Abstract

A system that automatically detects the presence of an automobile that can operate wirelessly to recharge the battery therein, and detects account information associated with that automobile. When the account information is properly detected, the amount of power delivered is metered, and thereafter the power used by a user is Bill to the user at a markup based on that distributed by the distribution company.

Claims

6-1. A method as in claim 1, wherein said wirelessly supplying power comprises applying power using a magnetically resonant antenna which includes an inductor and a capacitor, and has a Q value greater than 1000.

8. An apparatus comprising:

a wireless transmitter, located adjacent a vehicle parking space, and supplying magnetically resonant power via said wireless transmitter; and

a billing computer, receiving billing information for a specific account associated with a specific vehicle, based on an amount of power that has been wirelessly supplied.

9. An apparatus as in claim 8, further comprising a billing account detector that detects identification information about the vehicle, and meters an amount of power that is supplied to the vehicle.

10. An apparatus as in claim 9, wherein said billing computer determines whether said identification information is associated with an existing account, and enables said wireless transmitter to supply said power only once the account is determined to be associated with said existing account.

11. An apparatus as in claim 10, wherein said billing account detector includes a cryptographic processor that verifies cryptographic information within said identification information, and said billing computer determines whether said identification information is associated with an existing account, and enables said wireless transmitter to supply said power only once the account is determined to be associated with said existing account.

12. An apparatus as in claim 11, wherein said cryptographic operation comprises verifying that the vehicle is associated with a registered account for billing data.

13. An apparatus as in claim 8, wherein said wireless transmitter supplies power using a magnetically resonant antenna which includes an inductor and a capacitor, and has a Q value greater than 1000.

14. An apparatus as in claim 9 wherein said billing account detector wirelessly identifies the user.

15. A method comprising:

purchasing power from a power utility company;

wirelessly supplying the power to a vehicle that operates from electric power; and

providing billing data to an owner of the vehicle based on an amount of power that has been wirelessly supplied, where the billing data includes a profit over the power that has been purchased from the power utility company.

16. A method as in claim 15, wherein said supplying comprises detecting identification information about the vehicle, and metering an amount of power that is supplied to the vehicle.

17. A method as in claim 16, wherein said supplying further comprises determining whether said identification information is associated with an existing account, and wirelessly supplying said power only once the account is determined to be associated with said account.
