【Abstract】This paper focuses on the optimal design and energy-saving benefits of the thermal management system for newenergyvehicles.Aiming atthedeficienciesofthe existing system inenergyconsumption control，temperature uniformityand inteligent regulation，amulti-lop integrationand heat pumpcompositescheme isproposed.Combined with newmaterials such as phasechange materialsand nano-fluids，thestructure ofheat exchange elements and control strategies are optimized.Multi-condition simulations were cariedoutusing AMESim，GT-SUITEand Simulink platforms toestablishanenergy-saving benefitevaluationmodelandquantitativelyanalyzetheefectsofenergyconsumption reduction，batery life extension and driving range improvementbeforeand after systemoptimization.Theresults show thattheoptimizeddesignsignificantlyimprovesthethermaleficiency，reducestheenergyconsumptionof thermal management，delaysbatterydegradation，andenhances thevehicle'sdriving range.Theresearch provides theoretical basisandtechnicalsupportfortheeficientintegrationandintellgentcontrolof thethermal managementsystemof new energyvehicles，and hasimportant applicationvalueandpromotion prospects.Future work willfocuson further enhancing the inteligent level of thesystem anddevelopingadaptive control strategies to adapttocomplex working conditions.
