[0002] With the rapid development of new energy technologies and the rapid growth of the electric vehicle market, the demand for electric vehicle batteries has also increased significantly. As a core component of electric vehicles, the health of batteries is directly related to the performance, safety and user experience of the vehicle. In order to effectively manage the battery status, the charging and swapping cabinet system needs to have accurate battery health monitoring capabilities. However, the current battery health detection in the charging and swapping cabinet mainly relies on traditional methods in the battery management system (BMS).

[0003] Although these methods can provide information about the battery status to a certain extent, they have the following drawbacks:

BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Figure 1 This is a principle block diagram of an intelligent battery swap cabinet with battery health detection, display and interaction functions according to the present invention. DETAILED DESCRIPTION

[0048] The principles and features of the present invention are described below, and the examples are only used to explain the present invention and are not used to limit the scope of the present invention. The present invention is described more specifically by way of example in the following paragraphs. According to the following description and claims, the advantages and features of the present invention will become clearer.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0050] Example

[0051] See also Figure 1 As shown, a smart battery swap cabinet with battery health detection, display and interaction functions includes:

[0052] Battery health detection module: used to detect the health status of the battery in real time, record the battery power, voltage, temperature, SOH value parameters, and charge or disable the battery according to the detection results;

[0053] Display module: used to display the battery health status information, the operation status information of the battery swap cabinet and the battery charging status in real time. The displayed information includes the battery SOH value and health status;

[0054] Interactive function module: used for users to interact with the smart battery swap cabinet. The interactive content includes inputting the cabinet opening password, obtaining battery swap authorization and operation feedback. The interactive function module includes a touch screen, a button or a voice recognition system;

[0055] Backend server: responds to the user's request for power exchange when the smart power exchange cabinet is offline, generates a cabinet opening password by consulting a preset authorization list, and sends the password to the user's terminal device; the backend server is also responsible for verifying the password entered by the user, and guiding the smart power exchange cabinet to match the target power exchange cabinet module based on the verification result;

[0056] Data communication interface: used to connect the battery health detection module, display module, interactive function module and the background server for real-time data exchange.

[0057] The battery health detection module monitors the battery's power, voltage, temperature and SOH (State of Health) value in real time, and evaluates the battery's health status by comprehensively analyzing these parameters. This real-time detection can more accurately reflect the actual use of the battery, thereby effectively avoiding the accuracy problems and model complexity of traditional methods.

[0058] The display module provides high-resolution real-time display function, clearly presenting the battery health status information, the operating status of the battery swap cabinet and the battery charging status. By displaying the SOH value and health status, users can intuitively understand the actual status of the battery and make timely operational decisions.

[0059] The interactive function module includes a touch screen, buttons and voice recognition system, and users can easily enter the cabinet opening password, obtain battery replacement authorization, and get operation feedback. This diversified interactive method improves the convenience and experience of user operation, while increasing the security of the system.

[0060] The backend server can still respond to the user's request for battery replacement when the smart battery swap cabinet is offline. By referring to the preset authorization list to generate and send the cabinet opening password, the backend server can process the battery replacement request in the offline state and verify it according to the password entered by the user, thereby ensuring the security of the system and the smoothness of operation.

[0061] The data communication interface connects the battery health detection module, display module, and interactive function module to the backend server to achieve real-time data exchange. This real-time data synchronization function ensures the consistency of information between modules and improves the stability and reliability of the system.

[0062] The battery health detection and management method of the battery health detection module is as follows:

[0063] Use sensors and measuring devices to monitor the battery's charge, voltage, temperature and SOH value in real time;

[0064] The collected data includes the battery's remaining charge percentage, the battery's instantaneous voltage value, the battery's operating temperature, and the battery's health status percentage;

[0065] Recording the collected battery parameters in a data storage module;

[0066] Determine whether the battery is in sufficient power range, detect whether the battery voltage is within the safe range, monitor whether the battery temperature is too high, and determine the overall health status of the battery based on the SOH value;

[0067] A comprehensive health score is formed based on the above indicators; a charging operation is initiated, and the battery is disabled and marked as requiring recycling or disposal.

[0068] The battery power, voltage, temperature and SOH value are monitored in real time through sensors and measuring equipment to ensure that the actual status of the battery can be obtained in time; the battery charge percentage, instantaneous voltage, battery temperature and health status percentage are collected to provide detailed battery status information, which helps to accurately evaluate battery performance.

[0069] The data is recorded in the data storage module to support subsequent data analysis and tracking, making it easy to observe the health trend of the battery over a long period of time. The safety of battery use is enhanced by judging whether the battery is in a sufficient power range, whether the voltage is safe, and whether the temperature is too high.

[0070] The comprehensive health score formed based on various indicators provides an intuitive battery health assessment for quick decision-making. It can automatically start charging operations, disable unqualified batteries, and mark batteries that need to be recycled or disposed of, improving management efficiency and resource utilization. Through real-time monitoring and automatic management, it reduces the risk of battery failure, extends battery life, and ensures the normal operation of equipment.

[0071] The method to judge the health of the battery voltage is:

[0072] Voltage_Health=\frac{V_{current}-V_{min}}{V_{max}-V_{min}};

[0073] Where V_{current} = the current voltage of the battery, V_{min} and V_{max} are the minimum and maximum safe voltage values ​​of the battery.

[0074] The method to monitor whether the battery temperature is too high is:

[0075] Temperature_Health=1-\frac{|T_{current}-T_{optimal}|}{T_{range}};

[0076] Among them, T_{current} is the current temperature, T_{optimal} is the optimal operating temperature, and T_{range} is the allowable temperature range.

[0077] The method for forming a comprehensive health score is:

[0078] Overall_Health=w1\cdotVoltage_Health+w2\cdotSOC_Health+w3\cdotTemperature_Health+w4\cdotSOH_Health;

[0079] Among them, w1, w2, w3 and w4 are the weight coefficients of each indicator, which are manually set to a coefficient value range of 0.2-0.3.

[0080] Assume that the current battery data is as follows:

[0081] State of charge (SOC): 80%;

[0082] Voltage: 3.6V;

[0083] Temperature: 30℃;

[0084] SOH: 90%;

[0085] Calculate each health score and combine them to get the final battery health score:

[0086] Voltage_Health=\frac{3.6-3.0}{4.2-3.0}=0.75Temperature_Health=1-\frac{|30-25|}{20}=0.75SOH_Health=0.90;

[0087] Overall_Health=0.25\cdot 0.75+0.25\cdot 0.80+0.25\cdot 0.75+0.25\cdot 0.90=0.80;

[0088] In summary, the overall battery health score is 0.80, indicating that the battery is in good health.

[0089] By integrating four indicators, namely voltage, temperature, SOC (state of charge) and SOH (state of health), a comprehensive battery health assessment is provided, avoiding the misleading effect of a single indicator. The calculation formulas for voltage health and temperature health are based on actual measurement values, which can accurately reflect the true state of the battery and help to detect potential problems in a timely manner.

[0090] By adjusting the weight coefficients (w1, w2, w3, w4), the comprehensive health score can be optimized according to the actual application requirements and battery characteristics, so that the evaluation results are more in line with the requirements of specific applications; accurate health evaluation can promptly detect abnormal battery voltage or excessive temperature problems, so as to take corresponding measures (such as charging, disabling, etc.) to improve the safety and stability of the system; the comprehensive scoring method makes battery management more scientific and systematic, and can more effectively determine the battery use, charging and recycling strategies, thereby improving resource utilization.

[0091] The charging operation method is to connect the battery to the charging system and monitor the charging process by controlling the charging module; the disabling operation method is to disable the battery through the control module, making it unable to continue to be used and isolating it in the device; updating the battery status record and storing the charging or disabling operation results; feeding back the battery health status and processing results to the display module and the user interaction module to inform the user of the current status of the battery and necessary operation suggestions.

[0092] The charging module and disabling module effectively control the battery usage status, prevent battery overcharging or malfunction, and ensure equipment safety; the monitoring of the charging process ensures that the battery remains in a safe range during charging, and problems are discovered and handled in a timely manner.

[0093] Timely updates of battery status records provide accurate historical data, which helps to track battery health over the long term; feedback of battery status and operation suggestions through the display module and user interaction module ensure that users can obtain the latest battery information and take necessary actions in a timely manner; automated charging and disabling operations reduce manual intervention and improve system management efficiency and response speed.

[0094] The method for real-time display of battery health status information, battery swap cabinet operation status information and battery charging status is:

[0095] Obtain data from the battery health detection module, the battery swap cabinet operation control system, and the battery charging management system; the data includes the battery's SOH value, current health status, battery charging status, and current operating status of the battery swap cabinet;

[0096] Process the acquired data, including formatting data, calculating statistical values, and logical verification of data;

[0100] Displays the battery charging progress and status, including charging, charging complete, and charging failure, and uses a progress bar, percentage, or status icon to indicate this.

[0101] Real-time display of battery SOH value, health status, charging status and battery swap cabinet operation status, providing users with comprehensive equipment status information to ensure that users can quickly understand the equipment status; by formatting data, calculating statistical values ​​and logical verification, the accuracy and readability of information are improved, and data errors and display errors are reduced.

[0102] Use color coding and status icons to indicate battery health status and charging progress, making information more intuitive and easy to understand, and improving user experience; display the operating status and charging progress of the battery swap cabinet to help users understand the equipment status in a timely manner and quickly respond to possible problems, such as system fault warnings or charging failures; progress bars and percentages indicate the charging status, making the charging progress clear at a glance, making it easier for users to track and manage the charging process.

[0103] The method for users to interact with the smart battery swap cabinet is:

[0104] The user enters the locker password or requests authorization through the touch screen or voice command, and the system converts the voice into text through the voice recognition module;

[0105] The system compares the password entered by the user with the preset password in the database;

[0106] After the user submits a battery replacement request, the system verifies the user's permissions through the background and authorizes the battery replacement operation;

[0107] Display operation results and system feedback information on the touch screen, including battery swap authorization confirmation and operation progress;

[0108] The voice recognition system provides feedback information through voice broadcast, including operation success and authorization status.

[0109] It supports two input methods: touch screen and voice command, which can meet the needs of different users and improve the convenience of operation. It ensures the security of battery replacement operation through password comparison and permission verification to prevent unauthorized use. The touch screen and voice recognition system provide operation results and system feedback information, so that users can quickly understand the operation status and progress.

[0110] Voice broadcast and touch screen information display provide an intuitive and friendly user experience and reduce operational complexity; the integration of voice recognition and background verification systems improves operational efficiency and ensures operational accuracy and system stability.
