[0003] This disclosure relates to the field of vehicle technology, specifically to a battery and a vehicle. Background Technology

[0004] New energy batteries are being used more and more widely in daily life and industry. For example, new energy vehicles equipped with batteries are already in widespread use.

[0005] Batteries in new energy vehicles take up interior space.

[0006] In new energy vehicles using electric drive modules, the battery capacity directly affects the vehicle's maximum driving range. Therefore, within the limited space of the vehicle, how to utilize as much space as possible for battery placement directly impacts the vehicle's maximum driving range, and is of great significance for alleviating users' range anxiety, reducing charging frequency, and improving user experience. Summary of the Invention

[0007] In view of this, the present disclosure aims to provide a battery and vehicle that can improve the utilization of vehicle interior space.

[0008] To achieve the above objectives, the technical solution of this disclosure embodiment is implemented as follows:

[0009] This disclosure provides a vehicle, the vehicle comprising:

[0010] The support plate has a raised portion, and the raised portion forms an accommodating space;

[0011] A battery is disposed on one side of the support plate where the receiving space is provided. The battery includes a receiving box and a battery assembly. The battery assembly is housed in the receiving box, and a portion of the battery assembly extends into the receiving space.

[0012] In this embodiment of the vehicle support plate, on the one hand, by providing a raised portion on the support plate, the raised portion can utilize the idle space inside the vehicle, thereby improving the utilization of the vehicle's interior space and making the vehicle structure more compact; on the other hand, the raised portion forms a receiving space, which is beneficial to increasing the space inside the vehicle that can be used to arrange battery components, and further extending a part of the battery component into the receiving space, thereby increasing the battery capacity, or, given a certain battery capacity, is beneficial to reducing the overall size of the vehicle.

[0013] In some embodiments, the battery assembly includes a protruding portion, at least a portion of which is received within the receiving space. This facilitates a more regular shape of the outer contour of the portion of the battery assembly located outside the receiving space, which in turn facilitates a more regular shape of the receiving box corresponding to that portion, and ultimately a more regular shape of the vehicle's outer contour formed by the receiving box. This reduces wind resistance. On one hand, it helps to reduce the size of the receiving box, making the battery structure more compact; on the other hand, it helps to make the vehicle's outer contour formed by the receiving box flatter, which helps to reduce the vehicle's drag coefficient and increase the vehicle's ground clearance, reducing the likelihood of increased wind resistance from the receiving box and battery damage due to collisions with road debris during vehicle operation.

[0014] In some embodiments, a portion of the projection of the battery assembly lies outside the projection of the receiving space in a projection plane perpendicular to the bulge direction. This allows the battery assembly to better utilize the space on one side of the support plate, thus improving battery capacity.

[0015] In some embodiments, the battery assembly further includes multiple battery cells, each battery cell including a housing having a first housing wall, and the protruding portion disposed on the first housing wall. This facilitates increasing the volume of the battery cells and allows the space within the housing to accommodate battery cells with different outer contour shapes, enabling a more compact arrangement of these cells within the housing and ultimately improving the battery's energy density.

[0016] In some embodiments, the battery assembly further includes a busbar, and each battery cell further includes a terminal post disposed on the first housing wall. The busbar electrically connects the terminals of two battery cells, and the protruding portion includes the busbar. At least a portion of the busbar is located within the receiving space. This allows for increased space utilization of the vehicle by utilizing the receiving space to accommodate the busbar, thereby improving the vehicle's space utilization. On the one hand, it allows for more battery cells that the busbar can electrically connect, thus increasing battery capacity. On the other hand, it allows for a more compact and orderly arrangement of different battery cells within the receiving box, which helps improve battery energy density.

[0017] In some embodiments, the terminal post is at least partially housed within the housing space. This allows for a larger space for arranging the terminal post by utilizing the housing space, which is beneficial for arranging a larger capacity battery in the vehicle; at the same time, it further improves the space utilization rate of the vehicle.

[0018] In some embodiments, the first shell wall includes a protrusion, the protruding portion includes the protrusion, and at least a portion of the protrusion is located within the receiving space. This facilitates further increasing the space within the battery cell, thereby improving battery capacity. Simultaneously, the support plate allows for a more compact structure within the vehicle, improving the utilization rate of the vehicle's interior space.

[0019] In some embodiments, the protrusion is provided with a terminal post. This is beneficial for improving the utilization efficiency of the space within the accommodating protrusion, making the arrangement between the battery and the support plate more compact, improving the energy density and space utilization of the battery, and increasing the utilization rate of the vehicle's interior space.

[0020] In some embodiments, there are two poles with opposite polarities, and both poles are located on the same protrusion. This allows for the provision of mounting positions for both poles with only one protrusion, reducing the number of manufacturing steps for the first shell wall and lowering production costs.

[0021] In some embodiments, the protrusion is located at one end of the first housing wall along its length. This maximizes the area of ​​the first housing wall at the other end, away from the protrusion, along its length. This facilitates the arrangement of other battery components with larger external dimensions within this area, providing convenience for the placement of other battery components. Simultaneously, it helps reduce the battery's volume, improves internal space utilization, and makes the battery more compact, ultimately increasing the total battery capacity in the vehicle.

[0022] In some embodiments, there are two terminals with opposite polarities, each terminal located on one of the two protrusions. This has two advantages: firstly, it reduces the volume of a single protrusion, making the structure more compact, which in turn reduces the volume of individual battery cells, allowing for the placement of more battery cells and increasing the total battery capacity in the vehicle; secondly, it allows for spacing between the two terminals, reducing the risk of short circuits between them and improving the safety of the battery cells.

[0023] In some embodiments, the two protrusions are located at one end of the first shell wall along its length. This allows a larger flat area to be formed in the portion of the first shell wall between the two protrusions. Given a fixed battery volume, this facilitates the placement of other battery components with larger external dimensions within this area, providing convenience for the arrangement of other battery components. Simultaneously, it helps reduce the battery's volume, improves the utilization of internal space, and makes the battery more compact, ultimately increasing the total battery capacity in the vehicle.

[0024] In some embodiments, the protrusion is located at the center of the first shell wall along the length of the first shell wall. This makes it easier to make the structure of the battery cell symmetrical about the first center plane, and to adjust the placement direction when multiple battery cells are arranged in the battery, thereby improving the adaptability of the battery cells in the battery.

[0025] And / or, the center position of the first shell wall along its width direction coincides with the center position of the protrusion along the width direction of the first shell wall. This further facilitates the formation of a large flat area in the width direction of the first shell wall, making it easier to arrange other components with large outer contour dimensions in the battery within this area. This provides convenience for the arrangement of other components in the battery. At the same time, it helps to reduce the volume of the battery, improve the internal space utilization of the battery, make the battery more compact, and help to increase the total battery capacity in the vehicle.

[0026] In some embodiments, the two pole posts are spaced apart along the length of the first shell wall. This maximizes the distance between the two protrusions, which helps to form a large flat area in the first shell wall between the two protrusions. This allows other components with larger outer dimensions to be arranged in this area, facilitating the arrangement of other components in the battery, while reducing the battery volume and improving the utilization rate of the internal space of the battery, thereby improving the utilization rate of the vehicle's internal space.

[0027] And / or, the two terminals are spaced apart along the width direction of the first shell wall. This arrangement of the two terminals along the width direction of the first shell wall helps to shorten the distance between terminals of different polarities between two adjacent battery cells, making it easier to achieve electrical connection between two different adjacent battery cells, and thus helping to reduce the size of the battery.

[0028] In some embodiments, the battery cell further includes an electrode assembly housed within the housing. A portion of the first housing wall is recessed to form a clearance groove located on the side of the protrusion closest to the electrode assembly, with a portion of the electrode assembly situated within the clearance groove. This allows the first housing wall to be positioned as close as possible to the electrode assembly, effectively reducing the volume within the housing while maximizing the extension of the electrode assembly into the clearance groove. This reduces redundant volume within the battery cell, resulting in a more compact internal space. Consequently, it helps reduce the overall volume and external dimensions of the battery cell, thereby increasing the number of battery cells that can be accommodated, improving the battery's energy density and space utilization.

[0029] In some embodiments, the electrode assembly includes a body and a tab, the tab being disposed on one side edge of the body and electrically connected to the body, and at least a portion of the tab being located in the clearance groove.

[0030] In some embodiments, at least a portion of the tab is located within the receiving space, which facilitates further increasing the volume of the main body in the battery cell, thereby improving the energy density of the battery cell.

[0031] In some embodiments, the battery cell further includes a terminal post disposed on the first shell wall, and the electrode assembly further includes an adapter plate. The tab is electrically connected to the terminal post through the adapter plate, and at least a portion of the tab is located in the receiving space. This is beneficial to further increase the volume of the main body in the battery cell, thereby improving the energy density of the battery cell.

[0032] And / or, at least a portion of the adapter piece is located in the receiving space, which helps to increase the space for arranging the adapter piece, thereby allowing more space to be arranged for the main body, which helps to increase the capacity of the battery cell.

[0033] In some embodiments, the battery assembly further includes a sampling member, at least a portion of which is accommodated in the accommodating space. This allows for an increase in the space available for arranging the sampling member by utilizing the accommodating space, thereby increasing the overall volume of the battery and further enhancing the battery capacity in the vehicle.

[0034] And / or, the battery assembly further includes a battery management system, at least a portion of which is housed in the housing space. This is advantageous because it increases the space available for arranging the battery management system by utilizing the housing space, thereby increasing the overall volume of the battery and further improving the capacity of the battery in the vehicle. The housing space support plate improves the space utilization of the vehicle interior and makes the portion of the battery located outside the housing space more regular in shape.

[0035] And / or, the battery assembly also includes a relay, at least a portion of which is housed in the housing space. This is advantageous because it increases the space available for arranging the relay by utilizing the housing space, thereby increasing the overall volume of the battery and further improving the battery capacity in the vehicle. The housing space support plate improves the space utilization of the vehicle interior and makes the portion of the battery located outside the housing space more regular in shape.

[0036] And / or, the battery assembly further includes a high-voltage power distribution unit, at least a portion of which is housed in the housing space. This is advantageous because it increases the space available for arranging the high-voltage power distribution unit by utilizing the housing space, thereby increasing the overall volume of the battery. It is also advantageous because it increases the capacity of the battery housing space support plate in the vehicle, improves the space utilization rate of the vehicle interior, and makes the shape of the battery portion outside the housing space more regular.

[0037] And / or, the battery assembly also includes high and low voltage wiring harnesses, at least a portion of which are housed in the housing space. This is advantageous because it increases the space available for arranging the high and low voltage wiring harnesses by utilizing the housing space, reduces bending of the high and low voltage wiring harnesses, increases the overall volume of the battery, and further improves the battery capacity in the vehicle.

[0038] In some embodiments, the length of the battery cell is not less than 350 mm, which is beneficial for the electrochemical reaction of the electrode components and electrolyte within the battery cell to store or release sufficient electrical energy, and for the total electrical energy in the battery to meet the demand.

[0039] And / or, the width of the battery cell ranges from 5mm to 50mm, which makes the size of the battery cell easy to handle and better fits the size of different housing boxes;

[0040] And / or, the height of the battery cell ranges from 80mm to 200mm, which makes the size of the battery cell easy to handle and better fits different sizes of housing boxes.

[0041] In some embodiments, the height of the protrusion within the receiving space ranges from 2 mm to 10 mm, thereby improving the space utilization within the receiving space.

[0042] In some embodiments, the vehicle also includes a seat located on the side of the support plate where the raised portion is formed. This increases the volume of the battery inside the vehicle, thereby increasing battery capacity and improving the vehicle's driving range. Simultaneously, it allows the flat walls of the storage compartment to face the ground, resulting in a smoother underside of the vehicle, reducing the vehicle's drag coefficient and increasing ground clearance. This reduces the likelihood of battery damage due to increased wind resistance from the raised portion or collisions with road debris during driving.

[0043] In some embodiments, in a projection perpendicular to the height of the vehicle, part or all of the projection of the hump is located within the projection range of the seat. In this way, the hump utilizes the space under the seat, reducing the probability of the occupant touching the hump during the ride, thereby reducing the encroachment of the hump on the occupant's normal activity space, improving the user experience, and increasing the space utilization rate inside the vehicle.

[0044] In some embodiments, the number of seats is at least two, and a first gap is formed between two adjacent seats along the width direction of the vehicle. The raised portion includes a first raised portion, and part or all of the first raised portion is located in the first gap. In this way, the first raised portion can utilize the space in the first gap, thereby increasing the battery volume while reducing the probability of the occupant touching the first raised portion during the ride, reducing the interference of the first raised portion on the occupant's normal activities, and improving the space utilization rate inside the vehicle.

[0045] In some embodiments, there are multiple seats, which are arranged in at least two rows spaced apart along the length of the vehicle. The first bulge extends along the length of the vehicle to the underside of the adjacent row of seats. This increases the volume of the first bulge, thereby increasing the volume of the space within the first bulge, which in turn increases the volume of the battery and its capacity.

[0046] In some embodiments, the raised portion includes a second raised portion that extends along the length direction of the vehicle and is located on one side of the support seat along the width direction of the vehicle. This reduces the interference of the second raised portion with the leg and foot movements of the occupant, thereby improving the occupant's user experience.

[0047] In some embodiments, there are two second protrusions, each located at one end of the support plate along the width of the vehicle, and the seat is located between the two second protrusions. This arrangement can increase the space for the occupant's legs and feet to move, thus improving the occupant's user experience. At the same time, the arrangement of the second protrusions effectively utilizes the space along the width of the vehicle.

[0048] In some embodiments, the second bulge and the seat are spaced apart along the width direction of the vehicle, which helps to increase the leg and foot space of the occupant and improve the user's riding experience;

[0049] And / or, a portion of the second raised portion is located below the seat, which helps to reduce the size of the support plate in the width direction, making the vehicle structure more compact.

[0050] In some embodiments, the raised portion includes a third raised portion extending along the width direction of the vehicle. The number of seats is plurality of seats, arranged in at least two rows spaced apart along the length direction of the vehicle. At least a portion of the third raised portion is located below the seats in the same row. Thus, the third raised portion better utilizes the space under the seats along the width direction of the vehicle, while simultaneously reducing encroachment on the space between adjacent rows of seats, minimizing interference with occupant activities, and improving the occupant experience.

[0051] In some embodiments, the seat includes a seat base, at least a portion of which is spaced apart from the support plate in the height direction of the vehicle to form a second gap, and at least a portion of the raised portion is located in the second gap and spaced apart from the seat base in the height direction of the vehicle. This reduces the likelihood of the raised portion being damaged by the pressure of the occupant sitting on it due to direct contact between the raised portion and the seat base.

[0052] In some embodiments, the seat includes a support leg, and the seat and the support plate are spaced vertically to form a second gap. The support leg is connected between the seat and the support plate. This facilitates the spacing between the seat and the raised portion, which helps to make the seat shape regular and easy to place. At the same time, it allows the occupant to put their feet into the second gap, making it easier for the occupant to stretch out their sitting posture and improve riding comfort.

[0053] In some embodiments, there are multiple legs, which are spaced apart along the width direction of the vehicle. Part or all of the raised portion is located between two adjacent legs along the width direction of the vehicle. This facilitates the arrangement of the raised portion to utilize the space between the two legs, which helps to improve the space utilization rate of the battery in the vehicle's interior space and increase the battery capacity.

[0054] In some embodiments, the seat includes a cushioning pad, and the raised portion is embedded in the cushioning pad to support the seat along the height direction of the vehicle. This helps to simplify the structure of the seat, improve the utilization of the interior space of the seat, and reduce production costs.

[0055] In some embodiments, one side of the housing is open to form a first opening, and the support plate is placed over the first opening to jointly enclose and form a housing cavity. The battery assembly is placed in the housing cavity. This simplifies the vehicle structure and makes the arrangement between the support plate and the battery more compact. Given a fixed volume of the vehicle's interior space, this increases the battery capacity. At the same time, it facilitates the direct access to the battery assembly for maintenance after the battery is removed from the vehicle, allowing for easy removal of the battery from the vehicle.

[0056] In some embodiments, the raised portion includes a raised body and a first sealing cover. The raised body has a through first hole that communicates with the receiving space. The first sealing cover is detachably connected to the raised body to seal the first through hole. Thus, when the battery needs to be inspected and maintained, the battery assembly located in the receiving space can be inspected from inside the vehicle through the first opening and the first through hole by removing the first sealing cover, without the need to disassemble the battery. This increases the working space for maintenance personnel and improves the convenience of maintenance work.

[0057] In some embodiments, the raised portion further includes a first sealing element, which is arranged around the periphery of the first through hole and sandwiched between the raised body and the first sealing cap to seal the area between the raised body and the first sealing cap. This reduces the seam space between the areas where the raised body and the first sealing cap contact the first sealing element, thereby reducing the probability of foreign objects entering the cavity and affecting the battery's operation, extending the battery's lifespan, and improving battery safety.

[0058] In some embodiments, the first sealing cap is installed on the raised body using threaded fasteners. This method of using threaded fasteners facilitates disassembly and improves the connection strength between the first sealing cap and the raised body; or...

[0059] The first sealing cover is slidably engaged with the raised body. This sliding mechanism allows the first sealing cover to open or close the first through-hole more quickly, improving ease of maintenance; or...

[0060] The first sealing cover is hinged to the raised body. Thus, by rotating, the first sealing cover can be opened or closed more quickly, improving the convenience of maintenance.

[0061] In some embodiments, the battery includes a temperature control component sandwiched between the support plate and the battery assembly. This allows the temperature control component to absorb heat generated during the battery assembly's operation, reducing the battery assembly's operating temperature and improving battery safety. Simultaneously, it reduces heat transferred from the battery assembly to the support plate and radiated into the vehicle interior during operation. Furthermore, it better utilizes the larger area of ​​the support plate, increasing the contact area between the temperature control component and the battery assembly, thus improving temperature control effectiveness.

[0062] In some embodiments, the battery includes a first adhesive layer that adheres between the support plate and the outer surface of the temperature control component, thereby fixing the relative position between the temperature control component and the support plate and reducing the probability of frictional damage caused by relative movement between the two.

[0063] And / or, the battery includes a third adhesive layer that adheres between the temperature control component and the outer surface of the battery assembly, thereby fixing the relative position between the temperature control component and the battery assembly and reducing the probability of frictional damage caused by relative movement between them.

[0064] In some embodiments, the battery assembly further includes a battery cell, the battery cell including a housing having a first housing wall, the first housing wall including a protrusion, at least a portion of the protrusion being located in the receiving space, the height of the protrusion not exceeding 77% of the height of the raised portion. This, on the one hand, facilitates the spacing between the protrusion and the receiving space along the height direction of the battery, reducing the probability of direct contact and damage, and also facilitates the arrangement of other components of the battery assembly in the receiving space; on the other hand, it allows the thickness of the raised portion to better protect the protrusion.

[0065] In some embodiments, the height of the protrusion accounts for 21% to 53% of the height of the raised portion. This further ensures that the size of the accommodating space meets the needs of arranging other components of the battery assembly; and further facilitates that the raised portion has sufficient strength to protect the protrusion.

[0066] In some embodiments, the battery assembly includes individual battery cells, each battery cell including terminals, with at least two terminals of the battery cells located within the same receiving space. This facilitates electrical connection of the terminals of different battery cells within a single receiving space, resulting in a more compact battery structure.

[0067] In some embodiments, the vehicle includes a second insulator disposed on the inner wall of the receiving space. Thus, by utilizing the insulating properties of the second insulator, the risk of charge transfer between the battery assembly and the inner wall of the receiving space can be reduced, thereby mitigating the risk of short circuits and other problems during battery use.

[0068] In some embodiments, the battery assembly includes a battery cell, the battery cell includes a terminal post, and the second insulating member is disposed opposite to the terminal post. This reduces the probability of the terminal post contacting the support plate due to relative movement between the battery assembly and the support plate, thus reducing the risk of a short circuit in the battery cell caused by contact between the terminal post and the support plate.

[0069] In some embodiments, the battery assembly further includes a busbar, at least a portion of which is located within the receiving space. The distance between the inner wall of the receiving space and the busbar along a first direction is not less than 1% of the dimension of the receiving space along the first direction, where the first direction is perpendicular to the protrusion direction of the raised portion. This helps to reduce the probability of the busbar contacting the inner wall of the receiving space, and reduces the probability of a short circuit due to contact between the busbar and the support plate.

[0070] In some embodiments, the distance between the inner wall of the receiving space and the manifold along the first direction is in the range of 2% to 10% of the dimension of the receiving space along the first direction. This further helps to reduce the probability of the manifold coming into contact with the inner wall of the receiving space.

[0071] In some embodiments, the housing includes a first wall located on the side of the housing facing the support plate, with a portion of the first wall extending into the housing space. In this way, on the one hand, the first wall can protect the battery assembly during the separate transport of the battery; on the other hand, it reduces the probability of the battery assembly coming into contact with the support plate, and reduces the probability of battery leakage or other problems causing adverse effects on other components and personnel in the vehicle.

[0072] In some embodiments, the housing includes a housing body and a lid, with the first housing wall forming the lid. One side of the housing body is open to form a second opening, and the lid is placed over the second opening to form a housing cavity with the housing body. The battery assembly is placed inside the housing cavity. Thus, the housing is formed by splicing the housing body and the lid, which facilitates disassembling the housing as needed for inspection and maintenance of the battery assembly.

[0073] In some embodiments, the first enclosure wall includes an enclosure wall body and a second sealing cover. The enclosure wall body has a through second through hole that communicates with the receiving cavity. The second sealing cover is detachably connected to the enclosure wall body to seal the second through hole. Thus, when the battery is separated from the vehicle, the battery assembly located in the receiving cavity can be inspected and maintained through the second through hole simply by removing and installing the second sealing cover, thereby improving the convenience and efficiency of inspection and maintenance.

[0074] In some embodiments, the cover further includes a second sealing element, which is arranged around the periphery of the second through hole and sandwiched between the box wall body and the second sealing cover to seal the box wall body and the second sealing cover. This reduces the seam space between the box wall body and the second sealing cover and the second sealing element, thereby reducing the probability of foreign objects entering the cavity and affecting the operation of the battery assembly, extending the battery's lifespan, and improving battery safety.

[0075] In some embodiments, the second sealing cover is installed to the box wall body using threaded fasteners. This method of using threaded fasteners facilitates disassembly and improves the connection strength between the second sealing cover and the box wall body; or...

[0076] The second sealing cover is slidably engaged with the box wall body. This sliding mechanism allows the second sealing cover to be opened or closed more quickly, improving the convenience of maintenance; or...

[0077] The second sealing cover is hinged to the box wall body. In this way, by rotating, the second sealing cover can be opened or closed more quickly, improving the convenience of maintenance.

[0078] In some embodiments, the raised portion includes a raised body and a first sealing cover. The raised body has a through first hole that communicates with the receiving space. The first sealing cover is detachably connected to the raised body to seal the first through hole. The second through hole is disposed opposite to the first through hole. Thus, when the first and second sealing covers are removed, the vehicle interior space, the receiving space, and the receiving cavity are interconnected, and the receiving space and the receiving cavity are disposed opposite to each other. This facilitates maintenance personnel to directly perform maintenance work on the battery assembly from inside the vehicle without removing the battery from the vehicle, thereby improving the convenience of maintenance work and increasing work efficiency.

[0079] In some embodiments, the battery includes a temperature control component sandwiched between the first housing wall and the battery assembly. In this way, the temperature control component absorbs the heat generated during the operation of the battery assembly, reducing the operating temperature of the battery assembly and improving the safety of battery use. At the same time, the temperature control component can directly radiate some of the heat to the outside through the housing wall, increasing the heat dissipation area and improving the temperature control effect.

[0080] In some embodiments, the battery includes a second adhesive layer that adheres between the first casing wall and the outer surface of the temperature control component. This fixes the relative position between the temperature control component and the first casing wall, reducing the likelihood of frictional damage caused by relative movement between them.

[0081] And / or, the battery includes a third adhesive layer that adheres between the temperature control component and the outer surface of the battery assembly, thereby fixing the relative position between the temperature control component and the battery assembly and reducing the probability of frictional damage caused by relative movement between them.

[0082] In some embodiments, a portion of the first housing wall protrudes to form a boss, at least a portion of which extends into the receiving space. The side of the boss facing away from the receiving space forms a receiving portion, and a portion of the battery assembly is located in the receiving portion. Thus, by using the receiving portion, a portion of the battery assembly is located in the receiving space, which protects the battery assembly located in the receiving space from the boss and reduces the probability of direct contact between the battery assembly and the support plate. At the same time, it is beneficial to make the area with the protrusion on the first housing wall consistent with the other parts of the thickness, which is beneficial to reduce the overall size of the first housing wall, thereby reducing the three-dimensional size of the receiving box, reducing the overall volume of the battery, and facilitating the improvement of the battery's energy density and space utilization.

[0083] In some embodiments, the height of the boss does not exceed 98.5% of the height of the raised portion. This reduces the likelihood that the boss will abut against the inner wall of the accommodating space along the height direction, thus affecting the arrangement between the battery and the support plate.

[0084] In some embodiments, the height of the boss accounts for 33.3% to 53% of the height of the raised portion. This, on the one hand, further reduces the likelihood of the boss abutting against the inner wall of the receiving space along the height direction; on the other hand, it allows for a larger space within the receiving portion for accommodating the battery assembly.

[0085] In some embodiments, the battery assembly further includes a battery cell, the battery cell including a housing, the housing having a first housing wall, the first housing wall including a protrusion, at least a portion of the protrusion being located in the receiving portion, the height of the protrusion not exceeding 77% of the height of the boss. This, on the one hand, facilitates a spacing between the protrusion and the receiving portion along the height direction of the battery, reducing the probability of direct contact and damage, and also facilitates the arrangement of other components of the battery assembly in the receiving portion; on the other hand, it allows the thickness of the first housing wall to better protect the protrusion.

[0086] In some embodiments, the height of the protrusion accounts for 36% to 53% of the height of the boss. This further reduces the likelihood of damage caused by direct contact between the two and is more conducive to arranging other components of the battery assembly in the receiving section.

[0087] In some embodiments, the battery assembly includes a protrusion, at least a portion of which is located within the receiving portion, and the height of the protrusion does not exceed 94% of the height of the boss. This helps to reduce the probability of the protrusion and the boss abutting in the vertical direction, thus reducing the probability of damage caused by such contact.

[0088] In some embodiments, the height of the protrusion accounts for 74% to 86% of the height of the boss. This further reduces the likelihood of the protrusion and the boss abutting in the vertical direction, and improves the space utilization of the receiving portion by the protrusion.

[0089] In some embodiments, the battery assembly further includes a busbar, at least a portion of which is located within the housing. The distance between the inner wall of the housing and the busbar along a first direction is not less than 1% of the dimension of the housing along the first direction, where the first direction is perpendicular to the thickness direction of the first housing wall. This helps reduce the probability of a short circuit caused by contact between the busbar and the inner wall of the housing, allowing the battery assembly to function normally.

[0090] In some embodiments, the distance between the inner wall of the receiving portion and the busbar along the first direction is in the range of 2% to 10% of the dimension of the receiving portion along the first direction. This further helps to reduce the probability of short circuit caused by contact between the busbar and the inner wall of the receiving portion.

[0091] In some embodiments, the battery assembly includes individual battery cells, each battery cell including terminals, with at least two terminals of the battery cells located within the same receiving portion. This facilitates electrical connection of the terminals of different battery cells within a single receiving portion, resulting in a more compact battery structure.

[0092] In some embodiments, the battery includes a first insulating member disposed on the inner wall of the housing. This reduces the risk of charge transfer between the battery assembly and the inner wall of the housing, thereby reducing the risk of short circuits and other problems during battery use.

[0093] In some embodiments, the battery assembly includes a battery cell, and the battery cell includes a terminal post, with the first insulating member disposed opposite to the terminal post. This reduces the likelihood of the terminal post contacting the first casing wall due to relative movement between the battery assembly and the first casing wall, thereby reducing the risk of a short circuit in the battery cell caused by contact between the terminal post and the first casing wall.

[0094] In some embodiments, the cover includes a box wall body and a second sealing cover. The box wall body has a through second through hole that communicates with the receiving cavity. The second sealing cover is detachably connected to the box wall body to cover the second through hole. Part or all of the boss forms the second sealing cover, which facilitates the disassembly and assembly of the boss for the inspection and maintenance of the battery assembly.

[0095] In some embodiments, the length direction of the boss is the same as the length direction of the receiving cavity, and the dimensions of both along the length direction are the same. This is beneficial to maximize the dimension of the receiving portion along the length direction of the battery, thereby making it easier for the size and volume of the receiving portion to adapt to battery assemblies of various sizes and shapes.

[0096] Alternatively, the length direction of the boss is the same as the width direction of the receiving cavity, and the length dimension of the boss is the same as the width dimension of the first box wall. This is beneficial to maximize the dimension of the receiving part along the width direction of the battery, thereby making it easier for the size and volume of the receiving part to adapt to various battery assemblies of different sizes and shapes.

[0097] In some embodiments, the width of the boss does not exceed 500mm. This has two advantages: firstly, it allows the surface of the first box wall to have a larger flat area, so as to adapt to other parts in the vehicle and reduce the adverse effects of the boss on the arrangement of other parts in the vehicle; secondly, it reduces the adverse effects of the boss's large width causing a decrease in its structural strength and reduces the probability of damage to the parts in the receiving part due to the deformation of the boss.

[0098] And / or, the height of the boss does not exceed 300mm, which facilitates the adaptation to other components in the vehicle and reduces the adverse effects of the boss on the arrangement of other components in the vehicle; at the same time, it reduces the probability that the boss will be deformed and bent due to shear stress perpendicular to the height direction, thus damaging the battery assembly in the housing.

[0099] In some embodiments, the width of the boss ranges from 50mm to 300mm, thus facilitating the arrangement of the battery assembly within the receiving section.

[0100] And / or, the height of the boss ranges from 5mm to 100mm, so that the space within the receiving part can meet the arrangement requirements of the protruding part.

[0101] In some embodiments, the width of the raised portion does not exceed 500mm, thus facilitating the arrangement of the battery assembly within the accommodating portion.

[0102] And / or, the height of the raised portion does not exceed 300mm, thus adapting to other components in the vehicle and reducing the adverse effects of the raised portion on the arrangement of other components in the vehicle; at the same time, it reduces the probability that the raised portion will be deformed and bent due to shear stress perpendicular to the height direction, thereby damaging the battery assembly in the housing.

[0103] This disclosure also provides a battery for a vehicle, the vehicle including a support plate, the battery located on one side of the support plate, the support plate having a raised portion disposed opposite to the battery, the raised portion forming a receiving space on the side facing the battery, the battery including a receiving box and a battery assembly, the battery assembly being received in the receiving box, the battery assembly including a protruding portion for protruding toward the support plate to extend into the receiving space, and in a projection plane perpendicular to the protrusion direction of the protruding portion, the projection of a portion of the battery assembly is located outside the projection of the protruding portion.

[0104] This allows the battery to make better use of the space created by the raised section, resulting in a more compact battery structure and improving the battery capacity in the vehicle.

[0105] In some embodiments, the housing has a placement space where the battery assembly is placed. One side of the placement space is open to form a first opening, which is used for the support plate to cover it. This simplifies the structure of the battery and the vehicle, making the arrangement between the support plate and the battery more compact. Given a fixed volume of interior space in the vehicle, this increases the battery capacity. At the same time, it facilitates the direct access to the battery assembly for maintenance after the battery is removed from the vehicle, allowing for easy removal of the battery from the vehicle.

[0106] In some embodiments, the battery includes a temperature control component disposed on the side of the battery assembly facing the first opening. In this way, the temperature control component absorbs the heat generated during the operation of the battery assembly, thereby reducing the operating temperature of the battery assembly and improving the safety of battery use. At the same time, it reduces the heat transferred to the support plate and radiated into the vehicle interior during the operation of the battery assembly.

[0107] In some embodiments, the battery includes a first adhesive layer for bonding the support plate to the outer surface of the temperature control component. In this way, the relative position between the temperature control component and the support plate is fixed by the first adhesive layer, reducing the probability of friction damage caused by relative movement between the two.

[0108] And / or, the battery includes a third adhesive layer that adheres between the temperature control component and the outer surface of the battery assembly, thereby fixing the relative position between the temperature control component and the battery assembly and reducing the probability of frictional damage caused by relative movement between them.

[0109] In some embodiments, the housing includes a first wall located on one side of the housing, a portion of which extends into the housing space. Thus, during individual battery transport, the first wall can protect the battery assembly and reduce the likelihood of damage caused by impacts.

[0110] In some embodiments, the housing includes a housing body and a lid, with the first housing wall forming the lid. One side of the housing body is open to form a second opening, and the lid is placed over the second opening to form a housing cavity with the housing body. The battery is placed inside the housing cavity. Thus, the housing is formed by splicing the housing body and the lid, which facilitates disassembling the housing as needed to install the battery assembly into the housing and for subsequent inspection and maintenance of the battery assembly.

[0111] In some embodiments, the first enclosure wall includes an enclosure wall body and a second sealing cover. The enclosure wall body has a through second through hole that communicates with the receiving cavity. The second sealing cover is detachably connected to the enclosure wall body to seal the second through hole. In this way, the battery assembly located in the receiving cavity can be inspected and maintained through the second through hole by simply removing and installing the second sealing cover, without having to disassemble the enclosure body and the enclosure cover, thereby improving the convenience and efficiency of inspection and maintenance.

[0112] In some embodiments, the cover further includes a second sealing element, which is arranged around the periphery of the second through hole and sandwiched between the box wall body and the second sealing cover to seal the box wall body and the second sealing cover. In this way, the second sealing element reduces the seam space between the box wall body and the second sealing cover and the contact area of ​​the second sealing element, thereby reducing the probability of foreign objects entering the cavity and affecting the operation of the battery assembly, extending the battery's service life, and improving battery safety.

[0113] In some embodiments, the second sealing cover is installed to the box wall body using threaded fasteners. This method of using threaded fasteners facilitates disassembly and improves the connection strength between the second sealing cover and the box wall body; or...

[0114] The second sealing cover is slidably engaged with the box wall body. This sliding mechanism allows the second sealing cover to be opened or closed more quickly, improving the convenience of maintenance; or...

[0115] The second sealing cover is hinged to the box wall body. In this way, by rotating, the second sealing cover can be opened or closed more quickly, improving the convenience of maintenance.

[0116] In some embodiments, on the outer surfaces of opposite sides of a portion of the first housing wall, one side protrudes to form a boss, and the other side forms a receiving portion. At least a portion of the boss extends into the receiving space, and a portion of the battery assembly is located in the receiving portion. Thus, the receiving portion allows a portion of the battery assembly to be located in the receiving space, protecting the battery assembly located in the receiving space from the boss and reducing the probability of direct contact between the battery assembly and the support plate. At the same time, it is beneficial to make the area with the protrusion on the first housing wall consistent with the other thicknesses, which helps to reduce the overall size of the first housing wall, thereby reducing the three-dimensional size of the receiving box, reducing the overall volume of the battery, and facilitating the improvement of battery energy density and space utilization.

[0117] In some embodiments, the cover includes a box wall body and a second sealing cover. The box wall body has a through second through hole that communicates with the receiving cavity. The second sealing cover is detachably connected to the box wall body to cover the second through hole. Part or all of the boss forms the second sealing cover, which facilitates the disassembly and assembly of the boss for the inspection and maintenance of the battery assembly.

[0165] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this disclosure can be combined with each other, and the detailed descriptions in the specific embodiments should be understood as explanations of the purpose of this disclosure and should not be regarded as undue limitations on this disclosure.

[0166] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure; the terms “comprising” and “having”, and any variations thereof, in the specification and the foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0167] Currently, new energy batteries are being used more and more widely in daily life and industry. They are not only used in energy storage systems for hydropower, thermal power, wind power, and solar power plants, but also in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields.

[0168] Figure 1 This is a schematic diagram of the structure of a vehicle 100 provided in one embodiment of this disclosure. The vehicle 100 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle, etc. Figure 17 As shown, a battery 10 is installed inside the vehicle 100. The battery 10 can be located at the bottom, front, or rear of the vehicle 100. The battery 10 can be used to power the vehicle 100; for example, the battery 10 can serve as the operating power source for the vehicle 100. The vehicle 100 may also include a controller 30 and a motor 40. The controller 30 is used to control the battery 10 to supply power to the motor 40, for example, to meet the power needs of the vehicle 100 during startup, navigation, and driving.

[0169] In some embodiments of this disclosure, the battery 10 can not only serve as the operating power source for the vehicle 100, but also as the driving power source for the vehicle 100, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 100.

[0170] In this embodiment of the disclosure, the battery can be a single battery cell. A single battery cell refers to a basic unit capable of converting chemical energy into electrical energy, and can be used to manufacture battery modules or battery packs to supply power to the vehicle 100. A single battery cell can be a rechargeable battery, which is a battery cell that can be recharged after discharge to activate its active materials and continue to be used. A single battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and this embodiment of the disclosure is not limited to these types.

[0171] A single battery cell typically includes an electrode assembly. The electrode assembly includes a positive electrode, a negative electrode, and a separator. During the charging and discharging process of a single battery cell, active ions (such as lithium ions) repeatedly insert and extract between the positive and negative electrodes. The separator, positioned between the positive and negative electrodes, prevents short circuits while allowing active ions to pass through.

[0172] In some embodiments, the battery cell further includes an electrolyte, which acts as a conductor of ions between the positive and negative electrodes. This disclosure does not impose specific limitations on the type of electrolyte, which can be selected according to requirements. The electrolyte can be liquid, gel, or solid.

[0173] In some embodiments, a single battery cell may include a housing. The housing is used to encapsulate components such as electrode assemblies and electrolytes. The housing may be made of steel, aluminum, plastic (such as polypropylene), composite metal (such as copper-aluminum composite), or aluminum-plastic film, etc.

[0174] As an example, the battery cell can be a cylindrical battery cell, a prismatic battery cell, a pouch battery cell, or a battery cell of other shapes. Prismatic battery cells include prismatic battery cells, blade-shaped battery cells, and multi-prismatic batteries, such as hexagonal prismatic batteries. This disclosure does not impose any particular limitations.

[0175] In some embodiments, the housing includes an end cap and a shell, the shell having an opening, and the end cap closing the opening to form a sealed space for accommodating substances such as electrode assemblies and electrolytes. The shell may have one or more openings. The end cap may also be provided one or more times.

[0176] In some embodiments, the housing is provided with at least one electrode terminal, which is electrically connected to a tab. The electrode terminal can be directly connected to the tab or indirectly connected to the tab via an adapter. The electrode terminal can be located on an end cap or on the housing. In some embodiments, the housing is provided with a pressure relief mechanism. The pressure relief mechanism is used to release the internal pressure of the battery cell.

[0177] In embodiments of this disclosure, the battery may also be a single physical module (e.g., a battery module or battery pack) comprising one or more battery cells to provide higher voltage and capacity. When there are multiple battery cells, the multiple battery cells are connected in series, parallel, or in a mixed configuration via a busbar.

[0178] In the description of the embodiments of this disclosure, technical terms such as "first," "second," and "third" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary or secondary relationship of the indicated technical features. In the description of the embodiments of this disclosure, "a plurality of" means two or more, unless otherwise explicitly defined.

[0179] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this disclosure. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0180] In the description of the embodiments of this disclosure, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects are in an "or" relationship.

[0181] In the description of the embodiments of this disclosure, for ease of explanation, as follows: Figure 2 , Figure 5 , Figure 7 , Figure 11 , Figure 13 , Figure 14 , Figure 24 , Figure 36 , Figure 37 , Figure 41 , Figure 42 As shown by the arrows, the direction of arrow X represents the "height direction of the battery" and the "height direction of the vehicle," x1 points to the "top," x2 points to the "bottom," the direction of arrow Y represents the "length direction of the battery" and the "length direction of the vehicle," and the direction of arrow Z represents the "width direction of the battery" and the "width direction of the vehicle." Figures 17 to 22 As shown by the arrows in the diagram, the direction of arrow a is the "length direction of the battery cell" and the "length direction of the first shell wall", the direction of arrow b is the "width direction of the battery cell" and the "width direction of the first shell wall", and the direction of arrow c is the "height direction of the battery cell".

[0182] In the description of the embodiments of this disclosure, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0183] In the description of the embodiments of this disclosure, unless otherwise expressly specified and limited, the technical term "contact" should be interpreted broadly, and can be direct contact, contact through an intermediate medium layer, contact between two contacting parties with substantially no interaction force, or contact between two contacting parties with interaction force.

[0184] The embodiments of this disclosure will now be described in detail.

[0185] In related technologies, a support plate is provided in the vehicle. The top side of the support plate forms an interior space, which is used to place various parts and goods in the vehicle and to accommodate passengers, while the support plate serves a load-bearing function.

[0186] The battery is positioned on the side of the support plate away from the vehicle interior space. This allows the support plate to separate the battery from the vehicle interior space, reducing the likelihood of damage to people and objects inside the vehicle if the battery malfunctions. At the same time, the large area of ​​the support plate provides a larger area for the battery to be installed, allowing for the placement of larger capacity batteries.

[0187] Because the shapes and sizes of the components installed in the vehicle interior vary, unused space is created, which negatively impacts the space utilization rate of the vehicle interior. At the same time, in order to increase the battery capacity of the vehicle, it is necessary to further improve the space utilization rate to increase the battery capacity, given the inconvenience of the overall vehicle volume.

[0188] Based on this, the present disclosure provides a vehicle in which a portion of the battery is located in a raised portion on the floor, thereby reducing the idle space in the vehicle interior and improving the utilization rate of the vehicle interior space, which is beneficial to increasing the battery capacity.

[0189] Specifically, see Figures 2 to 12 This disclosure provides a vehicle 100, which includes a support plate 50 and a battery 10.

[0190] The support plate 50 has a raised portion 51, and the raised portion 51 has a receiving space 51a.

[0191] The battery 10 is disposed on the side of the support plate 50 where the receiving space 51a is provided. The battery 10 includes a receiving box 11 and a battery assembly 12. The battery assembly 12 is housed in the receiving box 11, and a part of the battery assembly 12 extends into the receiving space 51a.

[0192] The support plate 50 is located at the bottom of the vehicle 100. The support plate 50, together with other components inside the vehicle 100, such as the body, together form the interior space 100a. The interior space 100a can be used to house functional components such as the controller 30 and motors inside the vehicle 100, to house interior trim, and to carry passengers and cargo. That is, the interior space 100a on one side of the support plate 50 can be the equipment compartment, passenger compartment, or storage compartment of the vehicle 100. For example, in an embodiment where the interior space 100a on one side of the support plate 50 is the passenger compartment of the vehicle 100, the support plate 50 forms the floor of the passenger compartment.

[0193] The raised portion 51 protrudes from the top surface of the other parts of the support plate 50 along the thickness direction of the support plate 50.

[0194] The thickness direction of the support plate 50 can be the height direction of the vehicle 100.

[0195] The raised portion 51 is located on the side of the support plate 50 facing the interior space 100a. In other words, the raised portion 51 achieves the purpose of utilizing the unused space in the interior space 100a by raising towards the interior space 100a.

[0196] The raised portion 51 encloses and forms a receiving space 51a.

[0197] The support plate 50 has one side with a receiving space 51a, see reference. Figure 2 and Figure 3 It can be that the support plate 50 is on the side opposite to the interior space 100a.

[0198] The housing 11, which forms the outer contour of the battery 10, is used to house other components of the battery 10 besides the housing 11, thereby providing space for the installation and fixing of other components. At the same time, it plays a role in sealing and protecting the battery 10, reducing the adverse effects on the normal operation of the battery 10 caused by collisions with external objects and the entry of foreign objects during transportation and use.

[0199] Battery assembly 12 refers to the various components in battery 10 used to enable the charging and discharging functions of battery 10.

[0200] The battery assembly 12 is located inside the housing 11 so that the housing 11 can protect and seal the battery assembly 12, enabling the battery assembly 12 to perform normal charging and discharging functions.

[0201] A portion of the battery assembly 12 extends into the receiving space 51a, that is, one side of the receiving space 51a is open so that the battery 10 can enter the receiving space 51a through the open position of the receiving space 51a until a portion of the battery assembly 12 enters the receiving space 51a, so that the arrangement of the battery assembly 12 can utilize the space within the protrusion 51.

[0202] In this embodiment of the vehicle 100, on the one hand, by providing a raised portion 51 on the support plate 50, the raised portion 51 can utilize the idle space of the vehicle interior space 100a, thereby improving the utilization of the interior space of the vehicle 100 and making the structure of the vehicle 100 more compact; on the other hand, the raised portion 51 forms a receiving space 51a, which is beneficial to increasing the space inside the vehicle 100 that can be used to arrange the battery assembly 12, and further extending a part of the battery assembly 12 into the receiving space 51a, thereby increasing the capacity of the battery 10, or, given a certain capacity of the battery 10, reducing the overall size of the vehicle 100.

[0203] In some embodiments, the battery 10 is disposed below the support plate 50 such that the battery 10 can form part of the chassis of the vehicle 100 and the surface of the battery 10 forms part of the outer contour surface of the vehicle 100.

[0204] It is understandable that the outer contour of the battery module 12 is not regular due to the influence of the type, size, number and arrangement of various components within the battery module 12.

[0205] In some embodiments, see Figure 5 , Figure 6 , Figure 11 and Figure 12 The battery assembly 12 includes a protrusion 12a, at least a portion of which is received in a receiving space 51a.

[0206] The protruding portion 12a refers to a part that protrudes from other adjacent parts on the outer contour surface formed by the battery assembly 12. It can be one or more components of the battery assembly 12, or it can be a part of the structure of a certain component of the battery assembly 12.

[0207] This makes it easier to make the outer contour of the part of the battery assembly 12 outside the housing space 51a regular, which in turn makes the shape of the housing box 11 covering this part regular, and makes the outer contour of the vehicle 100 formed by the housing box 11 regular, which helps to reduce wind resistance. On the one hand, it helps to reduce the size of the housing box 11, making the structure of the battery 10 more compact; on the other hand, it helps to make the outer contour of the vehicle 100 formed by the housing box 11 flatter, which helps to reduce the wind resistance coefficient of the vehicle 100 and increase the ground clearance of the vehicle 100, reducing the possibility of the housing box 11 increasing wind resistance and colliding with foreign objects on the road during the driving process, which could damage the battery 10.

[0208] In some embodiments, see Figure 5 , Figure 6 , Figure 11 and Figure 12 In the projection plane perpendicular to the bulge direction of the bulge 51, a portion of the projection of the battery assembly 12 is located outside the projection of the receiving space 51a.

[0209] A portion of the projection of the battery assembly 12 is located outside the projection of the housing space 51a, that is, a portion of the battery assembly 12 is located in the housing space 51a and another portion is located outside the housing space 51a.

[0210] This allows the battery assembly 12 to better utilize the space on one side of the support plate 50, which is beneficial for increasing the capacity of the battery 10.

[0211] The specific manner in which the protruding portion 12a is formed is not limited.

[0212] In some embodiments, see Figures 17 to 20 The battery assembly 12 also includes a plurality of battery cells 121. Each battery cell 121 includes a housing 1211, the housing 1211 having a first housing wall 1212, and a protruding portion 12a disposed on the first housing wall 1212.

[0213] The housing 1211 is used to enclose a space for accommodating the relevant components that realize electrochemical reactions in the battery cell 121.

[0214] The shell wall refers to the physical structure between the various walls that enclose the space forming the shell 1211 and extend away from the enclosed space to the outer surface of the shell 1211.

[0215] The protruding portion 12a is disposed on the first shell wall 1212, meaning that the protruding portion 12a includes the area on the first shell wall 1212 that protrudes beyond other parts of the first shell wall 1212. That is, a portion of the first shell wall 1212 forms the protruding portion 12a, and the specific type of this portion is not limited. For example, it can be part or all of the protrusion 1214 formed on the outer surface of the first shell wall 1212 as described below; it can also be other components in the battery assembly 12 other than the battery cell 121, such as the busbar 122, sampling component 123, etc., as described below, and some or all of these components are located on the protruding portion 12a, and this portion is disposed on the first shell wall 1212; it can also be a combination of the above two situations, for example, the protruding portion 12a includes the aforementioned protrusion 1214, the terminal post 1213 disposed on the protrusion 1214 as described below, and the busbar 122 electrically connected to the terminal post 1213, etc.

[0216] This is beneficial for increasing the volume of the battery cell 121 and for making the space inside the housing 11 adaptable to battery cells 121 with different outer contour shapes. It is also beneficial for battery cells 121 with different outer contour shapes to be arranged more compactly in the housing 11, which is beneficial for improving the energy density of the battery 10.

[0217] In some embodiments, see Figure 6 , Figure 12 , Figure 14 , Figure 15 , Figure 40 and Figure 45 The battery assembly 12 also includes a busbar 122, and the battery cell 121 also includes a terminal post 1213. The terminal post 1213 is disposed on the first housing wall 1212. The busbar 122 is electrically connected to the terminal posts 1213 of the two battery cells 121. The protruding portion 12a includes the busbar 122, and at least a portion of the busbar 122 is located in the receiving space 51a.

[0218] Busbar 122 is used to electrically connect multiple battery cells 121 so that the battery cells 121 can be connected in series or in parallel.

[0219] The terminal 1213 is installed on the housing 1211 and is used to electrically connect with the components that realize electrochemical reactions in the battery cell 121, so as to output or input electrical energy into the battery cell 121 through the terminal 1213.

[0220] The protrusion 12a includes at least a portion of the busbar 122, that is, part or all of the busbar 122 is located in the receiving space 51a.

[0221] This is beneficial to increase the space for arranging the busbar 122 by utilizing the accommodating space 51a, thereby further improving the space utilization rate of the vehicle 100. On the one hand, it is beneficial to increase the number of battery cells 121 that the busbar 122 can electrically connect to, which in turn is beneficial to increasing the capacity of the battery 10. On the other hand, it is beneficial to arrange different battery cells 121 more compactly and regularly in the accommodating box 11, which is beneficial to increasing the energy density of the battery 10.

[0222] It should be noted that the specific structure of the busbar 122 and the methods for realizing the series and parallel connection between battery cells 121 have been applied in related technologies, and will not be elaborated here.

[0223] It is understandable that the pole post 1213 can be flush with the outer surface of the housing 1211, so that the outer surface of the first housing wall 1212 is a complete surface; or, see [reference] Figure 15 The pole post 1213 protrudes from the outer surface of the first shell wall 1212.

[0224] It is understandable that the size of the casing 1211 has a direct impact on the size of the components that realize the electrochemical reaction within the battery cell 121, and thus affects the energy density of the battery cell 121.

[0225] In some embodiments, see Figure 6 , Figure 12 , Figure 14 , Figure 15 The pole post 1213 is at least partially housed in the housing space 51a.

[0226] In other words, part or all of the pole post 1213 is located in the receiving space 51a, while part or all of the housing 1211 is located in the receiving space 51a.

[0227] This allows for the use of the accommodating space 51a to increase the space available for arranging the terminal post 1213, which is beneficial for arranging a larger capacity battery in the vehicle 100; at the same time, it further improves the space utilization rate of the vehicle 100.

[0228] In some embodiments, see Figure 6 , Figures 17 to 22 , Figure 40 and Figure 45 The first shell wall 1212 includes a protrusion 1214, and the protruding portion 12a includes the protrusion 1214, at least a portion of which is located in the receiving space 51a. That is, the protrusion 1214 is part of the first shell wall 1212 and is partially or entirely located in the receiving space 51a.

[0229] By setting the protrusion 1214, it is beneficial to increase the space inside the battery cell 121, to increase the volume inside the battery cell 121 for accommodating the components that carry out electrochemical reactions, and to increase the energy density of the battery cell 121.

[0230] Thus, by having the protrusion 1214 located in the accommodating space 51a, it is beneficial to further increase the space inside the battery cell 121, thereby improving the capacity of the battery 10. At the same time, the support plate makes the structure inside the vehicle 100 more compact and improves the utilization rate of the interior space of the vehicle 100.

[0231] In some embodiments, see Figure 6 , Figure 12 , Figure 14 , Figure 15 , Figures 17 to 20 The protrusion 1214 is provided with a pole post 1213, that is, the pole post 1213 is inserted into the protrusion 1214.

[0232] This is beneficial to improving the utilization efficiency of the space within the protrusion 1214 of the accommodating space 51a, making the arrangement between the battery 10 and the support plate 50 more compact, improving the energy density and space utilization of the battery 10, and increasing the utilization rate of the interior space of the vehicle 100.

[0233] In some embodiments, see Figure 17 , Figure 19 and Figure 20 There are two pole posts 1213 with opposite polarities, and the two pole posts 1213 are located on the same protrusion 1214.

[0234] One terminal 1213 serves as the positive electrode of the battery cell 121, and the other terminal 1213 serves as the negative electrode of the battery cell 121.

[0235] This allows for the provision of mounting positions for the two pole posts 1213 by only manufacturing one protrusion 1214, which helps reduce the manufacturing steps of the first shell wall 1212 and lowers production costs.

[0236] In some embodiments, see Figure 19 and Figure 20 The protrusion 1214 is located at one end of the first shell wall 1212 along the length of the first shell wall 1212.

[0237] The length direction of the first shell wall 1212 refers to the direction in which the largest dimension of the three-dimensional dimensions of the outer contour of the first shell wall 1212 extends when the outer contour shape of the first shell wall 1212 is a cuboid.

[0238] In this way, the area of ​​the first shell wall 1212 located at the other end away from the protrusion 1214 along its length direction is maximized, which facilitates the arrangement of other components with larger outer contour dimensions in the battery 10 in this area, providing convenience for the arrangement of other components in the battery 10. At the same time, it helps to reduce the volume of the battery 10, improve the space utilization rate inside the battery 10, make the battery 10 more compact, and help to increase the total capacity of the battery 10 in the vehicle 100.

[0239] In some embodiments, see Figure 18 There are two pole posts 1213 with opposite polarities, and the two pole posts 1213 are respectively located on two protrusions 1214.

[0240] In this way, on the one hand, it is beneficial to reduce the volume of a single protrusion 1214, making the structure more compact, which is beneficial to reduce the volume of the battery cell 121, thereby allowing more battery cells 121 to be arranged in the battery 10 and increasing the total capacity of the battery 10 in the vehicle 100; on the other hand, it is beneficial to make the two terminals 1213 spaced apart, reducing the risk of short circuit between the two terminals 1213 and improving the safety of the battery cell 121.

[0241] In some embodiments, see Figure 18 The two protrusions 1214 are located at one end of the first shell wall 1212 along its length.

[0242] This allows the first shell wall 1212 between the two protrusions 1214 to form a large flat area. This facilitates the placement of other components with larger outer dimensions in the battery 10 within this area, given a fixed internal volume of the battery 10. It also reduces the volume of the battery 10, improves the internal space utilization, and makes the battery 10 more compact, thus increasing the total capacity of the battery 10 in the vehicle 100.

[0243] In some embodiments, see Figure 17 and Figure 21 The protrusion 1214 is located at the center of the first shell wall 1212 along the length direction of the first shell wall 1212.

[0244] That is, the first center surface 1212a of the first shell wall 1212 along its length direction coincides with the third center surface 1214a of the protrusion 1214 along the length direction of the battery cell 121.

[0245] The first center plane 1212a refers to the reference plane that is perpendicular to the length direction of the first shell wall 1212 and located at half the length of the first shell wall 1212.

[0246] The third center plane 1214a refers to the reference plane that is perpendicular to the length direction of the protrusion 1214 and located at half the length of the protrusion 1214.

[0247] This makes it easier to make the structure of the battery cell 121 symmetrical about the first center plane 1212a, and facilitates the adjustment of the placement direction when multiple battery cells 121121 are arranged in the battery 10, so as to improve the adaptability of the battery cell 121 in the battery 10.

[0248] It should be noted that due to various factors in the manufacturing, assembly, and measurement processes, the first center surface 1212a of the first shell wall 1212 along its length and the third center surface 1214a of the protrusion 1214 along the length of the battery cell 121 cannot be perfectly aligned with the design dimensions after the battery cell 121 is manufactured. Therefore, the actual measurement of whether the first center surface 1212a and the third center surface 1214a coincide is based on a certain preset error range. In other words, the two are considered to coincide if the distance between the first center surface 1212a and the third center surface 1214a along the length of the first shell wall 1212 is within a preset range. The specific value of the preset range is determined according to the design requirements.

[0249] In some embodiments, see Figures 17 to 20 The center position of the first shell wall 1212 along its width direction coincides with the center position of the protrusion 1214 along the width direction of the first shell wall 1212.

[0250] That is, the second center surface 1212b of the first shell wall 1212 along its width direction coincides with the fourth center surface 1214b of the protrusion 1214 along the width direction of the first shell wall 1212.

[0251] See Figure 21 The second center plane 1212b refers to a reference plane that is perpendicular to the width direction of the first shell wall 1212 and located at half the width direction of the first shell wall 1212. The fourth center plane 1214b refers to a reference plane that is perpendicular to the width direction of the first shell wall 1212 and located at half the width direction of the protrusion 1214.

[0252] This further facilitates the formation of a large flat area in the width direction of the first shell wall 1212, making it easier for other components with large outer contour dimensions in the battery 10 to be arranged in this area. This provides convenience for the arrangement of other components in the battery 10. At the same time, it helps to reduce the volume of the battery 10, improve the space utilization rate inside the battery 10, make the battery 10 more compact, and help to increase the total capacity of the battery 10 in the vehicle 100.

[0253] It should be noted that due to various factors in the manufacturing, assembly, and measurement processes, the second center surface 1212b and the fourth center surface 1214b cannot be perfectly aligned with the design dimensions after the battery cell 121 is manufactured. Therefore, the actual measurement of whether the second center surface 1212b and the fourth center surface 1214b are aligned is based on a certain preset error range. In other words, if the distance between the second center surface 1212b and the fourth center surface 1214b along the width direction of the first shell wall 1212 is within a preset range, they can be considered aligned. The specific value of the preset range is determined according to design requirements. For some embodiments, see [reference needed]. Figure 17 , Figure 18 and Figure 20 Two pole posts 1213 are spaced apart along the length of the first shell wall 1212.

[0254] This maximizes the distance between the two protrusions 1214, which helps to form a large flat area in the first shell wall 1212 between the two protrusions 1214. This allows other components with larger outer dimensions in the battery 10 to be arranged in this area, facilitating the arrangement of other components in the battery 10. At the same time, it helps to reduce the volume of the battery 10 and improve the space utilization rate inside the battery 10, thereby improving the space utilization rate inside the vehicle 100.

[0255] In some embodiments, see Figure 19 The two pole posts 1213 are spaced apart along the width direction of the first shell wall 1212.

[0256] The width direction of the first shell wall 1212 refers to the direction perpendicular to the length direction in the three-dimensional dimensions of the outer contour of the first shell wall 1212 when the outer contour shape of the first shell wall 1212 is a cuboid.

[0257] It is understandable that the dimension of the first shell wall 1212 along its width direction is smaller than its dimension along its length direction. The battery 10 has a plurality of battery cells 121. The arrangement of the plurality of battery cells 121 along the width direction is conducive to reducing the maximum dimension of the outer contour formed by the plurality of battery cells 121.

[0258] Thus, the two terminals 1213 are arranged along the width direction of the first shell wall 1212, which helps to shorten the distance between terminals 1213 of different polarities between two adjacent battery cells 121, facilitates the electrical connection between two different adjacent battery cells 121, and thus helps to reduce the size of the battery 10.

[0259] In some embodiments, see Figure 40 and Figure 45 The battery cell 121 also includes an electrode assembly 1215, which is housed in the housing 1211. A portion of the first housing wall 1212 is recessed to form a relief groove 1212c. The relief groove 1212c is located on the side of the protrusion 1214 near the electrode assembly 1215, and a portion of the electrode assembly 1215 is located in the relief groove 1212c.

[0260] The housing 1211 provides a housing space 51a for the electrode assembly 1215 and serves to protect it. At the same time, the housing 1211 is used for the movement of electrolyte so that an electrochemical reaction can occur between the electrolyte and the electrode assembly 1215.

[0261] The first shell wall 1212 is provided with a clearance area. The clearance area is recessed on the side facing the electrode assembly 1215 to form a clearance groove 1212c, and protrudes on the side away from the electrode assembly 1215 to form a protrusion 1214. The protrusion 1214 and the clearance groove 1212c are correspondingly arranged.

[0262] A portion of the electrode assembly 1215 is located in the clearance groove 1212c. This allows the first shell wall 1212 to be as close as possible to the electrode assembly 1215, given a fixed size. This effectively reduces the volume within the shell 1211 while allowing as much of the electrode assembly 1215 as possible to extend into the clearance groove 1212c. This helps reduce redundant volume within the battery cell 121, making the space within the battery cell 121 more compact. Consequently, it helps reduce the overall volume and outer dimensions of the battery cell 121, thereby increasing the number of battery cells 121 that can be accommodated within the battery 10 and improving the energy density and space utilization of the battery 10.

[0263] It is understood that the battery cell 121 has at least a partial mounting cavity for placing the electrode assembly 1215, and the mounting cavity is connected to the clearance groove 1212c.

[0264] In some embodiments, see Figure 15 , Figure 40 and Figure 45 The electrode assembly 1215 includes a body 1216 and a tab 1217. The tab 1217 is disposed on one side edge of the body 1216 and electrically connected to the body 1216. At least a portion of the tab 1217 is located in the clearance groove 1212c.

[0265] The main body 1216, i.e., the bare cell, is formed by stacking or winding multiple electrode sheets. The tab 1217 forms the positive or negative electrode in the electrode assembly 1215.

[0266] By having part or all of the tab 1217 located in the clearance groove 1212c, it is beneficial to further increase the volume of the main body 1216 in the battery cell 121, thereby improving the energy density of the battery cell 121.

[0267] Understandably, the tab 1217 protrudes from one side of the surface of the main body 1216.

[0268] It is understandable that the main component 1216 directly participates in the electrochemical reaction, and its size is directly related to the capacity of the battery cell 121.

[0269] In some embodiments, see Figure 15 , Figure 40 and Figure 45 At least a portion of the tab 1217 is located in the receiving space 51a, which helps to increase the space for arranging the tab 1217, thereby allowing more space to be arranged for the main body 1216, which helps to increase the capacity of the battery cell 121.

[0270] In some embodiments where the pole post 1213 is provided Figure 40 and Figure 45 The electrode assembly 1215 also includes an adapter piece 1218, through which the tab 1217 and the post 1213 are electrically connected, and at least a portion of the adapter piece 1218 is located in the receiving space 51a.

[0271] The adapter piece 1218 is used to electrically connect the pole post 1213 and the tab 1217 to meet the electrical connection requirements between pole posts 1213 and tabs 1217 of different sizes and specifications.

[0272] Thus, with part or all of the adapter piece 1218 located in the accommodating space 51a, it is beneficial to increase the space for arranging the adapter piece 1218, thereby allowing more space to be arranged for the main body 1216, which is beneficial to increasing the capacity of the battery cell 121.

[0273] It is understandable that in order to accommodate the charging and discharging functions of the battery cell 121, other auxiliary components are also provided in the battery 10, and the arrangement of these auxiliary components also has an important impact on the better utilization of the space within the housing space 51a.

[0274] In some embodiments, see Figure 14 , Figure 15 , Figure 16 , Figure 23 , Figure 38 , Figure 39 , Figure 43 and Figure 44 The battery assembly 12 also includes a sampling member 123, at least a portion of which is housed in the housing space 51a.

[0275] The sampling component 123 is used to acquire parameter information such as voltage and temperature of various components inside the battery 10, such as battery cells 121, and transmit the acquired parameter information to the battery management system 124 (BMS) so that the battery management system 124 can reasonably implement different control strategies to enable the battery 10 to charge and discharge safely and efficiently.

[0276] In other words, part or all of the sampling component 123 is located in the accommodating space 51a.

[0277] This allows for an increase in the space available for arranging the sampling components 123 by utilizing the accommodating space 51a, which in turn increases the overall volume of the battery 10 and further enhances the capacity of the battery in the vehicle 100.

[0278] It should be noted that the specific structure of the sampling component 123 and the distance for sampling different parameter information have been applied in related technologies, and will not be elaborated here.

[0279] In some embodiments, see Figure 23 The battery assembly 12 also includes a battery management system 124, at least a portion of which is housed in the housing space 51a.

[0280] The battery management system 124 is used to manage and control the various electrical components in each battery 10, monitor the operating status of the battery 10, and adopt appropriate control strategies according to its operating status to prevent the battery 10 from overcharging and over-discharging, so as to extend the service life of the battery 10.

[0281] This is beneficial to increase the space for arranging the battery management system 124 by utilizing the accommodating space 51a, which in turn is beneficial to increase the overall volume of the battery 10, further beneficial to improve the capacity accommodating space 51a support plate of the battery 10 in the vehicle 100, improve the space utilization rate of the space inside the vehicle 100, and make the part of the battery 10 located outside the accommodating space 51a more regular in shape.

[0282] In some embodiments, see Figure 23 The battery assembly 12 also includes a relay 125, at least a portion of which is housed in the housing space 51a.

[0283] When the battery 10 in the vehicle 100 needs to be charged or discharged, the relay 125 responds to the command of the electrical system to open or close the connection between the battery 10 and other electrical components in the vehicle 100, so as to realize the transmission or interruption of electrical energy.

[0284] This is beneficial to increase the space for arranging the relay 125 by utilizing the accommodating space 51a, which in turn is beneficial to increase the overall volume of the battery 10, further beneficial to improve the capacity of the battery 10 in the vehicle 100, improve the space utilization rate of the space inside the vehicle 100, and make the part of the battery 10 located outside the accommodating space 51a more regular in shape.

[0285] In some embodiments, see Figure 23 The battery assembly 12 also includes a high-voltage power distribution unit 126, at least a portion of which is housed in the housing space 51a.

[0286] The high-voltage power distribution unit 126 is used to monitor the high-voltage connection status and insulation status of the battery 10 in real time, so as to manage the high-voltage power safety in the battery 10.

[0287] This is beneficial to increase the space for arranging the high-voltage power distribution unit 126 by utilizing the accommodating space 51a, which in turn is beneficial to increase the overall volume of the battery 10, further beneficial to increase the capacity of the battery 10 in the vehicle 100, the accommodating space 51a support plate, improve the space utilization rate of the space inside the vehicle 100, and make the part of the battery 10 located outside the accommodating space 51a more regular in shape.

[0288] In some embodiments, see Figure 23 The battery assembly also includes high and low voltage wiring harnesses 127, at least a portion of which are housed in housing space 51a.

[0289] The high and low voltage wiring harness 127 is used to electrically connect various components in the battery assembly 12 to transmit high and low voltage currents and realize the transmission of electrical energy and control signals.

[0290] This allows for an increase in the space available for arranging the high and low voltage wiring harnesses 127 by utilizing the accommodating space 51a, reducing the bending of the high and low voltage wiring harnesses 127, increasing the overall volume of the battery 10, and further improving the capacity of the battery 10 in the vehicle 100.

[0291] In some embodiments, see Figure 21 The length of the battery cell 121 is not less than 350 mm (millimeters), that is, L1≥350 mm. This is conducive to the electrochemical reaction of the electrode components and electrolyte in the battery cell 121, which can store or release sufficient electrical energy, and to the total electrical energy in the battery 10 meeting the demand.

[0292] The length of the battery cell 121 can be any value, such as 400mm, 500mm, 600mm, 700mm, 800mm, 900mm, 1000mm, 1200mm, 1500mm, etc.

[0293] The specific method for measuring the length of the battery cell 121 is not limited. For example, at room temperature of 25°C (Celsius), the length of the battery cell 121 can be obtained by placing the main scale and vernier scale of a vernier caliper against both ends of the battery cell 121 along the length direction and reading the data shown on the vernier caliper.

[0294] In some embodiments, see Figure 21 The width of the battery cell 121 ranges from 5mm to 50mm, i.e., 5mm≤L2≤50mm. This makes the size of the battery cell 121 easy to handle and better fits the size of the housing 11 of different sizes.

[0295] The specific value of the dimension of the battery cell 121 along the width direction is not limited, such as 5mm, 20mm, 30mm, 35mm, 40mm, 50mm, etc.

[0296] The specific method for measuring the width of the battery cell 121 is not limited. For example, in an environment with a room temperature of 25°C (Celsius), the width of the battery cell 121 can be obtained by placing the main scale and vernier scale of a vernier caliper against both ends of the battery cell 121 along the width direction and reading the data shown on the vernier caliper.

[0297] In some embodiments, see Figure 22 The height of the battery cell 121 ranges from 80mm to 200mm, i.e., 80mm≤L3≤200mm. This makes the size of the battery cell 121 easy to handle and better fits the size of the housing 11 of different sizes.

[0298] The specific value of the dimension of the battery cell 121 along the height direction is not limited, such as 80mm, 100mm, 120mm, 150mm, 180mm, 200mm, etc.

[0299] The specific method for measuring the height of the battery cell 121 is not limited. For example, in an environment with a room temperature of 25°C (Celsius), place the battery cell 121 on the measurement reference plane, so that the height direction of the battery cell 121 is perpendicular to the measurement reference plane. Align the zero mark of the ruler with one end of the battery cell 121 along the height direction, and read the mark that is aligned with the other end of the battery cell 121 along the height direction to obtain the height of the battery cell 121.

[0300] In some embodiments, see Figure 12 The height of the protruding portion 12a within the accommodating space 51a ranges from 2 mm to 10 mm. That is, see [reference needed]. Figure 12 , 2mm≤H1≤10mm.

[0301] The height of the protruding portion 12a refers to the dimension of the protruding portion 12a along the height direction of the battery 10.

[0302] This improves the space utilization rate within the accommodating space 51a.

[0303] The specific value of the height of the protruding part 12a is not limited, such as 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc.

[0304] In some embodiments, see Figure 2 , Figure 7 , Figures 24 to 35 The vehicle 100 also includes a seat 20, which is located on the side of the support plate 50 where a raised portion 51 is formed.

[0305] Seat 20 is used by the occupants of vehicle 100 for sitting and placing items.

[0306] In other words, the interior space 100a located on the side of the support plate 50 with the raised portion 51 is the passenger compartment in the vehicle 100. In a passenger car, the passenger compartment has the largest volume of space in the vehicle 100. Correspondingly, the support plate 50 has the largest size, and the area that can be used to arrange the battery 10 is also the largest, which is conducive to increasing the capacity of the battery 10 in the vehicle 100.

[0307] This is beneficial for increasing the volume of the battery 10 inside the vehicle 100, thereby increasing the capacity of the battery 10 and improving the driving range of the vehicle 100. At the same time, it is beneficial for the flat walls of the housing 11 to face the ground, making the bottom surface of the vehicle 100 flatter, reducing the drag coefficient of the vehicle 100 and increasing the ground clearance of the vehicle 100. This reduces the possibility of the raised part 51 increasing wind resistance and collision with foreign objects on the road surface during the driving process, which could lead to damage to the battery 10.

[0308] The drag coefficient is a parameter used to describe the air resistance an object experiences in a gas stream. Its value reflects the degree to which the object's shape affects gas flow. A higher drag coefficient indicates greater air resistance encountered by the object during movement. Therefore, the drag coefficient directly affects a vehicle's energy consumption per 100 kilometers of travel.

[0309] Ground clearance refers to the distance between the ground and a rigid object under the vehicle body while the vehicle is in motion. Its size directly affects the vehicle's passability.

[0310] In some embodiments, see Figures 24 to 35In the projection perpendicular to the height direction of the vehicle 100, part or all of the projection of the raised portion 51 is located within the projection range of the seat 20.

[0311] In other words, at least part of the raised portion 51 is located in the space below the contact surface with the seat 20 when the occupant is seated.

[0312] It is understandable that when an occupant is seated in seat 20, due to the occupant's sitting posture, the space below the contact surface with seat 20, including seat 20 itself and the space below seat 20, is not accessible to the occupant's limbs, or is difficult to access.

[0313] In this way, the raised section 51 utilizes the space under the seat 20, reducing the chance of the occupant touching the raised section 51 during the ride, thereby reducing the encroachment of the raised section 51 on the occupant's normal activity space, improving the user experience, and increasing the space utilization rate inside the vehicle 100.

[0314] It is understandable that there can be multiple seats 20, and the position of the raised portion 51 is adapted to the arrangement relationship between the multiple seats 20.

[0315] In some embodiments, see Figures 24 to 26 , Figure 29 , Figure 33 The number of seats 20 is at least two, and a first gap 20a is formed between two adjacent seats 20 along the width direction of the vehicle 100. The raised portion 51 includes a first raised portion 51b, and part or all of the first raised portion 51b is located in the first gap 20a.

[0316] The width direction of vehicle 100 refers to the direction in which the dimension of vehicle 100 is perpendicular to the length direction and the direction of gravity.

[0317] The direction of gravity is vertical.

[0318] It is understandable that when the occupant is seated in seat 20, due to the occupant's sitting posture, it is difficult for the occupant's legs to enter the first gap 20a.

[0319] In this way, the first raised portion 51b can utilize the space in the first gap 20a, which increases the volume of the battery 10 while reducing the probability of the occupant touching the first raised portion 51b during the ride, reducing the interference of the first raised portion 51b on the occupant's normal activities, and improving the space utilization rate inside the vehicle 100.

[0320] It is understandable that other equipment in the vehicle 100, such as armrests, car refrigerators, and storage boxes, can also be arranged in the first gap 20a to improve the space utilization of the vehicle and enhance the user experience.

[0321] In some embodiments, a portion of the projection of the first bulge 51b lies within the projection range of the seat 20, while another portion lies within the first gap 20a.

[0322] In some embodiments, see Figure 24 , Figure 26 , Figure 33 The number of seats 20 is multiple, and the multiple seats 20 are arranged in at least two rows along the length direction of the vehicle 100. The first raised portion 51b extends along the length direction of the vehicle 100 to the bottom of the adjacent row of seats 20.

[0323] The length direction of vehicle 100 refers to the direction of the dimension with the largest value among the three-dimensional dimensions of vehicle 100. Generally, the length direction of vehicle 100 is also the forward or backward direction when vehicle 100 is traveling in a straight line.

[0324] This makes it easier to increase the volume of the first raised portion 51b, which in turn makes it easier to increase the volume of the accommodating space 51a in the first raised portion 51b, which in turn makes it easier to increase the volume of the battery 10 and increase the capacity of the battery 10.

[0325] In some embodiments, see Figures 30 to 35 The raised portion 51 includes a second raised portion 51c, which extends along the length direction of the vehicle 100 and is located on one side of the support plate seat 20 along the width direction of the vehicle 100.

[0326] This reduces the interference of the second bulge 51c with the occupant's leg and foot movements, improving the occupant's user experience.

[0327] In some embodiments, see Figures 30 to 35 There are two second bulges 51c, and the two second bulges 51c are located at one end of the support plate 50 along the width direction of the vehicle 100, and the seat 20 is located between the two second bulges 51c.

[0328] In other words, the seat 20 is located in the area between the two second bulges 51c.

[0329] This allows for greater leg and foot space for occupants, improving their user experience; at the same time, the arrangement of the second bulge 51c effectively utilizes the space along the width of the vehicle 100.

[0330] In some embodiments, see Figures 30 to 35 The second raised portion 51c extends along the length direction to both ends of the battery 10 along the length direction of the vehicle 100, so as to further increase the capacity of the battery 10.

[0331] In some embodiments, the second bulge 51c is spaced apart from the seat 20 along the width direction of the vehicle 100.

[0332] This increases the leg and foot space for passengers, improving the user's riding experience.

[0333] In some embodiments, see Figure 32 and Figure 34 The second raised portion 51c is located below the seat 20.

[0334] This helps to reduce the size of the support plate 50 in the width direction, making the structure of the vehicle 100 more compact.

[0335] In some embodiments, see Figures 27 to 29 The raised portion 51 includes a third raised portion 51d, which extends along the width direction of the vehicle 100. There are multiple seats 20, which are divided into at least two rows spaced apart along the length direction of the vehicle 100. At least a portion of the third raised portion 51d is located below the seats 20 in the same row.

[0336] In this way, the third hump 51d makes better use of the space under the seat 20 along the width direction of the vehicle 100. At the same time, the third hump 51d can reduce the encroachment on the space between the two adjacent rows of seats 20, reduce interference with the activities of the occupants, and improve the occupant experience.

[0337] In some embodiments where a first gap 20a is provided, a portion of the third bulge 51d is located below the seat 20, and another portion is located in the first gap 20a.

[0338] This allows the third bulge 51d to make better use of the space under the seat 20 and the space in the first gap 20a, which helps to improve the space utilization rate of the battery 10 within the vehicle 100 and increase the capacity of the battery 10.

[0339] It is understood that multiple first gaps 20a are provided between the multiple seats 20 spaced apart along the width direction of the vehicle 100, and the third bulge 51d extends along the width direction of the vehicle 100 and passes through all the first gaps 20a and is located below each seat 20 in the same row to improve space utilization.

[0340] In some embodiments, see Figure 2 , Figure 7 , Figure 24 , Figure 25 , Figure 29 , Figure 32 and Figure 34The seat 20 includes a seat 21, at least a portion of which forms a second gap 20b with the support plate 50 along the height direction of the vehicle 100. At least a portion of the raised portion 51 is located in the second gap 20b and is spaced apart from the seat 21 along the height direction of the vehicle 100.

[0341] Seat 21 is for passengers to sit on in order to support the weight of the passengers.

[0342] In this way, the probability of damage to the raised part 51 due to the pressure of the occupant sitting on it caused by direct contact between the raised part 51 and the seat 21 can be reduced.

[0343] It is understandable that a portion of the bottom surface of the seat 21 may form a second gap 20b with the support plate 50 along the height direction of the vehicle 100, while another portion may be in contact with the support plate 50; or the entire bottom surface of the seat 21 may form a second gap 20b with the support plate 50 along the height direction of the vehicle 100, that is, the seat 21 and the support plate 50 may be completely spaced apart along the height direction of the vehicle 100.

[0344] The specific method of forming the second gap 20b is not limited.

[0345] For example, see Figure 24 , Figure 25 , Figure 27 , Figure 32 and Figure 34 The seat 20 includes a leg 23, the seat 21 and the support plate 50 are spaced apart in the vertical direction to form a second gap 20b, and the leg 23 is connected between the seat 21 and the support plate 50.

[0346] This facilitates the spacing between the seat 21 and the raised portion 51, making the seat 21 more regular in shape and easier to place; at the same time, it allows the occupant to extend their feet into the second gap 20b, allowing the occupant to stretch out their sitting posture and improving riding comfort.

[0347] It is understandable that the connection position between the support leg 23 and the support plate 50 is not limited; it can be located on the raised portion 51 or in other areas of the support plate 50 other than the raised portion 51.

[0348] In some embodiments, see Figure 24 , Figure 25 , Figure 27 , Figure 32 and Figure 34 The number of legs 23 is multiple, and the multiple legs 23 are spaced apart along the width direction of the vehicle 100. Part or all of the raised portion 51 is located between two adjacent legs 23 along the width direction of the vehicle 100.

[0349] This facilitates the arrangement of the raised portion 51, utilizing the space between the two legs 23, which helps to improve the space utilization rate of the battery 10 in the interior space of the vehicle 100 and increase the capacity of the battery 10.

[0350] Understandably, the seat 21 includes a cushioning pad 211, which is made of a material such as sponge that can undergo elastic deformation in order to improve the occupant's riding comfort.

[0351] Understandably, it is necessary to constrain the shape of the cushioning pad 211 in order to support the structure of the seat 21.

[0352] In some embodiments with a cushioning pad 211, the raised portion 51 is embedded in the cushioning pad 211 to support the seat 21 along the height direction of the vehicle 100.

[0353] In other words, the raised portion 51 forms at least part of the structure that supports the cushioning pad 211. This simplifies the structure of the seat 20, improves the utilization of the interior space of the seat 20, and reduces production costs.

[0354] It is understood that the seat 21 includes a frame 212, which is inserted into and conforms to the cushioning pad 211 to constrain the shape of the cushioning pad 211.

[0355] In some embodiments, see Figure 3 and Figure 8 The frame 212 is connected to the raised portion 51 to form a force transmission path of the buffer pad 211, frame 212 and raised portion 51, thereby transferring the weight of the occupant to the support plate 50.

[0356] The relative structural relationship between the support plate 50 and the battery 10 is not limited. The present disclosure provides the following two embodiments of the battery 10 and the support plate 50.

[0357] Implementation Method 1

[0358] See Figures 7 to 12 , Figures 36 to 39 The housing 11 has one side open to form a first opening 11c, and the support plate 50 is covered on the first opening 11c to jointly form a housing cavity 11a, and the battery assembly 12 is disposed in the housing cavity 11a.

[0359] In other words, when the battery 10 is not installed in the vehicle 100, the battery component 12 in the battery 10 is directly exposed to the outside world on the side facing the first opening 11c; when the battery 10 is installed in the vehicle 100, the battery component 12 is separated from the vehicle interior space 100a only by the support plate 50.

[0360] This simplifies the structure of the vehicle 100, making the arrangement between the support plate 50 and the battery 10 more compact. Given a fixed internal space volume for the vehicle 100, this increases the capacity of the battery 10. At the same time, it facilitates the direct access to the battery assembly 12 for maintenance after the battery 10 is removed from the vehicle 100, through the first opening 11c.

[0361] Understandably, the support plate 50 completely covers the first opening 11c.

[0362] Understandably, with battery 10 installed in vehicle 100, the ease of maintenance of battery 10 needs to be considered.

[0363] In some embodiments, see Figures 37 to 39 The raised portion 51 includes a raised body 511 and a first sealing cover 512. The raised body 511 is provided with a through hole 511a, which communicates with the receiving space 51a. The first sealing cover 512 is detachably connected to the raised body 511 to seal the first through hole 511a.

[0364] Thus, when the battery 10 needs to be inspected and maintained, the battery assembly 12 located in the housing space 51a can be inspected from the vehicle interior space 100a through the first opening 11c and the first through hole by removing the first sealing cover 512, without having to remove the battery 10. This increases the working space for maintenance personnel and improves the convenience of maintenance work.

[0365] The specific number of the first through hole 511a is not limited; it can be one or more.

[0366] Understandably, it is necessary to reduce the likelihood of foreign objects entering the receiving cavity 11a through the seam between the first sealing cover 512 and the raised body 511, thus affecting the operation of the battery assembly 12.

[0367] In some embodiments, see Figure 38 and Figure 39 The raised portion 51 also includes a first sealing member 513, which is arranged around the periphery of the first through hole 511a and sandwiched between the raised body 511 and the first sealing cover 512 to seal the raised body 511 and the first sealing cover 512.

[0368] The first seal 513 can undergo elastic deformation. When the first seal 513 is sandwiched between the raised body 511 and the first sealing cover 512, the first seal 513 reduces the seam space between the raised body 511 and the first sealing cover 512 and the contact area with the first seal 513 through elastic deformation. This reduces the probability of foreign objects entering the receiving cavity 11a and affecting the operation of the battery 10, extends the service life of the battery 10, and is beneficial to the safety of the battery 10.

[0369] The specific material of the first seal 513 is not limited, such as silicone, industrial rubber, etc.

[0370] The specific method by which the first sealing cover is detachably connected to the raised body 511 is not limited.

[0371] In some embodiments, the first sealing cap 512 is mounted to the raised body 511 by threaded fasteners.

[0372] Threaded fasteners are fasteners such as screws, bolts, and studs that achieve threaded connections.

[0373] Thus, using threaded fasteners facilitates disassembly and improves the connection strength between the first sealing cover 512 and the raised body 511.

[0374] It is understandable that one of the raised body 511 and the first closed cover 512 is provided with a through hole and the other with a threaded hole, through which the threaded fastener passes to achieve a threaded connection with the thread in the threaded hole.

[0375] In some embodiments, the first closure cover 512 is slidably snapped onto the raised body 511.

[0376] In other words, one of the first closing cover 512 and the raised body 511 is provided with a groove, and a part of the other can be embedded in the groove, so that the two can slide relative to each other.

[0377] Thus, by adopting a sliding mechanism, the first sealing cover 512 can be opened or closed more quickly, improving the convenience of maintenance.

[0378] In some embodiments, the first closure cover 512 is hinged to the raised body 511.

[0379] In other words, the first sealing cover 512 can rotate relative to the raised body 511 by means of hinge, so that the first sealing cover 512 opens or closes the first through hole 511a.

[0380] Thus, by using a rotating mechanism, the first sealing cover 512 can be opened or closed more quickly, improving the convenience of maintenance.

[0381] In some embodiments, see Figure 39 The battery 10 includes a temperature control component 14, which is sandwiched between the support plate 50 and the battery component 12.

[0382] The temperature control component 14 has a flow channel and a temperature control medium inside. The temperature control medium can flow in the flow channel to transfer heat from one part of the temperature control component 14 to another part, thereby achieving the purpose of adjusting the temperature of the object in contact with the temperature control component 14.

[0383] In this way, the temperature control component 14 absorbs the heat generated during the operation of the battery component 12, thereby reducing the operating temperature of the battery component 12 and improving the safety of the battery 10. At the same time, it reduces the heat transferred from the battery component 12 to the support plate 50 and radiated into the vehicle interior space 100a during operation. It can better utilize the advantage of the large area of ​​the support plate 50, increase the contact area between the temperature control component 14 and the battery component 12, and improve the temperature control effect.

[0384] It should be noted that the specific structure and heat exchange principle of the temperature control component 14 have been applied in related technologies, and will not be elaborated here.

[0385] It is understandable that the position of the temperature control component 14 relative to the battery component 12 needs to be fixed so that the temperature control effect of the temperature control component 14 can be fully utilized.

[0386] In some embodiments, see Figure 38 and Figure 39 The battery 10 includes a first adhesive layer 13, which is adhered between the support plate 50 and the outer surface of the temperature control component 14.

[0387] This fixes the relative position between the temperature control component 14 and the support plate 50, reducing the chance of friction damage caused by relative movement between the two.

[0388] In some embodiments, see Figure 38 and Figure 39 The battery 10 includes a third adhesive layer 16, which is adhered between the temperature control component 14 and the outer surface of the battery component 12.

[0389] This fixes the relative position between the temperature control component 14 and the battery component 12, reducing the chance of friction damage caused by relative movement between them.

[0390] In an embodiment where the protrusion 1214 is provided and at least a portion of the protrusion 1214 is located in the receiving space 51a, see [reference]. Figure 12 The height of protrusion 1214 does not exceed 77% of the height of raised portion 51. That is, H4 / H2 ≤ 77%.

[0391] In this way, on the one hand, it is beneficial to keep the protrusion 1214 and the receiving space 51a apart along the height direction of the battery 10, so as to reduce the probability of damage caused by direct contact between the two, and also facilitate the arrangement of other components of the battery assembly 12 in the receiving space 51a; on the other hand, it allows the thickness of the raised portion 51 to better protect the protrusion 1214.

[0392] In some embodiments, see Figure 12 The height dimension of the protrusion 1214 accounts for 21% to 53% of the height dimension of the raised portion 51.

[0393] This further ensures that the size of the accommodating space 51a meets the requirements for arranging other components of the battery assembly 12; and further helps to ensure that the raised portion 51 has sufficient strength to protect the protrusion 1214.

[0394] In some embodiments where the pole post 1213 is provided, see [reference]. Figure 12 At least two battery cells 121 have their terminals 1213 located in the same housing space 51a.

[0395] This facilitates the electrical connection of the terminals 1213 of different battery cells 121 within a single accommodating space 51a, making the structure of the battery 10 more compact.

[0396] In some embodiments, see Figure 38 and Figure 40 The vehicle 100 also includes a second insulating member 18, which is disposed on the inner wall of the accommodating space 51a.

[0397] In this way, by utilizing the insulating properties of the second insulating member 18, the risk of charge transfer between the battery assembly 12 and the inner wall of the accommodating space 51a can be reduced, thereby reducing the risk of short circuits and other problems occurring in the battery 10 during use.

[0398] The specific material of the second insulating element 18 is not limited, such as rubber.

[0399] In some embodiments, see Figure 38 and Figure 40 The battery assembly 12 includes a battery cell 121, and the battery cell 121 includes a terminal post 1213. The second insulating member 18 is disposed opposite to the terminal post 1213.

[0400] In this way, the probability of the terminal post 1213 coming into contact with the support plate 50 due to relative movement between the battery assembly 12 and the support plate 50 can be reduced, thereby reducing the risk of short circuit of the battery cell 121 due to contact between the terminal post 1213 and the support plate 50.

[0401] The second insulating member 18 is positioned opposite to the pole post 1213, meaning that there are no other components in the vehicle 100 between the second insulating member 18 and the pole post 1213.

[0402] In some embodiments, see Figure 38 The battery assembly 12 also includes a busbar 122, at least a portion of which is located in the receiving space 51a. The distance between the inner wall of the receiving space 51a and the busbar 122 along a first direction is not less than 1% of the dimension of the receiving space 51a along the first direction, which is perpendicular to the bulge direction of the raised portion 51.

[0403] This helps to reduce the probability of the busbar 122 coming into contact with the inner wall of the accommodating space 51a, and reduces the probability of a short circuit due to the busbar 122 coming into contact with the support plate 50.

[0404] The first direction can be any direction perpendicular to the bulge direction of the raised portion 51, such as the length direction of the battery 10, the width direction of the battery 10, etc.

[0405] In some embodiments, the distance between the inner wall of the accommodating space 51a and the manifold 122 along the first direction is in the range of 2% to 10% of the size of the accommodating space along the first direction.

[0406] This further helps to reduce the probability of the busbar 122 coming into contact with the inner wall of the accommodating space 51a.

[0407] Implementation Method 2

[0408] See Figures 2 to 6 , Figures 13 to 16 , Figures 41 to 44 The container 11 includes a first container wall 111, which is located on the side of the container 11 facing the support plate 50, and a portion of the first container wall 111 extends into the receiving space 51a.

[0409] In other words, the interior space 100a and the battery assembly 12 are separated by the first box wall 111 and the support plate 50. The first box wall 111 itself is a component of the battery 10. Even when the battery 10 is removed from the vehicle 100, the first box wall 111 is still located on the battery 10.

[0410] Thus, on the one hand, during the separate transport of battery 10, the first box wall 111 can protect battery assembly 12; on the other hand, it reduces the probability of battery assembly 12 coming into contact with support plate 50, and reduces the probability of battery 10 leaking electricity and causing adverse effects on other parts and personnel in vehicle 100.

[0411] In some embodiments, see Figures 13 to 16 , Figures 41 to 44 The housing 11 includes a housing body 112 and a housing cover. The first housing wall 111 forms the housing cover. One side of the housing body 112 is open to form a second opening 112a. The housing cover is placed on the second opening 112a to form a housing cavity 11a with the housing body 112. The battery assembly 12 is placed in the housing cavity 11a.

[0412] Thus, the housing 11 is formed by splicing the housing 112 and the housing cover, which makes it easy to disassemble the housing 11 as needed for inspection and maintenance of the battery assembly 12.

[0413] Understandably, the enclosure 112 and the cover are detachably connected so that they can be selectively connected and separated.

[0414] In some embodiments, see Figures 42 to 44 The first box wall 111 includes a box wall body 1112 and a second sealing cover 1113. The box wall body 1112 is provided with a through second through hole 1112a, which communicates with the receiving cavity 11a. The second sealing cover 1113 is detachably connected to the box wall body 1112 to seal the second through hole 1112a.

[0415] Thus, with the battery 10 separated from the vehicle 100, the battery assembly 12 located in the receiving cavity 11a can be inspected and maintained simply by removing and installing the second sealing cover 1113, through the second through hole 1112a, thereby improving the convenience and efficiency of inspection and maintenance.

[0416] The specific number of the second through hole 1112a is not limited; it can be one or more.

[0417] Understandably, it is necessary to reduce the likelihood of foreign objects entering the receiving cavity 11a through the seam between the second sealing cover 1113 and the box wall body 1112 and affecting the operation of the battery assembly 12.

[0418] In some embodiments, see Figures 42 to 44 The box cover also includes a second sealing element 1114, which is arranged around the periphery of the second through hole 1112a and sandwiched between the box wall body 1112 and the second sealing cover 1113 to seal the box wall body 1112 and the second sealing cover 1113.

[0419] The second seal 1114 can undergo elastic deformation. When the second seal 1114 is sandwiched between the housing body 1112 and the second sealing cover 1113, the elastic deformation of the second seal 1114 reduces the seam space between the housing body 1112 and the second sealing cover 1113 and the contact area of ​​the second seal 1114, thereby reducing the probability of foreign objects entering the receiving cavity 11a and affecting the operation of the battery assembly 12, extending the service life of the battery 10, and improving the safety of the battery 10.

[0420] The specific material of the second seal 1114 is not limited, such as silicone, industrial rubber, etc.

[0421] The specific method by which the second sealing cover is detachably connected to the box wall body 1112 is not limited.

[0422] In some embodiments, the second sealing cover 1113 is mounted to the box wall body 1112 by threaded fasteners.

[0423] Thus, using threaded fasteners facilitates disassembly and improves the connection strength between the second sealing cover 1113 and the box wall body 1112.

[0424] It is understandable that one of the box wall body 1112 and the second sealing cover 1113 is provided with a through hole and the other is provided with a threaded hole, and the threaded fastener passes through and achieves threaded connection with the thread in the threaded hole.

[0425] In some embodiments, the second sealing cover 1113 is slidably snapped onto the box wall body 1112.

[0426] In other words, one of the second sealing cover 1113 and the box wall body 1112 is provided with a sliding groove, and a part of the other can be embedded in the sliding groove, so that the two can slide relative to each other.

[0427] Thus, by adopting a sliding mechanism, the second sealing cover 1113 can be opened or closed more quickly, improving the convenience of maintenance.

[0428] In some embodiments, the second sealing cover 1113 is hinged to the box wall body 1112.

[0429] In other words, the second sealing cover 1113 can rotate relative to the box wall body 1112 by means of hinge, so that the second sealing cover 1113 opens or closes the first through hole 511a.

[0430] Thus, by using a rotating mechanism, the second sealing cover 1113 can be opened or closed more quickly, improving the convenience of maintenance.

[0431] Understandably, with the battery 10 installed inside the vehicle 100, it needs to be easy to inspect and maintain the battery 10.

[0432] In some embodiments, see Figures 42 to 43 The raised portion 51 includes a raised body 511 and a first sealing cover 512. The raised body 511 is provided with a through first through hole 511a, which communicates with the receiving space 51a. The first sealing cover 512 is detachably connected to the raised body 511 to seal the first through hole 511a. The second through hole 1112a is arranged opposite to the first through hole 511a.

[0433] Thus, with the first sealing cover 512 and the second sealing cover 1113 removed, the vehicle interior space 100a, the receiving space 51a, and the receiving cavity 11a are interconnected, and the receiving space 51a and the receiving cavity 11a are arranged opposite to each other. This facilitates maintenance personnel to directly perform maintenance work on the battery assembly 12 from the vehicle interior space 100a without removing the battery 10 from the vehicle 100, thereby improving the convenience and efficiency of maintenance work. In some embodiments, in the projection plane perpendicular to the direction opposite to the second through hole 1112a and the first through hole 511a, the projection of the second through hole 1112a is located within the projection range of the first through hole 511a. This facilitates the disassembly and assembly of the second sealing cover 1113 and the box wall body 1112 through the first through hole 511a.

[0434] In some embodiments, see Figure 43 and Figure 44 The battery 10 includes a temperature control component 14, which is sandwiched between the first housing wall 111 and the battery assembly 12.

[0435] In this way, the temperature control component 14 absorbs the heat generated during the operation of the battery component 12, thereby reducing the operating temperature of the battery component 12 and improving the safety of the battery 10. At the same time, the temperature control component 14 can directly radiate some of the heat to the outside through the wall of the housing 11, increasing the heat dissipation area and improving the temperature control effect.

[0436] In some embodiments, see Figure 43 and Figure 44 The battery 10 includes a second adhesive layer 15, which is adhered between the first housing wall 111 and the outer surface of the temperature control component 14.

[0437] This fixes the relative position between the temperature control component 14 and the first box wall 111, reducing the chance of friction damage caused by relative movement between the two.

[0438] In some embodiments, see Figure 43 and Figure 44The battery 10 includes a third adhesive layer 16, which is adhered between the temperature control component 14 and the outer surface of the battery component 12.

[0439] This fixes the relative position between the temperature control component 14 and the battery component 12, reducing the chance of friction damage caused by relative movement between them.

[0440] In some embodiments, see Figures 13 to 16 , Figures 41 to 44 A portion of the first housing wall 111 protrudes to form a boss 1111, at least a portion of the boss 1111 extends into the receiving space 51a, and the side of the boss 1111 facing away from the receiving space 51a forms a receiving portion 11b, a portion of the battery assembly 12 is located in the receiving portion 11b.

[0441] Thus, by using the receiving portion 11b, a portion of the battery assembly 12 is located in the receiving space 51a, which protects the battery assembly 12 located in the receiving space 51a from the protrusion 1111, reducing the probability of the battery assembly 12 directly contacting the support plate 50. At the same time, it is beneficial to make the area of ​​the first box wall 111 with the protrusion 1214 consistent with the other thicknesses, which is beneficial to reduce the overall size of the first box wall 111, thereby reducing the three-dimensional size of the receiving box 11, reducing the overall volume of the battery 10, and facilitating the improvement of the energy density and space utilization of the battery 10.

[0442] In some embodiments, see Figure 6 The height of the boss 1111 does not exceed 98.5% of the height of the raised portion 51. That is, H3 / H2 ≤ 98.5%.

[0443] This reduces the likelihood that the boss 1111 will abut against the inner wall of the accommodating space 51a along the height direction, thus affecting the arrangement between the battery 10 and the support plate 50.

[0444] In some embodiments, see Figure 6 The height of the boss 1111 accounts for 21% to 53% of the height of the raised portion 51. That is, 33% ≤ H3 / H2 ≤ 95.2%.

[0445] In this way, on the one hand, the probability of the boss 1111 abutting against the inner wall of the accommodating space 51a along the height direction is further reduced; on the other hand, it is beneficial to make the space in the accommodating part 11b for accommodating the battery assembly 12 larger.

[0446] In some embodiments, see Figure 12The battery assembly 12 also includes a battery cell 121, which includes a housing 1211. The housing 1211 has a first housing wall 1212, and the first housing wall 1212 includes a protrusion 1214. At least a portion of the protrusion 1214 is located in the receiving portion 11b, and the height dimension of the protrusion 1214 does not exceed 77% of the height dimension of the boss 1111. That is, H4 / H3 ≤ 77%.

[0447] In this way, on the one hand, it is beneficial to make the protrusion 1214 and the receiving part 11b spaced apart along the height direction of the battery 10, so as to reduce the probability of damage caused by direct contact between the two, and also facilitate the arrangement of other components of the battery assembly 12 in the receiving part 11b; on the other hand, it allows the thickness of the first box wall 111 to better protect the protrusion 1214.

[0448] In some embodiments, the height dimension of the protrusion 1214 accounts for 36% to 53% of the height dimension of the boss 1111. That is, 36% ≤ H4 / H3 ≤ 53%.

[0449] This further reduces the chance of damage caused by direct contact between the two components, and makes it more advantageous for arranging other parts of the battery assembly 12 in the housing 11b.

[0450] In some embodiments, see Figure 6 The battery assembly 12 includes a protrusion 12a, at least a portion of which is located in the receiving portion 11b. The height of the protrusion 12a does not exceed 94% of the height of the boss 1111. That is, H1 / H3 ≤ 94%.

[0451] This helps to reduce the probability of the protruding part 12a and the boss 1111 coming into contact in the vertical direction, and reduces the probability of damage caused by the contact.

[0452] In some embodiments, see Figure 6 The height dimension of the protruding portion 12a accounts for 74% to 86% of the height dimension of the boss 1111. That is, 74% ≤ H1 / H3 ≤ 86%.

[0453] This further reduces the probability of vertical contact between the protruding portion 12a and the boss 1111, and improves the space utilization rate of the protruding portion 12a to the receiving portion 11b.

[0454] In some embodiments, see Figure 42 and Figure 43The battery assembly 12 also includes a busbar 122, at least a portion of which is located in the receiving portion 11b. The distance between the inner wall of the receiving portion 11b and the busbar 122 along a first direction is not less than 1% of the dimension of the receiving portion 11b along the first direction, which is perpendicular to the thickness direction of the first housing wall 111. That is, L8 / L7 ≥ 1%.

[0455] This helps reduce the chance of a short circuit caused by contact between the busbar 122 and the inner wall of the housing 11b, allowing the battery assembly 12 to function normally.

[0456] In some embodiments, the ratio of the distance between the inner wall of the receiving portion 11b and the manifold 122 along the first direction to the dimension of the receiving portion along the first direction ranges from 2% to 10%. That is, 2% ≤ L8 / L7 ≤ 10%.

[0457] This further reduces the likelihood of a short circuit caused by contact between the busbar 122 and the inner wall of the receiving portion 11b.

[0458] In some embodiments, see Figure 5 and Figure 6 The battery assembly 12 includes a battery cell 121, and the battery cell 121 includes a terminal post 1213. The terminals post 1213 of at least two battery cells 121 are located in the same receiving portion 11b.

[0459] This facilitates the electrical connection of the terminals 1213 of different battery cells 121 within a single housing 11b, resulting in a more compact structure for the battery 10.

[0460] In some embodiments, see Figure 43 and Figure 45 The battery 10 includes a first insulating member 17, which is disposed on the inner wall of the receiving portion 11b.

[0461] In this way, by utilizing the insulating properties of the first insulating member 17, the risk of charge transfer between the battery assembly 12 and the inner wall of the housing 11b can be reduced, thereby reducing the risk of short circuits and other problems occurring during the use of the battery 10.

[0462] In some embodiments, see Figure 43 and Figure 45 The battery assembly 12 includes a battery cell 121, and the battery cell 121 includes a terminal post 1213. A first insulating member 17 is disposed opposite to the terminal post 1213.

[0463] The first insulating member 17 is positioned opposite to the terminal post 1213, meaning that the first insulating member 17 and the terminal post 1213 do not contain any other components from the battery assembly 12.

[0464] In this way, the probability of the terminal post 1213 coming into contact with the first box wall 111 due to relative movement between the battery assembly 12 and the first box wall 111 can be reduced, thereby reducing the risk of short circuit of the battery cell 121 due to contact between the terminal post 1213 and the first box wall 111.

[0465] It is understandable that the first insulating element 17 and the pole post 1213 can be spaced apart or attached together.

[0466] In some embodiments where a box wall body 1112 and a second sealing cover 1113 are provided, see [reference]. Figures 14 to 16 , Figure 43 The boss 1111 partially or entirely forms the second closed cover 1113.

[0467] This facilitates the disassembly and assembly of the boss 1111, enabling the inspection and maintenance of the battery assembly 12.

[0468] It is understandable that part of the boss 1111 is formed by the second closing cover 1113, and another part is formed by the box wall body 1112.

[0469] In some embodiments, see Figure 15 , Figure 16 and Figure 44 A portion of the casing body 1112 protrudes away from the receiving cavity 11a to form a mounting step 1112b. A second through hole 1112a passes through the mounting step 1112b, connecting to the receiving cavity 11a. A second sealing cover 1113 is detachably placed on the mounting step 1112b to seal the second through hole 1112a. The mounting step 1112b and the second sealing cover 1113 together form a boss 1111. This allows the boss 1111 to be disassembled, facilitating the inspection and maintenance of the battery assembly 12.

[0470] In some embodiments, the length direction of the boss 1111 is the same as the length direction of the receiving cavity 11a, and the two have the same dimensions along the length direction.

[0471] The length direction of the receiving cavity 11a is the same as the length direction of the battery 10.

[0472] This allows for maximizing the size of the housing 11b along the length of the battery 10, thereby enabling the size and volume of the housing 11b to adapt to various battery assemblies 12 of different sizes and shapes.

[0473] In some embodiments, the length direction of the boss 1111 is the same as the width direction of the receiving cavity 11a, and the length dimension of the boss 1111 is the same as the width dimension of the first box wall 111.

[0474] The width direction of the receiving cavity 11a is the width direction of the battery 10.

[0475] This allows for maximizing the size of the housing 11b along the width of the battery 10, thereby enabling the size and volume of the housing 11b to adapt to various battery assemblies 12 of different sizes and shapes.

[0476] In some embodiments, see Figure 13 The width of the boss 1111 does not exceed 500mm, i.e., l1≤500mm.

[0477] In this way, on the one hand, it is beneficial to have a larger flat area on the surface of the first box wall 111 so as to be compatible with other parts in the vehicle 100 and reduce the adverse effects of the boss 1111 on the arrangement of other parts in the vehicle 100; on the other hand, it reduces the adverse effects of the boss 1111's large width causing a reduction in its structural strength and reduces the probability of damage to the parts in the receiving part 11b due to deformation of the boss 1111.

[0478] In some embodiments, see Figure 13 The width of the boss 1111 ranges from 50mm to 300mm, i.e., 50mm≤l1≤300mm.

[0479] This ensures that the space within the housing 11b meets the arrangement requirements of the battery assembly 12.

[0480] The specific value of the width of the boss 1111 is not limited. For example, the width of the boss 1111 can be 50mm, 100mm, 200mm, 300mm, etc.

[0481] In some embodiments, see Figure 15 The height of the boss 1111 shall not exceed 300mm, i.e., l2≤300mm.

[0482] This facilitates the adaptation of other components in the vehicle 100 and reduces the adverse effects of the boss 1111 on the arrangement of other components in the vehicle 100. At the same time, it reduces the probability that the boss 1111 will be deformed and bent due to shear stress perpendicular to the height direction, thus damaging the battery assembly 12 in the housing 11b.

[0483] In some embodiments, see Figure 15 The height of the boss 1111 ranges from 5mm to 100mm, i.e., 5mm≤l2≤100mm.

[0484] This allows the space within the accommodating section 11b to meet the arrangement requirements of the protruding portion 12a.

[0485] The specific value of the height of the boss 1111 is not limited. For example, the width of the boss 1111 can be 5mm, 8mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, etc. See some embodiments. Figure 41 The width of the raised portion 51 shall not exceed 500mm, i.e., l3≤500mm.

[0486] This ensures that the space within the housing 11b meets the arrangement requirements of the battery assembly 12.

[0487] The specific value of the width dimension of the raised portion 51 is not limited. For example, the width dimension of the raised portion 51 can be 100mm, 200mm, 300mm, 400mm, 500mm, etc.

[0488] In some embodiments, see Figure 43 The height of the raised portion 51 shall not exceed 300mm, i.e., l4≤300mm.

[0489] In this way, it is compatible with other components in the vehicle 100, reducing the adverse effects of the boss 1111 on the arrangement of other components in the vehicle 100; at the same time, it reduces the probability that the raised portion 51 will be deformed and bent due to shear stress perpendicular to the height direction, thus damaging the battery assembly 12 in the receiving portion 11b.

[0490] The specific value of the height dimension of the raised portion 51 is not limited. For example, the height dimension of the raised portion 51 can be 50mm, 100mm, 150mm, 200mm, 250mm, 300mm, etc.

[0491] This disclosure also provides a battery 10 for use in a vehicle 100, see [reference]. Figures 2 to 12 The vehicle 100 includes a support plate 50, and a battery 10 is located on one side of the support plate 50. The support plate 50 has a raised portion 51 disposed away from the battery 10. A receiving space 51a is formed on the side of the raised portion 51 facing the battery 10. The battery 10 includes a receiving box 11 and a battery assembly 12. The battery assembly 12 is housed in the receiving box 11. The battery assembly 12 includes a protruding portion 12a for protruding toward the support plate 50 to extend into the receiving space 51a. In a projection plane perpendicular to the protrusion direction of the protruding portion 12a, the projection of a portion of the battery assembly 12 is located outside the projection of the protruding portion 12a.

[0492] In other words, part of the battery assembly 12 is located in the housing space 51a, and the other part is located outside the housing space 51a.

[0493] In this way, the battery 10 can make better use of the space formed by the raised portion 51, making the structure of the battery 10 more compact and improving the capacity of the battery 10 in the vehicle 100.

[0494] In some embodiments, see Figure 39 The housing 11 has a placement space 11d, in which the battery assembly 12 is placed. One side of the placement space 11d is open to form a first opening 11c, which is used to support the plate 50 to be placed on it.

[0495] In other words, when the battery 10 is not installed in the vehicle 100, the battery component 12 in the battery 10 is directly exposed to the outside world on the side facing the first opening 11c; when the battery 10 is installed in the vehicle 100, the battery component 12 is separated from the vehicle interior space 100a only by the support plate 50.

[0496] This simplifies the structure of the battery 10 and the vehicle 100, making the arrangement between the support plate 50 and the battery 10 more compact. Given a fixed volume of the internal space of the vehicle 100, this increases the capacity of the battery 10. At the same time, it facilitates the direct access to the battery assembly 12 for maintenance after the battery 10 is removed from the vehicle 100, through the first opening 11c.

[0497] In some embodiments, see Figure 38 and Figure 39 The battery 10 includes a temperature control component 14, which is located on the side of the battery assembly 12 facing the first opening 11c.

[0498] In this way, the temperature control component 14 absorbs the heat generated during the operation of the battery component 12, thereby reducing the operating temperature of the battery component 12 and improving the safety of the battery 10. At the same time, it reduces the heat transferred from the battery component 12 to the support plate 50 and radiated into the vehicle interior space 100a during the operation of the battery component 12.

[0499] In some embodiments, see Figure 38 and Figure 39 The battery 10 includes a first adhesive layer 13, which is used to bond the support plate 50 to the outer surface of the temperature control component 14.

[0500] In this way, the relative position between the temperature control component 14 and the support plate 50 is fixed by the first adhesive layer, reducing the probability of friction damage caused by relative movement between the two.

[0501] Understandably, the first adhesive layer 13 is located on the side of the temperature control component 14 facing the first opening 11c.

[0502] In some embodiments, see Figure 38 and Figure 39The battery 10 includes a third adhesive layer 16, which is adhered between the temperature control component 14 and the outer surface of the battery component 12.

[0503] This fixes the relative position between the temperature control component 14 and the battery component 12, reducing the chance of friction damage caused by relative movement between them.

[0504] In some embodiments, see Figures 13 to 16 , Figures 41 to 44 The container 11 includes a first container wall 111, which is located on one side of the container 11, and a portion of the first container wall 111 extends into the receiving space 51a.

[0505] Thus, during the separate transport of battery 10, the first box wall 111 can protect battery assembly 12 and reduce the probability of battery assembly 12 being damaged by impact.

[0506] In some embodiments, see Figures 13 to 16 , Figures 41 to 44 The container 11 includes a container body 112 and a lid. The first container wall 111 forms the lid. One side of the container body 112 is open to form a second opening 112a. The lid is placed on the second opening 112a to form a container cavity 11a with the container body 112. The battery 10 is placed in the container cavity 11a.

[0507] Thus, the housing 11 is formed by splicing the housing 112 and the housing cover, which makes it easy to disassemble the housing 11 according to actual needs, so that the battery assembly 12 can be installed in the housing phase and the battery assembly 12 can be inspected and maintained in the future.

[0508] In some embodiments, see Figures 42 to 44 The first box wall 111 includes a box wall body 1112 and a second sealing cover 1113. The box wall body 1112 is provided with a through second through hole 1112a, which communicates with the receiving cavity 11a. The second sealing cover 1113 is detachably connected to the box wall body 1112 to seal the second through hole 1112a.

[0509] Thus, the battery assembly 12 located in the receiving cavity 11a can be inspected and maintained simply by removing and installing the second sealing cover 1113 through the second through hole 1112a, without having to disassemble the box 112 and the cover, thereby improving the convenience and efficiency of inspection and maintenance.

[0510] In some embodiments, see Figures 42 to 44 The box cover also includes a second sealing element 1114, which is arranged around the periphery of the second through hole 1112a and sandwiched between the raised body 511 and the second sealing cover 1113 to seal the box wall body 1112 and the second sealing cover 1113.

[0511] In this way, the joint space between the box wall body 1112 and the second sealing cover 1113 and the second sealing member 1114 is reduced by the second sealing member 1114, thereby reducing the probability of foreign objects entering the receiving cavity 11a and affecting the operation of the battery assembly 12, extending the service life of the battery 10, and improving the safety of the battery 10.

[0512] The specific method by which the second sealing cover is detachably connected to the box wall body 1112 is not limited.

[0513] In some embodiments, the second sealing cover 1113 is mounted to the box wall body 1112 by threaded fasteners.

[0514] Thus, using threaded fasteners facilitates disassembly and improves the connection strength between the second sealing cover 1113 and the box wall body 1112.

[0515] It is understandable that one of the box wall body 1112 and the second sealing cover 1113 is provided with a through hole and the other is provided with a threaded hole, and the threaded fastener passes through and achieves threaded connection with the thread in the threaded hole.

[0516] In some embodiments, the second sealing cover 1113 is slidably snapped onto the box wall body 1112.

[0517] In other words, one of the second sealing cover 1113 and the box wall body 1112 is provided with a sliding groove, and a part of the other can be embedded in the sliding groove, so that the two can slide relative to each other.

[0518] Thus, by adopting a sliding mechanism, the second sealing cover 1113 can be opened or closed more quickly, improving the convenience of maintenance.

[0519] In some embodiments, the second sealing cover 1113 is hinged to the box wall body 1112.

[0520] In other words, the second sealing cover 1113 can rotate relative to the box wall body 1112 by means of hinge, so that the second sealing cover 1113 opens or closes the first through hole 511a.

[0521] Thus, by using a rotating mechanism, the second sealing cover 1113 can be opened or closed more quickly, improving the convenience of maintenance.

[0522] In some embodiments, see Figures 13 to 16 , Figures 41 to 44On the outer surfaces of opposite sides of a portion of the first housing wall 111, a boss 1111 is formed on one side surface and a receiving portion 11b is formed on the other side surface. At least a portion of the boss 1111 is used to extend into the receiving space 51a, and a portion of the battery assembly 12 is located in the receiving portion 11b.

[0523] Thus, by using the receiving portion 11b, a portion of the battery assembly 12 is located in the receiving space 51a, which protects the battery assembly 12 located in the receiving space 51a from the protrusion 1111, reducing the probability of the battery assembly 12 directly contacting the support plate 50.
