| Abstract: | Electrified Road (e-Road), which is mainly characterized by Inductive Power Transfer (IPT), has been developing rapidly in recent years. It can provide dynamic wireless charging for moving electric vehicles, effectively solving the problems of long charging time and insufficient range of electric vehicles, and is an important reserve technology to support the development of electrification of road transportation.This review details the operating principles and performance characteristics of the IPT system and summarizes the charging performance parameters and TRL of existing e-Road test sections.On this basis, the main engineering problems and related research progress of e-Road are further analyzed from the perspective of infrastructure, including: ① an in-depth analysis of the impact of electromagnetic loss caused by high-frequency magnetic field through dielectric pavement materials on the charging efficiency of the IPT system and possible solutions; ② in view of the mechanical incompatibility between charging unit and asphalt pavement, the causes of the mechanical damage to the e-Road composite structure are inquired and potential optimization measures are proposed; ③ the life-cycle environmental performance of e-Road and conventional roads were assessed and compared, from which the environmental performance of e-Road is important and should be included in the full life-cycle sustainability framework for assessing the benefit of using electric vehicles.In addition, a comprehensive feasibility analysis of e-Road is conducted,in terms of policy support, safety, and price factors. An outlook is made on the future development of charging road infrastructure, including discussions over possible means to integrate e-Road with other new smart road technologies. |
