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門給電動工程(cheng)機械充電的(de)，那么它是直流充電樁(zhuang)還是交流充電樁(zhuang)呢？

據了解，一(yi)般(ban)工(gong)程機(ji)械(xie)充(chong)電(dian)(dian)(dian)(dian)樁都是直流(liu)(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)樁，因(yin)為直流(liu)(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)樁充(chong)電(dian)(dian)(dian)(dian)速度更快，工(gong)程機(ji)械(xie)載重量大(da)、電(dian)(dian)(dian)(dian)池容量也大(da)，用交流(liu)(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)樁的話充(chong)電(dian)(dian)(dian)(dian)速度慢，會耽誤(wu)工(gong)程進度，因(yin)此工(gong)程機(ji)械(xie)充(chong)電(dian)(dian)(dian)(dian)樁普遍都是大(da)功(gong)率直流(liu)(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)樁。

二、工程機械充電樁是單相電還是三相電

三相電。

工(gong)程機械(xie)充電(dian)(dian)(dian)樁(zhuang)是大功率(lv)直流充電(dian)(dian)(dian)樁(zhuang)，用(yong)(yong)單相(xiang)電(dian)(dian)(dian)的話帶不動，因為(wei)功率(lv)太大了(le)，一般常見的工(gong)程機械(xie)充電(dian)(dian)(dian)樁(zhuang)是采用(yong)(yong)的三(san)相(xiang)四線制供(gong)電(dian)(dian)(dian)，可(ke)以(yi)提(ti)供(gong)足夠的功率(lv)，輸(shu)出的電(dian)(dian)(dian)壓和電(dian)(dian)(dian)流調整范圍大，從(cong)而滿(man)足為(wei)工(gong)程機械(xie)快速充電(dian)(dian)(dian)的要求。

三、工程機械充電樁是220v還是380v

380V。

充(chong)電(dian)樁有220V和380V兩種，一般(ban)220V主要是普通家用(yong)新能源(yuan)汽車使用(yong)，充(chong)電(dian)速度較慢(man)；工(gong)程機械充(chong)電(dian)樁是直流快充(chong)，電(dian)壓(ya)為380V。
