Description

Battery pack identification system, battery pack identification apparatus, battery pack identification label, and battery pack identification method

[0001] The present disclosure relates to a battery pack identification system, a battery pack identification apparatus, a battery pack identification label, and a battery pack identification method.

[0002] Battery packs using rechargeable secondary batteries such as lithium ion secondary batteries are used in a wide range of applications. It is desired that such battery packs be collected after use and utilized for recycling or the like. On the other hand, in order to manage the model, manufacturing number, etc. of the battery pack, identification information for identifying the battery pack is stored in E 2 PROM, and technologies for storing the same have been proposed (e.g., Patent Documents 1 and 2).

[0003] However, in this method, for each battery pack, E 2 PROM needs to be provided, which causes problems of complicated configuration and high cost. In contrast, printing the manufacturing number on the battery pack or attaching a QR code (registered trademark) encoded with the manufacturing number can be considered. With this method, identification information can be individually attached to the battery pack at extremely low cost. However, since QR codes are widely popularized, anyone can easily read and analyze them, which poses a risk of information leakage and the like.

This is a schematic diagram showing an example of the same homepage and site to which a general user and a cryptographer are directed.

[0012] The form of this disclosure may be specified by the following configurations and features. A battery pack identification system according to one embodiment of this disclosure comprises a battery pack including a secondary battery, an identification label affixed to the battery pack containing identification information that identifies the battery pack, the code being encrypted with a predetermined algorithm, and an identification device capable of decoding the code contained in the identification label, wherein at least a portion of the identification information is encrypted in the code, and the identification device is capable of decrypting the information encrypted in the code. With the above configuration, identification information can be individually assigned at low cost by recording the identification information of the battery pack on the identification label, while security can be enhanced by encrypting the identification information so that it cannot be easily read.

[0013] In addition to the above embodiment, a battery pack identification system according to another embodiment of this disclosure allows the identification device to execute a decryption program capable of decrypting information encrypted in a code. With this configuration, by executing the decryption program, the identification device can correctly read the identification information of the battery pack, thereby enhancing security by making it difficult for unauthorized third parties to decrypt the information, while still allowing the collection of necessary information.

[0014] In addition to the above embodiments, battery pack identification systems according to other embodiments of the present disclosure may be configured such that, when the code is decoded according to a standardized coding protocol, predetermined dummy information is obtained. This configuration prevents the leakage of battery pack identification information by providing dummy information to third parties who do not have the equipment to decode it.

[0015] In addition to the above embodiments, battery pack identification systems according to other embodiments of this disclosure may include URL information that directs to a predetermined homepage as predetermined dummy information. With this configuration, if a third party without decryption equipment decodes the information, they will be directed to a predetermined homepage, thus concealing the fact that dummy information has been provided without the third party being aware of it.

[0016] In addition to the above embodiment, a battery pack identification system according to another embodiment of this disclosure includes, as described above, predetermined dummy information, URL information that directs to a predetermined homepage and encrypted identification information. The identification device decrypts the encrypted identification information and adds it to the URL information, thereby enabling the display of the decrypted identification information on the predetermined homepage. With this configuration, the correct identification information can be displayed by decrypting it through the identification device, and the content displayed can be switched between a legitimate user with an identification device and a third party, even while using a common homepage.

[0017] In addition to the above embodiments, battery pack identification systems according to other embodiments of this disclosure can perform encryption using a public key scheme. This configuration has the advantage that the identification information contained in the code can be easily encrypted, and the identification information can be kept secret with a private key for decryption.

[0018] In addition to the above embodiments, battery pack identification systems according to other embodiments of this disclosure may use a two-dimensional code or RFID for the identification label. The identification label may include an IC tag. The above configuration has the advantage of ensuring ease of encoding and decoding, and confidentiality of identification information, by appropriately utilizing a variety of codes, etc.

[0019] In addition to the above embodiments, battery pack identification systems according to other embodiments of this disclosure can use QR codes (registered trademark) as the code. With this configuration, a QR code reader can be used, encoding and decoding can be easily performed, and identification information can be kept confidential by including encryption in the QR code.

[0020] Another embodiment of the battery pack identification device according to the present disclosure is a battery pack identification device for decoding and reading a code encoded according to a standardized coding protocol, which contains identification information that identifies the battery pack and is included in an identification label affixed to the battery pack including a secondary battery, wherein at least a portion of the identification information is encrypted using a predetermined algorithm, and the encrypted information in the code is decryptable. With the above configuration, by recording the identification information of the battery pack on the identification label, identification information can be individually assigned at low cost, while security can be enhanced by encrypting the identification information so that it cannot be easily read.

[0021] A battery pack identification label according to another embodiment of the present disclosure is a battery pack identification label for affixing to a battery pack including a secondary battery, which includes identification information that identifies the battery pack, and includes a code encoded according to a standardized coding protocol, wherein at least a portion of the identification information is encrypted using a predetermined algorithm, and the encrypted information in the code can be decrypted by reading it with a specific identification device. With the above configuration, by recording the identification information of the battery pack on the identification label, the identification information can be individually assigned at low cost, while security can be enhanced by encrypting the identification information so that it cannot be easily read.

[0022] Another embodiment of the battery pack identification method according to the present disclosure is a method for identifying a battery pack including a secondary battery, comprising the steps of: attaching an identification label to the battery pack containing an identification information that identifies the battery pack, the code encoded according to a standardized coding protocol; and reading the code contained in the identification label with an identification device, decoding the code, decrypting at least a portion of the identification information contained in the code, which is encrypted with a predetermined algorithm, and displaying the identification information. This allows for inexpensive individual assignment of identification information by recording the battery pack identification information on an identification label, while enhancing security by encrypting the identification information so that it cannot be easily read.

[0023] The present disclosure will be described in detail below based on the drawings, etc. In the following description, terms indicating specific directions or positions (e.g., "up," "down," and other terms including these) will be used as needed. The use of these terms is for the purpose of facilitating the understanding of the invention by referring to the drawings, and the meaning of these terms does not limit the technical scope of the present invention. Furthermore, parts with the same reference numerals appearing in multiple drawings indicate the same or equivalent parts or components. The embodiments shown below are concrete examples of the technical concept of the present invention and do not limit the present invention to these. Also, the dimensions, materials, shapes, relative arrangements, etc., of the components described below are intended as examples, and are not intended to limit the scope of the present invention to these unless specifically stated. Furthermore, the content described in one embodiment or example is applicable to other embodiments and examples. Also, the size and positional relationships of the components shown in the drawings may be exaggerated for clarity in the explanation. (Battery Pack Identification System 100)

[0024] The battery pack identification system 100 comprises a battery pack 1 including a secondary battery, an identification label 10 affixed to the battery pack 1 containing identification information that identifies the battery pack 1, encoded according to a standardized coding protocol, and an identification device 20 capable of decoding the code 11 contained in the identification label 10. The battery pack identification system 100 reads the identification information from the identification label 10 affixed to the battery pack 1, and makes information and data related to the battery pack 1 available for acquisition, display, and viewing. (Battery pack 1)

[0025] The battery pack 1 comprises one or more rechargeable batteries. The rechargeable batteries include all rechargeable and dischargeable batteries. These can include lithium-ion batteries, nickel-metal hydride batteries, nickel-cadmium batteries, solid-state batteries, etc., and include known or future-developed rechargeable batteries. This disclosure does not specify the type, shape, size, number, connection, arrangement, structure, or configuration of the rechargeable batteries; for example, cylindrical, prismatic, or pouch-type rechargeable battery cells can be used. Furthermore, the battery pack 1 can incorporate a charge / discharge circuit to limit the charging and discharging of the rechargeable batteries, and a protection circuit that monitors the voltage, current, and temperature of the rechargeable batteries and cuts off the current in case of abnormalities. The battery pack 1 may also have a communication unit for transmitting and receiving identification information and information related to the rechargeable batteries. (Identification label 10)

[0026] The identification label 10 is affixed to the battery pack 1 and contains identification information that identifies the battery pack 1. The identification information includes, for example, the serial number, model number, product name, model information, place of manufacture, date of manufacture, manufacturer name, etc., and an identification ID that identifies each battery pack 1. The user of the identification device 20 can obtain information and data related to the identified battery pack 1 from storage areas such as the database 31 and server 30, and can view it by accessing a designated site, homepage, etc., or by displaying it on the identification device 20. The information related to the battery pack 1 includes, for example, the configuration, structure, model information, number of battery cells, connections, voltage and current of each battery cell, temperature, SOC, SOH, characteristics, performance, and abnormal information of the battery pack 1. The information regarding battery pack 1 is extensive and diverse, including not only unchanging data such as the manufacturing date, but also variable data such as the usage period, usage conditions, and data on deterioration, performance degradation, and changes in condition that may occur due to the usage period and conditions. Furthermore, it includes information on external conditions affecting the battery pack 1, such as compliance with domestic and international laws and regulations, EU regulations, company and industry standards, manuals, replacement methods for compatible secondary batteries, and corrective actions, as well as information on the battery pack 1 under specified conditions, and updated data that is updated as needed. Therefore, the information regarding battery pack 1 is not limited to information at the time of manufacture, and data can be added or corrected as needed. For example, the information regarding battery pack 1 may include the results of performance analysis of collected battery pack 1, remote monitoring data, etc., and can be widely used for battery pack 1 collection, recycling, reuse, rental, remote monitoring, and management. In addition, the identification information may include some or all of the information regarding battery pack 1.

[0027] The identification label 10 consists of identification information and other information, and has an encoded, graphic code 11. The identification label 10 includes a code 11 encoded according to a standardized coding protocol. The identification label 10 has a QR code 12 or any other suitable code (QR code 12, etc.) of a size and shape readable by the identification device 20, and the QR code 12, etc. is affixed or installed on the battery pack 1 in a readable position during or after manufacturing. Affixing includes direct or indirect affixing to the battery pack 1, and also includes affixing to a connecting object such as a tag connected to the battery pack 1, for example.

[0028] Code 11 can include not only one-dimensional codes such as barcodes, but also two-dimensional codes such as QR Code 12 (registered trademark). QR Code 12 is particularly preferred due to its fast response time and high convenience, as it can be read by smartphones and tablets. QR Code 12 can be read by a QR Code 12 reader without requiring user registration, login, or passwords, making it convenient to use. However, the identification device 20, application, etc., may require user registration, login, or passwords. This disclosure does not limit Code 11 to QR Code 12; other two-dimensional codes, such as matrix-type (matrix symbol systems) like DataMatrix and VeriCode, or stack-type (multi-row symbol systems) like PDF417 and CODE49, can also be used. Alternatively, numbers or strings of characters can be directly used as Code 11 instead of codes that require encoding. In this case, Code 11 can be read by OCR. Furthermore, instead of these printed codes 11, an RFID embedded in the identification label 10 can be used as the code 11. In this case, the identification label 10 can be an IC tag.

[0029] Battery pack 1 has an identification label 10, such as a QR code 12, attached to it, on which data containing identification information such as model information related to battery pack 1 is encoded. The identification information includes the identification ID of battery pack 1 and is attached to battery pack 1, eliminating the need for special jigs or tools. However, since the identification information can be read by an unspecified number of people if it is only encoded in a QR code 12, the identification information is not stored directly in the code 11 of the QR code 12, but is stored including an encrypted string, etc. Battery pack 1 encrypts the identification information attached to each battery pack 1 using an encryption key and decrypts it using a decryption key. The encryption key that generates the encrypted string, etc., and the decryption key used for decryption can be a common key or an asymmetric key, etc.

[0030] The identification label 10 encrypts at least a portion of the identification information contained in the code 11 using a predetermined algorithm. The code 11 can have all or part of the identification information encrypted, or it can also encrypt parts other than the identification information. By encrypting the code 11, it is possible to set the code information to be public or private, and only specific devices (identification devices 20) that can decrypt the encryption can display the private portion. By including the code 11 with encrypted identification information, external leakage and display of the identification information can be prevented. The code 11 consists of unencrypted plaintext and encrypted code. The plaintext leads to public information that can be decoded and made public, and the public information can be displayed. The code cannot be read unless the code is decrypted, such as by possessing the encryption key. The code 11 can be included in the code 11 as hidden characters, and is indistinguishable from a normal QR code 12, etc. in appearance, so the encrypted information can be kept secret and forgery and tampering can be prevented. If the code is read by a regular code reader (such as a QR code reader) that does not have encryption decryption capabilities, only the plaintext will be read, making it possible to recognize only the plaintext. The content of the encryption, as well as its existence, will not be revealed, and the existence of confidential information will not be detected.

[0031] This disclosure does not specify an encryption method, and all methods capable of encrypting Code 11 may be used. Encryption methods currently in use and those developed in the future may be used as appropriate. While symmetric-key cryptography, which uses the same key for both encryption and decryption, can be used, this method carries the risk of complete exposure of confidential information if the key is stolen, as a third party can easily decrypt it. Therefore, public-key cryptography, which uses separate keys for encryption and decryption, is a highly secure encryption method. In public-key cryptography, the sender and receiver of information and data each possess different pairs of public and private keys. The public key is necessary for encryption, and the private key is necessary for decryption. In public-key cryptography, the public key used for encryption is made public, while the private key used for decryption is kept private and confidential. The public key is publicly available and can be obtained by exchanging it between the two parties via email prior to transmission, or by downloading it from a public web server. The sender then encrypts the information using the receiver's public key and sends it. The receiver, upon receiving the encrypted information, decrypts it using the private key that the receiver secretly possesses. One method of employing public-key cryptography is PGP (Pretty Good Privacy), which boasts high robustness such as 1024 bits and is widely used because a free version is available. Other methods include PKCS (Public Key Cryptography Standards), SSL (Secure Socket Layer), and S / MIME (Secure / Multipurpose Internet Mail Extensions).

[0032] In public-key cryptography, data encrypted with a public key cannot be decrypted without a private key. Only the recipient can decrypt the data using the private key they possess, preventing third parties from decrypting it and thus preventing information leakage. On the one hand, the public key used for encryption can be shared and managed by multiple parties, while on the other hand, the private key used for decryption can be held only by designated viewers, thus preventing information leakage. In the battery pack identification system 100, the identification label 10 is created using a QR code 12 or the like based on the public key. The private key is held by the identification label 10 and is also obtained by transmission from the server 30 to the identification device 20. The private key can be updated and changed with each transmission, reception, and decryption. The decryption program may include transmission and reception and updates between the server 30 and the identification device 20, or the decryption program may be updated through transmission and reception between the server 30 and the identification device 20. In addition to public-key cryptography, other encryption methods such as symmetric-key cryptography and hybrid cryptography can also be used.

[0033] In this disclosure, encoding and encryption are used as distinct terms. Encoding refers to coding characters, numbers, symbols, etc., or any combination thereof, while decoding refers to returning the code 11 to its pre-encoded state as characters, numbers, symbols, etc., or any combination thereof. Encryption refers to making data or information unreadable, preventing its content from being recognized, revealed, disclosed, accessed, or read without specific predetermined conditions, while decryption refers to making the encrypted content recognizable and readable. Encryption can be implemented, for example, by keeping the algorithm confidential, or by requiring keys, passwords, access, conditions, etc.

[0034] The code 11 of the identification label 10 may include dummy information that does not lead to the identification information. The dummy information can be displayed or directed to a predetermined page, etc., upon reading the code 11. When this code 11 is decoded according to a standardized coding protocol, predetermined dummy information is obtained. The predetermined dummy information may include URL information and can direct to a predetermined site, homepage, top page, etc. The identification device 20 can decrypt the encrypted identification information attached to the URL information and make the decrypted identification information displayable on the predetermined site, homepage, display, etc. The predetermined dummy information can also display "Display, Access Not Possible," etc., to the person who reads the code 11 and accesses it, but it can also direct to a display or destination that makes it difficult for the accesser to recognize that it is dummy information. The code 11 of the identification label 10 includes dummy information including URL information and encrypted encrypted information, and can direct the accesser to different sites, homepages, displays, etc., depending on whether or not the encryption can be decrypted. The encrypted information includes identification information, and when decrypted, the identification information can be displayed or access to the identification information can be made possible. As shown in Figure 2, ordinary users who cannot decrypt the encryption can be directed to general site 32, and only cryptanalysts who can decrypt the encryption using the identification device 20 can be directed to browsing site 33 where they can view the identification information. Ordinary users can view general site 32, but they cannot view or display browsing site 33 and therefore cannot access the identification information. General site 32 is made to be indistinguishable from browsing site 33 at first glance, so that ordinary users who decode code 11 and access general site 32 cannot recognize, or have difficulty recognizing, that it is dummy information.

[0035] Furthermore, the URL information allows for different access to the same site, homepage (top page), while still guiding general users who cannot decrypt the encryption and cryptanalysts who can decrypt the encryption using the identification device 20 to the same site. General users cannot view the encrypted portion containing identification information, but can view other publicly available portions and pages. Cryptanalysts can view the decrypted identification information. Cryptanalysts can view all pages of the site containing identification information. This configuration eliminates the need to create a separate site, allows general users to access the designated legitimate site, and prevents the leakage of identification information by preventing general users from viewing it. General users can be shown and disclosed publicly available company information, product descriptions, advertisements, etc. General users are unaware that identification information exists on the site, thus protecting the identification information without creating unnecessary risks. For example, for general users, identification information is not displayed, and the tab 34, display, button, etc. that display the identification information does not appear, or the tab 34, display, button, etc. that access the page to be displayed does not appear, making it impossible to display the identification information and making it impossible to click or access it. As shown in Figure 3, the browsing site 33 has, for example, a tab 34 that displays the identification information shown by the dotted line in the figure, a tab 34 that opens the page to be displayed, a display, etc. (in Figure 3), while the general site 32 does not have a tab 34, display, etc. that displays the identification information shown by the dotted line. (Identification device 20)

[0036] The identification device 20 decodes (decrypts) the code 11 contained in the identification label 10. The identification device 20 is capable of decrypting the information encrypted in the code 11 and can decrypt the information encrypted in the code 11 by executing a decryption program. The identification device 20 can run the decryption program by pre-downloading a dedicated app or software.

[0037] The identification device 20 can be conveniently used as, for example, a smartphone, tablet, mobile device, or mobile terminal. A stationary type is also perfectly acceptable. The identification device 20 has one or more touch panels, operation buttons, etc. on a display. The identification device 20 can be used as a general-purpose smartphone, etc., by installing a decryption program. It can also be a dedicated mobile device capable of decryption. The identification device 20 can be configured as a system that allows users to set and use a username, password, etc., to log in to their own account, and can address issues such as loss of the identification device 20 or unauthorized use by workers.

[0038] The identification device 20 includes a code reading unit that reads the code 11, a decoding unit that decodes the code 11, and a decryption unit that decrypts the information encrypted in the code 11. For example, an identification device 20 such as a smartphone has a camera function that photographs, scans, and reads the QR code 12 of the identification label 10 (code reading unit), and a QR code reader (decoding unit) that operates accordingly to encode and decode the QR code 12, etc. The identification device 20 has a browser for detecting the URL contained in the content of the QR code 12, etc., and for viewing a predetermined site, and has an application and scanner software for scanning and reading the code 11 of the QR code 12, etc. The scanner software scans the code 11 and converts it to "https: / / www.xxx.com / xxx / △△△", etc., to detect the URL, and the browser opens a predetermined site or page according to the URL. The URL is composed of a domain name portion that functions as the address of the site or page.

[0039] An identification device 20, which has the function of reading identification information data, reads the identification information of the battery pack 1 from the identification label 10 of the battery pack 1 that has been recovered due to disposal, malfunction, etc. The identification device 20 decodes and identifies the data read by the reading unit in the decoding unit. However, since the coded data of the identification label 10 is readable, the string representing the identification information can be encrypted as a string that is not understood as identification information and stored in code 11, and only after the encryption is decoded by the decryption unit can it be read as a string representing identification information. For example, the QR code 12 of the identification label 10 is decoded so that "http: / / <general site 32>?...&code=XXX" becomes readable. The part "http: / / <general site 32>?..." is URL information and can lead to a specified site or homepage. The part "code=XXX" is a string representing identification information, and is encrypted as a string that is not understood as identification information and included in code 11. The identification device 20 obtains identification information from the data of the identification label 10. However, since the obtained identification information is encrypted, the decryption unit uses a decryption key to decrypt it into a string of characters representing the identification information, such as "code=XXX", thereby obtaining and making the identification information readable.

[0040] The example above ("http: / / <general site 32>?...&code=XXX") clearly shows the string representing the identification information after decoding the code 11 of the identification label 10 for easier understanding. However, the code 11 of the identification label 10 can be made to be in a state where data related to the identification information, including the string representing the identification information, cannot be displayed, displayed, or recognized without decryption. Encrypted data can consist of characters, symbols, diagrams, bumps, etc. that cannot be read or reacted to by code readers that do not have decryption capabilities, and surface treatments that make it unreadable can be applied. In this case, a normal QR code reader that does not have decryption capabilities cannot display the string representing the identification information, and the existence of the string representing the identification information itself cannot be recognized, thus hiding and stealthily concealing data and information related to the identification information.

[0041] The identification device 20 has a decryption key used for decryption and can decrypt the encryption. The decryption key can be sent from the server 30 to the identification device 20 by a secure delivery method, for example, from the administrator of the identification information or information related to the battery pack. The decryption key is assigned when the decryption program is executed or installed, and is assigned to the identification device 20 before decryption, so that the decryption program can be executed and the encryption can be decrypted. The decryption key can be changed and updated periodically, with each decryption. The identification device 20 requests and sends / receives information and data related to the battery pack 1 from the server 30 and the database 31. When making a request, it refers to the information about the battery pack 1 stored in the database 31, so it needs identification information (identification ID) linked to the data of the battery pack 1, and the decrypted identification information is used as that identification ID.

[0042] The identification device 20 has a communication unit for sending and receiving data and establishing communication connections, and can refer to, acquire, and view information and data related to the battery pack 1 from the server 30 and database 31 based on the identification information of the battery pack 1. The battery pack identification system 100 in Figure 1 has a server 30 that provides information and data related to the battery pack 1, and a database 31 that stores and records information related to the battery pack 1. The server 30 has functions for sending and receiving, storing, and recording. The server 30 sends and receives information and data related to the battery pack 1, including identification information, to and from the identification device 20, and also transmits it to the database 31, etc., for storage and recording. The server 30 can use any configuration and structure that has the function of receiving identification information from the identification device 20 and the battery pack 1, and transmitting information and data related to the battery pack 1. The server 30 can be located within a corporation, for example, or it can be a cloud, cloud server, etc., and it can also have an analysis cloud, etc.

[0043] The identification device 20 and / or the battery pack 1 (the identification device 20, etc.) directly or indirectly transmit and receive information and data related to the battery pack 1 including identification information. The battery pack 1 can directly transmit and receive such information and data related to the battery pack 1 including identification information by including a communication unit for performing said transmission and reception. Data transmission and reception can be performed via Wi-Fi, 5G, or the like, and can also be performed by connecting to BLE (Bluetooth Low Energy with low power consumption) or the like. The identification device 20 is attached, inserted, coupled, or the like to a predetermined position and posture of the battery pack 1, or the identification device 20 is arranged in proximity to the battery pack 1, so that the communicable battery pack 1 and / or the identification device 20 can connect and transmit and receive data.

[0044] The identification device 20 can include a measurement unit that measures and grasps battery states such as SOC and SOH. The server 30 can include an analysis server that analyzes and verifies measurement results from the identification device 20. Furthermore, the server 30 can be configured to exchange information with the analysis server, and can be configured as an analysis cloud or the like that performs analysis on the cloud. Data on the analysis cloud can be transmitted and received by the identification device 20 or an analysis device different from the identification device 20, or the like. The server 30, the analysis server, the database 31, and the like can be arranged in an in-house location or the like where data protection and management are easy. The battery pack identification system 100 can accumulate information and data related to the battery pack 1 on the analysis cloud or in the database 31, and can remotely monitor the battery pack 1.

[0045] The analysis server analyzes the measurement results of the battery pack 1 to determine its condition, performance, and information. This analysis can be quantified and concretized, for example, to determine whether the battery pack 1 is reusable or recyclable, its recommended use, usable period, maintenance period, the characteristics of each battery cell constituting the battery pack 1, identification of specific battery cells with degraded or deteriorated characteristics, variations between battery cells, and whether or not specific battery cells need to be replaced. This information can then be reflected in future use.
