Abstract

A wireless charging system for a vehicle and a method of operating is provided. The system includes a vehicle having a floor pan disposed opposite a ground surface. At least one battery is provided that is configured to provide energy to the vehicle. At least one power receiving coil is electrically coupled to the at least one battery and arranged within a housing adjacent the floor pan opposite the ground surface.

First claim

What is claimed is:

1. A wireless charging system comprising:
a vehicle having a floor pan disposed opposite a ground surface;
at least one battery, configured to provide energy to the vehicle;
a housing receivable within the vehicle adjacent to the floor pan, the housing including a body and a cover environmentally sealable to the body; and
at least one power receiving coil electrically coupled to the at least one battery and arranged within the housing, wherein a configuration of the cover is selected to shape a flow of electromagnetic radiation provided to the at least one power receiving coil.

2. The system according to 1 , wherein the housing further comprises an enclosure space that physically conforms to the power receiving coil(s).

3. The system according to 2 , wherein the housing forms at least a portion of the floor pan, wherein the floor pan and housing form a substantially contiguous surface.

4. The system according to 2 , wherein the housing is disposed a distance from the ground surface that is equal to or greater than an area of the floor pan adjacent the housing.

5. The system according to 2 , wherein the housing includes a surface adjacent the floor pan, the surface being configured to allow magnetic and/or electro-magnetic radiation to pass through to inductively couple the receiving coil to a transmitting coil during operation.

6. The system according to claim 1 , wherein the at least one power receiving coil is movably disposed within the housing.

7. The system according to claim 6 , further comprising a movement mechanism coupled to the at least one power receiving coil, the movement mechanism configured to move the at least one power receiving coil within the housing.

8. A wireless charging system comprising:
a vehicle having a floor pan disposed opposite a ground surface;
at least one battery, configured to provide energy to the vehicle;
a receiving coil electrically coupled to the at least one battery;
a housing receivable within the vehicle and having a housing surface facing the ground surface, the receiving coil being arranged within the housing; and
a movement mechanism operably coupled to the receiving coil, the movement mechanism being operable to move the receiving coil within the housing away from the housing surface facing the ground surface to achieve a spacing associated with an optimal current transfer between the receiving coil and a transmitting coil located at the ground surface coil.

9. The system according to 8 , wherein the housing further comprises an enclosure space that physically conforms to the receiving coil.

10. The system according to 8 , wherein the housing further comprises a lower surface and the lower surface is aligned with the floor pan.

11. The system of claim 10 , wherein the lower surface is made from a material configured to allow electromagnetic radiation to pass therethrough.

12. The system of claim 8 , wherein the movement mechanism is operably coupled to the housing, the movement mechanism being operable to move the housing relative to the vehicle to adjust the floor pan to ground surface clearance.
