Description

Technical Field

[0001] The present disclosure relates to the technical field of energy storage, and in particular to a battery cluster rack for placing a battery PACK and a battery container comprising the battery cluster rack and the battery PACK installed in the battery cluster rack. Background Art

[0002] With the development of the power and energy storage industries, lithium battery power and energy storage have ushered in great opportunities for development. As the core part of power and energy storage, the battery PACK is usually fixedly installed on the battery cluster rack to form a battery container. In addition to meeting the requirements of structural layout and electrical performance, the battery container must also consider mechanical safety performance. Specifically, in order to enhance the safe fixing structure of the battery PACK and the battery cluster rack, in addition to meeting the national standards GB / T36276-2023, GB / T4857.1-92 and other packaging and transportation standards, mechanical safety, stability and reliability must also be considered to achieve a certain design service life and meet customer needs.

[0003] At present, most of the battery containers on the market use bolts to connect and fix the side beams on both sides of the front end of the battery PACK to the side beams of the battery cluster frame. This solution only has two fixing points at the front end of the battery PACK and the battery cluster frame. Some battery containers have two locating pins added to the tail of the battery PACK and the battery cluster frame for reinforcement. The above solutions may be feasible for small energy storage battery PACKs (battery PACKs with small size and light weight). However, at present, with the development of technology, the energy ratio and power of battery PACKs are constantly improving, and the size and weight of battery PACKs are getting larger and larger. The current solutions mentioned above no longer meet the mechanical safety requirements, and there are even risks for the national standard test requirements for energy storage.

It will also be understood that terms such as those defined in common dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the related art and the present disclosure, and will not be interpreted as having an idealized or overly formal meaning unless the present disclosure clearly so defines.

[0028] In the following description, the terms "upper", "lower", "left", "right", "front", "rear", and other terms related to orientation are defined based on the orientation of the battery cluster rack and the battery container placed on the ground. However, it should be understood that the terms related to orientation in the present disclosure are for illustrative purposes only and are not intended to limit the direction.

[0029] In the accompanying drawings, the XYZ coordinate system is appropriately shown as a three-dimensional rectangular coordinate system. In the XYZ coordinate system, the Z-axis direction is the vertical direction. The +Z side is the upper side in the vertical direction, and the -Z side is the lower side in the vertical direction. In the following description, the upper side in the vertical direction is simply referred to as the "upper side", and the lower side in the vertical direction is simply referred to as the "lower side". The X-axis direction is a direction orthogonal to the Z-axis direction and is the left-right direction of the battery cluster rack or the battery container. The +X side is the left side of the battery cluster rack or the battery container, and the -X side is the right side of the battery cluster rack or the battery container. The Y-axis direction is a direction orthogonal to both the X-axis direction and the Z-axis direction and is the front-rear direction of the battery cluster rack or the battery container. The front-rear direction and the left-right direction are horizontal directions orthogonal to the vertical direction. In the following description, the -Y side corresponds to the front side, and the +Y side corresponds to the rear side.

[0030] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present disclosure provides a battery cluster rack 20, which is formed with a first support member 23 and a second support member 24 that are oppositely arranged for supporting the battery PACK 30. Each of the first support member 23 and the second support member 24 is provided with: at least one limiting portion 26, which is located upstream of the end of the installation path S of the battery PACK 30 in the direction in which the battery PACK 30 is pushed into the battery cluster rack 20 and is used for cooperating with at least one limiting cooperation portion 32 formed on the battery PACK 30; and an inclined surface portion 27, which is located at the end of the installation path S and is used for cooperating with an inclined surface cooperation portion 33 formed on the battery PACK 30.

[0031] During the process of installing (pushing) the battery PACK 30 into the battery cluster rack 20, first place both sides of the end of the bottom of the battery PACK 30 on the first support member 23 and the second support member 24, and then push the battery PACK 30 to insert it along the first support member 23 and the second support member into the accommodation space C of the PACK 30 (as Figure 1Inside as shown. It should be understood that there is an insertion opening in the front of the accommodation space C, and during the installation process, the battery PACK 30 is gradually pushed from the front of the accommodation space C to the rear of the accommodation space C through this insertion opening. The installation path S is the path that the battery PACK 30 slides through during the process of being pushed into the accommodation space C. The front of the accommodation space C corresponds to the front end of the installation path S, and the rear of the accommodation space C corresponds to the end of the installation path S. More specifically, as Figures 1 to 3 shown, the installation path S refers to the path of pushing the battery PACK 30 from the insertion opening on the -Y side of the accommodation space C to the rear of the accommodation space C in the front-rear direction. The upstream side of the installation path S refers to the side close to the insertion opening of the accommodation space C. The downstream side of the installation path S refers to the side opposite to the insertion opening of the accommodation space C (the side close to the end of the battery PACK 30 abutting against the battery cluster frame 20 after the battery PACK 30 is installed). In addition, the front end of the battery PACK 30 refers to the end on the -Y side (front side) of the battery PACK 30 in the front-rear direction after the PACK 30 is installed, and the end (tail) of the battery PACK 30 refers to the end on the +Y side (rear side) of the battery PACK 30 in the front-rear direction after the PACK 30 is installed.

[0032] As Figure 1 shown, the battery cluster frame 20 may include a base 21 and columns 22. The base 21 may be a frame structure formed by crossbeams parallel to the ground. The columns 22 may be provided on the base 21 and extend vertically perpendicular to the base 21. For example, the battery cluster frame 20 may include two rows of columns 22, each row including three columns 22. The first row of columns supports multiple layers of first support members 23 extending horizontally, and the second row of columns supports multiple layers of second support members 24 extending horizontally. The first support member 23 of each layer and the second support member 24 of the corresponding layer are at the same height on the columns 22 and together with the columns 22 form an accommodation space C for accommodating the battery PACK 30.

[0033] Although Figure 1 the embodiment shows that an accommodation space C for the battery PACK 30 is formed between two rows of columns 22, it should be understood that it may include three rows, four rows or more rows of columns 22, and an accommodation space C for accommodating the battery PACK 30 is formed between adjacent two rows of columns 22 by setting the first support member 23 and the second support member 24. It should also be understood that although Figure 1 the embodiment shows that the first support member 23 or the second support member 24 is supported by a row of three columns 22, the first support member 23 or the second support member 24 may be supported by setting fewer or more columns 22 in a row (for example, setting two columns in a row, or setting four columns in a row). It should also be understood that although Figure 1Only two layers of the first support member 23 and the second support member 24 supported by the column 22 are shown exemplarily herein, but fewer or more layers of the first support member 23 or the second support member 24 may be provided on the column 22 in the vertical direction, that is, there may be provided an accommodation space C for one battery PACK 30 or accommodation spaces C for more than two battery PACKs 30.

[0034] Although the frame structure for accommodating the battery PACK 30 is shown in the figure, it should be understood that the structure is not limited thereto. For example, a cabinet structure including a covering panel for accommodating the battery PACK 30 may be formed.

[0035] See Figure 1 , the first support member 23 and the second support member 24 are symmetrical structures with respect to each other and are respectively used to support both sides of the battery PACK 30. The first support member 23 and the second support member 24 may be made of 4340 / 590DP steel, for example, and the surfaces of the first support member 23 and the second support member 24 are insulated.

[0036] In some embodiments, each of the first support member 23 and the second support member 24 further includes a fastening portion 25 located at the front end of the installation path S, at least one limiting portion 26 is located between the fastening portion 25 and the inclined surface portion 27, and the fastening portion 25 forms a fastening connection with a fastening cooperation portion 31 formed on the battery PACK 30. In some embodiments, the fastening portion 25 may be a bolt hole or a threaded hole, and may be fastened to the corresponding fastening cooperation portion 31 on the battery PACK 30 through a fastener 40 such as a bolt or a screw (as Figure 3 shown in the enlarged view of the circle marked as A in the figure). By providing the fastening portion 25, a mechanical bolt hard connection can be made to the front end of the battery PACK 30 installed on the battery cluster rack 20.

[0037] The at least one limiting portion 26 may have different sizes and shapes according to the components themselves. In embodiments where there are multiple limiting portions 26, the arrangement of the multiple limiting portions 26 is not limited to a specific manner. For example, the multiple limiting portions 26 may be arranged in a straight line along the installation path S, or may be juxtaposed in a direction perpendicular to the installation path S.

[0038] The at least one limiting portion 26 is used to cooperate with at least one corresponding limiting cooperation portion 32 formed on the battery PACK 30 in a releasable manner, so as to limit the battery PACK 30, for example, in the horizontal direction perpendicular to the installation path S on the installation path S through the first support member 23 and the second support member 24.

[0039] In some embodiments, the at least one limiting portion 26 is formed as a concave portion or a convex portion.

[0040] In some embodiments, as Figure 2As shown (only the structure of the second support member 24 is shown, and for the first support member 23, its structure is similar to that of the second support member 24 and is symmetric to the structure of the second support member 24), each of at least one limiting portion 26 is formed as a recess recessed from the support surface of the first support member 23 or the second support member 24 that supports the battery PACK 30, so as to cooperate with the limiting mating portion 32 of the battery PACK 30 formed as a corresponding convex portion. In some embodiments, the recess is open on the side facing the second support member 24 or the first support member 23. For example, as Figure 1 shown, the recess (limiting portion 26) on the first support member 23 arranged on the right side in Figure 1 is open towards the left side in the figure, and the recess (limiting portion 26) on the second support member 24 arranged on the left side in Figure 1 (not visible in Figure 1 ) is open towards the right side in the figure. Thus, as Figure 5 shown, when the corresponding convex portion (limiting mating portion 32) at the bottom of the battery PACK 30 is fitted into the recess in the first support member 23 or the second support member 24, a part of the corresponding convex portion can extend out from the above-mentioned open portion of the recess (limiting portion 26). In this way, the cooperation between the convex portion 32 of the battery PACK 30 and the recess 26 on the first support member 23 or the second support member 24 can be achieved without particularly precise dimensions.

[0041] In some embodiments, although not shown in the figure, each of at least one limiting portion 26 can also be formed as a convex portion (limiting portion 26) with an arc-shaped cross-section protruding from the support surface of the first support member 23 or the second support member 24 that supports the battery PACK 30, so as to cooperate with the limiting mating portion 32 of the battery PACK 30 formed as a corresponding recess. In this way, when the battery PACK 30 is installed on the first support member 23 or the second support member 24, the corresponding recess 32 at the bottom of the battery PACK 30 can easily slide over the convex portion 26 and form a cooperation with the convex portion 26.

[0042] In some embodiments, although not shown in the figure, each of at least one limiting portion 26 can also be formed as a positioning piece provided on the support surface of the first support member 23 or the second support member 24 that supports the battery PACK 30. The positioning piece is concave-shaped in a cross-section perpendicular to the installation path S and is open along the installation path S, so as to cooperate with the limiting mating portion 32 of the battery PACK 30 formed as a corresponding convex-shaped positioning piece.

[0043] It should be understood that the structure of at least one limiting portion 26 is not limited to the above embodiments, as long as the positioning and holding function between the first support member 23 or the second support member 24 and the battery PACK 30 can be achieved.

[0044] See Figure 2and Figure 6 The inclined surface portion 27 is provided at the end of each of the first support member 23 and the second support member 24 in the installation path S, and is engaged with the inclined surface mating portion 33 at the end of the battery PACK 30. The dimensions such as the inclination and thickness of the inclined surface portion 27 can be adjusted as needed. By providing the inclined surface portion 27, the clearance positioning and assembly with the battery PACK can be achieved.

[0045] In some embodiments, as Figure 1 , Figure 2 and Figure 7 shown, the inclined surface portion 27 can protrude upward from the end of the first support member 23 or the second support member 24 at the end of the installation path S, and includes an inclined surface 271 that is inclined downward and inclined toward the upstream side of the installation path. That is, the inclined surface portion 27 can be configured to include an inclined surface 271 that is inclined toward the -Y side and the -Z side in the figure (as Figure 7 shown). This configuration can also function to press the battery PACK 30 downward, thereby facilitating the firm installation of the battery PACK 30.

[0046] However, it should be understood that the configuration of the inclined surface portion 27 is not limited thereto, and the inclined surface portion 27 can be formed into an overall inclined configuration or a configuration including a part of the inclined surface. The inclination direction of the inclined surface portion 27 is not limited thereto either. The inclined surface 271 of the inclined surface portion 27 can be inclined in a direction other than the above-mentioned inclination direction, as long as it can be engaged with the corresponding inclined surface mating portion 33 of the battery PACK 30 to achieve the functions of clearance positioning and anti-hard contact.

[0047] In some embodiments, as Figure 7 shown, a buffer pad 28 can be provided on the inclined surface 271 of the inclined surface portion 27. In some embodiments, the buffer pad 28 can be formed of any suitable material such as rigid foam, rubber, plastic, etc. By providing the buffer pad 28, the hard contact between the tail (end) of the battery PACK 30 and the battery cluster frame 20 can be further prevented.

[0048] As Figure 2 shown, in some embodiments, each of the first support member 23 and the second support member 24 can be formed into a beam having an L-shaped cross section including a horizontal surface and a vertical surface. The horizontal surface (i.e., the above-mentioned support surface) is used to support the battery PACK 30 and the vertical surface is used to limit the displacement of the battery PACK 30. By setting the first support member 23 and the second support member 24 as beams having an L-shaped cross section, when installing the battery PACK 30, the first support member 23 and the second support member 24 can function as installation guides. The fastening portion 25, the limiting portion 26, and the inclined surface portion 27 can be provided on the horizontal surface of the support member.

[0049] Another embodiment of the present disclosure also discloses a battery container 10, as Figure 3 and Figure 4 shown. The battery container 10 may include the above-mentioned battery cluster rack 20 and the battery PACK 30 installed in the battery cluster rack 20. The battery PACK 30 may be provided with: two sets of limiting and mating portions 32, each set of limiting and mating portions 32 is respectively arranged on both sides of the battery PACK 30, on the upstream side of the end of the installation path S in the direction in which the battery PACK 30 is pushed into the battery cluster rack 20, and each set of limiting and mating portions 32 includes at least one limiting and mating portion 32 so as to cooperate with at least one limiting portion 26 of the first support member 23 and at least one limiting portion 26 of the second support member 24 respectively; and two inclined surface mating portions 33, which are respectively arranged on both sides of the end of the battery PACK 30 in the installation path S so as to cooperate with the inclined surface portions 27 of the first support member 23 and the second support member 24 respectively.

[0050] As Figure 4 shown, in the case where each of the first support member 23 and the second support member 24 includes a fastening portion 25 located at the front end of the installation path S, the battery PACK 30 may further include two fastening and mating portions 31 arranged on both sides of its front end. The fastening and mating portions 31 may be bolt holes or threaded holes, and may be fixedly connected to the fastening portions 25 on the first support member 23 and the second support member 24 through fasteners 40 such as bolts or screws. In some embodiments, the fastening and mating portions 31 are arranged on the side beams 35 on both sides of the battery PACK 30 (as Figure 3 and Figure 4 shown).

[0051] However, it should be understood that the structures of the fastening portions 25 on the first support member 23 and the second support member 24 and the fastening and mating portions 31 on the battery PACK 30 are not limited thereto.

[0052] As Figure 4 shown in the enlarged view of the circle marked B in, in the case where each of at least one limiting portion 26 on the first support member 23 and the second support member 24 is formed as a recess recessed from the support surface of the first support member 23 or the second support member 24 for supporting the battery PACK30, the limiting and mating portions 32 formed on both sides of the bottom of the battery PACK 30 may be formed as convex portions corresponding to the shape of the recess 26. In the case where the recess serving as at least one limiting portion 26 is open on the side facing the second support member 24 or the first support member 23, the size of the corresponding convex portion formed on the battery PACK 30 may be larger than that of the recess 26 so as to extend out from the open opening of the recess 26. Figure 5 (Especially Figure 5The enlarged view (in the circle marked D) shows the mating situation of the limiting part 26 as the concave part and the limiting mating part 32 as the convex part as described above.

[0053] In some embodiments, when each of at least one limiting part 26 is also formed as a convex part with an arc-shaped cross-section protruding from the supporting surface of the first support member 23 or the second support member 24 for supporting the battery PACK 30, the limiting mating parts 32 formed on both sides of the bottom of the battery PACK 30 can be formed as concave parts with an arc-shaped inner surface.

[0054] In some embodiments, when each of at least one limiting part 26 is formed as a positioning piece provided on the supporting surface of the first support member 23 or the second support member 24 for supporting the battery PACK 30, and the positioning piece is concave-shaped in the cross-section perpendicular to the installation path S and is open along the installation path S, the limiting mating parts 32 formed on both sides of the bottom of the battery PACK 30 can be formed as convex positioning pieces that can be engaged inside the concave shape of the positioning piece.

[0055] However, it should be understood that the structure of the limiting mating part 32 is not limited thereto.

[0056] As Figure 4 shown in the enlarged view of the circle marked C, the inclined surface mating part 33 of the battery PACK 30 can be formed as a sheet metal block extending from the end of the battery PACK 30. Figure 6 (Especially the enlarged view marked E) shows the mating situation of the inclined surface part 27 and the inclined surface mating part 33 as described above. However, it should be understood that the structure of the inclined surface mating part 33 of the battery PACK 30 is not limited thereto.

[0057] Generally, the installation depth of the battery PACK 30 in the battery cluster rack 20 is relatively deep (for example, 2.4 meters). Therefore, it is relatively difficult to mechanically fix the support members for supporting the battery PACK to the battery PACK at its middle and end. The present disclosure can achieve limiting fixation with a small size, simple structure and low cost by providing the structure of the limiting part and the inclined surface part on the support member, reducing space waste, and having high installation integration efficiency. In addition, through the combination of the two limiting structures of the limiting part and the inclined surface part, the installation of the battery PACK can be realized more firmly and reliably.

[0058] It should be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present disclosure, but the present disclosure is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the gist and essence of the present disclosure, and these modifications and improvements are also regarded as the protection scope of the present disclosure.
