Technical Field

[0002] With the widespread use of mobile devices such as smartphones and tablets, power banks, as portable power devices, have become an indispensable tool in modern life. Existing power banks typically provide basic charging and discharging functions, capable of providing power to mobile devices. However, current power bank products on the market have significant shortcomings in intelligent management, security, and user experience.

[0003] The defects of the existing technology are mainly reflected in the following aspects:

[0004] Fixed charging mode: Most power banks only support a single charging mode and cannot dynamically adjust according to the type of connected device or the power status, resulting in low charging efficiency or damage to battery life. Lack of personalized optimization: Existing power banks cannot be intelligently managed according to user usage habits (such as charging time or frequency), making it difficult to balance charging efficiency and battery protection. Limited user interaction: Traditional power banks mostly display power levels through simple LED indicators.

[0102] comprehensively processing the capacity state data, electrical performance parameters, current distribution data, and temperature distribution data to generate a health status assessment report of the power bank, including remaining use time prediction, performance degradation trend analysis, and safety risk rating.

[0103] The beneficial effects of the above technical solution are that the temperature monitoring submodule can timely detect overheating conditions and prevent thermal runaway risks; the current monitoring ensures that the charging and discharging processes are within a safe range and avoids overcurrent hazards; and the comprehensive health assessment can early warn potential safety hazards and achieve risk prevention.

[0104] In another embodiment, the charging adjustment module includes:

[0105] an analysis submodule for real-time processing and analysis of the monitoring data to obtain analysis results;

[0106] a classification and labeling submodule for classifying and labeling the charging demand characteristics of the power bank based on the analysis results to generate device charging feature parameters;

[0107] a policy execution submodule configured to execute corresponding charging strategy selection and adjustment based on the device charging feature parameters.

[0108] The working principle of the above technical solution is that the analysis submodule performs real-time monitoring data collection and processing on the device connected to the power bank; wherein the monitoring data can be collected by various sensors such as current detectors, voltage detectors, and temperature sensors configured inside the power bank; the monitoring data includes multi-dimensional information such as current change curve, voltage fluctuation, temperature change trend, etc. during device charging; the real-time processing process mainly performs preprocessing operations such as filtering, normalization processing, and signal conversion on the collected raw data to ensure the accuracy of subsequent analysis; the analysis results include device type judgment, charging stage identification, battery health status evaluation, and abnormal state identification, etc.

[0109] The classification and labeling submodule classifies and labels the device charging demand characteristics according to the analysis results; wherein the classification and labeling process includes: extracting the key features in the analysis results and inputting them into a pre-established classification model, which is trained by a large amount of historical charging data; the classification and labeling dimensions include device type labeling (such as mobile phone, tablet, earphone, etc.), charging stage labeling (such as trickle charging stage, constant current charging stage, constant voltage charging stage, etc.), charging rate demand labeling (such as fast charging, standard charging, slow charging, etc.), battery health status labeling (such as healthy, aging, abnormal, etc.); the generated device charging feature parameters are a comprehensive parameter set containing multi-dimensional labeling information, which is used for subsequent charging strategy formulation.

[0110] The policy execution submodule executes corresponding charging strategy selection and adjustment based on the device charging feature parameters; wherein the charging strategy includes: output voltage adjustment strategy, output current limitation strategy, charging stage switching strategy, temperature control strategy, charging protection strategy, etc. combination of multiple strategies; the strategy selection process is to match the device charging feature parameters with the pre-set strategy library to select the most suitable strategy combination for the current charging device; the strategy execution process includes real-time regulation and control of the power bank output circuit, such as adjusting the size of the output voltage, limiting the upper limit of the output current, controlling the charging time, etc. to ensure the safety and efficiency of the charging process.

[0111] Although the charging adjustment can improve the charging efficiency and safety, frequent data processing and strategy adjustment can also consume the power of the power bank itself, and the intelligent management system of the power bank further includes:

[0112] Based on the device charging state and the remaining power of the power bank, the optimization frequency is dynamically adjusted;

[0113] According to the dynamic adjustment result of the optimization frequency, the running interval time of the analysis submodule is configured.

[0114] The beneficial effects of the above technical solution are: through comprehensive evaluation of the device charging status and the remaining power of the power bank, the system operating frequency is dynamically adjusted, that is, the charging strategy is optimized once every operating interval. The specific adjustment can be to use higher frequency monitoring in the early stage of device charging or when the status changes greatly, and to reduce the monitoring frequency during the stable charging status period, thereby reducing system energy consumption while ensuring the charging effect.

[0115] In another embodiment, the user interaction module includes:

[0116] The status data generation submodule is used to generate corresponding charging parameters according to the charging strategy, apply the charging parameters to the charging process of the power bank, and continuously monitor the operating status data of the power bank during the charging process;

[0117] The status processing submodule is used to process and analyze the operation status data, generate operation status information, and distribute the operation status information to the visual indication submodule and the remote management submodule;

[0118] The visual indication submodule is used to receive the operation status information and display the corresponding monitoring data status information;

[0119] The remote management submodule is used to receive operation status information, including:

[0120] Establish a wireless connection with a remote device, transmit operating status information to a user application on the remote device, receive control instructions from the user application, and pass the control instructions to the charging strategy control unit to adjust the charging strategy.

[0121] The working principle of the above technical solution is as follows: the strategy execution submodule analyzes the charging strategy provided by the charging strategy management unit and extracts key charging parameters such as current value, voltage value, and charging time. The charging parameter generation process includes a comprehensive calculation of factors such as battery capacity, charging power requirement, and ambient temperature in the charging strategy to determine the most appropriate charging current and voltage combination. The strategy execution submodule transmits the generated charging parameters to the charging control circuit of the power bank via a control signal to start the charging process. After the power bank starts working, the strategy execution submodule continuously collects operating status data such as the battery voltage, charging current, temperature sensor data, and charging time inside the power bank.

[0122] The state processing submodule receives the operating status data collected by the strategy execution submodule and performs filtering and numerical calibration on this data. The state processing submodule analyzes and calculates the operating status data using a preset algorithm model to determine whether the power bank's current operating status is normal, including battery health assessment, charging efficiency analysis, and safety status monitoring. The state processing submodule integrates the analysis results to generate operating status information, which includes the power bank's real-time operating parameters, fault warning information, charging progress, and other content. The generated operating status information is distributed simultaneously to the visual indication submodule and the remote management submodule via the internal communication bus.

[0123] The visual indication submodule receives the operating status information transmitted by the status processing submodule and controls the LED indicator light or display screen on the power bank's housing based on the information content. The visual indication submodule converts the digital data in the operating status information into visual signals that are easy for the user to understand. The visual indication submodule indicates the operating status of the power bank through different color indicator flashing patterns or icon changes on the display screen. When the power bank is operating normally, the display is solid green, the display is flashing blue during charging, and a red warning is displayed when an abnormality occurs. The display content includes monitoring data status information such as battery percentage, charging speed indication, and temperature status prompts.

[0124] The remote management submodule receives the operating status information provided by the status processing submodule and establishes a connection with the user's mobile phone or other remote device through the wireless communication module; the remote management submodule first starts the wireless connection protocol, searches and identifies the pre-paired remote device, and establishes a stable data transmission channel; the operating status information is encapsulated and processed and then transmitted to the user application running on the remote device via wireless signals; after receiving the status information, the user application displays the detailed operating parameters of the power bank on the interface; when the user sends control instructions through the application, the remote management submodule receives these instructions and decodes them, converting the control instructions into a command format that the system can recognize; the processed control instructions are passed to the charging strategy control unit to realize remote adjustment and optimization of the charging strategy.

[0125] The beneficial effects of this technical solution are as follows: when an abnormal condition is detected, such as excessive temperature or unstable current, the policy execution submodule immediately adjusts charging parameters or interrupts the charging process to ensure charging safety. After processing, the status processing submodule distributes this information to the visual indication submodule and the remote management submodule, enabling efficient information transmission and sharing. When an abnormal condition is detected, this submodule alerts the user through a specific flashing pattern or color change. The remote management submodule also dynamically adjusts communication power and frequency based on signal strength and data transmission requirements, optimizing energy consumption while ensuring communication quality.

[0126] In another embodiment, the classification labeling submodule includes:

[0127] The device identification unit is used to identify the model, capacity, and cell type of the connected power bank, and generate a basic feature identifier for the device based on historical charge and discharge data;

[0128] Bin evaluation unit for:

[0129] Evaluate the current power level of the power bank by grading it into low energy range, medium energy range, and high energy range;

[0130] Combining the health status index of the power bank with the current power range, the device charging characteristic parameters are generated as the basis for selecting the charging strategy.

[0131] The working principle of the above technical solution is as follows: the device identification unit identifies the model of the connected power bank by detecting the interface signal characteristics (model identification is completed by analyzing the power bank interface communication protocol, voltage response characteristics and power demand characteristics), thereby obtaining the basic parameter information of the power bank (basic parameter information includes: the nominal capacity, battery cell type and factory parameters of the power bank, and the battery cell type includes lithium-ion battery, lithium polymer battery and other types of batteries); the device identification unit collects and stores the historical charge and discharge data of the power bank, including the number of charge and discharge times, the duration of each charge and discharge, and the current change trend; through analysis and processing of historical data, the device identification unit generates a usage characteristic curve of the power bank, which reflects the power change characteristics of the power bank at different usage stages, forming a basic characteristic identification of the device;

[0132] The grading evaluation unit receives the basic characteristic identification of the device, and calculates the current power level in combination with the real-time monitored voltage value of the power bank. Among them, the power level is calculated using a nonlinear mapping algorithm, considering the influence of the cell type on the relationship between voltage and power, as well as the correction factor of temperature on power estimation. According to the calculated power level, the grading evaluation unit divides the current state of the power bank into three energy intervals: low energy interval, medium energy interval and high energy interval. Among them, the low energy interval corresponds to the critical state before the power is exhausted, and a protective charging strategy is adopted; the medium energy interval is the working interval for daily use, and a standard charging strategy is adopted; the high energy interval When the power bank is close to being fully charged, a deceleration charging strategy is implemented to protect the battery cells. The tiered evaluation unit also calculates the health status index of the power bank by analyzing historical charging and discharging data. This index reflects the aging degree and capacity attenuation of the battery cells. The health status index is calculated based on the comparison of charging and discharging efficiency, the trend of internal resistance change and the temperature response characteristics, and the final evaluation result is obtained through a weighted fusion algorithm. Finally, the tiered evaluation unit correlates the current power range with the health status index and generates the device charging characteristic parameters. The device charging characteristic parameters include: recommended charging current, maximum allowable charging power, charging cut-off conditions and temperature monitoring thresholds.

[0133] In addition, the strategy execution submodule receives the device charging characteristic parameters generated by the grading evaluation unit, and selects a suitable charging strategy based on the ambient temperature and the charging requirements set by the user; among them, the charging strategies include: trickle pre-charging strategy, constant current fast charging strategy, constant voltage supplement strategy and pulse maintenance strategy, etc.; the charging strategy execution unit achieves precise control of the charging process by adjusting the charging current, voltage and charging time in real time; at the same time, the charging strategy execution unit also monitors abnormal conditions during the charging process, such as abnormal temperature increase, excessive voltage fluctuation or charging time exceeding expectations, and activates the protection mechanism when necessary to ensure charging safety.

[0134] The beneficial effects of the above technical solution are: the device charging characteristic parameters serve as the core basis for the subsequent charging strategy selection, ensuring that the system can provide the optimal charging solution according to the actual situation of the power bank, extending the service life of the power bank while ensuring charging safety.

[0135] In another embodiment, the policy execution submodule includes:

[0136] A strategy selection unit is used to dynamically match the optimal charging strategy based on the device charging characteristic parameters. The charging strategy includes: using an accelerated charging mode for power banks in the low energy range, implementing a standard charging mode for power banks in the medium energy range, and implementing a trickle charging mode for power banks in the high energy range;

[0137] The behavior optimization unit is used to analyze users' historical borrowing and returning behavior patterns and site demand characteristics, predict the urgency of power bank turnover needs, and dynamically adjust the charging strategy while ensuring battery health.

[0138] The working principle of the above technical solution is: the strategy selection unit intelligently matches the charging strategy according to the current power status of the power bank. When the power bank is placed in the charging slot, the real-time power parameters of the power bank are obtained through the power detection module. The strategy selection unit classifies the power bank into different energy intervals based on the real-time power parameters. For power banks in the low energy range, the system will enable accelerated charging mode. In this mode, the charging controller will provide a charging current within a preset range (larger), so that the battery can quickly absorb electrical energy within a safe threshold, thereby shortening the time period for the power bank to go from low power to a usable state. The accelerated charging stage usually lasts until the battery capacity reaches a certain proportion, at which time the system will automatically switch to a more gentle charging mode.

[0139] When the power bank is determined to be in the medium energy range, the strategy selection unit applies the standard charging mode. This mode uses a medium-intensity charging current, ensuring charging efficiency while also extending battery life. Standard charging mode is the system's default setting and is suitable for charging needs in daily use scenarios.

[0140] For power banks in the high-energy range, the system will implement trickle charging mode. In this mode, the charge controller reduces the charging current to a lower level, gently replenishing the battery's last bit of power and preventing battery loss due to overcharging. Trickle charging is particularly suitable for batteries nearing full capacity, effectively preventing overheating and internal pressure buildup.

[0141] The behavior optimization unit continuously collects and stores user borrowing and returning behavior data, including borrowing time, usage duration, return location, and other information. The system also records fluctuations in power bank demand across different locations, such as the distribution patterns of peak and trough periods.

[0142] By performing pattern recognition and trend analysis on this historical data, the behavior optimization unit generates user behavior models and site demand models. These models predict the urgency of power bank turnover over a period of time. For example, the system predicts a power bank shortage at a pre-set site during lunchtime.

[0143] The beneficial effect of the above technical solution is that based on these prediction results, the behavior optimization unit will provide optimization suggestions to the strategy selection unit, dynamically adjusting the charging strategy. For example, if high demand is predicted, the system will temporarily apply accelerated charging mode to some power banks in the medium energy range to quickly replenish the number of available devices. However, such adjustments are always made under the premise of ensuring battery health, and the risk of overcharging is limited by built-in battery health monitoring parameters.

[0144] In another embodiment, the visual indication submodule includes:

[0145] A status indicator unit is used to convert the operating status information into an intuitive visual indication signal, and to convey the current operating status of the power bank in real time through a visual indicator;

[0146] The display interaction unit is used to present the corresponding monitoring data status information on the display screen, including energy capacity percentage, charging progress, current charging mode and estimated completion time.

[0147] The working principle of the above technical solution is as follows: the status indication unit receives operating status information, which includes real-time operating parameter information of the power bank's internal circuit. The signal processing chip built into the status indication unit parses the received operating status information and classifies and judges parameter values ​​such as voltage, current, and temperature according to preset threshold ranges. When the parameter value falls within the normal operating range, the processing chip outputs a low-level control signal to the green LED indicator. When the charging status is detected, the chip switches the output pulse signal to drive the orange indicator light to flash. If an abnormal status parameter is detected, the chip immediately outputs a high-level signal to illuminate the red warning light.

[0148] The display interaction unit converts the absolute value of the battery capacity into a percentage, and calculates the estimated completion time based on the current charging current and remaining capacity. The converted data is transmitted to the LCD display controller through the serial communication interface. The display interaction unit distributes the information to different areas of the screen according to the preset display layout.

[0149] The beneficial effects of the above technical solution are: the energy capacity percentage is displayed in the upper part of the screen in the form of a progress bar and numbers, the charging progress is displayed in the central area through a dynamic icon, the current charging mode is displayed in the lower left corner with a text logo, and the estimated completion time is presented in the form of a countdown in the lower right corner.

[0150] In another embodiment, Figure 3 As shown, a smart management method for power banks includes:

[0151] S1: Real-time monitoring of the energy capacity, electrical performance parameters and temperature status of the power bank during charging, generating monitoring data;

[0152] S2: Dynamically select the corresponding charging strategy based on monitoring data;

[0153] S3: Based on the charging strategy, it provides visual indication of the power bank's operating status and supports remote monitoring and management.

[0154] The working principle of the above technical solution is as follows: S1: Monitoring data includes energy capacity, electrical performance parameters and temperature status; energy capacity monitoring continuously tracks the remaining power and available capacity of the battery through the built-in energy evaluation circuit; electrical performance parameter monitoring mainly focuses on electrical indicators such as input and output voltage, current intensity and internal resistance change; temperature status monitoring uses temperature sensors distributed in key locations of the battery pack and circuit board to collect real-time temperature changes in various parts of the system;

[0155] S2: Charging strategy selection is based on a comprehensive analysis of monitoring data, including: automatic identification of connected device type by identifying interface electrical characteristics; selection of the appropriate charging mode based on the current battery charge level and temperature; use of fast charging mode, standard charging mode, or trickle charging mode for different device types and charge states; charging strategy execution includes: adjusting output voltage and current parameters to match device requirements; dynamically adjusting charging power based on battery temperature changes; and automatically reducing the charging rate or interrupting the charging process when an abnormal condition is detected. The system also records user charging habits and optimizes charging parameter configurations for commonly used devices, ensuring charging efficiency while extending battery life.

[0156] S3: The visual indication system includes: an LED indicator light showing the current power level, with different colors representing different power ranges; a charging status indicator light showing charging in progress, charging completed, or an abnormal state.

[0157] The beneficial effects of the above technical solution are: timely reminding users through display interface or push notification, and giving corresponding handling suggestions to ensure that users can deal with potential risks.

[0158] In another embodiment, a power bank includes:

[0159] Battery packs, used to store electrical energy;

[0160] A charging port, used to connect to a power source to charge the battery pack;

[0161] Discharge interface, used to connect the device to be charged to output electrical energy;

[0162] An intelligent management system is used to dynamically optimize the charging process by driving the charging adjustment module through real-time monitoring data.

[0163] The working principle of the above technical solution is: when it is needed to supplement the power bank with power, the user connects the power bank with an external power source through the charging interface. The charging interface, as an entrance of power, transmits the power provided by the external power source to the inside of the power bank. After the power enters the power bank through the charging interface, it directly flows to the battery pack.

[0164] In the process of the power entering the battery pack, the intelligent management system starts to work.

[0165] The beneficial effect of the above technical solution is: if the power input is unstable, the system will adjust the current size to protect the battery from damage. This dynamic adjustment makes the charging process more stable and prolongs the service life of the battery.

[0166] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application.
