該大功(gong)(gong)率智(zhi)能充電機(ji)具(ju)有恒壓限(xian)流、恒流限(xian)壓、智(zhi)能充電、放(fang)電等控制模(mo)式。根據充電機(ji)需要具(ju)備的功(gong)(gong)能,確(que)定軟(ruan)件需要實(shi)現(xian)的功(gong)(gong)能,編制流程圖和(he)代(dai)碼。 
· 恒(heng)壓限流充電(dian)模式(shi) 
采用恒壓限流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)方式(shi)(shi),由(you)于開始(shi)時蓄(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)壓低,若(ruo)以大(da)電(dian)(dian)(dian)(dian)流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian),有損電(dian)(dian)(dian)(dian)池(chi)(chi)壽命,因此可以先采取恒流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)方式(shi)(shi),軟件設定(ding)(ding)(ding)初始(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu),例如15A,在恒定(ding)(ding)(ding)電(dian)(dian)(dian)(dian)流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)方式(shi)(shi)下,充(chong)(chong)到輸出(chu)電(dian)(dian)(dian)(dian)壓達到設定(ding)(ding)(ding)的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)組端電(dian)(dian)(dian)(dian)壓值(zhi)。然后,輸出(chu)電(dian)(dian)(dian)(dian)壓維(wei)持(chi)恒定(ding)(ding)(ding)不變(bian),隨(sui)著(zhu)充(chong)(chong)電(dian)(dian)(dian)(dian)進行,充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)逐漸減(jian)小,當充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)下降到程序設定(ding)(ding)(ding)的(de)較小的(de)數值(zhi)時,例如2A,充(chong)(chong)電(dian)(dian)(dian)(dian)機維(wei)持(chi)這(zhe)個設定(ding)(ding)(ding)的(de)小電(dian)(dian)(dian)(dian)流(liu)(liu)進行恒定(ding)(ding)(ding)電(dian)(dian)(dian)(dian)流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian),即為涓流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian),以此實現(xian)無人值(zhi)守(shou)。 
· 恒(heng)流自動充電 
采(cai)用恒流(liu)限壓(ya)(ya)方(fang)式(shi),需要人工設定(ding)充電(dian)電(dian)流(liu)和限定(ding)電(dian)壓(ya)(ya)。充電(dian)機以恒定(ding)電(dian)流(liu)充電(dian),電(dian)池組端電(dian)壓(ya)(ya)達到限定(ding)電(dian)壓(ya)(ya)時充電(dian)結束,可以無(wu)人值守。 
恒(heng)流(liu)(liu)限時實現方(fang)式為:人(ren)工設(she)定分(fen)段恒(heng)流(liu)(liu)充電(dian)(dian)的電(dian)(dian)流(liu)(liu)和時間(jian),程序設(she)定電(dian)(dian)流(liu)(liu)轉換的時刻,自動轉接(jie)到下一步(bu)低檔(dang)充電(dian)(dian)電(dian)(dian)流(liu)(liu),充電(dian)(dian)終止的判據為設(she)定的總體時間(jian)。 
· 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。上海施能(neng)電(dian)器(qi)設(she)備有限公(gong)司始建于(yu)1984年(nian),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。
