1 is a flowchart showing a method for providing an electric vehicle charging service according to an embodiment of the present invention. The electric vehicle charging method illustrated in FIG. 1 may be performed by an electric vehicle charging system including an outlet 100, a management server 200, and a user terminal 300.

First, when the user who wants to charge the electric vehicle recognizes the user terminal 300, the outlet 100 recognizes the user terminal 300 (S10), and transmits the outlet ID to the recognized user terminal 300 (S20). . The outlet ID is used by the management server 200 to identify the outlet 100.

In one embodiment, when the user terminal 300 approaches within a certain distance, the outlet 100 may recognize the user terminal 300 and transmit the outlet ID. In another embodiment, the outlet 100 recognizes the user terminal 300 when the charging cable 51 of the electric vehicle 5 is inserted into the outlet 100, and recognizes the outlet ID with the recognized user terminal 300. Can transmit

Next, the user terminal 300 transmits the received outlet ID, charging information, and the user ID to the management server 200 (S30).

The charging information may include at least one of a charging time and a charging amount input from a user, and the charging time may be set as information such as a charging start time and a charging end time. The user ID may include user's unique number, vehicle number, communication socket information, or the like as information for identifying the user.

Next, the management server 200 approves charging for the user terminal 300 based on the outlet ID, the charging information, and the user ID (S40).

The management server 200 determines whether the charging request of the user terminal 300 is a legitimate user's charging request based on the user ID, and determines whether charging using the outlet 100 corresponding to the outlet ID is possible based on the charging information. Can be approved. Although not shown in FIG. 1, when charging is approved, the management server 200 may charge the charging fee based on the charging information, and provide the user terminal 300 with a result of charging the charging fee.

When the management server 200 approves the charging, the management server 200 generates the approval information and transmits the approval information to the user terminal 300 (S50). The approval information may have a form previously promised between the outlet 100 and the management server 200.

Next, when the approval information is received from the management server 200, the user terminal 300 transmits the charging information and the approval information to the outlet 100 (S60).

Next, the outlet 100 supplies power to the electric vehicle 5 based on the approval information received from the user terminal 300 (S72). According to one embodiment, the outlet 100 confirms the connection of the charging cable 51 of the electric vehicle 5 and charges the electric vehicle 5 through the charging cable 51 connected at the charging start time based on the charging time. Can supply power. The outlet 100 blocks the charging power of the system 1 when the actual charging time or the charging amount reaches the charging time or the charging amount included in the charging information received from the user terminal 300 (S74). According to one embodiment, the outlet 100 may cut off the charging power supplied to the electric vehicle 5 at the end time of charging based on the charging time.

Next, when the user terminal 300 is recognized by the user again to the outlet 100 (S76), the outlet 100 transmits the outlet ID and the charging result to the recognized user terminal 300 (S80). The charging result may mean an actual charging time or an actual charging amount, and may include at least one of a first charging time and a first charging amount from charging power supply to shutting off the charging power.

Next, the user terminal 300 transmits the received outlet ID, the charging result, and the user ID to the management server 200 (S90).

The management server 200 recognizes that the charging for the outlet 100 having the received outlet ID is terminated, and terminates the charging service for the outlet 100 (S95). In an embodiment, the management server 200 may determine whether the user terminal 300 that has transmitted the charging result is an authorized user in step S40 based on the user ID. In this way, the management server 200 may transmit a message indicating that the charging is terminated to the user terminal 300 corresponding to the user ID when the charging service is terminated.

As can be seen in the above-described embodiment, in the case of the electric vehicle charging service providing method according to the present invention, the outlet 100 communicates with the user terminal 300 in a short range communication method, and the user terminal 300 is interlocked with the outlet 100. In order to communicate with the management server 200, the outlet 100 can transmit and receive data such as an outlet ID and charging information through the user terminal 300 without configuring a separate data communication module, and transmit and receive for data communication. You can also save money.

Meanwhile, although FIG. 1 illustrates that the user performs authentication by recognizing the user terminal 300 to the outlet 100 for charging the electric vehicle, according to the modified embodiment, the user uses the management server through the user terminal 300. Charge reservation may be performed in advance, and the electric vehicle may be charged according to the charge reservation.

In FIG. 1, the electric vehicle charging has been described in the case of normal termination in which the charging time or the charging amount included in the charging information received through the user terminal 300 is terminated. However, the charging is abnormally terminated before the charging is normally terminated. This can happen. For example, a situation may occur in which the charging cable 51 is disconnected from the outlet 100 before charging is normally terminated. Hereinafter, a charging service providing method when the charging cable 51 is disconnected from the outlet 100 before the normal charging ends through FIG. 2 will be described.

2 is a flowchart illustrating a charging service providing method according to an exemplary embodiment of the present invention when the charging cable is disconnected from the outlet before normal charging ends.

Since the process until the charging is started is the same as S10 to S60 shown in FIG. 1, a detailed description thereof will be omitted.

After the charging power supply described in S72, when the charging cable 51 is disconnected from the outlet 100, the outlet 100 cuts off the charging power supplied to the electric vehicle 5 (S74).

As described above, the outlet 100 according to the embodiment of the present invention is connected to another user (hereinafter referred to as "another user") whose charging cable 51 is an arbitrary or unjustified user of an authorized user during charging. When disconnected from the system (1) by disconnecting the power to keep the power off when connecting the charging cable of other users, and maintains the power off even when reconnecting the charging cable 51 of the user with the right authority do. In this case, after the other user is forcibly disconnecting the charging cable 51 of the user who has a legitimate authority, the electric vehicle charging cable may be connected to the outlet 100 to prevent the conducting behavior of charging the electric vehicle. .

When the charging cable 51 is disconnected by the user with the right authority, the outlet 100 transmits the outlet ID and the charging result to the user terminal 300 of the user with the right authority, and the user terminal 300 is S80. The outlet ID, the charging result, and the user ID received from the transmission are transmitted to the management server 200 (S90). The charging result may mean an actual charging time or an actual charging amount, and may include at least one of a second charging time and a second charging amount from the charging power supply to the separation of the charging cable 51.

On the other hand, when the charging cable 51 of the user having a legitimate authority by the other user is disconnected and another user recognizes the other user terminal 400 which is his terminal to the outlet 100 in order to charge his electric vehicle ( S76), the outlet 100 transmits the outlet ID and the charging result to the recognized other user terminal 400 (S80). At this time, in step S80, the charging result of the legitimate user whose charging cable 51 is separated is transmitted. The other user terminal 400 transmits the outlet ID, the charging result, and the other user ID received at S80 to the management server 200 (S90). In this case, the other user terminal 300 may transmit other charging information together as charging information for charging the electric vehicle of another user.

Next, the management server 200 determines whether the charging of the electric vehicle 5 is normally terminated (S100). In one embodiment, the management server 200 is charged if the second charging time or the second charging amount included in the charging result is different from the charging time or the charging amount included in the charging information received from the user terminal 300 in step S30 It may be determined that the abnormal termination has ended, and if it is the same, the charging may be determined to have ended normally.

If it is determined that the charging is abnormally terminated, the management server 200 refunds the charging fee for the user terminal 300 based on the actual charging time or the actual charging amount (S110). The management server 200 corresponds to the difference between the charging amount corresponding to the difference between the charging time included in the charging information and the second charging time included in the charging result, or the difference between the charging amount included in the charging information and the second charging amount included in the charging result. You can refund the charge. At this time, the management server 200 informs the user terminal 300 of the legitimate user to resume charging by abnormal charging termination and the charging time allocated to the user terminal 300 so that the user resumes the charging procedure. You can do that.

In one embodiment, the management server 200 may determine that the user is another user without a legitimate authority based on the other user ID received from the other user terminal 400 in S90, and may disapprove the charging of the other user. have. Accordingly, it is possible to prevent the damage of the legitimate user by disapproving the charging of another user who does not have the legitimate authority during the charging time assigned to the legitimate user.

On the other hand, when it is determined in step S100 that the management server 200 is determined that the charging is normally terminated, the charging service for the user terminal 300 ends (S120). In addition, although FIG. 2 illustrates a case in which another user disconnects the charging cable 51 from the outlet 100 and recognizes the other user terminal 400 in the outlet 100, a user with a legitimate authority is based on the charging time. The charging cable 51 may be disconnected from the outlet 100 and the user terminal 300 may be recognized by the outlet 100 before the end of the charging time. In this case, the management server 200 may process that the charging time allocated to the user terminal 300 has ended so that other users can perform the electric vehicle charging even before the charging end time allocated to the user terminal 300. have.

Hereinafter, a charging service providing method when a plurality of outlets 100 are arranged in one distribution board will be described with reference to FIG. 3. Repeated descriptions of contents overlapping with those described in FIG. 1 will be omitted.

Referring to FIG. 3, when the user terminal 300 is recognized in any one outlet (100, hereinafter referred to as a "target outlet") of the outlet 100 included in the distribution panel (S210), the target outlet 100 is an outlet The ID is transmitted to the recognized user terminal 300 (S220). The outlet ID is used by the management server 200 to identify the target outlet 100.

Next, the user terminal 300 transmits the received outlet ID, charging information, and the user ID to the management server 200 (S230).

Next, the management server 200 identifies an outlet group to which the outlet ID belongs among outlet groups set for each distribution board (S241). At this time, each outlet group is composed of outlets connected to one distribution panel.

The management server 200 determines whether charging of the target outlet 100 is possible according to whether other outlets included in the identified outlet group are charged (S242). Determining whether the target outlet 100 can be charged based on whether other outlets included in the outlet group identified in the present invention can be charged is that the outlets included in the same outlet group are branched from one distribution panel and one distribution panel. This is because a problem may occur when charging is performed at the same number of outlets simultaneously because the allowable current is limited.

In one embodiment, the management server 200 may determine that the reservation for the target outlet 100 is impossible if the number of outlets being charged among other outlets included in the identified outlet group is greater than or equal to the reference number.

In the above-described embodiment, it has been described that the management server 200 determines whether the charging is possible based on a result of comparing the number of outlets being charged with the reference number. However, in another embodiment, the management server 200 identifies the outlet group identified. It may be determined whether charging is possible based on the allowable current of the connected distribution panel.

If it is determined that charging is impossible (S242), the management server 200 terminates the charging service while guiding that charging is impossible (S243).

On the other hand, if it is determined that the charging is possible, the management server 200 approves charging for the corresponding user terminal 300 based on the user ID (S244), and transmits the approval information to the user terminal 300. (S250).

Subsequent processes are the same as S60 to S95 illustrated in FIG. 1, so a detailed description thereof will be omitted.

In FIG. 3, the charging service of the EV charging system managing the plurality of outlets as a group is terminated normally. However, in the embodiment of managing the plurality of outlets as a group, charging is abnormally terminated. It can operate as described above.

Meanwhile, in FIG. 3, when the other outlets 100 included in one distribution panel are being charged, the charging service is terminated by disabling charging of the target outlet 100. However, in the modified embodiment, when charging is not possible, the management server 200 may provide a reservation service.

Hereinafter, the charge reservation service will be described with reference to FIG. 4. 4 is a flowchart illustrating an electric vehicle charging reservation service method according to an exemplary embodiment of the present invention.

The user terminal 300 transmits the charging reservation information including the outlet ID and the target reservation time of the target outlet 100 to be charged reservation target to the management server 200 (S246). The management server 200 identifies an outlet group to which the outlet ID belongs among outlet groups set for each distribution board (S247).

The management server 200 determines whether a reservation is possible for the target outlet 100 corresponding to the received outlet ID (S248).

In one embodiment, the management server 200 determines that the reservation is impossible if the pre-reservation time set for the target outlet 100 and the target reservation time overlap each other.

If the pre-booking time and the target reservation time do not overlap, the management server 200 is a target outlet 100 if the number of outlets that the reservation time overlaps the target reservation time among the other outlets of the outlet group including the target outlet is more than the reference number ) Reservations are not possible.

As a result of the determination of step S248, if it is determined that the reservation is not possible, the management server 200 may inform that the reservation is impossible, and may terminate the reservation service or guide the time when the reservation is possible.

On the other hand, if it is determined in step S248 that the reservation is possible, the management server 200 approves the reservation for the corresponding user terminal 300 based on the user ID (S249), and the reservation approval information to the user terminal 300. Transmit (S250).

Next, the user terminal 300 transmits the received reservation approval information and reservation information to the target outlet 100 (S260). At this time, the user should connect the charging cable of his electric vehicle to the target outlet in advance.

Next, the outlet 100 supplies the charging power to the electric vehicle 5 through the connected charging cable 51 at the reservation start time included in the received reservation information (S272). The outlet 100 may supply charging power to the charging cable 51 of the electric vehicle 5 approved by the management server 200 based on the received approval information.

Next, the outlet 100 cuts off the charging power supplied to the electric vehicle 5 at the reservation end time including the reservation information (S274).

Next, when the user terminal 300 is recognized again (S276), the outlet 100 transmits the outlet ID and the charging result to the recognized user terminal 300 (S280).

Next, the user terminal 300 transmits the received outlet ID, the charging result, and the user ID to the management server 200 (S290).

The management server 200 recognizes that the charging for the outlet 100 having the outlet ID is terminated, and terminates the charging service for the outlet 100 (S300).
