[0050] In addition, the output unit 537 may be configured to output electronic documents such as electronic receipts. In this case, the output unit 537 may be installed as a function of the management device 53 implemented by the control unit 531. For example, the electronic document may be output from the management device 53 to the user terminal 73 and displayed in the user terminal 73. In this case, the user terminal 73 may also be represented as a document display device.

[0051] In addition, the output unit 537 may be configured to output the cost information 555a to the recording unit 555 of the display device 55 via the communication unit 533. In this case, the management device 53 may also include: a display unit that displays an input screen for setting the cost information 555a; and an input unit that receives input of the cost information 555a by the operator. As the display unit, various display devices such as a liquid crystal display can be used as appropriate. Alternatively, the management device 53 may be configured to obtain the cost information 555a from outside the management device 53 through the communication unit 533.

[0052] The display device 55 is configured to present the user 7 with the expenses involved in replacing the battery at the replacement service provider 5. The display device 55 is, for example, an electric bulletin board. The electronic bulletin board has a structure in which light-emitting diodes, light bulbs and other light-emitting bodies are arranged in a grid shape, and information is sent out by flashing the light-emitting bodies. As an electronic bulletin board, it can be an electronic bulletin board that is waterproof, heat-resistant, and cold-resistant and is set outdoors, or it can be an electronic bulletin board that is set indoors. In addition, as an electronic bulletin board, a type called a signage that uses a display such as a liquid crystal for the display area can also be used. In addition, the electronic bulletin board can use a battery installed inside as a power source, or it can be powered by an external power source.

[0053] Figure 3 1 is a block diagram showing an example of the configuration of the display device 55 according to the embodiment. The display device 55 includes a control unit 551 , a communication unit 553 , a recording unit 555 , and a display unit 557 as a hardware configuration.

[0054] The control unit 551 controls the overall operation of the display device 55. The control unit 551 includes a processor and a memory such as a RAM and a ROM. The memory of the control unit 551 stores various data and programs used by the display device 55. The processor of the control unit 551 reads a program from, for example, the ROM or the recording unit 555, and implements various functions of the display device 55 by executing the program loaded into the RAM.

[0055] As an example, the control unit 551 implements a display control function for displaying prices related to battery replacement including information on benefits according to the remaining power of the replaceable battery 9 on the display unit 557 based on the price information 555 a stored in the recording unit 555 .

[0056] The communication unit 553 is configured to be able to communicate with the management device 53 in a wired or wireless manner. In the battery replacement system 1 according to the present embodiment, the communication unit 553 is not an essential configuration and may not be provided.

[0057] The recording unit 555 can appropriately utilize various storage media and storage devices such as ROM, HDD (Hard Disk Drive), SSD (Solid State Drive), flash memory, etc. as a hardware structure. A RAM for temporarily storing data in operation may also be provided in the recording unit 555. The recording unit 555 may also store various data and programs used by the display device 55. The recording unit 555 stores, for example, cost information 555a.

[0058] In addition, the recording unit 555 is typically detachable from the display device 55, and is connected to the management device 53, an external PC, etc. in a detached state to edit the recorded information. In addition, the display device 55 can also be connected to the management device 53, an external PC, etc. in a wired or wireless manner through the communication unit 533 to edit the recorded information.

[0059] Here, the cost information 555a refers to cost information related to battery replacement. The cost information 555a includes at least standard price information and first preferential price information. The standard price information and the first preferential price information are set for each battery type.

[0060] The standard price information is information indicating a battery replacement fee for replacing the replaceable battery 9 mounted on the electric vehicle 71 with another fully charged replaceable battery 9. The standard price information can be set for each charging facility 51, for example.

[0061] The first preferential price information is information indicating a discount (discount) according to the state of the replaceable storage battery 9 before replacement mounted on the electric vehicle 71. The information indicating the state of the replaceable storage battery 9 at least includes information indicating the remaining power (power remaining amount). That is, the first preferential price information is set at least for each remaining power. The discount according to the remaining power is effective from the viewpoint of suppressing overdischarge of the replaceable storage battery 9. Here, the first preferential price information is an example of preferential price information.

[0062] The display unit 557 is a display area in the display device 55 as an electronic bulletin board. The display unit 557 includes a display area for displaying standard price information and a display area for displaying first preferential price information. The display unit 557 has a structure in which light emitting bodies such as light emitting diodes and light bulbs are arranged in a grid shape. In addition, as the display unit 557, a liquid crystal display, a projector, etc. can also be used.

[0063] Next, the operation of the battery replacement system 1 according to the embodiment will be described with reference to the drawings. The flow described below is an example, and the order of steps may be changed, some steps may be deleted, or other steps may be added.

[0064] Figure 4 This is a flowchart showing an example of the flow of the battery replacement service according to the embodiment.

[0065] First, the control unit 551 of the display device 55 displays price information related to battery replacement on the display unit 557 based on the fee information 555a stored in the recording unit 555 (S101). The price information includes preferential information for each remaining power amount. The display of price information will be described later.

[0066] After the user 7 visits the charging facility 51 to replace the battery, the operator of the charging facility 51 removes the battery A (replacement battery 9 ) from the electric car 71 and replaces the battery A with the replacement battery B (replacement battery 9 ) ( S102 ).

[0067] Here, the battery A is an example of a battery before replacement of the mobile body and a battery removed from the mobile body. In addition, the battery B is an example of another battery that has been charged.

[0068] In addition, during the battery replacement, the operator selects a replacement battery 9 having the same battery type as that of the battery A, for example.

[0069] Alternatively, after the storage battery A is placed in the measuring device in S103 , the storage battery B to be replaced may be selected based on the storage battery type read from the storage battery A by an operator or the management device 53 .

[0070] Thus, the operation in the charging facility 51 according to the embodiment includes the steps of removing the replaceable battery 9 from the visited electric vehicle 71 , selecting the replaceable battery 9 to be replaced according to the battery type, and installing the selected replaceable battery 9 into the electric vehicle 71 .

[0071] The operator sets the storage battery A removed from the electric car 71 to the measuring unit 535 (measurement device) of the management device 53 to detect the remaining power ( S103 ).

[0072] Specifically, the control unit 531 of the management device 53 reads the remaining power from the controller of the connected storage battery A. The control unit 531 of the management device 53 reads the battery type from the controller of the connected storage battery A after or simultaneously with reading the remaining power.

[0073] The control unit 531 of the management device 53 obtains the cost information 555a corresponding to the battery type of the battery A from the recording unit 555 of the display device 55, for example. Then, the control unit 531 of the management device 53 calculates the cost involved in the battery replacement based on the remaining power of the battery A, the standard cost (standard price information), and the remaining power preferential information (first preferential price information) (S104).

[0074] That is, the operation in the charging facility 51 according to the embodiment includes the following steps: placing the removed replaceable battery 9 on a measuring device to detect the battery type and remaining power; and calculating the fee based on the detected battery type and remaining power. The calculation of the replacement fee will be described later.

[0075] After calculating the cost of battery replacement, the control unit 531 of the management device 53 outputs a replacement bill (receipt) based on the calculated replacement cost through the output unit 537, thereby demanding the driver (user 7) to pay for it (S105a).

[0076] That is, the operation in the charging facility 51 involved in the embodiment includes the following steps: outputting a receipt (invoice) recording the replacement fee corresponding to the battery type and the remaining power from the register (output unit 537); and charging the driver of the electric car 71 (user 7) for the fee of the receipt. In this way, the battery replacement service involved in the embodiment is provided based on the issuance of the invoice. That is, the management device 53 involved in the embodiment can also be expressed as a invoice issuing device. The output invoice will be described later.

[0077] (About display of price information)

[0078] Figure 5 FIG. 6 is a diagram showing an example of a price display screen 610 displayed on the display device 55 according to the embodiment. Figure 5 As shown, the price display screen 610 includes a battery type display area 611, a standard price display area 613, and a remaining power discount display area 615. Figure 5 In the example of , the battery type display area 611, the standard price display area 613, and the remaining power discount display area 615 are configured such that the vertical axis (row) represents the information of each battery type, and the horizontal axis (column) represents the standard price information and the first discount information. That is, the display unit 557 displays the standard price display area 613 and the remaining power discount display area 615 for each battery type.

[0079] The battery type display area 611 is an area for displaying the battery types of the replaceable batteries 9 that can be provided to the user 7 at the charging facility 51 .

[0080] exist Figure 5 In the example of FIG. 6 , the battery type display area 611 displays the battery types of type A having a capacity of 1.7 kWh, type B having a capacity of 2.0 kWh, and type C having a capacity of 10.0 kWh.

[0081] The standard price display area 613 is an area for displaying standard price information. The standard price information is information indicating the replacement cost per kWh as a standard price, for example. Here, the standard price display area 613 is an example of the first display area.

[0082] exist Figure 5For example, if it is type A with a capacity of 1.7kWh, the standard price is 30.0 Indian rupees per kWh. If it is type B with a capacity of 2.0Kwh, the standard price is 29.0 Indian rupees per kWh. If it is type C with a capacity of 10.0Kwh, the standard price is 27.0 Indian rupees per kWh.

[0083] The standard price information displayed in the standard price display area 613 may be information indicating the replacement cost of each storage battery. In this case, if the capacity is 1.7 kWh, the standard price is 1.7×30 Indian rupees.

[0084] The surplus power preferential display area 615 is an area for displaying the first preferential price information. Here, the surplus power preferential display area 615 is an example of the second display area and the third display area.

[0085] exist Figure 5 In the example of , the first preferential price information is discount information corresponding to the surplus power. The first preferential price information is discount information for the case where the surplus power is 10% or more and the case where the surplus power is 20% or more. Figure 5 In the example of , the first preferential price information shows that if it is type A and type B, a discount of 1.0 Indian rupees per kWh is provided when the surplus power is 10% or more, and a discount of 2.0 Indian rupees per kWh is provided when the surplus power is 20% or more. In addition, the first preferential price information shows that if it is type C, there is no discount when the surplus power is 10% or more, and a discount of 3.0 Indian rupees per kWh is provided when the surplus power is 20% or more. In this way, the first preferential price information can be displayed as a difference from the standard price.

[0086] In addition, in this embodiment, if Figure 5 As shown in the figure, the battery type display area 611, the standard price display area 613, and the remaining power discount display area 615 are arranged adjacent to each other, but the present invention is not limited to this. As long as the user 7 can visually recognize and compare the standard price and the remaining power discount as the first discount information for each battery type, it can be relative to Figure 5 In the example of the vertical axis and the horizontal axis being reversed, the areas may be displayed sequentially at the same position. In addition, a space for displaying the date and time (time period), station information (for example, see Fig.12 ) area, or an area for displaying other information such as an area for displaying advertising information. In other words, the price display screen 630 can be information for each time period and each charging station.

[0087] In this way, in the storage battery replacement service according to the embodiment, the first preferential price information according to the surplus power is set and displayed.

[0088] According to this configuration, the user 7 can be guided to bring the replaceable battery 9 to the charging station before the replaceable battery 9 mounted on the electric vehicle reaches overdischarge. Thus, the battery replacement service can be provided while suppressing the degradation of the replaceable battery 9, that is, suppressing the reduction of the asset value of the replaceable battery 9.

[0089] Furthermore, in the battery replacement service according to the embodiment, the first preferential price information is set and displayed according to the battery type.

[0090] Generally speaking, the level of overdischarge that causes battery deterioration varies according to the capacity of the battery and the type of battery. Therefore, from the perspective of suppressing the deterioration of the replaceable battery 9, it is useful to change the first preferential price information according to the type of battery. For example, for a large-capacity replaceable battery 9 such as type C, it is assumed that the battery has a high tendency to deteriorate unless the remaining power is more than 20%. In such a case, in the battery replacement service involved in the embodiment, by setting the discount fee to 0 for the case where the remaining power is more than 10%, the user can be guided to replace the battery when the remaining power is more than 20%.

[0091] (About the issuance of documents)

[0092] Figure 6 This is a diagram showing an example of a receipt issued by the management device 53 according to the embodiment. Figure 6 The receipt 710 for claiming the replacement fee issued when a discount according to the surplus power is applied to the replacement fee related to the replacement of the storage battery is illustrated.

[0093] like Figure 6 As shown, receipt 710 includes replacement fee information 711 , fee detailed information 713 , and remaining power discount information 715 .

[0094] The replacement cost information 711 is information indicating the replacement cost (total amount) after applying a discount related to battery replacement.

Figure 6 In the example of FIG. 1 , the total amount of the battery replacement is printed as 49.30 Indian rupees for the replacement battery 9 of type A with a capacity of 1.7 kWh.

[0096] The fee detailed information 713 is information showing the details of the amount.

[0097] exist Figure 6 In the example of FIG. 7 , regarding the detailed fee information 713 , information on the standard price, the electricity amount discount ratio at the time of return, the discounted price, the battery type, and the battery replacement fee is printed.

[0098] As a standard price, INR 30.00 per kWh for Type A is printed.

[0099] The power amount discount ratio at the time of return is the first preferential price information corresponding to the surplus power. As the power amount discount ratio at the time of return, the case where a discount of 1.0 Indian rupees per kWh is applied is printed. As printed as the surplus power discount information 715, the first preferential price information is calculated based on the power surplus at the time of return being 0.25 kWh, that is, 14.7%.

[0100] As the discounted price, 29.00 Indian rupees per kWh is printed. This discounted price is calculated by applying a discount (-1.0 Indian rupees / kWh) corresponding to the surplus power to the standard price (30.00 Indian rupees / kWh).

[0101] As the battery type, type A with a capacity of 1.7 kWh is printed.

[0102] As the battery replacement fee, 49.30 Indian rupees are printed. The battery replacement fee is calculated based on the discounted price of 29.00 Indian rupees per kWh and the capacity of Type A is 1.7 kWh.

[0103] The surplus power preferential information 715 is information that is the basis for the preferential rate of the amount of power at the time of return of the fee detailed information 713 , and is information indicating the battery state of the replaced battery 9 to be returned.

[0104] exist Figure 6 In the example, as the surplus power preferential information 715, the battery type, battery ID, remaining power at return (remaining power), and preferential discount information are printed. As the remaining power at return, the case where the remaining power at return is 0.25 kWh, that is, 14.7%, is printed. As the preferential discount, the case where the discount corresponding to the surplus power is 1.0 Indian rupees / kWh is printed. The preferential discount is determined based on the fact that the surplus power is greater than 10% and less than 20%.

The acquisition function stores the remaining power and the battery type as the battery information 735c in the recording unit 735. In addition, the acquisition function stores the information related to overload as the driving LV information 735b in the recording unit 735.

[0137] Here, the information on overload is, for example, information indicating the number of times overload was applied to the replaceable battery 9 due to sudden start and / or sudden deceleration. The information on overload is collected by, for example, a controller of the replaceable battery 9 and stored in a recording area in the controller.

[0138] In addition, there may be a case where the fee information 735a is stored in a recording area in the controller of the replaceable storage battery 9. In this case, the control unit 731 implements an acquisition function of acquiring the fee information 735a from the communication interface of the electric vehicle 71 or the controller of the replaceable storage battery 9 mounted on the electric vehicle 71 through the communication unit 733. The acquisition function stores the fee information 735a in the recording unit 735.

[0139] As an example, the control unit 731 realizes a level determination function for determining the level (driving LV) of the Eco driving of the user 7 based on the information related to the overload.

[0140] As an example, the control unit 731 implements a display control function that determines the display format of the cost associated with replacement of the replaceable battery 9 based on the cost information 735a, the driving LV information 735b, and the battery information 735c.

[0141] The communication unit 733 is configured to be able to communicate with the management device 53 or the display device 55 in a wired or wireless manner.

[0142] In addition, the communication unit 733 may be configured to communicate with a server device on the cloud that provides fee information 735a including station information. Communication with the cloud may also be performed via the management device 53 or the display device 55. In addition, the communication unit 733 may be configured to communicate with the electric vehicle 71. In addition, communication with the replaceable storage battery 9 may also be performed via the communication interface of the electric vehicle 71.

[0143] The recording unit 735 can appropriately utilize various storage media and storage devices such as ROM, HDD (Hard Disk Drive), SSD (Solid State Drive), flash memory, etc. as a hardware structure. A RAM for temporarily storing data in operation may also be provided in the recording unit 735. The recording unit 735 may also store various data and programs used by the user terminal 73. The recording unit 735 stores, for example, fee information 735a, driving LV information 735b, and battery information 735c.

[0147] The driving LV information 735 b is information indicating a level of economical driving that can suppress degradation of the battery. The driving LV information 735 b is set by the control unit 731 .

[0148] Here, the level of economical driving refers to information indicating the degree of load applied to the replaceable battery 9 by driving. The level of economical driving is set lower than driving that applies an overload to the replaceable battery 9. In driving that applies an overload, there are sudden starts and sudden decelerations. Driving that applies an overload causes a sudden change in the discharge amount of the replaceable battery 9 by driving the electric motor of the electric vehicle 71, which may promote the deterioration of the replaceable battery 9.

[0149] The battery information 735 c includes at least information indicating the battery type and remaining voltage of the replaceable battery 9 mounted on the electric vehicle 71 .

[0150] As the display unit 737, a liquid crystal display, an organic EL display, a projector, etc. can be appropriately used. It is assumed that the display unit 737 involved in the embodiment is integrally configured as a touch panel display with a touch panel for accepting user operations. In addition, as the display unit 737, a watch-type or glasses-type wearable device worn by the user 7 can also be used. In addition, the user terminal 73 can also have an input unit such as a keyboard, a mouse, and a button for accepting user operations.

[0151] Furthermore, the control unit 731 may acquire the fee information 735a from the management device 53 or the display device 55 via the communication unit 733. In this case, the fee information 735a may not be stored in the recording unit 735 of the user terminal 73.

[0152] (About display of price information)

[0153] Fig.12 1 is a diagram showing an example of a price display screen 630 displayed on the user terminal 73 according to the embodiment. Here, differences from the price display screen 610 according to the first embodiment will be mainly described.

[0154] like Fig.12 As shown, the price display screen 630 further includes an economical driving preferential display area 631. The economical driving preferential display area 631 is an area for displaying the second preferential price information. Here, the economical driving preferential display area 631 is an example of the second display area and the fourth display area.

[0155] exist Fig.12 In the example of , the second preferential price information is discount information corresponding to the level of economic driving. The second preferential price information is discount information for the case where the level of economic driving is LV1 and the case where the level is Lv2. Fig.12In the example of FIG. 1 , the second preferential price information shows that when the level of economic driving is LV1, it is a discount of 1.0 Indian rupees per kWh, and when it is Lv2, it is a discount of 3.0 Indian rupees per kWh. In this way, the second preferential price information can be displayed as a difference from the standard price.

[0156] In addition, if Fig.12 As shown, the price display screen 630 further includes a display area 633 for station information and a display area 635 for the time period to which the fee information 735a is applied.

[0157] In the station information display area 633, the name of the charging station is displayed, such as "Station AAA", but geographical information and arrival time information calculated based on the current position may also be displayed. That is, the price display screen 630 is information for each charging station.

[0158] In the display area 635, the time period to which the fee information 735a is applied is displayed, such as "14:00-16:00". That is, the price display screen 630 is information for each time period. In addition, presenting the time period to which the discount can be applied may become a method of optimizing the battery replacement (demand amount) and the charging (supply amount) of the replaceable battery 9 at the charging station. In other words, by displaying the time period to which the fee information 735a is applied, it is possible to suppress the shortage of the replaceable battery 9 at the charging station, and to suppress the deterioration of the replaceable battery 9 caused by fast charging.

[0159] In addition, in the price display screen 630, Figure 7 Similarly, the discount information on the price display screen 620 may be information for displaying the standard price after the discount (offer) is applied, that is, the discounted replacement fee.

[0160] Fig.13 This is a flowchart showing an example of the flow of price display processing executed in the user terminal 73 according to the embodiment.

[0161] The control unit 731 acquires current time information, and selects a time period based on the acquired time information ( S201 ).

[0162] The control unit 731 acquires the fee information 735 a applied in the time period selected for the designated charging station from the recording unit 735 , for example, in response to a request (operation input) from the user 7 ( S202 ).

[0163] The control unit 731 acquires the battery type and remaining power (battery information 735c) of the replaceable battery 9 mounted on the electric car 71 from the recording unit 735 (S203).

[0164] The following description will be continued assuming that the surplus power acquired in the process of S203 is 20% or more.

[0165] The control unit 731 acquires the driving LV information 735b from the recording unit 735. Then, the control unit 731 determines the current level of economic driving based on the information on the overload during driving of the electric vehicle 71 using the power from the replaceable battery 9 before replacement (S204).

[0166] As an example, the level of economical driving is assumed to be set to two stages, Lv1 and Lv2. In addition, the information related to overload is assumed to be the number of sudden starts and / or sudden decelerations. In addition, the level of economical driving may be set to a plurality of stages of three or more.

[0167] As an example, if the number of sudden starts and / or sudden decelerations is less than 10 times, the control unit 731 determines that it is LV2, if it is less than 20 times, the control unit 731 determines that it is LV1, and if it is more than 20 times, the control unit 731 determines that no level is assigned, that is, it is not within the application of the economic driving benefit. In addition, the threshold value of the number of sudden starts and / or sudden decelerations is an example and can be set arbitrarily.

[0168] The following description will be continued assuming that the level of economical driving determined in the process of S204 is LV1.

[0169] The control unit 731 determines the display mode of the fee area (S205). Specifically, the control unit 731 matches the battery type, remaining power, level of economical driving, and fee information 735a to determine the applicable fee. Then, the control unit 731 determines the display mode of each fee according to the determination result.

[0170] Furthermore, the control unit 731 displays the price display screen 630 in the display format of the determined fee area (S206).

[0171] Moreover, similarly to the battery replacement system 1 according to each of the above-described embodiments, it is also possible to determine the level of economical driving and calculate a fee based on the level of economical driving when issuing a receipt.

[0172] Here, the fee area refers to the area including the standard price display area 613, the remaining power discount display area 615, and the economic driving discount display area 631. In addition, the display method refers to the color, font type, bold format, or flashing of the display when displaying each fee. Fig.12 In the example of , a change in bold (emphasized display) is shown as a change in the display method.

[0173] exist Fig.12In the example of FIG. 6 , the prices of the battery types A and B are displayed in bold in the standard price display area 613. In addition, the price of type C is displayed in a normal display manner. Thus, the price display screen 630 shows that the battery types A and B can be installed in the electric car 71 of the user 7.

[0174] exist Fig.12 In the example, the price of surplus power of 20% or more is displayed in bold in the surplus power discount display area 615. Thus, the price display screen 630 shows that when the replaceable storage battery 9 is replaced at the current time point, the discount for surplus power of 20% or more, i.e., a discount of 2.0 Indian rupees per kWh, can be applied.

[0175] exist Fig.12 In the example of FIG. 6 , the cost of the LV1 economic driving level is displayed in bold in the economic driving discount display area 631. Thus, the price display screen 630 shows that when the replaceable storage battery 9 is replaced at the current time point, the discount for the economic driving level LV1, that is, a discount of 1.0 Indian rupees per kWh, can be applied.

[0176] As described above, in the battery replacement system 1 according to the embodiment, the user terminal 73 is configured to display prices including not only the remaining power level of the replaceable battery 9 before replacement but also discount information corresponding to the level of economical driving.

[0177] According to this configuration, a price display that rewards battery-friendly usage can be performed, thereby guiding the driver to a driving style that reduces overloading of the replaceable battery 9. Reducing overloading of the replaceable battery 9 suppresses battery degradation and helps reduce the asset value of the replaceable battery 9.

[0178] In addition, even when the fee information applied is different for each charging station or each time period, the user 7 can know the applicable fees and discounts in real time. That is, according to the battery replacement system 1 involved in the embodiment, the user 7 can increase the motivation for economical driving.

[0179] Furthermore, each process according to each of the above-described embodiments may be implemented by distributed processing performed by a plurality of devices. For example, the management device 53 and the display device 55 may each be configured by a combination of a plurality of devices.

[0180] In the battery replacement system 1 according to each of the above-described embodiments, the management device 53 and the display device 55 may be integrally configured. For example, the display device 55 may be a part of the output unit 537 of the management device 53.

[0181] In each of the control units 531, 551, and 731 involved in the above-mentioned embodiments, various processors such as a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an ASIC (Application Specific Integrated Circuit), and a FPGA (Field Programmable Gate Array) can be appropriately utilized as a processor.

[0182] The communication units 533, 553, and 733 involved in the above-mentioned embodiments can respectively appropriately use a communication circuit for wired communication, a communication circuit for wireless communication, and a combination thereof as a hardware structure. As a communication circuit for wireless communication, a communication circuit corresponding to various standards such as 4G, 5G, 6G, Wi-Fi (registered trademark), Bluetooth (registered trademark), and infrared communication can be appropriately used.

[0183] The management device 53, the display device 55, and the user terminal 73 involved in each of the above-mentioned embodiments may be configured to be able to access the database for storing the fee information 555a, 735a via a computer-readable recording medium or a removable external storage device. As the computer-readable recording medium, for example, a CD-ROM, a floppy disk (FD), a CD-R, a DVD (Digital Versatile Disk), etc. can be used appropriately. In addition, as the removable external storage device, an HDD, an SSD, a flash memory, etc. can be used appropriately.

[0184] The program executed by each device of the battery replacement system 1 according to each embodiment described above is provided as an installable or executable file recorded in a computer-readable recording medium such as a CD-ROM, FD, CD-R, or DVD.

[0185] In addition, the program executed by each device of the battery replacement system 1 according to each of the above-mentioned embodiments may be stored on a computer connected to a network such as the Internet, and provided by downloading via the network. In addition, the program executed by each device of the battery replacement system 1 according to each of the above-mentioned embodiments may be provided or distributed via a network such as the Internet.

[0186] In addition, a configuration may be adopted in which a program executed by each device of the battery replacement system 1 according to each of the above-described embodiments is installed in advance in a ROM or the like and provided.

[0187] According to at least one of the embodiments described above, it is possible to suppress a decrease in the asset value of the replaceable storage battery.
