Magnetic Field Analysis of 50 kW Wireless Power Transfer System for Heavy Duty Vehicles

This scientific publication delves into the magnetic field characteristics of high-power wireless transfer systems in the context of two trucks parked side by side with potential misalignment. The study aims to reflect real-life scenarios encountered in parking lots or depots, where multiple trucks undergo simultaneous charging. For comprehensive investigations, we employ unipolar coil arrangements specifically designed for high-power transfer applications. The electromagnetic field analyses are performed using finite element analysis modeling. With an evaluation method developed based on standards, the results show that depending on the relative positioning of the considered trucks, measures to guarantee electromagnetic field safety-level compliance might become necessary.
