The control unit 31 can acquire a diagnosis result (diagnosis information) indicating the degree of degradation of the battery and the transaction price of the battery from the diagnosis information server 120 via the communication unit 32.

Since the simple diagnosis field terminal 30 is used by a serviceman in a 4S shop, a shared service, or the like to measure the battery remaining capacity of each battery mounted on automobiles of various manufacturers transported to a maintenance station, the battery is connected to the terminals after vehicle information required by the simple diagnosis field terminal 30 is input, comprehensive diagnosis using a plurality of diagnostic techniques is performed, and the battery diagnosis result and the purchase price can be confirmed. Hereinafter, a wide range of diagnostic systems corresponding to various batteries will be described in detail.

Fig. 6 is a block diagram showing an example of the configuration of the diagnostic information server 120. The diagnostic information server 120 includes a control unit 121, a communication unit 122, a storage unit 123, a switching unit 124, a registration unit 125, and a diagnostic unit 126, which control the entire server.

The switching unit 124 can selectively switch the diagnosis method for the degradation diagnosis of the battery based on the battery information acquired by the communication unit 122.

The registration unit 125 has a function of registering a newly developed or designed diagnostic algorithm of a simple form. The registration unit 125 can add a new simple diagnostic algorithm or update an old simple algorithm.

The diagnosis unit 126 includes a diagnosis algorithm D1(127), a diagnosis algorithm D2(128), a diagnosis algorithm D3(129), and a charge/discharge algorithm 135. The diagnostic algorithms D1 to D3 are simple diagnostic algorithms and are rapid diagnostic algorithms requiring a relatively short time for diagnosis. The charge and discharge algorithm has high accuracy of the diagnosis result, but the time required for diagnosis is relatively long. The switching unit 124 can select a desired diagnostic algorithm based on the battery information or the diagnostic method selected by the user. The diagnosis section 126 diagnoses the degree of degradation of the battery using the selected diagnosis algorithm. In the example of fig. 6, 3 simple diagnostic algorithms are illustrated for convenience, but the diagnostic unit 126 may have four or more diagnostic algorithms.

Fig. 7 is an explanatory diagram illustrating an example of a diagnostic method for diagnosing the degree of deterioration of the battery. The first diagnostic method in classification is characterized by a long time required for diagnosis but high accuracy of the diagnosis result, and is a method of measuring a capacity using, for example, full charge and discharge. The diagnostic method is based on a discharge current integration method at the time of complete charge and discharge, and after a battery is charged once to a full charge (SOC is 100%), the battery is discharged until the SOC becomes 0%, and the current integration method is used to determine the full charge capacity at the time of discharge, and the full charge capacity is divided by the initial full charge capacity to estimate SOH (State of Health).

The second diagnostic method is a simple diagnostic method in which the diagnostic time is shorter (for example, about 0.1 second to 10 minutes) than the first diagnostic method. The second diagnosis means includes, for example, a charge curve analysis method, a discharge curve analysis method, a table lookup from an internal resistance, a model-based estimation, and the like.

The charge curve analysis method is a method of measuring the voltage, current, and temperature of a battery during charging, recording these data as a charge curve, setting initial values of parameters indicating the internal state of the battery, estimating the parameters by regression calculation, and calculating the state of the battery (for example, the battery capacity).

The discharge curve analysis method comprises the following steps: the discharge curve is characterized by voltage differential or the like, and the change in the capacity of each active material of the positive electrode and negative electrode of the battery is extracted to calculate the state of the battery (for example, the battery capacity).

Looking up the table according to the internal resistance means: the relationship between SOH and internal resistance is obtained in advance, and a table is prepared, and the SOH is obtained by a table look-up from the measured internal resistance.

The model-based estimation means: SOH is estimated by correlating SOH with a specific parameter in a model used in SOC estimation and estimating the parameter on the basis of the correlation. For example, SOH can be obtained by expressing the full charge capacity of the battery as the capacity of a capacitor in an equivalent circuit model and estimating the capacity. In addition, SOH can also be estimated using a neural network. Further, the diagnostic method is not limited to that illustrated in the drawings. The diagnosis method illustrated in fig. 7 may be configured for each car manufacturer, each battery manufacturer, and each battery type, for example. For example, it can be classified into automobile manufacturers M1, M2, M3 and other automobile manufacturers.

The diagnostic method analysis terminal 160 includes hardware such as a CPU (e.g., a multiprocessor in which a plurality of processor cores are mounted), a gpu (graphics Processing units), a dsp (digital Signal processors), and an FPGA (Field-Programmable Gate Arrays). The diagnostic method analysis terminal 160 can generate a new diagnostic algorithm for the diagnostic information server 120 by using data obtained by the first diagnostic method with high diagnostic accuracy as learning data for the simple diagnostic algorithm composed of the neural network, and can perform relearning of the simple diagnostic algorithm.

The diagnostic information server 120 (registration unit 125) can register a second diagnostic method having a diagnostic time shorter than that of the first diagnostic method as needed, and diagnose the degree of degradation of the battery using the registered second diagnostic method. Thus, the degree of deterioration can be estimated in time also for a newly marketed automobile or a new battery mounted on the automobile.

The diagnostic method analysis terminal 160 may provide the data obtained by the first diagnostic method as learning data to the analysis and diagnosis method vendor.

Next, an operation on the simple diagnosis field terminal 30 will be explained. The field terminal 30 can switch between a battery information input mode, a diagnosis result presentation mode, and a battery evaluation result mode, and display the modes.

Fig. 8 is a schematic diagram showing an example of the battery information input mode 301. A battery mounted on a vehicle transported to a maintenance station such as a serviceman is connected to the simple diagnosis field terminal 30, and a user such as the serviceman can input or select various information by selecting the battery information input mode 301. The information input or selected includes, for example, the manufacturer name of the automobile, the type of the automobile, the year of the type of the automobile, the management number of the automobile, the vehicle number (the manufacturer's manufacturing number, etc.), and the use status of the automobile (for example, the travel distance, the number of years of use, the frequency of use, the average travel distance per day, etc.). The input information may be a direct input or may be a selection from a plurality of displayed options. Although not shown, the simple diagnostic field terminal 30 may include the battery ID and measurement data of the battery (for example, current, voltage, temperature, and the like) as input information. The battery ID can be input by, for example, reading a two-dimensional barcode attached to the battery. In addition, the information input in the battery information input mode 301 may be transmitted to the simplified diagnosis field terminal 30 by a communication terminal (for example, a smartphone) carried by the user using wireless communication.

The easy diagnosis field terminal 30 transmits the inputted information to the diagnosis information server 120.

Fig. 9 is a schematic diagram showing an example of the diagnosis result presentation mode 302. The diagnostic information server 120 can acquire battery information about the battery from the battery information server 110 based on the input information, select one or more diagnostic algorithms for diagnosis of the degree of degradation of the battery based on the information, and diagnose the degree of degradation of the battery using the selected diagnostic algorithms. The diagnostic result presentation mode 302 contains a diagnostic result. In the diagnosis result presentation mode 302, for example, the management number of the automobile, the diagnosis method, the recommendation method, and the diagnosis methods a to C can be displayed. Here, the recommendation manner may be: for example, when there is a specific diagnosis method or an optimal diagnosis method for each car manufacturer or a battery manufacturer associated with the car manufacturer, the diagnosis method is recommended as a recommended method. The diagnostic mode may also be recommended based on the model of the battery. By selecting a diagnosis mode and operating the 'diagnosis execution' icon, the diagnosis results 1 to 3 of the selected diagnosis mode can be displayed. As a result of the diagnosis (degree of deterioration), for example, the capacity of the battery is several percent (the capacity of the appliance is not made 100%). Generally, 70% is a guaranteed value for capacity. The degree of deterioration may also be displayed as the remaining life of the battery (which may be reached after many years).

The number of the diagnosis methods and the corresponding diagnosis results may be selected by the user or may be set in advance. As shown in fig. 9, by displaying the diagnosis results based on at least three diagnosis manners, even in the case where there is a deviation in the diagnosis results, the most reliable diagnosis result can be determined. The simple diagnosis field terminal 30 may diagnose the degree of degradation of the battery, and the simple diagnosis field terminal 30 may transmit a diagnosis result of the diagnosis to the distributed accounting system and record the diagnosis result in the diagnosis DB or the predetermined DB.

As described above, the diagnostic method for displaying the degree of deterioration of the battery and the diagnostic result of the degree of deterioration when the diagnostic method is used enable the user of the automobile to easily grasp the degree of deterioration of the battery mounted on the automobile without requesting a regular dealer.

Fig. 10 is a schematic diagram showing an example of the battery evaluation result pattern 303. In the battery evaluation result mode 303, a diagnosis method, a comprehensive result, a purchase price, and detailed conditions can be displayed. In the example of the figure, both the integrated result and the purchase price are displayed, but either one may be displayed. Instead of the integrated results, the individual diagnosis results of the individual diagnosis modes may be displayed. The detailed condition includes, for example, information such as contract terms relating to the sale and purchase of the battery. The contract terms include, for example, descriptions defining the sales and purchase of the seller and buyer, the amount of sales, the term of payment, the period of ownership transfer, the liability of default, and the risk of exposure. When the "execute" icon is operated, processing for establishing a battery purchase contract is performed, and when the "do not execute" icon is operated, the battery purchase contract is not established. Further, only either one of the diagnosis result and the purchase price may be displayed.

Fig. 11 is a schematic diagram showing an example of information for correspondingly recording the diagnosis result and purchase price of the battery. The information shown in fig. 11 may be recorded in the diagnosis DB, for example, but may be recorded in another DB. As shown in fig. 11, information on the type of vehicle, the year of the vehicle, the diagnosis day, the diagnosis method, the diagnosis result (SOH, for example), and the purchase price is recorded in association with the battery ID. The vehicle type and the model year are the vehicle type and the model year of the automobile on which the battery is mounted. The diagnostic method may be either the first diagnostic method (full charge/discharge method) or the second diagnostic method (simple method), and here, a simple method with a high expected use frequency is used. The diagnostic result is, for example, SOH 75%, and the purchase price calculated based on the diagnostic result or the like is 10 ten thousand yen. The purchase price is merely an example for explanation, and is not limited thereto. The information illustrated in fig. 11 is recorded in the distributed ledger system.

Fig. 12 is a schematic diagram showing an example of the purchase price of a battery as a comparative example. The comparative example shown in fig. 12 is an example of a purchase price that is not determined by the first diagnostic method (full charge/discharge method) or the second diagnostic method (simple method) of the present embodiment. That is, the types of vehicles and the model years of the vehicles are various, and the types of batteries mounted on the vehicles are also various depending on the manufacturers of the vehicles. In this way, there are cases where it is desired to diagnose the degree of deterioration of the battery, but an appropriate diagnostic method is not known, or the diagnostic method is not established from the beginning, and therefore, it is considered that the degree of deterioration of the battery often cannot be used as a judgment condition when determining the purchase price of the battery. In such a case, as shown in fig. 12, the purchase price of the battery may be determined according to the travel distance, the use period (the period from the registration of the new vehicle to the present), and the like of the vehicle in which the battery is mounted. Further, since the degree of deterioration of the battery is not clear, the purchase price tends to be set as low as possible in the market. In the example of fig. 12, the purchase price of the battery equivalent to that of fig. 11 is 7 ten thousand yen.

As described above, according to the present embodiment, since a wide range of diagnostic systems capable of diagnosing various batteries in one-stop manner can be provided, the degree of deterioration of the battery (diagnostic result) can be incorporated into the calculation of the purchase price of the battery, and a decrease in the market price of the battery can be suppressed. Thus, the remaining value of the battery is clear, and the rental market in which the battery is reused can be expanded and created.

Fig. 13A and 13B are schematic diagrams showing an example of information on the diagnosis result and purchase price after the purchase of the battery is decided in association with the record. The information shown in fig. 13A and 13B may be recorded in the diagnostic DB, for example, but may be recorded in other DBs. As shown in fig. 13A, information on the purchase price, the diagnosis date, the diagnosis method, the diagnosis result (SOH, for example), and the updated purchase price is recorded in association with the battery ID. The purchase price is the purchase price illustrated in fig. 11. It is contemplated that the diagnosis of the battery is performed after the decision to purchase the battery is made. The diagnosis day is the diagnosis day after purchase is decided. The diagnosis of the battery for which the purchase decision is made is assumed to be more time-consuming than the diagnosis performed by taking the automobile to a maintenance factory, and therefore, the diagnosis method of the battery here employs a full charge/discharge method. The SOH was 85% as a result of the full charge-discharge mode. In the simple embodiment illustrated in fig. 11, SOH is 75%. It was determined that the degree of deterioration of the battery obtained by the more accurate diagnosis method was not more serious than the initial diagnosis result. Since the purchase price can be set high in this way, the updated purchase price can be set to 12 ten thousand yen, for example. The updated purchase price is, for example, a transaction price when a maintenance provider such as a 4S shop or a shared service who purchased a battery resells to a reuse operation manager (which may include a refurbisher or a dismantling provider). The actual transaction price of the battery may be the updated purchase price or the latest market price (time price). The transaction unit may be a unit of a battery pack, a unit of a battery module, or a unit of a single battery.

As shown in fig. 13B, information on the purchase price, the latest transaction status, and the updated purchase price is recorded in association with the battery ID. The purchase price is the purchase price illustrated in fig. 11. It is contemplated that the transaction condition of the battery is updated after the decision to purchase the battery is made. In the example of fig. 13B, battery ID: the recent market price of XXX is 10.5-11.5 ten thousand yen. In this way, since the market price is higher than the initially set purchase price, the purchase price can be set high, and therefore, for example, the updated purchase price can be set to 11 ten thousand yen. The information illustrated in fig. 13A and 13B is recorded in the distributed ledger system.

As described above, it is also conceivable that the battery is diagnosed again after the purchase price of the battery is determined, or the market price fluctuates, and the purchase price is updated in consideration of these factors, whereby the remaining value of the battery can be further clarified.

As described above, since the diagnosis result of the degree of deterioration of the battery and the transaction price can be displayed, the user can easily grasp the market value of the battery owned by the user. Further, as described above, by displaying contract terms related to the transaction of the battery and accepting whether or not the transaction of the battery can be performed, the transaction of the battery can be easily performed, and the circulation of the battery having a sufficient market value can be promoted.

The calculation method of the transaction price (purchase price) of the battery can be obtained by, for example, the following equation. That is, the transaction price C is (a + b + C + d + e) × C0. Here, a represents the degree of deterioration, i.e., a weight coefficient with respect to SOH (health). The larger the SOH, the larger the value of a. b is a weight coefficient relative to the diagnostic mode. For example, when the diagnostic method is a single simple method, when a comprehensive diagnosis is performed based on a plurality of simple methods, and when the full charge/discharge method is adopted, the weighting coefficients are b1, b2, and b3, respectively, and there are b1 < b2 < b 3. It may be that the higher the reliability of the diagnosis method, the larger the value of b (b1, b2, b3) is. c represents a weight coefficient of brand influence with respect to the automobile manufacturer or the battery manufacturer, and may be such that the larger the brand influence, the larger the value of c. d represents a weight coefficient with respect to the use period of the battery, and may be such that the shorter the use period, the larger the value of d. e represents a weighting factor reflecting the transaction condition of the battery, and may be such that the higher the market price, the larger the value of e. The weighting coefficients a to e may be normalized as appropriate. The transaction price may also be calculated using a learned model generated through mechanical learning. The aforementioned weight coefficients are not fixed. For example, by collecting information on the diagnosis result, the weight coefficient can be corrected to calculate a more accurate purchase price, and the learned model can be relearned.

As described above, the diagnostic information server 120 can acquire battery information (battery-related information) related to the battery, diagnose the degree of degradation of the battery using the acquired battery information and a plurality of diagnostic methods for diagnosing the degree of degradation of the battery, and output at least one of the diagnosed degree of degradation and the transaction price of the battery corresponding to the degree of degradation. The diagnostic information server 120 can calculate the transaction price of the battery according to the diagnosed degradation degree by using a calculation method that defines the relationship between the degradation degree of the battery and the transaction price.

The diagnostic information server 120 can perform a predetermined calculation on each of the deterioration degrees diagnosed by the plurality of diagnostic methods to diagnose the deterioration degree (integrated result) of the battery. The predetermined operation may be, for example, an average value or a median value of a plurality of diagnostic results.

Various automobile manufacturers exist in the market, and various batteries are mounted, and a method for accurately estimating the various battery capacities has not been established. In the present embodiment, since the battery information of the battery to be diagnosed is acquired and the degradation degree is estimated by selecting a plurality of diagnostic algorithms applicable to the battery, the user of the automobile can estimate the degradation degree of each battery mounted on the automobile of each manufacturer in use. Thus, the user of the automobile can easily grasp the degree of deterioration of the battery mounted on the automobile without requesting a regular dealer. From the viewpoint of the entire industry, a method for evaluating the battery capacity of an automobile in use can be established on the market.

In the present embodiment, since the purchase price can be displayed, the user of the automobile can determine how much difference is paid to change the battery to a new one if the battery of the automobile is replaced at present, and the serviceman can grasp the transaction price of the battery. Generally, the lower the degree of deterioration of the battery, the higher the market value of the battery, so that the battery can be reused by mobile use, stationary use, or the like when the battery has a market value, and the opportunity to make full use of the battery having a market value can be provided.

Fig. 14 is a block diagram showing an example of the configuration of the diagnosis field terminal 40 in detail. The detailed diagnosis field terminal 40 includes a control unit 41 that controls the entire terminal, a communication unit 42, a storage unit 43, a battery pack diagnosis unit 44, a display panel 45, an operation unit 46, and a cell diagnosis unit 47. The detailed diagnosis field terminal 40 may be constituted by a personal computer, a tablet terminal, a smart phone, or the like.

The control unit 41 may be composed of a cpu (central Processing unit), a rom (read Only memory), a ram (random Access memory), and the like.

The communication unit 42 can acquire battery information of a target battery from the battery information server 110. The communication unit 42 can acquire diagnostic information of the target battery from the diagnostic information server 120.

The storage unit 43 is configured by a semiconductor memory, a hard disk, or the like, and can store information acquired by the communication unit 42. The storage unit 43 can store necessary information such as a result of detailed diagnosis of the processing in the field terminal 40.

The display panel 45 may be formed of a liquid crystal display or an organic el (electro luminescence) display. The operation unit 46 may be constituted by a keyboard, a mouse, or the like, for example. The operation unit 46 may be configured by a touch panel or the like, and may perform an input operation of characters on the display panel 45 and an operation of icons, images, characters, or the like displayed on the display panel 45.

The battery pack diagnosis unit 44 has a function of diagnosing the state of the battery pack to be repaired or regenerated (refurbished or the like). By connecting the battery pack to a desired terminal, the voltage, current, temperature, soc (state of charge), and the like of the battery can be measured. The battery pack diagnosis unit 44 can estimate the degree of deterioration of the battery pack using the first diagnosis method based on the discharge current integration method at the time of complete charge and discharge described above. The battery pack diagnosis unit 44 can also perform diagnosis based on the second diagnosis method.

The cell diagnosis unit 47 can measure the voltage, the current, the temperature, the soc (state of charge), and the like in units of cells after the battery pack as a target is divided into cells. The cell diagnosis unit 47 can estimate the degree of deterioration of the battery pack by using the first diagnosis method based on the discharge current integration method at the time of complete charge and discharge. In addition, if the cell is a cell in which the cell state (for example, time-series data of voltage, current, temperature, and the like) can be recorded in the memory mounted in each cell, the cell diagnosis unit 47 can read data from the memory in the cell and estimate the degree of degradation of the cell. The detailed diagnosis field terminal 40 can provide the data obtained by the single diagnosis unit 47 to the analysis and diagnosis type business as data for learning.

The detailed diagnosis field terminal 40 (control unit 41) can acquire battery information on the battery detached from the vehicle from the battery information server 110 via the communication unit 42, acquire diagnosis information indicating the degree of deterioration of the battery from the diagnosis information server 120, and determine whether repair/regeneration is possible or not based on the acquired battery information and the diagnosis information. For example, if the SOH indicating the degree of deterioration is equal to or less than a predetermined threshold, it is considered that the regeneration cannot be repaired. Here, the threshold value may be set to a value to the extent that the battery cannot be used fixedly, for example.

The detailed diagnosis field terminal 40 can acquire battery information on the battery to be repaired and regenerated or the repaired and regenerated battery after the repair and regeneration from the battery information server 110, diagnose the degree of degradation of the battery using the acquired battery-related information and the first diagnosis method based on the discharge current integration method at the time of full charge and discharge, transmit the diagnosis result to the diagnosis information server 120, and record the diagnosis result in the diagnosis DB.

The detailed diagnosis field terminal 40 can diagnose the deterioration degree of each of the plurality of cells included in the battery to be repaired and regenerated using a required diagnosis method, and transmit the diagnosis result to the diagnosis information server 120 to be recorded in the diagnosis DB.

The renovation/dismantling company can use the detailed diagnosis field terminal 40 to acquire battery information and diagnosis information of the battery to be repaired/regenerated (renovated or the like) from the battery information server 110 and the diagnosis information server 120, respectively. The renovator/disassembler can confirm the preliminary diagnosis of the battery pack using the detailed diagnosis field terminal 40 and perform the detailed diagnosis on a single unit basis. The diagnostic information server 120 records the detailed diagnostic results of the update and release quotient in the diagnostic DB. In addition, when the repair and regeneration of the battery is performed by the renovator and disassembler (for example, when a part of the defective cells in the battery pack is replaced, and the cells judged to be good are collected and replaced into the battery pack), the battery related information about the repaired and regenerated battery after the repair and regeneration can be transmitted to the diagnostic information server 120 and recorded in the diagnostic DB.

Fig. 15 is a schematic diagram showing an example of information recorded after the battery is repaired and regenerated. The information shown in fig. 15 may be recorded in the diagnosis DB, for example, but may be recorded in another DB. As shown in fig. 15, information on the repair and regeneration date, the diagnosis result before repair and regeneration, the diagnosis method of the diagnosis before repair and regeneration, the repair and regeneration contents, the diagnosis result after repair and regeneration, and the diagnosis method of the diagnosis after repair and regeneration is recorded in association with the battery ID. In the example of fig. 15, the diagnostic method before repair and regeneration is the full charge/discharge method, and the SOH is 75% as a result of the diagnosis. The repair/regeneration contents may be a replacement of the battery pack, a replacement of the cell, or the like. Although not shown, the number of cells to be replaced, the cell ID of a cell to be loaded into the battery, the cell ID of a cell to be removed from the battery, the diagnostic result of each cell, and the like may be recorded. The diagnostic mode after repair and regeneration was a full charge-discharge mode, and the SOH was 85% as a result of the diagnosis. By removing a bad cell and replacing it with a good cell, the SOH of the battery increases, and the remaining value of the battery can be improved. In another example of fig. 15, the diagnostic method before repair and regeneration is the full charge/discharge method, and the SOH is 40% as a result of the diagnosis. When the threshold value is 45%, the SOH is equal to or lower than the threshold value, and therefore it is determined that the battery cannot be repaired and regenerated, and the battery is sent to a recycling company, for example.

Fig. 16 is a block diagram showing an example of the configuration of the detailed diagnosis management terminal 50. The detailed diagnosis management terminal 50 includes a control unit 51 that controls the entire terminal, a communication unit 52, a storage unit 53, a display panel 54, an operation unit 55, and an interface unit 56. The detailed diagnosis management terminal 50 may be constituted by a personal computer, a tablet terminal, a smart phone, or the like.

The control unit 51 may be composed of a cpu (central Processing unit), a rom (read Only memory), a ram (random Access memory), and the like.

The communication unit 52 has a function of communicating with the account management node 10. The communication unit 52 can acquire battery information (for example, information on a battery to be discarded) from the battery information server 110. The communication unit 52 can acquire diagnostic information of the battery to be discarded from the diagnostic information server 120.

The storage unit 53 is configured by a semiconductor memory, a hard disk, or the like, and can store information acquired by the communication unit 52. The storage unit 53 can store necessary information such as a processing result in the detailed diagnosis management terminal 50.

The display panel 54 may be formed of a liquid crystal display or an organic el (electro luminescence) display. The operation unit 55 may be constituted by a keyboard, a mouse, or the like, for example. The operation unit 55 may be configured by a touch panel or the like, and may perform an input operation of characters on the display panel 54 and an operation of icons, images, characters, or the like displayed on the display panel 54.

The interface unit 56 includes a plurality of terminals for connecting a battery (for example, a battery pack), a measurement changeover switch for measuring the battery, and the like, and is capable of measuring data such as a current and a voltage of the battery. The interface unit 56 can be connected to a battery to be discarded.

The control unit 51 can measure the battery to be discarded through the interface unit 56, for example, measure the remaining capacity, and when there is a remaining capacity, completely discharge the battery at a predetermined discharge current value. This prevents electric shock from occurring when the battery is disassembled for disposal.

The recycling manufacturer can acquire battery information (for example, information on rare metal components contained in the discarded battery based on component information at the time of battery manufacture) as a disposal target using the detailed diagnosis management terminal 50, and acquire and confirm diagnostic information of the battery. The rare metal component can be obtained from the battery DB, for example. The recycling company can confirm the disposal method of the battery using the detailed diagnosis management terminal 50, and perform smelting or the like in accordance with the components of rare metals contained in the battery. In recycling, the waste batteries can be separated according to the rare metal components, and the waste batteries with similar components can be collected for recycling treatment.

The detailed diagnosis management terminal 50 can transmit the contents of the recycling process corresponding to the rare metal components contained in the discarded batteries to the recycling server 150. The recycle server 150 can record the recycled content in the recycle DB.

Fig. 17 is a schematic diagram showing an example of information recorded after the battery is recycled. The information shown in fig. 17 may be recorded in the recycle DB, for example, but may be recorded in another DB. As shown in fig. 17, information such as the recycling completion date, the recycling manufacturer, the battery type, the rare metal component, and the recycling method is recorded in association with the battery ID. The battery type means, for example, a lithium ion battery, a nickel hydrogen battery, or the like. The rare metal component includes, for example, lithium, nickel, cobalt, manganese, and the like. As the recycling method, a recycling treatment corresponding to the rare metal component may be performed. For example, the recovery and utilization method may be determined according to the component ratio of lithium, nickel, cobalt, manganese, and the like, the maximum component, and the like. In addition, the recycling mode can determine the best mode according to the battery type and record the mode actually adopted. This enables the user to grasp information relating to the recycling of the battery.

The detailed diagnosis management terminal 50 may transmit the contents of the recycling process to a terminal device of a battery maker or an automobile maker. The contents of the recycling process may include, for example, the weight (recycling and amount of waste) of the recycling process with respect to the weight of the material name (for example, steel, aluminum, copper, resin, LiNiO2, etc.) of the battery, the recycling rate, and the like. This makes it possible to clearly grasp the recovery rate, the processing weight, and the like of the battery by each of the automobile manufacturer and the battery manufacturer.

Fig. 18 is a block diagram showing an example of the configuration of the battery management terminal 60. The battery management terminal 60 includes a control section 61 that controls the entire terminal, a communication section 62, a storage section 63, a display panel 64, an operation section 65, and an information providing section 66. The battery management terminal 60 may be constituted by a personal computer, a tablet terminal, a smart phone, or the like.

The control unit 61 may be composed of a cpu (central Processing unit), a rom (read Only memory), a ram (random Access memory), and the like.

The communication unit 62 has a function of communicating with the account management node 10. The communication unit 62 can acquire battery information (for example, information on a battery to be reused) from the battery information server 110. The communication unit 62 can acquire the diagnostic information of the reused battery from the diagnostic information server 120. The communication unit 62 can acquire the operation information of the recycled battery from the operation information server 130.

Here, the battery to be reused may be, for example, a battery to be fixedly used. The diagnostic information of the battery can be acquired by a diagnostic device provided in a device in which the battery is provided (for example, a power supply device of a power supplier, a base station of a communication carrier, and the like), and the diagnostic information is transmitted from the diagnostic device to the diagnostic information server 120 and recorded in the diagnostic DB. The operation information may be acquired by a management device provided in the device provided with the battery, and the operation information is transmitted from the management device to the operation information server 130 and recorded in the operation DB.

The storage unit 63 is configured by a semiconductor memory, a hard disk, or the like, and can store information acquired by the communication unit 62. The storage unit 63 can store necessary information such as processing results in the battery management terminal 60.

The display panel 64 may be formed of a liquid crystal display or an organic el (electro luminescence) display. The operation unit 65 may be constituted by a keyboard, a mouse, or the like, for example. The operation unit 65 may be configured by a touch panel or the like, and may perform an input operation of characters on the display panel 64 and an operation of icons, images, characters, or the like displayed on the display panel 64.

The information providing unit 66 can generate information for providing the operating state of the reusable battery and the diagnostic information (for example, the degree of deterioration) acquired by the communication unit 62 to the insurance company.

The battery management terminal 60 can acquire battery information on a reused battery that has reused the in-vehicle battery from the battery information server 110, transmit the degree of deterioration of the reused battery diagnosed by the diagnosis method corresponding to the acquired battery information to the diagnosis information server 120, and record the degree of deterioration in the diagnosis DB. In this case, the battery diagnosis may use the function of the diagnostic information server 120.

Fig. 19 is a schematic diagram showing an example of information recorded after the battery is reused. The information shown in fig. 19 may be recorded in the operation DB, for example, but may be recorded in another DB. As shown in fig. 19, information such as the recycling company, the recycling location, the recycling period, the diagnosis date during recycling, and the diagnosis result is recorded in association with the battery ID. The recycling merchant may be the name of the merchant, or may be an ID. If the reuse is mobile use, the reuse company is a car owner (user) or a company that is operating a car, and if the reuse is fixed use, the reuse company is a company such as an electric power company, a power supply facility company, or a communication carrier. The reuse site may be, for example, XX factory batteries, OO power plant batteries, OX electric vehicles, and XX (private) in OO city. The reuse period indicates a use period of the battery. When the deterioration degree is diagnosed again during the use period, the diagnosis date is the diagnosis date during reuse. The diagnostic result is, for example, SOH, which is 60% in the illustrated example. Although it cannot be mounted on an automobile requiring a required cruising distance, it can be sufficiently reused if it is used for a fixed purpose, and a high value-added service of a battery can be provided.

The battery management terminal 60 can acquire the operation state of the reusable battery from the operation information server 130, acquire the degradation degree of the reusable battery from the diagnostic information server 120, and provide the acquired operation state and degradation degree to the insurance company.

As described above, after the battery to be reused is provided to the reusable battery user, the reusable operation manager can perform continuous diagnosis of the reusable battery using the battery management terminal 60, and perform quality management of the reusable battery. In addition, the reuse operation manager can provide the operation state of the reuse battery and diagnostic information (e.g., the degree of deterioration) to the insurance company at a desired timing.

The sales management terminal 70 may be constituted by a personal computer, a tablet terminal, a smart phone, or the like. The reusable battery user inputs a transaction price (purchase price) when a battery transaction is performed in order to reuse a vehicle-mounted battery (for example, stationary use or mobile use) using the sales management terminal 70. The sales management terminal 70 transmits the inputted transaction price to the sales information server 140. The sales information server 140 can record transaction information including transaction prices in the transaction DB.

The sales information server 140 can record the actual transaction price of the battery for which the degradation degree is diagnosed in the transaction DB, and determine a calculation method that defines the relationship between the degradation degree of the battery and the transaction price based on the transaction price recorded in the transaction DB. The calculation method can be obtained by the following equation, for example. That is, the trading price C is (α + β + γ) × C0. Here, α represents a degree of deterioration, that is, a weight coefficient with respect to SOH (degree of health), β represents a weight coefficient with respect to brand influence of an automobile manufacturer or a battery manufacturer, γ represents a weight coefficient with respect to a usage period of the battery, and C0 represents a reference transaction price. The higher the SOH and the larger the coefficient α, the greater the brand influence, the larger the coefficient β, the shorter the battery life, and the larger the coefficient γ. By collecting the transaction prices of various batteries from users who purchased the batteries as objects of reuse, it is possible to know the price fluctuation of the batteries in the market. By adjusting the calculation method as needed in accordance with the price change, the calculation method can be determined in consideration of the market trading situation, and the accuracy of the calculation method can be improved.

Next, a platform structure of a wide variety of diagnostic systems using the distributed ledger system will be described.

Fig. 20 is a flowchart showing an example of processing between the field terminal for easy diagnosis 30 and the distributed accounting system. Since the "service provider such as a 4S shop or a shared service" uses the simple diagnosis field terminal 30, the following description will be mainly made of the simple diagnosis field terminal 30. The processing from S1 to S11 will be described below.

S1: the easy diagnosis field terminal 30 is inputted with battery information. Here, the battery pack ID to be maintained is input: 001 of the battery. The battery information that is input may be the information illustrated in fig. 8.

S2: the point of easy diagnosis terminal 30 sends a request for diagnostic information to the distributed ledger system. The easy diagnosis field terminal 30 can transmit the inputted battery information (including the battery ID, the measurement data of the battery) to the distributed accounting system together with the diagnosis information request.

S3: the distributed ledger system sends a diagnosis request to the diagnosis information server 120 through the ledger administration node 10. Here, the diagnostic information server 120 can diagnose the degree of degradation of the battery using the acquired battery information and a plurality of diagnostic methods for diagnosing the degree of degradation of the battery. Further, the simple diagnosis field terminal 30 may perform a battery deterioration degree diagnosis, and the diagnosis result of the simple diagnosis field terminal 30 may be transmitted to the distributed accounting system and recorded in the diagnosis DB or the predetermined DB.

S4: the distributed ledger system acquires a diagnosis result (estimation result of the degree of degradation of the battery) from the diagnosis information server 120 through the ledger administration node 10.

S5: the distributed ledger system records the diagnostic results in distributed ledger 152.

S6: the distributed ledger system calculates a purchase price corresponding to the diagnostic result. Here, the distributed ledger system calculates a purchase price by the diagnostic information server 120 or the sales information server 140, and acquires the purchase price calculated by the diagnostic information server 120 or the sales information server 140.

S7: the distributed ledger system notifies the simple diagnosis field terminal 30 of the diagnosis result and the purchase price. Here, the simplified diagnosis field terminal 30 can display the information illustrated in fig. 10. At this time, the information illustrated in fig. 11 is recorded in the diagnostic DB or the predetermined DB.

S8: at the point of easy diagnosis terminal 30, the operation of purchase decision is carried out.

S9: the point of care terminal 30 sends a record request for transaction information to the distributed ledger system.

S10: the distributed ledger system records transaction information in distributed ledger 152.

S11: the distributed ledger system generates certification information (certification date, formal evaluation flag, etc.) to be recorded in the distributed ledger 152. After that time, the information illustrated in fig. 13A and 13B is recorded in the diagnostic DB or the predetermined DB.

As described above, when the deterioration degree of the battery for vehicle is diagnosed by the pre-registered diagnosis method and the transaction is performed at the transaction price, the certification information (confirmation date, formal evaluation) corresponding to the identification information (for example, battery ID) for identifying the battery can be stored in the distributed account book 152. In this case, the ID of the maintainer such as the 4S shop or the shared service may be stored in the distributed account book 152 in association with the battery ID. The certification information may be in any form as long as it can prove that a regular merchant has performed a regular transaction in a regular diagnosis method in the platform of the diagnosis system. The subscription information includes both subscription information for the merchant and subscription information for the battery.

The processing performed by the ledger administration node 10 can be realized by an intelligent contract. That is, when the degree of deterioration of the battery is diagnosed by a pre-registered diagnostic method and a transaction is conducted under a pre-registered sales condition, the program is automatically executed without intervention, so that a flag for a formal evaluation is set for the battery ID and the merchant ID (identification code for identifying the merchant), for example, the number of battery validations for the battery ID and the number of merchant validations for the merchant ID are increased by 1.

The approval information may include an approval rating (e.g., ratings of 1 to 5). The approval information for the merchant may be determined based on the number of processes (diagnosis, event such as sales) performed by the merchant (approval number), the approval number in a predetermined period, and the like. As the identification information of the battery, for example, it may be decided according to the identification level (e.g., average value) of one or more merchants who handle the battery. In addition, the battery identification level may be higher in a case where the battery is diagnosed in a plurality of diagnostic methods than in a case where the battery is diagnosed in one diagnostic method. In addition, the approval level of the battery diagnosed in the first diagnosis method based on the full charge and discharge may be made higher than the approval level of the battery diagnosed in the second diagnosis method as a simple method. Thereby, the credit of the traded battery can be reflected. In addition, the credit degree of the merchant added with the diagnosis system platform can be reflected. In addition, regarding the approval level of the battery, for example, when the battery is recycled by a regular (approved) 4S store, a provider of a shared service or the like, a refurbishment/decommissioning company, a reuse management manager, or a recycling company, the number of points may be increased in accordance with the processing of each merchant, and when some merchants are not regular, the number of points is not increased. The approval levels given to the respective battery IDs are, for example, totaled as approval levels of car manufacturers or battery manufacturers.

Fig. 21 is a flowchart showing an example of processing between the detailed diagnosis field terminal 40 and the distributed accounting system. Since the "reviewer/disassembler" uses the detailed diagnosis field terminal 40, the detailed diagnosis field terminal 40 will be mainly described below. The processing from S31 to S41 will be described below.

In addition, the detailed diagnosis management terminal 50 may provide the content of the recycling process to the manufacturer of the battery or the manufacturer of the vehicle.

When the battery is recycled, the content of the recycling process performed by the recycling provider may be stored in the distributed ledger system in association with the battery ID of the battery.

Fig. 24 is a flowchart showing an example of processing between the diagnosis management terminal 20 and the distributed ledger system. Since the "manufacturer, sharing service provider" uses the diagnosis management terminal 20, the following description will be mainly made of the diagnosis management terminal 20. The processing from S91 to S99 will be described below.

S91: the diagnosis management terminal 20 transmits a battery information request, a diagnosis information request, an operation state request, and a usage history request of the battery to the distributed ledger system.

S92: the distributed ledger system sends a battery information request to the battery information server 110 through the ledger administration node 10, and acquires battery information from the battery information server 110. The distributed ledger system sends a diagnostic information request to the diagnostic information server 120 via the ledger administration node 10, and acquires diagnostic information from the diagnostic information server 120. The distributed ledger system transmits an operation state request to the operation information server 130 via the ledger administration node 10, and acquires the operation state of the battery from the operation information server 130. The distributed ledger system transmits a usage history request to the recycle server 150 via the ledger administration node 10, and acquires the usage history of the battery from the recycle server 150. Here, the use history of the battery is recorded in the recycle DB, but may be recorded in another DB.

S93: the distributed ledger system notifies the diagnosis management terminal 20 of battery information, diagnosis information, operation state, and usage history of the battery.

S94: the diagnosis management terminal 20 determines the operation performance of the battery.

S95: the diagnosis management terminal 20 calculates the average life and the recovery rate of the battery from the determined operation results.

S96: the diagnosis management terminal 20 determines an optimum operation method of the battery based on the calculated average life, operation performance, diagnosis information, and the like. Here, the optimum operation method may vary depending on the type of the battery, and even the same type of battery may vary depending on the operation schedule of the battery (for example, a 1-day charge/discharge schedule, a load pattern such as a charge/discharge amount, and the like).

S97: the diagnosis management terminal 20 provides the distributed ledger system with the performance data of the battery and the optimal operation method.

S98: the distributed ledger system records the provided information in distributed ledger 152.

S99: the distributed ledger system generates certification information (certification date, formal evaluation flag, etc.) to be recorded in the distributed ledger 152.

The approval information may include an approval rating (e.g., ratings of 1 to 5). For example, the determination level may be determined based on the number of information items provided by the manufacturer or the sharing service provider, the amount of information, the collection efficiency, the number of determinations within a predetermined period, and the like.

According to the present embodiment, since the battery information, the diagnostic information, the operation state, and the use history of the various batteries are shared on a common platform, the optimum operation method can be provided to the customer not only for the battery of the own company but also for the batteries of other companies. In addition, if the number of certifications of the car manufacturer or the battery manufacturer who is a platform for the diagnostic system is large or the number of certifications of the battery manufactured and sold by the car manufacturer or the battery manufacturer is large, the evaluation on the market is high, which can be advantageous.

Next, a display example of information provided by the distributed ledger system will be described.

Fig. 25 is a schematic diagram showing an example of the evaluation information display screen 311 of the merchant. Here, the merchant may be any type of merchant among the manufacturers and the providers of the shared services such as the aforementioned battery and automobile, the maintainers such as the 4S store and the shared services, the refurbishers and the dissembling, the recycling and reusing managers, and the users who reuse the battery, which are incorporated in the diagnostic system platform.

On the evaluation information display screen 311, the merchant can input the merchant type and the merchant name. The input of the type of the merchant and the name of the merchant can be direct input, or can be display list and selection from the list. When the "decision" icon is operated, the inputted evaluation information of the merchant is displayed. The evaluation information includes, for example, a comprehensive evaluation, a business period, a total number of validations, a number of validations in the past year, and the like, but is not limited thereto. The overall evaluation is represented by, for example, 5 stages, and the evaluation value (4.5 points in the illustrated example) can be displayed by the number of stars. When the "detail" icon is operated, the approved content can be displayed as follows.

Fig. 26 is a schematic diagram showing an example of the approval-information display screen 312. The identified date and the identified content of the identified information can be displayed in a list form. The display order may be in order of date, and may be changed as appropriate. The identified content may be specific content of an event (e.g., diagnosis, marketing, repair, recycling, etc.). The filtering condition is a column in which conditions such as the latest 50 pieces and the range of the year, month, and day are set when the number of the approved information is large, and the approved information can be filtered by setting the filtering condition and operating the "execute" icon.

Fig. 27 is a schematic diagram showing an example of the evaluation information search screen 313. In the illustrated example, as the search condition, a condition of a merchant type (manufacturer, provider of shared service, etc., 4S shop, maintainer of shared service, etc., refurbisher, disassembler, recycler, reusable operation manager, reusable battery user), a total evaluation number of the merchant type or more, and a number of the certified number or more may be set. The search condition is not limited to the illustrated example. By setting the search condition and operating the "search" icon, information such as the evaluation information illustrated in fig. 25 can be displayed, for example.

Fig. 28 is a schematic diagram showing an example of the evaluation information ranking screen 314. The evaluation information ranking screen 314 displays the integrated evaluation, the approval number, and the merchant name of the merchant in a list form in the order of the integrated evaluation from the top to the bottom according to the merchant type. Further, by selecting a desired merchant from the displayed merchants (checking a check box) and operating the "detailed" icon, detailed evaluation information of the selected merchant can be confirmed.

This makes it possible to easily confirm which merchant has received a high evaluation for each merchant type. In addition, for the merchant, the evaluation of the merchant is public, so that the merchant is motivated to promote the service of the merchant. Further, since comparison with the peer can be made, it is possible to easily determine whether the situation of the self is better or worse than the peer, and therefore, the self service can be flexibly used as reference information for promoting and improving the self service.

Fig. 29 is a schematic diagram showing an example of the battery search screen 315. On battery search screen 315, as search conditions, the car manufacturer, the vehicle type, the model year, and all or a part of the battery manufacturer may be input. In addition, the current usage form of the battery may be input as the search condition. As the utilization form, any one of mobile utilization, stationary utilization, and recycled utilization may be selected. The mobile utilization means that: after the new battery is mounted on the vehicle, the battery is detached from the vehicle and reused in another vehicle (for example, a vehicle with a short cruising distance). The fixed utilization means that: after the new battery is mounted on the vehicle, the battery is detached from the vehicle and reused in a stationary power storage device or the like. In addition, as the search condition, a price section of the battery may be input. When the battery cell is distributed in the market, the battery can be searched for each price range. When a search condition is input and the "search" icon is operated, the following battery use information can be displayed.

Fig. 30 is a schematic diagram showing an example of the battery use information screen 316. On the battery use information screen 316, the use mode, price, and the like are displayed in association with the battery ID. The example of fig. 30 shows a case where "recycled" is selected as the usage mode of the battery, and the usage modes show all usage modes up to recycling. Further, by selecting a desired battery ID from the displayed battery IDs (checking a check box) and operating a "select" icon, history information relating to the selected battery ID can be displayed as follows.

Fig. 31 is a schematic diagram showing a first example of the battery history information screen 317. On the battery history information screen 317, the battery manufacturer, the battery model number, the battery evaluation, and the battery history information are displayed for each battery ID. The evaluation is represented by five stages, for example, and the evaluation value (4.5 points in the illustrated example) can be displayed by the number of stars. In the history information, year, month, day, business, event, and usage form (mobile usage or fixed usage) are displayed in order of date. For example, the list of the manufacture performed by the battery manufacturer, the diagnosis and sales performed by the maintenance company, the regeneration and sales performed by the refurbishment/dismantling company, the diagnosis performed by the reuse company, the recycling performed by the recycling company, and the like is displayed. Further, the history information is recorded in the history DB by the history information server 170.

The merchant shown in the history information in fig. 31 is a properly registered merchant, and it can be confirmed that the properly registered merchant has performed proper processing (each processing indicated in the event), and it can be confirmed that the merchant has accepted the platform identification in accordance with the battery ID.

As described above, when at least one of the deterioration degree diagnosis, the operation, the transaction, the reuse, the repair/regeneration, and the recycling of the in-vehicle battery from the start of use to the disposal is performed by a pre-registered dealer, the certification information corresponding to the identification information for identifying the battery can be stored in the distributed account book system.

Fig. 32 is a schematic diagram showing a second example of the battery history information screen 318. In the example of FIG. 32, history information of two batteries (battery ID: XXXX and battery ID: OOOOOOOOO) is displayed. The two batteries may be selected by the user as appropriate. Battery ID: XXXX is processed by each business in a predetermined manner, and history information from the time of battery manufacture to the present is recorded in a traceable state. Each merchant and each process is certified. This battery is subjected to a normal process by a normal business company and has a clear history of use so far, and therefore has a high evaluation value of, for example, 4.5. On the other hand, battery ID: the history information of oooooooooooooo is kept only until a certain past time, and since the time is not traceable, the evaluation of the battery is low, for example, 2.5.

By thus making a difference in evaluation level between the battery whose history information is recorded at the present time and the battery whose history information is partially or entirely missing, a person is motivated to find a regular business and perform regular processing, thereby reliably performing tracking. This promotes the circulation of regular batteries, and improves the market value of the batteries.
