Interoperability of Electric Vehicle Wireless Charging System Based on Decoupled Four-monopole Receiving Coil
In recent years,electric vehicles have developed rapidly,but the traditional wired charging method cannot meet the requirements of automation and convenience of the vehicles.Therefore,the wireless charging technology for electric vehicles has been widely studied for its safety and convenience.The common coil structures in the wireless charging system include the unipolar coil,the bipolar coil and the quadrupole coil.Due to the adaptation problems of different manufacturers,a new type of coil should be designed to get compatible with these coils to achieve the interoperability.This paper presents a new decoupled quadruple monopole receiving coil structure,which may achieve the interoperability with different transmitting coils.The decoupling between the four receiving coils is realized by adding a decoupling winding inside the receiving coils.Then,the total mutual inductance between the transmitting coil and the four monopole receiving coils is the sum of the absolute value of the mutual inductance between the transmitting coil and the four monopole coils by the series diode rectifier.A set of experimental prototype is built to verify the effectiveness of the scheme.The proposed four-monopole receiving coil is able to be compatible with the unipolar coil,the bipolar coil and the quadrupole coil,realizing the interoperability with different receiving coils.
