Abstract

Systems, methods, and apparatus are disclosed for communicating with a charging system comprising a plurality of charging stations configured to charge an electric vehicle. At least one first signal is transmitted to the charging system via a first communication link while the electric vehicle is a first distance from at least one charging station of the plurality of charging stations. The at least one first signal is indicative of a vehicle identifier of the electric vehicle. At least one second signal is received from the at least one charging station of the plurality of charging stations via a second communication link while the electric vehicle is a second distance from the at least one charging station, the second distance less than the first distance. The at least one second signal is indicative of a charging station identifier of the at least one charging station.

First claim

What is claimed is:

1. A method of communicating with a charging system comprising a plurality of charging stations and a communication hub in communication with each charging station of the plurality of charging stations, each charging station configured to wirelessly charge an electric vehicle, the method comprising:
transmitting at least one first signal to the communication hub of the charging system via a first communication link while the electric vehicle is a first distance from at least one charging station of the plurality of charging stations, the at least one first signal indicative of a vehicle identifier of the electric vehicle;
receiving at least one second signal from the at least one charging station of the plurality of charging stations via a second communication link while the electric vehicle is a second distance from the at least one charging station of the plurality of charging stations, the second distance less than the first distance, the at least one second signal indicative of a charging station identifier of the at least one charging station; and
receiving at least one third signal from the communication hub via the first communication link, the at least one third signal comprising information regarding an identity of a charging station available for charging the electric vehicle.

2. The method of claim 1 , wherein the at least one third signal comprises information regarding an availability of one or more charging stations of the plurality of charging stations for use in wirelessly charging the electric vehicle.

3. The method of claim 1 , wherein the at least one first signal further comprises information regarding at least one of: a vehicle characteristic, driver of the electric vehicle, or a payment method expected to be used.

4. The method of claim 1 , wherein the at least one second signal further comprises information regarding at least one of: a number of available charging stations, a charging station characteristic, a schedule of costs for charging, or a charging menu of options available for charging the electric vehicle using the available charging stations.

5. The method of claim 1 , wherein the plurality of charging stations are configured to provide wireless power to the electric vehicle.

6. The method of claim 1 , further comprising transmitting at least one fourth signal to the charging system via the first communication link, the at least one fourth signal indicative of the charging station identifier.

7. The method of claim 1 , wherein the at least one charging station is configured to detect whether a non-electric vehicle is parked at the at least one charging station.

8. The method of claim 1 , further comprising allocating the at least one charging station to charging of the electric vehicle.

9. The method of claim 1 , further comprising determining an optimal charging station of the at least one charging station to allocate to charging of the electric vehicle.

10. The method of claim 1 , further comprising turning on and off a transmitter of the electric vehicle to avoid transmitting the at least one first signal during times at which such transmission is not desired.

11. The method of claim 1 , wherein receiving the at least one second signal from the at least one charging station occurs while the electric vehicle is within a parking space in which the at least one charging station is positioned and while the electric vehicle is not able to receive signals from other charging stations of the plurality of charging stations.

12. The method of claim 1 , further comprising using the second communication link for one or more of: electric vehicle guidance, electric vehicle alignment, charging control, status communication, authorization, identification, or payment management.

13. A method of communicating with an electric vehicle, the method comprising:
receiving at least one first signal from the electric vehicle via a first communication link while the electric vehicle is a first distance from at least one charging station of a charging system, the at least one first signal indicative of a vehicle identifier of the electric vehicle, the charging system comprising a communication hub in communication with each charging station of the at least one charging station, the communication hub receiving the at least one first signal;
transmitting at least one second signal to the electric vehicle via a second communication link while the electric vehicle is a second distance from the at least one charging station of the charging system, the second distance less than the first distance, the at least one second signal indicative of an identifier of the at least one charging station of the charging system; and
transmitting at least one third signal from the communication hub to the electric vehicle via the first communication link, the at least one third signal comprising information regarding an identity of a charging station available for charging the electric vehicle.

14. The method of claim 13 , wherein the at least one third signal comprises information regarding an availability of one or more charging stations of the at least one charging station for use in charging the electric vehicle.

15. The method of claim 13 , wherein the at least one first signal further comprises information regarding at least one of: a vehicle characteristic, driver of the electric vehicle, or a payment method expected to be used.

16. The method of claim 13 , wherein the at least one second signal further comprises information regarding at least one of: a number of available charging stations, a charging station characteristic, a schedule of costs for charging, or a charging menu of options available for charging the electric vehicle using the available charging stations.

17. The method of claim 13 , wherein the at least one charging station is configured to provide wireless power to the electric vehicle.

18. The method of claim 13 , further comprising receiving at least one fourth signal from the electric vehicle via the first communication link, the at least one fourth signal indicative of the charging station identifier.

19. The method of claim 13 , wherein the at least one charging station is configured to detect whether a non-electric vehicle is parked at the at least one charging station.

20. The method of claim 13 , further comprising determining an optimal charging station of the at least one charging station to allocate to charging of the electric vehicle.

21. A communication system of an electric vehicle, the communication system comprising:
a transmitter configured to transmit at least one first signal to a charging system via a first communication link while the electric vehicle is a first distance from at least one charging station of a plurality of charging stations of the charging system, the at least one first signal indicative of a vehicle identifier of the electric vehicle, the charging system comprising a communication hub in communication with each charging station of the plurality of charging stations, the transmitter configured to transmit the at least one first signal to the communication hub; and
at least one receiver configured to receive at least one second signal from the at least one charging station of the plurality of charging stations via a second communication link while the electric vehicle is a second distance from the at least one charging station, the second distance less than the first distance, the at least one second signal indicative of a charging station
