Experimental Implementation of a Wireless Communication System for Electric Vehicle WPT Charger

Abstract

Electric Vehicle (EV) market is growing rapidly and the demand for new charging methods is up surging. In order to meet this growing demand, wireless power transmission is a good choice for providing energy because it has many advantages such as convenience, user-friendliness and safety. Such charging method requires a wireless communication between EVs and electric vehicle supply equipment (EVSE) to ensure that power is transferred in a precisely controlled way. This paper proposes a wireless communication system based on Raspberry Pi 4 and TMS320F28335 development kit from Texas Instruments. It consists in acquisition and wireless transmission of analogue data from a client to a server. The system is experimentally verified and the obtained result shows that the system provides a good performance for a range of frequencies. Thus, the proposed solution presents a good basis for the next step of controlling wireless power transmission.
