Description

Technical Field

[0001] The present application relates to the field of new energy vehicle technology, and in particular to a vehicle. Background Art

[0002] New energy batteries are being used more and more widely in life and industry. For example, new energy vehicles equipped with batteries have been widely used. In addition, batteries are also being increasingly used in energy storage fields.

[0003] In new energy vehicles equipped with batteries, these batteries can provide full or partial propulsion. In new energy vehicles, batteries can be mounted on the vehicle frame as part of the overall structure. However, if the battery surface facing the passenger compartment has a protrusion, it can create a significant gap between the battery and the frame, impacting the utilization of the battery storage space on the vehicle and, consequently, the battery capacity. Therefore, improving the utilization of battery storage space is a key research and development topic. Utility Model Content

[0004] The present application provides a vehicle that can effectively improve the utilization rate of the battery placement space on the vehicle, thereby effectively increasing the available space in the battery pack to increase the capacity of the battery.

[0005] This application is implemented through the following technical solutions.

[0006] A first aspect of an embodiment of the present application provides a vehicle, comprising: a vehicle frame, a battery, and a cover. The vehicle frame includes a passenger compartment; the battery includes a first box wall, the first box wall facing the passenger compartment along a first direction, and the first box wall has a first protrusion protruding toward the passenger compartment; a cover covers the floor of the passenger compartment along the first direction, the cover includes a main body and a relief portion, and when projected along the first direction on a projection plane perpendicular to the first direction, the relief portion covers at least a portion of the projection of the first protrusion, and the maximum dimension of the relief portion along the first direction is smaller than the maximum dimension of the main body along the first direction.

[0007] Since the covering member has a thinned or hollowed-out avoidance portion, the projection of the avoidance portion covers at least a portion of the projection of the first protrusion. In this way, the battery placement space of the vehicle can be utilized more effectively to increase the available space inside the battery. For example, when the first box wall is directly used as the passenger compartment floor, the covering member can be used to offset the height difference of the passenger compartment floor caused by the protrusion of the first box wall, thereby avoiding stepping discomfort to the user; alternatively, the first box wall is not directly used as the passenger compartment floor, and the passenger compartment floor is set separately, or the shape of the part of the passenger compartment floor corresponding to the first box wall can be set in accordance with the shape of the first box wall, so that the gap between the first box wall and the passenger compartment floor is set as small as possible to reduce the waste of battery placement space.

[0008] In some embodiments, the difference between the maximum dimension of the avoidance portion along the first direction and the maximum dimension of the main body portion along the first direction is a first dimension difference, and the difference between the maximum dimension of the first protrusion along the first direction and the first dimension difference is less than or equal to 10 mm.

[0009] Therefore, the size difference between the avoidance part and the main body is close to the protruding size of the first protrusion. The avoidance part can be better utilized to offset the unevenness of the passenger compartment floor caused by the first protrusion, reducing the discomfort caused to the user by stepping on it and improving the user experience.

[0010] In some embodiments, a difference between a maximum dimension of the first protrusion along the first direction and the first dimension difference is less than or equal to 5 mm.

[0011] In this way, the avoidance portion can be better utilized to offset the unevenness of the passenger compartment floor caused by the first protrusion, reducing the stepping discomfort caused to the user and improving the user experience.

[0012] In some embodiments, when projected along the first direction on a projection plane perpendicular to the first direction, the projection of the avoidance portion completely covers the projection of the first protruding portion.

[0013] Therefore, the avoidance portion can completely cover and accommodate the first protrusion, so that the height difference of all areas of the passenger compartment floor caused by the first protrusion can be at least partially offset by the size difference between the avoidance portion and the main body, so that the cover is relatively flat after covering the passenger compartment, reducing the stepping discomfort caused to the user and improving the user experience.

[0014] In some embodiments, the first box wall is configured as the floor of the passenger compartment, the avoidance portion includes a groove, and at least a portion of the first protrusion extends into the groove; or, the avoidance portion includes a through hole, and at least a portion of the first protrusion extends into the through hole.

[0015] In some embodiments where the first box wall directly serves as the passenger compartment floor, depending on the size of the first protrusion, the avoidance portion on the cover can be set as a groove formed by local thinning or a through hole formed by hollowing out, so that the size difference between the avoidance portion and the main body can better adapt to the protruding size of the first protrusion.

[0016] In some embodiments, the frame also includes a passenger compartment floor located at the bottom of the passenger compartment, the passenger compartment floor includes a second protrusion, the second protrusion forms a recess on the surface facing the first protrusion, at least a portion of the first protrusion extends into the recess, and when projected along the first direction on a projection plane perpendicular to the first direction, the projection of the avoidance portion covers at least a portion of the projection of the second protrusion.

[0017] In some embodiments where the passenger compartment floor is additionally configured, the passenger compartment floor can be configured to conform to the first box wall, allowing the first box wall to better fit the side of the passenger compartment floor facing away from the passenger compartment. The size difference between the relief portion and the main body is then used to match the size of the second protrusion, thereby offsetting the unevenness of the passenger compartment floor caused by the second protrusion. Depending on the size of the second protrusion, in some embodiments, the relief portion can be a groove formed by locally thinning the cover, while in other embodiments, the relief portion can be a through-hole formed by hollowing out the cover. This allows the size difference between the relief portion and the main body to better match the protruding size of the second protrusion, thereby improving the flatness of the passenger compartment floor and user experience while also increasing the utilization of the battery placement space.

[0018] In some embodiments, the difference between the maximum dimension of the avoidance portion along the first direction and the maximum dimension of the main body portion along the first direction is a first dimension difference, and the difference between the maximum dimension of the second protrusion along the first direction and the first dimension difference is less than or equal to 10 mm.

[0019] As a result, the size difference between the avoidance portion and the main body portion is close to the protruding size of the second protrusion. The setting of the cover can better offset the local height difference caused by the second protrusion on the passenger compartment floor, thereby improving user experience.

[0020] In some embodiments, the difference between the maximum dimension of the second protrusion along the first direction and the first dimension difference is less than or equal to 5 mm.

[0021] As a result, the size difference between the avoidance portion and the main body portion is further closer to the protruding size of the second protrusion. The setting of the cover can better offset the local height difference caused by the second protrusion on the passenger compartment floor, thereby improving user experience.

[0022] In some embodiments, when projected along the first direction on a projection plane perpendicular to the first direction, the projection of the avoidance portion completely covers the projection of the second protruding portion.

[0023] Therefore, the avoidance portion can completely cover and accommodate the second protrusion, so that the height difference of all areas of the passenger compartment floor caused by the second protrusion can be at least partially offset by the size difference between the avoidance portion and the main body, so that the cover is relatively flat after covering the passenger compartment, reducing the stepping discomfort caused to the user and improving the user experience.

[0024] In some embodiments, the avoidance portion includes a groove, and at least a portion of the second protrusion extends into the groove; or, the avoidance portion includes a through hole, and at least a portion of the second protrusion extends into the through hole.

[0025] Depending on the size of the second protrusion, the avoidance portion on the cover can be set as a groove formed by local thinning or a through hole formed by hollowing, so that the size difference between the avoidance portion and the main body can better adapt to the protruding size of the second protrusion.

[0026] In some embodiments, the first protrusions are configured in plurality, the avoidance portions are configured in plurality, and the plurality of avoidance portions are used to accommodate the plurality of first protrusions in a one-to-one correspondence along the first direction.

[0027] Therefore, when there are multiple first protrusions on the first box wall of the battery, the unevenness of the passenger compartment floor caused by the first protrusions can be at least partially offset by the setting of the covering part through the size difference setting of multiple avoidance parts and the main body part on the covering part and the corresponding setting of the avoidance parts to cover the first protrusions.

[0028] In some embodiments, the cover is configured as an elastic material.

[0029] Since the cover is configured with an elastic material, the rebound performance of the cover and the flatness of the floor of the passenger compartment can be further improved, which improves the user experience and is also conducive to processing and installation.

[0030] In some embodiments, the battery includes a accommodating cavity and a first component located in the accommodating cavity, the first protrusion is located on a side surface of the first box wall facing away from the accommodating cavity, and the first protrusion forms a accommodating groove along the first direction toward a side surface of the accommodating cavity, and at least a portion of the first component is located in the accommodating groove.

[0031] Since a receiving groove is formed on the side surface of the first protrusion toward the receiving cavity along the first direction, at least a portion of the first component is located in the receiving groove. Therefore, the internal receiving space of the battery with the first protrusion can be increased to accommodate more components, and this part of the space can be utilized to effectively increase the capacity of the battery.

[0032] In some embodiments, the first component includes at least one of a battery cell assembly, a busbar, and a sampling assembly.

[0033] Thus, the receiving groove can be used to accommodate at least a portion of the battery cell assembly. For example, when the battery cell assembly has a relatively regular main body and a protruding portion extending from the main body, at least a portion of the protruding portion can be located within the receiving groove, thereby facilitating the regular arrangement of the relatively regular main body within the battery, excluding the receiving groove. Alternatively, the receiving groove can be used to accommodate at least a portion of a manifold. The manifold is used to connect to the battery cell assembly and is typically located on the outer surface of the battery cell assembly. At least a portion of the manifold is located within the receiving groove, thereby allowing more space within the battery, excluding the receiving groove, to be used for accommodating the battery cell assembly, thereby facilitating efficient utilization of the battery space. Alternatively, the receiving groove can be used to accommodate at least a portion of a sampling assembly. The sampling assembly is used to connect to the battery cell assembly to collect status signals of the battery cell assembly and is typically located on the outer surface of the battery cell assembly. At least a portion of the sampling assembly is located within the receiving groove, thereby allowing more space within the battery, excluding the receiving groove, to be used for accommodating the battery cell assembly, thereby facilitating efficient utilization of the battery space. In this manner, the energy density and total energy of the battery can be improved.

[0034] In some embodiments, the first component includes a battery cell assembly, the battery cell assembly includes an electrode lead-out portion, and at least a portion of the electrode lead-out portion is located in the receiving groove.

[0035] Thus, the internal space of the battery can be reasonably utilized, so that the battery has a higher energy density. At the same time, the first protrusion plays a certain protective role on the electrode lead portion, effectively improving the structural stability of the electrode lead portion and the stability of the connection with the busbar.

[0036] In some embodiments, a portion of the same battery cell assembly is located within the receiving groove, and another portion is located outside the receiving groove.

[0037] Thus, the size of the first protrusion can be set smaller, so that the size of the first protrusion is more suitable for offsetting the thickness difference between the avoidance portion and the main body portion on the cover, which is beneficial to improving the flatness of the passenger compartment floor.

[0038] The embodiments of the present application include at least the following technical effects: being able to adjust the flatness of the passenger compartment floor, reducing the impact of the first protrusion of the battery on the flatness of the passenger compartment floor, improving the user's riding experience while also improving the utilization rate of the space inside the vehicle.

[0060] Below, this application is described in detail.

[0061] Currently, new energy batteries are increasingly being used in everyday life and industry. They are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric cars, as well as in a variety of fields such as aerospace. As the application of power batteries continues to expand, market demand is also growing.

[0062] The battery provides electrical energy to the vehicle and is installed under the passenger compartment as part of the vehicle structure. However, if the battery has a protrusion on the side facing the passenger compartment, this protrusion creates a large gap between the vehicle frame and the battery, wasting space on the vehicle and hindering battery capacity.

[0063] In addition, covering parts such as floor mats are usually provided in the passenger compartment of the vehicle to enhance the user's stepping experience.

[0064] After research and design, the first box wall of the battery can face the passenger compartment, and a first protrusion is provided on the first box wall. A cover can be provided in the passenger compartment, and the cover can cover the passenger compartment floor along the first direction. When the first box wall directly serves as the passenger compartment floor, or when the passenger compartment floor is set separately and is arranged in the shape of the first box wall, the cover can be provided with an avoidance portion. Compared with other areas, the avoidance portion can have a thinner thickness or a hollow setting. The avoidance portion can be arranged in the first direction corresponding to the first protrusion. In this way, the thickness difference between the avoidance portion and other areas can be utilized to offset the unevenness of the passenger compartment floor caused by the first protrusion, and while providing a better stepping experience for users without affecting the passenger compartment floor, the waste of battery placement space in the vehicle can be reduced and the energy density of the battery can be improved.

[0065] Based on such a design concept, the present application designs a vehicle, including a frame and a passenger compartment; a battery, including a first box wall, the first box wall facing the passenger compartment along a first direction, the first box wall having a first protrusion protruding toward the passenger compartment; a cover, covering the bottom wall of the passenger compartment along the first direction, the cover including a main body and an avoidance portion, projected along the first direction on a projection plane perpendicular to the first direction, the projection of the avoidance portion covers at least part of the projection of the first protrusion, and the maximum dimension of the avoidance portion along the first direction is smaller than the maximum dimension of the main body along the first direction.

[0066] Since the first box wall is formed with a first protrusion protruding toward the passenger compartment, the avoidance portion with a smaller size in the first direction can cover at least part of the first protrusion. In this way, it can offset at least part of the local height difference of the passenger compartment floor caused by the first protrusion of the first box wall, and at the same time improve the utilization rate of the battery placement space of the vehicle without affecting the flatness of the passenger compartment floor and user experience.

[0067] In the following embodiments, for the convenience of description, the electric device of one embodiment of the present application is taken as an example of a vehicle 1000. The following description is made with reference to the accompanying drawings.

The vehicle 1000 may be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended range vehicle. Figure 1 As shown, a battery 100 is installed inside vehicle 1000. Battery 100 can be located at the bottom, front, or rear of vehicle 1000. Battery 100 can be used to power vehicle 1000. For example, battery 100 can serve as an operating power source for vehicle 1000. Vehicle 1000 also includes a controller 200 and a motor 300. Controller 200 is used to control battery 100 to power motor 300, for example, to meet the power requirements of vehicle 1000 during startup, navigation, and driving.

[0069] In some embodiments of the present application, the battery 100 can serve not only as an operating power source for the vehicle 1000, but also as a driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0070] Figure 2 This is a three-dimensional exploded schematic diagram of the battery 100 provided in the embodiment of the present application. Figure 2 As shown, the battery 100 includes a box body 101 and at least one battery cell assembly 400 . The battery cell assembly 400 is accommodated in an accommodation cavity S formed inside the box body 101 . A first box wall 102 of the box body 101 has a first protrusion 103 .

[0071] In the embodiment of the present application, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0072] The battery cells can be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, etc., which are not limited in the embodiments of the present application.

[0073] Although not shown, a battery cell generally includes an electrode assembly. The electrode assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge process of the battery cell, active ions (such as lithium ions) are inserted and removed between the positive and negative electrodes. The separator is placed between the positive and negative electrodes to prevent short circuits between the positive and negative electrodes while allowing active ions to pass through.

[0074] In some embodiments, the electrode assembly is provided with tabs (not shown) that can conduct current from the electrode assembly. The tabs include a positive tab and a negative tab.

[0075] In some embodiments, a battery cell may include a housing. The housing is used to encapsulate components such as the electrode assembly and the electrolyte. The housing may be a steel housing, an aluminum housing, a plastic housing (e.g., polypropylene), a composite metal housing (e.g., a copper-aluminum composite housing), or an aluminum-plastic film.

[0076] As an example, the battery cell can be a cylindrical battery cell, a prismatic battery cell, a soft-pack battery cell or a battery cell of other shapes.

The shell may have one or more openings. One or more end caps may also be provided.

[0078] In some embodiments, the housing can be a sealed structure or a non-sealed structure. For example, in a non-sealed structure, the housing protects the electrode assembly and includes a sealing bag between the housing and the electrode assembly, which encapsulates the electrode assembly and electrolyte. Specifically, the sealing bag can be a bag-shaped insulating member or an aluminum-plastic film.

[0079] In some embodiments, the housing is provided with at least one electrode lead, which is electrically connected to a tab (not shown).

A battery cell assembly (Battery Cell Assembly) may include multiple battery cells, which are connected in series, parallel, or hybrid via a busbar. In some embodiments, a battery cell assembly may also be a single battery cell.

[0082] In some embodiments, a battery cell assembly may be formed by arranging multiple battery cells. For example, the battery cell assembly may be a battery module, which is formed by arranging and securing multiple battery cells to form a single module. For example, a battery module may be formed by bundling multiple battery cells using cable ties.

[0083] In some embodiments, the battery device may be a battery pack, which includes a case and one or more battery cell assemblies, wherein the battery cell assemblies are housed in the case.

[0084] As an example, the battery cell assembly may be a battery module, and the battery cell assembly may be accommodated in the box by fixing the battery module in the box.

[0085] As an example, the battery cell assembly may also be housed in the box by directly fixing the plurality of battery cells to the box.

[0086] As an example, the housing may include a first housing and a second housing. The first housing and the second housing engage to form an enclosed space within the housing to house the battery cell assembly. Enclosed here means covered or closed, and can be either sealed or unsealed. The first housing may be a top cover or a bottom plate.

[0087] As an example, the box may include a top cover, a frame, and a bottom plate, wherein the top cover and the bottom plate are respectively connected to the frame to form a closed space inside the box to accommodate the battery cell assembly.

[0088] As an example, the box body can be used as a part of the chassis structure of the vehicle. For example, the top cover of the box body can become at least a part of the floor of the vehicle, or the frame of the box body can become at least a part of the crossbeam and longitudinal beam of the vehicle.

[0091] Below, refer to Figures 3 to 11 Some embodiments of the present application are described in detail.

Figure 8 Schematic diagram of a three-dimensional explosion of batteries and covers provided in other embodiments of the present application; Figure 9 for Figure 8 Bottom view of the middle cover. Figure 10 A partial cross-sectional view of a battery provided for some embodiments of the present application. Figure 11 A partial cross-sectional view of a battery installation location in a vehicle is provided for further embodiments of the present application.

[0094] In some embodiments of the present application, for the convenience of explanation, Figures 2 to 11 As shown by the arrows in FIG, the direction indicated by arrow X is the vehicle's travel direction, the direction indicated by arrow Y is the vehicle's left-right direction, and the direction indicated by arrow Z is the vehicle's up-down direction. In a specific embodiment, the first direction may be the vehicle's up-down direction. The direction indicated by arrow Z is sometimes referred to as "upward," and the opposite direction is referred to as "downward."

[0095] A first aspect of an embodiment of the present application provides a vehicle, such as Figure 3In the example shown, the vehicle includes: a vehicle frame 1002, a battery 100, and a cover 104. The vehicle frame 1002 includes a passenger compartment 1004; the battery 100 includes a first box wall 102, the first box wall 102 facing the passenger compartment 1004 along a first direction, and the first box wall has a first protrusion 103 protruding toward the passenger compartment 1004; the cover 104 covers the floor of the passenger compartment 1004 along a first direction (Z), and the cover 104 includes a main body 106 and a relief portion 105. When projected along the first direction (Z) on a projection plane perpendicular to the first direction (Z), the projection of the relief portion 105 covers at least part of the projection of the first protrusion 103, and the maximum dimension H2 of the relief portion 105 along the first direction (Z) is smaller than the maximum dimension H1 of the main body 106 along the first direction (Z).

[0096] It should be noted that, for the sake of convenience, Figure 3 The structure in which the first box wall 102 serves as the passenger compartment floor 1003 is shown. In other embodiments of the present application, the passenger compartment floor 1003 may be additionally provided and located between the first box wall 102 and the cover 104 .

[0097] For example, when the first box wall 102 directly serves as the passenger compartment floor 1003, the cover 104 can be used to offset the height difference of the passenger compartment floor 1003 caused by the protrusion of the first box wall 102, thereby avoiding causing discomfort to the user.

[0098] As another example, the first box wall 102 does not directly serve as the passenger compartment floor 1003, and the passenger compartment floor 1003 is set separately. The shape of the part of the passenger compartment floor 1003 corresponding to the first box wall 102 can also be set in the shape of the first box wall 102, so that the gap between the first box wall 102 and the passenger compartment floor 1003 is set as small as possible to reduce the waste of battery placement space.

[0099] For example, Figure 2 As shown, the battery 100 has a first box wall 102 , and the first box wall 102 is formed with a first protrusion 103 . The first protrusion 103 bulges from the first box wall 102 toward a side facing away from the accommodating chamber S.

[0100] Optionally, the number of the first protrusions 103 may be one or more, which is not limited in this application.

[0101] Optionally, when viewed along the first direction (Z), the shape of the first protrusion 103 may be circular, elliptical, triangular, square or other polygonal. The first protrusion 103 may also be an irregular shape, which is not limited in this application.

[0102] Alternatively, along the first direction (Z), a single first protrusion 103 may have a plurality of different heights. Alternatively, when the first box wall 102 forms a plurality of first protrusions 103, along the first direction (Z), the heights of the plurality of first protrusions 103 may be consistent or inconsistent.

[0103] Optionally, the first protrusions 103 may be regularly arranged to form a circle, ellipse, triangle, quadrilateral or other polygon, or may be arranged in an array, such as spaced apart along the X direction or the Y direction.

[0104] For example, Figure 3 As shown, the battery 100 may be disposed at the bottom of the vehicle 1000 , with the first box wall 102 facing the passenger compartment 1004 along a first direction (Z), and the first protrusion 103 protruding toward the passenger compartment 1004 .

[0105] Optionally, the battery 100 may be directly mounted on the bottom of the vehicle 1000 or may be mounted on the bottom of the vehicle 1000 via a connector such as a tray, which is not limited in this application.

[0106] For example, the first box wall 102 may be a box wall of the box body 101 that is close to the passenger compartment 1004 in the first direction (Z).

[0107] Optionally, the cover 104 can be placed directly on the floor of the passenger compartment 1004, or it can be fixed to the floor of the passenger compartment 1004 by means of threaded connection, bonding, etc. The connection between the two can be a fixed connection or a detachable connection.

[0108] The covering member 104 covering the floor of the passenger compartment 1004 means that a projection of the covering member 104 in the first direction (Z) at least partially overlaps with a projection of the floor of the passenger compartment 1004 in the first direction (Z).

[0109] In a specific embodiment, Figure 4 、 Figure 5 、 Figure 6 As shown, the cover 104 includes a main body 106 and a relief portion 105. When projected along the first direction (Z) on a projection plane perpendicular to the first direction (Z), the projection of the relief portion 105 covers at least part of the projection of the first protruding portion 103. Figure 7 As shown, the maximum dimension H2 of the avoidance portion 105 along the first direction (Z) is smaller than the maximum dimension H1 of the main body portion 106 along the first direction (Z).

[0110] Optionally, the number of the avoidance portion 105 may be one or more.

[0111] Optionally, the number of the first protrusions 103 may be the same as the number of the avoidance portions 105 , or a plurality of first protrusions 103 may be accommodated in one avoidance portion 105 , which is not limited in the present application.

[0112] Optionally, when viewed along the first direction (Z), the avoidance portion 105 may be in a circular, elliptical, triangular, square or other polygonal shape, or in an irregular shape, which is not limited in the present application.

[0113] Alternatively, as Figure 7 As shown, along the first direction (Z), a single avoidance portion 105 can have multiple different sizes. Alternatively, when the cover 104 is provided with multiple avoidance portions 105, along the first direction (Z), the sizes of the multiple avoidance portions 105 can be consistent or inconsistent.

[0114] Optionally, the side of the cover 104 facing the passenger compartment 1004 may be a flat surface or a concave-convex surface with higher flatness formed after covering.

[0115] Illustratively, along the first direction (Z), the body portion 106 has the same size.

[0116] For example, Figure 7 As shown, the cover 104 is layered, and a single relief portion 105 can have multiple different sizes (thicknesses) within it, while the main body 106 has the same size (thickness). Along the first direction (Z), the maximum size of the relief portion 105 is H2, while the maximum size of the main body 106 is H1. H2 is smaller than H1.

[0117] Optionally, the avoidance portions 105 may be regularly arranged to form a circle, ellipse, triangle, quadrilateral or other polygon, or may be arranged in an array, such as spaced apart along the X direction or the Y direction.

[0118] Optionally, at least one in-vehicle seat 1001 may be provided in the passenger compartment 1004 .

[0119] Since the cover 104 has a relief portion 105 having a thickness dimension smaller than that of the main body 106 , the projection of the relief portion 105 covers at least a portion of the projection of the first protrusion 103 . In this way, the battery placement space of the vehicle 1000 can be more effectively utilized, and the available space inside the battery 100 is increased to improve the capacity of the battery 100 .

[0120] In the embodiments of the present application, Figure 2 、 Figure 10As shown, the battery 100 includes a accommodating cavity S and a first component 110 located in the accommodating cavity S. The first protrusion 103 is located on a side surface of the first box wall 102 facing away from the accommodating cavity S, and the first protrusion 103 is formed with an accommodating groove 107 along a first direction (Z) toward a side surface of the accommodating cavity S. At least a portion of the first component 110 is located in the accommodating groove 107.

[0121] Optionally, the shape of the receiving groove 107 can be regular or irregular, continuous or discontinuous, and this application does not impose any limitation on this.

[0122] Alternatively, the first component 110 may be a battery cell assembly 400 , a battery cell, a busbar 111 , a sampling assembly 112 , a wiring harness, a battery management assembly, or the like.

[0123] Optionally, the first component 110 may be a busbar 111 , a wiring harness, etc., and is completely located in the receiving groove 107 .

[0124] Alternatively, the first component 110 may be a battery cell assembly 400 , and a portion of the battery cell assembly 400 is located in the receiving groove 107 .

[0125] Since the first protrusion 103 has a receiving groove 107 formed on one side surface thereof along the first direction (Z) toward the receiving cavity S, at least a portion of the first component 110 is located in the receiving groove 107. Therefore, the internal receiving space of the battery 100 having the first protrusion 103 can be increased to accommodate more components, and this space can be utilized to effectively increase the capacity of the battery 100.

[0126] In the embodiment of the present application, the first component 110 includes at least one of a battery cell assembly 400 , a current bus 111 , and a sampling assembly 112 .

[0127] In a specific embodiment, Figure 10 As shown, the first component 110 includes a battery cell assembly 400, a current collector 111, and a sampling assembly 112. The first component 110 is partially received in the receiving groove 107. The present application does not limit the positional relationship between the battery cell assembly 400, the current collector 111, and the sampling assembly 112.

[0128] Optionally, the accommodating groove 107 accommodates at least a portion of the battery cell assembly 400. For example, when the battery cell assembly 400 has a relatively regular main body and a protruding portion protruding from the main body, at least a portion of the protruding portion can be located in the accommodating groove 107, which is conducive to the regular arrangement of the relatively regular overall part in the space outside the accommodating groove 107 in the battery 100.

[0129] Optionally, the receiving groove 107 can be used to accommodate at least a portion of the busbar 111. The busbar 111 can be used to connect the battery cell assembly 400 and is usually arranged on the outer surface of the battery cell assembly 400. At least a portion of the busbar 111 is arranged in the receiving groove 107, so that more space in the battery 100 other than the receiving groove 107 can be used to accommodate the battery cell assembly 400, which is conducive to improving the effective utilization of the space in the battery.

[0130] Alternatively, the receiving groove 107 can be used to accommodate at least a portion of the sampling component 112. The sampling component 112 is used to connect to the battery cell assembly 400 to collect the status signal of the battery cell assembly 400 and is usually arranged on the outer surface of the battery cell assembly 400. At least a portion of the sampling component 112 is arranged in the receiving groove 107, so that more space in the battery 100 other than the receiving groove 107 can be used to accommodate the battery cell assembly 400, which is conducive to improving the effective use of the space in the battery.

[0131] The busbar 111 can connect the battery cell assemblies 400 to achieve electrical connection between the battery cells; for example, parallel connection, series connection, or mixed connection. The busbar 111 can be in the shape of a cuboid or a cube. This application does not limit the connection method and size of the busbar 111.

[0132] The sampling assembly 112 can receive signals such as current, voltage, and temperature transmitted by the battery cell assembly 400. The sampling assembly 112 can be directly connected to the battery cell assembly 400 or connected to the battery cell assembly 400 via a busbar 111 or other connector to collect signals from the battery cell assembly 400. This application does not limit this.

[0133] This is beneficial to improving the effective utilization of the space within the battery, thereby improving the energy density and total energy of the battery 100.

[0134] In a specific embodiment, Figure 10 As shown, the first component 110 includes a battery cell assembly 400 , and the battery cell assembly 400 includes an electrode lead-out portion 401 . At least a portion of the electrode lead-out portion 401 is located in the receiving groove 107 .

[0135] The electrode lead-out portion 401 can input or output the electrical energy of the battery cell. This application does not limit the shape and number of the electrode lead-out portion 401.

[0136] Thus, the internal space of the battery 100 can be reasonably utilized, resulting in a higher energy density of the battery 100. At the same time, the first protrusion 103 provides a certain degree of protection for the electrode lead portion 401, effectively improving the structural stability of the electrode lead portion 401 and the stability of its connection with the busbar 111.

[0137] In a specific embodiment, Figure 10 As shown, a portion of the same battery cell assembly 400 is located in the receiving groove 107 , and another portion is located outside the receiving groove 107 .

[0138] Therefore, the size of the first protrusion 103 can be set smaller, so that the size of the first protrusion 103 is more suitable for offsetting the thickness difference between the avoidance portion 105 and the main body 106 on the cover 104, which is beneficial to improving the flatness of the passenger compartment floor 1003.

[0139] In an embodiment of the present application, the difference between the maximum dimension H2 of the avoidance portion 105 along the first direction (Z) and the maximum dimension H1 of the main body portion 106 along the first direction (Z) is the first dimension difference H, and the difference between the maximum dimension H3 of the first protrusion 103 along the first direction (Z) and the first dimension difference H is less than or equal to 10 mm.

[0140] For example, Figure 7 、 Figure 10 As shown, when projected along the first direction (Z) on a projection plane perpendicular to the first direction (Z), the projection of the relief portion 105 covers at least a portion of the projection of the first protrusion 103. Along the first direction (Z), the maximum dimension H3 of the first protrusion 103 is no greater than the first dimension difference H. This allows the projection of the relief portion 105 to offset the unevenness of the passenger compartment floor 1003 caused by the first protrusion 103, thereby reducing any discomfort experienced by the user.

[0141] For example, the difference between the maximum dimension H3 of the first protrusion 103 along the first direction (Z) and the first dimension difference H can be 0 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. The difference between the maximum dimension H3 of the first protrusion 103 along the first direction (Z) and the first dimension difference H can take into account both the accommodation effect of the first protrusion 103 and the overall size of the floor of the passenger compartment 1004, effectively improving the utilization of the battery placement space on the vehicle 1000.

[0142] Therefore, the size difference between the avoidance portion 105 and the main body portion 106 is close to the protruding size of the first protrusion 103. The avoidance portion 105 can be better utilized to offset the unevenness of the passenger compartment floor 1003 caused by the first protrusion 103, reducing the stepping discomfort caused to the user and improving the user experience.

[0143] In the embodiment of the present application, the difference between the maximum dimension of the first protrusion 103 along the first direction (Z) and the first dimension difference is less than or equal to 5 mm.

[0144] Exemplarily, the difference between the maximum dimension H3 of the first protrusion 103 along the first direction (Z) and the first dimension difference H can be 0mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm or 5mm, etc.

[0145] In this way, the avoidance portion 105 can be better utilized to offset the unevenness of the passenger compartment floor 1003 caused by the first protrusion 103, thereby reducing the stepping discomfort caused to the user and improving the user experience.

[0146] In the embodiment of the present application, when projected along the first direction (Z) on a projection plane perpendicular to the first direction (Z), the projection of the avoiding portion 105 completely covers the projection of the first protruding portion 103 .

[0147] In the embodiments of the present application, Figure 4 、 Figure 5 As shown, the first protruding portion 103 is extended along the traveling direction (X) of the vehicle 1000 , and the avoiding portion 105 is extended along the traveling direction (X) of the vehicle 1000 .

[0148] Optionally, the number of the first protrusions 103 may be one or more, and the plurality of first protrusions 103 extending along the traveling direction (X) of the vehicle 1000 may be arranged at equal intervals or at unequal intervals.

[0149] Optionally, there may be one or more avoidance portions 105, and the plurality of avoidance portions 105 extending along the travel direction (X) of the vehicle 1000 may be arranged at equal or unequal intervals. Optionally, one avoidance portion 105 may accommodate one or more first protrusions 103, with the projection of the avoidance portion 105 being able to completely cover the projection of the first protrusion 103.

[0150] Optionally, the length of the first protrusion 103 extending along the traveling direction (X) of the vehicle 1000 can be equal to the length of the box body 101 along the traveling direction (X) of the vehicle 1000, or can be less than the length of the box body 101 along the traveling direction (X) of the vehicle 1000.

[0151] Optionally, the length of the avoidance portion 105 extending along the traveling direction (X) of the vehicle 1000 may be equal to the length of the cover 104 along the traveling direction (X) of the vehicle 1000 , or may be less than the length of the cover 104 along the traveling direction (X) of the vehicle 1000 .

[0152] Optionally, the length of the first protrusion 103 extending along the traveling direction (X) of the vehicle 1000 may be equal to the length of the avoidance portion 105 extending along the traveling direction (X) of the vehicle 1000, or may be less than the length of the avoidance portion 105 extending along the traveling direction (X) of the vehicle 1000.

[0153] In a specific embodiment, the first protrusion 103 extends along the travel direction (X) of the vehicle 1000, and the avoidance portion 105 extends in the same direction as the first protrusion 103. This allows the avoidance portion 105 to better adapt to the shape of the first protrusion 103 and more easily accommodate the first protrusion 103. The battery 100 can be arranged along the travel direction of the vehicle 1000 based on its own length and width dimensions and the length and width dimensions of the floor of the passenger compartment 1004, thereby increasing the flexibility of the battery 100 configuration.

[0154] In the embodiments of the present application, Figure 8 、 Figure 9 As shown, the first protruding portion 103 is extended along the left-right direction (Y) of the vehicle 1000 , and the avoiding portion 105 is extended along the left-right direction of the vehicle 1000 .

[0155] Optionally, the number of the first protrusions 103 may be one or more, and the plurality of first protrusions 103 extending along the left-right direction (Y) of the vehicle 1000 may be arranged at equal intervals or at unequal intervals.

[0156] Optionally, the number of avoidance portions 105 may be one or more, and the multiple avoidance portions 105 extending along the left-right direction (Y) of the vehicle 1000 may be arranged at equal or unequal intervals. Optionally, one avoidance portion 105 may accommodate one or more protrusions, and the projection of the avoidance portion 105 may completely cover the projection of the first protrusion 103.

[0157] Optionally, the length of the first protrusion 103 extending along the left-right direction (Y) of the vehicle 1000 can be equal to the length of the box body 101 along the left-right direction (Y) of the vehicle 1000, or it can be less than the length of the box body 101 along the left-right direction (Y) of the vehicle 1000.

[0158] Optionally, the length of the avoidance portion 105 extending along the left-right direction (Y) of the vehicle 1000 can be equal to the length of the cover 104 along the left-right direction (Y) of the vehicle 1000, or it can be less than the length of the cover 104 along the left-right direction (Y) of the vehicle 1000.

[0159] Optionally, the length of the first protrusion 103 extending along the left-right direction (Y) of the vehicle 1000 may be equal to the length of the avoidance portion 105 extending along the left-right direction (Y) of the vehicle 1000, or may be less than the length of the avoidance portion 105 extending along the left-right direction (Y) of the vehicle 1000.

[0160] In a specific embodiment, Figure 8 、 Figure 9 As shown, the first protrusion 103 extends along the left-right direction (Y) of the vehicle 1000, and the avoidance portion 105 extends in the same direction as the first protrusion 103, so that the avoidance portion 105 better adapts to the shape of the first protrusion 103 and can more easily accommodate the first protrusion 103.

[0161] Therefore, the avoidance portion 105 can completely cover and accommodate the first protrusion 103, so that the height difference of all areas of the passenger compartment floor 1003 caused by the first protrusion 103 can be at least partially offset by the size difference between the avoidance portion 105 and the main body 106, so that the cover 104 is relatively flat after covering the floor of the passenger compartment 1004, reducing the stepping discomfort caused to the user and improving the user experience.

[0162] In the embodiments of the present application, Figure 3 As shown, the first box wall 102 is configured as the floor of the passenger compartment 1004, the avoidance portion 105 includes a groove, and at least a portion of the first protrusion 103 extends into the groove; or, the avoidance portion 105 includes a through hole, and at least a portion of the first protrusion 103 extends into the through hole.

[0163] Optionally, the first box wall 102 may be a partial floor of the passenger compartment 1004 , or may serve as the entire floor of the passenger compartment 1004 .

[0164] Optionally, the avoidance portion 105 may be a groove formed by local thinning or a through hole formed by hollowing. The shapes illustrated in the drawings of this application are only for illustration of the through hole and the groove, and are not limiting.

[0165] For example, the groove may be formed by partially thinning the cover 104 .

[0166] For example, the through hole may be formed by partially hollowing out the cover 104 .

[0167] Optionally, the avoidance portion 105 may have rounded corners or chamfered corners, which is not limited in this application.

[0168] Optionally, the first protrusion 103 may partially extend into the avoidance portion 105 , or may completely extend into the avoidance portion 105 .

[0169] In some embodiments where the first box wall 102 directly serves as the passenger compartment floor 1003, depending on the size of the first protrusion 103, the avoidance portion 105 on the cover 104 can be set as a groove formed by local thinning or a through hole formed by hollowing out, so that the size difference between the avoidance portion 105 and the main body 106 can better adapt to the protruding size of the first protrusion 103.

[0170] In the embodiments of the present application, Figure 11 As shown, the vehicle frame 1002 also includes a passenger compartment floor 1003 located at the bottom of the passenger compartment 1004, and the passenger compartment floor 1003 includes a second protrusion 108, and the second protrusion 108 forms a recess 109 on the surface facing the first protrusion 103, and at least a portion of the first protrusion 103 extends into the recess 109. When projected along the first direction (Z) on a projection plane perpendicular to the first direction (Z), the projection of the avoidance portion 105 covers at least a portion of the projection of the second protrusion 108.

[0171] Optionally, the number of the second protrusions 108 of the passenger compartment floor 1003 may be one or more, which is not limited in this application.

[0172] Optionally, when viewed along the first direction (Z), the shape of the projection of the second protrusion 108 may be circular, elliptical, triangular, square or other polygonal. The shape of the projection of the second protrusion 108 may also be an irregular shape, which is not limited in this application.

[0173] Alternatively, a single second protrusion 108 may have multiple different heights along the first direction (Z). Alternatively, when multiple second protrusions 108 are formed on the passenger compartment floor 1003 , the heights of the multiple second protrusions 108 along the first direction (Z) may be uniform or non-uniform.

[0174] Optionally, the second protrusions 108 may be regularly arranged to form a circle, ellipse, triangle, quadrilateral or other polygon, or may be arranged in an array, such as spaced apart along the X direction or the Y direction.

[0175] Optionally, the second protruding portion 108 may be completely accommodated in the avoiding portion 105 , or may be partially accommodated in the avoiding portion 105 .

[0176] Optionally, the number of the second protrusions 108 may be the same as the number of the avoidance portions 105 , or a plurality of second protrusions 108 may be accommodated in one avoidance portion 105 , which is not limited in the present application.

[0177] Optionally, when viewed along the first direction (Z), the projected shape of the recess 109 may be circular, elliptical, triangular, square or other polygonal. The projected shape of the recess 109 may also be an irregular shape, which is not limited in this application.

[0178] Alternatively, along the first direction (Z), a single recess 109 may have multiple different depths. Alternatively, when the passenger compartment floor 1003 is provided with multiple recesses 109, the depths of the multiple recesses 109 along the first direction (Z) may be uniform or inconsistent.

[0179] Optionally, the recesses 109 may be regularly arranged to form a circle, ellipse, triangle, quadrilateral or other polygon, or may be arranged in an array, such as spaced apart along the X direction or the Y direction.

[0180] Optionally, the number of the recess 109 may be one or more.

[0181] Optionally, the number of the first protrusions 103 may be the same as the number of the recesses 109 , or a plurality of first protrusions 103 may be accommodated in one recess 109 , which is not limited in the present application.

[0182] In some embodiments where the passenger compartment floor 1003 is configured separately, the passenger compartment floor 1003 can be configured to conform to the first compartment wall 102, allowing the first compartment wall 102 to better align with the side of the passenger compartment floor 1003 facing away from the passenger compartment 1004. The size difference between the relief portion 105 and the main body 106 is then used to match the size of the second protrusion 108, thereby offsetting the unevenness of the passenger compartment 1004 floor caused by the second protrusion 108. Depending on the size of the second protrusion 108, in some embodiments, the relief portion 105 can be a groove formed by partially thinning the cover 104. In other embodiments, the relief portion 105 can be a through-hole formed by partially hollowing out the cover 104. This allows the size difference between the relief portion 105 and the main body 106 to better match the protrusion size of the second protrusion 108, improving the flatness of the floor on the passenger compartment 1004 side and user experience while also increasing the utilization of the battery storage space. In an embodiment of the present application, the difference between the maximum dimension H2 of the avoidance portion 105 along the first direction (Z) and the maximum dimension H1 of the main body portion 106 along the first direction (Z) is the first dimension difference H, and the difference between the maximum dimension H4 of the second protrusion 108 along the first direction (Z) and the first dimension difference H is less than or equal to 10 mm.

[0183] Along the first direction (Z), the maximum dimension H3 of the second protrusion 108 is not greater than the first dimension difference H, so that the avoidance portion 105 in the projected covered part can offset the height difference of the entire area of the passenger compartment floor 1003 caused by the second protrusion 108, thereby improving the flatness.

[0184] For example, the difference between the maximum dimension H4 of the second protrusion 108 along the first direction (Z) and the first dimension difference H can be 0 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. The difference between the maximum dimension H4 of the second protrusion 108 along the first direction (Z) and the first dimension difference H can take into account both the accommodation effect of the second protrusion 108 and the overall size of the floor of the passenger compartment 1004, effectively improving the utilization of the battery placement space.

[0185] As a result, the size difference between the avoidance portion 105 and the main body portion 106 is close to the protruding size of the second protrusion 108. The setting of the cover 104 can better offset the local height difference caused by the second protrusion 108 on the passenger compartment floor 1003, thereby improving user experience.

[0186] In the embodiment of the present application, the difference between the maximum dimension H4 of the second protrusion 108 along the first direction (Z) and the first dimension difference H is less than or equal to 5 mm.

[0187] Exemplarily, the difference between the maximum dimension H4 of the second protrusion 108 along the first direction (Z) and the first dimension difference H can be 0mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm or 5mm, etc.

[0188] As a result, the size difference between the avoidance portion 105 and the main body portion 106 is further closer to the protruding size of the second protrusion 108. The setting of the cover 104 can better offset the local height difference caused by the second protrusion 108 on the passenger compartment floor 1003, thereby improving user experience.

[0189] In the embodiment of the present application, when projected along the first direction (Z) on a projection plane perpendicular to the first direction (Z), the projection of the avoidance portion 105 completely covers the projection of the second protruding portion 108 .

[0190] For example, Figure 11 As shown, the second protrusions 108 are arranged at intervals along the Y direction, and when projected along the first direction (Z) on a projection plane perpendicular to the first direction (Z), the projection of the avoidance portion 105 completely covers the projection of the second protrusion 108 .

[0191] Although not shown, the second protrusions 108 may also be arranged at intervals along the X direction. When projected along the first direction (Z) on a projection plane perpendicular to the first direction (Z), the projection of the avoidance portion 105 completely covers the projection of the second protrusion 108 .

[0192] In an embodiment of the present application, the avoidance portion 105 includes a groove, and at least a portion of the second protrusion 108 extends into the groove; or, the avoidance portion 105 includes a through hole, and at least a portion of the second protrusion 108 extends into the through hole.

[0193] Optionally, the avoidance portion 105 may be a groove or a through hole. The shapes illustrated in the drawings of this application are only for illustration of through holes and grooves, and are not limiting.

[0194] Optionally, the avoidance portion 105 may have rounded corners or chamfered corners, which is not limited in this application.

[0195] Optionally, the second protrusion 108 may partially extend into the avoidance portion 105 , or may completely extend into the avoidance portion 105 .

[0196] Therefore, according to the size of the second protrusion 108, the avoidance portion 105 on the cover 104 can be set as a groove formed by local thinning or a through hole formed by hollowing, so that the size difference between the avoidance portion 105 and the main body 106 can better adapt to the protruding size of the second protrusion 108.

[0197] In the embodiment of the present application, the first protrusions 103 are configured in plurality, the avoidance portions 105 are configured in plurality, and the plurality of avoidance portions 105 are used to accommodate the plurality of first protrusions 103 in a one-to-one correspondence along the first direction (Z).

[0198] For example, Figure 4 、 Figure 5 As shown, the first box wall 102 is formed with a plurality of first protrusions 103, which extend along the traveling direction (X) of the vehicle 1000, and the plurality of first protrusions 103 are spaced apart along the left-right direction (Y) of the vehicle 1000, and the avoidance portion 105 is also extended along the traveling direction (X) of the vehicle 1000, and the avoidance portion 105 is arranged in a one-to-one correspondence with the first protrusion 103 along the first direction (Z).

[0199] For example, Figure 8 、 Figure 9 As shown, the first box wall 102 is formed with a plurality of first protrusions 103, which extend along the left-right direction (Y) of the vehicle 1000, and the plurality of first protrusions 103 are arranged at intervals along the traveling direction (X) of the vehicle 1000, and the avoidance portions 105 are also extended along the left-right direction (Y) of the vehicle 1000, and the avoidance portions 105 are arranged one-to-one with the first protrusions 103 along the first direction (Z).

[0200] The plurality of first protrusions 103 can not only increase the total energy of the battery 100 , but also help to increase the floor area of the passenger compartment 1004 on the passenger compartment 1004 side, which can greatly improve the riding comfort.

[0201] Therefore, when there are multiple first protrusions 103 on the first box wall 102 of the battery 100, the unevenness of the passenger compartment floor 1003 caused by the influence of the first protrusions 103 can be at least partially offset by the setting of the covering part 104 through the size difference setting of multiple avoidance parts 105 and the main body 106 on the covering part 104 and the corresponding setting of the avoidance parts 105 to cover the first protrusions 103.

[0202] In the embodiment of the present application, the cover 104 is configured to be made of elastic material.

[0203] Optionally, the material of the cover 104 may be rubber or fiber, which is not limited in this application.

[0204] Optionally, the cover 104 may be a multi-layer composite structure, which may be a combination of a fabric layer, a barrier layer (such as a waterproof, insulating layer), an anti-slip layer, a sterilization layer, etc. The fabric layer may be a tufted blanket or a needle-punched blanket, etc., which the user may directly contact.

[0205] Since the cover 104 is configured with an elastic material, the resilience of the cover 104 and the flatness of the floor of the passenger compartment 1004 can be further improved, which improves the user experience and is also convenient for processing and installation.

[0206] The specific embodiments of the present application are described below with reference to the accompanying drawings.

[0207] In a specific embodiment, Figure 4 、 Figure 8 As shown, the battery 100 housing 101 is provided with a plurality of first protrusions 103 on the first wall 102. The first protrusions 103 include, but are not limited to, those spaced apart along the X direction or along the Y direction. The first protrusions 103 on the first wall 102 accommodate the electrode lead 401, the current collector 111, the sampling assembly 112, and other structures.

[0208] The first box wall 102 is a part of the vehicle floor structure. The covering member 104 laid on the first box wall 102 can accommodate the first protrusion 103 by adjusting the thickness structure at different positions.

[0209] For example, the receiving groove 107 in the first protrusion 103 not only accommodates the electrode lead 401 and related high-voltage connections, but may also accommodate other structures such as the sampling assembly 112 and the manifold 111, thereby improving the volume utilization in the first direction (Z).

[0210] For example, Figures 4 to 10As shown, the cover 104 located on the first box wall 102 (i.e., the entire vehicle floor) forms an avoidance portion 105 on the side facing the first box wall 102 by adjusting the thickness of the cover 104 at different corresponding positions. The avoidance portion 105 can accommodate the first protrusion 103 of the first box wall 102 at the corresponding position, reducing the influence of the first protrusion 103 and the electrical connection structure therein on the flatness of the ground, improving the volume utilization of the battery 100 to the entire vehicle structure, and also improving the user experience.
