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(gei)電動(dong)工程機械充電的，那么它是(shi)直流充電樁還是(shi)交流充電樁呢？

據了解(jie)，一般工(gong)程(cheng)機(ji)械(xie)充(chong)(chong)電(dian)(dian)樁(zhuang)(zhuang)(zhuang)都(dou)是直(zhi)流充(chong)(chong)電(dian)(dian)樁(zhuang)(zhuang)(zhuang)，因為直(zhi)流充(chong)(chong)電(dian)(dian)樁(zhuang)(zhuang)(zhuang)充(chong)(chong)電(dian)(dian)速度更快，工(gong)程(cheng)機(ji)械(xie)載重量大(da)、電(dian)(dian)池容量也大(da)，用(yong)交流充(chong)(chong)電(dian)(dian)樁(zhuang)(zhuang)(zhuang)的話(hua)充(chong)(chong)電(dian)(dian)速度慢，會耽誤工(gong)程(cheng)進度，因此工(gong)程(cheng)機(ji)械(xie)充(chong)(chong)電(dian)(dian)樁(zhuang)(zhuang)(zhuang)普遍都(dou)是大(da)功率直(zhi)流充(chong)(chong)電(dian)(dian)樁(zhuang)(zhuang)(zhuang)。

二、工程機械充電樁是單相電還是三相電

三相電。

工(gong)程機械充(chong)(chong)電(dian)(dian)樁(zhuang)(zhuang)是(shi)大功率直流充(chong)(chong)電(dian)(dian)樁(zhuang)(zhuang)，用(yong)單相(xiang)電(dian)(dian)的(de)(de)話帶不動，因為功率太(tai)大了，一般常見的(de)(de)工(gong)程機械充(chong)(chong)電(dian)(dian)樁(zhuang)(zhuang)是(shi)采用(yong)的(de)(de)三相(xiang)四線制供(gong)電(dian)(dian)，可以(yi)提供(gong)足(zu)夠(gou)的(de)(de)功率，輸出的(de)(de)電(dian)(dian)壓(ya)和電(dian)(dian)流調整范圍大，從而滿足(zu)為工(gong)程機械快速充(chong)(chong)電(dian)(dian)的(de)(de)要求。

三、工程機械充電樁是220v還是380v

380V。

充電(dian)(dian)樁(zhuang)有220V和380V兩種，一般220V主(zhu)要是(shi)(shi)普(pu)通家用新能(neng)源汽(qi)車使用，充電(dian)(dian)速(su)度較慢；工程機(ji)械充電(dian)(dian)樁(zhuang)是(shi)(shi)直流(liu)快充，電(dian)(dian)壓為380V。
