Summary: As the number of electric vehicles (EV) increases, the assessment of electromagnetic field exposure from EV chargers becomes important. This study evaluated the electromagnetic field exposure of six EV chargers by measuring and analyzing their electromagnetic fields. The exposure levels were compared against ICNIRP guidelines and it was found that standard chargers emitted higher electromagnetic fields than fast chargers. However, all six chargers' electromagnetic field exposures were within standard limits. This assessment will contribute to establishing future standards for evaluating EV charger electromagnetic field exposure.

Summary: This article proposes a switching frequency-modulation-based inductive power transfer system that provides wireless charging for scooters through magnetic in-band communication. The proposed system allows for charging even when the transmitter and receiver coils are misaligned, without the need for additional power converters.

Summary: This article highlights the importance of topology optimization in designing ferrite plates for inductive power transfer systems in electric vehicles. The SIMP method is used to optimize the ferrite plates by modifying their topology iteratively. Results show that removing a part of the ferrite from the center and edges of the plate can save volume without significantly reducing transmission efficiency. Additionally, the presence of an aluminum shielding plate near the ferrite plate affects the optimization results, requiring a larger ferrite plate on the receiver side. These findings provide design guidelines for ferrite placement and can be extended to shielding sheets/walls.
