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(shi)專(zhuan)門給電動工程機械充(chong)電的，那么它是(shi)直流充(chong)電樁還是(shi)交流充(chong)電樁呢(ni)？

據了解，一般工(gong)程(cheng)(cheng)機(ji)械(xie)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)都是(shi)直(zhi)流充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)，因為直(zhi)流充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)充(chong)(chong)電(dian)(dian)(dian)速度(du)(du)(du)更快，工(gong)程(cheng)(cheng)機(ji)械(xie)載重量大、電(dian)(dian)(dian)池容量也大，用交流充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)的話充(chong)(chong)電(dian)(dian)(dian)速度(du)(du)(du)慢，會耽誤工(gong)程(cheng)(cheng)進(jin)度(du)(du)(du)，因此工(gong)程(cheng)(cheng)機(ji)械(xie)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)普(pu)遍(bian)都是(shi)大功率直(zhi)流充(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。

工程機械(xie)充電(dian)(dian)樁是大(da)(da)功率(lv)直流充電(dian)(dian)樁，用(yong)(yong)單相電(dian)(dian)的(de)(de)(de)話帶不(bu)動，因為(wei)功率(lv)太大(da)(da)了(le)，一(yi)般常(chang)見(jian)的(de)(de)(de)工程機械(xie)充電(dian)(dian)樁是采用(yong)(yong)的(de)(de)(de)三相四線制供電(dian)(dian)，可以(yi)提供足夠的(de)(de)(de)功率(lv)，輸出(chu)的(de)(de)(de)電(dian)(dian)壓和電(dian)(dian)流調(diao)整范圍(wei)大(da)(da)，從(cong)而滿(man)足為(wei)工程機械(xie)快速充電(dian)(dian)的(de)(de)(de)要求。

三、工程機械充電樁是220v還是380v

380V。

充(chong)電樁有(you)220V和380V兩種，一般(ban)220V主要(yao)是(shi)普通家用新能源汽車使用，充(chong)電速度較慢；工程(cheng)機械(xie)充(chong)電樁是(shi)直流快充(chong)，電壓(ya)為380V。
