Systems, methods, and apparatus related to detecting and identifying electric vehicle and charging station

摘要

Systems, methods, and apparatus are disclosed for communicating between a charging station and an electric vehicle. In one aspect, a method of pairing a charging station with an electric vehicle is provided, including providing wireless power via a magnetic field having a first intensity level that is sufficient to charge or power the electric vehicle, providing an information signal via the magnetic field when the magnetic field is set at a second intensity level that is lower than the first intensity level, the information signal uniquely identifying the charging station from a plurality of charging stations, communicating with the electric vehicle via a communication link that is different from the magnetic field, communicating comprising communicating with the electric vehicle parking guidance information to the location of the charging station, and establishing the communication link based at least in part on the information signal provided via the magnetic field.

主权项

1. An apparatus for providing wireless power, comprising:
a transmitter comprising one or more coils configured to provide wireless power via a magnetic field having a first intensity level that is sufficient to charge or power an electric vehicle, the one or more coils further configured to provide an information signal via the magnetic field when the magnetic field is set at a second intensity level that is lower than the first intensity level, the information signal having one or more characteristics that uniquely identify the transmitter from a plurality of transmitters; and a transceiver connected to the transmitter and configured to:
communicate with the electric vehicle via a communication link that is different from the magnetic field; andestablish the communication link with the electric vehicle based at least in part on the information signal provided via the magnetic field, the transmitter further configured to communicate with the electric vehicle, via the communication link, parking guidance information to the location of the one or more coils.
