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(men)給電(dian)動工(gong)程機(ji)械(xie)充(chong)電(dian)的(de)，那么它是直流充(chong)電(dian)樁還是交流充(chong)電(dian)樁呢？

據了(le)解，一般(ban)工(gong)(gong)(gong)程機(ji)械(xie)(xie)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)(zhuang)都(dou)(dou)是(shi)直流(liu)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)(zhuang)，因為(wei)直流(liu)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)(zhuang)充(chong)(chong)電(dian)(dian)(dian)速度更快(kuai)，工(gong)(gong)(gong)程機(ji)械(xie)(xie)載重量大、電(dian)(dian)(dian)池容量也大，用交流(liu)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)(zhuang)的話充(chong)(chong)電(dian)(dian)(dian)速度慢，會(hui)耽誤工(gong)(gong)(gong)程進度，因此工(gong)(gong)(gong)程機(ji)械(xie)(xie)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)(zhuang)普遍都(dou)(dou)是(shi)大功率直流(liu)充(chong)(chong)電(dian)(dian)(dian)樁(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(cheng)機械(xie)充電樁是大(da)(da)功率直流充電樁，用單(dan)相(xiang)電的(de)話帶(dai)不動，因為功率太大(da)(da)了，一(yi)般(ban)常見的(de)工(gong)程(cheng)機械(xie)充電樁是采用的(de)三相(xiang)四線制供電，可以(yi)提(ti)供足(zu)(zu)夠的(de)功率，輸出的(de)電壓(ya)和電流調整(zheng)范圍(wei)大(da)(da)，從(cong)而滿足(zu)(zu)為工(gong)程(cheng)機械(xie)快(kuai)速充電的(de)要求(qiu)。

三、工程機械充電樁是220v還是380v

380V。

充電(dian)(dian)樁有220V和380V兩種，一般220V主要是(shi)普通家用(yong)新(xin)能源汽車使用(yong)，充電(dian)(dian)速(su)度較慢；工程機械充電(dian)(dian)樁是(shi)直流快充，電(dian)(dian)壓為380V。
