謝謝您的無私奉獻,我們都要向您學習!

可否說明?恒流何時轉恒壓充電?是依据檢測那項參數進行轉換的?

電池的損坏還與放電有關充電注意事項各位已講過.可是電池損坏不但與過充有關還與過渡放電有關,不知電池是否有低電保護.

用LM317可實現恒流1063681456.pdf

可能有一點用

是否與PCB  LAYOUT有關輸入濾波電容﹐輸出濾波電容需要單點接地﹒連接輸入濾波電容器高頻變壓器銅泊面積盡量小﹒嘗試用1ouncePCBlayout.Layout時盡量做到線條流暢﹒不周之處請各位指正﹐謝謝﹗﹗

這是負電壓斜率檢測型快速充電器這种電路有兩部分組成﹒一部分為大電流脈沖充放電去极化充電電路﹒另一部分為負電壓斜率檢測電路﹒充電前﹐對電池現存電量進行檢測﹒若電量不足﹐則在充電時啟動定時器並將其置零﹒定時期間關閉負電壓斜率檢測電路﹐這樣可使大容量電池定時延長﹒充電過程中預設一電壓﹐電池端電壓低于此值﹐負電壓斜率檢測同時關閉﹒停止充電后﹐繼續對電池端電壓進行檢測﹐並以此判斷電池是否欠充﹐若是重新啟動充電器﹒此電路优點1)避免了“雙峰效應“2)對內阻較大的舊電池進行保護﹐同時通過內阻檢測利用施密特触發器對定時可實施禁止3)脈沖  沖充放電去极化﹐消除“記憶效應“對廢舊或故障電池有恢复和修复作用﹒4)最突出的优點成本低﹐監控嚴密﹒不足之處請大家指正﹐謝謝﹗﹗
