Parking alignment sequence for wirelessly charging an electric vehicle

A system comprising:

• a processing device of a user device;
• and
• a memory device on which instructions are stored for causing the processing device to:
• determine 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;
• generate 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;
• determine that the electric vehicle is located within a first predetermined distance from the charging station that is physically separate from the electric vehicle;
• determine 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;
• receive 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;
• generate a second user interface for display to a user associated with the electric vehicle, 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
• activate 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.

A non-transitory computer-readable medium in which instructions executable by a processing device of a user device are stored for causing the processing device to:

• determine 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;
• generate 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;
• determine that the electric vehicle is located within a first predetermined distance from the charging station that is physically separate from the electric vehicle;
• determine 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;
• receive 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 being located within the first predetermined distance from the charging station;
• generate a second user interface for display to a user associated with the electric vehicle, 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
• activate 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.
