Abstract This study proposes a receiving pad identification coil for wireless charging of electric vehicles. The proposed
coil identifies the shape of the receiving pad through magnetic coupling with the receiving pad. Therefore, the
shape of the coil is designed to show the different magnetic properties of each receiving pad. The accuracy of
this design is verified through finite element method simulation. Furthermore, the operation method of the
secondary pad identification circuit is described, and the appropriate magnitude and length of the pulse voltage
applied to this circuit for receiving pad identification are derived through simulation. The performance of the
proposed identification coil set is verified by the experimental results.
