[0037] In order to improve the problem that the assembly of a battery cluster is inconvenient, time-consuming and labor-intensive, an embodiment of the present application provides a battery cluster.

[0038] Please refer to Figure 1 and Figure 2 The battery cluster 1000 provided in the embodiment of the present application includes an outer frame 100 and a battery cluster module 200. The outer frame 100 has an installation space P. The battery cluster module 200 includes a support frame 10 and a plurality of battery packs 20. Each battery pack 20 is fixedly connected to the support frame 10, and each battery pack 20 is stacked along the height direction of the battery cluster module 200. The battery cluster module 200 is configured to be movable between an assembly position outside the outer frame 100 and an installation position located in the installation space P. The battery pack 20 and the support frame 10 are configured to be assembled at the assembly position to form the battery cluster module 200, and the battery cluster module 200 can be installed on the outer frame 100 at the installation position.

[0039] The outer frame 100 is generally, but not limited to, a box-type frame structure formed by truss construction. The outer frame 100 is formed with an installation space P, and a plurality of battery cluster modules 200 can be arranged in the installation space P along the length direction of the outer frame 100 .

[0040] The battery cluster module 200 has an assembly position, which is located outside the outer frame 100. At the assembly position, the battery pack 20 and the support frame 10 can be assembled to form the battery cluster module 200. At the assembly position, the support frame 10 can be a finished frame, or its parts can be assembled at the assembly position to obtain the support frame 10, and the assembly of the support frame 10 can also be achieved simultaneously during the process of assembling the battery cluster module 200.

[0041] During the assembly process, the battery packs 20 are stacked on the support frame 10 from bottom to top, and each layer of battery packs 20 is placed, and the battery packs 20 can be fixedly connected to the support frame 10, and the fixing method can be but is not limited to fastening connection. After the battery cluster module 200 is assembled, the battery cluster module 200 is moved to the installation position, and then the battery cluster module 200 is installed on the outer frame 100 to obtain the battery cluster 1000.

[0042] It should be noted that the battery cluster module 200 and the outer frame 100 can be installed in a manner that the battery cluster module 200 is directly placed on the outer frame 100, or the battery cluster module 200 and the outer frame 100 are fixedly connected by fasteners, snaps, bindings, etc. Preferably, the battery cluster module 200 and the outer frame 100 are detachably arranged so that the battery cluster module 200 can be moved out of the installation space P, and the battery cluster module 200 can be easily inspected outside the outer frame 100.

[0043] In the battery cluster 1000, since the battery cluster module 200 is assembled outside the outer frame 100, its assembly space is not limited by the outer frame 100, and the operation is convenient. Moreover, when assembling the battery cluster module 200, since the battery packs 20 are stacked in the height direction, the battery packs 20 located in the lower layer can support the battery packs 20 located in the upper layer, and the installation of the supporting components in the related art can be omitted, saving time and labor. In addition, since the battery packs 20 are stacked, there is no space waste between the battery packs 20, which can improve the space utilization of the battery cluster module 200 in the height direction, increase the number of battery packs 20 installed, and improve the capacity of the battery cluster 1000.

[0044] In some embodiments, reference Figure 2 , Figure 3 and Figure 4 The support frame 10 forms an installation cavity Q, and the installation cavity Q includes a lifting port K located at the top thereof. Each battery pack 20 is provided with a lifting ear 21, and the lifting ear 21 is used to connect with the lifting equipment so that the battery pack 20 can enter the installation cavity Q from the lifting port K.

[0045] The support frame 10 may be a frame structure formed by trusses, and its mounting cavity Q is usually not closed. The top opening of the mounting cavity Q forms a lifting port K. When assembling the battery cluster module 200, after the lifting equipment is connected to the lifting ears 21 of the battery pack 20, the battery pack 20 is placed into the mounting cavity Q from top to bottom through the lifting port K, and each battery pack 20 is stacked. The lifting equipment can also play the role of supporting and lifting the battery pack 20 when fixing the battery pack 20 to the support frame 10.

[0046] The lifting ears 21 can be arranged on the outer peripheral side of the battery pack 20 to facilitate connection with the lifting equipment. The lifting ears 21 can be provided with lifting holes, hooks, etc., which can be flexibly set according to the lifting method of the lifting equipment.

[0047] At this time, when assembling the battery cluster module 200 , the battery pack 20 can be moved by a lifting device, which saves manpower and also speeds up the assembly of the battery cluster module 200 .

[0048] In some embodiments, reference Figure 5 , and combined with Figures 2 to 4 Each battery pack 20 includes an outer box 22 and a battery module 23 contained in the outer box 22. The top of the outer box 22 is an open end D, and the outer box 22 includes a bottom plate (not shown) disposed opposite to the open end D. In two adjacent layers of battery packs 20, the bottom plate of the upper battery pack 20 covers the open end D of the lower battery pack 20.

[0049] The outer box 22 may include a bottom plate and a frame 22c, wherein the bottom plate is disposed at one end of the frame 22c, and the other end of the frame 22c is an open end D, and the bottom plate and the frame 22c together enclose a receiving cavity for receiving the battery module 23. In each adjacent two layers of battery packs 20, the bottom plate of the upper battery pack 20 covers the open end D of the lower battery pack 20, that is, the upper and lower battery packs 20 share a bottom plate, thereby reducing the height occupied by the battery pack 20, improving the space utilization of the battery cluster module 200 in the height direction, and saving consumables.

[0050] The battery module 23 is a battery module formed by arranging a plurality of battery cells side by side. The battery module 23 includes a packaging structure, through which the battery cells are bundled together to form a whole. The packaging structure may include end plates and side plates, etc. A battery cell is the smallest unit for an electrochemical reaction, and generally includes a housing, an electrode assembly disposed in the housing, an electrolyte, etc. The electrode assembly generally includes a positive electrode sheet, a negative electrode sheet, and a diaphragm, and the diaphragm is insulated and isolated between the positive electrode sheet and the negative electrode sheet. For the specific structure of the battery module 23 and the battery cell, please refer to the conventional settings in the art.

[0051] In some embodiments, a flow channel for circulating a heat exchange medium is provided in the bottom plate, and the bottom plate is thermally connected to the battery module 23 located above and / or below.

[0052] That is, the bottom plate also serves as a liquid cooling plate. The heat of the battery module 23 can be transferred to the bottom plate, and when the heat exchange medium flows in the flow channel of the bottom plate, it takes away the heat of the bottom plate, thereby adjusting the temperature of the battery module 23.

[0053] The bottom plate can exchange heat for the battery modules 23 in the same battery pack 20, and can also exchange heat for the battery modules 23 in another battery pack 20 located therebelow, thereby improving the heat exchange efficiency of the heat exchange medium.

[0054] Specifically in the embodiment, refer to Figure 5 The battery pack 20 includes a heat conductive member 24 , and the battery module 23 and the bottom plate are thermally connected via the heat conductive member 24 .

[0055] The heat conductive member 24 can be a flexible member, for example, the heat conductive member 24 can be a silicone heat conductive pad, a gel heat conductive layer, etc., which can not only conduct heat, but also be flexibly connected between the battery module 23 and the bottom plate, so that the battery module 23 is in closer contact with the bottom plate and the heat conductive effect is better.

[0056] Understandably, a heat conductor 24 is disposed above and / or below the battery module 23, and the battery module 23 is thermally connected to the bottom plate of the battery pack 20 located above via the heat conductor 24 located above, and the battery module 23 is thermally connected to the bottom plate of the battery pack 20 located therein via the heat conductor 24 located below. Usually, a pole is disposed on the top of the battery module 23, and the heat conductor 24 is used to connect between the battery module 23 and the bottom plate, so that the heat exchange between the bottom plate and the battery module 23 can be more reliable.

[0057] In some embodiments, reference Figure 5 A seal 25 is provided between the bottom plate and the open end D covered therewith. The seal 25 is generally a sealing ring, and the shape of the seal 25 is designed to follow the contour of the open end D. The seal 25 seals the open end D of the bottom plate to prevent external water vapor from entering the battery pack 20 through the gap between the bottom plate and the open end D, which helps to reduce the risk of insulation failure of the battery module 23.

[0058] In some embodiments, the bottom plate and the open end D covered therewith are concave-convex matched in the height direction. For example, the bottom surface of the bottom plate is provided with a groove, and the end surface of the open end D is provided with a protrusion, and the protrusion is concave-convex matched with the groove. Specifically, the groove can be ring-shaped, and the sealing member 25 can be embedded in the groove and seal the groove and the protrusion.

[0059] When stacking the battery packs 20 from top to bottom, the positions of the battery packs 20 can be quickly located and the battery packs 20 can be correctly installed through the concave-convex matching between the bottom plate and the open end D.

[0060] In some embodiments, reference Figure 5 In two adjacent layers of battery packs 20, the battery pack 20 located on the upper side has a first matching piece 26, and the battery pack 20 located on the lower side has a second matching piece 27, and the first matching piece 26 and the second matching piece 27 are matched and locked.

[0061] The first fitting 26 and the second fitting 27 are arranged on the outside of the battery pack 20 to facilitate the operation of locking. It is possible that the first fitting 26 and the second fitting 27 both have locking holes, and the first fitting 26 and the second fitting 27 are locked by fastening screws, fastening bolts, etc. through the locking holes. Of course, the first fitting 26 and the second fitting 27 can also be a combination of a buckle and a snap ring, and the buckle is clamped in the snap ring to achieve the locking of the two. The specific structure of the first fitting 26 and the second fitting 27 can be conventionally set.

[0062] When assembling the battery cluster module 200, after stacking the battery packs 20, locking the first fittings 26 and the second fittings 27 on the two adjacent layers of battery packs 20 can not only make the position between the battery packs 20 firm, but also help the bottom plate to fit more closely with the open end D, thereby improving the sealing of the battery pack 20.

[0063] In some embodiments, reference Figure 3 and Figure 4 , the battery pack 20 at the top also includes a top cover 22b, and the top cover 22b covers the open end D of the battery pack 20. At this time, the top cover 22b can be used to seal and protect the top battery pack 20. It is possible to set a flow channel for circulating a heat exchange medium in the top cover 22b, and use the top cover 22b to exchange heat for the battery module 23 in the top battery pack 20. A heat conductor 24 can be set between the battery module 23 and the top cover 22b, so that the battery module 23 and the top cover 22b have good thermal conductivity. A sealing member 25 can also be set between the open end D and the top cover 22b, and the open end D and the top cover 22b can also be concave-convex.

[0064] In some embodiments, reference Figure 2 The battery pack 20 is provided with a mounting folding ear 28, and the mounting folding ear 28 is fastened to the support frame 10 via a fastener. The mounting folding ear 28 can be provided on the frame 22c of the outer box 22, and a connection hole can be provided thereon. The mounting folding ear 28 is fixedly connected to the support frame 10 by fasteners such as screws penetrating the connection hole, thereby achieving the fixation of the battery pack 20 on the support frame 10 and improving the installation reliability of the battery pack 20.

[0065] Specifically, the mounting folding ear 28 includes a first portion and a second portion that are bent, the first portion can be fastened, welded, etc., and the second portion is used to be fixedly connected to the support frame 10. Specifically, a plurality of mounting folding ears 28 are arranged on the frame 22c, and the plurality of mounting folding ears 28 are arranged at intervals along the surrounding direction of the frame 22c, so that the battery pack 20 can be installed more reliably.

[0066] In some embodiments, reference Figures 2 to 4An insertion space C is formed at the bottom of the support frame 10, and the insertion space C is used for transportation equipment to pass through so as to move the battery cluster module 200 between the assembly position and the installation position by the transportation equipment.

[0067] The transport equipment may be a forklift or other equipment with a fork arm. After the fork arm of the transport equipment is inserted into the insertion space C, the assembled battery cluster module 200 is lifted and transported to the installation space P to install the battery cluster module 200 in the outer frame 100. The battery cluster module 200 is heavy, and transporting it by the transport equipment is more labor-saving and reliable.

[0068] Of course, in other embodiments, running wheels may be provided at the bottom of the support frame 10. The staff may push the running wheels of the support frame 10 to roll, so that the battery cluster module 200 moves from the assembly position to the installation space P. A slide rail may also be provided on the outer frame 100, and the running wheels move along the slide rail to allow the battery cluster module 200 to enter the installation space P.

[0069] In some embodiments, reference Figure 2 , Figure 3 and Figure 4 The support frame 10 includes a first frame body 11 and a second frame body 12 . The first frame body 11 and the second frame body 12 are spaced apart to form an installation cavity Q for accommodating the battery pack 20 . The first frame body 11 and the second frame body 12 are connected via each battery pack 20 .

[0070] When assembling the battery cluster module 200, the first frame 11 and the second frame 12 are first placed at intervals, and then the bottom battery pack 20 is lifted by a lifting device, and the bottom battery pack 20 is fixed to the first frame 11 and the second frame 12, and then the remaining battery packs 20 are lifted in turn, and each time a layer of battery packs 20 is stacked, the mounting ears 28 of the battery pack 20 are fixedly connected to the first frame 11 and the second frame 12.

[0071] In this process, the battery pack 20 can be used to fix the first frame 11 and the second frame 12, and no other structure is needed to fix the first frame 11 and the second frame 12 together, which can simplify the structure of the support frame 10 and shorten the assembly process of the support frame 10.

[0072] The space below the lowest battery pack 20 can be used as the insertion space C.

[0073] Of course, in other embodiments, the support frame 10 may also include a cross frame (not shown), which is connected between the lower end of the first frame 11 and the lower end of the second frame 12. The space above the cross frame forms an installation cavity Q, and the space below the cross frame forms an insertion space C. The cross frame can be used to support the bottom battery pack 20. With the support of the cross frame, the battery pack 20 can be fixed to the support frame 10 without the need for lifting equipment to support the battery pack 20.

[0074] Specifically in one embodiment, refer to Figure 2 , Figure 3 and Figure 4 The first frame 11 and the second frame 12 each include a plurality of longitudinal beams 10a and a lower cross beam 10b. The plurality of longitudinal beams 10a are arranged at intervals, and adjacent longitudinal beams 10a are fixed by the lower cross beam 10b. The upper ends of the first frame 11 and the second frame 12 are open so that when the battery pack 20 is lifted, the interval space between the longitudinal beams 10a is provided for the installation folding ears 28 and the lifting ears 21 on the battery pack 20 to avoid interference.

[0075] Further, refer to Figure 2 , Figure 3 and Figure 4 The support frame 10 may further include an upper cross beam 13. After the battery pack 20 is installed, the upper cross beam 13 is fixed to the upper ends of the first frame 11 and the second frame 12 to strengthen the connection strength between the upper ends of the longitudinal beams 10a and improve the structural stability of the support frame 10.

[0076] In a specific embodiment of the present application, the support frame 10 is formed with an installation cavity Q, and the installation cavity Q has a lifting port K. The battery pack 20 is provided with a lifting ear 21, a mounting folding ear 28, a first fitting 26, and a second fitting 27. The assembly process of the battery cluster module 200 is roughly as follows: the lifting ear 21 of the battery pack 20 is connected by a lifting device, and the battery pack 20 located at the bottom of the installation space P is lifted by the lifting device, and the mounting folding ear 28 of the bottom battery pack 20 is locked with the support frame 10, and then the remaining battery packs 20 are stacked and placed on the battery pack 20 below from the lifting port K, and the top cover 22b is covered on the topmost battery pack 20 by locking the mounting folding ear 28 with the support frame 10, locking the first fitting 26 and the second fitting 27.

[0077] Finally, the battery cluster module 200 is inserted into the insertion space C and lifted by a transport device, and the battery cluster module 200 is sent into the installation space P of the outer frame 100 to obtain the battery cluster 1000 .

[0078] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
