【Abstract】With the global energy transitionand the promotion of the "dual carbon"strategy，the optimizationof electricvehiclecharging technology has becomeoneof thecoreisues in thedevelopment of thenew energy vehicle industry.This paper proposesahardwarecontrolarchitecturebasedonavoltage divider circuit，multi-stagecomparator， and RSflip-floptoaddress thehighcomplexityand highcostof traditionalcharging systems thatrelyonmicrocontrolers and power managementchips.Theaim is toachieveenergybalanceandstabilityduring thecharging process.Through the dynamicthreshold adjustment mechanismand fault-tolerant design of bistable triggers，the system can complete multilevel voltage detectionand charging mode switching without software dependency，reducing hardware costsby more than （204号 50% .Experimental verification shows thatthe design meets the designrequirements in terms of voltage divisionaccuracy （20 （±1%） ，comparatorresponse time（<1ms），andanti-interference ability，providing technical support forthe popularization and safety improvement of charging infrastructure.
