Description

Technical Field

[0002] The energy storage system is generally composed of multiple energy storage modules. The energy storage module includes multiple battery cell groups and a shell for accommodating the battery cell groups. The bottom of the shell is generally provided with a base and a liquid cooling plate. The battery cell groups are fitted with the liquid cooling plate to dissipate heat through the liquid cooling plate. In order to ensure that the liquid cooling plate can take away the heat of the battery cell group in time, the liquid cooling plate needs to fit tightly with the battery cell group. During use, the energy storage module is affected by the temperature of the external environment and the cooling effect of its own cooling system, which causes the temperature inside the energy storage module to drop sharply, resulting in a decrease in the temperature of the base. As a result, the outer wall of the base is prone to condensation. When multiple energy storage modules are placed in multiple layers, the condensed water on the upper base is prone to dripping to the energy storage modules on the lower layer, thus posing a safety hazard.

The metal strip is suitable for being fixedly connected to the first flange, and the second flange is clamped between the first flange and the metal strip.

[0015] From the above description of the utility model and its preferred embodiments, it can be seen that, compared with the prior art, the technical solution of the utility model and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0016] In technical solution one, the load-bearing bottom wall is provided with a bottom surface and a plurality of convex strips protruding from the bottom surface. The provision of the convex strips can increase the strength of the base on the one hand, and can support the thermal insulation cotton and form a first air insulation layer between the thermal insulation cotton and the bottom surface on the other hand. In this way, when the liquid cooling plate is supported on the thermal insulation cotton, the thermal insulation cotton and the first air insulation layer can realize double-layer insulation between the liquid cooling plate and the bottom surface of the base. When the battery cell is placed on the liquid cooling plate, the formation of condensed water in the base when the battery cell temperature is low can be effectively avoided or reduced, thereby improving the safety of the energy storage module. Among them, in addition to the thermal insulation effect, the thermal insulation cotton can also form a buffer for the liquid cooling plate when it is installed.

[0017] In technical solution two, the positioning part is higher than the convex strip, and the thermal insulation cotton avoids the positioning parts. Therefore, when the thermal insulation cotton is placed on the bottom bracket, the thermal insulation cotton can be positioned by the position of the positioning part, and the different heights of the positioning part and the convex strip are also designed to match the uneven bottom surface of the liquid cooling plate, thereby ensuring the flatness of the upper surface of the liquid cooling plate, making the liquid cooling plate suitable for fitting with the battery cell.

[0018] In the third technical solution, the thermal insulation cotton is suitable for supporting the outer surface of the bottom wall of the water tank, so that the flow channel part with large temperature change in the liquid cooling plate can be well insulated, thereby effectively improving the condensation phenomenon, and the bottom wall of the water tank protrudes from the lower surface of the lower cold plate and is supported by the thermal insulation cotton, which can prevent the water tank from being deformed by impact; the lower cold plate forms a stamping groove with an opening downward, and the stamping groove is suitable for forming a second air insulation layer between the thermal insulation cotton. In actual application, the stamping groove and the water tank are integrally processed and formed, and the stamping groove and the water tank are completely avoided. The concave and convex structure of the lower cold plate is used here to form the second air insulation layer, thereby making full use of the structure of the lower cold plate itself to form the second air insulation layer, and the process is simpler, and in this way, a three-layer insulation structure (first air insulation layer, thermal insulation cotton layer and second air insulation layer) is formed between the part outside the flow channel in the liquid cooling plate and the bottom surface of the bottom bracket, thereby forming good insulation between the part outside the flow channel in the liquid cooling plate and the bottom surface.

[0019] In technical solution four, each energy storage cell is arranged along a first direction and extends along a second direction perpendicular to the first direction, and each convex strip is arranged along the second direction and extends along the first direction, so that each convex strip can support multiple energy storage cells, making the supporting assembly more stable when supporting the energy storage cells; the positioning portion is protruding on the convex strip, which is conducive to ensuring that the positioning portion is higher than the convex strip and thus positioning the thermal insulation cotton, wherein the provision of multiple positioning portions ensures multi-point support for the liquid cooling plate, which is conducive to maintaining the flatness of the upper surface of the liquid cooling plate.

[0020] In technical solution five, the positioning parts are arranged in a rectangular array, and the thermal insulation cotton is provided with a strip opening extending along the second direction corresponding to each positioning groove. The positioning part is suitable for passing through the strip opening to support the positioning groove, so that at least two strip openings are formed on the thermal insulation cotton, which is conducive to positioning the thermal insulation cotton. In addition, it is simpler to form a strip opening directly on the thermal insulation cotton corresponding to the positioning groove instead of an opening for each positioning part.

[0021] In technical solution six, during installation, the liquid inlet joint is first welded to the upper cold plate, the liquid outlet joint is welded to the upper cold plate, and then the liquid inlet joint and the liquid outlet joint are respectively passed through the first through hole and the second through hole. The liquid inlet joint and the liquid outlet joint are directly welded to the upper cold plate to achieve connection between the liquid inlet port and the liquid outlet port and the outside, which is not prone to leakage and avoids leakage caused by too many interfaces when multiple adapter tubes are connected.

[0022] In Technical Solution 7, the provision of the first seal and the second seal further avoids leakage at the first through hole and the second through hole, is beneficial to processing, and enables the support assembly to be applied to the energy storage module so that a closed structure is easily formed inside the energy storage module, thereby avoiding the formation of condensed water inside the energy storage module.

[0023] Technical solution eight has the technical advantages of any one of technical solutions one to seven.

[0024] In technical solution nine, the second flange is sealed and fixedly connected to the first flange so that the top cover and the supporting assembly cooperate to form a receiving cavity suitable for receiving the energy storage cell, so that the receiving cavity is relatively closed, condensation water is not easily formed in the receiving cavity, and the protection level of the energy storage module is improved.

[0025] In Technical Solution 10, since the top cover is made of plastic material, compared with metal material, plastic material is not easy to form condensation water, but at the same time the connection between the plastic material and the bottom support is not stable. In this technical solution, the metal pressure strip is suitable for being fixed with the first flange, and the second flange is clamped between the first flange and the pressure strip, which ensures the stable connection between the top cover and the bottom support, and makes the accommodating cavity relatively closed, and condensation water is not easy to form in the accommodating cavity, thereby improving the protection level of the energy storage module.

[0045] See also Figure 1-4 , Figure 1-4 A supporting assembly is shown, which is used for an energy storage module 100. The energy storage module 100 includes a plurality of battery cell packages supported on the supporting assembly. Each battery cell package includes N energy storage batteries 50 arranged along a first direction and extending along a second direction perpendicular to the first direction. The length direction of the energy storage batteries 50 is the second direction, and the width direction of the energy storage batteries 50 is the first direction. Figure 1-4 In the example, the first direction is the left-right direction, and the second direction is the front-back direction. N is a positive integer greater than 1, Figure 2 In the embodiment, the energy storage module 100 includes two battery cell packages arranged along the second direction, and each battery cell package includes four energy storage cells 50 .

[0046] The supporting assembly includes a base 20 , a heat-insulating foam 30 and a liquid cooling plate 10 . Figure 3-4 Also shown are structures such as a support beam 40 that supports the energy storage cell 50 .

[0047] See also Figure 5 The bottom bracket 20 is an open box-shaped structure with a first flange 28, which is provided with a load-bearing bottom wall 21, and the load-bearing bottom wall 21 is provided with a bottom surface 22 and a plurality of convex strips 23 protruding from the bottom surface 22. Each convex strip 23 is arranged along the second direction and extends along the first direction; except for the convex strips 23 at the front and rear ends of the bottom bracket 20, at least two convex blocks arranged along the first direction are protruding from each middle convex strip 23, and the convex blocks form a positioning portion 24, that is, the positioning portion 24 is protruding from the convex strip 23, wherein the convex blocks on each convex strip 23 correspond to each other so that each positioning portion 24 is arranged in a rectangular array. The convex strip 23 and the convex blocks are preferably integrally formed with the bottom surface 22. It should be understood that in other embodiments, the positioning portion 24 may not be formed on the convex strip 23, as long as it protrudes relative to the bottom surface 22 and is higher than the convex strip 23. The arrangement of the convex strip 23 enables each convex strip 23 to support multiple energy storage cells 50, so that the supporting assembly is more stable when supporting the energy storage cells 50. The provision of multiple positioning portions 24 ensures multi-point support for the liquid cooling plate 10 , which is beneficial for maintaining the flatness of the upper surface of the liquid cooling plate 10 .

[0048] A connection structure connected to the liquid cooling plate 10 is also formed on the bottom bracket 20, and the top surface of the connection structure is flush with the top surface of the positioning portion 24. In this embodiment, the connection structure includes a plurality of connection seats 25 and two connection bars 26. The connection seats 25 are distributed in the intervals of the positioning portions 24 arranged along the second direction. A threaded hole is formed on the connection seat 25, and the two connection bars 26 are distributed on both sides of the load-bearing bottom wall 21 along the first direction and extend along the second direction. In this embodiment, the two connection bars 26 are respectively located on both sides of each convex strip 23 along the first direction. A plurality of connection portions 261 are spaced apart on the connection bar 26 along its length direction, and the connection portion 261 is in the form of a threaded hole in this embodiment.

[0049] See also Figure 6-9 The heat-insulating cotton 30 is supported on each convex strip 23 to form a first air heat-insulating layer 001 between the bottom surface 22. In this embodiment, when the heat-insulating cotton 30 is supported on the convex strip 23, each positioning portion 24, each connecting seat 25 and two connecting strips 26 should be avoided. Figure 6In the embodiment, the heat insulation cotton 30 forms a strip-shaped opening 31 extending along the second direction corresponding to each positioning portion 24 arranged along the second direction to avoid the corresponding positioning portion 24 and the connecting seat 25. The width of the heat insulation cotton 30 along the first direction is less than the spacing between the two connecting strips 26 to avoid the two connecting strips 26. The liquid cooling plate 10 is supported on the heat insulation cotton 30 and avoids the heat insulation cotton 30 being fixedly connected to the bottom bracket 20. In this embodiment, the liquid cooling plate 10 is mainly locked with the connecting seat 25 and the connecting strip 26. Therefore, the liquid cooling plate 10 is also supported on the positioning portion 24, the connecting seat 25 and the connecting strip 26.

[0050] See also Figure 10-11 The liquid cooling plate 10 includes an upper cooling plate 11 and a lower cooling plate 12. The lower cooling plate 12 is punched to form a plurality of water troughs 121 with openings facing upward and a plurality of stamping grooves 122 with openings facing downward. The upper cooling plate 11 is sealed and fixedly connected to the lower cooling plate 12 so that the water troughs 121 cooperate with the upper cooling plate 11 to form a flow channel. The thermal insulation cotton 30 is suitable for supporting the outer surface of the bottom wall of the water trough 121. The stamping grooves 122 are suitable for forming a second air insulation layer 002 between the thermal insulation cotton 30. The stamping grooves 122 include positioning grooves 123 extending along the second direction, so the thermal insulation cotton 30 is provided with a strip opening 31 extending along the second direction corresponding to each positioning groove 123. The positioning portion 24 is suitable for passing through the strip opening 31 to support the positioning groove 123. In this embodiment, three strip openings 31 are formed on the thermal insulation cotton 30, which is conducive to positioning the thermal insulation cotton 30. In addition, it is simpler to form a strip opening 31 directly corresponding to the positioning groove 123 on the thermal insulation cotton 30 instead of opening an opening for each positioning portion 24.

[0051] See also Fig.11 The liquid cooling plate 10 has a plurality of first connection holes 1231 arranged at intervals along the second direction on the bottom wall of each positioning groove 123, and a plurality of second connection holes 1232 arranged at intervals along the second direction on both sides of the liquid cooling plate 10 along the first direction, wherein each first connection hole 1231 corresponds to each connection seat 25 one by one, and each second connection hole 1232 corresponds to each connection portion 261 one by one, so that the connection seat 25 and the connection portion 261 are respectively suitable for being locked with the first connection hole 1231 and the second connection hole 1232. The second connection holes 1232 on both sides of the liquid cooling plate 10 are symmetrically arranged, and each second connection hole 1232 is at least partially aligned with the first connection hole 1231 along the first direction.

[0052] See also Fig.10 A liquid inlet port 01 and a liquid outlet port 02 connected to the flow channel are arranged along the first direction on one side of the upper cold plate 11 along the second direction. The liquid inlet port 01 and the liquid outlet port 02 of the liquid cold plate 10 are connected to the outside through a liquid inlet joint 61 and a liquid outlet joint 62 respectively, and are sealed with the base 20 through a first seal 63 and a second seal 64 respectively.

[0053] Specifically, see Figure 3-7The bottom bracket 20 is provided with a first side wall 27 close to the liquid inlet port 01 and the liquid outlet port 02. The heat preservation cotton 30 and the liquid cooling plate 10 are placed corresponding to the bottom of the bottom bracket 20. The first side wall 27 is provided with a first through hole 271 and a second through hole 272 corresponding to the liquid inlet port 01 and the liquid outlet port 02 respectively along the second direction; one end of the liquid inlet joint 61 is welded to the upper cold plate 11 corresponding to the liquid inlet port 01, and the other end passes through the first through hole 271 and extends out of the bottom bracket 20; one end of the liquid outlet joint is welded to the upper cold plate 11 corresponding to the liquid outlet port 02, and the other end passes through the second through hole 272 and extends out of the bottom bracket 20. The first seal 63 and the second seal 64 are both sealed and fixedly connected to the inner surface of the first side wall 27, and the liquid inlet joint 61 and the liquid outlet joint 62 are also suitable for passing through the first seal 63 and the second seal 64 respectively.

[0054] During installation, first weld the liquid inlet connector 61 to the upper cold plate 11, weld the liquid outlet connector 62 to the upper cold plate 11, then sequentially pass the liquid inlet connector 61 through the first seal 63 and the first through hole 271 and lock it with the first side wall 27, and sequentially pass the liquid outlet connector 62 through the second seal 64 and the second through hole 272 and lock it with the first side wall 27. The liquid inlet connector 61 and the liquid outlet connector are directly welded to the upper cold plate 11 to realize the connection between the liquid inlet port 01 and the liquid outlet port 02 and the outside, which is not easy to leak, and avoids the leakage problem caused by too many interfaces when multiple transfer tubes are transferred. The provision of the first seal 63 and the second seal 64 further avoids leakage at the first through hole 271 and the second through hole 272, is conducive to processing, and makes it easy to form a closed structure inside the energy storage module 100, avoiding the formation of condensed water inside the energy storage module 100.

[0055] In this embodiment, the arrangement of the convex strips 23 can increase the strength of the bottom bracket 20 on the one hand, and can support the thermal insulation cotton 30 on the other hand and form a first air insulation layer 001 between the thermal insulation cotton 30 and the bottom surface 22. In this way, when the liquid cooling plate 10 is supported on the thermal insulation cotton 30, the thermal insulation cotton 30 and the first air insulation layer 001 can realize double-layer insulation between the liquid cooling plate 10 and the bottom surface 22 of the bottom bracket 20. When a battery cell is placed on the liquid cooling plate 10, condensation water can be effectively avoided or reduced in the bottom bracket 20 when the battery cell temperature is low, thereby improving the energy storage module. The safety of the block 100; wherein, the thermal insulation cotton 30, in addition to the heat insulation effect, can also form a buffer for the liquid cooling plate 10 when it is installed; the positioning portion 24 is higher than the convex strip 23, and the thermal insulation cotton 30 avoids each positioning portion 24. Therefore, when the thermal insulation cotton 30 is placed on the base 20, the thermal insulation cotton 30 can be positioned by the position of the positioning portion 24, and the different heights of the positioning portion 24 and the convex strip 23 are also based on the matching design of the uneven bottom surface 22 of the liquid cooling plate 10, thereby ensuring the flatness of the upper surface of the liquid cooling plate 10, so that the liquid cooling plate 10 is suitable for fitting with the battery cell. The thermal insulation cotton 30 is suitable for supporting the outer surface of the bottom wall of the water tank 121, so that the flow channel part with large temperature change in the liquid cooling plate 10 can be well insulated, thereby effectively improving the condensation phenomenon, and the bottom wall of the water tank 121 protrudes from the lower surface of the lower cold plate 12, supported by the thermal insulation cotton 30, which can prevent the water tank 121 from being impacted and deformed; the lower cold plate 12 forms a stamping groove 122 with an opening downward, and the stamping groove 122 is suitable for forming a second air insulation layer 002 between the thermal insulation cotton 30. In actual application, the stamping groove 122 and the water tank 121 are processed into an integral body. The stamping groove 122 and the water trough 121 are completely avoided. The concave-convex structure of the lower cold plate 12 is used here to form the second air insulation layer 002, thereby making full use of the structure of the lower cold plate 12 itself to form the second air insulation layer 002. The process is simpler, and a three-layer insulation structure (a first air insulation layer 001, a thermal insulation cotton layer 30 and a second air insulation layer 002) is formed between the portion outside the flow channel of the liquid cooling plate 10 and the bottom surface 22 of the base 20, thereby forming good insulation between the portion outside the flow channel of the liquid cooling plate 10 and the bottom surface 22.

[0056] In this embodiment, both sides of the liquid cooling plate 10 can be supported and fixed by the connecting strips 26, the middle part of the liquid cooling plate 10 is supported by the positioning portion 24 and supported and fixed by the connecting seat 25, and the front and rear sides of the liquid cooling plate 10 can be bonded to the base 20 by structural adhesive, so that the liquid cooling plate 10 and the base 20 form a multi-point support and multi-point fixed structure as a whole, which not only has low process cost but also has a stable structure.

[0057] This embodiment also provides an energy storage module 100, which adopts the middle support assembly of Embodiment 1 and has the same advantages as Embodiment 1.

[0058] In practical applications, see Figure 1-2The energy storage module 100 further includes a top cover 70 and a metal pressure strip 80. The bottom bracket 20 is an open box body with a first flange 28 and is made of metal material. The top cover 70 is an open box body with a second flange 71 and is made of plastic material. The second flange 71 is suitable for sealing and fixing with the first flange 28 so that the top cover 70 and the supporting assembly cooperate to form a receiving cavity suitable for accommodating the energy storage battery cell 50. Since the top cover 70 is made of plastic material and the bottom bracket 20 is made of metal material, the first flange 28 and the second flange 71 are directly connected. Due to the difference in materials, there is still an instability problem. In this embodiment, the metal pressure strip 80 is suitable for fixing with the first flange 28. The second flange 71 is sandwiched between the first flange 28 and the pressure strip and is sealed and abutted with the first flange 28 so that the top cover 70 and the supporting assembly cooperate to form a receiving cavity suitable for accommodating the energy storage battery cell 50. The above arrangement makes the receiving cavity relatively closed, and condensation water is not easy to form in the receiving cavity, thereby improving the protection level of the energy storage module 100.

[0059] It should be understood that in actual applications, the energy storage module 100 will also include electrical components such as copper busbars, terminal blocks, safety switches, sensors, etc. The battery cell groups can be connected in series through the copper busbars and then electrically connected to external devices through the terminal blocks. In actual applications, a sealing structure is formed at the interface of the top cover 70 to ensure sealing.

[0060] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
