[0003] In related technologies, the unreasonable design of the air inlet and outlet of energy storage containers leads to certain safety hazards. Utility Model Content

[0005] In a first aspect, embodiments of this application provide a container, including: a hatch and a frame;

[0006] The housing is fixed to the outside of the frame and forms a battery compartment for installing battery modules; at least a portion of the outer surface of the housing forms a mounting surface for installing a fan, and the mounting surface is provided with an air inlet and an air outlet communicating with the battery compartment, the air inlet being located below the air outlet.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0024] Due to the unreasonable design of the air inlet and outlet of energy storage containers in related technologies, certain safety hazards exist. Therefore, this application provides a container and an energy storage container where the air inlet is located below the air outlet. This allows cold air to be drawn in through the lower air inlet when thermal runaway occurs in the battery cell. The high-temperature flammable gas generated by the thermal runaway is then forced upwards and discharged from the upper air outlet, preventing the high-temperature flammable gas from lingering in the battery compartment and causing short circuits. Furthermore, the cold air can also cool the battery modules, improving the safety of the energy storage container and addressing existing safety hazards. Specific details are described below.

[0025] It should be noted that, in the following text, the terms “battery module,” “battery,” “battery element,” “cell,” and “battery pack” may refer to any of the various rechargeable battery chemistry and constructions, including but not limited to lithium-ion (e.g., lithium-ion phosphate, lithium cobalt oxide, lithium iron phosphate, other lithium oxide metals, etc.), lithium-ion polymer, nickel metal hydride, nickel cadmium, nickel-metal hydride, nickel-zinc, silver-zinc, or other battery types / constructions.

[0026] For details, please refer to Figure 1-2 , Figure 1 This is a three-dimensional structural diagram of a container provided in an embodiment of this application. The container 10 specifically includes a hatch and a frame 101. The hatch is fixed to the outside of the frame 101, and the hatch forms a battery compartment 102 for installing battery modules. At least a portion of the outer surface of the hatch forms a mounting surface for installing a fan. The mounting surface is provided with an air inlet 103 and an air outlet 104 communicating with the battery compartment 102. The air inlet 103 is located below the air outlet 104.

[0027] The phrase "air inlet 103 is located below air outlet 104" means that, in a direction perpendicular to the installation plane of the container, the height of air outlet 104 is higher than the height of air inlet 103. This allows the intake air to flow from bottom to top, creating an upward airflow inside the container, which can effectively carry away the high-temperature flammable gases generated by battery thermal runaway.

[0028] In this embodiment, by positioning the air inlet 103 below the air outlet 104, cold air can be drawn in through the lower air inlet 103 when thermal runaway occurs in the battery cell. This forces the high-temperature flammable gas generated by the thermal runaway upwards and expelled from the lower air outlet 104, preventing the high-temperature flammable gas from lingering in the battery compartment 102 and causing a short circuit. Furthermore, the cold air can also cool the battery module, mitigating the technical problems related to safety hazards in energy storage containers and improving their safety.

[0029] In some embodiments, the hull includes a bottom plate 201 and a top plate 202, as well as a plurality of side plates disposed between the bottom plate 201 and the top plate 202, wherein the bottom plate 201 and the top plate 202 are disposed opposite to each other.

[0030] The number of side panels can be set according to actual needs; for example, there can be three or more. Typically, there are four side panels to form a rectangular box structure. Generally, the side panels are set perpendicular to the bottom plate 201 and the top plate 202, respectively.

[0031] In some embodiments, the plurality of side panels include a first side panel 203 and a second side panel 204 disposed opposite to each other, the air inlet 103 being disposed on the first side panel 203 and the air outlet 104 being disposed on the second side panel 204.

[0032] In this embodiment, by setting the air inlet 103 on the first side plate 203 and the air outlet 104 on the second side plate 204, the air inlet 103 and the air outlet 104 can be arranged opposite each other. In addition, due to their vertical position relationship, the positions of the air inlet 103 and the air outlet 104 are diagonally arranged inside the box. In this way, the intake air can flow in a diagonal direction inside the box, that is, an airflow from bottom to top and from left to right is formed inside the box. This allows the air to pass through more battery modules inside the box, effectively promoting the gas flow inside the box and more comprehensively expelling the high-temperature flammable gas generated by the thermal runaway of the battery cells.

[0033] like Figure 3As shown, in some embodiments, the air inlet 103 and the air outlet 104 are respectively disposed diagonally opposite each other on the first side plate 203 and the second side plate 204.

[0034] Furthermore, the air inlet 103 is located at the bottom end of the first side plate 203, and the air outlet 104 is located at the top end of the second side plate 204.

[0035] In this way, the intake air can flow diagonally inside the box, forming an airflow from bottom to top, from left to right, and from front to back inside the box. This allows the air to pass through more battery modules inside the box, effectively promoting gas flow and more comprehensively expelling the high-temperature flammable gases generated by the thermal runaway of the battery cells.

[0036] In some embodiments, there are multiple air inlets 103 and multiple air outlets 104. Each air inlet 103 is located at the bottom of the first side plate 203, and each air outlet 104 is located at the top of the second side plate 204.

[0037] The number of air inlets 103 and air outlets 104 can be set according to actual needs, such as the model of the battery module or the amount of gas produced per unit time when the battery module experiences thermal runaway. The amount of gas produced per unit time is proportional to the number of air inlets 103 and air outlets 104.

[0038] In some embodiments, at least one explosion relief plate 205 is provided on the top plate 202. The number of explosion relief plates 205 may be one, two, or more, and the specific number is set according to actual needs.

[0039] The main function of the explosion relief plate 205 on the top plate 202 of the energy storage container is to release the internal pressure and flames to the external environment through directional explosion relief when the energy storage system experiences thermal runaway or fire, thereby avoiding harm to surrounding personnel and facilities.

[0040] In this embodiment, a pressure relief panel 205 is installed on top of the energy storage container. When an abnormality occurs inside the system, the pressure relief panel 205 will open, directing pressure and flames to the outside and preventing the fire from spreading to the adjacent battery compartment 102 and energy storage cabinet. This design not only helps protect the structural integrity of the energy storage system but also reduces the impact on the surrounding environment.

[0041] In some embodiments, the opening pressure and area of ​​the explosion relief plate 205 can be set according to preset explosion relief requirements to ensure that the selection and arrangement of the pressure relief outlet position can effectively address the location of the deflagration and the pressure propagation path.

[0042] In some embodiments, the explosion relief plate 205 may also be equipped with auxiliary fixing components and connecting components to enhance its stability and safety.

[0043] In this embodiment of the application, by making reasonable design and installation design of the explosion relief plate 205, the risks of fire and explosion are significantly reduced, and the safety of personnel and property is ensured.

[0044] In some embodiments, such as Figure 4 As shown, the container also includes at least one fireproof partition 206, and the shell also forms an electrical compartment 207 for installing electrical equipment. The fireproof partition 206 is disposed between the battery compartment 102 and the electrical compartment 207.

[0045] The electrical compartment 207 in the energy storage container of this embodiment is an important part of the container's interior, containing the core electrical equipment of the energy storage system. This includes, for example, distribution cabinets, PCS (Power Supply System) cabinets, fire suppression cabinets, air conditioning units, and transformer cabinets. These devices work together to achieve effective management and control of the energy storage system.

[0046] In electrical compartment 207, the PCS cabinet is one of the key components. It is responsible for switching charging and discharging modes, starting, and stopping, and provides protection functions such as input undervoltage, phase loss, and output overvoltage protection. In addition, electrical compartment 207 is also equipped with an air conditioning system to maintain the temperature and humidity within the compartment within a suitable range to ensure the normal operation of the equipment.

[0047] Electrical compartment 207 serves as the command center for the entire energy storage system, enabling monitoring and management of the entire system through communication with the BMS (Battery Management System) and other subsystems. For example, when a fire signal is detected, the heat and smoke detectors inside electrical compartment 207 will trigger alarms and initiate corresponding fire suppression measures.

[0048] The electrical compartment 207 in the energy storage container is an integrated and highly automated system that ensures the efficient and safe operation of the energy storage system by coordinating the work of various electrical devices and sensors.

[0049] In some embodiments, a raised section may be provided under the container to raise the height of the container, thereby enabling ventilation at the bottom of the container.

[0050] Furthermore, an air inlet 103 is provided on the bottom plate 201, making the position of the air inlet 103 lower, while an air outlet 104 is provided on the top plate 202, making the relative height difference between the air inlet 103 and the air outlet 104 greater, which can more effectively exhaust the high-temperature combustible gas in the box.

[0051] In some embodiments, when the air outlet 104 is disposed on the top plate 202, a rainproof device may be provided at the corresponding position of the air outlet 104 on the top plate 202 to prevent rainwater from entering the box through the air outlet 104.

[0052] Based on the same inventive concept, and building upon the aforementioned container, this application also provides an energy storage container, such as... Figure 1-4 As shown, the energy storage container includes a wind turbine (not shown), a battery module (not shown), and a container 10. The battery module is located in the battery compartment 102, and the wind turbine is located on the mounting surface.

[0053] In this embodiment, by positioning the air inlet 103 below the air outlet 104, cold air can be drawn in through the lower air inlet 103 when thermal runaway occurs in the battery cell. This forces the high-temperature flammable gas generated by the thermal runaway upwards and expelled from the lower air outlet 104, preventing the high-temperature flammable gas from lingering in the battery compartment 102 and causing a short circuit. Furthermore, the cold air can also cool the battery module, mitigating the technical problems related to safety hazards in energy storage containers and improving their safety.

[0054] In some embodiments, the fan includes an inlet fan (not shown) and / or an outlet fan (not shown), the inlet fan being installed at the air inlet 103 and / or the outlet fan being installed at the air outlet 104.

[0055] In one embodiment, the fan may include an intake fan installed at the air inlet 103.

[0056] In the above embodiments, by setting up an air intake fan and installing it at the air inlet 103, the container can actively draw in external cold air and discharge the air after it has been cooled by the battery module inside the container through the air outlet 104, which effectively promotes airflow inside the container and removes the heat from the battery module inside the container as well as the high-temperature combustible gas generated by thermal runaway.

[0057] In one embodiment, the fan may include an outlet fan installed at the outlet 104.

[0058] In the above embodiments, by setting up an exhaust fan and installing it at the air outlet 104, the air that has been cooled by the battery module inside the container can be actively discharged from the container, which can effectively promote the air flow inside the container and remove the heat from the battery module inside the container as well as the high-temperature flammable gas generated by thermal runaway.

[0059] In one embodiment, the fan includes an inlet fan and an outlet fan, the inlet fan being installed at the air inlet 103 and the outlet fan being installed at the air outlet 104.

[0060] In the above embodiments, by simultaneously setting an intake fan and an exhaust fan and installing them at the air inlet 103 and the air outlet 104 respectively (as mentioned above), the container can actively draw in external cold air and actively exhaust the air that has been cooled by the battery modules inside the container. This further promotes airflow inside the container and removes the heat from the battery modules inside the container as well as the high-temperature flammable gas generated by thermal runaway, thereby improving the stability and safety of the energy storage container.

[0061] In some embodiments, the air inlet 103 and / or air outlet 104 are provided with ventilation filters (not shown in the figure).

[0062] The model and mesh size of the ventilation filter can be set according to actual needs.

[0063] In the above embodiments, by providing ventilation filters at the air inlet 103 and / or the air outlet 104, dust and small animals can be prevented from entering, thereby improving the stability and safety of the energy storage container.

[0064] In some embodiments, the air intake fan is configured as a refrigeration air intake fan.

[0065] In the above embodiments, by configuring the air intake fan as a refrigeration air intake fan, the temperature of the outside air can be further reduced, which helps to form the required temperature difference with the gas inside the container, and can more effectively remove the gas inside the container, preventing it from lingering inside the container.

[0066] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
