Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to an emergency power supply device. Background Technology

[0002] The safe and stable operation of modern power systems is directly related to public safety, economic development, and people's livelihood. To prevent power grid collapse in the event of a large-scale power outage and to ensure rapid restoration of power supply, emergency power supply devices have become indispensable key equipment in modern power systems.

[0003] Because emergency power supply devices are typically exposed to the natural environment, the performance and lifespan of their key components are significantly affected by ambient temperature. In extremely cold environments, the internal resistance of the energy storage components in emergency power supply devices increases dramatically, resulting in a significant decrease in usable capacity. This can easily lead to insufficient instantaneous discharge capacity, making it impossible to reliably start the power generation components and causing a loss of emergency power supply function. In extremely hot environments, the internal components of emergency power supply devices age faster, their electrical performance degrades, leading to a decrease in overall reliability and a higher susceptibility to failure. Summary of the Invention

[0004] Therefore, it is necessary to provide an emergency power supply device to address the issue of environmental temperature affecting emergency power supply devices.

[0005] This invention provides an emergency power supply device, comprising: Power supply mechanism; A heat preservation mechanism includes a housing and a temperature regulating component. The housing has a receiving cavity, and the power supply mechanism is disposed in the receiving cavity. At least a portion of the temperature regulating component is disposed in the receiving cavity, and the temperature regulating component is used to regulate the temperature in the receiving cavity.

[0006] In one embodiment, the temperature control assembly includes a temperature controller, an input pipe, an output pipe, and a temperature control layer. The temperature control layer is disposed within the receiving cavity and has a temperature control channel. The temperature controller is installed in the housing. The input pipe includes a first port and a second port. The first port is connected to the temperature controller, and the second port is connected to the temperature control channel. The output pipe has a third port and a fourth port. The third port is connected to the temperature controller, and the fourth port is connected to the temperature control channel, so that the temperature controller, the input pipe, the output pipe, and the temperature control layer form a loop for the circulation of the temperature control medium.

[0007] In one embodiment, the temperature regulating layer includes multiple layers, which are spaced apart within the receiving cavity. The input pipe has multiple second ports, which are connected to the temperature regulating layers one by one. The output pipe has multiple fourth ports, which are connected to the temperature regulating layers one by one.

[0008] In one embodiment, the temperature regulating layer is formed by an insulated pipe, which includes a first sub-pipe and a second sub-pipe. The first sub-pipe is sleeved on the outside of the second sub-pipe, and the temperature regulating channel is disposed inside the second sub-pipe. The gap between the inner wall of the first sub-pipe and the outer wall of the second sub-pipe is filled with an insulating agent.

[0009] In one embodiment, the second sub-pipe has an input port and an output port, the input port is connected to the second port, the output port is connected to the fourth port, and the diameter of the input port is smaller than the diameter of the output port.

[0010] In one embodiment, the insulation mechanism further includes an environmental monitoring component, which is installed in the housing and electrically connected to the temperature control component.

[0011] In one embodiment, the environmental monitoring component includes a first temperature sensor, a second temperature sensor, and a constant temperature maintenance module. The first temperature sensor is disposed on the outer wall of the housing, and the second temperature sensor is disposed on the inner wall of the receiving cavity. The first temperature sensor, the second temperature sensor, and the temperature control component are all electrically connected to the constant temperature maintenance module.

[0012] In one embodiment, the environmental monitoring component further includes a wind speed sensor mounted on the top of the housing and electrically connected to the constant temperature maintenance module.

[0013] In one embodiment, the power supply mechanism includes a power generation component, an energy storage component, a control component, a switching component, and a power distribution component. The power generation component and the energy storage component are both electrically connected to the control component. The input terminal of the switching component is electrically connected to the power generation component, the energy storage component, and the main power grid. The output terminal of the switching component is electrically connected to the input terminal of the power distribution component, and the output terminal of the power distribution component is electrically connected to the load.

[0014] In one embodiment, the insulation mechanism is electrically connected to the energy storage component so that the insulation mechanism can obtain electrical energy through the energy storage component.

[0015] The aforementioned emergency power supply device houses the power supply mechanism for providing emergency power within a cabinet-like enclosure. A temperature-regulating component is installed within the enclosure to actively adjust the temperature within the enclosure, maintaining it stably in a preset constant-temperature standby state. This ensures the power supply mechanism operates within its optimal temperature range, preventing issues like insufficient instantaneous discharge capacity and unreliable startup caused by increased internal resistance and a sudden drop in available capacity in extremely cold environments. Conversely, it slows down the aging rate of internal components in extremely hot environments, preventing electrical performance degradation. This ensures the power supply mechanism maintains excellent discharge characteristics under various extreme climatic conditions, significantly improving the startup reliability, response speed, and long-term operational stability of the emergency power supply device during sudden power outages. It effectively addresses the issue of power supply mechanism performance degradation preventing rated energy output in emergency situations, ensuring the stability and reliability of emergency power supply. This provides solid support for power grid restoration after large-scale power outages and effectively enhances the disaster resilience and operational safety of the power system.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] See Figure 1 The diagram shows a structural schematic of an emergency power supply device according to an embodiment of this application. The emergency power supply device includes a power supply mechanism and a heat preservation mechanism 10. The power supply mechanism is used to provide emergency power.

[0029] The insulation mechanism 10 includes a housing 100 and a temperature regulating component 200. The housing 100 has a receiving cavity 110, and a power supply mechanism is disposed in the receiving cavity 110. At least a portion of the temperature regulating component 200 is disposed in the receiving cavity 110, and the temperature regulating component 200 is used to regulate the temperature in the receiving cavity 110. Specifically, the housing 100 is an insulation housing.

[0030] The emergency power supply device described in this application embodiment houses the power supply mechanism for providing emergency power within the receiving cavity 110 of the housing 100, which is equipped with a heat preservation mechanism 10. A temperature regulating component 200 is installed in the housing 100 to actively regulate the temperature inside the receiving cavity 110, thereby stably maintaining the receiving cavity 110 in a preset constant temperature standby state. This ensures that the core components of the power supply mechanism are always in a suitable constant temperature environment, allowing the power supply mechanism to operate within the optimal temperature range and effectively preventing the emergency power supply device from being affected by extreme ambient temperatures.

[0031] The emergency power supply device described in this application embodiment can avoid the problems of insufficient instantaneous discharge capacity and inability to start reliably caused by increased internal resistance and sudden drop in available capacity of the power supply mechanism in extremely cold environments. At the same time, it can slow down the aging rate of internal components of the power supply mechanism in extremely hot environments, avoid electrical performance degradation, and ensure that the power supply mechanism can maintain excellent discharge characteristics under various extreme climatic conditions. It significantly improves the starting reliability, response speed and long-term operational stability of the emergency power supply device when the power grid suddenly fails. It can effectively solve the problem of the inability to output rated energy under emergency conditions caused by the performance degradation of the power supply mechanism, effectively ensure the stability and reliability of emergency power supply, provide solid support for the power grid power restoration after large-scale power outages, and effectively improve the disaster resistance resilience and operational safety level of the power system.

[0032] In one exemplary embodiment, such as Figure 1 As shown, the enclosure 100 has an opening 120, and a sealing door 130 is provided at the opening 120. By providing an opening 120 on the enclosure 100 and a sealing door 130 at the opening 120, a convenient operating channel is provided through the opening 120 for the installation, inspection, maintenance, and replacement of components such as the power supply mechanism inside the enclosure 100, greatly improving the assembly and maintenance efficiency of the device. On the other hand, when the sealing door 130 is closed, it can effectively seal the receiving cavity 110, isolating it from extreme high and low temperature environments. Combined with the temperature regulating component 200 and the insulation structure, it enhances the thermal insulation performance of the enclosure 100, ensuring the stability of the constant temperature control of the receiving cavity 110.

[0033] In an optional embodiment, the power supply mechanism includes a power generation component, an energy storage component, a control component, a switching component, and a distribution component. The power generation component and the energy storage component are both electrically connected to the control component. The input terminal of the switching component is electrically connected to the power generation component, the energy storage component, and the main power grid. The output terminal of the switching component is electrically connected to the input terminal of the distribution component, and the output terminal of the distribution component is electrically connected to the load. The power generation component is used to start and supply power when the main power grid fails. The energy storage component is electrically connected to the power generation component and is used to provide instantaneous power during a power outage and to switch to standby mode after the power generation component resumes operation. The control component is communicatively connected to both the power generation component and the energy storage component to monitor the grid status and coordinate the operation of each component. The switching component is connected between the main power grid, the power generation component, and the energy storage component to achieve automatic switching of the power supply path. The distribution component is connected to the output terminal of the switching component and is used to distribute power to the load.

[0034] In this embodiment, the control component continuously monitors the status of the main power grid. When the main power grid is normal, the emergency power supply device is in standby mode. Once the main power grid fails, the control component issues a command, and the switching component quickly disconnects the power supply path from the main power grid. At the same time, the energy storage component responds to the command of the control component and releases the stored electrical energy first. It provides instantaneous power support to the critical load through the power distribution component, ensuring that the load is not powered and providing energy for the start-up of the power generation component. The control component then starts the power generation component. After the power generation component starts successfully and operates stably, the control component coordinates the switching component to smoothly switch the main power supply to the power generation component. At this time, the energy storage component can switch to standby mode or be charged by the power generation component.

[0035] In one optional embodiment, because the energy storage components are in a float-charge standby state for extended periods, the lack of an effective charge-discharge cycle management mechanism can easily lead to problems such as sulfidation and capacity decay, resulting in performance degradation. Consequently, in the event of a sudden power outage and the need for emergency power supply, the components cannot provide rated energy output, making it difficult to guarantee the stability and reliability of emergency power supply and limiting the application effectiveness of the emergency power supply device. To address these issues, the insulation mechanism 10 is electrically connected to the energy storage components, enabling the insulation mechanism 10 to obtain electrical energy through the energy storage components. Exemplarily, multiple energy storage components are provided.

[0036] In this embodiment, the control component periodically activates the insulation mechanism 10 to regulate the temperature, causing the insulation mechanism 10 to actively and sequentially consume the electrical energy of each energy storage module, thereby triggering the periodic discharge of the energy storage modules. After the energy storage modules have finished discharging, the control component controls the main grid to charge the energy storage modules, thus realizing the periodic charge-discharge cycle of the energy storage modules.

[0037] Specifically, the operating power of the insulation mechanism 10 is directly obtained from the energy storage components, which are configured as multiple battery packs. The control component periodically and actively activates the insulation mechanism 10 to perform a temperature regulation cycle. For example, when the external temperature is suitable, it will periodically activate the regulating chamber 110 to adjust to the optimal range. When the external temperature is not suitable, it will automatically activate the regulating chamber 110 to adjust to the optimal range. This process consumes a small amount of power. The control component is designed to use different energy storage components sequentially and in turn to provide this energy. When one energy storage component is discharged to a preset low charge state, the power of the next energy storage component is used. At this time, the control component controls the emergency power supply device to switch to the main grid power supply state to charge the low-charge energy storage component and restore it to a fully charged state. This cycle is repeated for all energy storage components. Through this periodic, low-power active power consumption behavior, the necessary periodic charge and discharge cycle of the energy storage components is triggered, effectively preventing problems such as sulfation and capacity decay caused by long-term float charging of the batteries. This maintains the health and actual usable capacity of the energy storage components and helps to extend their service life.

[0038] Combination Figure 2 and Figure 3 The diagram shows a schematic of the specific structure of an emergency power supply device according to one embodiment of this application. In some embodiments, the temperature control component 200 includes a temperature controller 210, an input pipe 220, an output pipe 230, and a temperature control layer 240. The temperature control layer 240 is disposed in the receiving cavity 110 and has a temperature control channel 241. The temperature controller 210 is installed in the housing 100. The input pipe 220 includes a first port 221 and a second port 222. The first port 221 is connected to the temperature controller 210, and the second port 222 is connected to the temperature control channel 241. The output pipe 230 has a third port 231 and a fourth port 232. The third port 231 is connected to the temperature controller 210, and the fourth port 232 is connected to the temperature control channel 241, so that the temperature controller 210, the input pipe 220, the output pipe 230, and the temperature control layer 240 form a loop for the circulation of the temperature control medium. For example, the thermostat 210, the input pipe 220 and the output pipe 230 are all installed on the outer side wall of the enclosure 100, and the input pipe 220 and the output pipe 230 are both connected to the temperature regulating layer 240 through the side wall of the enclosure 100.

[0039] In this embodiment, a temperature controller 210, an input pipe 220, an output pipe 230, and a temperature regulating layer 240 with a temperature regulating channel 241 are configured. The temperature regulating layer 240 is arranged inside the receiving cavity 110 of the housing 100. The two ends of the input pipe 220 are connected to the temperature controller 210 and the temperature regulating channel 241, respectively. The two ends of the output pipe 230 are also connected to the temperature controller 210 and the temperature regulating channel 241, so that the temperature controller 210, the input pipe 220, the temperature regulating channel 241, and the output pipe 230 together form a temperature regulating system. The closed-loop circulation of the temperature-regulating medium, relying on the temperature controller 210 to precisely control the temperature of the temperature-regulating medium entering the temperature-regulating layer 240, achieves efficient, uniform, and precise constant temperature control inside the containment cavity 110. This enables rapid adjustment and long-term stable maintenance of the internal temperature of the containment cavity 110, ensuring that the containment cavity 110 is stably in a preset constant temperature standby state. This keeps the power supply mechanism always operating within the optimal temperature range, improving the start-up reliability, response speed, and long service life of the emergency power supply device in the event of a sudden power outage.

[0040] In one exemplary embodiment, the thermostat 210 integrates a PID precision temperature control algorithm, and the temperature control accuracy can meet the constant temperature control requirements of 20℃±5℃ within the cavity 110. The thermostat 210 includes a bidirectional control module for both cooling and heating and a built-in circulating pump group, which can simultaneously drive the refrigeration unit and the heating unit, adapting to the bidirectional temperature regulation requirements of heating in extremely cold environments or cooling in extremely hot environments. The built-in circulating pump group provides power for the closed-loop flow of the temperature regulating medium, eliminating the need for additional power components and simplifying the system structure.

[0041] In one exemplary embodiment, the temperature-regulating medium is a synthetic insulating thermally conductive oil or an ethylene glycol-deionized water-based thermally conductive antifreeze.

[0042] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the temperature-regulating layer 240 includes multiple layers, which are spaced apart within the receiving cavity 110. The input pipe 220 has multiple second ports 222, each connected to a temperature-regulating layer 240 in a corresponding manner. The output pipe 230 has multiple fourth ports 232, each connected to a temperature-regulating layer 240 in a corresponding manner. Specifically, the multiple temperature-regulating layers 240 are arranged in a linear array within the receiving cavity 110.

[0043] This embodiment uses multiple temperature-regulating layers 240 spaced apart within the housing cavity 110 of the enclosure 100. The input pipe 220 has multiple second ports 222 corresponding to the temperature-regulating layers 240, and the output pipe 230 has multiple fourth ports 232 corresponding to the temperature-regulating layers 240. This allows the temperature controller 210 to synchronously deliver the temperature-regulating medium to each independent temperature-regulating layer 240 via the input pipe 220, and then return via the output pipe 230 to form a multi-parallel closed-loop temperature regulation circuit. This significantly improves the uniformity and synchronicity of temperature regulation within the housing cavity 110. The multi-point distributed temperature regulation structure achieves constant temperature control throughout the housing cavity 110 without dead zones, avoiding the problems of excessive local temperature differences and delayed temperature regulation response that are common in single-path temperature regulation structures. This further enhances the startup reliability, response speed, and long-term operational stability of the emergency power supply device during sudden large-scale power outages.

[0044] In one exemplary embodiment, such as Figure 2 and Figure 3 As shown, the input pipe 220 is provided with multiple first branches, and each second port 222 is provided on the first branch in a one-to-one correspondence. The output pipe 230 is provided with multiple second branches, and each fourth port 232 is provided on the second branch in a one-to-one correspondence.

[0045] In an optional embodiment, such as Figure 4 , Figure 5 and Figure 6 As shown, the temperature-regulating layer 240 is formed by an insulated pipe, which includes a first sub-pipe 242 and a second sub-pipe 243. The first sub-pipe 242 is sleeved on the outside of the second sub-pipe 243, and a temperature-regulating channel 241 is disposed inside the second sub-pipe 243. The gap between the inner wall of the first sub-pipe 242 and the outer wall of the second sub-pipe 243 is filled with an insulating agent 244. Specifically, the temperature-regulating layer 240 is formed by repeatedly bending the insulated pipe.

[0046] In this embodiment, the insulated pipe is bent back and forth to form a temperature regulating layer 240. At the same time, the insulated pipe is configured as a double-layer sleeve structure in which the first sub-pipe 242 is sleeved on the outside of the second sub-pipe 243. The temperature regulating channel is located inside the second sub-pipe 243, and the gap between the inner wall of the first sub-pipe 242 and the outer wall of the second sub-pipe 243 is filled with heat-insulating agent 244. The back and forth pipe arrangement can significantly extend the flow path and heat exchange time of the temperature regulating medium in the temperature regulating layer 240, expand the heat exchange area between the temperature regulating layer 240 and the internal environment of the receiving cavity 110, significantly improve the heat exchange efficiency and temperature regulation uniformity, and ensure the accuracy and stability of constant temperature control in the receiving cavity 110.

[0047] On the other hand, the structural design of filling the gap between the first sub-pipe 242 and the second sub-pipe 243 in this embodiment with thermal insulation agent 244, with the phase change temperature point of the thermal insulation agent 244 set within a preset constant temperature threshold range, means that when the temperature of the receiving cavity 110 fluctuates slightly, the temperature of the temperature regulating medium flowing through it will also change. If the temperature is slightly higher than the phase change point, the thermal insulation agent 244 absorbs heat and melts, preventing the temperature from rising rapidly. If the temperature is slightly lower than the phase change point, the thermal insulation agent 244 releases heat and solidifies, preventing the temperature from falling rapidly. The thermal insulation agent 244 utilizes its large latent heat of phase change to provide a huge thermal inertia buffer for the receiving cavity 110, thereby avoiding internal temperature fluctuations caused by short-term external temperature fluctuations, brief heating of internal equipment, or lag in control system regulation. This makes the temperature distribution of the receiving cavity 110 more uniform and stable, reduces the operating frequency of the temperature controller 210, and improves the constant temperature quality and operational stability.

[0048] In one exemplary embodiment, the insulating agent 244 is a phase change thermal storage material (PCM).

[0049] In an optional embodiment, such as Figure 5 and Figure 6 As shown, the second sub-pipe 243 has an inlet 2431 and an outlet 2432. The inlet 2431 is connected to the second port 222, and the outlet 2432 is connected to the fourth port 232. The diameter of the inlet 2431 is smaller than the diameter of the outlet 2432. The diameter of the first sub-pipe 242 remains unchanged.

[0050] In this embodiment, an inlet 2431 and an outlet 2432 are respectively set at both ends of the second sub-pipe 243. The diameter of the inlet 2431 is set to be smaller than that of the outlet 2432. This makes the diameter of the inlet 2431 smaller, resulting in a thicker layer of the insulating agent 244 at the inlet 2431 end. This allows the temperature-regulating medium to be isolated by the insulating agent 244 when the temperature is high, preventing sufficient heat exchange. On the one hand, this avoids heat exchange at the inlet 2431 end, which could lead to higher temperatures in some parts of the cavity 110. On the other hand, the gradually expanding flow cross-section allows the temperature-regulating medium to retain some heat as it flows with the first sub-pipe 242. As it flows towards the outlet 2432, the insulating agent 244 gradually thins, reducing the obstruction to heat exchange of the temperature-regulating medium. This allows the heat to dissipate fully, which is beneficial for temperature uniformity inside the cavity 110 and improves the efficiency and temperature uniformity of the entire heat exchange process.

[0051] In one exemplary embodiment, such as Figure 5 and Figure 6 As shown, the diameter of the output port 2432 is set to twice the diameter of the input port 2431, which can improve the heat exchange efficiency and temperature regulation uniformity of the temperature control layer 240.

[0052] In an optional embodiment, such as Figure 1 As shown, the insulation mechanism 10 also includes an environmental monitoring component 300, which is installed in the housing 100 and is electrically connected to the temperature control component 200.

[0053] In this embodiment, by installing an environmental monitoring component 300 in the enclosure 100 and electrically connecting the environmental monitoring component 300 to the temperature control component 200, key parameters such as the ambient temperature inside and outside the enclosure 100 can be collected by the environmental monitoring component 300. The collected data is then synchronously fed back to the temperature controller 210 of the temperature control component 200, realizing closed-loop intelligent control of the temperature control component 200. The temperature controller 210 can dynamically adjust the temperature, circulation flow rate and operating mode of the temperature control medium according to the detection data, which greatly improves the response speed and temperature control accuracy of the constant temperature control of the containment cavity 110, ensuring that the containment cavity 110 is maintained stably in the preset constant temperature standby range for a long time, and effectively avoiding abnormal chamber temperature caused by extreme external ambient temperature fluctuations or changes in operating conditions.

[0054] In an optional embodiment, such as Figure 2 and Figure 3As shown, the environmental monitoring component 300 includes a first temperature sensor 310, a second temperature sensor 320, and a constant temperature maintenance module. The first temperature sensor 310 is disposed on the outer wall of the housing 100, and the second temperature sensor 320 is disposed on the inner wall of the receiving cavity 110. The first temperature sensor 310, the second temperature sensor 320, and the temperature control component 200 are all electrically connected to the constant temperature maintenance module.

[0055] In this embodiment, the first temperature sensor 310 collects the ambient temperature data outside the enclosure 100, and the second temperature sensor 320 accurately collects the working temperature inside the cavity 110, providing precise data support for constant temperature control from both the external environment and the internal working conditions. At the same time, relying on the constant temperature maintenance module, combined with the temperature difference between the inside and outside and the temperature change trend, it accurately calculates and outputs the appropriate temperature adjustment command to the temperature controller 210 of the temperature control component 200. This realizes the upgrade of the insulation mechanism 10 from passive constant temperature control to active feedforward intelligent control. It can dynamically adjust the output temperature of the temperature controller 210 in advance according to the extreme temperature changes in the outside, greatly improving the response speed, temperature control accuracy and anti-environment interference capability of the constant temperature control of the cavity, and stably maintaining the cavity 110 in the preset constant temperature standby state.

[0056] In one exemplary embodiment, such as Figure 2 and Figure 3 As shown, multiple first temperature sensors 310 and second temperature sensors 320 are provided to improve the detection accuracy of the first temperature sensor 310 and the second temperature sensor 320.

[0057] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the environmental monitoring component 300 also includes a wind speed sensor 330, which is mounted on the top of the housing 100 and is electrically connected to the constant temperature maintenance module. The wind speed sensor 330 is used to detect airflow speed.

[0058] In this embodiment, the wind speed sensor 330 accurately detects the airflow speed of the external environment of the enclosure 100, providing key operational data on the environmental wind speed dimension for the intelligent control of the constant temperature maintenance module. Combined with the external environmental temperature data collected by the first temperature sensor 310, it enables accurate prediction and quantitative evaluation of the heat exchange intensity between the external environment and the containment cavity 110, and dynamically adjusts the output parameters of the temperature controller 210 accordingly, thereby improving the accuracy, stability and anti-interference capability of the constant temperature control of the containment cavity 110.

[0059] In an exemplary embodiment, when the first temperature sensor 310 detects a low external temperature and the wind speed sensor 330 detects a high airflow speed, the thermostat 210 increases the initial temperature of the input heat or decreases the initial temperature of the input cold energy to accurately compensate for the additional heat loss caused by the acceleration of the ambient airflow and prevent abnormal temperature drops inside the containment cavity 110. When the first temperature sensor 310 detects a high external temperature and the wind speed sensor 330 detects a slow airflow speed, the thermostat 210 decreases the initial temperature of the input heat or increases the initial temperature of the input cold energy. This effectively improves temperature regulation efficiency while avoiding overshoot in the temperature regulation of the containment cavity 110. The thermostat 210 not only relies on internal and external temperature data for constant temperature control but also achieves feedforward precise dynamic regulation based on dual-dimensional parameters of ambient temperature and airflow speed. This significantly improves the adaptability of the temperature control system to complex, variable, and extreme outdoor environments and further enhances the accuracy, stability, and anti-interference capability of the constant temperature control of the containment cavity.

[0060] In one exemplary embodiment, the control component is further configured to monitor and record the voltage-current curve of the energy storage component during each charge-discharge cycle to calculate the current actual capacity of the energy storage component. The calculated actual capacity of the energy storage component is compared with a preset capacity threshold. When the actual capacity is lower than the capacity threshold, an alarm signal is generated and issued to remind personnel to check or replace the corresponding energy storage component.

[0061] Specifically, the control component monitors and records the changes in voltage and current of each energy storage component during its discharge phase, thereby plotting a discharge curve and calculating the current actual capacity of the energy storage component. The control component compares this actual capacity with a preset safe capacity threshold, such as 80% of the rated capacity. If the actual capacity of an energy storage component remains below the threshold, the control component will issue warning signals in the form of sound and light, or remote communication, to prompt staff to replace or maintain the energy storage component. This achieves online automatic diagnosis of the health status of the energy storage components, eliminating the need for regular manual inspections and allowing the control component to monitor the performance degradation of each energy storage component. This early warning enables maintenance personnel to intervene before the energy storage components completely fail, avoiding the risk of the entire emergency power supply device failing due to the failure of a single energy storage component in an emergency, and improving the overall reliability of the emergency power supply device.

[0062] In one exemplary embodiment, the control component is also configured to acquire a meteorological data source to receive weather forecast information for a future period. Specifically, the meteorological data source includes, but is not limited to, predicted temperature and wind speed.

[0063] The control component in this embodiment is based on meteorological data sources and controls the working parameters of the insulation mechanism 10 in advance to perform predictive temperature control, so as to reduce the impact of sudden environmental changes on the constant temperature state inside the containment cavity 110 and further optimize energy efficiency.

[0064] Furthermore, the control component connects to a meteorological data source via a communication module to obtain weather forecast information for the next 24-48 hours, particularly predicted temperature and wind speed data. Based on this forecast information, the constant temperature maintenance module and the control component can execute predictive temperature control strategies. For example, if the forecast indicates a significant drop in temperature accompanied by strong winds at night, the control component can appropriately increase the maintenance temperature of the insulation mechanism 10 in advance or start a higher-power preheating mode in advance to store heat and resist the impending severe heat loss, thereby smoothing temperature fluctuations, reducing the internal temperature deviation of the containment cavity 110, and upgrading passive response control to active predictive control. This allows the emergency power supply device to respond to drastic changes in the external environment in advance, significantly reducing the impact of sudden environmental changes on the internal constant temperature state, making temperature control more stable. At the same time, predictive control can optimize energy dispatch, avoiding the need to take more drastic and energy-intensive compensation measures during sudden environmental changes, further improving energy efficiency.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
