該大功率智(zhi)(zhi)能(neng)(neng)充電(dian)機具有恒(heng)壓限(xian)流、恒(heng)流限(xian)壓、智(zhi)(zhi)能(neng)(neng)充電(dian)、放電(dian)等(deng)控(kong)制模式。根據充電(dian)機需要具備的功能(neng)(neng),確定軟件需要實現的功能(neng)(neng),編制流程(cheng)圖(tu)和(he)代(dai)碼。 
· 恒(heng)壓限流(liu)充電(dian)模式 
采用恒(heng)(heng)(heng)壓(ya)限流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)方式(shi),由于開始(shi)時蓄電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)壓(ya)低,若以大(da)電(dian)(dian)(dian)(dian)(dian)流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian),有損電(dian)(dian)(dian)(dian)(dian)池(chi)壽命,因此可以先采取恒(heng)(heng)(heng)流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)方式(shi),軟件設(she)定(ding)(ding)初始(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu),例(li)如15A,在(zai)恒(heng)(heng)(heng)定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)方式(shi)下(xia),充(chong)(chong)(chong)(chong)到(dao)輸出電(dian)(dian)(dian)(dian)(dian)壓(ya)達到(dao)設(she)定(ding)(ding)的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)組端電(dian)(dian)(dian)(dian)(dian)壓(ya)值。然后,輸出電(dian)(dian)(dian)(dian)(dian)壓(ya)維持恒(heng)(heng)(heng)定(ding)(ding)不變,隨(sui)著充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)進行(xing),充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)逐漸減小(xiao),當充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)下(xia)降到(dao)程序設(she)定(ding)(ding)的(de)較小(xiao)的(de)數(shu)值時,例(li)如2A,充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)機維持這個設(she)定(ding)(ding)的(de)小(xiao)電(dian)(dian)(dian)(dian)(dian)流(liu)進行(xing)恒(heng)(heng)(heng)定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian),即為涓流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian),以此實現(xian)無人值守。 
· 恒流自動充(chong)電(dian) 
采用恒(heng)流(liu)限(xian)(xian)壓(ya)方式,需要人工(gong)設定(ding)充電(dian)電(dian)流(liu)和(he)限(xian)(xian)定(ding)電(dian)壓(ya)。充電(dian)機以恒(heng)定(ding)電(dian)流(liu)充電(dian),電(dian)池組端電(dian)壓(ya)達(da)到限(xian)(xian)定(ding)電(dian)壓(ya)時充電(dian)結束,可以無人值守。 
恒(heng)流限時實現方式為:人工設(she)定分段恒(heng)流充電(dian)的(de)(de)電(dian)流和時間,程序設(she)定電(dian)流轉換的(de)(de)時刻,自動轉接到下一步低檔(dang)充電(dian)電(dian)流,充電(dian)終止的(de)(de)判據為設(she)定的(de)(de)總(zong)體時間。 
· 智能控制自動充電 
應用du/dt 和di/dt 技術,動態跟蹤電池可接受的充電電流。充電系統由充電機和電池組成二元閉環回路,充電機根據電池的狀態確定充電工藝參數,充電電流自始自終在電池的可接受充電電流曲線附近。上海施(shi)能電器設備有限公司(si)始建于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。
