Description

Technical Field

[0001] This invention relates to the field of lithium battery manufacturing technology, specifically to a method, system, and device for detecting the consistency of channel wiring in soft-pack formation equipment. Background Technology

[0002] In the lithium-ion battery manufacturing process, the formation process is used to activate and form the electrochemical system of the cell, and is one of the key steps that determines capacity consistency, internal resistance level, and safety performance. For production lines of pouch cells, formation typically uses multi-channel parallel / series formation equipment to achieve batch processing: each cell corresponds to an independent electrical channel, and the channel side needs to simultaneously complete energy input and output and multi-point voltage signal acquisition to support functions such as constant current and constant voltage control, process monitoring, and abnormal protection.

[0003] Existing formation equipment typically includes not only main power lines but also various types of wiring harnesses and terminal connections, such as battery terminal voltage sampling lines and tab connection point voltage sampling lines. Due to the large number of channels, dense wiring harnesses, and diverse interface types, problems such as incorrect wiring sequence, cross-channel serial connections, poor terminal contact, and reverse polarity can easily occur after equipment assembly at the factory, on-site installation, repair and repositioning, or process modifications. These problems are not easily identifiable visually but can lead to measurement deviations and misjudgments in control strategies during the formation process, further resulting in risks such as overcharging, over-discharging, and abnormal heating, affecting yield and safety margins.

[0004] Traditional methods for verifying the consistency and correctness of wiring rely heavily on manual checks using multimeters, continuity meters, and other tools, channel by channel. This involves measuring terminal voltage, continuity, and polarity point by point to determine wiring correctness. While this method is generally applicable, in multi-channel scenarios, it requires repeated plugging and unplugging and tracing line by line, resulting in long testing cycles and high labor intensity. Furthermore, the test results are highly dependent on personnel experience and on-site conditions, easily affected by fatigue, record-keeping oversights, and unstable measurement contacts, leading to misjudgments or missed detections. For more subtle fault types, such as when a sampling line logically shows voltage but the polarity or channel assignment is incorrect, simple continuity measurements often fail to provide a reliable conclusion quickly.

[0005] Furthermore, as formation equipment evolves towards higher channel counts and higher-density integration, the demand for rapid verification on the production floor is increasing. After equipment commissioning, line changes, and maintenance, electrical consistency verification of all channels must be completed before deployment in the formation process to avoid introducing wiring issues into the long-cycle formation process. Simultaneously, companies are demanding greater traceability and standardization of test results, expecting more uniform steps to output test records or reports, reducing discrepancies between different shifts and personnel. Relying solely on manual point-by-point measurements is insufficient to balance efficiency, coverage, and consistency, becoming a common bottleneck restricting the delivery and operation / maintenance efficiency of formation equipment.

[0006] Therefore, the industry needs a wiring sequence verification method for multi-channel formation equipment. This method should be able to quickly identify typical problems such as the on / off status of each channel, cross-channel misconnections, abnormal terminal contacts, and reverse polarity connections without significantly increasing the complexity of on-site operations, while minimizing reliance on manual experience. Simultaneously, this method should be adaptable to the interface types and testing cycle requirements of flexible packaging formation scenarios, facilitating repeated use in factory commissioning, on-site acceptance, and periodic inspections and maintenance, thereby improving the efficiency and reliability of pre-formation quality control. Summary of the Invention

[0007] The purpose of this invention is to provide a method, system, and device for detecting the consistency of wiring in flexible packaging equipment channels. Through automated and programmed constant voltage excitation and signal readback analysis, the basic wiring verification of all channels of the equipment can be completed quickly and reliably.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A method for detecting the consistency of channel wiring in a flexible packaging formation device, the method being applied to a multi-channel series formation device and executed under the detection state before the formation device enters the formation operation, includes the following steps:

[0010] By connecting the line sequence detection fixture with the probe assembly of the formation equipment, multiple dummy cells set in the line sequence detection fixture are respectively connected to each formation channel of the multi-channel series formation equipment. Each dummy cell has an independent built-in voltage regulator and does not rely on the formation equipment for power supply.

[0011] The switching component in the line sequence detection fixture is controlled so that the dummy cells are selected in a predetermined order, and at any given time only one dummy cell outputs a constant detection voltage lower than the formation operation voltage to its corresponding formation channel, while the other dummy cells are in an open circuit state.

[0012] With the main power supply of the formation equipment off and its voltage acquisition system in operation, the readback voltage of each formation channel is acquired.

[0013] Based on the amplitude distribution and polarity characteristics of the collected readback voltage, the consistency of the wiring status of each formation channel is determined.

[0014] In the above technical solution, each of the dummy cells has an independent programmable voltage regulator integrated inside, which is used to output the constant detection voltage to its corresponding transformation channel when it is selected, and to keep it in an open circuit state when it is not selected.

[0015] In the above technical solution, under the detection state, the main power supply of the formation equipment is turned off, while the voltage acquisition system of the formation equipment remains in working state to read back and acquire the constant detection voltage.

[0016] In the above technical solution, based on the amplitude distribution and polarity characteristics of the collected readback voltage, the consistency of the wiring status of each formation channel is determined, including:

[0017] When a dummy cell is selected and outputs the constant detection voltage, if the formation equipment fails to collect a voltage signal on the voltage sampling lines of all formation channels, or if the collected voltage signal is lower than the preset minimum effective voltage threshold, then it is determined that there is an open circuit in the corresponding formation channel.

[0018] When a fake cell outputs the constant detection voltage to its corresponding formation channel, if the readback voltage collected by the formation equipment in the formation channel is similar in amplitude and opposite in polarity to the constant detection voltage, it is determined that the power line of the formation channel is reversed.

[0019] When a dummy cell outputs the constant detection voltage to its corresponding formation channel, if the formation equipment collects a voltage signal that matches the amplitude of the constant detection voltage on other formation channels besides that formation channel, it is determined that there is a circuit misconnection between the formation channels.

[0020] In the above technical solution, when testing the voltage sampling line, the formation equipment performs a probe short-circuit operation on the target formation channel and measures the dynamic impedance of the channel. When the measured dynamic impedance characteristics are inconsistent with the preset normal impedance characteristics, it is determined that the voltage sampling line of the formation channel is reversed.

[0021] In the above technical solution, the dummy cells are selected sequentially according to the formation channel number. Before the readback voltage acquisition of the current formation channel is completed and the detection of the channel is ended, the output of the dummy cells in the next formation channel is not started.

[0022] In the above technical solution, the consistency determination of the wiring status applies to both the power line connection relationship and the voltage sampling line connection relationship of the formation channel.

[0023] In the above technical solution, the switching component consists of a relay and / or a power MOSFET disposed inside the dummy battery cell or the tooling, and is used to realize the electrical connection or disconnection between the dummy battery cell and the corresponding formation channel under the drive of the control unit.

[0024] This invention provides a system for detecting the consistency of channel wiring in flexible packaging forming equipment, comprising:

[0025] A line sequence testing fixture includes multiple dummy cells, a switching component, and a control unit. The number of dummy cells corresponds to the number of formation channels in the formation equipment. Each dummy cell has an independent built-in voltage regulator and does not rely on the formation equipment for power supply.

[0026] The switching component is connected to the dummy cell and is used to selectively connect a single dummy cell to the corresponding formation channel under the control of the control unit, and to make the dummy cells that are not selected open to the outside.

[0027] A multi-channel series formation device includes a probe assembly, a voltage acquisition system, and a main power supply. The probe assembly is connected to the line sequence detection fixture to establish an electrical connection between the dummy cell and each formation channel. The main power supply is turned off during the detection state. The voltage acquisition system is used to acquire the readback voltage of each formation channel during the detection state.

[0028] The host computer is communicatively connected to the line sequence detection fixture and the formation equipment. It is used to receive the readback voltage and, based on the amplitude distribution and polarity characteristics of the readback voltage, to determine the consistency of the wiring status of each formation channel.

[0029] This invention provides a channel wiring consistency detection device for flexible packaging equipment, comprising: a housing;

[0030] Multiple dummy cells are disposed inside the housing. The number of dummy cells corresponds to the number of formation channels in the soft-pack formation equipment. Each dummy cell has an independent built-in voltage regulator and can output a constant detection voltage without relying on the power supply of the formation equipment.

[0031] A switching component, connected to the plurality of dummy cells, is used to selectively connect a single dummy cell to the corresponding formation channel under the action of a control signal, and to make the dummy cells that are not selected open to the outside.

[0032] A control unit, connected to the switching component, is used to control the selection of the dummy cells in a predetermined sequence;

[0033] The conductive electrode assembly is located on the docking side of the housing and is used to dock with the probe assembly of the soft-pack formation equipment to establish an electrical connection between the dummy cell and each formation channel.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] This application provides a method, system, and apparatus for detecting the consistency of wiring in a soft-pack formation equipment channel. By introducing a dummy cell with independent voltage regulation output capability during the pre-formation testing state, and applying a constant detection voltage to only a single formation channel at any given time, the wiring status of each channel in the formation equipment forms a distinguishable readback characteristic at the electrical level. During the testing process, the main power supply of the formation equipment is turned off for readback sampling, avoiding the safety risks associated with the use of real batteries in the testing, and ensuring the consistency between the testing path and the actual formation conditions. This invention can quickly, comprehensively, and consistently identify wiring problems such as open circuits, incorrect channel connections, reversed positive and negative connections of power lines, and abnormal voltage sampling lines in multi-channel formation equipment without the need for real cells. It reduces the complexity and probability of misjudgment in manual testing, and improves the reliability and safety of wiring verification during the commissioning, maintenance, and pre-production testing of formation equipment.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] This embodiment provides a method for detecting the consistency of wiring in flexible packaging equipment channels. Through automated and programmed constant voltage excitation and signal readback analysis, it can quickly and reliably complete the basic wiring verification of all channels of the equipment.

[0043] like Figure 1-4As shown, this invention is applicable to the wiring verification stage of multi-channel series soft-pack formation equipment before entering the formation operation. The wiring sequence detection fixture is specifically embodied as an integrated device, including: a portable housing, multiple dummy cells, a high-precision programmable voltage regulator, a switching component, a control unit, and a communication interface. Each dummy cell integrates an independent programmable voltage regulator, which outputs a stable and controllable detection voltage during the detection process. The multi-channel intelligent switching component, driven by the control unit, enables selective access of the voltage regulator output between different dummy cells. The communication interface facilitates command interaction and data transmission between the fixture and the host computer or the main control system of the formation equipment.

[0044] With the main power supply of the formation equipment turned off and only its voltage acquisition system kept running, a constant detection voltage is applied to each formation channel sequentially through a line sequence detection fixture. Different wiring abnormalities exhibit fundamentally different readback voltage characteristics at the electrical level, allowing for a consistency determination of the power line connection relationship and the voltage sampling line connection relationship.

[0045] like Figure 1 As shown, the present invention includes the following steps:

[0046] Step S1: Connect the line sequence detection fixture to the probe assembly of the formation equipment, so that multiple dummy cells set in the line sequence detection fixture are respectively connected to each formation channel of the multi-channel series formation equipment, wherein each dummy cell has an independent built-in voltage regulator and does not rely on the formation equipment for power supply.

[0047] like Figure 2 , 3 As shown, the wiring sequence detection fixture physically connects to the probe assembly of the formation equipment via the conductive electrode assembly 11 located at the bottom of the dummy cell 1. The conductive electrode assembly corresponds one-to-one with the power output line and voltage sampling line of the formation channel. Without altering the original wiring structure, each dummy cell simultaneously connects to the power path and sampling circuit of the corresponding formation channel. Figure 4 As shown, each dummy cell 1 integrates an independent programmable voltage regulator, which outputs a constant detection voltage to its corresponding formation channel when selected, and remains open-circuit when not selected, without applying voltage to any formation channel. This structural design allows for the construction of a complete detection circuit without the need for a real cell. It establishes a stable, controllable electrical connection between the detection fixture and the formation equipment, consistent with actual formation conditions, avoiding uncertainties caused by manual wiring or temporary wiring, and eliminating safety risks that may arise from the involvement of a real cell in the detection process.

[0048] Step S2: Control the switching component in the line sequence detection fixture so that the dummy cells are selected in a predetermined order, and at any given time only one dummy cell outputs a constant detection voltage lower than the formation operation voltage to its corresponding formation channel, while the other dummy cells are in an open circuit state.

[0049] The switching components include relays and / or power MOSFETs installed inside dummy cells or tooling. The control terminal or host computer can drive the switching components according to a preset channel number sequence, allowing the output of the regulated power supply to be sequentially connected to different dummy cells. This ensures that at any given moment, only one specific voltage excitation source exists in the entire detection system. Simultaneously, the formation equipment receives a control command at the start of detection, shutting down its main power supply and keeping only the high-precision voltage acquisition system operational. During detection, the formation equipment no longer outputs energy, acting as a passive signal acquisition terminal to read back the voltage response on each channel. By shutting down the main power supply of the formation equipment while keeping its voltage acquisition system operational, the constant detection voltage is read back. This combination of single-channel constant voltage excitation and main power shutdown avoids signal superposition or interference caused by simultaneous excitation of multiple channels, ensuring that different wiring abnormalities form clear and distinguishable electrical characteristics in the readback voltage.

[0050] Step S3: With the main power supply of the formation equipment off and its voltage acquisition system in operation, acquire the readback voltage of each formation channel.

[0051] During voltage sampling line testing, the formation equipment performs a probe short-circuit operation on the target formation channel and measures the dynamic impedance of the channel. When the measured dynamic impedance characteristics are inconsistent with the preset normal impedance characteristics, it is determined that the voltage sampling line of the formation channel is reversed. After the routine constant voltage readback test is completed, the voltage sampling line reversal is an abnormal situation that is difficult to accurately identify through static voltage. The formation equipment further performs a probe short-circuit operation to cause a transient change in the electrical state of the corresponding channel. In this process, by measuring the dynamic impedance response of the channel, impedance characteristics that are significantly different from the normal wiring state can be obtained. Since each dummy cell is in an open circuit state when it is not selected, the change in dynamic impedance comes from the abnormal relationship between the sampling path and the probe connection, distinguishing the voltage sampling line reversal from other wiring abnormalities.

[0052] In this embodiment, dummy cells can be selected sequentially according to the formation channel number. Before the readback voltage acquisition of the current formation channel is completed and the detection of that channel ends, the output of the dummy cell for the next formation channel is not initiated, ensuring that the detection results of each channel do not interfere with each other. Based on constant voltage static detection, dynamic impedance is introduced to expand the detection capability and achieve reliable identification of hidden anomalies such as reversed sampling lines.

[0053] Step S4: Based on the amplitude distribution and polarity characteristics of the collected readback voltage, perform a consistency determination on the wiring status of each formation channel. This consistency determination considers both the power line connection relationship and the voltage sampling line connection relationship of the formation channel.

[0054] Specifically, the following situations may exist:

[0055] When a dummy cell is selected and outputs a constant detection voltage, if the formation equipment fails to collect a voltage signal on the voltage sampling lines of all formation channels, or if the collected voltage signal is lower than the preset minimum effective voltage threshold, then there is an open circuit abnormality in the corresponding formation channel.

[0056] When a dummy cell outputs a constant detection voltage to its corresponding formation channel, if the readback voltage collected by the formation equipment in the formation channel is similar in amplitude but opposite in polarity to the constant detection voltage, then the power lines of the formation channel are reversed.

[0057] When a dummy cell outputs a constant detection voltage to its corresponding formation channel, if the formation equipment collects a voltage signal that matches the amplitude of the constant detection voltage on other formation channels besides that formation channel, then there is a circuit misconnection between the formation channels.

[0058] When the readback voltage characteristics are consistent with the preset normal voltage characteristics and dynamic impedance characteristics, the wiring of the formation channel is determined to be normal.

[0059] In this embodiment, the judgment threshold is configured by the host computer in the test software and can be modified in combination with the equipment model, cable length and on-site debugging results. This application does not limit the threshold, so as to ensure the detection sensitivity while reducing the probability of false judgment.

[0060] The wiring sequence testing fixture applies a constant test voltage sequentially to each formation channel during testing. Combined with the existing voltage acquisition system of the formation equipment, it analyzes the readback signals to automatically verify the channel wiring status. Since the dummy cells inside the fixture each have independent and controllable voltage output capabilities, and only one dummy cell is allowed to output voltage at any given time, while the others remain open-circuited, a testing circuit consistent with actual formation conditions is constructed without connecting a real battery, thus verifying the channel wiring sequence and polarity connection relationships.

[0061] In this operating mode, different wiring anomalies exhibit fundamentally different readback characteristics at the electrical level. For example, when a channel is open-circuited, no effective readback voltage can be generated in any channel; when the positive and negative terminals of the power line are reversed, the polarity of the readback voltage changes in the opposite direction; when a channel is incorrectly connected, a significant voltage response will be detected on the non-target channel. By comprehensively utilizing the above-mentioned differences in characteristics, this implementation method can not only identify anomalies that can be detected by traditional static voltage detection, but also automatically distinguish wiring error types that are difficult to accurately determine by relying solely on single-point voltage measurement.

[0062] Furthermore, as a further improvement or alternative embodiment of the above implementation method, the line sequence detection fixture described in this embodiment can be designed as a modular structure to improve its applicability and scalability on different types of formation equipment.

[0063] In this embodiment, the internal functional modules of the wire sequence detection fixture are divided according to electrical functions, including at least a voltage regulator module, a switching component module, a control module, and a communication interface module. The voltage regulator module is used to provide a constant, programmable detection voltage, and the switching component module is used to selectively connect the detection voltage between different dummy cells under the drive of the control unit.

[0064] The voltage regulator module and switching component module adopt a modular installation method that is detachable or configurable. The electrical parameters and interface types can be replaced or configured according to the channel voltage level, sampling accuracy requirements, and number of channels of different formation equipment models. For example, when the test object is switched from a low-voltage formation equipment to a high-voltage formation equipment, the corresponding voltage regulator module and matching switching component module can be replaced without adjusting the structure or docking method of the entire test fixture, enabling rapid adaptation to different equipment models.

[0065] Furthermore, in this embodiment, the control module can be further integrated with a display and operation interface for local configuration and monitoring of the detection process. Through the display and operation interface, the operator can set or adjust detection conditions such as the detection channel sequence, detection voltage parameters, and judgment thresholds according to actual detection needs. At the same time, the control module stores the readback voltage data and judgment results collected during the detection process and supports querying and retrieving historical detection data by time, device number, or channel number.

[0066] Through the modular design and functional expansion described above, the line sequence testing fixture in this embodiment can not only adapt to the differences in electrical specifications of different types of formation equipment, but also meet the needs for flexibility and management in various application scenarios such as debugging, maintenance and on-site testing, further improving the versatility and maintainability of the testing system in actual engineering applications.

[0067] Furthermore, since the line sequence detection fixture directly connects to the probe assembly of the formation equipment through the conductive electrode assembly, there is no need to modify the original needle bed structure or channel wiring. It is compatible with different models and different numbers of channels of formation equipment, and is also suitable for application scenarios with limited internal operating space, a large number of channels and dense wiring. It avoids the problems of limited operating space, unstable contact and low detection efficiency faced by manual point-by-point detection using a multimeter.

[0068] The wiring sequence testing fixture can automatically and consistently verify the wiring of power lines and voltage sampling lines in multi-channel formation equipment without the need for actual battery cells. Compared with manual multimeter point-by-point testing or conventional voltage testing solutions, it utilizes electrical characteristics that are difficult to obtain through traditional testing methods, such as single-channel constant voltage excitation, voltage polarity reading, and dynamic impedance response. Open circuits, incorrect connections, reverse polarity connections, and reversed sampling lines exhibit clearly distinguishable response characteristics during the testing process, making it more suitable for field applications in formation equipment with limited needle bed space, numerous channels, and complex wiring.

The switching component is connected to the dummy cell and is used to selectively connect a single dummy cell to the corresponding formation channel under the control of the control unit, and to make the dummy cells that are not selected open to the outside. A multi-channel series formation device includes a probe assembly, a voltage acquisition system, and a main power supply. The probe assembly is connected to the line sequence detection fixture to establish an electrical connection between the dummy cell and each formation channel. The main power supply is turned off during the detection state. The voltage acquisition system is used to acquire the readback voltage of each formation channel during the detection state. The host computer is communicatively connected to the line sequence detection fixture and the formation equipment. It is used to receive the readback voltage and, based on the amplitude distribution and polarity characteristics of the readback voltage, to determine the consistency of the wiring status of each formation channel.

10. A device for detecting the consistency of channel wiring in a flexible packaging forming equipment, characterized in that, include: chassis; Multiple dummy cells are disposed inside the housing. The number of dummy cells corresponds to the number of formation channels in the soft-pack formation equipment. Each dummy cell has an independent built-in voltage regulator and can output a constant detection voltage without relying on the power supply of the formation equipment. A switching component, connected to the plurality of dummy cells, is used to selectively connect a single dummy cell to the corresponding formation channel under the action of a control signal, and to make the dummy cells that are not selected open to the outside. A control unit, connected to the switching component, is used to control the selection of the dummy cells in a predetermined sequence; The conductive electrode assembly is located on the docking side of the housing and is used to dock with the probe assembly of the soft-pack formation equipment to establish an electrical connection between the dummy cell and each formation channel.
