Abstract

Conductive charging of electric vehicles has entered a stable stage, and various product lines have been developed and standards have been made. Inductive charging methods can be classified into various other methods such as Indirect Power Transfer, Coupled Magnetic Resonance, and Permanent Magnet Coupled Transfer. Since choosing the most effective charging method for electric vehicles is difficult, standardizing the method of wirelessly transferring power is still a challenge to be achieved in a future. SAE J2954 sets an overall standard of electric vehicle Wireless Power Transport system. This paper proposes a wireless charging module that installs two receiving coils at a certain distance under the vehicle to minimize coil alignment due to incorrect parking and other vehicle full length during static charging. Finally, we developed an ATmega128 MCU-based module prototype and tested it to verify the efficiency of lower misalignment probability in different alignment charging environments compared to conventional single VA coils.
