Terms such as “first,” “second,” or “first” or “second” may be used simply to distinguish a component from another corresponding component and do not limit the components in any other aspect (e.g., importance or order). Where any (e.g., 1st) component is referred to as “coupled,” “connected,” or “connected” to another (e.g., 2nd) component, with or without the terms “functionally” or “communicationly,” it means that said any component may be connected to said other component directly (e.g., via a wire), wirelessly, or through a third component.

[0027] Each component (e.g., module or program) of the components described in this document may include a singular or multiple entities. According to various embodiments, one or more of the components or operations may be omitted, or one or more other components or operations may be added. Generally or additionally, multiple components (e.g., module or program) may be integrated into a single component.

[0030]

[0031] FIG. 1 is a block diagram showing a system according to an embodiment of the present disclosure.

[0032] Referring to FIG. 1, the system (100) may include an electronic device (110), a data collection device (120), a status information transmission device (130), a scanning device (140), and a worker terminal (150).

[0033] The system (100) may be a system for classifying battery modules determined to be defective on a production line for producing battery modules. For example, the system (100) may determine whether a battery module is defective during an activation process in which the battery is activated and its safety is verified, and may provide location information of the battery module determined to be defective to a worker terminal (150) so that the battery module is classified. For example, the system (100) may detect a defect in a battery module during at least one of a charging / discharging process or an aging process in which the battery module is stored at a certain temperature and humidity for uniform dispersion of the electrolyte, and may classify the battery module from the normal battery module.

[0034] The electronic device (110) may refer to a server device for determining whether a battery module is defective and managing the classification of battery modules determined to be defective. The electronic device (110) can receive status information including identification information and measurement data of the battery module from the data collection device (120) and determine whether the battery module is defective. In this case, since the status information of the battery module is transmitted from the data collection device (120) at preset intervals, the electronic device (110) can determine that the battery module is defective at any point during the activation process.

[0035] The electronic device (110) transmits identification information of a battery module determined to be defective to a data collection device (120), so that the data collection device (120) can obtain identification information of a defective battery module being transported during the activation process in advance. When the data collection device (120) identifies that a battery module determined to be defective is undergoing a charging / discharging process or an aging process, the electronic device (110) can generate location information of the battery module determined to be defective and transmit it to a worker terminal (150).

[0036] Through this, a worker carrying a worker terminal (150) can identify the location information of a battery module determined to be defective, and can locate and classify the battery module in real time based on the location information.

[0037] The data collection device (120) may be a device such as a computer installed in a battery manufacturing plant, and may refer to a device for collecting and transmitting status information including identification information and measurement data of all battery modules being produced. The data collection device (120) may receive status information of the battery modules at preset intervals from a status information transmission device (130) mounted on each battery module and transmit it to an electronic device (110).

[0038] The data collection device (120) can receive and store identification information of a battery module determined to be defective by the electronic device (110). As described above, since the status information of the battery module is transmitted at preset intervals, i.e., in real time, the determination of defects in the battery module is also performed in real time during the activation process, and the data collection device (120) can obtain identification information of a battery module determined to be defective from the electronic device (110) at any point during the activation process.

[0039] The data collection device (120) can receive identification information of a battery module from the scanning device (140) whenever the identification code of a battery module being transported on a production line is scanned by the scanning device (140) located in correspondence with each process. The data collection device (120) can determine whether the identification information of the battery module received from the scanning device is identical to the identification information of a battery module determined to be defective, which was previously obtained from the electronic device (110). If identical, the data collection device (120) transmits the process information where the scanning device (140) is located, the identification information of the battery module, and the scanning order to the electronic device (110) so that location information of the battery module determined to be defective by the electronic device (110) can be generated.

[0040] A status information transmission device (130) may be a device mounted on a battery module for transmitting measurement data of each of a plurality of battery cells included in the battery module, along with identification information of the battery module, to a data collection device (120). For example, the status information transmission device (130) may be an IoT (Internet of Things) device and may include a wireless communication module that provides at least one of various wireless communication methods such as Bluetooth and LTE. The measurement data may include at least one of voltage data, current data, or temperature data of each of the plurality of battery cells.

[0041] The identification information of a battery module may be determined from the identification information of a predetermined battery cell among the identification information assigned to each of a plurality of battery cells. Alternatively, the identification information of a battery module may be assigned on a battery module basis, separately from the identification information assigned to each of the plurality of battery cells. The method for determining the identification information of a battery module is not limited to the examples described above, and any identification information capable of identifying a battery module is sufficient.

[0042] The status information transmission device (130) can obtain at least one of voltage data, current data, or temperature data measured for each of a plurality of battery cells by communicating with a device constituting a battery management system included in the battery module. Additionally, the status information transmission device (130) can obtain identification information of the battery module directly or indirectly at the time of mounting on the battery module. For example, identification information of the battery module may be input by an operator through the input interface of the status information transmission device (130). For example, identification information corresponding to the identification code may be provided to the status information transmission device (130) by scanning an identification code pre-equipped in the battery module by a scanning device (140) located at the time of mounting on the status information transmission device (130).

[0043] The scanning device (140) may be a device for obtaining identification information corresponding to an identification code by scanning the identification code of a battery module being transported along the production line, and positioned at each process of the production line. For example, the identification code may be a code using a black and white image such as a QR (quick response) code or a barcode. The identification code of the battery module may be provided on the outer surface of the battery module after a plurality of battery cells are assembled into a battery module.

[0044] The scanning device (140) can scan the identification code of the battery module in the order in which the battery module reaches the scanning location of the scanning device (140) and transmit the identification information of the battery module corresponding to the identification code to the data collection device (120). In this case, since identification information is also assigned to the scanning device (140) located in each process, the signal transmitted by the scanning device (140) to the data collection device (120) may include the identification information of the scanning device (140), the identification information of the battery module, and the transmission time information. The data collection device (120) can identify the process information where the scanning device is located based on the identification information of the scanning device (140). Additionally, the data collection device (120) can identify the scanning order of the battery module based on the identification information of the battery module and the transmission time information.

[0045] The worker terminal (150) may refer to a device carried by a worker performing sorting tasks so that battery modules determined to be defective can be removed from the production line before shipment. The worker terminal (150) may receive identification information and location information of battery modules determined to be defective from the electronic device (110). The location information may be generated based on the scan order of battery modules determined to be defective among all battery modules that entered one sub-process of the activation process (e.g., charge / discharge process or aging process, etc.) during a predetermined time interval.

[0046] For example, a battery module determined to be defective enters the aging process and may be scanned by the scanning device (140) as the fifth among all battery modules that have entered the aging process during a predetermined time interval. Since the location where the battery module is stored during the aging process is determined according to the transfer order, the transfer order may correspond to the scanning order. Accordingly, the electronic device (110) can identify where the battery module is stored in the storage area based on the scanning order of the battery module and can generate location information indicating the storage location. The worker terminal (150) can receive identification information of the battery module determined to be defective and location information indicating the storage location within the storage area from the electronic device (110). Through this, the worker can efficiently classify defective batteries by receiving accurate location information of the defective batteries without having to manually perform defect detection for each large number of battery modules being stored.

[0047] For example, a battery module determined to be defective may enter a charging / discharging process and be scanned by a scanning device (140) as the fifth among all battery modules that have entered the charging / discharging process during a predetermined time interval. Accordingly, the electronic device (110) can generate location information indicating the exact location of the battery module determined to be defective among the battery modules that have entered the charging / discharging process based on the scanning order of the battery modules. The operator terminal (150) can receive identification information of the battery module determined to be defective and location information in the area where the charging / discharging process is being performed from the electronic device (110). Through this, the operator receives the exact location information of the defective battery and performs classification, thereby allowing the battery module determined to be defective to be removed immediately upon confirming its location without waiting for it to unnecessarily go through a subsequent process.

[0048]

[0049] Hereinafter, with reference to FIG. 2, the configuration of the electronic device (110) and the operation in the process of determining whether the battery module is defective and classifying it will be explained in more detail.

[0050] FIG. 2 is a block diagram showing the configuration of an electronic device according to an embodiment of the present disclosure. The electronic device (200) shown in FIG. 2 may be an example of the configuration of the electronic device (110) of FIG. 1.

[0051] Referring to FIG. 2, an electronic device (200) according to an embodiment may include a transceiver (210), a memory (220), and a processor (230). At least one of the components included in the electronic device (200) may be omitted, or another component may be added to the electronic device (200). Additionally, some components may be implemented as an integrated unit or as a single or multiple unit. At least some components within the electronic device (200) may be implemented as an integrated unit or as a single or multiple unit. At least some components within the electronic device (200) may be connected to each other via a bus, GPIO (general purpose input / output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface), etc., to exchange data and / or signals.

[0052] The transceiver (210) can establish a wired or wireless communication channel with an external device (e.g., a data collection device (120) and a worker terminal (150)) and transmit and receive various data with the external device. To communicate with the external device via a wired connection, the transceiver (210) may include at least one port for connecting to the external device via a wired cable. The transceiver (210) may include a cellular communication module and be configured to connect to a cellular network (e.g., 3G, LTE, 5G, Wibro, or Wimax). According to one embodiment, the transceiver (210) may include a short-range communication module and transmit and receive data with the external device using short-range communication (e.g., Wi-Fi, Bluetooth, Bluetooth Low Energy (BLE), UWB), but is not limited thereto.

[0053] Memory (220) can store various data used by at least one component (e.g., processor (230)). Memory (220) can store instructions for the operation of the processor (230) described above. A program may be stored in memory (220) as software and may include, for example, an operating system, middleware, or an application. Unless otherwise specified, memory (220) in this disclosure may mean a set of one or more memories (220).

[0054] A processor (230) is configured to perform operations or data processing regarding the control and / or communication of each component of an electronic device (200) and may be operatively connected to the components of the electronic device (200). The processor (230) may load commands or data received from other components of the electronic device (200) into memory (220), process commands or data stored in memory (220), and store result data. Unless there are special circumstances, in this disclosure, a processor (230) may mean a set of one or more processors (230).

[0055] According to an embodiment, the processor (230) may receive status information including measurement data and identification information of the battery module from a data collection device (120) connected to the battery module. Here, being connected to the battery module means being connected via communication, and more specifically, it may mean that the data collection device (120) and the status information transmission device (130) mounted on the battery module are connected via communication.

[0056] According to an embodiment, the processor (230) can receive status information of the battery module from the data collection device (120) at preset intervals. For example, the preset interval may be a time interval during the activation process in which the status information of the battery module is transmitted multiple times during the charging / discharging process and the aging process. In this way, the processor (230) can receive real-time status information of the battery module while the activation process is being performed and determine in real-time whether there is a defect.

[0057] According to an embodiment, the status information of the battery module received by the processor (230) may be received via a data collection device (120) from a status information transmission device (130) mounted on the battery module. The status information transmission device (130) may be an IoT device and may include a wireless communication module that provides at least one of various wireless communication methods such as Bluetooth and LTE.

[0058] According to an embodiment, the processor (230) may receive measurement data from the data collection device (120) including at least one of voltage data, current data, or temperature data for each of a plurality of battery cells included in the battery module. In one example, the voltage data, current data, and temperature data for each battery cell may be configured as a single data subset, and the data subsets for each battery cell may be arranged in order based on the location of the battery cells in the battery module. The processor (230) may receive identification information of the battery module and status information composed of a plurality of data subsets arranged in this order.

[0059] According to an embodiment, the identification information of a battery module may be determined as the identification information of a predetermined battery cell among the identification information assigned to each of a plurality of battery cells. Alternatively, the identification information of a battery module may be assigned on a battery module basis separately from the identification information assigned to each of a plurality of battery cells. In this case, the identification information of the battery module may be in a combined form of the identification information of a plurality of battery cells. The identification information of the battery module may be an identifier composed of a string.

[0060] According to an embodiment, the processor (230) can determine whether the battery module is defective based on state information. The processor (230) identifies whether the state information of each of the plurality of battery cells included in the battery module is outside the normal range, and if the state information of one or more of the plurality of battery cells is outside the normal range, the processor (230) can determine that the battery module is defective. More specifically, the processor (230) receives measurement data of the battery cells included in the battery module and determines that the battery module is defective if there is one or more battery cells among the plurality of battery cells that are outside the normal range. That is, the processor (230) can determine that the battery module containing the battery cell is defective if one or more of the voltage data, current data, or temperature data of each battery cell has an abnormal value. The determination of defects in the battery cell performed in the present disclosure can be performed using a widely known method.

[0061] According to an embodiment, if the processor (230) determines that the battery module is defective, it can transmit identification information of the battery module to the data collection device (120). If the processor (230) determines that the battery module is defective at any point during the activation process, it provides the identification information of the battery module determined to be defective to the data collection device (120) in advance, thereby enabling the data collection device (120) to recognize the existence of the battery module determined to be defective when the battery module moves to enter a subsequent process.

[0062] According to an embodiment, the processor (230) may be configured to receive identification information of a battery module, process information where the scan device (140) is located, and the scan order of the battery module from the data collection device (120) when an identification code corresponding to identification information of a battery module determined to be defective is identified by a scan device (140) located in correspondence with each process.

[0063] According to an embodiment, the battery module may include a pre-equipped identification code. For example, the identification code may be a code using a black-and-white image, such as a QR code or a barcode. The identification code of the battery module may be provided on the outer surface of the battery module after a plurality of battery cells are assembled into the battery module. Since the identification code of the battery module corresponds to the identification information of the battery module, the identification information of the battery module can be obtained by scanning the identification code.

[0064] According to an embodiment, as the battery module reaches the scan position of the scan device (140), the identification code of the battery module is scanned by the scan device (140), and the identification information of the battery module corresponding to the identification code can be verified.

[0065] According to the embodiment, since identification information is assigned to the scan device (140) located in each process, the signal transmitted by the scan device (140) to the data collection device (120) may include identification information of the scan device (140), identification information of the battery module, and transmission time information. The data collection device (120) can identify the process information where the scan device is located based on the identification information of the scan device (140). For example, since the scan device (140) located in the charge / discharge process and the scan device (140) located in the aging process are assigned different identification information, the data collection device (120) that receives the signal transmitted by each scan device (140) can identify which process the signal was transmitted from. Additionally, the data collection device (120) can identify the scan order of the battery module based on the identification information of the battery module and transmission time information.

[0066] According to an embodiment, the processor (230) can receive identification information of a battery module transmitted from the data collection device (120) when the data collection device (120) confirms that the identification information of a battery module received from the scan device (140) is the same as the identification information of a battery module determined to be defective that was previously obtained from the processor (230).

[0067] In one example, when a data collection device (120) identifies that a battery module determined to be defective has entered the charging / discharging process based on an identification code scanned by a scanning device (140) located in the charging / discharging process, identification information of the battery module, process information indicating the charging / discharging process, and the scanning order of the battery module may be transmitted to a processor (230).

[0068] In one example, when a data collection device (120) identifies that a battery module determined to be defective has entered the aging process based on an identification code scanned by a scanning device (140) located in the aging process, identification information of the battery module, process information indicating the aging process, and the scan order of the battery module may be transmitted to a processor (230).

[0069] According to an embodiment, if the processor (230) determines that the battery module is defective, it may obtain location information of the battery module based on identification information of the battery module. More specifically, the processor (230) receives process information and a scan order corresponding to the identification information of the battery module from a data collection device (120), and may generate location information of the battery module based on the process information and the scan order. The location information may be generated based on process information of a sub-process (e.g., a charge / discharge process or an aging process, etc.) of an activation process into which the battery module determined to be defective entered during a predetermined time interval, and the scan order of the battery module determined to be defective among all battery modules that entered the said process.

[0070] In one example, when a battery module determined to be defective enters an aging process, the processor (230) can identify where the battery module is stored in a storage area based on process information indicating the aging process and the scan order of the battery module, and can generate location information indicating the storage location.

[0071] In one example, when a battery module determined to be defective enters a charging / discharging process, the processor (230) can identify where the battery module is located in the area where the charging / discharging process is performed based on process information indicating the charging / discharging process and the scan order of the battery module, and can generate location information indicating the location of the battery module within the area where the charging / discharging process is performed.

[0072] According to an embodiment, the processor (230) can transmit identification information and location information of a battery module to a worker terminal (150). The processor (230) can generate identification information and location information of the battery module as visual information and transmit it to the worker terminal (150). For example, the processor (230) can generate a storage area in the aging process or an area where the charging and discharging process is performed in the form of a map, and transmit visual information in the form in which identification information and location information of a battery module determined to be defective are displayed on the map to the worker terminal (150). Through this, the worker can easily identify the location of the battery module determined to be defective in each process and perform the sorting work efficiently.

[0073]

[0074] FIG. 3 is a flowchart illustrating a process for determining whether a battery module is defective and classifying the battery module according to an embodiment of the present disclosure.

[0075] Referring to FIG. 3, in step S301, the status information transmission device (130) can transmit status information of the battery module to the data collection device (120). The status information transmission device (130) is mounted on the battery module and can transmit measurement data of each of the plurality of battery cells included in the battery module, along with identification information of the battery module, to the data collection device (120) at preset intervals.

[0076] In step S303, the data collection device (120) can transmit status information of the battery module to the electronic device (110). The data collection device (120) can transmit status information received from the status information transmission device (130) to the electronic device (110). The measurement data included in the status information may include at least one of voltage data, current data, or temperature data for each of a plurality of battery cells.

[0077] In step S305, the electronic device (110) can determine whether the battery module is defective.

In this case, whenever the scanning device (140) scans the battery module, it can transmit a signal including identification information of the scanned battery module, identification information of the scanning device (140), and transmission time information.

[0082] In step S315, the data collection device (120) can identify that the battery module is determined to be defective. The data collection device (120) can compare the identification information of the battery module received from the scan device (140) with the identification information of the battery module determined to be defective, which was previously obtained from the electronic device (110), and identify that the two are identical.

[0083] In step S317, the data collection device (120) can transmit identification information of the battery module, the scan order of the battery module, and process information to the electronic device (110). The data collection device (120) can identify process information where the scan device is located based on the identification information of the scan device (140). Additionally, the data collection device (120) can identify the scan order of the battery module based on the identification information of the battery module and the transmission time information.

[0084] In step S319, the electronic device (110) can generate location information of the battery module. The electronic device (110) receives process information and a scan order corresponding to the identification information of the battery module from the data collection device (120), and can generate location information of the battery module based on the process information and the scan order. The location information can be generated based on process information of a sub-process (e.g., a charge / discharge process or an aging process, etc.) of an activation process into which a battery module determined to be defective during a predetermined time interval has entered, and the scan order of the battery module determined to be defective among all battery modules that have entered the said process.

[0085] In step S321, the electronic device (110) can transmit identification information and location information of the battery module to the worker terminal (150). The electronic device (110) can generate the identification information and location information of the battery module as visual information and transmit it to the worker terminal (150). The electronic device (110) can generate the area where the process is carried out in the form of a map and transmit visual information in the form where the identification information and location information of the battery module determined to be defective are displayed on the map to the worker terminal (150).

[0086] In step S323, the worker terminal (150) displays identification information and location information of the battery module on a display, thereby enabling the worker to perform the sorting of the battery module. The worker terminal (150) may display visual information on the display in the form of identification information and location information of the battery module determined to be defective being displayed on a map. Through this, the worker can easily identify the location of the battery module determined to be defective in each process and perform the sorting work efficiently.
