Summary of the Invention

Problems to be Solved by the Invention

[0004] The power storage device mounted on an electric vehicle may be circulated separately due to the difference in the progress of deterioration from the vehicle body. Therefore, a sales form in which the vehicle body and the power storage device are sold separately as used products can be considered. When selling a used car that combines a used vehicle body and a used power storage device in such a sales form using a website or the like, a plurality of combinations of the vehicle body and the power storage device can be considered as compared with the case of selling the vehicle alone. Therefore, it is required to quickly provide information on the used car desired by the purchaser from among such combinations.

[0005] The present disclosure has been made to solve the above-described problems, and an object thereof is to provide a used car sales system capable of quickly providing information on a used electric vehicle desired by a purchaser.

Means for Solving the Problems

[0006] A used car sales system according to an aspect of the present disclosure is a used car sales system used for the used sales of a power storage device and a vehicle body capable of mounting the power storage device. This used car sales system includes a management server that manages information about a plurality of vehicle bodies and information about a plurality of power storage devices that can be mounted on at least any one of the plurality of vehicle bodies, and a terminal including a display unit and capable of communicating with the management server. When the management server receives information indicating a selection target among the plurality of vehicle bodies from the terminal, the management server causes the display unit to display first information about the plurality of power storage devices that can be mounted on the selection target and second information about the cruising range when the selection target and the power storage device are combined.

[0007] In this way, since a plurality of power storage devices that can be mounted on the selected vehicle body are displayed together with the cruising range, it becomes possible for a prospective purchaser to quickly select a used electric vehicle that the purchaser desires.

[0008] In one embodiment, the management server causes the display unit to display, in a non-selectable manner, information about a power storage device for which conditions regarding predetermined performance of an electric vehicle are not satisfied when combined with the selection target.

[0009] In this way, a power storage device that, although capable of being mounted on the vehicle body, does not satisfy the conditions regarding predetermined performance when combined is displayed in a non-selectable manner. Therefore, it is possible to suppress the selection of the power storage device, and it is possible to make a prospective purchaser recognize that the power storage device is capable of being mounted on the selected vehicle body but cannot be selected.

[0010] Furthermore, in one embodiment, the management server sets information about a power storage device that cannot be mounted on the selection target as a non-display target.

[0011] In this way, it is possible to suppress the display of unnecessary information for a prospective purchaser.

[0012] In yet another embodiment, in addition to the first information and the second information, the management server causes the display unit to display information about the price when a selection target and a power storage device are combined.

[0013] By doing so, in addition to the first information and the second information, information about the price when a selection target and a power storage device are combined is displayed on the display unit, so that information about the used price of the electric vehicle can be provided to the potential purchaser.

Effect of the Invention

[0014] According to the present disclosure, it is possible to provide a used car sales system that can quickly provide information about a used electric vehicle desired by a purchaser.

Embodiments for Carrying Out the Invention

[0016] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and their description will not be repeated.

[0017] FIG. 1 is a diagram schematically showing an example of the overall configuration of a used car sales system 10. Referring to FIG. 1, the used car sales system 10 includes a plurality of terminals 20 and a management server 30. Each of the plurality of terminals 20 and the management server 30 are configured to be communicable with each other via a communication network 50 such as the Internet.

[0018] The terminal 20 is a computer owned by a purchaser who wishes to purchase a used car, and may be a mobile terminal such as a smartphone or a tablet, or may be a laptop PC (Personal Computer), a desktop PC, or the like. The terminal 20 includes a control device, a storage device, a communication device, an input interface (none of which are shown), and a display unit 22.

[0019] The management server 30 is a computer that manages the aggregation and sale of used vehicle bodies and used batteries held by used car dealerships. The vehicle body is, for example, an electric vehicle such as an electric car or a hybrid car, and corresponds to the vehicle part excluding the battery. The battery is a power storage device that can be mounted on at least any one of a plurality of types of vehicle bodies. The vehicle body and the battery are treated as separate sales targets. That is, a purchaser can select a vehicle body and a battery, and purchase a used electric vehicle by combining the selected vehicle body and battery.

[0020] When there are a plurality of used car dealerships, the management server 30 acquires, via the communication network 50, information on vehicle bodies for sale (manufacturer, vehicle type name, model, year model, vehicle weight, vehicle body price, etc.) and information on batteries for sale (product number, compatible vehicle types, current full charge capacity, battery weight, battery price, etc.) from computers (not shown) installed in each of the plurality of used car dealerships. The management server 30 stores the acquired information.

[0021] The management server 30 has a function as a web server. The management server 30 uses the above-described stored information to post information about the vehicle body to be sold and information about the battery to be sold on the online sales site in a predetermined display format. Further, the management server 30 executes a process (such as a settlement process) of selling the vehicle body and the battery to be sold that are selected on the online sales site and for which a purchase request is received.

[0022] FIG. 2 is a diagram showing an example of the configuration of the management server 30. Referring to FIG. 2, the management server 30 includes a communication device 310, a storage device 320, and a processing device 330. The communication device 310 is configured to be able to communicate bidirectionally with each terminal 20 through the communication network 50.

[0023] The storage device 320 includes a vehicle body database (hereinafter, the "vehicle body database" is referred to as the "vehicle body DB") 321 and a battery database (hereinafter, the "battery database" is referred to as the "battery DB") 322. The vehicle body DB 321 stores information about the vehicle body to be sold posted on the online sales site. The information of the vehicle body may include, for example, in addition to the above-described manufacturer, vehicle model name, model, model year, vehicle weight, and vehicle body price, the drive system (such as whether it is four-wheel drive or not), and the presence or absence of various equipment. The battery DB 322 stores information about the battery to be sold posted on the online sales site. The information of the battery may include, for example, in addition to the above-described product number, compatible vehicle models, current full charge capacity, battery weight, and battery price, the manufacturing date, manufacturing location, and various history information.

[0024] FIG. 3 is a diagram showing an example of information stored in battery DB322 in tabular form. As shown in FIG. 3, a battery ID is assigned as identification information for identifying all batteries to be sold. Note that the battery ID may be a manufacturing number or a serial number. Further, in battery DB322, a product number, a compatible vehicle type, a current full charge capacity, a battery weight, and a battery price are stored in association with the battery ID. For example, for a battery with a battery ID of "001", a product number "a-1", a compatible vehicle type "A, B", a current full charge capacity "C1", a battery weight "W1", and a battery price "P1" are stored in battery DB322 in association with each other. Note that the compatible vehicle type "A, B" indicates that the battery with a battery ID of "001" is compatible with vehicle types A and B.

[0025] Similarly, for batteries with battery IDs of "002", "003", and "004", as shown in FIG. 3, a product number "a-2", "a-3", "a-4", a compatible vehicle type "A, C", "A, D", "B, D", a current full charge capacity "C2", "C3", "C4", a battery weight "W2", "W3", "W4", and a battery price "P2", "P3", "P4" are respectively associated and stored in battery DB322.

[0026] The processing device 330 includes a CPU (Central Processing Unit), a memory (ROM (Read Only Memory) and RAM (Random Access Memory)), and an input / output buffer (none of which are shown). The CPU expands and executes a program stored in the ROM in the RAM or the like. The program stored in the ROM describes various processes executed by the processing device 330.

[0027] The processing device 330 acquires information on the vehicle body to be sold and battery information posted on the online sales site from the computers of each used car dealership via a communication network. The processing device 330 registers (stores) the acquired information on the vehicle body to be sold in the vehicle body DB 321 and registers the acquired battery information to be sold in the battery DB 322.

[0028] When the processing device 330 is connected to the online sales site (that is, when receiving a display request for the online sales site), for example, using an app or the like of the terminal 20, the processing device 330 transmits information (image data, site configuration information, etc.) for displaying the online sales site to the terminal 20.

[0029] When the online sales site is displayed on the display unit 22 of the terminal 20, the user (prospective purchaser) of the terminal 20 can recognize the vehicle body and battery to be sold. When the prospective purchaser operates the input interface of the terminal 20 and completes a selection operation for selecting the vehicle body and battery, the terminal 20 transmits information indicating the selection operation to the management server 30. The management server 30 generates display information using the received information indicating the selection operation and transmits the generated display information to the terminal 20. The terminal 20 changes the display content using the display information received from the management server 30. By such information being exchanged between the terminal 20 and the management server 30, a process is performed in which the prospective purchaser selects the vehicle body and battery to be sold and purchases an electric vehicle combining the selected vehicle body and battery.

[0030] In the used car sales system 10 as described above, since the battery is circulated separately from the vehicle body due to the difference in the progress of deterioration, a sales form in which the vehicle body and the battery are sold separately as used items as described above is conceivable. When selling used vehicle bodies and used batteries in such a sales form using an online sales site or the like, since a plurality of combinations of the vehicle body and the battery are conceivable compared to the case of selling by vehicle unit, it is required to promptly provide information on the used car desired by the prospective purchaser from among such combinations.

[0031] Therefore, in the present embodiment, when the management server 30 receives information indicating any one of a plurality of vehicle bodies from the terminal 20, the management server 30 causes the display unit 22 of the terminal 20 to display first information about a plurality of batteries that can be mounted on the selection target and second information about the cruising range when the selection target and the power storage device are combined.

[0032] In this way, since a plurality of batteries that can be mounted on the selected vehicle body are displayed together with the cruising range, it becomes possible for a prospective purchaser to quickly select a used electric vehicle that the purchaser desires. Note that the "cruising range" indicates the distance that can be traveled when the mounted battery is fully charged (i.e., with a single charge).

[0033] Hereinafter, an example of the processing executed in the management server 30 will be described with reference to FIG. 4. FIG. 4 is a flowchart showing an example of the processing executed in the management server 30 (specifically, the processing device 330). A series of processes shown in this flowchart are repeatedly executed by the management server 30 at predetermined intervals.

[0034] In step (hereinafter, steps are described as S) 100, the management server 30 determines whether or not a display request for a selection screen is received. The selection screen is a screen for a prospective purchaser to select a vehicle body and a battery on a used car sales site. For example, when the application of the terminal 20 is started and the management server 30 receives an operation of the prospective purchaser for connecting to an online sales site, the terminal 20 transmits a connection request to the management server 30. When the management server 30 receives the connection request, it determines that a display request for the selection screen is received. If it is determined that a display request for the selection screen is received (YES in S100), the process proceeds to S102.

[0035] In S102, the management server 30 acquires vehicle body information. The management server 30 acquires information on the vehicle body (vehicle body information) of the vehicle body to be sold from the vehicle body DB 321. Note that the management server 30, for example, registers in the vehicle body DB 321 by associating flag information indicating whether each of a plurality of vehicle IDs is a sales target, and acquires the vehicle body information for the vehicle ID corresponding to the flag in the on state as the vehicle body information of the vehicle to be sold. The management server 30 acquires at least the manufacturer, the vehicle model name, the model, the model year, the vehicle weight, and the vehicle body price as the vehicle body information. The subsequent process proceeds to S104.

[0036] In S104, the management server 30 displays selectable vehicle models. For example, when the manufacturer is specified by the purchaser, the management server 30 identifies all vehicle models corresponding to the specified manufacturer included in the vehicle body information as selectable vehicle models, sets display information for displaying the identified selectable vehicle models, and transmits the set display information to the terminal 20. The terminal 20 uses the display information to display the selectable vehicle models on the display unit 22. The subsequent process proceeds to S106.

[0037] In S106, the management server 30 determines whether vehicle model selection information has been received. When the terminal 20 receives an operation by the purchaser and one of the selectable vehicle models displayed on the display unit 22 is selected, the terminal 20 transmits information indicating the selected vehicle model to the management server 30 as the vehicle model selection information. When it is determined that the vehicle model selection information has been received (YES in S106), the process proceeds to S108.

[0038] In S108, the management server 30 identifies the selected vehicle model. The management server 30 identifies the selected vehicle model using the received vehicle model selection information. The subsequent process proceeds to S110.

[0039] In S110, the management server 30 extracts compatible batteries. The management server 30 extracts batteries that are compatible with a specified selected vehicle model among the battery information stored in the battery DB322. For example, the management server 30 extracts compatible batteries by searching for the compatible vehicle models of the battery information and extracting the battery IDs that include the same vehicle model as the selected vehicle model as the compatible vehicle models. The subsequent process proceeds to S112.

[0040] In S112, the management server 30 calculates the estimated cruising range. The management server 30 calculates the estimated cruising range when the battery extracted as the compatible battery is installed in the selected vehicle model. For example, the management server 30 calculates the vehicle weight after installing the battery from the battery weight of the extracted battery and the vehicle weight of the selected vehicle model, and uses the calculated vehicle weight and the current full charge capacity of the battery to calculate the maximum value of the travelable distance in one charge as the estimated cruising range. As a method for calculating the maximum value of the travelable distance, for example, the power consumption per unit distance during steady driving is calculated from the calculated vehicle weight, and the travelable distance when the battery is charged until the current full charge capacity is reached is calculated as the estimated cruising range. Note that as long as a known technique is used for the method of calculating the estimated cruising range, it is not particularly limited to the above method. For example, a map, a function, or the like showing the relationship between the vehicle weight, the current full charge capacity, and the estimated cruising range may be pre - adapted by experiments or the like, and the management server 30 may calculate the estimated cruising range from the calculated vehicle weight and the current full charge capacity based on the relationship. Alternatively, it may be calculated in consideration of the output of the motor serving as the drive source or the like. The subsequent process proceeds to S114.

[0041] In S114, the management server 30 extracts batteries with substandard performance. For example, the management server 30 extracts, as batteries with substandard performance, batteries among the batteries extracted as compliant batteries whose estimated cruising range is equal to or less than a threshold value. The management server 30 may, for example, extract, as batteries with substandard performance, batteries for which the value obtained by adding the vehicle body weight and the battery weight exceeds a threshold value. Alternatively, the management server 30 may extract, as batteries with substandard performance, batteries for which the ratio of the battery weight to the vehicle weight exceeds or falls below a predetermined range. Further, for example, the management server 30 may extract, as batteries with substandard performance, cases where the current full charge capacity is equal to or less than a threshold value set according to the vehicle type. The subsequent process proceeds to S116.

[0042] In S116, the management server 30 displays selectable batteries and batteries with substandard performance. The management server 30 sets display information for displaying selectable batteries and batteries with substandard performance using information about selectable batteries and information about batteries with substandard performance, and transmits the set display information to the terminal 20. The terminal 20 displays selectable batteries and batteries with substandard performance on the display unit 22 using the display information. At this time, the terminal 20 displays the selectable batteries in a selectable manner as purchase targets, and displays the batteries with substandard performance in a non-selectable manner as purchase targets. An example of the configuration displayed on the display unit 22 of the terminal 20 will be described later. The subsequent process proceeds to S118.

[0043] In S118, the management server 30 determines whether or not to receive battery selection information. When any one of the selectable batteries displayed on the display unit 22 is selected by the terminal 20 in response to an operation by a purchaser, the terminal 20 transmits information indicating the selected battery to the management server 30 as battery selection information. When it is determined that the battery selection information is received (YES in S118), the process proceeds to S120.

[0044] In S120, the management server 30 calculates the selling price. The management server 30 calculates, as the selling price, the amount obtained by adding the battery price of the selected battery to the vehicle body price of the selected vehicle body. Then the process proceeds to S122.

[0045] In S122, the management server 30 displays the calculated selling price. The management server 30 sets display information for displaying the selling price using the information about the calculated selling price, and transmits the set display information to the terminal 20. The terminal 20 displays the selling price on the display unit 22 using the said display information. Then the process ends.

[0046] Note that when it is determined that a display request for the selection screen is not received (NO in S100), this process ends. Also, when it is determined that vehicle type selection information is not received (NO in S106), the process returns to S106. Further, when it is determined that battery selection information is not received (NO in S118), the process returns to S118.

[0047] An example of the operation of the management server 30 of the used car sales system 10 based on the above structure and flowchart will be described with reference to FIG. 5. FIG. 5 is a diagram showing an example of the configuration of the display screen on the display unit 22 of the terminal 20.

[0048] For example, when a prospective purchaser connects to the used car sales site by launching an app on the terminal 20 or the like, a connection request is transmitted from the terminal 20 to the management server 30.

[0049] When a connection request is received as a display request for the selection screen in the management server 30 (YES in S100), vehicle body information is acquired from the vehicle body DB 321 (S102), and information for displaying selectable vehicle models is generated and transmitted to the terminal 20 (S104). When the terminal 20 performs display using the received information, as shown in FIG. 5(A), a selection screen is displayed. On the selection screen, the names of vehicle models subject to sale and the prices of the vehicle bodies are displayed in tabular form. In FIG. 5(A), "A", "B", and "C" are displayed as vehicle models, and "L", "M", and "N" are displayed as examples of the respective prices. Note that although only three vehicle models are displayed as an example in FIG. 5(A), the number of displayed models is not limited to three, and may be four or more, or the number of displayed models may be limited by specifying the manufacturer, model year, etc. Also, different vehicle models may be displayed, or multiple identical vehicle models may be displayed.

[0050] When a purchaser performs an operation of selecting one of the multiple vehicle models displayed on the selection screen, information indicating the selected vehicle model is transmitted from the terminal 20 to the management server 30 as vehicle model selection information. When the management server 30 receives the vehicle model selection information (YES in S106), the vehicle model selected by the purchaser is identified using the received vehicle model selection information (S108). When the vehicle model is identified, a compatible battery that is compatible with the identified vehicle model is extracted (S110). Then, the estimated cruising range when the extracted compatible battery is installed in the selected vehicle model is calculated (S112). Further, substandard batteries are extracted using the battery weight, estimated cruising range, etc. (S114). Subsequently, the selectable batteries and substandard batteries extracted later are displayed on the display unit 22 of the terminal 20 (S116).

[0051] In FIG. 5(B), for example, an example of the configuration of the display screen when the vehicle model "A" is selected is shown. As shown in FIG. 5(B), on the display unit 22 of the terminal 20, batteries that can be installed for the vehicle model "A" are displayed as selection candidates. In FIG. 5(B), product numbers "a-1", "a-2", and "a-3" are displayed. Also, for the battery with the product number "a-1", the price "P" and the travelable distance "X" are displayed in association with each other. Similarly, for the battery with the product number "a-2", the price "Q" and the travelable distance "Y" are displayed in association with each other. On the other hand, for the battery with the product number "a-3", the price "R" is displayed in association with it, and character information "Cannot be selected due to insufficient performance" is displayed in the area on the right side of the price information. Also, in the part where the character information of the batteries with the product numbers "a-1" and "a-2" is described, the character information is surrounded by a solid line frame, while in the part where the character information of the battery with the product number "a-3" is described, the character information is surrounded by a dashed line frame and displayed. In this way, for the battery with the product number "a-3", by including a display that is partially different from other selectable batteries, it is visually recognizable that the product number "a-3" is in a non-selectable state. At this time, for the battery with the product number "a-3", for example, it is set as a non-selectable option, and even if an operation is performed by a person who wishes to purchase on the terminal 20 to select the product number "a-3", it is processed so that it does not become a selected state as a purchase target.

[0052] When an operation is performed on the terminal 20 to select a battery (for example, the battery with the product number "a-1"), information about the selected battery is transmitted from the terminal 20 to the management server 30 as battery selection information. When the management server 30 receives the battery selection information (YES in S118), a value obtained by adding the body price of the selected vehicle model and the battery price of the selected battery (for example, L + P) is calculated as the selling price (S120), and information for displaying the calculated selling price is transmitted to the terminal 20 (S122). When the terminal 20 receives the information from the management server 30, character information indicating the calculated selling price is displayed on the display unit 22.

[0053] As described above, according to the used car sales system 10 according to the present embodiment, since a plurality of batteries that can be mounted on the vehicle body to be selected are displayed together with the estimated cruising range, it becomes possible for a prospective purchaser to quickly select a used electric vehicle that the purchaser desires. Therefore, it is possible to provide a used car sales system that can quickly provide information about the used electric vehicle desired by the purchaser.

[0054] Furthermore, batteries that can be mounted on the vehicle body but have substandard performance when combined are displayed in a non-selectable manner. Therefore, it is possible to suppress the selection of such batteries and to make the prospective purchaser recognize that such batteries can be mounted on the vehicle body but cannot be selected.

[0055] Furthermore, in addition to the information about the batteries (first information) that can be mounted on the vehicle body to be selected and the information about the estimated cruising range (second information) when the vehicle body to be selected, the battery, and the battery are combined, information about the price when the vehicle body to be selected and the power storage device are combined is displayed, so that the purchaser can recognize the price of the used electric vehicle desired by the purchaser.

[0056] Furthermore, since batteries that cannot be mounted on the vehicle body to be selected are set as non-display targets, it is possible to suppress the display of unnecessary information for the prospective purchaser and to enable the prospective purchaser to quickly select the used electric vehicle desired by the purchaser.

[0057] Hereinafter, modified examples will be described.

[0058] In the above-described embodiment, it has been described that a screen for selecting a vehicle type as shown in FIG. 5(A) is displayed, and after the vehicle type is selected, a screen for selecting a battery as shown in FIG. 5(B) is displayed. However, a screen for selecting a vehicle type may be displayed in one of two regions divided left and right or up and down on the screen, and a screen for selecting a battery may be displayed in the other. And each time the selection of the vehicle type is changed, the screen for selecting a battery may be updated. By doing so, it is possible to facilitate the change of the vehicle type and promptly display the battery corresponding to the changed vehicle type.

[0059] Furthermore, in the above-described embodiment, in the screen for selecting a vehicle type as shown in FIG. 5(A), the case of displaying the vehicle type and the price has been described as an example. However, for example, at least any one of the manufacturer, model year, model, and vehicle weight may be displayed in addition to the vehicle type and the price.

[0060] Furthermore, in the above-described embodiment, in the screen for selecting a battery as shown in FIG. 5(B), the case of displaying the product number, the price, and the travelable distance has been described as an example. However, for example, at least any one of the compatible vehicle types, the current full charge capacity, and the battery weight may be displayed in addition to the product number, the price, and the travelable distance.

[0061] Note that the above-described modified examples may be implemented by appropriately combining all or part of them.

[0062] The embodiments disclosed this time should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is shown not by the above description but by the claims, and it is intended that all modifications within the meaning and scope equivalent to the claims are included.
