Design of an Embedded Charging Pile Electromagnetic Coupler Based on RFID

The embedded charging pile electromagnetic coupler is an important component to realize intelligent control and transmission of the induction power of the charging pile;it is also the key to the design of the charging pile.The stability of electric energy input and output of the charging pile is raised through design of optimal control for the electro-magnetic coupler.This paper presents design methods for the embedded charging pile electromagnetic coupler based on RFIDtechnology,analyzes the charging principle of the embedded charging pile,and describes overall design of the system.Topological structure of the embedded charging pile electromagnetic coupler is built up on the basis of the flat plate type electromagnetic coupler.Design of the integrated circuit for the embedded charging pile electromagnetic coupler is completed on the basis of RFID.Self-adaptive weighted coupling control is adopted to achieve optimal control of constraint parameters of the embedded charging pile electromagnetic coupling and improve output performance.Experimental results show that this system has a good intelligent charging control and a high charging efficiency for electric vehicles,thus improving power transmission efficiency of the intelligent charging pile.
