Description

Technical Field

[0001] This application relates generally to the technical field of container structures, and more specifically to a battery rack and energy storage container. Background Technology

[0002] With the development of the energy storage industry, energy storage containers, as an emerging energy storage solution, are constantly advancing in technology. Energy storage containers typically house battery packs, such as lithium-ion battery packs, to efficiently store large amounts of electrical energy, while battery racks are responsible for the installation and securing of these battery packs. The design of the battery racks must meet both strength requirements and assembly efficiency.

[0003] In the process of assembling battery packs and other battery units, related technologies require pushing the battery units to the battery rack assembly position and securing them with fasteners to ensure stability. However, these technologies suffer from insufficient positioning accuracy, which can easily lead to battery unit positional deviations, such as being too far back, too far forward, too far to the left, or too far to the right. This results in the battery units not being able to accurately align with the fixing holes of the battery rack, affecting the efficiency of fixing and assembly.

[0004] Therefore, there is a need to provide a battery rack and energy storage container to at least partially solve the above problems. Utility Model Content

[0131] The specific embodiments of this application will be described in more detail below with reference to the accompanying drawings, which illustrate representative embodiments of this application and are not intended to limit this application.

[0132] In the process of assembling battery packs and other battery units, related technologies require pushing the battery units to the battery rack assembly position and securing them with fasteners to ensure stability. However, these technologies suffer from insufficient positioning accuracy, which can easily lead to battery unit positional deviations, such as being too far back, too far forward, too far to the left, or too far to the right. This results in the battery units not being able to accurately align with the fixing holes of the battery rack, affecting the efficiency of fixing and assembly.

[0133] To at least solve the aforementioned technical problems, this application provides a battery rack 160 and an energy storage container 100 having the battery rack 160. See below. Figures 1 to 15 To elaborate in detail.

[0134] See Figures 5 to 9 This application provides a battery rack 160 for mounting to an energy storage compartment 110a of an energy storage container 100 to store battery cells in an assembly position. The battery rack 160 includes a rack body 161, a guide rail 162, a fastener 163, a first limiting member 164, and a second limiting member 165. The dimension of the rack body 161 along a first horizontal direction D1 is larger than the dimension of the rack body 161 along a second horizontal direction D2. Any two of the first horizontal direction D1, the second horizontal direction D2, and the vertical direction D3 of the rack body 161 are perpendicular. The rack body 161 is adapted to be fixed to the energy storage compartment 110a. The guide rail 162 is used to mount a pair of oppositely arranged battery cells. The guide rail 162 has a first support portion 162a and a first connecting portion 162b. The first support portion 162a extends along the first horizontal direction D1. The first connecting portion 162b is connected to one side of the first support portion 162a along the second horizontal direction D2 and extends upward. The first connecting portion 162b is detachably connected to the frame body 161. The fixing member 163 is located above the middle portion of the first support portion 162a along the first horizontal direction D1. The fixing member 163 is connected to the first support portion 162a and the first connecting portion 162b. The first limiting member 164 includes a first mounting portion and two first limiting portions. The first mounting portion is connected to the fixing member 163. Along the first horizontal direction D1, the two first limiting portions are located at both ends of the first mounting portion to limit the rear ends of two opposing battery cells at least in the first horizontal direction D1 and the second horizontal direction D2. The second limiting member 165 is located above the first support portion 162a. The second limiting member 165 is connected to the first connecting portion 162b. The second limiting member 165 is spaced apart from the first support portion 162a in the vertical direction D3 to limit the battery cells in the vertical direction D3.

[0135] According to the embodiments of this application, the battery rack 160, when applied to the energy storage container 100, uses a first limiting member 164 to limit the rear end of the battery cell in the first horizontal direction D1 and the second horizontal direction D2, and a second limiting member 165 to limit the battery cell in the vertical direction D3, thereby enabling the positioning of the battery cell. Since the first limiting member 164 has two first limiting parts, it can simultaneously limit the rear ends of two oppositely arranged battery cells. Compared to related technologies that require two limiting structures to limit the two battery cells in the first horizontal direction D1, this application reduces the number of components and simplifies the structure of the battery rack 160, thereby reducing the space occupied by the positioning structure, improving the compatibility of the battery rack 160 with battery cells of more sizes, and also reducing the weight of the battery rack 160.

[0136] In some embodiments, the fastener 163 includes a threaded hole. A first mounting portion is screwed into the threaded hole. It is understood that the first mounting portion has external threads, and the first mounting portion is screwed into the threaded hole of the fastener 163 via the external threads.

[0137] Of course, the first mounting part can be detachably installed to the fastener 163 by means other than screwing, such as snap-fitting.

[0138] By detachably installing the first mounting part to the fixing member 163, it is convenient to replace the first limiting member 164 as needed for maintenance, etc.

[0139] In some other embodiments, the first mounting part is fixed to the fastener 163 by a method that is difficult to disassemble, such as welding.

[0140] In some embodiments, the first mounting portion and the first limiting portion are integrally formed. This helps to enhance the strength and stability of the connection structure between the first mounting portion and the first limiting portion.

[0141] In some other embodiments, the first mounting part may be fixed to the first limiting part by means of welding or other methods.

[0142] See Figures 6 to 8 In some embodiments, the cross-sectional area of ​​the first limiting part perpendicular to the first horizontal direction D1 is reduced in the direction parallel to the first horizontal direction D1 and away from the mounting part. During the movement of the battery cell box assembly position, the first limiting part has a certain guiding function, which helps the first limiting part to connect more easily to the positioning hole at the rear end of the battery cell, and also helps to overcome the error of the installation position of the first limiting member 164 itself to ensure reliable positioning of the battery cell.

[0143] Optionally, the first limiting part is conical.

[0144] In some embodiments, the fastener 163 is a sheet metal part. The fastener 163 is fixed between the first support portion 162a and the first connecting portion 162b by means of welding or the like.

[0145] See Figures 6 to 8 In some embodiments, the second limiting member 165 includes a second limiting portion 165a and two first guide portions 165b. The second limiting portion 165a extends along a first horizontal direction D1. The two first guide portions 165b are connected to the two ends of the second limiting portion 165a along the first horizontal direction D1. In a direction parallel to the first horizontal direction D1 and away from the second limiting portion 165a, the distance between the first guide portion 165b and the first support portion 162a increases. The second limiting portion 165a is used to limit the battery cell in the vertical direction D3. During the movement of the battery cell to the assembly position, one of the two first guide portions 165b, closer to the end of the guide rail 162, guides the battery cell to gradually move below the second limiting portion 165a. Compared to not having a first guide portion 165b, this allows the battery cell to move more accurately and smoothly into the space between the second limiting portion 165a and the first support portion 162a, preventing interference between the battery cell and the second limiting portion 165a. The second limiting part 165a and the first support part 162a cooperate to limit the battery cell in the vertical direction D3. During the process of the battery cell leaving the assembly position, the first guide part 165b, the one furthest from the end of the guide rail 162, guides the battery cell to gradually leave the second limiting part 165a. Compared to not having a first guide part 165b, this allows the battery cell to leave the space between the second limiting part 165a and the first support part 162a more accurately and smoothly, preventing interference between the battery cell and the second limiting part 165a. Furthermore, with the first guide part 165b, compared to a solution without it, the distance between the second limiting part 165a and the first support part 162a can be made smaller, and the second limiting part 165a can even be positioned close to the battery cell in the assembly position, thereby further improving the positioning accuracy in the vertical direction D3.

[0146] Optionally, the second limiting member 165 is a bent member.

[0147] See Figures 5 to 9Optionally, threaded holes are provided on both sides of the main body of the frame along the second horizontal direction D2. Mounting holes are provided on the guide rail 162. The guide rail 162 is fastened to the threaded holes by bolts. When the battery rack 160 is applied to the energy storage container 100, if the battery rack 160 is located at the end of the energy storage compartment 110a, the guide rail 162 is installed on one side of the main body of the battery rack 160. When the battery rack 160 is applied to the energy storage container 100, if the battery rack 160 is not located at the end of the energy storage compartment 110a, the guide rail 162 is installed on both sides of the main body of the battery rack 160.

[0148] See Figures 6 to 8 Optionally, the guide rail 162 also includes a bent flange formed on the upper part of the first connecting portion 162b. By providing the bent flange, the structural strength of the guide rail 162 can be enhanced.

[0149] See Figure 5 , Figure 6 as well as Figure 8 In some embodiments, the frame body includes a top crossbeam 161a, a central column 161b, and two sets of side columns 161c. The top crossbeam 161a extends along a first horizontal direction D1. Both ends of the top crossbeam 161a are adapted to be fixed to the top side beam 113 of the energy storage container 100. The central column 161b extends along a vertical direction D3. The upper end of the central column 161b is fixed to the lower part of the top crossbeam 161a. The lower end of the central column 161b is adapted to be fixed to the bottom longitudinal beam 123 of the energy storage container 100. The two sets of side columns 161c are located on both sides of the central column 161b along the first horizontal direction D1. The side columns 161c are parallel to the central column 161b. The upper ends of the side columns 161c are fixed to the lower part of the top crossbeam 161a. The lower ends of the side columns 161c are adapted to be fixed to the bottom crossbeam 125 of the energy storage container 100. The guide rail 162 is detachably connected to the middle column 161b and the side column 161c.

[0150] Optionally, both the central column 161b and the side columns 161c are provided with threaded holes. The guide rail 162 is connected to the threaded holes by bolts.

[0151] See Figure 6 In addition, the battery rack 160 also includes support and positioning components 161d. Multiple support and positioning components 161d are provided below the guide rail 162. These components are respectively fixed to the central column 161b and the side columns 161c. The support and positioning components 161d are used to support and position the guide rail 162. This arrangement of the support and positioning components 161d facilitates the support and positioning of the guide rail 162, thereby aiding in the assembly of the guide rail 162 with the central column 161b and the side columns 161c.

[0152] Optionally, the battery rack 160 is provided with multiple layers of support and positioning members 161d on either side along the second horizontal direction D2. The number of each layer of support and positioning members 161d is equal to the sum of the number of intermediate columns 161b and the number of side columns 161c.

[0153] See Figure 6 In some embodiments, the guide rail 162 includes a first fastening connection portion 162c at each end along the first horizontal direction D1. The battery holder 160 also includes a first stop 166a and a first locking member 166b. The first stop 166a is detachably connected to the first fastening connection portion 162c. The first locking member 166b is movably connected to the first stop 166a. The first locking member 166b is adapted to be detachably connected to the front end of the battery cell. After the battery cell is assembled into the mounting position of the guide rail 162, the battery cell is prevented from disengaging from the guide rail 162 along the first horizontal direction D1 by bolting the first stop 166a to the end of the guide rail 162, and then the battery cell is fastened to the first stop 166a by the first locking member 166b, thereby more reliably preventing the movement of the battery cell.

[0154] See Figure 5 , Figure 6 ,as well as Figure 8 In some embodiments, the battery rack 160 further includes a high-voltage box mounting member 167. The high-voltage box mounting member 167 is located at the lower part of the rack body and below the guide rail 162. The high-voltage box mounting member 167 is detachably connected to the rack body. The high-voltage box mounting member 167 extends generally along a first horizontal direction D1. The high-voltage box mounting member 167 includes two opposing box-limiting structures 167c. The two box-limiting structures 167c are arranged opposite each other in the first horizontal direction D1. Each box-limiting structure 167c is adapted to limit one high-voltage box. Compared to the conventional technology of placing the high-voltage box mounting structure on the upper part of the battery rack 160, this reduces the space occupied on the upper part of the battery rack 160. In cases where other structures, such as the explosion-proof components mentioned below, need to be arranged on the upper part of the energy storage container 100, it is beneficial to avoid accommodating these structures.

[0155] See Figure 8Furthermore, the high-voltage box mounting component 167 includes a second support portion 167a and a second connecting portion 167b. The second support portion 167a extends along a first horizontal direction D1. The second support portion 167a is used to support the battery unit. The second connecting portion 167b is connected to one side of the second support portion 167a along a second horizontal direction D2 and extends upward. The first connecting portion 162b is detachably connected to the frame body 161. The box limiting structure 167c is located above the second support portion 167a. The box limiting structure 167c is connected to the second connecting portion 167b. The box limiting structure 167c includes a first limiting structure 167d and a second limiting structure 167e. In the first horizontal direction D1, the distance between the first limiting structure 167d and the other box limiting structure 167c is less than the distance between the second limiting structure 167e and the other box limiting structure 167c. The first limiting structure 167d is used to limit the high-voltage box at least in the first horizontal direction D1. The second limiting structure 167e is used to limit the high-voltage box at least in the second horizontal direction D2.

[0156] Optionally, the second connecting part 167b is detachably connected to the frame body 161 by fastening fasteners such as bolts.

[0157] Optionally, the housing limiting structure 167c and the second connecting part 167b are integrally formed.

[0158] Optionally, the high-voltage box mounting component 167 is a sheet metal part made by cutting and bending metal plates.

[0159] See Figure 8Furthermore, the first limiting structure 167d includes a third limiting portion 167d1, a fourth limiting portion 167d2, and a second guide portion 167d3. The third limiting portion 167d1 is connected to the second connecting portion 167b. The third limiting portion 167d1 extends along the second horizontal direction D2. The third limiting portion 167d1 is adapted to position the high-voltage box in the first horizontal direction D1. The fourth limiting portion 167d2 is connected to the upper part of the third limiting portion 167d1. The fourth limiting portion 167d2 extends in a direction parallel to the first horizontal direction D1 and toward the second limiting structure 167e. The fourth limiting portion 167d2 is adapted to limit the high-voltage box in the vertical direction D3. The second guide portion 167d3 is located on the side of the fourth limiting portion 167d2 opposite to the third limiting portion 167d1 and is connected to the fourth limiting portion 167d2. In a direction parallel to the first horizontal direction D1 and away from the other housing limiting structure 167c, the distance between the second guide portion 167d3 and the second support portion 167a increases. The second limiting structure 167e includes a fifth limiting portion 167e1 and a third guide portion 167e2. The fifth limiting portion 167e1 is connected to the second connecting portion 167b via the third guide portion 167e2. In the second horizontal direction D2, the distance between the fifth limiting portion 167e1 and the second connecting portion 167b is greater than the distance between the third guide portion 167e2 and the second connecting portion 167b. In a direction parallel to the first horizontal direction D1 and toward the first limiting structure 167d, the distance between the third guide portion 167e2 and the second connecting portion 167b increases along the second horizontal direction D2. The fifth limiting portion 167e1 is adapted to limit the high-voltage box along the second horizontal direction D2.

[0160] See Figure 5 , Figure 6 as well as Figure 8 Optionally, a first weight-reduction notch 167b1 is provided in the second connecting portion 167b between the two enclosure limiting structures 167c. A second weight-reduction notch 167b2 is provided in the second connecting portion 167b between the first limiting structure 167d and the second limiting structure 167e. By providing the first weight-reduction notch 167b1 and the second weight-reduction notch 167b2, the weight of the high-voltage box mounting component 167 can be reduced.

[0161] See Figure 6 and Figure 8 In some embodiments, the high-voltage box mounting member 167 includes second fastening connection portions 167f at both ends along the first horizontal direction D1. The second fastening connection portions 167f are adapted to be detachably connected to the high-voltage box.

[0162] Optionally, the second fastening connection 167f includes a hole. The second fastening connection 167f is detachably connected to the battery cell by bolts.

[0163] In an embodiment not shown, the battery rack 160 further includes a second stop, such as a first stop 166a, and a second locking member, such as a first locking member 166b. The second stop is bolted to the end of the second connection 167b. The second locking member is movably connected to the second stop for detachable connection to the high-voltage box to secure the high-voltage box to the high-voltage box mounting member 167.

[0164] See Figure 5 , Figure 6 as well as Figure 8 In some embodiments, the battery rack 160 further includes a liquid cooling mount 168. The liquid cooling mount 168 is fixed to the rack body. The liquid cooling mount 168 is adapted to hold liquid cooling pipes.

[0165] See Figures 1 to 5 ,as well as Figure 9 This application provides an energy storage container 100. The energy storage container 100 includes a container body 110, the aforementioned battery rack 160, and battery cells. The container body 110 includes an energy storage compartment 110a. The battery rack 160 is located in the energy storage compartment 110a and fixed to the container body 110. The first horizontal direction D1 of the rack body coincides with the width direction DW of the container body 110. Battery cells located in their assembly positions are supported between adjacent battery racks 160.

[0166] According to the embodiments of this application, the energy storage container 100, by applying the battery rack 160 described above, can accurately position the battery cells while reducing the number of parts and simplifying the structure of the battery rack 160. This helps to reduce the occupancy of the first limiting member 164, thereby improving the compatibility of the energy storage container 100 with battery cells of different sizes, and also helps to reduce the weight of the energy storage container 100.

[0167] See Figures 1 to 5In some embodiments, the container 110 includes a base frame 120, a first top plate 111 corresponding to the energy storage compartment 110a, and a top side beam 113. The lower end of the battery rack 160 is fixed to the base frame 120. The rack body includes a top crossbeam 161a. The top crossbeam 161a extends along the width direction DW of the container 110. The top crossbeam 161a is supported on the lower part of the first top plate 111. The end of the top crossbeam 161a along the width direction DW is fixed to the top side beam 113. The top plate has an explosion-proof opening 111a. The explosion-proof opening 111a is located between the top crossbeams 161a of two adjacent battery racks 160. The energy storage container 100 also includes an explosion-proof device 150. The explosion-proof device 150 includes an explosion-proof component (not shown), an explosion-proof support assembly 153, and an explosion-proof mounting assembly 154. The explosion-proof component is located at the explosion-proof opening 111a. An explosion-proof support assembly 153 is fixed to the top crossbeam 161a at the explosion-proof port 111a. The explosion-proof support assembly 153 supports the bottom of the explosion-proof component. An explosion-proof mounting assembly 154 is located around the explosion-proof port 111a. The explosion-proof mounting assembly 154 is detachably connected to the explosion-proof component. The top crossbeam 161a supports the first top plate 111. The connection between the explosion-proof support assembly 153 and the top crossbeam 161a enhances the strength of the explosion-proof support assembly 153 in supporting the explosion-proof component. By providing the explosion-proof mounting assembly 154, the explosion-proof component can be installed on the top of the enclosure 110. Because the explosion-proof mounting assembly 154 is detachably connected to the explosion-proof component, it is convenient to replace the explosion-proof component after it is damaged. The explosion-proof component is configured to fail when the pressure inside the energy storage compartment 110a exceeds the limit, thereby releasing pressure from the explosion-proof port 111a.

[0168] See Figure 5 Furthermore, the energy storage container 100 also includes explosion-proof connecting beams 152. The explosion-proof connecting beams 152 are located below the first top plate 111. A pair of explosion-proof connecting beams 152 are provided at each explosion-proof opening 111a. The pair of explosion-proof connecting beams 152 are located on both sides of the explosion-proof opening 111a along the width direction DW. The explosion-proof connecting beams 152 are connected to adjacent top crossbeams 161a. Explosion-proof support assemblies 153 are connected to the explosion-proof connecting beams 152 and top crossbeams 161a, which further improves the load-bearing capacity of the explosion-proof support assembly 153 to accommodate the installation of explosion-proof components of different weights.

[0169] See Figure 3 and Figure 5 Furthermore, the explosion-proof support assembly 153 includes a first support beam 153a and a second support beam 153b. The first support beam 153a and the second support beam 153b are connected. The first support beam 153a extends along the length direction DL of the housing 110 and is connected to the adjacent top crossbeam 161a. The second support beam 153b extends along the width direction DW and is connected to the explosion-proof connecting beam 152.

[0170] Optionally, there is one first support beam 153a and one second support beam 153b. Thus, the explosion-proof support assembly 153 is constructed as a cross-shaped support frame formed by assembling the first support beam 153a and the second support beam 153b. This simplifies the structure of the explosion-proof support assembly 153 while providing support for the explosion-proof component.

[0171] It is understood that in other embodiments, the number of the first support beam 153a and the second support beam 153b may be any number other than one.

[0172] See Figure 2 and Figure 5 Furthermore, the explosion-proof mounting assembly 154 includes an explosion-proof mounting frame 154a and an explosion-proof fastener 154b. The explosion-proof mounting frame 154a is disposed around the explosion-proof port 111a and fixed to the first top plate 111. The top of the explosion-proof mounting frame 154a is higher than the top of the explosion-proof support assembly 153. In the height direction DH of the housing 110, the distance between the top of the explosion-proof mounting frame 154a and the top of the explosion-proof support assembly 153 is less than or equal to the size of the explosion-proof component. The explosion-proof fastener 154b is detachably connected to the explosion-proof component and the explosion-proof mounting frame 154a.

[0173] See Figure 1 , Figure 2 and Figure 9In addition, the container 110 also includes an electrical control compartment 110b. The electrical control compartment 110b and the energy storage compartment 110a are arranged along the length direction DL of the container 110. The container 110 includes an end wall 114 and a first end door 115. The end wall 114 and the first end door 115 are located at both ends of the container 110 along the length direction DL. The first end door 115 is arranged correspondingly to the electrical control compartment 110b. The energy storage container 100 also includes an electrical control device 181, a first dehumidifier (not shown), a second dehumidifier 182, a first drain pipe 183, and a second drain pipe 184. The electrical control device 181 is located in the electrical control compartment 110b. The first dehumidifier is fixed to the first end door 115 and adapted to face the side of the electrical control compartment 110b. The first drain pipe 183 is provided through the first end door 115. One end of the first drain pipe 183 is connected to the first dehumidifier. The other end of the first drain pipe 183 extends to the outside of the first end door 115. The second dehumidifier 182 is installed to the end wall 114. A second drain pipe 184 passes through the end wall 114. One end of the second drain pipe 184 is connected to the second dehumidifier 182. The other end of the second drain pipe 184 extends to the outside of the first end door 115. By installing the first and second dehumidifiers 182, the humidity of the electrical control compartment 110b and the energy storage compartment 110a can be adjusted. By installing the first drain pipe 183 and the second drain pipe 184, the water generated by the first and second dehumidifiers 182 during dehumidification can be drained, preventing electrical faults such as short circuits or corrosion that could affect the service life of the compartment due to water dripping inside.

[0174] See Figure 2 Furthermore, the housing 110 includes a sill beam 131. The sill beam 131 corresponds to the first end door 115. Along the length DL of the housing 110, the other end of the first drain pipe 183 protrudes outward from the sill beam 131 when the first end door 115 is closed. This prevents water droplets from the first drain pipe 183 from falling onto the sill beam 131, thereby improving the waterproof performance of the first end door 115 and extending the service life of the sill beam 131.

[0175] Optionally, the first end door 115 is locked to the threshold beam 131 and the lintel using a rod lock 115a.

[0176] See Figure 1 Furthermore, the container 110 includes a bottom end beam 132. The bottom end beam 132 corresponds to the end wall 114. In the longitudinal direction DL of the container 110, the other end of the second drain pipe 184 protrudes outward from the bottom end beam 132. This prevents water discharged from the second drain pipe 184 from dripping onto the bottom end beam 132, thereby improving the waterproof performance of the energy storage container 100 and extending the service life of the bottom end beam 132.

[0177] It is understandable that an openable and closable energy storage compartment door 118 is provided on the side of the housing 110 corresponding to the energy storage compartment 110a.

[0178] See Figure 2 Optionally, an openable and closable maintenance door 119 is provided on the side of the enclosure 110 corresponding to the electrical control compartment 110b. The maintenance door 119 is suitable for personnel to perform routine maintenance on the equipment inside the electrical control compartment 110b. Compared to the first end door 115 with a lever lock 115a, the opening and closing of the maintenance door 119 is more flexible and convenient. In cases such as the installation of electrical control equipment 181 or the need for extensive maintenance, the corresponding operations can be performed by opening the first end door 115.

[0179] See Figure 2 , Figure 4 as well as Figure 9 In some embodiments, the enclosure 110 further includes a liquid cooling chamber 110c. The liquid cooling chamber 110c and the electrical control chamber 110b are located on one side of the energy storage chamber 110a along the length direction DL of the enclosure 110. The liquid cooling chamber 110c and the electrical control chamber 110b are arranged along the width direction DW. The enclosure 110 also includes a second end door 116 corresponding to the liquid cooling chamber 110c. The enclosure 110 includes a first liquid cooling ventilation window 116a and a second liquid cooling ventilation window 110d. The first liquid cooling ventilation window 116a is disposed at the second end door 116, and the second liquid cooling ventilation window 110d is located on the side of the liquid cooling chamber 110c facing away from the electrical control chamber 110b. The second liquid cooling ventilation window 110d is arranged correspondingly to the liquid cooling chamber 110c. By providing the second end door 116, it is convenient to install liquid cooling equipment and to maintain and repair the liquid cooling equipment. By providing a first liquid-cooled ventilation window 116a and a second liquid-cooled ventilation window 110d at the second end door 116, ventilation and heat exchange of the liquid-cooled equipment are facilitated. The liquid-cooled equipment is used to cool each battery cell using liquid cooling.

[0180] See Figure 1 and Figure 2In some embodiments, the electronic control compartment 110b and the energy storage compartment 110a are arranged along the length DL of the housing 110. The housing 110 also includes an energy storage air inlet window 110f and an energy storage air outlet window 110e. The energy storage air inlet window 110f is located at the end of the energy storage compartment 110a adjacent to the electronic control compartment 110b. The energy storage air outlet window 110e is located at the end of the energy storage compartment 110a away from the electronic control compartment 110b. The energy storage air outlet window 110e is higher than the energy storage air inlet window 110f. The energy storage air outlet window 110e is used for air outlet. The energy storage air inlet window 110f is used for air inlet. During the process of cooling the energy storage compartment 110a using air cooling, the cooler air enters the energy storage compartment 110a through the energy storage air inlet window 110f, and the air that has absorbed heat is discharged from the energy storage compartment 110a through the energy storage air outlet window 110e. By placing the energy storage inlet vent 110f and the energy storage outlet vent 110e at both ends of the energy storage compartment 110a, with the outlet vent 110e higher than the inlet vent 110f, the heat exchange area between the airflow and the battery rack 160 and battery cells can be increased, thereby improving heat exchange efficiency. Since the coolant in the energy storage compartment 110a is toxic, the inlet vent 110f and outlet vent 110e facilitate ventilation between the energy storage compartment 110a and the outside of the housing 110, preventing coolant vapor from accumulating inside the energy storage compartment 110a.

[0181] See Figures 1 to 5 ,as well as Figure 9 In addition, the enclosure 110 also includes a second top plate 112, a first partition wall 117a, an intermediate column 106, and a second partition wall 117b. The second top plate 112 is located on top of the electrical control compartment 110b and the liquid cooling compartment 110c. The second top plate 112 is fixed to the top side beam 113. The first partition wall 117a is located inside the enclosure 110 and extends along the width direction DW. The intermediate column 106 is fixed to the upper part of the sill beam 131. The first end door 115 is located between the corner column 101 and the intermediate column 106. The first partition wall 117a is spaced apart from the end wall 114 and the first end door 115, respectively. The second partition wall 117b connects the first partition wall 117a and the intermediate column 106. The electrical control compartment 110b and the liquid cooling compartment 110c are formed on both sides of the second partition wall 117b.

[0182] Optionally, the first top plate 111 is a flat plate structure. The second top plate 112 is a corrugated plate.

[0183] In the related technology, the energy storage container 100 has a flat floor structure, which is a weak part of the load-bearing capacity of the base frame 120. Therefore, the overall strength of the base frame 120 is not high, the load-bearing capacity is weak, and it is difficult to meet the application requirements of higher load.

[0184] See Figures 11 to 15According to an embodiment of this application, the base frame 120 has a battery carrying area 121 and an electrical carrying area 122. The battery carrying area 121 and the electrical carrying area 122 are arranged along the length direction DL of the base frame 120. The battery carrying area 121 is adapted to house energy storage batteries. The electrical carrying area 122 is adapted to house at least electrical control equipment 181. The base frame 120 includes a bottom longitudinal beam 123, a pair of bottom side beams 124, two sets of bottom cross beams 125, and two sets of first floor panels 126. The bottom longitudinal beam 123 extends along the length direction DL. The pair of bottom side beams 124 are located on both sides of the bottom longitudinal beam 123 along the width direction DW of the base frame 120. The bottom side beams 124 are parallel to the bottom longitudinal beam 123. The two sets of bottom cross beams 125 are located on both sides of the bottom longitudinal beam 123 along the width direction DW. The bottom cross beams 125 extend along the width direction DW. The two ends of the bottom cross beams 125 are respectively connected to the bottom longitudinal beam 123 and the bottom side beams 124. Each set of bottom crossbeams 125 includes multiple bottom crossbeams 125. The multiple bottom crossbeams 125 are arranged at intervals along the length direction DL. Two sets of first floor panels 126 are located in the battery support area 121. The two sets of first floor panels 126 are located on both sides of the bottom longitudinal beam 123 along the width direction DW. Each set of first floor panels 126 includes multiple first floor panels 126. The two ends of the first floor panels 126 along the width direction DW are respectively connected to the bottom longitudinal beam 123 and the bottom side beam 124. The ends of the first floor panels 126 along the width direction DW are connected to the bottom crossbeams 125. In the height direction DH of the base frame 120, the end of the first floor panel 126 near the bottom longitudinal beam 123 is higher than the end of the first floor panel 126 near the bottom side beam 124. The first floor panel 126 includes a bent portion. Furthermore, the first floor panel 126 is lower than the top surface of the bottom crossbeams 125 and the top surface of the bottom longitudinal beam 123. The first floor 126, the bottom longitudinal beam 123, the bottom transverse beam 125, and the bottom side beam 124 enclose and form a receiving groove 127.

[0185] According to the embodiment of this application, the base frame 120, by configuring the first floor 126 located in the battery bearing area 121 such that "the end of the first floor 126 near the bottom longitudinal beam 123 is higher than the end of the first floor 126 near the bottom side beam 124", can guide the liquid to flow towards the bottom side beam 124. This prevents the liquid from accumulating in the middle of the width direction DW of the base frame 120, and allows the liquid to be collected by the receiving grooves 127 and isolated by the bottom crossbeams 125 to prevent the liquid from flowing freely. This makes the distribution range of the liquid in the upper part of the base frame 120 controllable, reducing the risk of water accumulation. Moreover, by providing a bending portion in the first floor 126, the bending resistance of the first floor 126 can be enhanced. Compared with a flat floor, this is beneficial to improving the overall strength of the base frame 120, thereby improving the load-bearing capacity of the base frame 120 and enabling it to meet the application requirements of greater load weight. When the base frame 120 is applied to a container, the total weight of goods or equipment that the container can carry can be increased.

[0186] See Figure 14 In some embodiments, the first floor 126 includes a first plate 126a and a second plate 126b connected sequentially along the width direction DW. The first plate 126a and the second plate 126b are arranged intersectingly. The end of the first plate 126a away from the second plate 126b is connected to the bottom longitudinal beam 123. The end of the second plate 126b away from the first plate 126a is connected to the bottom side beam 124. A bend is formed at the connection between the first plate 126a and the second plate 126b. When liquid drips onto the first plate 126a, the liquid flows from the first plate 126a to the second plate 126b until it reaches the lowest point of the second plate 126b. When liquid drips onto the second plate 126b, the liquid flows from the point where it drips onto the second plate 126b to the lowest point of the second plate 126b until it reaches the lowest point of the second plate 126b. By configuring the first floor 126 to have intersecting first plate 126a and second plate 126b, the overall outline of the first floor 126 is V-shaped or other shapes similar to V, thereby improving the structural strength of the first floor 126 while simplifying its structure, and thus facilitating the processing and manufacturing of the first floor 126.

[0187] See Figures 11 to 14In addition, the base frame 120 also includes a drain assembly 140 and a connecting pipe 145. The drain assembly 140 is disposed at one end of the first floor 126 near the bottom side beam 124. At least a portion of the connecting pipe 145 is embedded in the bottom cross beam 125. The connecting pipe 145 extends along the length direction DL. The connecting pipe 145 is arranged corresponding to the end of the first floor 126 near the bottom side beam 124. The connecting pipe 145 connects to an adjacent receiving tank 127. The drain assembly 140 is used to drain liquid from the receiving tank 127 when it is open, and to retain liquid in the receiving tank 127 when it is closed. By providing the connecting pipe 145 to connect adjacent receiving tanks 127, liquid can flow through the connecting pipe 145 to the receiving tank 127 where the drain assembly 140 is provided, thus eliminating the need to provide a drain assembly 140 in each receiving tank 127. Compared to the approach of installing a drain assembly 140 in each receiving tank 127, installing a connecting pipe 145 and placing the drain assembly 140 in only a portion of the receiving tanks 127 reduces costs and simplifies the operation when draining liquid. Furthermore, since the receiving tanks 127 are interconnected via the connecting pipe 145, the liquid level in each receiving tank 127 can remain consistent even when the drain assembly 140 is closed. This helps prevent electrical short circuits and other malfunctions caused by excessively high liquid levels in some receiving tanks 127, thereby improving electrical safety.

[0188] exist Figure 11 and Figure 12 In the example shown, the base frame 120 is equipped with two drain assemblies 140. The two drain assemblies 140 are located on both sides of the bottom longitudinal beam 123. In the length direction DL, the drain assemblies 140 are located in the middle of the battery carrying area 121. This reduces the number of drain assemblies 140 while improving the efficiency of liquid collection from the receiving tank 127 without drain assemblies 140 to the receiving tank 127 with drain assemblies 140.

[0189] Optionally, the bottom crossbeam 125 has mounting holes. The connecting pipe 145 passes through the mounting holes and is welded to the bottom crossbeam 125.

[0190] See Figure 15Furthermore, the drain assembly 140 includes a liquid receiving member 141, a drain pipe 142, and a plug 143. The upper part of the liquid receiving member 141 has a groove suitable for receiving liquid. The groove is flared, wider at the top and narrower at the bottom. The upper part of the drain pipe 142 is connected to the liquid receiving member 141 and communicates with the receiving tank 127 through the liquid receiving member 141. The plug 143 is detachably connected to the lower end of the drain pipe 142 by a screw connection or other detachable connection method. When the plug 143 is connected to the drain pipe 142, the drain assembly 140 is in a closed state, preventing liquid discharge. When the plug 143 is detached from the drain pipe 142, the drain assembly 140 is in an open state, allowing liquid to drain, thereby achieving the purpose of draining liquid.

[0191] See Figure 11 and Figure 12 In an embodiment of this application, the bottom longitudinal beam 123 includes a first longitudinal beam segment 123a and a second longitudinal beam segment 123b arranged sequentially along the length direction DL. The top surface of the first longitudinal beam segment 123a is higher than the top surface of the second longitudinal beam segment 123b. The first longitudinal beam segment 123a is located in the battery carrying area 121. The second longitudinal beam segment 123b is at least partially located in the electrical carrying area 122. The first floor 126 is lower than the top surface of the bottom crossbeam 125. The bottom crossbeam 125 is lower than the top surface of the first longitudinal beam segment 123a. The top surface of the bottom crossbeam 125 is flush with the top surface of the second longitudinal beam segment 123b. The base frame 120 also includes a second floor 128. The second floor 128 is located in the electrical carrying area 122. The second floor 128 is connected to the upper part of the second longitudinal beam segment 123b and the upper part of the bottom crossbeam 125. By setting the top surface of the second longitudinal beam segment 123b corresponding to the electrical load-bearing area 122 to be flush with the top surface of the bottom crossbeam 125, and setting the top surface of the first longitudinal beam segment 123a corresponding to the battery load-bearing area 121 to be higher than the top surface of the bottom crossbeam 125, the structural strength and load-bearing capacity of the base frame 120 in the battery load-bearing area 121 can be improved. On the other hand, the height of the second floor 128 can be reduced, so that more space can be reserved for equipment such as electrical control cabinets in the height direction DH, thereby allowing the installation of equipment with larger height dimensions and improving the compatibility of equipment selection.

[0192] Continue reading Figure 11 and Figure 12 Optionally, a portion of the second longitudinal beam segment 123b is located in the battery bearing area 121. This portion of the second longitudinal beam segment 123b is used to avoid certain hardware structures or for wiring.

[0193] See also Figure 11 and Figure 12Optionally, the electrical bearing area 122 is provided with two second floor panels 128. The two second floor panels 128 are distributed along the width direction DW on both sides of the bottom longitudinal beam 123. The upper part of one second floor panel 128 is used to install liquid cooling equipment. The upper part of the other second floor panel 128 is used to install electrical control equipment 181. The second floor panel 128 used for accommodating the electrical control equipment 181 has through holes 128a. The through holes 128a are used for cable routing.

[0194] See Figure 11 , Figure 14 as well as Figure 15 In addition, a bottom sealing plate 129 is provided at the lower part of the base frame 120. The bottom sealing plate 129 is connected to the lower part of the bottom longitudinal beam 123, the lower part of the bottom side beam 124, and the lower part of the bottom cross beam 125. The bottom sealing plate 129 is used to close the open structure at the lower part of the base frame 120 to improve the integrity, flatness, and aesthetics of the lower part of the base frame 120.

[0195] Furthermore, the underframe 120 includes two bottom side beams 124. One of the bottom side beams 124 has a clearance notch 124a at one end corresponding to the energy storage container 100. The clearance notch 124a is recessed into the bottom side beam 124 along the length direction DL of the energy storage container 100. The clearance notch 124a is used to accommodate the corner post 101. The four corners of the underframe 120 are each provided with a mounting notch 120a. The mounting notch 120a is used to mount the corner bracket 103. When the underframe 120 is applied to the energy storage container 100, part of the corner post 101 mounted to the clearance notch 124a is located in the clearance notch 124a, and the other part corresponds to the mounting notch 120a, thereby allowing the corner post 101 corresponding to the clearance notch 124a to be closer to the center of the energy storage container 100 along the length direction DL relative to the corner bracket 103. This facilitates the installation of the door hinge 102, prevents the door hinge 102 from protruding outside the corner piece 103, and also helps to reduce the complexity of the door frame structure of the end door.

[0196] Optionally, the base frame 120 also includes a grounding element 133 disposed on the bottom side beam 124.

[0197] In related technologies, the outer surface of the rear corner post 101 of the energy storage container 100 typically protrudes from the outer surface of the rear door panel and is flush with the outer surface of the rear bottom corner piece 103. The rear corner post 101 typically includes an inner corner post 101 and an outer corner post 101 that abuts against the inner corner post 101; that is, the outer surface of the outer corner post 101 protrudes from the outer surface of the rear door panel. To achieve a seal on the rear door panel, the outer corner post 101 needs to be recessed inward along the length direction DL of the container until it is flush with the rear door panel. To achieve a fixed connection between the outer corner post 101 and the inner corner post 101, welding is usually required, which greatly reduces production efficiency and increases production costs. Furthermore, welding deformation is prone to occur during welding.

[0198] like Figures 2 to 9 As shown, the energy storage container 100 includes corner posts 101, door hinges 102, a first end door 115, corner fittings 103, a stepped surface, and reinforcing members 104. The interior of the energy storage container 100 can be equipped with devices such as battery units and battery management systems as needed.

[0199] like Figure 1 , Figure 2 as well as Figure 9 As shown, according to the energy storage container 100 of this application, the corner post 101 of the energy storage container 100 has a rectangular cross-section. Specifically, the cross-section of the corner post 101 can be square or rectangular. A door hinge 102 is disposed on the first outer surface of the corner post 101. The first outer surface refers to one side of the rear end face of the energy storage container 100 as shown in the figure. A first end door 115 is pivotally connected to the corner post 101 via the door hinge 102. The first end door 115 in the closed state is flush with the corner post 101. Specifically, the outer side of the first end door 115 in the closed state is flush with the first outer surface of the corner post 101. The first outer surface of the corner post 101 is the surface of the corner post 101 facing outward along its length direction DL.

[0200] Two corner pieces 103 are respectively disposed at the top and bottom of the corner post 101, and the outer surface of the corner piece 103 protrudes from the first outer surface of the corner post 101 to the first distance along the length direction DL and forms a stepped surface, so that the door hinge 102 does not exceed the corner piece 103.

[0201] Two reinforcing members 104 are disposed at the top and bottom ends of the first outer surface of the corner post 101 and are respectively connected to the corresponding corner pieces 103. The corner post 101 of this application has a rectangular cross-sectional shape. Compared with the existing corner post 101 with an L-shaped cross-section, the corner post 101 of this application is directly integral, eliminating the welding process and reducing the risk of welding deformation. This significantly reduces the production cost of the energy storage container 100. At the same time, compared with the existing corner post 101, which is mostly L-shaped in cross-section, the corner post 101 of this application has a rectangular cross-section, effectively improving the structural strength of the corner post 101 by replacing the existing L-shaped corner post 101 with the rectangular cross-section of this application.

[0202] It should be noted that, in the illustrated embodiment, the term "length direction DL" refers to the length direction DL along the energy storage container 100 as shown in the figure.

[0203] like Figure 2 As shown, in some preferred embodiments of this application, the corner post 101 for mounting the door hinge 102 protrudes from the connected corner piece 103 along the length direction DL towards the interior of the housing. This effectively ensures the structural strength of the corner post 101.

[0204] like Figure 2 As shown, the reinforcing member 104 is disposed on the stepped surface and connected to the first outer surface of the corner post 101. The provision of the reinforcing member 104 can further and effectively enhance the connection strength between the corner post 101 and the corner piece 103.

[0205] like Figure 2 As shown, the top of the reinforcing member 104 gradually slopes downwards along the length direction DL, so that an inclined surface is constructed at the top of the reinforcing member 104. The inclined surface makes the reinforcing member 104 form a triangular shape, giving it the stability of a triangle, thereby enabling the reinforcing member 104 to have a better stable support function.

[0206] like Figure 2 As shown, the reinforcing member 104 also includes a vertical outer side, the bottom of which is connected to the step surface and the top of which is connected to the inclined surface, and the vertical outer side does not protrude beyond the outer side of the corner piece 103. In this way, the vertical outer side is set perpendicular to the step surface and does not protrude beyond the outer side of the corner piece 103, thereby effectively preventing positional interference of the vertical outer side of the reinforcing member 104 during transportation.

[0207] It should be noted that the surface of the reinforcing member 104 facing the corner post 101 is welded to the corner post 101 as a whole, and the bottom end of the reinforcing member 104 is welded to the stepped surface at the top of the bottom corner piece 103.

[0208] like Figure 2 As shown, in some preferred embodiments of this application, the reinforcing member 104 further includes a welding notch. The opening of the welding notch faces outward and is formed on both sides of the bottom end of the reinforcing member 104. By forming welding notches on both sides of the bottom end of the reinforcing member 104, the weld penetration depth between the reinforcing member 104 and the corner piece 103 can be increased, ensuring complete weld penetration and thus achieving better weld quality. Simultaneously, burn-through can be prevented; the design of the welding notch effectively prevents excessive heat concentration during welding, thereby avoiding weld penetration of the reinforcing member 104 and the formation of holes.

[0209] like Figure 2 As shown, in some preferred embodiments of this application, there are multiple reinforcing members 104, which are spaced apart along the first outer surface of the corner post 101. By adding multiple reinforcing members 104, the connection strength between the corner post 101 and the corner piece 103 can be effectively improved.

[0210] Preferably, the number of reinforcing members 104 can be 2 or 3, etc.

[0211] In one specific embodiment of this application, the reinforcing member 104 is generally trapezoidal.

[0212] like Figure 2 As shown, the corner post 101 is manufactured as a single piece. In this way, compared with the existing corner posts 101, which are mostly made by welding the inner corner post 101 and the outer corner post 101 together, the welding process is eliminated. The corner post 101 selected in this application is a square tube manufactured as a single piece, which will not cause welding deformation, and at the same time, it also effectively saves economic costs.

[0213] like Figure 2 As shown, in some preferred embodiments of this application, the corner post 101 and the corner piece 103 for mounting the door hinge 102 are welded together, which can effectively ensure the connection strength between the corner post 101 and the corner piece 103.

[0214] like Figure 2 As shown, in some preferred embodiments of this application, the energy storage container 100 has an opening on one side (not shown in the figure), and one side of the first end door 115 is hinged to one side of the opening.

[0215] The energy storage container 100 of this application also includes a seal, which is disposed around the first end door 115 and can play a good sealing role.

[0216] In a preferred embodiment of this application, the seal may be made of rubber or silicone, etc.

[0217] It should be noted that the sealing element only needs to meet the sealing performance of the first end door 115, and there is no limitation on the specific material of the sealing element.

[0218] It should also be noted that the corner post 101 and corner fitting 103 of this application adopt a staggered design, so that when the first end door 115 is closed, the outer surface of the first end door 115 is flush with the first outer surface of the corner post 101. In this way, the first end door 115 can be directly welded to the first outer surface of the corner post 101 through the door hinge 102, avoiding the misalignment of the first outer surface of the corner post 101 and the outer surface of the first end door 115 when it is closed along the length direction DL of the energy storage container 100 (i.e., the length direction DL). Furthermore, it eliminates the need to construct a notch in the corner post 101 to provide installation space for the door hinge 102 that is adapted to connect the first end door 115. In this way, it effectively avoids the situation of reducing the structural strength of the corner post 101.

[0219] In related technologies, container wiring harnesses are mainly divided into two categories: low-voltage secondary power and communication lines, and high-voltage power lines. Due to the limited space inside the container, container wiring is mostly located on the sides and bottom of the container, resulting in poor maintainability. In the following description, low-voltage secondary power and communication lines will be referred to as low-voltage lines, and high-voltage power lines will be referred to as high-voltage lines.

[0220] See Figure 5 , Figure 9 and Figure 10In an embodiment of this application, the energy storage container 100 further includes a high-low voltage isolation assembly 170. The high-low voltage isolation assembly 170 is located below the high-voltage box mounting component 167. The high-low voltage isolation assembly 170 includes a first high-low voltage isolation member 171, a second high-low voltage isolation member 172, a third high-low voltage isolation member 173, and a high-low voltage converging member 176. The first high-low voltage isolation member 171 extends along the length direction DL of the energy storage container 100. The second high-low voltage isolation member 172 extends along the length direction DL of the energy storage container 100. The first high-low voltage isolation member 171 and the second high-low voltage isolation member 172 are located on both sides of the bottom longitudinal beam 123. The first high-low voltage isolation member 171 is arranged correspondingly to the electrical control compartment 110b. The high-low voltage converging member 176 is located at the end of the first high-low voltage isolation member 171 facing the electrical control compartment 110b and extends along the length direction DL of the energy storage container 100. The third high-low voltage isolation component 173 extends at least partially along the width direction DW of the energy storage container 100. One end of the third high-low voltage isolation component 173 is connected to the second high-low voltage isolation component 172. The first high-low voltage isolation component 171, the second high-low voltage isolation component 172, and the third high-low voltage isolation component 173 each include a low-voltage line channel 170a and a high-voltage line channel 170b. The low-voltage line channel 170a of the first high-low voltage isolation component 171 and the second high-low voltage isolation component 172 is located at the ends of the first high-low voltage isolation component 171 and the second high-low voltage isolation component 172 that are away from each other along the width direction DW. The low-voltage line channel 170a of the third high-low voltage isolation component 173 is located on the side of the third high-low voltage isolation component 173 that is closer to the electrical control compartment 110b along the length direction DL. The high-voltage line channels 170b of the first high-low voltage isolation component 171 and the second high-low voltage isolation component 172 are connected through the high-voltage line channel 170b of the third high-low voltage isolation component 173. The high-low voltage combining component 176 is connected to the first high-low voltage isolation component 171 and the third high-low voltage isolation component 173. The high-low voltage combining component 176 includes a high-voltage line channel 170b and two low-voltage line channels 170a. In the high-low voltage combining component 176, the two low-voltage line channels 170a are located on both sides of the high-voltage line channel 170b along the width direction DW. The high-voltage line channel 170b of the high-low voltage combining component 176 is connected to the high-voltage line channel 170b of the first high-low voltage isolation component 171 and the high-voltage line channel 170b of the third high-low voltage isolation component 173. One low-voltage line channel 170a of the high-low voltage combining component 176 is connected to the low-voltage line channel 170a of the first high-low voltage isolation component 171. The other low-voltage line channel 170a of the high-low voltage combining component 176 is connected to the low-voltage line channel 170a of the third high-low voltage isolation component 173. The width of the low-voltage line channel 170a is smaller than the width of the high-voltage line channel 170b.The high-low voltage converging component 176 is used to converge the high-voltage and low-voltage cables laid in the first high-low voltage isolation component 171 and the second high-low voltage isolation component 172 and guide them to the electrical control compartment 110b. The third high-low voltage isolation component 173 is used to guide the high-voltage and low-voltage cables laid in the second high-low voltage isolation component 172 to the high-low voltage converging component 176.

[0221] See Figure 10 Furthermore, the first high-low voltage isolation component 171, the second high-low voltage isolation component 172, and the third high-low voltage isolation component 173 have the same cross-sectional shape. Each of these components includes an inner wall 174a, a first intermediate wall 174b, an outer wall 174c, and a first bottom wall 174d. The inner wall 174a and the outer wall 174c are connected to opposite ends of the first bottom wall 174d. The first intermediate wall 174b is fixed to the first bottom wall 174d. The first intermediate wall 174b is spaced apart from both the inner wall 174a and the outer wall 174c. The distance between the first intermediate wall 174b and the inner wall 174a is greater than the distance between the first intermediate wall 174b and the outer wall 174c. The inner wall 174a, the first intermediate wall 174b, and the first bottom wall 174d form a high-voltage line channel 170b. A low-voltage line channel 170a is formed between the first intermediate wall 174b, the outer wall 174c, and the first bottom wall 174d. The first intermediate wall 174b has a first high-voltage cable passage 174b1. The outer wall 174c has a second high-voltage cable passage 174c1 and a low-voltage cable passage 174c2. The first high-voltage cable passage 174b1 and the second high-voltage cable passage 174c1 are aligned to accommodate high-voltage lines. The low-voltage cable passage 174c2 is suitable for accommodating low-voltage lines. The first high-voltage cable passage 174b1, the second high-voltage cable passage 174c1, and the low-voltage cable passage 174c2 are arranged correspondingly to the battery rack 160.

[0222] Optionally, the inner sidewall 174a, the first bottom wall 174d, and the outer sidewall 174c are integrally formed, for example, by sheet metal processing from the same metal sheet. The first intermediate wall 174b is fixed to the first bottom wall 174d by welding or other methods. The first intermediate wall 174b is made of a material capable of isolating electromagnetic interference and other electrical interference signals.

[0223] Continue reading Figure 10Similar to the first high-low voltage isolation component 171, the high-low voltage converging component 176 adds a first intermediate wall 174b, and the width of the bottom wall is adaptively changed. A high-voltage line channel 170b is formed between the two first intermediate walls 174b. The high-low voltage converging component 176 specifically includes a first wall 175a, two second intermediate walls 175b, a second wall 175c, and a second bottom wall 175d. The first wall 175a is aligned with and connected to the outer wall 174c of the first high-low voltage isolation component 171. The second wall 175c corresponds to and is connected to the outer wall 174c of the third high-low voltage isolation component 173. One of the two second intermediate walls 175b forms a low-voltage line channel 170a with the first wall 175a and the second bottom wall 175d, which is used to connect the low-voltage line channel 170a of the first high-low voltage isolation component 171. Another low-voltage line channel 170a is formed between the other of the two second intermediate walls 175b and the second wall 175c and the second bottom wall 175d, for connecting the low-voltage line channel 170a of the third high-low voltage isolation member 173.

[0224] Optionally, the first wall 175a, the second bottom wall 175d, and the second wall 175c are integrally formed, for example, by sheet metal processing from the same metal sheet. The second intermediate wall 175b is fixed to the bottom wall by welding or other methods. The second intermediate wall 175b is made of a material capable of isolating electromagnetic interference and other electrical interference signals.

[0225] See also Figure 10 In addition, the high-low voltage isolation assembly 170 also includes a low-voltage gathering member 176. The low-voltage gathering member 176 is located on the side of the first high-low voltage isolation assembly 171 and the second high-low voltage isolation assembly 172 away from the electrical control compartment 110b. The low-voltage gathering member 176 is connected to the first high-low voltage isolation assembly 171 and the second high-low voltage isolation assembly 172. The low-voltage gathering member 176 forms a low-voltage gathering channel 176a. The low-voltage gathering channel 176a connects to the low-voltage line channel 170a of the first high-low voltage isolation assembly 171 and the low-voltage line channel 170a of the second high-low voltage isolation assembly 172. By adding the low-voltage gathering member 176, a low-voltage line can be laid across the bottom longitudinal beam 123 along the width direction DW at the end away from the electrical control compartment 110b.

[0226] Optionally, the low-voltage collection component 176 is a sheet metal part. The main structure of the low-voltage collection component 176 has a U-shaped cross-section. A bent structure is formed at the top of the channel wall on the side of the low-voltage collection component 176 away from the electrical control compartment 110b. The bent structure extends toward the electrical control compartment 110b. The bent structure is used to prevent the low-voltage lines located in the low-voltage collection channel 176a from detaching upward from the low-voltage collection component 176.

[0227] See Figure 10In some embodiments, the high-low voltage isolation assembly 170 further includes a plurality of support legs 177.
