[0028] In addition, such as Figure 1 As shown, the battery cold solder joint detection system may also include a memory 200 for storing data, such as power data, such as target power data, first power data, etc., and full charge status information, such as target full charge status information, first full charge status information, etc.

[0029] It should be noted that, Figure 1The schematic diagram of the battery solder joint detection system shown is merely an example. The battery solder joint detection system and scenario described in this application are for the purpose of more clearly illustrating the technical solutions of this application and do not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will know, with the evolution of battery solder joint detection systems and the emergence of new business scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

[0030] First, this application provides a battery cold solder joint detection method. The execution subject of the battery cold solder joint detection method is a battery cold solder joint detection device, which is applied to a terminal device. The battery cold solder joint detection method includes: acquiring target power data and target full charge status information of the battery during the charging process; determining whether the target power data meets a first condition and whether the target full charge status information meets a second condition; and determining that the battery is in a state of cold solder joint on the tab when the target power data meets the first condition and the target full charge status information meets the second condition.

[0031] like Figure 2 The diagram shown is a flowchart of an embodiment of the battery cold solder joint detection method in this application. The battery cold solder joint detection method may include the following steps S201 to S203, as detailed below: Step S201: Obtain the target battery charge data and target full charge status information during the charging process.

[0032] In this embodiment, the target charge level data refers to the current charge level recorded by the battery during the charging process, reflecting the amount of charge already received. The target full charge status information refers to the system-reported status of whether the battery is fully charged. This data is typically provided by the Battery Management System (BMS) or the charging management module. By monitoring changes in the target charge level during real-time charging and reporting the full charge status, potential problems that may arise during the charging process can be detected promptly.

[0033] Step S202: Determine whether the target power data meets the first condition and whether the target full charge status information meets the second condition.

[0034] Step S203: If the target power data meets the first condition and the target full charge status information meets the second condition, determine that the battery is in a state of poor tab soldering.

[0035] A battery's charging performance is affected by its internal health condition. Batteries in normal working condition typically exhibit a stable charging curve and a consistent charge growth pattern, while batteries with faulty tabs will show abnormal charging data, such as the charge not reaching the expected growth rate or exhibiting abnormal fluctuations in charge level.

[0036] In this embodiment, the first condition can be that the battery level is within a certain range, and the second condition can be that the battery is fully charged. The purpose of this step is to determine whether there is a possibility of a faulty solder joint in the battery by analyzing the charging data. If the battery's charging behavior matches the pre-determined abnormal charging situation, it indicates a hardware failure in the battery. For example, if the battery reports a full charge when its charge level is low, it may mean that there is a faulty solder joint on the battery cell tabs, preventing the battery from charging normally.

[0037] The above steps, by acquiring target charge data and target full charge status information during battery charging, comprehensively judge whether the two data meet the preset conditions, and can determine whether the battery has a problem with poor electrode soldering. By analyzing battery charging data, it avoids complex and cumbersome methods such as disassembling equipment or using infrared detection, and provides a simpler, faster and more effective method for detecting poor battery soldering, improving detection efficiency while reducing the risk of equipment damage and detection costs.

[0038] In one specific implementation, determining whether the target power data meets the first condition includes: if the target power data is lower than or equal to a first threshold, determining that the target power data meets the first condition; if the target power data is higher than the first threshold, determining that the target power data does not meet the first condition.

[0039] This embodiment further details the first condition in step S202, specifically describing how to determine whether the target battery level data meets the first condition. The method for determining whether the target battery level data meets the first condition is to determine whether the target battery level data is lower than or equal to a first threshold. If the target battery level data is lower than or equal to the first threshold, the system determines that the target battery level data meets the first condition; otherwise, if the target battery level data is higher than the first threshold, it is considered that the target battery level data does not meet the first condition. The first threshold can be a preset battery level value, typically set as a certain percentage of the battery level (e.g., 70%).

[0040] In one specific implementation, the first threshold is determined as follows: first charging data of a first sample battery and second charging data of a second sample battery are obtained, wherein the first sample battery is in a state of poor tab soldering and the second sample battery is in a normal working state; the first charging data and the second charging data are compared and analyzed to determine the first threshold.

[0041] In this embodiment, the first threshold is determined based on actual battery charging data. The first sample battery and the second sample battery represent two different states of batteries: the former is a battery with a faulty tab, and the latter is a battery in normal working condition. These two sample batteries provide different charging data for subsequent comparative analysis. The first charging data and the second charging data refer to the charge data recorded by these two sample batteries during the charging process. The first charging data reflects the performance of the battery with the faulty tab during charging, while the second charging data represents the charging data of the normal battery. By comparing and analyzing these two datasets, a reasonable charge threshold can be determined as the first threshold. This value can reflect the difference in charging performance between the normal battery and the battery with the faulty tab, thereby effectively distinguishing between the two and determining whether the battery in actual working condition may have a faulty tab problem.

[0042] In one specific implementation, the first charging data includes first power data and first full-charge status information, and the second charging data includes second power data and second full-charge status information. The first charging data and the second charging data are compared and analyzed to determine a first threshold, including: in the first charging data, determining the charging data corresponding to when the first full-charge status information is the first status information as first sample data; in the second charging data, determining the charging data corresponding to when the second full-charge status information is the first status information as second sample data; and comparing and analyzing the first sample data and the second sample data to determine the first threshold.

[0043] In this embodiment, the method for determining the first threshold is further refined. Both the first charging data and the second charging data contain two parts: one is the power data, which corresponds to the actual power recorded by the battery during the charging process; the other is the full charge status information, which corresponds to whether the battery has reached a fully charged state during the charging process.

[0044] By comparing the full-charge status information in these two sets of charging data, it can be determined which data should be used as the basis for comparison. Specifically, when the first full-charge status information in the first charging data is a specific state (i.e., the first state information), the corresponding charging data is the first sample data; similarly, when the second full-charge status information in the second charging data is also the same first state information, the corresponding charging data is the second sample data. Then, the first sample data and the second sample data are compared and analyzed to determine the first threshold.

[0045] During charging, the increase in battery capacity and the attainment of a fully charged state are closely related. By comparing the different capacity data from two sets of charging data simultaneously at a fully charged state, it can be ensured that the first and second sample data have similar judgment benchmarks during the charging process. Then, based on the different capacity data, the differences between normal batteries and batteries with faulty cell soldering can be identified, resulting in a more reliable capacity threshold.

[0046] In one specific implementation, the first sample data and the second sample data are compared and analyzed to determine the first threshold, including: determining the maximum value in the first sample data and the minimum value in the second sample data; and determining the first threshold among the values ​​between the maximum value and the minimum value.

[0047] This embodiment details the process of determining the first threshold from the first sample data and the second sample data. First, the highest value of the charge data is determined from the first sample data, which corresponds to the maximum charge level of a battery cell with a faulty solder joint when fully charged. Then, the lowest value of the charge data is determined from the second sample data, which corresponds to the minimum charge level of a normal battery when fully charged. A value between these two extreme values ​​is selected as the first threshold. By comparing the extreme values ​​of the two sets of charging data, a charge threshold that accurately reflects the difference between a normal battery and a battery with a faulty solder joint can be effectively determined.

[0048] In one specific implementation, determining whether the target fully charged state information meets the second condition includes: if the target fully charged state information is the first state information, determining that the target fully charged state information meets the second condition, wherein the first state information indicates that the battery is fully charged; if the target fully charged state information is the second state information, determining that the target fully charged state information does not meet the second condition, wherein the second state information indicates that the battery is not fully charged.

[0049] In this embodiment, the target fully charged state information refers to the state identifier reported by the system during the battery charging process, used to characterize whether the battery has reached a fully charged state. Generally, the system reports that the battery has reached a fully charged state when the battery charging reaches the cutoff current. The first state information indicates that the battery is fully charged, that is, the system considers the battery to be fully charged; the second state information indicates that the battery is not fully charged, that is, the system considers the battery to be not fully charged. The determination rule for the second condition is: when the target fully charged state information is the first state information, it is considered to meet the second condition; when the target fully charged state information is the second state information, it is considered to not meet the second condition.

[0050] In one specific implementation, after determining that the battery is in a state of poor tab soldering, the method further includes: displaying poor tab soldering information, wherein the poor tab soldering information is used to prompt the user of the battery; and / or, marking the battery as being in a state of poor tab soldering.

[0051] In this embodiment, after determining that the battery is in a state of tab poor soldering, the tab poor soldering information can also be displayed, and / or the battery can be marked as being in a state of tab poor soldering. The purpose is to promptly transmit this information to the user or equipment maintenance personnel after the battery is confirmed to have tab poor soldering, so that appropriate measures can be taken.

[0052] A faulty solder joint on a battery tab can be a notification or warning generated by the terminal device, indicating that the battery may not be functioning properly or that there is a potential safety risk. This information can be conveyed to the battery user or relevant personnel through methods such as displaying it on the device screen, emitting an alert sound, or sending a push notification.

[0053] Marking a battery as having a faulty tab connection means adding a clear mark or label to the battery's status record to indicate that the battery has been diagnosed with a faulty tab connection. This mark can be stored in the battery management system or displayed on the device's interface. The purpose of this mark is to provide a clear fault indication for device users or maintenance personnel, facilitating subsequent repair, handling, or battery replacement.

[0054] As a specific implementation, charging data from normal batteries and batteries with faulty solder joints can be collected first as experimental data, and then the experimental data can be analyzed. For example... Figure 3 The diagram shows the charging current, charging voltage, and charging capacity as a function of charging time at room temperature. The horizontal axis represents time in seconds, and the vertical axes represent current (mA), voltage (mV), and capacity (percentage). It can be seen that when charging reaches the cutoff current, the capacity of the battery with the faulty tab can only reach a maximum of 59%, and the charging time from 1% to the charging cutoff is also shorter. Figure 4 The diagram shows the discharge current, discharge voltage, and discharge capacity as a function of discharge time at room temperature. The horizontal axis represents time (hours:minutes:seconds), and the vertical axes represent current (mA), voltage (mV), and capacity (percentage), respectively. It can be seen that the battery with poorly soldered tabs has its battery life reduced by nearly half, and it shuts down at 20% charge. Figure 5The diagram shows the charging voltage and charge amount as a function of charging time at high temperatures. The horizontal axis represents time (hours:minutes:seconds), in seconds, and the vertical axis represents voltage (millivolts) and charge amount (percentage). It can be seen that the charging curves of normal batteries and batteries with faulty tabs are almost identical at both room temperature and high temperature. When charging is triggered to the cutoff current, the charge amount of the battery with faulty tabs can only reach a maximum of 58%. Analyzing the above experimental data, we can select the fully charged state information as the charge amount when fully charged, that is, the battery charge amount corresponding to the time when charging stops at the charging cutoff current. The minimum charge amount for a normal battery is close to 100%, while the maximum charge amount for a battery with faulty tabs is 59%. We can select 70% as a threshold to determine whether the battery is normal or has faulty tabs.

[0055] like Figure 6 As shown, in practical applications, when a charger is detected to be plugged in, a faulty solder joint detection thread can be started. Then, the thread is set to detect the current battery level and full charge status every 20 seconds. It is determined whether the current battery level is less than 70% and whether the battery is fully charged (whether charging has stopped). If the determination is yes, the cell is marked as having a faulty solder joint, and the user is notified and the faulty solder joint is displayed. Otherwise, the system waits for the next detection.

[0056] To better implement the battery cold solder joint detection method in this application embodiment, based on the battery cold solder joint detection method, this application embodiment also provides a battery cold solder joint detection device, such as... Figure 7 As shown, the battery solder joint defect detection device 700 includes: The acquisition module 710 is used to acquire target battery power data and target full charge status information during the charging process; The first determining module 720 is used to determine whether the target power data meets the first condition and whether the target full charge status information meets the second condition. The second determining module 730 is used to determine that the battery is in a state of poor tab soldering when the target power data meets the first condition and the target full charge status information meets the second condition.

[0057] In this embodiment of the application, by acquiring the target power data and target full charge status information during the battery charging process, when the target power data and target full charge status information simultaneously meet the corresponding preset conditions, it can be confirmed that the battery is in a state of poor tab soldering. This avoids the complexity and inconvenience of disassembling equipment or relying on professional equipment in traditional methods, improves the convenience of detection, and greatly reduces the cost and time of detection.

[0058] In some embodiments of this application, the first determining module 720 determines whether the target power data meets a first condition, including: If the target power data is lower than or equal to the first threshold, the target power data is determined to meet the first condition. If the target power data is higher than the first threshold, it is determined that the target power data does not meet the first condition.

[0059] In some embodiments of this application, the battery solder joint detection device 700 determines the first threshold in the following manner: Acquire the first charging data of the first sample battery and the second charging data of the second sample battery, wherein the first sample battery is in a state of poor electrode soldering and the second sample battery is in a normal working state. The first charging data and the second charging data are compared and analyzed to determine the first threshold.

[0060] In some embodiments of this application, the first charging data includes first power data and first full charge status information, and the second charging data includes second power data and second full charge status information. The battery solder joint detection device 700 compares and analyzes the first charging data and the second charging data to determine a first threshold, including: In the first charging data, the charging data corresponding to the determination that the first fully charged state information is the first state information is the first sample data; In the second charging data, the charging data corresponding to the determination that the second full charge status information is the first status information is the second sample data; The first and second sample data are compared and analyzed to determine the first threshold.

[0061] In some embodiments of this application, the battery solder joint detection device 700 compares and analyzes first sample data and second sample data to determine a first threshold, including: Determine the maximum value in the first sample data and the minimum value in the second sample data; Determine the first threshold value from the range between the maximum and minimum values.

[0062] In some embodiments of this application, the first determining module 720 determines whether the target fully charged state information meets the second condition, including: If the target fully charged state information is the first state information, it is determined that the target fully charged state information meets the second condition, wherein the first state information represents that the battery is fully charged. If the target fully charged state information is the second state information, it is determined that the target fully charged state information does not meet the second condition, wherein the second state information indicates that the battery is not fully charged.

[0063] In some embodiments of this application, after determining that the battery is in a state of tab poor soldering, the battery poor soldering detection device 700 is further configured to: display tab poor soldering information, wherein the tab poor soldering information is used to prompt the user of the battery; and / or, mark the battery as being in a state of tab poor soldering.
