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(dian)動(dong)工程機械充電(dian)的，那(nei)么它是直流充電(dian)樁還是交流充電(dian)樁呢(ni)？

據了解，一般工程機(ji)械充(chong)(chong)(chong)電(dian)(dian)(dian)樁(zhuang)都是直(zhi)流充(chong)(chong)(chong)電(dian)(dian)(dian)樁(zhuang)，因為直(zhi)流充(chong)(chong)(chong)電(dian)(dian)(dian)樁(zhuang)充(chong)(chong)(chong)電(dian)(dian)(dian)速度更快，工程機(ji)械載重(zhong)量大、電(dian)(dian)(dian)池容量也大，用(yong)交(jiao)流充(chong)(chong)(chong)電(dian)(dian)(dian)樁(zhuang)的話充(chong)(chong)(chong)電(dian)(dian)(dian)速度慢，會(hui)耽(dan)誤工程進度，因此工程機(ji)械充(chong)(chong)(chong)電(dian)(dian)(dian)樁(zhuang)普遍都是大功率直(zhi)流充(chong)(chong)(chong)電(dian)(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)(gong)程(cheng)機(ji)械(xie)充(chong)電樁是大(da)(da)功率(lv)(lv)直流充(chong)電樁，用單(dan)相電的(de)話帶不(bu)動(dong)，因為功率(lv)(lv)太大(da)(da)了(le)，一(yi)般常見的(de)工(gong)(gong)(gong)程(cheng)機(ji)械(xie)充(chong)電樁是采用的(de)三相四線制供(gong)電，可以提供(gong)足夠(gou)的(de)功率(lv)(lv)，輸出的(de)電壓和電流調整范(fan)圍大(da)(da)，從而滿足為工(gong)(gong)(gong)程(cheng)機(ji)械(xie)快速充(chong)電的(de)要求。

三、工程機械充電樁是220v還是380v

380V。

充電樁有220V和380V兩種(zhong)，一般220V主要是普通(tong)家用(yong)(yong)新能源汽車(che)使用(yong)(yong)，充電速度較慢；工程機械充電樁是直流快充，電壓為(wei)380V。
