Description

Battery secondary use support device, in-vehicle terminal, user terminal, battery secondary use support system, and battery secondary use support method

[0001] The present invention relates to a battery secondary use support device, an in-vehicle terminal, a user terminal, a battery secondary use support system, and a battery secondary use support method.

[0002] In recent years, systems have been developed that allow vehicle users of electric vehicles (EVs), hybrid electric vehicles (HEVs), and other vehicles to sell their installed secondary batteries and provide them to predetermined reuse destinations (secondary users) when they give up their vehicles. In these systems, the secondary user (for use as a stationary power source or a mobile power source, for example) is determined based on the state of the secondary battery at the time when its use as an on-board battery (primary use) ends.

[0003] As described above, by providing on-board secondary batteries that have completed their primary use to designated secondary users, it is possible to meet the needs for storage power sources for each secondary use application while reducing the amount of secondary batteries that are discarded. For this reason, it is desirable to widely disseminate the above-mentioned systems that supply on-board secondary batteries to secondary users.

[0004] One way to popularize this system is to encourage primary users (vehicle owners) to sell their secondary batteries to secondary users. From this perspective, there is known a technology for estimating the degradation state of the secondary battery, which directly affects the battery value when it is offered to secondary users.

[0005] WO2021 / 193006A1 discloses a battery reuse support system that estimates the battery's deterioration state at the planned time of sale obtained from the user based on the battery's deterioration state while the vehicle is in use (during primary use), determines multiple product types (secondary use destinations) that can be installed based on the estimated deterioration state, calculates the trading price (predicted selling price) of the battery for each product type, and notifies the user.

[0006] However, in WO2021 / 193006A1, the battery degradation state at the planned sale date is calculated based on a predetermined uniform degradation line, which means that the estimated battery degradation state obtained may deviate from the actual value, and the reliability of the predicted selling price ultimately notified to the user may not be ensured.

[0007] In particular, it is expected that the period from when a user is notified of the predicted selling price while using a vehicle until the battery is removed from the vehicle and provided to a secondary user may extend to several years to a decade. Therefore, there is a concern that an estimated value of the battery deterioration state calculated based on a uniform deterioration line will deviate significantly from the actual value, significantly reducing the reliability of the predicted selling price notified to users. As a result, there is a risk that the effectiveness of encouraging users to provide secondary batteries to secondary users will be reduced.

[0008] Therefore, an object of the present invention is to more effectively encourage users to provide secondary batteries for secondary use, and to encourage further provision for secondary use, thereby reducing the amount of discarded batteries.

[0009] According to one aspect of the present invention, there is provided a battery secondary use support device that supports a user of a vehicle equipped with a secondary battery in providing the secondary battery for secondary use. The battery secondary use support device includes: a degradation history data generation unit that generates degradation history data indicating the progression of degradation of the secondary battery from a predetermined reference time to the present based on usage trend information of the vehicle or the secondary battery; a battery state data generation unit that calculates a predicted battery state quantity that indicates the state of the secondary battery at a predetermined time when primary use ends or when secondary use starts based on the degradation history data and generates predicted battery state data including the predicted battery state quantity; a user-provided data generation unit that generates user-provided data based on the predicted battery state data; and a data output unit that outputs the user-provided data to a user terminal operated by a user and / or an on-board terminal installed in the vehicle.

[0011] Hereinafter, each embodiment of the present invention will be described with reference to the drawings.

[0012] [First Embodiment] Fig. 1 is a diagram illustrating the configuration of a battery secondary use support system 10 according to this embodiment. Fig. 2 is a block diagram illustrating the details of each component of the battery secondary use support system 10. The battery secondary use support system 10 of this embodiment is configured as a system that generates information encouraging each user U (U1, U2, ... Un) of each vehicle V (V1, V2, ... Vn in Fig. 1) equipped with an on-board secondary battery to provide the secondary battery for secondary use (reuse), and provides the information to each user U. Note that each vehicle V in this embodiment is assumed to be an electric vehicle, a hybrid vehicle, or the like equipped with an on-board secondary battery.

[0013] In particular, the battery secondary use support system 10 mainly comprises a battery secondary use support device 20, a user terminal UT (UT1, UT2, ... UTn) operated by each user U, and an in-vehicle terminal VT (VT1, VT2, ... VTn) installed in each vehicle V.

[0014] The battery secondary use support device 20 is connected to a user terminal T and an in-vehicle terminal VT via a predetermined network 100 so as to be able to communicate with each other. The network 100 is configured with various hardware and communication protocols for enabling communication between the battery secondary use support device 20, each user terminal UT, and each in-vehicle terminal VT. In particular, the communication function between each user terminal UT and the battery secondary use support device 20 is realized by various communication protocols such as TCP / IP for wide area network communication. Furthermore, the communication function between the in-vehicle terminal VT and the battery secondary use support device 20 is realized by various communication protocols for realizing so-called telematics (mobile communication system).

[0015] The following describes in detail each component of the battery secondary use support system 10. Note that in the following, to clarify that the description is made on the basis of any one of the users U (U1, U2, ... Un), the symbol "k" (k = any integer from 1 to n) is used as appropriate. The same applies to each user terminal UT (UT1, UT2, ... UTn), each vehicle V (V1, V2, ... Vn), and each in-vehicle terminal VT (VT1, VT2, ... VTn).

[0016] <Battery secondary use support device 20> The battery secondary use support device 20 is configured as a computer equipped with various arithmetic / control devices, storage devices, and input / output devices, and with programs for executing desired arithmetic / control processing stored in the storage devices. The battery secondary use support device 20 receives a request from a user terminal UTk and acquires usage trend information and vehicle location information for the vehicle Vk or secondary battery used by the user Uk from the in-vehicle terminal VTk. Then, based on this information, the battery secondary use support device 20 generates predicted battery state data for the secondary battery corresponding to the user Uk. Furthermore, the battery secondary use support device 20 generates user-provided data for the secondary battery from the predicted battery state data and outputs it to the user terminal UTk.

[0017] In more detail, the battery secondary use support device 20 has an in-vehicle battery management server 21, a battery status data generation unit 22, a user-provided data generation unit 23, a data output unit 24, a user management DB 25, a secondary use destination DB 26, and a market price DB 27.

[0018] The in-vehicle battery management server 21 is a server for managing each secondary battery installed in the vehicle Vk. In particular, when the in-vehicle battery management server 21 of this embodiment receives a request signal from a user terminal UTk requesting the presentation of user-provided data, it refers to the user management DB 25 to identify the vehicle Vk and the in-vehicle terminal VTk linked to the user ID included in the request signal. Furthermore, the in-vehicle battery management server 21 acquires usage trend information of the vehicle Vk or the secondary battery installed in the vehicle Vk by communicating with the identified in-vehicle terminal VTk.

[0019] Here, the usage trend information of the vehicle Vk includes parameters suggesting usage trends of the vehicle Vk that may affect the progress of deterioration of the secondary battery to date, such as the frequency of driving the vehicle Vk, the distance traveled, and / or the time the vehicle is parked or the time the start switch is off. Furthermore, the usage trend information of the secondary battery includes parameters suggesting usage trends of the secondary battery that may affect the progress of deterioration of the secondary battery to date, such as the number of charge / discharge cycles, the average temperature, and / or the time the secondary battery is maintained in a non-charge / discharge state.

[0020] The in-vehicle battery management server 21 determines whether or not the battery is in a predetermined reference time t ０ (Especially at the time of first use, such as the product shipping date or vehicle purchase date) １ｓ ) to the present, the in-vehicle battery management server 21 generates degradation history data that indicates the transition of the degradation state of the secondary battery. In particular, the degradation history data includes a change history of parameters that suggest the transition of the degradation state (health state) up to the present depending on how the user Uk has used the vehicle Vk. For example, the in-vehicle battery management server 21 calculates a change history of the SOH (State of Health) of the secondary battery as the transition of the degradation state. Here, the SOH is defined as the ratio (capacity maintenance rate) of the current battery capacity (fully charged capacity) to the initial (new) battery capacity (fully charged capacity). Note that a configuration may be adopted in which a change history of parameters (internal resistance, etc.) that suggest the degradation state other than the SOH is calculated. The in-vehicle battery management server 21 then adds the user ID and the desired trading time t included in the request signal to the generated degradation history data. ｂｓ and transmits them to the battery state data generating unit 22.

[0021] The battery state data generating unit 22 ｂｓ Based on the deterioration history data, the predetermined primary use end time t １ｅ Or at the start of secondary use ２ｅ A predicted battery state quantity A representing the state of the secondary battery at ｋ and generate predicted battery state data including the predicted battery state amount. ｋ is at the start of secondary use t ２ｅ In this case, the estimated battery state quantity A is calculated as a state quantity estimate of the secondary battery that may affect the selectable secondary use destination Su or the selling price. ｋ For example, the secondary use start time t ２ｅ The battery state data generating unit 22 also calculates the predicted battery state quantity A ｋ Then, the battery state data generating unit 22 generates predicted battery state data including the user ID and the desired trading time t ｂｓand transmits the data to the user-provided data generating unit 23. Details of the processing in the battery status data generating unit 22 will be described later.

[0022] The user-provided data generating unit 23 determines the secondary usage start time t based on the vehicle position information and predicted battery state data acquired from the in-vehicle terminal VTk. ２ｅ Here, the predicted selling price sp is calculated based on the set secondary use start time t ２ｅ The user-provided data generating unit 23 then generates user-provided data including the calculated predicted selling price sp, associates the user-provided data with a user ID, and transmits the data to the data output unit 24. Details of the processing by the user-provided data generating unit 23 will be described later.

[0023] The data output unit 24 outputs the user-provided data to the user terminal UTk linked to the user ID. The data output unit 24 may have a so-called SaaS (Software as a Service) function that displays the predicted selling price sp and other necessary information included in the user-provided data on the display screen of the user terminal UTk in a desired display format.

[0024] The user management DB 25 is a database that stores a user ID that is uniquely assigned to a user terminal UTk and a vehicle ID that is uniquely assigned to a vehicle Vk and an in-vehicle terminal VTk used by the user Uk in association with each other.

[0025] The secondary-use destination DB 26 is a database that stores information on secondary-use destinations Su (providing locations and secondary-use applications of secondary batteries) according to the battery status. The providing location of a secondary battery refers to the location to which the secondary battery is provided (transported) when secondary use begins. The secondary-use application refers to the specific use of the secondary battery during secondary use (for example, as a stationary power source, a mobile power source, or for use on a mobile object).

[0026] The market price DB 27 is a database that stores battery transaction prices according to the battery state, secondary use destination Su, and time of sale. In particular, the battery transaction prices stored in the market price DB 27 are determined by correcting a basic transaction price determined from the battery state and secondary use purpose based on market fluctuations such as increases or decreases in demand according to the time of sale.

[0027] <User Terminal> The user terminal UTk is a terminal operated by the user Uk, and is configured as a mobile terminal such as a smartphone or a tablet terminal, or a personal computer such as a notebook computer (laptop) or a desktop computer.

[0028] In particular, when the user terminal UTk detects an input operation by the user Uk to request the provision of user-provided data, the user terminal UTk receives a predetermined user ID and a desired trading time t designated by the user Uk. ｂｓ and transmits the request signal including the predicted selling price sp and other necessary information received from the battery secondary use support device 20 to the user, in accordance with a program stored in a memory area held by the user terminal UTk or in a predetermined manner through processing by the battery secondary use support device 20.

[0029] <In-Vehicle Terminal> The in-vehicle terminal VTk is an in-vehicle computer that is mounted on the vehicle Vk and provides necessary information to the battery secondary use support device 20. In particular, the in-vehicle terminal VTk of this embodiment includes a telematics communication device 31 and a vehicle position providing device 32.

[0030] The telematics communication device 31 is a device for realizing communication between the vehicle Vk and other vehicles V, and telematics communication between the vehicle Vk and the battery secondary use support device 20. In particular, in response to a command from the in-vehicle battery management server 21, the telematics communication device 31 outputs detection values ​​from sensors (not shown) mounted on the vehicle Vk and / or a group of data obtained by communication with other vehicles V to the battery secondary use support device 20 as usage trend information of the vehicle Vk.

[0031] The vehicle position providing device 32 is realized by a function (such as a GPS system) for detecting the position of the vehicle Vk, and various hardware and software for transmitting the detected position as vehicle position information to the battery secondary use support device 20. Specific processes executed by the battery secondary use support device 20 will be described in more detail below.

[0032] FIG. 3 is a flowchart illustrating the details of the processing performed by the battery secondary use support device 20.

[0033] In step S100, the in-vehicle battery management server 21 acquires a user ID from the user terminal UTk. ｂｓ Get.

[0034] In step S200, the in-vehicle battery management server 21 acquires usage trend information of the vehicle Vk from the in-vehicle terminal VTk. The user-provided data generator 23 also acquires vehicle position information from the in-vehicle terminal VTk.

[0035] In step S300, the in-vehicle battery management server 21 generates deterioration history data based on the acquired usage trend information. ０ Cycle deterioration history data showing the transition of cycle deterioration of the secondary battery from the reference time t ０ The usage tendency information includes storage degradation history data that indicates the transition of storage degradation of the secondary battery from the start of use to the present. The in-vehicle battery management server 21 generates the cycle degradation history data by referring to the driving frequency (driving time, etc.) of the vehicle Vk included in the usage tendency information. The in-vehicle battery management server 21 also generates the storage degradation history data by referring to the parking frequency (parking time, etc.) of the vehicle Vk included in the usage tendency information.

[0036] In step S400, the battery state data generating unit 22 calculates the desired trading time t ｂｓ and generating predicted battery state data based on the degradation history data.

[0037] FIG. 4A is a flowchart illustrating details of generating predicted battery state data according to this embodiment.

[0038] First, the battery state data generating unit 22 calculates the desired trading time t ｂｓ Based on the deterioration history data, the deterioration profile P ＴＯ１ｋ (t) is calculated (S410). Here, the primary use deterioration profile P ＴＯ１ｋ (t) is the reference time t ０ From now through the end of primary use t １ｅ The function represents the progression of deterioration of the secondary battery according to the usage mode of the vehicle Vk by the user Uk from the time when the primary usage ends t １ｅ means the timing at which the use of the vehicle Vk (secondary battery) by the user Uk ends. In particular, the primary use end time t １ｅ is determined as the time when the secondary battery is removed from the vehicle Vk after the user Uk has completed procedures such as a sales contract for the vehicle Vk (secondary battery). ｂｓ and at the end of primary use t １ｅ However, taking into consideration the period from the completion of procedures such as the sales contract to the time when the secondary battery is actually removed from the vehicle Vk, ｂｓ Add the period to the end of the primary use t １ｅ may be determined.

[0039] More specifically, the battery state data generating unit 22 calculates the reference time t ０ From the end of primary use t １ｅ Cycle deterioration profile P Ｃ１ｋ (t) is calculated. Ｃ１ｋ (t) is the reference time t ０ From the end of primary use t １ｅ In particular, the battery state data generating unit 22 uses the function representing the transition of cycle deterioration of the secondary battery up to the reference time t ０ The cycle deterioration transition from the present to the present is assumed to be maintained from the present onwards, and the cycle deterioration transition is assumed to be maintained at the end of the primary use t １ｅ The function obtained by extending the Ｃ１ｋ(t) is calculated.

[0040] Furthermore, the battery state data generating unit 22 determines the reference time t ０ From the end of primary use t １ｅ A storage deterioration profile P Ｓ１ｋ (t) is calculated. Ｓ１ｋ (t) is the reference time t ０ From the end of primary use t １ｅ In particular, the battery state data generating unit 22 uses the function representing the transition of storage deterioration of the secondary battery up to the reference time t ０ The preservation deterioration transition from the time of the end of primary use t is assumed to be maintained from the present onwards. １ｅ The function obtained by extending the function to the stored degradation profile P Ｓ１ｋ (t) is calculated.

[0041] Furthermore, the battery state data generating unit 22 generates a cycle deterioration profile P Ｃ１ｋ (t) and storage deterioration profile P Ｓ１ｋ (t) to obtain the primary use deterioration profile P ＴＯ１ｋ (t) is calculated. Note that the primary use deterioration profile P ＴＯ１ｋ (t) is the reference time t ０ From the end of primary use t １ｅ This is a function that represents the progression of total deterioration (cycle deterioration + storage deterioration) up to the end of the test.

[0042] Next, the battery state data generating unit 22 generates the storage deterioration profile P Ｓ２ｋ (t) is calculated (S420). Here, the storage deterioration profile P Ｓ２ｋ (t) is the end of the primary use t １ｅ At the start of secondary use from t ２ｅ Storage period [t １ｅ , t ２ｅ ] is a function that represents the transition of storage deterioration of the secondary battery at the start of secondary use t ２ｅ means the date or time when the secondary battery, which has been removed from the vehicle Vk after its primary use, is actually provided to the secondary user Su.１ｅ , t ２ｅ ] means the end of the primary use t １ｅ At the start of secondary use from t ２ｅ This refers to the period during which the secondary battery is stored in a specified location.

[0043] More specifically, the battery state data generating unit 22 calculates the battery state data based on the planned storage period [t １ｅ , t ２ｅ ] and parameters suggesting the environment in the planned storage location (such as storage temperature or humidity), etc., Ｓ２ｋ (t) is calculated.

[0044] Furthermore, the battery state data generating unit 22 generates the primary use deterioration profile P ＴＯ１ｋ (t) and the storage degradation profile P Ｓ２ｋ By integrating (t), the reference time t ０ From the end of primary use t １ｅ After that, secondary use begins ２ｅ A predicted deterioration profile P Ｕｋ (t) is calculated (S430).

[0045] FIG. 4B shows the predicted degradation profile P Ｕｋ As shown in the figure, according to the above calculation, the predetermined reference time t ０ From the present and the time of primary use to the start of secondary use t ２ｅ A predicted deterioration profile P Ｕｋ (t) can be defined.

[0046] FIG. 4C shows the predicted deterioration profile P determined for each of the different users U1, U2, and U3. Ｕ１ , P Ｕ２ , P Ｕ３ As shown in the figure, the above calculation is performed based on various inputs (usage tendency information, etc.) determined for each user U1, U2, U3 (each user ID), and thus a predicted deterioration profile P Ｕ１ , P Ｕ２ , P Ｕ３ can be obtained.

[0047] In the examples shown in FIGS. 4B and 4C, the predicted deterioration profile P Ｕｋ On the other hand, the predicted deterioration profile P Ｕｋ (t) may be calculated as a profile of any parameter (for example, internal resistance) that can indicate a deterioration state other than SOH.

[0048] Returning to FIG. 4A, the battery state data generating unit 22 generates the predicted deterioration profile P Ｕｋ (t) and at the start of secondary use t ２ｅ The state quantity of the secondary battery (predicted battery state quantity A ｋ ) is calculated (S440). ｋ is at the start of secondary use t ２ｅ In particular, the predicted battery state quantity A ｋ is the predicted deterioration profile P as a function of time (season) Ｕｋ (t) At the start of the above secondary use t ２ｅ It can be calculated as the value of

[0049] For example, the predicted deterioration profile P Ｕｋ When (t) is defined as the SOH profile of the secondary battery, the predicted battery state quantity A ｋ is at the start of secondary use t ２ｅ The predicted deterioration profile P Ｕｋ When (t) is defined as the internal resistance profile of the secondary battery, the predicted battery state quantity A ｋ is at the start of secondary use t ２ｅ The internal resistance of the secondary battery at this point (hereinafter also referred to as "predicted internal resistance") is calculated.

[0050] Furthermore, the battery state data generating unit 22 calculates the predicted battery state quantity A ｋ For example, the battery state data generating unit 22 generates predicted battery state data including a user ID, a predicted deterioration profile P Ｕｋ (t), and predicted battery state quantity A ｋA data group formed by combining the above is generated as predicted battery state data.

[0051] Returning to FIG. 3, in step S500, the user-provided data generation unit 23 determines the secondary usage start time t based on the predicted battery state data. ２ｅ The system calculates a predicted selling price sp of the secondary battery at the target location, and generates user-provided data including the predicted selling price sp.

[0052] FIG. 5 is a flowchart illustrating the details of the generation of user-provided data.

[0053] As shown in the figure, the user-provided data generating unit 23 generates predicted battery state data (particularly, predicted battery state quantity A ｋ ) and refer to the secondary usage DB 26 to find the secondary usage candidate Su ［ｍ］ (m is an arbitrary natural number) (S510). For example, the user-provided data generating unit 23 extracts the predicted battery state amount A ｋ is compared with a reference range of the battery state amount determined for each secondary usage destination Su recorded in the secondary usage destination DB 26, and the predicted battery state amount A ｋ One or more secondary usage destinations Su included in the reference range are designated as secondary usage destination candidates Su. ［ｍ］ It is preferable that this reference range be stored in advance in secondary usage DB 26 as part of the information on secondary usage Su.

[0054] Next, the user-provided data generating unit 23 refers to the market price DB 27 and extracts each of the extracted secondary-use destination candidates Su ［ｍ］ At the start of secondary use, ２ｅ Predicted battery state quantity A ｋ The estimated trading price of secondary batteries according to ［ｍ］ (S520). That is, each estimated transaction price vt ［ｍ］ is the predicted battery state quantity A ｋ The secondary use start time t, taking into account the market price according to ２ｅ This will be determined as an estimate of the trading price of secondary batteries in the

[0055] Furthermore, the user-provided data generation unit 23 generates the secondary usage destination candidates Su ［ｍ］For each of these, the secondary battery is transferred from the primary usage location Pu to the secondary usage candidate Su. ［ｍ］ The transportation cost tc required for transportation to ［ｍ］ is calculated (S530).

[0056] More specifically, the user-provided data generation unit 23 first estimates the primary usage location Pu of the secondary battery based on the vehicle position information acquired from the in-vehicle terminal VTk. For example, the user-provided data generation unit 23 generates an area of ​​a predetermined range including the location where the vehicle Vk is mainly located from the vehicle position information, and estimates the location of a facility within the area where the secondary battery can be removed from the vehicle Vk as the primary usage location Pu by referring to a predetermined map database or the like. Furthermore, the user-provided data generation unit 23 calculates the primary usage location Pu and each of the secondary usage destination candidates Su. ［ｍ］ Based on information such as the distance between the location of the secondary use and the location of the secondary use, each candidate Su ［ｍ］ Transportation cost per ［ｍ］ Calculate the following.

[0057] Next, the user-provided data generation unit 23 selects the secondary usage destination candidate Su ［ｍ］ Each estimated transaction price vt ［ｍ］ and the respective transportation costs tc ［ｍ］ More specifically, the user-provided data generating unit 23 calculates the final predicted selling price sp of the secondary battery from each estimated transaction price vt ［ｍ］ From each transportation cost tc ［ｍ］ Each value (vt （１） -tc （１） , vt （２） -tc （２） . . . ) is obtained as the predicted selling price sp of the secondary battery. Then, the user-provided data generating unit 23 generates user-provided data including the obtained predicted selling price sp (S550).

[0058] Returning to FIG. 3, in step S600, the data output unit 24 outputs (transmits) the generated user-provided data to the user terminal UTk or the vehicle-mounted terminal VTk.

[0059] Furthermore, the user terminal UTk or the in-vehicle terminal VTk displays the user-provided data in a predetermined format on a display device (display screen) that the user terminal UTk or the in-vehicle terminal VTk has.

[0060] The effects of the configuration of the battery secondary use support device 20 of this embodiment described above will be described.

[0061] According to this embodiment, a battery secondary use support device 20 is provided that supports a user Uk of a vehicle Vk equipped with a secondary battery to provide the secondary battery for secondary use. This battery secondary use support device 20 detects a predetermined reference time t based on usage trend information of the vehicle Vk or the secondary battery. ０ a degradation history data generation unit (on-board battery management server 21) that generates degradation history data indicating the progress of degradation of the secondary battery from a predetermined secondary use start time t ２ｅ A predicted battery state quantity A representing the state of the secondary battery at ｋ The predicted battery state quantity A ｋ a user-provided data generation unit 23 that generates user-provided data based on the predicted battery state data; and a data output unit 24 that outputs the user-provided data to a user terminal UTk operated by a user Uk.

[0062] This makes it possible to realize logic for predicting the battery state when the secondary battery is provided to the secondary-use destination Su, taking into account the usage mode of the vehicle Vk or secondary battery specific to the user Uk, and providing the user Uk with information obtained from the predicted battery state. Therefore, the reliability of the information to be provided to the user Uk can be ensured, and the user Uk can be further encouraged to provide the secondary battery to the secondary-use destination Su. As a result, the supply of secondary batteries to the secondary-use destination Su can be further stimulated, and the amount of discarded batteries can be reduced.

[0063] In particular, the vehicle battery management server 21 refers to the driving frequency of the vehicle Vk included in the usage trend information and calculates the reference time t ０ Cycle deterioration history data showing the transition of cycle deterioration of the secondary battery from the reference time t０ The battery state data generating unit 22 generates storage deterioration history data that indicates the transition of storage deterioration of the secondary battery from the reference time t ０ From the end of primary use t １ｅ Cycle deterioration profile P Ｃ１ｋ (t) is generated, and the reference time t ０ From the end of primary use t １ｅ A storage deterioration profile P Ｓ１ｋ Furthermore, the battery state data generating unit 22 generates a cycle deterioration profile P Ｃ１ｋ (t) and storage deterioration profile P Ｓ１ｋ Based on (t), at the reference time t ０ From the end of primary use t １ｅ The degradation profile P during primary use represents the total degradation progress of the secondary battery up to ＴＯ１ｋ (t) is generated, and the primary usage deterioration profile P ＴＯ１ｋ (t) to predict the battery state quantity A ｋ Calculate the following.

[0064] This makes it possible to obtain a more reliable predicted battery state quantity A ｋ A specific logic for obtaining the above is realized.

[0065] Furthermore, the battery status data generating unit 22 １ｅ At the start of secondary use from t ２ｅ Storage period [t １ｅ , t ２ｅ ] is a storage deterioration profile P Ｓ２ｋ (t) is calculated, and the primary use deterioration profile P ＴＯ１ｋ (t) and storage degradation profile P Ｓ２ｋ Based on (t), the predicted battery state quantity A ｋ Calculate the following.

[0086] Furthermore, the user-provided data generating unit 23 calculates each predicted selling price sp ［μ］ Maximum selling price sp ［Ｍ］ The candidate for the end of primary use t １ｅ［Ｍ］ Recommended time of sale ｒｅ and stores it in a predetermined storage area (S5400).

[0087] Then, the user-provided data generating unit 23 calculates the recommended selling time t ｒｅ In particular, the user-provided data generating unit 23 of this embodiment generates user-provided data including the recommended selling time t ｒｅ And the maximum selling price sp associated with this ［Ｍ］ and recommended selling time ｒｅ Candidates at the end of each primary use other than t １ｅ［μ］ and the associated predicted selling prices sp ［μ］ and generate user-provided data including the above.

[0088] 7, the data output unit 24 outputs the generated user-provided data to the user terminal UTk. In particular, the data output unit 24 of this embodiment outputs the recommended selling time t ｒｅEach other candidate for the end of primary use t １ｅ［μ］ The process is performed to display the image in a different manner.

[0089] 10 is a diagram showing an example of the display mode of user-provided data on the display screen of the user terminal UTk. In the example of FIG. 10, the transition of the predicted selling price sp for each candidate selling time is displayed on the user terminal UTk. In particular, the transition of the predicted selling price sp increases or decreases depending on the time of selling due to the influence of the market price according to the secondary use destination Su as well as the progress of deterioration of the secondary battery over time. In addition, in this embodiment, the maximum selling price sp ［Ｍ］ (In the figure, sp ［３］ ) Recommended selling time t ｒｅ other candidates for sale (in the figure, sp ［１］ , sp ［２］ , and sp ［４］ ) are clearly shown in distinction from each other. This allows the user Uk to recognize the timing when the secondary battery can be sold at a high price. In the illustrated example, the predicted selling price sp ［μ］ are connected by a straight line, and each predicted selling price sp ［μ］ It is also possible to display only the plot.

[0090] The effects of the configuration of the battery secondary use support device 20 of this embodiment described above will be described.

[0095] This makes it possible to realize specific logic that estimates the timing of sale when the selling price of the secondary battery will be highest from among multiple possible selling times expected for user Uk, taking market fluctuations into consideration, and provides (notifies) user Uk of that timing of sale.

[0096] Third Embodiment A third embodiment will now be described, in which the same elements as those in the first or second embodiment are denoted by the same reference numerals and their description will be omitted.

[0097] In the battery secondary use support device 20 of this embodiment, based on the configuration of the second embodiment, the desired buying and selling time t ｂｓ Then, in S4100 of FIG. 8, the battery status data generating unit 22 acquires the desired trading time t ｂｓ Based on the primary use end time candidate t １ｅ［μ］ In particular, the battery status data generating unit 22 determines the desired trading time t ｂｓand each candidate primary use end time t １ｅ［μ］ Let's say.

In the example shown, the predicted selling price sp ［μ］ are connected by a straight line, and each predicted selling price sp ［μ］ It is also possible to display only the plot.

[0100] The above display allows the user Uk to recognize the timing when he or she can sell the secondary battery at a higher price than the timing at which he or she wishes to sell it.

[0101] The effects of the configuration of the battery secondary use support device 20 of this embodiment described above will be described.

[0102] According to this embodiment, the battery state data generating unit 22 receives the desired trading time t ｂｓ Based on this, the desired trading time t ｂｓ Multiple candidates for the end of primary use, including t １ｅ［μ］ Then, the user-provided data generating unit 23 sets the recommended selling time t ｒｅ And the maximum selling price sp associated with this ［Ｍ］ , and the desired trading time t ｂｓ And the predicted selling price sp linked to this ［ｔｂｓ］ Generate user-provided data including:

[0103] This realizes a specific logic for providing (notifying) the user Uk of a time when he or she can sell the secondary battery at a higher price than the selling time desired by the user Uk.

[0104] Fourth Embodiment A fourth embodiment will now be described, in which the same elements as those in any of the first to third embodiments are given the same reference numerals and their description will be omitted.

[0105] The secondary battery of this embodiment is assumed to be configured as a battery pack consisting of multiple modules. The market price DB 27 stores, as the battery market price, the market price of a pack when the secondary battery is sold in pack units and the market price of a module when the secondary battery is sold in module units.

[0106] The battery secondary use support device 20 of this embodiment performs the following processes based on the processes described in the third embodiment.

[0107] Specifically, in S440 of FIG. 4A, the battery status data generating unit 22 calculates the secondary usage start time t ２ｅ The average SOH (hereinafter also referred to as "predicted average SOH"), lower limit SOH (hereinafter also referred to as "predicted lower limit SOH"), SOH uniformity (hereinafter also referred to as "predicted SOH uniformity"), average internal resistance (hereinafter also referred to as "predicted average internal resistance"), and SOH for each module to be sold (hereinafter also referred to as "predicted individual SOH") are calculated as the predicted battery state quantity A ｋ It is calculated as:

[0108] Then, the user-provided data generating unit 23 first calculates the secondary usage start time t ２ｅ The basic forecast pack transaction price of the secondary battery is calculated based on the specific calculation logic of the basic forecast pack transaction price. ［μ］ However, in this embodiment, the pack market price in the market price DB 27 is referenced when calculating the basic forecast pack transaction price in S520.

[0109] Next, the user-provided data generation unit 23 compares the predicted average internal resistance with a predetermined judgment value. If the predicted average internal resistance is greater than the judgment value, the user-provided data generation unit 23 stores the basic predicted pack transaction price as the predicted pack transaction price in a predetermined storage area. On the other hand, if the predicted average internal resistance is equal to or less than the judgment value, the user-provided data generation unit 23 stores the corrected predicted pack transaction price obtained by upwardly correcting the basic predicted pack transaction price as the predicted pack transaction price in a predetermined storage area.

[0110] Next, the user-provided data generating unit 23 refers to the predicted lower limit SOH and the predicted SOH uniformity from the predicted pack transaction price to calculate the final estimated transaction price vt ［μ］ Calculate the following.

[0111] Specifically, the user-provided data generating unit 23 compares the predicted lower limit SOH and the predicted SOH uniformity with the respective predetermined judgment values. If both the predicted lower limit SOH and the predicted SOH uniformity are equal to or greater than the respective predetermined judgment values, the user-provided data generating unit 23 sets the predicted pack transaction price as the final estimated transaction price vt ［μ］ It is calculated as:

[0112] On the other hand, when at least one of the predicted lower limit SOH and the predicted SOH uniformity is smaller than the judgment value, the user-provided data generating unit 23 reduces the predicted pack transaction price to a corrected predicted module transaction price, and calculates the estimated transaction price vt ［μ］ In particular, the user-provided data generating unit 23 refers to the market price DB 27, extracts the market price of a module having a predicted individual SOH equal to or greater than a certain value, and sets the market price of the module as the predicted module trading price.

[0113] Then, the user-provided data generating unit 23 calculates the estimated transaction price vt ［μ］ and the associated transportation cost tc ［μ］ From this, the predicted selling price of the secondary battery sp ［μ］ Therefore, according to this embodiment, the predicted selling price sp to be provided to the user Uk is calculated by appropriately considering whether the selling method is pack-unit selling or module-unit selling. ［μ］ A specific logic for determining the above is realized.

[0114] FIG. 12 shows a specific predicted selling price sp in this embodiment. ［μ］ In particular, FIG. 12(a) shows a predetermined first sale candidate (for example, a primary use end candidate t １ｅ［３］ ) and the transportation cost tc ［３］ On the other hand, FIG. 12(b) shows the first selling time candidate t １ｅ［３］ A second sale candidate after a predetermined period has elapsed (for example, a primary use end candidate t １ｅ［６］ ) and the transportation cost tc ［６］ This shows:

[0115] The first selling time candidate t shown in FIG.１ｅ［３］ In this case, the predicted lower limit SOH and the predicted SOH uniformity are both equal to or greater than the judgment value, and the estimated transaction price vt ［３］ Furthermore, although the predicted average internal resistance has increased by a certain amount, the predicted average SOH is above the standard, so the estimated transaction price vt is calculated from the pack market price based on the corresponding secondary use destination Su (for example, stationary use rather than EV reuse). ［３］ Then, the transportation cost tc ［３］ is also below the level, the estimated transaction price vt ［３］ Final predicted selling price sp ［３］ will be determined.

[0116] On the other hand, the second selling time candidate t shown in FIG. １ｅ［６］ In this case, the deterioration of the secondary battery has progressed and at least the SOH uniformity has fallen below the judgment value. Therefore, assuming the sale of the module unit, the estimated transaction price vt ［６］ Then, the transportation cost tc ［７］ is also below the level, the estimated transaction price vt ［６］ Final predicted selling price sp ［６］ will be determined.

[0117] Furthermore, according to this embodiment, the recommended selling time t ｒｅ , desired trading time t ｂｓ , and other candidates for sale (primary use end candidates t １ｅ［μ］ ) predicted selling price sp ［μ］ The price can be displayed while reflecting fluctuations across the timing of the changeover between the pack unit selling price and the module unit selling price.

[0118] 13 is a diagram showing an example of a display mode of user-provided data in this embodiment. In the example shown in the figure, as the deterioration of the secondary battery progresses, a predetermined price switching timing (a primary use end candidate t １ｅ［４］ ) is assumed to be equal to or less than the judgment value. １ｅ［４］ In this case, the predicted selling price sp ［μ］The calculation value will change from one based on sales in pack units to one based on sales in module units.

[0119] On the other hand, the above primary use end candidate t １ｅ［４］ From now on, the predicted selling price sp ［μ］ is calculated based on the assumption that the unit of the module is sold. Therefore, it is possible to display the predicted selling price sp that reflects the fluctuations across the timing of the changeover between the unit of the pack selling price and the unit of the module selling price. Therefore, the user Uk can see the progress of deterioration of the secondary battery according to his / her usage mode, fluctuations in the market price including the unit of the pack selling and the unit of the module selling, and the desired selling time t ｂｓ and recommended selling time ｒｅ It is possible to provide (notify) transition information of the predicted selling price sp for a predetermined period including the above.

[0120] In the display example of FIG. 13, the recommended selling time t ｒｅ is the candidate t at the end of primary use １ｅ［４］ The timing to take the highest price (in the figure, the timing of the end of primary use) １ｅ［３］ ) is set as the desired trading time t ｂｓ Candidate t at the end of primary use １ｅ［４］ The timing after that (t １ｅ［６］ ) and the desired trading time t ｂｓ Predicted selling price sp ［６］ is displayed at a relatively low price on the assumption that the module unit is sold. Therefore, according to the display in FIG. 13, the user Uk can see his / her desired trading time t ｂｓ A recommended selling time t when it is possible to sell packs at an earlier time and at a particularly high price at that time. ｒｅ This can prompt the user Uk to sell the secondary battery (provide it to the secondary user Su) as soon as possible. As a result, it is possible to promote the provision of secondary batteries to the secondary user Su when they can be sold in pack units, and it is possible to reduce the amount of waste in module units.

[0121] Furthermore, with the above display mode, even if the time comes when the secondary battery cannot be sold in packs due to individual circumstances of the user Uk, the trend in the predicted selling price sp assuming selling in modules will be displayed. Therefore, even when selling in modules is the only option, the user Uk can be encouraged to sell the secondary battery as soon as possible, thereby reducing the total amount of discarded batteries, including disposal of modules.

[0122] Although the embodiments of the present invention have been described above, the configurations described in the above embodiments merely show some of the application examples of the present invention and are not intended to limit the technical scope of the present invention.

[0123] For example, in each of the above embodiments, the predicted deterioration profile P Ｕｋ (t) is a primary use deterioration profile P ＴＯ１ｋ (t), and the storage period [t １ｅ , t ２ｅ ]. Ｓ２ｋ On the other hand, when the primary use ends, t １ｅ At the start of secondary use from t ２ｅ The storage period [t １ｅ , t ２ｅ ], when the influence of deterioration during the first use is small, the deterioration profile P ＴＯ１ｋ (t) is used as the predicted deterioration profile P Ｕｋ In this case, the secondary use start time t ２ｅ Instead of t, at the end of primary use １ｅ Predicted deterioration profile P Ｕｋ The value of (t) is the predicted battery state quantity A ｋ It can be calculated as:
