Abstract

A method and system for detecting a charger are provided. The method includes receiving, by a controller, charger information from at least one charger present within a network area of a vehicle. A sensed current is then transmitted from a receiving pad of the vehicle to the charger or a charger side transmitting pad based on the charger information. Further, the method may include detecting the charger and the transmitting pad having priority based on a voltage and a current induced by the sensed current.

Claims

1. A method for detecting a charger, comprising:

receiving, by the controller, charger information from at least one charger present within a network area of a vehicle;

transmitting, by the controller, a sensed current from a receiving pad of the vehicle to the charger or a charger side transmitting pad based on the charger information; and

determining, by the controller, the charger and the transmitting pad that has priority based on a voltage and a current induced by the sensed current.

2. The method of claim 1, wherein in the reception of the charger information, the charger information includes at least one selected from the group consisting of:

a unique identifier of the at least one charger or transmitting pad, a number of chargers, a number of transmitting pads per the charger, an availability of the charger, and a type of the transmitting pad of the charger.

3. The method of claim 1, further comprising:

selecting, by the controller, one charger as a charger for the vehicle when the number of chargers detected is one.

4. The method of claim 1, further comprising:

transmitting, by the controller, information regarding a current, a voltage, a power, a duration, or a start time from the receiving pad of the vehicle to the plurality of chargers or transmitting pads.

5. The method of claim 1, further comprising:

measuring, by the controller, a voltage and a current induced from each of the plurality of chargers or transmitting pads based on the transmitted sensed current within the charger.

6. The method of claim 1, wherein the determination of the charger and the transmitting pad that has priority based on the voltage and the current induced by the sensed current includes:

determining, by the controller, the charger and the transmitting pad with a voltage and a current induced by the sensed current is equal to or greater than a preset magnitude.

7. A system for detecting a charger, comprising:

a memory configured to store program instructions; and

a controller configured to execute the program instructions, the program instructions when executed configured to;

receive charger information from at least one charger present within a network area of a vehicle;

transmit a sensed current from a receiving pad of the vehicle to the charger or a charger side transmitting pad based on the charger information; and

determine the charger and the transmitting pad that has priority based on a voltage and a current induced by the sensed current.

8. The system of claim 7, wherein the charger information includes at least one selected from the group consisting of:

a unique identifier of the at least one charger or transmitting pad;

the number of chargers;

the number of transmitting pads for the charger;

the availability of the charger; and

a type of the transmitting pad of the charger.

9. The system of claim 7, wherein the controller is further configured to:

select one charger as a charger for the vehicle when the number of chargers available or determined is one.

10. The system of claim 7, wherein the controller is further configured to:

determine the charger and the transmitting pad whose magnitude of the voltage and the current induced by the sensed current is equal to or greater than a preset magnitude.

13. A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:

program instructions that receive charger information from at least one charger present within a network area of a vehicle;

program instructions that transmit a sensed current from a receiving pad of the vehicle to the charger or a charger side transmitting pad based on the charger information; and

program instructions that determine the charger and the transmitting pad that has priority based on a voltage and a current induced by the sensed current.

14. The non-transitory computer readable medium of claim 13, further comprising:

program instructions that selecting, by the controller, one charger as a charger for the vehicle when the number of chargers available or determined is one.

15. The non-transitory computer readable medium of claim 13, further comprising:

program instructions that transmitting, by the controller, information regarding a current, a voltage, a power, a duration or a start time to the plurality of chargers or transmitting pads.
