[0017] Hereinafter, embodiments of a use management assistance method, a use management assistance device, an assistance system, a program, and a storage medium to which the present disclosure is applied will be described with reference to the accompanying drawings.

[0018] Further, in the description of the present disclosure, with respect to a structural element having the same or substantially the same function as that of a structural element described above with respect to a figure already appearing, the same reference sign is sometimes annotated and the description is appropriately omitted. In addition, even in the case of indicating the same or substantially the same portion, sometimes the size, the scale of each other is represented differently depending on the figure. In addition, for example, from the viewpoint of securing the visual confirmation of the figure, sometimes only the main structural element is annotated with the reference sign in the description of each figure, and even a structural element having the same or substantially the same function as that of the structural element described above in the figure already appearing is not annotated with the reference sign.

[0019] In the past, in a traffic operator, a logistics operator, a rental car operator, or the like, an electric vehicle capable of traveling using electric power from a storage battery mounted on an electric car, a hybrid car, or the like is held or rented, and a use management business for managing the use thereof is performed.

[0020] ​​Generally, in a storage battery, degradation such as a decrease in maximum capacity occurs due to various factors such as a use state of, for example, an input / output current value, a number of times of charging and discharging, a distance of travel of a mounted electric vehicle, a use environment at the time of charging and discharging, or a number of years elapsed from the manufacture. In addition, generally, in a storage battery, a quality sometimes varies depending on, for example, a manufacturing period, a manufacturing site, or a manufacturing operator. Accordingly, in the operation management of an electric vehicle, a storage battery performance such as a degree of degradation of a mounted storage battery or a quality is valued.

[0021] For example, there is a technology in which a degree of degradation of a secondary battery of a host vehicle is compared with that of a storage battery of the same kind or a storage battery of the same kind mounted in the same vehicle model, whereby a use state of the storage battery can be objectively viewed, and an appropriate use method of the storage battery can be displayed in accordance with the use state. In the above technology, for the purpose of involving a driver in improvement of his or her own travel, regarding a single electric vehicle held as an owner car, the electric vehicle is provided with performance information of a storage battery to the driver.

[0022] Among the operators, a traffic operator, a logistics operator, a rental car operator, or the like sometimes manages a plurality of electric vehicles of a plurality of vehicle models held as fleet cars or the like. Therefore, for example, if the use of judgment material at the time of additional introduction such as an increase in the number of electric vehicles or additional rental by an operator who manages the operation of electric vehicles is taken into consideration, performance information indicating a storage battery performance is preferably information according to an operation mode of each operator.

[0023] However, in the comparison with a storage battery of the same kind or a storage battery of the same kind mounted in the same vehicle model, there is a problem that information based on a comparison of storage battery performances of a group of vehicle models as such vehicle models cannot be provided as performance information indicating a storage battery performance. In addition, there is a problem that a way of providing performance information indicating a storage battery performance on the vehicle side is not suitable for a request in a business of operation management in which a comparison of storage battery performances of a group of vehicle models is desired. Thus, there is room for improvement in performance information of a storage battery for presentation to an operator who performs a business of operation management of an electric vehicle, and a way of providing the same.

[0024] Therefore, in the present disclosure, one of the objects is to provide performance information of a storage battery that assists a management service for managing use of an electric vehicle equipped with the storage battery. For example, an object of at least one embodiment of the present disclosure is to provide performance information of a storage battery that becomes a material for judgment when an operator who manages a plurality of vehicles of a plurality of vehicle types adds an electric vehicle. For example, an object of at least one embodiment of the present disclosure is to provide information on a running pattern for each operator as performance information of a storage battery. For example, one of the objects of at least one embodiment of the present disclosure is to provide a user interface system that enables an operator who holds an electric vehicle equipped with a storage battery to easily grasp a vehicle type in which the storage battery has good performance.

[0025] Figure 1 is a diagram illustrating an example of a structure of an assistance system 1 according to an embodiment. As Figure 1 indicated, the assistance system 1 includes a management device 10, a fleet 20, and a server 40. The management device 10 and the server 40 are communicably connected via a network N, for example. As the network N, an electric communication line such as the Internet can be used, for example.

[0026] The assistance system 1 is configured to provide, for an operator such as a transportation operator, a logistics operator, or a rental car operator who uses the assistance system 1, an assistance service that assists a management service for managing a fleet 20 including a plurality of electric vehicles of a plurality of vehicle types. The assistance service provides, for the using operator, performance information of a storage battery that assists the management service.

[0027] As an example, the assistance system 1 can be configured as a server-client type system including the server 40 and the management device 10 as a client device. As the management device 10, various computers such as a smartphone, a personal computer (PC), a tablet PC, or a car navigation system can be appropriately used. As the server 40, various computers such as a server device or a PC can be appropriately used.

[0028] The management device 10 is, for example, a device that is used by an operator who uses an assistance service of the assistance system 1 and that is used to assist a management service thereof. The management device 10 is configured to be able to execute an assistance process on the client side according to an embodiment. Here, the management device 10 according to an embodiment is an example of a use management assistance device.

[0029] The fleet 20 includes a plurality of vehicles 30 of a plurality of vehicle types that are possessed or rented and managed by an operator who utilizes the assistance system 1. The plurality of vehicles 30 are each, for example, an electric vehicle, a hybrid vehicle, or the like that utilizes a storage battery. The storage battery is, for example, a secondary battery that accumulates electric power supplied from an external commercial power source or the like or regenerated electric power and discharges electric power for driving the vehicle 30.

[0030] Further, as the storage battery, various secondary batteries such as a lead storage battery, a lithium ion battery, a nickel-hydrogen battery, a nickel-cadmium battery, and an all-solid-state battery can be appropriately utilized. In addition, as the vehicle 30, as long as it is an electric vehicle that is driven using electric power from a mounted storage battery, a bicycle, a motorcycle, a passenger vehicle of three or more wheels, another automobile such as a truck, a scooter, or the like can be appropriately utilized.

[0031] Further, Figure 1 A first vehicle 30-1 of a first vehicle type, a second vehicle 30-2 of a second vehicle type, and a third vehicle 30-3 of a third vehicle type are exemplified, but are not limited thereto. In the present disclosure, the fleet 20 can be composed of one or two vehicle types, or can be composed of four or more vehicle types. In addition, the number of vehicles 30 of each vehicle type is also arbitrary, and can be one, or two or more.

[0032] The server 40 is a device that is utilized by an operator who provides an assistance service of the assistance system 1 and assists an operation management business of a user of the assistance service. The server 40 is configured to be able to execute an assistance process on the server side involved in the embodiments.

[0033] Further, in the assistance system 1 involved in the present disclosure, a part of the functions of the management device 10 can also be realized by the server 40. At this time, the management device 10 can also be configured as a device that receives input of battery information of the storage battery by the operator, an operation for designating an analysis target, an operation of changing a display content, and the like, and displays at least one display screen for displaying performance information of the storage battery on a Web browser or an application.

[0034] Figure 2 is a drawing that shows an example of a hardware structure of each device (for example, the management device 10 and the server 40) of the assistance system 1 involved in the embodiments.

[0035] As Figure 2 indicated, each device of the assistance system 1 has a processor 51, a memory 52, an HMI 53, and a communication I / F (interface) 56. The HMI 53 has a display 54 and an input I / F 55. The processor 51, the memory 52, the display 54, the input I / F 55, and the communication I / F 56 are connected to each other by a bus 59 or the like, and become a hardware structure that utilizes a general-purpose computer.

[0036] The processor 51 is an arithmetic device that controls the entire auxiliary system 1. The processor 51 realizes each process described below, for example, by loading a program stored in a ROM (Read Only Memory) or the like of the memory 52 into a RAM (Random Access Memory) and executing the program.

[0037] Further, the processor 51 according to the embodiment can appropriately use various processors such as a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), a DSP (Digital Signal Processor), a dedicated arithmetic circuit realized by an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array), and the like.

[0038] The memory 52 stores programs, parameters, and the like for realizing various processes of the processor 51. For example, the memory 52 is a main storage device of each device of the auxiliary system 1, and includes a RAM that temporarily stores data required for various processes of the processor 51. For example, the memory 52 includes a ROM, an HDD (Hard Disk Drive), an SSD (Solid State Drive), various storage media such as a flash memory, and a storage device that store various data, programs, and the like used in each device of the auxiliary system 1.

[0039] The display 54 is an example of an output I / F of the HMI 53. The display 54 is configured to be able to output an image, a video, and the like. The display 54 is, for example, an LCD (Liquid Crystal Display) or an organic EL (Electro Luminescence) display. Further, the display 54 can be configured as a touch panel display. Here, the display 54 of the management device 10 according to the embodiment is an example of a display section.

[0040] The input I / F 55 is realized as a touch panel of the display 54 configured as a touch panel display, for example. Further, the input I / F 55 can include other input I / F such as a keyboard, a mouse, a button, a dial, a switch, a microphone, and the like. Here, the input I / F 55 of the management device 10 according to the embodiment is an example of an acquisition section.

[0041] Further, as the HMI 53, a tablet terminal, a smartphone, a smartwatch, a remote controller, or the like that can transmit or receive a signal from the outside of each device can also be utilized.

[0042] Further, the HMI 53 can also not be provided in the server 40.

[0043] The communication I / F 56 is an interface for transmitting and receiving data. For example, as the communication I / F 56, a communication circuit for wired communication, a communication circuit for wireless communication, and a combination thereof can be appropriately utilized. As the communication circuit for wireless communication, a communication circuit corresponding to various standards such as 3G, 4G, Wi-Fi (registered trademark), Bluetooth (registered trademark), and the like can be appropriately utilized.

[0044] Figure 3 is a diagram illustrating an example of a functional structure of the management device 10 according to the embodiment. The management device 10 realizes the functions as the acquisition section 11, the analysis section 12, the display section 13, and the storage section 14 by the processor 51 executing a program loaded to the memory 52.

[0045] The acquisition section 11, for example, accepts designation of an analysis target in the analysis screen based on an output of the input I / F 55 corresponding to a user operation (refer to Figure 6 ). In addition, the acquisition section 11 acquires battery information of a vehicle model that is the designated analysis target.

[0046] As an example, the acquisition section 11 acquires battery information of a vehicle model that is the designated analysis target, which is included in battery information of a management target vehicle that is a vehicle 30 managed by an operator who operates the management device 10. Here, the battery information of the vehicle model that is the designated analysis target is an example of the first battery information.

[0047] Here, in the battery information of the management target vehicle, with respect to each vehicle 30 in at least one vehicle 30 that is a management target, for example, a value of a travel distance and a value of a maximum capacity of a storage battery can also be included. The battery information of the management target vehicle is stored in the storage section 14 of the management device 10, for example, but can also be stored in the accumulation section 42 of the server 40 or the like outside the management device 10.

[0048] Further, in the battery information of the management target vehicle, a value of a decrease amount of the maximum capacity of the storage battery per distance traveled of each vehicle 30 of the at least one vehicle 30 that is a management target can also be included. In addition, in the battery information of the management target vehicle, an average value of the value of the decrease amount of the maximum capacity per distance traveled of each vehicle type of the at least one vehicle 30 that is a management target can also be included. This average value is an example of the first evaluation value that indicates a tendency of the deterioration speed of the storage battery performance of each vehicle type. In addition, in the battery information of the management target vehicle, a value of the standard deviation of the first evaluation value of each vehicle type of the at least one vehicle 30 that is a management target can also be included. This value of the standard deviation is an example of the third evaluation value that indicates a tendency of the deviation of the storage battery performance of each vehicle type.

[0049] As an example, the acquisition section 11 acquires the battery information of the vehicle type group accumulated by the operator of the operation server 40. Here, the battery information of the vehicle type group is an example of the second battery information.

[0050] Here, in the battery information of the vehicle type group, for example, the first evaluation value that indicates a tendency of the deterioration speed of the storage battery performance and the third evaluation value that indicates a tendency of the deviation of the storage battery performance after being standardized throughout the entirety of the vehicle type group registered to the assistance system 1 can also be included. The battery information of the vehicle type group is stored in the accumulation section 42 of the server 40, for example, but a part thereof can also be stored in the storage section 14 or the like of the management device 10 inside the management device 10.

[0051] Further, in the battery information of the vehicle type group, for example, a value of the maximum capacity of the storage battery per distance traveled of each vehicle 30 of the at least one vehicle 30 registered to the assistance system 1, a value of the decrease amount of the maximum capacity of the storage battery per distance traveled can also be included.

[0052] In addition, the acquisition section 11 accepts designation of the threshold value of the abnormality rate in the analysis screen based on the output of the input I / F 55 corresponding to the user operation, for example (refer to FIG. 6). Figure 7 ).

[0053] The analysis section 12 analyzes the battery information of the vehicle type that is a designated analysis target based on the battery information acquired by the acquisition section 11.

[0054] As an example, the analysis section 12 calculates, with respect to each vehicle 30 of the at least one vehicle 30 of the management target vehicle that is a designated analysis target, a value of the decrease amount of the maximum capacity per distance traveled based on the value of the distance traveled and the value of the maximum capacity of the storage battery included in the battery information of the management target vehicle. In addition, the analysis section 12 calculates, with respect to the at least one vehicle 30 of the management target vehicle of the vehicle type that is a designated analysis target, an average value of the value of the decrease amount of the maximum capacity per distance traveled as the first evaluation value that indicates a tendency of the deterioration speed of the storage battery performance.

[0055] As an example, the analysis section 12 calculates a second evaluation value indicating the degree of the rate of deterioration of the performance of the storage battery by comparing the first evaluation value calculated from the battery information of the management target vehicle with the standardized first evaluation value included in the battery information of the vehicle type group. For example, the analysis section 12 calculates a score indicating the magnitude of the first evaluation value calculated from the battery information of the management target vehicle with the standardized first evaluation value as a reference as the second evaluation value. For example, there can be a manner in which the second evaluation value is set to a score of 30 points or less, or to a score lower than 50 points, in a case where the first evaluation value calculated from the battery information of the management target vehicle is greater than the standardized first evaluation value. Alternatively, there can be a manner in which the second evaluation value is set to a score of 70 points or more, or to a score higher than 50 points, in a case where the first evaluation value calculated from the battery information of the management target vehicle is less than the standardized first evaluation value.

[0056] As an example, the analysis section 12 calculates a standard deviation of the values of the amount of decrease in the maximum capacity per travel distance of at least one vehicle 30 of the vehicle type group that is designated as the analysis target in the management target vehicle as a third evaluation value indicating the tendency of the deviation of the performance of the storage battery.

[0057] As an example, the analysis section 12 calculates a fourth evaluation value indicating the degree of the deviation of the performance of the storage battery by comparing the third evaluation value calculated from the battery information of the management target vehicle with the standardized third evaluation value included in the battery information of the vehicle type group. For example, the analysis section 12 calculates a score indicating the magnitude of the third evaluation value calculated from the battery information of the management target vehicle with the standardized third evaluation value as a reference as the fourth evaluation value. For example, there can be a manner in which the fourth evaluation value is set to a score of 30 points or less, or to a score lower than 50 points, in a case where the third evaluation value calculated from the battery information of the management target vehicle is greater than the standardized third evaluation value. Alternatively, there can be a manner in which the fourth evaluation value is set to a score of 70 points or more, or to a score higher than 50 points, in a case where the third evaluation value calculated from the battery information of the management target vehicle is less than the standardized third evaluation value.

[0058] As an example, the analysis section 12 calculates a fifth evaluation value indicating the degree of the abnormality rate of the battery performance, with respect to at least one vehicle 30 of the vehicle type designated as the analysis target, based on the value of the respective travel distances, the value of the maximum capacity of the respective batteries, and the threshold value of the designated abnormality rate. For example, the fifth evaluation value is at least any one of information indicating the number of the vehicles 30 lower than the threshold value of the designated abnormality rate, and the proportion thereof, with respect to the number of at least one vehicle 30 of the vehicle type designated as the analysis target among the management target vehicles.

[0059] Further, each of the above-described evaluation values is not limited to the average value and the standard deviation, and other statistical values such as the central value and the variance can be used for the calculation.

[0060] The display section 13 displays an analysis screen for designating the analysis target, for example, through the display 54 of the management device 10. In addition, the display section 13 displays an analysis screen for displaying the evaluation result based on the analysis of the analysis section 12, through the display 54 of the management device 10. Here, the display section 13 related to the embodiment is an example of the output section.

[0061] The storage section 14 is realized, for example, by the storage 52 of the management device 10. The storage section 14 stores the battery information of the above-described management target vehicles.

[0062] Further, a part of the functions of the management device 10 related to the embodiment can also be realized outside the management device 10 such as a server device provided separately from the assistance system 1 and communicable with the management device 10 via the network N.

[0063] Figure 4 is a diagram showing an example of the functional structure of the server 40 related to the embodiment. The server 40 realizes the functions as the information management section 41 and the accumulation section 42 by the processor 51 executing the program loaded to the storage 52.

[0064] The information management section 41 reads out the battery information of the vehicle type corresponding to the request from the management device 10 from the accumulation section 42. In addition, the information management section 41 outputs the battery information read out from the accumulation section 42 to the management device 10.

[0065] The accumulation section 42 is realized, for example, by the storage 52 of the server 40. The accumulation section 42 stores the battery information by vehicle type related to at least one vehicle type registered to the above-described assistance system 1.

[0066] Next, the flow of the process performed by the assistance system 1 configured as described above will be described. Figure 5 is a flowchart showing an example of the flow of the assistance process performed by the management device 10 related to the embodiment.

[0067] First, the display unit 13 displays the analysis screen via the display 54 (S1). Figure 6 It is shown in Figure 5 The image shows an example of a display screen 610 during the processing. Figure 6 The display screen 610 exemplifies an analysis screen used to specify an analysis object in the management device 10. As an example, the display screen 610 includes a first display area 601 and a second display area 603. The first display area 601 and the second display area 603 are respectively areas used to display analysis results regarding the battery performance of the specified vehicle model, that is, evaluation results based on comparison with the battery information of the accumulated vehicle model group.

[0068] An operation unit for specifying the analysis object is provided in the first display area 601 and the second display area 603 respectively. Figure 6 In the example, the first display area 601 includes a group selection bar 701, a vehicle model selection bar 703, and an analysis date selection bar 705. Similarly, the second display area 603 includes a group selection bar 801, a vehicle model selection bar 803, and an analysis date selection bar 805.

[0069] The group selection fields 701 and 801 are used to select at least one group from the partitions of vehicles 30 managed by the operator utilizing the ancillary services, and display the group as the object of analysis. Here, a group refers to the management partition of the vehicle 30 of the operator utilizing the ancillary services, such as partitions like "Branch Office" or "Office".

[0070] The vehicle selection columns 703 and 803 are used to select at least one vehicle model from at least one vehicle 30 belonging to the selected group as the model to be analyzed.

[0071] The selection fields 705 and 805 for the analysis object day are used to display the period for selecting the analysis object. Here, the analysis object day can be a partition such as current, past, or all, or a partition based on year, month, or week, or a partition that specifies the start and end points by date.

[0072] In addition, Figure 6 In this context, the operation section used to specify the object to be analyzed is not limited to a selection bar for choosing from pre-registered candidates, but can also be an input bar for direct user input.

[0073] Furthermore, operation units for instructing the execution of analysis are respectively provided in the first display area 601 and the second display area 603. This analysis is for obtaining evaluation results related to a specified analysis object. Figure 6In the example of FIG. 6, the first display area 601 includes the operation button 707 for instructing execution of the analysis. Likewise, the second display area 603 includes the operation button 807 for instructing execution of the analysis.

[0074] Next, the acquisition section 11 determines whether the analysis target is specified (S2). As an example, the acquisition section 11 determines whether the operation button 707, 807 for instructing execution of the analysis of the battery performance in the display screen 610 is operated based on the output of the input I / F 55 corresponding to the user operation. For example, in a case where the operation button 707, 807 is operated, the acquisition section 11 determines that the analysis target is specified.

[0075] In a case where the analysis target is not specified (S2: No), Figure 5 The flow of the process of FIG. 6 proceeds to the process of S7.

[0076] On the other hand, in a case where the analysis target is specified (S2: Yes), the acquisition section 11 receives the specification of the analysis target (S3). As an example, the acquisition section 11 receives the operation result of the operation section for specifying the analysis target in the display screen 610 as the analysis screen based on the output of the input I / F 55 corresponding to the user operation. For example, in a case where the operation button 707, 807 of the first display area 601 is operated, the acquisition section 11 receives the specification of the analysis target by the selection of the bar 701, 703, 705. Likewise, in a case where the operation button 807 of the second display area 603 is operated, the acquisition section 11 receives the specification of the analysis target by the selection of the bar 801, 803, 805.

[0077] In addition, the acquisition section 11 acquires the battery information of the vehicle model as the specified analysis target and the battery information of the standardized vehicle model group (S4). As an example, the acquisition section 11 acquires the battery information of the vehicle 30 as the management target corresponding to the received specification of the analysis target from the storage section 14. In addition, the acquisition section 11 requests the server 40 for the battery information of the vehicle model group. At this time, the information management section 41 of the server 40 reads out the battery information of the vehicle model group from the accumulation section 42 according to the request from the management device 10 and outputs the battery information of the vehicle model group to the management device 10. Then, the acquisition section 11 of the management device 10 acquires the battery information of the vehicle model group from the server 40.

[0078] The analysis unit 12 analyzes battery performance based on the acquired battery information (S5). As an example, the analysis unit 12 calculates evaluation values ​​related to battery performance by analyzing battery information of the vehicle model designated as the analysis object and standardized battery information of the vehicle model group. The evaluation values ​​related to battery performance include at least one of the following: a first evaluation value indicating a trend in the rate of degradation, a second evaluation value indicating the degree of degradation, a third evaluation value indicating a trend in deviation, a fourth evaluation value indicating the degree of deviation, and a fifth evaluation value indicating the degree of abnormality.

[0079] The display unit 13 displays the evaluation results of the battery performance of each vehicle model based on the analysis of the analysis unit 12 on the analysis screen (S6). Figure 7 It is shown in Figure 5 The image shows an example of a display screen 620 during the processing. Figure 7 The display screen, 620 examples, shows an analysis screen displaying the evaluation results of the battery performance for each vehicle model based on analysis. As an example, Figure 7 The display screen 620 and Figure 6 The display screen 610 also includes a first display area 601 and a second display area 603. Figure 7 The display screen shows 620 examples. Figure 6 The display screen 610 shows the analysis screen when evaluation results 711 and 811 are displayed.

[0080] exist Figure 7 The first display area 601 of the display screen 620 displays the current evaluation result 711 for "Model B1" of "Group A1" specified by selection bars 701, 703, and 705. Similarly, the second display area 603 displays the current evaluation result 811 for "Model B2" of "Group A2" specified by selection bars 801, 803, and 805.

[0081] In addition, Figure 7 In the display screen 620, the evaluation results 711 and 811 are displayed including a scatter plot. This scatter plot represents the battery performance of each of the at least one vehicle 30 designated as the analysis object, with the driving distance and maximum battery capacity as the horizontal and vertical axes, respectively, as plotted as graphs 713 and 813. Based on this scatter plot display, the user can gain a top-down view of the battery performance of the analyzed vehicle 30, or make comparisons between different vehicle models.

[0082] In addition, Figure 7In display screen 620, the first evaluation value, representing the trend of the rate of degradation of battery performance, is displayed on a scatter plot using line graphs 715 and 815, where the slope of the value represents its magnitude. Figure 7 In the example, the display of 715 and 815 indicates that the higher the first evaluation value, the steeper the slope and the faster the degradation. Based on the display of this first evaluation value of 715 and 815, users can intuitively grasp the magnitude of the degradation rate or make comparisons between models being compared.

[0083] In addition, Figure 7 In display screen 620, a second evaluation value indicating the rate of degradation of battery performance is represented by displays 721 and 821, which use numerical values ​​and icons to represent this value. Figure 7 In the example, 721 and 821 indicate that a higher second evaluation value means a lower score and a faster rate of degradation. Furthermore, 721 and 821 can be displayed as either numerical values ​​or icons. Based on the displayed scores of 721 and 821 for this second evaluation value, users can quantitatively assess the rate of degradation or make comparisons between different car models. Additionally, based on the icon display, users can qualitatively assess the rate of degradation or make comparisons between different car models.

[0084] In addition, Figure 7 In the display screen 620, the third evaluation value, which indicates the trend of deviation in battery performance, can also be represented as the width (thickness) of, for example, the display 715, 815 of the first evaluation value. For example, the larger the third evaluation value, the thicker the display 715, 815 becomes. According to this structure, the user can intuitively grasp the magnitude of the deviation or make comparisons between vehicle models used as comparison objects.

[0085] In addition, Figure 7 In display screen 620, the fourth evaluation value, indicating the degree of deviation in battery performance, is represented by displays 723 and 823, which use numerical values ​​and icons to represent this value. Figure 7 In the example, the display of 723 and 823 indicates that the higher the fourth evaluation value, the lower the score and the greater the deviation. Furthermore, the display of 723 and 823 can be either a numerical value or an icon. Based on the displayed score of 723 or 823 for the fourth evaluation value, users can quantitatively grasp the magnitude of the deviation or make comparisons between models being compared. Additionally, based on the icon display, users can qualitatively grasp the magnitude of the deviation or make comparisons between models being compared.

[0086] In addition, Figure 7In the display screen 620, the display of the scatter diagram of the evaluation result 711, 811 includes the display of the threshold bar 717, 817 as the operation bar for designating the threshold of the abnormality rate. The display of the threshold bar 717 includes the display of the threshold bar 717a, 717b. The threshold bar 717a is the operation icon for designating the threshold of the travel distance of the horizontal axis with respect to the scatter diagram of the evaluation result 711 displayed in the first display region 601. The threshold bar 717b is the operation icon for designating the threshold of the maximum capacity of the vertical axis with respect to the scatter diagram of the evaluation result 711 displayed in the first display region 601. The display of the threshold bar 817 includes the display of the threshold bar 817a, 817b. The threshold bar 817a is the operation icon for designating the threshold of the travel distance of the horizontal axis with respect to the scatter diagram of the evaluation result 811 displayed in the second display region 603. The threshold bar 817b is the operation icon for designating the threshold of the maximum capacity of the vertical axis with respect to the scatter diagram of the evaluation result 811 displayed in the second display region 603. Further, the display of the threshold bar 717, 817 can also be used to designate at least one of the threshold of the travel distance and the threshold of the maximum capacity. That is, as the threshold of the abnormality rate, a threshold related to at least one of the travel distance and the maximum capacity can also be designated.

[0087] Further, in the display screen 620, Figure 7 In the display screen 620, with respect to each plot 713, 813 of the scatter diagram, the plot 713a, 813a satisfying the threshold of the abnormality rate designated by the threshold bar 717, 817 and the plot 713b, 813b lower than the threshold can also be represented in a manner that can be visually distinguished. Further, in the display screen 620, Figure 5 In the display screen 620, in the scatter diagram, a region lower than the threshold of the abnormality rate designated by the threshold bar 717, 817 can also be represented in a manner that can be visually distinguished.

[0088] Further, in the display screen 620, Figure 5 In the display screen 620, a fifth evaluation value indicating the degree of the abnormality rate of the battery performance is represented by the display 725, 825 of the number of the vehicle 30 lower than the threshold of the abnormality rate designated and the proportion thereof with respect to the number of the vehicle 30 of the vehicle model as the analysis target in the management target vehicle. Further, the display 725, 825 can also be either one of the number of the vehicle 30 lower than the threshold and the proportion thereof. According to the display of the display 725, 825 of the fifth evaluation value, the user can quantitatively grasp the number, the proportion of the vehicle 30 lower than the threshold of the abnormality rate designated or compare between the vehicle models as the comparison target. Further, the fifth evaluation value can also be defined using the normal rate instead of the abnormality rate.

[0089] Here, again referring to Figure 5The process of auxiliary processing performed by the management device 10 according to the embodiment will continue to be described.

[0090] The acquisition unit 11 determines whether the threshold bar 817 has been operated (S7). As an example, the acquisition unit 11 determines whether the threshold bars 717 and 817 used to specify the threshold of the abnormal rate in the display screen 620 have been operated based on the output of the input I / F 55 corresponding to the user operation.

[0091] If threshold bar 817 is not operated on (S7: "No"), Figure 5 The process then proceeds to S9 for processing.

[0092] On the other hand, if the threshold bar 817 is operated (S7: "Yes"), the acquisition unit 11 accepts the change of the threshold of the abnormal rate and updates the display of the evaluation results in the analysis screen according to the changed threshold of the abnormal rate (S8).

[0093] Then, the acquisition unit 11 determines, for example, whether to end the battery performance evaluation based on the output of the input I / F 55 corresponding to the user operation. Figure 5 Auxiliary processing (S9). If the process does not terminate (S9: "No"), ​ The process returns to step S2. In the case of completion (S9: "Yes"), the display unit 13 ends the display of the analysis screen on the display 54. Afterwards, ​ The process is complete.

[0094] Furthermore, regarding the auxiliary processing involved in this embodiment, the first display area 601 and the second display area 603 are configured to independently display the evaluation results of the battery performance. Therefore, in the first display area 601 and the second display area 603, different evaluation results of either of the primarily specified analytical objects can be displayed in a comparative manner for comparison, but evaluation results for the same analytical object can also be displayed. For example, when displaying evaluation results for the same analytical object, the abnormal rate under different threshold conditions can also be displayed in a comparative manner.

[0095] In addition, when the evaluation results are calculated and displayed in either the first display area 601 or the second display area 603, and the analysis object is specified or changed for the other side and the analysis is instructed, the display scale of the scatter plot of the other side can also be changed in conjunction with the display of the new evaluation results.

[0096] Further, the analysis screen is not limited to the two display regions of the first display region 601 and the second display region 603, and can have three or more display regions. In addition, the first display region 601 and the second display region 603 are not limited to being arranged in the up-and-down direction, and can be arranged in the left-and-right direction. In addition, the first display region 601 and the second display region 603 are not limited to being arranged, and can be configured as one display region by being displayed in an overlapping manner or the like. For example, the analysis screen can be a display screen in which two or more vehicle models that are comparison targets are displayed by one scatter plot. In addition, for example, in the analysis screen, each evaluation value regarding two or more vehicle models that are comparison targets can be collectively displayed in one display region. Alternatively, in the analysis screen, a statistical value such as a difference value, an average value, or the like of each evaluation value regarding two or more vehicle models that are comparison targets can be displayed instead of or in addition to each evaluation value.

[0097] Further, in the analysis screen, the scatter plot can take the maximum capacity on the horizontal axis and the travel distance on the vertical axis. In addition, instead of the travel distance, various parameters that have an influence on the deterioration of the storage battery, such as the elapsed years from the manufacture, the power consumption, the travel time, the charge amount, the charging time, and the charge / discharge frequency can be used.

[0098] In addition, in the analysis screen, the scatter plot is not necessarily a structure, and can not be displayed. For example, the analysis screen can be a display screen for displaying only the scores and the icons of each evaluation value. Alternatively, the analysis screen can be a display screen for displaying only the scatter plot and the first evaluation value. In this case, the acquisition unit 11 can acquire only the first battery information regarding the vehicle 30 that is the management target, and can not acquire the second battery information that is the battery information of the vehicle model group from the server 40. In addition, the analysis unit 12 can calculate the first evaluation value based only on the first battery information regarding the vehicle 30 that is the management target, and can not use the second battery information.

[0099] Further, the selection bar 705, 805 of the analysis target day can be configured to be able to specify a future such as a partition and a date in the future. Also, as the display of the evaluation result 711, 811, a scatter plot indicating the performance of the storage battery in the future and each evaluation value can be calculated and displayed. That is, regarding the evaluation result 711, 811, for example, by effectively using a deterioration prediction technique, each evaluation value such as a scatter plot, a score, or an icon in the future, such as one year later, five years later, or the like, can be displayed in addition to the result of the present situation. According to this structure, it is possible to provide evaluation information of the performance of the storage battery as a judgment material for discussing in advance the purchase or update of the vehicle 30 in the future, and to assist the operation management business.

[0100] Further, in the model selection field 703, 803, it is also possible to select a model that is not held by the operator who manages the operation of the electric vehicle as a model to be analyzed. Alternatively, an input field in which a model that is not held can be input as a model to be analyzed can be displayed. Also, as the display of the evaluation results 711, 811, a scatter diagram or each evaluation value that represents the evaluation results with respect to a model that is not held by the operator who manages the operation of the electric vehicle can be calculated and displayed. For example, a correction amount of battery information based on the performance difference of the battery performance between models can be set and stored in advance in the storage section 14 of the management device 10 or the accumulation section 42 of the server 40. In addition, for example, the analysis section 12 can correct the battery information of the vehicle 30 of a model held by the operator who manages the operation of the electric vehicle by using the correction amount, thereby calculating a scatter diagram or each evaluation value with respect to a model that is not held by the operator. According to this structure, it is possible to provide evaluation information of the battery performance as a judgment material for discussing the introduction of a model that is not held, in addition to the increase in the number of models held and the like, to assist the operation management business. In addition, according to the method of correcting the battery information of the vehicle 30 held, it is possible to simulate the evaluation results with respect to a model that is not held in a case where the same usage method as that of the vehicle 30 held is performed.

[0101] Further, the battery information of the vehicle 30 held by the operator can be automatically acquired at the time of charging and stored in the management device 10, for example, can be accepted by the input of the operator using the HMI 53, and can be acquired based on data obtained by scanning a paper medium such as a repair record book. As an example, the controller of the battery mounted on the vehicle 30 can be communicably connected to an in-vehicle network including a CAN (Controller Area Network), an Ethernet (registered trademark), or the like, for example. In addition, a computer such as an ECU (Electronic Control Unit) or an OBU (On Board Unit) provided in the interior of the vehicle 30 can be communicably connected to the controller of the mounted battery via the in-vehicle network, for example. In addition, for example, the computer can be communicably connected to the management device 10 or the server 40 via the network N. In addition, for example, the computer can output the battery information of the battery mounted on the vehicle 30 to the management device 10 or the server 40 via the network N or in a direct connection manner.

[0102] Further, the management device 10 according to the above-described embodiments can not have the display 54. That is, the management device 10 can be configured as a device that outputs the evaluation result 711, 811, display information for displaying an analysis screen including the evaluation result, to the outside. In this case, the processor 51 can be configured to realize an output section that outputs the display information, for example, by the communication I / F 56, instead of the display section 13.

[0103] Thus, in the assist system 1 according to the embodiments, the management device 10 is configured to acquire, with respect to any vehicle type managed by an operator of a use management business, battery information related to a storage battery mounted on at least one vehicle 30, and further acquire standardized battery information based on big data of battery information of vehicle type groups accumulated in the server 40. Further, the management device 10 is configured to calculate an evaluation value related to a battery performance of the storage battery by analysis of comparison of the acquired battery information, and output display information for displaying an evaluation result.

[0104] According to this configuration, it is possible to provide performance information of a storage battery that assists management of a use management business of mounted electric vehicles. For example, according to the above-described configuration, it is possible to provide performance information of a storage battery that becomes a material for judgment when an operator of a transportation operator, a logistics operator, a rental car operator, or the like adds an electric vehicle to manage a plurality of vehicles of a plurality of vehicle types. For example, according to the above-described configuration, it is possible to provide information of a running pattern for each operator as performance information of a storage battery. For example, according to the above-described configuration, it is possible to provide a user interface system that enables an operator who holds an electric vehicle mounted with a storage battery to easily grasp a vehicle type with good storage battery performance.

[0105] Further, in each of the above-described embodiments, "determining whether A" can be a case of determining A, a case of determining not A, or a case of determining whether A.

[0106] Each program executed by each device of the assist system 1 according to the above-described embodiments is recorded in a file in an installable format or an executable format on a computer-readable storage medium such as a CD-ROM, an FD, a CD-R, a DVD, or the like.

[0107] Further, each program executed by each device of the assist system 1 according to the above-described embodiments can be configured to be saved on a computer connected to a network such as the Internet and provided by download via the network. Further, each program executed by each device of the assist system 1 according to the above-described embodiments can be configured to be provided or distributed via a network such as the Internet.

[0108] Also, each program executed by each device of the assistance system 1 according to the above-described embodiments can be provided by being installed in advance in a ROM or the like.

[0109] Also, each program executed by each device of the assistance system 1 according to the above-described embodiments is a module structure including each functional section described above, and as actual hardware, the processor 51 such as a CPU reads the program from a memory 52 such as a ROM or a HDD and executes it, whereby each functional section described above is loaded on a RAM of the memory 52, and each functional section described above is generated on the RAM of the memory 52.

[0110] According to at least one embodiment described above, it is possible to provide evaluation information of a storage battery performance for assisting a management service for managing use of an electric vehicle equipped with a storage battery.

[0111] Several embodiments of the present application have been described above, but these embodiments are presented by way of example and are not intended to limit the scope of the application. These embodiments can be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the application.
