Abstract
Described herein are embodiments of a noncontact electric power receiving high-Q device magnetic resonator for an electrically powered vehicle that includes an electric power receiving high-Q magnetic resonator for receiving electric power from another magnetic resonator, which receives electric power from a power source to generate an electromagnetic field, by resonating with said another magnetic resonator through said electromagnetic field.
Claims
exact text as granted — not AI-modified1 . A noncontact electric power receiving high-Q device magnetic resonator for an electrically powered vehicle comprising:
an electric power receiving high-Q magnetic resonator for receiving electric power from another magnetic resonator, which receives electric power from a power source to generate an electromagnetic field, by resonating with said another magnetic resonator through said electromagnetic field.
2 . The noncontact electric power receiving high-Q device magnetic resonator for an electrically powered vehicle according to claim 1 , wherein: said another magnetic resonator includes a first self-resonant coil for receiving the electric power from the power source to generate said electromagnetic field; and said electric power receiving resonator includes a self-resonant coil for receiving the electric power from said first self-resonant coil by resonating with said first self-resonant coil through said electromagnetic field, and outputting power.
3 . An electrically powered vehicle comprising:
an electric power receiving high-Q magnetic resonator for receiving electric power from an electric power transmitting resonator provided external to the vehicle, by resonating with said electric power transmitting resonator through an electromagnetic field.
4 . The electrically powered vehicle according to claim 3 , wherein: said electric power transmitting resonator includes a first self-resonant coil for receiving the electric power from the power source to generate said electromagnetic field; and said electric power receiving high-Q device resonator includes a self-resonant coil for receiving the electric power from said first self-resonant coil by resonating with said first self-resonant coil through said electromagnetic field, and outputting the electric power.Cited by (0)
