In order to deeply study the automatic and intelligent method of smart electric power supply, this paper explores the application of wireless power transmission(WPT) in the field of driverless electric vehicles. This paper first introduces the charging principles of the 2 wireless charging modes, and then designs the corresponding charging systems respectively. Combined with the simulation, the comparison and analysis of the single receiving coil and the multi-receiving coil are carried out. It is concluded that the double receiving coil has a better power inhibition effect on the dynamic wireless charging of electric vehicles, and the appropriate coil size and spatial distribution are given. Then combined with the engineering application, this paper puts forward the active position detection strategy of electric vehicles and the collaborative wireless charging scheme combining static and dynamic charging modes. Finally, the practical application of radio energy transmission technology in the field of intelligent driverless electric vehicles is introduced.
