[0002] With the widespread application of batteries in the field of energy storage, large-capacity battery cells have become the mainstream object of research and application for major energy storage manufacturers and users. The control of battery cell temperature, the improvement of system capacity density and the saving of system integration costs are crucial to the overall solution of container batteries, which is related to the long-term reliability and economic benefits of container batteries.

If the battery cell temperature is too low, the discharge rate of the battery cell decreases, and the battery performance is greatly reduced. Therefore, how to solve the above battery cell heat exchange problem is a difficulty faced by industry technicians. Utility Model Content

[0052] With the widespread application of batteries in the field of energy storage, large-capacity container batteries have become the mainstream object of research and application for major energy storage manufacturers and users. The control of cell temperature, the improvement of system capacity density and the saving of system integration costs in large-capacity container batteries are crucial to the overall solution of container batteries, which is related to the long-term reliability and economic benefits of container batteries.

[0053] At present, during the operation of container batteries, the battery cells need to be maintained within a suitable temperature range to ensure normal operation. If the battery cell temperature is too high, the heat generated by the battery cell cannot be removed in time, which makes the container battery prone to thermal runaway. If the battery cell temperature is too low, the discharge rate of the battery cell decreases, and the working performance of the container battery is greatly reduced. Therefore, how to solve the above battery cell heat exchange problem is a difficulty faced by industry technicians.

[0054] See also Figure 1 , Figure 2 and Figure 4 In order to alleviate the above-mentioned problem, the present application provides a cluster rack 10 for container batteries 10000, the cluster rack 10 includes a rack body 11 and a plurality of heat exchange plates 12, the rack body 11 is provided with a cavity extending along its height direction Z, the plurality of heat exchange plates 12 are arranged in the cavity, and are arranged at intervals along the height direction Z of the rack body 11, each two adjacent heat exchange plates 12 jointly define a cavity 13 for placing a battery module 200, and the heat exchange plate 12 is fitted with the battery module 200 located in the cavity 13 defined by it; wherein, the heat exchange plate 12 has a heat exchange flow channel for the flow of heat exchange fluid.

[0055] The container battery 10000 includes a battery module 200 , which may be a battery pack, a battery module, or a battery row formed by arranging a plurality of battery cells 210 .

[0056] Specifically, the battery module 200 is clamped in the cavity 13, and the top surface of the battery module 200 set along the height direction Z of the frame body 11 is in contact with the heat exchange plate 12 located on the top side and adjacent to the battery module 200, and the bottom surface of the battery module 200 set along the height direction Z of the frame body 11 is in contact with the heat exchange plate 12 located on the bottom side and adjacent to the battery module 200, so that the battery module 200 can exchange heat with the heat exchange fluid in the heat exchange plate 12 in contact with it, thereby achieving cooling or heating of the battery module 200.

[0057] As an example, the heat exchange fluid may be water, alcohol or other fluids, which may be set according to requirements.

[0058] According to the operating conditions of the container battery 10000 and the ambient temperature, a low-temperature, normal-temperature or relatively high-temperature heat exchange fluid may be introduced into the heat exchange fluid of each heat exchange plate 12 .

[0059] Taking the use of the container battery 10000 in a low temperature environment as an example, such as the use in a low temperature environment in winter, the discharge rate of the battery cell 210 in the battery module 200 decreases in the low temperature environment, and the battery performance is greatly reduced. In view of this situation, a relatively high temperature heat exchange fluid formed by heating can be introduced into the heat exchange flow channel of the heat exchange plate 12, so that the battery cell 210 can absorb the heat of the heat exchange fluid and the temperature rises, so that it can be charged and discharged normally. Taking the use of the container battery 10000 in a high temperature environment as an example, such as the use in a high temperature environment in summer, the battery cell 210 in the battery module 200 is used in a high temperature environment, and the heat generated may not be taken away in time, and thermal runaway may occur easily. In view of this situation, a low temperature heat exchange fluid formed by refrigeration can be introduced into the heat exchange flow channel of the heat exchange plate 12, so that the heat exchange fluid can absorb the temperature of the battery cell 210 and the temperature is reduced, so as to reduce the risk of thermal runaway.

[0060] As can be seen from the above, in the present application, two adjacent heat exchange plates 12 are provided to jointly define a cavity 13 for placing the battery module 200, and the heat exchange plate 12 is fitted with the battery module 200 located in the cavity 13 defined by it. In this way, the contact area between the heat exchange plate 12 and the battery module 200 can be increased, and the heat exchange capacity and heat exchange effect can be improved, so as to extend the service life of the container battery 10000.

[0061] Please refer again Figure 1 In some optional embodiments, the rack body 11 includes two rack units 111 spaced apart along its length direction X, each rack unit 111 has a plurality of slots 1111 spaced apart along the height direction Z of the rack body 11, the heat exchange plate 12 corresponds to the slots 1111 in each rack unit 111 one by one, and the opposite ends of the heat exchange plate 12 are respectively inserted into the two slots 1111 on the two rack units 111 corresponding to the heat exchange plate 12. By designing the slots 1111 to hold the heat exchange plate 12, the heat exchange plate 12 is easy and convenient to install.

[0062] Specifically, two slots 1111 corresponding to the same heat exchange plate 12 are arranged opposite to each other along the length direction X of the frame body 11 , and opposite ends of the heat exchange plate 12 are respectively inserted into the two slots 1111 corresponding to and opposite to each other.

[0063] In some optional embodiments, each frame unit 111 includes multiple vertical rods 1112 and multiple horizontal rods 1113; in the same frame unit 111, all vertical rods 1112 are arranged in sequence along the width direction Y of the frame body 11, and all horizontal rods 1113 are arranged at intervals along the height direction Z of the frame body 11, and each horizontal rod 1113 is connected to all vertical rods 1112 in the same frame unit 111; the horizontal rods 1113 in each frame unit 111 correspond one-to-one to the heat exchange plates 12, and the two surfaces of the two horizontal rods 1113 corresponding to the same heat exchange plate 12 in the two frame units 111 are recessed to form a card groove 1111.

[0064] All the vertical bars 1112 in the same rack unit 111 may be spaced or closely arranged along the width direction Y of the rack body 11 , and all the horizontal bars 1113 in the same rack unit 111 extend along the width direction Y of the rack body 11 .

[0065] Specifically, the slot 1111 extends along the width direction Y of the frame body 11 to both end surfaces of the cross bar 1113 where the slot 1111 is located.

[0066] During actual installation, the heat exchange plate 12 is inserted into the slot 1111 corresponding to the heat exchange plate 12 from any side of the frame body 11 along the width direction Y thereof, so as to assemble the heat exchange plate 12 .

[0067] By designing a method of combining multiple vertical rods 1112 and multiple horizontal rods 1113 to form the rack unit 111, the structure of the rack unit 111 is simplified, and the heat exchange plate 12 can be selectively installed from any side of the rack body 11 along its width direction Y, and the heat exchange plate 12 is simple and convenient to install.

[0068] Combination Figure 1 and Figure 2 In some optional embodiments, in the same frame unit 111, each two adjacent cross bars 1113 jointly define a smoke exhaust channel 1114, and the smoke exhaust channel 1114 defined by the two adjacent cross bars 1113 in the same frame unit 111 is connected to the cavity 13 defined by the two heat exchange plates 12 installed on the two adjacent cross bars 1113.

[0069] When the battery module 200 is working and thermal runaway occurs, the smoke exhausted from the battery cells 210 in the battery module 200 is discharged through the smoke exhaust channel 1114 connected to the cavity 13 where the battery module 200 is located, so as to avoid the smoke gathering in the cluster frame 10 and causing the battery module 200 to overheat and affect the operation, which is beneficial to improving the safety of the container battery 10000.

[0070] In some optional embodiments, a smoke exhaust channel 1114 is provided in the frame body 11 ; each cavity 13 is provided with a smoke exhaust channel 1114 on at least one side along the length direction X of the frame body 11 , and each cavity 13 is connected to the smoke exhaust channel 1114 on each side thereof.

[0071] As an example, the rack unit 111 may also include a U-shaped tube, and a U-shaped tube is also arranged between each adjacent two cross bars 1113 on the same rack unit 111. The U-shaped tube extends along the width direction Y of the rack body 11, and the U-shaped tube defines a smoke exhaust channel 1114. The smoke exhaust channel 1114 of the U-shaped tube is connected to the cavity 13 through the opening of the U-shaped tube.

[0072] The design of the smoke exhaust channel 1114 can timely exhaust the smoke released by the thermal runaway battery cell 210 in the cavity 13, thereby improving the safety of the container battery 10000.

[0073] Please refer again Figure 1 and Figure 2 In some optional embodiments, the cluster frame 10 includes a receiving cavity 14 , which is located at the bottom of all the cavities 13 and is used to receive the high-voltage box 300 .

[0074] For example, the rack body 11 may further include a bottom plate, which is located at the bottom side of the rack unit 111 and defines a receiving chamber 14 with the two rack units 111 and the heat exchange plate 12 located at the bottom in the height direction Z of the rack body 11. Alternatively, the rack body 11 may further include a first plate and a second plate, which are located at the bottom side of the rack unit 111 and are spaced apart along the height direction Z of the rack body 11, and the first plate, the second plate and the two rack units 111 define a receiving chamber 14.

[0075] The high voltage box 300 is used to control the input and output of electric energy of all battery modules 200 placed in the cluster rack 10 .

[0076] See also Figure 1 , Figure 2 and Figure 3 The present application also provides a cluster assembly 100, which includes a shell 20 and the cluster frame 10 described in any one of the above embodiments. The shell 20 is covered outside the cluster frame 10 and is used to block external moisture and dust to reduce the risk of external moisture and dust contacting the battery module 200 and affecting the operation of the battery module 200, thereby extending the life of the battery module 200.

[0077] As an example, the housing 20 may be a hollow structure with one end open and the other end closed or both ends closed, or the housing 20 may be a hollow structure with both ends closed and the sidewalls provided with heat dissipation holes. Of course, the form of the housing 20 is not limited to the above three types, and the housing 20 may also be other structures, which may be specifically set according to needs.

[0078] It is worth mentioning that the cluster assembly 100 in the present application has the effects brought by any of the above embodiments, so it will not be described in detail here.

[0079] Please refer again Figure 1 , Figure 2 and Figure 3 The present application also provides a battery cluster 1000, which includes the cluster assembly 100 described in the above embodiment and a plurality of battery modules 200, all battery modules 200 in the cluster assembly 100 correspond one-to-one to at least part of the cavity 13, the battery module 200 includes a plurality of battery cells 210, and all battery cells 210 of the same battery module 200 are stacked along the width direction Y of the frame body 11 and clamped in the cavity 13 corresponding to the battery module 200.

[0080] It can be understood that if all battery modules 200 in the cluster assembly 100 correspond one-to-one to some cavities 13, it means that only some cavities 13 in the cluster frame 10 are provided with battery modules 200; if all battery modules 200 in the cluster assembly 100 correspond one-to-one to all cavities 13, it means that battery modules 200 are provided in each cavity 13 in the cluster frame 10.

[0081] The battery modules 200 are disposed in corresponding cavities 13 , and all the battery modules 200 and the cluster assembly 100 form a battery cluster 1000 with high energy density.

[0082] Specifically, the battery module 200 can be a battery pack, a battery module, a battery row, etc., which can be set according to specific needs.

[0083] For example, taking a battery module 200 formed by arranging multiple battery cells 210 as an example, this type of battery module 200 does not need to be protected by single-pack IP (measures for preventing foreign objects from intruding and waterproofing a single battery pack), so that the single-pack IP protection can be cancelled, and the battery cluster 1000 or the container battery 10000 can be directly protected by IP, which reduces the protection cost and improves the space utilization. In addition, in this embodiment, the battery cells 210 located in the cavity 13 are relatively arranged on both sides along the height direction Z of the frame body 11. Both sides can contact the heat exchange plate 12, and the heat exchange effect is good, which ensures the consistency of the temperature of each battery cell 210 in the cavity 13. The aging speed of each battery cell 210 is basically the same, which solves the problem of maintenance required later due to the aging of local battery cells 210.

[0084] In some optional embodiments, the battery cell 210 has an explosion-proof valve and a pole, and the explosion-proof valve and the pole face the smoke exhaust channel 1114 that is connected to the cavity 13 where the battery cell 210 is located.

[0085] Specifically, the battery cell 210 has two poles, one of which is a positive pole and the other is a negative pole. The positive pole, the negative pole and the explosion-proof valve of the battery cell 210 may be located at the same end of the battery cell 210. In this embodiment, the positive pole, the negative pole and the explosion-proof valve of the battery cell 210 face the same exhaust passage 1114 connected to the cavity 13 where the battery cell 210 is located. Alternatively, the positive pole and the negative pole of the battery cell 210 may be located at opposite ends of the battery cell 210, and the explosion-proof valve and the positive pole or the negative pole are arranged at the same end. For example, the explosion-proof valve and the positive pole are located at the same end of the battery cell 210, and the explosion-proof valve and the positive pole face one exhaust passage 1114 connected to the cavity 13 where the battery cell 210 is located, and the negative pole faces another exhaust passage 1114 connected to the cavity 13 where the battery cell 210 is located.

[0086] When the pole is facing the exhaust channel 1114, the pole is in contact with the smoke or air in the exhaust channel 1114, and the insulation effect of the smoke and air is good, which can achieve insulation between the pole and the heat exchange plate 12 and the frame body 11, improve safety, and save the use of insulating materials. When the explosion-proof valve is facing the exhaust channel 1114, the smoke exhausted by the explosion-proof valve can be directly discharged through the exhaust channel 1114, and the exhaust efficiency is high.

[0087] In some optional embodiments, the battery cluster 1000 further includes a high voltage box 300 , which is disposed in the receiving cavity 14 of the cluster frame 10 .

[0088] See also Figures 1 to 5 The present application also provides a container battery 10000, which includes a container 2000 and a battery cluster 1000 as described in any one of the above embodiments. A container space 2200 is provided in the container 2000. There are multiple battery clusters 1000 arranged in the container space 2200 along the length direction and / or width direction of the container 2000 to achieve integration of the battery clusters 1000 and meet the needs of high energy density energy storage scenarios.

[0089] As an example, there may be a plurality of battery clusters 1000 , which are arranged in a matrix manner in the container space 2200 along the length direction and the width direction of the container 2000 .

[0090] In some optional embodiments, the battery clusters 1000 are arranged along the length direction of the container 2000 to form battery cluster rows, and a smoke exhaust grille 2100 is arranged between each two adjacent rows of battery cluster rows. The interior of the smoke exhaust grille 2100 is hollow to form a smoke collection channel 2110, and each side of the smoke exhaust grille 2100 is provided with a plurality of smoke exhaust ports 2120. The smoke exhaust ports 2120 on each side of the smoke exhaust grille 2100 correspond one-to-one to the smoke exhaust channels 1114 in the battery cluster row facing that side, and the smoke exhaust ports 2120 are connected between the corresponding smoke exhaust channels 1114 and the smoke collection channels 2110.

[0091] Specifically, the smoke exhaust grille 2100 includes a plurality of vertical bars 2140 and a plurality of horizontal bars 2130. The vertical bars 2140 extend in the height direction of the container 2000. All the vertical bars 2140 in the same smoke exhaust grille 2100 are arranged in the length direction of the container 2000, and a plurality of horizontal bars 2130 connecting the two vertical bars 2140 are arranged between each adjacent vertical bars 2140. The horizontal bars 2130 extend in the length direction of the container 2000. All the vertical bars 2140 and all the horizontal bars 2130 in the same smoke exhaust grille 2100 are hollow and connected to form a smoke collecting channel 2110.

[0092] A plurality of smoke exhaust ports 2120 are provided on each side of the smoke exhaust grille 2100 arranged along the width direction of the container 2000. The smoke exhaust ports 2120 on each side of the smoke exhaust grille 2100 correspond one-to-one to all the smoke exhaust channels 1114 of the battery cluster row located on the side and connected to the smoke exhaust grille 2100. The smoke exhausted from the smoke exhaust channels 1114 of the battery cluster row located on the same side of the smoke exhaust grille 2100 enters the smoke collecting channel 2110 through the corresponding smoke exhaust ports 2120 (the direction of smoke flow is as shown in FIG. 2 ). Figure 5 The liquid is discharged after being gathered in the direction indicated by the arrow b.

[0093] It is worth mentioning that, in this embodiment, the length direction X of the container 2000 is consistent with that of the rack body 11 , the width direction Y of the container 2000 is consistent with that of the rack body 11 , and the height direction Z of the container 2000 is consistent with that of the rack body 11 .

[0094] The provision of the smoke exhaust grille 2100 can not only collect and discharge smoke, but also reduce the design of the complex smoke exhaust pipeline in the container 2000, simplify the structure of the container 2000, and reduce the manufacturing cost.
