Abstract

Methods, systems, and products charge a battery in a vehicle. A charging station and the vehicle negotiate charging parameters. When the vehicle receives electrical power from the charging station, the vehicle checks the electrical power for the parameters. Should the electrical power fail to exhibit the parameters, charging is terminated.

First claim

What is claimed is:

1. A method, comprising:
retrieving, by a controller operating in a vehicle, an electronic build sheet describing option codes associated with the vehicle;
establishing, by the controller, an initial communication with a charging station;
establishing, by the controller during the initial communication, parameters for superimposing a signal onto electrical power delivered by the charging station, the parameters based on the option codes described by the electronic build sheet;
terminating, by the controller, the initial communication with the charging station;
receiving, by the controller, the signal superimposed onto the electrical power delivered from the charging station;
authenticating, by the controller, superimposition of the signal onto the electrical power according to the parameters based on the option codes described by the electronic build sheet; and
charging, by the controller, a battery in the vehicle in response to a successful authentication.

2. The method of claim 1 , further comprising calculating an expected frequency of the signal using the option codes in the electronic build sheet.

3. The method of claim 1 , further comprising receiving radio frequency identifiers from a tire pressure monitoring system.

4. The method of claim 1 , further comprising retrieving financial information associated with the vehicle.

5. The method of claim 1 , further comprising retrieving a credit card number associated with the vehicle.

6. The method of claim 1 , further comprising conducting an electronic financial transaction as payment for the charging the battery.

7. A system, comprising:
a processor; and
a memory storing code that when executed causes the processor to perform operations, the operations comprising:
establishing communication between a vehicle and a charging station;
determining a radio frequency identifier broadcast by a component operating in the vehicle;
determining a frequency based on the radio frequency identifier broadcast by the component operating in the vehicle;
receiving electrical power from an electrical grid;
superimposing a signal onto the electrical power to form transformed electrical power, the signal having the frequency based on the radio frequency identifier; and
sending the transformed electrical power from the charging station to charge a battery in the vehicle.

8. The system of claim 7 , wherein the operations further comprise retrieving a manufacturer's build sheet associated with the vehicle.

9. The system of claim 8 , wherein the operations further comprise authenticating a superimposition of the signal using option codes described by the manufacturer's build sheet.

10. The system of claim 7 , wherein the operations further comprise retrieving financial information associated with the vehicle.

11. The system of claim 7 , wherein the operations further comprise retrieving a credit card number associated with the vehicle.

12. The system of claim 7 , wherein the operations further comprise conducting an electronic financial transaction as payment for charging the battery.

13. The system of claim 7 , wherein the operations further comprise terminating charging in response to a failed authentication.

14. A memory device storing instructions that when executed cause a processor to perform operations, the operations comprising:
establishing communication between a vehicle and a charging station;
retrieving a radio frequency identifier broadcast by a component operating in the vehicle;
determining a frequency based on the radio frequency identifier broadcast by the component operating in the vehicle;
receiving electrical power from an electrical grid;
superimposing a signal onto the electrical power at the frequency based on the radio frequency identifier to form transformed electrical power; and
sending the transformed electrical power from the charging station to charge a battery in the vehicle.

15. The memory device of claim 14 , wherein the operations further comprise receiving the radio frequency identifier from a tire pressure monitoring system.

16. The memory device of claim 14 , wherein the operations further comprise retrieving a manufacturer's build sheet associated with the vehicle.

17. The memory device of claim 16 , wherein the operations further comprise authenticating the frequency using option codes described by the manufacturer's build sheet.

18. The memory device of claim 14 , wherein the operations further comprise retrieving financial information associated with the vehicle.

19. The memory device of claim 18 , wherein the operations further comprise conducting an electronic financial transaction as payment for charging the battery.
