Overview

Simulation and experimental study demonstrates enhanced magnetic coupling and 96.23% transfer efficiency in wireless electric vehicle charging systems, indicating robust tolerance to misalignment.

Key Points

Design and evaluate an optimized multilayer rectangular coil to mitigate efficiency losses caused by spatial and angular misalignment in wireless electric vehicle charging systems.
Conducted 3D finite element analysis in Ansys Maxwell to model electromagnetic coupling and compare the multilayer rectangular coil against circular, rectangular, and DD coil configurations.
Simulated a 3.3 kW power transfer setup using an LCC-Series compensation network in PSIM across varying air gaps (160–200 mm) and misalignment angles (up to 20°).
Constructed and tested a 120 W experimental laboratory prototype operating at 36 V DC input and a 22 kHz inverter frequency to validate mutual inductance and misalignment behavior.
The multilayer rectangular coil achieved a 32.63% higher coupling coefficient than circular coils at a 200 mm air gap and an 87.24% improvement under lateral misalignment.
The simulated system delivered 3.3 kW at a 160 mm air gap and achieved 96.23% DC-to-DC efficiency at 22 kHz, retaining transfer performance across 300 mm lateral and 20° angular displacements.
Experimental tests on the 120 W prototype confirmed theoretical models, demonstrating sustained coupling coefficients and mutual inductance under displaced positions.
