The controller 120 according to an exemplary embodiment of the present invention checks the first attribute value of one or more time slots included in the charge time table, and identifies one or more time slots whose first attribute value is a value corresponding to the chargeable state, Can be detected.

In the present invention, the charging time table may mean a schedule in which electric vehicles to be charged by the electric vehicle charging and scheduling device 10 are recorded in each time slot. Thus the charge time table may include information about how many electric cars connected to the port several times in each time zone should be charged. The charge time table may also include information as to when the charge can be made, that is, at what time zone there is no electric car reserved for charging.

For example, the charge time table may include information about charge reservations of an electric car connected to port 2 from 16:00 on May 12, 2016 to 17:00 on May 12, 2016.

In the present invention, the time slot is a time unit constituting the time table described above, and may be a standard unit of all operations of the electric vehicle charge scheduling apparatus 10. [ For example, the size of the type slot may be 10 minutes, so that the electric vehicle charging and scheduling apparatus 10 can use 10 minutes as a unit time for charge reservation, charging progress, and charging of the electric vehicle 20 have. More specifically, the user can reserve the charge time in units of 10 minutes, and the electric vehicle charge scheduling apparatus 10 can charge the charge in units of 10 minutes (for example, 20 minutes, 50 minutes and 180 minutes) The scheduling device 10 can calculate the charge amount based on the amount per 10 minutes. The size of the timeslot may be set by the manager of the electric vehicle charge scheduling apparatus 10. [ For example, the size of a timeslot may be 1 second or 30 minutes.

3 is a diagram illustrating a charge time table and a time slot.

As described above, the charging time table 121 may include a plurality of time slots. The charge time table 122 may include a plurality of time slots 1221 to 1226. The charge time table 122 may include a plurality of time slots 1221 to 1226. [ Of course, this is an example when the size of the time slot is " 10 minutes ", and in the case where the size of the time slot is different, the number may be different.

Meanwhile, a charge time table including a plurality of time slots can be constructed in the memory 130 in the form of a database. For example, the time table may be a database having 'time', 'first attribute value' and 'second attribute value' as fields. In this case, the time slot may correspond to one record having a specific value for each field. For example, a timeslot may have a value of "Time" field of "201605121610-201605121620", with a first attribute value of "1" and a second attribute value of NULL, starting from 16:10 on May 12, 2016 to 2016 It may be a record corresponding to 16:20 on May 12.

Of course, the above-described configuration of the charging time table and the time slot is illustrative, and the spirit of the present invention is not limited thereto.

In the present invention, the 'value corresponding to the chargeable state' can be set by the user. For example, as in the above-described example, if the charge time table is constructed in the database and one time slot corresponds to one record, the value corresponding to the chargeable state may be "1 ". In other words, the controller 120 can detect a time slot corresponding to a record including a value "1 " indicating a chargeable state in the 'first attribute value' field as a chargeable time slot. Of course, the above-mentioned "1" is an example, and "possible"

On the other hand, the value corresponding to the non-chargeable state may be "0 ". Of course, it is obvious that "impossible "," not_available "

Accordingly, the controller 120 checks the first attribute value of one or more time slots constituting the charge time table, and if the time slot having the value corresponding to the chargeable state is detected as the chargeable time slot by the first attribute value can do.

The controller 120 may provide the charging information including the chargeable time slot corresponding to the chargeable time slot and the charge amount per slot of the chargeable time slot to the user.

As described above, since each time slot may include 'time', 'first attribute value', and 'second attribute value', the controller 120 may determine 'time' included in the detected chargeable time slot, , It is possible to provide information on the chargeable time zone to the user.

4 is a diagram for explaining the chargeable time zone in more detail.

The charging time table can be constructed, for example, in the form of a database. However, for convenience of description, the charge time table is illustrated in the form of a graph as shown in FIGS. 3 and 4.

3, it is assumed that the size of the time slot is '10 minutes', that six time slots are included at one time, and that the time slot having a value corresponding to the non-chargeable state is colored with the first attribute value do.

In this case, the chargeable time zone may be a time zone corresponding to the T2 zone and the T4 zone on the graph. Of course, the time zone corresponding to each of the T1 zone, the T3 zone and the T5 zone may be a time zone in which charging is impossible.

The control unit 120 may provide the user with information on the time zone corresponding to the interval T2 and the interval T4 described above so that the user can select a time for charging the electric vehicle.

Meanwhile, the control unit 120 may display information on the chargeable time zone through the display unit 110, thereby providing the user with information on the chargeable time zone. At this time, the controller 120 may provide information in the form of a graph as shown in FIG. 4, or may provide information in the form of text such as "14: 30-16: 00: have.

The control unit 120 may provide information on the rechargeable time slot and may provide the user with information regarding the recharged amount of each rechargeable time slot. At this time, the control unit 120 may determine the charge amount per slot of the chargeable time slot according to various criteria.

For example, the control unit 120 checks the connection time point at which the connection information of the electric vehicle 20 is received, and determines whether the time difference between any one of the time points included in the time point corresponding to the connection time point and the time slot is shorter It can be determined that the charging amount per slot is high. According to this, the charging amount per slot is higher in the time slot belonging to the earliest time slot in the chargeable time slot. On the contrary, the charging amount per slot is lower in the time slot belonging to the later time zone of the chargeable time slot.

That is, according to the present invention, the user can charge a high amount for fast charging or a low amount for late charging. Thus, the present invention makes it possible to use the system more efficiently by distributing the usage time of the user in the charging system of limited charging performance with the limitation of the number of concurrent users. Further, the manager of the electric vehicle charge scheduling apparatus 10 can maximize the profit by setting a high charge for fast charge, and the owner of the electric car can spend the low cost for the slow charge, It can be charged.

On the other hand, the control unit 120 receives the charging information including the information on the electricity billing amount by time from the external device (not shown), refers to the received charging information, Of the total amount of the electricity bill.

For example, when the electricity billing amount per unit time from 1:00 am to 6:00 am is lower than the electricity billing amount in the other time zones by using the nighttime electricity or the like, the control unit 120 determines that the time belonging to the above- It is possible to inexpensively determine the charge amount per time slot for a slot as compared with a time slot belonging to another time slot. That is, the control unit 120 can determine the charge amount per slot of the time slots belonging to the period from 1:00 am to 6:00 am to be equal to or greater than the sum of the fee amount per charge per charge per unit time from 1:00 am to 6:00 am .

Thus, the present invention can more actively determine the amount of charge according to the change of the electricity billing solution according to the time zone.

FIG. 5 shows a screen 111 in which charge information is displayed on the display unit 110 according to an embodiment of the present invention.

Referring to FIG. 5, the screen 111 may include user information 112, charging information 113, billing amount information 114, current time 115, and summary information 116.

The user information 112 may be part of the information received from the electric vehicle 20. For example, the user information 112 may include 'car number', 'connection port', 'user name', and 'payment information'. However, it should be understood that the present invention is not limited thereto. Therefore, the user information 112 may further include a current charge level of the vehicle.

The charging information 113 may include information on charging information provided by the control unit 120, that is, information on a chargeable time zone and a charge amount per time slot. At this time, as described above, the charge controller 120 may provide charge information in the form of a graph.

The controller 120 according to an exemplary embodiment may acquire information about a desired charging time zone of a user selected by the user and may extract a selected time slot corresponding to a desired charging time slot.

For example, when the controller 120 provides the charging information in the form of a graph as shown in FIG. 5, the user can input a desired charging time zone by selecting one section of the graph. For example, the user can input the time from 14:40 to 15:40 belonging to the chargeable time zone as the desired charge time. In response to this input, the controller 120 can extract six time slots corresponding to the desired charging time period as selected time slots.

Then, the controller 120 may update the first attribute value of the selected time slot to a value corresponding to the non-chargeable state, and update the second attribute value of the selected time slot with the identification information of the user. Thus, the control unit 120 can charge the electric car of the user. On the other hand, the 'value corresponding to the non-chargeable state' may be a value set by the user such as '0', 'impossible' or 'not_available' as described above. The method by which the control unit 120 obtains the second attribute value will be described later.

The controller 120 may receive connection information including identification information of the electric vehicle from an electric vehicle connected to any one of the charging ports. At this time, the identification information of the electric vehicle may include a Vehicle Identification Number (VIN) and a vehicle number. Furthermore, the connection information may further include, in addition to the above-described identification information, connected port information, a user name, remaining battery capacity of the electric vehicle, and information regarding the payment means.

Since the connection unit 140 connecting the electric vehicle charging and scheduling apparatus 10 and the electric vehicle 20 includes means for enabling mutual data communication in addition to means capable of transmitting electric power as described above, May receive various information from the electric vehicle 20 in addition to the items listed above.

The controller 120 may refer to the information received from the electric vehicle 20 and update the second attribute value of the selected time slot corresponding to the desired charging time slot of the user with the identification information of the user. In other words, the control unit 120 may include the identification information of the electric vehicle of the user in the second attribute value of the time slot corresponding to the desired charging time slot.

Meanwhile, the connection information of the control unit 120 may be received at any stage before the actual charging of the electric vehicle is started. For example, reception of the connection information of the control unit 120 may be performed before detecting the chargeable time slot. Also, the reception of the connection information of the controller 120 may be performed when updating the second attribute value of the selected time slot with the identification information of the user.

The controller 120 refers to the first attribute value, the second attribute value, and the connection information of each time slot to determine whether the electric power corresponding to the second attribute value in the time slot corresponding to each time slot Can be supplied.

The electric vehicle charge scheduling apparatus 10 according to the present invention may include a timer and / or a counter, and the controller 120 may acquire information on the current time from the timer and / or the counter can do. The controller 120 refers to the acquired information about the current time, the first attribute value of the time slot corresponding to the current time, and the second attribute value of the time slot corresponding to the current time to charge one or more electric vehicles 20 Charging can be done according to the time table.

Specifically, when the first attribute value of the timeslot corresponding to the current time is a value corresponding to the non-chargeable state, and the second attribute value is identification information of the electric vehicle, the control unit 120 refers to the second attribute value, It is possible to supply power to the port to which the electric vehicle corresponding to the identification information of the vehicle is connected.

On the other hand, the controller 120 can measure the power supply time through each port. Also, the controller 120 can determine the charge amount for the user by referring to the information on the power supply time and the charge amount per time slot.

For example, the control unit 120 may determine the charge amount as a product of the actual charge time in the corresponding time slot with the charge amount per time slot. Thus, even if the user disconnects the electric vehicle 20 from the electric vehicle charge scheduling device 10 during charging, the electric vehicle 20 can be charged for the charge time of the electric vehicle 20.

6 is a flowchart for explaining an electric vehicle charge scheduling method performed by the electric vehicle charge scheduling apparatus 10. In FIG. Hereinafter, the detailed description of the contents overlapping with those described in Figs. 1 to 5 will be omitted.

Furthermore, the connection information may further include, in addition to the above-described identification information, connected port information, a user name, remaining battery capacity of the electric vehicle, and information regarding the payment means.

In this flowchart, reception of the connection information of the control unit 120 is shown as the first step. However, the reception of the connection information of the control unit 120 may be performed at any stage before the actual charging of the electric vehicle is started . Accordingly, the connection information of the controller 120 may be received before the rechargeable time slot is detected, or may be updated when the second attribute value of the selected time slot is updated with the identification information of the user.

The controller 120 according to an exemplary embodiment of the present invention checks the first attribute value of one or more time slots included in the charge time table, and identifies one or more time slots whose first attribute value is a value corresponding to the chargeable state, (S61). Since the charging time table and the time slot are as described above, a detailed description thereof will be omitted. It has also been described above that the charge time table can be constructed, for example, in the form of a database.

The controller 120 may provide the charging information including information on the chargeable time slot corresponding to the chargeable time slot and the charge amount per slot of the chargeable time slot to the user. As described above, since each time slot may include 'time', 'first attribute value', and 'second attribute value', the controller 120 may store 'time' included in the detected chargeable time slot , It is possible to provide the user with information on the chargeable time zone.

Meanwhile, the control unit 120 may display information on the chargeable time zone through the display unit 110, thereby providing the user with information on the chargeable time zone. At this time, the controller 120 may provide information in the form of a graph as shown in FIG. 4, or may provide information in the form of text such as "14: 30-16: 00: have.

In addition, the controller 120 may provide information on the chargeable time slot and may provide the user with information about the charge amount per slot of the chargeable time slot.

(S64) This allows the control unit 120 to make a charging reservation of the electric vehicle of the user.

The controller 120 refers to the first attribute value, the second attribute value, and the connection information of each time slot to determine whether the electric power corresponding to the second attribute value in the time slot corresponding to each time slot (S65). Specifically, when the first attribute value of the time slot corresponding to the current time corresponds to the charge disable state and the second attribute value is identification information of the electric vehicle, It is possible to supply power to the port to which the electric vehicle corresponding to the identification information of the electric vehicle is connected by referring to the second attribute value.

The control unit 120 according to an exemplary embodiment may measure the time at which power is supplied through each port. (S66) The controller 120 also refers to the information about the power supply time and the charging amount per time slot (S67). For example, the controller 120 may determine the charge amount as a product of the time of actual charge in the corresponding time slot and the charge amount of each time slot. Thus, even if the user disconnects the electric vehicle 20 from the electric vehicle charge scheduling device 10 during charging, the electric vehicle 20 can be charged for the charge time of the electric vehicle 20.

The electric vehicle charging scheduling method according to an embodiment of the present invention can be implemented as a computer-readable code on a computer-readable recording medium.
