傳統(tong)大功率充(chong)電(dian)(dian)(dian)(dian)(dian)機(ji)由于采用(yong)的(de)是變壓器變壓整(zheng)流(liu)、可控(kong)硅控(kong)制的(de)方(fang)法，因此設備笨重，可靠性(xing)差。電(dian)(dian)(dian)(dian)(dian)瓶充(chong)電(dian)(dian)(dian)(dian)(dian)機(ji)、汽車充(chong)電(dian)(dian)(dian)(dian)(dian)機(ji)、汽車電(dian)(dian)(dian)(dian)(dian)瓶充(chong)電(dian)(dian)(dian)(dian)(dian)機(ji)、電(dian)(dian)(dian)(dian)(dian)動(dong)汽車充(chong)電(dian)(dian)(dian)(dian)(dian)機(ji)、電(dian)(dian)(dian)(dian)(dian)動(dong)叉車充(chong)電(dian)(dian)(dian)(dian)(dian)機(ji)的(de)蓄電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)，共同面(mian)臨的(de)一(yi)大問(wen)題是這種小電(dian)(dian)(dian)(dian)(dian)流(liu)慢(man)充(chong)方(fang)式，蓄電(dian)(dian)(dian)(dian)(dian)池(chi)初充(chong)所需時間(jian)非(fei)常長，充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)遠小于蓄電(dian)(dian)(dian)(dian)(dian)池(chi)可接受(shou)的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)，不僅耗時長，且能源利用(yong)不充(chong)分。
為了提高大(da)功(gong)率充電機(ji)充電效(xiao)率，使(shi)運營成本降低，設計以大(da)功(gong)率IGBT為核心的智(zhi)能型全自動快速充電機(ji)勢在必(bi)行，這種技術還具(ju)有節能環(huan)保等諸方面的社會意義。
大功率充電機采用多個電源模塊并聯供電的方式來實現大功率的輸出。如果產生的諧波如果沒有被有效控制，將會污染電網。因此，大功率充電機中須采用并聯均流策略來平衡負載電流分配，實現了充電機低諧波高功率因素運行，改善了充電機并聯均流性能。上(shang)海施能電器(qi)設備有限公司始(shi)建于1984年，上海市高新技術企業，中國工業車輛優秀配套供應商，上海電器行業名優產品，主要生產工頻系列充電機，高頻系列充電機，鋰電池充電機，系列放電機，系列充放電機等電器產品。
