[0130] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0131] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0132] The energy storage housing of an embodiment of the present invention is described below with reference to the accompanying drawings.
[0133] Combination Figures 1-6 As shown, the energy storage housing according to an embodiment of the present invention includes: an outer shell 100 and a separator 200.
[0134] Among them, combined Figure 2 and Figure 3 As shown, the housing 100 defines a receiving cavity 110. The housing 100 serves as a robust protective barrier for the entire energy storage housing, and its interior precisely defines the receiving cavity 110, providing a stable installation space for other components (such as the battery assembly 300, heat exchanger 400, etc.).
[0135] Combination Figure 2 and Figure 3As shown, the separator 200 is disposed within the receiving cavity 110 to divide the receiving cavity 110 into a first receiving cavity 111 and a second receiving cavity 112 that are independent of each other. This can be understood as follows: placing the separator 200 within the receiving cavity 110 facilitates the division of the receiving cavity 110 into a first receiving cavity 111 and a second receiving cavity 112 that are independent of each other, reduces the molding difficulty of the first receiving cavity 111 and the second receiving cavity 112, and can, to a certain extent, prevent interference between the structural components within the first receiving cavity 111 and the second receiving cavity 112.
[0136] Combination Figure 2 and Figure 3 As shown, the first receiving cavity 111 is suitable for installing the battery pack 300 and the heat exchanger 400, with the heat exchanger 400 exchanging heat with the battery pack 300. By exchanging heat with the battery pack 300, the heat exchanger 400 can be used to regulate the temperature of the battery pack 300 in real time, ensuring that the battery pack 300 is in optimal working condition and improving its performance to a certain extent.
[0137] It should be noted that the heat exchange between the battery module 300 and the heat exchanger 400 mentioned here means that when the temperature of the battery module 300 is high, the heat exchanger 400 is used to lower the temperature of the battery module 300; when the temperature of the battery module 300 is low, the heat exchanger 400 is used to raise the temperature of the battery module 300, thereby maintaining the temperature of the battery module 300 within a suitable temperature range during operation, ensuring that the battery module 300 is in its optimal working state, and improving the working performance of the battery module 300 to a certain extent.
[0138] Meanwhile, by installing the battery assembly 300 and the heat exchanger 400 into the first receiving cavity 111, it is also beneficial to use the housing 100 to support, fix and protect the battery assembly 300 and the heat exchanger 400, improve the positional stability of the battery assembly 300 and the heat exchanger 400, and extend the service life of the battery assembly 300 and the heat exchanger 400.
[0139] Combination Figure 2 and Figure 3 As shown, the second receiving cavity 112 is adapted to install a conveying member 500, which is used to convey a heat exchange medium toward the heat exchanger 400. By using the conveying member 500 to convey the heat exchange medium toward the heat exchanger 400, the temperature of the battery assembly 300 can be controlled in real time by the heat exchanger 400, reducing the difficulty of heat exchange between the heat exchanger 400 and the battery assembly 300, thereby improving the working performance of the battery assembly 300.
[0140] Meanwhile, by placing the conveyor 500 inside the second receiving cavity 112, the conveyor 500 is placed inside the outer casing 100, while the battery assembly 300 is placed inside the first receiving cavity 111. This allows the conveyor 500 and the battery assembly 300 to be independent of each other, thus avoiding the impact of condensation on the battery assembly 300 when the conveyor 500 condenses due to temperature differences. This further prevents short circuits in the battery assembly 300, thereby improving the safety of the battery assembly 300 and enhancing the working performance of the energy storage casing.
[0141] As can be seen from the above structure, the energy storage shell of this utility model embodiment, by setting a separator 200, divides the accommodating cavity 110 into a first accommodating cavity 111 and a second accommodating cavity 112 that are independent of each other, and places the conveying member 500 in the second accommodating cavity 112 and the battery assembly 300 in the first accommodating cavity 111, so that the conveying member 500 and the battery assembly 300 can be placed in different accommodating spaces, thereby making the conveying member 500 and the battery assembly 300 independent of each other, and to a certain extent avoiding the impact of condensate generated by the conveying member 500 on the battery assembly 300, thereby avoiding short circuit of the battery assembly 300 and improving the safety of the battery assembly 300.
[0142] It is understandable that, compared with the prior art, this application provides a separator 200 in the receiving cavity 110, and uses the separator 200 to separate the receiving cavity 110 into a first receiving cavity 111 and a second receiving cavity 112 that are independent of each other, so that the conveying component 500 and the battery assembly 300 can be respectively located in different receiving spaces, thereby making the conveying component 500 and the battery assembly 300 independent of each other, and to a certain extent avoiding the impact of condensate generated by the conveying component 500 on the battery assembly 300.
[0143] In some embodiments, the second receiving cavity 112 is provided with a drain outlet to facilitate the discharge of liquid in the second receiving cavity 112, thereby allowing the condensate generated by the conveying component 500 in the second receiving cavity 112 due to temperature difference to be discharged smoothly, which to a certain extent avoids the condensate from affecting the battery assembly 300, thereby preventing the battery assembly 300 from short-circuiting, improving the safety of the battery assembly 300, and thus improving the working performance of the energy storage casing.
[0144] In some embodiments, such as Figure 16As shown, the separator 200 is provided with a clearance hole 210, and at least a portion of the heat exchanger 400 passes through the clearance hole 210 and communicates with the conveyor 500, so that the connection position between the heat exchanger 400 and the conveyor 500 is located in the second receiving cavity 112. While enabling the heat exchanger 400 and the conveyor 500 to connect and cooperate, the connection point between the heat exchanger 400 and the conveyor 500 can also be located within the second receiving cavity 112. This makes the connection point between the heat exchanger 400 and the conveyor 500 independent of the battery assembly 300, thus avoiding leakage at the connection point and its impact on the battery assembly 300 to a certain extent. This further prevents short circuits in the battery assembly 300, thereby improving the safety of the battery assembly 300 and enhancing the performance of the energy storage housing. Furthermore, placing the connection point between the heat exchanger 400 and the conveyor 500 within the second receiving cavity 112 also avoids the connection point occupying space within the first receiving cavity 111, ensuring the capacity of the first receiving cavity 111. This reduces the installation difficulty of the battery assembly 300 and the heat exchanger 400, increases the capacity of the battery assembly 300, and ultimately improves the performance of the energy storage system 1000.
[0145] At the same time, by providing clearance holes 210, the assembly difficulty of at least part of the heat exchanger 400 can be reduced.
[0146] In some embodiments, the heat exchanger 400 includes a heat exchange body 410 and a first connecting pipe 420 that are in communication with each other. The heat exchange body 410 exchanges heat with the battery assembly 300, and the first connecting pipe 420 passes through the clearance hole 210 and connects to the conveyor 500. This allows at least a portion of the heat exchanger 400 to pass through the separator 200 and connect to the conveyor 500.
[0147] Meanwhile, by exchanging heat between the heat exchanger body 410 and the battery module 300, the heat exchange between the heat exchanger 400 and the battery module 300 is realized, reducing the difficulty of heat exchange between the heat exchanger 400 and the battery module 300. This makes it easier to use the heat exchanger 400 to regulate the temperature of the battery module 300 in real time, ensuring that the battery module 300 is in the best working state and improving the working performance of the battery module 300 to a certain extent.
[0148] In some embodiments, combined with Figure 17 and Figure 18As shown, the energy storage housing also includes a first sealing element 600, which is disposed in the clearance hole 210 and located between at least a portion of the heat exchanger 400 and the clearance hole 210. In other words, the first sealing element 600 is provided between at least a portion of the heat exchanger 400 and the clearance hole 210 to achieve a sealing fit between the at least portion of the heat exchanger 400 and the clearance hole 210. This enhances the sealing performance of the clearance hole 210 and also improves the connection strength between the at least portion of the heat exchanger 400 and the clearance hole 210.
[0149] By enhancing the sealing of the clearance hole 210, the first receiving cavity 111 and the second receiving cavity 112 can be made independent of each other, which to a certain extent avoids the impact of leakage at the connection between the heat exchanger 400 and the conveyor 500 on the battery assembly 300, avoids short circuit of the battery assembly 300, and thus improves the safety of the battery assembly 300.
[0150] Meanwhile, by increasing the connection strength between at least a portion of the heat exchanger 400 and the clearance hole 210, the positional stability of at least a portion of the heat exchanger 400 is improved, thereby ensuring the working performance of the heat exchanger 400 to a certain extent.
[0151] In some embodiments, combined with Figure 17 and Figure 18 As shown, the first sealing element 600 is disposed in the clearance hole 210 and located between the first connecting pipe 420 and the clearance hole 210, so as to achieve a sealing fit between the first connecting pipe 420 and the clearance hole 210.
[0152] In some embodiments, combined with Figure 17 and Figure 18 As shown, the first sealing element 600 can be a sealing ring. The sealing ring is sleeved on the outer periphery of the first connecting pipe 420 and is positioned directly opposite the clearance hole 210, so as to realize the first sealing element 600 being positioned between the first connecting pipe 420 and the clearance hole 210.
[0153] In some embodiments, the first seal 600 may be made of materials such as rubber or silicone to improve the sealing effect of the first seal 600.
[0154] In some embodiments, at least a portion of the heat exchanger 400 is fixedly connected to the clearance hole 210. This means that at least a portion of the heat exchanger 400 is fixedly engaged with the clearance hole 210 to improve the positional stability of at least a portion of the heat exchanger 400, thereby improving the working performance of the heat exchanger 400 and facilitating the connection and communication between the conveyor 500 and the heat exchanger 400.
[0155] In some embodiments, the first connecting pipe 420 is fixedly connected to the clearance hole 210 to fix at least a portion of the heat exchanger 400 to the clearance hole 210.
[0156] In some embodiments, combined with Figure 17 and Figure 18 As shown, the energy storage housing also includes a fastener 700, which is disposed at the clearance hole 210 and fixedly connected to at least a portion of the heat exchanger 400. This achieves fixed connection of at least a portion of the heat exchanger 400 to the clearance hole 210, reducing the difficulty of fixing at least a portion of the heat exchanger 400 to the clearance hole 210.
[0157] In some embodiments, a fastener 700 is disposed at the clearance hole 210 and fixedly connected to the first connecting pipe 420 to fix at least a portion of the heat exchanger 400 to the clearance hole 210.
[0158] In some embodiments, combined with Figure 17 and Figure 18 As shown, the fastener 700 is a fastening nut. The fastening nut is sleeved on the outer periphery of the first connecting pipe 420 and fixedly connected to the first connecting pipe 420. The outer periphery of the fastening nut is engaged with the partition 200 with the clearance hole 210, thereby realizing the use of the fastener 700 to fix the first connecting pipe 420 to the clearance hole 210, reducing the difficulty of fixing the first connecting pipe 420 and the clearance hole 210.
[0159] In some embodiments, combined with Figure 17 and Figure 18 As shown, the outer periphery of the first connecting pipe 420 is provided with external threads, and the inner periphery of the fastening nut is provided with internal threads. The first connecting pipe 420 and the fastener 700 are fixedly connected through the cooperation of the internal and external threads.
[0160] In some embodiments, combined with Figure 17 and Figure 18 As shown, the energy storage housing also includes a washer 610, which is located between the fastening nut and the partition 200 with the clearance hole 210. This is to a certain extent to prevent damage to the partition 200 after the fastening nut is tightened, and to extend the service life of the partition 200.
[0161] In some embodiments, the first connecting pipe 420 is welded to the heat exchange body 410. This increases the connection strength between the first connecting pipe 420 and the heat exchange body 410, prevents leakage at the connection point, and thus avoids affecting the battery assembly 300, thereby improving the safety of the battery assembly 300.
[0162] Of course, in other embodiments, the connection between the first connecting pipe 420 and the heat exchange body 410 can also be by bonding or other connection methods, as long as leakage at the connection position between the first connecting pipe 420 and the heat exchange body 410 can be avoided. This application does not impose any restrictions here.
[0163] In some embodiments, the partition 200 is connected to the housing 100, and a second sealing member 900 is provided between the partition 200 and the housing 100 (the specific structure of the second sealing member 900 can be found in [reference]). Figure 42 When the separator 200 is connected to the housing 100, the housing 100 can support the separator 200, improving the positional stability of the separator 200 and ensuring its working performance to a certain extent.
[0164] Meanwhile, by providing a second sealing element 900 between the separator 200 and the outer shell 100, a sealing fit is achieved between the separator 200 and the outer shell 100, thereby making the first receiving cavity 111 and the second receiving cavity 112 relatively sealed. This avoids leakage at the connection between the heat exchanger 400 and the conveying element 500 from affecting the battery assembly 300, thereby preventing short circuits in the battery assembly 300 and improving the safety of the battery assembly 300.
[0165] In some embodiments, the second seal 900 may be a sealing strip or a sealing ring, etc.
[0166] In some embodiments, the separator 200 is fixedly connected to the housing 100 to achieve a mating connection between the separator 200 and the housing 100.
[0167] The fixed connection mentioned here can be a non-removable connection (such as welding, bonding, etc.) or a removable connection (such as snap-fit, bolt connection, or stop fit, etc.).
[0168] In some embodiments, combined with Figure 1 , Figure 2 and Figure 3 As shown, the outer casing 100 has a first side plate 120 and a second side plate 130 disposed opposite each other in a first direction, a third side plate 140 and a fourth side plate 150 disposed opposite each other in a second direction, and a fifth side plate 160 and a sixth side plate 170 disposed opposite each other in a third direction. The first side plate 120, the second side plate 130, the third side plate 140, the fourth side plate 150, the fifth side plate 160, and the sixth side plate 170 cooperate to form a receiving cavity 110. The first direction, the second direction, and the third direction intersect each other in pairs. Here, the first direction can be understood as... Figure 3 The Y direction shown, the second direction can be understood as Figure 3 The X direction shown can be understood as the third direction. Figure 3 As shown in the Z direction, the molding strength of the receiving cavity 110 can be reduced by the above-mentioned arrangement, thereby facilitating the placement of some structural components (battery assembly 300, heat exchange component 400, and conveying component 500, etc.) inside the outer casing 100.
[0169] In a specific embodiment, the Y direction is formed as the front-to-back direction of the energy storage housing, the X direction is formed as the left-to-right direction of the energy storage housing, and the Z direction is formed as the up-to-down direction of the energy storage housing. This makes the first side plate 120 form the front door assembly of the energy storage housing, the second side plate 130 form the rear door assembly of the energy storage housing, the third side plate 140 form the left side plate assembly of the energy storage housing, the fourth side plate 150 form the right side plate assembly of the energy storage housing, the fifth side plate 160 form the top assembly of the energy storage housing, and the sixth side plate 170 form the base assembly of the energy storage housing.
[0170] In some embodiments, the first side plate 120, the second side plate 130, the third side plate 140, the fourth side plate 150, the fifth side plate 160, and the sixth side plate 170 are detachably connected. This reduces the difficulty of molding the housing 100 and also facilitates the production, assembly, and subsequent maintenance of the housing 100.
[0171] It should be noted that the detachable connection mentioned above can be a snap-fit connection, a bolt connection, etc.
[0172] In a specific example, the first side plate 120 and the second side plate 130 are detachably connected to the third side plate 140, the fourth side plate 150, the fifth side plate 160 and the sixth side plate 170, respectively. The third side plate 140 and the fourth side plate 150 are detachably connected to the first side plate 120, the second side plate 130, the fifth side plate 160 and the sixth side plate 170, respectively. The fifth side plate 160 and the sixth side plate 170 are detachably connected to the first side plate 120, the second side plate 130, the third side plate 140 and the fourth side plate 150, respectively, so as to realize the detachable connection between the first side plate 120, the second side plate 130, the third side plate 140, the fourth side plate 150, the fifth side plate 160 and the sixth side plate 170.
[0173] In some embodiments, through the detachable connection described above, when there are multiple sets of battery components 300, the housing 100 can be assembled after the multiple sets of battery components 300 are assembled, which reduces the assembly difficulty of the energy storage system 1000 and helps to improve the automation level of the energy storage system 1000 in the assembly process.
[0174] In some embodiments, a third seal 127 is provided at the mating connection of the first side plate 120, the second side plate 130, the third side plate 140, the fourth side plate 150, the fifth side plate 160, and the sixth side plate 170 (the specific structure of the third seal 127 can be found in [reference]). Figure 34 This achieves a sealing fit between the first side plate 120, the second side plate 130, the third side plate 140, the fourth side plate 150, the fifth side plate 160, and the sixth side plate 170, thereby ensuring the sealing performance of the receiving cavity 110.
[0175] In some embodiments, the third seal 127 may be a sealing strip or a sealing ring, etc.
[0176] In some embodiments, combined with Figure 1 , Figure 2 and Figure 3 As shown, at least one reinforcing beam 180 is provided on the first side plate 120, the second side plate 130, the third side plate 140, the fourth side plate 150, the fifth side plate 160 and / or the sixth side plate 170. The reinforcing beam 180 is used to strengthen the structural strength and protective performance of the outer shell 100 and improve the ability of the outer shell 100 to resist external impact.
[0177] In some embodiments, combined with Figure 1 , Figure 2 and Figure 3 As shown, the first side plate 120, the second side plate 130, the third side plate 140, the fourth side plate 150, the fifth side plate 160 and / or the sixth side plate 170 are provided with heat insulation members 190 on the side facing the receiving cavity 110. This can reduce heat loss and maintain a constant temperature environment inside the receiving cavity 110, which is beneficial to improving the working performance of the battery assembly 300.
[0178] In some embodiments, the insulation component 190 is insulation cotton or heat insulation board, etc.
[0179] In some embodiments, combined with Figure 1 , Figure 2 and Figure 5 As shown, a switch door 121 is provided on one of the first side plate 120 and the second side plate 130. The switch door 121 is used to open or close the receiving cavity 110. This facilitates the inspection, replacement and other operations of the internal components of the receiving cavity 110.
[0180] In specific examples, combined Figure 2 and Figure 27 As shown, a switch door 121 is provided on the first side panel 120.
[0181] In some embodiments, combined with Figure 27 , Figure 28 , Figure 29 and Figure 30As shown, the first side panel 120 forms a front door assembly, which is composed of a first horizontal beam 122, a first vertical beam 123, two reinforcing beams 180, a second vertical beam 124, a second horizontal beam 125, a wire sealing plate 126, a first door 1211, a second door 1212, a third door 1213, and a fourth sealing element 129. The first horizontal beam 122, the first vertical beam 123, the two reinforcing beams 180, the second vertical beam 124, and the second horizontal beam 125 are square tubing welded into a frame. Hinges are installed at corresponding locations to connect the first door 1211 and the second door 1212. The three door panels 212 and the third switch door 1213 are assembled on the corresponding hinges. The thermal insulation component 190 is attached to the first switch door 1211, the second switch door 1212 and the third switch door 1213. A fourth sealing component 129 is set on the overall frame to realize the fourth sealing component 129 between the first switch door 1211, the second switch door 1212 and the third switch door 1213 and the overall frame. Finally, fastening bolts 128 are pre-installed on the first crossbeam 122, the first vertical beam 123, the second vertical beam 124 and the second crossbeam 125 of the overall frame to form the front door assembly.
[0182] Among them, the front door assembly can buffer and block some of the impact forces received by the outside of the energy storage shell, and further ensure the working performance of the internal components of the energy storage shell to a certain extent.
[0183] It should be noted that, as Figure 27 As shown, by setting the switch doors 121 as a first switch door 1211, a second switch door 1212, and a third switch door 1213 respectively, the first switch door 1211, the second switch door 1212, and the third switch door 1213 can be opened respectively, so that the internal components of the energy storage shell corresponding to the first switch door 1211, the second switch door 1212, and the third switch door 1213 can be replaced in a timely manner, which to a certain extent ensures the working performance of the internal components of the energy storage shell, thereby ensuring the working performance of the energy storage system 1000.
[0184] Meanwhile, by pre-installing fastening bolts 128 on the first horizontal beam 122, the first vertical beam 123, the second vertical beam 124, and the second horizontal beam 125 of the overall frame, the assembly difficulty of the first horizontal beam 122, the first vertical beam 123, the second vertical beam 124, and the second horizontal beam 125 can be reduced, thereby achieving a detachable connection of the first horizontal beam 122, the first vertical beam 123, the second vertical beam 124, and the second horizontal beam 125.
[0185] In some embodiments, combined with Figure 31 , Figure 32 , Figure 33 and Figure 34As shown, the second side panel 130 is formed as a rear door assembly, which is composed of a third crossbeam 131, a fourth crossbeam 132, a third vertical beam 133, a fourth vertical beam 134, two reinforcing beams 180, a first sheet metal cover 135, a second sheet metal cover 136, a third sheet metal cover 137, a thermal insulation component 190, and a third sealing component 127. The third crossbeam 131, the fourth crossbeam 132, the third vertical beam 133, the fourth vertical beam 134, and the sheet metal covers (the first sheet metal cover 135, the second sheet metal cover 136, and the third sheet metal cover 137) are welded together. The thermal insulation component 190 fills the side of the sheet metal cover facing the receiving cavity 110 to form the rear door assembly.
[0186] The rear door assembly can buffer and block some of the impact forces received by the energy storage system 1000 from the outside, thereby ensuring the working performance of the internal components of the energy storage system 1000 to a certain extent.
[0187] In some embodiments, combined with Figure 32 , Figure 33 and Figure 34 As shown, the rear door assembly also includes fastening screws 138, which are used to fix the insulation component 190 and the first sheet metal cover 135, the insulation component 190 and the second sheet metal cover 136, and the insulation component 190 and the third sheet metal cover 137, respectively. The fastening screws 138 can, to a certain extent, prevent the insulation component 190 from shifting, thereby ensuring the structural stability of the insulation component 190 and thus guaranteeing its insulation effect.
[0188] In the specific example, the fastening screw 138 is a nylon screw. Nylon screws are lightweight, corrosion-resistant, insulating, and wear-resistant. Compared to other screws, nylon screws are lightweight yet durable and can be well used to secure the insulation component 190.
[0189] In some embodiments, combined with Figure 32 , Figure 33 and Figure 34 As shown, the rear door assembly also includes a fastening bolt 128, which facilitates the securing of the rear door assembly.
[0190] In some embodiments, combined with Figure 35 , Figure 36 and Figure 37As shown, the third side panel 140 is formed as a left side panel assembly, and the fourth side panel 150 is formed as a right side panel assembly. Both the left and right side panel assemblies are welded together from a top beam 141, a fifth vertical beam 142, a sixth vertical beam 143, a reinforcing beam 180, a bottom beam 144, a fourth sheet metal cover 145, and a fifth sheet metal cover 146. The insulation component 190 is filled into the side of the fourth sheet metal cover 145 and the fifth sheet metal cover 146 facing the receiving cavity 110 to form the left and right side panel assemblies.
[0191] The left and right side panels can buffer and block some of the impact forces on the energy storage system 1000 from the outside, and further ensure the working performance of the internal components of the energy storage system 1000 to a certain extent.
[0192] In some embodiments, combined with Figure 35 , Figure 36 and Figure 37 As shown, the left and right side plate assemblies also include a top lifting block 147 and a bottom lifting block 148. The top lifting block 147 is welded to the top beam 141, and the bottom lifting block 148 is welded to the bottom beam 144, so as to facilitate the transport of the energy storage shell using the top lifting block 147 and the bottom lifting block 148.
[0193] In some embodiments, combined with Figures 38-42 As shown, the partition 200 is welded together from the left sheet metal 220, the middle sheet metal 230, the right sheet metal 240, the junction box 250, the second sealing element 900, the locking bolt 260, the smoke detector mounting base 270, the smoke detector mounting base cover plate 280, and the aerosol mounting base 290 to form an integral partition 200. By setting the partition 200, the first receiving cavity 111 and the second receiving cavity 112, which are independent of each other, can be separated within the receiving cavity 110.
[0194] In some embodiments, the separator 200 is provided with at least one of a junction box 250, a smoke detector mounting base 270, and an aerosol mounting base 290. This refers to the fact that the separator 200 can be equipped with one or more of the following: a junction box 250, a smoke detector mounting base 270, and an aerosol mounting base 290. The junction box 250 facilitates the electrical connection between the battery assembly 300 and an external power source, reducing the difficulty of electrical connection. The smoke detector mounting base 270 provides a stable mounting foundation for the smoke detector, ensuring that it will not shift or fall due to vibration or shaking during the operation of the energy storage system 1000, thus ensuring the normal operation of the smoke detector and the safety of the energy storage system 1000. The smoke detector mounting base cover 280 provides physical protection for the smoke detector, preventing it from being affected by external environmental factors such as dust, moisture, and corrosive gases, thereby extending the service life of the smoke detector and ensuring the stability of its performance.
[0195] In addition, by setting up the aerosol mounting base 290, the aerosol fire extinguishing device can be firmly fixed in place, so that it will not be displaced or fall off due to vibration or shaking, thus ensuring that the aerosol fire extinguishing device can play its role accurately when needed, since the energy storage system 1000 may vibrate during operation.
[0196] It should also be noted that the locking bolt 260 is used to fix the left sheet metal 220, the middle sheet metal 230, the right sheet metal 240, the second sealing element 900 and the insulation element 190, so as to ensure the structural stability of the partition 200.
[0197] In some embodiments, combined with Figure 43 , Figure 44 , Figure 45 and Figure 46 As shown, the fifth side plate 160 forms the top assembly, which is composed of the fifth crossbeam 161, the sixth crossbeam 162, the seventh crossbeam 163, the insulation component 190, the third sealing component 127, the explosion relief plate 164, the left longitudinal beam 165, the middle longitudinal beam 166, and the right longitudinal beam 167. The top assembly can both support the liquid supply component 800 and buffer and block some of the impact forces received by the energy storage system 1000 from the outside, thereby ensuring the working performance of the internal components of the energy storage system 1000 to a certain extent.
[0198] By setting up a pressure relief plate 164, when the pressure inside the energy storage system 1000 rises sharply due to reasons such as thermal runaway of the battery component 300, the pressure relief plate 164 will open when the pressure reaches a preset threshold, so that the inside of the energy storage system 1000 is connected to the outside, and the excess pressure and gas are released in an orderly manner, so as to prevent the energy storage system 1000 from exploding or being seriously damaged due to excessive internal pressure, thereby ensuring the safety of the energy storage system 1000.
[0199] In some embodiments, combined with Figure 43 , Figure 44 , Figure 45 and Figure 46 As shown, the top assembly also includes a top corrugated plate 168 to increase the structural strength of the top assembly.
[0200] In some embodiments, combined with Figures 47-52 As shown, the sixth side plate 170 forms a base assembly, which is welded together from the eighth crossbeam 171, the ninth crossbeam 172, four reinforcing beams 180, insulation component 190, first longitudinal beam 173, second longitudinal beam 174, bottom connecting block 175, and sheet metal component 176. The base assembly can both support the battery assembly 300 and buffer and block some of the impact forces received by the energy storage system 1000 from the outside, thereby ensuring the working performance of the internal components of the energy storage system 1000 to a certain extent.
[0201] In some embodiments, the bottom connecting block 175 is provided with a female threaded interface. When the energy storage system 1000 is maintained, repaired, or the base assembly needs to be replaced, the bottom connecting block 175 with the female threaded interface makes the disassembly and installation process more convenient. The staff can easily unscrew the bolts and separate or replace the relevant parts, thereby improving the maintenance efficiency of the base assembly.
[0202] In the description of this utility model, the features defined as "first", "second", "third", "fourth", "fifth", "sixth", "seventh", "eighth" and "ninth" may explicitly or implicitly include one or more of the features, used to distinguish the descriptive features, without any order or importance.
[0203] In some embodiments, a grounding component (not shown) is also welded onto the base assembly to improve the safety of the energy storage housing. When an electrical fault occurs in the energy storage system 1000, such as leakage or short circuit, the grounding component can quickly conduct the fault current to the ground, preventing electric shock to personnel and damage to equipment, and ensuring the electrical safety of the energy storage system 1000.
[0204] The energy storage system 1000 of this utility model is described below with accompanying drawings.
[0205] Combination Figures 1-6As shown, the energy storage system 1000 according to an embodiment of the present invention includes: an energy storage shell, a battery assembly 300, a heat exchange component 400, and a conveying component 500.
[0206] The energy storage housing is the aforementioned energy storage housing. The specific structure of the energy storage housing will not be described in detail here. The battery assembly 300 and the heat exchanger 400 are located in the first receiving cavity 111, and the conveying component 500 is located in the second receiving cavity 112.
[0207] The energy storage system 1000 according to the present utility model, by adopting the aforementioned energy storage shell, is beneficial to improving the safety of use of the energy storage system 1000 and extending the service life of the energy storage system 1000.
[0208] It should be noted that the energy storage system 1000 here can be understood as a battery cabinet or battery pack, etc.
[0209] In some embodiments, the heat exchanger 400 is made of a material resistant to high salt spray, which makes the heat exchanger 400 suitable for more demanding application conditions, thereby enabling the heat exchanger 400 to adapt to high-altitude applications above 5000 meters, and thus expanding the application range of the energy storage system 1000.
[0210] In some embodiments, the heat exchanger 400 has a liquid inlet and a liquid outlet, both of which pass through the separator 200 and communicate with the conveyor 500 to facilitate the circulation of the heat exchange medium. This allows for easy adjustment of the temperature of the heat exchange medium, maintaining it within a suitable temperature range, thereby facilitating the adjustment of the temperature of the battery assembly 300 using the heat exchange medium and improving the operating performance of the heat exchanger 400.
[0211] In some embodiments, combined with Figure 19 and Figure 20 As shown, the conveying component 500 includes a first conveying component 510 and a second conveying component 520. The liquid inlet is connected to the first conveying component 510, and the liquid outlet is connected to the second conveying component 520. This enables the conveying component 500 and the heat exchanger 400 to be connected, facilitating the delivery of the heat exchange medium from the conveying component 500 to the heat exchanger 400. This allows the heat exchanger 400 to control the temperature of the battery assembly 300 in real time, reducing the difficulty of heat exchange between the heat exchanger 400 and the battery assembly 300, thereby improving the performance of the battery assembly 300.
[0212] In addition, the above settings facilitate the circulation of the heat exchange medium.
[0213] In a specific example, the first conveyor 510 is used to convey the heat exchange medium toward the inlet, and the second conveyor 520 is used to receive the heat exchange medium discharged from the outlet, thereby realizing the circulation of the heat exchange medium.
[0214] In some embodiments, combined with Figure 19 and Figure 20 As shown, the energy storage system 1000 also includes a liquid supply unit 800, which is connected to the first conveying unit 510 and the second conveying unit 520 respectively. The liquid supply unit 800 is used to supply heat exchange medium to the first conveying unit 510 and receive heat exchange medium in the second conveying unit 520, so as to control the circulation flow of the heat exchange medium and reduce the difficulty of the circulation flow of the heat exchange medium.
[0215] In some embodiments, the liquid supply element 800 exchanges heat with the heat exchange medium. This allows for the adjustment of the temperature of the heat exchange medium using the liquid supply element 800, thereby facilitating the adjustment of the temperature of the heat exchange medium within a suitable temperature range. This, in turn, facilitates the adjustment of the temperature of the battery assembly 300 using the heat exchange medium, improving the operating performance of the heat exchange element 400.
[0216] In some embodiments, the liquid supply unit 800 is a liquid-cooled air conditioner, which precisely controls the temperature of the battery module 300 by circulating heat exchange medium, thereby ensuring the stability and safety of the energy storage system 1000.
[0217] In some embodiments, such as Figure 20 As shown, the liquid-cooled air conditioner is located on top of the energy storage shell, which can effectively utilize space and avoid the problem of insufficient air circulation volume of the liquid-cooled air conditioner, thereby improving the working performance of the liquid-cooled air conditioner.
[0218] In some embodiments, combined with Figure 19 and Figure 20 As shown, the conveying component 500 also includes a first adapter 530 and a second adapter 540. The opposite ends of the first adapter 530 are respectively connected to the liquid supply component 800 and the first conveying component 510, and the end of the first adapter 530 connected to the first conveying component 510 is positioned near the middle of the extending direction of the first conveying component 510. By connecting the opposite ends of the first adapter 530 to the liquid supply component 800 and the first conveying component 510, the connection between the liquid supply component 800 and the first conveying component 510 is achieved, reducing the difficulty of connecting them. This facilitates the delivery of the heat exchange medium from the liquid supply component 800 to the first conveying component 510, thereby achieving the purpose of delivering the heat exchange medium to the heat exchanger 400 and improving the working performance of the heat exchanger 400.
[0219] Meanwhile, by setting one end of the first adapter 530 connected to the first conveyor 510 close to the middle of the extension direction of the first conveyor 510, the flow rate of the heat exchange medium entering the first conveyor 510 is ensured to be uniform, thereby achieving the purpose of temperature consistency.
[0220] In some embodiments, combined with Figure 19 and Figure 20As shown, the two opposite ends of the second adapter 540 are respectively connected to the liquid supply component 800 and the second conveying component 520, and the end of the second adapter 540 connected to the second conveying component 520 is located near the middle of the extending direction of the second conveying component 520. By connecting the two opposite ends of the second adapter 540 to the liquid supply component 800 and the second conveying component 520, the connection between the liquid supply component 800 and the second conveying component 520 is achieved, reducing the difficulty of connecting the liquid supply component 800 and the second conveying component 520. This facilitates the delivery of the heat exchange medium in the second conveying component 520 to the liquid supply component 800, thereby achieving the circulation of the heat exchange medium.
[0221] Meanwhile, by setting one end of the second adapter 540 connected to the second conveyor 520 close to the middle of the extension direction of the second conveyor 520, the flow distribution of the heat exchange medium discharged through the second conveyor 520 is ensured to be uniform, thereby achieving the purpose of temperature uniformity.
[0222] In some embodiments, combined with Figure 19 and Figure 20 As shown, the first adapter 530 and the second adapter 540 are respectively installed in the outer casing 100 and connected to the liquid supply unit 800.
[0223] In some embodiments, combined with Figure 19 and Figure 20 As shown, the conveying component 500 also includes multiple second connecting pipes 550, which are respectively connected to the first conveying component 510 and the liquid inlet, and to the second conveying component 520 and the liquid outlet. This means that when multiple second connecting pipes 550 are provided, a portion of the second connecting pipes 550 are connected to the first conveying component 510 and the liquid inlet, while another portion of the second connecting pipes 550 are connected to the second conveying component 520 and the liquid outlet, thereby achieving cooperative communication between the conveying component 500 and the heat exchanger 400.
[0224] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0225] In some embodiments, the second connecting pipe 550 is a flexible pipe, and the first conveying member 510 and the second conveying member 520 are rigid members. By forming the conveying member 500 in a configuration where a flexible member and a rigid member are connected, the product reliability of the conveying member 500 can be improved, ensuring reliable sealing under high-frequency vibration conditions and enhancing the working performance of the conveying member 500 to a certain extent.
[0226] Meanwhile, by setting the second connecting pipe 550 as a flexible pipe, the second connecting pipe 550 can release stress and improve the sealing problem caused by the tolerance of rigid connection; by setting the first conveying member 510 and the second conveying member 520 as rigid members, it is beneficial to improve the structural stability of the first conveying member 510 and the second conveying member 520 and extend the service life of the first conveying member 510 and the second conveying member 520.
[0227] In some embodiments, the second connecting tube 550 is a plastic tube or silicone tube with high insulation performance. While making the second connecting tube 550 a flexible tube, it also helps to achieve high insulation between the battery module 300 and the second connecting tube 550, prevents arcing discharge of the battery module 300, and ensures the safety of the battery module 300 in use.
[0228] In some embodiments, the insulating hose meets a 35KV high voltage requirement.
[0229] In some embodiments, the first conveying member 510 and the second conveying member 520 are steel pipes, aluminum pipes, etc., so that the first conveying member 510 and the second conveying member 520 are formed as rigid members.
[0230] In some embodiments, the first adapter 530 and the second adapter 540 are formed as flexible tubes. This ensures that the first adapter 530 and the second adapter 540 maintain reliable sealing under high-frequency vibration conditions, thereby improving the working performance of the conveyor 500 to a certain extent.
[0231] In some embodiments, the first adapter 530 and the second adapter 540 may be plastic tubing or silicone tubing, such that the first adapter 530 and the second adapter 540 are formed as flexible tubes.
[0232] In some embodiments, the first conveying member 510 and the second conveying member 520 are locked within the second receiving cavity 112 by pipe clamps. This not only reduces the difficulty of fixing the first conveying member 510 and the second conveying member 520, but also improves the positional stability of the first conveying member 510 and the second conveying member 520, ensuring the working performance of the first conveying member 510 and the second conveying member 520.
[0233] In some embodiments, such as Figure 19 As shown, an exhaust valve 560 is provided on the conveyor 500, and the exhaust valve 560 is located near the top of the conveyor 500. The exhaust valve 560 is used to discharge the gas inside the conveyor 500, so as to prevent air resistance from being generated inside the conveyor 500, thus avoiding energy loss and improving the performance of the conveyor 500.
[0234] In some embodiments, such as Figure 19As shown, the exhaust valve 560 is connected to the first conveyor 510 and the second conveyor 520. In this way, the exhaust valve 560 can also be used to discharge the gas in the first conveyor 510 and the second conveyor 520, which can prevent the generation of air resistance in the first conveyor 510 and the second conveyor 520 and the loss of energy to a certain extent.
[0235] In some embodiments, such as Figure 19 As shown, the conveying member 500 also includes a drain pipe 570, which connects to the first conveying member 510 and the second conveying member 520 respectively and is located at the bottom of the first conveying member 510 and the second conveying member 520. This is to facilitate the discharge of residual heat exchange medium inside the conveying member 500 using the drain pipe 570, thereby enabling the conveying member 500 to receive heat exchange medium being conveyed toward it.
[0236] In some embodiments, combined with Figure 22 and Figure 23 As shown, the battery assembly 300 includes a plurality of battery cells 310 arranged along a first direction, and the heat exchanger 400 extends along the first direction. Here, the first direction can be understood as... Figure 22 As shown in the Y direction, by aligning the arrangement direction of multiple battery cells 310 with the extension direction of the heat exchanger 400, it is beneficial to use the same heat exchanger 400 to exchange heat with multiple battery cells 310 simultaneously, thereby achieving uniform heat dissipation for multiple battery cells 310, reducing the temperature difference between multiple battery cells 310, and preventing the discharge capacity of the entire battery assembly 300 from decreasing due to the rapid aging of one battery cell 310. This can extend the lifespan of the battery assembly 300 and ensure its capacity.
[0237] Meanwhile, by configuring the battery module 300 to include multiple battery cells 310, it is beneficial to increase the capacity of the battery module 300, thereby improving the working performance of the battery module 300.
[0238] In some embodiments, combined with Figure 11 , Figure 17 and Figure 22 As shown, in the second direction, the heat exchanger 400 has a first heat exchange channel 430 and a second heat exchange channel 440. One end of the first heat exchange channel 430 and the second heat exchange channel 440 are connected to each other in the first direction, and the other end of the first heat exchange channel 430 and the second heat exchange channel 440 are connected to the conveying member 500. One of the first heat exchange channel 430 and the second heat exchange channel 440 forms a liquid inlet channel, and the other forms a liquid outlet channel. The liquid inlet is connected to the liquid inlet channel, and the liquid outlet is connected to the liquid outlet channel. The second direction intersects with the first direction. Here, the second direction can be understood as... Figure 11 and Figure 17In the X direction shown, by configuring the heat exchanger 400 with a first heat exchange channel 430 and a second heat exchange channel 440 to facilitate the circulation of the heat exchange medium, and by connecting the first heat exchange channel 430 to the liquid inlet to receive the heat exchange medium from the first conveyor 510, and connecting the second heat exchange channel 440 to the liquid outlet to discharge the heat exchange medium to the second conveyor 520, the temperature of the battery assembly 300 can be better adjusted, thereby keeping the battery assembly 300 within a suitable operating temperature range.
[0239] In some embodiments, such as Figure 11 As shown, there are two first heat exchange channels 430 and one second heat exchange channel 440. The two first heat exchange channels 430 are located on opposite sides of the second heat exchange channel 440 in the second direction. The two first heat exchange channels 430 and one second heat exchange channel 440 work together to adjust the temperature of the battery assembly 300, which helps to reduce the temperature difference between multiple locations of the battery assembly 300, thereby enabling the battery assembly 300 to be maintained within a suitable operating temperature range.
[0240] In a specific example, the above settings can promote a temperature difference of ≤2℃ for the uniform temperature of the battery assembly 300.
[0241] In some embodiments, the first heat exchange channel 430 forms a liquid inlet channel, and the second heat exchange channel 440 forms a liquid outlet channel.
[0242] Of course, in some other embodiments, the first heat exchange channel 430 may also form a liquid outlet channel and the second heat exchange channel 440 may form a liquid inlet channel.
[0243] In some embodiments, combined with Figure 24 , Figure 25 and Figure 26 As shown, the battery assembly 300 includes multiple groups of battery assemblies 300 arranged along a third direction. The heat exchanger 400 includes a first heat exchanger 450 and a second heat exchanger 460. The first heat exchanger 450 is disposed between two adjacent groups of battery assemblies 300. The multiple groups of battery assemblies 300 are respectively provided with second heat exchangers 460 at opposite ends of the third direction. The third direction intersects the first direction and the second direction in pairs. Here, the third direction can be understood as... Figure 25 and Figure 26 As shown in the Z direction, by configuring the battery assembly 300 to include multiple groups, it is beneficial to improve the energy storage effect of the energy storage system 1000, thereby improving the working performance of the energy storage system 1000.
[0244] Meanwhile, by configuring the heat exchanger 400 to include a first heat exchanger 450 and a second heat exchanger 460, and placing the first heat exchanger 450 between two adjacent battery modules 300, and providing the second heat exchanger 460 at opposite ends of multiple battery modules 300 in the third direction, each battery cell 310 is provided with a heat exchanger 400 on opposite sides in the third direction. This ensures that each battery module 300 can effectively and evenly contact the heat exchanger 400, avoiding uneven heat dissipation caused by some battery modules 300 not contacting the heat exchanger 400 due to assembly tolerances. This increases the heat dissipation area of multiple battery modules 300, allowing multiple battery modules 300 to be maintained within a suitable operating temperature range, which is beneficial to improving the working performance of the battery modules 300.
[0245] In a specific example, with the above configuration, the heat exchanger 400 and the battery assembly 300 can form a sandwich structure, with the battery assembly 300 sandwiched between the two layers of heat exchanger 400, ensuring that both contact surfaces of the battery assembly 300 in the Z direction can contact the heat exchanger 400, thereby increasing the heat dissipation area of the battery assembly 300.
[0246] In some embodiments, the energy storage system 1000 further includes a heat-conducting element (not shown) disposed between the battery module 300 and the heat exchanger 400. The heat-conducting element can enhance the heat transfer efficiency between the battery module 300 and the heat exchanger 400, and also fill the contact gaps between them, thereby ensuring that heat can be transferred between the battery module 300 and the heat exchanger 400 at the fastest speed, improving the overall thermal management performance of the battery module 300.
[0247] In some embodiments, the thermally conductive component is a thermally conductive adhesive, which is filled between the battery assembly 300 and the heat exchanger 400.
[0248] In some embodiments, multiple battery modules 300 are arranged side-by-side or back-to-back to improve the space utilization of the energy storage system 1000.
