The first diagnostic method in the category is characterized in that the time required for diagnosis is long but the accuracy of the diagnostic result is high, and the first diagnostic method is, for example, performing capacity measurement using complete charge / discharge. The diagnostic method is based on the discharge current integration method at the time of full charge / discharge, and once the battery is fully charged (SOC: State of Charge is 100%), it is discharged until the SOC becomes 0%. When discharging, the full charge capacity is obtained by using the current integration method, and the SOH (State of Health) is estimated by dividing by the initial full charge capacity.

Model-based estimation estimates SOH by associating SOH with a specific parameter in the model used in SOC estimation and then estimating that parameter. For example, the SOH can be obtained by expressing the full charge capacity of the battery by the capacity of the capacitor in the equivalent circuit model and estimating the capacity. It is also possible to estimate SOH using a neural network. The diagnostic method is not limited to the one illustrated in the figure.

It is also possible to recommend a diagnostic method according to the model number of the battery. When the user selects a diagnosis method and operates the "execute diagnosis" icon, the diagnosis results 1 to 3 according to the selected diagnosis method are displayed. The diagnosis result (deterioration degree) can display, for example, what percentage of the battery capacity is (assuming that the new capacity is 100%). Generally, 70% is the guaranteed capacity. Further, the degree of deterioration may be indicated by the remaining life of the battery (how many years later the life will be reached).

The number of diagnostic methods and corresponding diagnostic results may be selected by the user or may be a preset number. As shown in FIG. 9, by displaying the diagnostic results based on at least three diagnostic methods, even if the diagnostic results vary, the most probable diagnostic results can be identified. Further, the degree of deterioration of the battery may be diagnosed by the simple diagnosis site terminal 30, and the diagnosis result by the diagnosis performed by the simple diagnosis site terminal 30 may be transmitted to the distributed ledger system and recorded in the diagnosis DB or a predetermined DB. ..

The comparative example shown in FIG. 12 shows an example of the purchase price determined without performing the first diagnostic method (complete charge / discharge method) or the second diagnostic method (simplified method) of the present embodiment. That is, the vehicle type and model year of the automobile are various, and the battery mounted on the automobile may be different depending on the manufacturer of the automobile, and the type of the battery is also various. Then, even if you try to diagnose the degree of deterioration of the battery, there are circumstances such as you do not know the appropriate diagnostic method, or the diagnostic method has not been established in the first place, so when determining the purchase price of the battery, the degree of deterioration of the battery is determined. It is considered that there are many cases where it cannot be used as a judgment material. In such a case, as shown in FIG. 12, the purchase price of the battery is determined by the mileage of the vehicle equipped with the battery, the period of use (the period from new vehicle registration to the present), and the like. In addition, since the degree of deterioration of the battery is unknown, the market tends to set the purchase price as low as possible. In the example of FIG. 12, the purchase price of the battery equivalent to that of FIG. 11 is set to 70,000 yen.

As described above, according to the present embodiment, since it is possible to provide a wide range of diagnostic systems capable of performing one-stop diagnosis of various batteries, the degree of deterioration of the batteries is calculated when calculating the purchase price of the batteries. (Diagnosis result) can be incorporated, and the decrease in the market price of the battery can be suppressed. As a result, the residual value of the battery becomes clear, and the leasing market for reusing the battery can be expanded or created.

FIG. 13 is a schematic diagram showing an example of information recorded in association with the diagnosis result after the purchase decision of the battery and the purchase price. The information shown in FIG. 13 can be recorded in, for example, a diagnostic DB, but may be recorded in another DB. As shown in FIG. 13A, each information of the purchase price, the diagnosis date, the diagnosis method, the diagnosis result (for example, SOH), and the updated purchase price is recorded in association with the battery ID. The purchase price is the purchase price exemplified in FIG. It is also assumed that the battery will be diagnosed after the purchase of the battery is decided. The diagnosis date is the diagnosis date after the purchase decision. Compared to the diagnosis performed by bringing the automobile to the maintenance shop, it is assumed that the diagnosis of the battery for which the purchase decision has been made will be performed with a margin, so here, the battery diagnosis method is a complete charge / discharge method. As a result of the complete charge / discharge method, SOH is assumed to be 85%. In the simplified method illustrated in FIG. 11, the SOH was 75%. It is assumed that the degree of deterioration of the battery by the more accurate diagnosis method is found to be less advanced than the initial diagnosis result. Then, the purchase price can be set higher, so that the renewed purchase price can be set to 120,000 yen, for example. The purchase price after the renewal is, for example, the transaction price when the 4S store that purchased the battery, the maintenance company such as sharing, resells it to the reuse operation manager (may include the refurbishment / dismantling company). Become. The actual transaction price of the battery may be the renewed purchase price or the recent market price (market price). The transaction unit may be a battery pack unit, but may be a battery module unit or a cell unit.

Further, as shown in FIG. 13B, each information of the purchase price, the recent transaction status, and the updated purchase price is recorded in association with the battery ID. The purchase price is the purchase price exemplified in FIG. It is also expected that the battery transaction status will be updated after the battery purchase is decided. In the example of FIG. 13B, it is assumed that the recent market price of the battery ID: XXX is 105,000 to 115,000 yen. Then, since the market price is higher than the initially set purchase price, the purchase price can be set higher, so that the renewed purchase price can be set to 110,000 yen, for example. The information exemplified in FIG. 13 is recorded in the distributed ledger system.

As described above, even after the purchase price of the battery is determined, it is possible that the battery is diagnosed again or the market price may fluctuate, and by updating the purchase price in consideration of these factors, the purchase price may be updated. The residual 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 are displayed, the user can easily grasp the market value of the battery owned by the user. In addition, as described above, by displaying the contract clause regarding the battery transaction and accepting the possibility of the battery transaction, the battery transaction can be easily performed and the market value remains sufficiently. It is possible to promote the distribution of existing batteries.

The calculation method of the transaction price (purchase price) of the battery can be obtained by, for example, the following formula. That is, transaction price C = (a + b + c + d + e) × C0 where a is a weighting coefficient with respect to the degree of deterioration, that is, SOH (soundness). The larger the SOH, the larger the value of a can be. b is a weighting coefficient for the diagnostic method. For example, when the diagnostic method is one simple method, in the case of comprehensive diagnosis by a plurality of simple methods, and the weighting coefficients in the case of the complete charge / discharge method are b1, b2, and b3, b1 <b2 <b3. Can be set. The higher the reliability of the diagnostic method, the larger the value of b (b1, b2, b3) can be. c is a weighting coefficient with respect to the brand power of an automobile manufacturer or a battery manufacturer, and the larger the brand power, the larger the value of c can be. d is a weighting coefficient with respect to the usage period of the battery, and the value of d can be increased as the usage period is shorter. e is a weighting coefficient that reflects the transaction status of the battery, and 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 be calculated using a trained model generated by machine learning. The weighting factors mentioned above are not fixed. For example, by collecting information on the diagnosis result, the weighting coefficient can be modified and the trained model can be retrained in order to calculate a more appropriate purchase price.

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

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

There are various automobile manufacturers in the market, and the batteries installed in them are also diverse, and a method for accurately estimating the capacity of these various batteries has not been established so far. In the present embodiment, the battery information of the battery to be diagnosed is acquired, a plurality of diagnostic algorithms applicable to the battery are selected, and the degree of deterioration is estimated. It is possible to estimate the degree of deterioration of various batteries. As a result, the user of the automobile can easily grasp the degree of deterioration of the battery installed in the automobile without asking an authorized dealer. Also, from an industry-wide perspective, it is possible to establish a method for assessing the capacity of automobile batteries in use on the market.

In the present embodiment, since the purchase price is displayed, the automobile user can determine how much money can be deducted to replace the automobile battery with a new battery if the automobile battery is replaced now, and at the same time, the maintenance business. Can also grasp the transaction price of the battery. Generally, the smaller the degree of deterioration of a battery, the higher the market value of the battery. Therefore, the battery can be reused for running or stationary use at the timing when the market value does not disappear, and the battery with market value is fully utilized. It will be possible to provide an opportunity to do so.
