As　more　electric　vehicles　(EV)　companies　jump　on　the　bandwagon　of　wireless　power　transmission,　interoperability　issues　are　becoming　increasingly　apparent.　In　addition　to　the　common　problems　of　coupling　structure,　compensation　network　and　communication　protocol　interoperability,　battery　voltage　(BV)　interoperability　issues　are　also　gradually　emerging,　that　is,　different　battery　voltage　levels　of　various　models.　For　the　BV　level　of　the　existing　EV　power　battery,　the　rated　voltage　can　be　mainly　divided　into　400　and　800　V.　Considering　the　interoperability　of　public　radio　energy　transmission　facilities,　EV　radio　energy　transmission　systems　must　be　effectively　compatible　with　400　and　800　V　BV　levels　at　the　same　power　level.　A　reconfigurable　topology　with　the　BV　interoperability　is　proposed.　The　device　uses　two　completely　stacked　unipolar　coils　as　magnetic　coupling　structures,　enabling　two　different　output　voltages　under　the　same　power　level　by　switching.　The　proposed　system　is　analyzed　and　modeled　by　establishing　a　mathematical　model,　followed　by　the　development　of　a　1.　3　kW　downscaled　experimental　prototype　to　verify　the　function　of　the　proposed　reconfigurable　topology.　The　results　show　that　the　system　can　switch　between　200　and　400　V　output　voltages　while　maintaining　an　output　power　of　1.　3　kW.　The　maximum　system　direct　current　-　direct　current　(DC-DC)　efficiency　is　90.　97%　and　95.　51%,　respectively.　Finally,　to　assess　the　migration　performance　of　the　proposed　structure,　additional　testing　was　conducted　using　the　experimental　prototype.　The　results　show　that　the　DC-DC　efficiency　of　the　proposed　system　is　higher　than　90%　in　the　migration　range　of　±100　mm.　©　2025　Science　Press.　All　rights　reserved.
