一、工程機械充電樁是直流還是交流

充電樁有交流充電樁和直流充電樁之分，二者在充電效率方面有一定的差異，工程機械充電樁是專(zhuan)門給電(dian)動工程機械充(chong)電(dian)的，那(nei)么它是直(zhi)流(liu)充(chong)電(dian)樁還是交流(liu)充(chong)電(dian)樁呢？

據了解(jie)，一般(ban)工(gong)(gong)(gong)程機(ji)械(xie)(xie)充(chong)(chong)(chong)電(dian)(dian)樁(zhuang)都(dou)是直流(liu)充(chong)(chong)(chong)電(dian)(dian)樁(zhuang)，因為(wei)直流(liu)充(chong)(chong)(chong)電(dian)(dian)樁(zhuang)充(chong)(chong)(chong)電(dian)(dian)速(su)度更快，工(gong)(gong)(gong)程機(ji)械(xie)(xie)載重量大(da)、電(dian)(dian)池容量也大(da)，用交(jiao)流(liu)充(chong)(chong)(chong)電(dian)(dian)樁(zhuang)的話(hua)充(chong)(chong)(chong)電(dian)(dian)速(su)度慢(man)，會耽誤工(gong)(gong)(gong)程進(jin)度，因此工(gong)(gong)(gong)程機(ji)械(xie)(xie)充(chong)(chong)(chong)電(dian)(dian)樁(zhuang)普遍都(dou)是大(da)功率直流(liu)充(chong)(chong)(chong)電(dian)(dian)樁(zhuang)。

二、工程機械充電樁是單相電還是三相電

三相電。

工(gong)(gong)程(cheng)機(ji)(ji)(ji)械充電樁是(shi)大(da)功(gong)率直流充電樁，用單相(xiang)電的(de)(de)話帶不動，因為(wei)(wei)功(gong)率太大(da)了，一般常見(jian)的(de)(de)工(gong)(gong)程(cheng)機(ji)(ji)(ji)械充電樁是(shi)采用的(de)(de)三相(xiang)四線制供電，可(ke)以提供足夠的(de)(de)功(gong)率，輸出的(de)(de)電壓和電流調整(zheng)范圍大(da)，從而滿(man)足為(wei)(wei)工(gong)(gong)程(cheng)機(ji)(ji)(ji)械快速(su)充電的(de)(de)要求。

三、工程機械充電樁是220v還是380v

380V。

充(chong)(chong)(chong)電樁有220V和380V兩(liang)種，一般220V主要是普通(tong)家用新(xin)能(neng)源汽(qi)車使用，充(chong)(chong)(chong)電速度較慢(man)；工程(cheng)機械充(chong)(chong)(chong)電樁是直流快充(chong)(chong)(chong)，電壓為380V。
