Description

Technical Field

[0001] The present invention relates to a system for reusing used secondary batteries. Background Art

[0002] Conventionally, a system has been proposed that can specify a suitable secondary battery corresponding to the reuse party when reusing used secondary batteries in other fields (see Patent Document 1).

[0005] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2018-50457 Summary of the Invention

[0006] Problems to be Solved by the Invention

[0007] According to this prior art, based on the operation history information of the storage battery, the remaining value of the storage battery is calculated, and based on the remaining value information, the storage batteries with remaining value are screened, and the remaining value satisfies the content of the demand information that the storage battery required by the system of the reuse party should satisfy.

[0008] However, the transportation cost from the storage place of the used secondary battery to the utilization place is included in the total payment amount of the purchaser of the used secondary battery. Even if the used secondary battery can be prepared at a low cost, when the transportation cost is very high, the total payment amount will be very high, so the user will hesitate to purchase the used secondary battery.

[0009] In the prior art, since the transportation cost from the storage place of the used secondary battery to the utilization place is not considered, the total payment amount that the user should pay when purchasing the used secondary battery may be very high, resulting in the difficulty in popularizing the used secondary battery.

[0010] Therefore, an object of the present invention is to provide a system that can reduce the transportation cost of used secondary batteries and sell used secondary batteries at a low price.

[0011] Means for Solving the Problems

[0012] The used secondary battery reuse system of the present invention,

[0013] supports the reuse of used secondary batteries used as secondary batteries for vehicle drive, and is characterized by comprising:

[0014] A storage unit that stores location information of multiple trade-in facilities for trading in the vehicle equipped with the secondary battery, first information that associates the uses of the used secondary battery with the degradation states required for use in those uses by potential buyers, and second information that associates the uses with the prices at which the used secondary battery is sold for use in those uses;

[0015] A desired purchase information receiving unit that receives desired purchase information of the used secondary battery and stores it in the storage unit. The desired purchase information comes from a potential buyer who desires to purchase the used secondary battery and includes the use of the used secondary battery by the potential buyer and location information of the delivery location;

[0016] A desired trade-in information receiving unit that receives desired trade-in information. The desired trade-in information comes from a potential trade-in customer who desires to trade in the vehicle and includes information indicating the degradation state of the secondary battery mounted on the vehicle;

[0017] An extraction unit that refers to the first information, identifies the degradation state associated with the use of the used secondary battery included in the desired purchase information by the potential buyer, and extracts the desired purchase information in which the identified degradation state matches the degradation state included in the desired trade-in information;

[0018] A sales price determination unit that refers to the second information, identifies the price associated with the use of the used secondary battery included in the extracted desired purchase information by the potential buyer, and determines the identified price as the sales price of the secondary battery for trade-in charged to the potential buyer;

[0019] A transportation cost estimation unit that calculates the distances from the multiple trade-in facilities to the delivery location based on the location information of the delivery location included in the extracted desired purchase information and the location information of the multiple trade-in facilities, and estimates the transportation costs from each trade-in facility of the secondary battery for trade-in to the delivery location based on the calculated distances; and

[0020] A trade-in price determination unit that determines the amount obtained by subtracting a prescribed profit amount from the sales price of the secondary battery for trade-in as the trade-in base amount, and determines the amount obtained by subtracting the transportation cost from the trade-in base amount as the trade-in price of the secondary battery for trade-in at each trade-in facility.

[0021] In the used secondary battery reuse system of the present invention, through the extraction unit, the degradation state associated with the use of the used secondary battery by the prospective purchaser is identified, and the prospective purchase information in which the identified degradation state matches the degradation state included in the trade-in information is extracted. Then, through the selling price determination unit, the price associated with the use of the used secondary battery by the prospective purchaser is identified, and the identified price is determined as the selling price of the secondary battery for trade-in charged to the prospective purchaser.

[0022] In addition, through the transportation cost estimation unit, based on the location information of the delivery location included in the prospective purchase information and the location information of multiple trade-in facilities, the distances from the multiple trade-in facilities to the delivery location are calculated respectively, and based on the calculated distances, the transportation costs from each trade-in facility of the secondary battery for trade-in to the delivery location are estimated.

[0023] In addition, through the trade-in price determination unit, based on the amount obtained by subtracting the transportation cost from the selling price of the secondary battery for trade-in, the trade-in price of the secondary battery for trade-in in each trade-in facility is determined.

[0024] Thus, the trade-in price of the secondary battery is determined considering the degradation state of the secondary battery for trade-in and the transportation cost, and the transportation cost is based on the use of the prospective purchaser, the location of the delivery location, and the location of multiple trade-in facilities included in the prospective purchase information. Therefore, the trade-in price is an appropriate amount that conforms to the actual situation of the secondary battery.

[0025] In this way, according to the used secondary battery reuse system of the present invention, the transportation cost of the used secondary battery can be reduced and the used secondary battery can be sold at a low price.

[0026] In the used secondary battery reuse system of the present invention,

[0027] Preferably, it is provided with a trade-in facility information output unit that outputs information indicating the trade-in price in each trade-in facility determined by the trade-in price determination unit and the location of each trade-in facility to the prospective trade-in person.

[0028] In the used secondary battery reuse system of the present invention, through the trade-in facility information output unit, information indicating the trade-in price in each trade-in facility and the location of each trade-in facility is output to the prospective trade-in person.

[0029] Thus, the prospective trade-in person knows in advance the trade-in price of each trade-in facility, so that they can fully study at which trade-in facility to conduct the trade-in, thereby enhancing the sense of conviction in the trade-in price.

[0030] Thus, the used secondary battery reuse system according to the present invention can enhance the trust of those who wish to trade in their used batteries in the trade-in price, reduce the transportation cost of used secondary batteries, and sell used secondary batteries at a low price.

[0031] In the used secondary battery reuse system of the present invention,

[0032] Preferably, the trade-in facility information output unit is configured to display the information indicating the location of the trade-in facility with the highest trade-in price and the display of the trade-in price in that trade-in facility differently from the display of the information about other trade-in facilities.

[0033] In the used secondary battery reuse system of the present invention, when the information indicating the trade-in facility with the highest trade-in price and the trade-in price in that trade-in facility are output to those who wish to trade in their used batteries through the trade-in facility information output unit, a display different from the display of the information about other trade-in facilities is performed.

[0034] Thereby, those who wish to trade in their used batteries can clearly know where the trade-in facility with the highest trade-in price is, so that the efficiency of researching at which trade-in facility to conduct the trade-in can be improved.

[0035] Thus, the used secondary battery reuse system according to the present invention can, while improving the efficiency of researching at which trade-in facility to conduct the trade-in by those who wish to trade in their used batteries, reduce the transportation cost of used secondary batteries and sell used secondary batteries at a low price.

[0036] In the used secondary battery reuse system of the present invention,

[0037] Preferably, it includes: a trade-in information processing unit that stores information related to the secondary battery to be traded in in the storage unit;

[0038] a reservation information receiving unit that receives information indicating a reservation to purchase the secondary battery to be traded in from the prospective purchaser and stores it in the storage unit; and

[0039] a reservation information output unit that outputs the information stored in the storage unit indicating a reservation to purchase the secondary battery to be traded in.

[0040] In the used secondary battery reuse system of the present invention, through the reservation information receiving unit, information indicating a reservation to purchase the secondary battery to be traded in is received from the prospective purchaser and stored in the storage unit.

[0041] In addition, through the reservation information output unit, the stored information indicating a reservation to purchase the secondary battery to be traded in is output.

[0042] Accordingly, those who conduct the trade-in of secondary batteries can easily know which used secondary batteries have been reserved, and thus can efficiently manage the inventory of used secondary batteries.

[0043] In this way, the used secondary battery reuse system according to the present invention can reduce the transportation cost of used secondary batteries, efficiently manage the inventory of used secondary batteries, and sell used secondary batteries at a low price.

[0044] In the used secondary battery reuse system of the present invention,

[0045] Preferably, the desired purchase information receiving unit is configured to receive desired purchase information including information specifying the transportation method of the used secondary battery from the desired purchaser to the delivery location.

[0046] The transportation cost estimating unit is configured to estimate the transportation cost based on information corresponding to the distances from the respective trade-in facilities to the delivery location and including the occupancy time of the vehicle used for transportation.

[0047] Depending on the land conditions of the delivery location, etc., for example, there may be restrictions on the size of the vehicles that can be used for transportation and the heavy machinery that can be used for on-site loading. Correspondingly, the transportation cost may also vary.

[0048] In the used secondary battery reuse system of the present invention, the desired purchase information receiving unit receives desired purchase information including information specifying the transportation method of the used secondary battery to the delivery location. Then, the transportation cost estimating unit estimates the transportation cost based on information corresponding to the distances from the respective trade-in facilities to the delivery location and including the occupancy time of the vehicle used for transportation.

[0049] Accordingly, the transportation cost is estimated taking into account the transportation method of the used secondary battery, so that a more realistic transportation cost can be estimated.

[0050] In this way, the used secondary battery reuse system according to the present invention can reduce the transportation cost of used secondary batteries and sell used secondary batteries at a low price and a realistic amount.

[0051] In the used secondary battery reuse system of the present invention,

[0052] Preferably, the transportation cost estimating unit is configured to calculate the distances from the respective trade-in facilities of the trade-in secondary batteries to the delivery location, and estimate the transportation cost from the respective trade-in facilities of the trade-in secondary batteries to the delivery location based on the calculated distances.

[0053] In the used secondary battery reuse system according to the present invention, through the transportation cost estimation unit, based on the distance from each trade-in facility of the trade-in secondary battery to the delivery location, the transportation cost from each trade-in facility of the trade-in secondary battery to the delivery location is estimated.

[0054] Thus, by performing the transportation cost estimation process based on specific information such as distance, the estimation accuracy of the transportation cost can be improved.

[0055] In this way, the used secondary battery reuse system according to the present invention can, while improving the estimation accuracy of the transportation cost, reduce the transportation cost of the used secondary battery and sell the used secondary battery at a low price.

[0056] In the used secondary battery reuse system of the present invention,

[0057] Preferably, the transportation cost estimation unit is configured to exclude from the estimation target of the transportation cost each trade-in facility whose distance from each trade-in facility of the trade-in secondary battery to the delivery location is equal to or greater than a specified distance.

[0058] If a secondary battery is traded in at a trade-in facility that is too far from the delivery location, the transportation cost at the time of delivery will become very high. Therefore, it is not realistic to trade in a secondary battery at a trade-in facility that is too far from the delivery location.

[0059] In the used secondary battery reuse system of the present invention, through the transportation cost estimation unit, the distance from each trade-in facility of the trade-in secondary battery to the delivery location is calculated, and each trade-in facility whose calculated distance is equal to or greater than a specified value is excluded from the estimation target of the transportation cost.

[0060] Thus, from the perspective of the transportation cost at the time of delivery, when trading in at a trade-in facility, a realistic trade-in facility is selected for the transportation cost estimation process, so that the transportation cost can be estimated efficiently.

[0061] In this way, the used secondary battery reuse system according to the present invention can, while improving the efficiency of the transportation cost estimation, reduce the transportation cost of the used secondary battery and sell the used secondary battery at a low price.

[0062] In the used secondary battery reuse system of the present invention,

[0063] Preferably, the desired purchase information receiving unit is configured to receive desired purchase information including information specifying the desired delivery period of the used secondary battery to the delivery location.

[0064] The used secondary battery reuse system further includes: a required degradation state determination unit that estimates the progress of degradation until the used secondary battery is delivered to the prospective purchaser based on the information specifying the desired delivery time of the used secondary battery included in the prospective purchase information, and adds the estimated progress of degradation to the degradation state corresponding to the use of the used secondary battery included in the prospective purchase information identified by the extraction unit to determine the degradation state required for the trade-in of the trade-in secondary battery.

[0065] The extraction unit is configured to extract the prospective purchase information in which the degradation state required for the trade-in of the trade-in secondary battery matches the degradation state included in the prospective trade-in information.

[0066] If the time from the trade-in of the used secondary battery to its delivery to the prospective purchaser is long, the degradation state of the used secondary battery during the storage period may continue to progress. Therefore, at the time of trade-in, it is necessary to consider the progress of degradation during the storage period to determine the trade-in price.

[0067] In the used secondary battery reuse system of the present invention, the required degradation state determination unit estimates the progress of degradation until the used secondary battery is delivered to the prospective purchaser based on the information specifying the desired delivery time of the used secondary battery included in the prospective purchase information.

[0068] In addition, the required degradation state determination unit adds the estimated progress of degradation to the degradation state corresponding to the use of the used secondary battery included in the prospective purchase information identified by the extraction unit to determine the degradation state required for the trade-in of the trade-in secondary battery.

[0069] Then, the extraction unit extracts the prospective purchase information in which the degradation state required for the trade-in of the trade-in secondary battery matches the degradation state included in the prospective trade-in information.

[0070] Thereby, the prospective purchase information is extracted while also considering the progress of degradation during the storage period to determine the trade-in price for the extracted prospective purchase information, so that a more realistic trade-in price can be determined.

[0071] In this way, according to the used secondary battery reuse system of the present invention, the transportation cost of the used secondary battery can be reduced and the used secondary battery can be sold at a low and realistic price.

[0082] The used secondary battery reuse system of the present embodiment will be described with reference to the accompanying drawings. In addition, for the same structure, the same reference numerals may be used and the description may be omitted.

[0083] The used secondary battery reuse system of the present embodiment is a system that supports the reuse of used secondary batteries used for vehicle driving. For example, it includes a prospective purchaser device 10, a prospective trade-in device 30, and a server 50. The prospective purchaser device 10 and the server 50, and the prospective trade-in device 30 and the server 50 are communicably connected to each other through a communication network 90. In addition, in Figure 1 only one prospective purchaser device 10 and one prospective trade-in device 30 are shown respectively, but the number of prospective purchaser devices 10 and prospective trade-in devices 30 operating at the same time can be multiple or one.

[0084] The prospective purchaser device 10 is a device such as a smartphone, a tablet computer, or a personal computer used by the prospective purchaser B when operating the used secondary battery recycling system.

[0085] The prospective purchaser device 10 has, for example, a prospective purchaser device control unit 110, a prospective purchaser device storage unit 130, a prospective purchaser device input unit 150, and a prospective purchaser device output unit 170.

[0086] The prospective purchaser device control unit 110 is composed of an arithmetic processing device such as a CPU (Central Processing Unit), a memory, and I / O (Input / Output) devices.

[0087] The prospective purchaser device control unit 110 functions as, for example, a prospective purchase information receiving unit 111 or further as a reservation information receiving unit 113 by reading and executing a prescribed program.

[0088] The prospective purchase information receiving unit 111 receives the prospective purchase information of the used secondary battery from the prospective purchaser B who wishes to purchase the used secondary battery, which includes the use of the used secondary battery and the location information of the delivery place, and stores it in the server storage unit 530.

[0089] Alternatively, further, the prospective purchase information receiving unit 111 is configured to receive the prospective purchase information including information specifying the transportation method and / or the desired delivery time of the used secondary battery to the delivery place and store it in the server storage unit 530.

[0090] The reservation information receiving unit 113 receives the information indicating the reservation purchase of the trade-in secondary battery RB from the prospective purchaser B and stores it in the server storage unit 530.

[0091] The prospective purchaser device storage unit 130 is composed of storage devices such as a ROM (Read Only Memory), a RAM (Random Access Memory), and an HDD (Hard Disk Drive), for example. The prospective purchaser device storage unit 130 stores the information required for the operation of the prospective purchaser device 10.

[0092] The prospective purchaser device input unit 150 is, for example, a keyboard, a touch panel, a mouse, or other pointing devices that receive the input made by the prospective purchaser B. The prospective purchaser device output unit 170 is, for example, a display that outputs information to the prospective purchaser B.

[0093] The device 30 for the trade-in applicant is a device such as a smartphone, a tablet computer, or a personal computer that the trade-in applicant S uses when operating the used secondary battery reuse system.

[0094] The device 30 for the trade-in applicant, for example, includes a control unit 310 for the trade-in applicant, a storage unit 330 for the trade-in applicant, an input unit 350 for the trade-in applicant, and an output unit 370 for the trade-in applicant.

[0095] The control unit 310 for the trade-in applicant functions as, for example, a trade-in information receiving unit 311 and a trade-in facility information output unit 313 by reading and executing a prescribed program.

[0096] The trade-in information receiving unit 311 receives trade-in information from the trade-in applicant S who wishes to trade in the vehicle M, and the trade-in information includes information indicating the deterioration state of the secondary battery RB mounted on the vehicle M. In addition, the deterioration state of the secondary battery RB is, for example, the SOH (State Of Health) of the secondary battery RB.

[0097] The trade-in facility information output unit 313 outputs, via the output unit 370 for the trade-in applicant, information indicating the trade-in price in each trade-in facility determined by the trade-in price determination unit 517 and the location of each trade-in facility to the trade-in applicant S.

[0098] The storage unit 330 for the trade-in applicant is composed of storage devices such as a ROM and an HDD, and stores information required for the operation of the device 30 for the trade-in applicant.

[0099] The input unit 350 for the trade-in applicant is, for example, a keyboard, a touch panel, a mouse, or other pointing devices that receive an input made by the trade-in applicant S. Alternatively, for example, the input unit 350 for the trade-in applicant may also be a camera, a terminal, and a sensor that directly obtain the deterioration state (SOH) of the secondary battery RB mounted on the vehicle M via the vehicle M or from the secondary battery RB.

[0100] The output unit 370 for the trade-in applicant is, for example, a display that outputs information to the trade-in applicant S.

[0101] The server 50 is, for example, a computer having a server control unit 510, a server storage unit 530, and a server output unit 570. The server 50 may be a single unit or may be composed of multiple devices, and may also be provided in each trade-in facility.

[0102] The server control unit 510 functions as, for example, an extraction unit 511, a selling price determination unit 513, a transportation cost estimation unit 515, a trade-in price determination unit 517, or further as a trade-in information processing unit 519, a reservation information output unit 521, and a required deterioration state determination unit 523 by reading and executing a prescribed program.

[0103] The extraction unit 511 extracts the desired purchase information in which the use of the used secondary battery matches the deterioration state included in the trade-in desired information from the server storage unit 530.

[0104] The selling price determination unit 513 determines the selling price of the trade-in secondary battery RB to be charged to the desired purchaser B according to the use of the used secondary battery related to the desired purchase information extracted by the extraction unit 511.

[0105] The transportation cost estimation unit 515 estimates the transportation cost from each trade-in facility of the trade-in secondary battery to the delivery location based on the location information of the delivery location included in the extracted desired purchase information and the location information of a plurality of trade-in facilities.

[0106] Alternatively, further, the transportation cost estimation unit 515 is configured to estimate the transportation cost based on the information specifying the transportation method of the used secondary battery.

[0107] The trade-in price determination unit 517 determines the trade-in price of the trade-in secondary battery in each of the above trade-in facilities based on the above selling price and the above transportation cost of the above trade-in secondary battery.

[0108] The trade-in information processing unit 519 stores the information related to the trade-in secondary battery RB in the server storage unit 530.

[0109] The reservation information output unit 521 outputs the information indicating the reservation to purchase the trade-in secondary battery RB stored in the storage unit 530 by the trade-in information processing unit 519 to the person in charge of the trade-in facility via the server output unit 570.

[0110] The required deterioration state determination unit 523 determines the required deterioration state when trading in the trade-in secondary battery RB based on the use of the used secondary battery included in the trade-in desired information and the information specifying the desired delivery time.

[0111] In addition to storing the location information of a plurality of trade-in facilities for the trade-in of vehicles equipped with secondary batteries, the server storage unit 530 also stores information required for processing performed by the server control unit 510. That is, in the present embodiment, the server storage unit 530 functions as a storage unit that stores the location information of a plurality of trade-in facilities that perform trade-ins on vehicles M equipped with the secondary battery RB for driving.

[0112] In the server storage unit 530, for example, a trade-in facility DB (Data Base) 531, a wish-to-purchase DB 533, and a used secondary battery DB 535 are stored.

[0113] For example, as Figure 2A shown, the trade-in facility DB 531 stores latitude and longitude as the location information of a plurality of trade-in facilities that perform trade-ins on the vehicle M equipped with the secondary battery RB.

[0114] The wish-to-purchase DB 533 is a DB that stores wish-to-purchase information. For example, as Figure 2B shown, it stores a wish-to-purchase ID, the name of the wish-to-purchaser, the use of the used secondary battery, the desired charge capacity, the location information (latitude and longitude) of the delivery place, the transportation method, and information indicating the desired delivery period.

[0115] The used secondary battery DB 535 is a DB that stores information related to the secondary battery for trade-in. For example, as Figure 2C shown, it stores a used secondary battery ID, the deterioration state (SOH), and the charge capacity information. In addition, if the used secondary battery RB has been reserved, the wish-to-purchase ID of the wish-to-purchase information that becomes the object is stored as information indicating this situation.

[0116] The server output unit 570 is, for example, a display that outputs information to the person in charge of the trade-in facility.

[0117] Next, with reference to Figure 3A 、 Figure 3B the processing content of the used secondary battery reuse system of the present embodiment will be described.

[0118] <Summary of Processing>

[0119] First, with reference to Figure 3A a series of processing until the information of the trade-in facility with the highest trade-in price and the trade-in price in the trade-in facility are output to the person S wishing to trade in will be described.

[0120] A series of processes of the used secondary battery reuse system according to this embodiment are executed at any time, for example, according to the operation of the prospective purchaser B using the prospective purchaser device 10.

[0121] When starting the process, first, the prospective purchaser information receiving unit 111 of the prospective purchaser device 10 receives the prospective purchase information of the used secondary battery from the prospective purchaser B who wishes to purchase the used secondary battery, which includes the use of the used secondary battery and the location information of the delivery place, and sends it to the server 50 ( Figure 3A / S10).

[0122] In addition, at this time, the prospective purchaser information receiving unit 111 may also receive, as needed, the prospective purchase information that includes information specifying the transportation method of the used secondary battery to the delivery place and / or information specifying the desired delivery time of the used secondary battery to the delivery place.

[0123] Then, the server storage unit 530 stores the prospective purchase information received from the prospective purchaser device 10 ( Figure 3A / S20).

[0124] After that, according to the operation of the trade-in customer S using the trade-in customer device 30, the trade-in information receiving unit 311 receives the trade-in information and sends it to the server 50. The trade-in information comes from the trade-in customer S who wishes to trade in the vehicle M and includes information indicating the deterioration state (SOH) of the secondary battery RB mounted on the vehicle M ( Figure 3A / S30).

[0125] In addition, as a method for receiving the deterioration state (SOH), various methods can be adopted. For example, when the vehicle M itself has a function of displaying the SOH of the secondary battery, the trade-in customer can also use the trade-in customer device input unit 350 of the trade-in customer device 30 to input the SOH displayed on the vehicle M through manual input or shooting. Or, when the trade-in customer device input unit 350 is a terminal and sensor that directly obtains the deterioration state (SOH) of the secondary battery RB mounted on the vehicle M from the vehicle M or the secondary battery RB, they can also be used to obtain and receive the deterioration state (SOH) of the secondary battery RB.

[0126] Next, the extraction unit 511 of the server 50 receives the trade-in information ( Figure 3A / S40), and extracts the prospective purchase information in which the use of the used secondary battery matches the deterioration state included in the received trade-in information ( Figure 3A / S50).

[0127] More specifically, the extraction unit 511 refers to the desired purchase DB 533 in the server storage unit 530 to obtain the desired purchase information, and for example, refers to Figure 4 a table storing the uses of used secondary batteries and the deterioration states corresponding to these uses as shown, to identify the deterioration states corresponding to the uses included in each desired purchase information.

[0128] Then, the extraction unit 511 extracts the deterioration states corresponding to the uses included in each desired purchase information and the desired purchase information that matches the deterioration states included in the trade-in information.

[0129] In addition, before performing this extraction process, the deterioration state determination unit 523 may also be configured to determine the deterioration state required when trading in the secondary battery RB for a new one based on the use of the used secondary battery included in the desired purchase information and the information specifying the desired delivery time. In this case, the extraction unit 511 extracts the desired purchase information in which the deterioration state required when trading in the secondary battery RB for a new one matches the deterioration states included in the trade-in information.

[0130] That is, for example, when the deterioration state corresponding to the use of the used secondary battery included in the desired purchase information is 80% and it deteriorates by 5% until the estimated desired delivery time included in the desired purchase information, the deterioration state determination unit 523 determines that the deterioration state required when trading in the secondary battery RB for a new one is 85%. In this case, if the deterioration state included in the trade-in information is 85% or more, the extraction unit 511 extracts this desired purchase information as the desired purchase information that matches the deterioration states included in the trade-in information.

[0131] Next, the selling price determination unit 513 determines the selling price of the secondary battery RB to be traded in to the desired purchaser B according to the use of the used secondary battery related to the desired purchase information extracted by the extraction unit 511 ( Figure 3A / S60).

[0132] More specifically, the selling price determination unit 513, for example, refers to Figure 4 a table storing the uses of used secondary batteries and the selling prices corresponding to these uses as shown, to obtain the selling prices corresponding to the uses included in each desired purchase information, and determines the obtained selling price as the selling price of the secondary battery RB to be traded in to the desired purchaser B.

[0133] Next, the transportation cost estimation unit 515 estimates the transportation cost from each trade-in facility of the secondary battery RB to be traded in to the delivery location based on the location information of the delivery location included in the desired purchase information extracted by the extraction unit 511 and the location information of multiple trade-in facilities ( Figure 3A / S70).

[0134] More specifically, the transportation cost estimation unit 515 respectively determines the transportation routes of the used secondary battery RB for multiple trade-in facilities based on the location information of the delivery location and the location information of multiple trade-in facilities by using, for example, a well-known method.

[0135] Moreover, the transportation cost estimation unit 515 calculates, for example, the distance from each trade-in facility of the secondary battery RB to be traded in to the delivery location based on the transportation route. In addition, the transportation cost estimation unit 515 calculates the transportation cost of the used battery RB and the cost of on-site installation, etc. from each trade-in facility to the delivery location by considering the occupied time of the vehicle used for transportation and the equipment used for on-site installation, the number of required personnel and the required time, and other factors that change the transportation cost based on the calculated distance.

[0136] In addition, at this time, the transportation cost estimation unit 515 may also exclude from the estimation target of the above transportation cost those trade-in facilities whose distance from each trade-in facility to the delivery location is equal to or greater than a specified distance.

[0137] Then, the trade-in price determination unit 517 determines the trade-in price of the secondary battery RB to be traded in at each trade-in facility based on the selling price of the secondary battery to be traded in and the transportation cost ( Figure 3A / S80).

[0138] That is, for example, the trade-in price determination unit 517 determines the trade-in base amount as the amount obtained by multiplying the selling price of the secondary battery RB to be traded in by a specified cost rate, or the amount obtained by subtracting a specified profit amount from the selling price. Alternatively, the trade-in base amount calculated in advance may be stored in the server storage unit 530 in the same way, and the trade-in price determination unit 517 determines the trade-in base amount by obtaining the stored trade-in base amount.

[0139] Then, the trade-in price determination unit 517 determines the trade-in price of the secondary battery RB to be traded in at each trade-in facility as the amount obtained by subtracting the above-estimated transportation cost from each trade-in facility to the delivery location from the thus-determined trade-in base amount.

[0140] In addition, when there are multiple pieces of desired purchase information extracted by the extraction unit 511, the selling price, transportation cost, and trade-in price are determined or estimated for each piece of the extracted desired purchase information.

[0141] Next, the trade-in price determination unit 517 sends the information of the trade-in facility with the highest trade-in price and the trade-in price in this trade-in facility to the trade-in requester device 30. In addition, at this time, the trade-in price determination unit 517 may also send the information of the trade-in facilities other than the trade-in facility with the highest trade-in price and the trade-in price in this trade-in facility to the trade-in requester device 30 together.

[0142] Figure 5 It is a schematic diagram showing the outline of the processing flow of S30 to S90 above. Since the deterioration state included in the received trade-in desired information is "75%", the data with the desired purchase ID of "BD0001" and the data of "BD0003" are extracted as the desired purchase information with the deterioration state corresponding to the use of "70% or more".

[0143] Moreover, the trade-in price is determined for each trade-in facility and each piece of desired purchase information. In this embodiment, "○○○ yen" of "○○ Automobile Rock City △△ Store" is selected as the highest trade-in price. In addition, "□△△ yen" of "○○ Automobile Rock City □□ Store" is selected as the second highest trade-in price.

[0144] Next, the trade-in facility information output unit 313 of the trade-in requester device 30 receives the information of the trade-in facility with the highest trade-in price and displays it on the trade-in requester device output unit 370 ( Figure 3A / S100), and ends the processing.

[0145] Figure 6 It is a schematic diagram showing the output content in the trade-in requester device 30. In the map MA, the information indicating the trade-in facility with the highest trade-in price and the display IBP indicating the trade-in price in this trade-in facility are displayed. In addition, the information indicating the trade-in facility with the second highest trade-in price, the display ISBP indicating the trade-in price in this trade-in facility, and the display IPP indicating the current position of the trade-in requester S are also displayed together.

[0146] In the present embodiment, since the information indicating the location of the trade-in facility with the highest trade-in price and the display of the trade-in price in this trade-in facility are made different from the display of information on other trade-in facilities in this way, it is thus possible for the trade-in applicant S to understand that although the □□ store is closer to the current location, the trade-in price at the △△ store is higher, thereby prompting the applicant to conduct a trade-in at the △△ store with the highest trade-in price.

[0147] Next, with reference to Figure 3B , a series of processes until the secondary battery RB for trade-in is delivered to the purchaser B who wishes to buy will be described. This series of processes in the present embodiment is executed at any time, for example, according to the operation of the person in charge of the trade-in facility using the server 50.

[0148] At the start of the process, first, the trade-in information processing unit 519 of the server 50 receives information related to the secondary battery RB for trade-in according to the operation of the person in charge of the trade-in facility, and stores it in the used secondary battery DB535 of the server storage unit 530 ( Figure 3B / S110).

[0149] Next, the reservation information receiving unit 113 of the purchaser device 10, for example, acquires information related to the secondary battery for trade-in according to the operation of the purchaser B using the purchaser device 10 and displays it on the purchaser device output unit 170 ( Figure 3B / S120).

[0150] That is, for example, the reservation information receiving unit 113 first refers to the purchaser DB533 to extract the purchaser's purchase wish information, and then refers to the used secondary battery DB535 to select the trade-in wish information in which the usage included in the extracted purchase wish information matches the degradation state included in the above trade-in wish information. Then, the reservation information receiving unit 113 displays the purchase wish information and the corresponding trade-in wish information thus extracted on the purchaser device output unit 170.

[0151] Then, the reservation information receiving unit 113 receives information from the purchaser B indicating a reservation to purchase the secondary battery RB for trade-in and sends it to the server 50 ( Figure 3B / S130).

[0152] That is, for example, the reservation information receiving unit 113 sends the corresponding purchase wish ID and used secondary battery ID to the server 50 according to the operation of the purchaser B selecting the secondary battery RB to be reserved.

[0153] Next, the trade-in information processing unit 519 of the server 50 receives information indicating a reservation to purchase a secondary battery for trade-in and stores it in the server storage unit 530, thus ending a series of processes ( Figure 3B / S140).

[0154] That is, for example, it receives a desired purchase ID and a used secondary battery ID. Based on the used secondary battery ID, it refers to the used secondary battery DB and writes the received desired purchase ID in the reservation completion field of the corresponding record, and then stores it in the server storage unit 530.

[0155] In addition, the person in charge of each trade-in facility can confirm the reservation status of the secondary battery for trade-in at any time through the server output unit 570. In addition, when the delivery to the delivery place is completed, for example, the corresponding desired purchase information and desired trade-in information are deleted from each DB in the server storage unit 530.

[0156] As described above, according to the used secondary battery reuse system of the present invention, the transportation cost of the used secondary battery can be reduced and the used secondary battery can be sold at a low price.

[0157] The embodiments of the present invention have been described above, but the present invention is not limited thereto. Various changes can be made without departing from the gist of the present invention. In addition, some functions, processes can be omitted as needed, or the order of processes can be changed.

[0158] For example, the trade-in price determination unit 517 may be configured to exclude information related to trade-in facilities with a trade-in price below a specified amount from the transmission targets when sending information indicating the trade-in facility and the trade-in price in the trade-in facility to the device 30 of the person wishing to trade in.

[0159] Or, for example, in the above, a structure for obtaining information related to the secondary battery traded in according to the operation of the purchaser B and displaying it on the output unit 170 of the purchaser device has been described, but it is not limited thereto. That is, for example, the trade-in information processing unit 519 may be configured to automatically send information notifying this situation to the purchaser device 10 when receiving information about the secondary battery RB that matches the desired purchase information.

[0160] Or, for example, some functions of the device 30 of the person wishing to trade in can also be implemented by other devices communicably connected to the device 30 of the person wishing to trade in. That is, for example, the function of obtaining the deterioration state (SOH) of the secondary battery RB in the function of the trade-in information receiving unit 311 can be installed in this other device.
