Implementation of WPT communication system based on SAE J2847 standard for electric vehicle

In this paper, we examined the necessity of a proper communication protocol in WPT and studied the structure of communication protocol based on SAE J2847 standard. Then, we implemented an integrated wireless charging system using SAE J2847-6 based WPT communication and confirmed its normal operation through experiments. In order to communicate, we proposed CAN data format and used it as the interface between EVCC and regulator. With this structure, normal operation was verified using the corresponding format. In addition, since the standard focuses on a single charge, a communication structure suitable for a multi-charge situation is proposed.
