Wireless energy transfer with multi resonator arrays for vehicle applications
First Claim
1. A vehicle powering wireless power receiver, comprising:
- an array of electromagnetic resonators configured for attachment to the vehicle, wherein each resonator in the array comprises a magnetic material and a coil comprising a plurality of loops of conducting material encircling the magnetic material; and
a load coupled to the array and to a drive system of the vehicle,wherein each resonator in the array is oriented so that electrical current circulating within the resonator'"'"'s coil generates a magnetic dipole moment that falls within a plane defined by the resonator'"'"'s magnetic material; and
wherein the array is configured to receive power from a resonant, non-radiative wireless power source and to deliver power to the load.

Abstract
A vehicle powering wireless receiver for use with a first electromagnetic resonator coupled to a power supply. The wireless receiver includes a load configured to power the drive system of a vehicle using electrical power, and a second electromagnetic resonator adapted to be housed upon the vehicle and configured to be coupled to the load, at least one other electromagnetic resonator configured with the first electromagnetic resonator and the second electromagnetic resonator in an array of electromagnetic resonators to distribute power over an area, wherein the second electromagnetic resonator is configured to be wirelessly coupled to the array to provide resonant, non-radiative wireless power to the second electromagnetic resonator from the first electromagnetic resonator.
