1. A method for wireless energy transfer, comprising:
- providing an electrified surface comprising one or more energy transmission systems adapted to wirelessly transfer energy across an airgap;
positioning an electrically chargeable vehicle comprising a energy reception system within electromagnetic proximity of said electrified surface;
establishing a resonant inductive coupling between said energy transmission system and said energy reception system;
establishing input unity power factor, maximum real power transmission and low switching losses at an operating switching frequency range of 17 kHz to at least 35 kHz;
auto-adjusting an energy transfer frequency to compensate for misalignment between said electrified surface and said electrically chargeable vehicle;
regulating said wireless energy transfer to full power (10 kW-150 kW) based on the charge state or propulsion requirements of said electrically chargeable vehicletransferring energy from said electrified surface to said electrically chargeable vehicle.
