Abstract

A charging system includes: first stations configured to determine whether to transmit charger detection signals based on a preset charging mode and a state of charge of a battery included in a vehicle; and second stations configured to receive the charger detection signals or to transmit beacon signals to the transmitter based on the state of charge of the battery.

Claims

1. A charging system, comprising:

first stations configured to determine whether to transmit charger detection signals based on a preset charging mode and a state of charge of a battery included in a vehicle; and

second stations configured to receive the charger detection signals or to transmit beacon signals to a transmitter based on the state of charge of the battery.

2. The charging system of claim 1, wherein when the preset charging mode is a first charging mode, or when the state of charge of the battery is lower than a preset reference value and the preset charging mode is a second charging mode, the first stations transmit the charger detection signals to the second stations.

3. The charging system of claim 1, wherein when the preset charging mode is a second charging mode and the state of charge of the battery is higher than a preset reference value, the first stations receive any of the beacon signals transmitted from the second stations.

4. The charging system of claim 3, wherein the first stations select any of the beacon signals to be received based on a kind of the second stations.

5. The charging system of claim 4, wherein a first station of the first stations selects a second station of the second stations that is transmitting the selected beacon signal in order to receive power from the selected second station.

6. The charging system of claim 1, wherein the beacon signals include charging information of each of the second stations.

7. The charging system of claim 2, wherein the second stations include charging stations and non-charging stations, and

the charging stations of the second stations transmit response signals to the first stations in response to the charger detection signals transmitted from the first stations.

8. The charging system of claim 2, wherein the second stations include charging stations and non-charging stations, and

when there are no charging stations of the second stations receiving the charger detection signals transmitted from the first stations, the non-charging stations of the second stations disregard the charger detection signals transmitted from the first stations or transmit the charger detection signals to other second stations within a signal arrival range of the non-charging stations.

9. The charging system of claim 8, wherein the charging stations of the other second stations within the signal arrival range of the non-charging stations transmit response signals to the non-charging stations in response to the charger detection signals transmitted from the non-charging stations.

10. The charging system of claim 9, wherein the non-charging stations transmit the response signals received from the charging stations of the other second stations within the signal arrival range of the non-charging stations to the first stations.

11. The charging system of claim 8, wherein when there are no charging stations of the other second stations receiving the charger detection signals within the signal arrival range of the non-charging stations, the non-charging stations of the other second stations within the signal arrival range of the non-charging stations transmit the charger detection signals to other second stations within the signal arrival range of the non-charging stations of other second stations within the signal arrival range of the non-charging stations or disregard the charger detection signals.

12. A charging vehicle, comprising:

a controller configured to determine whether to transmit charger detection signals based on a preset charging mode and a state of charge of a battery included in a vehicle;

a transmitter configured to transmit the charger detection signals to a plurality of access points based on the determination of whether to transmit the charger detection signals; and

a receiver configured to receive beacon signals from the plurality of access points based on the determination of whether to transmit the charger detection signals.

13. The charging vehicle of claim 12, wherein when the preset charging mode is a first charging mode, or when the preset charging mode is a second charging mode and the state of charge of the battery is lower than a preset reference value, the controller instructs the transmitter to transmit the charger detection signals to the plurality of access points.

14. The charging vehicle of claim 12, wherein when the preset charging mode is a second charging mode and the state of charge of the battery is higher than a preset reference value, the controller instructs the transmitter to not transmit the charger detection signals and instructs the receiver to receive the beacon signals from the plurality of access points.
