在此非常感謝兄弟不厭其煩的指導.但小弟還是有些不明之處,望大俠指教,普通鉛酸充電器一般有三個階段,恒流、恒壓和浮充,如上大俠所說,是不是從恒流直接轉為恒壓和浮充,恒壓和浮充同時進行.以下是國外公司做的充電器規格書,它是先從恒流,再到恒壓充一段時間再轉到浮充狀態.望大俠指點.*CCmode=Constantcurrentcharge**Itispossibletoadjustthesevoltages(factoryset-up)***SeeStage3descriptionbelowStage1:DeepDischargeChargingPulseMode:LEDFlashThechargerstartschargingat0.5Vandgivepulsecurrentupto5V.Thishaseffectofremovingloosesulphationformedduringdeepdischargestateofthebattery.Stage2:ConstantCurrentMode(CC):LEDOrangeThechargerchangestoconstantcurrent1.5A.Whenthebatteryvoltagereachesupto28.8V,thechargingstagechangesfromCC(ConstantCurrent)toCV(ConstantVoltage)mode.Stage3:ConstantVoltageMode(CV):LEDGreen Thechargerholdsthebatteryat28.8Vandthecurrentslowlyreduces.Whenthecurrentreachesat0.10CC(CC=ConstantCurrent),thispointcalledtheSwitchingPoint.TheSwitchingPointisoneofthegreatfeatureofthisbatterychargerthatitcanadjustthecurrentautomaticallyaccordingtobatterycapacity.Otherchargersarenotcapabletoadjustthecurrentautomatically.
