[0003] Generally speaking, the performance of a battery is affected by many factors, such as battery temperature, battery internal resistance, number of charge and discharge cycles, discharge current, and discharge method. For batteries that have been stored for a period of time, the storage time and storage temperature will also affect the performance of the battery during use. Therefore, battery packs must be discharged and tested regularly.

The client is connected to the battery management platform server 101 for communication, and the operator can set the discharge control parameters, check the discharge status, receive alarm information, play audio and video data, etc. through the client. The terminal device can be a mobile phone, a PDA, a tablet computer, a desktop computer or a laptop computer, etc.

[0108] The data source module 106 is mainly functionally divided into: a battery signal acquisition module, which is used to acquire battery signals of the battery, mainly including the acquired parameter data such as voltage, current, temperature, humidity, etc. of the battery;

[0109] A discharge control module, used to control the discharge of the battery according to the discharge control parameters in the discharge control instruction issued by the battery management platform server;

[0111] Data uploading module, used to upload the collected data to FSU;

[0112] The alarm module is used to issue an alarm according to the issued alarm instruction when an abnormality is found during security monitoring of the battery management platform server 101.

[0113] The battery management platform server 101 can provide a battery management platform based on the existing SiteWeb6 dynamic environment monitoring system. The functions of the SiteWeb6 dynamic environment monitoring system include real-time data collection, information flow analysis, and data storage. The core technology is to ensure the efficiency of massive data processing and the stability of automatic operation.

[0116] Data unified sharing layer API, providing the interface between the application layer and the underlying functional modules;

[0117] The application layer mainly includes functional applications for various scenarios, AI data analysis, reporting modules, mobile APP services... and third-party applications.

[0118] The above-mentioned scenario function applications may include charging control scenarios and discharge test scenarios. This application is mainly for discharge test scenarios; the AI ​​data analysis function mainly includes: through machine learning, data mining, statistical analysis and other methods, the data stored in the database is analyzed and processed using a pre-trained AI model to obtain performance indicators such as battery usage status, remaining life, and health status.

In this way, the longer the AI ​​model runs, the more realistic the performance indicators predicted by the AI ​​model. The battery management module is also used to provide intelligent decision-making based on the results of AI data analysis.

[0119] The report module of the application layer can realize the report download function, which can query the discharge records and discharge curves of any battery in any period of time in the entire network, and support the download of battery discharge analysis reports.

[0120] The mobile APP service of the application layer supports mobile client login to the battery management platform.

When the battery monitoring alarm occurs, the live picture taken by the camera device can be viewed on the mobile APP; at the same time, the battery discharge status and discharge progress can be viewed on the mobile APP.

[0121] As an optional implementation, the battery management platform server 101 obtains the discharge parameters of the target battery during the discharge process from the data cache sharing module 102, the discharge parameters including at least one of the cell voltage, cell current and cell temperature during the discharge process of the target battery, and obtains the parameter change curve of the cell voltage, cell current and cell temperature of the target battery during the discharge process over time according to the discharge parameters; the parameter change curve is input into the performance prediction model through the battery management module, and after the performance prediction model extracts the features of the parameter change curve, the Kalman filter algorithm is used to predict the performance index of the target battery according to the extracted features, and the performance index includes at least one of the usage identifier, the remaining life and the health score. The usage identifier can be used to determine whether the target battery is currently usable, the remaining life indicates the remaining usage time of the target battery, and the health score is a score between 0 and 100, and the higher the health score, the higher the health of the target battery.

[0122] The above-mentioned performance prediction model is an AI model. The performance indicators obtained include usage status, remaining life, and health status. Training samples can be obtained based on historical data. The training samples include discharge parameters and performance indicators during the battery discharge process. The discharge parameters are input into the AI ​​model, and the model is trained with the performance indicators in the training samples as the target.

[0123] The embodiment of the present application can be used to pre-establish a health model, wherein the health model is constructed through the performance indicators of the battery, and the value ranges of different performance indicators are different. Multiple levels of health models can be set, for example, unhealthy, highly unhealthy, moderately unhealthy, low unhealthy, and healthy levels are set, and the value ranges of each performance indicator corresponding to the health model of different levels are different. In addition, the embodiment of the present application also pre-establishes the discharge test cycle and discharge control parameters corresponding to the health model to realize the formulation of discharge strategies for batteries of different health levels, for example, the lower the health level, the shorter the corresponding discharge test cycle.

[0124] In an embodiment of the present application, the battery management platform server 101 obtains the discharge parameters of the target battery during the discharge process; obtains the performance indicators of the target battery according to the discharge parameters; obtains the target health model corresponding to the performance indicators of the target battery according to the first correspondence between the health model and the performance indicators; obtains the target cycle and target discharge control parameters corresponding to the target health model according to the second correspondence between the health model, the discharge test cycle and the discharge control parameters, and the target cycle is used to determine the next discharge time of the target battery; the target discharge control parameters are used to update the discharge control parameters.

[0125] In order to achieve safe discharge of the battery, the battery management module in the embodiment of the present application can perform a series of tests on the battery during discharge control. Specifically, the relevant parameters that need to be tested can be set, such as battery status detection, battery capacity detection, etc., and the corresponding value range corresponding to the discharge safety can be set to ensure that the battery can be discharged normally. The battery management module can specifically remotely control the discharge of the target battery in the following manner:

[0126] Determining whether the discharge condition is met according to the collected relevant parameters of the target battery and the preset value range of the relevant parameters that meet the discharge condition;

[0127] When the battery parameter of the target battery is within a preset range, sending a discharge control instruction to the controller, wherein the discharge control instruction is used to instruct the controller to control the discharge of the target battery according to the discharge control parameter;

[0128] When it is determined that the discharge end condition in the discharge control parameter is reached, a stop discharge instruction is sent to the controller, where the stop discharge instruction is used to instruct the controller to control the target battery to stop discharging.

[0129] In one possible implementation, the data center operator sends a discharge control instruction to the discharge control module in the data source module 106 through the battery management platform server 101 via the client. The discharge control parameters included in the discharge control instruction may be discharge time, discharge current and other parameters. The controller in the discharge control module adjusts the discharge current and discharge time according to the discharge control instruction to ensure the stability and safety of the battery during discharge. At the same time, during the discharge process, the battery management module will continuously monitor the battery's voltage, current, temperature and other parameters to ensure the safety and stability of the discharge process. The process of the battery management module remotely sending a discharge control instruction to the controller is as follows: Figure 4 shown.

[0130] In the embodiment of the present application, the discharge end condition can be pre-set in the discharge control parameter, and when the battery management module detects that the discharge end condition is reached, it sends a stop discharge instruction to the controller. Exemplarily, the discharge control parameters include the discharge time and the remaining battery power, etc.; when the battery management module detects that the discharge time reaches a preset value, or the remaining battery power exceeds a preset range, it sends a stop discharge instruction to the controller.

[0131] It should be noted that during the remote discharge of the battery, the battery may be over-discharged, the battery may be short-circuited internally, and the battery temperature may be too high or even catch fire and explode due to battery aging. It is necessary to quickly adopt appropriate control strategies and monitoring methods to promptly discover and deal with potential risks and ensure the stability and safety of the system. In the data source module 106 of the present application embodiment, a camera device bound to different batteries is set. The camera device transmits video data to the intelligent video management module. The battery management module analyzes the video data and determines the control instructions. The intelligent video management module controls the camera device. The battery management module of this embodiment is also used to obtain audio and video data during the discharge process of the target battery; according to the audio and video data, the target battery is safely monitored. When receiving the discharge control instruction, the battery management module can determine the target battery according to the discharge control instruction, and control the camera device to be turned on to obtain audio and video data. It can also turn on the camera device to obtain audio and video data before or during discharge according to the control instruction to turn on the camera device.

[0132] As an optional implementation, before the battery management module obtains the audio and video data of the target battery during the discharge process, it is also used to: when the target battery starts to discharge, determine the target camera device corresponding to the camera range of the target battery according to multiple pre-set camera devices and the camera range of each camera device; control the start of the target camera device and focus on the target battery for camera shooting, so that the target battery can be safely monitored by analyzing the audio and video data obtained from the target battery.

[0133] The battery management module performs safety monitoring on the target battery according to the audio and video data, and executes an alarm corresponding to the abnormal frame when the audio and video data includes an abnormal frame; the abnormal frame includes at least one of an image frame with a temperature greater than a threshold, a video frame corresponding to abnormal vibration, an audio frame corresponding to abnormal sound, a video frame corresponding to liquid leakage, and a video frame corresponding to fire and explosion characteristics.

[0134] One possible implementation method for identifying the above abnormal frames is to extract the feature information of the audio and video data through an image feature extraction method; compare the feature information with the preset abnormal range, and if it falls within the range, it is an abnormal frame; another possible implementation method is to use a pre-trained AI model for identifying abnormal frames. The alarm method can be, but is not limited to, email alarm, local sound and light alarm, telephone voice alarm, mobile phone text message alarm, application message alarm, etc.; application messages can be displayed in the form of pop-up windows to facilitate users to find alarms in time.

[0135] The alarm types corresponding to various abnormal frames are as follows:

[0136] 1) Abnormal heating alarm

[0137] The battery management module analyzes the audio and video data of the target battery collected by the camera device, and issues an abnormal heating alarm when it is determined that there is an image frame with a temperature greater than a threshold value;

[0138] The battery will generate a certain amount of heat during the discharge process. If the discharge current is too large, the discharge time is too long, or the battery itself is aged, it may cause the battery to overheat. Overheating may generate corresponding heat or smoke, and the captured image frames will appear abnormal. Therefore, by analyzing the image frames, temperature abnormalities can be discovered in time, and measures can be taken to deal with them, such as stopping discharge or adjusting discharge parameters.

[0139] 2) Abnormal vibration alarm

[0140] The battery management module analyzes the audio and video data of the target battery collected by the camera device, and issues an abnormal vibration alarm when it is determined that there is a video frame corresponding to abnormal vibration;

[0141] 3) Abnormal sound alarm:

[0142] The battery management module analyzes the audio and video data of the target battery collected by the camera device, and when an audio frame corresponding to an abnormal sound is determined, an abnormal sound alarm is issued;

[0143] The data collected by the camera device includes audio data and video data. During the discharge process, the battery may produce abnormal sounds or vibrations. These abnormalities may be caused by loose or damaged internal components of the battery. By monitoring whether abnormal sounds or vibrations are detected by the camera, these abnormalities can be discovered in time and measures can be taken to deal with them, such as stopping discharge or adjusting discharge parameters.

[0144] 4) Liquid leakage alarm

[0145] The battery management module analyzes the audio and video data of the target battery collected by the camera device, and issues a liquid leakage alarm when it is determined that there is a video frame corresponding to liquid leakage;

[0146] During the battery discharge process, the liquid inside the battery pack may leak during the discharge process. Through the video data collected by the camera device, the leakage can be discovered in time according to the characteristics of normal pictures and pictures with leakage, and measures can be taken to deal with it, such as stopping discharge and cleaning the liquid.

[0147] 5) Fire and explosion alarm:

[0148] The battery management module analyzes the audio and video data of the target battery collected by the camera device, and issues a fire and explosion alarm when it determines that there are video frames corresponding to fire and explosion characteristics.

[0149] If a short circuit or overcurrent occurs during the battery discharge process, it may cause serious safety accidents such as fire and explosion. At this time, the camera device can be used to monitor whether there are abnormal conditions such as open flames and thick smoke on the surface of the battery pack to promptly detect the danger of fire and explosion. In extreme cases, the battery pack may cause a fire. Through camera monitoring, smoke or flames in the battery pack can be detected in time, and appropriate emergency measures can be taken to ensure the safety of personnel and property.

[0150] In the embodiment of the present application, the battery management platform server 101 responds to the discharge management instruction and displays the battery management page. The discharge management instruction can be triggered by the manager after logging into the battery management platform through the touch screen of the battery management platform server, or it can be triggered by other personnel after logging into the battery management platform through a terminal device. The battery management interface can be as follows Figure 2 As shown, the battery list displays the battery packs distributed in different positions; in response to the parameter setting instruction generated by the battery management page operation, the discharge control parameter setting page is displayed on the interface, thereby switching to the Figure 3 The discharge control parameter setting interface shown in the figure obtains the discharge control parameters according to the operation on the discharge parameter setting page, and obtains the discharge control instructions according to the discharge control parameters. In the embodiment of the present application, the discharge control parameters include at least one of the following: termination voltage, monomer protection voltage, discharge mode, floating charge voltage or discharge end condition, and the discharge mode includes scheduled discharge mode and immediate discharge mode. In addition, the discharge end condition can also be set. Among them, the termination voltage and the monomer protection voltage can be used as the discharge end condition, specifically:

[0151] Termination voltage: When the total voltage of the battery drops to this point, the floating charge voltage setting is automatically restored and the battery discharge ends. This parameter value can be modified on the interface;

[0152] Single cell protection voltage: When the voltage of any single cell drops to this point, the floating charge voltage setting is automatically restored to end the current battery discharge;

[0153] Scheduled discharge mode: The discharge operation is in the process of being scheduled and the execution time has not yet arrived. This type of reservation can be deleted and the reservation time can be modified.

[0154] Immediate discharge mode: when the scheduled time is up, the system has already performed the floating charge voltage remote adjustment operation (the floating charge voltage is set as the termination voltage);

[0155] Discharge end conditions: When the discharge end conditions are met (the total voltage drops to the termination voltage, a power outage occurs, data sampling is abnormal, etc.), the system remotely adjusts the floating charge voltage to a normal value.

[0156] In an embodiment of the present application, the battery management platform server 101 is also used to: play the audio and video data in a preset manner; the preset manner includes: at least one of pop-up window playback, multi-window playback and patrol switching playback.

[0157] If the pop-up window playback method is adopted, when a security problem is found during the security monitoring process, the audio and video data can be played in the pop-up window playback method for the target battery with the problem.

[0158] If multi-window playback is used, the corresponding audio and video data can be played in multiple windows on the interface for several specified target batteries.

[0159] If a patrol switching playback is adopted, and multiple cameras are started at the same time to focus on different target batteries respectively, the audio and video data obtained by the multiple cameras are played in real time in a patrol switching manner on the patrol interface of the battery management platform.

[0160] Specifically, through the large-screen web display module, a patrol display mode can be supported on the screen connected to the battery management platform server. All batteries can be viewed through the battery list, and the range of target batteries for patrol display can be selected through the battery list, and then displayed on the screen in a patrol mode.

[0161] The battery management module performs safety monitoring on the target battery discharge process, including:

[0162] When it is determined that there is an abnormality in the discharge process of the target battery, an alarm is automatically triggered, and the target battery is remotely controlled to stop the discharge operation;

[0163] The audio and video data acquired by the camera device corresponding to the target battery currently having an abnormality is displayed on the patrol interface of the battery management platform.

[0164] Once an abnormality is found during the patrol process, the target battery with the abnormality will be displayed on the screen. When an abnormality is found during the security monitoring process, this application can establish linkage rules with the camera monitoring to improve the safety and reliability of the battery discharge process. Specifically, the linkage rules can be established in the following ways:

[0165] During the battery discharge process, the camera can automatically start and conduct real-time monitoring, and automatically trigger an alarm when an abnormal situation occurs.

[0166] The embodiment of the present application monitors the status of the battery, including parameters such as voltage, current, and temperature, through a camera device. When an abnormal situation is found, an alarm is immediately activated to remind relevant personnel to deal with it in time; the discharge process of the battery is monitored through a camera device to observe the change in the status of the battery. When an abnormal situation is found, the alarm system is automatically triggered to stop the discharge process; when an abnormal situation is monitored during the battery discharge process, the linkage control system is automatically triggered to adjust or stop the discharge process.

[0167] The specific linkage and remote control process can be as follows:

[0168] When the battery pack discharge test is started, the video system automatically focuses on the battery pack and patrols between multiple battery packs in real time (automatically switching cameras);

[0169] By acquiring the real-time images from the camera device, analyzing and processing the images, possible safety hazards can be identified. By using technologies such as image recognition and artificial intelligence, the monitoring images can be analyzed and processed in real time to quickly and accurately identify possible safety hazards.

[0170] If a safety hazard is found during the battery discharge process, the system will automatically trigger an alarm and stop the discharge operation through the remote control system.

[0171] At the same time, the system can also control the movement of the camera through a remote controller, aim the camera at the location of possible safety hazards, and even activate the 3D positioning function of the camera, which can quickly and accurately capture the details of the battery, so that abnormal batteries can be displayed in the center of the screen, ensuring that safety hazards are discovered and resolved in a timely manner.

[0172] In the embodiment of the present application, the battery management module is also used to: obtain a battery parameter query instruction; the query instruction includes a target regional identifier; from the correspondence between the regional identifier and the battery parameter, obtain the target battery parameter corresponding to the target regional identifier, and display the target battery parameter.

[0173] The relevant parameters of all batteries under the battery management platform are counted and saved in the database. Specifically, the asset information, abnormal battery information, three major states (operating state, capacity state, backup power state), recent discharge records and refresh frequency (such as: 30 seconds) of all battery groups in the entire network can be counted; the interface of the battery management platform provides query methods according to different levels of regional dimensions.

[0174] When receiving the battery parameter query command, the battery under the target region to be queried is determined and the target battery parameters corresponding to the target region identifier are displayed in the form of a battery pack list, such as Figure 2 As shown, the battery pack list can be queried based on four dimensions: city, district, county, station, and working status;

[0175] The battery management platform server is also used through the battery management platform to: obtain the export instruction of the target battery parameters; generate a file including the target battery parameters, and browse the current key performance data of each group of batteries through the query interface, supporting XLS export, etc.

[0176] The following is an example of the processing of a high temperature alarm during battery discharge:

[0177] For example, if there is a 2V battery pack on site in a certain computer room, a group of batteries can be connected to the battery management system as an intelligent device. First, use the configuration tool that comes with the configuration service module to develop a device template for the battery pack. The template contains information about all battery signals, including signal name, unit, signal attributes, etc. At the same time, the template also configures items such as alarm conditions, alarm levels, alarm thresholds, and storage cycles. The configuration in the template is automatically loaded when the system starts.

[0178] If there is a high temperature alarm of a single battery in the system, the system will go to the location of the computer room where the battery pack that generates the high temperature alarm is located, quickly locate the nearby camera device, pop up the real-time video window of the camera device to the front of the screen, and start screenshots and recording. At the same time, the intelligent video management module will start AI analysis. If smoke or irregularities in the battery pack wiring are detected [different alarm rules are preset in the scenes of different cameras. Once the target violates the predefined rules in the scene, the system automatically generates an alarm], it will trigger the highest level of alarm; at the same time, call the alarm notification gateway, send the real-time screenshots and videos of the scene to the relevant maintenance personnel, call the fire alarm, upload GIS location information, and start the control device to automatically open the safety door and sprinkler nozzles. Through real-time video analysis and the use of AI intelligent analysis of real-time alarm information, it is ensured that the operation and maintenance personnel are aware of the on-site situation as soon as possible. The closed loop of battery alarm monitoring events is efficiently completed.

[0179] After the remote discharge of the battery is completed, the system can perform big data analysis and deep learning on the massive discharge data to analyze the remaining capacity of the lagging battery and battery pack. It guides the corresponding maintenance work and provides a basis for parameter tuning and optimization algorithm for the next remote test. If the remote discharge test fails, the specific reason for the test failure will also be recorded, and the corresponding discharge test failure report will be sent to relevant personnel for processing.

[0180] Through the patrol function of the camera device, multiple battery packs that are being discharged at the same time can be monitored in real time. For battery packs with abnormalities, a pop-up display will be displayed, and corresponding alarms (pictures or videos) will be generated to notify front-line maintenance personnel.
