Abstract
Dynamic wireless power transfer (DWPT) systems are becoming increasingly important for on-the-move electric vehicle (EV) charging solutions, to overcome range anxiety and compensate for the consumed energy while the EV is in motion. In this work, a DWPT EV charging system is proposed to be implemented on a straight road stretch such that it provides the moving EV with energy at a rate of 308 Wh/km. This rate is expected to compensate for the vehicle’s average energy consumption and allow for additional energy storage in the EV battery. The proposed charging system operates at an average power transfer efficiency that is higher than 90% and provides good lateral misalignment tolerance up to ±200 mm. Details of the proposed system’s design are presented in this paper, including EV specifications, inductive link and compensation network design and power electronic circuitry.

Electric Vehicle Charging SystemThe design of efficient wireless electric vehicle (EV) chargers is one of the most extensively addressed research topics in transportation electrification and intelligent transportation systems (ITS)
The block diagram of a typical inductive EV wireless charging system is shown in Figure 1, following the standardized stationary wireless EV chargers model presented in the Society of Automotive Engineers (SAE) J2954 Standard [6]
Once the inductive link design was finalized, finite element method (FEM) simulation results were exported into a circuit-level simulation on MATLAB/SIMULINK platform to simulate the operation of the compensation networks, the inverter and rectifier circuits and the EV battery together with the inductive link model
Summary
The design of efficient wireless electric vehicle (EV) chargers is one of the most extensively addressed research topics in transportation electrification and intelligent transportation systems (ITS). Several studies on the design of EV DWC systems are reported in the literature, addressing charging coils and compensation network designs, and the design of the electronic circuitry, aiming to improve the power transfer capability and misalignment tolerances of these on-road wireless chargers. In order to simultaneously address all three objectives, this work integrates the different strategies addressed in those studies, including LCC–LCC network tuning and dual-side control, with a robust inductive link design, to leverage their corresponding advantages in improving the misalignment tolerance while addressing the maximum power and maximum efficiency objectives of dynamic wireless EV charging systems and acknowledging the EV energy demands.
