According to one embodiment, the high-end battery cell 100 can communicate with an external electronic device 2000 via the communication module 150.

[0060] Although Figure 2 The communication module 150 is shown to be included in the high-end battery cell 100, but this disclosure is not limited thereto; the communication module 150 may be included in each of the plurality of battery cells 110, 120, ..., 130. Details relating to the communication module 150 will be referenced. Figure 3 Please provide an explanation.

[0061] Reference Figure 3 The communication module 150 may include a communication integrated circuit (IC) 151 and a first memory 153. Furthermore, certain components may be excluded from the communication module 150, or other general-purpose components may be further included in the communication module 150.

[0062] According to one embodiment, the communication IC 151 can receive battery information from the communication circuit 310 of the battery management device 300. Here, the communication IC 151 can communicate with the communication circuit 310 of the battery management device 300 via wired or wireless means. According to one embodiment, the communication IC 151 can communicate with the electronic device 2000 (see...). Figure 1 ) or server 3000 (see Figure 1 The communication IC 151 can transmit and receive data. For example, the communication IC 151 can provide battery information stored in the first memory 153 of the communication module 150 to the electronic device 2000 (see...). Figure 1 ) or server 3000 (see Figure 1 ).

[0063] According to one embodiment, battery information may be information related to the state of the battery cell 100, including the communication module 150. For example, battery information may include at least one of state of charge (SOC), state of health (SOH), resistance, current cycle, predicted remaining cycle, and charge rate (C-rate).

[0064] According to one embodiment, the communication IC 151 can receive encrypted battery information from the battery management device 300. The encrypted battery information may be battery information with modified data size and / or data format.

[0065] According to one embodiment, the communication module 150 may include an NFC communication module. When the communication module 150 includes an NFC communication module, the communication IC 151 may include a radio frequency (RF) interface capable of radio frequency (RF) communication. Here, the communication IC 151 can transmit NFC signals to and receive NFC signals from another device (e.g., electronic device 2000) in a contactless manner. For example, the communication IC 151 can receive or transmit signals in the NFC frequency band via an NFC antenna (not shown). According to one embodiment, the NFC antenna may include conductive wiring capable of receiving signals in the 13 MHz to 110 MHz frequency band. According to one embodiment, the NFC antenna can transmit and receive NFC signals in the 13.56 MHz frequency band. The communication IC 151 can be implemented in various structures, and the structure of the communication IC 151 is not limited or constrained herein.

[0066] According to one embodiment, the first memory 153 may store data used by other components of the communication module 150 (e.g., communication IC 151). According to one embodiment, the first memory 153 may store battery identification information and / or battery information received from the battery management device 300. According to one embodiment, the first memory 153 may store encrypted battery identification information and / or encrypted battery information received from the battery management device 300.

[0067] According to one embodiment, battery identification information may include information for identifying battery cell 100, which includes the communication module 150. For example, battery identification information may include, but is not limited to, the product serial number of the high-end battery cell 100. Therefore, the battery management device 300, external electronic device 2000, or a user can identify the battery cell 100 associated with the communication module 150 using the battery identification information.

[0068] According to one embodiment, the communication module 150 can operate without a power source. According to another embodiment, when the communication module 150 is an NFC module, it can be configured as a power-free communication module without a power source. Therefore, in embodiments where the communication module 150 is an NFC module, the communication module 150 can transmit and receive data with an external device (e.g., electronic device 2000) using power generated by the NFC antenna during tag sensing.

[0069] On the other hand, the communication module 150 can operate independently of the high-order battery cell 100, the plurality of battery cells 110, 120, ..., 130, and / or the battery management device 300. According to one embodiment, the communication module 150 can operate independently of the operating state of the battery management device 300. For example, even when the battery management device 300 is not operating, the communication module 150 can communicate with external electronic devices. Therefore, even when the battery management device 300 is not operating, the communication module 150 can still send and receive data with external electronic devices. Moreover, since the communication module 150 can communicate with external electronic devices without using power from the high-order battery cell 100, the plurality of battery cells 110, 120, ..., 130, and / or the battery management device 300, no power loss of the battery pack 1000 is caused. Therefore, even when the battery management device 300 is turned off, the data stored in the first memory 153 of the communication module 150 can be sent to external devices, thereby preventing over-discharge due to current consumption by the battery management device 300.

[0070] According to one embodiment, the communication module 150 may include a wireless communication module (e.g., a cellular communication module, a short-range wireless communication module, or a Global Navigation Satellite System (GNSS) communication module) or a wired communication module (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). The wireless communication module and / or the wired communication module can communicate with external electronic devices via a short-range communication network or a long-range communication network. The short-range communication network may include Near Field Communication (NFC), Bluetooth, Wireless Fidelity (WiFi) Direct, or Infrared Data Association (IrDA). The long-range communication network may include traditional cellular networks, 5G networks, next-generation communication networks, the Internet, or computer networks (e.g., LANs or WANs). The wireless communication module and / or the wired communication module may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips).

For example, when electronic device 2000 includes a main processor and an auxiliary processor, the auxiliary processor may be adapted to consume less power than the main processor or dedicated to a specific function. The auxiliary processor may be implemented as separate from the main processor or as part of the main processor.

[0108] Figures 5 to 7 This is an illustration of a method of operating an electronic device according to an embodiment disclosed herein.

[0109] According to one embodiment, Figures 5 to 7 The operation of the electronic device 2000 shown can be controlled by Figure 4The processor 2040 executes. For ease of description, each of the higher-order battery cell 100 and / or multiple battery cells 110, 120, ..., 130 can be collectively referred to as battery cell 100.

[0110] Reference Figure 5 The operation method of the electronic device 2000 according to the embodiments disclosed herein may include step S510 performed by the electronic device 2000 to identify and / or authenticate a user, step S520 performed by the electronic device 2000 to receive battery identification information from battery cell 100, step S530 performed by the electronic device 2000 to request battery passport information from server 3000 based on user information and battery identification information, and step S540 performed by the electronic device 2000 to receive at least a portion of battery passport information from server 3000.

[0111] In step S510, the processor 2040 of the electronic device 2000 can identify and / or authenticate the user of the electronic device 2000. For example, the processor 2040 can identify whether the user of the electronic device 2000 is an authorized user, or authenticate whether the user of the electronic device 2000 is a user who has subscribed to the Battery Passport service. This user identification / authentication can be performed by an application used to use the Battery Passport service. For example, the processor 2040 can identify / authenticate the user by comparing the value input by the input / output module 2020 with a previously stored value. According to one embodiment, the processor 2040 can identify / authenticate the user of the electronic device 2000 by using subscriber information (e.g., International Mobile Subscriber Identity (IMSI)) stored in the application (or server 3000).

[0112] According to one embodiment, the processor 2040 can obtain user information through user identification / authentication. According to one embodiment, the user information can be stored in the electronic device 2000 or the server 3000. The user information can be information related to the identity of the user of the electronic device 2000. For example, the user information may include information such as user identification information, battery registration information, and / or access permission information. Alternatively, the user information may include information related to the identity of the user of the electronic device 2000 or unique identification information used to identify the user. For example, the user information may vary from user to user.

[0113] According to one embodiment, the processor 2040 of the electronic device 2000 can only receive data from the battery unit 100 when the user of the electronic device 2000 is an identified or authenticated user. In this way, the processor 2040 can ensure the security of the data sent to the electronic device 2000.

[0114] In step S520, the electronic device 2000 can receive battery identification information from the battery cell 100. For example, the battery identification information can be transmitted from the communication IC 151 of the battery cell 100 to the communication circuit 2010 and the processor 2040 of the electronic device 2000.

[0115] According to one embodiment, the processor 2040 of the electronic device 2000 can receive battery identification information stored in a first memory 153 of the communication module 150 of the battery cell 100. The battery identification information may include information capable of identifying the battery cell 100, including the communication module 150 (e.g., a serial number of the battery cell 100). References have been made to... Figure 3 Matters related to battery identification information have already been described, so they will not be repeated here.

[0116] According to one embodiment, battery identification information can be transmitted via NFC. For example, the battery identification information can be stored in the first memory 153 of the communication module 150 of the battery cell 100. When a user brings the electronic device 2000 close to the battery cell 100, the battery identification information can be transmitted from the battery cell 100 to the electronic device 2000. Therefore, the communication module 150 can communicate with the external electronic device 2000 independently of the operating state of the battery management device 300. In this way, even when the battery management device 300 is not working, the communication module 150 can send and receive various data, including battery identification information, from the electronic device 2000.

[0117] According to one embodiment, when the electronic device 2000 and the battery unit 100 are close to each other, an application for using the battery passport service can be automatically activated. Therefore, the electronic device 2000 can receive battery identification information through the application.

[0118] In step S530, the processor 2040 of the electronic device 2000 may request battery passport information from the server 3000 based on user information and battery identification information.

[0125] According to one embodiment, processor 2040 can request at least a portion of the battery passport information corresponding to the user's access permissions based on access permission information in the user information. For example, when the user information has public access permissions, processor 2040 can request publicly accessible battery passport information from server 3000. Processor 2040 can request battery passport information based on user information and battery identification information, thereby providing the user with selective access permissions to the battery passport information. Furthermore, when processor 2040 requests a portion of the battery passport information corresponding to the user's permissions, electronic device 2000 can receive a small amount of information from server 3000. In this way, electronic device 2000 can effectively receive the information required by the user.

[0126] According to one embodiment, when a user's access permissions are public, the processor 2040 can request publicly accessible information from the battery passport information from the server 3000. For example, the publicly accessible information in the battery passport information may include the information listed in Table 1 below.

[0127] [Table 1]

[0128]

[0129] Referring to Table 1, when the access permission is public, the processor 2040 can request at least one of the following information from the battery passport information that is related to the battery cell 100: manufacturing information, warranty information, composition information, material information, carbon footprint information, predicted lifespan information, recyclable material information, capacity information, voltage information, power information, temperature information, energy efficiency information, resistance information, charging rate information, cycle information, recycling information, EU declaration of conformity, waste battery prevention and management information, and renewable material content information.

[0130] According to one embodiment, when the user's access permissions are those of a legitimate rights holder or an executive committee, the processor 2040 can request information accessible to the legitimate rights holder or executive committee from the battery passport information from the server 3000. For example, the information accessible to the legitimate rights holder or executive committee in the battery passport information may include the information included in Tables 2 and 3.

[0131] [Table 2]

[0132] [Table 3]

[0133]

[0134] Referring to Tables 2 and 3, for example, when the access rights belong to a legitimate interest party or an executive committee, the processor 2040 may request information from the server 3000 related to at least one of the following in the battery passport information: composition information, parts replacement information, disassembly information, status information, safety measures information, performance information, durability information, SOH / SOC information, usage history information, recycled material information, capacity information, and renewable material content information.

[0135] According to one embodiment, when the user's access permissions are limited to a certification authority, market regulator, or executive committee, the processor 2040 can request information from the server 3000 that is accessible to the certification authority, market regulator, or executive committee within the battery passport information. For example, publicly accessible information in the battery passport information may include the information listed in Table 4 below.

[0136] [Table 4]

[0137] Referring to Table 4, for example, when the access permission is granted to a certification body, market regulator, or executive committee, the processor 2040 can request information related to legal compliance from the battery passport information from the server 3000. Information regarding legal compliance may include test reports used to check compliance with relevant battery passport regulations.

[0138] In step S540, the electronic device 2000 can receive battery passport information from the server 3000. According to one embodiment, the processor 2040 can receive battery passport information corresponding to the user's access permissions from the server 3000. The processor 2040 can receive at least a portion of the battery passport information corresponding to the user's access permissions, thereby reducing the amount of battery passport information and increasing transmission speed. The processor 2040 can also, based on the user's access permissions, receive only a portion of the battery passport information stored in the server 3000, rather than all of it, thereby improving the security of the battery passport information.

[0139] Reference Figure 6 The operation method of the electronic device 2000 according to the embodiments disclosed herein may include step S610 performed by the electronic device 2000 to identify and / or authenticate a user, step S620 performed by the electronic device 2000 to receive battery identification information and battery information from the battery cell 100, step S630 performed by the electronic device 2000 to send user information, battery identification information and battery information to the server 3000, step S640 performed by the server 3000 to store and / or manage battery passport information, step S650 performed by the electronic device 2000 to request battery passport information from the server 3000 based on user information and battery identification information, and step S660 performed by the electronic device 2000 to receive at least a portion of the battery passport information from the server 3000.

[0140] In operation S610, the processor 2040 of the electronic device 2000 can identify or authenticate the user of the electronic device 2000. This user identification / authentication can be performed by an application used to access the battery passport service. According to one embodiment, the processor 2040 can obtain user information through user identification / authentication. (See also...) Figure 5Descriptions regarding user identification / authentication and user information have been provided and will not be repeated hereafter.

[0141] In operation S620, electronic device 2000 can receive battery identification information and battery information from battery cell 100. For example, the battery identification information and battery information can be sent from the communication IC 151 of battery cell 100 to the communication circuit 2010 of electronic device 2000, and can be provided to the processor 2040 of electronic device 2000.

When the user brings the electronic device 2000 close to the battery cell 100, the battery identification information and battery information can be transmitted from the battery cell 100 to the electronic device 2000. Therefore, the communication module 150 can communicate with the external electronic device 2000 independently of the operating state of the battery management device 300. Thus, even when the battery management device 300 is not working, the communication module 150 can send and receive battery identification information and battery information from the electronic device 2000.

[0144] According to one embodiment, when the electronic device 2000 and the battery unit 100 are close to each other, an application for using the battery passport service can be automatically activated. Therefore, the electronic device 2000 can receive battery identification information and battery information through the application.

[0145] In operation S630, the processor 2040 of the electronic device 2000 can send user information, battery identification information, and battery information to the server 3000. According to one embodiment, the processor 2040 of the electronic device 2000 can send battery information to the server 3000, so that battery information about the battery cell 100 is managed as battery passport information for the battery cell 100.

[0146] According to one embodiment, the processor 2040 of the electronic device 2000 can send battery information received from the battery cell 100 to the server 3000, regardless of the user's access permissions. In this way, the processor 2040 can update the latest information about the battery cell 100 to the battery passport information, independent of the user of the electronic device 2000. Therefore, the processor 2040 can accurately manage the battery passport information.

[0147] In operation S640, server 3000 can store and / or manage battery passport information. For example, server 3000 can update the battery passport information based on provided user information, battery identification information, and battery information. According to one embodiment, server 3000 can store battery information in battery passport information corresponding to battery identification information. Server 3000 can categorize and store battery information by type. Therefore, server 3000 can manage battery information as battery passport information. In this way, server 3000 can keep the battery passport information up-to-date. Upon user request, server 3000 can provide battery passport information to the user. Therefore, the user can manage battery cell 100 using the latest battery passport information.

[0148] In operation S650, the processor 2040 of the electronic device 2000 can request battery passport information from the server 3000 based on user information and battery identification information.

The processor 2040 can receive at least a portion of the battery passport information corresponding to the user's access permissions, thereby reducing the amount of battery passport information and increasing transmission speed. The processor 2040 can also receive partial information different from the complete battery passport information stored in the server 3000, depending on the user's access permissions, thereby improving the security of the battery passport information.

[0150] refer to Figure 6The described operations S610 to S640 are also applicable to situations where the battery cell 100, electronic device 2000, or server 3000 are implemented by different manufacturers. For example, the server 3000 could be a high-level server 3000 that stores / manages battery passport information about battery cells 100 from different manufacturers. By managing the battery passport information in the high-level server 3000, users can easily manage battery cells 100 from various manufacturers.
