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，那么(me)它是直流充電樁還是交(jiao)流充電樁呢？

據了解(jie)，一般工(gong)程機(ji)械充(chong)(chong)(chong)電(dian)樁都是直流充(chong)(chong)(chong)電(dian)樁，因為直流充(chong)(chong)(chong)電(dian)樁充(chong)(chong)(chong)電(dian)速度更(geng)快，工(gong)程機(ji)械載重量大、電(dian)池容量也(ye)大，用交流充(chong)(chong)(chong)電(dian)樁的話充(chong)(chong)(chong)電(dian)速度慢(man)，會(hui)耽誤(wu)工(gong)程進度，因此(ci)工(gong)程機(ji)械充(chong)(chong)(chong)電(dian)樁普遍(bian)都是大功率直流充(chong)(chong)(chong)電(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(ji)械充(chong)(chong)電(dian)(dian)樁(zhuang)是(shi)(shi)大(da)功率(lv)直(zhi)流(liu)充(chong)(chong)電(dian)(dian)樁(zhuang)，用單相電(dian)(dian)的話帶不動，因為功率(lv)太大(da)了，一般常見的工(gong)程機(ji)械充(chong)(chong)電(dian)(dian)樁(zhuang)是(shi)(shi)采用的三(san)相四(si)線(xian)制供(gong)電(dian)(dian)，可(ke)以提供(gong)足夠的功率(lv)，輸出的電(dian)(dian)壓和電(dian)(dian)流(liu)調整范圍大(da)，從而滿(man)足為工(gong)程機(ji)械快速充(chong)(chong)電(dian)(dian)的要求。

三、工程機械充電樁是220v還是380v

380V。

充(chong)電(dian)(dian)(dian)樁有(you)220V和380V兩種，一般(ban)220V主要(yao)是(shi)普通(tong)家用新能源汽車使用，充(chong)電(dian)(dian)(dian)速度較慢；工程(cheng)機械充(chong)電(dian)(dian)(dian)樁是(shi)直流(liu)快充(chong)，電(dian)(dian)(dian)壓為380V。
