CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2019-0167474, filed on Dec. 16, 2019 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND

The disclosure relates to a charger sharing system and charger sharing method.

A charger is a device for charging electricity in a battery built in an electric vehicle, and may be classified into various types according to a charging speed and an installation type. Rapid chargers can be recharged quickly but are expensive to install. The slow charger takes a long time to fully charge and is usually installed for home use.

The charger needs as little as 30 minutes or as long as 6 hours to fully charge the vehicle battery. In addition, since the vehicle needs space to park while charging, the charging of the electric vehicle soon leads to parking. Therefore, there is a limit to the number of chargers installed in multi-family houses or public places where the parking space is limited. In Korea, many multi-family homes have many limitations in the use and installation of chargers and many problems with installing and using chargers.

For example, if all chargers are in use, a waiter may have to wait up to six hours. In addition, the owner of the vehicle occupying the charger is obliged to move the vehicle when charging is complete. This situation can be inconvenient for both the waiter and the owner of the vehicle occupying the charger. Sometimes severe conflicts arise between the waiter and the occupant. While the number of electric vehicle drivers is increasing, the supply of chargers is insufficient, and the inconvenience of users in sharing chargers is increasing.

SUMMARY

Therefore, it is an aspect of the disclosure to provide a charger sharing system that enable users to effectively share a charger of a vehicle, and a charger sharing method.

In addition, it is an aspect of the disclosure to provide a charger sharing system capable of activating charger sharing by providing benefits to users, and relieving inconvenience caused in the charger sharing process, and a charger sharing method.

In accordance with one aspect of the disclosure, a charger sharing system includes: an occupant terminal, a subscriber terminal, and a charger connected through a network, and the charger may be configured to receive a reservation request message comprising charger reservation information from the subscriber terminal and determine whether to register the charger reservation information based on a reservation type included in the charger reservation information.

The charger may be configured to register the charger reservation information when the reservation type is a free reservation and transmit the charger reservation information to the occupant terminal when the reservation type is a paid reservation.

The charger sharing system may further include: a bidder terminal connected via the network, and the charger may be configured to confirm a bid setting information from the occupant terminal when the reservation type is paid reservation, and receive a bid message from the bidder terminal based on the bid setting information or register the charger reservation information with the charger.

The charger may be configured to transmit a bid information included in the bid message to the occupant terminal based on receiving the bid message from the bidder terminal and register the bid information based on receiving a reservation change message from the occupant terminal.

The charger may be configured to register the charger reservation information when the bid message is not received from the bidder terminal or a reservation change message is not received from the occupant terminal.

The charger may be configured to transmit a notification message to the subscriber terminal after charging of the occupant vehicle is completed.

The charger may be configured to obtain a parking setting information of the occupant vehicle from the occupant terminal when charging of the occupant vehicle is completed, and execute an autonomous parking of the occupant vehicle based on the parking setting information or transmit a control authority of the occupant vehicle to the subscriber terminal.

The charger may be configured to, when executing the autonomous parking of the occupant vehicle, transmit a parking location information and a parking completion message to the occupant terminal after moving the occupant vehicle to a predetermined location.

The charger may be configured to receive the parking location information and the parking completion message of the occupant vehicle from the subscriber terminal when transmitting the control authority of the occupant vehicle to the subscriber terminal and transmit the parking location information and the parking completion message to the occupant terminal.

The charger may be configured to transmit a payment information to the subscriber terminal after charging of the occupant vehicle is completed when the reservation type is paid reservation.

In accordance with another aspect of the disclosure, a charger sharing method includes: receiving a reservation request message comprising charger reservation information from the subscriber terminal by the charger; and determining whether to register the charger reservation information based on a reservation type included in the charger reservation information.

The determining whether to register the charger reservation information may include: registering the charger reservation information when the reservation type is a free reservation; and transmitting the charger reservation information to the occupant terminal when the reservation type is a paid reservation.

The determining whether to register the charger reservation information may include: confirming a bid setting information from the occupant terminal when the reservation type is paid reservation; and receiving a bid message from the bidder terminal based on the bid setting information or register the charger reservation information with the charger.

The determining whether to register the charger reservation information may include: transmitting a bid information included in the bid message to the occupant terminal based on receiving the bid message from the bidder terminal; and registering the bid information based on receiving a reservation change message from the occupant terminal.

The determining whether to register the charger reservation information may include: registering the charger reservation information when the bid message is not received from the bidder terminal or a reservation change message is not received from the occupant terminal.

The charger sharing method may further include: transmitting a notification message to the subscriber terminal after charging of the occupant vehicle is completed.

The charger sharing method may further include: obtaining a parking setting information of the occupant vehicle from the occupant terminal when charging of the occupant vehicle is completed; and executing an autonomous parking of the occupant vehicle based on the parking setting information or transmitting a control authority of the occupant vehicle to the subscriber terminal.

The charger sharing method may further include: when executing the autonomous parking of the occupant vehicle, transmitting a parking location information and a parking completion message to the occupant terminal after moving the occupant vehicle to a predetermined location.

The charger sharing method may further include: receiving the parking location information and the parking completion message of the occupant vehicle from the subscriber terminal when transmitting the control authority of the occupant vehicle to the subscriber terminal; and transmitting the parking location information and the parking completion message to the occupant terminal.

The charger sharing method may further my include: transmitting a payment information to the subscriber terminal after charging of the occupant vehicle is completed when the reservation type is paid reservation.
