  As shown in FIG. 1, the electric vehicle charging system according to the present embodiment is connected to charging stations 2 scattered in various places, and these charging stations 2 and existing mail servers 4 via a network 3 such as the Internet. Management server 1.

  The management server 1 provides a charging support service in response to requests from each charging station 2 and member users' wireless communication information terminals (for example, the mobile terminal 6 and the in-vehicle terminal 51).

  In order to perform such a function, the management server 1 has a hardware configuration as a computer (an external storage device, a memory, a CPU, an input device such as a keyboard, an output device such as a display, a network communication interface, etc.). The following functional configuration is realized by executing the installed predetermined program (Web server program, charging reservation management program, etc.). That is, as shown in FIG. 2A, the management server 1 includes a data storage unit 13 in which data to be described later necessary for providing the charging support service is stored, the charging station 2 and the wireless communication information terminals 6 of the member users. , 51 to return a document in response to a request from the server 51, an application unit 12 to execute various processes in response to an instruction from the server processing unit 11, and the operating state of the quick charger 21 in each charging station 2 And a reservation time notifying unit 15 for notifying member wireless communication information terminals 6 and 51 of the arrival of the reservation time of the charging station 2.

  The data storage unit 13 stores a user management database 131, a charging station management database 132, a charging reservation management database 133, and Web data 134.

  As shown in FIG. 3A, the user management database 131 includes account information (user ID, password) 1311 assigned to a member user for each member user who is provided with the charging support service. The e-mail address 1312 used in the terminals 6 and 51 and other information (member information) 1313 related to the member user are registered. The member information 1313 includes, for example, name information and contact information (address, telephone number, etc.) of the member user.

  In the charging station management database 132, as shown in FIG. 3B, for each charging station 2 to be managed, a station ID 1321 assigned to the charging station 2, position information 1322 indicating the location of the charging station 2, The operating status information 1323 indicating the operating status (normally operating or stopped) of the quick charger 21 of the charging station 2, the IP address 1324 of an operation panel 22 to be described later of the charging station 2, and the like are stored.

  In the charge reservation management database 133, as shown in FIG. 3C, a reservation information table 1331 is stored for each stand ID registered in the charge stand management database 132. In each reservation information table 1331, a reservation information record 1332 is registered for each reservation for the charging station 2 of the corresponding station ID. In the reservation information record 1332, the reservation ID 13321 assigned to the reservation, the user ID 13322 of the member user who made the reservation, reservation time information (charging start time, required charging time) 13323, and whether or not the reservation time is desired to be advanced. A carry forward flag 13324 is stored as reservation information.

  The Web data 134 includes a Web document for displaying various Web pages used in the charging support service on the wireless communication information terminals 6 and 51 of the member users. Examples of such Web pages include a new member user registration form and a login form that accepts input of account information of member users.

  The data shown here is an example, and other data may be stored in the data storage unit 13 as necessary.

  On the other hand, as shown in FIG. 1, each charging stand 2 includes a quick charger 21 for charging a battery mounted on the electric vehicle 5 and an operation panel 22 for the quick charger 21. Here, the operation panel 22 activates the quick charger 21 according to the operation of the member user, and requests the management server 1 to provide a charging support service.

  In order to fulfill such a function, the operation panel 22 has a hardware configuration as a computer having a wireless communication function that can be connected to the network 3 via a wireless access point (external storage device, memory, CPU, touch panel display, The following functional configuration is realized by executing an installed predetermined program (Web browser program, charger control program, etc.). That is, as shown in FIG. 2B, the operation panel 22 requests the charger controller 221 that controls the quick charger 21 and the management server 1 to provide a charge reservation support service and a reservation time arrival notification service. A client processing unit 222, an operation state reporting unit 223 that reports an operation state of the quick charger 21 in response to a periodic inquiry from the management server 1, and a Web page similar to the above used in the charging support service are displayed. And a data storage unit 224 in which a Web document to be stored is stored.

  Note that the wireless communication information terminals 6 and 51 of the member users are a Web client that requests the management server 1 to provide a charging support service by executing a predetermined program (Web browser, mailer program, etc.) installed, and an e-mail. What is necessary is just to implement | achieve the function as an e-mail client which transmits / receives.

  Prior to the description of the charging support service provided to the member users by the management server 1 in such an electric vehicle charging system, an update process of the charging station management database 132 used in this charging support service will be described.

  The operating state inquiry unit 14 of the management server 1 periodically inquires about the operating state of the quick charger 21 of each charging station 2. Specifically, all the IP addresses 1324 are read from the charging station management database 132, and the operation state of the quick charger 21 is inquired to the operation panel 22 of these IP addresses 1324.

  In response to this inquiry, the operating state reporting unit 223 of the operation panel 22 of each charging station 2 acquires the operating state (normally operating or stopped) of the quick charger 21 via the charger controller 221. Is reported to the management server 1, the operating state inquiry unit 14 updates the stand management database 132. Specifically, the operation status information 1323 associated with the stand ID of the charging station 2 is updated by an operation report (during normal operation or stopping) from the operation panel 22 of the charging station 2.

  As a result, the operating status information 1323 representing the latest operating status of the quick charger 21 of each charging station 2 is registered in the charging station management database 132.

Next, services included in the charging support service provided by the management server 1 (reservation time arrival notification service, charging reservation support service) will be described. Here, it is assumed that the member user who receives the charging support service has already completed user registration and has been given account information.
(1) Reservation time arrival notification service The reservation time notification unit 15 periodically checks the arrival of the charge reservation time entered by the member user, and notifies the fact by e-mail. Specifically, the reservation time notification unit 15 sets the user ID 13322 associated with the reservation time information 13323 at which the charging start time comes after a predetermined time (for example, after 5 minutes), in each reservation information table of the charge reservation management database 133. If the corresponding user ID 13322 is retrieved from the user management database 131, the electronic mail address 1312 associated with the user ID is read from the user management database 131. Then, an e-mail having a text indicating that the time for charging reservation comes after a predetermined time is generated, and this e-mail is transmitted to the e-mail address 1312 read at this time.

As a result, a member user who has made a reservation for charging at one of the charging stations 2 can know that his or her own charging order will be coming soon without waiting on the spot. It can be used effectively. It is also possible to prevent forgetting reservations and canceling without permission.
(2) Charging Reservation Support Service FIG. 4 is a flowchart showing the overall flow of the charging reservation support service.

  The member user enters his / her account information (user ID and password) in the input field in the login form on the display of the operation panel 22 of one of the charging stations (here, charging station 2-N). When the login button is touched, the client processing unit 222 of the operation panel 22 transmits an authentication request including the account information to the management server 1. Thereby, the user authentication based on the account information is performed in the management server 1 (S301). Specifically, in response to the authentication request, the server processing unit 11 passes the account information to the application unit 12 to instruct execution of user authentication, and the application unit 12 stores the account information 1311 that matches the account information. Search from the user management database 131.

  As a result, if the corresponding account information 1311 does not exist in the user management database 131 (authentication failure: NO in S302), the server processing unit 11 returns an authentication failure message to the operation panel 22. As a result, a message for prompting re-input of account information is displayed on the display of the operation panel 22.

  On the other hand, if the corresponding account information 1311 exists in the user management database 131 (authentication success: YES in S302), the server processing unit 11 issues a session ID and the session ID together with the user ID of the account information 1311. The authentication success message including the session ID is returned to the operation panel 22 while being temporarily held. This session ID is stored in the operation panel 22 and is added to subsequent requests from the operation panel 22 in order for the management server 1 to process a series of subsequent requests without going through the authentication process. Is not described in particular.

  If the user authentication is successful, the member user can thereafter receive the charge reservation support service at the charging station 2-N as shown below.

  When the quick charger 21 of the charging station 2-N is stopped due to a failure or the like (NO in S303), an operating charging station reservation service is provided to the member user by executing an operating charging station reservation process (S304) described later. . Thereby, the member user can make a charging reservation in the other charging station 2 in operation.

  On the other hand, when the quick charger 21 of the charging station 2-N is operating normally (YES in S303), the client processing unit 222 of the operation panel 22 reads a predetermined Web document from the data storage unit 224, and this Web document The top menu represented by is displayed on the display (S305). In this top menu, a charge button and a reservation cancel button are arranged as menu item buttons.

  Here, if no menu item button is selected within a predetermined time, the client processing unit 222 of the operation panel 22 is logged out of the management server 1 due to a timeout, and the initial screen (login form) is displayed again on the display. indicate. On the other hand, if any menu item button is selected within a predetermined time, a service corresponding to the operated menu item button is provided to the member user as shown below.

  If the menu item button selected on the top menu is a reservation cancel button (“reservation cancel” in S306), a reservation cancel service is provided to the member user by executing a reservation cancel process (S307) described later. Thereby, the member user can cancel the charge reservation put in charge stand 2-N or other charge stand 2. FIG.

  On the other hand, if the menu item button selected on the top menu is a charge button (“charge” in S306), the client processing unit 222 of the operation panel 22 reads a predetermined Web document from the data storage unit 224, and this Web document The submenu represented by is displayed on the display (S308). In this submenu, a reservation button, a reserved button, and an early charging button are arranged as menu item buttons.

  Here, if no menu item button is selected within a predetermined time, the client processing unit 222 of the operation panel 22 is logged out of the management server 1 due to a timeout, and the initial screen (login form) is displayed again on the display. indicate. On the other hand, if any menu item button is selected within a predetermined time, a service corresponding to the operated menu item button is provided to the member user as shown below.

  When the menu item button selected on the submenu is a reservation button (“Reservation” in S309), a charge reservation service is provided to the member user by executing a charge reservation process (S310) described later. Thereby, the member user can enter a charging reservation for the charging station 2-N.

  If the menu item button selected on the submenu is a reserved button (“Reserved” in S309), the client processing unit 222 of the operation panel 22 confirms the reservation including the stand ID of the charging station 2-N. A request is transmitted to the management server 1. Thereby, the charge reservation confirmation of the member user is performed in the management server 1 (S311). Specifically, in response to the reservation confirmation request, the server processing unit 11 causes the application unit 12 to store the user ID associated with the session ID (hereinafter, the retained user ID) and the charging station 2-N. The stand ID is passed to instruct execution of the charge reservation confirmation. In response to this instruction, the application unit 12 reads the reservation information including the reservation time information 13323 at which the charging start time comes first from the reservation information table 1331 corresponding to the stand ID of the charging station 2-N. The user ID 13322 included in the user ID is compared with the passed user ID.

  As a result, if the two match, the server processing unit 11 returns a chargeable notification including the reservation ID 13321 and the reservation time information 13323 included in the read reservation information to the operation panel 22. On the other hand, if the two do not match, the application unit 12 reads the reservation ID 13321 and reservation time information 13323 associated with the passed user ID from the reservation information table 1331 corresponding to the stand ID of the charging station 2-N. . Then, the server processing unit 11 returns a charge impossible notification including the reservation ID 13321 and the reservation time information 13323 read at this time to the operation panel 22.

  After that, when the client processing unit 222 of the operation panel 22 accepts the chargeable notification, it displays on the display a charging guidance message indicating that charging for the required charging time of the reserved time information 13323 included in the chargeable notification is possible. To do. In addition, when a notification indicating that charging is not possible is accepted, a turn waiting guidance message indicating that charging is possible in the time zone indicated by the reservation time information 13323 included in the notification that charging is possible is displayed on the display (S312).

  If the menu item button selected on the submenu is an early charge button (“early charge” in S309), the member user can execute the charge order adjustment process (S315), which will be described later, to charge the charging station 2-N. You can make a charge reservation at the earliest available time. If there is no waiting time at this time (YES in S316), the client processing unit 222 of the operation panel 22 displays a charging guidance message indicating that charging is possible immediately on the display (S317).

  When the member user charges the battery mounted on the electric vehicle 5 for a time corresponding to the time required for charging in accordance with the charging guidance message displayed in S312 or S317 (S313), the client processing unit 222 of the operation panel 22 is charged. A charging completion notification including the stand ID and reservation ID of the stand 2-N is transmitted to the management server 1. When the server processing unit 11 of the management server 1 accepts the notification of completion of charging, it passes the stand ID and reservation ID of the charging station 2-N to the application unit 12 to instruct reservation deletion. In response to this instruction, the application unit 12 deletes the reservation information record 1332 including the passed reservation ID 13321 from the reservation information table 1331 corresponding to the stand ID of the charging station 2-N (S314).

  Next, each processing (reservation cancellation processing (S307), charging reservation processing (S310), active charging stand reservation processing (S304), charging order adjustment processing (S315) executed in the process of providing the charging reservation support service shown in FIG. )) Will be explained.

  FIG. 5 is a flowchart of the reservation cancellation process (S307) shown in FIG.

  First, the client processing unit 222 of the operation panel 22 transmits a reservation confirmation request to the management server 1 (S401).

  In response to this reservation confirmation request, the server processing unit 11 of the management server 1 instructs the application unit 12 to execute the charge reservation confirmation. In response to this instruction, the application unit 12 searches the charge reservation management database 133 for a reservation information record 1332 including a user ID 13322 that matches the stored user ID (S451).

  As a result, if the corresponding reservation information record 1332 does not exist in any reservation information table 1331 (NO in S452), the server processing unit 11 notifies the operation panel 22 that the reservation search has failed (S453). ). Upon receiving this notification (No in S402), the client processing unit 222 of the operation panel 22 displays a message on the display indicating that no charging station 2 is reserved for charging.

  On the other hand, if the corresponding reservation information record 1332 exists in any of the reservation information tables 1331 (YES in S452), the server processing unit 11 stores the reservation information (reservation ID, reservation ID, A Web document that displays a user ID, a reservation time, whether there is advance advance) and a stand ID corresponding to the reservation information table 1331 in which the reservation information record 1332 is registered is returned to the operation panel 22 (S454).

  When the client processing unit 222 of the operation panel 22 receives the Web document returned from the management server 1 (YES in S402), the reservation content confirmation page represented by the Web document is displayed on the display (S403). On this reservation content confirmation page, reservation information and a stand ID are displayed, and a reservation cancel confirmation button is arranged.

  If the member user selects the reservation cancel confirmation button within a predetermined time (YES in S404), the client processing unit 222 of the operation panel 22 displays the stand ID displayed on the reservation content confirmation page and the reservation ID of the reservation information. A reservation cancellation request including “” is transmitted to the management server 1 (S405).

  When the server processing unit 11 of the management server 1 receives this reservation cancellation request (YES in S455), it passes the received stand ID and reservation ID to the application unit 12 to instruct reservation deletion. In response to this instruction, the application unit 12 deletes the reservation information record 1332 including the passed reservation ID 13321 from the reservation information table 1331 corresponding to the passed stand ID (S456).

  Thereafter, the server processing unit 11 returns a reservation cancellation completion notification to the operation panel 22 (S457). As a result, a message indicating that the charge reservation has been canceled is displayed on the display of the operation panel 22 (S406).

  In addition, the application unit 12 sets, from the reservation information table 1331 corresponding to the passed stand ID, reservation time information 13323 whose charging start time comes later than the charging start time of the reservation time information 13323 of the deleted reservation information record 1332 , Among the user IDs 13322 associated with the advance request flag 13324 indicating “present”, the user ID 13322 associated with the reservation time information 13323 with the earliest charge start time is read out and associated with this user ID. The e-mail address 1312 is further read from the user management database 131. At this time, the user ID read from the reservation information table 1331 has a charge start time later than the charge start time of the reservation time information 13323 of the deleted reservation information record 1332 and the reservation time of the deleted reservation information record 1332 Reservation time information with the earliest charge start time among the user ID 13322 associated with the reservation time information 13323 in which the charge required time falls within the charge required time of the information 13323 and the advance request flag 13324 indicating “present” It may be associated with 13323.

  Then, an e-mail having a text indicating that a free time has occurred in the time zone indicated by the reservation time information 13323 included in the deleted reservation information record 1332 is generated and transmitted to the e-mail address read at this time ( S458). As a result, the member user waiting for the charge order who wants to advance the reservation can know that the idle time has occurred before his / her charge reservation, so by operating the early charge button on the submenu Charge reservation can be advanced.

  6 and 7 are flowcharts of the charge reservation process (S310) shown in FIG.

  First, the client processing unit 222 of the operation panel 22 reads a predetermined Web document from the data storage unit 224 and displays a reservation status confirmation page represented by the Web document on the display. On this reservation status confirmation page, there are arranged input fields for a required charging time and a desired reservation time zone, and a reservation status confirmation button. In this reservation status confirmation page, when the member user inputs the required charging time and the desired reservation time zone in each input field and touches the reservation status confirmation button (S501), the client processing unit 222 of the operation panel 22 inputs each input. A reservation status confirmation request including field input data (required charging time and desired reservation time zone) and a stand ID of the charging station 2-N is transmitted to the management server 1 (S502).

  In response to the reservation status confirmation request, the server processing unit 11 of the management server 1 passes the held user ID, the stand ID of the charging station 2-N, the charging required time, and the desired reservation time zone to the application unit 12. Instructs execution of reservation status confirmation. In response to this instruction, the application unit 12 uses the reservation information table 1331 corresponding to the stand ID of the charging station 2-N, and reservation information including reservation time information 13323 representing a time zone included in the desired reservation time zone. (Reservation information within the desired reservation time zone) is searched. Further, the reservation information table 1331 of all charging stations 2 is searched for reservation information (hereinafter referred to as member user reservation information) including a user ID 13322 that matches the received user ID being held (S551).

  At this time, if the member user reservation information is searched (reserved: YES in S552), the server processing unit 11 returns a reserved message including the stand ID included in the member user reservation information to the operation panel 22 (S553). ). As a result, a message indicating that the charging station 2 having the stand ID included in the reserved message has been reserved by the member user is displayed on the display of the operation panel 22.

  On the other hand, if the member user reservation information is not searched (unreserved: NO in S552), the application unit 12 displays a time zone other than the time zone indicated by the reservation time information 13323 of all the searched reservation time zone reservation information. Are extracted from the desired reservation time zone as free time zones (S554).

  If there is no free time zone that is equal to or longer than the required charge time in the free time zone extracted at this time (reservation is impossible: NO in S555), the server processing unit 11 has a free time that can be reserved in the desired reservation time zone. A message indicating that there is no message is returned to the operation panel 22 (S556). Thereby, a message to that effect is displayed on the reservation status confirmation page on the display of the operation panel 22 (NO in S505, S506).

  Also, if there is a free time zone that exceeds the required charge time in the free time zone extracted in S554 (reservation is possible: YES in S555), the free time zone that is longer than the required charge time is divided into the required charge time units. A Web document displaying the free time list is returned to the operation panel 22 (S557).

  When the client processing unit 222 of the operation panel 22 receives the Web document returned from the management server 1 (YES in S505), the reservation page represented by the Web document is displayed on the display (S507). On this reservation page, a free time list is displayed, and a reservation advance request button and a reservation confirmation button for accepting an advance reservation time advance are arranged.

  In this reservation page, the member user selects any available time from the available time list as a reserved time, selects a reservation advance request button as necessary (S508), and touches the reservation confirmation button (S509). ), The client processing unit 222 of the operation panel 22 issues a reservation registration request including the stand ID of the charging station 2-N, the selected reservation time, and the state of the reservation advance request button (whether or not advance reservation time is desired). It transmits to the management server 1 (S510).

  In response to this reservation registration request, the server processing unit 11 of the management server 1 gives the application unit 12 execution of reservation registration by passing the stand ID of the charging station 2-N, the reservation time, and the state of the reservation advance request button. To do. In response to this instruction, the application unit 12 adds a new reservation information record 1332 to the reservation information table 1331 corresponding to the stand ID of the charging station 2-N, and sets reservation information (new reservation ID 13321, The held user ID 13322, reservation time information 13323 indicating the passed reservation time, and the advance request flag 13324 corresponding to the state of the passed reservation advance request button are registered (S558). Thereafter, the server processing unit 11 returns a reservation registration completion notification including the registered reservation information to the operation panel 22 (S559).

  As a result, a message indicating that the charge reservation is completed and the registered reservation information are displayed on the display of the operation panel 22 (S511).

  8 and 9 are flowcharts of the active charging station reservation process (S304) shown in FIG.

  First, the client processing unit 222 of the operation panel 22 reads a predetermined Web document from the data storage unit 224, and displays an operation stand search menu represented by the Web document on the display (S601). In this operating stand search menu, a distance priority search button and a time priority search button are arranged as menu item buttons. Here, if no menu item button is selected within a predetermined time, the client processing unit 222 of the operation panel 22 is logged out of the management server 1 due to a timeout, and the initial screen (login form) is displayed again on the display. indicate. On the other hand, if any menu item button is selected within a predetermined time, an active charging station search service corresponding to the operated menu item button is provided to the member user as shown below.

  If the menu item button selected on the operating charging stand search menu is a time priority search button (“time priority” in S602), the client processing unit 222 of the operation panel 22 retrieves a predetermined Web document from the data storage unit 224. The operation charging station reservation status confirmation page (time priority) represented by this Web document is displayed on the display. On this operating charging stand reservation status confirmation page, there are arranged input fields for a required charging time and a desired reservation time zone, and a reservation status confirmation button.

  In this operation charging station reservation status confirmation page (time priority), when the member user inputs the required charging time and the desired reservation time zone in each input field and touches the reservation status confirmation button (S603), the client of the operation panel 22 The processing unit 222 transmits to the management server 1 an active charging station search request (time priority) including input data (required charging time and desired reservation time zone) of each input field and a stand ID of the charging station 2-N (S604). ).

  On the other hand, if the menu item button selected on the operating charging stand search menu is a distance priority search button (“distance priority” in S602), the client processing unit 222 of the operation panel 22 receives a predetermined Web from the data storage unit 224. The document is read, and the active charging station reservation status confirmation page (distance priority) represented by the Web document is displayed on the display. In this operation charging station reservation status confirmation page (distance priority), each input field of the required charging time and the desired search distance range (maximum distance from the charging station 2-N to the desired charging station), reservation status confirmation Button is arranged.

  In this operation charging station reservation status confirmation page (distance priority), when the member user inputs the required charging time and the search desired distance range in each input field and touches the reservation status confirmation button (S605), the client of the operation panel 22 The processing unit 222 transmits an operation charging station search request (distance priority) including input data (required charging time and desired search distance range) of each input field and a stand ID of the charging station 2-N to the management server 1 (S606). ).

  When the server processing unit 11 of the management server 1 receives an active charging stand search request (time priority) from the operation panel 22 (“time priority” in S651), the application unit 12 sends a stand for the charging station 2-N. The ID, the required charging time, and the desired reservation time zone are passed to instruct execution of the operating charging station search (time priority). In response to this instruction, the application unit 12 retrieves the position information 1322 associated with the stand ID of the charging station 2-N from the charging station management database 132, and corresponds to the operation status information 1323 representing “normally operating”. All of the attached stand ID 1321 and position information 1322 are extracted from the charging stand management database 132 as the stand ID and position information of the operating charging stand (S652).

  Furthermore, an empty time zone is extracted for each stand ID of each active charging station 2 (S653). Specifically, the reservation time information 13323 representing the time zone included in the desired reservation time zone is searched from the reservation information table 1331 corresponding to the stand ID of the operating charging station 2, and the time indicated by the searched reservation time information 13323 is retrieved. All the time zones other than the time zone are extracted from the desired time zone as a free time zone.

  If there is no free time zone that is longer than the required charge time in any free time zone extracted at this time (reservation is impossible: NO in S654), the server processing unit 11 can perform an operation that can be reserved in the desired reservation time zone. A message indicating that there is no charging station is returned to the operation panel 22 (S656). As a result, a message to that effect is displayed on the active charging station reservation status confirmation page (time priority) on the display of the operation panel 22 (NO in S607, S608).

  On the other hand, if the free time zone extracted in S653 includes a free time zone that is equal to or longer than the required charging time (reservation is possible: YES in S654), the free time zone that is equal to or longer than the required charging time, the stand ID of the active charging station, and A Web document that generates a list in which correspondence information with position information is arranged in the order of position information representing a position close to the position represented by the position information 1322 of the charging station 2-N, and displays this list as a free time list that can be reserved Is returned to the operation panel 22 (S655). The client processing unit 222 of the operation panel 22 displays the reserved page represented by the Web document on the display (YES in S607, S609). On this reservation page, a list of available free times is displayed, and a reservation advance button and a reservation confirmation button for accepting an advance request for reservation time are arranged.

  In addition, when the server processing unit 11 of the management server 1 receives an active charging stand search request (distance priority) from the operation panel 22 (“distance priority” in S651), the application unit 12 receives the stand ID of the charging station 2-N. Instructing the execution of the active charging stand search (distance priority) by passing the required charging time and the desired search distance range. In response to this instruction, the application unit 12 extracts the position information 1322 associated with the stand ID 1321 of the charging station 2-N from the charging station management database 132, and from the position represented by the position information 1322 of the charging station 2-N. The position information 1322 representing the position within the range of the desired search distance and associated with the operation status information 1323 representing “normally operating”, and the stand ID 1321 associated with the position information 1322 are All the charging station position information and the stand ID are extracted from the charging station management database 132 (S657).

  Furthermore, an empty time zone is extracted for each stand ID of each active charging station 2 (S658). Specifically, the reservation time information 13323 is searched from the reservation information table 1331 associated with the stand ID of the operating charging station 2, and a time zone other than the time zone indicated by the searched reservation time information 13323 is set as a free time zone. Extract all as.

  If there is no free time zone that is longer than the required charge time in the free time zone extracted at this time (reservation is impossible: NO in S654), the server processing unit 11 has an active charging station that can be reserved in the desired search distance range. A message to that effect is returned to the operation panel 22 (S656). Accordingly, a message to that effect is displayed on the active charging stand reservation status confirmation page (distance priority) on the display of the operation panel 22 (NO in S607, S608).

  On the other hand, if there is a free time zone greater than the required charge time in the free time zone extracted in S658 (reservation is possible: YES in S654), the free time zone greater than the required charge time is divided into required charge time units. The operation panel 22 generates a list in which correspondence information between the idle time and the stand ID and the position information of the active charging station is arranged in the order of the available idle time, and this list is displayed as an available idle time list. (S655). The client processing unit 222 of the operation panel 22 displays the reserved page represented by the Web document on the display (YES in S607, S609). On this reservation page, a list of available free times is displayed, and a reservation advance button and a reservation confirmation button for accepting an advance request for reservation time are arranged.

  In the reservation page, when the member user selects any available time from the available free time list as the reserved time, selects a reservation advance request button as necessary, and touches the reservation confirmation button (S610). Then, a reservation registration request including the selected reservation time, the corresponding stand ID, and the state of the reservation advance request button (whether or not advance reservation time is desired) is transmitted to the management server 1 (S611).

  In response to the reservation registration request, the server processing unit 11 of the management server 1 passes the received stand ID, reservation time, and reservation advance request button state to the application unit 12 to instruct execution of reservation registration. In response to this instruction, the application unit 12 adds a new reservation information record 1332 to the reservation information table 1331 corresponding to the passed stand ID, and the reservation information (new reservation ID 13321, held in the new reservation information record 1332). User ID 13322, reservation time information 13323 representing the passed reservation time, and advance request flag 13324 corresponding to the state of the passed reservation advance request button are registered (S659). Thereafter, the server processing unit 11 returns a reservation registration completion notification including the registered reservation information to the operation panel 22 (S660). As a result, a message indicating that the reservation has been completed and the registered reservation information are displayed on the display of the operation panel 22 (S612).

  When the registration of new reservation information is completed in this way, the application unit 12 is a reservation information record 1332 having a user ID 13322 being held from the reservation information table 1331 corresponding to the stand IDs of all charging stations 2, The reservation information record 1332 other than the new reservation information record 1332 registered in S659 (referred to as the old reservation information record 1332) is searched (S661). If the old reservation information record 1332 exists (YES in S661), the application unit 12 deletes the old reservation information record 1332 from the reservation information table 1331 corresponding to the stand IDs of all charging stations 2 (S662). That is, when the member user who has made a charge reservation in the idle time is a member user waiting for the charge order who knows the occurrence of the idle time by e-mail, the old charge reservation of the member user is canceled.

  Then, from the reservation information table 1331 from which the old reservation information record 1332 is deleted, the reservation time information 13323 whose charging start time comes later than the charge start time of the reservation time information 13323 of the deleted old reservation information record 1332 is “present”. The user ID 13322 associated with the reservation time information 13323 with the earliest charge start time is read out from the user ID 13322 associated with the advance request flag 13324 indicating the e-mail address associated with this user ID. 1312 is read from the user management database 131. At this time, the user ID read from the reservation information table 1331 has a charge start time later than the charge start time of the reservation time information 13323 of the deleted reservation information record 1332 and the reservation time of the deleted reservation information record 1332 Reservation time information with the earliest charge start time among the user ID 13322 associated with the reservation time information 13323 in which the charge required time falls within the charge required time of the information 13323 and the advance request flag 13324 indicating “present” It may be associated with 13323.

  Then, an e-mail having a text indicating that a free time has occurred in the time zone indicated by the reservation time information 13323 included in the deleted old reservation information record 1332 is generated and transmitted to the e-mail address read at this time (S663). As a result, each time a vacant time occurs due to the advance of the charge reservation of another member user waiting for the charge order, the member user waiting for the charge order who wishes to advance the reservation at the same charge stand will Since it is possible to know that a free time has occurred, the charge reservation can be advanced by operating the early charge button on the submenu.

  FIG. 10 is a flowchart of the charging order adjustment process (S315) shown in FIG.

  First, the client processing unit 222 of the operation panel 22 reads a predetermined Web document from the data storage unit 224 and displays a waiting status confirmation page represented by the Web document on the display. On this waiting status confirmation page, an input field for a required charging time and a waiting status confirmation button are arranged. In this waiting status confirmation page, when the member user inputs the required charging time in the input field and touches the waiting status confirmation button (S701), the client processing unit 222 of the operation panel 22 causes the input field (charging required) to be input. Time) and the waiting status confirmation request including the stand ID of the charging station 2-N are transmitted to the management server 1 (S702).

  In response to this waiting state confirmation request, the server processing unit 11 of the management server 1 instructs the application unit 12 to execute the waiting state confirmation by passing the stand ID of the charging station 2-N and the required charging time. In response to this instruction, the application unit 12 reads from the reservation information table 1331 corresponding to the stand ID of the charging station 2-N the reservation time information 13323 at which the charge disclosure time comes first, and starts the charging start time from the current time. It is determined whether or not there is a free time for the required charging time.

  As a result, if there is no free time corresponding to the required charging time from the current time to the charging start time (YES in S751), it is determined that there is a waiting time, and otherwise (from the current time to the charging start time). If there is a free time corresponding to the required charging time, or if the reservation information record 1332 is not registered in the reservation information table 1331 (NO in S751), it is determined that there is no waiting time.

  If it is determined that there is no waiting time (NO in S751), the application unit 12 adds a new reservation information record 1332 to the reservation information table 1331 corresponding to the stand ID of the charging station 2-N, and this new reservation information record Reservation information (new reservation ID 13321, holding user ID 13322, reservation time information 13323 represented by the current time and required charging time, and advance request flag 13324 indicating reservation advance request “none”) is registered in 1332 (S752). ).

  On the other hand, when it is determined that there is a waiting time (YES in S751), the application unit 12 starts the first charging time longer than the time period indicated by the reservation time information 13323 and the time period indicated by the next reservation time information 13323. Until the vacant time (referred to as the earliest vacant time) is detected, the charging start time arrives from the reservation information table 1331 corresponding to the stand ID of the charging station 2-N while counting the number of times of reading the reservation time information 13323. The reservation time information 13323 is read out in order from the earliest. If the earliest available time is detected, a Web document that displays the number of times the reserved time is read as the number of people waiting for charging and the time from the current time to the start time of the earliest available time is returned to the operation panel 22. When the next reservation time information 13323 cannot be retrieved from the reservation information table 1331, the number of reading of the reservation time information 13323 is set as the number of people waiting for charging, and the time zone indicated by the last reservation time information 13323 from the current time. A Web document that displays the time until the end time (start time of the first available time that is equal to or longer than the required charge time, that is, the start time of the first available time) as a charge waiting time is returned to the operation panel 22 (S753).

  The client processing unit 222 of the operation panel 22 displays the front free time reservation page represented by the Web document returned from the management server 1 on the display (S703). In the forefront vacant time, the number of people waiting for charging and the charging waiting time are displayed, and a reservation advance request button and a reservation confirmation button for accepting an advance request for reservation time are arranged. When the member user selects a reservation advance button as necessary on this reservation screen and touches the reservation confirmation button (S704), the client processing unit 211 of the operation panel 22 displays the stand ID of the charging station 2-N, Then, a request for registration of the most recent free time reservation including the state of the reservation advance request button (whether or not advance reservation time is desired) is transmitted to the management server 1 (S705).

  In the management server 1, the server processing unit 11 passes the stand ID of the charging station 2 -N and the state of the reservation advance request button to the application unit 12 in response to the request for registration of the latest available time reservation. Is instructed to execute. In response to this instruction, the application unit 12 adds a new reservation information record 1332 to the reservation information table 1331 corresponding to the stand ID of the charging station 2-N, and sets reservation information (new reservation ID 13321, The user ID 13322 being held, the reservation time information 13323 represented by the start time of the earliest available time and the required charging time, and the advance request flag 13324 corresponding to the state of the advance reservation button are registered (S754). Thereafter, the server processing unit 11 returns a reservation registration completion notification including the reservation information registered at this time to the operation panel 22 (S755). As a result, a message indicating that the charge reservation is completed and the registered reservation information are displayed on the display of the operation panel 22 (S706).

  When the registration of new reservation information is completed in this way, the application unit 12 is a reservation information record 1332 having a user ID 13322 being held from the reservation information table 1331 corresponding to the stand IDs of all charging stations 2, The reservation information record 1332 (referred to as the old reservation information record 1332) other than the new reservation information record 1332 registered in S752 and S754 is searched (S756). If the old reservation information record 1332 exists (YES in S756), the application unit 12 deletes the old reservation information record 1332 from the reservation information table 1331 corresponding to the stand IDs of all charging stations 2 (S757). That is, when the member user who has made a charge reservation in the idle time is a member user waiting for the charge order who knows the occurrence of the idle time by e-mail, the old charge reservation of the member user is canceled.

  Then, from the reservation information table 1331 from which the old reservation information record 1332 is deleted, the reservation time information 13323 whose charging start time comes later than the charge start time of the reservation time information 13323 of the deleted old reservation information record 1332 is “present”. The user ID 13322 associated with the reservation time information 13323 with the earliest charge start time is read out from the user ID 13322 associated with the advance request flag 13324 indicating the e-mail address associated with this user ID. 1312 is read from the user management database 131. At this time, the user ID read from the reservation information table 1331 has a charge start time later than the charge start time of the reservation time information 13323 of the deleted reservation information record 1332 and the reservation time of the deleted reservation information record 1332 Reservation time information with the earliest charge start time among the user ID 13322 associated with the reservation time information 13323 in which the charge required time falls within the charge required time of the information 13323 and the advance request flag 13324 indicating “present” It may be associated with 13323.

  Then, an e-mail having a text indicating that a free time has occurred in the time zone indicated by the reservation time information 13323 included in the deleted old reservation information record 1332 is generated and transmitted to the e-mail address read at this time (S758). As a result, each time a vacant time occurs due to the advance of the charge reservation of another member user waiting for the charge order, the member user waiting for the charge order who wishes to advance the reservation at the same charge stand will Since it is possible to know that a free time has occurred, the charge reservation can be advanced by operating the early charge button on the submenu.

  The present embodiment has been described above.

  According to the charging reservation support service according to the present embodiment, a member user who has made a charging reservation in one of the charging stations 2 will soon be in charge of his or her own charging order without waiting on the spot. Therefore, it is possible to effectively use the charging waiting time. This reduces the burden on the driver who uses the charging stand. In addition, since it is possible to prevent forgotten reservations and unauthorized cancellation of member users waiting for the charging order, useless free time of the quick charger 22 of the charging stand 2 is suppressed, and the quick charger 22 of the charging stand 2 is more efficient. Can be operated automatically.

  In addition, when a charge reservation is canceled, the reservation time of other charge waiting member users who wish to advance the reservation time is sequentially increased. Generation | occurrence | production of the state which is not operating can be suppressed. Even if a charge reservation is canceled, if the member user waiting for the next charge of this charge reservation does not want to advance the reservation time, the charge reservation of the required charge time that falls within the free time generated by the cancellation of the charge reservation Since charging reservations for waiting-for-charge member users are advanced, it is possible to suppress the occurrence of idle time in the quick charger of the charging station. For this reason, the quick charger of the charging station can be operated more efficiently.

  Therefore, even in the stage of promoting the popularization of electric vehicles that are dotted with small charging stations, the usage efficiency of a small number of charging devices in each charging station can be improved, and the burden on drivers who use charging stations can be reduced. Can do.

  In addition, this invention is not limited to said embodiment, Many deformation | transformation are possible within the range of the summary.

  For example, among the charging reservation support services described above, the reservation cancellation service and the active charging station reservation service are provided not only through the operation panel 22 of each charging station 2 but also through the wireless communication information terminals 6 and 51 of the member users. Also good. In this case, after user authentication, the server processing unit 11 of the management server 1 returns a top menu in which the reservation cancel button and the active charging stand charging reservation button are arranged as menu item buttons to the wireless communication information terminals 6 and 51. If the reservation cancel button is selected, a reservation confirmation request is transmitted from the wireless communication information terminals 6 and 51. In response to this, the management server 1 provides a reservation cancellation service similar to that described above to the wireless communication information terminals 6 and 6. 51. On the other hand, if the operating charging station charging reservation button is selected, an operating station search menu acquisition request is transmitted from the wireless communication information terminals 6 and 51. In response to this, the management server 1 sets the operating station search menu to the wireless communication information. A reply to the terminals 6 and 51 is provided to provide the wireless communication information terminals 6 and 51 with an operation charging station reservation service similar to that described above. However, in the service charging station reservation service in this case, the operation charge station reservation status confirmation page displayed on the wireless communication information terminals 6 and 51 further includes an input field of a desired area (such as a municipality) The application unit 12 of the management server 1 searches for an operating charging station in the desired area. In this case, the desired search distance range entered on the active charging station reservation status confirmation page (distance priority) is searched from the position of the wireless communication information terminals 6 and 51 (position measurable by existing technology such as GPS). It will be the maximum distance to the desired charging station.

  In the above embodiment, the electric vehicle is a target for charging. However, the electric vehicle charging system according to the present embodiment can be applied to any electric vehicle as long as the electric vehicle is driven by the power of the mounted battery. Applicable.
