6 . The electronic device of claim 1 , wherein, for the wireless communication association, whether the wireless communication association is successful is determined according to whether a vendor-specific element (VSE) field of a message which is received after the first EVSE is selected is consistent with identifiable information of the first EVSE.

7 . An electronic device mounted on an electric vehicle supply equipment (EVSE), the electronic device comprising:

a processor; and

a memory configured to store at least one instruction to be executed by the processor,

wherein by executing the at least one instruction, the processor is configured to:

broadcast identifiable information of the electronic device,

perform positioning until an electric vehicle (EV) is at a location capable of being charged from the EVSE when wireless communication association is established with the EV that has received the broadcast identifiable information, and

perform pairing with a first EVSE so that the EV receives power from the first EVSE, and

wherein the electronic device is one of a first type or a second type classified according to a distance and a relative location from a power transmission device of the EVSE,

wherein the electronic device is determined as the first type based on the electronic device is located within a range from the power transmission device of the EVSE, and

wherein the electronic device is determined as the second type operating differently from the first type in the positioning based on the electronic device is located out of the range from the power transmission device of the EVSE.

8 . The electronic device of claim 7 , wherein, for the positioning, whether the EV is at the location capable of being charged from the EVSE is determined in cooperation with a second electronic device mounted on the EVSE.

9 . The electronic device of claim 7 , wherein, for the positioning, when a distance between a power reception device of the EV and the power transmission device is within a predetermined range, a location of the power reception device is estimated, using a location of an electronic device of the first type mounted on the EV which is close to the power reception device from an electronic device of the second type mounted on the EVSE.

10 . The electronic device of claim 7 , wherein, for the pairing, when the processor concludes as a result of the positioning that the EV is at the location capable of being charged from the EVSE, whether the electronic device is to be deactivated is determined according to whether the electronic device is a first type or a second type, which is classified according to a distance and a relative location from the power transmission device of the EVSE.

11 . The electronic device of claim 7 , wherein, for the pairing, whether the pairing is successful is determined according to whether a selected EVSE pairing and positioning device identifier (PPDID) extracted from a message received from the EV is consistent with a PPDID of the electronic device.
