Abstract

This disclosure relates to a wireless charging road and a wireless charging vehicle. The wireless charging road includes a road basement, a road surface layer located on the road basement, and a magnetic field generator. The magnetic field generator generates magnetic force lines above the road surface layer. The wireless charging vehicle includes a vehicle body, and a charging device located on the vehicle body. The charging device includes an induction wire and a rechargeable battery. Two ends of the induction wire are respectively connected to the positive pole and the negative pole of the rechargeable battery. The induction wire cuts the magnetic force lines to produce an electric potential and charges the rechargeable battery when the wireless charging vehicle drives on the wireless charging road.
