[0049] <Charging record management DB206> 8 is an explanatory diagram showing an example of the charging record management DB 206. The charging record management DB 206 is a table for managing the charging record by the charger 126. The charging record management DB 206 has, as fields, a user ID 502, a reservation ID 501, a record ID 601, a total payment amount 801, a charging unit price at the time of payment 802, and a charging unit price operation factor ID 803. A combination of values ​​of the respective fields in the same row becomes an entry that specifies one charging record.

[0050] The total payment amount 801 is the charging fee paid by the user 240 identified by the user ID 502. Specifically, for example, the total payment amount=charging time×charging unit price at time of payment. The charging time is the time from the charging start time 604 to the charging end time 605.

[0051] The charging unit price at payment 802 is the charging unit price 445 when the total payment amount 801 is paid. The time when the total payment amount 801 is paid is, for example, the charging end time 605.

[0052] The charging price operation factor ID 803 is identification information that uniquely identifies the charging price operation factor. The charging price operation factor is a factor that operates (increases or decreases) the charging price. Specifically, for example, the charging price operation factor is a factor for operating the reference electricity price 1001 (described later) based on the operation status of the charger 126 installed in the parking lot 102. The charging price varies depending on the charging price operation factor.

[0053] <Charging unit price operation factor DB207> 9 is an explanatory diagram showing an example of the charging unit price operation factor DB207. The charging unit price operation factor DB207 is a table that specifies charging unit price operation factors. The charging unit price operation factor DB207 has fields including a charging unit price operation factor ID 803, an event 901, and a weight 902. A combination of values ​​in each field in the same row becomes an entry that specifies one unit price increase factor.

[0054] The event 901 is the cause of the occurrence of a charging unit price operation factor identified by the charging unit price operation factor ID 804 .

[0055] The weight 902 is a coefficient for varying the charging price 445 with the charging price operation factor specified by the charging price operation factor ID 804 .

[0056] <Charging Fee Calculation DB208> 10 is an explanatory diagram showing an example of the charging fee calculation DB 208. The charging fee calculation DB 208 has, as fields, a parking lot ID 401, a reference electricity unit price 1001, a minimum price 1002, a maximum price 1003, an applied charging unit price operation factor ID 1004, and a new charging unit price 1005.

[0057] The standard electricity unit price 1001 is the standard electricity unit price in the parking lot 102 .

[0058] The minimum price 1002 is the lower limit of the charging price 445 .

[0059] The maximum price 1003 is the upper limit of the charging price 445.

[0060] The applied charging unit price operation factor ID 1004 is the charging unit price operation factor ID 803 applied in the parking lot 102 .

[0061] The new charging unit price 1005 is the charging unit price 445 after the operation based on the applied charging unit price operation factor ID 1004. The new charging unit price 1005 is a result of multiplying the reference power unit price 1001 by each weight 902 of the applied charging unit price operation factor ID 1004.

[0062] For example, in the case of an entry in which the parking lot ID 401 is "P1", the applicable charging unit price operation factor ID 1004 is only "UF3". The weight 902 of "UF3" is "1.1". Therefore, the new charging unit price 1005 of "P1" is 15 [yen / kWh] x 1.1 = 16.5 [yen / kWh].

[0063] For an entry in which the parking lot ID 401 is "P2", the applied charging unit price operation factor ID 1004 is "UF1" and "UF3". The weight 902 of "UF1" is "1.3". Therefore, the new charging unit price 1005 of "P2" is 15 [yen / kWh] x 1.3 x 1.1 = 21.5 [yen / kWh].

[0064] <Operation example 1 of edge device 121> 11 is a flowchart showing a first operation example of the edge device 121. FIG. 11 shows an operation example of the edge device 121 when the electric vehicle 101 enters the parking lot 102.

[0085] (Step S1106) The edge device 121 transmits the vehicle ID 503, the unlocking flag, the exit time 603, the parking space ID 441, the charger ID 443, and the parking lot ID 401, which are matched in steps S1401 and S1405, as exit data to the charging management server 201. The exit time 603 is registered as record information 600 in the entry / exit record DB 204.

[0086] <Operation Example 1 of the Charging Management Server 201> FIG. 15 is a flowchart showing a first operation example of the charge managing server 201.

[0087] (Step S1501) The charging management server 201 acquires reservation status data from the reservation server 250. The reservation status data includes a parking lot ID 401, a reservation ID 501, a user ID 502, a vehicle ID 503, a reservation start time 504, a reservation end time 505, a previous location 506, a next location 507, and a predicted electricity consumption 508.

[0088] (Step S1502) The charging management server 201 registers the acquired reservation status data in the reservation information DB 203 .

[0089] <Operation Example 2 of Charging Management Server 201> FIG. 16 is a flowchart showing a second operation example of the charging management server 201.

[0090] (Step S1601) The charging management server 201 waits for reception of the storage data in step S1606. If the storage data is not received (step S1601: No), the process proceeds to END. If the storage data is received (step S1601: Yes), the process proceeds to step S1602.

[0091] (Step S1602) The charging management server 201 assigns a record ID 601 to the received storage data, and adds an entry to the storage / delivery record DB 204 .

[0092] (Step S1603) The charging management server 201 acquires the user ID 502 and the reservation ID 501 corresponding to the vehicle ID 503 from the reservation information DB 203 , and adds them to the entry of the entry / retrieval record DB 204 as an acquired user ID 606 and an acquired vehicle ID 607 .

[0093] (Step S1604) The charging management server 201 waits for reception of the charging start data in step S1203. If the charging start data is not received (step S1604: No), the process proceeds to END. If the charging start data is received (step S1604: Yes), the process proceeds to step S1605.

[0094] (Step S1605) The charging management server 201 adds the charging start time 604 to an entry in the entry / withdrawal record DB 204. Specifically, for example, the charging management server 201 identifies the parking space ID 441 corresponding to the charger ID 443 in the charging start data, identifies an entry in which the identified parking space ID 441 is located from the entry / withdrawal record DB 204, and adds the charging start time 604 to the identified entry.

[0095] (Step S1606) The charging management server 201 identifies an entry in the charger operation information DB 205 and updates the operation status 702. Specifically, for example, the charging management server 201 identifies the charger operation information 700 in the charger operation information DB 205 from the parking lot ID 401 of the charging start data, identifies the entry of the charger ID 443 of the charging start data from the charger operation information 700, and updates the operation status 702 from "0" to "1". The charging management server 201 also calculates and updates the remaining charging time 703. The remaining charging time 703 is set to the time from the current time to the reservation end time 505 of the electric vehicle 101 being charged by the charger 126, and decreases as time passes.

[0096] (Step S1607) The charging management server 201 waits for reception of the charging end data in step S1303. If the charging end data is not received (step S1607: No), the process proceeds to END. If the charging end data is received (step S1607: Yes), the process proceeds to step S1608.

[0097] (Step S1608) The charging management server 201 adds the charging end time 605 to an entry in the entry / unloading record DB 204. Specifically, for example, the charging management server 201 identifies the parking space ID 441 corresponding to the charger ID 443 in the charging end data, identifies an entry in which the identified parking space ID 441 is located from the entry / unloading record DB 204, and adds the charging end time 605 to the identified entry.

[0098] (Step S1609) The charging management server 201 identifies an entry in the charger operation information DB 205 and updates the operation status 702. Specifically, for example, the charging management server 201 identifies the charger operation information 700 in the charger operation information DB 205 from the parking lot ID 401 of the charging end data, identifies the entry of the charger ID 443 of the charging end data from the charger operation information 700, and updates the operation status 702 from "1" to "0." In addition, the charging management server 201 resets the remaining charging time 703 to 0.

[0099] If the remaining charging time 703 becomes 0 before receiving the charging end data, the charging management server 201 may instruct the edge device 121 that controls the charger 126 to end charging.

[0100] (Step S1610) The charge management server 201 waits for reception of the delivery data in step S1406. If the delivery data is not received (step S1610: No), the process proceeds to END. If the delivery data is received (step S1610: Yes), the process proceeds to step S1611.

[0101] (Step S1611) The charging management server 201 identifies an entry in the parking entry / exit record DB 204 from the parking space ID 441 included in the received exit data, and registers the exit time 603 .

[0102] <Charging unit price calculation process> FIG. 17 is a flowchart showing an example of a charging price calculation process performed by the charging management server 201.

[0103] (Step S1701) The charging management server 201 acquires the reservation information 500 from the reservation information DB 203 .

[0104] (Step S1702) The charging management server 201 identifies a parking lot subject to charging price manipulation from the reservation information 500 and the delivery route plan. The delivery route plan is acquired from the reservation server 250. The delivery route plan is plan data indicating a delivery route of the electric vehicle 101, and includes, for example, the route 100 shown in FIG. 1 and the vehicle ID 503 and user ID 502 of the electric vehicle 101 traveling on the route 100.

[0105] The charging management server 201 identifies the position information 402 of the waypoint P4 where the parking lot 102 is located on the route 100 from the parking lot DB 202, and identifies the parking lot 102 at the waypoint P4 as a parking lot subject to charging price manipulation. Note that the charging management server 201 may also identify parking lots 102 located within a predetermined distance from each of the points P1 to P5 on the route 100 as parking lots subject to charging price manipulation.

[0106] (Step S1703) The charging management server 201 acquires the reference electricity unit price 1001 corresponding to the parking lot ID 401 of the parking lot that is the target of charging price manipulation from the charging fee calculation DB 208.

[0107] (Step S1704) The charging management server 201 judges whether there is a parking lot ID 401 of an unselected charging price operation target parking lot. If there is a parking lot ID 401 of an unselected charging price operation target parking lot (step S1704: Yes), the process proceeds to step S1705. If there is no parking lot ID 401 of an unselected charging price operation target parking lot (step S1704: No), the process proceeds to END.

[0108] (Step S1705) The charging management server 201 refers to the charging unit price operation factor DB 207 and accepts the selection of the charging price operation factor. Specifically, for example, the charging management server 201 displays the charging unit price operation factor ID 803, the event 901, and the weight 902 of the charging unit price operation factor DB 207 on a display screen and waits for a selection from the user. When the selection from the user is accepted, the process proceeds to step S1706.

[0109] (Step S1706) The charging management server 201 calculates a new charging price 1005 by multiplying the reference electricity price 1001 by the weight 902 of the selected charging price operation factor.

[0110] (Step S1707) The charging management server 201 judges whether the new charging unit price 1005 is between the minimum price 1002 and the maximum price 1003. If the new charging unit price 1005 is not between the minimum price 1002 and the maximum price 1003 (step S1707: No), the process returns to step S1705. If the new charging unit price 1005 is between the minimum price 1002 and the maximum price 1003 (step S1707: Yes), the process proceeds to step S1708.

[0111] (Step S1708) The charging management server 201 outputs the new charging price 1005 in a displayable manner.

[0112] (Step S1709) The charging management server 201 updates the new charging unit price 1005 in the charging fee calculation DB 208, and returns to step S1704.

[0113] Specifically, for example, the charging management server 201 overwrites the new charging unit price 1005 to the charging price 445 of the charger ID 443. As a result, the new charging unit price 1005 is reflected in the charger 126.

[0114] <Electricity cost calculation process> FIG. 18 is a flowchart showing an example of a procedure of a power cost calculation process performed by the charging management server 201.

[0115] (Step S1801) The charging management server 201 judges whether or not there is an unselected record ID 601. If there is no unselected record ID 601 (step S1801: No), the process returns to step S1801. If there is an unselected record ID 601 (step S1801: Yes), the process proceeds to step S1802.

[0116] (Step S1802) The charging management server 201 selects an entry of an unselected record ID 601 from the incoming / outgoing record DB 204 .

[0117] (Step S1803) The charging management server 201 acquires the cruising distance (the distance from the parking lot 102 to the next point 507). The charging management server 201 calculates the cruising distance based on the position information 402 of the parking lot 102 and the position information on the map of the next point 507. The charging management server 201 may acquire the distance by accessing a map server (not shown) capable of calculating the distance between two points.

[0118] (Step S1804) The charging management server 201 acquires the battery capacity at the time of leaving the depot. Specifically, for example, the battery capacity at the time of leaving the depot is calculated by the rated output of the charger x the charging time. For example, in the entry with the actual ID 601 of "a41" shown in Fig. 6, since the charging time (charging end time 605-charging start time 604) is 48 minutes, if the charging output 444 is rated at 50 kW, then 50 x 48 ÷ 60 = 40 kW has been charged.

[0119] (Step S1805) The charging management server 201 calculates the electricity cost. Specifically, for example, the charging management server 201 calculates the electricity cost by dividing the cruising distance by the battery capacity at the time of departure.

[0120] (Step S1806) The charging management server 201 determines whether the difference between the estimated and actual electricity consumption is within an acceptable range. Specifically, for example, the charging management server 201 determines whether the difference between the electricity consumption calculated in step S1805 and the estimated electricity consumption 508 is within an acceptable range. If it is within the acceptable range (step S1806: Yes), the charging management server 201 proceeds to step S1807. If it is not within the acceptable range (step S1806: No), the charging management server 201 proceeds to step S1808.

[0121] (Step S1806) The charging management server 201 outputs information indicating that there is no effect on the electricity cost in a displayable manner together with the electricity cost.

[0122] (Step S1807) The charging management server 201 outputs information indicating that there is an impact on the electricity cost in a displayable manner together with the electricity cost.

[0123] In this way, according to this embodiment, the charging price 446 of the charger 126 can be manipulated depending on the operation status. Therefore, since the charging price 446 varies depending on the parking lot 102, the user can be guided to a parking lot 102 with a low charging price 446 by setting a route that passes through a point with a low charging price 446, for example.
