Description

Technical Field

[0001] This application relates to the field of energy storage equipment technology, and in particular to a housing module and an energy storage device. Background Technology

[0002] Energy storage devices are generally equipped with air valves to improve the problem of water vapor entering the device. However, it is impossible to completely prevent water vapor from entering. Some water vapor will still enter the device through the air valves, causing it to condense and adhere to the battery cells inside the device. Over time, the accumulation of condensate can corrode the battery cells and even cause short circuits and other safety malfunctions, affecting the lifespan of the energy storage device. Utility Model Content

[0003] In view of this, this application provides a housing module and an energy storage device that can improve the service life of the energy storage device.

[0004] An embodiment of this application provides a housing module, including a mounting housing and a drain valve. The mounting housing has an installation space, and a drain hole is provided at the bottom of the mounting housing, which communicates with the installation space. The drain valve is disposed at the drain hole and includes a valve stem and a valve core. The valve stem is connected to the mounting housing, and the valve core is connected to the valve stem. The valve core has a draining state with the drain hole open and a sealing state with the drain hole blocked. When the valve core is in the sealing state, the edge of the valve core abuts against the mounting housing, so that the valve core and the mounting housing form a closed space, and the drain hole is located within the closed space. When the valve core is in the draining state, the edge of the valve core separates from the mounting housing, so that the closed space is connected to the external environment.

[0005] The aforementioned housing module can be used in energy storage devices. The battery cells of the energy storage device can be placed in the installation space of the housing. By providing a drain hole and a drain valve at the bottom of the housing, the drain valve can open or close the drain hole, so that the condensate accumulated in the installation space can be discharged to the outside of the housing through the drain hole when the drain valve is open. This improves the problem of corrosion damage to the battery cells caused by the accumulation of condensate in the installation space, thereby extending the service life of the energy storage device.

[0006] In at least one embodiment, the valve core is an umbrella-shaped structure, with the middle part of the umbrella-shaped structure connected to the valve stem. When the valve core is in a sealed state, the edge of the umbrella-shaped structure abuts against the mounting housing.

[0007] By setting the valve core to an umbrella-shaped structure, the connection between the valve core and the mounting housing will be tighter when the edge of the umbrella-shaped structure abuts against the mounting housing due to the certain curvature of the umbrella-shaped structure.

[0008] In at least one embodiment, the valve core is disposed on the outside of the mounting housing, the valve core is an elastic structure, and is configured such that the elastic structure undergoes elastic deformation under water pressure to separate from the mounting housing.

[0009] By setting the valve core as an elastic structure and placing it on the outside of the mounting housing, when a predetermined weight of water accumulates in the enclosed space, the elastic structure deforms due to the gravity of the water, causing the edge of the valve core to separate from the mounting housing, thereby opening the drain hole and draining the water through the drain hole. After the water is drained to the outside of the mounting space, due to the disappearance of gravity, the elastic structure returns to the sealed state through its own elasticity. It can be seen that the above-mentioned setting of the valve core can realize the automatic switching between the sealed state and the draining state of the valve core, improving the timeliness of drainage of the housing module.

[0010] In at least one embodiment, the valve core is provided with valve core reinforcing ribs, which are located on the inner surface of the valve core near the mounting housing. The valve core reinforcing ribs are annular structures arranged with the center of the umbrella-shaped structure as the center.

[0011] By setting a ring-shaped reinforcing rib for the valve core, the structural strength of the valve core can be enhanced, and the problem of the valve core being unable to automatically return to its original shape when it deforms can be improved.

[0012] In at least one embodiment, the valve core is provided with abutting ribs, which are disposed at the edge of the valve core and abut against the mounting housing; the abutting ribs are annular structures arranged with the center of the umbrella-shaped structure as the center.

[0013] By setting an annular abutment rib at the edge of the valve core, a structure protruding towards the mounting housing is formed at the edge of the valve core. When the abutment rib abuts against the mounting housing, the contact between the valve core and the mounting housing can be made tighter.

[0014] In at least one embodiment, multiple drain holes are provided, which are spaced around the valve stem and are all located on the side of the valve core near the enclosed space.

[0015] By setting multiple drain holes, condensate in the installation space can flow from various positions around the valve core into the closed space enclosed by the valve core and the mounting housing, thereby increasing the accumulation rate of condensate in the closed space and thus improving drainage efficiency and reliability.

[0016] In at least one embodiment, the mounting housing has a water storage tank disposed at the bottom of the mounting housing, the water storage tank having a bottom wall and a drain hole disposed at the bottom wall.

[0017] By setting a water storage tank at the bottom of the mounting housing and setting the drain hole at the bottom wall of the water storage tank, a height difference is formed between the bottom wall of the water storage tank and the bottom wall of the mounting housing located around the water storage tank, so that the condensate can flow smoothly to the drain hole.

[0018] In at least one embodiment, the mounting housing has a flow guide groove disposed at the bottom of the mounting housing, the flow guide groove being disposed around the water storage tank and communicating with the water storage tank.

[0019] The condensate in the installation space is guided to the water storage tank through the diversion channel, so that the condensate can flow smoothly to the drain hole.

[0020] In at least one embodiment, the flow channel includes two first flow channel sections, which are arranged opposite to each other and are both connected to the water storage tank.

[0021] The condensate is diverted from two different directions to the water storage tank through two first diversion channels, thereby improving the diversion effect of the condensate.

[0022] In at least one embodiment, two drain valves and two water storage tanks are provided, with the two drain valves and two water storage tanks arranged in a one-to-one correspondence. The distribution direction of the two water storage tanks is perpendicular to the distribution direction of the two first guide channel sections, and each water storage tank is located between the two first guide channel sections. Each first guide channel section includes a first channel section and a second channel section. The first channel section has a first guide surface, and the second channel section has a second guide surface. The first guide surface and the second guide surface are respectively inclined toward the bottom wall of the two water storage tanks.

[0023] By setting up two water storage tanks, the amount of condensate collected can be increased. Furthermore, the first diversion channel section is provided with a first tank section and a second tank section to divert the condensate into the two water storage tanks respectively.

[0024] In at least one embodiment, the bottom of the mounting housing is provided with two water-blocking ribs, the distribution direction of the two water-blocking ribs is the same as the distribution direction of the two first guide channel sections, each water-blocking rib is connected to the mounting housing and extends to the water storage tank; the guide channel includes a second guide channel section, the two water-blocking ribs and the inner sidewall of the mounting housing form a second guide channel section, and the second guide channel section is connected to the water storage tank.

[0025] By setting two water-blocking ribs and dividing the diversion channel into a second diversion channel section and a first diversion channel section, when the condensate is diverted in the first diversion channel section, the condensate will not flow to the outside of the water storage tank due to the obstruction and diversion of the water-blocking ribs. Furthermore, the condensate in the remaining space of the installation area is diverted into the water storage tank through the second diversion channel section, thereby improving the collection effect of condensate.

[0026] In at least one embodiment, the housing module further includes housing reinforcing ribs disposed at the bottom of the second guide channel section.

[0027] The structural strength of the bottom of the mounting housing is enhanced by setting housing reinforcing ribs at the bottom of the mounting housing.

[0028] In at least one embodiment, the housing module further includes a protective housing disposed within the installation space, the protective housing having a sealed chamber for accommodating the battery cell, and the drain valve and the protective housing being spaced apart.

[0029] By placing the battery cells within the sealed chamber of the protective housing, some moisture can be blocked when it enters the installation space of the housing, reducing direct contact between moisture and the battery cells. Combined with the installation of drainage holes and valves, when water accumulates to a certain level in the installation space, condensate can be promptly removed through the drainage holes and valves, reducing the damage of condensate to other internal components of the energy storage device and thus extending the service life of other internal components.

[0030] On the other hand, one embodiment of this application provides an energy storage device, including a battery cell and the aforementioned housing module, wherein the battery cell is disposed within the housing module.

[0031] By applying the aforementioned housing module to energy storage devices, the battery cells of the energy storage devices can be placed in the installation space of the housing. By providing a drain hole and a drain valve at the bottom of the housing, the drain valve can open or close the drain hole, so that the condensate accumulated in the installation space can be discharged to the outside of the housing through the drain hole when the drain valve is open. This improves the problem of corrosion damage to the battery cells caused by the accumulation of condensate in the installation space, thereby extending the service life of the energy storage devices.

[0044] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0046] In related technologies, energy storage devices include structures such as battery cells and housing modules. The battery cells are installed inside the housing modules. To reduce the risk of combustion and explosion, the interior of energy storage devices is generally able to exchange gases with the external environment for heat dissipation. However, since energy storage devices operate in humid environments, moisture can easily seep into their interiors. To address this, energy storage devices are typically equipped with air valves to mitigate the problem of moisture entering the device. However, these valves cannot completely prevent moisture from entering; some moisture still manages to enter the device and condense on the battery cells. Over time, this accumulation of condensate can corrode the battery cells, potentially causing short circuits and other safety malfunctions, thus affecting the lifespan of the energy storage device.

[0047] An embodiment of this application provides a housing module, including a mounting housing and a drain valve. The mounting housing has an installation space, and a drain hole is provided at the bottom of the mounting housing, communicating with the installation space. The drain valve is disposed at the drain hole and includes a valve stem and a valve core. The valve stem is connected to the mounting housing, and the valve core is connected to the valve stem. The valve core has a draining state with the drain hole open and a sealing state with the drain hole blocked. When the valve core is in the sealing state, the edge of the valve core abuts against the mounting housing, so that the valve core and the mounting housing form a closed space, and the drain hole is located within the closed space. When the valve core is in the draining state, the edge of the valve core is separated from the mounting housing.

[0048] The aforementioned housing module can be used in energy storage devices. The battery cells of the energy storage device can be placed in the installation space of the housing. By providing a drain hole and a drain valve at the bottom of the housing, the drain valve can open or close the drain hole, so that the condensate accumulated in the installation space can be discharged to the outside of the housing through the drain hole when the drain valve is open. This improves the problem of corrosion damage to the battery cells caused by the accumulation of condensate in the installation space, thereby extending the service life of the energy storage device.

[0049] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0050] Please see Figure 1 and Figure 2 One embodiment of this application provides a housing module 100 and an energy storage device 200.

[0051] In some embodiments, the energy storage device 200 has the functions of storing and discharging electricity for use as backup power for homes, production units, outdoor work, and outdoor recreation. Specifically, the energy storage device 200 includes a battery cell 201 to store electrical energy.

[0052] In some embodiments, cell 201 includes a plurality of cell components.

[0053] In some embodiments, the energy storage device 200 includes a power conversion module (not shown). The power conversion module is electrically connected to the battery cell 201 and is used to control the AC / DC conversion of the output current of the battery cell 201. The energy storage device 200 equipped with the power conversion module can be a small portable power supply, a residential energy storage power supply, an industrial or commercial energy storage power supply, or a containerized energy storage power supply, etc.

[0054] In some embodiments, the power conversion module may be omitted. An energy storage device 200 without a power conversion module can be used independently. An energy storage device 200 without a power conversion module typically only outputs DC power. When used independently, an energy storage device 200 without a power conversion module can be used in conjunction with an energy storage device 200 with a power conversion module as a power system providing additional battery capacity.

[0055] In some embodiments, the energy storage device 200 further includes a circuit board. The circuit board is electrically connected to the battery cell 201. The circuit board may be a BMS (Battery Management System) board, a PSDR (Power Supply Driver) board, a board integrating BMS and PSDR functions, or a board with other functions.

[0056] Please see Figure 3 and Figure 4 In some embodiments, the housing module 100 includes a mounting housing 10 and a drain valve 20. The mounting housing 10 has a mounting space 101, and a drain hole 102 is provided at the bottom of the mounting housing 10, which communicates with the mounting space 101. The drain valve 20 is provided at the drain hole 102.

[0057] Please refer to the following: Figure 9 Specifically, the drain valve 20 includes a valve stem 21 and a valve core 22. The valve stem 21 is connected to the mounting housing 10. The valve core 22 is connected to the valve stem 21 and has a draining state with the drain hole 102 open and a sealing state with the drain hole 102 blocked. When the valve core 22 is in the sealing state, the edge of the valve core 22 abuts against the mounting housing 10 so that the valve core 22 and the mounting housing 10 form a closed space 220, and the drain hole 102 is located within the closed space 220. When the valve core 22 is in the draining state, the edge of the valve core 22 is separated from the mounting housing 10 so that the drain hole 102 communicates with the external environment.

[0058] Specifically, the battery cell 201 is disposed within the installation space 101.

[0059] By providing a drain hole 102 and a drain valve 20 at the bottom of the mounting housing 10, the drain valve 20 can open or close the drain hole 102, so that the condensate accumulated in the mounting space 101 can be discharged to the outside of the mounting housing 10 through the drain hole 102 when the drain valve 20 opens. This improves the problem of corrosion damage to the battery cell 201, power conversion module, circuit board and other internal components of the energy storage device caused by the accumulation of condensate in the mounting space 101, thereby extending the service life of the energy storage device 200.

[0060] Please see Figure 3 and Figure 4 In some embodiments, the valve core 22 is an umbrella-shaped structure, with the middle part of the umbrella-shaped structure connected to the valve stem 21. When the valve core 22 is in a sealed state, the edge of the umbrella-shaped structure abuts against the mounting housing 10. By setting the valve core 22 as an umbrella-shaped structure, due to the certain curvature of the umbrella-shaped structure, the contact between the valve core 22 and the mounting housing 10 will be tighter when the edge of the umbrella-shaped structure abuts against the mounting housing 10.

[0061] Specifically, the umbrella-shaped valve core 22 has an arc-shaped surface that protrudes in a direction away from the drain hole 102.

[0062] Please see Figure 3 and Figure 4 In some embodiments, the valve core 22 is located outside the mounting housing 10. The valve core 22 is an elastic structure and is configured to undergo elastic deformation under water pressure to separate from the mounting housing.

[0063] In some embodiments, the valve core 22 deforms under the gravity of the condensate to separate the edge of the valve core 22 from the mounting housing 10. By setting the valve core 22 as a flexible material, the valve core 22 can return to a sealed state after the condensate is discharged to the outside of the mounting space 101, thus realizing the automatic switching of the valve core 22 from the drainage state to the sealed state.

[0064] Optionally, the valve core 22 may be made of silicone or rubber.

[0065] Please see Figure 3 and Figure 4 In some embodiments, the valve stem 21 is provided with a limiting protrusion 210, and the mounting housing 10 is provided with a stop protrusion 14. After the valve stem 21 passes through the mounting housing 10, the limiting protrusion 210 and the stop protrusion 14 are matched to limit the valve stem 21 and the mounting housing 10 to fix the valve stem 21 to the mounting housing 10.

[0066] In the specific implementation process, when the valve core 22 is in a sealed state, the edge of the umbrella-shaped structure abuts against the mounting housing 10. The condensed water in the mounting space 101 flows into the closed space 220 formed by the valve core 22 and the mounting housing 10 and accumulates continuously until the condensed water in the closed space 220 accumulates to a predetermined weight. Then, the edge of the umbrella-shaped structure separates from the mounting housing 10 under the gravity of the condensed water to open the drain hole 102 and drain the water through the drain hole 102. After the water is drained to the outside of the mounting space 101, due to the disappearance of gravity, the elastic structure returns to the sealed state through its own elasticity. It can be seen that the above-mentioned setting of the valve core 22 can realize the automatic switching between the sealed state and the draining state of the valve core 22, and improve the timeliness of drainage of the housing module 100.

[0067] In some embodiments, when the condensation in the enclosed space 220 accumulates to a weight of 10g, the edge of the umbrella-shaped structure separates from the mounting housing 10 under the gravity of the condensation.

[0068] Please see Figure 3 and Figure 4 In some embodiments, the valve core 22 is provided with abutting ribs 221, which are disposed at the edge of the valve core 22 and abut against the mounting housing 10.

[0069] By providing abutting ribs 221 at the edge of the valve core 22 to form a structure protruding toward the mounting housing 10 at the edge of the valve core 22, when the abutting ribs 221 abut against the mounting housing 10, the valve core 22 and the mounting housing 10 can be in closer contact.

[0070] Specifically, the abutting ribs 221 are annular structures arranged with the center of the umbrella-shaped structure as the center, so as to seal various positions along the circumference of the umbrella-shaped structure, so that the valve core 22 has a good sealing effect.

[0071] Specifically, the abutting rib 221 has an abutting surface that contacts the mounting housing 10, and the abutting surface is an arc-shaped surface that protrudes toward the mounting housing 10.

[0072] Please see Figure 3 and Figure 4 In some embodiments, the valve core 22 is provided with a valve core reinforcing rib 222, which is located on the inner surface of the valve core 22 near the mounting housing 10. The valve core reinforcing rib 222 strengthens the structure of the valve core 22, thereby improving the problem that the valve core 22 is difficult to automatically return to its original shape when it is deformed.

[0073] In some embodiments, the valve core reinforcing rib 222 is an annular structure arranged with the center of the umbrella-shaped structure as the center. By setting the valve core reinforcing rib 222 as an annular structure, the structural strength of the valve core 22 is enhanced.

[0074] In some embodiments, the inner surface of the valve core 22 is located between the abutment rib 221 and the valve stem 21, and the minimum distance between the valve core reinforcing rib 222 and the abutment rib 221 is equal to the minimum distance between the valve core reinforcing rib 222 and the valve stem 21, so that the valve core reinforcing rib 222 is located at the middle position of the inner surface of the valve core 22.

[0075] In some embodiments, multiple valve core reinforcing ribs 222 are provided, and the multiple valve core reinforcing ribs 222 are spaced apart in a direction away from the valve stem 21. Specifically, the multiple valve core reinforcing ribs 222 are all annular structures, and the multiple annular valve core reinforcing ribs 222 are concentrically arranged.

[0076] Please see Figure 5 and Figure 6 In some embodiments, multiple drain holes 102 are provided, and the multiple drain holes 102 are arranged at intervals around the valve stem 21. The multiple drain holes 102 are all located on the side of the valve core 22 near the closed space 220.

[0077] By providing multiple drain holes 102, condensate in the installation space 101 can flow from various circumferential positions of the valve core 22 into the enclosed space 220 formed by the valve core 22 and the installation housing 10, thereby increasing the accumulation rate of condensate in the enclosed space 220 and thus improving drainage efficiency and reliability.

[0078] Please see Figure 5 and Figure 6 In some embodiments, the mounting housing 10 has a water storage tank 103, which is disposed at the bottom of the mounting housing 10. The water storage tank 103 has a bottom wall and a drain hole 102 is disposed at the bottom wall.

[0079] By providing a water storage tank 103 at the bottom of the mounting housing 10, and a drain hole 102 located on the bottom wall of the water storage tank 103, a height difference is formed between the bottom wall of the water storage tank 103 and the bottom wall of the mounting housing 10 located around the water storage tank 103, so that the condensed water can flow smoothly to the drain hole 102.

[0080] Please see Figure 5 and Figure 6 In some embodiments, the mounting housing 10 has a guide channel 110, which is disposed at the bottom of the mounting housing 10. The guide channel 110 surrounds the water storage tank 103 and communicates with the water storage tank 103, so as to guide the condensate in the mounting space 101 to the water storage tank 103 through the guide channel 110, so that the condensate flows smoothly to the drain hole 102.

[0081] In some embodiments, the guide channel 110 includes two first guide channel sections 111, which are arranged opposite to each other and are both connected to the water storage tank 103, so as to guide condensed water from two different directions toward the water storage tank 103 through the two first guide channel sections 111, thereby improving the guiding effect of condensed water.

[0082] Please see Figure 5 and Figure 6 In some embodiments, two drain valves 20 and two water storage tanks 103 are provided, with two drain valves 20 and two water storage tanks 103 arranged in a one-to-one correspondence. The distribution direction of the two water storage tanks 103 is perpendicular to the distribution direction of the two first guide channel sections 111, and each water storage tank 103 is located between the two first guide channel sections 111. By providing two water storage tanks 103, the amount of condensate collected can be increased.

[0083] Each first guide channel segment 111 includes a first channel segment 1111 and a second channel segment 1112. The first channel segment 1111 has a first guide surface, and the second channel segment 1112 has a second guide surface. The first guide surface and the second guide surface are respectively inclined toward the bottom wall of the two water storage tanks 103 so as to guide the condensed water into the two water storage tanks 103 respectively.

[0084] Please see Figure 5 and Figure 6 In some embodiments, the housing module 100 further includes a protective housing 30 disposed within the installation space 101. The protective housing 30 has a sealed chamber for accommodating the battery cell 201. The drain valve 20 and the protective housing 30 are spaced apart.

[0085] By placing the battery cell 201 within the sealed cavity of the protective housing 30, some water vapor can be blocked when it enters the installation space 101 of the mounting housing 10, reducing direct contact between water vapor and the battery cell 201. Combined with the drainage hole 102 and the drainage valve 20, when water accumulates to a certain level in the installation space 101, condensate is promptly drained through the drainage hole 102 and the drainage valve 20, thereby reducing the damage of condensate to other internal components of the energy storage device 200 and extending the service life of other internal components of the energy storage device 200.

[0086] Specifically, the sealed chamber of the protective housing 30 is provided with multiple mounting positions 31 for mounting multiple battery cell components of the battery cell 201.

[0087] Please see Figure 5 and Figure 6In some embodiments, the bottom of the mounting housing 10 is provided with two water-blocking ribs 11, the distribution direction of the two water-blocking ribs 11 is the same as the distribution direction of the two first guide channel sections 111, each water-blocking rib 11 is connected to the mounting housing 10 and extends to the water storage tank 103; the guide channel 110 includes a second guide channel section 112, the two water-blocking ribs 11 and the inner sidewall 13 of the mounting housing 10 form the second guide channel section 112, and the second guide channel section 112 is connected to the water storage tank 103.

[0088] Since the guide channel 110 is arranged around the water storage tank 103, there is a gap between the water storage tank 103 and the inner wall 13 of the mounting housing 10. By setting two water-blocking ribs 11 and dividing the guide channel 110 into a second guide channel section 112 and a first guide channel section 111, when the condensate is diverted in the first guide channel section 111, the condensate will not flow to the outside of the water storage tank 103 due to the obstruction and diversion of the water-blocking ribs 11. And the condensate in the remaining position of the installation space 101 is diverted into the water storage tank 103 through the second guide channel section 112, thereby improving the collection effect of condensate.

[0089] In some embodiments, both water-blocking ribs 11 are located on the same side of the water storage tank 103 away from the protective housing 30. The water storage tank 103 is located between the protective housing 30 and the two water-blocking ribs 11, and the two water-blocking ribs 11 and the protective housing 30 are respectively disposed at the edges of both sides of the water storage tank 103, so that the condensate on the outer surface of the protective housing 30 can flow directly into the water storage tank 103, and the condensate in the second guide channel section 112 can also flow directly into the water storage tank 103, thereby improving the collection effect of condensate.

[0090] Please see Figure 5 and Figure 6 In some embodiments, the housing module 100 further includes a housing reinforcing rib 12, which is disposed at the bottom of the second guide channel section 112. This reinforces the structural strength of the bottom of the housing by means of the housing reinforcing rib 12.

[0091] In some embodiments, the valve core 22 is located outside the mounting housing 10, and the housing module 100 includes a protective cover disposed outside the mounting housing 10 and covering the drain valve 20. The protective cover protects the valve core located on the outside, thereby mitigating the problem of wear on the drain valve 20. The protective cover has a communication opening that communicates with the outside, so that when the drain valve 20 opens the drain hole 102, condensate is discharged sequentially through the drain hole and the communication opening.

[0092] Please see Figure 4 , Figure 7 and Figure 8In some embodiments, the valve core 22 is located outside the mounting housing 10, and a receiving groove 104 is provided on the outside of the mounting housing 10. The valve core 22 is located in the receiving groove 104. By providing the receiving groove 104, the valve core 22 can be spaced apart from the support base surface, thereby improving the problem of wear caused by the contact between the drain valve 20 and the support base surface.

[0093] Optionally, the protective cover is disposed within the receiving groove 104 so that the protective cover is spaced apart from the supporting base surface, thereby improving the problem of wear caused by contact between the protective cover and the supporting base surface.

[0094] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
