Description

[Technical Field]

[0001] The present invention claims the benefit of priority based on Korean Patent Application No. 10-2022-0102999, filed on August 17, 2022, and all contents disclosed in the documents of this Korean patent application are incorporated herein by reference.

[0002] SUMMARY OF THE INVENTION The embodiments disclosed herein relate to a battery manufacturing process control system and method of operation. [Background technology]

[0003] In recent years, research and development into secondary batteries has been actively conducted. Secondary batteries are batteries that can be charged and discharged, and include both conventional Ni / Cd batteries, Ni / MH batteries, and more recent lithium-ion batteries. Lithium-ion batteries, in particular, have the advantage of having a much higher energy density than conventional Ni / Cd batteries, Ni / MH batteries, and other batteries. Lithium-ion batteries can be manufactured to be small and lightweight, so they are widely used as power sources for mobile devices. In recent years, their range of use has expanded to include power sources for electric vehicles, and they are attracting attention as a next-generation energy storage medium.

[0004] Battery cells, the basic units that make up battery packs and / or modules, are composed of a positive electrode, a negative electrode, and a separator. Each battery cell is manufactured through processes such as electrode assembly, degassing, activation, charge / discharge, and aging. The performance and completeness of a battery cell can vary depending on process variables, such as the pressure applied to the battery cell by a pressure device, the internal temperature of the chamber, the charge / discharge conditions of the battery cell, and the length of time the battery is left unused. In the past, the setting of these process variables tended to rely heavily on the experience of engineers, making it difficult to predict the impact on the performance and completeness of battery cell products when replacing manufacturing equipment or changing the equipment settings or conditions.

[0034] FIG. 1 shows the configuration of a battery manufacturing process management system according to one embodiment.

[0035] Referring to FIG. 1, a battery manufacturing process management system according to one embodiment includes battery cell dummies (10, 11, 12, ...) for acquiring data related to the battery manufacturing process, and a controller 20 for controlling at least one process variable related to the battery manufacturing process based on the data acquired using the battery cell dummies.

[0036] The battery cell dummies (10, 11, 12, ...) are imitation products manufactured to the same specifications (size, standards, etc.) as actual battery cell products, and are input into the battery cell manufacturing process 30 and used to obtain data related to the manufacturing process.

[0037] A battery cell, as referred to in this specification, is a basic unit that constitutes a battery pack or a battery module. Each battery cell is manufactured through processes such as electrode assembly, degassing, activation, charge / discharge, and aging. Product performance and completeness can vary depending on process variables (e.g., pressure applied to the battery cell, internal temperature of the chamber, charge / discharge conditions, etc.). In the past, the setting of these process variables tended to rely heavily on the experience of engineers, making it difficult to predict the impact on the performance and completeness of battery cell products when replacing manufacturing equipment or changing equipment settings or conditions.

[0038] The dummy battery cells (10, 11, 12, ...) are put into a battery cell manufacturing process 30 and undergo the same processes as actual battery cells, and data relating to the battery manufacturing process, such as the pressure applied to the dummy battery cell, the internal or external temperature of the dummy battery cell, the amount of gas inside the dummy battery cell, and the degree of deformation of the dummy battery cell, is obtained, and the data is transmitted to the controller 20.

[0039] According to one embodiment, each of the dummy battery cells (10, 11, 12, ...) may include at least one sensor for acquiring the process-related data. For example, a pressure sensor for measuring the pressure applied to the dummy battery cell, a temperature sensor for detecting the internal or external temperature of the dummy battery cell, a gas amount sensor for measuring the internal gas amount of the dummy battery cell, a strain gauge for detecting deformation of the dummy battery cell, etc. may be built into or provided on the surface of the dummy battery cell.

[0040] FIG. 2a shows a side view of a battery cell dummy according to one embodiment.

[0041] As shown in the figure, the dummy battery cell 10 may have at least one pad-type sensor 110, 120, 130 built in. The sensors 110, 120, 130 may correspond to a pressure sensor, a temperature sensor, a gas amount sensor, etc. For example, the pressure sensor 110 may measure pressure applied to the dummy battery cell 10 from an external device during the manufacturing process or pressure applied from inside the dummy battery cell 10 due to expansion or deformation of the dummy battery cell 10, the temperature sensor 120 may measure the internal temperature of the dummy battery cell 10 or the temperature of the external environment, and the gas amount sensor 130 may detect the amount of gas generated inside the dummy battery cell 10.

[0042] FIG. 2b shows a plan view of a battery cell dummy according to one embodiment.

[0043] As shown, the battery cell dummy 10 may include at least one strain gauge 141-145 for detecting deformation of the battery cell dummy 10. According to one embodiment, the strain gauge is a device configured to detect minute mechanical changes as electrical signals, and may be a film-type sensor attached to the top surface of the battery cell dummy 10.

[0044] According to one embodiment, the sensors 110, 120, 130 and the strain gauges 141-145 can transmit measurement data to the controller 20 via a communication unit capable of wireless communication with an external device (such as Bluetooth (registered trademark), Wi-Fi (registered trademark), optical communication, or RF communication). Alternatively, a storage device included in the battery cell dummy 10 can compile data acquired by the sensors and transmit the measurement data to the controller 20 via the communication unit. Alternatively, the sensors and strain gauges can transmit the acquired data to an external device (such as a cloud PC) rather than the controller 20, and the controller 20 can acquire data related to the battery manufacturing process from the external device via a separate communication method.

[0045] The configuration and location of the battery cell dummy 10 and the sensors included therein shown in Figures 2a and 2b are exemplary only, and various sensors not specifically mentioned herein (e.g., image sensors, magnetic field sensors, current sensors, etc.) can be utilized to obtain data regarding the process.

[0046] 1, dummy battery cells (10, 11, 12, ...) are sequentially input into the battery cell manufacturing process 30, and data related to the battery manufacturing process (pressure, temperature, amount of gas, degree of deformation, etc.) is acquired from each of them. The data acquired using the multiple dummy battery cells can be stored in a process database after being labeled, and can be used to calculate optimal values ​​of process variables in the controller 20 and to control the process variables.

[0047] The controller 20 can control at least one process variable based on battery manufacturing process data acquired using the battery cell dummies (10, 11, 12, . . . ).

[0048] Process variables (or design variables) are variables that can be set by the battery manufacturer during the battery manufacturing process and can affect the performance, quality, etc. of the battery. For example, process variables can include the settings of the pressure device, the internal temperature of the chamber, the battery storage period / temperature, the battery charge / discharge conditions, etc. Such process variables affect the state of the manufactured battery cell. Specifically, the settings of the pressure device affect the pressure applied to the battery cell, the internal temperature of the chamber and the battery storage temperature affect the internal / external temperature of the battery, and the battery charge / discharge conditions (charging current / voltage, number of cycles, duration, etc.) can affect the amount of internal gas or temperature of the battery.

[0049] According to one embodiment, the controller 20 can optimize at least one process variable based on data acquired using dummy battery cells (10, 11, 12, ...). For example, the process environment (such as equipment settings, chamber temperature, and charge / discharge conditions) for manufacturing batteries with specific specifications can be optimized to produce batteries with desired performance and completeness. In this situation, if the process environment changes due to, for example, the introduction of new equipment, the installation of an additional line, or changes in external temperature / humidity, it has traditionally been difficult to obtain optimal results by applying the same process variables despite the change in environment, or by making some adjustments based on the experience of engineers.

[0050] In contrast, according to the battery manufacturing process management system of the embodiment, after a change in the process environment, dummy battery cells are introduced into the manufacturing process to obtain data, which is then compared with the previous process data to calculate and apply optimal process variables (i.e., settings for manufacturing a product similar to that before the environmental change), thereby obtaining process results similar to those before.

[0051] According to one embodiment, the controller 20 may transmit a warning message to a user based on a difference between data acquired using the dummy battery cells (10, 11, 12, ...) and pre-stored reference data. For example, if the pressure applied to the dummy battery cells exceeds an allowable pressure value, referring to the set value of a pressure device, a warning message ("Exceeding Allowable Pressure") may be output to the user in advance, thereby preventing potential damage during the manufacture of actual battery cells. As another example, the amount of gas, temperature, or degree of deformation inside the dummy battery cells may be compared with the allowable gas amount, temperature, or deformation value, respectively, and if the allowable values ​​are exceeded, a warning message may be output to the user in advance, thereby preventing potential damage during the manufacture of actual battery cells. Such warning messages may be output by a display device connected to the controller 20.

[0052] FIG. 3 shows a flowchart of a battery manufacturing process control method according to one embodiment.

[0053] 3, in step S310, data related to the battery manufacturing process can be acquired using a dummy battery cell. The dummy battery cell is a replica manufactured to the same specifications (size, size, etc.) as an actual battery cell product, and is used in the battery cell manufacturing process to acquire data related to the manufacturing process.

[0054] According to one embodiment, the data related to the battery manufacturing process may include at least one of the pressure applied to the dummy battery cell, the internal or external temperature of the dummy battery cell, the amount of gas inside the dummy battery cell, and the degree of deformation of the dummy battery cell.

[0055] FIG. 4 shows in detail the steps of acquiring data in a battery manufacturing process control method according to one embodiment.

[0056] 4, the step of acquiring data related to the battery manufacturing process (S310) may include the steps of measuring the pressure applied to the dummy battery cell (S311), detecting the internal or external temperature of the dummy battery cell (S312), measuring the amount of gas inside the dummy battery cell (S313), and detecting deformation of the dummy battery cell (S314). However, steps (S311 to S314) do not need to be performed simultaneously or sequentially, and only some of the steps may be performed, or the steps may be performed in an order different from that shown in the figure.

[0057] According to one embodiment, at least one of steps (S311 to S313) is performed by a pad-type sensor (e.g., pressure sensor 110, temperature sensor 120, gas amount sensor 130, etc. in FIG. 2a) built into the battery cell dummy, and step (S314) can be performed by a film-type sensor (e.g., strain gauges 141 to 145, etc. in FIG. 2b) attached to the surface of the battery cell dummy.

[0058] Referring again to FIG. 3 , in step S320, at least one process variable related to the battery manufacturing process can be controlled based on the manufacturing process data acquired using the dummy battery cell. The process variable is a variable that can be set by the battery manufacturer during the battery manufacturing process and can affect the performance, quality, etc. of the battery. For example, the process variable can include the settings of the pressure device, the internal temperature of the chamber, the battery storage period / temperature, the battery charge / discharge conditions, etc. Such process variables affect the state of the manufactured battery cell. Specifically, the settings of the pressure device affect the pressure applied to the battery cell, the internal temperature of the chamber and the battery storage temperature affect the internal / external temperature of the battery, and the battery charge / discharge conditions (charging current / voltage, number of cycles, duration, etc.) can affect the amount or temperature of internal gas in the battery.

[0059] According to one embodiment, the step of controlling at least one process variable (S320) may include a step of optimizing at least one process variable based on data acquired using a dummy battery cell. For example, when the process environment changes due to the introduction of new equipment, the installation of an additional line, changes in external temperature / humidity, etc., data is acquired by introducing a dummy battery cell into the manufacturing process, and the data is compared with the previous process data to calculate and apply optimal process variables (i.e., settings for manufacturing the same product as before the environmental change), thereby achieving the same process results as before.

[0060] FIG. 5 shows a flowchart of a battery manufacturing process control method according to another embodiment.

[0061] 5, in step S410, data related to the battery manufacturing process can be obtained using a dummy battery cell. Step S410 is similar to step S310 in FIG. 3, so a detailed description will be omitted.

[0062] In step S420, a warning message can be transmitted to the user based on the difference between the data acquired using the dummy battery cell and the pre-stored reference data. For example, if the pressure value applied to the dummy battery cell exceeds an allowable pressure value by referring to the setting value of a pressure device, a warning message ("exceeds allowable pressure") can be output to the user in advance, thereby preventing damage that may occur during the manufacture of actual battery cells. As another example, the amount of gas, temperature, or degree of deformation inside the dummy battery cell can be compared with the allowable gas amount, temperature, or deformation value, respectively, and if the allowable values ​​are exceeded, a warning message can be output to the user in advance, thereby preventing damage that may occur during the manufacture of actual battery cells.

[0063] The battery manufacturing process management method described above with reference to Figures 3 to 5 can be performed by the battery manufacturing process management system described above, but is not limited to this and can be performed by an apparatus or system having another configuration.

[0064] FIG. 6 illustrates a computing system that executes a battery manufacturing process management method according to one embodiment.

[0065] Referring to FIG. 6, a computing device 60 according to one embodiment disclosed herein may include an MCU 610, a memory 620, an input / output I / F 630, and a communication I / F 640.

[0066] The MCU 610 may be a processor that executes various programs stored in the memory 620 and performs the above-described antenna structure inspection method via such programs.

[0067] The memory 620 can store various programs related to battery diagnosis. Furthermore, a plurality of such memories 620 may be provided as needed. The memory 620 may be a volatile memory or a non-volatile memory. The memory 620 serving as a volatile memory may be a RAM, a DRAM, an SRAM, or the like. The memory 620 serving as a non-volatile memory may be a ROM, a PROM, an EAROM, an EPROM, an EEPROM, a flash memory, or the like. The examples of the memory 620 listed above are merely illustrative and are not limited to these examples.

[0068] The input / output I / F 630 can provide an interface that connects input devices (not shown) such as a keyboard, mouse, or touch panel, and output devices such as a display (not shown), to the MCU 610, enabling data to be sent and received.

[0069] The communication I / F 630 is configured to be able to transmit and receive various data to and from a server, and may be any device capable of supporting wired or wireless communication. For example, the communication I / F 630 can transmit and receive programs or various data for predicting the remaining life of the battery or for learning an artificial neural network from a separately provided external server.

[0070] The battery manufacturing process management method according to the above-described embodiment may be implemented as an application or in the form of program instructions executable by various computer components and recorded on a computer-readable recording medium. The computer-readable recording medium may include program instructions, data files, data structures, and the like, alone or in combination.

[0071] According to the embodiment of the battery manufacturing process management system and method described above, a dummy battery cell equipped with a sensor can be introduced into the battery manufacturing process in advance to obtain process-related data (e.g., pressure applied to the cell, temperature, amount of gas, degree of deformation, etc.), and a process database can be constructed based on the data. Furthermore, by calculating optimal process variables (e.g., pressure device settings, chamber temperature, charge / discharge conditions, etc.) in the battery manufacturing process and controlling the process variables, risks associated with equipment replacement or the installation of a new process line can be minimized. Furthermore, by providing feedback to the user based on the constructed database, battery cell performance degradation and defects caused by process variables can be prevented and improved.
