[0071] Through the above-mentioned drawings, the clear embodiments of the present application have been shown, and more detailed descriptions will be given later. These drawings and text descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0072] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0073] Before introducing the embodiments of the present application, the application background of the embodiments of the present application will be explained first:

[0074] Lead-acid batteries are the backup power sources for the secondary DC power supply system of substations. Lead-acid batteries convert electrical energy into chemical energy for storage and quickly convert chemical energy into electrical energy for release when needed. The voltage of the DC power supply system in substations is generally 110V or 220V, and the standard voltage of a single lead-acid battery is 2V. Therefore, generally 54 or 108 single batteries are connected in series and installed on the battery rack. However, during the long-term floating charge operation of lead-acid batteries, the active substances inside the batteries and the overall performance of the batteries change slowly. When the change in battery performance accumulates to a certain extent, it will be accompanied by a decline in the overall performance of the battery pack, posing a risk of causing the overall loss of voltage in the secondary DC power supply system of the substation. Therefore, it is an effective measure to prevent system failures caused by abnormal battery packs to detect potential risks of single batteries with abnormal shells and deteriorated performance as early as possible through technical means.

[0075] Figure 1Side view of the expansion of the battery case provided by the embodiment of the present application Figure 2 Top view of the expansion of the battery case provided by the embodiment of the present application, as Figure 1 and Figure 2 shown. When the battery includes battery terminal posts (including positive and negative electrodes) and there is a relatively large amount of gas evolution and heat generation in the battery, if the gas overflow valve of the battery is not opened in time, it will cause the battery body to expand outward under the action of the internal gas pressure of the battery until the inside of the battery cracks and releases gas.

[0076] In the prior art, the method of manual inspection is used to monitor the position information and abnormal conditions of the abnormal single battery in the battery pack. This method has the technical problems of low accuracy and low efficiency in abnormal monitoring of the battery pack.

[0077] In view of the technical problems existing in the prior art, the inventors of the present application have the following idea. Since the failure to timely discharge the internal chemical gas of the battery will cause deformation of the battery case, that is, the angular position information of the battery case will change. If the angular position information of the battery case can be quickly and accurately collected and alarm information is generated based on the angular position information exceeding the threshold, the above technical problems can be solved. Therefore, it can be considered to configure a gyroscope sensor on the battery, and judge the change of the angular position information of the corresponding single battery case according to the angular position information collected by the gyroscope sensor in real time. The angular position information exceeding the threshold is determined as an abnormality of the battery case, and corresponding alarm information is generated for the detection result of the abnormal battery, solving the problem of low accuracy and low efficiency in abnormal monitoring of the single battery in the battery pack by the manual inspection method used in the prior art.

[0078] Specifically, Figure 3 Schematic diagram of the system structure for abnormal monitoring and positioning of the battery pack provided by the embodiment of the present application, as Figure 3 shown. A brief introduction to the method involved in the embodiment of the present application is as follows:

[0079] The system structure includes: a battery pack, a gyroscope sensor, a distributed processor, and a battery status monitoring system.

[0080] Among them, the gyroscope sensor is used to collect the angular position information of each single battery in the battery pack, the distributed processor is used to process the angular position information collected by the gyroscope sensor, and the battery status monitoring system is used to control the distributed processor to obtain the angular position information, then compare the angular position information with a preset alarm threshold, and generate alarm information and display the alarm information according to the detection result.

[0081] Among them, the parts not elaborated in detail are disclosed in the following embodiments.

[0082] Next, the technical solution of the present application will be described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0083] It is worth noting that: the application fields of the abnormal monitoring and positioning method, device and electronic device of the battery pack provided in the embodiments of the present application are not limited.

[0084] Among them, the execution subject of the present application is the relevant hardware device configured with the battery state monitoring system, which may specifically be an electronic device such as a server or a terminal device.

[0085] Figure 4 Flow schematic of the abnormal monitoring and positioning method of the battery pack provided in the embodiments of the present application Figure 1 , as Figure 4 shown, the method may include the following steps:

[0086] Step 21, obtain the first angular position information of at least one single battery in the battery pack.

[0087] Among them, for each first angular position information, the first angular position information is the real-time angular position information of the corresponding single battery collected by the gyroscope sensor, and the gyroscope sensor is arranged on the corresponding single battery;

[0088] In this step, the battery state monitoring system obtains the first angular position information of at least one single battery in the battery pack, so as to better master the operating conditions of at least one single battery in the battery pack, record and report any abnormal conditions in a timely manner, so as to ensure the normal operation of the battery pack.

[0089] Among them, the first angular position information is the real-time angular position information collected by the gyroscope sensor after data processing, and may include rotation angle information, X-axis tilt angle information, Y-axis tilt angle information, and Z-axis tilt angle information.

[0090] In a possible implementation, the first angular position information of a single battery is a rotation angle of 3°, an X-axis tilt angle of 5°, a Y-axis tilt angle of 3°, and a Z-axis tilt angle of 2°.

[0091] In a possible implementation, Figure 5 Structural schematic of the gyroscope sensor provided in the embodiments of the present application, as Figure 5 shown, the gyroscope sensor includes a sensor, a sensor rubber ring, and a signal transmission line.

[0092] Among them, the sensor rubber ring is used to ensure that the gyroscope sensor can accurately measure the angle change, and can play a role in fixing the sensor, providing buffering and protection. The signal transmission line is used to transmit the data information collected by the gyroscope sensor to an external processing unit (such as a distributed processor, a battery status monitoring system, etc.).

[0093] Optionally, the gyroscope sensor is arranged on the corresponding single battery as: the gyroscope sensor is arranged on the wide surface of the corresponding single battery.

[0094] The wide surface of the single battery is usually the larger plane of the battery. Compared with other smaller or curved surfaces, the wide surface can usually provide a more stable installation base, which helps the gyroscope sensor to more accurately sense the angle attitude change of the battery during operation and reduce the influence of battery vibration or external interference. In addition, installing the gyroscope sensor on the wide surface can provide angular position information change data in a large range, which helps to measure the more accurate shell deformation of the battery.

[0095] Among them, a corresponding gyroscope sensor is arranged on the wide surface of each single battery.

[0096] In a possible implementation, the gyroscope sensor is arranged at the center position of the wide surface of the corresponding single battery.

[0097] In a possible implementation, Figure 6 is the front view of the installation of the gyroscope sensor provided by the embodiment of the present application, Figure 7 is the side view of the installation of the gyroscope sensor provided by the embodiment of the present application, as Figure 6 and Figure 7 shown, the battery includes a battery body, a battery positive electrode, a battery negative electrode, and a gas overflow valve (the opening and closing of the gas overflow valve are used to control the internal pressure of the battery). The gyroscope sensor is installed at the center position of the wide surface of the battery body. The gyroscope sensor installed at this position can more evenly and accurately capture the shell expansion angle change of the battery in different directions and can efficiently obtain the dynamic change of the angular position information of the single battery.

[0098] Step 22: Determine the detection results of at least one single battery according to at least one first angular position information and a preset warning threshold;

[0099] In this step, the battery status monitoring system determines the detection results of at least one single battery according to at least one first angular position information and a preset warning threshold in the battery status monitoring system, so as to be able to judge in real time whether there is a potential abnormality in the single battery and give an early warning.

[0100] Exemplarily, the alarm threshold represents the angular and positional range of the battery under normal use conditions, and the preset alarm threshold is used to determine whether the angular position information of the battery exceeds the safe range.

[0101] The detection result of a single battery can include the position information and angular position information of the single battery.

[0102] Step 23: If the detection result of at least one single battery indicates an abnormality, generate an alarm message.

[0103] In this step, the battery status monitoring system continuously monitors the status of all single batteries. If the detection result of at least one single battery indicates an abnormality, the battery status monitoring system automatically generates an alarm message.

[0104] Among them, the alarm message can include abnormal angular position information, abnormal battery position information, battery abnormality occurrence time, etc.

[0105] In a possible implementation, the alarm message is that the second single battery is abnormal, the abnormal angular position information is that the rotation angle is 11°, the X-axis tilt angle is 11°, the Y-axis tilt angle is 12°, the Z-axis tilt angle is 12°, and the battery abnormality occurrence time is 2:02 on February 2, 2022.

[0106] The abnormal monitoring and positioning method for a battery pack provided by the embodiments of the present application first obtains the first angular position information of at least one single battery in the battery pack, then determines the detection result of at least one single battery according to the at least one first angular position information and the preset alarm threshold. If the detection result of at least one single battery indicates an abnormality, an alarm message is generated. This technical solution realizes the automatic monitoring and positioning of the abnormality of the battery pack by real-time monitoring of the angular position information of at least one single battery in the battery pack, where the angular position information reflects the shell deformation of the single battery, and generates an alarm message corresponding to the single battery with an abnormal shell according to the detection result of the angular position information, ensuring the accuracy rate of the abnormal monitoring and positioning of the battery pack and improving the abnormal monitoring efficiency of the battery pack at the same time.

[0107] Based on the above embodiments, Figure 8 The flow schematic of the abnormal monitoring and positioning method for a battery pack provided by the embodiments of the present application Figure 2 , as Figure 8 shown, step 22 may include the following steps:

[0108] Step 31: For each first angular position information, if the first angular position information is greater than or equal to the first preset threshold, determine the first result as the detection result, where the first result indicates that the single battery corresponding to the first angular position information is abnormal;

[0109] In this step, for the first angular position information of each single battery, compare the first angular position information with the first preset threshold. If the first angular position information is greater than or equal to the first preset threshold, it indicates that the housing state of the single battery corresponding to the above first angular position information may be abnormal, and the battery state monitoring system takes the first result as the detection result.

[0110] Exemplarily, the first preset threshold is the single teleportation threshold.

[0111] In one possible implementation, the first preset threshold is 10°.

[0112] In one possible implementation, the first angular position information of the first single battery is that the rotation angle is 10°, the X-axis tilt angle is 5°, the Y-axis tilt angle is 12°, and the Z-axis tilt angle is 11°. Then the first result is that the position information of the abnormal battery is the first single battery, and the corresponding abnormal angular position information is the rotation angle of 10°, the Y-axis tilt angle of 12°, and the Z-axis tilt angle of 11°.

[0113] Step 32: If the first angular position information is less than the first preset threshold, determine the second result as the detection result, where the second result indicates that the single battery corresponding to the first angular position information is normal.

[0114] In this step, for the first angular position information of each single battery, compare the first angular position information with the first preset threshold. If the first angular position information is less than the first preset threshold, it indicates that the housing state of the single battery corresponding to the above first angular information is in a normal working state, and the battery state monitoring system takes the second result as the detection result.

[0115] Exemplarily, the second result is that the angular position information of the third single battery is that the rotation angle is 4°, the X-axis tilt angle is 5°, the Y-axis tilt angle is 6°, and the Z-axis tilt angle is 2°.

[0116] Optionally, step 22 can be implemented as follows:

[0117] S1: If the sum of multiple second angular position information is greater than or equal to the second preset threshold, determine the third result as the detection result, where the third result indicates that the single battery corresponding to the second angular position information is abnormal;

[0118] In this step, for the second angular position information of each single battery, the sum of multiple second angular position information within a certain time period is compared with a second preset threshold. If the sum of multiple second angular position information is greater than or equal to the second preset threshold, it indicates that there is a potential abnormal risk for the single battery corresponding to the above second angular position information, and the battery state monitoring system uses the third result as the detection result for the corresponding single battery.

[0119] Exemplarily, the second preset threshold is a historical cumulative threshold. The second angular position information is at least one angular position information obtained by real-time data processing for each single battery.

[0120] In a possible implementation, the gyroscope sensor installed on the single battery collects the angular position information of the battery once every 1 minute, and collects the angular position information 10 times in 10 minutes. After accumulating and adding the 10 times of angular position information, it is compared with the second preset threshold to obtain the detection result.

[0121] Among them, the second preset threshold is greater than the first preset threshold. Specifically, the first preset threshold and the second preset threshold can be adjusted correspondingly according to the actual application scenario and the battery characteristics. The embodiments of the present application do not make specific limitations.

[0122] In a possible implementation, the second preset threshold is 20°.

[0123] Exemplarily, the sum of the angular position information collected by the fourth single battery in 10 minutes is that the rotation angle is 22°, the X-axis tilt angle is 20°, the Y-axis tilt angle is 15°, and the Z-axis tilt angle is 12°. Then the third result is that the position information of the abnormal battery is the fourth single battery, and the corresponding abnormal angular position information is the rotation angle of 22° and the X-axis tilt angle of 20°.

[0124] S2. If the sum of multiple second angular position information is less than the second preset threshold, determine the fourth result as the detection result, and the fourth result indicates that there is no abnormality in the single battery corresponding to the second angular position information.

[0125] In this step, for the second angular position information of each single battery, the sum of multiple second angular position information within a certain time period is compared with the second preset threshold. If the sum of multiple second angular position information is less than the second preset threshold, it indicates that there is no potential abnormal risk for the single battery corresponding to the above second angular position information, and the battery state monitoring system uses the fourth result as the detection result.

[0126] Exemplarily, the fourth result is that the sum of the angular position information collected by the fifth single battery in 10 minutes is that the rotation angle is 10°, the X-axis tilt angle is 8°, the Y-axis tilt angle is 15°, and the Z-axis tilt angle is 12°.

[0127] The abnormal monitoring and positioning method for a battery pack provided by an embodiment of the present application. For each first angular position information, if the first angular position information is greater than or equal to a first preset threshold, the first result is determined as the detection result, and the first result indicates that the single battery corresponding to the first angular position information is abnormal. If the first angular position information is less than the first preset threshold, the second result is determined as the detection result, and the second result indicates that the single battery corresponding to the first angular position information is normal. This technical solution monitors the angular position information of the single battery and compares it with a preset threshold to generate a detection result corresponding to the single battery, realizing the abnormal monitoring of the single battery, and can timely and automatically discover possible safety hazards of the battery pack, ensuring the stability and safety of the battery pack.

[0128] Based on the above embodiment, Figure 9 The flow diagram of the abnormal monitoring and positioning method for a battery pack provided by an embodiment of the present application Figure 3 , such as Figure 9 shown, step 21 may include the following steps:

[0129] Optionally, before step 21, the following implementation may be available:

[0130] S1. For each single battery, obtain the initial angular position information of the single battery;

[0131] In this implementation, the angular position information of the battery is collected by using a gyroscope sensor arranged on each single battery, and the first collected angular position information is used as the initial angular position information.

[0132] In a possible implementation, the initial angular position information corresponding to the first single battery is that the rotation angle is 1°, the X-axis tilt angle is 0°, the Y-axis tilt angle is 1°, and the Z-axis tilt angle is 0°.

[0133] S2. Initialize the angular position information of the gyroscope sensor corresponding to the single battery according to the initial angular position information.

[0134] In this implementation, the battery state monitoring system initializes the angular information of each single battery in the battery dynamic monitoring system according to the initial angular information of each single battery, facilitating the subsequent continuous detection of abnormal conditions of the battery housing.

[0135] Exemplarily, the initialization is that the battery state monitoring system uniformly sets the angular information of the corresponding single battery in the battery state monitoring system to 0 according to the initial angular information of each single battery.

[0136] Step 41: For each individual battery, obtain the third angular position information collected by the gyroscope sensor on the individual battery through the distributed processor.

[0137] Among them, the distributed processor is connected to the gyroscope sensor.

[0138] In this step, the gyroscope sensor set on each individual battery collects the third angular position information of the battery, and then the distributed processor obtains the third angular position information corresponding to each individual battery.

[0139] Exemplarily, the third angular position information is the third angular position information of the individual battery collected by the gyroscope sensor in real time.

[0140] The gyroscope sensor is connected to the distributed processor through a signal transmission line, and the gyroscope sensor corresponding to each individual battery is connected to a corresponding distributed processor.

[0141] In a possible implementation, the distributed processor can be located at any position on the individual battery.

[0142] Step 42: Preset-process the third angular position information through the distributed processor to obtain the first angular position information.

[0143] Among them, the preset processing includes: filtering, amplification, analog-to-digital conversion, and data calculation processing.

[0144] In this step, the distributed processor performs preprocessing such as filtering, amplification, analog-to-digital conversion, and data calculation on the third angular position information to obtain more accurate and effective first angular position information.

[0145] Exemplarily, the processing of filtering, amplification, and analog-to-digital conversion is performed by the analog-to-digital conversion device in the distributed processor, and the data calculation processing is completed by the signal processor in the distributed processor.

[0146] The above filtering is used to remove noise or unwanted signals in the signal collected by the gyroscope sensor, and one or more of low-pass filtering, high-pass filtering, Kalman filtering, median filtering, etc. can be used. Amplification is an operation to amplify the signal, which is usually required when the amplitude of the signal is small and difficult to process. Analog-to-digital conversion is the process of converting the analog signal output by the sensor into a digital signal, ensuring that the analog signal collected by the sensor can be read and further processed by the battery state monitoring system. Data calculation processing is to perform integral calculation, attitude estimation, etc. on the angular position information after being processed by the analog-to-digital conversion device.

[0147] Step 43: Obtain the first angular position information corresponding to each individual battery.

[0148] In this step, the first angular position information corresponding to different individual batteries may be different. The battery state monitoring system acquires the first angular position information corresponding to each individual battery for further analysis and judgment of the abnormal state of the individual battery.

[0149] Optionally, Figure 10 is a schematic diagram of data transmission of the distributed processor provided in the embodiment of the present application. As Figure 10 shown, step 43 can be implemented as follows:

[0150] For the current distributed processor, obtain the first angular position information respectively obtained by the previous i distributed processors through the current distributed processor, and send the first angular position information respectively obtained by the previous i distributed processors and the first angular position information obtained by the current distributed processor to the next distributed processor.

[0151] Wherein, i is a positive integer less than N, and N is the total number of all current distributed processors.

[0152] In this implementation, the first angular position information corresponding to the current individual battery processed by the current distributed processor is obtained, and at the same time, the first angular position information of the individual batteries corresponding to the previous i distributed processors is obtained. Finally, all the first angular position information in the current distributed processor is sent to the next distributed processor.

[0153] When the next distributed processor is the Nth distributed processor, obtain the first angular position information respectively obtained by the previous N - 1 distributed processors sent by the Nth distributed processor and the first angular position information obtained by the Nth distributed processor.

[0154] In this implementation, when all the first angular position information is sent to the last distributed processor (i.e., the Nth distributed processor), the battery state monitoring system obtains the first angular position information respectively obtained by the previous N - 1 distributed processors sent by the Nth distributed processor and the first angular position information obtained by the Nth distributed processor.

[0155] In a possible implementation, there are a total of 10 individual batteries in the battery pack, corresponding to 10 distributed processors. The 10th distributed processor transmits all the first angular position information processed by the previous 9 distributed processors and the first angular position information processed by the 10th distributed processor to the battery state monitoring system.

[0156] The abnormal monitoring and positioning method for a battery pack provided by an embodiment of the present application. In this method, for each single battery, the distributed processor obtains the third angular position information collected by the gyroscope sensor on the single battery. The distributed processor is connected to the gyroscope sensor. Then, the distributed processor performs preset processing on the third angular position information to obtain the first angular position information. The preset processing includes filtering, amplification, analog-to-digital conversion, and data calculation processing. Finally, the first angular position information corresponding to each single battery is obtained. This technical solution inputs the third angular position information collected by the gyroscope sensor corresponding to each single battery into the distributed processor for processing, obtaining accurate and reliable first angular position information, which is used to detect changes in the angular position information of the single batteries in the battery pack, improving the accuracy of abnormal monitoring and positioning of the battery pack, and thus ensuring the safety and stability of the battery pack.

[0157] In a possible implementation, Figure 11 This is the working flowchart of the abnormal monitoring and positioning system for the battery pack provided by the embodiment of the present application. As Figure 11 shown, a specific introduction to the working process of the abnormal monitoring and positioning system for the battery pack is as follows:

[0158] Step 1: Start.

[0159] Step 2: The distributed processor reads the angular position information obtained by the gyroscope sensors corresponding to each single battery.

[0160] Step 3: The battery status monitoring system initializes the angular position information of the gyroscope sensors corresponding to each single battery.

[0161] Step 4: The battery status monitoring system sets the threshold of the angular position information corresponding to the battery.

[0162] Step 5: The distributed processor continuously obtains the angular position information obtained by the gyroscope sensors corresponding to each single battery in real time.

[0163] Step 6: The battery status monitoring system obtains the angular position information processed by the distributed processor.

[0164] Step 7: The battery status monitoring system determines whether the obtained angular position information exceeds the threshold.

[0165] In this step, if it exceeds the threshold, then execute Step 5; if it does not exceed the threshold, then execute Step 8.

[0166] Step 8: The battery status monitoring system displays the detection results of the single battery corresponding to the angular position information that exceeds the threshold.

[0167] Step 9: End.
