Wireless energy transfer antennas and energy charging systems
First Claim
1. A method of charging a battery in a transportable power using device from a fixed power delivery location comprising the steps of:
- (a) activating a transmitting antenna at the power delivery location at a low power level;
(b) testing to determine that power is being transferred from the delivery location antenna to a receiving antenna associated with the power using device; and
(c) upon determining that power is being transferred at or above a predetermined level, increasing the power level at the delivery location.

Abstract
A resonant wireless energy transfer system comprises first and second antennas made up of dual parallel wire helixes wherein the wires are terminated by short wires. Voltage controlled variable capacitors are connected into the antennas to permit progressive variation between folded dipole and normal dipole operating modes such that optimum energy transfer can be achieved between the antennas over a wide range of antenna separation distances. A vehicle battery charging system using the above-described antennas is provided including an installation which allows purchase of battery charging power by members of the general public. In-vehicle energy transfer for sensors, computers, cell phones and the like is also described.
