a communication unit communicatively coupled to the control module and configured to communicate alignment data with one or more devices associated with the vehicle for displaying a visual indicator to facilitate moving the vehicle such that the receiver is aligned with the charging unit; and

a housing body positionable beneath the vehicle for housing the charging unit and the control module, the charging unit being configured to be positioned at least partially under a street, the housing body having a conduit therethrough in which a communication medium is positionable for communicatively coupling the charging unit and the control module to a utility line, the housing body comprising a mounting ring for coupling the charging unit to a lid of the housing body, the lid of the housing body being configured to be substantially flush with the street.

2. The wireless charging station of claim 1, wherein the charging unit comprises an electromagnetic resonance charger.

3. The wireless charging station of claim 1, further comprising at least one sensor configured to determine the position of the receiver.

4. The wireless charging station of claim 1, further comprising a meter configured to determine an amount of power transferred by the charging unit.

5. The wireless charging station of claim 1, wherein the communication unit is further configured to transmit a location associated with the charging station to the one or more devices.

6. The charging station of claim 1, wherein the alignment data comprises a position of the receiver and a position of the charging unit based on measurements from at least one of a proximity sensor, a pressure sensor, or a GPS sensor positioned in an inner area of the housing body.

7. The charging station of claim 6, wherein the visual indicator includes a vehicle icon and charging unit icon illustrating the position of the receiver and the position of the charging unit relative to each other, wherein the visual indictor changes colors based on an alignment of the charging unit and the receiver, wherein the visual indicator is displayed on a user interface that includes an alert indicating alignment.

8. The charging station of claim 1, wherein the lid comprises a plurality of lights configured to indicate information about the condition of the charging station.

9. A wireless charging system comprising:

a charging station including;

a charging unit configured to wirelessly transfer power to a receiver in a vehicle;

a control module communicatively coupled to the charging unit and configured to activate the charging unit to transfer the power to the vehicle wirelessly in response to determining the receiver is aligned with the charging unit;

a communication unit communicatively coupled to the control module and configured to communicate information including alignment data with a server; and

a housing body positionable beneath the vehicle for housing the charging unit and the control module, the charging unit being configured to be positioned at least partially under a street, the housing body having a conduit therethrough in which a communication medium is positionable for communicatively coupling the charging unit and the control module to a utility line, the housing body comprising a mounting ring for coupling the charging unit to a lid of the housing body, the lid of the housing body being configured to be substantially flush with the street; and

the server communicatively coupled to the charging station and configured to maintain an application that is configured to be accessible through the one or more devices and to communicate the information regarding the charging station to the one or more devices, the alignment data being displayable via a user interface for providing a visual indicator to facilitate moving the vehicle such that the receiver is aligned with the charging unit.

10. The wireless charging system of claim 9, wherein the application is further configured to initiate a parking sequence function when the vehicle is near the charging station.

11. The wireless charging system of claim 10, further comprising one or more sensors communicatively coupled to the charging station configured to determine positional data indicating the vehicle'"'"'s location relative to the charging unit, the one or more sensors including at least one of a proximity sensor, a pressure sensor, or a GPS sensor positioned in an inner area of the housing body.

12. The wireless charging system of claim 10, wherein the application receives vehicle location data from the one or more devices, the positional data from the sensors, and the parking sequence function includes comparing the location data with the position data.

13. The wireless charging system of claim 10, wherein the parking sequence function is configured to provide the user interface with instructions to display a vehicle icon and charging unit icon to illustrate the position of the receiver relative to the position of the charging unit, and further to display the visual indicator that changes colors based on an alignment of the charging unit and the receiver and provides an alert when the vehicle has moved the receiver into alignment.

14. The charging system of claim 9, wherein the application comprises a payment function to be displayed via the user interface that facilitates paying for the amount of power transferred by the charging unit.

15. A method of wirelessly charging a vehicle comprising:

transmitting information about one or more charging stations to a device associated with a vehicle;

receiving from the device a request to charge the vehicle at a specific charging station from the one or more charging stations;

identifying when the vehicle is proximate the specific charging station;

providing alignment data to a second device associated with the vehicle that displays a visual indicator to facilitate moving the vehicle such that a receiver in the vehicle is aligned with a charging unit positioned in a housing body of the specific charging station, the housing body comprising a mounting ring that couples a charging unit to a lid of the housing body, the charging unit being positioned at least partially under a street and the lid of the housing body being substantially flush with the street; and

activating the charging unit in the specific charging station to transmit power to the receiver in the vehicle from a utility line communicatively coupled to the charging unit by a communication medium positioned in a conduit of the housing body.

16. The method of claim 15, wherein providing alignment data to a second device associated with the vehicle comprises:

receiving positional information indicating a position of the receiver with respect to the charging unit from at least one of a proximity sensor, a pressure sensor, or a GPS sensor positioned in an inner area of the housing body; and

transmitting the positional information to the charging unit.

17. The method of claim 16, wherein the positional information is displayed on a user interface as a vehicle icon that illustrates the position of the receiver and a charging unit icon that illustrates a position of the charging unit relative to the position of the receiver, the charging unit icon capable of overlapping with the vehicle icon, and the user interface includes an alert indicating alignment.

18. The method of claim 15, wherein the first device and second device are the same device.
