基于ARM的均衡充电控制系统 英文论文：BalancedChargingControlSystemBasedonARM Introduction Withtheincreasingpopularityofelectricvehicles,thereisanurgentneedtodevelopabatterymanagementsystemthatcanefficientlyandsafelychargemultiplebatteries.Toaddressthisissue,thispaperproposesabalancedchargingcontrolsystembasedonARM.Thissystemisdesignedtoensurethateachbatteryischargeduniformly,whichcaneffectivelyextendbatterylifeandimprovethereliabilityofelectricvehicles. Background Inelectricvehicleapplications,batterypackbalanceiscriticaltotheoverallperformanceandlifeofthebatterypack.Imbalancedbatteriescancauseseveredamagetothepack,reduceenergycapacity,andleadtoprematureaging.Therefore,thebalancingofbatterycellsisessentialtoensurethelongevityoftheelectricvehiclesystem. Currently,thereareseveralbalancingtechnologiessuchaspassivebalancingwithresistors,activebalancingwithtransformers,andsemi-activebalancingthatcombinesthetwo.However,thesetechnologieshavevariouslimitations,includinghighpowerconsumption,lowconversionefficiency,andlargesize.Therefore,abettersystemisneededthataddressesthesechallenges.
