1. An electric vehicle charging system, comprising:
- a secondary resonant coil operatively connected to a load within an electric vehicle and which is tuned to have a resonant frequency that is substantially the same as a resonant frequency of a primary resonant coil located outside the electric vehicle, wherein the primary resonant coil is operatively connected to a source of electrical power;
a coil located between the primary resonant coil and the secondary resonant coil, wherein the coil electromagnetically couples electrical power from the primary resonant coil to the secondary resonant coil for extending an electromagnetic coupling distance over which the electrical power can be transferred between the source and the load; and
a conversion element coupled to the secondary resonant coil for converting the electrical power received by the secondary resonant coil to produce converted electrical power, wherein the converted electrical power is coupled to the load.

Abstract
A method and system for efficient distribution of power using wireless means, and a system and method for wireless power distribution to provide electric devices, such as vehicles with a way to continuously and wirelessly collect, use and charge their power systems and thereby use the transmitted power for operation. The system and method allows a hybrid, simplified and less costly way to charge devices, such as vehicles so that the devices continuously operate while charging/recharging.
