Description

Technical Field

[0001] The present application generally relates to the technical field of container structures, and more particularly to a battery rack and an energy storage container. Background Art

[0002] As the energy storage industry develops, energy storage containers, as an emerging energy storage solution, are experiencing continuous technological advancements. Energy storage containers typically house battery packs, such as lithium-ion batteries, to efficiently store large amounts of energy. Battery racks are responsible for mounting and securing the battery packs. Battery rack design must meet both strength requirements and consider assembly efficiency.

[0003] During the assembly of battery cells, such as battery packs, related technologies require that the cells be pushed into the battery rack assembly position and secured with fasteners to ensure stability. However, related technologies suffer from insufficient positioning accuracy, which can easily cause the battery cells to shift position, such as to the back, front, left, or right. This can prevent the battery cells from precisely aligning with the mounting holes on the battery rack, affecting both mounting and assembly efficiency.

[0004] Therefore, it is necessary to provide a battery rack and an energy storage container to at least partially solve the above problems. Summary of the Invention

[0127] In order to fully understand the embodiments of the present application, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the specific details familiar to those skilled in the art.

[0130] Terms like "center," "parallel," "perpendicular," "aligned," "symmetrical," etc., as used in this application do not necessarily require precision and may include typical engineering tolerances.

[0131] Hereinafter, specific embodiments of the present application will be described in more detail with reference to the accompanying drawings. These drawings illustrate representative embodiments of the present application and do not limit the present application.

[0132] During the assembly of battery cells, such as battery packs, related technologies require that the cells be pushed into the battery rack assembly position and secured with fasteners to ensure stability. However, related technologies suffer from insufficient positioning accuracy, which can easily cause the battery cells to shift position, such as to the back, front, left, or right. This can prevent the battery cells from precisely aligning with the mounting holes on the battery rack, affecting both mounting and assembly efficiency.

[0133] In order to at least solve the above technical problems, the present application provides a battery rack 160 and an energy storage container 100 having the battery rack 160. Figures 1 to 15 Elaborate in detail.

[0134] See Figures 5 to 9 An embodiment of the present application provides a battery rack 160 for installation in the energy storage compartment 110a of the energy storage container 100 to store battery cells in an assembled position. The battery rack 160 includes a rack body 161, a guide rail 162, a fixing member 163, a first stopper 164, and a second stopper 165. The dimension of the rack body 161 along the first horizontal direction D1 is greater than the dimension of the rack body 161 along the 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 includes 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 the two oppositely arranged battery cells in at least the first horizontal direction D1 and the second horizontal direction D2. The second limiting member 165 is located above the first supporting 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 supporting portion 162a in the vertical direction D3 to limit the battery cells in the vertical direction D3.

[0135] According to the battery rack 160 of the embodiment of the present application, when applied to the energy storage container 100, the rear end of the battery cell is limited in the first horizontal direction D1 and the second horizontal direction D2 by the first limiting member 164, and the battery cell is limited in the vertical direction D3 by the second limiting member 165, thereby achieving the positioning of the battery cell. Because the first limiting member 164 has two first limiting portions, it can simultaneously limit the rear ends of two relatively arranged battery cells. Compared to the technical solution in the related art that requires two limiting structures to limit the two battery cells in the first horizontal direction D1 respectively, the present application can reduce the number of components and simplify the structure of the battery rack 160, thereby reducing the space occupied by the positioning structure, thereby improving the compatibility of the battery rack 160 with battery cells of various sizes, and also helping to reduce the weight of the battery rack 160.

[0136] In some embodiments, the fixing member 163 includes a threaded hole. The 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 fixing member 163 through the external threads.

[0137] Of course, the first mounting portion can be detachably mounted to the fixing member 163 by other means besides threaded connection, such as snap connection.

[0138] By detachably mounting the first mounting portion to the fixing member 163 , it is convenient to remove and replace the first limiting member 164 according to maintenance or other needs.

[0139] In some other embodiments, the first mounting portion is fixed to the fixing member 163 by welding or other methods that are difficult to disassemble.

[0140] In some embodiments, the first mounting portion and the first limiting portion are integrally formed, which 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 portion may be fixed to the first limiting portion by welding or other methods.

[0142] See Figures 6 to 8 In some embodiments, the cross-sectional area of the first stopper, perpendicular to the first horizontal direction D1, decreases in a direction parallel to the first horizontal direction D1 and away from the mounting portion. During the movement of the battery cell box assembly, the first stopper provides a guiding function, facilitating easier connection between the first stopper and the positioning hole at the rear end of the battery cell. Furthermore, it helps to overcome errors in the installation position of the first stopper 164 itself and ensure reliable positioning of the battery cell.

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

[0144] In some embodiments, the fixing member 163 is a sheet metal member and is fixed between the first supporting portion 162a and the first connecting portion 162b by welding or other methods.

[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 the first horizontal direction D1. The two first guide portions 165b are connected to both 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 position of the battery cell in the vertical direction D3. During movement of the battery cell to the assembly position, one of the two first guide portions 165b, located near the end of the guide rail 162, guides the battery cell to gradually move below the second limiting portion 165a. Compared to a case without the first guide portion 165b, the battery cell can be more accurately and smoothly moved 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 portion 165a cooperates with the first support portion 162a to limit the battery cell in the vertical direction D3. During the process of disengaging the battery cell from the assembly position, the first guide portion 165b, one of the two first guide portions 165b located away from the end of the guide rail 162, is used to guide the battery cell gradually out of the second limiting portion 165a. Compared to a solution without the first guide portion 165b, the battery cell can be more accurately and smoothly disengaged from 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. Furthermore, when the first guide portion 165b is provided, the distance between the second limiting portion 165a and the first support portion 162a can be reduced compared to a solution without the first guide portion 165b. This can even allow the second limiting portion 165a to abut the battery cell in the assembly position, thereby further improving 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 rack body along the second horizontal direction D2. The guide rail 162 is provided with mounting holes. 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 rack 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 rack body of the battery rack 160.

[0148] See Figures 6 to 8 Optionally, the guide rail 162 further includes a bent flange formed on the upper portion 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, an intermediate 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 secured to the top side beams 113 of the energy storage container 100. The intermediate columns 161b extend along a vertical direction D3. The upper ends of the intermediate columns 161b are secured to the lower portion of the top crossbeam 161a. The lower ends of the intermediate columns 161b are adapted to be secured to the bottom longitudinal beams 123 of the energy storage container 100. The two sets of side columns 161c are located on either side of the intermediate column 161b along the first horizontal direction D1. The side columns 161c are parallel to the intermediate columns 161b. The upper ends of the side columns 161c are secured to the lower portion of the top crossbeam 161a. The lower ends of the side columns 161c are adapted to be secured 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 middle column 161b and the side column 161c are provided with threaded holes, and the guide rail 162 is connected to the threaded holes by bolts.

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

[0152] Optionally, multiple layers of supporting and positioning members 161d are provided on either side of the battery rack 160 along the second horizontal direction D2. The number of supporting and positioning members 161d in each layer is equal to the sum of the number of the middle columns 161b and the number of the 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 rack 160 also includes a first stopper 166a and a first locking member 166b. The first stopper 166a is detachably connected to the first fastening connection portion 162c. The first locking member 166b is movably connected to the first stopper 166a. The first locking member 166b is adapted to be detachably connected to the front end of the battery unit. After the battery unit is assembled to the assembly position of the guide rail 162, the first stopper 166a is bolted to the end of the guide rail 162 to prevent the battery unit from detaching from the guide rail 162 along the first horizontal direction D1. The battery unit is then fastened to the first stopper 166a by the first locking member 166b, thereby more reliably preventing the battery unit from moving.

[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 portion 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 as a whole along the first horizontal direction D1. The high-voltage box mounting member 167 includes two box limiting structures 167c arranged opposite to each other. The two box limiting structures 167c are arranged opposite to each other in the first horizontal direction D1. Each box limiting structure 167c is suitable for limiting a high-voltage box. Compared with the technical solution of arranging the high-voltage box mounting structure on the upper part of the battery rack 160 in the traditional technology, it can reduce the occupation of the upper space of the battery rack 160. When other structures such as the explosion-proof parts described below need to be arranged on the upper part of the energy storage container 100, it is beneficial to avoid the relevant structures.

[0155] See Figure 8Furthermore, the high-voltage box mounting member 167 includes a second supporting portion 167a and a second connecting portion 167b. The second supporting portion 167a extends along the first horizontal direction D1. The second supporting portion 167a is used to support the battery unit. The second connecting portion 167b is connected to one side of the second supporting portion 167a along the 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 supporting 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 smaller 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 portion 167 b is detachably connected to the frame body 161 by fastening members such as bolts.

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

[0158] Optionally, the high-voltage box mounting member 167 is a sheet metal member made by shearing and bending a metal plate.

[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 suitable for positioning the high-voltage box in the first horizontal direction D1. The fourth limiting portion 167d2 is connected to the upper portion 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 suitable for limiting the high-voltage box in the vertical direction D3. The second guide portion 167d3 is located on a side of the fourth limiting portion 167d2 facing away from 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 box-body 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 position along the second horizontal direction D2.

[0160] See Figure 5 、 Figure 6 as well as Figure 8 Optionally, a first weight-reducing notch 167b1 is defined in the second connecting portion 167b between the two box-body retaining structures 167c. A second weight-reducing notch 167b2 is defined in the second connecting portion 167b between the first retaining structure 167d and the second retaining structure 167e. The provision of the first and second weight-reducing notches 167b1, 167b2 reduces the weight of the high-voltage box mounting member 167.

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

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

[0163] In an embodiment not shown, the battery rack 160 further includes a second stopper, such as the first stopper 166a, and a second locking member, such as the first locking member 166b. The second stopper is bolted to the end of the second connecting portion 167b. The second locking member is movably connected to the second stopper for removable 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 and is suitable for fixing liquid cooling pipes.

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

[0166] According to the energy storage container 100 of the embodiment of the present application, by applying the above-mentioned battery rack 160, it is possible to reduce the number of components and simplify the structure of the battery rack 160 while accurately positioning the battery cells. This helps to reduce the space occupied by the first limiter 164, thereby improving the compatibility of the energy storage container 100 with battery cells of different sizes and reducing the weight of the energy storage container 100.

[0167] See Figures 1 to 5In some embodiments, the box body 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 frame body includes a top crossbeam 161a. The top crossbeam 161a extends along the width direction DW of the box body 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 is provided with 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 in the explosion-proof opening 111a. The explosion-proof support assembly 153 is fixed to the top crossbeam 161a at the explosion-proof opening 111a. The explosion-proof support assembly 153 is supported on the bottom of the explosion-proof component. The explosion-proof mounting assembly 154 is provided on the peripheral side of the explosion-proof opening 111a. The explosion-proof mounting assembly 154 is detachably connected to the explosion-proof component. The top crossbeam 161a is used to support the first top plate 111. The explosion-proof support assembly 153 is connected to the top crossbeam 161a, which can enhance the strength of the explosion-proof support assembly 153 in supporting the explosion-proof component. By providing the explosion-proof mounting assembly 154, it is possible to install the explosion-proof component on the top of the box body 110. Since 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 be damaged when the pressure in the energy storage cabin 110a exceeds the limit, thereby releasing pressure from the explosion-proof opening 111a.

[0168] See Figure 5 Furthermore, the energy storage container 100 also includes an explosion-proof connecting beam 152. The explosion-proof connecting beam 152 is located below the first top plate 111. A pair of explosion-proof connecting beams 152 is provided at each explosion-proof opening 111a. A pair of explosion-proof connecting beams 152 is located on both sides of the explosion-proof opening 111a along the width direction DW. The explosion-proof connecting beam 152 is connected to the adjacent top crossbeam 161a. The explosion-proof support assembly 153 is connected to the explosion-proof connecting beam 152. By connecting to the explosion-proof connecting beam 152 and the top crossbeam 161a, the explosion-proof support assembly 153 can further improve the load-bearing performance of the explosion-proof support assembly 153, so as to be compatible with the installation of explosion-proof parts 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 box body 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, the number of the first support beam 153a and the number of the second support beam 153b are each one. Thus, the explosion-proof support assembly 153 is constructed as a cross-shaped support frame composed of the first support beam 153a and the second support beam 153b. This can simplify the structure of the explosion-proof support assembly 153 while supporting the explosion-proof component.

[0171] It is understood that in other embodiments, the number of the first support beams 153a and the second support beams 153b may be 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 explosion-proof fasteners 154b. The explosion-proof mounting frame 154a is positioned around the explosion-proof opening 111a and secured 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 fasteners 154b are 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 box body 110 also includes an electrical control cabin 110b. The electrical control cabin 110b and the energy storage cabin 110a are arranged along the length direction DL of the box body 110. The box body 110 includes end walls 114 and a first end door 115. The end walls 114 and the first end door 115 are located at both ends of the box body 110 along the length direction DL. The first end door 115 is arranged corresponding to the electrical control cabin 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 cabin 110b. The first dehumidifier is fixed to the first end door 115 on a side that is adapted to face the electrical control cabin 110b. The first drain pipe 183 is arranged to extend 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 mounted to the end wall 114. The second drain pipe 184 is provided 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 providing the first and second dehumidifiers 182, it is possible to adjust the dryness and humidity of the electrical control cabin 110b and the energy storage cabin 110a. By providing the first and second drain pipes 183 and 184, it is possible to drain the water generated by the first and second dehumidifiers 182 due to dehumidification, so as to prevent electrical faults such as short circuits in the box or rust and other problems that affect the service life due to water dripping into the box.

[0174] See Figure 2 Furthermore, the housing 110 includes a threshold beam 131. The threshold beam 131 corresponds to the first end door 115. In the longitudinal direction DL of the housing 110, the other end of the first drain pipe 183 protrudes outside the threshold beam 131 when the first end door 115 is closed. This prevents water discharged from the first drain pipe 183 from dripping onto the threshold beam 131, thereby improving the waterproof performance of the first end door 115 and extending the service life of the threshold beam 131.

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

[0176] See Figure 1 Furthermore, the container 110 includes a bottom beam 132. The bottom 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 outside the bottom beam 132. This prevents water discharged from the second drain pipe 184 from dripping onto the bottom beam 132, thereby improving the waterproof performance of the energy storage container 100 and extending the service life of the bottom beam 132.

[0177] It can be understood that an openable and closable energy storage compartment door 118 is provided on the side of the box body 110 at a position corresponding to the energy storage compartment 110a.

[0178] See Figure 2 Optionally, a removable inspection door 119 is provided on the side of the housing 110, corresponding to the electrical control compartment 110b. This door is suitable for routine maintenance of the equipment within the electrical control compartment 110b. Compared to the first end door 115 with a lever lock 115a, the opening and closing of the inspection door 119 is more flexible and convenient. When installing or performing extensive maintenance on the electrical control equipment 181, the first end door 115 can be opened to perform the required operations.

[0179] See Figure 2 、 Figure 4 as well as Figure 9 In some embodiments, the housing 110 further includes a liquid cooling compartment 110c. The liquid cooling compartment 110c and the electric control compartment 110b are located on one side of the energy storage compartment 110a along the length direction DL of the housing 110. The liquid cooling compartment 110c and the electric control compartment 110b are arranged along the width direction DW. The housing 110 further includes a second end door 116 corresponding to the liquid cooling compartment 110c. The housing 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 provided on the second end door 116, and the second liquid cooling ventilation window 110d is located on the side of the liquid cooling compartment 110c facing away from the electric control compartment 110b. The second liquid cooling ventilation window 110d is arranged corresponding to the liquid cooling compartment 110c. The provision of the second end door 116 facilitates the installation of liquid cooling equipment and the repair and maintenance of the liquid cooling equipment. The first liquid cooling ventilator 116a and the second liquid cooling ventilator 110d are provided on the second end door 116, which facilitates ventilation and heat exchange of the liquid cooling device. The liquid cooling device is used to cool down each battery cell using liquid cooling.

[0180] See Figure 1 and Figure 2In some embodiments, the electrical control cabin 110b and the energy storage cabin 110a are arranged along the longitudinal direction DL of the housing 110. The housing 110 further 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 cabin 110a adjacent to the electrical control cabin 110b. The energy storage air outlet window 110e is located at the end of the energy storage cabin 110a away from the electrical control cabin 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 to discharge air. The energy storage air inlet window 110f is used to take in air. When the energy storage cabin 110a is cooled by air, cooler air enters the energy storage cabin 110a through the energy storage air inlet window 110f, and the air that has absorbed heat is discharged from the energy storage cabin 110a through the energy storage air outlet window 110e. By placing energy storage air inlet windows 110f and energy storage air outlet windows 110e at both ends of energy storage compartment 110a, with energy storage air outlet windows 110e higher than energy storage air inlet windows 110f, the heat exchange area between the air flow and the battery rack 160 and battery cells is increased, thereby improving heat exchange efficiency. The coolant in energy storage compartment 110a is toxic. The provision of energy storage air inlet windows 110f and energy storage air outlet windows 110e facilitates ventilation between energy storage compartment 110a and the exterior of housing 110, preventing the accumulation of coolant vapor within the compartment 110a.

[0181] See Figures 1 to 5 ,as well as Figure 9 In addition, the box body 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 box body 110 and extends along the width direction DW. The intermediate column 106 is fixed to the upper part of the door sill beam 131. The first end door 115 is provided between the corner column 101 and the intermediate column 106. The first partition wall 117a is separated from the end wall 114 and the first end door 115 respectively. The second partition wall 117b is connected between 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, and the second top plate 112 is a corrugated plate.

[0183] The energy storage container 100 in the related art has a flat floor structure, which is a weak part of the load-bearing performance 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 adapt to application requirements with higher loads.

[0184] See Figures 11 to 15According to an embodiment of the present application, the chassis 120 has a battery loading area 121 and an electrical loading area 122. The battery loading area 121 and the electrical loading area 122 are arranged along the length direction DL of the chassis 120. The battery loading area 121 is suitable for accommodating energy storage batteries. The electrical loading area 122 is suitable for accommodating at least electronic control equipment 181. The chassis 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 either side of the bottom longitudinal beam 123 along the width direction DW of the chassis 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 either side of the bottom longitudinal beam 123 along the width direction DW. The bottom cross beam 125 extends along the width direction DW. The ends of the bottom cross beam 125 are respectively connected to the bottom longitudinal beam 123 and the bottom side beams 124. Each group of bottom cross beams 125 includes a plurality of bottom cross beams 125. The plurality of bottom cross beams 125 are arranged at intervals along the length direction DL. Two groups of first floor panels 126 are located in the battery carrying area 121. The two groups of first floor panels 126 are located on both sides of the bottom longitudinal beam 123 along the width direction DW. Each group of first floor panels 126 includes a plurality of first floor panels 126. The 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 cross beam 125. In the height direction DH of the chassis 120, the end of the first floor panel 126 close to the bottom longitudinal beam 123 is higher than the end of the first floor panel 126 close to the bottom side beam 124. The first floor panel 126 includes a bent portion. The first floor panel 126 is lower than the top surface of the bottom cross beam 125 and the top surface of the bottom longitudinal beam 123. The first floor panel 126 , the bottom longitudinal beam 123 , the bottom cross beam 125 and the bottom side beam 124 enclose a receiving groove 127 .

[0185] According to the chassis 120 of the embodiment of the present application, by configuring the first floor panel 126 located in the battery loading area 121 so that "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," liquid can be directed toward the bottom side beam 124. This prevents liquid from accumulating in the middle portion of the chassis 120 along the width direction DW. Furthermore, the liquid can be collected by the receiving grooves 127 and isolated by the bottom cross beam 125 in each receiving groove 127 to prevent the liquid from flowing freely. This makes the distribution range of the liquid in the upper portion of the chassis 120 controllable, reducing the risk of water accumulation. Furthermore, by providing a bent portion in the first floor panel 126, the bending resistance of the first floor panel 126 can be enhanced. Compared to a flat floor panel, this improves the overall strength of the chassis 120, thereby improving the load-bearing capacity of the chassis 120 and adapting to applications requiring heavier loads. When the chassis 120 is applied to a container, the total weight of cargo or the total weight of structures such as equipment that can be loaded into the container can be increased.

[0186] See Figure 14 In some embodiments, the first floor panel 126 includes a first plate 126a and a second plate 126b connected in sequence along the width direction DW. The first plate 126a and the second plate 126b are arranged to intersect. 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 dripped 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 panel 126 to have a first plate body 126a and a second plate body 126b arranged in an intersecting manner, the overall contour of the first floor panel 126 is V-shaped or other shapes similar to the V-shape, thereby improving the structural strength of the first floor panel 126 while simplifying the structure of the first floor panel 126, thereby facilitating the processing and manufacturing of the first floor panel 126.

[0187] See Figures 11 to 14In addition, the base frame 120 also includes a floor drain assembly 140 and a connecting pipe 145. The floor drain assembly 140 is arranged at one end of the first floor 126 close to 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 longitudinal direction DL. The connecting pipe 145 is arranged corresponding to one end of the first floor 126 close to the bottom side beam 124. The connecting pipe 145 is connected to the adjacent receiving groove 127. The floor drain assembly 140 is used to discharge the liquid in the receiving groove 127 when it is opened, and to retain the liquid in the receiving groove 127 when it is closed. By providing the connecting pipe 145 to connect the adjacent receiving grooves 127, the liquid can flow through the connecting pipe 145 to the receiving groove 127 provided with the floor drain assembly 140, thereby eliminating the need to provide a floor drain assembly 140 in each receiving groove 127. Compared to the solution of installing a floor drain assembly 140 in each receiving groove 127, by providing a connecting pipe 145 and installing the floor drain assembly 140 in some of the receiving grooves 127, it is beneficial to reduce costs and simplify the operation when draining liquid. Furthermore, because the receiving grooves 127 are connected to each other through the connecting pipe 145, the liquid level in each receiving groove 127 can be kept consistent when the floor drain assembly 140 is in the closed state, thereby preventing electrical short circuits and other faults caused by excessive liquid levels in some receiving grooves 127, thereby improving electrical safety.

[0188] exist Figure 11 and Figure 12 In the illustrated example, the chassis 120 is equipped with two floor drain assemblies 140. These two floor drain assemblies 140 are located on either side of the bottom longitudinal beam 123. In the longitudinal direction DL, the floor drain assemblies 140 are positioned in the middle of the battery loading area 121. This reduces the number of floor drain assemblies 140 while also improving the efficiency of liquid collection from receiving slots 127 without floor drain assemblies 140 to receiving slots 127 with floor drain assemblies 140.

[0189] Optionally, the bottom cross beam 125 is provided with a mounting hole, and the connecting pipe 145 is passed through the mounting hole and welded to the bottom cross beam 125 .

[0190] See Figure 15Furthermore, the floor drain assembly 140 includes a liquid receiving part 141, a drain pipe 142 and a plug 143. A groove suitable for receiving liquid is formed on the upper part of the liquid receiving part 141. The groove is in the shape of a trumpet with a larger upper part and a smaller lower part. The upper part of the drain pipe 142 is connected to the liquid receiving part 141 and is connected to the receiving groove 127 through the liquid receiving part 141. The plug 143 is detachably connected to the lower end of the drain pipe 142 by a detachable connection such as a screw connection. When the plug 143 is connected to the drain pipe 142, the floor drain assembly 140 is in a closed state, which can prevent liquid from being discharged. When the plug 143 is detached from the drain pipe 142, the floor drain assembly 140 is in an open state, which can allow liquid to be discharged, thereby achieving the purpose of discharging liquid.

[0191] See Figure 11 and Figure 12 In an embodiment of the present application, the bottom longitudinal beam 123 includes a first longitudinal beam section 123a and a second longitudinal beam section 123b arranged in sequence along the length direction DL. The top surface of the first longitudinal beam section 123a is higher than the top surface of the second longitudinal beam section 123b. The first longitudinal beam section 123a is located in the battery carrying area 121. The second longitudinal beam section 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 cross beam 125. The bottom cross beam 125 is lower than the top surface of the first longitudinal beam section 123a. The top surface of the bottom cross beam 125 is flush with the top surface of the second longitudinal beam section 123b. The chassis 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 portion of the second longitudinal beam section 123b and the upper portion of the bottom cross beam 125. By setting the top surface of the second longitudinal beam section 123b corresponding to the electrical bearing area 122 to be flush with the top surface of the bottom cross beam 125, and setting the top surface of the first longitudinal beam section 123a corresponding to the battery bearing area 121 to be higher than the top surface of the bottom cross beam 125, on the one hand, the structural strength and bearing performance of the base frame 120 in the battery bearing area 121 can be improved, and on the other hand, the height of the second floor 128 can be lowered, so as to reserve more space in the height direction DH for equipment such as electrical control cabinets, thereby allowing the arrangement of equipment with larger height dimensions, thereby improving the compatibility of equipment selection.

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

[0193] See also Figure 11 and Figure 12Optionally, the electrical load-bearing area 122 is provided with two second floor panels 128 . These two second floor panels 128 are located on either side of the bottom longitudinal beam 123 along the width direction DW. The upper portion of one second floor panel 128 is used to house the liquid cooling equipment. The upper portion of the other second floor panel 128 is used to house the electrical control equipment 181. The second floor panel 128 for housing the electrical control equipment 181 has vias 128a defined therein. These vias 128a are used to route cables.

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

[0195] In addition, the base frame 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 longitudinal direction DL of the energy storage container 100. The clearance notch 124a is used to accommodate the corner post 101. The base frame 120 has mounting notches 120a at each of its four corners. The mounting notches 120a are used to mount the corner fittings 103. When the base frame 120 is attached to the energy storage container 100, a portion of the corner post 101 mounted to the clearance notch 124a is located in the clearance notch 124a, while the other portion corresponds to the mounting notch 120a. This allows the corner post 101 corresponding to the clearance notch 124a to be closer to the center of the energy storage container 100 relative to the corner fittings 103 along the longitudinal direction DL. This makes it easier to install the door hinge 102, preventing the door hinge 102 from protruding from the outside of 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 further includes a grounding member 133 disposed on the bottom side beam 124 .

[0197] The outer side of the rear corner post 101 of a related art energy storage container 100 typically protrudes from the outer side of the container's rear door panel and is flush with the outer side of the container's rear corner fitting 103. The container's 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. Specifically, the outer side of the outer corner post 101 protrudes from the outer side of the container's rear door panel. To seal the rear door panel, the outer corner post 101 must be recessed inward along the container's longitudinal direction DL until it is flush with the rear door panel. To securely connect the outer and inner corner posts 101, welding is typically required. This significantly reduces production efficiency and increases production costs, and is also prone to welding deformation.

[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 a reinforcing member 104. Equipment such as battery cells and a battery management system can be installed inside the energy storage container 100 as needed.

[0199] like Figure 1 、 Figure 2 as well as Figure 9 As shown, according to the energy storage container 100 of the present application, the cross-section of the corner post 101 of the energy storage container 100 is rectangular. Specifically, the cross-section of the corner post 101 can be square or rectangular. A door hinge 102 is provided on the first outer surface of the corner post 101. The first outer surface refers to a side surface 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. When closed, the first end door 115 is flush with the corner post 101. Specifically, the outer side surface of the first end door 115 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 the longitudinal direction DL.

[0200] Two corner pieces 103 are respectively arranged at the top and bottom ends of the corner post 101, and the outer side surfaces of the corner pieces 103 protrude from the first outer surface of the corner post 101 to a first distance along the length direction DL and form a step surface, so that the door hinge 102 does not extend beyond the corner pieces 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 corresponding corner pieces 103. The corner post 101 of the present application has a rectangular cross-section. Compared to existing corner posts 101 with L-shaped cross-sections, the corner post 101 of the present application is directly integrated, eliminating the need for welding, making welding deformation less likely and significantly reducing the production cost of the energy storage container 100. Furthermore, compared to existing corner posts 101 with L-shaped cross-sections, the corner post 101 of the present application has a rectangular cross-section. Replacing the L-shaped cross-section of the existing corner post 101 with the rectangular cross-section of the present application effectively improves the structural strength of the corner post 101.

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

[0203] like Figure 2 As shown, in some preferred embodiments of the present application, the corner post 101 for mounting the door hinge 102 protrudes from the connected corner piece 103 along the length direction DL toward the interior of the box. In this way, the structural strength of the corner post 101 can be effectively ensured.

[0204] like Figure 2 As shown, the reinforcing member 104 is provided 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 effectively enhance the connection strength between the corner post 101 and the corner piece 103.

[0205] like Figure 2 As shown, the top end of the reinforcing member 104 gradually tilts downward along the length direction DL, thereby forming an inclined surface at the top end of the reinforcing member 104. The inclined surface can make the reinforcing member 104 form a triangular shape as a whole, so that it has the stability of a triangle, thereby enabling the reinforcing member 104 to provide a better stable support function.

[0206] like Figure 2 As shown, the reinforcement member 104 further includes a vertical outer side surface, the bottom end of which is connected to the stepped surface, and the top end is connected to the inclined surface, and the vertical outer side surface does not protrude beyond the outer side surface of the corner piece 103. In this way, the vertical outer side surface is arranged perpendicular to the stepped surface and does not protrude beyond the outer side surface of the corner piece 103, thereby effectively preventing the vertical outer side surface of the reinforcement member 104 from interfering with its position 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 end of the bottom corner piece 103 .

[0208] like Figure 2 As shown, in some preferred embodiments of the present application, the reinforcement member 104 further includes welding notches. The openings of the welding notches face outward and are formed on both sides of the bottom end of the reinforcement member 104. By forming welding notches on both sides of the bottom end of the reinforcement member 104, the penetration depth of the weld between the reinforcement member 104 and the corner piece 103 can be increased, ensuring complete penetration of the weld, thereby achieving better welding quality. Furthermore, burn-through can be prevented. The design of the welding notches effectively prevents excessive concentration of heat generated during welding, thereby preventing the weld from penetrating the reinforcement member 104 and forming a hole.

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

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

[0211] In a specific embodiment of the present application, the reinforcing member 104 is in the shape of a trapezoid as a whole.

[0212] like Figure 2 As shown, the corner post 101 is integrally manufactured. This eliminates the need for welding, unlike conventional corner posts 101, which are typically welded together, such as an inner corner post 101 and an outer corner post 101. The corner post 101 used in this application is an integrally manufactured square tube, which eliminates welding deformation and effectively reduces costs.

[0213] like Figure 2 As shown, in some preferred embodiments of the present 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 the present application, one side of the energy storage container 100 has an opening (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 the present application further includes a seal, which is disposed around the first end door 115 and can provide a good sealing effect.

[0216] In a preferred embodiment of the present application, the sealing member may be made of rubber or silicone.

[0217] It should be noted that the sealing member 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 member.

[0218] It should also be noted that the corner post 101 and corner fitting 103 of the present application are staggered, so that when the first end door 115 is in the closed state, 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 via the door hinge 102, thereby preventing the first outer surface of the corner post 101 from being misaligned with the outer surface of the first end door 115 in the closed state along the longitudinal direction DL of the energy storage container 100 (i.e., the length direction DL). Furthermore, the need to construct a notch in the corner post 101 to provide installation space for the door hinge 102 adapted to connect to the first end door 115 is eliminated, thereby effectively preventing the structural strength of the corner post 101 from being reduced.

[0219] In related technologies, container cabling is primarily divided into two categories: low-voltage secondary power and communication cables, and high-voltage power cables. Due to limited space within containers, container cabling is often located on the bottom sides of the container, making it difficult to maintain. In the following description, low-voltage secondary power and communication cables are referred to as low-voltage cables, and high-voltage power cables are referred to as high-voltage cables.

[0220] See Figure 5 、 Figure 9 and Figure 10In the embodiment of the present application, the energy storage container 100 further includes a high- and low-voltage isolation assembly 170. The high- and low-voltage isolation assembly 170 is located below the high-voltage box mounting member 167. The high- and low-voltage isolation assembly 170 includes a first high- and low-voltage isolation member 171, a second high- and low-voltage isolation member 172, a third high- and low-voltage isolation member 173, and a high- and low-voltage collection member 176. The first high- and low-voltage isolation member 171 extends along the longitudinal direction DL of the energy storage container 100. The second high- and low-voltage isolation member 172 extends along the longitudinal direction DL of the energy storage container 100. The first and second high- and low-voltage isolation members 171 and 172 are disposed on either side of the bottom longitudinal beam 123. The first high- and low-voltage isolation member 171 is disposed corresponding to the electrical control cabin 110b. The high- and low-voltage collection member 176 is disposed at one end of the first high- and low-voltage isolation member 171 facing the electrical control cabin 110b and extends along the longitudinal direction DL of the energy storage container 100. The third high-low voltage isolation member 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 member 173 is connected to the second high-low voltage isolation member 172. The first high-low voltage isolation member 171, the second high-low voltage isolation member 172, and the third high-low voltage isolation member 173 each include a low-pressure circuit channel 170a and a high-pressure circuit channel 170b. The low-pressure circuit channel 170a of the first and second high-low voltage isolation members 171, 172 is located at one end of the first and second high-low voltage isolation members 171, 172 that is away from each other in the width direction DW. The low-pressure circuit channel 170a of the third high-low voltage isolation member 173 is located on the side of the third high-low voltage isolation member 173 that is closer to the electrical control cabin 110b along the length direction DL. The high-pressure circuit channel 170b of the first and second high-low voltage isolation members 171, 172 is connected through the high-pressure circuit channel 170b of the third high-low voltage isolation member 173. The high- and low-voltage collecting member 176 is connected to the first high- and low-voltage isolating member 171 and the third high- and low-voltage isolating member 173. The high- and low-voltage collecting member 176 includes a high-voltage line channel 170b and two low-voltage line channels 170a. Within the high- and low-voltage collecting member 176, the two low-voltage line channels 170a are located on either side of the high-voltage line channel 170b along the width direction DW. The high-voltage line channel 170b of the high- and low-voltage collecting member 176 communicates with the high-voltage line channel 170b of the first high- and low-voltage isolating member 171 and the high-voltage line channel 170b of the third high- and low-voltage isolating member 173. One low-voltage line channel 170a of the high- and low-voltage collecting member 176 communicates with the low-voltage line channel 170a of the first high- and low-voltage isolating member 171. The other low-voltage line channel 170a of the high- and low-voltage collecting member 176 communicates with the low-voltage line channel 170a of the third high- and low-voltage isolating member 173. The width of the low-voltage line channel 170 a is smaller than the width of the high-voltage line channel 170 b .The high-low voltage collecting member 176 is used to collect the high-voltage cables and low-voltage cables arranged in the first high-low voltage isolation member 171 and the second high-low voltage isolation member 172 and guide them to the electrical control cabin 110b. The third high-low voltage isolation member 173 is used to guide the high-voltage cables and low-voltage cables arranged in the second high-low voltage isolation member 172 to the high-low voltage collecting member 176.

[0221] See Figure 10 Furthermore, the first, second, and third high-low voltage isolation members 171, 172, and 173 have the same cross-sectional shape. Each of the first, second, and third high-low voltage isolation members 171, 172, and 173 includes an inner wall 174a, a first intermediate wall 174b, an outer wall 174c, and a first bottom wall 174d. The inner and outer walls 174a, 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 the inner and outer walls 174a, 174c, respectively. 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. A high-voltage line channel 170b is defined between the inner and outer walls 174a, 174b, and 174d. A low-voltage line passage 170a is formed between the first intermediate wall 174b, the outer wall 174c, and the first bottom wall 174d. A first high-voltage line opening 174b1 is defined in the first intermediate wall 174b. A second high-voltage line opening 174c1 and a low-voltage line opening 174c2 are defined in the outer wall 174c. The first high-voltage line opening 174b1 aligns with the second high-voltage line opening 174c1 to accommodate high-voltage lines. The low-voltage line opening 174c2 accommodates low-voltage lines. The first high-voltage line opening 174b1, the second high-voltage line opening 174c1, and the low-voltage line opening 174c2 are arranged corresponding 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 using the same metal plate. The first intermediate wall 174b is fixed to the first bottom wall 174d by welding or other means. The first intermediate wall 174b is made of a material capable of isolating electrical interference signals such as electromagnetic interference.

[0223] Continue reading Figure 10Similar to the first high-low voltage isolation member 171, the high-low voltage collection member 176 is additionally provided with 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 collection member 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 member 171. The second wall 175c corresponds to and is connected to the outer wall 174c of the third high-low voltage isolation member 173. A low-voltage line channel 170a is formed between one of the two second intermediate walls 175b and the first wall 175a and the second bottom wall 175d, for connecting the low-voltage line channel 170a of the first high-low voltage isolation member 171. Another low-pressure line channel 170 a is formed between the other of the two second intermediate walls 175 b and the second wall 175 c and the second bottom wall 175 d , for communicating with the low-pressure line channel 170 a 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 using the same metal plate. 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 electrical interference signals such as electromagnetic interference.

[0225] See also Figure 10 In addition, the high and low voltage isolation assembly 170 further includes a low voltage collecting member 176. The low voltage collecting member 176 is located on the side of the first high and low voltage isolation member 171 and the second high and low voltage isolation member 172 away from the electrical control cabin 110b. The low voltage collecting member 176 is connected to the first high and low voltage isolation member 171 and the second high and low voltage isolation member 172. The low voltage collecting member 176 forms a low voltage collecting channel 176a. The low voltage collecting channel 176a is connected to the low voltage line channel 170a of the first high and low voltage isolation member 171 and the low voltage line channel 170a of the second high and low voltage isolation member 172. By adding the low voltage collecting 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 cabin 110b.
