Description

Technical Field

[0001] This invention relates to the field of mobile power technology, and in particular to a power bank system with a multi-system battery cell compatibility configuration. Background Technology

[0002] In today's era of ubiquitous mobile devices, power banks, as an important tool for replenishing mobile devices, are being used more and more frequently. However, existing power banks have many shortcomings in terms of safety, posing potential risks to users.

[0003] Most power banks on the market currently have relatively simple safety monitoring mechanisms, typically only providing basic overcharge and over-discharge protection. Their monitoring of key parameters such as current, voltage, and temperature during charging and discharging is not precise or comprehensive enough. For example, some power banks use low-precision detection elements for current detection, failing to promptly capture subtle abnormal changes in current. When an internal short circuit or other issues cause a sharp rise in current, the delayed detection prevents the protection mechanism from triggering quickly, potentially leading to overheating of the battery cell and increasing the risk of fire or explosion.

[0004] Regarding voltage monitoring, some power banks have voltage detection chips with limited accuracy, making it impossible to accurately determine whether the battery cell voltage is within a safe range. If the battery cell voltage is too high, it may damage the internal structure of the cell, shorten its lifespan, or even cause it to fail, posing a safety hazard. Furthermore, existing power banks also suffer from slow response times in temperature monitoring. They cannot take timely measures when the temperature first becomes abnormal, only activating protection when the temperature becomes excessively high. By this time, irreversible damage may have already been caused to the battery cell and other components of the power bank.

[0005] In terms of user interface, many power banks only have simple indicator lights to display basic information such as battery level. Users find it difficult to intuitively and comprehensively understand the power bank's working status, such as the current charging mode, battery type, and battery health. This information display method is neither clear nor comprehensive, requiring users to spend more time and effort to determine the power bank's status, making operation inconvenient. For example, when users want to switch charging modes, the lack of an intuitive interface may require complex button combinations, increasing the difficulty of operation and the possibility of errors.

[0006] In terms of remote monitoring and control, most existing power banks lack the ability to wirelessly connect to and remotely control mobile devices such as smartphones. When users are out and about, they cannot check the remaining battery level and charging status of the power bank in real time, and cannot promptly recharge their mobile devices, causing significant inconvenience. Furthermore, if the power bank malfunctions during use, such as a decline in battery health, users may not receive timely alerts and be unable to take prompt action, potentially leading to more serious problems.

[0007] To address this, we provide a power bank system with compatibility with multiple battery cell systems. Summary of the Invention

[0008] The purpose of this invention is to solve the problems in the prior art by proposing a power bank system with multi-system battery cell compatibility.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: A power bank system with multi-system battery cell compatibility includes: The battery cell compartment module is divided into multiple independent sub-compartments. Each sub-compartment can accommodate one type of battery cell. The size and fixing structure of the sub-compartments are adapted to various common battery cell systems, and the bottom of the sub-compartments is equipped with an intelligent heat dissipation system. The intelligent cell identification and management module, integrated on the main control circuit board, is used to identify the type of assembled cells and dynamically adjust charging and discharging parameters according to the characteristics of the cells. The dynamic energy allocation algorithm module dynamically allocates charging energy based on the real-time status of the battery cell and the needs of the user's equipment. The compatibility circuit module has a universal cell interface design that supports the voltage range of various cells, and is equipped with a voltage adaptive module and a current regulation module. The intelligent operation interface and communication module provide an intuitive interface to display the power bank's working status, and integrate the communication module to enable remote interaction with a mobile APP.

[0010] Preferably, the intelligent heat dissipation system employs a combination of liquid cooling and air cooling, adjusting the heat dissipation intensity in real time according to the cell temperature. The adjustment of the heat dissipation intensity is based on a comparison between the real-time cell temperature and a preset temperature threshold, calculated using the following formula: Assume the real-time temperature of the battery cell is The preset temperature threshold is The initial value of heat dissipation intensity is When the real-time temperature of the battery cell exceeds a preset temperature threshold, the heat dissipation intensity is increased, and the increased heat dissipation intensity... The calculation formula is: in, This is the heat dissipation intensity adjustment coefficient, whose value is preset based on the performance of the heat dissipation system and the characteristics of the battery cell. It is used to quantify the impact of excessive temperature on heat dissipation intensity. At that time, the heat dissipation intensity remains at its initial value. .

[0011] Preferably, the intelligent cell identification and management module employs impedance spectroscopy analysis technology to detect the voltage characteristics of the cell. Internal resistance These parameters are used to identify cell type and assess cell health status. The formula for assessing the health status of battery cells is: in, This is the rated voltage of the battery cell. This is the measured voltage. This is the maximum allowable internal resistance for this type of cell. To measure the internal resistance, and These are the weighting coefficients for voltage and internal resistance in the health status assessment, respectively. Its value is preset based on the degree of influence of voltage and internal resistance on the health status of the cell.

[0012] Preferably, the dynamic energy allocation algorithm module collects data such as the voltage, current, and temperature of the battery cells and the charging power demand of user devices in real time, and analyzes and processes this data using fuzzy control or neural network algorithms. Based on the analysis results, it dynamically adjusts the power bank's output power and energy allocation strategy. When user devices require fast charging, energy is preferentially allocated from battery cells in good health and with excellent charging and discharging performance. When the battery cell temperature is too high or close to full charge, the output power is appropriately reduced to avoid overcharging or overheating. At the same time, the balance between battery cells is considered to avoid overcharging and discharging of any particular cell, thus extending the battery cell's lifespan.

[0013] Preferably, the cell interface of the compatibility circuit module supports common voltage ranges for ternary lithium-ion cells (3.6V-4.2V), pure cobalt lithium-ion cells (3.7V-4.35V), and other lithium-ion cell systems. The voltage adaptive module automatically adjusts the charging and discharging voltage parameters based on the cell type information provided by the intelligent cell identification and management module to ensure the safety and efficiency of the charging process. The current regulation module adjusts the output current in real time based on the results of the dynamic energy distribution algorithm.

[0014] Preferably, the compatibility circuit module is further equipped with a high-precision current detection resistor, voltage detection chip, and power management chip to monitor the changes in current, voltage, and power during charging and discharging in real time, providing accurate data support for the intelligent cell identification and management module and the dynamic energy distribution algorithm.

[0015] Preferably, the intelligent operation interface adopts a high-definition touch screen to display the working status of the power bank in real time, including the remaining power, charging mode, cell type, and cell health status information; the communication module is a Bluetooth 5.0 or Wi-Fi 6 communication module, allowing users to remotely monitor the status of the power bank through a mobile APP, set the charging mode, query cell information, receive safety warnings, and receive charging completion reminders.

[0016] Preferably, the mobile app also provides charging suggestions, battery cell maintenance reminders, and power consumption statistics. Charging suggestions are generated based on battery cell type, remaining power, and user device needs. Battery cell maintenance reminders are generated based on the battery cell's health status and usage time. The power consumption statistics function records the number of times the power bank is charged, charging time, and discharge power data, providing users with power consumption habit analysis and optimization suggestions.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By integrating high-precision monitoring equipment into the compatibility circuit module, the system can monitor current, voltage, and temperature changes during charging and discharging in real time and accurately. Once abnormal parameters such as excessive current, excessive voltage, or excessive temperature are detected, the control system will immediately trigger protection mechanisms, such as cutting off the charging or discharging circuit, reducing output power, or activating the cooling system. This comprehensive safety monitoring and protection mechanism effectively prevents safety accidents such as fires and explosions caused by abnormal battery cells, greatly reducing the risks for users when using power banks and providing a safer and more reliable charging environment.

[0018] 2. Equipped with a high-definition touchscreen as the main operating interface, users can intuitively view the power bank's working status, including key information such as remaining battery power, charging mode, and battery cell type. They can easily switch charging modes and adjust output power through simple touch operations. Simultaneously, it integrates a Bluetooth / Wi-Fi communication module, enabling wireless connection between the power bank and a mobile app. Users can monitor the power bank's status in real time, receive alarm information, adjust charging parameters, or remotely control it anytime, anywhere via the mobile app. This intelligent operation method allows users to easily manage the power bank regardless of their location, greatly optimizing the user experience and making power bank use more convenient and efficient.

[0019] 3. The power bank synchronizes its operating status and data to the mobile app via its communication module, enabling real-time data updates and backups. This feature offers multiple advantages. Firstly, even if a user changes phones, they can quickly restore the power bank's data and settings through the app, eliminating the need for tedious reconfiguration and improving ease of use. Secondly, the data backup function ensures that important information during power bank use is not lost, such as charging history and battery health status. Even if the power bank malfunctions or is lost, users can obtain relevant data from the app, providing strong evidence for subsequent maintenance, replacement, or troubleshooting, effectively enhancing data security. Attached Figure Description

[0020] Figure 1 This is a schematic diagram of the overall system architecture of the present invention. Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Example, refer to Figure 1 A power bank system with multi-system battery cell compatibility includes the following key components: Cell compartment module: The cell compartment is carefully divided into multiple independent sub-compartments. The size and fixing structure of each sub-compartment have been optimized to adapt to a variety of common cell systems on the market, including but not limited to ternary system and pure cobalt system.

[0023] The bottom of the sub-compartment integrates an intelligent heat dissipation system that combines liquid cooling and air cooling technologies to ensure that the battery cells maintain a suitable temperature under different operating conditions.

[0024] Intelligent Cell Identification and Management Module: This module is integrated on the main control circuit board and uses advanced impedance spectroscopy analysis technology to accurately identify the type of assembled cell by detecting key parameters such as the cell's voltage characteristics and internal resistance.

[0025] At the same time, charging and discharging parameters are dynamically adjusted according to the characteristics of the battery cell to ensure the safety and efficiency of the charging process.

[0026] Dynamic energy distribution algorithm module: This unit collects data such as the voltage, current, temperature of the battery cell and the charging power demand of user equipment in real time, and performs in-depth analysis and processing using fuzzy control or neural network algorithms.

[0027] Based on the analysis results, the power bank's output power and energy distribution strategy are dynamically adjusted to meet the charging needs in different scenarios.

[0028] Compatibility circuit module: The cell interface adopts a universal design, supports the voltage range of various cells, and is equipped with a voltage adaptive module and a current regulation module.

[0029] The voltage adaptive module automatically adjusts the charging and discharging voltage parameters based on the cell type information provided by the intelligent cell identification and management module; the current regulation module adjusts the output current in real time based on the results of the dynamic energy distribution algorithm to ensure the stability and safety of the charging process.

[0030] Intelligent operating interface and communication module: Provides a high-definition touch screen as the operating interface, which displays the working status of the power bank in real time, including key information such as remaining power, charging mode, cell type, and cell health status.

[0031] Meanwhile, it integrates Bluetooth 5.0 or Wi-Fi 6 communication modules to enable remote interaction with a mobile app, allowing users to monitor and control the power bank's status anytime, anywhere.

[0032] The power bank system demonstrates exceptional compatibility and flexibility. Users can easily replace batteries of different types and capacities as needed, and the system automatically identifies and adjusts to the optimal charging parameters. Furthermore, through a high-definition touchscreen and a mobile app, users can monitor the power bank's operating status in real time, enabling remote control and significantly enhancing convenience and safety.

[0033] Furthermore, the intelligent heat dissipation system adopts a combination of liquid cooling and air cooling, and its working principle is to adjust the heat dissipation intensity in real time according to the temperature of the battery cell.

[0034] The specific implementation is as follows: Temperature sensors are installed at the bottom of each sub-compartment of the battery cell compartment to monitor the temperature changes of the battery cells in real time.

[0035] When the real-time temperature of the battery cell is lower than the preset temperature threshold, the heat dissipation system maintains its initial heat dissipation intensity, mainly through air cooling.

[0036] Once the real-time temperature of the battery cell exceeds the preset temperature threshold, the cooling system immediately activates the enhanced cooling mode. At this time, the liquid cooling system starts working, using circulating coolant to remove the heat generated by the battery cell; simultaneously, the air-cooled fan speeds up, increasing airflow and further accelerating heat dissipation.

[0037] The adjustment of heat dissipation intensity is based on the comparison between the real-time temperature of the battery cell and the preset temperature threshold.

[0038] The specific calculation formula is as follows: The heat dissipation intensity adjustment coefficient is preset based on the performance of the heat dissipation system and the characteristics of the battery cell, and is used to quantify the impact of excessive temperature on heat dissipation intensity.

[0039] When the battery cell operates continuously in a high-temperature environment, the heat dissipation system can respond quickly and adjust the heat dissipation intensity to effectively prevent the battery cell from overheating. For example, during continuous fast charging tests at an ambient temperature of 40℃, the battery cell temperature was stably controlled within a safe range (e.g., not exceeding 50℃), ensuring the long-term stable operation of the power bank.

[0040] Furthermore, the intelligent cell identification and management module employs impedance spectroscopy analysis technology to achieve accurate identification of cell types and assessment of their health status.

[0041] The specific implementation steps are as follows: Cell type identification: By detecting key parameters such as the voltage characteristics and internal resistance of the cell, and comparing them with a preset cell type database, the type of cell assembled can be determined.

[0042] Cell health status assessment: The health status of the cell is calculated using the cell health status assessment formula.

[0043] The formula is: Among them, the rated voltage and the maximum allowable internal resistance are inherent parameters of the battery cell; the measured voltage and measured internal resistance are obtained by impedance spectroscopy analysis; the voltage weighting coefficient and the internal resistance weighting coefficient are preset according to the degree of influence of voltage and internal resistance on the health status of the battery cell.

[0044] Dynamically adjust charging parameters: Based on the assessment results of cell type and health status, dynamically adjust charging and discharging parameters, such as charging current and charging cut-off voltage, to ensure the safety and efficiency of the charging process.

[0045] Among its features, impedance spectroscopy analysis technology enables the system to accurately identify the type of assembled battery cells and precisely assess their health status. For example, for a battery cell with a measured voltage close to its rated voltage and low internal resistance, the system will assess its health status as good and provide more optimized parameter settings during charging, thereby extending the cell's lifespan.

[0046] Furthermore, the dynamic energy distribution algorithm module is one of the core components of the power bank system. It dynamically adjusts the charging strategy by collecting and analyzing relevant data from the battery cells and user devices in real time.

[0047] The specific implementation is as follows: Data acquisition: Real-time acquisition of data such as battery cell voltage, current, temperature, and charging power demand of user devices.

[0048] These data are acquired through high-precision sensors and monitoring circuits and transmitted to the dynamic energy distribution algorithm module for processing.

[0049] Algorithm processing: Fuzzy control or neural network algorithms are used to perform in-depth analysis and processing of the collected data.

[0050] The algorithm considers various factors, such as the real-time status of the battery cells, the charging needs of user devices, and the balance between battery cells, in order to generate the optimal energy allocation strategy.

[0051] Dynamic adjustment: Based on the results of algorithm processing, the power bank's output power and energy distribution strategy are dynamically adjusted.

[0052] When user devices require fast charging, energy is preferentially allocated from cells in good health with excellent charge and discharge performance; when the cell temperature is too high or close to full charge, the output power is appropriately reduced to prevent overcharging or overheating; at the same time, the balance between cells is considered to avoid overcharging and discharging of a certain cell, which would affect its lifespan.

[0053] In actual charging, the dynamic energy allocation algorithm module demonstrated outstanding performance. For example, when a user's device is connected to a power bank and requests fast charging, the system automatically allocates more energy from the battery cells in optimal health to meet the fast charging demand. Simultaneously, if a battery cell is detected to be too hot or close to full charge, the system immediately reduces the output power of that cell to prevent safety incidents.

[0054] This dynamic adjustment strategy not only improves charging efficiency but also extends the lifespan of the battery cells.

[0055] Furthermore, the compatibility circuit module is one of the key components in a power bank system to achieve compatibility with multiple types of battery cells.

[0056] Its key design points are as follows: Cell interface design: The cell interface adopts a universal design, supporting the voltage range of various cells.

[0057] The specific supported range includes ternary lithium-ion battery cells with voltages of 3.6V-4.2V, pure cobalt lithium-ion battery cells with voltages of 3.7V-4.35V, and common voltage ranges for other battery cell systems.

[0058] Voltage adaptive module: This module automatically adjusts the charging and discharging voltage parameters based on the cell type information provided by the smart cell identification and management module.

[0059] For example, when it is detected that the battery is a pure cobalt system cell, the voltage adaptive module will automatically adjust the charging voltage to the range of 3.7V-4.35V to ensure the safety and efficiency of the charging process.

[0060] Current regulation module: This module adjusts the output current in real time based on the results of the dynamic energy distribution algorithm.

[0061] When a user device needs fast charging, the current regulation module increases the output current to meet the demand; when the battery cell temperature is too high or close to full charge, the current regulation module reduces the output current to prevent overcharging or overheating.

[0062] In practical applications, this compatibility circuit module has demonstrated exceptional flexibility and stability. Regardless of the type and voltage range of battery cells used by the user, the power bank system can automatically adjust to the appropriate voltage and current for charging via the voltage adaptive module and current regulation module. This design not only improves the power bank's compatibility but also ensures the safety and efficiency of the charging process.

[0063] Furthermore, to ensure the stability and safety of the power bank system, the compatibility circuit module also integrates high-precision monitoring equipment to monitor changes in various parameters during charging and discharging in real time. The specific implementation is as follows: High-precision current sensing resistors: High-precision current sensing resistors are connected in series in the charging and discharging circuits. These resistors have extremely low resistance values ​​and extremely high accuracy (such as an error range of ±0.1%) to monitor current changes in real time and accurately. The detected current data is converted into digital signals by a high-precision analog-to-digital converter (ADC) and transmitted to the smart cell identification and management module and the dynamic energy distribution algorithm module for processing and analysis.

[0064] Voltage detection chips: High-precision voltage detection chips are installed between the positive and negative terminals of the battery cell and at the output terminal of the power bank. These chips can monitor the voltage of the battery cell and the output voltage of the power bank in real time, ensuring that the voltage fluctuates within a safe range. The voltage detection chips also convert analog signals into digital signals through an ADC and transmit them to the control system for further processing.

[0065] Temperature sensors: Temperature sensors are placed inside the battery compartment and in key areas of the power bank (such as near the cooling system) to monitor temperature changes in real time. High-precision, fast-response temperature sensors are used to ensure timely detection of temperature anomalies. Temperature data is also transmitted to the control system to trigger enhanced cooling modes or adjust charging strategies.

[0066] Real-time monitoring and protection mechanism: The control system judges the status of the charging and discharging process in real time based on the received current, voltage, and temperature data. Once any abnormal parameters are detected (such as excessive current, excessive voltage, or excessive temperature), the control system will immediately trigger protection mechanisms, such as cutting off the charging or discharging circuit, reducing output power, or activating the cooling system, to prevent safety accidents.

[0067] In practical applications, this high-precision monitoring equipment, combined with a real-time protection mechanism, provides comprehensive safety assurance for the power bank system. For example, during a charging process, if a battery cell experiences a sharp increase in current due to an internal short circuit, the high-precision current detection resistor will immediately detect this anomaly and transmit the data to the control system. The control system quickly determines that the current exceeds the safety threshold and immediately cuts off the charging circuit for that battery cell, preventing potential fire or explosion risks. Simultaneously, the system will also issue an alarm to the user through a smart operating interface or mobile app, reminding the user to check the status of the power bank and the battery cells.

[0068] Furthermore, the intelligent user interface and communication module are key components in the power bank system for enhancing user experience and enabling remote monitoring. The specific implementation is as follows: High-definition touchscreen design: The power bank features a high-definition touchscreen as its main operating interface, boasting high screen resolution and sensitive touch response. The touchscreen displays the power bank's operating status, including remaining battery power, charging mode, battery cell type, battery cell health status, current output voltage and current, and other key information. Users can easily switch charging modes, adjust output power, or view detailed battery cell information via the touchscreen.

[0069] Bluetooth / Wi-Fi Communication Module: The power bank integrates a Bluetooth 5.0 or Wi-Fi 6 communication module, enabling wireless connection with a mobile app. Users simply need to download and install the corresponding app on their phones to establish a connection with the power bank via Bluetooth or Wi-Fi. After successful connection, users can view the power bank's working status in real time, receive alarm information, adjust charging parameters, or perform remote control on the app.

[0070] APP Functionality: The mobile APP boasts a wealth of features, including but not limited to real-time monitoring of the power bank's status, setting charging reminders, viewing charging history, adjusting charging modes (such as fast charging, slow charging, trickle charging, etc.), and receiving battery health status alerts. The APP also provides a user manual and online customer support to help users better use and maintain the power bank.

[0071] Data Synchronization and Backup: The power bank synchronizes its operating status and data to a mobile app via a communication module, enabling real-time data updates and backups. This allows users to restore previous data and settings even if they change phones or lose the power bank, improving both ease of use and data security.

[0072] Users can easily view and control the power bank's status via a high-definition touchscreen, or remotely monitor and control it via a mobile app. For example, when out and about, users can check the power bank's remaining battery level and charging status through the app, ensuring that their phones and other devices are always fully charged. Furthermore, if the power bank malfunctions or its battery health deteriorates, the app will immediately alert the user, prompting timely action. This intelligent operation not only enhances ease of use but also significantly improves the power bank's safety and reliability.

[0073] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
