Abstract

Evaluation of Electromagnetic Exposure During 85 kHz Wireless Power Transfer for Electric Vehicles SangWook Park. Evaluation of Electromagnetic Exposure During 85 kHz Wireless Power Transfer for Electric Vehicles. IEEE Transactions on Magnetics. Volume: PP, Issue: 99. Sep 1, 2017. 10.1109/TMAG.2017.2748498 Abstract The external fields in the proximity of electric vehicle (EV) wireless power transfer (WPT) systems requiring high power may exceed the limits of international safety guidelines. This study presents dosimetric results of an 85 kHz WPT system for electric vehicles. A WPT system for charging EVs is designed and dosimetry for the system is evaluated for various exposure scenarios: a human body in front of the WPT system without shielding, with shielding, with alignment and misalignment between transmitter and receiver, and with a metal plate on the system for vehicle mimic floor pan. The minimum accessible distances in compliance are investigated for various transmitting powers. The maximum allowable transmitting power are also investigated with the limits of international safety guidelines and the dosimetric results. ieeexplore.ieee.org

Main findings

The study reports dosimetric evaluation of an 85 kHz EV wireless power transfer system across multiple exposure scenarios (e.g., shielding vs no shielding, alignment vs misalignment, and presence of a metal plate) and investigates minimum accessible distances and maximum allowable transmitting power for compliance with international safety guideline limits.

Outcomes measured

dosimetric results
compliance with international safety guidelines
minimum accessible distance for compliance
maximum allowable transmitting power under guideline limits

Suggested hubs

occupational-exposure (0.2)
Exposure scenarios near high-power EV wireless power transfer systems may be relevant to workplace/operational settings, though the abstract does not specify workers.
