Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a partitioned energy storage battery pack. Background Technology

[0002] As electricity demand increases, the size of energy storage battery packs is also gradually increasing. Large-scale energy storage systems often adopt container or modular designs for easier management.

[0003] When a battery cell experiences thermal runaway, the heat spreads over a wide area and can easily cause a large fire. Therefore, related technologies typically employ a partitioned sealing design inside the battery pack casing. This involves dividing the battery pack into multiple independent sealed spaces to separate multiple battery modules and reduce the impact on other battery cells.

[0004] However, when sampling the battery modules inside each independent sealed area, setting up a separate sampling device in each zone will occupy a lot of internal space of the battery pack, resulting in low utilization of internal space and reduced capacity. Furthermore, when one cell experiences thermal runaway, other cells are also easily affected, making it difficult to extinguish fires and vent thermal runaway, thus affecting the safety of the battery pack. Utility Model Content

[0005] The purpose of this invention is to provide a partitioned energy storage battery pack to solve the problems of low internal space utilization, poor fire extinguishing and thermal runaway exhaust effects.

[0009] Preferably, the end plate is connected to the two collection strips, and the fire vent and the exhaust vent are both located between the two collection strips.

[0010] Preferably, the end plate has a placement slot, a fire trough, and a discharge channel. The collection strip is connected to a connector, which is locked in the placement slot. The fire sprinkler head is placed in the fire trough, and the discharge channel is connected to the exhaust port.

[0011] Preferably, the first beam is provided with an explosion-proof isolation patch at the position corresponding to the vent hole, and the explosion-proof isolation patch covers the vent hole.

[0012] Preferably, the first beam has a receiving groove on the side facing the bottom surface of the lower housing, and the collecting plate is disposed in the receiving groove.

[0013] Preferably, the battery module is connected to a copper busbar, and the second beam has a fixing hole at the position corresponding to the copper busbar, so that the copper busbar passes through the fixing hole.

[0014] Preferably, the partitioned energy storage battery pack further includes a sealing strip connected to the upper cover to create a sealed connection between the upper cover and the lower housing.

[0015] Preferably, the partitioned energy storage battery pack further includes rivet nuts, which are disposed through the upper cover, the lower housing, and the sealing strip to limit the relative positions of the upper cover, the lower housing, and the sealing strip.

[0016] Preferably, the partitioned energy storage battery pack further includes a water-cooled plate, which is disposed on the side of the lower housing opposite to the upper cover.

[0017] The beneficial effects of this utility model are:

[0018] A partitioned energy storage battery pack includes multiple battery modules, a lower housing, a sampling component, and a top cover. The battery modules are connected to end plates. The lower housing is connected to a first beam and a second beam arranged in a cross configuration. The lower housing, the first beam, and the second beam enclose multiple accommodating spaces for housing the battery modules. The lower housing is equipped with an explosion-proof valve. The first beam has an exhaust chamber corresponding to each accommodating space, which is connected to the explosion-proof valve. A fire sprinkler is also provided on the first beam corresponding to each accommodating space. The sampling component includes sampling strips and sampling plates.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] See Figures 1 to 3 This utility model provides a partitioned energy storage battery pack, including multiple battery modules 1, a lower shell 2, a sampling component 3, and a top cover 4. The battery modules 1 are connected to end plates 11. The lower shell 2 is connected to a first beam 21 and a second beam 22 arranged in a cross configuration. The lower shell 2, the first beam 21, and the second beam 22 enclose multiple accommodating spaces 23 for accommodating the battery modules 1. The lower shell 2 is provided with an explosion-proof valve 24. The first beam 21 has an exhaust chamber 211 corresponding to the accommodating space 23, and the exhaust chamber 211 is connected to the explosion-proof valve 24. The first beam 21 is provided with a fire sprinkler head 212 corresponding to the accommodating space 23. The sampling component 3 includes sampling strips 31 and sampling plates 32. Multiple sampling strips 31 are provided, and the multiple sampling strips 31 are arranged corresponding to the accommodating spaces 23 and connected to the corresponding end plates 11. The sampling strips 31 are connected to the sampling plates 32, and the sampling plates 32 are arranged on the first beam 21. The top cover 4 is connected to the lower shell 2.

[0035] In this embodiment, eight battery modules 1 are provided, and eight corresponding accommodating spaces 23 are provided. The shape of the accommodating spaces 23 is adapted to the shape of the battery modules 1. An explosion-proof valve 24 is provided on the side wall connecting the lower housing 2 and the first beam 21 so that the exhaust chamber 211 can communicate with the explosion-proof valve 24. The extension direction of the exhaust chamber 211 is parallel to the extension direction of the first beam 21, and the exhaust chamber 211 is connected to each accommodating space 23. Fire sprinklers 212 are provided one-to-one with the accommodating spaces 23, and the fire sprinklers 212 are fixedly provided on the first beam 21.

[0036] Multiple acquisition strips 31 are respectively disposed within the accommodating space 23 so that the information of each battery module 1 can be transmitted to the acquisition board 32 through the acquisition strips 31. The acquisition board 32 is connected to a signal acquisition interface (not shown in the figure) at its end to realize the acquisition of information of the battery module 1. The acquisition board 32 is fixedly disposed on the first beam 21. The acquisition strips 31 are disposed against the side wall of the first beam 21 and located inside the accommodating space 23. The acquisition strips 31 are FPC (Flexible Printed Circuit) acquisition strips 31, and the acquisition board 32 is PCB (Printed Circuit Board) acquisition board 32. The upper cover 4 and the lower housing 2 are detachably connected. When the upper cover 4 and the lower housing 2 are connected, the accommodating space 23 is isolated from the outside world.

[0037] Thus, the first beam 21 and the second beam 22 divide the internal space of the lower housing 2 into multiple accommodating spaces 23, allowing each battery module 1 to be set up independently and reducing mutual interference. By integrating the fire sprinkler head 212, the exhaust chamber 211 and the acquisition plate 32 into the first beam 21, the internal space of the lower housing 2 can be saved, so that the accommodating spaces 23 can accommodate larger battery cells and increase the installed capacity. When the battery module 1 experiences thermal runaway, the fire sprinkler head 212 can spray fire extinguishing agent into the accommodating space 23 in a timely manner to extinguish the fire, and the high-temperature gas generated by thermal runaway can be discharged to the explosion-proof valve 24 in a timely manner through the exhaust chamber 211, improving the efficiency of fire extinguishing and thermal runaway exhaust, and improving the safety of the partitioned energy storage battery pack.

[0038] Understandably, the number of battery modules 1 can be adjusted according to actual needs, and can be four, six, ten, etc., which will not be listed in detail here.

[0039] It should be noted that the fire sprinkler head 212 can also be connected to a monitoring sensor. When the monitoring sensor detects that the battery module 1 has thermal runaway, it can promptly open the fire sprinkler head 212 and spray fire extinguishing agent. Setting up a monitoring sensor to monitor thermal runaway is existing technology and will not be elaborated here.

[0040] In some embodiments, the lower housing 2 is connected to an electrical compartment 25, and the information acquisition interface is located inside the electrical compartment 25. The electrical compartment 25 is provided with a liquid cooling interface 251, a fire protection interface 252 and a communication interface 253. The fire protection interface 252 is connected to a fire hose reel.

[0041] See Figure 1 and Figure 4 In some embodiments, the first beam 21 and the collection plate 32 both extend along the first direction X, the second beam 22 extends along the second direction Y, the side wall of the first beam 21 is provided with an exhaust hole 213 and a fire hole 214, the exhaust hole 213 communicates with the exhaust chamber 211, the fire nozzle 212 is disposed in the fire hole 214, and the exhaust hole 213 and the fire hole 214 are arranged at intervals along the third direction Z; the first direction X is the length direction of the lower housing 2, the second direction Y is the width direction of the lower housing 2, and the third direction Z is the height direction of the lower housing 2.

[0042] In this embodiment, the first beam 21 and the second beam 22 are symmetrically arranged inside the lower shell 2. The exhaust chamber 211 is arranged through the first beam 21. The exhaust hole 213 and the fire hole 214 are both round holes. The diameter of the exhaust hole 213 is larger than the diameter of the fire hole 214. The first beam 21 is also provided with a fire chamber 217. The extension direction of the fire chamber 217 is parallel to the extension direction of the exhaust chamber 211. A fire hole 214 and an exhaust hole 213 are correspondingly arranged in an accommodating space 23. The fire chamber 217 and the exhaust chamber 211 are separated.

[0043] Thus, by placing the fire vent 214 and the exhaust vent 213 on the side wall of the first beam 21, and placing the fire chamber 217 and the exhaust chamber 211 inside the first beam 21, the internal space of the first beam 21 can be fully utilized to achieve fire extinguishing and exhaust, avoiding the need to install related devices in the accommodating space 23 and thus reducing the installed capacity. The first beam 21 is relatively long and can be fully connected to each accommodating space 23, improving the space utilization rate. The fire vent 214 and the exhaust vent 213 are arranged at intervals along the third direction Z, which can avoid mutual interference between exhaust and fire extinguishing, and improve the safety and stability of the partitioned energy storage battery pack.

[0044] It is understandable that the locations of fire vent 214 and exhaust vent 213 can be adjusted according to actual needs, and will not be listed in detail here.

[0045] See Figure 4 and Figure 5 In some embodiments, the end plate 11 is connected to two collection strips 31, and the fire vent 214 (see reference) Figure 1 Both the fire vent 214 and the exhaust vent 213 are located between the two collection strips 31. In this embodiment, both collection strips 31 are inserted into the end plate 11 and are symmetrically arranged on both sides of the fire vent 214 and the exhaust vent 213.

[0046] In this way, the position of the side wall of the first beam 21 can be used reasonably, reducing interference between various structures. This makes the position distribution of the data collection strip 31, fire hole 214 and exhaust hole 213 in the accommodating space 23 more compact. While realizing the data collection of the battery module 1, it avoids the extra space occupied due to position conflicts, improves the space utilization rate inside the partitioned energy storage battery pack, and thus increases the installed capacity.

[0047] It is understandable that the relative positions of the collection strip 31 with the fire vent 214 and the exhaust vent 213 can be adjusted according to actual needs, which will not be elaborated here.

[0048] See Figures 5 to 7 In some embodiments, the end plate 11 is provided with a placement groove 111, a fire trough 112 and a discharge channel 113. The collection strip 31 is connected to a connector 311, which is locked in the placement groove 111. The fire nozzle 212 is disposed in the fire trough 112, and the discharge channel 113 is connected to the exhaust port 213.

[0049] In this embodiment, the shape of the placement groove 111 is adapted to the shape of the connector 311 so that the connector 311 can be plugged into the battery module 1. The fire trough 112 is set at the position corresponding to the fire sprinkler head 212. The discharge channel 113 is set below the fire trough 112 and the placement groove 111. The discharge channel 113 is set through the end plate 11 so that when the battery module thermally runs away, the gas can be discharged into the discharge hole through the discharge channel 113 in a timely manner, and discharged into the explosion-proof valve 24 through the discharge chamber.

[0050] Thus, the placement slot 111 can restrict the position of the connector 311, making the information collection of the battery module 1 by the collection strip 31 more stable, and protecting the connector 311. This makes the connection between the end plate 11 and the first beam 21 more stable and compact, reducing the volume occupied by the sampling component 3 in the accommodating space 23 and improving space utilization. The fire trough 112 is set to correspond to the fire sprinkler 212, which can facilitate the fire sprinkler 212 to accurately spray the fire extinguishing agent and improve the fire extinguishing effect. When the battery module 1 thermally runs away, the generated gas can be delivered to the exhaust port 213 in a timely manner through the exhaust channel 113, avoiding the accumulation of gas in the accommodating space 23 and improving the safety and stability of the partitioned energy storage battery pack.

[0051] See Figure 5 In some embodiments, an explosion-proof isolation patch 215 is provided at the position of the first beam 21 corresponding to the vent 213, and the explosion-proof isolation patch 215 covers the vent 213.

[0052] In this embodiment, the explosion-proof isolation patch 215 is a thin film structure. When a battery module 1 installed in a certain accommodating space 23 experiences thermal runaway, the excessive pressure in the accommodating space 23 causes the explosion-proof isolation patch 215 to rupture, allowing the gas to be discharged to the outside through the exhaust chamber 211 and the explosion-proof valve 24. At the same time, other normally functioning battery modules 1 can be protected by the explosion-proof isolation patch 215, preventing gas from moving within each accommodating space 23 and improving the safety of the partitioned energy storage battery pack.

[0053] See Figure 3 and Figure 4 In some embodiments, the first beam 21 has a receiving groove 216 on the side facing the bottom surface of the lower housing 2, and the collection plate 32 is disposed in the receiving groove 216.

[0054] In this embodiment, the shape of the receiving groove 216 is adapted to the shape of the collecting plate 32. The receiving groove 216 and the exhaust chamber 211 are isolated to avoid mutual interference. Multiple collecting strips 31 are symmetrically arranged on both sides of the receiving groove 216. The bottom of the first beam 21 is provided with sealant 218 (not shown in the figure) to make the first beam 21 and the bottom surface of the lower housing 2 sealed together.

[0055] Thus, by setting a receiving groove 216 in the first beam 21 to accommodate the acquisition plate 32, the internal space of the first beam 21 can be fully utilized, making the structure more compact. No additional space is needed for installing the acquisition plate 32, reducing the space occupied by the sampling component 3, improving the space utilization rate inside the partitioned energy storage battery pack, increasing the installed capacity, and isolating it from the exhaust chamber 211 can reduce the impact of gases emitted during thermal runaway on the acquisition plate 32, improving the safety and stability of the partitioned energy storage battery pack.

[0056] See Figure 2 In some embodiments, the battery module 1 is connected to a copper busbar 12, and the second beam 22 has a fixing hole 221 at the position corresponding to the copper busbar 12, so that the copper busbar 12 passes through the fixing hole 221.

[0057] In this embodiment, the two ends of the copper busbar 12 are respectively connected to two battery modules 1 arranged adjacent to each other in the first direction X. The copper busbar 12 is fitted with a sealing ring made of rubber material. The sealing ring is locked in the fixing hole 221 to restrict the position of the copper busbar 12 and make the copper busbar 12 and the second beam 22 insulated and sealed.

[0058] Thus, by opening fixing holes 221 on the second beam 22, the fixing device used to fix the copper busbar 12 can be saved. There is no need to set up a separate support or clearance space for the copper busbar 12, which improves the space utilization rate inside the partitioned energy storage battery pack. It can also limit the position of the copper busbar 12, prevent the copper busbar 12 from shaking, and improve the safety and stability of the partitioned energy storage battery pack.

[0059] It is understandable that the sealing ring can also be made of other insulating materials, which will not be elaborated here.

[0060] See Figure 7 In some embodiments, the partitioned energy storage battery pack further includes a sealing strip 5, which is connected to the upper cover 4 to seal the upper cover 4 and the lower housing 2. Further, in some embodiments, the partitioned energy storage battery pack also includes a rivet nut 6, which passes through the upper cover 4, the lower housing 2, and the sealing strip 5 to limit the relative positions of the upper cover 4, the lower housing 2, and the sealing strip 5.

[0061] In this embodiment, the sealing strip 5 abuts against the lower housing 2 and the upper cover 4 on both sides respectively. Multiple rivet nuts 6 are provided, and the multiple rivet nuts 6 are spaced apart along the extension direction of the sealing strip 5 so as to securely connect the upper cover 4, the sealing strip 5 and the lower housing 2.

[0062] In this way, the sealing strip 5 can prevent gas in the accommodating space 23 from leaking to other areas, ensure that the gas generated during thermal runaway can be discharged through the exhaust chamber 211 and the explosion-proof valve 24, and prevent external impurities from entering the accommodating space 23 and affecting the battery module 1. The rivet nut 6 can improve the connection stability between the upper cover 4 and the lower housing 2, thereby improving the safety of the partitioned energy storage battery pack.

[0063] See Figure 3 and Figure 8 In some embodiments, the partitioned energy storage battery pack further includes a water-cooled plate 7, which is disposed on the side of the lower housing 2 opposite to the upper cover 4. In this embodiment, the water-cooled plate 7 is detachably connected to the lower housing 2 by bolts, and the liquid cooling interface 251 is connected to the water-cooled plate 7.

[0064] In this way, the water-cooled plate 7 can dissipate heat from the lower housing 2 and the internal battery module 1, removing the heat generated by the battery module 1 during operation, avoiding thermal runaway caused by excessive local temperature, and reducing the risk of fire.

[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
