Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy storage systems, in particular to a dehumidification control method and device for an energy storage system and the energy storage system. BACKGROUND

[0002] The existing humidity control method for the energy storage system is to control and adjust the temperature of the energy storage system by a dehumidifier mainly composed of a dehumidification air conditioner, or to control condensation by setting a thermal insulation coating at the bottom of the liquid cooling plate of the thermal management system. The opening condition of the dehumidifier is usually based on the surface humidity of the liquid cooling plate, or the humidity data is detected by a humidity sensor to determine the opening condition. However, the influence of the saturation of the anti-condensation coating is not considered, and the situation that the heat resistance decreases and the surface temperature rises after the coating is oversaturated, and the risk of condensation increases, may occur. Moreover, the humidity control method is based on the actual humidity and the determination of the fixed humidity threshold for control, which cannot adapt to the dynamic changes of the environment, and affects the dehumidification effect and energy consumption. SUMMARY

[0003] Therefore, the present application provides a dehumidification control method and device for an energy storage system and the energy storage system to solve the problem that the existing humidity control method cannot adapt to the dynamic changes of the environment, affecting the dehumidification effect and energy consumption.

[0004] In a first aspect, the present application provides a dehumidification control method for an energy storage system, which comprises: obtaining the saturation of the anti-condensation coating and the relative humidity of the environment of the current energy storage system; determining the power adjustment weight based on the first difference between the saturation of the anti-condensation coating and the target coating saturation, and the second difference between the relative humidity of the environment and the target relative humidity; adjusting the rated power based on the power adjustment weight to obtain the target dehumidification power; and controlling the dehumidification device to operate based on the target dehumidification power to dehumidify the energy storage system.

[0005] The dehumidification control method for the energy storage system provided in the present embodiment obtains the saturation of the anti-condensation coating and the relative humidity of the environment of the current energy storage system, determines the power adjustment weight based on the first difference between the saturation of the anti-condensation coating and the target coating saturation, and the second difference between the relative humidity of the environment and the target relative humidity, adjusts the rated power based on the power adjustment weight to obtain the target dehumidification power, and finally controls the dehumidification device to dehumidify the energy storage system based on the target dehumidification power. By combining the environmental humidity and the saturation of the anti-condensation coating, the dehumidification amount demand is dynamically adjusted according to the real-time heat resistance of the coating and the environmental humidity, the dehumidification device is controlled to dehumidify the energy storage system based on the dehumidification amount demand, a linear compensation power regulation mode is formed, the dynamic changes of the environment are adapted, and both the dehumidification effect and the energy consumption can be ensured.

[0006] In an optional implementation, before determining the power adjustment weight based on a first difference between the anti-condensation coating saturation and the target coating saturation, and a second difference between the ambient relative humidity and the target relative humidity, the method further includes: determining whether the anti-condensation coating saturation is within a first preset saturation range; if the anti-condensation coating saturation is within the first preset saturation range, determining whether the ambient relative humidity is greater than a first preset humidity threshold; if the ambient relative humidity is greater than the first preset humidity threshold, performing the step of determining the power adjustment weight based on the first difference between the anti-condensation coating saturation and the target coating saturation, and the second difference between the ambient relative humidity and the target relative humidity.

[0007] Based on the relationship between the actual anti-condensation coating saturation and the first saturation range, and the relationship between the actual ambient relative humidity and the first humidity threshold, this invention formulates dehumidifier power start / stop and operation strategies corresponding to different coating saturations and ambient relative humidity, so as to achieve precise matching of the dehumidification needs of the energy storage system and avoid over-control or under-control.

[0008] In an optional embodiment, the method further includes: if the saturation of the anti-condensation coating is greater than a first saturation threshold, determining the target dehumidification power as the maximum dehumidification power of the dehumidification device, wherein the first saturation threshold is the maximum saturation value of the first preset saturation range.

[0009] If the current saturation of the anti-condensation coating is greater than the first saturation threshold, the present invention can first control the dehumidification device to reduce the saturation of the anti-condensation coating to a safe saturation range, thereby prioritizing the resolution of coating saturation risk, avoiding delays in controlling the high saturation of the coating, which could lead to a further escalation of condensation risk, and reducing the difficulty of subsequent humidity control.

[0010] In one optional implementation, determining the power adjustment weight based on a first difference between the anti-condensation coating saturation and the target coating saturation, and a second difference between the ambient relative humidity and the target relative humidity, includes: dividing the first difference by the target coating saturation to obtain a saturation deviation; dividing the second difference by the target relative humidity to obtain a humidity deviation; multiplying the saturation deviation by a corresponding first preset weighting coefficient to obtain a first weighted deviation; multiplying the humidity deviation by a corresponding second preset weighting coefficient to obtain a second weighted deviation; and adding the first weighted deviation, the second weighted deviation, and a preset benchmark weighting factor to obtain the power adjustment weight.

[0011] This invention eliminates deviations and misjudgments caused by differences in target values ​​through difference normalization, ensuring the stability of dehumidification control. Furthermore, the designed weighting coefficient is related to the degree of influence of environmental factors, enabling precise control in specific scenarios.

[0012] In one optional implementation, the second preset weight coefficient is obtained through the following steps: determining whether the relative humidity of the environment is greater than a second preset humidity threshold, wherein the second preset humidity threshold is greater than the first preset humidity threshold; if the relative humidity of the environment is greater than the second preset humidity threshold, setting a first weight value as the second preset weight coefficient; if the relative humidity of the environment is not greater than the second preset humidity threshold, setting a second weight value as the second preset weight coefficient, wherein the second weight value is less than the first weight value.

[0013] This invention further refines the setting logic of weight coefficients for different humidity ranges, enabling the weight coefficients to be flexibly adjusted according to the ambient humidity, thereby improving the environmental adaptability of the weight coefficients. In an optional implementation, during the process of dehumidifying the energy storage system by controlling the operation of the dehumidification device based on the target dehumidification power, the method further includes: controlling the ventilation device to operate at a first wind speed setting; monitoring the rate of decrease in ambient relative humidity; and if the rate of decrease in ambient relative humidity is less than a first preset rate threshold, switching the ventilation device to operate at a second wind speed setting, wherein the wind speed of the second wind speed setting is greater than the wind speed of the first wind speed setting.

[0014] This invention uses multi-gradient ventilation-assisted control to not only improve the overall dehumidification effect of the energy storage system, but also reduce unnecessary energy consumption and ensure the stability of the environmental humidity of the energy storage system.

[0015] In an optional embodiment, the method further includes: when the saturation of the anti-condensation coating is detected to be less than a second saturation threshold and the relative humidity of the environment is less than a second preset humidity threshold, controlling the dehumidification device to switch to a closed state; the second saturation threshold is the minimum saturation value of the first preset saturation range, and the second preset humidity threshold is less than the first preset humidity threshold.

[0016] When the current ambient humidity of the energy storage system meets the requirements for normal operation, the present invention can shut down the dehumidification mode to save energy.

[0017] In an optional embodiment, the method further includes: after controlling the dehumidifier to switch to the off state, monitoring the dehumidifier to remain in the off state for a first duration; and when the first duration reaches a first preset duration threshold, switching the ventilation device to the off state.

[0018] This invention controls the ventilation device to utilize the waste heat from the dehumidification device to remove residual moisture, thereby improving the dehumidification effect of the energy storage system and ensuring the environmental stability of the energy storage system.

[0019] In an optional implementation, the method further includes: recording a second duration of operation of the dehumidifier during the operation of the dehumidifier; detecting the ambient relative humidity in real time and calculating the change in the ambient relative humidity; and controlling the dehumidifier to switch to a closed state when the second duration is greater than a second preset duration threshold and the change in the ambient relative humidity is less than a preset humidity change threshold, and sending a prompt message to the user indicating an abnormal dehumidification operation.

[0020] When dehumidification is determined to be ineffective, this invention can promptly terminate the operation of the dehumidification device to avoid energy waste, and provide the user with a prompt message indicating abnormal dehumidification operation, enabling the user to repair the dehumidification device in a timely manner, extending the service life of the dehumidification device, and ensuring the stable operation of the energy storage system.

[0021] In an optional embodiment, the method further includes: determining whether the saturation of the anti-condensation coating of the current energy storage system is less than a third coating saturation threshold; if the saturation of the anti-condensation coating of the current energy storage system is less than the third coating saturation threshold, controlling the coating execution device to perform an adding operation on the anti-condensation coating until the saturation of the anti-condensation coating of the current energy storage system is not less than the third coating saturation threshold.

[0022] When the current anti-condensation coating saturation is determined to be less than the third coating saturation, the present invention can prioritize the coating addition operation, and start the dehumidification control only after the standard is met, thereby reducing unnecessary energy consumption and equipment damage.

[0023] Secondly, the present invention provides a dehumidification control device for an energy storage system. The device includes a data acquisition module for acquiring the current saturation of the anti-condensation coating of the energy storage system and the ambient relative humidity; a weight adjustment module for determining a power adjustment weight based on a first difference between the anti-condensation coating saturation and the target coating saturation, and a second difference between the ambient relative humidity and the target relative humidity; a power adjustment module for adjusting the rated power based on the power adjustment weight to obtain a target dehumidification power; and a system dehumidification module for controlling the operation of the dehumidification device based on the target dehumidification power to dehumidify the energy storage system.

[0024] Thirdly, the present invention provides an energy storage system, the energy storage system including a dehumidification device and a controller, including: a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the computer instructions to perform the dehumidification control method of the energy storage system described in the first aspect or any corresponding embodiment.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] According to an embodiment of the present invention, a dehumidification control method for an energy storage system is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0029] This embodiment provides a dehumidification control method for an energy storage system, which can be used in the controller of the energy storage system. Figure 1 This is a flowchart of a dehumidification control method for an energy storage system according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps: Step S101: Obtain the saturation of the anti-condensation coating of the current energy storage system and the relative humidity of the environment.

[0030] In this embodiment of the invention, the relative humidity (RH) of the energy storage system can be obtained in real time through a humidity acquisition device, and the saturation (CS) of the anti-condensation coating of the energy storage system can be obtained in real time through a coating saturation detection device. The humidity acquisition device can be a temperature and humidity sensor array, which sends the collected relative humidity to the controller via wired or wireless means. The saturation of the anti-condensation coating can be collected based on a capacitive humidity sensor. As an example only, if the controller loses connection with the coating saturation detection device or the humidity acquisition device, the dehumidification device can be assumed to be in a closed state to avoid accidental operation.

[0031] After obtaining the data on the saturation of the anti-condensation coating and the relative humidity of the environment, the present invention can further preprocess the obtained data. The preprocessing operations include, but are not limited to, data filtering, which can effectively smooth out interference noise and reduce the impact of instantaneous fluctuations on the data; data calibration, which can ensure the accuracy and reliability of the data; and outlier removal, which can eliminate extreme data interference and avoid data misleading.

[0032] Step S102: Determine the power adjustment weight based on the first difference between the anti-condensation coating saturation and the target coating saturation, and the second difference between the ambient relative humidity and the target relative humidity.

[0033] This invention does not limit the method of determining the power adjustment weight based on the first difference and the second difference. For example, the first difference ΔCS between the saturation of the anti-condensation coating and the saturation of the target coating CStarget can be calculated, and the second difference ΔRH between the ambient relative humidity and the target relative humidity RHtarget can be calculated. Then, ΔCS can be converted into a dimensionless first influence weight (ΔCS is divided by the maximum allowable saturation deviation to obtain a standardized value), and ΔRH can be converted into a dimensionless second influence weight (ΔRH is divided by the maximum allowable humidity deviation to obtain a standardized value). Then, the first influence weight and the second influence weight can be added to obtain the power adjustment weight. This is only an example and is not limited.

[0034] Step S103: Adjust the rated power based on the power adjustment weight to obtain the target dehumidification power.

[0035] In this embodiment of the invention, the power adjustment weight can be multiplied by the rated power to obtain the target dehumidification power, wherein the rated power can be the default power value of the dehumidifier when there is no external interference or no adjustment.

[0036] Step S104: Control the operation of the dehumidification device based on the target dehumidification power to dehumidify the energy storage system.

[0037] The embodiments of the present invention can control the operation of the dehumidification device based on a determined target dehumidification power to dehumidify the energy storage system.

[0038] The dehumidification control method for the energy storage system provided in this embodiment obtains the current saturation of the anti-condensation coating of the energy storage system and the ambient relative humidity. Based on the first difference between the anti-condensation coating saturation and the target coating saturation, and the second difference between the ambient relative humidity and the target relative humidity, a power adjustment weight is determined. Then, the rated power is adjusted based on the power adjustment weight to obtain the target dehumidification power. Finally, the dehumidification device is controlled to dehumidify the energy storage system based on the target dehumidification power. By combining the ambient humidity and the anti-condensation coating saturation, the dehumidification demand is dynamically adjusted according to the real-time thermal resistance of the coating and the ambient humidity. The dehumidification device is controlled to dehumidify the energy storage system based on the dehumidification demand, forming a linear compensation power regulation mode. This achieves dynamic adaptation to environmental changes, ensuring both dehumidification effect and energy saving.

[0039] This embodiment provides a dehumidification control method for an energy storage system, which can be used in the controller of the energy storage system. Figure 2 This is a flowchart of a dehumidification control method for an energy storage system according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps: Step S201: Obtain the saturation of the anti-condensation coating and the ambient relative humidity of the current energy storage system. For details, please refer to [link to relevant documentation]. Figure 1 Step S101 of the illustrated embodiment will not be described again here.

[0040] Step S202: Determine whether the saturation of the anti-condensation coating is within the first preset saturation range; if the saturation of the anti-condensation coating is within the first preset saturation range, determine whether the relative humidity of the environment is greater than the first preset humidity threshold; if the relative humidity of the environment is greater than the first preset humidity threshold, determine the power adjustment weight based on the first difference between the saturation of the anti-condensation coating and the saturation of the target coating, and the second difference between the relative humidity of the environment and the target relative humidity.

[0041] In this embodiment of the invention, a first saturation range and a first humidity threshold are preset, for example, the first saturation range is [40%-75%] and the first humidity threshold is 80%. Setting the first saturation range indicates that the coating itself is in normal condition and still possesses anti-condensation capabilities, eliminating the need to initiate high-intensity (full-power) regulation due to coating issues, thus reducing ineffective intervention. The set humidity threshold serves as a humidity critical value, enabling timely triggering of regulation when the humidity approaches the critical value, preventing damage to the energy storage system from excessive ambient humidity. Furthermore, as shown in Table 1, this invention not only sets a start-up threshold but also a stop threshold, enabling immediate shutdown of the dehumidification device when the environment returns to the normal critical value, avoiding ineffective dehumidification and reducing unnecessary power consumption. This is only an example. For example, based on the relationship between the actual anti-condensation coating saturation and the first saturation range, and the relationship between the actual ambient relative humidity and the first humidity threshold, dehumidifier power start / stop and operation strategies corresponding to different coating saturations and ambient relative humidity can be formulated to achieve precise matching of the dehumidification needs of the energy storage system and avoid over-control or under-control. It can be determined whether the current anti-condensation coating saturation is within the first saturation range. If the current anti-condensation coating saturation is within the first saturation range, it can be determined whether the ambient relative humidity is greater than the first humidity threshold. If the ambient relative humidity is greater than the first humidity threshold, the power adjustment weight can be determined based on the first difference between the anti-condensation coating saturation and the target coating saturation, and the second difference between the ambient relative humidity and the target relative humidity.

[0042] In one optional implementation, if the saturation of the anti-condensation coating is greater than a first saturation threshold, the target dehumidification power is determined to be the maximum dehumidification power of the dehumidification device.

[0043] Wherein, the first saturation threshold is the maximum saturation value within the first preset saturation range.

[0044] This invention incorporates a priority adjustment mechanism for the anti-condensation coating saturation and ambient relative humidity, as shown in Table 1 below: Table 1

[0045] In this embodiment of the invention, before adjusting the dehumidification power of the dehumidification device based on the combination of the anti-condensation coating saturation and the ambient relative humidity, it is first determined whether the anti-condensation coating saturation is within the first saturation range. If the current anti-condensation coating saturation is greater than the first saturation threshold, the dehumidification device can be controlled to reduce the anti-condensation coating saturation to a safe saturation range. This prioritizes addressing the coating saturation risk, avoids delaying the control of high coating saturation, which could lead to a further escalation of the condensation risk, and reduces the difficulty of subsequent humidity control. At this time, the target dehumidification power can be determined as the maximum dehumidification power of the dehumidification device. The dehumidification device is then controlled to dehumidify the energy storage system at full power, promptly reducing the anti-condensation coating saturation to a safe range and ensuring the safe operation of the energy storage system.

[0046] Specifically, step S202 includes: Step S2021: Divide the first difference by the target coating saturation to obtain the saturation deviation.

[0047] Step S2022: Divide the second difference by the target relative humidity to obtain the humidity deviation.

[0048] Step S2023: Multiply the saturation deviation by the corresponding first preset weighting coefficient to obtain the first weighted deviation.

[0049] Step S2024: Multiply the humidity deviation by the corresponding second preset weighting coefficient to obtain the second weighted deviation.

[0050] Step S2025: Add the first weighted deviation, the second weighted deviation, and the preset benchmark weight factor to obtain the power adjustment weight.

[0051] In this embodiment of the invention, the calculated first difference ΔCS can be divided by the target coating saturation CStarget to obtain the saturation deviation, and then the saturation deviation can be multiplied by a preset first weighting coefficient to obtain the first weighted deviation; alternatively, the second difference ΔRH can be divided by the target relative humidity RHtarget to obtain the humidity deviation, and then the humidity deviation can be multiplied by a preset second weighting coefficient to obtain the second weighted deviation. The first and second weighting coefficients are related to the influence of environmental factors and reflect the optimization for specific scenarios (such as precision manufacturing). The first weighting coefficient is 0.1 and the second weighting coefficient is 0.2, which is only an example.

[0052] In this embodiment of the invention, the power adjustment weight is obtained by adding the first weighted deviation, the second weighted deviation, and the preset benchmark weighting factor using the following formula, and then adjusting the rated power to obtain the target dehumidification power: P(t)=Pbase×(1+0.2×ΔRH / RHtarget+0.1×ΔCS / CStarget ) Where P(t) represents the target dehumidification power; Pbase represents the rated power; and the power adjustment weight is represented as (1+0.2×ΔRH / RHtarget+0.1×ΔCS / CStarget).

[0053] This invention eliminates deviations and misjudgments caused by differences in target values ​​through difference normalization, ensuring the stability of dehumidification control. Furthermore, the designed weighting coefficient is related to the degree of influence of environmental factors, enabling precise control in specific scenarios.

[0054] Furthermore, the second preset weight coefficient is obtained through the following steps: determining whether the ambient relative humidity is greater than the second preset humidity threshold, the second preset humidity threshold being greater than the first preset humidity threshold; if the ambient relative humidity is greater than the second preset humidity threshold, setting the first weight value as the second preset weight coefficient; if the ambient relative humidity is not greater than the second preset humidity threshold, setting the second weight value as the second preset weight coefficient, the second weight value being less than the first weight value.

[0055] In this embodiment of the invention, when the relative humidity of the environment is determined to be greater than a first preset humidity threshold and dehumidification of the energy storage system is performed, the relationship between the relative humidity of the environment and a second preset humidity threshold can be compared first. The second preset humidity threshold is greater than the first humidity threshold. For example, if the relative humidity is 90%, it indicates that the humidity is approaching a high-risk level. A higher first weight value can be set as the second preset weight coefficient, for example, 0.2. This controls the dehumidification device to operate at a higher power, achieving rapid humidity reduction and preventing the spread of risk. When the relative humidity of the environment is less than the second preset humidity threshold, the risk level is lower. A lower second weight value can be set as the second preset weight coefficient, for example, 0.1. This controls the dehumidification device to operate at a gentler power, controlling humidity while avoiding excessive intervention and reducing energy consumption costs.

[0056] This invention further refines the setting logic of weight coefficients for different humidity ranges, enabling the weight coefficients to be flexibly adjusted according to the ambient humidity, thereby improving the environmental adaptability of the weight coefficients, ensuring that high risks are not ignored and resources are not wasted in dealing with low risks.

[0057] In one optional implementation, while controlling the operation of the dehumidification device based on the target dehumidification power to dehumidify the energy storage system, the ventilation device can also be controlled to operate at a first wind speed setting; the rate of decrease of the ambient relative humidity is monitored; if the rate of decrease of the ambient relative humidity is less than a first preset rate threshold, the ventilation device is switched to a second wind speed setting, where the wind speed of the second wind speed setting is greater than the wind speed of the first wind speed setting.

[0058] In this embodiment of the invention, after the dehumidification device (such as a dehumidifier) ​​is started to perform dehumidification, the ventilation device can be controlled to operate at a first fan speed setting, wherein the first fan speed setting is a low speed setting to promote air circulation; during the dehumidification and ventilation process, the rate of decrease of ambient relative humidity can be monitored. If the rate of decrease of ambient relative humidity is less than a first preset rate threshold (such as a decrease of 5%RH within 1 hour), the ventilation device can be switched to a second fan speed setting, wherein the second fan speed setting is a high speed setting to increase the rate of decrease of ambient humidity.

[0059] This invention uses multi-gradient ventilation-assisted control to not only improve the overall dehumidification effect of the energy storage system, but also reduce unnecessary energy consumption and ensure the stability of the environmental humidity of the energy storage system.

[0060] Step S203: Adjust the rated power based on the power adjustment weight to obtain the target dehumidification power. For details, please refer to [link to relevant documentation]. Figure 1 Step S103 of the illustrated embodiment will not be described again here.

[0061] Step S204: Control the operation of the dehumidification device based on the target dehumidification power to dehumidify the energy storage system. For details, please refer to [link to relevant documentation]. Figure 1 Step S104 of the illustrated embodiment will not be described again here.

[0062] In one optional implementation, when the controller detects that the saturation of the anti-condensation coating is less than a second saturation threshold and the relative humidity of the environment is less than a second preset humidity threshold, the controller controls the dehumidifier to switch to the off state.

[0063] The second saturation threshold is the minimum saturation value within the first preset saturation range.

[0064] The second preset humidity threshold is less than the first preset humidity threshold.

[0065] In the process of controlling the dehumidification device to dehumidify the energy storage system, when the saturation of the anti-condensation coating is detected to be less than the second saturation threshold (taking 40% as an example) and the relative humidity of the environment is less than the second humidity threshold (taking 55%RH as an example), it indicates that the current environmental humidity of the energy storage system meets the normal operation requirements. The dehumidification device can be switched to the off state, or the dehumidification device can be controlled to dehumidify the energy storage system at the rated power, or the operating power of the dehumidification device can be reduced to dehumidify the energy storage system at a lower dehumidification power. No limitation is made.

[0066] When the current ambient humidity of the energy storage system meets the requirements for normal operation, the present invention can shut down the dehumidification mode to save energy.

[0067] In one optional implementation, after the controller in the energy storage system controls the dehumidification device to switch to the off state, it monitors the first duration for which the dehumidification device remains in the off state; when the first duration reaches a first preset duration threshold, it switches the ventilation device to the off state.

[0068] In this embodiment of the invention, after the dehumidification device is switched to the off state, the ventilation device remains in the on ventilation state to use residual heat to remove residual moisture. At this time, the first duration of the dehumidification device being in the off state can be monitored. When the first duration of the dehumidification device being in the off state reaches the first duration threshold (taking 10 minutes as an example), the ventilation device can be switched to the off state.

[0069] This invention controls the ventilation device to utilize the waste heat from the dehumidification device to remove residual moisture, thereby improving the dehumidification effect of the energy storage system and ensuring the environmental stability of the energy storage system.

[0070] In one optional implementation, the controller records a second duration of operation of the dehumidifier while controlling its operation; it also detects the ambient relative humidity in real time and calculates the change in ambient relative humidity; when the second duration exceeds a second preset duration threshold and the change in ambient relative humidity is less than a preset humidity change threshold, the controller switches the dehumidifier to the off state and sends a prompt message to the user indicating an abnormal dehumidification operation.

[0071] In the process of controlling the operation of the dehumidification device, this embodiment of the invention can record the second duration of the dehumidification device's operation and detect the relative humidity of the environment in real time to determine the amount of change in the relative humidity of the environment. If the detected second duration is greater than the second duration threshold (taking 3 hours as an example), but the amount of change in the relative humidity of the environment is less than the preset humidity change threshold, such as when the relative humidity of the environment does not decrease or the decrease in humidity value is small, the dehumidification device can be shut down in time and a prompt message of dehumidification operation abnormality can be sent to the user.

[0072] When dehumidification is determined to be ineffective, this invention can promptly terminate the operation of the dehumidification device to avoid energy waste, and provide the user with a prompt message indicating abnormal dehumidification operation, enabling the user to repair the dehumidification device in a timely manner, extending the service life of the dehumidification device, and ensuring the stable operation of the energy storage system.

[0073] In one optional implementation, the controller determines whether the saturation of the anti-condensation coating of the current energy storage system is less than the third coating saturation threshold; if the saturation of the anti-condensation coating of the current energy storage system is less than the third coating saturation threshold, the controller controls the coating execution device to perform an adding operation on the anti-condensation coating until the saturation of the anti-condensation coating of the current energy storage system is not less than the third coating saturation threshold.

[0074] The embodiments of the present invention can monitor the saturation of the anti-condensation coating (including but not limited to parameters such as coating thickness and coverage) in real time. If the saturation of the anti-condensation coating of the current energy storage system is detected to be less than the third coating saturation threshold, wherein the third coating saturation threshold is less than the second saturation threshold, the coating execution device can be prioritized to perform an addition operation on the anti-condensation coating. The coating execution device is a spraying device, a coating curing device, etc., which is only an example. After the saturation of the anti-condensation coating reaches the standard, the above-mentioned dehumidification control method is then executed.

[0075] When the current anti-condensation coating saturation is determined to be less than the third coating saturation, the present invention can prioritize the coating addition operation, and start the dehumidification control only after the standard is met, thereby reducing unnecessary energy consumption and equipment damage.

[0076] In one optional implementation, during the relative humidity initialization phase, the humidity acquisition device can be pre-calibrated using a standard humidity generator to record the initial humidity value. Then, a dynamic humidity threshold range can be set based on this initial humidity value. This dynamic humidity threshold range represents the safe relative humidity threshold range corresponding to the operation of the energy storage system. The relative humidity collected by the humidity acquisition device is acquired in real-time or at fixed time intervals. It is determined whether the collected relative humidity is within the set safe threshold range. If it is not within the set safe threshold range, a backup humidity acquisition device can be activated to collect the relative humidity of the current energy storage system environment. The difference between the relative humidity collected by the two humidity acquisition devices is determined.
