Description

Technical Field

[0001] This utility model relates to an inter-cluster isolation temperature control structure for energy storage containers, belonging to the field of energy storage container equipment. Background Technology

[0002] Energy storage containers, as an important component of modern energy storage systems, are widely used in renewable energy grid connection and grid peak shaving. A single energy storage container typically houses multiple battery clusters, each composed of several battery modules. Because batteries generate heat during charging and discharging, the operating states of different battery clusters (such as load differences and varying degrees of aging) can lead to uneven local temperatures. Without effective inter-cluster thermal isolation and temperature control, heat can accumulate inside the container, potentially causing thermal runaway and affecting battery life and safety. Traditional temperature control methods (such as integrated air conditioning) struggle to achieve precise control for each battery cluster; therefore, a highly efficient inter-cluster temperature control structure is needed to improve the safety and reliability of energy storage systems. Utility Model Content

[0003] The purpose of this invention is to provide an inter-cluster isolation temperature control structure for energy storage containers, which can effectively solve the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] A heat-insulating airbag is installed between the battery clusters inside the container; wherein, the heat-insulating airbag is connected to an air guide pipe and an air delivery pipe with valves, the air guide pipe is supplied with air by a first air pump, and the air delivery pipe is evacuated by a second air pump.

[0006] Furthermore: the heat insulation airbag has a multi-layer structure, with the outer layer made of high-temperature resistant silicone or ceramic fiber fabric and the inner layer being a heat insulation film; and the heat insulation airbag is equipped with a first temperature sensor for detecting the temperature inside the airbag and a pressure sensor for detecting the air pressure inside the airbag.

[0007] Furthermore: the container is provided with two parallel first partitions, which divide the container into a processing space and an installation space located on the front and rear sides of the processing space; the installation space is provided with a plurality of second partitions, which are perpendicular to the first partitions, and the second partitions cooperate with the container wall to divide the installation space into multiple independent spaces, the battery cluster is disposed in the independent spaces, and the heat insulation airbags are disposed on both sides of the second partitions.

[0008] Furthermore, the second partition is also provided with a limiting strip to restrict the range of the heat insulation airbag's inflation. The limiting strip includes two connecting rods fixed to the second partition, and the connecting rods are located in front of and behind the heat insulation airbag. A limiting rod is provided on one side of the connecting rod.

[0009] Furthermore: the processing space is provided with an input pipe and an output pipe, one end of the input pipe is connected to the first air pump, and the output pipe is connected to the second air pump; the input pipe is connected to the air guide pipe, and the output pipe is connected to the air supply pipe.

[0010] Furthermore, the processing space is also equipped with an integrated air duct, which is connected to the independent space via a connecting pipe, and a cooling fan is connected to one end of the integrated air duct.

[0011] Furthermore, a second temperature sensor is installed in each of the independent spaces, and an independent emergency fan is installed in each of the independent spaces, with the emergency fan installed on the container wall.

[0012] The beneficial effects are:

[0013] By placing heat-insulating airbags between battery clusters and utilizing their multi-layered high-temperature resistant materials, heat transfer between adjacent battery clusters is effectively blocked. Compared to traditional integrated air conditioning cooling methods, this invention can specifically prevent the spread of localized high temperatures and avoid heat accumulation problems caused by differences in operating conditions, thereby significantly reducing the risk of thermal runaway.

Compared to traditional overall heat dissipation, this design not only improves heat dissipation efficiency but also enables rapid response in the event of an anomaly in a particular battery cluster, preventing heat from spreading to other areas and enhancing the system's safety and stability.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] See Figure 1-5 This is one embodiment of the energy storage container cluster-to-cluster isolation temperature control structure of this utility model, used to achieve thermal isolation and efficient temperature control between battery clusters within an energy storage container. This structure, by placing heat-insulating airbags between battery clusters and combining them with a zoned design, airflow regulation, and a temperature monitoring system, effectively prevents heat accumulation inside the container, thereby improving battery safety and lifespan.

[0028] The energy storage container 1 houses multiple battery clusters 2, each composed of several battery modules. To achieve thermal isolation between clusters, heat-insulating airbags 3 are installed between adjacent battery clusters 2. The heat-insulating airbags 3 are connected to a first air pump 6 and a second air pump 7 via air guide pipes 4 and air delivery pipes 5, respectively, forming a dynamically adjustable inflation and deflation system. In addition, the interior of the container 1 is divided into independent installation spaces 12 and processing spaces 11 by partitions, and is equipped with temperature control and emergency cooling devices to ensure the independence and stability of the operating environment of each battery cluster 2.

[0029] The heat-insulating airbag 3 is the core component of this structure, used to form a physical and thermal isolation barrier between the battery clusters 2. The heat-insulating airbag 3 adopts a multi-layer structure design; its outer layer is made of high-temperature resistant silicone or ceramic fiber fabric, capable of withstanding the high-temperature environment that may be generated during battery operation; the inner layer is a heat-insulating film, further reducing heat conduction. To monitor the working status of the airbag in real time, each heat-insulating airbag 3 is equipped with a first temperature sensor 8 and a pressure sensor 9. The first temperature sensor 8 is used to detect the internal temperature of the airbag, and the pressure sensor 9 is used to monitor the air pressure inside the airbag, ensuring that it remains within the designed operating range.

[0030] Simultaneously, based on the data of the heat insulation airbag 3 detected by the first temperature sensor 8 and the air pressure sensor 9, the first air pump 6 and the second air pump 7 can be used to guide and extract air to achieve dynamic balance of temperature control.

[0031] For example, if the battery clusters inside the heat insulation airbag 3 emit too much heat and the temperature reaches a threshold, the first air pump 6 and the second air pump 7 will work together to replace the hot gas inside the heat insulation airbag 3.

[0032] The heat-insulating airbag 3 is connected to an external air pump system via an air duct 4 and an air delivery pipe 5. The air duct 4 is supplied with air by a first air pump 6 to inflate the airbag, filling the gaps between the battery clusters 2. The air delivery pipe 5 is evacuated by a second air pump 7 to expel gas from the airbag when needed, regulating its volume and pressure. Both the air duct 4 and the air delivery pipe 5 are equipped with valves for precise control of airflow direction and flow rate.

[0033] Internal space partitioning of the container:

[0034] The energy storage container 1 utilizes a well-planned interior space to achieve independent installation and temperature control of the battery clusters 2. Specifically, the container 1 is divided into three areas by two parallel first partitions 10: a central processing space 11, and two installation spaces 12 located on either side of the processing space 11. The installation spaces 12 are used to house the battery clusters 2, while the processing spaces 11 accommodate the piping and equipment for the temperature control system.

[0035] Within each installation space 12, several second partitions 13 are further provided. The second partitions 13 are perpendicular to the first partition 10 and work in conjunction with the container wall 1 to divide the installation space 12 into four independent spaces 14. Each independent space 14 houses a battery cluster 2, and heat-insulating airbags 3 are positioned on both sides of the second partition 13, isolating the battery clusters 2 in adjacent independent spaces 14. This design ensures that the heat generated by each battery cluster 2 during operation is not directly transferred to adjacent areas.

[0036] Thermal insulation airbag 3 limiting and support structure:

[0037] To ensure that the heat insulation airbag 3 can stably fill the designated area without excessive displacement during inflation, a limiting strip 15 is provided on the second partition 13. The limiting strip 15 includes two connecting rods 151 and one limiting rod 152. The connecting rods 151 are fixed to the second partition 13 and are located at the front and rear of the heat insulation airbag 3, respectively. The limiting rod 152 is connected to one side of the connecting rods 151, forming a semi-enclosed structure. This design limits the inflation range of the heat insulation airbag 3, making it fit tightly against the gap between the battery clusters 2, while avoiding interference with other components.

[0038] Piping and heat dissipation design of the temperature control system:

[0039] The processing space 11, as the core area of ​​the temperature control system, contains an input pipe 16, an output pipe 17, and an integrated air duct 18. One end of the input pipe 16 is connected to the first air pump 6, and the other end is connected to the air guide pipe 4, used to supply gas to the heat insulation airbag 3. One end of the output pipe 17 is connected to the second air pump 7, and the other end is connected to the air supply pipe 5, used to discharge gas from the heat insulation airbag 3. Through the coordinated operation of the first air pump 6 and the second air pump 7, the inflation and deflation process of the heat insulation airbag 3 can be dynamically adjusted to adapt to the thermal insulation requirements under different operating conditions.

[0040] In addition, an integrated air duct 18 is provided within the processing space 11 to provide cooling airflow to the independent spaces 14. The integrated air duct 18 is connected to each independent space 14 via a connecting pipe 21, with one end connected to a cooling fan 19. When the cooling fan 19 is running, it introduces external cool air into the integrated air duct 18 and distributes it to each independent space 14 via the connecting pipe 21, carrying away the heat generated by the battery cluster 2 during operation.

[0041] Temperature monitoring and emergency heat dissipation:

[0042] To achieve precise monitoring of the operating environment of each battery cluster, a second temperature sensor is installed in each independent space 14 to detect the temperature around the battery cluster 2 in real time. When the temperature in an independent space 14 exceeds a safety threshold, the system can reduce the temperature by adjusting the speed of the cooling fan 19 or increasing the airflow.

[0043] As a further safety precaution, each independent space 14 is also equipped with an independent emergency fan 20. The emergency fan 20 is installed on the wall of the container 1. When a certain battery cluster 2 experiences abnormal high temperature or thermal runaway risk, it can be started independently to quickly exhaust hot air outside the container and prevent heat from spreading to other areas.

[0044] In actual operation, the workflow of this energy storage container cluster-isolated temperature control structure is as follows:

[0045] Normal operation: The first air pump 6 inflates the heat insulation airbag 3 through the input pipe 16 and the air guide pipe 4, causing it to expand and form a thermal insulation barrier between the battery clusters 2. The cooling fan 19 provides stable cool air to the independent space 14 through the integrated air duct 18, maintaining the normal operating temperature of the battery clusters 2.

[0046] In case of abnormal temperature: If the second temperature sensor detects an increase in temperature in a certain independent space 14, the system increases the speed of the cooling fan 19, or adjusts the air pressure of the heat insulation airbag 3 through the second air pump 7 to enhance the isolation effect.

[0047] Emergency situation: If a battery cluster 2 shows signs of thermal runaway, the emergency fan 20 will start to quickly expel the high-temperature gas, while the heat insulation airbag 3 will maintain the isolation of the adjacent area to prevent the accident from escalating.

[0048] Through the above design, the present invention achieves effective thermal isolation and precise temperature control between battery clusters 2, significantly reduces the risk of thermal runaway, extends battery life, and improves the overall safety of energy storage container 1.

[0049] This specific embodiment provides a temperature control structure for an energy storage container 1 based on a heat-insulating airbag 3 and a partitioned design. Combined with dynamic airflow regulation and multi-level temperature monitoring, it meets the requirements of modern energy storage systems for efficient heat dissipation and safe operation.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
