Description

Technical Field

[0001] This application relates to the field of container technology, specifically to an energy storage container, and further to an energy storage system comprising the energy storage container. Background Technology

[0002] In recent years, with the rapid development of the energy storage industry, new energy storage has been gradually used in power plant regulation, industrial park peak shaving and valley filling, and microgrids. Outdoor large-scale energy storage typically integrates hundreds or thousands of energy storage batteries in series and parallel within a container, making it suitable for various scenarios. Since the energy storage batteries inside the container generate a large amount of heat during charging and discharging, and the temperature of the energy storage batteries has a significant impact on battery life and system safety, temperature control of the energy storage batteries is particularly important.

[0003] As the internal capacity of a single container increases, the heat generated by the internal components also increases, making heat dissipation inside the container an urgent problem to be solved. Existing energy storage containers generally use full liquid cooling to handle the heat generated by battery modules and electrical components. However, it is difficult to effectively dissipate heat from bottom control devices such as high-voltage control boxes or AC / DC converters at the bottom of the container. Long-term exposure to high temperatures can easily lead to a reduction in their service life, thus failing to meet the overall heat dissipation requirements of energy storage containers. Utility Model Content

Then, the airflow will transport the heat of the control box to the outside of the container through the branch air duct, thereby effectively improving the air circulation efficiency at the bottom of the container.

[0027] Two water-retaining eaves are configured to be fixedly installed in the battery area, and the two water-retaining eaves are symmetrically distributed and form a certain angle with respect to the vertical direction.

[0028] In addition to one or more of the above, or as an alternative, in other embodiments, it also includes:

[0029] The bracket, fixedly installed inside the battery area and extending vertically, is configured to have multiple brackets evenly spaced along a first direction; and / or,

[0032] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up battery and electrical zones distributed from top to bottom inside the container, battery modules and electrical devices can be installed vertically inside the container. Utilizing the main air duct located inside the electrical zone and connected to the outside, combined with the control box connected to the main air duct, air guides located inside the control box can guide external airflow into the control box through the main air duct. Then, the airflow transports the heat of the control box to the outside of the container through branch air ducts, thereby effectively improving the air circulation efficiency at the bottom of the container. This directly dissipates heat from the control box and other heat-generating devices at the bottom of the container, extending their service life while also improving the stability and safety of the container. The simple structure effectively dissipates heat from the control devices at the bottom of the container, meeting the overall heat dissipation requirements of the energy storage container.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0045] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0046] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0047] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0048] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0049] Based on existing technologies, as the internal capacity of a single container increases, the heat generated by internal components such as high-voltage control boxes or AC-DC or DC-DC converters also increases. How to meet the heat dissipation requirements of internal components while simultaneously satisfying their installation needs has become an urgent problem to be solved in the industry. Existing technologies generally solve the heat generation problem of battery modules through full liquid cooling, which is complex in structure and also makes it difficult to effectively dissipate heat from the bottom control components, thus failing to meet the overall heat dissipation requirements of energy storage containers. Therefore, this application proposes an energy storage container aimed at solving one of the above problems.

[0050] Figure 1 This is a perspective view of an energy storage container according to one embodiment of the present application. The energy storage container can be used in the field of energy storage and includes: a container 1 with an internal accommodating space, a battery area 2 and an electrical area 3 disposed inside the container 1 and distributed from top to bottom, and further includes: a main air duct 4 installed inside the electrical area 3, multiple control boxes 5 configured to communicate with the main air duct 4 and arranged sequentially along its extension direction, and branch air ducts 7 formed at the bottom of the container 1 and communicating with the outside. The main air duct 4 is configured to extend along a first direction and communicate with the outside; the branch air ducts 7 are configured to communicate with the control boxes 5 to dissipate heat from the container 1, and at least one air guide (not shown in the figure) is installed inside the control boxes 5.

[0051] It can be known that, for reference Figures 1-5 By setting up a battery area 2 and an electrical area 3 distributed from top to bottom inside the container 1, battery modules and electrical devices can be installed vertically inside the container 1. Using the main air duct 4 located inside the electrical area 3 and connected to the outside, combined with the control box 5 connected to the main air duct 4, the air guides inside the control box 5 can guide the outside airflow into the control box 5 through the main air duct 4. Then, the airflow will transport the heat of the control box 5 to the outside of the container 1 through the branch air ducts 7, thereby effectively improving the air circulation efficiency at the bottom of the container 1. This directly dissipates heat from the control box 5 and other heat-generating devices at the bottom of the container 1, extending their service life and improving the stability and safety of the container. The structure is simple and can effectively dissipate heat from the control devices at the bottom of the container, meeting the overall heat dissipation requirements of the energy storage container.

[0052] It should be noted that by placing the high-heat-generating control box 5 at the bottom of the container, the high-heat-generating product is located in the position with the lowest ambient temperature inside the container, since heat rises upwards. Furthermore, since the branch air duct 7 is located at the bottom of the container, when the energy storage container experiences thermal runaway, the flames remain at the bottom and are unlikely to emerge from the side of the box 1, further improving the reliability of the container.

[0053] In actual operation, this embodiment should be referred to Figure 2Battery area 2 and electrical area 3 can be connected. In this case, the main air duct 4 and branch air duct 7 located at the bottom can also provide some heat dissipation for battery area 2. Of course, the two can also be disconnected. Alternatively, the distribution of battery area 2 and electrical area 3 can be adjusted as needed, with electrical area 3 placed on top and battery area 2 placed on the bottom. The specific structural form can be adjusted as needed, and this embodiment does not make specific limitations here.

[0054] Specifically, by setting a ventilation port at one end of the container 1 and connecting it to the bottom main air duct 4, and arranging the control box 5 and branch air ducts 7, an effective heat dissipation path is formed, which significantly improves the heat dissipation conditions of the heat-generating components inside the energy storage container, especially the bottom control box 5, thereby enhancing the reliability and safety of the entire system.

[0055] For example, in actual operation, the control box 5 is provided with at least one air guide that communicates with the main air duct 4 on the side near the main air duct 4.

[0056] In actual operation, the configuration of the air guide inside the control box 5 significantly enhances the active heat dissipation capability of heat-generating components such as the control box 5, and improves the active regulation performance of the heat dissipation system; it actively enhances the airflow exchange from the main air duct 4 to the control box 5, thereby increasing the heat dissipation rate and making it suitable for high heat load conditions.

[0057] The following will illustrate further specific implementations or refinements and improvements to the energy storage container through exemplary description, in order to further improve it or for other improvement considerations.

[0058] Further reference Figure 6 The main air duct 4 includes a plurality of exhaust components 41 configured to be hollow inside and connected end to end in a first direction. At least one of the two ends of each exhaust component 41 in a second direction forms a vent 411. The control box 5 is connected to the side of the vent 411.

[0059] It is easy to see that by arranging the exhaust components 41 along the first direction, and setting a vent 411 on each exhaust component 41 to connect with the control box 5, it is easy to form an orderly airflow channel, which further optimizes the airflow distribution, so that the airflow along the first direction can pass through different parts of the box 1 in sequence, further enhancing the guidance of the airflow in the main air duct 4, and making the cooling effect of the control box 5 at different positions inside the box 1 more uniform and efficient.

[0060] It should be noted that by designing an exhaust component 41 with at least one vent 411, the exhaust component 41 can exhaust the hot air from the control box 5 in different directions, further improving the exhaust heat dissipation efficiency of the main air duct 4 and reducing the risk of local overheating.

[0061] In actual operation, the first direction can be the length direction of the box 1 and the second direction can be the width direction of the box 1. Of course, it can also be the opposite, with the first direction being the width direction of the box 1 and the second direction being the length direction of the box 1. This embodiment does not limit this.

[0062] Furthermore, refer to Figure 6 Each of the exhaust components 41 has two vents 411 symmetrically opened at both ends along the second direction, and the control box 5 is connected to each of the vents 411 in a corresponding manner.

[0063] It can be seen that the exhaust component 41 has symmetrical ventilation openings 411 at both ends, and the symmetrical distribution of the control box 5 ensures the balanced airflow of the main air duct 4 while realizing the normal control and operation of the battery module inside the battery area 2.

[0064] For example, the exhaust component 41 is configured as a hollow shell structure with openings at both ends, which facilitates communication with other exhaust components 41. As for the shape of its cross-section, it can be rectangular or trapezoidal, or circular or other shapes, as long as it can achieve uniform airflow. This embodiment does not make specific limitations here.

[0065] In one embodiment, each of the exhaust components 41 has two vents 411 symmetrically opened at both ends along the second direction, and the control box 5 is connected to each of the vents 411 in a corresponding manner.

[0066] It is not difficult to see that, reference Figure 6 By setting the ventilation opening 411 into a symmetrical structure, not only can the heat dissipation of the control box 5 be effectively achieved, but it is also easy to achieve uniform airflow and avoid noise that may be caused by uneven flow at different locations.

[0067] For example, regarding the number of ventilation openings 411 on the exhaust component 41, in addition to setting one, it can also be set to two, or of course, multiple, to correspond to different branch air ducts 7. The specific number and distribution method can be selected as needed, and this embodiment does not make specific limitations here.

[0068] In one embodiment, reference is made to... Figure 5 and Figure 6 It also includes: a beveled portion 412 formed at the bottom of at least one of the two ends of the exhaust member 41 along the second direction, and the beveled portion 412 is configured to form a certain angle with the central axis.

[0069] It is easy to see that the inclined chamfer design at the bottom of the exhaust component 41 not only effectively reduces airflow resistance, but also reduces the generation of eddies, improves the smoothness of airflow in the duct, and reduces noise.

[0070] For example, the aforementioned included angle can be set to an acute angle, and other angles can be selected as needed. This embodiment does not make specific limitations here. There are two oblique angle portions 412 that are symmetrically distributed with respect to their central axis, and each oblique angle portion 412 is configured to form a certain angle with its central axis.

[0071] In another embodiment, reference is made to... Figure 5 and Figure 7 The bottom of the control box 5 is also provided with an exhaust port 51 that communicates with the branch air duct 7. Several air guide ports 52 are provided on the side of the control box 5 near the main air duct 4, and the air guide 6 is provided inside the air guide ports 52.

[0072] It is easy to see that the side of the control box 5 is connected to the main air duct 4 through the air guide 52, and the exhaust vent 51 at the bottom of the control box 5 is connected to the branch air duct 7, which ensures that hot air can be quickly discharged outside the box, reducing heat accumulation and enhancing the heat dissipation effect. Since the branch air duct 7 is set through the bottom of the box 1 and is connected to the outside, even if thermal runaway occurs, the flame is still difficult to come out from the side of the box 1, further improving the safety and reliability of the energy storage container.

[0073] Further reference Figure 5 The branch air duct 7 extends vertically and is configured such that one end opposite to the exhaust port 51 passes through the bottom surface of the box 1 and is connected to the outside.

[0074] For example, the extension direction of the branch air duct 7 can also be selected and adjusted as needed. The vertical direction in this embodiment is only a preferred option. In actual operation, the branch air duct 7 can also be opened at an angle at the bottom of the box 1, or it can be set into other cross-sectional shapes.

[0075] For example, the above-mentioned air guide can be set as a fan or blower and placed inside the control box 5 to realize the air flow of the main air duct 4, the control box 5 and the branch air duct 7, and accelerate the heat dissipation of the bottom control box 5. The specific type and shape can be adjusted as needed, and this embodiment does not make specific limitations here.

[0076] In actual operation, this embodiment should be referred to Figure 5 and Figure 7 The control box 5 is configured as a high-voltage control box, or an AC-DC controller, or a DC-DC controller.

[0077] It can be seen that the control box 5 is mainly for the actual heat-generating devices inside the electrical area 3. It can be a high-voltage control box, an AC-DC controller, or a DC-DC controller. By heat dissipating these heat-generating devices, the heat dissipation requirements of the devices at the bottom can be effectively improved, and the heat dissipation needs can be met.

[0078] For example, the control box 5 mentioned above can be any other controller or heating device besides a high-voltage control box, as long as it can dissipate heat from the bottom device. The specific type can be adjusted according to the actual situation, and this embodiment does not make any specific limitations here.

[0079] In actual operation, this embodiment should be referred to Figure 2 and Figure 4 It also includes: a ventilation unit 8 installed on at least one side of the housing 1 and connected to the outside, wherein one end of the main air duct 4 along the first direction is connected to the ventilation unit 8.

[0080] It is easy to see that by setting up ventilation unit 8, the main air duct 4 and the outside air can be connected to achieve the overall flow of air between ventilation unit 8, main air duct 4, control box 5 and branch air duct 7.

[0081] In one embodiment, reference is made to... Figure 2 and Figure 4 The ventilation unit 8 includes: a ventilation frame 81 configured to be fitted into one end opening of the housing 1 along a first direction and connected to the external airflow; and an air inlet 82 formed on the side of the ventilation frame 81 near the opening and configured to be connected to the main air duct 4.

[0082] It can be understood that the ventilation unit 8 is configured as a ventilation frame 81 to facilitate the guidance of external airflow, while the air inlet 82 can introduce the guided air into the main air duct 4 to achieve the guidance of external airflow. In addition, the design of the ventilation frame 81 and the air inlet 82 provides a path for the smooth entry of external air and enhances the air intake efficiency of the main air duct 4.

[0083] Further reference Figure 2 and Figure 4 It also includes: a louver 9 installed on the side of the ventilation frame 81 away from the air inlet 82, the louver 9 being configured to extend from the bottom end to the top end of the ventilation frame 81, with a gap between two adjacent louvers for airflow to pass through.

[0084] It is easy to see that the installation of the louver 9 is not only aesthetically pleasing, but also effectively regulates the airflow, preventing foreign objects from entering while ensuring air circulation, thus enhancing the practicality of the energy storage container.

[0085] In one embodiment, a water-blocking member 10 is also installed at the bottom of the battery area 2, and the water-blocking member 10 is configured such that the middle position is higher than the edge position.

[0086] It can be known that, for reference Figure 2 and Figure 4 The introduction of the water-blocking component 10, especially its design with a high center and low edges, effectively prevents condensate from accumulating near the control box 5, protects the bottom control box 5 from the influence of condensate, and further improves the reliability and safety of the system.

[0087] Specifically, the design of the water-blocking component 10 effectively solves the problem of condensation accumulation. By guiding water flow to a safe area that does not affect electrical components, it improves the waterproof performance and long-term operational stability of electrical components.

[0088] In practical applications, this embodiment should be referenced. Figure 2 and Figure 4 The water-blocking component 10 includes two water-blocking eaves fixedly installed between two adjacent battery brackets 6 in the battery area 2. The two water-blocking eaves are symmetrically distributed and form a certain angle with respect to the vertical direction.

[0089] It can be seen that by installing a water-retaining eave above the control box 5 inside the container, when the battery pack above leaks or condensation occurs inside the box 1, the water flows to both sides along the water-retaining eave, thus preventing any impact on the air-cooling equipment and electrical components at the bottom.

[0090] It should be noted that by setting the above-mentioned water-blocking component 10 as a water-blocking eave, not only is the flow of condensate water effectively guided, but also the installation at a specific angle is conducive to drainage and prevents water droplets from falling directly into the control box 5, thus optimizing drainage efficiency, preventing safety hazards caused by water accumulation, and protecting the electrical equipment at the bottom.

[0091] For example, the two water-blocking eaves mentioned above can be symmetrically distributed on both sides of the main air duct 4 along the second direction, thereby covering the two control boxes 5 on both sides of the main air duct 4. Of course, the water-blocking component 10 mentioned above can also be a conical structure or other irregular shape. This embodiment does not make specific limitations here.

[0092] Further reference Figure 2 and Figure 4 It also includes: a bracket 6 fixedly installed inside the battery area 2 and extending in a vertical direction, the bracket 6 being configured to have multiple brackets at equal intervals along a first direction; and / or, a battery box (not shown in the figure) overlapping between two adjacent brackets 6 and configured to be stacked at equal intervals along a vertical direction; the water-blocking member 10 is fixedly installed between two adjacent brackets 6 and located below the bottommost battery box.

[0093] It can be seen that by setting the bracket 6 extending in the vertical direction, the installation of the battery box can be provided by two adjacent brackets 6, and the installation of the water-blocking component 10 can also be provided. This not only optimizes the internal space of the box 1, but also achieves effective heat dissipation of the bottom control box 5 and the upper battery box. The structure is simple and has strong practicality.

[0094] Furthermore, refer to Figure 2 The exhaust component 41 of the main air duct 4 is installed in the cavity between two adjacent brackets 6 and is configured to correspond one-to-one with the cavity.

[0095] It is easy to see that the one-to-one correspondence between the exhaust component 41 and the cavities formed by the two adjacent brackets 6 makes the airflow distribution more reasonable, and the control box 5 at the bottom of each cavity that generates heat can be effectively cooled, further improving the overall heat dissipation effect.

[0096] In one embodiment, an energy storage system is also provided, including: the energy storage container as described above.

[0097] In this arrangement, the energy storage system described in this paper, constructed using an energy storage container with this design, utilizes a main air duct 4 located inside the electrical zone 3 and connected to the outside. Combined with a control box 5 connected to the main air duct 4, external airflow is guided into the control box 5 through the main air duct 4 via air guides located inside the control box 5. Then, the airflow transports the heat from the control box 5 to the outside of the container 1 through branch air ducts 7, thereby effectively improving the air circulation efficiency at the bottom of the container 1. This directly dissipates heat from heat-generating components such as the control box 5 at the bottom of the container 1, extending their service life while also improving the stability and safety of the container. The structure is simple, and it can effectively dissipate heat from the control components at the bottom of the container, meeting the heat dissipation requirements of the energy storage system.

[0098] The above examples primarily illustrate the energy storage container and the energy storage system including the energy storage container of this application. Although only some embodiments of this application have been described, those skilled in the art should understand that this application can be implemented in many other forms without departing from its spirit and scope. Therefore, the examples and embodiments shown are considered illustrative rather than restrictive, and this application may cover various modifications and substitutions without departing from the spirit and scope of the technical solution of this application.
