摘要

Abstract

Long-distance highway travel imposes more stringent requirements on the energy replenishment efficiency of electric vehicles. The currently dominant stationary fast-charging mode remains constrained by limited service-area space

queuing time

and peak charging loads. Dynamic wireless charging embeds the energy replenishment process into vehicle motion and thus provides a new design pathway for highway electrification infrastructure. Focusing on this scenario

this paper analyzes two key issues: the layout of roadside transmitting coils and multi-vehicle power scheduling. On the coil side

the effects of vehicle speed

lateral offset

and vertical air gap on the coupling coefficient and output power are examined based on the principle of magnetic-resonant wireless power transfer. The engineering applicability of long-coil

segmented-coil

and modular-coil structures is then compared. On the control side

a multi-vehicle power allocation model under vehicle-road collaboration is established

and a genetic algorithm and an improved particle swarm optimization algorithm are adopted to optimize coil parameters and real-time power scheduling

respectively. Co-simulation and scaled experimental results show that the proposed 1.5 m segmented overlapping coil achieves a coupling efficiency of 92.2% and limits output-power fluctuation to within +/-4.8%. When ten vehicles are charged in parallel

the grid-capacity utilization reaches 98.5%

and total energy consumption decreases by 8.5% compared with the baseline scheme. The results indicate that coordinated design of coil layout and power scheduling can improve the stability and deployability of highway dynamic wireless charging systems.
