[0034] To describe in detail the technical content, achieved purpose and effects of the present utility model, the following is described in conjunction with the implementation manner and with reference to the drawings.

[0035] Please refer to Figures 1 to 8 , the present utility model relates to an energy storage container, which includes a box body 1. A plurality of intermediate partition walls are provided in the box body 1. The plurality of intermediate partition walls divide the inner cavity of the box body 1 into at least a first equipment compartment, a battery compartment 2 and a second equipment compartment. A PCS 9, a transformer cabinet 8 and a control cabinet 10 are provided in the first equipment compartment. The PCS 9 is electrically connected to the transformer cabinet 8 and the control cabinet 10 respectively; a plurality of water-cooled electrical cabinets 7 are provided in the battery compartment 2. Each water-cooled electrical cabinet 7 is provided with a battery pack 18. The battery pack 18 is electrically connected to the PCS 9 and the control cabinet 10.

[0036] As can be seen from the above description, the beneficial effect of the present utility model is that: a plurality of intermediate partition walls are provided in the cavity of the energy storage container, and the inner cavity of the box body is divided into a plurality of compartments, such as a first equipment compartment, a battery compartment and a second equipment compartment, by the intermediate partition walls. On this basis, devices such as a PCS, a transformer cabinet and a control cabinet are provided in the first equipment compartment, and a plurality of battery packs are provided in the battery compartment. Thus, the above devices are isolated by the intermediate partition walls (i.e., compartments), and are connected by the above devices to realize corresponding power distribution and voltage transformation functions, so as to obtain an energy storage container that can realize isolation voltage transformation and power distribution functions.

[0037] Furthermore, in the energy storage container of the present utility model, it further includes a fire outlet 4, a ventilation passage 27 and a fire inlet 28. The fire outlet 4 is provided on the box body 1. One end of the ventilation passage 27 is communicated with the battery compartment 2, and the other end is communicated with the fire outlet 4. The fire inlet 28 is provided on the wall of the battery compartment 2.

[0038] It should be noted that a corresponding gas detector 13 is also provided in the battery compartment 2, and the gas detector 13 can be a CO gas detector. In actual use, the battery compartment 2 is connected to a ventilation duct, and the ventilation duct is connected to the fire outlet 4. Since a gas detector (such as a CO gas detector) is provided in the battery compartment 2, when the CO gas detector detects the generation of CO in the battery compartment 2, the fire outlet 4 will be activated, so as to discharge the CO gas inside the battery compartment 2 out of the compartment, thus ensuring that the battery compartment 2 will not catch fire due to a high concentration of combustible gas. In addition, since the battery compartment 2 is relatively airtight, if air is exhausted from only one side, an internal and external pressure difference will be formed, making it impossible to completely exhaust the combustible gas inside the battery compartment 2. A fire inlet 28 is provided on the other side of the battery compartment 2. When the fire outlet 4 is activated, the fire inlet 28 is activated simultaneously, thus ensuring a smooth ventilation process and ensuring that the combustible gas is completely exhausted.

[0039] Furthermore, in the energy storage container of the present utility model, a first air hood 24 and a second air hood 25 are further included; the first air hood 24 is arranged on the PCS 9, and one end of the first air hood 24 is connected to the PCS 9, and the other end is connected to the louver 29 on the box body 1; the second air hood 25 is arranged on the transformer cabinet 8, and one end of the second air hood 25 is connected to the transformer cabinet 8, and the other end is connected to another louver 29 on the box body 1.

[0040] In actual application, since the PCS 9 and the transformer cabinet 8 are equipment with large heat generation and dissipate heat from the top, for this reason, a first air hood 24 and a second air hood 25 can be arranged in the first equipment compartment. Among them, one side of the first air hood 24 is connected to the top of the PCS 9 by screws, and the other side is connected to the container louver 29 by a pressing plate; similarly, one side of the second air hood 25 is connected to the top of the transformer cabinet 8 by screws, and the other side is connected to another container louver 29 by a pressing plate, so as to ensure that the heat generated inside these devices can be discharged in time, thus avoiding failures caused by excessive device temperature.

[0041] Furthermore, in the energy storage container of the present utility model, a fire extinguisher bottle, a first fire pipeline 20 and a second fire pipeline 21 are further included. The fire extinguisher bottle is arranged in the fire compartment 6 of the second equipment compartment. The fire extinguisher bottle includes a heptafluoropropane bottle 34 and a perfluoroketone bottle 35; one end of the first fire pipeline 20 is connected to the heptafluoropropane bottle 34, and the other end of the first fire pipeline 20 is connected to the battery compartment 2; one end of the second fire pipeline 21 is connected to the perfluoroketone bottle 35, and the other end of the second fire pipeline 21 is connected to the battery pack 18.

[0042] It should be noted that a fire controller 33 is also provided in the fire compartment 6, and a fire detector 14 is correspondingly provided in the battery compartment 2. The fire detector 14 can be an optoelectronic smoke fire detector. In practical applications, when the fire detector detects a fire in the battery compartment 2, the fire controller 33 controls the activation of the heptafluoropropane cylinder 34, and sprays heptafluoropropane into the battery compartment 2 through the first fire pipeline 20. At the same time, perfluoroketone is sprayed into the battery pack 18 in the water-cooled electric cabinet 7 through the second fire pipeline 21, so as to achieve double-effective fire protection for the battery compartment 2, thereby avoiding greater losses caused by the fire in the battery compartment 2.

[0043] Furthermore, in the energy storage container of the present utility model, a water-cooling unit 5 and a water-cooling pipe 22 are further included. The water-cooling unit 5 is arranged in the second equipment compartment, the water-cooling pipe 22 is arranged in the battery compartment 2, one end of the water-cooling pipe 22 is connected to the water-cooling unit 5, and the other end is connected to the battery pack 18.

[0044] As can be seen from the above description, the water-cooling unit 5 is arranged in the second equipment compartment, and the water-cooling unit 5 is installed at the bottom of the battery compartment 2. One end of the water-cooling pipe 22 is connected to the water-cooling unit 5, and the other end is connected to the battery pack 18 through the branch pipe 19. The water-cooling unit 5 and the battery pack 18 form a cooling circuit through the water-cooling pipe 22 to cool the battery pack 18 and ensure that the battery cells will not affect their service life due to excessive temperature.

[0045] Furthermore, in the energy storage container of the present utility model, a fire hydrant 16 is further included, and the fire hydrant 16 is arranged on the box body 1.

[0046] As can be seen from the above description, in some cases, if the fire in the battery compartment 2 has not been extinguished, the battery compartment 2 can be sprayed with water through the fire hydrant 16 to ensure that no greater losses will be caused when the battery compartment 2 catches fire. In practical applications, a corresponding third fire pipeline can also be set, with one end of the third fire pipeline communicating with the battery compartment 2 and the other end communicating with the fire hydrant 16, which further facilitates filling the battery compartment with water.

[0047] Furthermore, in the energy storage container of the present utility model, a plurality of brackets 26 are further included. At least one bracket 26 is arranged on the PCS, and the PCS is connected to the box body through the bracket 26. At least one bracket 26 is arranged on the transformer cabinet, and the transformer cabinet is connected to the box body through the bracket 26.

[0048] In actual application, due to the relatively weak overall strength of the wind shield, when the container is transported and lifted, the equipment cabinet will shake, causing the wind shield to break. Therefore, a first support 26 and a second support 26 are respectively added to the tops of the PCS 9 and the transformer cabinet 8, so that the PCS 9 and the transformer cabinet 8 are connected to the side wall of the container, thereby ensuring that the cabinet does not shake and further ensuring that the wind shield does not break.

[0049] Furthermore, in the energy storage container of the present utility model, a first door 3 is further included. The first door 3 is rotatably connected to the box body 1, and an air inlet hole is provided on the first door 3.

[0050] In actual use, since the heat dissipation from components such as the PCS 9 and the transformer cabinet 8 in the first equipment compartment will cause a pressure difference inside and outside the first equipment compartment, the heat dissipation effect cannot be achieved. Therefore, the present utility model opens an air inlet hole on the large door (i.e., the first door 3) of the first equipment compartment to ensure the normal heat dissipation of the equipment. On this basis, louvers and filters are installed in the air inlet hole to play a role in dust and rain prevention, ensuring the waterproof and dustproof performance of the energy storage container. In addition, it should be noted that both sides of the equipment compartment are double-opening large doors, which are convenient for equipment access and maintenance.

[0051] Furthermore, in the energy storage container of the present utility model, a lighting device 15 is further included. The lighting device 15 is arranged inside the box body 1, and the lighting device includes explosion-proof lights, emergency lights, and safety exit indicator lights.

[0052] As can be seen from the above description, a lighting device 15 is provided in the energy storage container to provide a lighting function.

[0053] Furthermore, in the energy storage container of the present utility model, a grounding copper bar 17 is provided on the box body 1, and the grounding copper bar 17 is connected to the transformer cabinet through a wire harness.

[0054] As can be seen from the above description, a grounding copper bar 17 is provided on the box body 1 to connect the grounding of each cabinet and ensure the normal grounding of each cabinet.

[0055] Please refer to Figures 1 to 8 , Embodiment 1 of the present utility model is: an energy storage container (i.e., an industrial and commercial energy storage container), which is applied to an energy storage system. This energy storage container is a standard 20-foot container, that is, the length, width, and height are 6058mm * 2438mm * 2896mm. As Figure 3As shown, the energy storage container includes a box body 1. There are two middle partition walls (i.e., the first middle partition wall 11 and the second middle partition wall 12) in the box body 1. The two middle partition walls divide the inner cavity of the box body 1 into a first equipment compartment, a battery compartment 2, and a second equipment compartment. Among them, the battery compartment 2 is arranged in the middle of the first equipment compartment and the second equipment compartment. The first middle partition wall 11 is arranged between the first equipment compartment and the battery compartment 2, and the second middle partition wall 12 is arranged between the battery compartment 2 and the second equipment compartment. Corresponding devices are provided in the first equipment compartment, the battery compartment 2, and the second equipment compartment, which will be specifically introduced below.

[0056] In this embodiment, as Figure 3 and Figure 4 shown, there are 8 water-cooled electric cabinets 7 in the battery compartment 2, and a battery pack 18 is installed on each water-cooled electric cabinet 7. In addition, a water-cooled pipe 22 is installed at the bottom of the battery compartment 2. One end of the water-cooled pipe 22 is connected to the water-cooling unit 5, and the other end is connected to the battery pack 18. The water-cooling unit 5 and the battery pack 18 form a cooling circuit through the water-cooled pipe 22 to cool the battery pack 18 and ensure that the battery cells will not affect their service life due to excessive temperature.

[0057] In addition, as Figure 4 and Figure 5 shown, a ventilation channel 27 is provided in the box body 1, and a fire outlet 4 communicating with one end of the ventilation channel 27 is opened on the box body 1 corresponding to the second equipment compartment. The gas in the battery compartment 2 can be discharged through the ventilation channel 27 and the fire outlet 4. Specifically, a receiving cavity communicating with the other end of the ventilation channel 27 is provided in the battery compartment 2, and a gas detector is provided in the receiving cavity. A fire inlet 28 is provided on the wall of the battery compartment 2 (i.e., the second middle partition wall 12), and the fire inlet 28 communicates with the receiving cavity. That is to say, a fire inlet 28 is provided on one side of the battery compartment 2, and the other side of the battery compartment 2 is connected to one end of the ventilation channel 27, and the other end of the ventilation channel 27 is connected to the fire outlet 4. Therefore, when the CO gas detector in the battery compartment 2 detects the generation of CO in the battery compartment 2, the fire outlet 4 will be activated to discharge the CO inside the battery compartment 2 out of the cabin, so as to ensure that the battery compartment 2 will not catch fire due to a high concentration of combustible gas. At the same time, since the battery compartment 2 is relatively airtight and the air is extracted outward unilaterally, an internal and external pressure difference will be formed and the combustible gas cannot be completely exhausted. By providing the fire inlet 28 on the second middle partition wall 12, when the fire outlet 4 is activated, the fire inlet 28 will be activated at the same time, so as to ensure the smoothness of the entire ventilation process and ensure the complete exhaustion of the combustible gas.

[0058] In the second equipment compartment, as Figure 6 and Figure 7As shown in the figure, there is a water-cooled unit 5 and a fire compartment 6. A third air hood 36 is installed on the top of the water-cooled unit 5, which is connected to the water-cooled unit. Through this third air hood 36, the battery compartment 2 can be dehumidified to ensure that the battery compartment 2 is dry and no condensate is generated in the battery compartment 2, avoiding affecting the normal operation of the battery. A fire controller 33, a heptafluoropropane cylinder 34, and a perfluoroketone cylinder 35 are provided in the fire compartment 6. Correspondingly, a first fire pipeline 20 and a second fire pipeline 21 are provided in the box body 1. Among them, one end of the first fire pipeline 20 is connected to the heptafluoropropane cylinder 34, and the other end of the first fire pipeline 20 is connected to the battery compartment 2. One end of the second fire pipeline 21 is connected to the perfluoroketone cylinder 35, and the other end of the second fire pipeline 21 is connected to the battery pack 18. In addition, a set of fire-fighting devices is also provided in the energy storage container. Specifically: a fire hydrant 16 is provided on the box body 1, and a third fire pipeline is also provided in the box body 1. One end of this third fire pipeline is communicated with the battery compartment 2, and the other end is communicated with the fire hydrant 16. In actual application, when the optoelectronic smoke fire detector installed in the battery compartment 2 detects that the battery compartment 2 is on fire and smoking, the internal and external audible and visual alarms of the energy storage container can be activated through the fire controller 33. At the same time, control the heptafluoropropane cylinder 34 to start, and through the first fire pipeline 20, spray heptafluoropropane on the battery compartment 2 to extinguish the fire. At the same time, the perfluoroketone cylinder 35 starts, and through the second fire pipeline 21 connected to the battery pack 18, extinguish the fire on the battery pack 18. If the fire cannot be completely extinguished at this time, the fire hydrant 16 can be controlled to start, and the battery compartment 2 can be sprayed with water to extinguish the fire through the fire hydrant 16, thus forming a triple fire protection system to ensure that no greater loss will be caused when the battery compartment 2 catches fire.

[0059] In the first equipment compartment, the middle aisle 32 of the first equipment compartment is an outdoor aisle, which divides the first equipment compartment into two. The equipment compartment is equipped with equipment cabinets, and there are various types of equipment cabinets, such as PCS 9, transformer cabinet 8, and control cabinet 10. The equipment cabinets are locked to the bottom beam of the energy storage container using M16×40 hexagon bolts with large flat washers. Since PCS 9 and transformer cabinet 8 are equipment with relatively large heat generation and both dissipate heat from the top. Therefore, the present utility model provides a first air hood 24 and a second air hood 25 in the first equipment compartment. Among them, one side of the first air hood 24 is connected to the top of PCS 9 by screws, and the other side is connected to the container louver 29 by a pressing plate; similarly, one side of the second air hood 25 is connected to the top of the transformer cabinet 8 by screws, and the other side is connected to another louver 29 of the container by a pressing plate, so as to ensure that the heat generated inside these equipment can be discharged in time, thereby avoiding failures caused by excessive equipment temperature. It should be noted that the above-mentioned louver 29 is provided with a louver assembly 30 and a filter screen 31. In addition, due to the relatively weak overall strength of the air hood, when the energy storage container is transported and hoisted, the cabinet body of the equipment cabinet will shake, resulting in the rupture of the air hood. Therefore, in order to reduce the occurrence of the above situation, the present utility model adds a first bracket 26 to the top of PCS 9 to connect PCS 9 to the side wall of the container, and adds a second bracket 26 to the top of the transformer cabinet 8 to connect the transformer cabinet 8 to the side wall of the container, so as to ensure that the cabinet body does not shake, and further ensure that the air hood does not rupture.

[0060] In this embodiment, the above-mentioned box body 1 is also provided with a first compartment door 3 (i.e., the door of the first equipment compartment) at a position corresponding to the first equipment compartment. The first compartment door 3 is a double-opening large door, and the first compartment door 3 is rotatably connected to the box body 1. By opening the first compartment door 3, the corresponding components in the first equipment compartment can be seen. In addition, as Figure 8 shown, the first compartment door 3 is provided with an air inlet hole, and the air inlet hole is provided with a louver assembly 30 and a filter screen 31. The filter screen 31 is arranged at one end of the air inlet hole close to the first equipment compartment, that is, the filter screen 31 is inside and the louver assembly 30 is outside. In actual use, through the air inlet hole on the first compartment door 3, normal heat dissipation of the first equipment compartment can be ensured. Moreover, since the air inlet hole is equipped with a louver assembly 30 and a filter screen 31, the waterproof and dustproof performance of the container can be ensured.

[0061] In addition, in the energy storage container, a lighting device 15 is also equipped. The lighting device 15 is arranged on the top of the first equipment compartment of the container, and the lighting device includes an explosion-proof lamp, an emergency lamp, and a safety exit indicator lamp. In addition, a panel switch connected to the explosion-proof lamp and several sockets are also equipped in the energy storage container. The sockets can be used to connect the emergency lamp and for backup. On the other hand, the energy storage container is also equipped with a grounding device. Specifically, a grounding copper bar 17 is included on the box body 1. The grounding copper bar 17 is connected to the ground of each cabinet through a wire harness to ensure normal grounding of each cabinet. For example, the grounding copper bar 17 is connected to the water-cooled unit 5, PCS 9, transformer cabinet 8, water-cooled electrical cabinet, etc. through a wire harness. The grounding copper bar 17 is connected to the box body 1 by M10 screws, and conductive paint is applied at the connection between the box body 1 and the copper bar to ensure grounding of the container box body 1. At the same time, one end of the grounding copper bar 17 extends out of the box body 1, and there are two M10 threaded holes at the place where the grounding copper bar 17 extends out of the box body 1 for grounding outside the container. In addition, a second compartment door 23 is provided in the above-mentioned battery compartment, and the second compartment door 23 is rotatably connected to the box body.
