Description

Technical Field

[0001] This utility model relates to the field of thermal management technology for energy storage equipment, specifically to a system that utilizes a gas film structure to provide adaptive thermal environment regulation for energy storage equipment. Background Technology

[0002] With the widespread application of energy storage power stations, containerized energy storage, and other facilities, thermal management of energy storage devices (such as lithium-ion battery clusters) has become crucial to ensuring their safety, efficiency, and lifespan. Overheating can lead to performance degradation or even thermal runaway, while excessively low temperatures affect charging and discharging efficiency. Currently, common temperature control solutions include installing air conditioning, forced air cooling, or liquid cooling systems within the equipment compartment. These solutions consume a lot of energy, and their operation is often independent of the real-time thermal state of the energy storage device, resulting in insufficient precision in response.

[0003] In the prior art, some solutions have emerged that utilize air-supported membranes for thermal insulation and cooling. For example, Chinese utility model patent application number 2023215515452 discloses an air-supported membrane cooling device and an energy storage container system, which achieves thermal insulation by forming an attached air-supported membrane layer on the surface of the energy storage container's outer shell. However, in such solutions, the air-supported membrane is typically a fixed auxiliary structure of the equipment's outer shell, with a single function, lacking the ability to dynamically and actively adjust according to changes in the core temperature inside the energy storage equipment. Its adjustment targets only the shape of the air-supported membrane itself, rather than the overall control of the equipment's thermal environment, thus failing to achieve intelligent linkage and on-demand response between the energy storage equipment and the enclosure structure. Utility Model Content

[0004] The purpose of this invention is to provide an air-film environmental regulation system that is linked with an energy storage module. This system can monitor the thermal state of the energy storage device in real time and intelligently adjust the heat dissipation or heat preservation characteristics of the air-film structure accordingly, thereby achieving efficient, energy-saving, and safe dynamic thermal management.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose an air-film environment regulation system that is linked with an energy storage module, including a status monitoring unit, a control unit and a structural adjustment unit.

[0006] The output of the status monitoring unit is connected to the input of the control unit and is used to collect parameters characterizing the thermal state of the energy storage device.

[0007] The output terminal of the control unit is connected to the control terminal signal of the structural adjustment unit, and is used to generate adjustment commands according to the parameters;

[0008] The structural adjustment unit is disposed on the air film structure and is used to change the physical state of the air film structure according to the adjustment command, so as to adjust its heat dissipation or heat preservation characteristics.

[0009] Furthermore, the status monitoring unit includes a first sensing subunit and a second sensing subunit;

[0010] The first sensing subunit is disposed inside or on the surface of the energy storage device and is used to collect the direct thermal state parameters of the energy storage device.

[0011] The second sensing subunit is located within the space enclosed by the air-film structure and is used to collect environmental state parameters.

[0012] Furthermore, the control unit is pre-set with linkage logic and is configured to generate the adjustment command based at least on the comparison result between the direct thermal state parameter and the preset threshold.

[0013] Furthermore, the linkage logic is also configured to: modify the adjustment command based on the environmental state parameters.

[0014] Furthermore, the structural adjustment unit includes an airflow adjustment subunit, which is used to change the airflow rate inside the air film structure or between the air film structure and the outside environment according to the adjustment command.

[0015] Furthermore, the air volume regulating subunit includes an air vent opening regulating component and / or a fan speed regulating component.

[0016] Furthermore, the structure adjustment unit includes a pressure adjustment subunit, which is used to change the pressure difference between the inside and outside of the air film structure according to the adjustment command.

[0017] Furthermore, the air pressure regulating subunit includes an inflation rate regulating component and / or a pressure relief valve opening regulating component.

[0018] Furthermore, the structure adjustment unit includes a light transmittance adjustment subunit, which is used to change the light transmittance of the air film structure locally or as a whole according to the adjustment command.

[0019] Furthermore, it also includes a safety warning unit; the input terminal of the safety warning unit is signal-connected to the status monitoring unit or the control unit, and is used to trigger a warning action when the parameter or the adjustment command meets the preset warning conditions.

[0020] The gas-film environment regulation system linked with an energy storage module proposed in this utility model has the following beneficial effects:

[0021] 1. By using the direct thermal state of the energy storage device as the primary input signal for regulating the air-film structure, the mode of independent operation of traditional air-film or air conditioning systems has been changed, realizing dynamic thermal management with "source-field" linkage, resulting in more direct temperature control, faster response, and more precise effect.

[0022] 2. The system integrates multiple adjustment methods such as air volume, air pressure, and light transmittance, allowing for the selection of the most economical and effective combination of adjustments based on internal and external environmental conditions. For example, during transitional seasons, natural ventilation and light transmittance adjustment are prioritized, significantly reducing the energy consumption of traditional temperature control systems.

[0023] 3. The system not only passively responds to temperature changes, but its continuous monitoring and intelligent analysis capabilities can also identify abnormal trends in advance. Combined with a safety early warning unit, it can provide early warning of thermal runaway, moving the safety defense line forward and significantly improving the overall safety of the energy storage power station.

Its hardware components (sensors, controllers, actuators) are all mature industrial products, which are easy to integrate into new or existing air-supported membrane energy storage facilities. It has good engineering practicality and promotion value. Attached Figure Description

[0027] Figure 2 This is a flowchart illustrating the linkage logic. Detailed Implementation

[0028] To more clearly illustrate the technical solutions in the embodiments of this utility model and the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

[0029] This utility model embodiment provides an air-supported membrane environment regulation system linked to an energy storage module. Please refer to [link to relevant documentation]. Figure 1 It includes a condition monitoring unit, a control unit, and a structural adjustment unit;

[0030] The output of the condition monitoring unit is connected to the input of the control unit to collect parameters characterizing the thermal state of the energy storage device.

[0031] The output of the control unit is connected to the control signal of the structural adjustment unit, and is used to generate adjustment commands based on the parameters.

[0032] The structural adjustment unit is installed on the air film structure and is used to change the physical state of the air film structure according to the adjustment command, so as to adjust its heat dissipation or heat preservation characteristics.

[0033] The system described in this application forms a complete closed loop of "perception-decision-execution". The status monitoring unit acts as the system's "sensors", continuously acquiring information such as the temperature of the energy storage device and the environment; the control unit acts as the "brain", analyzing information and making decisions based on preset logic; and the structural adjustment unit acts as the "limbs", executing decisions and physically changing the state of the air film. The three are combined into a single physical entity through defined signal connections, realizing direct and automatic linkage between the thermal state of the energy storage device and the characteristics of the air film structure.

[0034] The status monitoring unit includes a first sensing subunit and a second sensing subunit.

[0035] The first sensing subunit is located inside or on the surface of the energy storage device and is used to collect the direct thermal state parameters of the energy storage device.

[0036] The second sensing subunit is located within the space enclosed by the air-supported membrane structure and is used to collect environmental state parameters.

[0037] Specifically, the first sensing subunit (such as a temperature sensor attached to the battery module) directly acquires the temperature of the core equipment, which is the main basis for linkage control; the second sensing subunit (such as a temperature and humidity sensor suspended in the air film space) acquires spatial environmental parameters, providing background information and correction basis for control decisions, making the adjustment more precise; thus realizing dual data sources for monitoring.

[0038] In this application, the control unit is pre-set with linkage logic and is configured to generate adjustment commands based at least on the comparison results between the direct thermal state parameters and preset thresholds.

[0039] State adjustment is achieved through pre-set linkage logic within the control unit. For example, programs or fixed circuit logic stored in the controller chip form the basic operating logic of the system. Specific parameters monitored (such as "battery temperature 45℃") are compared with preset safety or high-efficiency operating thresholds (such as "set upper limit 40℃"), thereby triggering corresponding adjustment commands (such as "enhance heat dissipation"), realizing the automated conversion from data to action.

[0040] As a feasible solution, the linkage logic is also configured to modify the adjustment command based on environmental state parameters.

[0041] For example, when heat dissipation is required, if the second sensing subunit detects that the ambient temperature is very low, the control unit can instruct the use of a low-energy natural ventilation mode; if the ambient temperature is very high, it may instruct the activation of forced ventilation and close some air inlets to prevent hot air from flowing in. Through the fusion and judgment of multiple parameters, energy efficiency and regulation quality are improved.

[0042] The structural adjustment unit includes an air volume adjustment subunit, which is used to change the air flow rate inside the air film structure or between the air film structure and the outside world according to the adjustment command.

[0043] By changing the airflow rate, the rate of heat accumulation or dissipation within the air film space can be directly and quickly altered, making it one of the core physical methods for achieving heat dissipation or insulation.

[0044] As one possible embodiment, the air volume regulation subunit includes an air vent opening regulation component and / or a fan speed regulation component.

[0045] For example, ventilation opening adjustment components (such as motorized louvers or sliding window motors) adjust airflow by changing the opening area; fan speed adjustment components (such as variable frequency fans) adjust airflow by changing the power output. These components can be used individually or in combination to form the specific hardware structure for achieving airflow adjustment.

[0046] The structural adjustment unit includes a pressure adjustment subunit, which is used to change the pressure difference between the inside and outside of the air film structure according to the adjustment command.

[0047] The pressure difference between the inside and outside of the air-supported membrane directly affects its structural tightness and airtightness. Increasing the pressure difference makes the membrane tighter, reduces air leakage, and enhances its thermal insulation effect; appropriately decreasing the pressure difference increases air permeability and aids in heat dissipation. This allows for active control over the "structural characteristics" of the air-supported membrane itself.

[0048] As one possible embodiment, the air pressure regulating subunit includes an inflation rate regulating component and / or a pressure relief valve opening regulating component.

[0049] For example, an inflation rate regulating component (such as a variable frequency inflation blower) regulates pressure by controlling the intake air volume; a pressure relief valve opening regulating component (such as an electric pressure relief valve) regulates pressure by controlling the exhaust air volume. These two components are standard hardware that constitute the pressure regulating subunit.

[0050] The structural adjustment unit includes a light transmission adjustment subunit, which is used to change the light transmittance of the air-supported membrane structure locally or as a whole according to the adjustment command.

[0051] By adjusting the light transmittance (e.g., using electrochromic film or motor-driven sunshade curtains), the amount of solar radiation heat entering the air-supported membrane can be controlled. In summer, heat gain is reduced to assist in cooling, and in winter, heat gain is increased to assist in insulation. This is an energy-saving passive regulation method.

[0052] The system of this application also includes a safety warning unit. The input terminal of the safety warning unit is connected to the status monitoring unit or control unit for signal connection, and is used to trigger a warning action when the parameters or adjustment commands meet the preset warning conditions.

[0053] Safety warning units (such as audible and visual alarms, communication modules) can be used as independent or integrated functional modules to immediately issue local alarms or remote notifications when abnormal conditions such as a sharp rise in temperature (potential thermal runaway) or the regulation system failing to cool down despite continuous full-load operation are detected, thus buying time for manual intervention.

[0054] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. The description herein is merely exemplary and illustrative and should not be construed as limiting the scope of protection of this utility model.

[0055] When implementing this plan, the following information may be helpful:

[0056] Firstly, this system is applied to an outdoor containerized energy storage power station. The energy storage devices consist of multiple battery storage cabinets placed side by side, centrally located on a flat site. The air-supported membrane structure is an inflatable membrane structure whose edges are anchored to the ground, forming a large, enclosed or semi-enclosed space that completely covers all the aforementioned battery storage cabinets. The framework of the air-supported membrane structure is maintained in shape by internal air pressure.

[0057] The first sensing subunit of the condition monitoring unit (such as multiple temperature sensor probes) is directly positioned on the surface of key battery modules or at representative temperature measurement points within the battery cabinet. The second sensing subunit (such as temperature and humidity sensors, and air pressure sensors) is evenly distributed and suspended in the upper part of the internal space of the air-supported membrane structure. The control unit (such as an industrial PLC controller cabinet) is installed in a moisture-proof control box on one side of the air-supported membrane. The various components of the structural adjustment unit are integrated onto the air-supported membrane: the airflow adjustment subunit's inlet / outlet vents (with electric air valves) are distributed at the bottom and top of the air-supported membrane sidewalls; the air pressure adjustment subunit's inflation fan and electric pressure relief valve are installed in the air-supported membrane foundation equipment room; and the light transmittance adjustment subunit's electrochromic film area is distributed at the top of the air-supported membrane. All sensors and actuators are connected to the control unit via cables or wireless modules.

[0058] Based on the above deployment plan, the overall operation process of this application is as follows:

[0059] After the system is powered on, the status monitoring unit continues to operate. The first sensing subunit collects the core temperature of each battery cabinet, and the second sensing subunit collects the temperature, humidity, and air pressure data within the air-supported membrane space. This data is transmitted to the control unit in real time via signal lines.

[0060] The control unit's internal pre-set linkage logic analyzes the input data. The core of this logic is prioritizing the thermal state of the energy storage devices. For example, when the temperature of a battery cluster is detected to be consistently above a first threshold (e.g., 35°C), the control unit determines that enhanced heat dissipation is needed. At this point, it combines data from the second sensing subunit (e.g., high temperature inside the gas film, low outside temperature) to make a decision.

[0061] After making the decision, the control unit sends specific adjustment commands to the structural adjustment unit. Continuing with the example of needing to enhance heat dissipation, the control unit might simultaneously issue the following commands:

[0062] 1) Send a command to the air volume regulation subunit to fully open the electric air valves of the bottom air inlet and the top air outlet, and start the exhaust fan to the high speed to create a "chimney effect" to enhance forced convection;

[0063] 2) Send a command to the air pressure regulation subunit to fine-tune the opening of the pressure relief valve, so as to slightly reduce the internal pressure of the air film, reduce its absolute airtightness, and assist in natural air infiltration for heat dissipation.

[0064] 3) Send instructions to the light transmittance adjustment subunit to reduce the light transmittance of the top area of ​​the air film and reduce solar radiation heat gain.

[0065] The components of the structural adjustment unit execute commands, physically altering the ventilation characteristics, air pressure, and light transmittance of the air-supported membrane structure. These combined effects rapidly transform the interior space of the air-supported membrane from a relatively stuffy environment to one with smooth airflow and enhanced heat exchange, thus efficiently removing the heat generated by the energy storage device and bringing its temperature back to a safe range.

[0066] Conversely, when heat preservation is needed in winter or at night, the control unit can instruct the vents to close, increase the internal pressure to enhance airtightness, and increase the light transmittance to utilize solar radiation, thereby effectively preserving the heat generated during equipment operation and preventing the temperature from becoming too low.

[0067] Throughout the process, the safety warning unit monitors the data stream in real time. If, after the control unit issues a maximum heat dissipation command, the temperature data of the first sensing subunit fails to decrease within a predetermined time or even rises rapidly, the safety warning unit will determine it as abnormal, immediately trigger an audible and visual alarm, and send an emergency alarm message to the remote monitoring center via the communication module.

[0068] See Figure 2The decision-making process begins with receiving the direct temperature (T_batt) of the energy storage device. The control unit first compares it with preset cooling thresholds (T_cool) and heat preservation thresholds (T_heat) to determine the basic operating mode (heat dissipation, heat preservation, or equilibrium).

[0069] In "Enhanced Heat Dissipation" mode, the specific strategy will be further selected based on the ambient temperature (T_env). If the outside is cool, low-energy natural convection will be prioritized; if the outside is hot, forced circulation will be activated and efforts will be made to block external heat.

[0070] In "heat preservation" mode, the strategy will be selected based on the lighting conditions. It will either passively store heat using sunlight or actively preserve heat by improving airtightness.

[0071] After generating the initial instructions, a safety condition judgment step is added to the process. This step integrates a final verification of the reasonableness of power supply, communication, and sensor readings. Regardless of whether the normal path or the safety warning path is used, a specific and executable set of adjustment instructions will ultimately be output and sent to the structural adjustment unit.

[0072] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

It should not be construed that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
