In the present embodiment, “1 (auto extend)” is basically set in the auto extension flag area, and “0 (do not extend)” is set only when the transaction management side specifically requests. Is done.

  The transaction management device 100 configured as described above manages the location and state of all the secondary batteries that can be distributed or can be distributed. That is, when a secondary battery is newly produced by the transaction management device 100, information on the secondary battery is newly registered, and a transaction is performed with the user, which is sold by the user. Are registered as pooled on the management side, and those purchased by the user are registered as being attached to the application device owned by the user. Furthermore, the state of the secondary battery is constantly monitored by the transaction management device 100 linked to the registration information, and transactions are performed and distributed in units of battery packs according to the state.

  Hereinafter, details of the processing performed in the transaction management apparatus 100 will be described with reference to the flowcharts shown in FIGS.

  First, a new battery pack registration process will be described with reference to the flowchart shown in FIG.

  The table creation / change unit 142 of the transaction management device 100 is always waiting for a new application for battery pack registration (S10). The application for new registration of the battery pack is basically made by the vendor 6. When the table creation / change unit 142 receives a new battery pack registration application from the computer 16e of the vendor 6 through the communication control unit 161, the table creation / change unit 142 first determines the pack ID of the battery pack (S11).

  Here, there are two forms of this new registration application. The first form is an application relating to a battery pack already attached to the application device. In this case, in this new registration application, in addition to the effect of new registration, the battery pack owner ID (the ID of the seller 6), the type of the application device in which the battery pack is mounted, the communication address of the owner ( The communication address of the seller, etc.), the battery type of the secondary battery incorporated in the battery pack, the number of secondary batteries incorporated in the battery pack, and all secondary batteries incorporated in the battery pack The serial number is also accepted. The second form is an application relating to a battery pack in which it is not determined which application device is mounted. In this case, in this new registration application, except for the type of application device to which the battery pack is mounted, as in the former case, the new registration, the battery pack owner ID (ID of the seller etc. 6), The communication address of the owner (communication address of the seller, etc.), the battery type of the secondary battery incorporated in the battery pack, the number of secondary batteries incorporated in the battery pack, and the battery pack. The serial numbers of all the secondary batteries are received, and the selling price of the battery pack is also received.

  Therefore, the table creation / change unit 142 determines whether or not the type of the application device has been received when the application for new registration is received (S12).

  If the table creation / change unit 142 determines in step 12 that the application device type has not been accepted at the time of application for new registration, that is, the application is in the above-described second form, In order to pool the battery as a secondary battery that can be traded on the transaction management side, the battery performs the following steps 13a to 15.

  The table creation / change unit 142 first creates a new record in the pack management table 111 (FIG. 4) and stores information related to the battery pack (S13a).

  That is, the table creation / change unit 142 creates a new record in the pack management table 111, and sets the owner ID and the communication address of the owner received when applying for a new battery pack registration. 111 (FIG. 4) is stored in the owner ID area 111a and the owner communication address area 111e in the new record created. Further, the pack ID determined in step 11 is stored in the pack ID area 111b. This completes data storage in the new record created in the pack management table 111. In the case of the application in the second form, the application type and the pack communication address are not received at the time of application reception, so the application type area 111c and the pack communication address area 111d are included in the new record of the pack management table 111. It is blank.

  When the information storage in the pack management table 111 is completed (S13a), the table creation / change unit 142 causes the sales information creation unit 152 to create normal purchase information for the battery pack (S14). It is stored in 118 (S15).

  In this way, the normal purchase information of the battery pack is created and stored in the normal purchase information table 118. This is because the battery pack can be sold by the transaction manager, in other words, the purchase target of the general user. It is for managing as a battery pack.

  In step 14, the table creating / changing unit 142 receives the battery type of the secondary battery incorporated in the battery pack, the number of secondary batteries incorporated in the battery pack, and the battery pack received in step 10. The manufacturing numbers of all the incorporated secondary batteries, the selling price of the battery pack, and the pack ID determined in step 11 are passed to the buying and selling information creating unit 152.

  The trading information creation unit 152 creates a new record in the normal buying information table 118 (FIG. 11), and stores the battery type area 118f, the constituent battery number area 118g, the buying price area 118i, and the manufacturing number area 118p in the record. The battery type of the secondary battery incorporated in the battery pack, the number of secondary batteries incorporated in the battery pack, the selling price of the battery pack, and the battery pack passed from the table creation / change unit 142 Stores the serial numbers of all installed secondary batteries. Further, the buying / selling information creating unit 152 stores the pack ID determined in step 11 in the target pack ID area 118d in the new record of the normal buying information table 118, and “in the minimum value area 118l in the new record”. “100”, “100” is stored in the median value area 118m, and “−” is stored in the variance value area 118n.

  The price stored in the buying price area 118i of the normal buying information table 118 is the buying / selling price of a new battery pack received by the table creating / changing unit 142 in step 10. The values stored in the minimum value area 118l and the median value area 118m of the normal purchase information table 118 are both “100”. This is because the battery pack is new, all the secondary batteries incorporated in the battery pack are also new, and these performance values are all the performance value “100” with respect to the new product.

  When the buying and selling information creation unit 152 finishes storing the purchase information of the battery pack (S15), the table creation / change unit 142 passes the pack ID determined in step 11 to the communication control unit 161, and the pack ID is received. It is made to transmit to the computer 16e of the sales agency etc. 6 of an application origin (S16). This completes the new battery pack registration process.

  If the table creation / change unit 142 determines in step 12 that the type of application device has been received when the application for new registration is received, that is, the application is in the first form described above, the pack management table 111 (FIG. 4). ), A new record is created and information relating to the battery pack is stored (S13b).

  The table creation / change unit 142 creates a new record in the pack management table 111 (FIG. 4), and receives the owner ID, the type of application device, and the communication address of the owner received at the time of new battery pack registration application. Are stored in the owner ID area 111a, the application type area 111b, and the owner communication address area 111e in the new record created in the pack management table 111, respectively. Further, the pack ID determined in step 11 is stored in the pack ID area 111b. This completes data storage in the new record created in the pack management table 111.

  When the table creation / change unit 142 completes the creation of various tables (S13b), it passes the pack ID determined in step 11 to the communication control unit 161, and passes this pack ID to the computer 16e of the seller 6 of the application source. Transmit (S16). This completes the new battery pack registration process.

  By the way, in this embodiment, the new registration application for the battery pack is an application in the first form, that is, the battery pack is already mounted on the application device, or has already been determined to be mounted on a specific application device. In the case application, the process of creating the battery pack purchase information (S14, 15) or the like is not performed as in the case of the application for the new registration of the battery pack in the second form. This is because the transaction management apparatus 100 according to the present embodiment is involved in buying and selling of the battery pack alone, and is not directly involved in buying and selling of the application apparatus on which the battery pack is mounted. However, when there is a purchase / sell of an application apparatus in which the battery pack is mounted, in this embodiment, as will be described later with reference to FIG.

  In the above description, when the table creation / change unit 142 determines that the application device type is not received when the new registration application is received, that is, the application in the second form described above, the sales information creation unit 152. However, the normal buying information of the battery pack is created and the normal buying information is stored in the normal buying information table. However, the buying and selling information creating unit 152 also creates the auction buying information of the battery pack, and this auction. The purchase information may be stored in the auction purchase information table.

  Next, processing when the owner of the battery pack changes with the application apparatus will be described according to the flowchart shown in FIG. Specifically, when a vendor 6 that sells an application device with a battery pack attached sells the application device to a general user, or a second-hand store that resells a used application device with a battery pack attached. The following processing is executed when the application device is sold to a general user. For this reason, the owner's change application is made by a vendor that sells the application device with the battery pack attached, or a second-hand store that resells a used application device with the battery pack attached.

  The table creation / change unit 142 of the transaction management apparatus 100 is always waiting for a change application of the owner of the battery pack (S20).

  In this change application, in addition to the change of the owner, the owner ID of the old owner, the owner ID of the new owner, the pack ID, the type of application device in which the battery pack is incorporated, the state of this battery pack New communication address of the sender of information (new pack communication address), communication information of the new owner, information on whether the communication address of the destination of trading information is the new pack communication address or the communication address of the new owner, Accept.

  The table creation / change unit 142 first extracts a record of the old owner ID from the pack management table 111 (FIG. 4) using the old owner ID received at the time of the change application as a search key (S21).

  Next, the table creation / change unit 142 determines whether the pack ID and the application device type in the record of the old owner ID match the pack ID and the application device type received at the time of the change application. (S22). If the table creation / change unit 142 determines that they do not match, the communication control unit 161 sends a request to the application source to confirm the change application data (S23), and ends the series of processes.

  If the table creation / change unit 142 determines that they match, the owner ID area 111a, the pack communication address area 111d, the owner communication address area 111e in the record of the old owner ID of the pack management table 111, the buying and selling, The new pack communication address is the new owner ID, new pack communication address, new owner communication address, and sales information communication address received at the time of the change application. Or the communication address of the new owner (S24), and the series of processes is terminated.

  Next, the operation when receiving a notification of the completion of disposal of the secondary battery from the recycling factory 7 will be described according to the flowchart shown in FIG.

  The computer 16f of the recycling factory 7 regularly monitors the state area 123d of the pool battery information table 123 shown in FIG. 14, and the state area 123d in any record of the pool battery information table 123 is “2 (discarded). ")" Is displayed on the display device of the computer 16f that the secondary battery having the serial number in the record is requested to be discarded.

  Here, the computer 16f of the recycling factory 7 periodically monitors the state area 123d of the pool battery information table 123 so as to grasp the disposal request for the secondary battery. However, when the status area 123d in any record of the pool battery information table 123 is set to “2 (discard)”, the transaction management apparatus 100 itself may transmit this information to the computer 16f of the recycling factory 7. Good.

  The worker of the recycling factory 7 sees this display, picks up the secondary battery of the corresponding production number from the transaction management side, disassembles the secondary battery, and takes out various metal materials and the like from the secondary battery. When the work on the secondary battery is completed, the worker or the like notifies the transaction management apparatus 100 of the completion of the disposal of the secondary battery using the computer 16f of the recycling factory 7. At this time, along with the fact that the disposal has been completed, the serial number of the secondary battery that has been disposed of is also notified.

  When the table creation / change unit 142 of the transaction management apparatus 100 accepts the completion of disposal of the secondary battery and the serial number of the secondary battery after disposal from the computer 16f of the recycling factory 7 ("YES" in S30). In the pool battery information table 123 shown in FIG. 14, it is determined whether or not “2 (discard)” is stored in the status area 123 related to the received manufacturing number.

  When the table creation / change unit 142 determines that “2 (discard)” is not stored in the status area 123 related to the received manufacturing number in the pool battery information table 123, the communication control unit 161 notifies the discard completion. A message indicating that the notification data is desired to be confirmed is transmitted to the source (S32), and the series of processes is terminated.

  When the table creation / change unit 142 determines that “2 (discard)” is stored in the status area 123 related to the received manufacturing number in the pool battery information table 123, Delete the record of the serial number. Next, the table creating / changing unit 142 refers to the pack condition information table 112 (FIG. 5) including the manufacturing number, and acquires the pack ID of the battery pack including the secondary battery with the manufacturing number. This pack condition information table is deleted. Further, the table creating / changing unit 142 deletes the record including the previously acquired pack ID from the pack management table 111 (FIG. 4) (S33), and ends the series of processes.

  By the way, in step 33, the pack condition information table 112 that includes the manufacturing number of the secondary battery that has been discarded is deleted, and the record that includes the pack ID of the battery pack that includes the secondary battery is deleted from the pack management table 111. ing. This is because, when “2 (Discard)” is set for the secondary battery, no user owns the battery pack containing the secondary battery, and information on the battery pack is displayed. This is because it will not be used in the future. However, if it is necessary to collect information regarding the battery pack including the discarded secondary battery for some reason, for example, the table to be deleted may be copied to another storage device.

  Next, according to the flowcharts shown in FIG. 20 and FIG. When the application device is operating and the secondary battery of the battery pack attached to the application device is charging / discharging, the transaction management device 100 communicates with the application device side and is attached to the application device. Monitor the status of the battery pack. Furthermore, the transaction management device 100 updates selling information including the purchase price of the secondary battery of the battery pack attached to the application device, based on the state monitoring result of the implemented battery pack.

  When the application device in which the battery pack is mounted operates and the secondary battery in the battery pack starts charging and discharging, the CMU 13 in the battery pack 11a (11b, 11c, 11d) shown in FIG. Various state values such as the inter-terminal voltage, the terminal current, and the integrated value of the terminal current of one or more secondary batteries 12 are acquired and sent to the BMU 14. The BMU 14 is periodically incorporated into the transaction management apparatus 100 from the communicable device 17 (17, 16c, 17d) connected to the battery pack 11a (11b, 11c, 11d). The state values of all secondary batteries are transmitted.

  The cycle in which the BMU 14 transmits the state value of the secondary battery to the transaction management apparatus 100 via a communicable device is, for example, 10 seconds. Further, the data that the BMU 14 transmits to the transaction management apparatus 100 via a communicable device includes the pack ID of the battery pack, the serial numbers of all the secondary batteries incorporated in the battery pack, and the serial numbers. Is the state value associated with.

  When the performance value acquisition unit 143 of the transaction management apparatus 100 receives the state values of all the secondary batteries incorporated in the battery pack together with the pack ID of any battery pack via the communication control unit 161 ( In S40, “1” is added to the value of the status value reception counter relating to the pack ID (S41).

  Subsequently, the performance value acquisition unit 143 calculates the performance value of each secondary battery based on the received status value of each secondary battery, and stores the received pack ID in the pack status information table 113 (FIG. 6). This value is stored (S42). At this time, the performance value acquisition unit 143 provides a new record in each of the time region 113e, the performance value region 113c, and the change coefficient region 113d for each serial number in the pack state information table 113, and the time in the new record The time when the state value is received is stored in the area 113e, and the calculated performance value is stored in the performance value area 113c in the new record.

  Here, a method for calculating the performance value of the secondary battery will be briefly described.

  As the temperature of the secondary battery increases, the performance value representing the performance of the battery, which changes depending on use, is promoted to decrease. In other words, the degree of deterioration of the secondary battery is promoted. Since the temperature of the secondary battery has a correlation with the charge / discharge current of the secondary battery, the performance value can be obtained by using the integrated value of the charge / discharge current. Further, the integrated value of the charge / discharge current can be obtained by providing an ammeter for measuring the terminal current of the secondary battery in the battery pack and integrating the current value from the ammeter with the CMU or BMU. .

  Therefore, a function that defines the relationship between the integrated value of the charge / discharge current and the performance value is prepared in advance, and the integrated value of the charge / discharge current is acquired as the state value of the secondary battery. Is input to the function, the performance value of the secondary battery can be obtained.

  The above method is the method disclosed in Japanese Patent Application Laid-Open No. 2006-197765. Further, as the state value of the secondary battery, the integrated value of the start time of the secondary battery or the start of the secondary battery is used. The integrated value of the number of times may be acquired, and the performance value of the secondary battery may be obtained by appropriately weighting each of the integrated value of the charge / discharge current, the integrated value of the starting time, and the integrated value of the starting number of times. .

  Further, when the deterioration of the secondary battery progresses, the phase difference of the voltage waveform with respect to the current waveform when a specific charging / discharging current is applied to the secondary battery increases, and the voltage fluctuation width with respect to the current fluctuation width also increases. . Therefore, a function that defines the relationship between the phase difference of the voltage waveform with respect to the current waveform, the voltage fluctuation width with respect to the current fluctuation width, and the performance value is prepared in advance and specified as the secondary battery state value. The performance value of the secondary battery can be obtained by acquiring the above phase difference and voltage fluctuation width when applying the charging / discharging current and inputting these values into the function.

  As described above, there are various methods for obtaining the performance value of the secondary battery, and in the present invention, the performance value of the secondary battery may be obtained by any method.

  In the present embodiment, the performance value acquisition unit 143 receives the state value of the secondary battery from the battery pack side, and acquires the performance value of the secondary battery based on the state value. The CMU or BMU may obtain the performance value of the secondary battery based on the state value of the secondary battery, and the performance value acquisition unit 143 may acquire the performance value from the battery pack side.

  When the performance value acquisition unit 143 calculates the performance value of each secondary battery (S42), the change tendency calculation unit 146 calculates the amount of change in performance value per unit period for the performance value of each secondary battery. The change coefficient of the performance value is stored in the change coefficient area 113d in the newly created record of the pack state information table 113 (S43).

  As a method of obtaining the coefficient of change of the performance value, for example, there is a method of acquiring a performance value before a specific period from the time when the performance value is acquired, and dividing the difference between the two performance values by the specific period. In addition, there is a method of linearly approximating the performance value during a specific period by the mean square method and using the slope of this straight line as a change coefficient.

  When the change coefficient of the performance value of each secondary battery is calculated (S43), the performance value acquisition unit 143 determines whether any of the state values of each secondary battery received in step 40 is abnormal. Is determined based on a predetermined threshold (S44).

  When the performance value acquisition unit 143 determines that any of the state values of any of the secondary batteries is abnormal among the state values of each of the secondary batteries, the performance value acquisition unit 143 receives the state value of the state value via the communication control unit 161. A battery pack abnormality is notified to the transmission source (S45), and a series of processing ends.

  Here, the communication address of the transmission source of the state value is a communication address stored in the pack communication address area 111d of the pack management table 111. When the device of this communication address receives a battery pack abnormality from the transaction management device 100, the battery pack abnormality is displayed on the display connected to this device. Specifically, for example, when the communication address stored in the pack communication address area 111d is the communication address of the wireless communication device 17 shown in FIG. The fact that the battery pack 11a attached to the automobile 10a is abnormal is received. In response to the notification that the abnormality is present, the ECU 20 displays a battery pack abnormality on the display of the monitor 21 connected to the ECU 20.

  Since the secondary battery abnormality can be recognized by the BMU or CMU of the battery pack in which the secondary battery is incorporated, the notification of the battery pack abnormality is performed from the viewpoint of double safety.

  If the performance value acquisition unit 143 determines in step 44 that none of the state values of any of the secondary batteries is abnormal, the performance value of any of the secondary batteries is attached to the secondary battery as a battery pack. It is determined whether or not the performance value exceeds the allowable performance value allowed as the performance value in the application device (S46). At this time, the performance value acquisition unit 143 acquires the allowable performance value from the allowable performance value area 112e of the pack condition information table 112 (FIG. 5) of the battery pack.

  If the performance value acquisition unit 143 determines that the performance value of any of the secondary batteries is not equal to or greater than the allowable performance value, the battery pack is connected to the state value by the performance control via the communication control unit 161 to the transmission source. The device is notified that it is at the use limit (S47), and the process proceeds to step 48. If the performance value acquisition unit 143 determines that the performance value of any secondary battery is equal to or greater than the allowable performance value, the process immediately proceeds to step 48.

  In step 48, the performance value acquisition unit 143 determines whether or not the value of the state value reception counter is a predetermined value “C”. Here, the value of “C” is, for example, the number of times the status value of the pack ID is received during one week.

  If the value of the state value reception counter has not reached the predetermined value “C”, the series of processes is terminated. When the value of the state value reception counter is a predetermined value “C”, the selling price calculation unit 145 calculates the selling price of the battery pack, and the pack rebuilding unit 151 A new battery pack is reconstructed using at least one secondary battery among a plurality of secondary batteries incorporated in the battery pack (FIG. 21, S50). Here, the calculated selling price is the normal selling price and the auction selling price, and the new battery pack to be reconstructed is for the normal trading and the auction trading. These information is stored in the selling information tables 117 and 121. Stored. The calculation of the selling price and the method for reconstructing a new battery pack will be described in detail later.

  When the selling price calculation process and the pack restructuring process (S50) are finished, the future selling price prediction unit 148 stores the normal selling price and the auction selling price calculated in step 50 and the pack status information table 113 of the battery pack. A future normal selling price and a future auction selling price are calculated using the variation coefficient stored in the variation coefficient area 113d (S51). A method for calculating the future normal selling price and the future auction selling price will be described in detail later.

  When the future selling price calculation process (S51) ends, the buying and selling information creation unit 152 creates display normal selling information, display auction selling information, display normal buying information, and display auction buying information (S52). .

  At this time, the buying / selling information creating unit 152, for the battery pack, the past normal and auction selling prices, the normal and auction selling prices determined in step 50, and the normal prices determined in step 51. And the future selling price for the auction, as shown in the selling information areas 35a and 35b in FIG. 32 and FIG. Display selling information including graphs 36a and 36b indicating fluctuations in the number of items is created.

  Further, the buying / selling information creating unit 152 recognizes the pack condition (battery type, number of constituent batteries, allowable performance value) of the battery pack from the pack condition information table 112 (FIG. 5) of the battery pack, and the normal purchase information table. All records satisfying the pack condition are extracted from 118 (FIG. 11), and the normal buying information for display for the owner of the battery pack is created using the data in the record. This normal buying information for display includes a pack ID, various statistical values of performance values, and a normal buying price in the extracted record, as shown in the normal buying information area 40a of FIG.

  Further, the sales information creation unit 152 extracts all records that satisfy the battery pack condition from the auction purchase information table 122 (FIG. 13), and uses the data in this record to acquire the owner of the battery pack. Auction buying information for display is created. In this display auction buying information, as shown in the auction buying information area 40b of FIG. 33, the pack ID in the extracted record, various statistical values of performance values, auction buying reference, as well as the normal buying information. The price and the bidding period of the battery pack with the pack ID are included.

  If there is a bid information table 125 including the pack ID in the previously extracted record among the plurality of bid information tables 125 (FIG. 16), the sales / trading information creation unit 152 has a bid start area 125 c of the bid information table 125. The bid start date and time stored in, and the bid end date and time stored in the bid end area 125d are acquired, and these date and time are set as the bid period of the battery pack of the pack ID.

  When the buying and selling information creation process (S52) by the buying and selling information creation unit 152 ends, the bid management unit 154 includes a new battery in which no bid period is set in the display auction buying information created by the buying and selling information creation unit 152. It is determined whether pack information is included (S53).

  When the bid management unit 154 determines that information on a new battery pack for which no bid period is set is included, the bid management unit 154 creates a bid information table 125 (FIG. 16) regarding this battery pack (S54).

  The bid management unit 154 stores the pack ID of the new battery pack in the target pack ID area 125a of the bid information table 125, stores “1 (automatic extension)” in the automatic extension flag area 125b, and starts the bid start area. The date and time when the display auction purchase information is scheduled to be transmitted to the user is stored in 125c, and the date and time after a predetermined period (for example, one week later) is stored in the bid end area 125d. Here, since the date and time for transmitting the display auction purchase information related to the new battery pack to the user is stored in the bid start area 125c, the start of bidding for the new battery pack is performed by using the display auction purchase information. It is time to send to the user for the first time.

  When the bid management unit 154 creates the bid information table 125 related to the new battery pack (S54), the bid start date and time and the bid end date and time are added to the information related to the new battery pack in the previously created display auction purchase information. Then (S55), the process proceeds to step 56.

  If the bid management unit 154 determines in step 53 that information on a new battery pack for which a bid period is not set is not included, the process immediately proceeds to step 56.

  In step 56, the buying and selling information providing unit 153 passes the display buying and selling information created in steps 52 and 55 to the communication control unit 161, and causes the display buying and selling information to be transmitted to the transmission source or the like of the state value of the battery pack. .

  Here, the transmission source or the like of the state value of the battery pack means that “owner” is stored in the buying and selling information transmission destination area 111f in the record in which the pack ID of the battery pack is stored in the pack management table 111. In the case where the device has the owner communication address stored in the owner communication address area 111e in the record, and “pack” is stored in the trading information transmission destination area 111f, The device of the pack communication address stored in the pack communication address area 111e in the record.

  For example, in FIG. 1, the transmission source of the state value related to the battery pack 11a attached to the automobile 1a is the wireless communication device 17. If, in the pack management table 111, “pack” is stored in the buying / selling information transmission destination area 111f in the record relating to the battery pack 11a, it is stored in the pack communication address area 111d in the record. The trade information for display of the battery pack 11a is transmitted to the wireless device 17 having the communication address. This display trading information is displayed on the display of the monitor 21 connected to the ECU 20 by the ECU 20 shown in FIG.

  The transmission source of the state value related to the battery pack 11b attached to the automobile 1b is the wireless communication device 17. If, in the pack management table 111, “owner” is stored in the sales information transmission destination area 111f in the record relating to the battery pack 11b, the record is stored in the owner communication address area 111e in the record. The trading information for display of the battery pack 11b is transmitted to the computer 16b having the communication address. This trade information for display is displayed on the display of the computer 16b.

  When the display trading information is transmitted, the performance value acquisition unit 143 clears the value of the state value reception counter and ends the series of processes.

  By the way, unless the battery pack becomes abnormal, the selling price of the battery pack basically does not fluctuate greatly within a short period (for example, 1 to 2 weeks). Moreover, the calculation of the selling price of the battery pack is a load on the transaction management apparatus 100. Therefore, in this embodiment, every time a status value is sent (for example, every 10 seconds), the value of the status value reception counter is counted up, and this counter value is, for example, a counter value (C) for one week. (S48: “YES”), the selling price of the battery pack is calculated.

  Next, the contents of the sales information display screen will be described with reference to FIGS. 32 and 33. As described above, this display screen is a screen displayed on the display on the general user side.

  As shown in FIG. 32, the display screen 30a for normal trading information includes a display content area 31a in which the name of the display content is shown, and pack conditions for the battery pack owned by the user who is the source of the state value. A pack condition area 34 shown, a normal sale information area 35a showing normal sale information, a normal buy information area 40a showing passing / buying information, and an execution button 50 are displayed.

  In the display content area 31a, both “normal sales information” 32a and “auction sales information” 33a are displayed. On the normal sales information display screen 30a, “normal sales information” 32a is clearly displayed. "Information" 33a is displayed indistinctly.

  The pack condition area 34 displays the battery type of the secondary battery incorporated in the battery pack owned by the user, the number of constituent batteries of the battery pack, and the allowable performance value of the secondary battery as the pack condition. The

  In the normal sale information area 35a, a graph 36a indicating fluctuations in the normal sale price from the past to the future, and a sale button 39a for displaying an intention to sell the battery pack owned by the user to the transaction management side are displayed. Is done.

  The graph 36a is a graph in which the horizontal axis represents time and the vertical axis represents the normal selling price. The horizontal axis of this graph shows the current position, and the vertical axis shows the current normal selling price.

  Here, the fluctuation tendency of the selling price of the battery pack will be described. The buying and selling price of the battery pack does not decrease linearly with the passage of time, and the tendency of the price to decrease with the passage of time tends to increase every time a specific time point elapses.

  If the battery type A secondary battery is mounted on an automobile, the allowable performance value is 80, and if it is mounted on a wind turbine power storage device, the allowable performance value is 50, and is used in a general household power storage device. In the case of mounting, it is assumed that the allowable value is 20. When the performance value of the battery type A secondary battery falls below the allowable value 80 for automobiles, it becomes unsuitable for installation in automobiles. Therefore, users who own automobiles try to purchase secondary batteries with performance values lower than 80. I do not think. For this reason, since the number of consumers decreases rapidly around the performance value 80, the tendency of the secondary battery price to decrease changes. Similarly, even if the permissible performance value 50 for the power storage device of the windmill is around, or the permissible performance value 20 for the power storage device of a general household is around, the decreasing tendency of the price of the secondary battery changes.

  For this reason, when the performance value reaches 80, the performance value reaches 50, and the performance value reaches 20, the price of the secondary battery changes with time.

  The graph 36a reflects the price fluctuation trend described above. If the normal selling price of the battery pack is a graph that sharply decreases in the near future, the user who sees this graph can recognize that the current time is the selling time of the battery pack. For this reason, in the present embodiment, a graph 36a indicating fluctuations in the normal selling price from the past to the present and from the present to the future is displayed.

  In the normal purchase information area 40a, a table 41a relating to battery packs that satisfy the pack conditions of the battery packs owned by the user and can be purchased by the user from the transaction management side is displayed.

  In this table 41a, a pack ID area 42a that stores the pack ID of the battery pack that satisfies the pack conditions of the battery pack owned by the user and that can be purchased from the transaction management side by the user, The minimum value area 43a in which the minimum performance value is stored among the performance values of the plurality of secondary batteries incorporated in the battery pack, and the median value of the performance values of the plurality of secondary batteries are stored. A median value area 44a, a variance value area 45a in which the variance values of the performance values of the plurality of secondary batteries are stored, a price area 46a in which the normal purchase price of the battery pack is stored, and the battery pack And a check box area 47a in which a check box for displaying an intention to buy is stored.

  When the user looks at the display screen 30a for the normal buying and selling information and decides to sell the battery bag owned by the user, the user clicks the sell button 39a. When the sell button 39a is clicked, for example, “Please click the check box of the battery pack that you want to purchase” is displayed on the display screen 30a. Therefore, the user clicks one of the check boxes in the normal purchase information area 40a. When the check box is clicked, for example, in the display screen 40a, for example, “If you sell a battery pack you own and want to buy a specified battery pack, please press the execution button.” Is displayed. Therefore, when the user clicks the execute button 50, the battery pack ID of the battery pack that he / she owns, and the fact that he / she sells this battery pack, and the purchase / designated pack ID and the fact that he / she buys the battery pack of the pack ID It is transmitted to the transaction management apparatus 100.

  Further, when the user looks at the display screen 30a for the normal buying / selling information and determines that one of the battery packs displayed in the normal buying information area 40a is to be purchased, the user clicks a check box for the battery pack. When the check box is clicked, on the display screen 30a, for example, “You own battery pack will be sold. When you sell your battery pack and want to buy the specified battery pack. Please press the execution button. "Is displayed. Therefore, when the user clicks the execution button 50, as in the case described above, the pack ID of the battery pack that he / she owns, the fact that the battery pack is to be sold, the pack ID which he / she specified to purchase, and the battery of the pack ID The fact that a pack is to be purchased is transmitted to the transaction management apparatus 100.

  By the way, when selling a battery pack owned by a user, it becomes necessary to purchase a new battery pack. When a user purchases a battery pack, the battery pack owned by the user is sure to be purchased. Is no longer needed. For this reason, in this embodiment, selling and buying of the battery pack by the user are linked.

  When the user wants to view the auction sales information, the user clicks “auction sales information” 32a in the display content area 31a of the normal sales information display screen 30a. As a result of this click, a display screen 30b for auction buying and selling information is displayed on the display on the user side as shown in FIG.

  In the auction sale information area 35b, a graph 36b showing a change in the auction sale price from the past to the future, and a sale button 39b for displaying an intention to sell the battery pack owned by the user to the transaction management side are displayed. Is done.

  The graph 36b is a graph in which the horizontal axis represents time and the vertical axis represents the auction selling price. The horizontal axis of this graph shows the current position, and the vertical axis shows the current auction selling price. As will be described later, the future auction selling price is obtained from the change coefficient of the performance value of the secondary battery in the pack at the present time and a plurality of actual auction prices corresponding to the future performance value estimated from the change coefficient. ing. Therefore, in this embodiment, in consideration of user convenience, an average value of a plurality of actual auction prices corresponding to future performance values is displayed as a future auction average selling price 37a, and a plurality of actual auction prices are displayed. The minimum value is displayed as the future auction minimum selling price 37b, and the maximum value among the plurality of actual auction prices is displayed as the future auction maximum selling price 37c.

  In the auction purchase information area 40b, a table 41b relating to a battery pack that satisfies the pack conditions of the battery pack owned by the user and can be purchased from the transaction management side by the auction, and purchases the battery pack at the auction. A bid price input area 49 for inputting a bid price at the time of performing is displayed.

  The table 41b includes a pack ID area 42b in which pack IDs of battery packs that satisfy the pack conditions of the battery packs owned by the user and that can be purchased by the user from the transaction management side through an auction are stored. The minimum value area 43b in which the minimum performance value is stored among the performance values of the plurality of secondary batteries incorporated in the battery pack, and the median value of the performance values of the plurality of secondary batteries are stored. A median value area 44b, a variance value area 45b in which the variance values of the performance values of the plurality of secondary batteries are stored, a price area 46b in which the auction purchase reference price of the battery pack is stored, A check box area 47b in which a check box for indicating the intention to buy the battery pack is stored, and a bid period of the battery pack is stored. And bidding period region 48b is provided that.

  When the user looks at the display screen 30b of the auction sales / purchase information and decides to sell the battery bag owned by the user, the user clicks the sell button 39b. When the sell button 39b is clicked, on the display screen 30b, for example, "Please click the check box of the battery pack that you want to purchase at the auction and enter the bid price of this battery pack." Is displayed. Therefore, the user clicks on any check box in the auction purchase information area 40b and inputs a bid price. When the check box is clicked and the bid price is entered, for example, in this display screen 40b, for example, “If you sell your battery pack and want to buy the specified battery pack at the auction, execute Please press the button. "Is displayed. Therefore, when the user clicks the execution button 50, the pack ID of the battery pack that he / she owns, the fact that the battery pack is sold for the auction, the pack ID specified for purchase, the bid price, and the pack ID To buy the battery pack at the auction is transmitted to the transaction management apparatus 100.

  Further, when the user looks at the display screen 30b of the auction buying / selling information and determines that one of the battery packs displayed in the auction buying information area 40b is to be purchased, the user clicks a check box for the battery pack. Enter the bid price for this battery pack. When the check box is clicked and the bid price of this battery pack is entered, for example, in this display screen 30b, “You will sell your battery pack.

" Therefore, when the user clicks the execution button 50, as in the case described above, the pack ID of the battery pack that he / she owns, the fact that this battery pack will be sold for auction, and the pack ID specified for purchase, the bid The price and the fact that the battery pack having the pack ID is purchased at an auction are transmitted to the transaction management apparatus 100.

  By the way, there is a case where there is no battery pack subject to auction satisfying the pack condition of the battery pack owned by the user. In such a case, the auction sales information is displayed on the auction sales information display screen 30b, but the auction purchase information is not displayed. In this case, when the user clicks the sale button 39b in the auction sale information area 35b, for example, in the display screen 30b, “Please check the normal sale information and click the check box of the battery pack you want to purchase. Is displayed. Therefore, the user first clicks “normal trading information” 32b in the display screen 30b. By this click, a display screen 30a (FIG. 32) for normal trading information is displayed on the display. Then, the user clicks one of the check boxes in the normal purchase information area 40a on the display screen 30a. When the check box is clicked, for example, in this display screen 40a, for example, “If you want to sell your battery pack as an auction target and buy the specified battery pack, please press the execution button. Is displayed. Therefore, when the user clicks the execute button 50, the pack ID of the battery pack that he / she owns and the fact that the battery pack is sold as an auction object, and the purchase ID and the battery pack of the pack ID are purchased. Is transmitted to the transaction management apparatus 100.

  Next, according to the flowcharts shown in FIGS. 22 to 25, the details of the normal selling price calculation and the pack rebuilding process in step 50 of FIG. 20 will be described.

The pack restructuring unit 151 selects the secondary battery incorporated in the battery pack having the pack ID received in step 40 of FIG. 20 (hereinafter referred to as the target pack) from the pack condition ranking table 116 shown in FIG. The pack condition ranking table 116 that matches the battery type is selected. Then, an unselected and highest pack condition is selected from the pack condition ranking table 116 (S501). In this case, since it is the selection of the first pack condition, from the pack condition ranking table 116 shown in FIG. 9, the pack condition of ranking “1”, that is, the allowable performance value Sp “80”, the number of constituent batteries N ₀ “100”. Select.

  Next, the pack rebuilding unit 151 extracts an unextracted Max performance value from the latest performance values of each secondary battery in the pack state information table 113 (FIG. 6) regarding the target pack (S502). Assume that the performance value extracted here is “84”. In addition, in the extraction of the performance value in each of the following steps including the step 502, the serial number associated with the performance value is also included because it is necessary to recognize the performance value of which secondary battery. Extract.

  Next, the pack restructuring unit 151 determines whether or not the Max performance value extracted in Step 502 is larger than the allowable performance value Sp extracted in Step 502 (S503). If the Max performance value is larger, the process proceeds to Step 504, and if the Max performance value is not larger, the process proceeds to Step 531. In this case, the Max performance value is “84”, the allowable performance value Sp is “80”, and the Max performance value is larger, so the process proceeds to Step 504.

  When the processing proceeds to step 531, the pack restructuring unit 151 treats the Max performance value extracted at step 502 as unextracted. Then, the pack restructuring unit 151 determines whether or not all pack conditions have been selected from the pack condition ranking table 116 shown in FIG. 9 in step 535 (FIG. 25). If all the pack conditions have not been selected, the process returns to step 501 to select the unselected and highest pack condition from the pack condition ranking table 116 again. In this case, since the pack condition of ranking “1” is selected from the pack condition ranking table 116, the pack condition of ranking “2” is selected. Next, in step 502, the pack rebuilding unit 151 extracts an unextracted Max performance value from among the latest performance values of each secondary battery in the pack state information table 113. In this case, since the Max performance value extracted in the previous step 502 is unextracted in the process of step 531, the Max performance value extracted in the previous step 502 is extracted again, and the determination process of step 503 is performed. Do.

  That is, the loop of steps 501, 503, 531, and 535 is a process for selecting a pack condition that matches the Max performance value in the pack status information table 113 as the pack condition.

  In step 503, the pack restructuring unit 151 determines that the Max performance value is larger than the allowable performance value Sp, and proceeds to step 504, where it sets the counter value N of the extraction number counter to “1”.

  Next, the pack restructuring unit 151 determines whether all the latest performance values of each secondary battery in the pack state information table 113 (FIG. 6) regarding the target pack have been extracted (505). If it is determined that all the latest performance values have been extracted, the process proceeds to step 520 (FIG. 24). If it is determined that all the latest performance values have not been extracted, the process proceeds to step 506. In this case, since no performance value is extracted from the latest performance values of each secondary battery in the pack state information table 113 (FIG. 6) regarding the target pack, the process proceeds to step 506.

  In step 506, the pack rebuilding unit 151 extracts an unextracted performance value closest to the Max performance value from the latest performance values of each secondary battery in the pack state information table 113 (FIG. 6) regarding the target pack. To do. It is assumed that the performance value extracted here is “83”.

  Next, the pack restructuring unit 151 determines whether or not the performance value extracted in step 505 is greater than the allowable performance value Sp, and whether or not the performance value is equal to or greater than (Max-A) performance value. Judgment is made (S507). If this performance value is larger than the permissible performance value Sp and equal to or greater than (Max-A) performance value, the process proceeds to step 508, and this performance value is not greater than the permissible performance value Sp or greater than (Max-A) performance value If not, the process proceeds to step 520 (FIG. 24).

  Here, if the predetermined deviation A is “3”, the performance value extracted in step 506 is “83”. Therefore, in step 507, this performance value “83” is set to the allowable performance value Sp “. It is determined that the value is larger than 80 and (Max-A) is equal to or higher than the performance value “81 (= 84-3)”.

  In step 508, the pack restructuring unit 151 adds “1” to the counter value N of the extraction number counter.

Next, the pack restructuring unit 151 determines whether or not the counter value N of the extraction number counter is equal to the number of constituent batteries N ₀ extracted in step 502 (S509). If it is determined that both are equal, it is determined that the battery pack satisfying the pack condition extracted in step 501 has been constructed, and the process proceeds to step 510 (FIG. 23). If it is determined that they are not equal, the process returns to step 505. In this case, since the counter value N is “2” and the number of constituent batteries N ₀ is “100”, it is determined that they are not equal, and the process returns to Step 505.

Hereinafter, it is determined as “NO” in step 507, that is, it is determined that the extraction performance value is not greater than the allowable performance value Sp or not greater than (Max-A) performance value, or “YES” is determined in step 509. In other words, the processing from step 505 to step 509 is repeated until it is determined that the counter value N of the extraction number counter is equal to the number of constituent batteries N ₀ .

  If the counter value N of the extraction number counter becomes “25”, the 26th performance value is extracted from the pack state information table 113 (FIG. 6) in step 506, and this performance value is “80”. To do. In this case, in step 507, it is determined that the performance value “80” is not greater than the allowable performance value Sp “80”, and is not greater than (Max-A) performance value “81 (= 84-3)”. Proceed to step 520 (FIG. 24).

  In step 520, the pack restructuring unit 151 stores “0 (normal pool)” in the state area 123a from the pool battery information table 123 shown in FIG. 14, and is equal to or less than the Max performance value and closest to the Max performance value. Extract unextracted performance values. It is assumed that the performance value extracted here is “83”. If the performance value cannot be extracted in step 520, the process proceeds to step 522.

  Thereafter, the pack restructuring unit 151 executes the same processing as Steps 507, 508, and 509 described above at Steps 521, 523, and 524.

That is, the pack restructuring unit 151 determines in step 521 whether or not the performance value extracted in step 520 is greater than the allowable performance value Sp, and whether or not this performance value is equal to or greater than (Max-A) performance value. Judge whether or not. If it is determined that this performance value is greater than the allowable performance value Sp and equal to or greater than (Max-A) performance value, “1” is added to the counter value N of the extraction number counter in step 523. Next, in step 524, it is determined whether or not the counter value N of the extraction number counter is equal to the number of constituent batteries N ₀ extracted in step 502. If it is determined that they are not equal, the process returns to step 520.

In this case, since the performance value extracted in step 520 is “83”, in step 521, this performance value “83” is larger than the allowable performance value Sp “80” and (Max−A) performance value “81 ( = 84-3) "or more, and the process proceeds to step 523. In step 523, “1” is added to the counter value N of the extraction number counter, and the counter value N becomes “26”. Next, at step 524, it is determined that the counter value N “26” of the extraction number counter is not equal to the constituent battery number N ₀ “100” extracted at step 502, and the process returns to step 520.

Hereinafter, “NO” is determined in step 521, that is, it is determined that the extraction performance value is not greater than the allowable performance value Sp or not greater than (Max-A) performance value, or “YES” is determined in step 524. In other words, the processing from step 520 to step 524 is repeated until it is determined that the counter value N of the extraction number counter is equal to the number of constituent batteries N ₀ .

If the performance value extracted from the pool battery information table 123 is “82” in step 520 after the counter value N of the extraction number counter reaches “99”, in step 521, this performance value “82”. Is greater than the allowable performance value Sp “80” and is equal to or greater than (Max-A) performance value “81 (= 84-3)”. Next, in step 523, “1” is added to the counter value N of the extraction number counter, and the counter value N becomes “100”. In step 524, it is determined that the counter value N “100” of the extraction number counter is equal to the number of constituent batteries N ₀ “100”.

If the pack rebuilding unit 151 determines “YES” in step 524, that is, if the count value N of the extraction number counter is equal to the number of constituent batteries N ₀ , it can construct a battery pack that satisfies the pack condition extracted in step 501. In step 525, the counter value N of the extraction number counter is cleared to “0”.

That is, the pack restructuring unit 151 selects 25 secondary batteries having performance values of 84 to 81 from the target pack 50 as shown in FIG. 75 secondary batteries of 83 to 82 are selected, satisfy the pack conditions selected in step 501 (allowable performance value Sp “80”, number of constituent batteries N ₀ “100”), and the maximum and minimum performance values The battery pack 51 whose deviation is “A” is reconstructed.

In step 525, when the pack reconstruction unit 151 clears the counter value N of the extraction number counter to “0”, the selling price calculation unit 145 determines the median value for the N ₀ performance values extracted above. μ and dispersion value σ ² are calculated (S526).

Next, the selling price calculation unit 145 determines from the price function table 115 shown in FIG. 8 a function corresponding to the battery type of the secondary battery incorporated in the newly reconstructed battery pack and the number of constituent batteries of this battery pack. f (μ, σ ² ) is selected (S527).

Then, the selling price calculation unit 145 has N ₀ secondary batteries by substituting the median value μ and the variance value σ ² calculated in step 526 into the function f (μ, σ ² ). The selling price of the battery pack is obtained (S528).

As described above, the function f (μ, σ ² ) stored in the price function table 115 shown in FIG. 8 reduces the median μ related to the performance values of a plurality of secondary batteries incorporated in the battery pack. On the other hand, the selling price is a function that changes every time the selling price decreases toward a specific median μ. It is also a function that the price decreases as the variance value σ ² increases.

  When the selling price is calculated by the selling price calculator 145 in step 528, the pack restructuring unit 151 creates a new record in the normal selling information table 117 (FIG. 10) regarding the target pack, The construction unit 151 and the selling price calculation unit 145 store various data in this record (S529).

  In this step 529, first, the pack rebuilding unit 151 determines a temporary pack ID related to the newly rebuilt battery pack, and stores it in the temporary pack ID area 117d in the new record of the normal sale information table 117 related to the target pack. Stores temporary pack ID. Further, the battery type of the new battery pack (= the battery type of the target pack) is stored in the battery type area 117f of this record, and the number of constituent batteries of the new battery pack is stored in the constituent battery number area 117g. The number of secondary batteries in the target battery pack to be incorporated in the new battery pack is stored in the battery number area 117h, and the selling price obtained in step 528 is stored in the selling price area 117i. Further, the minimum performance value among the performance values of the plurality of secondary batteries incorporated in the new battery pack is stored in the minimum value area 117l of this record, and incorporated in the new battery pack in the median value area 117m. A median value of performance values of a plurality of secondary batteries is stored, a dispersion value of performance values of a plurality of secondary batteries incorporated in a new battery pack is stored in a dispersion value region 117n, and a new value is stored in a serial number region 117p. The serial numbers of all the secondary batteries incorporated in a simple battery pack are stored. If the secondary battery in the new battery pack is to be incorporated into the target pack, this serial number is the serial number stored in the pack status information table 113 (FIG. 6) regarding the target pack. Alternatively, the serial number corresponds to the performance value extracted in step 505 (FIG. 22). Also, if the secondary battery in the new battery pack is a pool battery, it is the serial number stored in the pool battery information table (FIG. 14) and corresponds to the performance value extracted in step 520 (FIG. 24). Serial number

  In step 529, the selling price calculation unit 145 further adds the target pack to the selling price stored in the selling price area 117i of the normal selling information table 117 with respect to the number of constituent batteries stored in the constituent battery number area 117g. The selling price for the target pack is obtained by multiplying the ratio of the number of batteries stored in the battery count area 117h (the number of batteries in the target pack / the number of constituent batteries). Then, the selling price calculation unit 145 stores the selling price for the target pack in the selling price area 117j for the target pack in the normal selling information table 117.

Here, the pack ID of the target pack is “A100-00982”. Among the processes described above, the target pack “A100-00982” 50 as described above in the processes of steps 501 to 509 and steps 520 to 525. Then, 25 secondary batteries with performance values of 84 to 81 are selected, 75 secondary batteries with performance values of 83 to 82 are selected from the pool battery 55, and pack conditions (allowable performance value Sp “80”, Assume that the battery pack 51 satisfying the number of constituent batteries N ₀ “100”) is reconstructed.

  In this case, in step 529, the pack restructuring unit 151 determines the temporary pack ID relating to the newly reconstructed battery pack 51 as, for example, “A100-00982a”, and the normal selling information relating to the target pack “A100-00982” The temporary pack ID “A100-00982a” is stored in the temporary pack ID area 117d in the new record 117x of the table 117 (FIG. 10). Further, the battery type of the new battery pack (= the battery type of the target pack) “A” is stored in the battery type area 117f of the record 117x, and the number of constituent batteries “100” of the new battery pack is stored in the constituent battery number area 117g. And the number of secondary batteries “25” in the target battery pack to be incorporated in the new battery pack is stored in the battery number area 117h of the target pack, and the selling price “obtained” in step 528 is stored in the selling price area 117i. 68 (10,000 yen) "is stored. Further, the minimum performance value “81” among the performance values of the plurality of secondary batteries incorporated in the new battery pack is stored in the minimum value region 117l of the record 117x, and the new battery is stored in the median value region 117m. The median value “82.2” of the performance values of the plurality of secondary batteries incorporated in the pack is stored, and the dispersion value “1” of the performance values of the plurality of secondary batteries incorporated in the new battery pack is stored in the dispersion value area 117n. .2 ”and the serial numbers“ A12-X03-001,... ”Of all the secondary batteries incorporated in the new battery pack are stored in the serial number area 117p.

  In step 529, the selling price calculation unit 145 further stores the selling price “68 (10,000 yen)” stored in the selling price area 117i of the normal selling information table 117 and stored in the constituent battery number area 117g. The selling price “17 (10,000 yen)” for the target pack is obtained by multiplying the ratio (25/100) of the number of batteries “25” stored in the battery number area 117h of the target pack to the number of batteries “100”. . Then, the selling price calculation unit 145 stores the selling price “17 (10,000 yen)” for the target pack in the selling price area 117j for the target pack in the normal selling information table 117.

  When step 529 is completed, the pack restructuring unit 151 selects the performance values related to all the secondary batteries of the target pack from the latest performance values of each secondary battery in the pack status information table 113 (FIG. 6) related to the target pack. It is determined whether or not the file has been extracted (S530). If it is determined that the performance values related to all the secondary batteries have been extracted, the process proceeds to step 517 (FIG. 23). If it is determined that the performance values related to all the secondary batteries have not been extracted, the process proceeds to step 535 (FIG. 25).

  In this case, since only the performance value of “25” has been extracted from the performance values of the 100 secondary batteries in the target pack up to this stage, the performance values for all the secondary batteries in the target pack are extracted. If not, the process proceeds to step 535 (FIG. 25).

  In step 535, the pack reconstruction unit 151 determines whether all pack conditions have been selected from the pack condition ranking table 116 (FIG. 9). If all the pack conditions have been selected, the process proceeds to step 536. If all the pack conditions have not been selected, the process returns to step 501 (FIG. 22).

  In this case, up to this stage, only the pack condition of ranking “1” has been selected from the pack condition ranking table 116, and the process returns to step 501. Then, the pack rebuilding unit 151 executes the processing of steps 502 to 509 as described above.

Here, in step 501, the pack restructuring unit 151 selects the pack condition of the ranking “2” as the unextracted highest pack condition from the pack condition ranking table 116 (FIG. 9). In this case, for the convenience of the following explanation, the pack condition of ranking “9”, that is, the allowable performance value Sp “70” and the number of constituent batteries N ₀ “50” are selected from the pack condition ranking table 116 shown in FIG. Suppose that the pack condition of ranking “2” is selected.

Then, it is assumed that the pack restructuring unit 151 selects 50 secondary batteries having performance values of 80 to 77 from the target pack 50 as shown in FIG. 34 in the processing of steps 502 to 509. In this case, since the number of constituent batteries N ₀ “50” of the pack condition at this time is satisfied, the pack restructuring unit 151 determines that the counter value N of the extraction number counter is the number of constituent batteries N ₀ in step 509. If it is determined that they are equal, the process proceeds to step 510 (FIG. 23), and the counter value N of the extraction number counter is cleared to “0”.

That is, the pack restructuring unit 151 selects 50 secondary batteries having performance values of 80 to 77 from the target pack 50 as shown in FIG. A battery pack 52 that satisfies the pack conditions (allowable performance value Sp “70”, number of constituent batteries N ₀ “50”) selected in step 501 and whose deviation between the maximum value and the minimum value of the performance value is “A”. Is rebuilding.

  When the pack reconstruction unit 151 clears the counter value N of the extraction number counter to “0” in step 510, the same processing of steps 511 to 515 as the processing of steps 526 to 530 described above is performed. The

That is, when step 510 ends, the selling price calculation unit 145 calculates the median μ and the variance σ ² for the N ₀ performance values extracted above (S511), and the price function table shown in FIG. The function f (μ, σ ² ) corresponding to the newly reconstructed battery pack is selected from 115 (S512). Then, the selling price calculation unit 145 substitutes the median value μ and the variance value σ ² for this function f (μ, σ ² ), and sells the battery pack having N ₀ secondary batteries. Is obtained (S513).

  Next, the pack reconstruction unit 151 creates a new record in the normal sale information table 117 (FIG. 10) regarding the target pack, and the pack reconstruction unit 151 and the selling price calculation unit 145 store various data in this record. Store (S514).

Here, as shown in FIG. 34, when the pack ID of the target pack 50 is “A100-00982” and the processing in the second steps 501 to 509 is performed as described above, from the target pack “A100-00982” 50, It is assumed that 50 secondary batteries having performance values of 80 to 77 are selected and the battery pack 52 that satisfies the pack conditions (allowable performance value Sp “70”, number of constituent batteries N ₀ “50”) is reconstructed.

  In this case, in step 514, the pack restructuring unit 151 determines the temporary pack ID relating to the newly reconstructed battery pack 52 as, for example, “A100-00982b”, and the normal selling information relating to the target pack “A100-00982”. The temporary pack ID “A100-00982a” is stored in the temporary pack ID area 117d in the new record 117y of the table 117 (FIG. 10). Furthermore, the battery type of the new battery pack (= the battery type of the target pack) “A” is stored in the battery type area 117f of this record 117y, and the number of constituent batteries “50” of the new battery pack is stored in the constituent battery number area 117g. And the number of secondary batteries “50” in the target battery pack incorporated in the new battery pack is stored in the battery number area 117h of the target pack, and the selling price obtained in step 513 is stored in the selling price area 117i. The price “21 (10,000 yen)” is stored. Further, the minimum performance value “77” among the performance values of the plurality of secondary batteries incorporated in the new battery pack is stored in the minimum value region 117l of the record 117y, and the new value is stored in the median region 117m. The median value “78.7” of the performance values of the plurality of secondary batteries incorporated in the new battery pack is stored, and the performance of the plurality of secondary batteries incorporated in the new battery pack is stored in the dispersion value area 117n. The value dispersion value “1.1” is stored, and the manufacturing numbers “A12-X03-027,...” Of all the secondary batteries incorporated in the new battery pack are stored in the manufacturing number area 117p.

  In step 514, the selling price calculation unit 145 further stores the selling price “21 (10,000 yen)” stored in the selling price area 117i of the normal selling information table 117 and stored in the constituent battery number area 117g. The selling price “21 (10,000 yen)” for the target pack is obtained by multiplying the ratio (50/50) of the number of batteries “50” stored in the battery number area 117h of the target pack to the number of batteries “50”. . Then, the selling price calculation unit 145 stores the selling price “17 (10,000 yen)” for the target pack in the selling price area 117j for the target pack in the normal selling information table 117.

  When step 514 is completed, the pack restructuring unit 151 performs performance values related to all the secondary batteries of the target pack from the latest performance values of each secondary battery in the pack status information table 113 (FIG. 6) related to the target pack. Whether or not is extracted is determined (S516). If it is determined that the performance values for all the secondary batteries have been extracted, the process proceeds to step 517. If it is determined that the performance values for all the secondary batteries have not been extracted, the process proceeds to step 502 (FIG. 22).

  In this case, since only the performance value of “75 (= 25 + 50)” has been extracted from the performance values of the 100 secondary batteries in the target pack up to this stage, all the secondary batteries in the target pack are related. It is determined that the performance value has not been extracted, and the process proceeds to step 502 (FIG. 25). Then, the pack rebuilding unit 151 executes the processing of steps 502 to 509 as described above.

  Assume that the pack restructuring unit 151 selects 25 secondary batteries having performance values of 76 to 74 from the target pack 50 as shown in FIG. 34 in the third processing of steps 502 to 509. In this case, 25 secondary batteries are selected from the target pack 50 in the first processing of steps 502 to 509, and 50 secondary batteries of the target pack 50 are selected in the second processing of steps 502 to 509. Is selected, and 25 secondary batteries are selected from the target pack 50 in the processing of the steps 502 to 509 for the third time. Therefore, 100 secondary batteries constituting the target pack 50 are All are selected. For this reason, when 25 secondary batteries are selected from the target pack 50 in the processing of Steps 502 to 509 for the third time, in Step 505, the pack restructuring unit 151 selects each of the pack status information tables 113 (FIG. 6). It is determined that all the latest performance values of the secondary battery have been extracted, and the process proceeds to step 520 (FIG. 24).

Assume that the pack restructuring unit 151 selects 23 secondary batteries having performance values of 76 to 73 from the pool battery 55 as shown in FIG. 34 in the processing of steps 520 to 524 described above. In this case, as described above, 25 secondary batteries having performance values of 76 to 74 are selected from the target pack 50 in the third processing of steps 502 to 509, so that the counter value of the extraction number counter is “ 48 (= 25 + 23) ”, but this counter value does not reach the number N ₀ “ 50 ”of the pack conditions. Thus, pack reconstruction unit 151, the processing of step 524, the counter value N of the number of extracted counter as not equal to configure cell number N _0, the flow returns to step 520. Here, the pack restructuring unit 151 has a performance value lower than the previously extracted performance value “73” as an unextracted performance value that is not more than the Max performance value “76” and is closest to the Max performance value “76”. Assume that “72” is extracted.

  The pack restructuring unit 151 determines whether or not the extracted performance value “72” is larger than the allowable performance value Sp “70” in step 521, and (Max-A) performance value “73 (= 76-3). It is determined whether or not the above is exceeded. In this case, the pack restructuring unit 151 determines that the extracted performance value “72” is not equal to or greater than (Max-A) performance value “73 (= 76-3)”, and proceeds to step 522. That is, when there is no secondary battery that satisfies the determination condition of step 521 in the pool battery, the process proceeds to step 522.

In step 522, the pack restructuring unit 522 performs step 521 regarding the shortage “N ₀ −N (2 = 50−48)” of the number N of the extracted performance values with respect to the number of constituent batteries N ₀ “50”. Assuming that the performance value of the minimum condition can be extracted under the determination condition, the process proceeds to step 525. In this case, regarding the two shortages, it is assumed that both are (Max-A) performance value “73 (= 76-3)”.

That is, the pack rebuilding unit 151 selects 25 secondary batteries having performance values of 76 to 74 from the target pack 50 as shown in FIG. Through the processes in steps 520 to 524, 23 secondary batteries having performance values of 76 to 73 are selected from the pool battery 55. However, since there is no secondary battery that satisfies the determination condition of step 521 in the pool battery 55, the secondary battery of the shortage “2” with respect to the number of constituent batteries N ₀ “50” is the minimum condition in the determination condition. That is, assuming that the performance value is “73”, a virtual battery pack that satisfies the pack conditions (allowable performance value Sp “70”, number of constituent batteries N ₀ “50”) is constructed.

  When the processing reaches step 525 through step 522, the pack reconstruction unit 151 clears the counter value N of the extraction number counter to “0” as described above. Then, similarly to the above, the processing of steps 526 to 530 is executed.

However, in this case, in step 526, when the selling price calculation unit 145 calculates the median value μ and the variance value σ ² of the performance values, the secondary battery is assumed to be present with the performance value actually extracted. The median value μ and the variance value σ ² of the performance values including the performance value of are calculated. In step 529, the pack restructuring unit 151 stores the data related to the virtual battery pack in the new record 117z of the normal sale information table 117 (FIG. 10), in the hold flag area 117e of the new record 117z. “1” is stored. As described above, “1” means that the battery pack indicated by the data in the record 117z cannot be sold immediately on the transaction management side. Further, the pack rebuilding unit 151 determines in step 530 that all performance values of the secondary batteries of the target pack have been extracted, and proceeds to step 517.

  In step 517, the selling price calculation unit 145 adds up all the prices stored in the selling price area 117j for the target pack in the normal selling information table 117 (FIG. 10) related to the target pack, and the normal selling of the target pack is performed. Ask for a price. In this case, “17 (10,000 yen)”, “21 (10,000 yen)”, and “9 (10,000 yen)” are stored in the selling price area 117j for the target pack in the normal selling information table 117. Are summed up to obtain the normal selling price “47 (10,000 yen)” of the target pack.

  Next, the selling price calculation unit 145 stores the normal selling price “47 (10,000 yen)” of the target pack obtained in step 516 in the selling price area 117b of the normal selling information table 117 (FIG. 10) regarding the target pack. (S518), a series of processing ends.

  Incidentally, as described above, when the pack restructuring unit 151 determines in step 530 (FIG. 24) that all the performance values of the secondary batteries of the target pack have not been extracted, the pack restructuring unit 151 further performs step 531 (FIG. 22). ), When the extracted Max performance value is treated as unextracted from the performance values of each secondary battery of the target pack, that is, the unextracted performance value among the performance values of each secondary battery of the target pack is If it exists, a determination process is performed in step 535 (FIG. 25).

  If it is determined in step 535 that all pack conditions have not been selected from the pack condition ranking table 113, the pack restructuring unit 151 returns to step 501 (FIG. 22). If it is determined in step 535 that all the pack conditions have been selected from the pack condition ranking table 113, the pack restructuring unit 151 refers to the pack status information table 113 (FIG. 6) regarding the target pack. The battery production number of the unextracted performance value is specified among the performance values of each secondary battery of the target pack (S536). Then, the pack restructuring unit 151 stores “2 (discard)” in the state area 123d corresponding to the serial number identified in step 536 in the state area 123d of the pool battery information table 123 (S537).

  That is, when it is determined in step 535 that all pack conditions have been selected from the pack condition ranking table 113 even though there are unextracted performance values among the performance values of each secondary battery of the target pack. In this case, the unextracted performance value does not satisfy any of the pack conditions. Therefore, in this embodiment, in such a case, the secondary battery having this performance value is disposed of.

  Note that the secondary battery in which “2 (discard)” is stored in the state area 123d of the pool battery information table 123 becomes the target of the discard completion reception process described above with reference to FIG.

  Upon completion of step 537, the pack restructuring unit 151 deletes all records including the production number specified in step 536 from the normal selling information table 117 (FIG. 10) and the normal buying information table 118 (FIG. 11). Terminate the process.

  This is the end of the description of the normal selling price calculation and the pack restructuring process in step 50 of FIG.

  Next, the calculation of the auction selling price and the pack restructuring process in step 50 of FIG. 20 will be described with reference to the flowcharts shown in FIGS.

  In the process related to the auction sale, steps 501 to S510, steps 511a to 514a, and step 516 corresponding to steps 501 to 514, steps 516 to 518, and steps 520 to 538 in the process related to the normal sale shown in FIGS. To 518, step 520a, steps 521 to 525, steps 526a to 529a, steps 530 to 537, and step 538a are executed.

  Of the above-described steps related to the auction sale, steps 501 to S510, steps 516 to 518, step 520a, steps 521 to 525, steps 530 to 537, and step 538a are basically the same as the corresponding steps in the process related to normal selling. The same processing is executed.

  However, in step 520a during the process related to the auction sale, the process for the normal pool battery is executed in step 520 during the process related to the normal sale, whereas the process is executed for the auction pool battery. Is different. Further, in step 538a during the process related to the auction sale, the process for the normal sale information table 117 and the normal buy information table 118 is executed in step 538 during the process related to the normal sale, whereas the auction pool sale information is displayed. The difference is that the processing is executed for the table 121 and the auction purchase information table 122.

  Steps 501 to S510, steps 516 to 518, step 520a, steps 521 to 525, steps 530 to 537, and step 538a are all steps processed by the pack reconstruction unit 151.

  On the other hand, among the above steps related to the auction sale, steps 511a to 514a and steps 526a to 529a are executed in a process greatly different from the corresponding step in the process related to the normal sale. The above steps 511a to 514a and steps 526a to 529a are all processed by the selling price calculation unit 145 or the pack restructuring unit 151 and the selling price calculation process 145.

  That is, in the process related to auction sales, the pack reconstruction method by the pack rebuilding unit 151 is basically the same as the process related to normal selling, but the selling price calculation method by the selling price calculation unit 145 is the same as the normal selling process. The processing is different.

  Hereinafter, the processing contents in steps 511a to 514a and steps 526a to 529a, which are different from the corresponding steps in the processing related to the normal selling, among the steps in the processing related to the auction selling will be mainly described.

In the processing of steps 501 to 509, the pack rebuilding unit 151 extracts the performance value for the number of constituent batteries N ₀ from the performance values of each secondary battery of the target pack, and a new battery pack is rebuilt. When the counter value N of the extraction number counter is cleared to “0” in step 510, the selling price calculation unit 145 and the pack restructuring unit 151 execute the following steps 511a to 513a.

The selling price calculation unit 145 first calculates (μ (median value), σ ² (dispersion value)) of the performance value for the number of constituent batteries N ₀ extracted by the pack restructuring unit 151, and this (μ, and σ ^2), (μ of each record in the auction record table 124 shown in FIG. 15, obtains the similarity between σ ²⁾ (S511a).

There are various methods for obtaining the degree of similarity. Here, for example, the degree of similarity is obtained by a vector space method. Specifically, pack reconstruction unit 151 configured cell number N ₀ minutes extracted by the performance value (μ, σ ²⁾ was used as a vector X, the performance value in an auction record table (μ, σ ²⁾ the As the vector Y, the similarity cos θ is obtained by the following equation.

cos θ = <X, Y> / {[X] · [Y]}
In the above formula, <X, Y> is the inner product of the vectors X and Y, and [X] and [Y] are the lengths of the vectors.

  The degree of similarity cos θ is “1” when the two compared are most similar, and is “0” when they are not similar at all.

Next, the selling price calculation unit 145 extracts a record having a similarity (μ, σ ² ) equal to or higher than a predetermined value from all the records in the auction performance table 124 (S512s).

  Next, the selling price calculation unit 145 obtains the average value Sa of the similarities of each extracted record and the average value Pa of the auction actual purchase price in each extracted record. Subsequently, the selling price calculation unit 145 converts the average value Pa of the auction performance buying price into the buying price of the degree of similarity using the function g (S, P) having the similarity S and the buying price P as parameters. . Then, for example, the purchase price based on the actual result is multiplied by “0.8” to obtain the auction selling price obtained by subtracting the margin from the purchase price based on the actual result (S513a).

  When the selling price calculation unit 145 calculates the auction selling price in step 513a, the pack restructuring unit 151 performs the auction selling related to the target pack basically in the same manner as the processing in step 514 during the processing related to normal selling. A new record is created in the information table 121 (FIG. 12), and the pack reconstruction unit 151 and the selling price calculation unit 145 store various data in this record (S514a).

In addition, the performance value for the number of constituent batteries N ₀ is extracted by the processing of steps 501 to 509 and the processing of steps 520a to 524, and a new battery pack is reconstructed. In step 525, the counter of the extraction number counter When the value N is cleared to “0”, the selling price calculation unit 145 and the pack reconstruction unit 151 execute the following steps 526a to 529a.

  The processing in these step steps 526a to 529a is the same as the processing in steps 511a to 514a described above. For this reason, the description regarding the process in these step steps 526a to 529a is omitted.

  This is the end of the calculation of the auction selling price and the pack restructuring process in step 50 of FIG.

  Next, a method for calculating the future normal selling price and a method for calculating the future auction selling price in step 51 of FIG. 21 will be described.

First, a method for calculating the future normal selling price will be described.
The future selling price prediction unit 148 first extracts the latest performance value for each secondary battery from the pack state information table 113 of the target pack, and obtains the median value and the variance value thereof. Further, the latest change coefficient for each secondary battery is extracted from the pack state information table 113 of the target pack, and the median of these is also obtained.

  Next, the future selling price prediction unit 148 predicts the median of the performance values at a plurality of future points in time, assuming that the median of the performance values will change by the change coefficient corresponding to the passage of time. Furthermore, based on the change tendency of the variance value with the passage of time, which is grasped in advance, the variance value at each future time point is predicted.

Subsequently, the future selling price prediction unit 148 selects a function f (μ, σ ² ) corresponding to the target pack from the price function table 115 (FIG. 8). Then, the future selling price prediction unit 148 substitutes the median value μ and the variance value σ ² at each future time point obtained previously into this function f (μ, σ ² ), and at each future time point. Ask for the selling price.

  The selling price at each future time point obtained as described above is reflected in the price graph 36a in FIG.

Next, a method for calculating the future auction selling price will be described.
The future selling price prediction unit 148 first obtains the median value and the variance value regarding the latest performance value for each secondary battery in the pack state information table 113 of the target pack, similarly to the method for calculating the future normal selling price. Then, the median value regarding the latest change coefficient for each secondary battery in the pack state information table 113 is obtained. Furthermore, using the median of the coefficient of change related to the performance value and the median of the performance value, the median of the performance value at multiple future time points is predicted, and using the change trend and the variance value related to the variance value, Predict variance values at multiple future times. Here, assuming that the next month is January, the multiple points in the future are the last day of January, the last day of March, the last day of May, the last day of July, and the last day of September.

Next, the future selling price prediction unit 148 extracts all the past January and February records from the auction performance table 124, and (μ, σ ² ) of these records and the future end of January ( The degree of similarity with μ, σ ² ) is obtained. And the record whose similarity is more than predetermined is extracted from all the past records of January and February.

  Next, the future selling price prediction unit 148 obtains the average value Sa of the similarities of each record having a similarity degree equal to or higher than the predetermined value and the average value Pa of the auction actual purchase price in each record having a similarity degree equal to or higher than the predetermined value. Subsequently, the future selling price prediction unit 148 converts the average value Pa of the actual auction purchase price into the purchase price of the degree of similarity using the function g (S, P) described above. Then, for example, the purchase price based on the actual result is multiplied by “0.8” to obtain the auction sale price obtained by subtracting the margin from the purchase price based on the actual result. Set to the median.

  Further, the future selling price predicting unit 148 further extracts a record having the highest auction purchase actual price from the records having a similarity equal to or higher than a predetermined value, and calculates the similarity of this record and the auction purchase actual maximum price as described above. By substituting it into the function g (S, P), the auction purchase actual maximum price is converted into a similarity measure. Then, the maximum auction selling price obtained by subtracting the margin from the auction buying actual maximum price is obtained, and this is set as the maximum auction selling price at the end of January in the future.

  Further, the future selling price predicting unit 148 further extracts a record having the smallest auction purchase actual price from among the records having a similarity equal to or higher than a predetermined value, and calculates the similarity of the record and the auction purchase actual minimum price as described above. By substituting it into the function g (S, P), the auction purchase actual minimum price is converted into a similarity measure. Then, a minimum auction selling price obtained by subtracting a margin from the auction buying actual minimum price is obtained, and this is set as the minimum value of the auction selling price at the end of January in the future.

  As described above, the future selling price prediction unit 148 obtains the median, maximum, and minimum values of the auction selling price on the end of January in the future. Similarly, the future selling price prediction unit 148 obtains the median, maximum, and minimum values of the auction selling price on the last day of March, the last day of May, the last day of July, and the last day of September.

  The median value, maximum value, and minimum value of the auction selling price at each future time point determined as described above are reflected in the price graph 36b in FIG.

  Next, processing when a normal sale is received from the user will be described with reference to the flowchart shown in FIG.

  As described above with reference to FIG. 32, when the user clicks the execute button 50 after clicking the sell button 39a in the display screen 30a for normal sale information, the user can select the battery pack he / she owns. The pack ID, the fact that the battery pack is normally sold, the pack ID that is designated for purchase, and the fact that the battery pack of the pack ID is normally bought are transmitted to the transaction management apparatus 100.

  The process described below is started when the transaction management apparatus 100 receives from the user the fact that the battery pack is normally sold together with the pack ID of the battery pack that the user owns. At this time, since the transaction management apparatus 100 also receives from the user the fact that the battery pack with the pack ID is normally purchased together with the pack ID specified for purchase, the processing when accepting the normal purchase, which will be described later, is performed. This process is executed before or after this process or in parallel with this process.

  When the transaction accepting unit 144 of the transaction management apparatus 100 accepts the fact that the battery pack is normally sold and the pack ID of the battery pack via the communication control unit 161 (S60), the response processing unit 155 To the seller, the fact that the battery pack has been sold and sold, and the delivery information of the battery pack are transmitted via the communication control unit 161 (S61). Here, the delivery information includes a battery pack delivery method, a battery pack selling price remittance method, and the like.

  Next, the table creation / change unit 142 of the transaction management apparatus 100 stores information on the target pack in the pool battery information table 123 (FIG. 14) (S62).

  First, the table creating / changing unit 142 refers to the pack state information table 113 (FIG. 6) corresponding to the sale target pack, and the pool battery information table 123 (FIG. 14) includes the second pack included in the sale target pack. Create new records for the number of secondary batteries. Then, the production number of the secondary battery in the target pack is stored in the production number area 123a of these records, and the date and time when the sale of the target pack is accepted is stored in the pool date and time area 123b of these records. The performance value of the secondary battery in the target pack is stored in the performance value area 123c of the record. This performance value is the latest performance value among the performance values in the performance value area 113c of the pack state information table 113. Further, the table creation / change unit 142 stores “0 (normal pool)” in the state area 123d of these records.

  Next, the buying price calculation unit 149 obtains the buying price of the reconstructed pack from the selling price in the temporary pack information area 117c of the normal pack information table 117 (FIG. 10) of the target pack (S63). At this time, the purchase price calculation unit 149 stores “0 (sells immediately on the transaction management side)” in the hold flag area 117e from the record in the temporary pack information area 117c of the normal sale information table 117 (FIG. 10). Extract all records that are present. Then, the selling price is extracted from the selling price area 117i in these records, and the selling price is multiplied by, for example, 1.2, and a margin is added to obtain a buying price for these selling prices.

  Next, the buying / selling information creation unit 152 is for other users based on the information stored in the temporary pack information area 117c of the target pack normal selling information table 117 (FIG. 10) and the buying price obtained in step 63. Is created and stored in the normal buying information table 118 (FIG. 11) (S64).

  The sales information creation unit 152 first extracts all records in which “0 (sell immediately on the transaction management side)” is stored in the hold flag area 117e of the temporary pack information area 117c of the normal sale information table 117 (FIG. 10). At the same time, records corresponding to the number of extracted records are created in the normal purchase information table 118 (FIG. 11).

  The reason why the record in which “0 (cannot be sold immediately on the transaction management side)” is stored in the hold flag area 117e is not extracted is that the information of this record is information on the virtual battery pack that could not be actually constructed. This is because it cannot be handled as buying information for other users.

  Next, the trading information creation unit 152 stores all the temporary pack IDs stored in the temporary pack ID area 117c in each extracted record that are not stored in the pack management table 111, the pack condition information table 112, or the like. The official pack ID is changed to the stored pack ID, and this formal pack ID is stored in the target pack ID area 118d in the new record of the normal purchase information table 118 (FIG. 11).

  Next, the buying / selling information creation unit 152 includes a battery type area 117f, a constituent battery number area 117g, a minimum value area 117l, a median value area 117m, and a variance value area 117n in the record extracted from the normal sale information table 117 (FIG. 10). , The data stored in the serial number field 117p, the battery type area 118f, the constituent battery number area 118g, the minimum value area 118l, the median value area 118m, the variance value area 118n, the manufacture, The number is stored in the number area 118p.

  Further, the buying and selling information creating unit 152 stores the buying price for each record obtained in step 63 in the buying price area 118i in the corresponding record of the normal buying information table 118. This completes the creation and storage of normal purchase information for other users. Here, the normal purchase information for other users is information stored in each new record in the normal purchase information table 118.

  Here, the creation and storage of normal purchase information for other users will be specifically described.

  The trade information creation unit 152 stores all records 117x and 117y in which “0 (sell immediately on the transaction management side)” is stored in the hold flag area 117e of the temporary pack information area 117c of the normal sale information table 117 (FIG. 10). Extract. Then, two extracted records 118x and 118y are created in the normal purchase information table 118 (FIG. 11).

  Next, the buying and selling information creating unit 152 stores the information in the two records 117x and 117y extracted from the normal selling information table 117 in new records 118x and 118y of the normal buying information table 118. However, the information here is the battery type, the number of constituent batteries, the minimum value of the performance value, the median value of the performance value, the dispersion value of the performance value, and the serial number. Further, using the selling prices (680,000 yen, 210,000 yen) in the two records 117x and 117y extracted from the normal selling information table 117, the buying price obtained in step 62 (810,000 yen, 250,000 yen) Are stored in the buying price area 118i in the new records 118x and 118y of the normal buying information table 118. This completes the creation and storage of normal purchase information for other users.

  Note that the records 118v and 118w in the normal purchase information table 118 (FIG. 11) are records created in the acceptance process of a new registration application relating to a battery pack that is not fixed to which application device.

  When the creation and storage of the purchase information for other users is completed, the table creation / change unit 142 performs the pack condition information table 112, the pack state information table 113, the normal sale information table 117, and the auction sale information regarding the sale target pack ID. The table 121 is deleted (S65). These tables are deleted when the user's battery pack is sold to the transaction management side, and the secondary battery in the battery pack is actually used as a new battery pack for purchase. This is because information about the battery pack is basically unnecessary.

  This completes the process when accepting a normal sale from the user.

  Next, processing when a normal purchase is accepted from the user will be described with reference to the flowchart shown in FIG.

  As described above, this process is started when the transaction management apparatus 100 receives from the user a message indicating that the battery pack of the pack ID is normally purchased together with the pack ID specified for purchase.

  When the buying and selling acceptance unit 144 of the transaction management apparatus 100 accepts that the battery pack is normally purchased and the pack ID of the battery pack via the communication control unit 161 (S70), the response processing unit 155 accepts the received pack. It is determined whether or not the ID is in the normal purchase information table 118 (FIG. 11) (S71).

  If the response processing unit 155 determines that the received pack ID is not in the normal purchase information table 118, the response processing unit 155 transmits a message indicating that the sale has not been established to the buyer via the communication control unit 161 (S72), and performs a series of processing. finish. Further, when the response processing unit 155 determines that the received pack ID is in the normal purchase information table 118, the response processing unit 155 transmits to the buyer via the communication control unit 161, information indicating the completion of the sale and delivery of the battery pack. (S73)

  By the way, the condition for the fact that the user buys a pack ID designated for buying and the fact that the battery pack of the pack ID is normally bought is transmitted to the transaction management apparatus 100 is that the user displays the normal buying and selling information display screen 30a shown in FIG. And specify a pack ID displayed as a battery pack that can be purchased. That is, when the user side sends a message indicating the normal purchase of the battery pack of the pack ID to the transaction management apparatus 100 together with the pack ID specified for purchase, basically, the transaction management side sets the battery pack of the pack ID. Should be present.

  However, in the present embodiment, secondary batteries once stored as pool batteries in the pool battery information table 123 (FIG. 14) are used redundantly so that as many battery packs as possible can be reconstructed. I can do it. For this reason, even if a certain user looks at the display screen 30a of the normal buying and selling information shown in FIG. 32 and designates the pack ID displayed as a battery pack that can be bought there, When one secondary battery is used to reconstruct another battery pack, and another user buys this other battery pack before one user designates the battery pack In this case, this battery pack cannot exist.

  Therefore, in the present embodiment, when the fact that the battery pack is normally purchased and the pack ID of this battery pack are received (S70), in step 71, whether the received pack ID is in the normal purchase information table 118 (FIG. 11). Judgment is made whether or not.

  When the response processing unit 155 notifies the buyer of battery pack delivery information or the like (S73), the table creation / change unit 142 changes the buyer's record in the pack management table 111 (S74).

  The table creation / change unit 142 identifies the buyer record in the pack management table 111 (FIG. 4) from the buyer ID (owner ID). Then, the pack ID received in step 70 is stored in the pack ID area 111b in the record.

  In this embodiment, when the owner of the battery pack sells this battery pack, the record of the owner in the pack management table 111 is not changed. This is because, in this embodiment, selling and buying of battery packs are linked, so when the owner of the battery pack sells this battery pack and the owner purchases a new battery pack, pack management is performed. This is because the record of the owner in the table 111 is changed.

  In the present embodiment, a person whose owner ID is not registered in the pack management table 111 is structured such that a battery pack cannot be purchased from the transaction management side. There is no processing to add this person's record. When a person whose owner ID is not registered in the pack management table 111 purchases a battery pack, in this embodiment, the battery pack is purchased together with the application device in a state where the battery pack is mounted on the application device. It is assumed that In this case, the owner shown in FIG. 18 relates to the record in the pack management table 111 relating to the battery pack that the seller 6 (FIG. 1) selling the application device in which the battery pack is mounted has previously applied for new registration. Will apply for change processing.

  Next, the table creation / change unit 142 creates a pack condition information table 112, a pack status information table 113, a normal sale information table 117, and an auction sale information table 118 regarding the purchase target pack ID (S75). At this point, data is stored in the pack ID area 113a and the production number area 113b of the created pack status information table 113 (FIG. 6), but the other areas 113e, 113c, and 113d are blank. It is. The target pack ID areas 117a and 118a of the normal sale information table 117 and the auction sale information table 121 store data, but the other areas are blank.

  Next, the table creation / change unit 142 deletes all records including the manufacturing number of the secondary battery included in the purchase target pack from the normal purchase information table 118 and the pool battery information table 123 (S76), A series of processing ends.

  In addition, before handing over the battery pack that the user bought to the user, the transaction management side takes out all the secondary batteries to be incorporated into the battery pack from the secondary batteries pooled in the warehouse, etc. The battery pack for the user is assembled using the secondary battery. At this time, the transaction management side adjusts the CMU or BMU incorporated in the pooled battery pack to match the application device owned by the user, and the adjusted CMU or BMU is adjusted. Incorporate into the battery pack for the user.

  The above work on the transaction management side is performed by, for example, the sales agency 6 belonging to the transaction management side.

  Next, according to the flowchart shown in FIG. This process starts at the start of bidding for the auction purchase target pack, as described below.

  The bid management unit 154 of the transaction management apparatus 100 refers to the bid end area 125d of the bid information table 125 shown in FIG. 16 and determines whether or not the bid period has ended for each auction purchase target pack ( S80). As described above with reference to FIG. 21, the bid information table 125 related to the auction purchase target pack is displayed in the auction bid information for display that the bid management unit 154 creates in the auction purchase information for sale created by the buying and selling information creation unit 152 in step 53. It is created when it is determined that information on a new battery pack for which no period has been set is included. The bidding start of the auction purchase target pack is when the display auction buying / selling information including the display auction buying information related to this pack is transmitted to the user side for the first time.

  On the user side, this display auction buying / selling information is displayed. As described above with reference to FIG. 33, the user who views this information specifies the purchase target pack ID in the information display screen 30b and inputs the bid price, and then clicks the execution button 50. Then, the user side transmits to the transaction management device 100 information on the auction purchase of the battery pack of the pack ID together with the purchase target pack ID and the bid price. Further, at this time, the fact that the battery pack is sold by auction is transmitted to the transaction management apparatus 100 together with the pack ID of the battery pack owned by the user.

  In the transaction management device 100, the transaction management device 100 receives the auction purchase of the battery pack from the user who wishes to participate in the auction together with the purchase target pack ID and the bid price. At this time, the transaction management apparatus 100 also receives from the user side the auction sale of the battery pack together with the pack ID of the battery pack owned by the user, and therefore accepted the auction sale described later. This process is executed before or after this process or in parallel with this process.

  The bid management unit 145 determines, in step 80, that the battery acceptance unit 144 has determined that the auction has been purchased, the pack ID of the battery pack, and the battery pack for which the bidding period has not ended, via the communication control unit 161. When the bid price is received (S81), the bidder ID and bid price are stored in the bid information table 125 (FIG. 16) regarding the battery pack (S82). At this time, the bid management unit 145 obtains an owner ID corresponding to the communication address of the transmission source indicating the auction purchase from the pack management table 111 (FIG. 4), and uses this as the bidder ID to set the bid information table 125. To store.

  When the bid management unit 145 stores the bidder ID and the bid price in the bid information table 125 (S82), the process returns to step 80 again.

  When the bid management unit 145 determines in step 80 that the bidding period has ended with respect to any of the auction purchase target packs in which the bid information table 125 is provided, the bid information table 125 related to this battery pack is displayed in the bid information table 125. It is determined whether or not a record exists (S83).

  When the bid management unit 145 determines that there is no record such as a bidder in the bid information table 125, that is, there is no bidder, the bid management unit 145 sets “1 (automatic extension)” to the automatic extension flag area 125b of the bid information table 125. Is stored (S84).

  When the bid management unit 145 determines that “1 (automatic extension)” is not stored in the automatic extension flag area 125b, the series of processes is immediately ended. On the other hand, when the bid management unit 145 determines that “1 (automatic extension)” is stored in the automatic extension flag area 125 b, the bid end date and time stored in the bid end area 125 d of the bid information table 125 is displayed. For example, the change is made after one week (S85), and the process returns to step 80.

  When the bid management unit 145 determines in step 83 that there is a record of a bidder or the like in the bid information table 125, that is, there is a bidder, the bidder who has the highest bid price among the records in the bid information table 125. The ID is grasped (S90).

  When the bid management unit 145 grasps the bidder ID of the highest bid price, the response processing unit 155 sends “other bidders other than the bidder with this bidder ID” to the other bidders via the communication control unit 161. "Successful bid could not be made" is transmitted, and the process proceeds to step 93 (S91).

  Furthermore, when the bid management unit 145 grasps the bidder ID of the highest bid price, the response processing unit 155 notifies the bidder of this bidder ID, that is, the winning bidder, via the communication control unit 161. “Successful bid” and battery pack delivery information are transmitted, and the process proceeds to step 93 (S92).

  In step 93, the table creation / change unit 142 changes the successful bidder record in the pack management table 111. At this time, the table creation / change unit 142 specifies the record of the winning bidder in the pack management table 111 (FIG. 4) from the winning bidder ID (owner ID). Then, the pack ID received in step 81 is stored in the pack ID area 111b in the record.

  Next, the table creation / change unit 142 creates a pack condition information table 112, a pack status information table 113, a normal sale information table 117, and an auction sale information table 118 related to the auction purchase target pack ID (S94). At this point, data is stored in the pack ID area 113a and the production number area 113b of the created pack status information table 113 (FIG. 6), but the other areas 113e, 113c, and 113d are blank. It is. The target pack ID areas 117a and 118a of the normal sale information table 117 and the auction sale information table 121 store data, but the other areas are blank.

  At this time, the table creating / changing unit 142 creates a new table in the auction performance table 124 (FIG. 15), and stores information related to the battery pack for which the auction has been established.

  Next, the table creation / change unit 142 deletes the bid information table 125 related to the auction purchase target pack, and from the auction purchase information table 122 and the pool battery information table 123, the secondary information included in the auction purchase target pack. All records including the battery production number are deleted (S95), and the series of processes is terminated.

  Next, processing when accepting an auction sale from a user will be described according to the flowchart shown in FIG.

  As described above, this process starts when the transaction management apparatus 100 receives from the user the fact that the battery pack is auctioned together with the pack ID of the battery pack owned by the user. .

  The response processing unit 155 of the transaction management apparatus 100 receives the battery pack auction sale and the pack ID of the battery pack via the communication control unit 161 (S100). The information that the auction sale of the battery pack has been established and the delivery information of the battery pack are transmitted to the seller via the communication control unit 161 (S101).

  Next, the table creation / change unit 142 of the transaction management apparatus 100 stores information on the auction sale target pack in the pool battery information table 123 (FIG. 14) (S102).

  First, the table creating / changing unit 142 refers to the pack state information table 113 (FIG. 6) corresponding to the auction sale target pack, and the pool battery information table 123 (FIG. 14) is included in the auction sale target pack. Create new records for the number of secondary batteries. Then, the production number of the secondary battery in the target pack is stored in the production number area 123a of these records, and the date and time when the sale of the target pack is accepted is stored in the pool date and time area 123b of these records. The performance value of the secondary battery in the target pack is stored in the performance value area 123c of the record. This performance value is the latest performance value among the performance values in the performance value area 113c of the pack state information table 113. Further, the table creation / change unit 142 stores “1 (auction pool)” in the state area 123d of these records.

  Next, the buying price calculation unit 149 obtains an auction buying reference price from the selling price in the temporary pack information area 121c of the target pack auction selling information table 121 (FIG. 12) (S103). At this time, the purchase price calculation unit 149 reads all records in which “0 (sell immediately on the transaction management side)” is stored in the hold flag area 121e from the records in the temporary pack information area 121c of the auction sale information table 121. Extract. Then, the selling price is extracted from the selling price area 121i in these records, and the selling price is multiplied by, for example, 1.2, and a margin is added to obtain the auction buying reference price for these selling prices. .

  Next, the buying / selling information creation unit 152 performs other processing based on the information stored in the temporary pack information area 121c of the auction sale information table 121 (FIG. 12) of the target pack and the auction purchase reference price obtained in step 103. User auction buying information is created and stored in the auction buying information table 122 (FIG. 13) (S104).

  The sales information creation unit 152 first extracts all records in which “0 (sell immediately on the transaction management side)” is stored in the hold flag area 121e of the temporary pack information area 121c of the auction sales information table 121 (FIG. 12). At the same time, records corresponding to the number of extracted records are created in the auction purchase information table 122 (FIG. 13).

  Next, the buying / selling information creation unit 152 stores all the temporary pack IDs stored in the temporary pack ID area 121c in each extracted record that are not stored in the pack management table 111, the pack condition information table 112, or the like. The official pack ID is changed to the stored pack ID, and the official pack ID is stored in the target pack ID area 122d in the new record of the auction purchase information table 122 (FIG. 13).

  Next, the sale information creation unit 152 stores the information in the record extracted from the auction sale information table 121 in a new auction purchase information table 122. However, the information here is the battery type, the number of constituent batteries, the minimum value of the performance value, the median value of the performance value, the dispersion value of the performance value, and the serial number.

  Further, the buying and selling information creating unit 152 stores the auction buying reference price for each record obtained in step 103 in the buying price area 122 i in the corresponding record of the auction buying information table 122. This completes the creation and storage of auction purchase information for other users.

  When the creation and storage of the purchase information for other users is completed, the table creation / change unit 142 performs the pack condition information table 112, the pack state information table 113, the normal sale information table 117, and the auction sale information regarding the sale target pack ID. The table 121 is deleted (S105).

  This completes the process when accepting an auction sale from the user.

  As described above, in the present embodiment, a large number of secondary batteries pooled by the transaction management side are used to temporarily reconstruct a large number of battery packs satisfying various pack conditions, and this is purchased for the user. Since it is presented as a pack, it is possible to present various battery packs with different performance, price, etc. to those who wish to purchase the battery pack. That is, according to the present embodiment, many options can be presented to a person who wishes to purchase a battery pack.

  Further, in the present embodiment, a battery pack having stricter packing conditions using a plurality of secondary batteries in a battery pack owned by the user and a large number of secondary batteries pooled by the transaction management side, that is, If a battery pack that sells well is rebuilt and the price of the secondary battery owned by the user in this battery pack is used as the selling price of the battery pack owned by the user, a higher selling price is given to the seller of the battery pack. Can be presented.

  Moreover, since the transaction management apparatus 100 of this embodiment also accepts auction sales in addition to normal sales, the owner of the battery pack can select various forms regarding the sales of the battery pack.

  Next, various modifications of the embodiment described above will be described.

"Modification of pack reconstruction process"
A modification of the selling price calculation and pack reconstruction process (S50) shown in FIG. 21 will be described with reference to the flowcharts shown in FIGS.

  In this modification, the selling price calculation and pack restructuring process (S50) is processed by two routines. One routine is a routine for executing a selling price calculation process for calculating the selling price of the target pack, and the other one is a routine for executing a buying price calculation and a pack restructuring process.

  First, a routine for executing the purchase price calculation and pack restructuring process will be described with reference to the flowcharts shown in FIGS.

First, the pack restructuring unit 151 refers to the pack condition information table 112 of the target pack and grasps the allowable performance value Sp and the number of constituent batteries N ₀ of the target pack (S550).

  Next, the pack restructuring unit 151 can extract a record with a performance value that stores “0 (normal pool)” in the state area 123a and is larger than the allowable performance value Sp from the pool battery information table 123 shown in FIG. Whether or not (S551).

  If the pack restructuring unit 151 determines that the record cannot be extracted from the pool battery information table 123, the series of processing ends. If it is determined that the record can be extracted from the pool battery information table 123, all the records are extracted from the pool battery information table 123, and the set of records is set as a target pool (S552).

  Next, the pack rebuilding unit 151 extracts an unextracted Max performance value from the target pool (S553), and sets the counter value N of the extraction number counter to “1” (S554).

  Next, the pack restructuring unit 151 determines whether or not an unextracted next performance value closest to the Max performance value can be extracted from the target pool (S555). If the pack restructuring unit 151 determines that the next performance value that has not yet been extracted cannot be extracted from the target pool, the pack rebuilding unit 151 ends the series of processes. If it is determined that the next performance value that has not been extracted can be extracted from the target pool, the next performance value is extracted (S556).

  Next, it is determined whether or not the next performance value extracted in step 556 is equal to or higher than (Max-A) performance value (S557). When the next performance value is equal to or higher than (Max-A) performance value, the process proceeds to step 560 (FIG. 36), and when the next performance value is not equal to or higher than (Max-A) performance value, step 570 (FIG. Go to 37).

In step 560 (FIG. 36), the pack restructuring unit 151 adds “1” to the counter value N of the extraction number counter. Then, the pack restructuring unit 151 determines whether or not the counter value N of the extraction number counter is equal to the number of constituent batteries N ₀ grasped in Step 550 (S561). If it is determined that they are equal, it is determined that a battery pack satisfying the pack condition of the target pack has been constructed, and the process proceeds to step 562 (FIG. 23). If it is determined that they are not equal, the process returns to step 555. That is, here, the battery pack satisfying the pack condition of the target pack is constructed by repeatedly executing Steps 555, 556, 557, 560, and 561.

  If the pack rebuilding unit 151 determines in step 557 that the next performance value is not equal to or higher than the (Max-A) performance value, the pack rebuilding unit 151 first extracts the Max performance value from the target pool in step 570 (FIG. 37). The next performance value extracted in step 1 is set as the Max performance value. Subsequently, after extracting the Max performance value from the target pool, if the next performance value is extracted more than once, the next performance value after the second time is treated as unextracted (S571), and the process returns to Step 555.

  In other words, the processes in step 570 and step 571 are processes in which the Max performance value is shifted by one to the next performance value, and the processes after S555 are executed.

When the pack restructuring unit 151 determines in step 561 that the counter value N of the extraction number counter is equal to the number of constituent batteries N ₀ , the pack reconstruction unit 151 clears the counter value of the extraction number counter to “0” (S562).

In step 562, when the count value N of the extraction number counter is cleared to “0” by the pack restructuring unit 151, the buying price calculation unit 149 determines the median value for the N ₀ performance values extracted above. μ and dispersion value σ ² are calculated (S563).

Next, the purchase price calculation unit 149 corresponds to the battery type of the secondary battery incorporated in the newly reconstructed battery pack and the number of constituent batteries of this battery pack from the price function table 115 shown in FIG. The function f (μ, σ ² ) to be selected is selected (S564).

Then, the purchase price calculation unit 149 has N ₀ secondary batteries by substituting the median value μ and the variance value σ ² calculated in step 563 into the function f (μ, σ ² ). Find the selling price of the battery pack. Subsequently, the buying price calculation unit 149 multiplies the selling price by, for example, 1.2, adds a margin, and converts the selling price into a buying price (S565). That is, here, the purchase price of the reconstructed pack satisfying the pack condition of the target pack is obtained.

  When the purchase price of the reconstructed pack is obtained by the purchase price calculation unit 149, the pack restructuring unit 151 stores the information of the reconstructed pack in the purchase information table of the target pack (S566).

  Here, the purchase information table in the present modification will be described with reference to FIG.

  The purchase information table 148 is a table provided for each target pack ID, and relates to a target pack ID area 148a in which the target pack ID is stored and a target pack that can be purchased by the owner of the battery pack of the target pack ID. A purchase target pack information area 148c in which information is stored.

  The purchase information table 148 is created by the table creation / change unit 142 when the battery pack of the target pack ID is bought by the owner from the transaction management side, and at that time, the target pack ID area 148a is stored in the target pack. ID is stored. On the other hand, the purchase target pack information area 148c is updated each time the purchase price calculation and pack reconstruction process routines are executed.

  The purchase target pack information area 148c includes a purchase target pack ID area 118d in which the pack ID of the above-described purchase target pack is stored, a purchase price area 148i in which the purchase price of the purchase target pack is stored, and the purchase target pack. A performance value area 148k in which statistical values relating to the performance values of the secondary batteries incorporated in the battery are stored, and a production number area 148p in which the production number of the secondary battery incorporated in the target pack is stored. Yes.

  The performance value area 148k includes a minimum value area 148l in which the minimum performance value is stored among the performance values of the secondary battery incorporated in the purchase target pack, and the performance values of the secondary battery incorporated in the purchase target pack. A median value region 148m in which the median value is stored, and a variance value region 148n in which the variance value of each performance value of the secondary battery incorporated in the purchase target pack is stored.

  In step 566, the pack restructuring unit 151 creates a new record 148x in the purchase target pack information area 148c of the purchase information table 148. Next, the pack ID of the reconstructed pack is determined, and this pack ID is stored in the purchase target pack ID area 148d in the new record 148x.

  Next, the pack rebuilding unit 151 stores the buy price of the rebuilt pack obtained in S565 in the buy price area 148i of the new record 148x. Subsequently, the minimum performance value among the performance values of the secondary battery incorporated in the purchase target pack is stored in the minimum value area 148l of the new record 148x, and is incorporated in the purchase target pack in the median area 148m. The median value of each performance value of the secondary battery to be stored is stored, and the variance value of each performance value of the secondary battery to be incorporated in the purchase target pack is stored in the storage variance value area 148n. Then, the production number of the secondary battery incorporated in the purchase target pack is stored in the production number area 148p of the new record 148x.

  Above, the process of step 566 is complete | finished.

  Next, the pack rebuilding unit 151 determines whether or not an unextracted Max performance value can be extracted from the target pool (S567). If the unextracted Max performance value can be extracted, the process returns to Step 553 (FIG. 35), and if the unextracted Max performance value cannot be extracted, the series of processing ends.

  This completes the processing of the purchase price calculation and pack reconstruction routine.

  Next, a routine for executing the selling price calculation process will be described according to the flowchart shown in FIG.

First, the selling price calculation unit 145 calculates the median μ and the dispersion value σ ² regarding the performance values of all the secondary batteries incorporated in the target pack (S580).

Next, the selling price calculation unit 145 determines from the price function table 115 shown in FIG. 8 a function f (μ,) corresponding to the battery type of the secondary battery incorporated in the target pack and the number of constituent batteries of the battery pack. σ ² ) is selected (S581).

Then, the selling price calculation unit 145 obtains the selling price of the target pack by substituting the median value μ and the variance value σ ² calculated in step 580 for this function f (μ, σ ² ) (S582). This selling price is stored in the pack selling information table 147 (FIG. 39) (S583).

  Here, the selling information table 147 in this modification will be described with reference to FIG. The sale information table 147 has a target pack ID area 147a in which the pack ID of the battery pack for each user is stored, and a sell price area 147b in which the sale price of the battery pack is stored.

  In the target pack ID area 147a of the sale information table 147, when the battery pack is bought by the owner from the transaction management side, the pack ID of the battery pack is stored. The selling price area 147b is updated every time this selling price calculation routine is executed.

  This completes the processing in the selling price calculation routine.

  As described above, in this modified example, when a pack is reconstructed, a new battery pack is reconstructed using only a secondary battery that has already been pooled. The secondary battery in the battery pack does not depend on the performance value of the secondary battery incorporated in the target pack, and the degree of freedom in reconfiguring the battery pack can be increased.

  However, in the above embodiment, the battery pack to be purchased by the user is reconstructed with the secondary battery in the battery pack sold by another user. The battery packs to be purchased are the same in that they are constructed with pooled secondary batteries.

  Note that this modified example basically assumes the pack rebuilding process in the normal buying and selling process, but the pack rebuilding process in the auction buying and selling process is performed in the same manner as in this modified example. Reconstruction may be performed.

  Further, the pack restructuring process in the present invention may be executed in the process of calculating the selling price of the target pack as in the above embodiment, or the target to be purchased by the target pack owner as in this modification. You may make it perform in the process of calculating the purchase price of the battery pack used as a pack.

  Furthermore, in the above embodiment, the battery pack that is to be purchased by the user excluding the target pack owner is built in the pack rebuilding process. However, as in this modification, the target pack is in the pack rebuilding process. You may make it construct | assemble the battery pack used as a purchase object pack of an owner.

  By the way, in the said embodiment and the said modification, although the battery pack is reconfigure | reconstructed so that the performance value of the incorporated secondary battery may be settled in the range of one deviation A from Max performance value, deviation is There is no need for one, and a plurality of deviations may be used. In this case, after the battery pack rebuilding process is performed with one deviation, the battery pack rebuilding process is performed again with another deviation.

  As described above, when the battery pack rebuilding process is performed using a plurality of deviations, the combination of the secondary batteries in the battery pack is changed by the rebuilding process for each deviation. More options. However, when the battery pack rebuilding process is performed using a plurality of deviations, there is a possibility that the battery pack having the same combination of secondary batteries may be rebuilt by the rebuilding process for each deviation. For this reason, when the battery pack reconstruction process is completed with all deviations, it is preferable to remove such a battery pack when the combination of secondary batteries reconstructs the same battery pack.

"Auction Trading Variant"
In the above embodiment, the user sells the battery pack to the transaction management side by auction sale, and after the sale is established, the user places an auction on the battery pack including the secondary battery of the established battery pack. If the intention of selling the pack is displayed, the transaction management side may put the battery pack including the secondary battery of the battery pack into the auction without buying the battery pack.

  In this case, the transaction management side basically serves as a coordinator between a user who wants to sell the battery pack by auction and a user who wants to buy a battery pack including the secondary battery of the battery pack at the auction.

  Hereinafter, a specific example of the auction sales described above will be described with reference to FIGS.

  First, processing when accepting an auction sale from a user will be described.

  This process is started when the transaction management apparatus 100 receives from the user the pack ID of the battery pack owned by this user, the lowest successful bid price of this battery pack, and the auction sale of this battery pack. Is done.

  When the response processing unit 155 of the transaction management apparatus 100 receives the fact that the battery pack is being sold via the communication control unit 161, the battery pack ID of the battery pack, and the lowest successful bid price of the battery pack, In response to this, the battery pack delivery information and, for example, “I will inform you of the amount of money to be paid to you after the auction is established” are transmitted via the communication control unit 161. Note that in this modification, when the auction sale is accepted, the battery pack is not bought or sold as in the above embodiment. For this reason, at this stage, as in step 101 (FIG. 31) of the above embodiment, the seller is not notified that the sale has been completed. However, in this modification, in order to pool this battery pack, delivery information regarding this battery pack is notified to the seller.

  When the response processing unit 155 notifies the seller of delivery information and the like, the following processing is basically performed in the same manner as in the above embodiment. That is, the processing from step 102 to step 105 in FIG. 31 is executed.

  However, in this modification, in step 104, the buying and selling information creating unit 152, when the buying and selling information creating unit creates the auction buying information, the seller of the battery seller included in the auction buying target pack is included in the auction buying information. The ID, the number of batteries for the seller included in the auction purchase target pack, and the lowest successful bid price desired by the seller are included. Then, the buying and selling information creating unit 152 stores this auction buying information in the auction buying information table.

  Here, the auction purchase information table in the present modification will be described with reference to FIG.

  Similar to the auction purchase information table 122 (FIG. 13) in the above embodiment, the auction purchase information table 152 in the present modification example is a target pack ID area 122d, a battery type area 122f, a constituent battery number area 122g, a buy reference price area 122i, It has a performance value area 122k and a serial number area 122p. Furthermore, the auction purchase information table 152 in this modification example includes a determined purchase price area 152a in which the price determined by the target pack is determined by auction, and a seller in which information on all sellers of the batteries included in the target pack is stored. Information area 152b.

  The determined purchase price area 152a of the auction purchase information table 152 stores the price determined at the time when the auction related to the battery pack is established.

  The seller information area 152b of the auction purchase information table 152 stores the ID of the seller of the battery included in the target pack, the number of batteries for the seller in the target pack, and the lowest successful bid price desired by the seller. .

  In this modification, in step 104, the target pack ID area 122d, the battery type area 122f, the constituent battery number area 122g, the buy reference price area 122i, the performance value area 122k, the manufacturing number in the auction buying information table 152 described above are included. Data is stored in the area 122p and data is also stored in the seller information area 152b.

  Next, the auction buying process will be described with reference to the flowchart shown in FIG.

  Also in this modified example, when the auction related to the auction purchase target pack is started, the processes of steps 80 to 83 and 90 are executed as in the above embodiment. That is, a process for determining whether or not the bidding period relating to the auction purchase target pack has ended (S80), a process for determining whether or not an auction purchase has been accepted (S81), and a process for storing a company ID in the bid information table 125 ( S82), a process of determining whether or not there is a record in the bid information table 125 (S83), and a process of grasping the bidder ID of the highest bid price (S90).

  The bid management unit 145 determines in step 83 that there is a record in the bid information table 125. If the bid management unit 145 grasps the bidder ID of the highest bid price from the bid information table 125 in step 90, the bid price of the bidder ID, That is, it is determined whether or not the highest bid price is higher than the reference price, and whether or not the highest bid price is equal to or higher than the lowest bid price of the target pack (S111).

  Here, the reference price is a price stored in the buying reference price area 122i in the auction buying information table 152 shown in FIG. Further, the target pack lowest winning bid price is a price based on the lowest winning bid price designated by the seller of a plurality of batteries included in the auction buying target pack.

  The auction purchase target pack basically includes secondary batteries in the battery packs of a plurality of sellers. Furthermore, each seller of the secondary batteries included in the auction purchase target pack individually designates the lowest successful bid price for the battery pack that he / she owns. Therefore, here, the lowest successful bid price of the auction purchase target pack is determined based on the lowest successful bid price designated by each seller.

Specifically, as shown in the following (Equation 1), a value obtained by summing the lowest successful bid prices for the sellers of the batteries in the target pack for each seller is set as the lowest successful bid price of the target pack.
Minimum winning bid for the target pack = Σ (Minimum winning bid for the seller of the batteries in the target pack)
・ ・ ・ ・ ・ ・ (Equation 1)

Here, the lowest successful bid price for the seller of the battery in the target pack is a value using the following (Equation 2).
Minimum contract price for seller of batteries in target pack = Minimum contract price specified by seller
× (Number of batteries in target pack / number of batteries in seller pack)
× (number of seller's batteries in target pack / number of constituent batteries in target pack)
・ ・ ・ ・ ・ ・ (Equation 2)

  In the above (Equation 2), the lowest bid price specified by the seller is acquired from the seller information area 152b of the auction purchase information table 152 (FIG. 43). In addition, in (Equation 2), (number of constituent batteries of the target pack / number of constituent batteries of the seller pack) is a term for converting the lowest bid price specified by the seller into the number of constituent batteries of the target pack ( The number of seller's batteries in the target pack / the number of constituent batteries of the target pack) is a term for converting the minimum contract price designated by the seller into the proportion of the constituent batteries of the seller in the target pack.

  If the bid management unit 145 determines in step 111 that the highest bid price is higher than the reference price and the highest bid price is equal to or higher than the lowest successful bid price of the target pack, the bid management unit 145 relates to the target pack in the auction purchase information table 152 (FIG. 43). The highest bid price is stored in the determined purchase price area 152a (S112).

  Hereinafter, similarly to the embodiment described above, notification processing of successful bids to successful bidders (S91, 92), change processing of successful bidder records in pack management table 111 (S93), and purchase target pack IDs. The creation process (S94) of the pack condition information table 112 and the like, and the deletion process (S95) of the bid information table 125 and the like are executed.

  However, in step 95, the table creation / change unit 142 deletes the bid information table 125 related to the auction purchase target pack as soon as step 94 is completed, and also from the pool battery information table 123, as in the above embodiment. Although all records including the production number of the secondary battery included in the target pack are deleted, the deletion of the record including the manufacturing number of the secondary battery included in the auction purchase target pack from the auction purchase information table 122 is deleted. Is slightly different from the above embodiment.

  In this modification, the record of this auction purchase target pack is deleted one week after the auction is established, out of all records including the production number of the secondary battery included in the auction purchase target pack from the auction purchase information table 122, Delete other records immediately.

  Here, the reason for this will be described below.

  As described above, the auction purchase target pack basically includes secondary batteries in a plurality of seller's battery packs. In addition, a plurality of secondary batteries in each seller's battery pack may be distributed among a plurality of auction purchase target packs. For this reason, even if the auction purchase price for a certain auction purchase target pack is determined, the deposit amount (sell price) for some sellers of secondary batteries in this target pack is not determined. The deposit amount (sell price) to the seller is determined only after the auction purchase price for all the auction purchase target packs including any secondary battery in the seller's battery pack is determined.

  That is, in order to determine the deposit amount (sell price) to the seller, each auction purchase target is determined until the auction purchase price for all the auction purchase target packs including any secondary battery in the seller's battery pack is determined. Auction buying information on packs must not be deleted.

  In addition, as described above, the auction purchase target pack basically includes the secondary batteries in the battery packs of a plurality of sellers. Even if the information deletion condition is satisfied, the purchase information of the auction purchase target pack must not be deleted if the other seller does not satisfy the purchase information deletion condition of the auction purchase target pack.

  On the other hand, in this modification, if the bidding period of any auction is, for example, one week, the secondary batteries in the battery packs of all sellers related to the auction purchase target pack for which the auction has been established are also used in this auction. The auction result is always known one week after the auction of the target pack is completed.

  Therefore, in this modification, in step 95, the records of the auction purchase target packs for which the auction has been established are deleted from the auction purchase information table 152 one week after the auction has been established.

  Returning again to the description based on FIG.

  If the bid management unit 145 determines in step 83 that there is no table in the bid information table 125, then in step 111, the highest bid price is not higher than the reference price, or the highest bid price is the lowest bid of the target pack. If it is determined that the price is not higher than the price, it is determined whether or not the reference price is equal to or higher than the lowest successful bid price of the target pack (S113).

  If the bid management unit 145 determines that the reference price is equal to or higher than the minimum winning bid price of the target pack, it determines that the transaction management side will purchase the target pack and proceeds to step 114, and determines that the reference price is not higher than the lowest winning bid price of the target pack. Then, the transaction management side also determines that the target pack cannot be purchased and ends a series of processes.

  In step 114, the bid management unit 145 stores the reference price in the determined purchase price area 152a related to the target pack in the auction purchase information table 152 (FIG. 43). In other words, the transaction management side purchases the auction purchase target pack at the reference price.

  When the reference price is stored in the determined purchase price area 152a of the auction purchase information table 152, the table creation / change unit 142 deletes the bid information table 125 related to the auction purchase target pack as in the process in step 95. Then, the record including the manufacturing number of the secondary battery included in the auction purchase target pack is deleted from the auction purchase information table 122 (S115), and the series of processes is terminated. However, in this case as well, in the same manner as the processing in step 95, the record of the auction purchase target pack is selected from all records including the manufacturing number of the secondary battery included in the auction purchase target pack from the auction purchase information table 122. It will be deleted one week after the auction is completed, and other records will be deleted immediately.

  In this step 115, unlike the step 95, all records including the manufacturing number of the secondary battery included in the auction purchase target pack are not deleted from the pool battery information table 123. This is because the transaction management side needs to pool the auction purchase target pack and store it.

  Next, with reference to FIG. 42, a description will be given of the amount of money (sale price) determination processing to the seller of the battery pack including the secondary battery incorporated in the auction purchase target pack.

  The selling price calculation unit 145 monitors whether or not the price is stored in the determined buying price area 152a of the auction buying information table 152 shown in FIG. 45 (S120).

  When the selling price calculation unit 145 determines that the price is stored in the determined buying price area 152 a of the auction buying information table 152, the selling price calculation unit 145 refers to the seller information area 152 b of the auction buying information table 152 and uses the auction buying information table 152 to set the price. Is stored, that is, the seller ID of the target pack whose auction price is determined is determined. Then, it is determined whether or not prices are stored in the determined purchase price area 152a for all records including the seller ID (S121).

  If the selling price calculation unit 145 determines that no price is stored in the determined buying price area 152a for all the records including the seller ID, the series of processing ends. If the selling price calculation unit 145 determines that prices are stored in the determined buying price area 152a for all records including the seller ID, the selling price calculation unit 145 obtains the price for the seller for each record (S122).

  The selling price calculation unit 145 pays attention to one record among all records including the seller ID, and the auction buying price in which the price is stored in the determined buying price area 152a of this record, and the seller information area of this record The number of batteries for the seller stored in 152b is grasped, and the auction buying price for the seller is obtained by multiplying the auction buying price by (the number of batteries for the seller / the number of constituent batteries of the target pack). The selling price calculation unit 145 performs the above processing for all records including the seller ID.

  Next, the selling price calculation unit 145 calculates the buying price for the battery pack of the seller by summing the prices for the seller for each record obtained in step 122, and multiplies the buying price by, for example, 0.8. The buying price is converted into a selling price (S123).

  When the selling price regarding the battery pack of the seller is obtained, the response processing unit 155 causes the communication control unit 161 to transmit the fact that the auction has been established and the amount of money received to the seller, that is, the selling price, to the seller (S124). .

  The payment amount (sale price) determination process for the seller is thus completed.

Although the above modification is an auction by a user who desires to purchase a battery pack, in the present invention, an auction by a user who desires to sell a battery pack may be performed.
"Pool variants"
In the above embodiment, only the secondary battery in the battery pack purchased from a general user is a pool battery, but a new secondary battery may be a pool battery.

  In this case, in order to make this secondary battery available for the battery pack restructuring process, a registration application regarding a new secondary battery is received from a vendor 6 and the like, and information regarding this secondary battery is stored in the pool battery information table. 123. Furthermore, in step 520 (FIG. 24) of the above-described embodiment, a) a performance value that is a condition for extracting the performance value, a) being equal to or less than the Max performance value in the secondary battery of the target pack, b) a performance value closest to Max. The condition a) is deleted from the fact that it is present and c) that it has not been extracted. Furthermore, in step 521 (FIG. 24) of the above-described embodiment, extraction performance value ≦ (Max + B) is added as a condition for determining whether or not the repacking condition is satisfied. “B” is a predetermined value. Further, this additional condition is that if the performance value of the new secondary battery is extracted in step 520, the performance of the new secondary battery is compared with the Max performance value in the secondary battery of the target pack. When the value is larger than B, it is a condition for eliminating this performance value.

"Other"
In the above embodiment, the purchase price of the battery pack is calculated in two methods, that is, a method for obtaining the performance value by substituting the median value and variance value of each performance value of the secondary battery incorporated in the battery pack into a function. However, the present invention is not limited to this, and the purchase price of the battery pack may be obtained by other methods.

  For example, the purchase price may be determined according to the demand or supply. For example, when secondary batteries within a certain range of performance values are pooled in a quantity greater than or equal to a predetermined value, the purchase price of the battery pack including the secondary battery may be lowered according to this quantity.

  In the above embodiment, the pool battery is managed separately for normal use and for auction, but the pool battery need not be managed separately for normal use and auction use.
