[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] This utility model provides a technical solution: a multi-parameter monitoring device for an energy storage system. Please refer to [link / reference]. Figures 1 to 7 A multi-parameter monitoring device for an energy storage system includes at least one set of sensors 2 installed on the outside of the energy storage device 7, and at least one electrochemical gas sensor 4.
[0031] Sensor 2 includes an acoustic emission sensor and a temperature sensor configured in the same group, wherein at least two acoustic emission sensors and temperature sensors are configured in the same group;
[0032] Electrochemical gas sensor 4 is installed on top of the corresponding energy storage device 7. Electrochemical gas sensor 4 is installed on top of monitoring box 3, and is separated by a partition 35 fixed on top of monitoring box 3.
[0033] Based on the above structure, a multimodal sensor fusion model is formed by sensor 2 and electrochemical gas sensor 4. On the one hand, the redundant design of sensor 2 ensures that the system can still work normally when a single sensor fails. On the other hand, the high-frequency signal generated by the microcrack propagation and temperature change generated by the energy storage device 7 can be monitored by the acoustic emission sensor and temperature sensor set on sensor 2. Through multimodal sensor fusion, the sensitivity and reliability of leak detection are significantly improved.
[0034] Furthermore, by using sensor 2 to capture high-frequency signals generated by the propagation of microcracks in seals or pipelines, and combining this with a temperature sensor to monitor local temperature rise, potential leak points can be quickly located.
[0035] Furthermore, the electrochemical gas sensor 4 is installed on the top of the energy storage device 7 to detect volatile components of the electrolyte or gas leaks (such as hydrogen and oxygen). The electrochemical gas sensor is separated by the partition 35 to avoid interference caused by different types of gases generated in different areas of the energy storage device 7, or to isolate the monitoring of different concentrations of gases generated in different areas, thereby improving the detection accuracy.
[0036] Furthermore, by setting up multiple sensors 2, it is possible to monitor data changes of the energy storage device 7 in different areas of space. Combined with the data monitoring of the electrochemical gas sensor 4, it is possible to quickly predict fault points based on the data correlation between the sensor and the electrochemical gas sensor 4, thereby further improving the accuracy of data acquisition and the accurate location of fault points.
[0037] Based on the above structure, the monitoring steps include:
[0038] S1. Construct data models of support 1, monitoring box 3 and energy storage device 7, and generate corresponding three-dimensional spatial models or cut two-dimensional planar models;
[0039] S2. Construct a data model based on the material type, thermal conductivity, and other material properties of the energy storage device 7;
[0040] S3. Based on the material characteristics of the energy storage device 7, and through the data changes obtained by the sensor 2 and the electrochemical gas sensor 4, the leakage point or high temperature point is monitored.
[0041] S4. Establish a historical database and experience data. Based on the established database and experience data, add weights to the points where the energy storage device 7 fails during temperature monitoring, so as to realize the weight values for subsequent failures.
[0042] S5. Based on the weight values, the failure points can be predicted, and the prediction results can be fed back to the production and R&D process to improve the yield rate and reduce the occurrence of leakage and abnormal temperature.
[0043] As an optional embodiment, refer to the appendix Figure 3 The side of the monitoring box 3 includes side plates 32 that are spliced together. A through hole is provided on the bottom side of the side plate 32, and the through hole here is connected to the through hole on the surface of the top plate 31 through the inner cavity of the monitoring box 3. The through hole is located on the outer periphery of the electrochemical gas sensor 4.
[0044] Furthermore, multiple brackets 1 are provided on the outside of the monitoring box 3, and the brackets 1 are provided with sliding grooves for sliding installation of multiple sensors 2.
[0045] Furthermore, a base plate 5 is provided at the bottom of multiple side plates 32, and a support platform 6 is movably installed on the top of the base plate 5. The support platform 6 abuts against the bottom of the energy storage device 7. The movable design of the support platform 6 makes it easy to adjust the height of the energy storage device to adapt to different application scenarios.
[0046] According to the above structure, the through hole is located on the periphery of the electrochemical gas sensor 4, which is used to achieve uniform rise of airflow and drive the energy storage device 7 to generate uniform rise of gas. The through hole can also be a dense hole, that is, the top plate 31 is a mesh structure, which can achieve smooth rise of gas. However, it is necessary to consider factors such as the influence of different airflow changes, the influence of temperature, and the influence of generated gas on the top plate 31 in the test environment.
[0047] It should be noted that the bottom fixing method of bracket 1 includes, but is not limited to, fixing by bolts, magnetic fixing, adhesive fixing, etc. The installation method can also be fixed by welding or other methods. Floating installation is preferred to enable monitoring of energy storage devices 7 of different specifications, thereby improving versatility and practicality.
[0048] When there is only one electrochemical gas sensor 4, the through hole is set to be annular, and the through hole is set as close as possible to the side of the mounting plate 31 of the electrochemical gas sensor 4.
[0049] In addition, through holes are provided at the bottom of the side panel 32, which allows gas to be transported into the monitoring box 3 through the bottom, and the energy storage device 7 is raised by the support platform 6, which improves the uniformity of the gas flowing into the monitoring box 3 and improves the accuracy of gas monitoring.
[0050] Furthermore, to ensure uniform gas delivery, multiple vertically upward venting holes can be provided on the surface of the base plate 5.
[0051] See attached document Figure 3 The side plate 32 has a slot 33 for inserting the end of the sensor 2, and at least one side plate 32 has a slot 34 for accommodating wires, through which the wires connected to the energy storage device 7 in the test state are connected.
[0052] As an optional embodiment, refer to the appendix Figure 5-7The sensor 2 includes an inner ring 22 and a housing 21 that is threadedly installed on the outer side of the inner ring 22. The end of the inner ring 22 is provided with a locking block 23 that slides and engages with the slide groove. Installation is achieved by the tight fit between the locking block 23 and the slide groove.
[0053] As an optional embodiment, the screw rotation of the housing 21 and the inner ring 22 is used to adjust the clamping space between the clamping block 23 and the end of the housing 21. The contraction of the clamping space is used to clamp the outer wall of the slide groove, thereby realizing the positioning and installation of the sensor 2.
[0054] As an optional embodiment, the side of the locking block 23 opposite to the locking block 23 is provided with an annular array of shrink heads 24. When the housing 21 and the inner ring 22 are threadedly installed, the inner wall of the housing 21 abuts against the outer side of the shrink heads 24, causing the annular shrink heads 24 to shrink. The outer diameter of the annular shrink heads 24 is larger than the inner diameter of the housing 21, which can realize the shrinkage of multiple annular shrink heads 24 during the installation of the housing 21 and the locking block 23. This can realize the installation and positioning of the acoustic emission sensor or temperature sensor after installation, or the positioning and installation of sensors with different diameters, improving the stability of the sensor after installation and improving the accuracy of data monitoring.
[0055] In addition, multiple sensors 2, electrochemical gas sensors 4 and energy storage device 7 are connected to at least one set of data acquisition modules and edge computing modules, as well as at least one data processing module, via wires.
[0056] According to the above structure, the data acquisition module is connected to the sensor 2, the electrochemical gas sensor 4 and the energy storage device 7. The data changes of the energy storage device 7 during the monitoring process are transmitted to the data processing module or directly to the edge computing module through wires. The data processing module constructs a monitoring model based on the various data changes of the energy storage device 7, and reflects the real-time data changes in the monitoring model. Alternatively, the edge computing module sets alarm information and risk warning information based on the data changes and the set data thresholds.
[0057] Furthermore, the edge computing module incorporates an adaptive algorithm that integrates data such as acoustic emission, temperature, and gas concentration to dynamically adjust alarm thresholds, reduce false alarm rates, and enhance system response speed through real-time processing capabilities, providing reliable support for fault diagnosis and early warning.
