The container body includes a plurality of energy storage compartments and quick-connect compartments arranged continuously along a first direction. The energy storage compartments are used to house battery clusters. The quick-connect compartment includes a bulkhead and a door. A quick-connect plug is provided on the door. The quick-connect plug includes an inner end located inside the quick-connect compartment and an outer end extending outside the door. Since the outer end extends outside the door, in actual use, there is no need to open the door.

[0029] With the rapid development of technology, electricity has become an indispensable energy source in people's production and daily life. To improve the smoothness of electricity supply and ensure the normal operation of production and daily life, energy storage devices are needed. As devices that cyclically store and release electrical energy, energy storage devices store electrical energy or supply the stored energy to electrical devices through charging or discharging. Energy storage devices are widely used in industrial power supply, household power supply, temporary power supply, mobile power supply, wind power generation, solar power generation, and energy storage power stations.

[0030] Energy storage devices can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems, or temporary power supply systems. Energy storage power stations can store electrical energy during off-peak hours and provide power to users or electrical equipment during peak hours. Wind power generation systems collect wind energy from wind turbines, convert it into electricity, and then store it in energy storage devices. Solar power generation systems convert solar energy into electricity, store it in energy storage devices, and supply it to users as needed. Mobile power systems can power equipment in areas inaccessible by the mains grid, such as remote mountainous areas and isolated wilderness areas. Temporary power supply systems can provide power to users when there is insufficient electricity.

[0031] Containerized energy storage system (referred to as "energy storage container") is a new type of energy storage device. The energy storage container is an integrated and modular energy storage solution that integrates core components such as battery packs, battery management systems, energy conversion systems, temperature control systems, and fire protection systems into a standardized container to realize the storage and dispatch of electrical energy.

[0032] Its core components include at least:

[0033] Battery clusters (also known as "battery packs") typically use lithium-ion batteries (such as lithium iron phosphate), lead-acid batteries, or flow batteries, with energy density, lifespan, and cost selected according to requirements.

[0034] Battery Management System: Monitors battery status (voltage, temperature, remaining charge, etc.) to ensure safe operation and prevent overcharging / over-discharging.

[0035] Energy conversion system: Enables bidirectional conversion between DC (battery) and AC (grid), and supports charge and discharge control.

[0036] Temperature control system: Air conditioning or liquid cooling device to maintain the battery within the optimal operating temperature range (e.g., 15-30°C).

[0037] Fire protection system: Enables gas extinguishing (such as heptafluoropropane) or liquid extinguishing, smoke detection, etc., to ensure fire safety.

[0038] In practical applications, after the energy storage container is transported to the site, the wiring harness inside the container needs to be connected to external wiring harnesses to achieve power transmission, signal interaction, and system control. For example, by connecting to external high-voltage wiring harnesses, the energy storage container can be connected to the power grid or load, enabling bidirectional energy flow between DC (battery) and AC (power grid / electrical equipment) through an energy conversion system. Alternatively, by connecting to communication wiring harnesses (such as CAN bus, fiber optics), data such as battery status (remaining charge, temperature, voltage) and fault alarms can be transmitted to monitoring and data acquisition systems or cloud platforms. Or, by connecting to grounding wiring harnesses, the energy storage container can be connected to the grounding grid to prevent damage from leakage or lightning strikes.

[0039] Connecting existing energy storage containers to external wiring harnesses is time-consuming and labor-intensive. It requires opening the container door and using a special torque wrench to connect the wiring harnesses inside the container to the external wiring harnesses. Wiring is difficult, and maintenance and disassembly are also difficult. It requires opening the container door and then having professionals use specialized tools for maintenance and disassembly. Therefore, how to conveniently and quickly perform on-site installation and wiring has become an urgent problem to be solved.

[0040] Based on this, this application provides an energy storage container.

[0041] Figure 1 This illustration shows a structural diagram of an energy storage container containing battery clusters, according to an embodiment of this application. Figure 2 This diagram illustrates the structure of an energy storage container without battery clusters, according to an embodiment of this application. Figure 3 A side view of an energy storage container according to an embodiment of this application is shown. Figure 4 A schematic diagram of the structure of the hatch and quick-connect plug according to an embodiment of this application is shown.

[0042] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the energy storage container includes: a container body 100, which includes a plurality of energy storage compartments 150 and a quick-connect compartment 120 arranged continuously along a first direction. The energy storage compartments 150 are used to accommodate battery clusters 200. The quick-connect compartment 120 includes a bulkhead 122 and a door 121. A quick-connect plug 300 is provided on the door 121. The quick-connect plug 300 includes an inner end 320 located inside the quick-connect compartment 120 and an outer end 310 extending out of the door 121. A connecting copper busbar 400 is provided inside the quick-connect compartment 120. The connecting copper busbar 400 is insulated from the bulkhead 122. The connecting copper busbar 400 includes a first connecting part 410 and a second connecting part 420. The first connecting part 410 is connected to the inner end 320, and the second connecting part 420 is used to connect to the battery clusters 200.

[0043] Specifically, the energy storage container includes a container body 100, which can be a hollow cuboid or cube structure. The container body 100 includes components along a first direction (i.e., Figure 1 Multiple energy storage compartments 150 and quick-connect compartments 120 are arranged in a continuous manner (in the direction indicated by X in the diagram). The energy storage compartments 150 are used to accommodate battery clusters 200. Each energy storage compartment accommodates at least one battery cluster 200, and the battery cluster 200 may include multiple battery packs stacked along the height direction of the housing 100.

[0044] The quick-connection compartment 120 is a hollow compartment. The quick-connection compartment 120 includes a bulkhead 122 and a door 121. The bulkhead 122 includes a top wall 1211 and two side walls 1222 located at both ends of the top wall 1211 and arranged opposite to each other. The top wall 1211, the two side walls 1222 and the door 121 together form the quick-connection compartment 120.

[0045] A quick-connect plug 300 is installed on the hatch 121. The quick-connect plug 300 can be fixed to the hatch 121 with bolts. The quick-connect plug 300 can be straight or bent, so that it can match different wiring methods of external wiring harnesses. In addition, the quick-connect plug 300 has high corrosion resistance and high UV resistance, which improves the service life of the quick-connect plug 300.

[0046] The quick-connect plug 300 includes an inner end 320 located within the quick-connect compartment 120 and an outer end 310 extending beyond the door 121. The outer end 310 is used for connection to external wiring harnesses. Since the outer end 310 extends beyond the door 121, in actual use, there is no need to open the door 121; users can directly connect the external wiring harness to the outer end 310 from outside the door 121, improving the convenience of connecting to external wiring harnesses. When it is necessary to replace or repair the external wiring harness, there is also no need to open the door 121; the replacement and repair of the external wiring harness can be carried out directly from outside the door 121, improving the convenience and speed of maintenance, and thus enhancing the usability of the energy storage container.

[0047] The quick-connect compartment 120 is equipped with a connecting copper busbar 400, which is insulated from the compartment wall 122. The connecting copper busbar 400 includes a first connecting part 410 and a second connecting part 420. The second connecting part 420 is used to connect with the battery cluster 200 to transfer power from the battery cluster 200 to the connecting copper busbar 400. The first connecting part 410 is connected to the inner end 320. Thus, the power transferred to the connecting copper busbar 400 can be sequentially transferred to the external wiring harness after passing through the first connecting part 410, the inner end 320, and the outer end 310 of the connecting copper busbar 400. In this way, the connection and power transfer between the battery cluster 200 inside the energy storage container and the external wiring harness are realized through the connection of the quick-connect plug 300 and the connecting copper busbar 400.

[0048] In this application, by installing a quick-connect plug 300 on the hatch 121, and the quick-connect plug 300 including an inner end 320 located inside the quick-connect compartment 120 and an outer end 310 extending outside the hatch 121, the external wiring harness can be connected to the outer end 310 outside the hatch 121 without opening the hatch 121, improving the convenience of connecting the energy storage container to the external wiring harness. Furthermore, the power transfer between the battery cluster 200 inside the energy storage container and the external wiring harness can be achieved simply by connecting the quick-connect plug 300 and the connecting copper busbar 400, and the quick connection between the internal and external wiring harnesses is realized, improving the convenience of external wiring harness connection and power transfer, thereby improving the ease of use of the energy storage container.

[0049] Figure 5 The illustration shows a first partial rear view of the energy storage container of this application after removing the rear door panel 170 of the container. In this application, the rear door panel 170 refers to the door panel that is connected to the hatch 121 and is disposed opposite to the front door panel 160.

[0050] See Figure 4 and Figure 5 As shown, in some embodiments, the housing 100 includes a base plate 140, and a first connecting portion 410 and a second connecting portion 420 are connected along a first direction (i.e., Figure 5 The first connecting part 410 is located near the hatch 121 in the direction shown in the middle X. In the height direction of the container 100, the distance between the second connecting part 420 and the bottom plate 140 is less than the distance between the first connecting part 410 and the bottom plate 140.

[0051] Specifically, the first connecting part 410 is located near the hatch 121, which facilitates the connection of the first connecting part 410 to the inner end 320 of the quick connector 300 provided on the hatch 121. In specific implementation, the first connecting part 410 can be connected to the inner end 320 through a conductive wire harness.

[0052] In the height direction of the box 100 (i.e. Figure 5 In the direction shown by Z, the distance between the second connecting part 420 and the base plate 140 is less than the distance between the first connecting part 410 and the base plate 140. That is, the second connecting part 420 is closer to the base plate 140 than the first connecting part 410. The heights of the first connecting part 410 and the second connecting part 420 are not the same. They are staggered in the height direction of the housing 100. In actual installation, the staggered first connecting part 410 and the second connecting part 420 provide installation space for the connection of the wire harness to the first connecting part 410 and the second connecting part 420. It also makes the wire harnesses connected to the first connecting part 410 and the second connecting part 420 staggered, providing wiring space for the wire harness.

[0053] In some embodiments, see continue to see Figure 5As shown, the connecting copper busbar 400 includes a first direction (i.e. Figure 5 The first copper busbar connection portion 430 and the second copper busbar connection portion 440 are arranged at intervals in the direction shown by X. The first copper busbar connection portion 430 is connected to the first connection portion 410, and the second copper busbar connection portion 440 is connected to the second connection portion 420. The bulkhead 122 includes a top wall 1211 and a side wall 1222. The first copper busbar connection portion 430 is insulated from the top wall 1211, and the second copper busbar connection portion 440 is insulated from the side wall 1222.

[0054] Specifically, the first copper busbar connecting portion 430 and the second copper busbar connecting portion 440 are along the first direction (i.e., Figure 5 The copper busbar connecting parts 430 and 440 are spaced apart in the direction shown in the middle X, so that there is a certain gap between the first copper busbar connecting part 430 and the second copper busbar connecting part 440, which facilitates the connection and installation of the first connecting part 410 and the first copper busbar connecting part 430, and the second connecting part 420 and the second copper busbar connecting part 440.

[0055] In practice, the first connecting part 410 and the first copper busbar connecting part 430 can be connected by bolts, and the second connecting part 420 and the second copper busbar connecting part 440 can also be connected by bolts. The bolt connection method facilitates quick installation and quick disassembly and replacement, increasing the ease of use of the connecting copper busbar 400.

[0056] The first copper busbar connection 430 is insulated from the top wall 1211, and the second copper busbar connection 440 is insulated from the side wall 1222. This achieves an insulated connection between the connecting copper busbar 400 and the bulkhead 122 of the quick-connect compartment 120, ensuring that there is no direct contact between the connecting copper busbar 400 and the bulkhead 122, avoiding short circuits in the connecting copper busbar 400, and thus avoiding power transmission failures caused by short circuits.

[0057] In some embodiments, see continue to see Figure 5 The connecting copper busbar 400 also includes a middle part 450, which is connected to both the first copper busbar connecting part 430 and the second copper busbar connecting part 440, and there is a gap between the middle part 450 and the bulkhead 122.

[0058] Specifically, the intermediate part 450 is connected to both the first copper busbar connecting part 430 and the second copper busbar connecting part 440. The intermediate part 450 serves to connect the first copper busbar connecting part 430 and the second copper busbar connecting part 440, so that the first copper busbar connecting part 430 and the second connecting part 420 can be connected through the intermediate part 450, and there is a certain gap in the first direction, which facilitates actual installation and use.

[0059] There is a gap between the intermediate part 450 and the bulkhead 122, so that the intermediate part 450 and the bulkhead 122 do not directly contact each other, thus avoiding a short circuit in the intermediate part 450 caused by direct contact between the intermediate part 450 and the bulkhead 122, which in turn would cause a short circuit in the entire connecting copper busbar 400.

[0060] Figure 6 This illustration shows a second partial rear view of the energy storage container according to an embodiment of this application, with the rear door panel 170 of the container removed. Figure 7 A partial schematic diagram of the connecting copper busbar 400 according to an embodiment of this application is shown.

[0061] In some embodiments, see Figure 6 and Figure 7 As shown, the quick-connect compartment 120 is also provided with a first fixing member 600 and a second fixing member 500. The first copper busbar connection part 430 is insulatedly connected to the top wall 1211 through the first fixing member 600, and the second copper busbar connection part 440 is insulatedly connected to the side wall 1222 through the second fixing member 500.

[0062] Specifically, all or part of the first fastener 600 and the second fastener 500 are made of insulating material. At least, the portion of the first fastener 600 connected to the top wall 1211 and the portion of the second fastener 500 connected to the side wall 1222 are made of insulating material, ensuring that the first copper busbar connection 430 connected to the top wall 1211 via the first fastener 600 is insulated from the top wall 1211. Similarly, it is also ensured that the second copper busbar connection 440 connected to the side wall 1222 via the second fastener 500 is insulated from the side wall 1222, ensuring that the entire connecting copper busbar 400 is insulated from the bulkhead 122, thus preventing short circuits in the connecting copper busbar 400.

[0063] In some embodiments, see continue to see Figure 6 and Figure 7 As shown, the first fixing member 600 includes an insulating horizontal plate 610 extending along the first direction and an insulating vertical plate 620 extending along the height direction. The first copper busbar connecting part 430 is connected to the insulating horizontal plate 610 through the insulating vertical plate 620. The insulating horizontal plate 610 is connected to the top wall 1211.

[0064] Specifically, the insulating horizontal plate 610 extends along the first direction, and the insulating vertical plate 620 is connected to the end of the insulating horizontal plate 610 away from the hatch 121. The first copper busbar connection part 430 is also connected to the insulating vertical plate 620. Thus, the arrangement of the insulating horizontal plate extending along the first direction increases the connection area between the insulating horizontal plate 610 and the top wall 1211, which facilitates the connection and fixation of the insulating horizontal plate 610 and the top wall 1211. On the other hand, it increases the distance between the insulating vertical plate 620, the first copper busbar connection part 430 connected to the insulating vertical plate 620, the first connection part 410 connected to the first copper busbar connection part 430, and the hatch 121. This provides installation space for the connection and installation of the first connection part 410 and the wiring harness, and also provides wiring space for the wiring harness connected to the first connection part 410.

[0065] The insulating vertical plate 620 extends along its height, thus increasing the connection area between the insulating vertical plate 620 and the first copper busbar connection part 430, facilitating their connection and fixation, and ensuring a firm connection. In practice, the insulating vertical plate 620 and the first copper busbar connection part 430 can be connected by bolts. Bolt connection facilitates quick installation, as well as quick disassembly and replacement, increasing the convenience of connection between the connecting copper busbar 400 and the first fixing member 600, and also facilitating subsequent replacement of the connecting copper busbar 400.

[0066] Furthermore, both the insulating horizontal plate 610 and the insulating vertical plate 620 are made of insulating material to ensure that the first fixing member 600 and the top wall 1211, as well as the first fixing member 600 and the connecting copper busbar 400 are insulated connections, thus ensuring the safety of the connecting copper busbar 400.

[0067] In some embodiments, see continue to see Figure 6 and Figure 7 As shown, the second fixing member 500 includes an insulator 510 and a fixing plate 520. The second copper busbar connection part 440 is connected to the fixing plate 520 through the insulator 510, and the fixing plate 520 is connected to the side wall 1222.

[0068] Specifically, the insulator 510 is made of insulating material and is connected to the second copper busbar connection part 440. The insulator 510 is also connected to the side wall 1222 via the fixing plate 520, thus ensuring that the second copper busbar connection part 440 and the side wall 1222 are insulated and ensuring the safety of the second copper busbar connection part 440 and the entire connecting copper busbar 400.

[0069] The fixing plate 520 can be made of insulating material or non-insulating material. For example, the fixing plate 520 can be made of metal. When the fixing plate 520 is made of non-insulating material, the connection and installation of the fixing plate 520 made of non-insulating material with the side wall 1222 made of metal material is more convenient and easier to operate.

[0070] Insulator 510 along the first direction (i.e. Figure 6 The direction (indicated by X) extends so that there is a certain distance between the second copper busbar connection part 440 connected to the insulator 510 and the fixing plate 520, providing installation space for the connection and installation between the second copper busbar connection part 440 and the insulator 510, as well as the connection and installation between the second copper busbar connection part 440 and the first connection part 410, which facilitates the operation of the operator.

[0071] In some embodiments, see continue to see Figure 5 and Figure 6 As shown, the housing 100 includes a base plate 140 and a connecting copper busbar 400 with a U-shaped structure. The opening of the U-shaped structure faces the base plate 140, and the two ends of the U-shaped structure are a first connecting part 410 and a second connecting part 420, respectively.

[0072] Specifically, the opening of the U-shaped structure faces the base plate 140, which facilitates the operator to pass through the opening to connect and install the first connecting part 410 with the first copper busbar connecting part 430, and the first copper busbar connecting part 430 with the insulating vertical plate 620. It also facilitates the connection and installation of the second connecting part 420 with the second copper busbar connecting part 440, and the second copper busbar connecting part 440 with the insulator 510. This provides space for the connection and installation of various components and improves the overall ease of operation.

[0073] The two ends of the U-shaped structure are a first connecting part 410 and a second connecting part 420, respectively. Both the first connecting part 410 and the second connecting part 420 are located close to the base plate 140, which makes it convenient for operators to connect and install the first connecting part 410 to the inner end 320 through a wiring harness. It also makes it convenient for operators to connect the second connecting part 420 to the battery cluster 200 through a wiring harness, improving operational flexibility. At the same time, the fact that the first connecting part 410 and the second connecting part 420 are both located close to the base plate 140 can also reduce the length of the connecting wiring harness used, saving assembly costs.

[0074] In some embodiments, see continue to see Figure 1 and Figure 3 As shown, the container 100 includes a base plate 140, and a hatch 121 is detachably and / or rotatably connected to the base plate 140. This facilitates the opening and closing of the hatch 121, as well as its installation and replacement. For example, a hinge structure is provided on the side of the hatch 121 closest to the base plate 140 to achieve a rotatable connection between the hatch 121 and the base plate 140. A door lock is provided on the side of the hatch 121 furthest from the base plate 140, which connects the hatch 121 to a door panel located above the hatch 121, thereby locking the hatch 121.

[0075] This energy storage container can achieve both quick-connect and non-quick-connect connections. When quick-connect connection is not needed, the hatch 121 can be blocked or a new door panel without quick-connect plug 300 can be made to switch to non-quick-connect connection.

[0076] In some embodiments, see continue to see Figure 1 and Figure 3 The energy storage container also includes an electrical compartment 110, which is located on the same side of multiple energy storage compartments 150 and arranged along the height direction of the container body 100. The container body 100 includes a bottom plate 140. The electrical compartment 110 is located on the side of the quick-connect compartment 120 away from the bottom plate 140. The electrical compartment 110 is used to accommodate at least one electrical component 111.

[0077] Specifically, the electrical compartment 110 is used to house at least one electrical component 111, which may be at least one of a distribution box, a main control box, a fire control box, a fan, and an air conditioner.

[0078] The electrical compartment 110 and the quick-connect compartment 120 are located on the same side of the multiple energy storage compartments 150 and arranged along the height direction of the container 100. Thus, in the first direction, the electrical compartment 110 does not occupy additional internal space of the container 100, improving the space utilization rate inside the container 100. With a fixed size for the container 100, the electrical compartment 110's arrangement, without occupying additional internal space, effectively increases the space of the energy storage compartments 150 within the container 100. This allows the energy storage compartments 150 to accommodate more battery clusters 200, increasing the energy density of the energy storage container.

[0079] The electrical compartment 110 is located on the side of the quick-connect compartment 120 away from the base plate 140. Thus, the electrical compartment 110 is located above the quick-connect compartment 120, and the quick-connect compartment 120 is located on the side closer to the base plate 140. This facilitates the connection of the outer end 310 of the quick-connect plug 300 provided on the door 121 of the quick-connect compartment 120 with the external wiring harness, while also reducing the length of the wiring in the field and making it easier for operators to operate.

[0080] In some embodiments, see continue to see Figure 1 and Figure 3 The energy storage container also includes a liquid-cooled compartment 130, which is connected to the electrical compartment 110 along a second direction (i.e., Figure 1 The second direction (as shown in the Y direction) is arranged in a liquid cooling chamber 130, which is equipped with a liquid cooling component 131. The liquid cooling component 131 is used for heat exchange with the battery cluster 200 in the energy storage chamber 150. The second direction is opposite to the first direction (i.e., Figure 1 (The direction indicated by X in the diagram) is perpendicular.

[0081] Specifically, the liquid cooling compartment 130 and the electrical compartment 110 are along the second direction (i.e. Figure 1 The arrangement (in the direction shown by Y) is exemplarily such that the second direction can be the width direction of the box 100, and the first direction can be the length direction of the box 100.

[0082] Since the liquid cooling compartment 130 and the electrical compartment 110 are arranged along the second direction, the liquid cooling compartment 130 does not occupy additional internal space of the container 100 in the first direction. The liquid cooling compartment 130, the electrical compartment 110, and the quick-connect compartment 120 share a single space, improving the space utilization rate inside the container 100. Given a fixed size for the container 100, the fact that the liquid cooling compartment 130 does not occupy additional internal space effectively increases the space of the energy storage compartment 150 within the container 100. This allows the energy storage compartment 150 to accommodate more battery clusters 200, increasing the energy density of the energy storage container.

[0083] The liquid cooling chamber 130 is equipped with a liquid cooling component 131, which is used to exchange heat with the battery cluster 200 in the energy storage chamber 150 to ensure that the temperature of the battery cluster 200 can be controlled at a suitable operating temperature (e.g., 15-30°C). For example, the liquid cooling component 131 can be a liquid cooling pipe or a liquid cooling plate, etc.

[0084] Furthermore, the electrical compartment 110, quick-connect compartment 120, and liquid-cooled compartment 130 are all isolated from each other and are not connected to each other, ensuring the safety of each compartment. For example, firewalls or insulating panels can be installed between the electrical compartment 110, quick-connect compartment 120, and liquid-cooled compartment 130 to provide heat insulation and fire prevention, thereby improving the safety of the energy storage system.

[0085] Furthermore, the container 100 can adopt a standard container structure (such as a standard 20-foot shipping container) and can be used directly as a transport container, eliminating the need to set up a separate transport container on the outside of the energy storage container. This helps to increase carrying capacity and reduce transportation costs. Standard lifting corners are provided on the top and bottom of the container for easy lifting.
