Description

Technical Field

[0001] The present invention relates to the technical field of energy storage power stations, and particularly to a management device for energy storage battery modules used in energy storage power stations. Background Art

[0002] As a key component of modern power systems, an energy storage power station is a facility that converts electrical energy into other forms of energy for storage through specific technical means and releases it back to the power grid when needed. It plays an important role in alleviating the contradiction between power supply and demand and ensuring the safe and stable supply of energy by smoothing the fluctuations of renewable energy power generation, enhancing the peak shaving capacity of the power grid, and optimizing the allocation of power resources. The energy storage battery module is the core unit of the energy storage power station. It is composed of multiple battery cells connected in series and parallel, and integrated with a battery management system, a heat dissipation structure, and electrical connection components. It is the basic module for realizing the storage and release of electrical energy. The performance and stability of the battery module directly affect the overall operation efficiency and service life of the energy storage power station.

[0003] Since a large amount of heat is generated during the charging and discharging process of the battery, if the heat cannot be dissipated in time and effectively, the continuous increase in the battery temperature will lead to an accelerated decline in battery performance, shortened life, and even safety risks such as thermal runaway. Therefore, it is crucial to perform efficient heat dissipation management on the energy storage battery modules used in energy storage power stations. However, the existing heat dissipation technologies still have significant defects: on the one hand, most devices only use single-point temperature monitoring, making it difficult to accurately capture the temperature differences in various regions of the battery module, resulting in the inability to perform targeted heat dissipation on local high-temperature regions, and there are heat dissipation blind spots and resource waste; on the other hand, traditional heat dissipation systems ignore the influence of external environmental factors on the heat dissipation efficiency. Even when the external environmental temperature is low and the natural ventilation conditions are good, they still continuously rely on high-energy-consuming heat dissipation devices such as fans, causing unnecessary energy consumption, increasing the operating cost, and shortening the service life of the equipment, and cannot meet the dual requirements of accurate temperature control and energy conservation and consumption reduction of the heat dissipation system for energy storage power stations. For this reason, we provide a management device for energy storage battery modules used in energy storage power stations to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to make up for the deficiencies of the existing technology and provide a management device for energy storage battery modules used in energy storage power stations.

[0005] To achieve the above object, the present invention provides the following technical solution: A management device for energy storage battery modules used in an energy storage power station, including a box body, a box door is installed on the front surface of the box body, an intelligent controller and an environment sensor are installed on the front surface of the box door, and the intelligent controller and the environment sensor are electrically connected through wires. Two groups of slide rails are installed on the inner wall of the box body. A breathable plate is arranged inside the box body, and the end of the breathable plate is slidably connected to the inner wall of the slide rail. An energy storage battery pack is placed on the upper surface of each breathable plate. A baffle is installed on the upper surface of each breathable plate. A temperature sensor is installed on the upper surface of each baffle, and the temperature sensor is electrically connected to the intelligent controller through a wire. A fixing component is installed on the upper surface of each breathable plate. Ventilation slots one are opened on the left and right side surfaces of the box body.

[0011] Further, the intelligent controller is built-in with an intelligent algorithm. The intelligent algorithm includes a data fusion module, a threshold judgment module, and a control instruction generation module; The data fusion module is used to collect in real time the environmental temperature monitored by the environment sensor and the air flow velocity parameters, as well as the real-time temperature data of the energy storage battery packs in each area inside the box body monitored by each temperature sensor , and fuse these data, and calculate the comprehensive temperature data using the following fusion formula : , where is the number of temperature sensors, , are the weight coefficients dynamically adjusted according to the battery module characteristics and environmental impact factors, , , and ; The threshold judgment module analyzes and judges the fused data according to the preset temperature threshold . When , the control instruction generation module is triggered; The control instruction generation module calculates the required rotational speed adjustment value and the power adjustment value of the corresponding cooling fan according to the deviation between and .

[0012] Further, the intelligent algorithm is also provided with an adaptive adjustment module.

The heat dissipation component 18 includes an air outlet frame 181. Two mounting plates 182 are installed on the outer surface of the air outlet frame 181. The two mounting plates 182 are connected to the box body 1 through mounting bolts 183. Two heat dissipation fans 184 are installed on the inner wall of the air outlet frame 181.

[0021] A handle groove 7 is provided on the upper surface of each air-permeable plate 6, a partition plate 10 is installed on the outer surface of each baffle 9, and the partition plate 10 is adapted to the energy storage battery pack 8. A second ventilation groove 15 is provided on the upper surface of the box body 1, a second filter screen 16 is installed on the inner wall of the second ventilation groove 15, and a dust-proof cover 17 is installed on the upper surface of the box body 1.

[0022] In this embodiment, the box body 1 serves as the load-bearing main body of the entire device, providing an installation space for the internal components. The box door 2 is installed on the front of the box body 1 through conventional connection means such as hinges, facilitating operation and maintenance of the inside of the box. The intelligent controller 3 and the environmental sensor 4 are connected to the electrical interfaces on the box door 2 through wires to achieve electrical connection and ensure stable signal transmission. The two slide rails 5 are installed on the inner wall of the box body 1 through fixing means such as bolts, providing a sliding track for the air-permeable plate 6, enabling the air-permeable plate 6 to move smoothly inside the box. The air-permeable plate 6 is connected to the slide rail 5 through an embedded sliding connection, ensuring the stability of the connection. The energy storage battery pack 8 is placed on the upper surface of the air-permeable plate 6 and contacts the air-permeable plate through gravity to achieve the functions of storing and releasing electrical energy. The baffle 9 is vertically installed on the upper surface of the air-permeable plate 6 to block the energy storage battery pack 8 and prevent it from shifting. The temperature sensor 11 can accurately monitor the temperature around the energy storage battery pack 8 and transmit the data to the intelligent controller 3 in real time. The first ventilation grooves 13 are provided on the left and right side surfaces of the box body 1, and the first filter screen 14 is fixed on the inner wall of the first ventilation groove 13 through means such as card slots or adhesives to filter the air entering the box and prevent impurities such as dust from entering.

[0023] The air outlet frame 181 in the heat dissipation assembly 18 is fixedly connected to the back of the box body 1 through the mounting plate 182 and the mounting bolts 183. Two heat dissipation fans 184 are installed on the inner wall of the air outlet frame 181 to discharge the hot air inside the box. The handle groove 7 is provided on the upper surface of the air-permeable plate 6 to facilitate pulling the air-permeable plate 6.

These components cooperate with each other to jointly achieve functions such as heat dissipation, fixing, and monitoring of the energy storage battery pack 8.

[0024] The working steps of this embodiment are as follows: Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 And Figure 6As shown in the figure, first, the environmental sensor 4 monitors parameters such as the external environmental temperature and air flow velocity in real time and transmits the data to the intelligent controller 3. At the same time, the temperature sensor 11 monitors the temperature of each area of the energy storage battery pack 8 in real time and transmits the temperature data to the intelligent controller 3. After receiving these data, the intelligent controller 3 performs fusion analysis using the built-in algorithm. When the temperature of the energy storage battery pack 8 does not exceed the preset threshold, if the external environment is suitable, the intelligent controller 3 controls the cooling fan 184 to operate at a low power or stop operating, mainly relying on natural ventilation for heat dissipation, that is, the external cold air enters the interior of the box through the first ventilation slot 13 and the second ventilation slot 15, and the hot air is discharged through the air outlet frame 181 to achieve heat exchange. When the temperature of the energy storage battery pack 8 exceeds the preset threshold, the intelligent controller 3 accurately controls the rotation speed and power of the cooling fan 184 according to the temperature difference in each area to perform targeted heat dissipation on the area with a higher temperature. For example, if the temperature of a certain area is too high, the intelligent controller 3 increases the rotation speed of the cooling fan 184 near the corresponding position to accelerate the discharge of hot air.

[0025] Embodiment 2 As Figure 3 、 Figure 4 and Figure 5 As shown in the figure, the fixing component 12 includes a connecting plate 121 fixedly connected to the upper surface of the breathable plate 6. The outer surface of the connecting plate 121 is threadedly connected with a threaded rod 122. A rotating block 123 is installed at the end of the threaded rod 122. One end of the threaded rod 122 away from the rotating block 123 is rotatably connected to a fixing plate 124. A protective strip 125 is installed on the outer surface of the fixing plate 124, and the protective strip 125 is in contact with the energy storage battery pack 8. Two guide cylinders 126 are installed on the outer surface of the connecting plate 121. The inner walls of the two guide cylinders 126 are both slidably connected with guide rods 127, and one end of the guide rod 127 away from the guide cylinder 126 is connected to the fixing plate 124.

[0026] In this embodiment, all parts of the fixing component 12 are tightly connected and work together. The connecting plate 121 is firmly fixed on the upper surface of the air-permeable plate 6, providing an installation basis for the entire fixing component. Its connection method with the air-permeable plate 6 ensures that it will not loosen during long-term use. The threaded rod 122 is connected to the connecting plate 121 through precise thread fitting, ensuring that when the threaded rod 122 is rotated, the fixing plate 124 can be stably driven to move. The rotating block 123 is tightly connected to the end of the threaded rod 122, facilitating the operator to manually apply force to rotate the threaded rod 122. The fixing plate 124 is installed at one end of the threaded rod 122 away from the rotating block 123 by means of rotational connection, enabling the fixing plate 124 to move flexibly under the drive of the threaded rod 122 while maintaining a certain stability. The protective strip 125 is in direct contact with the energy storage battery pack 8, playing a buffering and protective role to prevent the fixing plate 124 from damaging the energy storage battery pack 8. The guide rod 127 is connected to the guide cylinder 126 by sliding fit. One end of the guide rod 127 is fixedly connected to the fixing plate 124, which can effectively limit the moving direction of the fixing plate 124, enabling it to move smoothly closer to or away from the energy storage battery pack 8 under the drive of the threaded rod 122, ensuring the accuracy and reliability of the fixing process.

[0027] The working steps of this embodiment are as follows: As Figure 3 , Figure 4 and Figure 5 shown, when installing the energy storage battery pack 8, first pull out the air-permeable plate 6 along the slide rail 5 by a part from the box body 1, place the energy storage battery pack 8 on the upper surface of the air-permeable plate 6, and use the partition plate 10 to preliminarily separate and position the energy storage battery pack 8. Then, rotate the rotating block 123. The rotating block 123 drives the threaded rod 122 to rotate on the connecting plate 121. Due to the guiding effect of the guide rod 127 and the guide cylinder 126, the fixing plate 124 can only move along the direction of the guide rod 127. The rotation of the threaded rod 122 is converted into the linear movement of the fixing plate 124, making the fixing plate 124 gradually approach the energy storage battery pack 8, so that the fixing plate 124 applies an appropriate pressure to the energy storage battery pack 8, firmly clamping the energy storage battery pack 8 between the fixing plate 124 and the baffle 9 to complete the fixing of the energy storage battery pack 8. When the energy storage battery pack 8 needs to be disassembled or maintained, rotate the rotating block 123 in the reverse direction, so that the threaded rod 122 drives the fixing plate 124 away from the energy storage battery pack 8, releasing the clamping of the energy storage battery pack 8, facilitating the removal of the energy storage battery pack 8 for subsequent operations.

[0028] Embodiment Three As Figure 7 and Figure 8 shown, the intelligent controller 3 is built-in with an intelligent algorithm, and this intelligent algorithm includes a data fusion module, a threshold judgment module, and a control instruction generation module; The data fusion module is used to collect the ambient temperature monitored by the environmental sensor 4 in real time 1. Air flow velocity parameters, and the real-time temperature data of the energy storage battery packs 8 in each area of the box body 1 monitored by each temperature sensor 11 , and fuse these data, and calculate the comprehensive temperature data by using the following fusion formula : , where is the number of temperature sensors, , is the weight coefficient dynamically adjusted according to the battery module characteristics and environmental impact factors, , , and ; The threshold judgment module is based on the preset temperature threshold , and analyzes and judges the fused data . When , the control instruction generation module is triggered; The control instruction generation module calculates the required rotational speed adjustment value and power adjustment value of the corresponding cooling fan 184 according to the deviation between and .

[0029] The intelligent algorithm also has an adaptive adjustment module. When the external environmental temperature is low and the air flow velocity meets the natural ventilation conditions, the adaptive adjustment module judges whether to switch to the natural ventilation-based cooling mode according to the data of the environmental sensor 4, and uses the natural ventilation judgment formula: , where is the reference temperature value, , are the judgment coefficients set according to the actual operating environment and the heat dissipation requirements of the battery module. When , this module sends an instruction to the control instruction generation module, and the control instruction generation module reduces the power of the cooling fan 184 to the low-power auxiliary state, where is the set natural ventilation start threshold. During the natural ventilation process, the adaptive adjustment module continuously monitors the environmental parameters and the battery temperature. When the battery temperature shows abnormal changes and the environmental conditions no longer meet the natural ventilation requirements, the adaptive adjustment module timely notifies the control instruction generation module to restore the normal power operation of the cooling fan 184.

[0030] In this embodiment, each module inside the intelligent controller 3 is connected through circuits to work collaboratively. The data fusion module is connected to the environmental sensor 4 and the temperature sensor 11 through wires to obtain the real-time environmental temperature, air flow velocity, and the real-time temperature data of the energy storage battery packs 8 in each area of the box body 1 in real time. These data are transmitted to the data fusion module through specific communication protocols and interfaces to ensure the accuracy and timeliness of data transmission. The threshold judgment module is connected to the data fusion module through internal circuits, receives the fused comprehensive temperature data, and compares and analyzes it with the preset temperature threshold. The control instruction generation module is connected to the threshold judgment module and the cooling fan 184. When the threshold judgment module triggers the control instruction generation module, the control instruction generation module calculates the required rotational speed adjustment value and power adjustment value of the cooling fan 184 according to the deviation between the comprehensive temperature data and the threshold, and controls the operating state of the cooling fan 184 through electrical signals. The adaptive adjustment module is connected to the environmental sensor 4 and the control instruction generation module, calculates the judgment value using the natural ventilation judgment formula based on the environmental temperature and air flow velocity data monitored by the environmental sensor 4. When the judgment value meets the switching condition, it sends an instruction to the control instruction generation module, and the control instruction generation module adjusts the power of the cooling fan 184 accordingly.

[0031] The working steps of this embodiment are as follows: As Figure 7 and Figure 8 shown, the data fusion module continuously collects the environmental temperature , air flow velocity monitored by the environmental sensor 4, and the real-time temperature data of the energy storage battery packs 8 in each area of the box body 1 monitored by each temperature sensor 11 . Then, the data fusion module calculates the comprehensive temperature data using the fusion formula . After the threshold judgment module receives the comprehensive temperature data , it compares it with the preset temperature threshold . If , it triggers the control instruction generation module. The control instruction generation module calculates the required rotational speed adjustment value of the cooling fan 184 according to the deviation between and and the power adjustment value , and sends a control signal to the cooling fan 184 to adjust its rotational speed and power, and performs targeted heat dissipation on the energy storage battery packs 8. During operation, the adaptive adjustment module judges whether the natural ventilation condition is met using the natural ventilation judgment formula according to the data of the environmental sensor 4. When , the adaptive adjustment module sends an instruction to the control instruction generation module, and the control instruction generation module reduces the power of the cooling fan 184 to the low-power auxiliary state to perform heat dissipation using natural ventilation.
