The present invention relates to a used secondary battery reuse system.
A system capable of specifying, when reusing a used secondary battery in another field, an appropriate secondary battery according to the reuse destination is conventionally proposed (see Patent Literature 1).
With this prior art technique, the residual value of each storage battery is calculated based on operation history information of the storage battery, and a storage battery whose residual value satisfies demand information to be satisfied by a storage battery required by a reuse system is selected based on the residual value information.
The transportation cost of a used secondary battery from a storage site to a use site is included in the total amount paid by a purchaser of the used secondary battery. If the transportation cost is high, the total amount of payment is high even when the used secondary battery can be prepared inexpensively. In such a case, the user hesitates about purchasing the used secondary battery.
The prior art technique fails to take into consideration the transportation cost of the used secondary battery from the storage site to the use site. Since there is a possibility that the total amount to be paid by the user when purchasing the used secondary battery is high, wider use of used secondary batteries is hindered.
The present invention therefore has an object of providing a system that can reduce the transportation cost of a used secondary battery and sell the used secondary battery inexpensively.
A used secondary battery reuse system according to the present invention is a used secondary battery reuse system that supports reuse of a used secondary battery used as a secondary battery for vehicle driving, including: a storage unit configured to store position information of each of a plurality of trade-in facilities for trading in a vehicle on which the secondary battery is mounted; a purchase request information reception unit configured to receive, from a purchase applicant who wants to purchase the used secondary battery, purchase request information for the used secondary battery including an intended use of the used secondary battery and position information of a delivery site, and store the purchase request information in the storage unit; a trade-in request information reception unit configured to receive, from a trade-in applicant who wants to trade in the vehicle, trade-in request information including information indicating a degradation state of the secondary battery mounted on the vehicle; an extraction unit configured to extract the purchase request information including the intended use of the used secondary battery that matches the degradation state included in the trade-in request information; a sale price determination unit configured to determine a sale price of the secondary battery to be traded in for the purchase applicant, depending on the intended use of the used secondary battery related to the extracted purchase request information; a transportation cost estimation unit configured to estimate, based on the position information of the delivery site included in the extracted purchase request information and the position information of each of the plurality of trade-in facilities, a transportation cost of the secondary battery to be traded in from each trade-in facility to the delivery site; and a trade-in price determination unit configured to determine a trade-in price of the secondary battery to be traded in in each trade-in facility, based on the sale price and the transportation cost of the secondary battery to be traded in.
In the used secondary battery reuse system according to the present invention, the extraction unit extracts the purchase request information including the intended use of the used secondary battery that matches the degradation state included in the trade-in request information, and the sale price determination unit determines the sale price of the secondary battery to be traded in for the purchase applicant depending on the intended use of the used secondary battery.
Moreover, the transportation cost estimation unit estimates, based on the position information of the delivery site included in the purchase request information and the position information of each of the plurality of trade-in facilities, the transportation cost of the secondary battery to be traded in from each trade-in facility to the delivery site.
Further, the trade-in price determination unit determines the trade-in price of the secondary battery to be traded in in each trade-in facility, based on the sale price and the transportation cost of the secondary battery to be traded in.
In this way, the trade-in price of the secondary battery to be traded in is determined in consideration of the degradation state of the secondary battery to be traded in and the transportation cost based on the position of the delivery site included in the purchase request information and the position of each of the plurality of trade-in facilities. Such a trade-in price is an amount appropriate to the actual state of the secondary battery.
Thus, the used secondary battery reuse system according to the present invention can reduce the transportation cost of the used secondary battery and sell the used secondary battery inexpensively.
Preferably, the used secondary battery reuse system according to the present invention includes a trade-in facility information output unit configured to output the trade-in price in each trade-in facility determined by the trade-in price determination unit and information indicating a position of each trade-in facility, to the trade-in applicant.
In the used secondary battery reuse system according to the present invention, the trade-in facility information output unit outputs the trade-in price in each trade-in facility and the information indicating the position of each trade-in facility to the trade-in applicant.
In this way, the trade-in applicant is informed of the trade-in price in each trade-in facility beforehand, so that the trade-in applicant can sufficiently examine in which trade-in facility the secondary battery is to be traded in. This enhances the trade-in applicant's satisfaction with the trade-in price.
Thus, the used secondary battery reuse system according to the present invention can reduce the transportation cost of the used secondary battery and sell the used secondary battery inexpensively while enhancing the trade-in applicant's satisfaction with the trade-in price.
Preferably, in the used secondary battery reuse system according to the present invention, the trade-in facility information output unit is configured to display information indicating a position of a trade-in facility with a highest trade-in price and the trade-in price in the trade-in facility in a manner different from information about each trade-in facility other than the trade-in facility.
In the used secondary battery reuse system according to the present invention, when outputting the information indicating the trade-in facility with the highest trade-in price and the trade-in price in the trade-in facility to the trade-in applicant, the trade-in facility information output unit displays these information in a manner different from the information about the other trade-in facilities.
In this way, the trade-in applicant can clearly identify the trade-in facility with the highest trade-in price, and therefore efficiently examine in which trade-in facility the secondary battery is to be traded in.
Thus, the used secondary battery reuse system according to the present invention can reduce the transportation cost of the used secondary battery and sell the used secondary battery inexpensively while enabling the trade-in applicant to efficiently examine in which trade-in facility the secondary battery is to be traded in.
Preferably, the used secondary battery reuse system according to the present invention includes: a trade-in information processing unit configured to store information about a traded in secondary battery in the storage unit; a reservation information reception unit configured to receive, from the purchase applicant, information indicating to reserve purchase of the traded in secondary battery, and store the information in the storage unit; and a reservation information output unit configured to output the information indicating to reserve the purchase of the traded in secondary battery stored in the storage unit.
In the used secondary battery reuse system according to the present invention, the reservation information reception unit receives, from the purchase applicant, the information indicating to reserve purchase of the traded in secondary battery, and stores the information in the storage unit.
The reservation information output unit then outputs the stored information indicating to reserve purchase of the traded in secondary battery.
In this way, a person in charge of trade-in of secondary batteries can easily identify which used secondary battery is reserved, and accordingly efficiently manage used secondary battery inventory.
Thus, the used secondary battery reuse system according to the present invention can reduce the transportation cost of the used secondary battery and sell the used secondary battery inexpensively while efficiently managing used secondary battery inventory.
Preferably, in the used secondary battery reuse system according to the present invention, the purchase request information reception unit is configured to receive the purchase request information including information designating a transportation method of the used secondary battery to the delivery site, from the purchase applicant, and the transportation cost estimation unit is configured to estimate the transportation cost based on the information designating the transportation method.
The situation of the delivery site and the like may restrict, for example, the size of a vehicle that can be used for transportation or heavy equipment that can be used for delivery at the site, and the transportation cost may vary responsively.
In the used secondary battery reuse system according to the present invention, the purchase request information reception unit receives the purchase request information including the information designating the transportation method of the used secondary battery to the delivery site, and the transportation cost estimation unit estimates the transportation cost based on the information designating the transportation method.
In this way, the transportation cost is estimated in consideration of the transportation method of the used secondary battery. The transportation cost thus estimated is more appropriate to the actual state.
Thus, the used secondary battery reuse system according to the present invention can reduce the transportation cost of the used secondary battery and sell the used secondary battery inexpensively at an amount appropriate to the actual state.
Preferably, in the used secondary battery reuse system according to the present invention, the transportation cost estimation unit is configured to calculate a distance from each trade-in facility to the delivery site for the secondary battery to be traded in, and estimate, based on the calculated distance, the transportation cost of the secondary battery to be traded in from each trade-in facility to the delivery site.
In the used secondary battery reuse system according to the present invention, the transportation cost estimation unit estimates the transportation cost of the secondary battery to be traded in from each trade-in facility to the delivery site based on the distance from the trade-in facility to the delivery site for the secondary battery to be traded in.
In this way, the transportation cost estimation process is performed based on specific information, namely, distance. This enhances the transportation cost estimation accuracy.
Thus, the used secondary battery reuse system according to the present invention can reduce the transportation cost of the used secondary battery and sell the used secondary battery inexpensively while enhancing the transportation cost estimation accuracy.
Preferably, in the used secondary battery reuse system according to the present invention, the transportation cost estimation unit is configured to exclude each trade-in facility whose distance to the delivery site for the secondary battery to be traded in is greater than or equal to a predetermined distance, from the estimation of the transportation cost.
Trading in the secondary battery at a trade-in facility located far away from the delivery site requires very high transportation cost for delivery. It is therefore not practical to trade in the secondary battery at a trade-in facility far away from the delivery site.
In the used secondary battery reuse system according to the present invention, the transportation cost estimation unit calculates the distance from each trade-in facility to the delivery site for the secondary battery to be traded in, and excludes each trade-in facility for which the calculated distance is greater than or equal to a predetermined distance from the transportation cost estimation.
In this way, each trade-in facility that is practical for use in trade-in is selected and the transportation cost estimation process is performed from the viewpoint of the transportation cost for delivery, so that the transportation cost can be estimated efficiently.
Thus, the used secondary battery reuse system according to the present invention can reduce the transportation cost of the used secondary battery and sell the used secondary battery inexpensively while enhancing the transportation cost estimation efficiency.
Preferably, in the used secondary battery reuse system according to the present invention, the purchase request information reception unit is configured to receive the purchase request information including information designating a desired delivery time of the used secondary battery to the delivery site, the used secondary battery reuse system includes a required degradation state determination unit configured to determine a degradation state required at a time of trade-in of the secondary battery to be traded in, based on the intended use of the used secondary battery and the information designating the desired delivery time included in the purchase request information, and the extraction unit is configured to extract the purchase request information corresponding to the degradation state required at the time of trade-in of the secondary battery to be traded in that matches the degradation state included in the trade-in request information.
In the case where the period from when the used secondary battery is traded in to when the used secondary battery is delivered to the purchase applicant is long, there is a possibility that the degradation state of the used secondary battery in storage progresses. Hence, at trade-in, the trade-in price needs to be determined in consideration of the progress of degradation during storage.
In the used secondary battery reuse system according to the present invention, the required degradation state determination unit determines the degradation state required at the time of trade-in of the secondary battery to be traded in based on the intended use of the used secondary battery included in the trade-in request information and the information designating the desired delivery time.
The extraction unit then extracts the purchase request information corresponding to the degradation state required at the time of trade-in of the secondary battery to be traded in that matches the degradation state included in the trade-in request information.
In this way, the purchase request information is extracted in consideration of the progress of degradation during storage, and the trade-in price for the extracted purchase request information is determined. The trade-in price determined in such a manner is more appropriate to the actual state.
Thus, the used secondary battery reuse system according to the present invention can reduce the transportation cost of the used secondary battery and sell the used secondary battery inexpensively at an amount appropriate to the actual state.

The server output unit 570 outputs information to a person in charge of a trade-in facility, and is, for example, a display.
Processes by the used secondary battery reuse system according to this embodiment will be described below, with reference to
<Overview of Processes>
First, a series of processes until information indicating a trade-in facility with the highest trade-in price and the trade-in price in the trade-in facility are output to the trade-in applicant S will be described below, with reference to
The series of processes by the used secondary battery reuse system according to this embodiment is, for example, executed at any time in response to operation by the purchase applicant B using the purchase applicant device 10.
Upon the start of the processes, first, the purchase request information reception unit 111 in the purchase applicant device 10 receives, from the purchase applicant B who wants to purchase a used secondary battery, purchase request information for the used secondary battery including an intended use of the used secondary battery and position information of a delivery site, and transmits the purchase request information to the server 50 (S10 in
Here, the purchase request information received by the purchase request information reception unit 111 may include information designating a transportation method of the used secondary battery to the delivery site and/or information designating a desired delivery time of the used secondary battery to the delivery site, according to need.
The server storage unit 530 stores the purchase request information received from the purchase applicant device 10 (S20 in
After this, in response to operation by the trade-in applicant S who wants to trade in the vehicle M using the trade-in applicant device 30, the trade-in request information reception unit 311 receives, from the trade-in applicant S, trade-in request information including information indicating the degradation state (SOH) of the secondary battery RB mounted on the vehicle M, and transmits the trade-in request information to the server 50 (S30 in
Various methods of receiving the degradation state (SOH) are available. For example, in the case where the vehicle M itself has a function of displaying the SOH of the secondary battery, the trade-in applicant may input the SOH displayed by the vehicle M manually or through image capture using the trade-in applicant device input unit 350 in the trade-in applicant device 30. Alternatively, the trade-in applicant device input unit 350 may, for example, acquire the degradation state (SOH) of the secondary battery RB mounted on the vehicle M via the vehicle M or, in the case where the trade-in applicant device input unit 350 includes a terminal and a sensor for directly acquiring the degradation state (SOH) of the secondary battery RB from the secondary battery RB, using the terminal and the sensor, to receive the degradation state (SOH).
The extraction unit 511 in the server 50 then receives the trade-in request information (S40 in
More specifically, the extraction unit 511 acquires each set of purchase request information with reference to the purchase request DB 533 in the server storage unit 530, and recognizes the degradation state corresponding to the intended use included in each set of purchase request information with reference to, for example, a table storing each intended use of a used secondary battery and a degradation state corresponding to the intended use as illustrated in
The extraction unit 511 then extracts purchase request information including an intended use corresponding to a degradation state that matches the degradation state included in the trade-in request information.
Prior to the extraction process, the required degradation state determination unit 523 may determine a degradation state required at the time of trade-in of the secondary battery RB to be traded in, based on the intended use of the used secondary battery and the information designating the desired delivery time included in each set of purchase request information. In this case, the extraction unit 511 extracts purchase request information corresponding to a degradation state required at the time of trade-in of the secondary battery RB to be traded in that matches the degradation state included in the trade-in request information.
In detail, for example in the case where the degradation state corresponding to the intended use of the used secondary battery included in purchase request information is 80% and degradation is estimated to progress by 5% until the desired delivery time included in the purchase request information, the required degradation state determination unit 523 determines that the degradation state required at the time of trade-in of the secondary battery RB to be traded in is 85%. In this case, if the degradation state included in the trade-in request information is 85% or more, the extraction unit 511 extracts the purchase request information as purchase request information that matches the degradation state included in the trade-in request information.
Following this, the sale price determination unit 513 determines the sale price of the secondary battery RB to be traded in for the purchase applicant B, depending on the intended use of the used secondary battery related to the purchase request information extracted by the extraction unit 511 (S60 in
More specifically, for example with reference to the table storing each intended use of a used secondary battery and a sale price corresponding to the intended use illustrated in
The transportation cost estimation unit 515 then estimates, based on the position information of the delivery site included in the purchase request information extracted by the extraction unit 511 and the position information of each of the plurality of trade-in facilities, the transportation cost of the secondary battery RB to be traded in from each trade-in facility to the delivery site (S70 in
More specifically, the transportation cost estimation unit 515 specifies, for each of the plurality of trade-in facilities, the transportation path of the used secondary battery RB based on the position information of the delivery site and the position information of the trade-in facility, for example using a known method.
The transportation cost estimation unit 515 then calculates the distance from each trade-in facility to the delivery site for the secondary battery RB to be traded in, for example based on the transportation path. Based on the calculated distance, the transportation cost estimation unit 515 estimates the transportation cost from each trade-in facility to the delivery site by calculating the expenses for the transportation of the used battery RB and the installation of the used battery RB at the site in consideration of the occupancy time of a vehicle used for transportation and equipment used for installation at the site, the required number of personnel and the required time, and other factors that influence the transportation cost.
Here, the transportation cost estimation unit 515 may exclude each trade-in facility whose distance to the delivery site is greater than or equal to a predetermined distance, from the transportation cost estimation.
The trade-in price determination unit 517 then determines the trade-in price of the secondary battery RB to be traded in in each trade-in facility, based on the sale price and the transportation cost of the secondary battery RB to be traded in (S80 in
In detail, for example, the trade-in price determination unit 517 determines, as a trade-in base amount, an amount obtained by multiplying the sale price of the secondary battery RB to be traded in by a predetermined cost rate or an amount obtained by subtracting a predetermined profit from the sale price. Alternatively, the trade-in price determination unit 517 may store the trade-in base amount calculated beforehand in the same way in the server storage unit 530, and acquire the stored trade-in base amount to thus determine the trade-in base amount.
The trade-in price determination unit 517 then determines an amount obtained by subtracting, from the determined trade-in base amount, the transportation cost from each trade-in facility to the delivery site estimated as described above, as the trade-in price of the secondary battery RB to be traded in in the trade-in facility.
In the case where a plurality of sets of purchase request information are extracted by the extraction unit 511, the sale price, the transportation cost, and the trade-in price are determined or estimated for each extracted set of purchase request information.
The trade-in price determination unit 517 then transmits information indicating a trade-in facility with the highest trade-in price and the trade-in price in the trade-in facility, to the trade-in applicant device 30. Here, the trade-in price determination unit 517 may also transmit information indicating at least one trade-in facility other than the trade-in facility with the highest trade-in price and the trade-in price in the trade-in facility to the trade-in applicant device 30.
A trade-in price is then determined for each trade-in facility and for each set of purchase request information. In this example, “∘ ∘ ∘ yen” in “∘ ∘ Automobile Iwaki AA Shop” is selected as the highest trade-in price, and “□ΔΔ yen” in “∘ ∘ Automobile Iwaki □□ Shop” is selected as the second highest trade-in price.
The trade-in facility information output unit 313 in the trade-in applicant device 30 then receives the information indicating the trade-in facility with the highest trade-in price, displays the information by the trade-in applicant device output unit 370 (S100 in
In this example, the information indicating the position of the trade-in facility with the highest trade-in price and the trade-in price in the trade-in facility are displayed in a different manner from the information about the other trade-in facility (or facilities), so that the trade-in applicant S can recognize that □□ Shop is closer to the current position but the trade-in price is higher in ΔΔ Shop. The trade-in applicant S is therefore encouraged to perform trade-in at ΔΔ Shop with the highest trade-in price.
Next, a series of processes until the traded in secondary battery RB is delivered to the purchase applicant B will be described below, with reference to
Upon the start of the processes, first, the trade-in information processing unit 519 in the server 50 receives information about the traded in secondary battery RB in response to operation by the person in charge of the trade-in facility, and stores the received information in the used secondary battery DB 535 in the server storage unit 530 (S110 in
Following this, the reservation information reception unit 113 in the purchase applicant device 10 acquires information about the traded in secondary battery for example in response to operation by the purchase applicant B using the purchase applicant device 10, and displays the acquired information by the purchase applicant device output unit 170 (S120 in
In detail, for example, the reservation information reception unit 113 first extracts the purchase request information of the purchase applicant with reference to the purchase request DB 533, and further selects, with reference to the used secondary battery DB 535, trade-in request information including a degradation state that matches the intended use included in the extracted purchase request information. The reservation information reception unit 113 displays the extracted purchase request information and the corresponding trade-in request information by the purchase applicant device output unit 170.
The reservation information reception unit 113 then receives information indicating to reserve purchase of the traded in secondary battery RB from the purchase applicant B, and transmits the received information to the server 50 (S130 in
In detail, for example, in response to operation by the purchase applicant B to select the secondary battery RB which the purchase applicant B wants to reserve, the reservation information reception unit 113 transmits the corresponding purchase request ID and used secondary battery ID to the server 50.
The trade-in information processing unit 519 in the server 50 then receives the information indicating to reserve purchase of the traded in secondary battery, stores the received information in the server storage unit 530, and ends the series of processes (S140 in
In detail, for example, the trade-in information processing unit 519 receives the purchase request ID and the used secondary battery ID, references the used secondary battery DB based on the used secondary battery ID, and writes the received purchase request ID in the reserved field of the corresponding record to thus store the information in the server storage unit 530.
A person in charge of each trade-in facility can check the reservation status of each traded in secondary battery via the server output unit 570 at any time. When the delivery of a traded in secondary battery to a delivery site ends, for example, the corresponding purchase request information and trade-in request information are deleted from the respective DBs in the server storage unit 530.
As described above, the used secondary battery reuse system according to the present invention can reduce the transportation cost of a used secondary battery and sell the used secondary battery inexpensively.
While an embodiment of the present invention has been described above, the present invention is not limited to such. Various modifications can be made without departing from the gist of the present invention. Moreover, part of the functions or processes may be omitted or the order of the processes may be changed according to need.
For example, the trade-in price determination unit 517 may be configured to, when transmitting information indicating a trade-in facility and a trade-in price in the trade-in facility, exclude information about any trade-in facility whose trade-in price is less than or equal to a predetermined amount from the transmission.
Although the above describes a structure in which information about a traded in secondary battery is acquired in response to operation by the purchase applicant B and displayed by the purchase applicant device output unit 170, the present invention is not limited to such.
