| Dynamic wireless charging technology for electric vehicles can effectively enhance convenience and safety,enabling "c harging on the go " to alleviate range anxiety and reduce dependence on fossil fuels,while aligning with green transportation requirements.Although numerous studies have been conducted on this technology,little research has been devoted to cost calculations and economic feasibility.This project proposes the application of dynamic wireless charging technology on highways,calculating costs and analyzing the economic feasibility of the Guizhou-Xinzhai highway as a case study.Firstly,a dynamic wireless charging highway project is proposed,which combines the technology with China’s highway de velopment and current situation to design a highway traffic operation mode.A detailed study of dynamic wireless charging highways is conducted based on the principles,and the layout plan for charging lanes on highways is investigated according to their transportation characteristics.Secondly,the national economic cost calculation is conducted for the proposed project.The project’s cost analysis considers material costs,construction costs,maintenance costs,and electricity costs.Material costs are calculated based on magnetic field strength principles for power ranges from 50 to 200 k W,air gap ranges from 100 to 300 mm,and magnetic core thickness ranges from 5 to 15 mm.The magnetic core thicknesses for different power levels are simulated and verified using ANSYS-MAXWELL software.The direct cost of the dynamic wireless charging highway project is estimated to be 3.6 to 6million yuan per kilometer.Lastly,based on the cost calculations,a national economic evaluation of the project is conducted.The e valuation benefits include reduced transportation costs for drivers,increased highway profits,and decreased carbon emissions.Using the Guizhou-Xinzhai highway as an example,the study examines the economic evaluation and sensitivity analysis at the project’s lowest and highest costs.The results show that the average transportation cost decreases by 8.1% to 48.75%,with benefits of 4.375 to 29.475 million yuan.With a revenue coefficient λ of 0.8,highway profits increase by 14.6 to 101.82 million yuan.Each truck can achie ve an annual reduction of 92 tons of CO2 emissions.The project’s payback period ranges from 5.25 to 8.23 years,with a net present value of175,053.98 to 237,543.98 million yuan,a benefit-cost ratio of 2.05 to 2.24,and an internal rate of return of 16.73% to 25.01%.The national economic eval uation indicators and sensitivity analysis meet the requirements,demonstrating the project’s considerable economic benefits and risk resilience. |
