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.

Claims

1. A method, comprising:

establishing, by a controller operating in a vehicle, an initial communication with a charging station;

establishing, by the controller during the initial communication, a parameter for superimposing a signal onto an electrical power delivered via the charging station, the parameter based on an electronic build sheet associated with the vehicle;

terminating, by the controller, the initial communication with the charging station;

receiving, by the controller, the electrical power delivered via the charging station;

authenticating, by the controller, the superimposing of the signal onto the electrical power according to the parameter based on the electronic build sheet; and

charging, by the controller, a battery in the vehicle in response to a successful authentication of the superimposing of the signal onto the electrical power according to the parameter based on the electronic build sheet.

2. The method of claim 1, further comprising calculating an expected frequency of the signal based on 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 hardware processor; and

a memory device, the memory device storing executable instructions which, responsive to being executed by the hardware processor, causes the hardware processor to perform operations comprising;

establishing a communication between a vehicle and a charging station;

determining a radio frequency identifier communicated by a component operating in the vehicle;

determining a frequency based on the radio frequency identifier communicated by the component operating in the vehicle;

superimposing a signal onto an electrical power to generate transformed electrical power, the signal having the frequency based on the radio frequency identifier communicated by the component operating in the vehicle; and

sending the transformed electrical power to charge a battery in the vehicle.

8. The system of claim 7, wherein the radio frequency identifier is communicated by the component operating in the vehicle via a broadcast.

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

10. The system of claim 9, wherein the operations further comprise authenticating the superimposing of the signal according to option codes described by the manufacturer build sheet.

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 a payment for charging the battery.

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

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

15. A memory device storing instructions which, when executed by a processor, cause the processor to perform operations, comprising:

establishing a communication between a vehicle and a charging station;

receiving a radio frequency identifier communicated by a component operating in the vehicle;

determining a frequency based on the radio frequency identifier communicated by the component operating in the vehicle;

receiving electrical power from an electrical grid;

superimposing a signal onto the electrical power according to the frequency to generate transformed electrical power; and

sending the transformed electrical power from the charging station to charge a battery in the vehicle.

16. The memory device of claim 15, wherein the component comprises a tire pressure monitoring system.

17. The memory device of claim 15, wherein the operations further comprise retrieving a manufacturer build sheet associated with the vehicle.

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

19. The memory device of claim 15, wherein the operations further comprise retrieving financial information associated with the vehicle.

20. The memory device of claim 15, wherein the operations further comprise conducting an electronic financial transaction as a payment for charging the battery.
