[0044] In the prior art, there are a large number of energy storage modules in the energy storage monitoring system, which undertake the extremely important key task of storing and releasing electric energy. During the operation of the energy storage module, the energy storage elements in the energy storage module usually encounter a series of difficult situations such as overcharging, over-discharging and overheating.

[0046] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. 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. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0047] Figure 1 A schematic diagram of the structure of an energy storage monitoring system provided in an embodiment of the present application Figure 1 ,like Figure 1 As shown, the energy storage monitoring system 10 includes: multiple energy storage modules 101, energy storage monitoring modules 102, multiple temperature monitoring modules 103 and multiple semiconductor heat dissipation modules 104, wherein the energy storage monitoring module 102 is respectively connected to the temperature monitoring module 103 and the semiconductor heat dissipation module 104 through optical fibers. The energy storage module 101 includes multiple energy storage elements 105 and multiple energy storage converters 106, and the energy storage elements 105 are correspondingly connected to the energy storage converters 106 through optical fibers, and adjacent energy storage elements 105 are connected through optical fibers.

[0048] The energy storage element 105 is used to store or release electric energy, and the energy storage converter 106 is used to convert the electric energy into AC or DC according to the way the energy storage element 105 stores or releases electric energy.

[0049] In this embodiment, the energy storage element is a device that can store electrical energy. The energy storage element stores electrical energy in the form of chemical energy, electric field energy, etc., and releases it when needed. The energy storage element may include, for example, batteries (such as lithium-ion batteries, lead-acid batteries, etc.), supercapacitors, etc. The energy storage inverter is a key device that connects the energy storage element and the power grid or other electrical equipment. The energy storage inverter converts electrical energy between AC and DC according to the needs of the energy storage element to store or release electrical energy. When the energy storage element stores electrical energy, the energy storage inverter converts the AC power of the power grid into DC power suitable for the energy storage element for storage; when the energy storage element releases electrical energy, it converts the DC power output by the energy storage element into AC power for use by the power grid or other equipment.

[0050] The temperature monitoring module 103 is used to monitor the temperature of the energy storage element 105 during operation and send the temperature to the energy storage monitoring module 102. One temperature detection module 103 monitors one energy storage element 105 and is fixed to the outside of the energy storage element 105 by direct contact.

[0051] In this embodiment, the temperature monitoring module is fixed on the outside of the energy storage element in direct contact to monitor the real-time temperature of the energy storage element during operation to ensure accurate temperature information. This direct contact method can reduce measurement errors and quickly reflect the temperature changes of the energy storage element, thereby ensuring that the energy storage element operates safely and stably within an appropriate temperature range and avoiding adverse effects of excessively high or low temperatures on its performance and life.

[0052] It should be noted that the temperature monitoring module may be, for example, an integrated temperature sensor chip, a thin film temperature sensor, a piezoelectric temperature sensor, etc.

[0053] The energy storage monitoring module 102 is used to receive the temperature, analyze the temperature with a preset temperature threshold, obtain an analysis result, and control the semiconductor heat dissipation element 104 and the energy storage element 105 in sequence according to the analysis result.

[0054] In this embodiment, the energy storage monitoring module has data receiving function, analysis and comparison function and control instruction issuing function. Data receiving function: can accurately receive temperature data from the temperature monitoring module. Analysis and comparison function: can compare and analyze the received temperature with the preset temperature threshold in detail to determine whether the current temperature condition is within the normal range. Control instruction issuing function: based on the analysis results, issue corresponding control instructions to the semiconductor heat dissipation element and the energy storage element to achieve temperature regulation and management of the working status of the energy storage element.

[0055] The semiconductor heat dissipation module 104 is used to dissipate heat for the energy storage element 105 and is fixed around the energy storage element 105 in a direct contact manner.

[0056] In this embodiment, the semiconductor material properties of the semiconductor heat dissipation module can be used to quickly and effectively dissipate the heat generated by the energy storage element, keeping it working within a suitable temperature range. The semiconductor heat dissipation module is in close contact with the energy storage element to ensure good heat conduction efficiency and take away the heat in time.

[0057] In a possible implementation, the energy storage monitoring module 102 in the energy storage monitoring system 20 includes a main EMS server 201, a backup EMS server 202, and a main-backup switching device 203, and the main-backup switching device 203 is connected to the main EMS server 201 and the backup EMS server 202 via optical fibers. The main-backup switching device 203 includes a self-checking module 204, a processing module 205, and a switching module 206. Figure 2 As shown, Figure 2 A schematic diagram of the structure of an energy storage monitoring system provided in an embodiment of the present application Figure 2 .

[0058] The main EMS server 201 is used to receive the temperature, analyze the temperature with the preset temperature threshold, obtain the analysis result, and control the semiconductor heat dissipation element and the energy storage element in turn according to the analysis result; the backup EMS server 202 is used to replace the main EMS server when the main EMS server fails or is abnormal.

[0059] In this embodiment, the main EMS server and the backup EMS server cooperate with each other in the energy storage monitoring system. The backup EMS server ensures that when the main EMS server fails, the system can still operate stably and will not interrupt the service due to a single point failure, thereby reducing the risk of data loss or business interruption caused by the failure. Among them, the Energy Management System (EMS) server is also used to monitor, analyze and control the use and management of energy. For example, the EMS server can also collect data from various energy-related equipment to monitor the energy consumption in real time.

[0060] It should be noted that the main EMS server and the backup EMS server run simultaneously and perform data synchronization in real time, wherein running simultaneously means that both the main EMS server and the backup EMS server are powered on and working. A dual network mode can be adopted between the main EMS server and the backup EMS server. When one of the networks fails, the other network can continue to ensure data transmission and communication, thereby improving the stability and availability of the entire system.

[0061] The active / standby switching device 203 is used to perform switching processing between the active EMS server and the standby EMS server.

[0062] In this embodiment, the active-standby switching device plays a key bridge role in the energy storage monitoring system. The active-standby switching device can intelligently perform switching operations according to the operating status of the main EMS server. When the main EMS server is working normally, the active-standby switching device ensures that the system runs stably through the main EMS server; and once a problem occurs with the main EMS server, the active-standby switching device can quickly and accurately switch the system to the standby EMS server to ensure uninterrupted operation of the system. Such a device improves the fault tolerance and reliability of the system, making the operation of the entire system more stable and secure, and avoiding adverse consequences such as business interruption or data loss that may be caused by server failures.

[0063] The self-check module 204 is used to check the hardware circuits in the main EMS server and the connection status between the main EMS server and the energy storage module, the temperature detection module, and the semiconductor heat dissipation module, obtain the self-check results, and send the self-check results to the processing module.

[0064] In this embodiment, the self-check module conducts a comprehensive check on the hardware circuits in the main EMS server to ensure that these circuits are in normal working condition and there are no faults or hidden dangers. Among them, the hardware circuits in the main EMS server can be, for example, whether the hardware working current and voltage are normal. At the same time, the self-check module will also detect the connection status between the main EMS server and the energy storage module, the temperature detection module, and the semiconductor heat dissipation module. The self-check module sends the self-check results obtained by the detection to the processing module in a timely manner, so that the processing module can make corresponding decisions and processes based on this information, so as to promptly discover and solve possible problems and ensure the stable and reliable operation of the entire system.

[0065] For example, the self-check module may use a monitoring tool or a script to perform real-time monitoring on the main EMS server.

[0066] The processing module 205 is used to determine whether a fault or abnormality occurs in the main EMS server according to the self-check result and the preset standard, and if so, send the fault or abnormality to the switching module.

[0067] In this embodiment, after receiving the self-test result from the self-test module, the processing module will compare and analyze it with the preset standard. If the self-test result shows that the main EMS server does not meet the standard, such as a fault or abnormal state, the processing module will quickly sort out these faults or abnormal conditions and send them to the switching module.

[0068] The switching module 206 is used to switch the main EMS server and the backup EMS server according to a fault or abnormal situation.

[0069] In this embodiment, the switching module timely understands the status of the main EMS server so as to take corresponding countermeasures, such as starting the backup EMS server, thereby minimizing the impact on the operation of the entire system and ensuring the stability and continuity of the system.

[0070] In a possible implementation, the energy storage monitoring module in the energy storage monitoring system is specifically used to determine whether the temperature reaches a first preset temperature threshold. If so, the difference between the temperature and the first preset temperature threshold is calculated, and based on the difference, the working intensity of the semiconductor heat dissipation element for dissipating heat from the energy storage element is adjusted.

[0071] In a possible implementation, the energy storage monitoring module in the energy storage monitoring system is also specifically used to determine whether the current temperature of the energy storage element reaches a second preset temperature threshold. If so, the energy storage element is controlled to be disconnected from the external power supply device. The current temperature refers to the temperature of the energy storage element when the semiconductor heat dissipation element performs heat dissipation treatment on the energy storage element and the second preset temperature threshold is greater than the first temperature threshold.

[0072] Figure 3A schematic diagram of a method for monitoring energy storage provided in an embodiment of the present application Figure 1 The energy storage monitoring method is applied to the energy storage monitoring module in the above energy storage monitoring system, such as Figure 3 As shown, the energy storage monitoring method provided in the embodiment of the present application includes:

[0073] S301. Receive temperatures sent by multiple temperature monitoring modules.

[0074] In this embodiment, the temperature of the energy storage element sent by multiple temperature monitoring modules is received in real time to achieve temperature anomaly monitoring during the operation of the energy storage element.

[0075] S302, analyzing the temperature and the preset temperature threshold to obtain an analysis result, and controlling the semiconductor heat dissipation element and the energy storage element in sequence according to the analysis result.

[0076] In this embodiment, the temperature is compared and analyzed with a preset temperature threshold, and the analysis process includes determining whether the temperature is higher, lower, or equal to the preset temperature threshold. According to the analysis result, the semiconductor heat dissipation element is controlled to control the energy storage element to achieve heat dissipation of the energy storage element. If the heat dissipation of the energy storage element does not work, the energy storage element is controlled.

[0077] In the energy storage monitoring method provided in the embodiment of the present application, the energy storage monitoring module receives temperature information from multiple temperature monitoring modules and compares and analyzes these temperatures with pre-set temperature thresholds to achieve precise temperature control. According to the analysis results, the semiconductor heat dissipation element and the energy storage element are controlled in turn to ensure that the energy storage element works within the appropriate temperature range, avoid safety hazards caused by abnormal temperature of the energy storage module, and improve the stability of the entire system.

[0078] Figure 4 A schematic diagram of a method for monitoring energy storage provided in an embodiment of the present application Figure 2 , this embodiment is in Figure 3 Based on the embodiment, a possible implementation method of the energy storage monitoring method is described in detail. Figure 4 As shown, the energy storage monitoring method provided in the embodiment of the present application includes:

[0079] S401. Receive temperatures sent by multiple temperature monitoring modules.

[0080] Step S401 is similar to step S301 and will not be described in detail here.

[0081] S402: Determine whether the temperature reaches a first preset temperature threshold.

[0082] S403: If not, then the control of the semiconductor heat dissipation element is not started.

[0083] S404: If yes, calculate the difference between the temperature and the first preset temperature threshold, and adjust the intensity of the semiconductor heat dissipation element's heat dissipation for the energy storage element according to the difference.

[0084] In this embodiment, it is determined whether the temperature reaches the first preset temperature threshold. If the temperature does not reach the first preset temperature threshold, the operation of starting to control the semiconductor heat dissipation element is not taken. If the temperature reaches the first preset temperature threshold, the difference between the temperature and the first preset temperature threshold is calculated, and the working intensity of the semiconductor heat dissipation element to dissipate heat for the energy storage element is adjusted accordingly according to the size of the difference.

[0085] For example, if the difference is large, the semiconductor heat dissipation element is controlled to increase its working intensity to dissipate heat from the energy storage element more quickly and powerfully; if the difference is small, the working intensity is appropriately adjusted to achieve a more precise and appropriate heat dissipation effect.

[0086] S405: When the temperature of the energy storage element does not drop, determine whether the current temperature of the energy storage element reaches a second preset temperature threshold.

[0087] S406: If yes, control the energy storage element to be disconnected from the external power supply device; if no, execute step S404.

[0088] In this embodiment, after the semiconductor heat dissipation element dissipates heat for the energy storage element, the temperature of the energy storage element does not drop, but continues to rise, then it is further determined whether the current temperature of the energy storage element reaches the second preset temperature threshold. If the second preset temperature threshold is reached, in order to prevent the temperature from overheating and causing damage to a single energy storage element or damage to peripheral equipment, the energy storage element is controlled to be disconnected from the external power supply device to avoid further temperature increases and more serious consequences. If the second preset temperature threshold has not been reached, step S404 is continued, and the working intensity of the semiconductor heat dissipation element is adjusted according to the temperature conditions to further dissipate heat for the energy storage element so that its temperature can drop or remain within a safe range.

[0089] An energy storage monitoring method provided in an embodiment of the present application receives temperature data from multiple temperature monitoring modules; determines whether the temperature reaches a first preset temperature threshold, and if so, calculates the difference between the temperature and the first preset temperature threshold, and adjusts the intensity of heat dissipation of the semiconductor heat dissipation element to the energy storage element according to the difference; if the temperature of the energy storage element does not drop after heat dissipation, then determines whether the current temperature reaches a second preset temperature threshold. If so, the energy storage element is controlled to be disconnected from the external power supply device. Therefore, the method ensures that the energy storage element operates within a suitable temperature range by timely and effective monitoring of temperature changes; and improves the heat dissipation efficiency and accuracy by finely controlling the semiconductor heat dissipation element, avoiding damage to it due to excessive temperature. Moreover, when the temperature is too high, the energy storage element can be disconnected from the external power supply device in a timely manner, effectively preventing possible dangerous situations and ensuring the safe and stable operation of the entire system.
