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(zhuan)門給電動(dong)工(gong)程機械充電的，那(nei)么它是直流充電樁還是交流充電樁呢？

據(ju)了(le)解，一般(ban)工(gong)程機械充電(dian)(dian)(dian)樁都是(shi)直(zhi)流充電(dian)(dian)(dian)樁，因為直(zhi)流充電(dian)(dian)(dian)樁充電(dian)(dian)(dian)速(su)度(du)更(geng)快，工(gong)程機械載(zai)重量(liang)大、電(dian)(dian)(dian)池容量(liang)也大，用交流充電(dian)(dian)(dian)樁的話充電(dian)(dian)(dian)速(su)度(du)慢(man)，會耽誤工(gong)程進度(du)，因此工(gong)程機械充電(dian)(dian)(dian)樁普遍都是(shi)大功率直(zhi)流充電(dian)(dian)(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)械充電(dian)(dian)(dian)樁是大功(gong)率直流充電(dian)(dian)(dian)樁，用單相(xiang)電(dian)(dian)(dian)的話帶不動，因為功(gong)率太(tai)大了(le)，一(yi)般常見的工(gong)程機(ji)械充電(dian)(dian)(dian)樁是采用的三(san)相(xiang)四線制(zhi)供(gong)(gong)電(dian)(dian)(dian)，可(ke)以提供(gong)(gong)足夠的功(gong)率，輸出的電(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)流調整范圍大，從(cong)而滿足為工(gong)程機(ji)械快(kuai)速(su)充電(dian)(dian)(dian)的要求。

三、工程機械充電樁是220v還是380v

380V。

充(chong)電樁有220V和380V兩種，一般220V主要是(shi)(shi)普通(tong)家(jia)用新能源(yuan)汽車使用，充(chong)電速度較慢(man)；工程機械充(chong)電樁是(shi)(shi)直流快充(chong)，電壓(ya)為380V。
