Abstract

In the event of a connection error between the electric vehicle and the charger, the system will provide recalculation of the charging and delivery plans. [Solution] The information processing method, based on the operation plan for multiple electric mobile units, assigns a charger to each of the multiple electric mobile units and generates a charging plan for each of the multiple electric mobile units. It obtains a first connection state with the charger for each of the multiple electric mobile units indicated by the charging plan and a second connection state with the charger for each of the multiple electric mobile units that are connected. If the first connection state and the second connection state are different, it replans the operation plan and the charging plan based on the connection state between the electric mobile unit and the charger indicated by the second connection state.

Description

【Technical Field】 【0001】 The present disclosure relates to an information processing method and an information processing apparatus. 【Background Art】 【0002】 Conventionally, a method for creating a charging plan for an electric moving body and a delivery plan for a delivery item has been known. 【0003】 For example, in Patent Document 1, based on constraints related to the movement of a plurality of electric moving bodies, a delivery plan for delivery items by the plurality of electric moving bodies and a charging plan for the plurality of electric moving bodies based on the delivery plan are created, and an information processing method for creating a delivery plan in which the charging of the plurality of electric moving bodies is completed by the start of delivery is disclosed. 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 International Publication No. 2020 / 158073 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 Here, in order to complete the charging of a plurality of electric moving bodies by the start of delivery, it is necessary to correctly connect the vehicle and the charger based on the planned charging plan. However, from the viewpoint that connection errors may occur due to human reasons or the like, there has been room for further improvement in the charging plan and the delivery plan. 【0006】 The present disclosure has been devised in view of the above-described conventional circumstances, and an object thereof is to provide an information processing method and an information processing apparatus for performing a charging plan and a delivery plan. 【Means for Solving the Problems】 【0007】 This disclosure provides an information processing method performed by a management server connected to an electric mobile device and its charger via a network, wherein, based on an operation plan relating to a plurality of electric mobile devices, the management server assigns a charger to each of the plurality of electric mobile devices and generates a charging plan for each of the plurality of electric mobile devices, obtains a first connection state between each of the plurality of electric mobile devices and the charger as indicated by the charging plan, and a second connection state between each of the plurality of electric mobile devices and the charger while connected, and if the first connection state and the second connection state are different, the management server replans the operation plan and the charging plan based on the connection state between the electric mobile device and the charger as indicated by the second connection state. 【0008】 Furthermore, this disclosure relates to an information processing method performed by a computer connected to a management server via a network, wherein the computer generates an operation plan for a plurality of electric mobile units, assigns a charger to each of the plurality of electric mobile units, and if the first connection state between each of the plurality of electric mobile units and the charger, as indicated by the charging plan for charging the electric mobile units, and the second connection state between each of the plurality of electric mobile units and the charger, which is currently connected, the computer generates one or more revised plans, which represent a revised operation plan and a revised charging plan, based on the connection state between the electric mobile unit and the charger, as indicated by the second connection state. The information processing method provides obtaining candidate plan information from the management server, outputting the one or more candidate plan information including changes to the operations of the operator executing the operation plan compared to the operation plan before replanning, outputting the one or more candidate plan information along with information indicating changes to the operations, including at least a change in the combination of the operation area, the electric mobile units assigned to the operation area, and the drivers operating the electric mobile units, accepting the selection of one or more candidate plan information from the one or more candidate plan information, and notifying the management server of the replanning of the operation plan and the charging plan based on the selected candidate plan information. 【0009】 Furthermore, this disclosure provides an information processing device comprising: an operation plan relating to a plurality of electric mobile units; a planning unit that generates, based on the operation plan, an assignment of a charger for charging the electric mobile unit and a charging plan for charging the electric mobile unit for each of the plurality of electric mobile units; and an acquisition unit that acquires, at a time prior to the charging start time, a first connection state between each of the plurality of electric mobile units indicated by the charging plan and the charger, and a second connection state between each of the plurality of electric mobile units that is connected and the charger, wherein if there is an electric mobile unit whose first connection state and second connection state are different, the planning unit replans the operation plan and the charging plan based on the connection state between the electric mobile unit whose first connection state and second connection state are different and the charger.

[Modes for carrying out the invention] 【0012】 The following describes in detail the embodiments of the information processing method and information processing apparatus disclosed herein, with reference to the drawings as appropriate. However, unnecessary details may be omitted. For example, detailed explanations of already well-known matters and redundant explanations of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following explanation and to facilitate understanding by those skilled in the art. The accompanying drawings and the following explanation are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter described in the claims. 【0013】 (Background leading to this disclosure) In recent years, electric vehicles (EVs) (hereinafter simply referred to as "vehicles") have been used for the delivery of goods. Delivery companies using EVs deliver goods during business hours, such as during the day, and fully charge the vehicles at night or outside of business hours in preparation for the next day's delivery work. 【0014】 For example, a conventional information processing method has been disclosed (for example, Patent Document 1: International Publication No. 2020 / 158073) that creates a delivery plan for goods delivered by multiple electric mobile units and a charging plan for multiple electric mobile units based on the delivery plan, based on constraints on the movement of multiple electric mobile units, and creates a delivery plan in which the charging of multiple electric mobile units is completed before the start of delivery. 【0015】 In recent years, due to reasons such as the cost of purchasing chargers and a lack of suitable installation locations, there has been a demand to reduce the number of chargers installed and manage the charging of a large number of vehicles with fewer chargers. Therefore, delivery companies are considering an operation to manage which vehicles need charging and which do not, based on the next day's delivery plan, and to charge vehicles that need charging outside of business hours, such as at night. 【0016】 However, in implementing this operation, if connection errors occur, such as connecting to the wrong charger or connecting to the wrong charger, the delivery company will need to return to the office at night to correct the connection errors. Furthermore, if these connection errors are not resolved, it may become impossible to carry out delivery operations the following day. Therefore, in order to avoid the increased workload required for checking the connection between the vehicle and the charger due to the operation described above, the resulting deterioration of the working environment, and the deterioration of the delivery business's performance, there is a need for a method to check the connection between the vehicle and the charger so that the vehicle is reliably charged outside of business hours. 【0017】 (Background leading to Embodiment 1) Therefore, in the following Embodiment 1, an example of an information display method is described that notifies the drivers of vehicles that need charging that charging is required, in order to connect all vehicles that need charging before this charging starts to the charger, and manages vehicles that need charging outside of business hours and vehicles that do not need charging. 【0018】 (Embodiment 1) First, we will describe some use cases for the charging management system 100 in this disclosure. Figure 1 is a diagram illustrating an example of a use case for the charging management system 100 in this disclosure. Figure 2 is a diagram showing an example of a daily delivery and charging schedule at base A. Figure 3 is a block diagram showing an example of the internal configuration of the charging management system 100 according to Embodiment 1. Note that the charging management system 100 shown in Figures 1 and 3 is just one example and is not limited thereto. 【0019】 A delivery operator, which uses vehicles to deliver goods, must complete the connection process to connect all vehicles requiring charging to the charger before the charging period begins if the vehicles are charged outside of business hours. Therefore, the charging management system 100 in this disclosure determines whether a vehicle returning to the base requires charging. The charging management system 100 also determines whether all vehicles requiring charging are connected to any or designated charger by the deadline for connecting vehicles to the charger (hereinafter referred to as the "charging connection deadline"). The charging management system 100 performs charging management for multiple vehicles managed at the base by notifying the operator of this determination result. 【0020】 The charging connection deadline, as used here, is a time prior to the start of the main charging. For example, in the example shown in Figure 2, the operator performs the main charging of the vehicle during the nighttime period "20:00 to 06:00". In such a case, the charging connection deadline is set to "19:00", which is prior to the start of the main charging. The charging connection deadline and the start time of the main charging can be set arbitrarily. In particular, the charging connection deadline may be set based on the number of vehicles and chargers belonging to base A, taking into account the time required for the operator to reconnect vehicles to chargers to resolve misconnections, or to connect vehicles that are not connected to chargers but require charging, before the start of the main charging. 【0021】 The charging management system 100 manages the charging of vehicles C1 to CN at each location where M (M: an integer of 1 or more) chargers CH1 to CHM are installed, each capable of charging N (N: an integer of 1 or more) EV vehicles C1 to CN. The charging management system 100 includes an integrated management system S1, a vehicle monitoring system S2, a charger management system S3, at least one driver terminal DP1 to DPN, and at least one administrator terminal MP. The number of chargers M and the number of vehicles N may be arbitrary values. 【0022】 The integrated management system S1 is connected via wired or wireless communication to the vehicle monitoring system S2, the charger management system S3, and the driver terminals DP1-DPN and administrator terminal MP deployed at each location, respectively, to perform data transmission and reception. Wireless communication is provided in accordance with wireless communication standards such as wireless Local Area Network (LAN), wireless Wide Area Network (WAN), 4G (fourth-generation mobile communication system), 5G (fifth-generation mobile communication system), or Wi-Fi (registered trademark). 【0023】 The integrated management system S1 is a cloud server or on-premise server that performs charging management for vehicles C1 to CN. Based on the information about each of vehicles C1 to CN transmitted from the vehicle monitoring system S2 and the delivery plan for the next day, the integrated management system S1 determines whether each of vehicles C1 to CN needs to be charged. The integrated management system S1 notifies the driver terminals owned by the drivers of each vehicle of whether the vehicle needs to be charged. The integrated management system S1 also manages whether a vehicle that needs to be charged is connected to chargers CH1 to CHM based on the information about each of vehicles C1 to CN transmitted from the vehicle monitoring system S2 and the information about the power supply status of each of the chargers CH1 to CHM transmitted from the charger management system S3. The integrated management system S1 includes a communication unit 10, a processor 11, and a memory 12. 【0024】 The communication unit 10 is configured using a communication interface circuit for sending and receiving data or information between the vehicle monitoring system S2, the charger management system S3, and the driver terminals DP1-DPN and administrator terminal MP deployed at each location. The communication unit 10 transmits various information (data) output from the processor 11 to the vehicle monitoring system S2, the charger management system S3, the driver terminals DP1-DPN, or the administrator terminal MP. The communication unit 10 also outputs various information (data) transmitted from the vehicle monitoring system S2, the charger management system S3, the driver terminals DP1-DPN, or the administrator terminal MP to the processor 11. 【0025】 The processor 11 is configured using, for example, a Central Processing Unit (hereinafter referred to as "CPU") or a Field Programmable Gate Array (hereinafter referred to as "FPGA"), and works in cooperation with the memory 12 to perform various processing and control. Specifically, the processor 11 refers to the programs and data held in the memory 12 and executes those programs to realize various functions of the integrated management system S1. 【0026】 Memory 12 includes, for example, Random Access Memory (hereinafter referred to as "RAM") as work memory used when executing each process of the processor 11, and Read Only Memory (hereinafter referred to as "ROM") which stores programs and data that define the operation of the processor 11. Memory 12 may also include a storage device that includes either a Solid State Drive (hereinafter referred to as "SSD") or a Hard Disk Drive (hereinafter referred to as "HDD"). Data or information generated or acquired by the processor 11 is temporarily stored in RAM. Programs that define the operation of the processor 11 are written in ROM. 【0027】 The vehicle monitoring system S2 is wirelessly connected to the integrated management system S1 and each vehicle C1-CN, and performs data transmission and reception. The vehicle monitoring system S2 is, for example, a cloud server or on-premise server managed by the company that provides vehicles C1-CN to delivery companies. The vehicle monitoring system S2 collects information about each vehicle C1-CN and transmits it to the integrated management system S1. Note that the vehicle monitoring system S2 is not a required configuration and may be omitted from the configuration of the charging management system 100 if the functions of the vehicle monitoring system S2 are realized by the integrated management system S1. 【0028】 The information regarding vehicle C1 to CN is collected, for example, through the On-Board Diagnostics II (hereinafter referred to as "OBDII") which has a self-diagnostic function of the vehicle's Electronic Control Unit (hereinafter referred to as "ECU"), or through onboard equipment of the vehicle (e.g., Global Positioning System (GPS), etc.), and includes information such as battery charge level, power reception information indicating whether or not power is being received from a charger, or vehicle location information. 【0029】 The charger management system S3 is wirelessly connected to the integrated management system S1 and each charger CH1-CHM to perform data transmission and reception. The charger management system S3 is, for example, a cloud server or on-premise server managed by the provider of the chargers CH1-CHM. The charger management system S3 performs power supply control for each charger CH1-CHM. Note that the charger management system S3 is not a required configuration and may be omitted from the configuration of the charger management system 100 if the functions of the charger management system S3 are realized by the integrated management system S1. 【0030】 Each of the vehicles C1 to CN is a so-called EV vehicle, and is charged by multiple chargers CH1 to CHM installed at base A. After returning to base A, if charging is required, each of the vehicles C1 to CN is connected to a charger of any choice or designated by the driver and is fully charged outside of business hours. Each of the vehicles C1 to CN is connected to a vehicle monitoring system S2 for data communication, and collects information such as the remaining battery charge, charging status (indicating whether or not power is being received from a charger), and vehicle location information, and transmits this information to the vehicle monitoring system S2. The remaining charge may be estimated from information such as voltage, current, or temperature. 【0031】 Each of the chargers CH1 to CHM is connected to the charger management system S3 for data communication and to receive control commands. Each of the chargers CH1 to CHM supplies power to the vehicle connected to the charger based on the control commands transmitted from the charger management system S3. 【0032】 Each of the chargers CH1 to CHM is connected to an external power source. Each of the chargers CH1 to CHM performs power supply control based on power supply information transmitted from the charger management system S3 and charges the vehicle connected to the charging cable. The external power source used is a 3-phase 200V AC power supply. 【0033】 Each of the chargers CH1 to CHM responds with a status based on various control commands transmitted from the charger management system S3. The status here includes the charger's identification information, connection information indicating whether the vehicle is connected or not, charging information indicating before charging starts, during charging, or charging is complete, and the identification information of the connected vehicle, etc. 【0034】 Each of the driver terminals DP1 to DPN is wirelessly connected to the integrated management system S1 to receive data such as information regarding charging requirements. The driver terminals DP1 to DPN are terminals carried by the driver operating the vehicles C1 to CN, and are implemented as, for example, smartphones or tablet devices. The driver terminals DP1 to DPN notify the driver, who is the operator, of information such as the charging requirements of the vehicle being driven by displaying notification screens SC11 and SC12 (see Figure 10) which contain information regarding charging requirements. 【0035】 The administrator terminal MP is wirelessly connected to the integrated management system S1 and receives data such as information regarding the need for charging. The administrator terminal MP is operated by an administrator who manages the vehicles C1-CN and chargers CH1-CHM at base A, and can be implemented using, for example, a smartphone, tablet, personal computer (hereinafter referred to as "PC"), or notebook PC. The administrator terminal MP displays a management screen in real time showing the connection status of chargers CH1-CHM to vehicles C1-CN at base A, or the connection status of vehicles C1-CN to chargers CH1-CHM. The management screen will be described in detail in Embodiment 2. 【0036】 <First operating procedure of the charging management system> Next, with reference to Figure 4, an example of the first operation procedure of the charging management system 100 will be described. Figure 4 is a sequence diagram showing an example of the first operation procedure of the charging management system 100 according to Embodiment 1. The example of the first operation procedure shown in Figure 4 is an operation procedure in which, each time a vehicle returns to base A, a connection response process is performed to determine whether or not each returned vehicle is connected to a charger. 【0037】 Note that while Figure 4 only describes the operation procedure when vehicle C1 returns to base A and connects to charger CH1 as an example, the operation procedures for the other vehicles (vehicles C2 to CN) are similar. Therefore, the operation procedures for the other vehicles are shown as loop process RP1, and their explanation is omitted. Also, Figure 4 omits the illustration of the vehicle monitoring system S2 and the charger management system S3. 【0038】 When vehicle C1 returns to base A (St11), it notifies the vehicle monitoring system S2 of the remaining charge level of its battery (St12). The return of vehicle C1 may be achieved by any method, for example, by location information periodically transmitted from vehicle C1, or by operation of the driver terminal DP1 of the driver operating vehicle C1. 【0039】 The integrated management system S1 performs a charging plan process based on the remaining charge information notified from vehicle C1 and the pre-recorded delivery plan for vehicle C1 for the next day or the amount of charge required for delivery the next day, and determines whether vehicle C1 needs to be charged (St13). Steps St12 and St13 may also be performed by determining whether charging is necessary based on a pre-generated delivery plan without considering the remaining charge status. Based on the determination result of whether charging is necessary, the integrated management system S1 sends a notification regarding whether vehicle C1 needs to be charged to the driver terminal DP1 (St14). The charging plan process in step St13 will be described later. 【0040】 The driver terminal DP1 displays notification screens SC11 and SC12 (see Figure 10) to indicate whether vehicle C1 needs charging (St15). If charging is required, the driver, upon confirming the notification, parks vehicle C1 at a location where a charger CH1 is installed (either arbitrarily or specifically), and then the charging cable is connected (St16). Charger CH1 becomes electrically connected to the arbitrary or specifically determined vehicle C1 that needs charging (St17). 【0041】 After vehicle C1 returns to base A, the integrated management system S1 requests the vehicle monitoring system S2 and the charger management system S3, at any time, to confirm whether vehicle C1 is connected to any or a designated charger for charging (St18). Note that the connection confirmation may be performed multiple times. The integrated management system S1 obtains the connection confirmation results transmitted from the vehicle monitoring system S2 and the charger management system S3 (St19). Note that any method may be used for connection confirmation, and known technologies may be adopted. In addition, a device other than the vehicle monitoring system S2 and the charger management system S3 (e.g., driver terminal DP1) may be used for connection confirmation. For example, the connection confirmation method may be a method in which the driver terminal DP1 reads a 2D code attached to the charger. 【0042】 Based on the connection confirmation result and the correspondence tables TB11A and TB11B (see Figures 8 and 9) between vehicles and chargers generated in the charging plan processing (step St13), the integrated management system S1 performs a connection compatibility determination process to determine whether vehicle C1, which has been determined to require charging, is connected to an arbitrary or designated charger (St20). The integrated management system S1 generates a notification of the result of the connection compatibility determination process, that is, whether vehicle C1 is connected to an arbitrary or designated charger, and sends it to the driver terminal DP1 of the driver (operator) (St21). 【0043】 The driver terminal DP1 receives notification from the integrated management system S1 regarding the result of the connection compatibility determination process, that is, whether or not the vehicle C1 is connected to an arbitrary or designated charger. The driver terminal DP1 displays notification screens SC11 and SC12 (see Figure 10) showing the result of the connection compatibility determination process (St22). 【0044】 The charging management system 100 repeatedly performs the processes described in steps St11 to St22 above each time the vehicle returns to base A until the charging connection deadline (RP1). 【0045】 When the integrated management system S1 determines that the current time at base A has reached the charging connection deadline (for example, "19:00" as shown in Figure 2), it executes a charging plan process based on a pre-recorded correspondence table between vehicles and chargers. The integrated management system S1 then executes a charging plan determination process (St31) to determine whether all vehicles that have been determined to require charging are connected to an arbitrary or designated charger. The process in step St31 will be described later. 【0046】 The integrated management system S1 requests the vehicle monitoring system S2 and the charger management system S3, respectively, to confirm whether a vehicle determined to require charging according to the correspondence table is connected to a charger, either arbitrarily or as specified in the correspondence table (St32). The integrated management system S1 obtains the connection confirmation results transmitted from the vehicle monitoring system S2 and the charger management system S3, respectively (St33). 【0047】 The integrated management system S1 performs a comprehensive connection compatibility determination process (St34) to determine whether all vehicles determined to require charging are connected to an arbitrary or designated charger, based on the connection confirmation results and the vehicle-to-charger correspondence tables TB11A and TB11B (see Figures 8 and 9) generated in the charging plan processing (step St13) performed in response to the return of each vehicle. The process in step St34 will be described later. 【0048】 The integrated management system S1 generates a notification of the result of the connection compatibility assessment process, that is, whether all vehicles are connected to an arbitrary or designated charger. The integrated management system S1 sends this notification to the administrator terminal MP of the administrator (operator) responsible for managing the connection between vehicles and chargers (St35). 【0049】 The administrator terminal MP receives notification from the integrated management system S1 regarding the results of the connection compatibility assessment process, that is, whether all vehicles determined to require charging are connected to an arbitrary or designated charger. The administrator terminal MP displays the charging management screens SC21 and SC31 (see Figures 11 and 12) which show the results of the connection compatibility assessment process (St36). 【0050】 Furthermore, if the administrator terminal MP determines that a vehicle connected to a charger does not require charging, it may display a notification indicating that the connected vehicle or charger is incorrect. Also, if the administrator terminal MP determines that a designated vehicle is not connected to a designated charger, it may display a notification indicating that a vehicle determined to require charging is not connected to any charger. If the administrator terminal MP determines, as a result of the charging plan determination process (step St31), that there are vehicles that have not yet returned to base A, it may display a notification indicating that there are vehicles that have not yet returned. Further details regarding the content of the notifications will be explained in Embodiment 2. 【0051】 Furthermore, the integrated management system S1 may periodically perform the connection compatibility assessment process after the charging connection deadline, until the actual charging begins, and display a charging management screen showing the results on the administrator terminal MP. This allows the integrated management system S1 to notify the administrator in real time of the current connection status between the vehicle and the charger if the administrator corrects the vehicle's connection destination after the charging connection deadline. In addition, the connection compatibility assessment process and the display of the charging management screen after the charging connection deadline may be performed based on administrator operations on the administrator terminal MP. 【0052】 Furthermore, the administrator terminal MP may accept settings for the time of the charging connection deadline, the time for the overall connection response determination process after the charging connection deadline, and the time for displaying the charging management screen, on a day-of-the-week and date-by-day basis. In such cases, the administrator terminal MP transmits the time settings, or information related to time settings, set by the administrator to the integrated management system S1 for recording. 【0053】 <Charging Planning Procedure> Next, with reference to Figure 5, an example of the charging plan processing procedure in step St13 will be described. Figure 5 is a flowchart showing an example of the charging plan processing procedure in the integrated management system S1. 【0054】 The vehicle monitoring system S2 acquires location information and battery information (e.g., charge level information) for each vehicle C1 to CN. The vehicle monitoring system S2 transmits the information for each vehicle C1 to CN to the integrated management system S1. 【0055】 The integrated management system S1 acquires information about vehicle C1 transmitted from the vehicle monitoring system S2. Based on the location information of each vehicle C1 to CN, the integrated management system S1 determines which vehicles have returned to base A. The integrated management system S1 acquires the current charge level information of vehicle C1 that has been determined to have returned to base A (St131). 【0056】 The integrated management system S1 obtains the required battery capacity for the next day's delivery operations based on the next day's delivery plan for vehicle C1 (St132). Note that the next day's delivery plan and required battery capacity information may be pre-generated and stored in memory 12 or similar. 【0057】 The integrated management system S1 determines whether vehicle C1 needs to be charged based on its current charge level and the required battery level for the following day (St133). Specifically, if the integrated management system S1 determines that the current charge level is less than the required battery level for the following day, it determines that vehicle C1 needs to be charged. If the integrated management system S1 determines that the current charge level is not less than the required battery level for the following day, it determines that vehicle C1 does not need to be charged. 【0058】 The integrated management system S1 generates a notification indicating the result of the determination of whether vehicle C1 needs to be charged and sends it to the driver terminal DP1 of vehicle C1's driver (St134). The integrated management system S1 may also specify the charger CH1 to which vehicle C1 is connected by any method (St134). If a charger is specified, the integrated management system S1 sends a notification indicating the number (identification information) of the specified charger CH1 and a notification indicating the result of the determination of whether vehicle C1 needs to be charged, in association with each other, to the driver terminal DP1 (St134). 【0059】 The integrated management system S1 generates a correspondence table TB11B (see Figure 10) which associates vehicle identification information with information on whether each vehicle needs charging and the identification information of the charger designated as the connection destination for each vehicle determined to need charging (St135). Note that the correspondence table TB11A (see Figure 9) generated when no charger is specified simply associates the identification information of each vehicle with the information on whether each vehicle needs charging. 【0060】 The integrated management system S1 executes the processes in steps St131 to St135 each time a vehicle C1 to CN returns, and generates correspondence tables TB11A and TB11B by storing the information corresponding to the returned vehicle C1 to CN in the correspondence tables. 【0061】 <Charging plan determination process procedure and connection compatibility overall determination process procedure> Next, with reference to Figure 6, the charging plan determination process procedure in step St31 (steps St311 to St312) and the connection compatibility overall determination process procedure in step St34 (steps St341 to St343) will be described. Figure 6 is a flowchart showing an example of the charging plan determination process procedure and the connection compatibility overall determination process procedure in the integrated management system S1. 【0062】 The integrated management system S1 determines whether all vehicles C1 to CN managed at base A have returned by the charging connection deadline (St311). 【0063】 If the integrated management system S1 determines in step St311 that the return of all vehicles C1 to CN has not been completed (St311, NO), it generates a notification that there are vehicles that have not returned and sends it to the administrator terminal MP (St312). 【0064】 Meanwhile, if the integrated management system S1 determines in step St311 that the return of all vehicles C1 to CN has been completed (St311, YES), it checks the connection status between chargers CH1 to CHM and vehicles C1 to CN based on the results of the processing in steps St32 to St33 (St341). The connection status here indicates the combination of charger and vehicle that is connected, if a charger to be connected to each vehicle is specified. If a charger to be connected to each vehicle is not specified, the connection status indicates whether or not a charger is connected to each vehicle. 【0065】 In step St311, instead of the integrated management system S1 performing the process of determining whether the return of vehicles C1 to CN has been completed, the administrator may determine whether the return of the vehicles has been completed and notify the integrated management system S1 of the determination result. 【0066】 The integrated management system S1 compares the connection status between chargers CH1~CHM and vehicles C1~CN at the time of the charging connection deadline with the correspondence tables TB11A and TB11B generated in step St13 (St342) to determine whether the connection status between chargers CH1~CHM and vehicles C1~CN matches the correspondence tables TB11A and TB11B (St343). 【0067】 If the integrated management system S1 determines in step St343 that the connection status between chargers CH1~CHM and vehicles C1~CN matches the correspondence table (St343, YES), it terminates the connection correspondence overall determination processing procedure (step St34). 【0068】 On the other hand, if the integrated management system S1 determines in step St343 that the connection status between chargers CH1~CHM and vehicles C1~CN does not match the correspondence tables TB11A and TB11B (St343, NO), it generates a notification that there is a vehicle with an incorrect charger connection (incorrect charging) and sends it to the administrator terminal MP (St35). 【0069】 As described above, the charging management system 100 according to Embodiment 1 can perform vehicle connection management to the charger by the operator (i.e., driver or administrator). Specifically, the charging management system 100 can display a notification on the driver terminal DP1 to visualize information such as whether vehicle C1 needs to be connected to the charger, the time limit for connecting vehicle C1 to the charger, or information about the charger to which vehicle C1 should be connected. Similarly, the charging management system 100 can display a notification (management screen) on the administrator terminal MP to visualize vehicles that are not connected or are connected to the wrong charger. This allows the administrator to more reliably connect all vehicles that have been determined to require charging to the charger before the charging begins. 【0070】 <Second operating procedure for the charging management system> Next, with reference to Figure 7, an example of the second operation procedure of the charging management system 100 will be described. Figure 7 is a sequence diagram showing an example of the second operation procedure of the charging management system 100 according to Embodiment 1. Note that the vehicle monitoring system S2 and the charger management system S3 are not shown in Figure 7. 【0071】 The second operating procedure is the procedure in which, in the first operating procedure shown in Figure 4, the processing in steps St18 to St22, that is, the connection compatibility determination processing performed for each vehicle that returns to base A, is omitted, and the overall connection compatibility determination processing is performed for all vehicles after the charging connection deadline. In addition, the second operating procedure repeats the processing in steps St11 to St17 each time a vehicle returns to base A until the charging connection deadline (RP2). 【0072】 As described above, the charging management system 100 according to Embodiment 1 can perform vehicle connection management to the charger by the operator (i.e., driver or administrator). Specifically, the charging management system 100 can display a notification on the driver terminal DP1 to visualize information such as whether vehicle C1 needs to be connected to the charger, the time limit for connecting vehicle C1 to the charger, or information about the charger to which vehicle C1 should be connected. Similarly, the charging management system 100 can display a notification (management screen) on the administrator terminal MP to visualize vehicles that are not connected or are connected to the wrong charger. This allows the administrator to more reliably connect all vehicles that have been determined to require charging to the charger before the charging begins. 【0073】 Next, the correspondence tables TB11A and TB11B generated in step St135, and the correspondence tables TB12A and TB12B referenced in step St342 will be described with reference to Figures 8 and 9, respectively. Figure 8 is a diagram showing an example of correspondence tables TB11A and TB11B. Figure 9 is a diagram showing an example of correspondence tables TB12A and TB12B. Note that the correspondence tables TB11A, TB11B, TB12A, and TB12B shown in Figures 8 and 9 are examples and are not limited thereto. 【0074】 In addition, the vehicle identification information shown in Figures 8 and 9 corresponds to the following: Identification information "EV#01" corresponds to vehicle C1, identification information "EV#02" corresponds to vehicle C2, identification information "EV#03" corresponds to vehicle C3, and identification information "EV#04" corresponds to vehicle C4. 【0075】 The correspondence tables TB11A and TB12A shown in Figure 8 are examples of correspondence tables generated when a vehicle requiring charging connects to any charger. Correspondence table TB11A stores the identification information of the vehicle that has returned to base A and the charging information indicating whether or not charging is required for each vehicle. Correspondence table TB11A is updated by the integrated management system S1 each time a vehicle returns to base A. 【0076】 For example, the correspondence table TB11A shown in Figure 8 stores the identification information "EV#01", "EV#02", "EV#03", and "EV#04" for the four vehicles C1 to C4 that have returned to base A. It associates the identification information of these vehicles C1, C3 to C4 with the charging information "Required" indicating that vehicles C1, C3 to C4 need charging, and associates the identification information of vehicle C2 with the charging information "Not Required" indicating that vehicle C2 does not need charging. 【0077】 The correspondence table TB12A stores, for each vehicle, the vehicle identification information, the charging necessity information stored in the correspondence table TB11A, the charging necessity information (plan) indicating whether the charging necessity was determined in advance by the integrated management system S1, the charging necessity information (actual) indicating whether the vehicle and any charger are connected at the charging connection deadline, and the mismatch information indicating whether the charging necessity information (plan) and the charging necessity information (actual) do not match. 【0078】 When the integrated management system S1 determines that the time for the charging connection deadline has arrived, it executes a charging plan determination process and a connection compatibility determination overall process. It then generates a correspondence table TB12A by further associating the information about each vehicle stored in the correspondence table TB11A with charging information (actual) indicating whether the vehicle is receiving power as a result of the connection compatibility determination overall process, and number information (actual) indicating the identification information of the charger connected to the vehicle. 【0079】 For example, in the correspondence table TB12A shown in Figure 8, the charging information (actual) "connected" is associated with the identification information of vehicles C1 and C3, and the charging information (actual) "not connected" is associated with the identification information of vehicles C2 and C4. In addition, as mismatch information indicating whether or not there is a discrepancy between the charging information (planned) and the charging information (actual), a check is placed in the identification information of vehicle C4 to indicate that there is a discrepancy between the charging information (planned) and the charging information (actual). If the integrated management system S1 determines that there is a discrepancy between the vehicles, it generates a notification that there is a discrepancy between the charging information (planned) and the charging information (actual) and sends it to the administrator terminal MP. 【0080】 In the example shown in Figure 8, the integrated management system S1 detects a discrepancy when vehicle C4, which requires charging, is not connected to a charger. However, it similarly detects a discrepancy when a vehicle that does not require charging is connected to a charger. This allows the integrated management system S1 to manage connections between vehicles and chargers so that even if the number of chargers becomes insufficient due to the connection of vehicles that do not require charging, all vehicles determined to require charging are connected to chargers. 【0081】 The correspondence tables TB11B and TB12B shown in Figure 9 are examples of correspondence tables generated when a vehicle requiring charging is connected to a designated charger. Correspondence table TB11B stores the identification information of the vehicle that has returned to base A, the charging information indicating whether charging is required, and the identification number of the charger used to charge the vehicle, in association with each other. Correspondence table TB11B is generated (updated) by the integrated management system S1 each time a vehicle returns to base A. 【0082】 For example, the correspondence table TB11B shown in Figure 9 stores the identification information "EV#01", "EV#02", "EV#03", and "EV#04" of the four vehicles that returned to base A. Correspondence table TB11B associates the identification information of vehicle C1 with the charging information "Required" and the charger identification number "No.1", the identification information of vehicle C2 with the charging information "Not Required" and the charger identification number "-(None)", the identification information of vehicle C3 with the charging information "Required" and the charger identification number "No.6", and the identification information of vehicle C4 with the charging information "Required" and the charger identification number "No.7". 【0083】 Furthermore, correspondence table TB12B is generated by the integrated management system S1, and is created by further associating the results of the connection compatibility determination process with correspondence table TB11B for the charging connection deadline. 【0084】 The integrated management system S1 generates a correspondence table TB12B that associates vehicle identification information with charging necessity information stored in the correspondence table TB11B, specifically: charging information (plan) indicating charging necessity determined in advance by the integrated management system S1; charging information (actual) indicating whether the vehicle is connected to a designated charger at the time of the charging connection deadline; the identification number (plan) of the designated charger; the identification number (actual) of the charger to which the vehicle is actually connected; and mismatch information indicating whether there is a mismatch between the charging information (plan) and the charging information (actual), or between the identification number (plan) and the identification number (actual). The integrated management system S1 also notifies the administrator terminal MP of this mismatch if it determines that there is a mismatch between the charging information (plan) and the charging information (actual), or between the identification number (plan) and the identification number (actual). 【0085】 For example, in the correspondence table TB12B shown in Figure 9, at the charging connection deadline, the identification information of vehicle C1 is associated with the charging information (actual) of vehicle C1, "connected," and the charging device identification number (actual) "No. 1." The identification information of vehicle C2 is associated with the charging information (actual) of vehicle C2, "not connected," and the charging device identification number (actual) "-(none)." The identification information of vehicle C3 is associated with the charging information (actual) of vehicle C3, "connected," and the charging device identification number (actual) "No. 5." The identification information of vehicle C4 is associated with the charging information (actual) of vehicle C4, "connected," and the charging device identification number (actual) "No. 7." Furthermore, the correspondence table TB12B associates mismatch information, indicating whether there is a discrepancy between the planned charging information and the actual charging information, or between the planned identification number and the actual identification number, with the identification information of vehicle C3. This check notifies the system of a discrepancy between the planned identification information "No. 6" of the charger to which vehicle C3 should be connected and the actual identification number "No. 5" of the charger to which it is actually connected. If the integrated management system S1 determines that there is a discrepancy between the planned charging information and the actual charging information, it generates a notification indicating that there is a discrepancy between the planned charging information and the actual charging information and sends it to the administrator terminal MP. 【0086】 Furthermore, vehicle identification information is not limited to identification information assigned to each vehicle (for example, "EV#01"), but may also include the vehicle's license plate, or a driver ID or driver's name used to identify the driver operating the vehicle. 【0087】 Next, with reference to Figure 10, the notification screens SC11 and SC12 that inform the driver whether charging is necessary will be described. Figure 10 shows examples of notification screens SC11 and SC12 displayed on driver terminals DP1 to DPN. Note that the notification screens SC11 and SC12 shown in Figure 10 are just examples and are not limited to them. 【0088】 If the integrated management system S1 determines that a vehicle returning to base A requires charging, it generates notification screens SC11 and SC12 requesting the vehicle to be charged, i.e., connected to an arbitrary or designated charger, and sends them to the driver's terminals DP1 to DPN. 【0089】 The notification screen SC11 is generated when only charging needs to be notified and is displayed on the driver terminals DP1~DPN. The notification screen SC11 includes the message Msg11 "Charging is required" which notifies that charging is needed, the message Msg12 "Please connect to the charger by 17:00" which notifies the deadline for connecting to the charger, and the confirmation button BT11. 【0090】 When the confirmation button BT11 is pressed (selected) by the driver, the driver terminals DP1 to DPN will terminate the display of the notification screen SC11. Alternatively, when the confirmation button BT11 is pressed (selected) by the driver, the driver terminals DP1 to DPN may send a notification to the integrated management system S1 indicating that they have confirmed (acknowledged) the notification content shown on the notification screen SC11, namely whether charging is required and the charging connection deadline. 【0091】 The notification screen SC12 is generated when it is necessary to notify the driver whether charging is required and which charger to connect the vehicle to, and is displayed on the driver terminals DP1~DPN. The notification screen SC12 includes a message Msg13 "Charger number: Please charge at No. 6" which notifies the driver that charging is required and which charger will be used to charge this vehicle, and a confirmation button BT12. The notification screen SC12 may also be generated to include a message Msg12 that notifies the charging connection deadline, etc. 【0092】 When the driver presses (selects) the confirmation button BT12, the driver terminals DP1 to DPN will terminate the display of the notification screen SC12. Alternatively, when the driver presses (selects) the confirmation button BT12, the driver terminals DP1 to DPN may send a notification to the integrated management system S1 indicating that the driver has confirmed (acknowledged) the notification content shown on the notification screen SC11, namely whether charging is required and the charger to which the vehicle will be connected. 【0093】 Furthermore, while the notification screens SC11 and SC12 shown in Figure 10 illustrate an example of notifying the vehicle that it needs charging, they may also include a message indicating that charging is not necessary. In such cases, the notification screens SC11 and SC12 may omit messages such as Msg12, which notifies the charging connection deadline, or Msg13, which notifies the charger on which the vehicle will be charged. 【0094】 As described above, the integrated management system S1 in Embodiment 1 can perform the task of connecting the vehicle to an arbitrary or designated charger by the driver by notifying the driver of whether or not the vehicle needs charging, or information such as the charger to which the vehicle should be connected, upon the driver's return to base A. Furthermore, the integrated management system S1 can facilitate the connection of the vehicle to the charger by notifying the driver of the deadline for connecting the vehicle to the charger. This allows the integrated management system S1 to more reliably complete the connection between the vehicle requiring charging and the charger before the actual charging begins. 【0095】 Next, referring to FIGS. 11 and 12 respectively, a display example of the charging management screens SC21 and SC31 displayed when the vehicle and the charger are incorrectly connected at the time of the charging connection deadline will be described. FIG. 11 is a diagram showing an alert display example on the charging management screen SC21. FIG. 12 is a diagram showing an alert display example on the charging management screen SC31. Note that the alert display examples shown in FIGS. 11 and 12 are merely examples and are not limited thereto. 【0096】 The charging management screen SC21 shown in FIG. 11 includes an alert AL21 that notifies of an incorrect connection to a charger different from the charger specified in the correspondence table TB11B. The alert AL21 includes a face image PIC21 of the driver of the vehicle determined to be incorrectly connected and information IF21 regarding the incorrect connection. 【0097】 The information IF21 regarding the incorrect connection includes information about the driver of the vehicle determined to be incorrectly connected, information about the vehicle determined to be incorrectly connected, information about the current connection destination of the vehicle, or information about the correct connection destination of the vehicle, etc. For example, the alert AL21 shown in FIG. 11 includes the name information "〇da〇o" of the driver of the vehicle determined to be incorrectly connected, the license plate information "YY yyy a XX-04" of the vehicle determined to be incorrectly connected, and a message "Incorrectly connected to No. 3. Please reconnect to No. 5" indicating information about the current connection destination of the vehicle and information about the correct connection destination of the vehicle. 【0098】 The charging management screen SC31 shown in FIG. 12 includes an alert AL31 that notifies of a non-connection to a charger different from the charger specified in the correspondence table TB11B. The alert AL31 includes a face image PIC31 of the driver of the vehicle determined to be non-connected, a charging connection deadline notification IF31 that notifies that the current time is the charging connection deadline, and information IF32 regarding the non-connection. 【0099】 The information IF32 regarding incorrect connection includes information about the driver of the vehicle determined to be unconnected, information about the vehicle determined to be unconnected, or information about the correct connection destination of the vehicle, etc. For example, the alert AL31 shown in FIG. 12 includes the name information "〇T〇o" of the driver of the vehicle determined to be unconnected, the license plate information "YY yyy a XX-04" of the vehicle determined to be unconnected, and the message "Not connected to No. 13" indicating information about the correct connection destination of the vehicle. 【0100】 Note that the alerts AL21 and AL31 may be alerts that notify an incorrect connection where a vehicle that does not require charging is connected to an arbitrary charger, or may be alerts that notify that the connection destination is not connected to any charger by any vehicle. 【0101】 Also, the charging management screens SC21 and SC31 shown in FIGS. 11 and 12 may display the display areas AR25A and AR35A described in FIGS. 15 and 16 instead of, or together with, the alerts AL21 and AL31. 【0102】 As described above, the integrated management system S1 in Embodiment 1 can notify the administrator, based on the alerts AL21 and AL31, of a notification that the connection state between the vehicle and the charger is an incorrect connection, information about the driver of the vehicle determined to be in an incorrect connection, information about the vehicle determined to be in an incorrect connection, information about the current connection destination of the vehicle, or information about the correct connection destination of the vehicle, etc. Thereby, the integrated management system S1 can more efficiently manage the connection states of the vehicles C1 to CN and the chargers CH1 to CHM by the administrator. 【0103】 (Process to Embodiment 2) The charging management system 100 according to Embodiment 1 demonstrates an example of managing all vehicles that require charging before the start of charging by visualizing charging management screens SC21 and SC31 that show the administrator a list of the connection status between vehicles and chargers at the charging connection deadline, thereby ensuring that all vehicles requiring charging are connected to an arbitrary or designated charger. However, there is a possibility that vehicles may return to the base at different times, drivers may forget to connect their vehicles to the chargers, or they may connect to a charger other than the designated one. Therefore, the charging management system 100 according to Embodiment 2 describes an example of an information display method that visualizes the state transitions of vehicles C1 to CN or chargers CH1 to CHM to the administrator by displaying a charging management screen in real time that shows the current status of vehicles C1 to CN and chargers CH1 to CHM, allowing the administrator to grasp in real time whether vehicles are incorrectly connected or not at base A. In the following description, the same reference numerals are used for components that are the same as in Embodiment 1, and their explanations are omitted. 【0104】 (Embodiment 2) <Example of a charging management screen at any given time> The charging management screens SC21 and SC31 displayed on the administrator terminal MP will be explained with reference to Figures 13 and 14, respectively. Figure 13 is a diagram showing an example of the charging management screen SC21 for vehicles C1 to CN with respect to chargers CH1 to CHM. Figure 14 is a diagram showing an example of the charging management screen SC31 for vehicles C1 to CN with respect to chargers CH1 to CHM. Note that the charging management screens SC21 and SC31 shown in Figures 13 and 14 are examples and are not limited thereto. Also, in the charging management screens SC21 and SC31 shown in Figures 13 and 14, only representative icons are labeled with symbols for clarity. 【0105】 The integrated management system S1 acquires power reception information for each vehicle C1 to CN from the vehicle monitoring system S2, and acquires connection information for each charger CH1 to CHM from the charger management system S3 periodically or at predetermined times such as the charging connection deadline. Based on the acquired power reception information and connection information, the integrated management system S1 generates a charging management screen SC21 that visualizes the vehicles C1 to CN connected to each charger CH1 to CHM, or a charging management screen SC31 that visualizes the chargers CH1 to CHM connected to each vehicle C1 to CN. The integrated management system S1 transmits the generated charging management screens SC21 and SC31 to the administrator terminal MP for display. 【0106】 The charging management screen SC21 includes a general icon IC20, a charger icon IC21, a vehicle information icon IC22, and vehicle icons IC23 that indicate the vehicles C1-CN connected to each charger indicated by the charger icon IC21. The charging management screen SC21 is displayed on the administrator terminal MP and visualizes the connection status of vehicles C1-CN to each charger CH1-CHM installed at base A for the administrator. 【0107】 The comprehensive icon IC20 indicates, using numbers and bar graph lengths, the number of vehicles currently in transit, the number of vehicles returning to base A, the number of vehicles returning to base A that require charging, or the number of vehicles returning to base A that do not require charging, among all vehicles C1 to CN belonging to base A. Note that the method of displaying the number of vehicles is not limited to this and other display methods are also permitted. 【0108】 For example, the combined icon IC20 shown in Figure 13 indicates that of the 40 vehicles belonging to base A, 34 are currently making deliveries and 4 have returned to base A. Furthermore, the combined icon IC20 indicates that of the 4 vehicles returned to base A, 3 require charging and 1 does not. 【0109】 The SC21 charging management screen has a display area for each charger where various icons indicating the status of the charger are displayed, arranged in a grid. For example, the SC21 charging management screen shown in Figure 13 has 15 display areas that indicate the status of chargers corresponding to identification numbers "01" to "05", "11" to "15", and "20" to "25". Specifically, in the AR21 display area of ​​the SC21 charging management screen, various icons indicating the status of the charger corresponding to identification number "01" are displayed. 【0110】 The charger icon IC21 corresponds to each charger CH1 to CHM installed at site A, and is displayed with an identification number as information about the charger that makes it possible to identify each charger CH1 to CHM. For example, the charger icon IC21 shown in Figure 13 indicates that it is charger CH11, to which the identification number "11" has been assigned. 【0111】 The vehicle information icon IC22 displays information about the vehicle connected to chargers CH1 to CHM indicated by each charger icon IC21. For example, the vehicle information icon IC22 shown in Figure 13 includes license plate information "YY yyy a XX-02" as vehicle information. The vehicle information included in the vehicle information icon IC22 only needs to be information that can identify a vehicle belonging to base A, and may include, for example, vehicle identification information or information about the driver. 【0112】 The vehicle icon IC23 visualizes whether or not a vehicle is connected to the charger indicated by the charger icon IC21. For example, the vehicle icon IC23 shown in Figure 13 indicates that the vehicle indicated by the vehicle information icon IC22 is connected to the charger indicated by the charger icon IC21. 【0113】 The charging management screen SC31 includes a general icon IC30, a vehicle information icon IC31, vehicle status icons IC32 and IC34, a charging requirement icon IC33, and a charger information icon IC35. The charging management screen SC31 is displayed on the administrator terminal MP and visualizes the connection status of chargers CH1 to CHM for each vehicle C1 to CN belonging to base A to the administrator. 【0114】 The comprehensive icon IC30 is similar to the comprehensive icon IC20 shown in Figure 14, and indicates, using numbers and the length of a bar graph, the number of vehicles currently in transit, the number of vehicles returning to base A, the number of vehicles returning to base A that require charging, or the number of vehicles returning to base A that do not require charging, among all vehicles C1 to CN belonging to base A. 【0115】 The charging management screen SC31 has a display area for each vehicle where various icons indicating the vehicle's status are displayed, arranged in a grid. For example, the charging management screen SC31 shown in Figure 14 has 15 display areas that indicate the status of each vehicle corresponding to the license plate information "YY yyy a XX-01" to "YY yyy a XX-15". The charging management screen SC31 displays various icons indicating the status of the vehicle corresponding to the license plate information "YY yyy a XX-01" in display area AR31. 【0116】 The vehicle information icon IC31 corresponds to each vehicle C1 to CN belonging to base A, and is displayed with vehicle information attached to identify each vehicle C1 to CN. For example, the vehicle information icon IC31 shown in Figure 14 indicates that the vehicle has the license plate information "YY yyy a XX-06". The vehicle information included in the vehicle information icon IC31 only needs to be information that can identify a vehicle belonging to base A, and may include, for example, vehicle identification information or information about the driver. 【0117】 The vehicle status icon IC32 indicates that the vehicle corresponding to the icon IC32 has returned to base A. The vehicle status icon IC32 is only displayed when each vehicle C1 to CN belonging to base A has returned to base A. 【0118】 On the other hand, the vehicle status icon IC34 indicates that the vehicle corresponding to the vehicle status icon IC34 is currently in transit. The vehicle status icon IC34 is displayed only when each vehicle C1 to CN belonging to base A has not returned to base A and is currently in transit. 【0119】 The charging requirement icon IC33 indicates whether each vehicle C1 to CN belonging to base A requires charging. The charging requirement icon IC33 displays the result of the determination of whether charging is required for the vehicle corresponding to the charging requirement icon IC33. For example, the charging requirement icon IC33 shown in Figure 14 indicates that charging is not required for the vehicle corresponding to the vehicle information icon IC31. Although not shown in the figures in this disclosure, if charging is required for the vehicle corresponding to the vehicle information icon IC31, text such as "Charging Required" may be displayed. 【0120】 The charger information icon IC35 displays information about the chargers connected to each vehicle C1-CN. For example, the charger information icon IC35 shown in Figure 14 displays a charger icon (illustration) indicating that a charger is connected to the vehicle corresponding to the vehicle information icon, and the identification number "#02" as information about the charger connected to this vehicle. 【0121】 As described above, the integrated management system S1 in Embodiment 2 can visualize all vehicles C1 to CN connected to each charger CH1 to CHM installed at base A via the charging management screen SC21. Furthermore, the integrated management system S1 can visualize all chargers CH1 to CHM connected to each vehicle C1 to CN belonging to base A via the charging management screen SC31. This allows the integrated management system S1 to more efficiently manage the connection between vehicles C1 to CN and chargers CH1 to CHM at base A, which is performed by the administrator. 【0122】 Furthermore, the integrated management system S1 may display the charging management screen SC21 and the charging management screen SC31 in a switchable manner. This allows the administrator to switch between checking the connection status of vehicles C1-CN to chargers CH1-CHM and the connection status of chargers CH1-CHM to vehicles C1-CN, so that the administrator can choose the display method that is more suitable to their preference or management purpose. For example, the administrator can check the connection status of each charger CH1-CHM using the charging management screen SC21, or check the connection status of each vehicle C1-CN, as well as whether each vehicle C1-CN has returned, or whether each vehicle C1-CN requires charging, etc., using the charging management screen SC31. 【0123】 <Examples of display transitions for various icons> Next, with reference to Figure 15, an example of the display transition of various icons on the charging management screens SC21 and SC31 will be explained. Figure 15 is a diagram showing an example of the display transition of various icons. Note that the various icons shown in Figure 15 are just examples and are not limited to these. 【0124】 The example of the display transition of various icons shown in Figure 15 illustrates the display transition of various icons on the charging management screens SC21 and SC31 displayed on the administrator terminal MP during the first operation procedure, that is, while the processes of steps St11 to St22 shown in Figure 4 are repeatedly executed. 【0125】 The integrated management system S1 determines, based on the vehicle's location information, whether or not the vehicle needs to be charged if it determines that the vehicle corresponding to the license plate information "YY yyy a XX-01" has returned to base A (St40). 【0126】 If the integrated management system S1 determines that charging is necessary for the vehicle (St41), it generates a charging management screen SC21 including display area AR21A, or a charging management screen SC31 including display area AR31A, and displays it on the administrator terminal MP. 【0127】 Here, display area AR21A includes a charger information icon IC21A which contains the charger identification number "01" and an icon (illustration) representing the charger. Display area AR31A also includes a vehicle information icon IC31A which contains the vehicle's license plate information "YY yyy a XX-01" and an icon (illustration) representing the vehicle, and a vehicle status icon IC32A which indicates the vehicle's status "returned". 【0128】 The integrated management system S1 sends a notification to the driver terminal owned by the vehicle's driver requesting vehicle charging. If the vehicle is directed to an arbitrary or designated charger "#01" (St42), it generates a charging management screen SC21 including display area AR22A, or a charging management screen SC31 including display area AR32A, and displays it on the administrator terminal MP. 【0129】 Here, display area AR22A includes, in addition to the charger information icon IC21A displayed in display area AR21A, a vehicle information icon IC22A that shows information about the vehicle guided to the charger (in this case, license plate information "YY yyy あ XX-01"). Note that if the charger connected to the vehicle is optional, the display of the vehicle information icon IC22A in display area AR22A may be omitted. 【0130】 Furthermore, display area AR32A includes the vehicle information icon IC31A and vehicle status icon IC32A displayed in display area AR31A, as well as the charger information icon IC33A which shows information about the charger designated as the connection destination (in this case, identification number "#01"). Note that if the charger connected to the vehicle is arbitrary, display area AR32A may display a vehicle status icon such as "Charging Required," or the display of the charger information icon IC33A may be omitted. 【0131】 The integrated management system S1 performs a charging check, and if it determines (confirms) that the vehicle is connected to the designated charger "#01" based on the power reception information transmitted from the vehicle monitoring system S2 as the charging check result, the connection information transmitted from the charger management system S3, and the correspondence tables TB11A and TB11B (St43), it generates a charging management screen SC21 including display area AR23A, or a charging management screen SC31 including display area AR33A, and displays it on the administrator terminal MP. 【0132】 Here, display area AR23A includes the charger information icon IC21A and vehicle information icon IC22A displayed in display area AR22A, as well as the vehicle icon IC23A indicating that a vehicle corresponding to the vehicle information icon IC22A has been connected. 【0133】 Furthermore, in display area AR33A, among the vehicle status icon IC32A and charger information icon IC33A displayed in display area AR32A, the vehicle status icon IC32A, which indicates that the vehicle has returned, is changed to the vehicle status icon IC34A, which indicates that the vehicle is connected to the charger corresponding to the charger information icon IC33A. 【0134】 On the other hand, if the integrated management system S1 determines that charging is not necessary for the vehicle (St44), it generates a charging management screen SC21 including display area AR21A, or a charging management screen SC31 including display area AR34A, and displays it on the administrator terminal MP. 【0135】 Here, display area AR34A includes the vehicle information icon IC31A and the vehicle status icon IC32A displayed in display area AR31A, as well as the charging requirement icon IC35A which indicates that the vehicle indicated by the vehicle information icon IC31A does not require charging. 【0136】 Furthermore, the integrated management system S1 performs a charging check, and if it determines (confirms) that the vehicle is connected to the wrong charger "#02" based on the power reception information transmitted from the vehicle monitoring system S2 as the charging check result, the connection information transmitted from the charger management system S3, and the correspondence tables TB11A and TB11B (St45), it generates a charging management screen SC21 including display area AR25A, or a charging management screen SC31 including display area AR35A, and displays it on the administrator terminal MP. 【0137】 Here, display area AR25A shows the status of the charger corresponding to the identification information "#02". In step St45, display area AR25A is highlighted in a different color (e.g., red) from the colors of other display areas (e.g., white, black, etc.) and includes a vehicle information icon IC24A that shows information about the incorrectly connected vehicle (in this case, the vehicle's license plate information "YY yyy あ XX-01"). 【0138】 In display area AR35A, among the vehicle information icon IC31A, vehicle status icon IC32A, and charger information icon IC33A displayed in display area AR32A, the vehicle status icon IC32A is changed to vehicle status icon IC36A, which indicates an incorrect charger connection, and the identification number "#01" indicating a specified charger in the charger information icon IC33A is changed to charger icon IC37A, which has information "#01→#02" indicating that it is connected to the incorrect identification number "#02" instead of the correct identification number "#01". In addition, display area AR35A is highlighted in a different color (e.g., red) from the color of other display areas (e.g., black). 【0139】 <Examples of display transitions for various icons> Next, with reference to Figure 16, we will explain Example 2 of the display transitions for various icons on the charging management screens SC21 and SC31. Figure 16 is a diagram showing Example 2 of the display transitions for various icons. Note that the various icons shown in Figure 16 are just examples and are not limited to these. 【0140】 The second example of icon display transitions shown in Figure 16 describes the display transitions of various icons on the charging management screens SC21 and SC31 displayed on the administrator terminal MP during the second operation procedure, that is, while the series of processes shown in Figure 7, steps St11 to St15 and steps St31 to St36, are repeatedly executed. Note that the display transitions of various icons on the charging management screens SC21 and SC31 displayed on the administrator terminal MP during the processing of steps St31 to St36 of the first operation procedure may be the same as the display transitions of various icons on the charging management screens SC21 and SC31 displayed after the charging connection deadline in the second example of icon display transitions. 【0141】 Here, the processing of steps St40 to St42 and step St44 shown in Figure 16 is the same as the processing of steps St40 to St42 and step St44 shown in Figure 15, so the explanation is omitted. In addition, the display transition example 2 of the various icons in the display areas AR21A to AR22A, AR24A, AR31A to AR32A, AR34A displayed on the charging management screen SC21, SC31 shown in steps St40 to St42 and step St44 shown in Figure 16 is the same as the display transition example 1 of the various icons shown in Figure 15, so the explanation is omitted. 【0142】 The integrated management system S1 performs a charging check at the charging connection deadline. Based on the power reception information transmitted from the vehicle monitoring system S2 as the charging check result, the connection information transmitted from the charger management system S3, and the correspondence tables TB11A and TB11B, if it determines (confirms) that the vehicle has been connected to the designated charger "#01" (St43), it generates a charging management screen SC21 including display area AR23A, or a charging management screen SC31 including display area AR33A, and displays it on the administrator terminal MP. 【0143】 Furthermore, the integrated management system S1 performs a charging check, and if it determines (confirms) that the vehicle is connected to the wrong charger "#01" based on the power reception information transmitted from the vehicle monitoring system S2 as the charging check result, the connection information transmitted from the charger management system S3, and the correspondence tables TB11A and TB11B (St45), it generates a charging management screen SC21 including display area AR25A, or a charging management screen SC31 including display area AR35A, and displays it on the administrator terminal MP. 【0144】 As described above, the integrated management system S1 in Embodiment 2 can notify the administrator of the vehicle connection status to each charger CH1-CHM, information about the vehicles connected to each charger CH1-CHM, or whether the vehicles connected to each charger CH1-CHM are correct, based on the display transition of icons on the charging management screen SC21. This allows the integrated management system S1 to make the management of the status of each charger CH1-CHM more efficient for the administrator. 【0145】 Furthermore, as described above, the integrated management system S1 in Embodiment 2 can notify the administrator of the connection status of the charger to each vehicle C1 to CN, information about the charger connected to each vehicle C1 to CN, or whether the vehicle connected to each vehicle C1 to CN is correct, based on the display transition of icons on the charging management screen SC31. This allows the integrated management system S1 to make the management of the status of each vehicle C1 to CN more efficient for the administrator. 【0146】 (Background leading to Embodiment 3) The charging management system 100 according to Embodiment 2 demonstrates an example of managing all vehicles that require charging before the start of charging by notifying the administrator of the connection status between vehicles C1 to CN and chargers CH1 to CHM, thereby ensuring that all vehicles requiring charging are connected to any or a designated charger. 【0147】 Here, for vehicles C1 to CN that have been determined to require charging, it is necessary to perform an identification process (pairing process) to determine which vehicle C1 to CN is connected to which charger CH1 to CHM, and to correct any misconnections based on the identification process results, before the charging connection deadline. Therefore, the charging management system 100 according to Embodiment 3 describes an example of a charging system control method that performs the identification process for vehicles connected to each charger. In the following description, the same reference numerals are used for components that are the same as in Embodiments 1 and 2, and their descriptions are omitted. 【0148】 (Embodiment 3) Referring to Figure 17, the timing of the identification process for the connection combinations of vehicles C1-CN and chargers CH1-CHM will be explained. Figure 17 is a diagram illustrating the timing of the identification process between vehicles C1-CN and chargers CH1-CHM in Embodiment 3. Note that the identification process timing shown in Figure 17 is an example and is not limited thereto. 【0149】 The charging management system 100 performs an identification process to determine which vehicles C1-CN are connected to which chargers CH1-CHM for vehicles C1-CN that have been determined to require charging, during a pre-charging time (e.g., "17:00-18:00") prior to the charging connection deadline (e.g., "19:00"). Pre-charging is a charging process performed in advance to identify (pair) the connection status between the vehicle and the charger. 【0150】 The charging management system 100 notifies the administrator of the connection pair information of the vehicle and charger identified during the pre-charging time. If the notified vehicle and charger connection pair differs from the combination specified in the correspondence table, the administrator reconnects the vehicle to the correct charger specified in the correspondence table by the charging connection deadline. This ensures that the administrator can connect the vehicle and charger in the combination specified in the correspondence table by the time the main charging begins. Therefore, the charging management system 100 can perform vehicle charging management to ensure that the main charging is carried out reliably for vehicles that require charging. 【0151】 Next, with reference to Figure 18, an example of the identification process for connection combinations between vehicles C1-CN and chargers CH1-CHM will be explained. Figure 18 is a diagram showing an example of vehicle identification in a connected state. Note that the identification process example shown in Figure 18 is just one example and is not limited thereto. 【0152】 The integrated management system S1 requests the charger management system S3 to perform a power supply process to supply power to one or more chargers. The integrated management system S1 requests the vehicle monitoring system S2 to transmit power receiving information indicating the power receiving status of each vehicle C1 to CN. For example, in the example shown in Figure 18, the integrated management system S1 requests the charger management system S3 to perform a power supply process based on a pre-planned power supply plan PLN. Note that the power supply plan PLN shown in Figure 18 is provided to make the power supply process performed by the charger management system S3 easier to understand and may be omitted. 【0153】 The charger management system S3, based on the power supply requests from the integrated management system S1, causes different chargers to supply power at different time periods. As shown in Figure 18, the charger management system S3 supplies power to charger "Ch#01" from "17:00-17:02", to charger "Ch#02" from "17:02-17:04", to charger "Ch#03" from "17:04-17:06", and to charger "Ch#04" from "17:06-17:08". 【0154】 The vehicle monitoring system S2 periodically collects power reception information from the ECUs of each vehicle C1 to CN and transmits it to the integrated management system S1. 【0155】 The integrated management system S1 identifies the vehicles connected to each charger based on the charger that received power during the power supply process and the vehicles C1 to CN that received power, as indicated by the power reception information. For example, in the example shown in Figure 18, the integrated management system S1 determines, based on the power reception information, that vehicle "EV#03" was receiving power at time "17:01", vehicle "EV#02" was receiving power at time "17:03", vehicle "EV#04" was receiving power at time "17:05", and vehicle "EV#01" was receiving power at time "17:07". As a result, the integrated management system S1 can identify that vehicle "EV#03" is connected to charger "Ch#01", vehicle "EV#02" is connected to charger "Ch#02", vehicle "EV#04" is connected to charger "Ch#03", and vehicle "EV#01" is connected to charger "Ch#04". 【0156】 <Example of connection identification procedure between vehicle and charger> Next, with reference to Figure 19, an example of the connection identification procedure between vehicles C1-CN and chargers CH1-CHM will be described. Figure 19 is a sequence diagram showing an example of the identification procedure of the charging management system 100 according to Embodiment 3. Note that the connection identification procedure example shown in Figure 19 shows an example in which power is supplied to chargers CH2 and CH3 in a time-division manner. 【0157】 The integrated management system S1 instructs the charger management system S3 to start supplying power to charger CH2 (St51A). 【0158】 The charger management system S3 instructs charger CH2 to start supplying power based on instructions sent from the integrated management system S1 (St52A). Charger CH2 supplies power to the vehicle connected to its charger based on instructions sent from the charger management system S3 (St53A). The vehicle connected to charger CH2 is charged by charger CH2 (St54A). At this point, the vehicle's ECU detects that the vehicle is receiving power using a sensor that detects the battery charge status. 【0159】 The integrated management system S1 instructs the vehicle monitoring system S2 to check the power supply status of each vehicle C1 to CN (St55). 【0160】 The vehicle monitoring system S2 instructs each of the vehicles C1 to CN to check their current power supply status (St56). Each of the vehicles C1 to CN generates power supply information indicating its current power supply status, associates the power supply information with identification information that can identify its own vehicle, and transmits it to the vehicle monitoring system S2 (St57). The vehicle monitoring system S2 transmits (notifies) the power supply information transmitted from each of the vehicles C1 to CN to the integrated management system S1 (St58). 【0161】 The integrated management system S1 associates information from charger CH2, which supplied power, with identification information of each of the vehicles C1 to CN in which a power-receiving state was detected, and identifies the vehicle connected to charger CH2 (St59). 【0162】 The charging management system 100 repeatedly executes a set of processes: a power supply process to supply power to at least one charger as shown in steps St51A to St54A, and a process to check the vehicle's power receiving status and identify the connection pair between the vehicle and charger CH2 as shown in steps St55 to St59. By repeatedly executing these processes, the charging management system 100 identifies the vehicles connected to each charger CH1 to CHM. 【0163】 For example, in the example shown in Figure 19, the charging management system 100 performs a power supply process to supply power to the charger CH3 in steps St51B to St54B, and a process to check the vehicle's power receiving status and identify the connection pair between the vehicle and the charger CH3 in steps St55 to St59. 【0164】 As described above, the charging management system 100 according to Embodiment 3 can supply power to one or more chargers in a time-division manner and identify vehicles connected to each charger CH1 to CHM based on the power reception information of each vehicle C1 to CN while they are being powered by the chargers. The charging management system 100 can perform vehicle connection management to any or designated charger at base A by comparing the identification result of vehicles connected to each charger CH1 to CHM with the correspondence table TB11A or correspondence table TB11B. 【0165】 Furthermore, the charging management system 100 performs identification processing for vehicles connected to each charger CH1 to CHM during the time period until the charging connection deadline. This streamlines the process of reconnecting all vehicles that require charging between the charging connection deadline and the start of actual charging to the correct charger, even if there is an error in the charger connected to a vehicle. 【0166】 <Vehicle identification method using a time slot system> Next, an example of power supply processing and power reception confirmation processing using the time slot method will be described with reference to Figure 20. Figure 20 is a diagram showing an example of power supply processing and power reception confirmation processing using the time slot method. Note that the timetable shown in Figure 20 is just an example and is not limited to it. 【0167】 In the time-slot system, the integrated management system S1 supplies power to only one charger CH1-CHM during each time slot. Since only one vehicle receives power during each time slot in the time-slot system, the integrated management system S1 determines that a vehicle whose power supply status has been detected (confirmed) is connected to the charger to which power supply has been instructed. 【0168】 In the example shown in Figure 20, the integrated management system S1 instructs each of the chargers "Ch#01" to "Ch#04" to start supplying power every two minutes. The integrated management system S1 also identifies the vehicles connected to each charger "Ch#01" to "Ch#04" based on the power reception information of each vehicle C1 to CN acquired while the system is instructing the chargers to start supplying power. "Power reception confirmation" in the timetable indicates that the power reception status has been confirmed, that is, that the power reception status has been detected. 【0169】 <Vehicle identification method using handshake> Next, an example of power supply processing and power reception confirmation processing using the handshake method will be described with reference to Figure 21. Figure 21 is a diagram showing an example of power supply processing and power reception confirmation processing using the handshake method. Note that the timetable shown in Figure 21 is just an example and is not limited to it. 【0170】 In the handshake method, the integrated management system S1 first performs a power supply process to supply power to only one of the chargers CH1 to CHM during each time period. Then, when the vehicle's power reception status is confirmed and the connection pair between the vehicle and charger CH3 is identified, the next power supply process, along with the confirmation of the vehicle's power reception status and the identification of the connection pair between the vehicle and charger CH3, is initiated. 【0171】 In the example shown in Figure 21, the integrated management system S1 instructs charger "Ch#01" to start supplying power at time "17:00:01", identifies the vehicle connected to charger "Ch#01", and then instructs charger "Ch#02" to start supplying power at time "17:00:36", identifies the vehicle connected to charger "Ch#02". By repeating the same process, the integrated management system S1 can complete the identification process of connection pairs between all vehicles and chargers in a shorter time than the time slot method shown in Figure 20. 【0172】 As a result, the integrated management system S1 can perform the power supply process for the next charger and the identification process for the vehicle connected to that charger as soon as the identification process is completed. Therefore, the more chargers or vehicles installed at base A, the faster the integrated management system S1 can perform the identification process for all vehicles and chargers. 【0173】 Therefore, the charging management system 100 can complete the identification process for vehicles connected to each charger CH1-CHM in a shorter time, thereby increasing the time between the start of the identification process and the start of actual charging. In other words, the charging management system 100 allows the administrator to spend more time reconnecting all vehicles to the correct charger based on the identification results. This enables the charging management system 100 to more reliably connect all vehicles requiring charging to the charger before actual charging begins. 【0174】 <Vehicle identification method using binary code> Next, with reference to Figure 22, an example of power supply processing and power reception confirmation processing using a binary system will be described. Figure 22 is a diagram showing an example of power supply processing and power reception confirmation processing using a binary system. Note that the timetable shown in Figure 22 is just an example and is not limited to it. 【0175】 The binary charging management system 100 performs a time-division power supply process for each time period, supplying power to one or more chargers CH1 to CHM corresponding to the binary numbers. The integrated management system S1 identifies the connection pairs of vehicles C1 to CN connected to each charger CH1 to CHM based on the combination of power receiving states of each vehicle C1 to CN in each time period. 【0176】 The charging management system 100 determines, in a single identification process, the combination of chargers to be instructed to supply power to the M chargers CH1 to CHM installed at base A, using a pattern of binary 0s and 1s. Equation 1 is an equation for calculating the number of charger power supply patterns required to identify vehicles C1 to CN connected to each of the M chargers CH1 to CHM. 【0177】 【number】 【0178】 For example, if the number of chargers M=15, the number of power supply patterns is 4. The charging management system 100 assigns power supply patterns corresponding to binary 0s and 1s to each of the M chargers CH1 to CHM, as shown in Figure 22, and determines the combination of chargers that will be in a power supply state in each time slot. For example, the charging management system 100 powers chargers "Ch#08" to "Ch#15" at time t1, and powers chargers "Ch#04" to "Ch#07" and chargers "Ch#12" to "Ch#15" at time t2. 【0179】 As a result, the charging management system 100 can more effectively reduce the number of times the charger supplies power when identifying all vehicles C1 to CN connected to each charger CH1 to CHM, compared to the time slot method and the handshake method. Therefore, the integrated management system S1 can perform the identification process of connections between all vehicles and chargers in a shorter time, as the number of chargers or vehicles installed at base A increases. For example, consider the case where 15 chargers are installed, as shown in Figure 20, and the power supply time for one identification process is set to 2 minutes. In such a case, the charging management system 100 can reduce the identification process, which takes 2 minutes x 15 vehicles = 30 minutes using the time slot method, to 2 minutes x 4 patterns = 8 minutes by using the binary method. 【0180】 Therefore, the charging management system 100 can complete the identification process for vehicles connected to each charger CH1-CHM in a shorter time, thereby increasing the time between the start of the identification process and the start of actual charging. In other words, the charging management system 100 allows the administrator to spend more time reconnecting all vehicles to the correct charger based on the identification results. This enables the charging management system 100 to more reliably connect all vehicles requiring charging to the charger before actual charging begins. 【0181】 (Background leading to Embodiment 4) The charging management system 100 according to Embodiment 2 demonstrates an example of managing the system to ensure that all vehicles requiring charging are connected to an arbitrary or designated charger before the start of the main charging operation by displaying a charging management screen in real time that shows the current status of vehicles C1-CN and chargers CH1-CHM, thereby making misconnections of vehicles C1-CN visible to the administrator. However, if the operation is based on the premise that the main charging will be performed outside of business hours, the administrator or operator, such as a driver, may have to return to base A at night to correct the connection if a misconnection occurs between vehicles C1-CN and chargers CH1-CHN, or if they are unable to correct it, it may result in the need for emergency deliveries on the next day's delivery operations. Furthermore, in order to handle such nighttime corrections or to avoid disrupting the next day's delivery operations, operators are expected to take measures that lead to an increase in operational workload. However, an increase in operational workload presents the challenge of worsening the working environment or the Key Performance Indicators (KPIs) of the delivery business. 【0182】 Therefore, the charging management system 100A according to Embodiment 4 describes an example of an information processing method that, in addition to the functions that can be realized by one or more charging management systems 100 shown in Embodiments 1 to 3, more effectively suppresses the increase in operations for preventing misconnections and enables delivery services. In the following description, the same reference numerals are used for components that are the same as in Embodiments 1 to 3, and their descriptions are omitted. 【0183】 (Embodiment 4) First, an example of a use case for the charging management system 100A in this disclosure will be described. Figure 23 is a block diagram showing an example of the internal configuration of the charging management system 100A according to Embodiment 4. Note that the charging management system 100A shown in Figure 23 is just one example and is not limited thereto. Furthermore, the charging management system 100A shown in Figure 23 only illustrates an example of the internal configuration of the integrated management system S1A and the administrator terminal MPA as part of the charging management system 100A, and the internal configuration of other systems or devices is not shown. Also, for example, in this disclosure, from the viewpoint of ensuring the visibility of the drawings, reference numerals are used only for the main components in the description of each drawing, and even if a component has the same or substantially the same function as those described above in previously shown figures, a reference numeral may not be used. 【0184】 The charging management system 100A manages the charging of vehicles C1 to CN at a base A where M chargers CH1 to CHM are installed, each capable of charging N vehicles C1 to CN. The system calculates the next day's delivery plan for vehicles C1 to CN and the charging plan between vehicles C1 to CN and chargers CH1 to CHM. If it determines that the charger is not the predetermined connection destination, the system recalculates the next day's delivery plan based on whether it is possible to correct the misconnection between vehicles C1 to CN and chargers CH1 to CHM. The charging management system 100A includes an integrated management system S1A, a vehicle monitoring system S2, a charger management system S3, at least one driver terminal DP1 to DPN, and at least one administrator terminal MPA. 【0185】 The integrated management system S1A is connected to the vehicle monitoring system S2, the charger management system S3, and the driver terminals DP1-DPN and administrator terminal MPA via wired or wireless communication to transmit and receive data. The integrated management system S1A is a cloud server or on-premise server that performs charging management for vehicles C1-CN. The integrated management system S1A includes a communication unit 10, a processor 11A, and memory 12A. Each component is interconnected via a bus. 【0186】 The processor 11A is configured using, for example, a CPU or FPGA, and works in cooperation with the memory 12A to perform various processing and control. Specifically, the processor 11A refers to the programs and data held in the memory 12A and executes those programs to realize various functions of the integrated management system S1A. The various functions referred to here include some or more functions that the integrated management system S1 shown in Embodiments 1 to 3 can realize, as well as functions that each of the plan generation unit 111, connection confirmation unit 112, determination unit 113, and replanning unit 114 can realize. 【0187】 The planning generation unit 111 generates planning information 125 based on the delivery information 124 described later, which includes delivery planning information 125A to be executed using each of the vehicles C1 to CN, and charging planning information 125B to charge each of the vehicles C1 to CN. The charging planning information 125B includes the information from the correspondence tables TB11A and TB11B shown in Embodiment 1 (see Figures 8 and 9). 【0188】 The connection confirmation unit 112 uses the connection information between vehicles C1~CN and chargers CH1~CHM indicated by the charging plan information 125B of the generated plan information 125 as correct connection information to determine whether the connection status of chargers CH1~CHM to each vehicle C1~CN is correct, that is, whether it is not a misconnection. Based on this, the connection confirmation unit 112 performs a connection check between vehicles C1~CN and chargers CH1~CHM. The connection status of chargers CH1~CHM to each vehicle C1~CN, that is, the connection pair information, may be obtained by a known method or by the method shown in Embodiment 3. 【0189】 The determination unit 113 determines whether the connection between each vehicle C1-CN and charger CH1-CHM is correct, based on the connection status determination result by the connection confirmation unit 112. If the determination unit 113 determines that there is an incorrect connection, it also determines whether there is enough time to correct the incorrect connection. 【0190】 If the replanning unit 114 determines that it is not possible to correct all misconnections, it executes a replanning of the planning information 125. 【0191】 Memory 12A includes, for example, RAM as work memory used when executing each process of processor 11A, and ROM which stores programs and data that define the operation of processor 11A. Memory 12A may also include a storage device that includes either an SSD or an HDD. Data or information generated or acquired by processor 11A is temporarily stored in RAM. Programs that define the operation of processor 11A are written in ROM. If processor 11A executes some or all of the processes of processor 11, memory 12A may further include RAM used when executing some or all of the processes of processor 11, and ROM which stores programs and data that define some or all of the operation of processor 11. 【0192】 Memory 12A includes recovery constraint information 121, vehicle information 122, charger information 123, delivery information 124, planning information 125, connection pair information 126, replanning candidate information 127, and replanning information 128, etc. Memory 12A may further include the various types of information (various data) shown in Embodiments 1 to 3. 【0193】 The recovery constraint information 121 is information that indicates the working hours during which an operator can recover (correct) a misconnection in the connection between vehicles C1-CN and chargers CH1-CHM as set in the charging plan. For example, the recovery constraint information 121 includes at least the closing time information of the charging facility at base A (e.g., 20:00), or the operator's regular end time information according to their work rules (e.g., 18:00). Note that the end time information may differ depending on the operator's employment status (e.g., part-time, full-time, or contract employee). Furthermore, the end time information included in the recovery constraint information 121 is information that requires prior arrangements for work beyond the end time, and for which there is a monthly or annual limit on the period beyond the end time as stipulated by labor laws and regulations. 【0194】 Vehicle information 122 includes information about vehicles C1 to CN belonging to base A. For example, vehicle information 122 includes at least one of the following: the number of vehicles C1 to CN belonging to base A, identification information for each of vehicles C1 to CN, model, year of manufacture, purchase date, lease date, average driving range on a full charge, or remaining power. Vehicle information 122 is an example and is not limited thereto. 【0195】 Charger information 123 includes information about chargers CH1 to CHM installed at base A. For example, charger information 123 includes at least one of the following: the number of chargers CH1 to CHM, identification information for each of chargers CH1 to CHM, model, year of manufacture, purchase date, lease date, charging capacity (W), type, or installation location. The charging capacity (W) here is obtained by current (A) × voltage (V). The type indicates whether the charger is mobile (portable) or installed (fixed). The installation location usually indicates the parking lot location number, but may be other information that can identify the location of the charger. 【0196】 Delivery information 124 includes, for example, information about the customer of the delivery business and information about the delivery date or delivery time. Delivery information 124 may also include, in association with the customer's address, information regarding vehicle restrictions, information indicating the presence or absence of a waiting area at the delivery destination, waiting time, delivery method, and other conditions at the delivery destination. Furthermore, if the operator conducts a round-trip sales or maintenance without deliveries, delivery information 124 may replace information about deliveries with information about the visit. In such cases, delivery information 124 generally does not include information about deliveries. 【0197】 The planning information 125 includes delivery planning information 125A and charging planning information 125B. 【0198】 Delivery plan information 125A corresponds to delivery information 124 and includes information on the vehicle, driver, or delivery area that the vehicle will deliver to. Delivery plan information 125A may also include information such as delivery order, route, or delivery time slot. The delivery area referred to here is a district, divided by distance from the location of the delivery item's departure point or the location of the charger. In this disclosure, "district" may be referred to as "area." 【0199】 The charging plan information 125B includes the remaining charge of each vehicle C1 to CN, information on the charger used to charge each vehicle C1 to CN (i.e., the information in the correspondence tables TB11A and TB11B shown in Figures 8 and 9), the amount of charge to be charged in this charge, or information on the charging time for each vehicle C1 to CN. The charging plan information 125B may also refer to the information stored in the charger information 123 regarding information such as the performance of each charger CH1 to CHM. 【0200】 The connection pair information 126 is information about connection pairs between vehicles and chargers identified by known methods or by the method shown in Embodiment 3. The connection pair information 126 includes flag information regarding the presence or absence of connection errors for the planned connection between vehicles C1~CN and chargers CH1~CHM as indicated in the charging plan information 125B of the planning information 125. 【0201】 In Embodiment 4, the connection pair information 126 is described as independent information not linked to the charging plan information 125B, for the sake of clarity, but is not limited to this example. The connection pair information in the connection pair information 126 corresponds to the charging information (actual) included in the correspondence tables TB12A and TB12B (see Figures 8 and 9). The flag information regarding the presence or absence of connection errors in the connection pair information 126 corresponds to the checks that notify mismatches included in the correspondence tables TB12A and TB12B. Therefore, the connection pair information 126 may be information linked to the correspondence tables TB11A and TB11B included in the charging plan information 125B, or it may be the correspondence tables TB12A and TB12B themselves, generated by referring to the correspondence tables TB11A and TB11B (see Figures 8 and 9) in the charging plan information 125B. 【0202】 The replanning candidate information 127 is information on candidate delivery and charging plans obtained by replanning the delivery and charging plans. At least one replanning candidate information 127 is generated by the determination unit 113 when at least one misconnection is detected between vehicles C1~CN and chargers CH1~CHM, and this misconnection cannot be corrected. 【0203】 The replanning information 128 is the replanning candidate information selected by the administrator from among at least one replanning candidate information 127 generated by the determination unit 113. The replanning information 128 stores the selected replanning candidate information in the plan information 125 as new delivery plan information 125A and new charging plan information 125B. The replanning information 128 may include information such as the date and time, deadline, etc., when the plan information indicated by the replanning information 128 becomes effective. 【0204】 The administrator terminal MPA accepts selection operations from the administrator regarding the replanning candidate information 127 to be adopted as replanning information 128 from among the replanning candidate information 127 transmitted from the integrated management system S1A. The administrator terminal MPA includes a communication unit 20, a processor 21, a memory 22, a display 23, and an input unit 24. The administrator terminal MPA may further include a speaker (not shown) and be capable of outputting sound. 【0205】 The communication unit 20 is configured using a communication interface circuit for sending and receiving data or information between the integrated management system S1A and driver terminals DP1 to DPN deployed at the same location. The communication unit 20 transmits various information (data) output from the processor 21 to the integrated management system S1A or to the driver terminals DP1 to DPN. The communication unit 20 also outputs various information (data) corresponding to administrator operations received by the input unit 24 to the processor 21. 【0206】 The processor 21 is configured using, for example, a CPU or FPGA, and works in cooperation with the memory 22 to perform various processes and controls. Specifically, the processor 21 refers to the programs and data held in the memory 22 and executes those programs to realize various functions of the administrator terminal MPA. 【0207】 Memory 22 includes, for example, RAM as work memory used when executing each process of the processor 21, and ROM which stores programs and data that define the operation of the processor 21. Memory 22 may also include a storage device such as an SSD or HDD. Data or information generated or acquired by the processor 21 is temporarily stored in the RAM. The ROM contains programs that define the operation of the processor 21. 【0208】 The display 23 is constructed using, for example, a Liquid Crystal Display (LCD) or an organic electroluminescence (EL). The display 23 outputs a replanning screen SC41 (see Figure 32) that visualizes at least one replanning candidate information 127 transmitted from the integrated management system S1A, or any notifications transmitted from the integrated management system S1A, so that the administrator can view them. 【0209】 The input unit 24 detects the administrator's input operations, converts the content of the administrator's input operations into electrical signals, and outputs them to the processor 21. The input unit 24 is a user interface implemented by, for example, a keyboard, display, mouse, touch panel, etc., and performs dialogue processing with the administrator. Alternatively, the input unit 24 may be an AI agent that receives and responds to commands from the administrator through voice dialogue processing. 【0210】 Next, the delivery information 124 and planning information 125 will be explained with reference to Figure 24. Figure 24 shows an example of the delivery information 124 and planning information 125. Note that the delivery information 124 and planning information 125 shown in Figure 24 are just an example and are not limited thereto. 【0211】 The delivery information 124 shown in Figure 24, as an example, indicates the areas (districts) where deliveries will be made in the morning and afternoon of the following day. For example, the delivery information 124 shown in Figure 24 indicates that vehicle "EV#02" will deliver to destinations "A" and "B" in area "A2" in the morning of the following day, vehicle "EV#03" will deliver to destinations "C" and "D" in area "A2" in the morning of the following day, and vehicle "EV#04" will deliver to destination "D" in area "A2" in the afternoon of the following day. 【0212】 The delivery plan information 125A shown in Figure 24, as an example, shows the identification information of the delivery area (district), vehicle identification information, driver information, and delivery information 124 for each vehicle. The charging plan information 125B shown in Figure 24, as an example, shows the remaining charge level for each vehicle and the amount of charge to be charged at night (outside business hours) for each vehicle. 【0213】 For example, the delivery plan information 125A and charging plan information 125B shown in Figure 24 indicate a delivery plan for vehicle "EV#02" in which driver "D2" drives to delivery destinations "A" and "B" in area "A2", and a charging plan in which the current charge level is "18%" and the charger "Ch#01" will charge the vehicle to 100%. Similarly, the delivery plan information 125A and charging plan information 125B indicate a delivery plan for vehicle "EV#04" in which driver "D4" drives to delivery destination "D" in area "A2", and a charging plan in which the current charge level is "52%" and no charging will be performed by the charger (corresponding to "-" in Figure 24). 【0214】 <Procedure for replanning plan information> Next, with reference to Figure 25, an example of a replanning procedure for the planning information 125 will be described. Figure 25 is a flowchart showing an example of a replanning procedure for the delivery plan and charging plan of the integrated management system S1A according to Embodiment 4. 【0215】 The plan generation unit 111 generates plan information 125 (St61) based on the delivery information 124, which includes today's charging plan information 125B (charging plan) and tomorrow's delivery plan information 125A (delivery plan). The delivery plan information 125A of the plan information 125 may or may not include delivery route information. The delivery route is generated using an algorithm such as the traveling salesman problem. If the delivery plan information 125A does not include delivery route information, the delivery route is determined by driver operations received via the input unit 24 of the administrator terminal MPA. 【0216】 The connection confirmation unit 112 obtains the identification information of the charger from the charger that is charging and the identification information of the vehicle from the vehicle being charged via the charging cable. Based on the obtained identification information of the charger and the identification information of the vehicle, the connection confirmation unit 112 identifies the connection pair between the vehicle C1~CN and the charger CH1~CHM. The connection confirmation unit 112 uses the connection combination between the vehicle C1~CN and the charger CH1~CHM indicated by the charging plan information 125B of the generated plan information 125 as the correct connection pair, and performs a connection confirmation between the vehicle and the charger by determining whether the connection combination indicated by the identification result of the connection pair is correct (St62). 【0217】 The method for identifying the connection pair may be the method shown in Embodiment 3, or it may be a known method. For example, the method for acquiring vehicle identification information is not limited to via the charging cable; the charger may acquire it from the vehicle via a network such as wireless communication. Alternatively, for example, the method for acquiring vehicle identification information may be by image recognition of the vehicle's license plate or a QR code (registered trademark) printed on a sticker on the vehicle body using a camera built into the charger or accessible via a network. 【0218】 Here, the connection check performed in step St62 is carried out before the charging start time. The charging start time is the time when charging will be completed by the delivery start time the following day (for example, 9:00 a.m.). For example, if there are a total of 20 vehicles that require charging at the three charging facilities installed at base A, it is practical for the operator to perform connection checks at multiple times, since the time when each vehicle used for delivery returns to base A will be different. These multiple times could be, for example, 18:00, 19:00, 20:30, etc. 【0219】 The connection confirmation unit 112 compares the correct connection pair between the vehicle and charger indicated in the charging plan information 125B with the identification result of the connection pair. The connection confirmation unit 112 determines whether there is a connection pair that is different from the correct connection pair in the connection between the vehicles C1~CN and the chargers CH1~CHM. Based on the determination result, the connection confirmation unit 112 records the presence or absence of a connection pair (i.e., an incorrect connection) and the identification result of the connection pair between the vehicles C1~CN and the chargers CH1~CHM, as connection pair information 126, in the memory 12A. 【0220】 The determination unit 113 determines whether the connection status between the vehicles C1~CN and the chargers CH1~CHM is correct based on the connection pair information 126 (St63). 【0221】 If the determination unit 113 determines in step St63 that the connection status between vehicles C1~CN and chargers CH1~CHM is correct, that is, that there are no connection pairs different from the correct connection pair (St63, YES), it sends the plan information 125, including the latest delivery plan information 125A and charging plan information 125B, to the administrator terminal MPA and outputs (displays) it (St64). 【0222】 On the other hand, if the determination unit 113 determines in step St63 that the connection status between the vehicles C1~CN and the chargers CH1~CHM is incorrect, that is, that there is a connection pair different from the correct connection pair (St63, NO), it determines, based on the recovery constraint information 121, vehicle information 122, and charger information 123, etc., whether the operator can correct the incorrect connection before the charging start time, that is, whether the correction will be made in time (St65). 【0223】 For example, the determination unit 113 compares the current time with the closing time of the charging station and determines that if the current time exceeds the closing time of the charging station, it determines that the incorrect connection cannot be corrected. Alternatively, for example, the determination unit 113 may compare the current time with the operator's end time according to the delivery company's work rules and determine that if the current time exceeds the operator's end time, it determines that the incorrect connection cannot be corrected. Here, the end time is the regular working time or the time corresponding to late-night overtime (for example, 22:00). 【0224】 Furthermore, this disclosure provides an example in which the charging is performed at night (outside of business hours), but is not limited thereto. If the determination unit 113 determines, based on the delivery plan information 125A, that the incorrectly connected vehicle does not need to be charged and can be charged the following morning, it compares the start time of charging to charge the amount of remaining charge needed before delivery with the opening time of the charging station or the start time of work according to the work rules (e.g., 7:00), and determines whether the incorrect connection can be corrected. 【0225】 In step St65, if the operator determines that the misconnection can be corrected before the charging start time (St65, YES), the replanning unit 114 generates a notification to connect the vehicle that was determined to be misconnected to the correct charger destination and sends it to the administrator terminal MPA or the corresponding driver terminals DP1, ..., DPN. 【0226】 On the other hand, if the replanning unit 114 determines in step St65 that the operator cannot correct the misconnection by the charging start time (St65, NO), it generates one or more replanning candidate information 127 for the vehicle determined to be misconnected, by replanning the delivery plan information 125A and charging plan information 125B based on the delivery information 124 and connection pair information 126 (St66). The replanning unit 114 may use a brute-force method or the like as an example of the algorithm used to generate the replanning candidate information 127. 【0227】 The replanning unit 114 generates operation change information indicating the operational changes made by the replanning and adds it to the replanning candidate information 127 (St67). The operational change information is obtained by comparing the delivery plan information and charging plan information of the plan information 125 and the replanning candidate information 127, and indicates whether or not there are any changes for each of the area and driver sets, area and vehicle sets, and vehicle and driver sets. 【0228】 The replanning unit 114 sends (notifies) the administrator terminal MPA of one or more replanning candidate information 127 with the details of the operation changes added (St68). If there are multiple replanning candidate information 127, the replanning unit 114 generates and adds the details of the operation changes for each replanning candidate information 127. 【0229】 The administrator terminal MPA displays one or more replanning candidate information 127 transmitted from the integrated management system S1A on the display 23, making the replanning of the charging and delivery plans, and the content of the replanning visible to the administrator. The administrator terminal MPA accepts the administrator's selection operation via the input unit 24 for one or more replanning candidate information 127 to be adopted as the replanned charging and delivery plans. The administrator terminal MPA transmits the selected replanning candidate information 127 (i.e., the selection information) to the integrated management system S1A. 【0230】 The replanning unit 114 receives selection information sent from the administrator terminal MPA (St69). The replanning unit 114 generates replanning information 128, which changes the original charging plan and delivery plan to the charging plan and delivery plan of the replanning candidate information 127 indicated by the selection information, and records it in the memory 12, thereby replanning the charging plan and delivery plan (St70). 【0231】 The replanning unit 114 changes only the charging plan for the current day and the delivery plan for the following day to the charging plan and delivery plan of the replanning candidate information 127 indicated by the selection information. The replanning unit 114 also transmits the charging plan information 125B of the replanning information 128 to the corresponding chargers. As a result, chargers CH1 to CHM charge the vehicles connected to their chargers based on the transmitted charging plan information 125B. 【0232】 Furthermore, after the administrator terminal MPA sends the selection information to the integrated management system S1A, once the replanning process is complete, it displays (outputs) the replanning information 128 on the display 23 as the replanning information 128, which is the charging plan for the current day and the delivery plan for the following day, corresponding to the selected replanning candidate information 127 (St64). This allows the administrator to understand the delivery plan for the following day and contact the drivers during morning meetings, etc., or send information about the changed delivery plan for the following day to each of the driver terminals DV1 to DVN via email, etc. 【0233】 As described above, the integrated management system S1A in Embodiment 4 can determine whether an operator can correct a misconnection between vehicles C1-CN and chargers CH1-CHM, and based on the determination result, it can replan the charging plan for the day and the delivery plan for the next day. This enables the integrated management system S1A to carry out delivery operations the next day without the operator having to return to base A at night to correct the connection or being unable to correct the misconnection and thus disrupting the next day's delivery operations. 【0234】 Furthermore, in actual delivery operations, drivers become more familiar with the geography of a fixed delivery area by repeatedly delivering within that area, and they also build relationships with customers in that area. Therefore, it is desirable for drivers' delivery areas to be fixed and not changed daily. Also, vehicles have their own unique driving characteristics. Therefore, it is desirable for drivers to use the same vehicle. Moreover, depending on the delivery area (district), a vehicle suitable for driving is desirable; for example, a small car with good maneuverability is desirable in areas with many narrow alleys. Therefore, it is desirable for the vehicles used in each delivery area (district) to be fixed to vehicles with performance and type suitable for that delivery area (district), rather than being just any vehicle. 【0235】 Therefore, it is desirable for the integrated management system S1A to propose a delivery plan that takes into account the actual circumstances of the delivery operations described above. Accordingly, the integrated management system S1A in Embodiment 4 can realize a replanning that takes into account the actual circumstances of the delivery operations by proposing multiple different replanning candidate information and accepting a selection operation by the administrator. In addition, by receiving proposals for multiple different replanning candidate information, the administrator can receive a replanning proposal that is in line with the actual circumstances of the delivery operations. 【0236】 Next, we will specifically explain examples of replanning the delivery plan information 125A and the charging plan information 125B, referring to Figures 26 to 28. Figure 26 is a diagram showing an example of the delivery plan and charging plan before replanning. Figure 27 is a diagram showing an example of replanning the delivery plan and charging plan. Figure 28 is a diagram showing the contents of the replanning of the delivery plan and charging plan. 【0237】 The planning information PLN1 shown in Figure 26 is planning information that includes the delivery plan information and charging plan information before replanning. The planning information PLN1 includes the delivery plan information for the following day, for delivering goods to area "A2" using each of the vehicles C2 to C4 (corresponding to the identification information "EV#02" to "EV#04" shown in Figure 26). 【0238】 Furthermore, the planning information PLN1 includes charging planning information to charge vehicles C2 and C3, which have delivery plans for the following day, to 100% charge in this charge, in order to realize the delivery plans indicated by the delivery planning information performed by each of the vehicles C1 to C4 (corresponding to the identification information "EV#01" to "EV#04" shown in Figure 26). The charging planning information also includes information that the remaining charge of the vehicle with identification information "EV#02" corresponding to vehicle C2 is "18%", and the remaining charge of the vehicle with identification information "EV#03" corresponding to vehicle C3 is "32%". 【0239】 When the aforementioned planning information PLN1 is generated, the integrated management system S1A sends a notification requesting charging of vehicles C2 and C3 to the driver terminals DV2 and DV3 held by the drivers of vehicles C2 and C3, or to the administrator terminal MPA. 【0240】 The replanning candidate information PLN2 shown in Figure 27 is an example of replanning in a case where, due to a human error in connection, vehicle C1, which does not require charging, is being charged by charger CH1 instead of vehicle C2, which requires charging, and it is determined that this error in connection cannot be corrected. 【0241】 The replanning candidate information PLN2 shown in Figure 27 is the replanning candidate information 127 generated when vehicle C1, which does not require charging, is being charged by charger CH1 instead of vehicle C2, which does require charging. Since it is not possible to correct vehicle C1, which is misconnected and can be charged by charger CH1, the replanning candidate information PLN2 replans the charging plan to charge vehicles C1 and C3, which are currently connected to chargers CH1 and CH2 respectively, and replans the delivery plan to realize the next day's delivery plan using vehicles C1 and C3. 【0242】 Specifically, the rescheduling candidate information PLN2 includes charging plan information that modifies the vehicle C1 identification information "EV#01" to charge to "100%" during this charging session. In addition, the rescheduling candidate information PLN2 includes delivery plan information that modifies the delivery area (district) using the vehicle C1 identification information "EV#01" ("A1→A2"), and delivery information that includes delivery information to destinations "A" and "B" in the morning. 【0243】 The schematic diagram shown in Figure 28 shows the schematic diagram of the delivery plan information corresponding to the plan information PLN1 and the schematic diagram of the delivery plan information corresponding to the replanning candidate information PLN2. As shown in Figure 28, if the replanning candidate information PLN2 is adopted as the new plan information, the delivery plan will change the vehicle that delivers from Station 2, which represents base A, to delivery destinations A and B in area A2, which delivers on Mondays, Wednesdays, and Fridays, from the vehicle with identification information EV#02 to the vehicle with identification information EV#01. 【0244】 As described above, the charging management system 100A in Embodiment 4 eliminates the need for operators to correct the incorrect connection when the manager notices it during the working hours of the manager or an employee such as a driver, and can correct the incorrect connection, compared to when the manager notices the incorrect connection when the operator such as a manager or a driver is absent for reasons such as having left work, and the incorrect connection can be corrected by calling an employee. This eliminates the need for operators to correct the incorrect connection, more effectively suppressing the increase in man-hours and deterioration of the working environment, while enabling smooth next-day delivery. 【0245】 Next, we will explain examples of operational changes and replanning candidate information with reference to Figures 29 to 31. Figure 29 shows an example of replanning the delivery and charging plans (Example 1). Figure 30 shows an example of replanning the delivery and charging plans (Example 2). Figure 31 shows an example of replanning the delivery and charging plans (Example 3). 【0246】 The replanning candidate information PLN41, PLN42, and PLN43 shown in Figures 29 to 31 are examples of replanning generated based on the planning information PLN1 shown in Figure 26, when, due to a human error in connection, vehicle C1, which does not require charging, is being charged by charger CH1 instead of vehicle C2, which requires charging, and it is determined that this error cannot be corrected. Furthermore, the replanning candidate information PLN41 to PLN43 shown in Figures 29 to 31 will be described as examples that include information indicating delivery ("delivery") or information indicating no delivery ("-") as delivery information 124. In addition, the border lines FM41A, FM42A, FM43A and dashed lines FM41B, FM42B, FM43B shown in the replanning candidate information PLN41 to PLN43 are examples, and the line type, color, line thickness, etc., may be changed. 【0247】 The rescheduling candidate information PLN41 shown in Figure 29 includes a delivery plan in which vehicle C1, which was charged due to a misconnection, and its driver D1 are responsible for deliveries. The rescheduling candidate information PLN41 also includes a delivery plan in which vehicle C1 and its driver D1 are responsible for deliveries on the following day, replacing vehicle C2. In the rescheduling candidate information PLN41, driver D1 was responsible for deliveries in area "A1" in the delivery plan before the rescheduling, but the rescheduling will result in him being responsible for deliveries in area "A2". Note that the rescheduling candidate information PLN41 is the same as the delivery plan information and charging plan information as the rescheduling candidate information PLN2 shown in Figure 27. 【0248】 Furthermore, when the revised plan candidate information PLN41 is displayed on the administrator terminal MPA, it may include information such as a border line FM41A that highlights the information of vehicles whose plan information has been changed from the plan information PLN1, or dashed line FM41B that highlights the changed parts of the plan information that have been altered from the plan information PLN1. 【0249】 The operation change information IF41A shown in Figure 29 indicates that the set (combination) of delivery area (district) and the driver performing the delivery has been changed in the delivery plan information PLN1. In addition, the operation change information IF41A may further include information IF41B indicating whether or not the plan information PLN1 has been replanned. 【0250】 The rescheduling candidate information PLN42 shown in Figure 30 includes a delivery plan in which driver D2, who is normally in charge of vehicle C2, takes over the delivery of vehicle C1, which has been charged due to a misconnection. The rescheduling candidate information PLN42 also includes a delivery plan in which vehicle C1 is used instead of vehicle C2 for deliveries in area "A2", and the driver D2 of vehicle C2 drives vehicle C1 to handle deliveries the following day. In the rescheduling candidate information PLN42, driver D2 will perform deliveries in the same area "A2", but will be driving a different vehicle C1. 【0251】 Furthermore, when the revised plan candidate information PLN42 is displayed on the administrator terminal MPA, it may include information such as a border line FM42A that highlights the information of vehicles whose plan information has been changed from the plan information PLN1, or dashed line FM42B that highlights the changed parts of the plan information that have been altered from the plan information PLN1. 【0252】 The operation change information IF42A shown in Figure 30 indicates that the vehicle and driver set (combination) has been changed in relation to the delivery plan information PLN1. In addition, the operation change information IF42A may further include information IF42B indicating whether or not the plan information PLN1 has been replanned. 【0253】 The rescheduling candidate information PLN43 shown in Figure 31 includes a delivery plan in which driver D4, who is normally in charge of vehicle C4, takes over the delivery duties for vehicle C1, which has been charged due to a misconnection. The rescheduling candidate information PLN43 also includes a delivery plan in which vehicle C1 is used, and driver D4 of vehicle C4 drives vehicle C1 to handle the morning delivery of the following day, instead of the delivery of area "A2" which is normally done using vehicle C2. In the rescheduling candidate information PLN43, driver D4 will drive vehicle C1 in area "A2" to make the morning delivery, and then switch to vehicle C4 to make the afternoon delivery. 【0254】 Furthermore, when the revised plan candidate information PLN43 is displayed on the administrator terminal MPA, it may include information such as a border line FM43A that highlights the information of vehicles whose plan information has been changed from the plan information PLN1, or dashed line FM43B that highlights the changed parts of the plan information that have been altered from the plan information PLN1. 【0255】 The operation change information IF43A shown in Figure 30 indicates that the vehicle and driver set (combination) has been changed in relation to the delivery plan information in the planning information PLN1. In addition, the operation change information IF43A may further include information IF43B indicating whether or not the planning information PLN1 has been replanned. 【0256】 As described above, the integrated management system S1A in Embodiment 4 can propose to the administrator rescheduling candidate information PLN41 to PLN43, each containing a different delivery plan. The administrator can easily change the next day's plan information (rescheduling information 128) by comparing the proposed rescheduling candidate information PLN41 to PLN43 and selecting one of them. Specifically, the administrator compares the risk of driver D1 being assigned to deliveries in the unfamiliar area A2 in rescheduling candidate information PLN41, the risk of driver D2 driving the unfamiliar vehicle M1 in rescheduling candidate information PLN42, and the risk of driver D4 driving the unfamiliar vehicle M1 and also working long hours in the morning and afternoon in rescheduling candidate information PLN43, and selects one of the rescheduling candidate information. 【0257】 Next, the replanning screen SC41 for delivery and charging plans will be described with reference to Figure 32. Figure 32 is a diagram showing an example of the replanning screen SC41 for delivery and charging plans. Note that the replanning screen SC41 shown in Figure 32 is just one example and is not limited to this. 【0258】 The processor 21 of the administrator terminal MPA generates a replanning screen SC41 based on the replanning candidate information PLN41 transmitted from the integrated management system S1A and displays it on the display 23. Alternatively, the replanning screen SC41 may be generated by the integrated management system S1A. In this case, the administrator terminal MPA displays the replanning screen SC41 transmitted from the integrated management system S1A on the display 23. 【0259】 The replanning screen SC41 includes one or more replanning candidate information PLN41 from the integrated management system S1A, the operation change details IF41A attached to the replanning candidate information PLN41, the message Msg41, the toggle buttons SL41 and SL42, the select button BT41, and the deselect button BT42. 【0260】 The message Msg41 shown in FIG. 32, "There is a connection error and a replanning is proposed.
