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)專門(men)給電(dian)動工程機械充電(dian)的，那么它是(shi)直流充電(dian)樁(zhuang)還(huan)是(shi)交流充電(dian)樁(zhuang)呢？

據了解，一般工(gong)程(cheng)機械(xie)充(chong)電(dian)(dian)(dian)樁都是直(zhi)流充(chong)電(dian)(dian)(dian)樁，因為直(zhi)流充(chong)電(dian)(dian)(dian)樁充(chong)電(dian)(dian)(dian)速度(du)更快，工(gong)程(cheng)機械(xie)載(zai)重量(liang)大、電(dian)(dian)(dian)池容量(liang)也大，用(yong)交流充(chong)電(dian)(dian)(dian)樁的話充(chong)電(dian)(dian)(dian)速度(du)慢(man)，會耽誤工(gong)程(cheng)進度(du)，因此工(gong)程(cheng)機械(xie)充(chong)電(dian)(dian)(dian)樁普遍都是大功(gong)率直(zhi)流充(chong)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。

工程(cheng)(cheng)機(ji)械充(chong)(chong)(chong)電(dian)(dian)樁(zhuang)是(shi)大功率(lv)直(zhi)流充(chong)(chong)(chong)電(dian)(dian)樁(zhuang)，用單相電(dian)(dian)的(de)(de)話帶不動(dong)，因為功率(lv)太大了，一般常見的(de)(de)工程(cheng)(cheng)機(ji)械充(chong)(chong)(chong)電(dian)(dian)樁(zhuang)是(shi)采用的(de)(de)三相四線制供電(dian)(dian)，可以提供足夠的(de)(de)功率(lv)，輸(shu)出的(de)(de)電(dian)(dian)壓和電(dian)(dian)流調整范圍大，從而滿足為工程(cheng)(cheng)機(ji)械快速充(chong)(chong)(chong)電(dian)(dian)的(de)(de)要(yao)求(qiu)。

三、工程機械充電樁是220v還是380v

380V。

充(chong)(chong)電樁有(you)220V和380V兩(liang)種，一般220V主要(yao)是普通家用(yong)新能源汽車使用(yong)，充(chong)(chong)電速(su)度較慢；工程機械充(chong)(chong)電樁是直流快充(chong)(chong)，電壓為(wei)380V。
