[0035] The core of this application is to provide an energy storage container that reduces the size of the container while ensuring the energy density of the energy storage system.
[0036] Another core aspect of this application is to provide an energy storage system having the aforementioned energy storage container.
[0037] 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 some embodiments of this application, and not all 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.
[0038] In the field of energy storage, increasing the size of containers is often used to improve the energy density of energy storage systems. However, increasing the size of containers indefinitely will significantly increase the floor space occupied by the containers and transportation costs.
[0039] Therefore, such as Figure 1 As shown in the figure, this application discloses an energy storage container, including a container body 100. Through the independently arranged first and second row compartments 10 and 20, battery modules can be placed independently, improving the safety of the energy storage system. Simultaneously, the second row compartment 20 is divided into multiple functional zones for placing functional modules, making the layout of the functional modules more compact and improving the space utilization rate of the energy storage container. While ensuring the energy density of the energy storage system, the size of the container is reduced.
[0040] The following will combine Figures 1 to 10 The energy storage container disclosed in the embodiments of this application will be explained and described in detail.
[0041] Among them, such as Figure 1 As shown, the box 100 can adopt a cuboid structure, and the box 100 can have a first arrangement compartment 10 and a second arrangement compartment 20 arranged adjacently along its length. Simultaneously, the first arrangement compartment 10 and the second arrangement compartment 20 can be independently distributed, and the second arrangement compartment 20 forms multiple functional zones for placing functional modules, such as... Figure 2 As shown. During assembly, as... Figure 8As shown, battery modules can be placed in the first arrangement compartment 10, while multiple functional modules can be placed in their respective functional zones within the second arrangement compartment 20. This allows for independent placement of battery modules, improving the safety of the energy storage system. Furthermore, dividing the second arrangement compartment 20 into multiple functional zones for placing functional modules makes the module layout more compact, improving the space utilization of the energy storage container and reducing the container's size while maintaining the energy density of the energy storage system. It should be noted that, as... Figure 4 As shown, the functional modules may include liquid cooling unit 2221, PCS equipment (Power Conversion System, energy storage converter), fire protection device 2222, heat dissipation element, system control cabinet and customer wiring area, etc.
[0042] For example, such as Figure 2 As shown, a second partition 40 may be provided between the first arrangement compartment 10 and the second arrangement compartment 20 to separate the first arrangement compartment 10 and the second arrangement compartment 20 into two independent compartments, thereby realizing the independent setting of the battery modules and improving the safety of the energy storage system.
[0043] The energy storage container disclosed in this application has a first row of compartments 10 and a second row of compartments 20 arranged adjacent to each other along the length of the container body 100. The first row of compartments 10 and the second row of compartments 20 are arranged independently of each other, and the second row of compartments 20 forms multiple functional partitions for placing functional modules. During assembly, battery modules can be placed in the first row of compartments 10, and multiple functional modules can be placed in the respective functional partitions of the second row of compartments 20.
[0044] The energy storage container disclosed in this application embodiment allows for the independent placement of battery modules through the independently arranged first and second row compartments 10 and 20, thereby improving the safety of the energy storage system. At the same time, the second row compartment 20 is divided into multiple functional zones for placing functional modules, making the layout of the functional modules more compact and improving the space utilization rate of the energy storage container. While ensuring the energy density of the energy storage system, the size of the container is reduced.
[0045] like Figure 2 and Figure 3 As shown, the second arrangement compartment 20 may be provided with a first sub-compartment 21 and a second sub-compartment 22 along the height direction of the enclosure 100. The first sub-compartment 21 may be located above the second sub-compartment 22. During assembly, the heat dissipation module can be placed in the upper first sub-compartment 21, and the electrical module can be placed in the lower second sub-compartment 22. It should be noted that the electrical module may include PCS equipment, a customer wiring area, a liquid cooling unit 2221, and fire-fighting devices 2222, etc.
[0046] For example, the heat dissipation module can employ at least one of a heat exchanger and a fan; that is, the heat dissipation module can use either a heat exchanger or a fan, or both, to achieve efficient and rapid heat dissipation. The heat exchanger can be a water-cooled heat exchanger, an air-cooled heat exchanger, etc.
[0047] like Figure 4 As shown, the second compartment 22 may include a first functional partition 221 and a second functional partition 222. The first functional partition 221 forms a PCS placement area 2211 for placing PCS equipment and a wiring area 2212 for customer wiring. Meanwhile, the second functional partition 222 can place a liquid cooling unit 2221 and a fire protection device 2222.
[0048] For example, such as Figure 4 and Figure 5 As shown, the first functional partition 221 and the second functional partition 222 can be distributed adjacently along the width direction of the container 100, and the PCS placement area 2211 and the wiring area 2212 can be distributed adjacently along the length direction of the container 100, so that all PCS equipment can be exposed on the operating surface of the front of the container 100, thereby facilitating the back-to-back installation of two energy storage containers, such as... Figure 9 As shown. It should be noted that the front of the container 100 is the side of the energy storage container that the operator faces, and the back of the container 100 is the side opposite to the front of the container 100.
[0049] For example, such as Figure 6 and Figure 7 As shown, the PCS placement area 2211 and the second functional area 222 can be distributed adjacently along the length of the container 100, and the PCS placement area 2211 can be located on the side away from the first arrangement compartment 10. Meanwhile, the wiring area 2212 and the second functional area 222 can be distributed adjacently along the width of the container 100 and are adjacent to the first arrangement compartment 10, so that all PCS equipment can be exposed on the operating surface of the side of the container 100, thus facilitating the back-to-back arrangement of two energy storage containers, such as... Figure 11 As shown. Of course, the PCS placement area 2211 can be adjacent to the first arrangement compartment 10, while the wiring area 2212 and the second functional area 222 can be distributed adjacently along the width direction of the container 100, and positioned away from the side of the first arrangement compartment 100, so that all PCS equipment can be exposed on the operating surface of the front of the container 100, thus facilitating the back-to-back arrangement of two energy storage containers, such as... Figure 12 As shown.
[0050] like Figure 2As shown, the wiring area 2212 and the PCS placement area 2211 are distributed adjacently along the length of the enclosure 100, and a first partition 30 is provided between the wiring area 2212 and the PCS placement area 2211 to separate the wiring area 2212 and the PCS placement area 2211. This prevents problems such as coolant leakage and arcing caused by PCS equipment failure from posing a danger to the wiring area 2212 for customer wiring. At the same time, the first partition 30 can separate the wiring area 2212 and the PCS placement area 2211 to form compartments with different protection levels to achieve different levels of protection.
[0051] This application also discloses an energy storage system, characterized in that it includes an energy storage container, which is the energy storage container disclosed in the above embodiments. Therefore, the energy storage system has all the technical effects of the above-mentioned energy storage container, which will not be repeated here.
[0052] Among them, such as Figures 9 to 12 As shown, an energy storage container may include at least two, that is, there may be two, three or more energy storage containers. When there are two energy storage containers, the two energy storage containers can be placed side by side along the length of the container body 100, as shown. Figure 10 As shown, cabinets can also be arranged along the width of the cabinet 100, such as... Figure 9 , Figure 11 and Figure 12 As shown.
[0053] For example, such as Figure 9 , Figure 11 and Figure 12 As shown, two energy storage containers can be placed side-by-side along the width of the container body 100. In this case, to ensure a small footprint for the two energy storage containers, as follows... Figure 1 As shown, the length L of the container 100 can be 9.125m to 10.255m, and the total width 2W of the two energy storage containers can be 4.876m to 5.480m. At the same time, the ratio of the length L of the container 100 to the total width 2W of the two energy storage containers can be 1.6 to 2.1.
[0054] For example, such as Figure 10 As shown, two energy storage containers can be placed side-by-side along the length of the container body 100. In this case, to ensure a small footprint for the two energy storage containers, as follows... Figure 1 As shown, the length L of the container 100 can be 18.250m to 20.510m, and the total width 2W of the two energy storage containers can be 2.438m to 2.740m. At the same time, the ratio of the length L of the container 100 to the total width 2W of the two energy storage containers can be 6.6 to 8.4.
[0055] In the above embodiments, the size of the container 100 and the arrangement of the energy storage containers can be flexibly selected according to actual needs, such as site space and energy storage effect.
