The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1~Figure 3 , which is the first embodiment of the present invention, and provides an intelligent charge and discharge management system based on a lithium battery protection board. The intelligent charge and discharge management system based on a lithium battery protection board includes the following modules:

[0033] Acquisition module, used to collect lithium battery operation data for preprocessing;

[0034] Specifically, collecting lithium battery operation data for preprocessing refers to monitoring and collecting multi-source battery data through a lithium battery protection board, including cleaning and filtering current and voltage data, battery temperature data, power data, charge and discharge cycle data, and time data, filling in missing values ​​and converting them into a unified format. After collecting and preprocessing the lithium battery operation data, the acquisition module transmits the data to the analysis module and the control module.

[0035] By cleaning, filtering and filling missing values, data quality can be effectively improved, providing more accurate and reliable support for subsequent analysis and decision-making, which is of great significance for optimizing charging and discharging strategies, predicting battery life and real-time monitoring of battery health status. By comprehensively analyzing the collected multi-source data, the real-time status and performance trend of lithium batteries can be more accurately judged, so as to formulate more reasonable charging and discharging strategies, which can not only improve the battery efficiency and energy output, but also effectively extend the battery life. Real-time monitoring and analysis of battery temperature data can timely discover potential safety problems such as overheating, and avoid safety accidents by adjusting the charging and discharging strategies or taking emergency measures. The processed data is transmitted to the analysis module and the control module, which can realize the intelligent adjustment and optimization of lithium battery management strategies. This data-based decision support system can dynamically adjust the management strategy according to the actual operation of the battery, and improve the flexibility and intelligence level of the entire system.

[0036] An analysis module, used to analyze and detect the status of the lithium battery based on the collected lithium battery operation data;

[0037] Specifically, analyzing and detecting the lithium battery status according to the collected lithium battery operation data refers to performing real-time detection and analysis on the lithium battery status through the pre-processed lithium battery operation data transmitted by the acquisition module:

[0038]

[0039] in It is the lithium battery status indicator. This indicator takes into account the multi-source data of lithium batteries for calculation. The value range is , where the closer to 1, the better the lithium battery condition. is the total number of lithium battery operation data, is the time of the i-th detection, For time The battery voltage, For time The battery current, is the temperature, To time The number of charge and discharge cycles of lithium batteries, is the decay function, is the decay coefficient, which is used to indicate the decay importance of data over time. , , as well as It is a model parameter used to adjust the weights of different operating data of the lithium battery and is obtained through optimization of historical data. The analysis module analyzes the lithium battery status and sends it to the evaluation module and the control module.

[0040] By analyzing the operating data of lithium batteries in real time and calculating status indicators, the health status and performance level of the battery can be evaluated more accurately. This enables the battery management system to formulate reasonable charging and discharging strategies based on the actual status of the battery, thereby optimizing the battery's use efficiency and extending its life. According to the changes in the lithium battery status indicators, the battery management system can dynamically adjust the charging and discharging strategies, such as speeding up the charging speed when the battery is in good condition, or slowing down the charging speed when the battery is in poor condition, to prevent damage to the battery due to excessive charging and discharging. By continuously monitoring the changes in the lithium battery status indicators, the trend of battery performance degradation can be discovered in time, thereby achieving early warning of potential failures, which helps to take preventive measures to avoid equipment downtime or safety accidents caused by battery failure. Real-time monitoring of key parameters such as battery temperature, voltage, and current, and comprehensive analysis of these data to evaluate the battery status can effectively prevent overcharging, over-discharging, overheating, etc. that may cause battery damage or even safety accidents. Through continuous monitoring and evaluation of the lithium battery status, the battery life can be more accurately predicted, thereby optimizing the battery maintenance and replacement plan, reducing operating costs and ensuring the continuous and reliable operation of the system.

[0041] An adjustment module is used to formulate a lithium battery charging and discharging strategy based on the analyzed lithium battery status and lithium battery operation data;

[0042] Specifically, formulating a lithium battery charge and discharge strategy based on the lithium battery status obtained by analysis in combination with the lithium battery operation data refers to formulating a lithium battery charge and discharge strategy based on the lithium battery status obtained by analysis by the analysis module in combination with the lithium battery operation data:

[0043]

[0044] in is the lithium battery charging and discharging strategy at time t, is the lithium battery status indicator at time t, is the duration since the last charge and discharge, is the current capacity of the lithium battery, a, b, c are adjustment parameters used to balance the influence of status index, time and current capacity, For time The lithium battery voltage, Located at time and time t, is the ideal voltage for lithium batteries, In order to adjust the parameters affected by voltage, the adjustment module formulates the lithium battery charging and discharging strategy and sends it to the evaluation module to simulate and implement the evaluation strategy effect.

[0045] By analyzing the lithium battery status indicators and operating data, the charging and discharging strategy is intelligently formulated. This method allows the system to dynamically adjust the charging and discharging process according to the actual status and needs of the battery, optimize energy utilization efficiency, extend battery life, and reduce the risk of overcharging or over-discharging. By precisely controlling the charging and discharging process, the system can reduce unnecessary losses of lithium batteries and avoid overcharging or deep discharge, thereby extending the battery life while maintaining its efficient energy output. The formulated charging and discharging strategy takes into account the health status and safe operating range of the lithium battery, which helps to prevent potential safety problems such as overcharging and overheating, and improves the safety of the entire system. By adjusting parameters to balance the status indicators, time, existing power and voltage effects, the system can flexibly adapt to different usage scenarios and needs, whether in high-load applications or in long-term standby, it can ensure the optimal performance of the battery.

[0046] An evaluation module, used to evaluate the effectiveness of lithium battery charging and discharging strategies and implement countermeasures;

[0047] Specifically, evaluating the effect of the lithium battery charging and discharging strategy means that the evaluation module simulates and implements the formulated lithium battery charging and discharging strategy through the lithium battery protection board to evaluate the effect of the strategy:

[0048]

[0049] in It is an evaluation index for the effect of lithium battery charging and discharging strategy. To evaluate the time period, is the energy efficiency ratio of the lithium battery at time t, is the lithium battery charging and discharging strategy at time t, Time period for evaluation The number of charge and discharge cycles of the lithium battery in is the discharge ratio of the i-th charge-discharge cycle, To adjust the parameters, used to balance the influence of the depth of discharge ratio, For battery health status, is the ideal value of battery health status, Parameters that affect the battery health status.

[0050] By evaluating the impact of different charging and discharging strategies on the energy efficiency ratio, the strategy can be optimized to improve the energy utilization efficiency of the battery, which is crucial to extending the battery life and improving the user experience. By monitoring the discharge ratio and battery health status, the evaluation module can help identify charging and discharging patterns that may cause excessive wear of the battery, and adjust the strategy to reduce such wear, thereby extending the battery life. Evaluating the effectiveness of the charging and discharging strategy helps to identify and avoid operating conditions that may cause sudden degradation or failure of battery performance, thereby improving the reliability and safety of the entire system. By collecting and analyzing battery operating data, the evaluation module provides a powerful data support platform for the battery management system, so that the adjustment and optimization of the charging and discharging strategy can be based on actual operating data, rather than just theoretical models or assumptions. Optimizing the charging and discharging strategy not only improves the energy efficiency and life of the battery, but also helps reduce the environmental impact caused by battery replacement and disposal.

[0051] Furthermore, implementing countermeasures means that the evaluation module compares the evaluation strategy effect with the preset evaluation index after simulating the implementation of the lithium battery charging and discharging strategy. Compare and judge the advantages and disadvantages of lithium battery charging and discharging strategies:

[0052] like > , it means that the lithium battery charging and discharging strategy formulated by the adjustment module has advantages over the existing lithium battery charging and discharging strategy, the evaluation module transmits the formulated lithium battery charging and discharging strategy and the evaluation result to the control module, and the control module implements the lithium battery charging and discharging strategy and monitors the lithium battery status in real time through the acquisition module and the analysis module;

[0053] like ≤ , it means that the lithium battery charging and discharging strategy formulated by the adjustment module has no advantage over the existing lithium battery charging and discharging strategy and needs to be re-formulated. The evaluation module transmits the re-formulation strategy command to the adjustment module to regenerate the lithium battery charging and discharging strategy, and after the generation, the evaluation module re-simulates and implements the evaluation strategy effect to judge the advantages and disadvantages of the strategy compared with the existing charging and discharging strategy until > The evaluation module transmits the process of iteratively generating the charging and discharging strategy and evaluating the effect of the strategy to the control module to form a record.

[0054] By evaluating the effect of the charge and discharge strategy in real time and comparing it with the preset evaluation indicators, the system can dynamically optimize the strategy to achieve the best battery performance. This method ensures that the battery can operate in the best state under different usage conditions. Intelligent strategy adjustment not only optimizes the immediate performance of the battery, but also takes into account the long-term impact. It helps to extend the battery life by reducing unnecessary charge and discharge cycles and avoiding situations such as over-discharge. By fine-tuning the charge and discharge strategy, the battery's energy efficiency ratio can be improved, that is, the battery's working efficiency under a given energy storage capacity, which is of great significance for energy conservation and reducing operating costs. The system can self-adjust based on real-time feedback and evaluation results, and enhances its adaptability to different operating environments and battery states. This adaptability is achieved through continuous learning and optimization, enabling the system to handle complex and changing usage scenarios. By feeding back the evaluation results and charge and discharge strategies to the control module, the system realizes intelligent monitoring and management of the battery state, which not only improves management efficiency, but also ensures the safety of the battery during use. The system collects and analyzes a large amount of data and adopts a data-based decision-making process. This method improves the accuracy and efficiency of decision-making and reduces uncertainty based on experience or intuition.

[0055] The control module is used to intelligently control the operation of all modules and centrally store and manage data. The control module is connected to the other modules through a data circuit.

[0056] Specifically, intelligently controlling the operation of all modules means that the control module is connected to the remaining modules through a data circuit, all modules are integrated and installed on a lithium battery protection board, the control module centrally controls the operation of all modules and adjusts the remaining modules for coordination, and a display is provided on the control module. When the control module receives data transmitted by the remaining modules, the data is displayed to the staff through the display and the staff is allowed to adjust the operation of the control module through the display.

[0057] Through the integration of intelligent control modules, the system can monitor the status and performance indicators of the battery in real time, such as voltage, current, temperature and charge and discharge cycles. This real-time monitoring helps to promptly discover and solve potential problems and avoid battery damage, thereby improving the safety of battery use and extending its life. By collecting and analyzing operating data from the battery, the control module can intelligently formulate and adjust the charge and discharge strategy, optimize battery performance and extend its service life. This data-based decision support system provides a strong scientific basis for battery management. The integrated display provides an intuitive user interface, allowing staff to easily monitor battery status, obtain key information in a timely manner, and adjust control strategies as needed. This interactive experience not only improves the efficiency of battery management, but also enhances the operability and flexibility of the system. By centrally controlling the operation of all modules and adjusting the remaining modules for coordination, the system can operate in an optimal manner, reduce energy loss, improve the energy utilization efficiency of the battery, and reduce maintenance costs.

[0058] Furthermore, centrally storing and managing data means that after the other modules transfer the data to the control module, the control module will classify and store the data in a database and set access rights and access passwords. Each access right and access password corresponds to and is unique. The database monitors and records the data access process throughout and detects the data involved in the access after the data access is completed. After the detection is completed, an access detection record is generated and stored synchronously.

[0059] By setting unique access rights and passwords for each user or system, the present invention ensures data security and effectively prevents unauthorized access and data leakage. The centralized storage management mechanism enables data from different modules to be effectively classified, stored and retrieved, greatly improving the speed and accuracy of data processing. The data stored in the database can be used for in-depth battery performance analysis, including life prediction, performance degradation analysis, etc. These analyses help optimize charging and discharging strategies and extend battery life. Through centralized storage and management of data, the battery management system can make more accurate and efficient decisions based on real-time data, thereby improving the intelligence level of the entire system. The data in the database can be used to monitor the operating status of the battery and detect potential faults and anomalies in a timely manner. This helps to take preventive measures in a timely manner to avoid the occurrence of battery failures. Access detection records provide reliable evidence for the compliance use and security of data, help meet the requirements of laws and regulations, and provide audit tracking capabilities when data security incidents occur.
