Safety systems for wireless energy transfer in vehicle applications

摘要

A vehicle powering wireless receiver for use with a first electromagnetic resonator coupled to a power supply. The wireless receiver including a load configured to power the drive system of a vehicle using electrical power, a second electromagnetic resonator adapted to be housed upon the vehicle and configured to be coupled to the load, a safety system for to provide protection with respect to an object that may become hot during operation of the first electromagnetic resonator. The safety system including a detection subsystem configured to detect the presence of the object in substantial proximity to at least one of the resonators, and a notification subsystem operatively coupled to the detection subsystem and configured to provide an indication of the object, wherein the second resonator is configured to be wirelessly coupled to the first resonator to provide resonant, non-radiative wireless power to the second resonator from the first resonator.

主权项

1. A vehicle powering wireless receiver, comprising:
a load coupled to a drive system of the vehicle; an electromagnetic resonator coupled to the load and configured for attachment to the vehicle, wherein the electromagnetic resonator is configured to receive power from a resonant, non-radiative wireless power source and to deliver power to the load; and a safety system configured to detect metal objects positioned in proximity to at least one of the power source and the electromagnetic resonator, the safety system comprising:
a detection subsystem comprising one or more inductive loops formed of conductive material; anda notification subsystem coupled to the detection subsystem and configured to generate a notification signal when a metal object is detected by the detection subsystem.
