在電(dian)(dian)池(chi)兩端接有電(dian)(dian)池(chi)管(guan)理系(xi)統(BMS)，這是直流(liu)充(chong)(chong)(chong)電(dian)(dian)的(de)技術，可以(yi)說這就是電(dian)(dian)池(chi)管(guan)家，可以(yi)預(yu)防很多不安全因(yin)素(su)，提高(gao)電(dian)(dian)池(chi)的(de)性能和(he)壽命(ming)。電(dian)(dian)動汽車充(chong)(chong)(chong)電(dian)(dian)樁作為電(dian)(dian)動汽車的(de)補給裝置(zhi)，充(chong)(chong)(chong)電(dian)(dian)性能關系(xi)到(dao)電(dian)(dian)池(chi)組(zu)的(de)使用壽命(ming)、充(chong)(chong)(chong)電(dian)(dian)時間。這也是消(xiao)費者在買電(dian)(dian)動汽車前(qian)關心的(de)一方(fang)面。交(jiao)流(liu)充(chong)(chong)(chong)電(dian)(dian)樁（栓）應(ying)具備急停開關，可通過手動或遠方(fang)通信的(de)方(fang)式緊急停止(zhi)充(chong)(chong)(chong)電(dian)(dian)；交(jiao)流(liu)充(chong)(chong)(chong)電(dian)(dian)樁應(ying)具備輸出(chu)側過流(liu)和(he)短路保護功能。

交流(liu)(liu)充(chong)電(dian)(dian)(dian)樁(zhuang)與直流(liu)(liu)充(chong)電(dian)(dian)(dian)樁(zhuang)本質區別是是否包含(han)充(chong)電(dian)(dian)(dian)機，這也是直流(liu)(liu)充(chong)電(dian)(dian)(dian)樁(zhuang)為什么叫(jiao)作非(fei)車載(zai)充(chong)電(dian)(dian)(dian)機的(de)(de)原因。同(tong)樣的(de)(de)道理，交流(liu)(liu)充(chong)電(dian)(dian)(dian)樁(zhuang)可以稱為車載(zai)充(chong)電(dian)(dian)(dian)機。針對充(chong)電(dian)(dian)(dian)樁(zhuang)充(chong)電(dian)(dian)(dian)設施可能發(fa)生的(de)(de)生產安(an)全事(shi)故的(de)(de)特(te)點和危害，進行風險(xian)辨識、評估和應(ying)(ying)急(ji)資源調查(cha)，制定完善本單位事(shi)故應(ying)(ying)急(ji)預案。交流(liu)(liu)充(chong)電(dian)(dian)(dian)樁(zhuang)（栓）應(ying)(ying)具備(bei)急(ji)停(ting)(ting)開關，可通過手動或遠方通信(xin)的(de)(de)方式緊急(ji)停(ting)(ting)止充(chong)電(dian)(dian)(dian)；交流(liu)(liu)充(chong)電(dian)(dian)(dian)樁(zhuang)應(ying)(ying)具備(bei)輸出(chu)側過流(liu)(liu)和短路保(bao)護功能。

實際上(shang)，交流充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)更加受歡迎，首先(xian)交流充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)成(cheng)本低，施工(gong)也比較(jiao)簡單，對變壓器(qi)的(de)(de)負荷也不是很大，汽車充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)一(yi)(yi)個多少錢，小(xiao)區的(de)(de)配電(dian)(dian)(dian)(dian)柜都可(ke)以(yi)(yi)直(zhi)接去(qu)電(dian)(dian)(dian)(dian)安(an)裝(zhuang)。從使用(yong)者(zhe)角度考(kao)慮，目(mu)前交流充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)還是非常受歡迎的(de)(de)，也是現在(zai)小(xiao)區安(an)裝(zhuang)的(de)(de)主流設備(bei)(bei)，設備(bei)(bei)成(cheng)本低，安(an)裝(zhuang)條件比較(jiao)簡單，充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)一(yi)(yi)般提供(gong)常規充(chong)(chong)電(dian)(dian)(dian)(dian)和快速充(chong)(chong)電(dian)(dian)(dian)(dian)兩種充(chong)(chong)電(dian)(dian)(dian)(dian)方(fang)式(shi)，人們可(ke)以(yi)(yi)使用(yong)特定的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)卡(ka)在(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)提供(gong)的(de)(de)人機(ji)交互操(cao)(cao)作界(jie)面上(shang)使用(yong)，進(jin)行相應的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)方(fang)式(shi)、充(chong)(chong)電(dian)(dian)(dian)(dian)時間、費用(yong)數據打印等操(cao)(cao)作，充(chong)(chong)電(dian)(dian)(dian)(dian)樁(zhuang)(zhuang)顯示屏(ping)能顯示充(chong)(chong)電(dian)(dian)(dian)(dian)量、費用(yong)、充(chong)(chong)電(dian)(dian)(dian)(dian)時間等數據。
