An Inductive Power Transfer System for Electric Vehicle Battery Charging
|
The inductive power transfer (IPT) is a technology enabling power transfer between two
mutually-coupled inductors across a large air gap. Among the applications of IPT is the
contactless charging of electric vehicles.
The IPT system controllers are represented
by two distinct circular pads. Each pad is composed of a Litz wire coil and 12 ferrite
strips. At constant AC frequency, the airgap dimension between the circular pads is function
of the flux resulting from the AC current crossing the primary circular pad. The objective
of this study is to compute the primary pad inductance in function of the airgap between the
two pads in order to determine how to maximize magnetic flux at constant frequency.

Can We Print a 5G Antenna on a Car’s Window Glass?
|
|
In recent years, vehicle communication systems have bourgeoned, especially in
Vehicle-to-vehicle (V2V) communication. This paradigm shift can be attributed to
the strong appeal to minimize roadway collisions which are responsible for the
death of some 1.35 million persons every year around the world. V2V
communication needs 5G antennas to maintain stable link whilst driving in a
changing environment; and that poses an enormous engineering undertaking. To
avoid modifying the vehicle structure or adding new structure to the vehicle, 5G
engineers have no choice but print the communication antennas on the vehicle
window’s glass.
