Description

Technical Field

[0001] The present invention relates to a battery integrated management platform service system and method thereof, and more particularly, to integrally managing the state of health (SOH), reuse grade, and residual value of a battery during the entire usage cycle of the battery, and providing various information services to clients, other servers, or other systems. A platform service system and method thereof are provided.

[0002] This application claims priority based on Korean Patent Application No. 10-2020-0108826 filed on August 27, 2020, and all of the content disclosed in the specification and drawings of the corresponding application is incorporated into this application.

Background Art

[0003] Due to the problem of environmental pollution caused by the use of fossil fuels, environmentally friendly electric vehicles have been in the spotlight. An electric vehicle is equipped with a battery and a motor instead of an engine, and is an automobile that drives a motor with electric power from the battery and travels.

[0004] In an electric vehicle, the performance of the battery is directly related to the driving performance of the electric vehicle. Therefore, when the performance of the battery drops below the critical value, the battery must be replaced. Usually, when the full charge capacity of the battery drops to 80% or less of the initial full charge capacity, it is determined that the battery needs to be replaced.

[0005] On the other hand, the battery used in an electric vehicle contains expensive materials. For example, a lithium secondary battery containing a Ni-Co-Mn-based positive electrode active material contains a large amount of Li, Ni, Co, and Mn. All of these elements are expensive raw materials, and in particular, Co is an expensive raw material that accounts for 20% of the battery manufacturing cost. Therefore, various studies are being actively conducted on the reuse plan of the battery replaced from an electric vehicle, that is, a used battery.

[0006] Used batteries have performance unsuitable for use in electric vehicles, but if their charge capacity is not significantly low, there is no problem with reuse as the batteries of an ESS (Energy Storage System). This is because the batteries used in an ESS do not require the high performance of the battery level used in electric vehicles. That is, as long as the capacity is sufficient, low-output batteries can be used for the ESS.

[0007] On the other hand, batteries unsuitable for use in an ESS cannot be reused any further due to safety issues. Batteries with significantly degraded performance are prone to overcharging or over-discharging states and may cause problems such as thermal runaway. Therefore, it is desirable to classify such batteries as waste batteries and entrust them to a resource recovery company to recycle the raw materials contained in the batteries.

[0008] Electric vehicles can be traded in the used market like many other goods. The price of used items is determined by their residual value, and the residual value is affected by the usage history of the items. That is, even if the usage period is the same, the residual value becomes lower as they age.

[0009] An important factor in determining the residual value of an electric vehicle is the residual value of the battery, which is a core component. However, there is still no model that can reliably evaluate the residual value of the battery based on a unified standard. Therefore, the used price of an electric vehicle is determined by considering the mileage, accident history, and vehicle management status, similar to general vehicles.

[0010] The evaluation of the residual value of the battery of an electric vehicle is also necessary at the time of insurance purchase. This is because the price of automobile insurance is calculated by considering the residual value of the automobile together with the driving history and accident history of the driver. Therefore, the evaluation of the residual value of the battery is an important factor that should also be considered at the time of insurance purchase for used electric vehicles.

[0011] The residual value of a battery can be quantitatively evaluated using a factor called the state of health (SOH). That is, it can be said that the residual value of a battery is proportional to the SOH.

[0012] The SOH is calculated using a parameter that shows a slow change trend depending on the usage cycles of the battery. That is, the SOH can be quantitatively calculated by calculating the ratio of the middle-of-life (MOL) parameter based on the beginning-of-life (BOL) parameter of the battery.

[0013] Parameters commonly considered for calculating the SOH include the full charge capacity and internal resistance of the battery. Recently, electrochemical parameters such as the diffusion coefficient of the electrode and the Coulomb efficiency have also been considered.

[0025] Preferably, the residual value management module may store in the charging DB the identification code of the battery trading system or the insurance company system to which the battery residual value is transmitted, a time stamp indicating the transmission time, and transaction charging information including charging.

[0026] The battery integrated management platform service method according to the present invention for achieving the above technical problems includes: (a) collecting battery characteristic data of an electric vehicle through a network, matching it with a battery identification code, and accumulating and storing it in a battery characteristic data DB; (b) analyzing the battery characteristic data to calculate the state of health (SOH) which is the current health state of the battery, matching it with the battery identification code, and storing it in an SOH history DB; (c) receiving a reuse grade calculation request together with a battery identification code from a client through the network; (d) querying the SOH history DB using the battery identification code to determine the current SOH, referring to predefined reuse grade information for different SOH levels, determining the reuse grade corresponding to the current SOH, and storing it in a reuse grade management DB; (e) transmitting information related to the reuse grade to the client side.

In addition, the platform service system estimates the SOH for the batteries that have entered the reuse stage and continuously manages the reuse grade, enabling integrated management over the entire usage cycle of the batteries. Further, since the SOH of the batteries is managed over the entire usage cycle by the platform service system, the reliability and accuracy of the residual value of the batteries calculated from the SOH can be improved. Also, by utilizing the residual value of the batteries calculated based on accurate SOH information for the trading of used batteries or the calculation of insurance premiums for used electric vehicles, the trading market for used electric vehicles can be activated. In addition, the present invention enables the implementation of a new concept business of battery quality assurance services.

Therefore, it should be understood that the embodiments described in this specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention, so there can be various equivalents and modifications that can replace them at the time of this application.

[0037] FIG. 1 is a block diagram schematically showing the configuration of a battery integrated management platform service system 10 according to an embodiment of the present invention.

[0038] Referring to FIG. 1, the battery integrated management platform service system 10 according to an embodiment of the present invention includes a platform server 20 and a database server 30.

[0039] The platform service system 10 is connected to be able to transmit and receive data to and from the client 50 or other systems 60 through the network 40.

[0040] The client 50 is a program installed on a computer device and is developed to use various services provided by the platform server 20. The functions of the client 50 will be described later.

[0041] The client 50 can be installed on the battery diagnostic device 51 or on the portable terminal 52 of a user who owns the electric vehicle 70. The battery diagnostic device 51 is a computer terminal used by companies that need battery inspections, such as electric vehicle maintenance companies and battery distribution companies. The battery diagnostic device 51 is an on-board diagnostic (OBD) device, and the user's portable terminal 52 can be a smartphone or a tablet PC. However, the present invention is not limited by the type of device on which the client 50 is installed.

[0042] The other system 60 can be an ESS management system 61, a resource recovery management system 62, a battery trading system 63, or an insurance company system 64.

[0043] The network 40 includes a wired and / or wireless communication network that supports Internet services, and any communication network that can provide Internet services in a wired network and / or a mobile environment is included in the scope of the network 40.

[0044] The network 40 may include not only the wired and wireless communication networks provided by a single network operator, but also the wired and wireless communication networks of other network operators through which data is routed when two or more communication entities transmit and receive data. The communication entities may be clients, servers, devices, or systems capable of transmitting and receiving data through the network 40.

[0045] In addition, the battery integrated management platform service system 10 may be connected to be capable of data transmission and reception with the battery management device 71 mounted on the electric vehicle 70 or the charging control device 81 of the charging station 80 through the network 40.

[0046] The network node to which the battery management device 71 and the charging control device 81 are connected may be a wireless network node or a wired network node.

[0047] The wireless network node may be a short-range wireless network node that supports communication protocols such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or a communication base station node of a mobile communication operator. However, the present invention is not limited by the type of network node.

[0048] First, the database server 30 will be described.

[0049] The database server 30 may include battery characteristic data DB31. The battery characteristic data DB31 stores battery characteristic data including a voltage profile and / or a current profile according to the state of charge (SOC) of the battery.

[0050] The voltage profile and the current profile include data sets indicating changes in voltage or current according to the SOC of the battery.

[0051] Desirably, the battery characteristic data can be stored and managed so as to be classified by a battery identification code. The battery identification code may include a battery model code and a battery serial number code.

[0052] In addition, the database server 30 may include a SOH history DB 32. The SOH history DB 32 stores the SOH of the battery determined at a plurality of time points. Desirably, the SOH is stored so as to be classified by a battery identification code, and may be stored together with a time stamp (for example, year / month / day / hour / minute / second) indicating the storage time point of the information so that the change history thereof can be easily grasped.

[0053] In addition, the database server 30 may include a reuse grade management DB 33. The reuse grade management DB 33 stores information related to the reuse grade of the battery. The reuse grade is determined by the SOH section of the battery. The information related to the reuse grade is stored so as to be classified by a battery identification code. The reuse grade information may be stored together with a time stamp so that the change history thereof can be easily grasped.

[0054] In addition, the database server 30 may include a lookup DB 34. The lookup DB 34 may store reuse grade information by SOH. The reuse grade information by SOH is stored so as to be classified by the battery model code. In one example, the reuse grade information by SOH may be a lookup table that maps the corresponding reuse grade using the battery model code and the SOH. In addition, the lookup DB 34 may store residual value information by SOH. The residual value information by SOH is stored so as to be classified by the battery model code. In one example, the residual value information by SOH may be a lookup table that maps the residual value of the corresponding battery using the battery model code and the SOH.

[0055] In addition, the database server 30 may include a reuse tracking management DB 35. The reuse tracking management DB 35 stores reuse tracking information for tracking where used batteries are reused during the entire usage cycle of the battery. Desirably, the reuse tracking information includes the identification code of the battery reuse node, the battery identification code used at the node, and a timestamp indicating the time when use started at the node. The battery reuse node may be, as a battery reuse company, for example, a used battery distribution company, an ESS manufacturer, or a resource recovery company.

[0056] In addition, the database server 30 includes a billing DB 36. The billing DB 36 may store billing information related to an information inquiry when a paid information inquiry is made by an external client 50 or another system 60. The billing information may include the identification code of the external client 50 or another system 60 that requested the information inquiry, a timestamp indicating the time when the transaction for the information inquiry was made, and the fee information levied according to the billing policy.

[0057] The above-described DBs 31 to 36 can be constructed and managed by a commercialized hierarchical database, network database, relational database, a database based on a file system, etc. However, it is obvious to those with ordinary knowledge in the technical field to which the present invention pertains that the present invention is not limited by the commercialized technology utilized in the structure and construction of the DB.

[0058] Next, the configuration of the platform server 20 will be described.

[0059] The platform server 20 is a server computer that executes various control logics necessary in the process of providing a battery integrated management platform service according to an embodiment of the present invention.

[0060] The platform server 20 may include a data management module 21. The data management module 21 collects battery characteristic data including a voltage profile and / or a current profile according to the state of charge (SOC) of the battery from battery management devices 71 mounted on a plurality of electric vehicles 70 through a network 40, and stores the battery characteristic data in a battery characteristic data database DB31 in conjunction with a database server 30.

[0061] Preferably, the battery management device 71 transmits both the battery identification code and the battery characteristic data. Thereby, the data management module 21 can store the battery characteristic data in the battery characteristic data DB31 by matching the battery identification code.

[0062] Optionally, the battery characteristic data may further include a temperature profile according to the SOC of the battery.

[0063] FIG. 2 is a flowchart showing in detail the control logic executed by the data management module 21 according to an embodiment of the present invention.

[0064] Referring to FIG. 2, when the service is started, the data management module 21 determines whether battery characteristic data and a battery identification code are received through the network 40 at step S10. The battery characteristic data and the battery identification code may be transmitted from the battery management device 71 included in the electric vehicle 70 or the charge control device 81 of the charging station 80.

[0065] When it is confirmed that new characteristic data is received, the data management module 21 stores the battery characteristic data together with a time stamp in the battery characteristic data DB31 by matching the battery identification code in conjunction with the database server 30 at step S20.

[0066] Also, the data management module 21 determines whether the time period ΔT has elapsed at stage S30. When it is determined that ΔT has elapsed, the data management module 21 advances the process to stage S10 and returns to the stage of further checking whether there is new reception of the battery identification code and battery characteristic data. Therefore, stages S10 to S20 are repeated each time the time period ΔT elapses. As a result, the battery characteristic data DB31 collects the characteristic data of the batteries mounted on a plurality of electric vehicles 70 and accumulatively records them together with the time stamps.

[0067] Also, the platform server 20 includes an SOH management module 22. The SOH management module 22 analyzes the battery characteristic data stored in the battery characteristic data DB31 to calculate the current SOH of the battery, and can be stored in the SOH history DB32 together with the time stamp by matching with the battery identification code in conjunction with the database server 30. The SOH management module 22 can independently calculate the SOH for each battery and store it in the SOH history DB32. Desirably, the battery characteristic data used when calculating the current SOH is the most recently collected data based on the current time point.

[0068] FIG. 3 is a flowchart showing in detail the control logic executed by the SOH management module 22 according to an embodiment of the present invention.

[0069] Referring to FIG. 3, when the service is started, the SOH management module 22 determines whether new battery characteristic data is stored by querying the battery characteristic data DB31 in conjunction with the database server 30 at stage S40.

[0070] When it is determined that new battery characteristic data has been saved, the SOH management module 22 determines whether the amount of battery characteristic data is sufficient at step S50. This is because a minimum amount of data is required to accurately calculate the SOH. In one example, the SOH management module 22 determines whether the SOC range in which the current profile and / or voltage profile is measured is equal to or greater than a preset width, for example, 60% or more. The width of the SOC range can be increased or decreased in consideration of the reliability of the SOH estimation result and the calculation load.

[0071] When it is determined that a sufficient amount of new battery characteristic data has been saved, the SOH management module 22 analyzes the new battery characteristic data at step S70 to determine the SOH, matches it with the battery identification code, and saves it in the SOH history DB 32 together with the time stamp. On the other hand, if the amount of battery characteristic data is not sufficient, the SOH management module 22 determines whether the time period ΔT has elapsed at step S60. When the ΔT has elapsed, the SOH management module 22 advances the process to step S40 and repeats the above-described steps. As a result, each time the ΔT elapses, the SOH management module 22 can repeat the process of determining the SOH when the amount of new battery characteristic data is sufficient, matching it with the battery identification code, and saving it in the SOH history DB 32 together with the time stamp.

[0072] In the present invention, the SOH can be determined using known techniques.

[0073] In one example, the SOH management module 22 may determine a partial charge capacity by integrating current in a preset SOC interval using the current profile included in the battery characteristic data, and determine the SOH by comparing it with the initial partial charge capacity calculated in the same SOC interval. As the battery degrades, the partial charge capacity calculated in the same state of charge interval decreases, so the ratio of the current partial charge capacity to the initial partial charge capacity may be determined as the SOH. The initial partial charge capacity of each battery model may be predefined and recorded in the lookup DB 34. The SOH management module 22 may use the battery model code included in the battery identification code to look up the initial partial charge capacity of the battery model from the lookup DB 34 and use it to determine the SOH.

[0074] In another example, the SOH management module 22 may calculate an I-V profile by a linear regression method using the current profile and voltage profile included in the battery characteristic data, determine the slope of the I-V profile as the current resistance value of the battery, and determine the SOH by comparing the current resistance value with the initial resistance value. As the battery degrades, the resistance value of the battery increases, so the ratio of the initial resistance value to the current resistance value may be determined as the SOH of the battery.

[0075] In yet another example, the SOH management module 22 may determine the SOH using an adaptive filter that receives the current profile and voltage profile included in the battery characteristic data and outputs the SOH.

[0076] Preferably, the adaptive filter may be a Kalman filter or an extended Kalman filter. The adaptive filter may be derived from a battery model. The battery model may be an equivalent circuit model or an electrochemical model.

[0077] The SOH determination method using an extended Kalman filter is disclosed in Korean Patent Publication No. 2007-0074621 and may be incorporated herein as part of the present invention.

[0078] The disclosed method is a method for determining SOH from the voltage, current, and temperature of a battery using an extended Kalman filter. In an embodiment where the method is applied to the present invention, the battery characteristic data may further include a temperature profile measured by the SOC of the battery.

[0079] In addition, the platform server 20 may further include a reuse grade management module 23.

[0080] The reuse grade management module 23 may receive a reuse grade calculation request together with a battery identification code from the client 50 through the network 40.

[0081] In addition, the reuse grade management module 23 may query the SOH history DB 32 through the database server 30 using the battery identification code to determine the current SOH of the battery. The current SOH is determined with reference to the timestamp information. That is, the most recently saved SOH becomes the current SOH of the battery.

[0082] In addition, the reuse grade management module 23 may determine the reuse grade corresponding to the current SOH with reference to the predefined reuse grade information for each SOH.

[0083] In addition, the reuse grade management module 23 may match the reuse grade corresponding to the current SOH in conjunction with the database server 30 with the battery identification code and save it in the reuse grade management DB 33 together with the timestamp.

[0084] In addition, the reuse grade management module 23 may transmit the determined reuse grade to the client 50 side through the network 40.

[0085] FIG. 4 is a flowchart showing in detail the control logic executed by the reuse grade management module 23 according to an embodiment of the present invention.

[0086] Referring to FIG. 4, the reuse grade management module 23 determines whether a calculation request related to the battery reuse grade is received from the client 50 side through the network 40 at step S80. The calculation request is received together with the battery identification code.

[0087] When it is determined that a calculation request related to the battery reuse grade is received, the reuse grade management module 23 can determine the current SOH of the battery by querying the SOH history DB 32 through the database server 30 using the battery identification code at step S100.

[0088] When it is determined that a calculation request related to the battery reuse grade is not received, the reuse grade management module 23 suspends the process progress until the time period ΔT elapses at step S90, and when ΔT elapses, the process is returned to step S80.

[0089] After step S100, proceed to step S110.

[0090] The reuse grade management module 23 can determine the reuse grade corresponding to the current SOH using the battery model code included in the battery identification code at step S110. That is, the reuse grade management module 23 can determine the reuse grade corresponding to the current SOH of the battery by querying the reuse grade information for each SOH corresponding to the battery model code from the lookup DB 34 through the database server 30. Desirably, the reuse grade information for each SOH can be a lookup table that maps the reuse grade according to the SOH.

[0091] In one embodiment, a battery with an SOH of 80% or more is determined to be of the used car reuse grade, a battery with an SOH of 60% or more and less than 80% is determined to be of the ESS reuse grade, and a battery with an SOH of less than 60% can be determined to be of the resource recovery grade.

[0092] Here, the used car reuse grade means the grade that can be used as a replacement in a used electric vehicle. The battery with the used car reuse grade can be reused in an electric vehicle with low output. For example, the battery with the used car reuse grade can be used in a small electric car, an electric golf cart, an electric two-wheeler, an electric bicycle, etc. The ESS reuse grade means the grade that cannot be used in an electric vehicle that requires high output but can be used in an ESS. An ESS can be a power storage device that stores electrical energy during late-night hours at home, in a building, a factory, etc. In another example, an ESS can be a power storage device that stores renewable energy produced by solar power generation, wind power generation, geothermal power generation, etc. In yet another example, an ESS can be a power storage device used for stabilizing the power grid (grid). In yet another example, an ESS can be an uninterruptible power supply (UPS) that supplies power when a power outage occurs. In yet another example, an ESS can be a power storage device used for a power bank. The resource recovery grade means the grade for recovering the raw material substances used in the battery by discarding it because the SOH is significantly low and reuse is impossible.

[0093] It is obvious to those with ordinary knowledge in the technical field to which the present invention belongs that the SOH range for classifying the reuse grade can be changed according to the battery model. That is, the reuse grade information by SOH can be independently generated for each battery model and stored in the lookup DB34.

[0094] After step S110, proceed to step S120.

[0095] The reuse grade management module 23 can match the reuse grade of the battery with the battery identification code in conjunction with the database server 30 at step S120 and store it in the reuse grade management DB33 together with the timestamp.

[0096] Also, the reuse grade management module 23 can transmit the information related to the reuse grade of the battery to the client 50 side at step S130.

[0097] When the client 50 of the battery diagnostic device 51 receives information regarding the reuse grade of the battery, the client 50 may display the reuse grade of the battery on the display. Then, the battery diagnostic operator (worker) may inform the user of the electric vehicle 70 of the reuse grade of the battery. When the battery has received a used vehicle reuse grade determination, the user may continue to use the battery as it is, or after replacing it with a new one, the existing battery may be sold for use in used vehicles. Also, when the battery has received an ESS reuse grade determination, the user may replace the battery with a new one, and the existing battery may be sold as an ESS reuse battery. Also, when the battery has received a resource recovery grade determination, the user may replace the battery with a new one, and the existing battery may be returned to the battery manufacturer or a battery resource recovery company as a battery for resource recovery.

[0098] When the client 50 installed on the user's mobile terminal 52 receives information regarding the reuse grade of the battery, the user may check the reuse grade of the battery installed in the electric vehicle 70. When the battery has received a used vehicle reuse grade determination, the user may continue to use the battery as it is, or after replacing it with a new one at an electric vehicle repair shop, the existing battery may be sold for use in used vehicles through the electric vehicle repair shop. Also, when the battery has received an ESS reuse grade determination, the user may replace the battery with a new one at the electric vehicle repair shop, and the existing battery may be sold as an ESS reuse battery through the electric vehicle repair shop. Also, when the battery has received a resource recovery grade determination, the user may replace the battery with a new one at the electric vehicle repair shop, and the existing battery may be returned to the battery manufacturer or a battery resource recovery company as a battery for resource recovery through the electric vehicle repair shop.

[0099] On the one hand, a battery determined to be at the used car reuse level or the ESS reuse level can be transmitted from an electric vehicle maintenance facility to the company side for battery reassembly by an off-line transportation means. In one example, the company for battery reassembly can be a battery manufacturing manufacturer. In other examples, the company for battery reassembly can be other companies different from the battery manufacturing manufacturer.

[0100] The company for battery reassembly can disassemble the battery to extract a plurality of cells and then reassemble them as a battery optimized for the reuse level. Here, the cells can be cylindrical cells, pouch cells, or prismatic cells. For example, the company for battery reassembly can disassemble the battery installed in an electric vehicle and reassemble it as a battery that can be used for an ESS.

[0101] During the battery reassembly process, the electrical connection between unit cells can be re-established, sensors, control units, etc. can be attached, and the assembly of unit cells can be housed in an external case.

[0102] On the outer case of the reassembled battery, a one-dimensional barcode, a two-dimensional barcode, etc. containing a battery identification code can be printed. Also, the battery identification code can be recorded in the memory within the control unit included in the reassembled battery.

[0103] In one example, the barcode can further include information related to the battery reuse level. Also, the information related to the battery reuse level can be additionally recorded in the memory within the control unit included in the reassembled battery.

[0104] On the one hand, when the battery extracted from an electric vehicle is reassembled into two or more batteries, the barcode printed on the outer case of the battery may further include a reassembly serial number. Also, the reassembly serial number may be further stored in the memory of the control unit together with the battery identification code. In this way, by the battery identification code being printed on the surface of the outer case of the reassembled battery or recorded in the memory within the control unit, the reuse history of the battery can be traced.

[0105] The reassembled battery can be stocked in a used battery trading company, an ESS manufacturer, or a resource recovery company through the distribution channel. The type of company to which the reassembled battery is transmitted is determined based on the reuse grade of the battery. For the battery stocked in a used battery trading company, an ESS manufacturer, or a resource recovery company for reuse or resource recovery, before entering the reuse or resource recovery cycle, the battery identification code of the battery to be reused or the battery identification code of the battery to be resource recovered is transmitted to the platform service system 10 through the network 40, and the process of tracing the reuse of the battery can be further carried out.

[0106] The platform server 20 may further include a reuse tracking management module 24 for tracking the reuse process of the battery as described above.

[0107] The reuse tracking management module 24 may receive an approval message for approving the reuse of the battery from the client 50 through the network 40.

[0108] In one example, the reuse approval is to approve the reuse of the battery of the electric vehicle 70 in the battery of another used electric vehicle. In another example, the reuse approval may be to approve the reuse of the battery of the electric vehicle 70 as an ESS battery. In yet another example, the reuse approval may be to approve the return of the battery of the electric vehicle 70 for resource recovery and recycling.

[0109] The approval process for battery reuse can be carried out through an approval interface displayed on the screen of the client 50. The approval interface can be provided in the form of a GUI (Graphic User Interface) after information related to the reuse grade of the battery is displayed through the display of the battery diagnostic device 51 or the user's portable terminal 52.

[0110] The reuse tracking management module 24 can, through the approval interface, ask whether to recycle the battery installed in the electric vehicle for use in used vehicles, ESSs, or resource recovery, and provide a GUI for the user to agree thereto.

[0111] When the user operates a GUI, for example, a consent button, the reuse tracking management module 24 can receive a reuse approval message from the client 50 through the network 40.

[0112] In addition, the reuse tracking management module 24 can transmit, through the network 40, the battery identification code of the battery for which reuse approval has been given and battery reuse information including the reuse grade to the reuse company management system. The reuse company management system can be the ESS management system 61 or the resource recovery management system 62. The ESS management system 61 or the resource recovery management system 62 is an integrated management system operated by an ESS manufacturer or a resource recovery company.

[0113] In addition, when the reuse tracking management module 24 receives a battery receipt authentication message including the battery identification code of the battery to be reused from the reuse company management system, it can match the battery identification code included in the battery receipt authentication message with the identification code of the reuse company and save it in the reuse tracking management DB 35 together with a time stamp.

[0114] FIG. 5 is a flowchart showing in detail the control logic executed by the reuse tracking management module 24 according to an embodiment of the present invention.

[0115] Then, the reuse tracking management module 24 determines whether a reuse approval message has been received from the client 50 through the network 40 at step S140. Desirably, the reuse approval message may include a battery identification code for which reuse approval is sought. The reuse approval message may be transmitted from the battery diagnostic device 51 or the user's mobile terminal 52.

[0116] When the reception of the reuse approval message is confirmed, the reuse tracking management module 24 transmits battery reuse information including the battery identification code and the reuse grade of the battery for which reuse approval has been given to the reuse company management system at step S150.

[0117] In one example, when the reuse grade of the battery for which reuse has been approved is the ESS reuse grade, the reuse tracking management module 24 may transmit the battery reuse information to the ESS management system 61 through the network 40. In another example, when the reuse grade of the battery for which reuse has been approved is the resource recovery grade, the reuse tracking management module 24 may transmit the battery reuse information to the resource recovery management system 62 through the network 40. The ESS management system 61 or the resource recovery management system 62 may record and manage the battery reuse information received through the network 40 in a database. The battery reuse information stored in the database is referred to when generating the battery storage authentication message, which will be described later.

[0118] On the other hand, when the reception of the reuse approval message is not confirmed at step S140, the reuse tracking management module 24 pauses the process until the time period ΔT has elapsed at step S160, and when ΔT has elapsed, returns the process to step S140.

[0119] After step S150, proceed to step S170.

[0120] The reuse tracking management module 24 determines at step S170 whether a battery receipt authentication message has been received from the reuse company management system through the network 40.

[0121] The battery receipt authentication message is generated when information related to the battery identification code and the reuse grade is registered in the reuse company management system after the battery that has received the reuse grade is stored in the designated reuse company through the offline distribution channel, and can be transmitted to the reuse tracking management module 24 through the network 40.

[0122] Preferably, the battery receipt authentication message can be transmitted to the reuse tracking management module 24 side through the network 40 after being generated through the following process.

[0123] A one-dimensional or two-dimensional barcode including information related to the battery identification code and the reuse grade may be attached to the battery for which reuse approval has been performed. The reused battery with the barcode attached is stored in the reuse company designated by the operating company of the platform service system 10 through the offline distribution channel. Then, when the barcode attached to the surface of the stored reused battery is scanned by the barcode scanner, the identification code and the reuse grade of the reused battery are input into the reuse company management system. The reuse company management system may be the ESS management system 61 or the resource recovery management system 62. Then, when the battery identification code and the reuse grade of the reused battery input by the barcode scanner match the battery reuse information (the battery identification code and the reuse grade of the reused battery) pre-stored in the database, the reuse company management system may generate a battery receipt authentication message including the battery identification code of the reused battery and the identification code of the reuse company, and transmit it to the reuse tracking management module 24 through the network 40.

[0124] In another example, when information regarding the battery identification code and reuse grade of a reused battery is recorded in the memory of the control unit included in the reused battery, after the reuse company management system reads out the information regarding the battery identification code and reuse grade of the reused battery stored in the memory of the control unit through the communication port of the control unit, if the read information matches the battery reuse information (battery identification code and reuse grade of the reused battery) pre-stored in the database, the reuse company management system may generate a battery storage authentication message including the battery identification code of the reused battery and the identification code of the reuse company, and transmit the message to the reuse tracking management module 24 through the network 40.

[0125] After step S170, proceed to step S180.

[0126] The reuse tracking management module 24 cooperates with the database server 30 to match the battery identification code of the reused battery and the identification code of the reuse company included in the battery storage authentication message, and stores them together with the time stamp in the reuse tracking management DB 35. The time stamp may be regarded as information indicating the point in time when the use of the reused battery was started. Thereby, it is possible to integrally manage whether the reused battery has actually entered the reuse cycle and the current status of the battery reuse.

[0127] According to another aspect of the present invention, the platform service system 10 may provide a reuse grade change notification service that senses that the reuse grade of the battery has been changed and notifies the client 50 side of the user's mobile terminal 52 that the reuse grade has been changed.

[0128] FIG. 6 is a flowchart showing in detail the process in which the reuse grade management module 23 according to an embodiment of the present invention provides a reuse grade change notification service.

[0129] Referring to FIG. 6, the reuse level management module 23 determines whether there is a battery with newly saved SOH by querying the SOH history DB 32 through the database server 30 at stage S190.

[0130] When the reuse level management module 23 confirms that there is a battery with newly saved SOH, it queries the latest SOH and battery identification code of the battery from the SOH history DB 32 in conjunction with the database server 30, refers to the predefined reuse level information by SOH using the battery model code included in the battery identification code, and determines the reuse level of the battery corresponding to the latest SOH.

[0131] If the reuse level management module 23 does not confirm a battery with newly saved SOH at stage S190, it pauses the progress of the process during the time period ΔT at stage S200, and then resumes the process to stage S190.

[0132] After stage S190, it proceeds to stage S210.

[0133] The reuse level management module 23 queries the previously saved reuse level from the reuse level management DB 33 through the database server 30 using the battery identification code of the battery whose reuse level has been determined at stage S210, and determines whether the reuse level has been changed.

[0134] When the reuse level management module 23 determines that there is a change in the reuse level, it generates a message notifying that the reuse level has been changed at stage S230 and transmits it to the client 50 side of the user's mobile terminal 52 through the network 40.

[0135] Then, the user can recognize that the reuse level of the battery installed in the electric vehicle 70 has been changed, visit the electric vehicle maintenance station to replace the battery, and then change the use of the battery extracted from the electric vehicle to a used car battery, an ESS battery, or a battery for resource recovery.

[0136] The reuse level change notification service can be provided through the integrated information display device of the electric vehicle. In this case, the computing device of the electric vehicle can receive, through the wireless communication network, a message notifying that the reuse level of the battery mounted on the electric vehicle has been changed from the reuse level management module 23, and can display it through the screen of the integrated information display device.

[0137] According to still another aspect of the present invention, the platform service system 10 can provide a service capable of continuously managing the reuse level for the battery even when the battery of the electric vehicle is reused as an ESS battery.

[0138] Specifically, the data management module 21 can receive, through the network 40, battery characteristic data including a voltage profile and / or a current profile according to the SOC of the reused battery and the battery identification code of the reused battery from the ESS management system 61 periodically.

[0139] In addition, the data management module 21 can match the battery characteristic data with the battery identification code of the reused battery in conjunction with the database server 30 and store it in the battery characteristic data DB 31 together with a time stamp.

[0140] In addition, the SOH management module 22 can analyze the characteristic data of the reused battery stored in the battery characteristic data DB 31 to calculate the current SOH of the reused battery, and match the current SOH with the battery identification code of the reused battery in conjunction with the database server 30 and store it in the SOH history DB 32 together with a time stamp.

[0141] The reuse level management module 23 can receive a reuse level calculation request together with the battery identification code of the reused battery from the ESS management system 61 through the network 40. Further, the reuse level management module 23 queries the SOH history DB 32 using the battery identification code of the reused battery to determine the current SOH of the reused battery, refers to the battery model code included in the battery identification code and the predefined reuse level information for each OH to determine the reuse level corresponding to the current SOH, saves it in the reuse level management DB 33, and can transmit information related to the reuse level to the ESS management system 61. Then, the ESS management system 61 can match the information related to the reuse level of the battery with the battery identification code and save and manage it in the database.

[0142] According to still another aspect of the present invention, the platform service system 10 can provide a service that automatically provides a notification when the reuse level of a reused battery is changed even when the battery of an electric vehicle is reused as an ESS battery.

[0143] That is, the SOH management module 22 calculates the SOH of the battery based on the characteristic data of the new reused battery stored in the battery characteristic data DB 31 and can accumulate and store it in the SOH history DB 32.

[0144] Further, the reuse level management module 23 determines the reuse level of the reused battery corresponding to the latest SOH, and when the reuse level is changed compared to the previous reuse level, that is, when the reuse level is changed to a resource recovery level, it can transmit the reuse level change information to the ESS management system 61 through the network 40. Desirably, the reuse level change information may include the battery identification code of the battery whose reuse level has been changed.

[0145] When the ESS management system 61 receives the reuse level change information through the network 40, it can save the battery identification code of the reused battery whose reuse level has been changed in the database and output it through the display.

[0146] The ESS manufacturer can transmit batteries with the reuse level changed in the resource recovery level to the resource recovery company, and the resource recovery company can recover the raw material substances (such as Li, Co, Mn, Ni, etc.) contained in the battery through the recycling process of the battery.

[0147] According to still another aspect of the present invention, the platform service system 10 may further include a residual value management module 25.

[0148] The residual value management module 25 receives a battery residual value evaluation request together with a battery identification code from the battery trading system 63 or the insurance company system 64 through the network 40, queries the SOH history DB 32 using the battery identification code to determine the current SOH of the battery, and determines the residual value of the battery corresponding to the current SOH by referring to the battery model code included in the battery identification code and the pre-defined residual value information for each SOH, and then can transmit it to the battery trading system 63 or the insurance company system 64 through the network 40.

[0149] FIG. 7 is a flowchart showing in detail the process in which the residual value management module 25 according to an embodiment of the present invention evaluates and transmits the residual value of a battery.

[0150] Referring to FIG. 7, the residual value management module 25 determines whether a battery residual value evaluation request is received together with a battery identification code from the battery trading system 63 or the insurance company system 64 through the network 40 at step S240.

[0151] When it is determined that the battery residual value evaluation request is received, the residual value management module 25 determines the current SOH of the battery from the SOH history DB 32 through the database server 30 using the battery identification code at step S260.

[0152] On the other hand, if the reception of the battery residual value evaluation request is not confirmed, the residual value management module 25 suspends the process progress during the time period ΔT, and when ΔT elapses, returns the process to step S240.

[0153] After step S260, proceed to step S270.

[0154] At step S270, the residual value management module 25 queries the pre-defined residual value information for each SOH through the database server 30 using the battery model code included in the battery identification code to determine the residual value of the battery corresponding to the SOH of the battery. The residual value can be shown as the ratio of the current value to the initial value of the battery. The residual value information for each SOH can be pre-stored in the lookup DB 34 in the format of a lookup table. Desirably, the residual value information for each SOH is generated so as to be classified by the battery model code and can be pre-stored in the lookup DB 34.

[0155] Also, at step S280, the residual value management module 25 transmits the battery residual value information to the battery trading system 63 or the insurance company system 64 that requested the battery residual value information through the network 40.

[0156] In addition, the residual value management module 25 may store in the charging DB 36 the identification code of the battery trading system 63 or the insurance company system 64 to which the battery residual value has been transmitted at step S290, a time stamp including the transmission time, and transaction charging information including charging.

[0157] The battery trading system 63 may provide an e-commerce website through the network 40. The e-commerce website provides a distribution channel through which a used battery distribution company or an electric vehicle shareholder can sell used batteries online.

[0158] Preferably, the company operating the battery trading system 63 can receive used batteries from a used battery distribution company, have them evaluated by the platform service system 10 for their residual value, and then determine and sell the price of the batteries based on the residual value.

[0159] During the process in which the used battery is registered on the e-commerce website for sales purposes, the battery trading system 63 can query the platform service system 10 according to the present invention for the residual value of the battery and receive the transmission. The residual value of the battery transmitted from the platform service system 10 can be utilized by the battery trading system 63 to calculate the price of the used battery. In one example, the battery trading system 63 can determine the price of the used battery in proportion to the residual value of the battery and provide used battery sales information through the e-commerce website.

[0160] The insurance company system 64 can provide an insurance enrollment website through the network 40. The insurance enrollment website can provide services so that users of used electric vehicles can enroll in auto insurance online.

[0161] During the process of accepting insurance enrollment for a used electric vehicle, the insurance company system 64 can receive a battery identification code from the user and query the platform service system 10 according to the present invention for the residual value of the battery and receive the transmission. The insurance company system 64 can determine the residual value of the used electric vehicle using the residual value of the battery provided by the platform service system 10 and the mileage of the used electric vehicle input by the user, and calculate the insurance premium for the used electric vehicle based on this. Here, it is obvious that the higher the residual value of the battery, the higher the residual value of the used electric vehicle will be determined.

[0162] According to still another aspect of the present invention, the platform service system 10 can provide a quality assurance (warranty) service for batteries whose battery reuse grades have been continuously managed from the stage of electric vehicle shipment.

[0163] That is, any server or any system can transmit a battery quality guarantee request together with a battery identification code to the platform service system 10 through the network 40.

[0164] Then, when the platform service system 10 queries the SOH history DB 32 through the database server 30 using the battery identification code and confirms that the management of the reuse level has been continuously maintained for the battery from 100% SOH, it transmits a warranty message to the server or system that requested the battery quality guarantee, and can generate billing information including the identification code of the server or system for the transaction and record it in the billing DB 36.

[0165] According to the present invention, by providing an integrated management model related to the reuse of the battery mounted on an electric vehicle, the residual value can be maximally utilized until the battery is shipped out and discarded. Also, by estimating the SOH for the battery that has entered the reuse stage and continuously managing the reuse level by the platform service system, integrated management can be performed over the entire usage cycle of the battery. Also, since the SOH is managed over the entire usage cycle of the battery by the platform service system, the reliability and accuracy of the battery residual value can be improved. Also, by utilizing the battery residual value calculated based on accurate SOH information for calculating the transaction price of a used electric vehicle (battery) or calculating the insurance premium of a used electric vehicle, the used electric vehicle trading market can be activated. Also, the present invention enables the implementation of a new concept business of battery quality guarantee service.

[0166] In the present invention, at least one or more of the control logics executed by each module included in the platform server 20 are combined, and the combined control logic is created in a computer-readable code system and can be recorded on a computer-readable recording medium. The type of the recording medium is not particularly limited as long as it can be accessed by a processor included in the computer. As an example, the recording medium includes at least one or more selected from the group including ROM, RAM, register, CD-ROM, magnetic tape, hard disk, floppy disk, and optical data recording device. Further, the code system can be distributed and stored and executed in computers connected by a network. Also, functional programs, codes, and code segments for implementing the combined control logic can be easily inferred by a programmer in the technical field to which the present invention belongs.

[0167] In describing various embodiments of the present invention, components named "~module" should be understood as functionally divided elements rather than physically divided elements. Therefore, each component can be selectively integrated with other components, or each component can be divided into sub-components for efficient execution of the control logic. However, it should be obvious to those skilled in the art that if the identity of the function is recognized even when the components are integrated or divided, the integrated or divided components should also be interpreted as being within the scope of the present invention.

[0168] As described above, the present invention has been described with reference to limited examples and drawings, but the present invention is not limited thereto, and it goes without saying that various modifications and variations are possible within the equivalent scope of the technical idea and claims of the present invention by those having ordinary knowledge in the technical field to which the present invention belongs.
