Methods, systems, and products for charging batteries

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.
