)動車(che)的充(chong)電(dian)基礎設施建設將在今年(nian)(nian)(nian)爆發。

配(pei)電(dian)(dian)箱的(de)(de)進(jin)出線(xian)選用低(di)壓電(dian)(dian)纜(lan)(lan)(lan)，電(dian)(dian)纜(lan)(lan)(lan)的(de)(de)選擇應符合技術要(yao)求(qiu)。例如30kVA、50kVA變壓器的(de)(de)配(pei)電(dian)(dian)箱的(de)(de)進(jin)線(xian)使(shi)用VV22-35×4電(dian)(dian)纜(lan)(lan)(lan)，分(fen)路(lu)出線(xian)使(shi)用同規(gui)格的(de)(de)VLV22-35×4電(dian)(dian)纜(lan)(lan)(lan)；80kVA、100kVA變壓器的(de)(de)配(pei)電(dian)(dian)箱的(de)(de)進(jin)線(xian)分(fen)別(bie)使(shi)用VV22-50×4、VV22-70×4電(dian)(dian)纜(lan)(lan)(lan)，分(fen)路(lu)出線(xian)分(fen)別(bie)使(shi)用VLV22-50×4、VLV22-70×4電(dian)(dian)纜(lan)(lan)(lan),其電(dian)(dian)纜(lan)(lan)(lan)與(yu)銅鋁接線(xian)鼻壓接后再(zai)用螺栓與(yu)配(pei)電(dian)(dian)箱內(nei)接線(xian)樁頭連接。
