Parking alignment sequence for wirelessly charging an electric vehicle
First Claim
1. A method comprising:
- determining, by a processing device of a user device, a location of a charging station based on a communication that is over a cellular network and that is between the user device and the charging station, the charging station having a transmitter for wirelessly transmitting power to a receiver of an electric vehicle for charging the electric vehicle;
generating, by the processing device, a first user interface for display to a user associated with the electric vehicle, the first user interface having directions to the charging station from a current location of the user device;
determining, by the processing device, that the electric vehicle is located within a first predetermined distance from the charging station that is physically separate from the electric vehicle;
determining, by the processing device, alignment data at least in part by measuring a strength of a surrounding electromagnetic field using one or more low frequency antennas coupled to at least one of the transmitter or the receiver;
receiving, by the processing device, the alignment data wirelessly transmitted from the charging station via a communication path that is independent of the cellular network in response to determining that the electric vehicle is located within the first predetermined distance from the charging station;
generating, by the processing device, a second user interface for display to the user, the second user interface having alignment instructions for moving the electric vehicle into alignment with the charging station based on the alignment data in response to the electric vehicle being located within the first predetermined distance from the charging station; and
activating, by the processing device, a primary coil associated with the transmitter to a lower power state in which power to the primary coil is below that of a higher power state in response to determining that the receiver is within a second predetermined distance from the transmitter.

Abstract
A parking alignment sequence for wirelessly charging an electric vehicle can include determining a location of a charging station by a processing device of a user device based on communication over a cellular network. The charging station can have a transmitter for wirelessly transmitting power to a receiver of the electric vehicle. A first user interface having directions to the charging station from a current location of the user device can be displayed. Alignment data can be wirelessly received via a communication path that is independent of the cellular network in response to the electric vehicle being located within a predetermined distance from the charging station. A second user interface having alignment instructions can be displayed for moving the electric vehicle into alignment based on the alignment data in response to the electric vehicle being located within the predetermined distance from the charging station.
