慢速(su)充電：

優點(dian)：由于所用功率和(he)電(dian)(dian)(dian)(dian)流的額(e)定值并不關鍵(jian)，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器的安裝(zhuang)成本相對較低；它可(ke)以(yi)充(chong)(chong)(chong)分(fen)利用低電(dian)(dian)(dian)(dian)量時(shi)段(duan)進(jin)行(xing)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，降低充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)成本；可(ke)以(yi)提高充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)效率，延(yan)長(chang)電(dian)(dian)(dian)(dian)池的使用壽命。

缺點：常規充(chong)(chong)電方式的主要(yao)(yao)缺點是充(chong)(chong)電時間過長，難(nan)以滿足應(ying)急運行要(yao)(yao)求。

充：

優點(dian)：充(chong)電(dian)時間(jian)短，大容量充(chong)電(dian)，幾(ji)分鐘就能充(chong)完(wan)70%-80%的電(dian)。

缺(que)點：快(kuai)充(chong)(chong)充(chong)(chong)電器與(yu)常(chang)規充(chong)(chong)電方式相比(bi)，充(chong)(chong)電效(xiao)率較(jiao)低(di)，相應(ying)的工作和(he)安(an)裝(zhuang)費用較(jiao)高；由于充(chong)(chong)電速度快(kuai)，充(chong)(chong)電電流大，對充(chong)(chong)電技術和(he)安(an)全性提出了(le)更高的要(yao)求(qiu)，計量充(chong)(chong)電的設計也需要(yao)特別考慮。

無論是(shi)充(chong)(chong)(chong)電口(kou)(kou)還是(shi)充(chong)(chong)(chong)電槍(qiang)(qiang)，它們的(de)大小、孔數(shu)、孔徑都不一(yi)樣。從外觀上(shang)看，快充(chong)(chong)(chong)口(kou)(kou)比慢充(chong)(chong)(chong)口(kou)(kou)大，對應的(de)孔徑(充(chong)(chong)(chong)電槍(qiang)(qiang)線)也更大。DC快充(chong)(chong)(chong)口(kou)(kou)的(de)孔數(shu)是(shi)5個，交流慢充(chong)(chong)(chong)口(kou)(kou)是(shi)7個。試想(xiang)一(yi)下(xia)，一(yi)大圈(quan)的(de)DC充(chong)(chong)(chong)電槍(qiang)(qiang)怎么能插到(dao)一(yi)個小圈(quan)的(de)慢充(chong)(chong)(chong)口(kou)(kou)呢？更有甚者，它們的(de)孔的(de)數(shu)量(liang)和間距(ju)都不一(yi)樣，根本連不上(shang)。如果(guo)充(chong)(chong)(chong)電槍(qiang)(qiang)連不上(shang)充(chong)(chong)(chong)電口(kou)(kou)，充(chong)(chong)(chong)電就無從談起(qi)。

DC充電樁啟動時，利用充電樁內置的轉換模塊將電網的交流電直接轉換成DC電能，通過電動車的充電口給電池充電。交流充電樁是將電網的交流電通過充電口和車載充電器轉換成DC電能，然后給蓄電池充電的一種充電方式。如果DC充電槍可以插入慢速充電端口，由于DC快速充電端口連接到車載充電器，車載充電器的DC輸入不是交流電。
