Abstract
Description
Technical Field
[0001] This invention belongs to the field of battery formation technology, and particularly relates to a personalized formation management system control method, storage medium and electronic device. Background Technology
[0002] The process by which the positive and negative electrode active materials of a lithium-ion battery are activated through specific charging and discharging methods after electrolyte injection, thereby improving the battery's overall performance, including charge and discharge performance, self-discharge, and storage, is called formation.
[0003] Different battery specifications have different requirements for parameters such as charging and discharging current and capacity limits during formation. For example, excessive current can cause the battery to react too quickly, increase battery polarization, and reduce battery performance. Improper capacity limits can lead to overcharging and over-discharging, posing a fire or explosion hazard. Furthermore, batteries with different material systems also have different requirements for parameters such as charging and discharging current, capacity limits, and cutoff voltage during formation. Misinterpreting these requirements can pose significant safety risks.
[0004] Traditional formation processes first compile different formation process flows based on information such as battery material system and model, distinguished by process flow name. At the start of production, the battery type is first determined manually, and then the formation process flow is manually selected for formation. To avoid mixing processes, a new formation process flow is usually compiled in the formation cabinet before switching battery models, and the original formation process flow is deleted. This poses a risk of errors in the compilation of formation process flows and omissions in deleting old process flows. Furthermore, when producing batteries of multiple specifications, employees are prone to issuing the wrong process flow, which can lead to battery performance degradation or overcharging / discharging, causing safety hazards. Summary of the Invention
[0005] The purpose of this invention is to provide a personalized formation management system control method to solve the technical problems of existing formation processes requiring manual selection of formation processes, the risk of process misuse, the inability to simultaneously form multiple battery models, and the inability of existing formation processes to identify whether the selected process matches the battery model.
[0006] To achieve the above objectives, the specific technical solution of the personalized management system control method of the present invention is as follows:
[0007] A personalized management system control method, including
[0008] In the formation management system, the battery code is bound to the initialization process and initialization parameters respectively, and the formation process is automatically written and called according to the battery code.
[0009] Furthermore, the specific steps are as follows:
[0010] In the formation management system, first compile an initialization process template, select a field in the battery code for binding, then set the formation parameters, select another part of the fields in the battery code for binding, and complete the compilation of the formation process;
[0011] Compile the calling rules for the transformation process;
[0012] During battery formation, the battery barcode is first scanned and uploaded to the formation management system. The formation management system then selects the specified fields based on the battery barcode, calls the formation parameters, and automatically compiles the formation process to perform the formation.
[0013] Furthermore, the specific rules for invoking the transformation process include:
[0014] Call the initial template code to determine the template;
[0015] Call the initial parameter code to determine the initial parameters;
[0016] Call the remaining code for the newly added parameters to determine the final parameters.
[0017] Furthermore, the battery code in this method is 24 bits, divided into seven fields: manufacturer code, product type code, battery type code, battery specification code, traceability information code, production date code, and serial number. Part of the battery code is used to bind and initialize the process, and part of the code is used to bind and initialize the parameters.
[0018] Furthermore, this method compiles an initialization process template in the formation management system, sets different formation steps, and forms a complete formation process by calling different steps.
[0019] Furthermore, steps can be canceled or added depending on the actual process.
[0020] Furthermore, this method binds different initialization parameters to certain fields in the battery code. Different initialization parameters can be bound through different codes, or multiple initialization parameters can be bound through one code.
[0021] Furthermore, this method also selects certain fields of the battery code to bind some parameters, which are used to override the initial parameters and modify the formation process.
[0022] Another object of the present invention is to provide a storage medium on which a computer program is stored, which, when executed by a processor, implements the above-mentioned personalized management system control method.
[0023] Another object of the present invention is to provide an electronic device comprising:
[0024] Processor; and,
[0025] A memory for storing executable instructions of the processor; wherein the processor is configured to execute the aforementioned personalization management system control method by executing the executable instructions.
[0026] The personalized management system control method, storage medium, and electronic device of the present invention have the following advantages:
[0027] (1) The present invention can select specific fields of the code and bind them to the formation parameters. The formation process can be automatically compiled by calculating the parameters, which can realize the simultaneous formation of batteries of different material systems and specifications while ensuring their differentiation and realizing customized formation.
[0028] (2) The formation process of the present invention is automatically written and called according to the battery code, without the need for manual selection, which can avoid the harm of misuse of the process;
[0029] (3) This technology binds the battery code (national standard) to the formation process, which can prevent the issued process from being mismatched with the battery model, and the formation process can be traced through the battery code. Attached Figure Description

[0033] Figure 4 This is the initialization process template in this invention. Detailed Implementation
[0034] To better understand the purpose, structure, and function of this invention, the following detailed description of a personalized management system control method of this invention is provided in conjunction with the accompanying drawings.
[0035] This invention involves creating personalized formation processes within a formation management system based on different product types, material systems, battery specifications, and other battery models. The formation management system extracts relevant fields from the battery code and binds them to the formation process, and establishes process selection rules to automatically call the corresponding formation process based on the fields in the battery barcode.
[0036] During battery formation, the battery barcode is first scanned and uploaded to the formation management system. The system then automatically selects the corresponding formation process based on the specified fields on the barcode, and performs formation automatically or with a single click. This allows for customized formation of batteries of different types, material systems, and specifications.
[0037] In this embodiment, the present invention is mainly divided into two aspects: one is the compilation and binding of the transformation process, and the other is the compilation of the calling rules for the transformation process.
[0038] like Figure 1 As shown, the first step is to create a personalized workflow.
[0039] First, an initialization process template is developed, and the initialization process is bound to the manufacturer's code, which enables hybrid formation of batteries from different manufacturers.
[0040] Initialization process template as follows Figure 4 As shown, each step is set with different working modes and voltage and current limits. Step 1 is low-current charging, and the current is calculated by combining the parameters bound to the control plan code and product type code with the formula. The initial voltage can be determined by the material system. If it needs to be changed, it can be overridden by binding other codes. Steps 2 to 7 are charge and discharge cycles. The specific number of cycles can be bound according to the control plan version number. The initial parameters can be set by the battery type code, battery specification code, control plan version number, etc. If they need to be modified, some parameters can be overridden by binding other codes. Figure 4 The parameters for each step in each working mode are set as follows: x1: charging rate of the first step, x2: normal charging and discharging rate, x3: cutoff rate; V1: upper limit voltage for charging in the first step, V2: upper limit voltage for normal charging, V3: lower limit voltage for normal discharging, A0: initial rated capacity of the model, a: capacity step, b: number of step levels, Z: number of cycles for steps 2-7.
[0041] It should be noted that the selection fields of the formation template can also be adjusted according to the actual situation. For example, different formation templates can be set and bound to material-related coding fields for different material systems, different formation templates can be set and bound to specification-related coding fields for different battery specifications, and different formation templates can be set and bound to shape-related coding fields for different battery shapes, etc.
[0042] The initial template is not fixed. The working mode and related calculation formulas in the template can be adjusted according to the actual process. Steps can also be canceled or added during actual use.
[0043] Then configure the initial voltage parameters. For example, for the NCM / LTO material system, the following initial values can be set:
[0044] V1 = 2.1, V2 = 3.0, V3 = 1.0 (Initial charge and discharge cutoff voltages, in V)
[0045] This parameter is linked to the battery type code, and different initial charge and discharge cutoff voltages are set for different material systems.
[0046] Next, configure the initial multiplier and cycle number. For example, in the first version of the control plan, the code is 01, and the following initial values can be set:
[0047] x1 = 0.5, x2 = 2, x3 = 0.1 (initial charge / discharge rate)
[0048] Z = 2 (Initial number of iterations for steps 2-7)
[0049] Next, configure the initial current and capacity. For example, for a 35Ah battery model with the code A1, the following initial values can be set:
[0050] A0 = 30 (Initial model rated capacity, unit is Ah, and is bound to battery specification code A)
[0051] a = 5 (capacity increments, in Ah, tied to battery specification code A)
[0052] b = 1 (number of steps, determined by battery specification code 1)
[0053] It should be noted that the material system is not limited to the NCM / LTO system in the first embodiment; other material systems such as NCM / C, NCA / C, LFP / C, etc., are also applicable to this invention.
[0054] The parameters mentioned in the examples are for reference only and can be adjusted in actual use. For example, the voltage range can be adjusted according to the material system. The voltage range of NCM / LTO fluctuates between 1.0V and 3.0V, the voltage range of NCM / C fluctuates between 2.8V and 4.5V, and the voltage range of LFP / C fluctuates between 2.5V and 4.2V. The initial capacity and capacity steps can be adjusted according to the battery model and specifications. Alternatively, the capacity can be directly bound to the battery model without calculation.
[0055] The selection of formation parameters is not limited to the part described in the first embodiment. Different parameters can be bound by different codes, or multiple formation parameters can be bound by one code. For example, the material system code can be bound to information such as magnification and cycle number. Alternatively, a specific formation process can be directly bound by a specific code, and only the process is called.
[0056] Finally, additional binding codes can be added according to actual needs. For example, binding the work order number with some formation parameters can enable differentiated setting of formation parameters for different work orders. Special codes can also be bound with some formation parameters to enable setting formation parameters for batteries with process abnormalities.
[0057] The second step is to compile the calling rules for the transformation process:
[0058] As attached Figure 2 As shown, the battery code, which is bound to the initial template, is called first.
[0059] Then the encoding that binds the initial parameters is invoked.
[0060] Finally, the newly added parameters are called to overwrite the initial parameters, thus modifying the transformation process.
[0061] The formation process in this embodiment mainly consists of four steps, as shown in the attached diagram. Figure 3 As shown, the battery code is uploaded first. When the battery is fixed on the fixture in the formation cabinet, the battery barcode is scanned and uploaded to the formation management system. Then, the manufacturer code field is extracted according to the calling rules to retrieve the initial formation template. Next, the formation parameters are automatically compiled and improved based on the code field. Based on the extracted battery code field, the formation process bound to that character is automatically retrieved. The formation parameters are calculated, and then the formation is started automatically or manually.
[0062] This invention achieves differentiated programming and calling of the formation process through the differences in battery coding. The national traceability system stipulates that current power battery codes are uniformly 24 digits, consisting of seven parts: manufacturer code, product type code, battery type code, battery specification code, traceability information code, production date code, and serial number. While the battery coding rules are unified, they also possess differences. Therefore, by binding the battery code to the corresponding formation process parameters, differentiated formation can be achieved.
[0063] The present invention also provides a storage medium storing a computer program thereon, which, when executed by a processor, implements the above-mentioned personalized management system control method.
[0064] The present invention also proposes an electronic device, comprising:
[0065] Processor; and,
[0066] A memory for storing executable instructions of the processor; wherein the processor is configured to execute the aforementioned personalization management system control method by executing the executable instructions.
[0067] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of the present invention.
