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(dian)動工(gong)程機(ji)械(xie)充(chong)(chong)電(dian)的,那(nei)么它是直(zhi)流充(chong)(chong)電(dian)樁還是交流充(chong)(chong)電(dian)樁呢?
據了解,一般工(gong)程機械(xie)充電(dian)(dian)樁(zhuang)(zhuang)都(dou)是直(zhi)流(liu)充電(dian)(dian)樁(zhuang)(zhuang),因為直(zhi)流(liu)充電(dian)(dian)樁(zhuang)(zhuang)充電(dian)(dian)速(su)度(du)更(geng)快,工(gong)程機械(xie)載重(zhong)量大、電(dian)(dian)池容(rong)量也大,用交(jiao)流(liu)充電(dian)(dian)樁(zhuang)(zhuang)的話充電(dian)(dian)速(su)度(du)慢,會耽誤工(gong)程進(jin)度(du),因此(ci)工(gong)程機械(xie)充電(dian)(dian)樁(zhuang)(zhuang)普遍(bian)都(dou)是大功率直(zhi)流(liu)充電(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)程機械(xie)充(chong)電(dian)(dian)樁(zhuang)是大功率直流(liu)充(chong)電(dian)(dian)樁(zhuang),用單相電(dian)(dian)的(de)話帶不動,因為(wei)(wei)功率太(tai)大了(le),一般常見的(de)工(gong)程機械(xie)充(chong)電(dian)(dian)樁(zhuang)是采用的(de)三相四線制供電(dian)(dian),可以提供足(zu)夠(gou)的(de)功率,輸出的(de)電(dian)(dian)壓和電(dian)(dian)流(liu)調整范(fan)圍大,從而滿足(zu)為(wei)(wei)工(gong)程機械(xie)快速充(chong)電(dian)(dian)的(de)要求。
三、工程機械充電樁是220v還是380v
380V。
充電(dian)樁(zhuang)有220V和380V兩種,一般220V主要是(shi)普通家用新能源汽車(che)使用,充電(dian)速度(du)較慢;工程機(ji)械充電(dian)樁(zhuang)是(shi)直流快充,電(dian)壓為380V。
