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)(dian)(dian)動工程機械充(chong)電(dian)(dian)(dian)的，那(nei)么它是直流充(chong)電(dian)(dian)(dian)樁(zhuang)還(huan)是交流充(chong)電(dian)(dian)(dian)樁(zhuang)呢(ni)？

據了解，一(yi)般工(gong)程(cheng)機械充(chong)電(dian)樁(zhuang)(zhuang)都是直(zhi)流充(chong)電(dian)樁(zhuang)(zhuang)，因為直(zhi)流充(chong)電(dian)樁(zhuang)(zhuang)充(chong)電(dian)速(su)度更快(kuai)，工(gong)程(cheng)機械載重量大(da)、電(dian)池(chi)容量也大(da)，用(yong)交流充(chong)電(dian)樁(zhuang)(zhuang)的話充(chong)電(dian)速(su)度慢，會耽誤工(gong)程(cheng)進度，因此(ci)工(gong)程(cheng)機械充(chong)電(dian)樁(zhuang)(zhuang)普遍都是大(da)功率直(zhi)流充(chong)電(dian)樁(zhuang)(zhuang)。

二、工程機械充電樁是單相電還是三相電

三相電。

工程(cheng)機械(xie)充電(dian)(dian)(dian)樁(zhuang)是大功(gong)率(lv)(lv)直流(liu)(liu)充電(dian)(dian)(dian)樁(zhuang)，用單(dan)相電(dian)(dian)(dian)的(de)(de)(de)話(hua)帶不動，因為(wei)功(gong)率(lv)(lv)太大了(le)，一般常(chang)見(jian)的(de)(de)(de)工程(cheng)機械(xie)充電(dian)(dian)(dian)樁(zhuang)是采(cai)用的(de)(de)(de)三相四線制供(gong)電(dian)(dian)(dian)，可以提(ti)供(gong)足夠的(de)(de)(de)功(gong)率(lv)(lv)，輸(shu)出(chu)的(de)(de)(de)電(dian)(dian)(dian)壓和電(dian)(dian)(dian)流(liu)(liu)調整范(fan)圍大，從而滿足為(wei)工程(cheng)機械(xie)快速充電(dian)(dian)(dian)的(de)(de)(de)要(yao)求。

三、工程機械充電樁是220v還是380v

380V。

充(chong)電(dian)(dian)(dian)樁(zhuang)有220V和380V兩(liang)種，一般(ban)220V主要是(shi)普通家用(yong)新能源汽車使用(yong)，充(chong)電(dian)(dian)(dian)速度較慢；工程(cheng)機械充(chong)電(dian)(dian)(dian)樁(zhuang)是(shi)直流快充(chong)，電(dian)(dian)(dian)壓為380V。
