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.
Claims19
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.

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.

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.
