A Secured Wireless Charging Scheme with Data Transmission

Abstract

This research task proposes a magnetic resonant coupling wireless power transfer (MRC-WPT) scheme for electric vehicles, which realizes secure data communication between the wireless charging station and the electric vehicle using binary phase shift-keying (BPSK) data transmission, thereby waving any radio frequency (RF) communication links. The secondary side is designed to accept power while transmits data back to the primary side simultaneously. The BPSK design ensures data transmission robustness to against disturbance interference. The data is encrypted by the user's biometric features for information security. The magnetic resonance performs better than that of the traditional magnetic induction in the power transmission efficiency against coil misalignments. With the Internet of Thing (IoT) architecture, the encrypted data can be stored and retrieved via the cloud server.
