Energy storage batteries have the advantages of high efficiency, good dynamic characteristics, long service life, and are almost unaffected by terrain. They are widely used in energy storage power stations, battery swap stations and other scenarios.

[0003] The battery modules in the energy storage system are mainly fixed at the bottom. However, due to the heavy weight of the battery modules, they will inevitably shake and vibrate during loaded transportation. When they are mechanically damaged by impact, extrusion, etc., the battery modules will be squeezed and deformed, and collide with each other, causing extrusion damage to the energy storage cells, triggering thermal runaway of the energy storage battery, and chemical reactions between its internal materials to release heat, causing safety accidents. There are great risks in transportation.

[0004] Therefore, in order to solve the above problems, it is necessary to develop an energy storage system battery pack operation storage cabin. Utility Model Content

[0027] The technical solution of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 、 Figure 2 As shown, a battery pack operating storage cabin for an energy storage system includes a cabin body 1, wherein a plurality of storage units 2 for placing battery modules are arranged in the middle of the cabin body 1 and separated by horizontal partitions 101 and vertical partitions 102, and buffer chambers 3 formed by the vertical partitions 102 and the side walls of the cabin body 1 are arranged on both sides of the cabin body 1, and a charging and discharging unit 4 is arranged in the buffer chamber 3.

[0029] In which, the storage unit 2 includes a fixed bracket 201 arranged on the lower horizontal partition 101, and an elastic buffer airbag 202 arranged at the bottom end of the upper horizontal partition 101. The bottom end of the elastic buffer airbag 202 is fixedly provided with an inverted concave limiting plate 203. The limiting plate 203 and the fixed bracket 201 together form a storage space 204 for storing the battery module. Preferably, a pressure sensor 206 is provided on the top surface of the limiting plate 203 that abuts the battery module. The pressure sensor 206 is provided to monitor the tightness of the abutment between the limiting plate 203 and the battery module, so as to facilitate the control of the inflation and deflation degree of the elastic buffer airbag 202; preferably, a buffer pad is provided on the inner side surface of the limiting plate 203. By providing a buffer pad on the side of the limiting plate 203 that contacts the battery module, further protection is provided to the battery module to avoid damage.

[0030] Wherein, the inflation and deflation holes 2021 of the elastic buffer airbag 202 are connected to the inflation and deflation unit 4 arranged in the buffer chamber 3 through the connecting pipe 205; preferably, in order to realize the function of automatic exhaust of the elastic buffer airbag 202, a return spring can be arranged inside the elastic buffer airbag 202. By arranging the return spring inside the elastic buffer airbag 202, the elastic force of the return spring to restore its original shape after use can be used to prompt the elastic buffer airbag 202 to squeeze and discharge the gas inside it, thereby realizing the function of automatic exhaust. It should be noted that the return spring should be in a stretched state when inflating. After inflation is completed, when exhaust is required, the exhaust pipe is opened. As the gas is discharged, the force applied to the return spring becomes smaller and smaller. At the same time, the elastic force of the return spring to restore its original shape further prompts the elastic buffer airbag 202 to squeeze and discharge the gas inside it; or, the elastic buffer airbag The top and bottom of the bag 202 are fixedly connected to the transverse partition 101 and the limit plate 203 by the support plate 2022 respectively. A corresponding reset adsorption magnet 2023 is provided between the two support plates 2022. Initially, the reset adsorption magnet 2023 is in the adsorption state. When the elastic cushioning airbag 202 is inflated, the elastic cushioning airbag 202 gradually expands, pushing the support plate 2022 and the limit plate 203 connected to the limit plate 203 to move downward together. When the downward thrust is greater than the adsorption force, the reset adsorption magnet 2023 separates, and the limit plate 203 abuts against the battery module. After use, the exhaust pipe is opened. As the gas is discharged, the thrust exerted on the limit plate 203 and the support plate 2022 gradually decreases and is less than the adsorption force. The reset adsorption magnet 2023 resumes the adsorption state, further prompting the elastic cushioning airbag 202 to squeeze and discharge the gas inside it.

[0031] Among them, the inflation and deflation unit 4 includes an inflation pipe 401 and an exhaust pipe 402 arranged in the buffer chamber 3, the inflation pipe 401 and the exhaust pipe 402 are respectively connected to the connecting pipe 205, and the inflation pipe 401 is connected to an inflation pump 403. Preferably, the inflation pump 403 is set to one or more, or the number of the inflation pumps 403 is adapted to the number of storage units 2, so as to facilitate individual control and be more convenient to use; preferably, a control valve 404 is respectively provided on the inflation pipe 401 and the exhaust pipe 402, and the inflation pipe 401 and the exhaust pipe 402 are connected or not by opening and closing the control valve 404, so as to realize the switching between the inflation mode and the exhaust mode; preferably, a vent 301 is provided on the outer wall of the buffer chamber 3, and a filter 302 is provided at the vent 301.

[0032] Preferably, it also includes a controller and a driving power supply arranged on the cabin 1, and the controller and the driving power supply are electrically connected to the pressure sensor 206 of the storage unit 2 and the inflation pump 403 and the control valve 404 of the inflation and deflation unit 4. It should be noted that the controller, driving power supply, pressure sensor 206, inflation pump 403 and control valve 404 and their specific circuit connection structures all belong to the existing technology and are common knowledge to those skilled in the art. No other special requirements are made in this application. It is only necessary that they can realize the functions described in this application, so no specific limitations are made here.

[0033] During the specific implementation of the present invention, when inflation is required, the control valve 404 on the exhaust pipe 402 is closed, the control valve 404 on the inflation pipe 401 is opened, and the inflation pump 403 is started to inflate the elastic buffer airbag 202. During the inflation process, the elastic buffer airbag 202 pushes the limit plate 203 to move downward until the limit plate 203 is tightly abutted against the battery module. The inflation pump 403 and the control valve 404 on the inflation pipe 401 are closed to keep the elastic buffer airbag 202 in an inflated state. When exhaust is required, the control valve 404 on the exhaust pipe 402 is opened, and the gas is discharged from the exhaust pipe 402. The elastic buffer airbag 202 squeezes and discharges the gas under the action of the reset spring or the reset adsorption magnet, and the control valve 404 on the exhaust pipe 402 is closed.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
