Effect of the Invention

[0022] According to one embodiment of the present disclosure, unauthorized battery replacement from a vehicle can be more effectively detected. [Brief description of the drawings]

[0023] [Figure 1] FIG. 1 is a diagram showing an overview of a determination system according to an embodiment. [Diagram 2] 2 is a block diagram showing an example of the configuration of the information processing device shown in FIG. 1; [Diagram 3] FIG. 1 is a diagram illustrating an example of the configuration of a determination system according to an embodiment. [Figure 4] FIG. 2 is a diagram for explaining an example of measurement of physical properties of a battery. [Diagram 5] FIG. 4 is a diagram illustrating an example of a vehicle DB. [Figure 6] FIG. 13 is a diagram illustrating an example of a battery DB. [Figure 7] FIG. 1 is a diagram illustrating an example of the configuration of a determination system according to an embodiment. [Figure 8]10 is a flowchart showing an example of the operation of the determination system. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] <Comparative Example> As an example of a comparative example, Patent Document 1 (Claim 1) describes a battery type determination device comprising: "an output control unit that instructs a current application circuit to apply a specific current to a target battery; a voltage response measurement unit that measures the voltage response of the target battery to the current applied by the output control unit; a calculation unit that determines an inductance value of the target battery based on the current value applied by the output control unit and the voltage value measured by the voltage response measurement unit; and a determination unit that determines the type of the target battery based on a specified value of inductance according to the type of the target battery and the inductance value of the target battery determined by the calculation unit."

[0025] Patent document 2 (claim 1) describes a battery management system comprising: "a first management device that manages battery characteristics measured under specified conditions for each of a plurality of batteries that can be installed in a mobile body powered by a battery, by linking the battery characteristics to identification information for each battery; and a second management device that, when the first battery installed in the mobile body is replaced with a second battery, compares the battery characteristics of the second battery measured under the specified conditions in the mobile body with the battery characteristics linked to the identification information of the second battery in the first management device, and if the comparison fails, prohibits use of the second battery in the mobile body."

[0026] However, the configuration according to the comparative example has room for improvement in effectively detecting unauthorized battery replacement when the battery is illegally replaced while the vehicle driven by the battery is being rented. For example, the secondary battery installed in an xEV accounts for the majority of the vehicle body cost. Therefore, there is a risk that the secondary battery will be swapped for a non-genuine product of poor quality. In particular, xEVs used for lease and rental purposes are often used by an unspecified number of people other than the owner, and there is a high risk of non-genuine products being mixed in. The present disclosure aims to provide a highly versatile system that identifies the type of in-vehicle secondary battery and determines its authenticity in order to quickly grasp such a situation.

[0027] <Embodiment> Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. In each drawing, parts having the same configuration or function are denoted by the same reference numerals. In the description of this embodiment, duplicated descriptions of the same parts may be omitted or simplified as appropriate.

[0028] 1 is a diagram showing an overview of a determination system 1a according to an embodiment. The determination system 1a determines the authenticity of a battery 41 mounted on a vehicle 40. The vehicle 40 is an electric vehicle that is driven by the electric energy of the battery 41. The vehicle 40 may include, for example, a BEV (Battery Electric Vehicle), a HEV (Hybrid Electric Vehicle), and a PHEV (Plug in Hybrid Electric Vehicle) (these electric vehicles are collectively referred to as "xEV").

[0029] The determination system 1a includes an information processing device 10, a camera 21, a physical property sensor 22, and a vehicle information DB (Database) 30. Hereinafter, the determination systems 1a, 1b, and 1c may be collectively referred to as a "determination system 1." The information processing device 10 is connected to the camera 21, the physical property sensor 22, and the vehicle information DB (Database) 30 so as to be able to communicate with each other.

[0030] Camera 21 photographs vehicle 40 to obtain an image. Camera 21 may be, for example, a digital camera. The image is used to obtain information necessary to identify vehicle 40, such as the vehicle identification number, vehicle type, manufacturer, model (generation), grade, and license plate number information. Camera 21 may obtain one or more images including, for example, the license plate, a portion of vehicle 40 on which the vehicle identification number is written, and an external appearance that allows the body shape of vehicle 40 to be identified. Camera 21 may obtain images not only of vehicle 40, but also of a document on which information necessary to identify vehicle 40 is written, such as a vehicle inspection certificate.

[0031] The physical property sensor 22 measures the physical properties of a battery 41 (target battery) mounted on the vehicle 40. The physical property sensor 22 is, for example, a magnetic sensor that measures leakage magnetic flux formed around the battery 41, but is not limited to this. For example, the physical property sensor 22 may be an ultrasonic sensor or a current sensor. In addition, the physical property sensor 22 may be a sensor that can measure, for example, current characteristics or changes in an external magnetic field accompanying charging and discharging of the battery 41, sound wave reflection characteristics derived from the structure of the battery 41, or the internal solvent material of the battery 41 and its distribution, etc.

[0032] The vehicle information DB30 stores a correspondence relationship between a vehicle ID (vehicle identification information) that identifies the vehicle 40 and a battery ID (battery identification information) that identifies the battery 41. In the example of FIG. 1, the vehicle information DB30 indicates the correspondence relationship between vehicle model and battery type as well as vehicle ID and battery ID. In FIG. 1, the vehicle information DB30 is provided outside the information processing device 10, but at least a part of the functions of the vehicle information DB30 may be provided in the information processing device 10. The vehicle information DB30 may be configured with multiple DBs (for example, vehicle DBs 121 (121a, 121b) and battery DBs 123 (123a, 123b) described later with reference to FIGS. 3 and 7) according to the type of information.

[0033] The information processing device 10 determines the authenticity of a battery 41 mounted on a vehicle 40. The information processing device 10 is, for example, a computer such as a PC (Personal Computer), a WS (Workstation), or a tablet terminal. The information processing device 10 includes an analysis unit 101 and a matching unit 102. The analysis unit 101 analyzes an image acquired by the camera 21 and the physical properties of the battery 41 measured by the physical property sensor 22. The matching unit 102 matches a battery ID corresponding to a vehicle ID acquired by analyzing the image with a battery ID acquired by analyzing the physical properties of the battery 41, and determines the authenticity of the battery 41. As will be described later, the analysis unit 101 and the matching unit 102 may be realized by software.

[0034] In the above configuration, the information processing device 10 acquires a vehicle ID for identifying the vehicle 40 based on an analysis of an image acquired by the camera 21 and an input of information for identifying the vehicle 40 from a user. The information processing device 10 acquires a first battery ID (first battery identification information) for identifying the battery 41 corresponding to the acquired vehicle ID by referring to the vehicle information DB 30 or the like. The information processing device 10 acquires physical properties of the battery 41 mounted on the vehicle 40, and acquires a second battery ID (second battery identification information) for identifying the battery 41 corresponding to the acquired physical properties by referring to the vehicle information DB 30 or the like. The information processing device 10 compares the first battery ID with the second battery ID to determine the authenticity of the battery 41 mounted on the vehicle 40, and outputs a determination result of the authenticity of the battery 41.

[0035] In this way, the determination system 1 determines the authenticity of the battery 41 by comparing the battery ID corresponding to the vehicle ID for identifying the vehicle 40 with the battery ID specified based on the physical properties of the battery 41. Therefore, the determination system 1 can effectively determine whether the battery 41 installed in the vehicle 40 has been fraudulently replaced.

[0036] Fig. 2 is a block diagram showing a configuration example of the information processing device 10 in Fig. 1. The information processing device 10 is one or more computer devices capable of communicating with each other. As shown in Fig. 2, the information processing device 10 includes a control unit 11, a storage unit 12, a communication unit 13, an input unit 14, and an output unit 15.

[0037] The control unit 11 includes one or more processors. In one embodiment, the "processor" is a general-purpose processor or a dedicated processor specialized for a specific process, but is not limited thereto. The control unit 11 is communicably connected to each component of the information processing device 10, and controls the operation of the information processing device 10 as a whole.

[0038] The storage unit 12 includes any storage module such as a hard disk drive (HDD), a solid state drive (SSD), a read-only memory (ROM), and a random access memory (RAM). The storage unit 12 may function as a main storage device, an auxiliary storage device, or a cache memory. The storage unit 12 stores any information used in the operation of the information processing device 10. For example, the storage unit 12 may store a system program, an application program, and various information received by the communication unit 13. The storage unit 12 is not limited to being built into the information processing device 10, and may be an external database or an external storage module. For example, the storage unit 12 may store an image acquired by the camera 21 and a measurement value of a physical property acquired by the physical property sensor 22.

[0039] The communication unit 13 includes any communication module capable of communicating with other devices such as a scanner by any communication technology. The communication unit 13 may further include a communication control module for controlling communication with other devices, and a storage module for storing communication data such as identification information required for communication with other devices. For example, the communication unit 13 may communicate with the camera 21, the physical property sensor 22, and the vehicle information DB 30.

[0040] The input unit 14 includes one or more input interfaces that receive an input operation by an operator and acquire input information based on the operation by the operator. For example, the input unit 14 is a physical key, a capacitive key, a pointing device, a touch screen that is integrated with the display of the output unit 15, a microphone that receives voice input, or the like, but is not limited to these.

[0041] The output unit 15 includes one or more output interfaces that output information to the operator and notify the operator. For example, the output unit 15 is a display that outputs information as an image, or a speaker that outputs information as sound, but is not limited to these. Such a display may be, for example, a liquid crystal panel display or an organic EL (Electro Luminescence) display. At least one of the input unit 14 and the output unit 15 may be configured integrally with the information processing device 10, or may be provided separately.

[0042] The functions of the information processing device 10 (for example, the analysis unit 101 and the collation unit 102) can be realized by executing a computer program (program) according to this embodiment on a processor included in the control unit 11. That is, the functions of the information processing device 10 can be realized by software. The computer program causes a computer to execute the processing of steps included in the operation of the information processing device 10, thereby causing the computer to realize the functions corresponding to the processing of each step. That is, the computer program is a program for causing a computer to function as the information processing device 10 according to this embodiment. The computer program may be recorded on a computer-readable recording medium. Programs include information used for processing by an electronic computer and equivalent to a program. For example, data that is not a direct instruction to a computer but has the property of defining computer processing corresponds to "something equivalent to a program."

[0043] A part or all of the functions of the information processing device 10 may be realized by a dedicated circuit included in the control unit 11. That is, a part or all of the functions of the information processing device 10 may be realized by hardware. Furthermore, the information processing device 10 may be realized by a single computer, or may be realized by cooperation of multiple computers.

[0044] FIG. 3 is a diagram showing an example of the configuration of a determination system 1b according to an embodiment. As described above, at least a part of the functions of the vehicle information DB 30 may be provided in the information processing device 10a. In the determination system 1b of FIG. 3, the vehicle information DB 30 is provided in the collation unit 102a of the information processing device 10a as a vehicle DB 121a and a battery DB 123a. In FIG. 3, the information processing device 10a includes an analysis unit 101a and a collation unit 102a. The analysis unit 101a includes a vehicle number acquisition unit 111, a vehicle type acquisition unit 112, and a feature amount acquisition unit 113. The collation unit 102a includes a vehicle DB 121a, a vehicle ID identification unit 122, a battery DB 123a, a battery ID identification unit 124, and a determination unit 125.

[0045] The vehicle identification number acquisition unit 111 analyzes the image acquired by the camera 21 to acquire the vehicle identification number of the vehicle 40. Specifically, the vehicle identification number acquisition unit 111 may analyze a captured image of a vehicle inspection certificate on which the vehicle identification number is written, or a captured image of a part of the vehicle 40 on which the vehicle identification number is engraved, to acquire the vehicle identification number.

[0046] The vehicle type acquisition unit 112 analyzes the image captured by the camera 21 to acquire the vehicle type of the vehicle 40. Specifically, the vehicle type acquisition unit 112 may acquire an automobile type classification, such as a passenger car or a small freight vehicle, as the vehicle type of the vehicle 40. The vehicle type acquisition unit 112 may analyze captured images of external features such as the exterior of the vehicle 40, emblems, and vehicle inspection certificates, etc., to acquire the vehicle type. The vehicle type may also include information such as the model (generation), grade, and manufacturer.

[0047] The analysis unit 101a may acquire specific information for identifying the vehicle 40 other than the vehicle number and the vehicle model based on the image acquired by the camera 21. For example, the analysis unit 101a may analyze an image of the vehicle 40 captured by the camera 21 to extract a number sequence and a character string in the license plate as the specific information. Alternatively, the analysis unit 101a may acquire information such as the model (generation) and grade as the specific information. The analysis unit 101a may acquire information for identifying the vehicle 40 without based on the image acquired by the camera 21. For example, the information processing device 10a may connect to an OBD (On Board Diagnostics) of the vehicle 40 via an interface or a scan tool and acquire information for identifying the vehicle 40 from the OBD. As will be described later with reference to FIG. 7, the information processing device 10a may receive an input of information for identifying the vehicle 40 from a user.

[0048] Furthermore, the analysis unit 101a may issue an alert to the user when the vehicle identification number, vehicle model, or other specific information of the vehicle 40 cannot be acquired based on the image of the camera 21. Specifically, the analysis unit 101a may display an image indicating that the vehicle identification number, vehicle model, or other specific information of the vehicle 40 has failed to be acquired on the display of the output unit 15, or may output an alarm sound from the speaker of the output unit 15. Furthermore, when the analysis unit 101a cannot acquire the vehicle identification number, vehicle model, or other specific information of the vehicle 40, it may acquire an image again using the camera 21. When acquiring an image again, the analysis unit 101a may display a guide on the display of the output unit 15 on the shooting method of the camera 21 to acquire a better image.

[0049] Fig. 4 is a diagram for explaining an example of physical property measurement of a battery 41. Fig. 4 shows a horizontal plane obtained by observing the bottom surface of a vehicle 40 from vertically below. As illustrated in Fig. 4, the battery 41 has cells 411 arranged in a lattice pattern on the horizontal plane. As shown in Fig. 4, the physical property sensor 22 may measure the magnetic flux while scanning the cells 411 row by row along the scanning direction 29, and obtain the spatial distribution of the magnetic flux formed around the battery 41.

[0050] The feature amount acquiring unit 113 acquires the feature amount from the measurement value of the physical property of the battery 41 acquired by the physical property sensor 22. For example, when the feature amount acquiring unit 113 acquires the measurement value of the leakage magnetic flux formed around the battery 41, the feature amount acquiring unit 113 may acquire information on the spatial frequency, amplitude, etc. of the leakage magnetic flux as the feature amount.

[0051] The vehicle DB 121a (the same applies to the vehicle DB 121b described later with reference to FIG. 7) is a database indicating the correspondence between information for identifying the vehicle 40 and the vehicle ID and the battery ID. FIG. 5 is a diagram showing an example of the vehicle DB 121 (121a, 121b).

[0052] In FIG. 5, "manufacturer" is the manufacturer that produced vehicle 40. "Vehicle type" is a classification of the type of automobile, such as a regular passenger car or a small freight car. "Model" is a classification index designated for automobiles with the same structure, equipment, and performance. "Model" may be expressed, for example, as an identification symbol given by a combination of letters and numbers to classify the make and model of an automobile.

[0053] The "lot number" is a number (serial number) given to each production unit of vehicle 40 of the same specifications. The "vehicle number" is an individual identification number given by the Ministry of Land, Infrastructure, Transport and Tourism upon notification from the manufacturer of vehicle 40 and assigned to each vehicle 40.

[0054] The "vehicle ID" is identification information that uniquely identifies the vehicle 40 in the determination system 1. In this embodiment, the "vehicle ID" is unique identification information that is different from other information such as the "vehicle number" and the "lot number", but it may be the same as the other information such as the "vehicle number" and the "lot number" or a combination of these.

[0055] The "battery ID" is identification information that identifies the battery 41 mounted on the vehicle 40. In this embodiment, the "battery ID" is unique information different from that of the battery 41, such as a serial number, but it may be the same as other information such as a serial number or a combination of these.

[0056] The vehicle ID identification unit 122 refers to the vehicle DB 121a to acquire the vehicle ID and the battery ID that correspond to the identification information for identifying the vehicle 40 acquired by the vehicle identification number acquisition unit 111 and the vehicle type acquisition unit 112.

[0057] The battery DB 123a (the same applies to a battery DB 123b described later with reference to FIG. 7) is a database indicating the correspondence between feature amounts related to the physical properties of the battery 41 and the battery ID. FIG 6 is a diagram showing an example of the battery DB 123 (123a, 123b).

[0058] 6, a "magnetic waveform" is a spatial magnetic waveform when the physical property sensor 22 is operated around the cell 411 along the scanning direction 29 in FIG.

[0059] The "feature amount" is a value obtained by analyzing the measured value of the physical property sensor 22. For example, the "feature amount" is information on the spatial frequency and amplitude of the leakage magnetic flux. In FIG. 6, for example, T 1 , T 2 , and T 3 is the spatial frequency at which the peak is observed. 2 is the square of the amplitude of the leakage flux.

[0060] "Battery type" is the type of battery 41. For example, "battery type" may be a number (serial number) of the battery 41 given to each production unit.

[0061] The "battery ID" is identification information for identifying the battery 41. In this embodiment, the meaning of the "battery ID" on the vehicle DB 121 (121a, 121b) is the same as the meaning of the "battery ID" on the battery DB 123 (123a, 123b).

[0062] The battery ID specification unit 124 refers to the battery DB 123 a to acquire a battery ID corresponding to the characteristic amount of the physical property of the battery 41 acquired by the characteristic amount acquisition unit 113 .

[0063] The determination unit 125 compares the battery ID (first battery ID) linked to the vehicle 40 identified by the vehicle ID identification unit 122 with the battery ID (second battery ID) acquired based on an analysis of the physical properties of the battery 41 identified by the battery ID identification unit 124 to determine the authenticity of the battery 41. If the first battery ID and the second battery ID match, the determination unit 125 determines that the battery 41 installed in the vehicle 40 is genuine, and if not, determines that the battery is not genuine.

[0064] The information processing device 10a outputs the determination result of the determination unit 125. In the example of Fig. 3, the information processing device 10a causes the display unit 103 of the output unit 15 to display the determination result of the authenticity of the battery 41, and outputs the determination result.

[0065] In this embodiment, each of the functional elements described with reference to FIG. 3 is realized by software, but at least a part of these functional elements may be configured by dedicated hardware.

[0066] The configuration of the determination system 1 described with reference to Fig. 1 and Fig. 3 is an example, and various modified examples are possible. Fig. 7 is a diagram showing an example of the configuration of a determination system 1c according to an embodiment. In the determination system 1c, the analysis unit 101b includes a feature acquisition unit 113. The matching unit 102b includes a vehicle ID identification unit 122, a battery ID identification unit 124, and a determination unit 125.

[0067] 7 does not include a camera 21, but instead includes an operation unit 23 that receives operations from a user. The operation unit 23 may be configured with the input unit 14. The determination system 1c prompts the user to input identification information for identifying the vehicle 40, obtains a vehicle ID and a battery ID corresponding to the input identification information, and outputs them to the determination unit 125.

[0068] In addition, the determination system 1c does not include the vehicle DB 121b and the battery DB 123b in the information processing device 10b, but includes them in a cloud or the like that can communicate with the information processing device 10b. The information processing device 10b accesses the vehicle DB 121b and the battery DB 123b via a network including the Internet as necessary.

[0069] The determination unit 125 compares a battery ID (first battery ID) linked to the identification information for identifying the vehicle 40 input by the user with a battery ID (second battery ID) linked to the characteristic amount of the physical properties of the battery 41 acquired by the physical property sensor 22. If the first battery ID and the second battery ID match, the determination unit 125 determines that the battery 41 installed in the vehicle 40 is genuine, and if not, determines that the battery is not genuine. The determination unit 125 outputs the determination result to the recording unit 131. The recording unit 131 is an external storage device. The recording unit 131 may be, for example, a USB (Universal Serial Bus) memory, a network storage, or the like.

[0070] Fig. 8 is a flowchart showing an operation example of the determination system 1. Fig. 8 is a flowchart showing the operation of the information processing device 10 of Fig. 1. The operation of the information processing device 10 described with reference to Fig. 8 may correspond to one of the determination methods of the information processing device 10. The operation of each step in Fig. 8 may be executed based on the control by the control unit 11 of the information processing device 10.

[0071] In step S1, the control unit 11 acquires a vehicle ID (vehicle identification information) for identifying the vehicle 40. Specifically, the control unit 11 may acquire the vehicle ID by analyzing an image obtained by photographing the vehicle 40 or by accepting input of identification information for identifying the vehicle 40 from a user.

[0072] In step S2, the control unit 11 acquires a first battery ID that is identification information of the battery 41 corresponding to the vehicle ID acquired in step S1. Specifically, the control unit 11 may refer to the vehicle DB 121 (121a, 121b) and acquire the battery ID corresponding to the vehicle ID as the first battery ID.

[0073] In step S3, the control unit 11 acquires physical properties of the target battery, which is the battery 41 mounted on the vehicle 40. Specifically, the control unit 11 controls the physical property sensor 22 to acquire measurement values ​​of the physical properties of the battery 41, such as leakage magnetic flux.

[0074] In step S4, the control unit 11 acquires a second battery ID that is identification information of the battery 41 corresponding to the physical properties of the target battery (battery 41). Specifically, the control unit 11 may acquire a characteristic amount of the physical properties of the target battery, and refer to the battery DB 123 (123a, 123b) to acquire a battery ID corresponding to the characteristic amount as the second battery ID.

[0075] In step S5, the control unit 11 determines whether the first battery ID acquired in step S2 is the same as the second battery ID acquired in step S4. If the first battery ID and the second battery ID are the same (YES in step S5), the control unit 11 proceeds to step S6, and if not (NO in step S5), the control unit 11 proceeds to step S7.

[0076] In step S6, the control unit 11 determines that the battery 41 (target battery) mounted on the vehicle 40 is genuine.

[0077] In step S7, the control unit 11 determines that the battery 41 (target battery) installed in the vehicle 40 is not genuine.

[0078] In step S8, control unit 11 outputs the determination result acquired in step S6 or step S7. Specifically, control unit 11 may display the determination result of the authenticity of the target battery on display unit 103 of output unit 15, or output the determination result to memory unit 12 or recording unit 131. Upon completing the process of step S8, control unit 11 ends the process of the flowchart.

[0079] As described above, the information processing device 10 acquires a vehicle ID that identifies the vehicle 40, and acquires a first battery ID that identifies the battery 41 that corresponds to the acquired vehicle ID. The information processing device 10 acquires physical properties of the battery 41 mounted on the vehicle 40, and acquires a second battery ID that identifies the battery 41 that corresponds to the acquired physical properties. The information processing device 10 compares the first battery ID with the second battery ID to determine the authenticity of the battery 41 mounted on the vehicle 40, and outputs the authenticity determination result.

[0080] In this way, the information processing device 10 determines the authenticity of the battery 41 installed in the vehicle 40 by comparing the first battery ID corresponding to the vehicle ID with the second battery ID corresponding to the physical properties of the battery 41. Therefore, the information processing device 10 can effectively determine whether the battery 41 installed in the vehicle 40 has been fraudulently replaced.

[0081] Furthermore, the information processing device 10 may acquire an image of the vehicle 40, and acquire the vehicle ID based on the analysis result of the acquired image. In this way, the information processing device 10 acquires the vehicle ID based on the analysis result of the image of the vehicle 40, and determines the authenticity of the battery 41, so that it is possible to effectively detect whether the battery 41 has been illegally replaced in the vehicle 40.

[0082] Furthermore, the information processing device 10 may receive, from the user, input of identification information for identifying the vehicle 40, and acquire the vehicle ID based on the identification information whose input has been received.

[0083] In one embodiment, the information processing device 10 may acquire a measurement value of leakage magnetic flux of the battery 41 as a physical property of the battery 41. In this way, the information processing device 10 acquires the measurement value of leakage magnetic flux of the battery 41 to determine the authenticity of the battery 41, making it difficult to illegally replace the battery 41 without revealing that the battery 41 is not genuine. Therefore, the information processing device 10 can effectively detect illegal replacement of the battery 41.

[0084] As described above, the determination system 1 identifies the vehicle 40 using the camera 21 or the like, and acquires information for identifying the type and individual battery 41 that should originally be installed. Meanwhile, the determination system 1 is configured to acquire information for identifying the type and individual battery 41 by measuring the physical properties of the battery 41 from outside the vehicle 40. The determination system 1 compares the first battery ID corresponding to the vehicle ID that identifies the vehicle 40 with the second battery ID corresponding to the physical properties of the battery 41 to detect unauthorized replacement of the battery 41.

[0085] When actually using xEVs for business purposes through leasing and rental, the infrastructure varies depending on each operating body. In particular, it is a challenge in terms of cost and operation to suppress new investments as much as possible to ensure the security of the battery 41 for each vehicle 40. Therefore, it is desirable to be able to reuse existing facilities, information, and equipment.

[0086] In order to enable the determination system 1 according to the present disclosure to be connected to existing facilities and devices at low cost and with high versatility, the determination system 1 according to the present disclosure separates a configuration for acquiring a battery ID from the physical properties of the battery 41 from a configuration for determining the authenticity of the battery 41 by comparing the battery ID corresponding to the vehicle 40. Therefore, according to the present disclosure, it is possible to acquire information required for comparison and determination from outside, ensuring scalability.

[0087] The present disclosure is not limited to the above-mentioned embodiment. For example, multiple blocks described in the block diagram may be integrated, or one block may be divided. Multiple steps described in the flowchart may be executed in parallel or in a different order according to the processing capacity of the device executing each step, or as necessary, instead of being executed in chronological order according to the description. For example, in FIG. 8, the control unit 11 may execute the processing of steps S1 and S2 after executing the processing of steps S3 and S4. Alternatively, for example, the control unit 11 may execute the processing of steps S2 and S4 after executing the processing of steps S1 and S3. Also, for example, the control unit 11 may execute the processing of steps S3 and S4 in parallel with the processing of steps S1 and S2. Other modifications are possible within the scope of the present disclosure. [Explanation of symbols]
