Abstract:
A power supply device which supplies power to an electric vehicle in a magnetic induction method, includes a plurality of power supply core units. Each of the power supply core units has a plurality of magnetic poles arranged at a predetermined distance from each other along a traveling direction of a road and has a width equal to or less than 1/2 of the distance between the magnetic poles in a direction perpendicular to the traveling direction of the electric vehicle on the road. Further, the power supply device includes a plurality of power supply lines arranged along the traveling direction of the electric vehicle on the road such that the magnetic poles of the adjacent power supply core units have different polarities.
Abstract:
A power supply and acquisition apparatus for an electrical vehicle includes a power supply device embedded along a road and a power acquisition device attached on the vehicle. The power supply device includes a plurality of power supply core units, each core unit having two opposite magnetic poles and formed in a direction perpendicular to a longitudinal direction of the road; and one or more power supply lines disposed along the longitudinal direction such that adjacent two magnetic poles have different polarities. The power acquisition device includes power acquisition core units; a connection member for connecting the power acquisition core units such that the power acquisition core units are spaced from each other by a distance between the magnetic poles; and a power acquisition coil wound around the respective power acquisition core units or the connection member.
