[0002] Currently, energy storage containers primarily use air and liquid cooling technologies for temperature management. However, these methods have limited adaptability and speed in extreme temperature conditions, making it difficult for battery cells to quickly reach and maintain an appropriate operating temperature range. This impacts the performance and lifespan of the cells, potentially limiting the efficiency and stability of the entire energy storage system.

[0003] Therefore, the core issue is that existing temperature regulation methods have limitations when dealing with seasonal and temperature fluctuations, and are unable to meet the high temperature control requirements of battery cells within energy storage containers. This includes difficulties in effectively dissipating heat in high-temperature environments and in rapidly heating the battery cells to maintain their optimal operating temperature range in low-temperature environments. This limitation not only affects the performance of the battery cells, but can also increase energy consumption and operating costs, and even adversely affect the long-term health of the battery cells. Based on this, the present application provides an energy storage container. Summary of the Invention

[0019] The following diagrams illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the illustrations, some commonly used structures and components are depicted in a simplified schematic manner.

[0020] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0021] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 as well as Figure 6 With the proposal of carbon peak and carbon neutrality goals, the new energy industry is developing rapidly. Thanks to the rapid development of the energy storage industry, the demand for electricity in energy storage power stations has also increased. Therefore, there are more and more outdoor large-capacity energy storage containers in power stations. Different temperature adjustments need to be made in different seasons and different temperature conditions, so that the battery cells in the energy storage containers can operate at their appropriate temperatures. Existing energy storage containers rely solely on air cooling and liquid cooling for heat dissipation adjustment, and have low adaptability to temperature. In summer and winter conditions, the battery cells cannot quickly and stably operate at an appropriate temperature. Based on this, the present application provides an energy storage container, including a battery cluster 4 for energy storage and an energy storage box 1 for carrying the battery cluster 4. The energy storage box 1 includes a box body 11, and one or more frames 13 are provided inside the box body 11. The frames 13 divide the inner space of the box body 11 into one or more areas for installing the battery cluster 4; A through hole is provided on one side of the frame 13 close to the battery cluster 4. A separator 3 is inserted into the through hole to separate two adjacent battery clusters 4. The top of the box body 11 is provided with a through hole adapted to the partition 3 to facilitate the removal of the partition 3. A sealing assembly 2 is provided at one end of the partition 3 at the top of the box body 11 to ensure the airtightness of the battery cluster 4 and the box body 11.

[0022] See Figure 1The energy storage box 1 has a monolithic frame structure, with one or more skeletons 13 positioned within the box body 11. These skeletons 13, through a rational layout, divide the interior of the box body 11 into one or more independent zones, each of which can accommodate a battery cluster 4. This partitioning design not only facilitates the installation and maintenance of the battery clusters 4, but also allows for flexible adjustment of the battery cluster 4 layout based on actual needs.

[0023] The frame 13 has through-holes on one side near the battery clusters 4. Separators 3 are inserted into these through-holes. The primary function of separators 3 is to physically separate two adjacent battery clusters 4, preventing direct contact between them and thus preventing heat transfer or chemical reactions. Separators 3 can be made of various barrier materials as needed, such as high-thermal conductivity materials for rapid heat dissipation or low-thermal conductivity materials for heat preservation.

[0024] See Figure 1 and Figure 2 To facilitate quick replacement of the partitions 3, the top of the housing 11 is provided with through-holes adapted for the partitions 3. These holes allow the partitions 3 to be easily pulled out from the top, making it convenient for personnel to replace partitions 3 of different materials as needed. One end of the partition 3 is located at the top of the housing 11 and engages with the sealing assembly 2 to ensure airtightness and sealing between the battery cluster 4 and the housing 11, preventing the external environment from affecting the internal battery cluster 4.

[0025] The material of the separator 3 can be selected based on the ambient temperature and the operating state of the battery cluster 4. For example, in high-temperature environments, a high-thermal-conductivity material (such as metal or graphene-based materials) can be selected to enhance heat dissipation; in low-temperature environments, a low-thermal-conductivity material (such as foam plastic or insulation material) can be selected to reduce heat loss.

[0026] The structural design of the partition 3 can be further optimized, for example, by providing a heat conduction channel or a heating / cooling device inside the partition 3 to achieve active regulation of the temperature of the battery cluster 4 .

[0027] The sealing assembly 2 is located on top of the partition 3 and is used to ensure airtightness between the battery cluster 4 and the box body 11 , thereby preventing external moisture, dust or other pollutants from entering the box body 11 , thereby protecting the performance and life of the battery cluster 4 .

[0028] The sealing assembly 2 can also monitor the temperature and pressure changes inside the box 11 in real time through a temperature or pressure monitoring device, thereby further improving the safety and stability of the energy storage system.

[0029] The interchangeable bulkhead 3 design allows the energy storage container to quickly adjust the bulkhead 3 material based on varying ambient temperatures and seasonal requirements (e.g., summer vs. winter), thereby improving temperature regulation efficiency. For example, high-thermal-conductivity materials can be used to enhance heat dissipation in high-temperature environments, while insulating materials can be used to minimize heat loss in low-temperature environments.

[0030] The partition 3 not only achieves physical isolation between the battery clusters 4, but also avoids heat transfer or chemical reaction between the battery clusters 4, thereby reducing the risk of overheating or short circuit of the battery cluster 4 and improving the safety of the energy storage system.

[0031] The quick replacement of partitions 3 allows the energy storage container to adapt to temperature regulation requirements under different environmental conditions. For example, high-thermal conductivity partitions 3 can be replaced in the summer heat, and thermal insulation partitions 3 can be replaced in the winter to ensure that the battery cluster 4 always operates within the optimal temperature range.

[0032] The design of the top through-hole and the sealing assembly 2 makes the replacement and adjustment of the partition 3 more convenient, reducing maintenance time and cost. At the same time, the airtight design and the use of the sealing assembly 2 further improve the reliability and durability of the energy storage system.

[0033] Through reasonable temperature regulation, the energy storage system can reduce unnecessary energy consumption, such as reducing energy consumption during cooling or heating, thereby improving overall energy utilization efficiency.

[0034] See Figure 4 A partition 12 is further provided on the inner side of the box body 11 . The partition 12 is located on one side of the skeleton 13 and contacts the outer side of one group of battery clusters 4 .

[0035] See Figure 5 A high-voltage box 5 is provided inside the box body 11 in an area divided by the frame 13 , and the high-voltage box 5 is electrically connected to the battery cluster 4 .

[0036] In addition to the frame 13, the inner side of the box 11 is also provided with an interlayer 12. The interlayer 12 is located on one side of the frame 13 and directly contacts the outer side of one of the battery clusters 4. This design allows the interlayer 12 to more efficiently regulate the temperature of the battery cluster 4.

[0037] The primary function of the barrier layer 12 is to optimize heat exchange between the battery cluster 4 and the external environment through its material properties and structural design. For example, the barrier layer 12 can be constructed from a high-thermal-conductivity material (such as metal or thermally conductive silicone) to enhance heat dissipation, or a low-thermal-conductivity material (such as insulating foam or composite materials) to minimize heat loss. The thickness, material, and surface treatment of the barrier layer 12 can also be adjusted based on actual needs to achieve optimal temperature control.

[0038] In a complex environment, the interlayer 12 may be designed as a multi-layer structure, for example, an insulating layer or a buffer layer may be added between the heat-conducting layers to further improve the flexibility and stability of temperature regulation.

[0039] Inside the box 11, in the area divided by the frame 13, a high-voltage box 5 is provided. The high-voltage box 5 is located close to the battery cluster 4 and is electrically connected to the battery cluster 4 to achieve power supply and energy management.

[0040] The high-voltage box 5 is a crucial component of the energy storage system, responsible for managing the power input and output of the battery cluster 4. Its specific functions include collecting and distributing the power from the battery cluster 4, ensuring efficient operation of the energy storage system, achieving power balance between the battery clusters 4, preventing performance degradation or safety hazards caused by voltage differences between the battery clusters 4, and providing stable power output for connection to the external power grid or load.

[0041] The high-voltage box 5 is usually equipped with safety features such as short-circuit protection, overvoltage protection, and overcurrent protection to ensure the safety and reliability of the energy storage system. The casing of the high-voltage box 5 is usually made of insulating material to prevent the risk of electric shock or short circuit.

[0042] The barrier 12 regulates the temperature of the battery cluster 4, ensuring efficient charging and discharging within an appropriate temperature range. Simultaneously, the high-voltage box 5 optimizes the power output and input of the battery cluster 4 through power management, thereby improving the overall efficiency of the energy storage system. For example, in low-temperature environments, the barrier 12 can maintain the battery cluster 4 at an appropriate operating temperature through heating, while the high-voltage box 5 prevents overcharging or over-discharging of the battery cluster 4 through power regulation.

[0043] The temperature regulation function of the interlayer 12 can reduce the risk of overheating or overcooling of the battery cluster 4, while the safety protection function of the high-voltage box 5 can prevent malfunctions in the power management process. The synergistic effect of the two significantly improves the safety and stability of the energy storage system.

[0044] The insulation 12 allows the energy storage container to more flexibly adjust the temperature of the battery cluster 4 in different ambient temperatures. For example, in high-temperature environments, the highly thermally conductive insulation 12 dissipates heat, while in low-temperature environments, the thermal insulation 12 reduces heat loss. This flexibility significantly improves the efficiency of temperature regulation, ensuring that the battery cluster 4 always operates within the optimal temperature range.

[0045] See Figure 7 and Figure 8 The partition 3 includes a plate body 31 , and a fitting groove 32 is opened on the top of the plate body 31 , and the fitting groove 32 is adapted to the sealing component 2 .

[0046] A pull rod 33 is provided at the top middle portion of the plate body 31 , and the pull rod 33 is used to extract the plate body 31 for easy replacement.

[0047] A bottom plate 34 is provided at the bottom of the plate body 31 , and the bottom is fixed to the bottom of the box body 11 for removing and positioning the plate body 31 .

[0048] A positioning piece is provided on the top of the bottom plate 34 , and the positioning piece is inserted into the inner side of the plate body 31 , so that the bottom plate 34 and the plate body 31 are adapted to each other.

[0049] A partition is provided in the middle of the inner side of the plate body 31 , and an accommodation space is formed between the two sides of the partition and the inner wall of the plate body 31 . The accommodation space is filled with an isolation filler 35 , and the isolation filler 35 is sleeved with the outer side of the positioning piece.

[0050] The plate 31 is mainly used to separate adjacent battery clusters 4 . The plate 31 can be made of different barrier materials to meet different temperature regulation requirements.

[0051] The top of the plate 31 is provided with a fitting groove 32, which is adapted to the sealing component 2 at the top. The sealing assembly 2 includes a top plate and a rubber ring for sealing. The rubber ring fits into the fitting groove 32 to ensure that the partition 3 fits tightly with the sealing assembly 2 on the top of the box 11 after insertion, thereby ensuring airtightness between the battery cluster 4 and the box 11.

[0052] A pull rod 33 is provided at the top middle portion of the plate body 31. The main function of the pull rod 33 is to facilitate the operator to quickly pull out and replace the partition 3. The design of the pull rod 33 makes the installation and removal of the partition 3 more convenient and efficient.

[0053] The bottom of the plate body 31 is provided with a bottom plate 34, which is fixed to the bottom of the box body 11 and is mainly used to provide the extraction and positioning of the plate body 31. The design of the bottom plate 34 ensures the position accuracy and stability of the partition 3 when inserted.

[0054] A positioning piece is provided on the top of the bottom plate 34, which is plugged into the inner side of the plate body 31 so that the bottom plate 34 and the plate body 31 can be adapted to each other. The positioning piece not only ensures the stable installation of the partition 3, but also facilitates the rapid replacement of the plate body 31.

[0055] A partition is provided in the middle of the inner side of the plate body 31, which divides the inner side of the plate body 31 into two sides, forming two receiving spaces. These receiving spaces can be used to fill isolation fillers 35 made of different materials.

[0056] The insulating filler 35 is made of different materials depending on the temperature regulation requirements. For example, in high-temperature environments, a high-thermal-conductivity material (such as metal powder or graphene-based materials) can be used to enhance heat dissipation; in low-temperature environments, a low-thermal-conductivity material (such as foam plastic or insulation) can be used to reduce heat loss. The insulating filler 35 is fitted onto the outer side of the positioning member to ensure its secure and stable fit.

[0057] By filling the space within the plate 31 with insulating fillers 35 of varying materials, the partition 3 can quickly adjust its temperature control scheme based on varying ambient temperatures and seasonal requirements. For example, high-thermal-conductivity materials can be used to enhance heat dissipation during summer heat, while insulating materials can be used to reduce heat loss during winter cooler temperatures. This flexibility significantly improves the efficiency and adaptability of temperature control.

[0058] The matching design of the fitting groove 32 and the sealing assembly 2 ensures the airtightness of the partition 3 and facilitates the operator to quickly install and remove it. The setting of the pull rod 33 makes it easier to remove and replace the partition 3, simplifying the operation process and reducing maintenance costs.

[0059] The matching design of the bottom plate 34 and the positioning piece ensures the position accuracy and stability of the partition 3 when inserted, avoids the problem of loosening or displacement during use, and improves the reliability and safety of the system.

[0060] The partition 3 cooperates with the sealing assembly 2 on the top of the box 11 to ensure the airtightness between the battery cluster 4 and the box 11, preventing external moisture, dust or other pollutants from entering the box 11, thereby protecting the performance and life of the battery cluster 4.

[0061] The insulating filler 35 within the partition 3 can be made of different materials based on actual needs, ensuring stable operation of the battery cluster 4 within a suitable temperature range and avoiding performance degradation or safety hazards caused by temperature fluctuations. The temperature regulation function of the partition 3 works synergistically with the power management function of the high-voltage box 5 to significantly improve the overall efficiency of the energy storage system. By properly regulating the temperature of the battery cluster 4, unnecessary energy consumption can be reduced and the energy storage system's energy utilization efficiency can be improved. The partition 3 enables the energy storage container to adapt to different environmental conditions (such as high and low temperatures and humidity), improving the system's adaptability and environmental friendliness. Through a flexible temperature regulation mechanism, the energy storage system can reduce energy consumption caused by temperature fluctuations, thereby achieving a more environmentally friendly energy storage solution.

[0062] Example 2: The present application also provides an energy storage system configured with an energy storage container, which also includes a monitoring component, an early warning component, a fire protection component and a charging and discharging component. The monitoring component includes one or more sensors, which are distributed inside the box and electrically connected to the battery cluster; the early warning component includes a level determination component, which compares the characteristic numerical values ​​in the monitoring component with the set thresholds of each early warning level and determines the actual early warning level.

[0063] The charging and discharging components include a power monitoring unit, which is used to detect the power level of the battery modules in the energy storage box in real time and cooperate with the monitoring components to record the data; Time monitoring unit, recording the charging and discharging time of the battery modules in the energy storage box; The temperature unit is used to monitor the temperature of the battery module during charging and discharging, as well as the temperature value in the box.

[0064] The fire protection component includes an automatic fire extinguishing device to deal with potential fire risks.

[0065] Specifically, multiple sensors are distributed inside the box, including temperature sensors such as DS18B20, smoke sensors such as MQ-2, and gas sensors such as MH-Z14A. These sensors are electrically connected to the battery cluster to monitor key parameters such as temperature, smoke concentration, and gas concentration inside the box in real time.

[0066] At the same time, the data collected by the sensors is transmitted to the central processing unit through the data acquisition module, such as the TIBQ series or ADIADuCM series, which is suitable for battery monitoring and management tasks to ensure the accuracy and real-time nature of the data. The central processing unit is responsible for receiving, processing, and storing data from sensors and transmitting the data to the remote monitoring platform through a communication module. For example, the SIM7600 all-in-one communication module can meet complex application scenarios with multiple communication methods. The early warning component compares the monitored characteristic values ​​(such as temperature, smoke concentration, gas concentration, etc.) with the preset thresholds to determine the actual warning level.

[0067] Different levels of warning thresholds can be set based on different application scenarios and safety requirements. For example, a level 1 warning could be triggered when the temperature exceeds 40°C, while a level 2 warning could be triggered when the smoke concentration reaches a certain level.

[0068] When the monitored value exceeds the set threshold, the early warning component will automatically send a warning signal and notify the operator through an alarm light, sound alarm or remote notification (such as SMS, email, etc.).

[0069] Automatic fire extinguishing devices, such as carbon dioxide fire extinguishers and dry powder fire extinguishers, are installed in the box. When a fire risk is detected, the fire extinguishing device will automatically start and quickly extinguish the initial fire.

[0070] Smoke detectors are used in conjunction with automatic fire extinguishing devices to monitor the smoke concentration inside the box in real time, ensuring early detection and timely handling of fire risks.

[0071] In certain high-risk scenarios, an automatic sprinkler system may also be installed to further enhance the fire extinguishing effect.

[0072] At the same time, through the power monitoring unit, operators can understand the current status of the battery pack at any time to ensure that the battery pack operates within a safe range.

[0073] The time monitoring unit records the charge and discharge time of the battery module. Through the time monitoring unit, the charge and discharge cycle of the battery pack can be tracked to optimize the charge and discharge strategy and extend the battery life.

[0074] The temperature unit primarily monitors the temperature of the battery module during the charge and discharge process, as well as the temperature inside the battery box. This data, combined with the charge and discharge strategy, ensures that the battery pack operates within the appropriate temperature range, avoiding performance degradation and safety hazards caused by overheating or overcooling.

[0075] By using voltage and current sensors, such as the INA3221 integrated voltage and current sensor, the battery module's power can be monitored in real time to ensure the accuracy and real-time nature of the data. The monitored power data can be stored locally or uploaded to a remote monitoring platform for subsequent analysis and management.

[0076] Record the charge and discharge time of the battery module. The charge and discharge efficiency and health status of the battery pack can be analyzed through the charge and discharge time data. Based on the charge and discharge time data, the charge and discharge cycle of the battery pack can be optimized to extend the service life of the battery pack.

[0077] The temperature sensor monitors the temperature changes of the battery module during the charging and discharging process to ensure that the battery pack operates within a safe temperature range.

[0078] Combined with temperature control equipment (such as air conditioning system, cooling system), it automatically adjusts the temperature according to the monitored temperature data to optimize the charging and discharging environment of the battery pack.

[0079] Through smoke detectors and gas sensors, fire risks can be detected early and fire extinguishing equipment can be activated in time.

[0080] The fire extinguishing equipment uses highly effective fire extinguishing agents (such as carbon dioxide, dry powder, etc.) to ensure that initial fires can be quickly extinguished and prevent the fire from spreading.

[0081] The smoke detector monitors the smoke concentration in the box in real time and transmits the data to the central processing unit through the data acquisition module.

[0082] When the smoke concentration reaches the set threshold, the alarm signal is automatically triggered and the fire extinguishing device is activated.

[0083] In certain high-risk scenarios, sprinkler systems supplement firefighting components to further enhance fire extinguishing effectiveness.

[0084] The sprinkler system covers the entire interior of the box to ensure comprehensive fire extinguishing and prevent the spread of fire.

[0085] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible.
