Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a battery pack and a vehicle having the battery pack. Background Technology

[0002] During use, battery packs expand to a certain extent due to gas generation caused by internal chemical reactions and volume changes in the battery pack materials, generating expansion forces between the batteries. In rigid battery pack structures, and due to inconsistencies within the battery pack itself, some batteries may experience excessive expansion forces, leading to rapid degradation and affecting the battery pack's lifespan.

[0003] In existing technologies, the focus is mainly on regulating the overall expansion force of the battery pack, which makes it difficult to regulate the expansion force of batteries in local locations. Furthermore, the regulation structure is relatively complex, affecting the energy density of the battery pack. Utility Model Content

[0004] This application aims to at least solve one of the technical problems existing in the prior art. To this end, in a first aspect, this application proposes a battery pack that can both regulate the overall expansion force and the expansion force of the batteries in local locations, and improve the energy density of the battery pack.

[0005] Secondly, this application proposes a vehicle that uses the aforementioned battery pack.

[0006] A battery pack according to a first aspect of the present application includes an adjustment plate, a battery, and a plurality of separators;

[0007] The plurality of the partitions are spaced apart from the adjustment plate along a first direction, and the adjacent partitions and the adjustment plate define an accommodating space in which the battery is placed;

[0008] The separator is configured to act on the regulating plate as the battery expands, causing the regulating plate to undergo tensile deformation along the first direction.

[0009] The battery pack according to the embodiments of this application has at least the following beneficial effects:

[0010] The battery pack in this application, by setting a separator connecting the adjustment plate, allows the expansion force of the battery to be transmitted to the adjustment plate through the separator when the battery expands, causing the adjustment plate to stretch and deform, thus achieving adaptive adjustment. Moreover, this adjustment is applicable to the battery in each accommodating space. Therefore, it can not only adjust the overall expansion force, but also adjust the expansion force of the battery in any accommodating space, achieving a balanced expansion force of the batteries in each accommodating space. This effectively solves the shortcomings of traditional structures, and the structural design is simple, which helps to improve the energy density of the battery pack.

[0011] According to some embodiments of this application, the adjusting plate includes a first end face and a second end face opposite to each other. The adjusting plate has a first groove on the first end face and a second groove on the second end face. The length directions of both the first and second grooves intersect in the first direction, and the first and second grooves are staggered along the first direction. Thus, the adjusting plate, through the first and second grooves, can form a spring-like structure, enabling stretching and compression deformation over a certain distance, thereby adjusting the overall expansion force of the battery pack through telescoping.

[0012] According to some embodiments of this application, the first end face faces the battery, and at least a portion of the separator is inserted into the corresponding first groove. This facilitates the separator's transfer of the battery's expansion force to the adjustment plate and simplifies the separator's installation design.

[0013] According to some embodiments of this application, along the first direction, the width of the first groove is smaller than the width of the battery. This prevents the battery from getting stuck in the first groove, thus helping to ensure the stability and consistency of the battery's installation within the accommodating space.

[0014] According to some embodiments of this application, the length direction of the first groove is perpendicular to the first direction;

[0015] And / or, the depth direction of the first groove is perpendicular to the first direction.

[0016] This makes it easier to process the first groove, and also makes it easier to insert the partition into the first groove.

[0017] According to some embodiments of this application, the accommodating space, in its vertical projection onto the adjusting plate, covers at least one of the second grooves. Therefore, in the event of battery expansion within the accommodating space, the section of the adjusting plate corresponding to the accommodating space has sufficient deformation space along the first direction, enabling adjustment of the expansion force of the battery within a single accommodating space.

[0018] According to some embodiments of this application, the thickness of the separator along the first direction is 1 mm to 3 mm. This balances the strength of the separator with the energy density of the battery pack.

[0019] According to some embodiments of this application, along the first direction, the adjusting plate includes alternately connected straight segments and arc-shaped segments. Thus, adaptive tensile deformation can be achieved by utilizing the extended deformation of the arc-shaped segments.

[0020] According to some embodiments of this application, the battery pack includes a plurality of adjusting plates along a second direction perpendicular to the first direction, and at least one adjusting plate is connected to the separator along the second direction. Thus, the battery expansion force can be adjusted jointly by multiple adjusting plates, reducing the strength requirements of a single adjusting plate and extending its service life.

[0021] The vehicle according to the second aspect of this application includes the battery pack described in any of the above embodiments.

[0022] The vehicle according to the embodiments of this application has at least the following beneficial effects:

[0023] The vehicle described in this application, by applying the aforementioned battery pack, can both adjust the overall expansion force and adjust the expansion force of the battery in any accommodating space, achieving a balanced expansion force of the battery in each accommodating space. This effectively solves the shortcomings of traditional battery pack structures, while also having a simple structural design and high reliability.

[0024] Additional aspects and advantages of this application will be set forth in part in the description which follows, and some of these additional aspects and advantages will become apparent from the description or may be learned by practice of this application. Attached Figure Description

[0038] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0039] In the description of this application, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0040] Reference Figures 1 to 3 This application provides a battery pack comprising an adjusting plate 100, a battery 300, and a plurality of separators 200. The plurality of separators 200 are spaced apart from the adjusting plate 100 along a first direction, and an accommodating space is defined between two adjacent separators 200 and the adjusting plate 100, within which the battery 300 is placed. The separators 200 are configured to act on the adjusting plate 100 as the battery 300 expands, causing the adjusting plate 100 to undergo tensile deformation along the first direction.

[0041] In this embodiment, the partition 200 and the adjusting plate 100 can be fixedly connected, such as by welding, integral molding, riveting, etc., or they can be detachably connected, such as by screw connection, plug-in connection, snap-fit ​​connection, etc.

[0042] It is understandable that the number of batteries 300 is determined according to the actual design requirements of the battery pack, and is not specifically limited here. When the battery pack has multiple batteries 300, two separators 200 can be provided, defining an accommodating space between the two separators 200 and the adjusting plate 100, and multiple batteries 300 are stacked in the accommodating space along the first direction. Alternatively, three or more separators 200 can be provided to define two or more accommodating spaces between themselves and the adjusting plate 100, with multiple batteries 300 correspondingly stacked in different accommodating spaces.

[0043] Since the battery 300 is located within the accommodating space, when the battery 300 expands, it applies an expansion force to the separator 200 that defines the accommodating space. The separator 200 is connected to the adjusting plate 100, so the separator 200 transmits the expansion force to the adjusting plate 100, causing the adjusting plate 100 to stretch and deform, achieving adaptive adjustment. Furthermore, the expansion of any battery 300 within any accommodating space can be adjusted through the above mechanism. Therefore, the battery pack of this embodiment can adjust the overall expansion force as well as the expansion force of any battery 300 within any accommodating space, achieving a balanced expansion force across all accommodating spaces and effectively solving the shortcomings of traditional battery pack structures. At the same time, the structural design is simple and highly reliable. Compared to traditional complex structures, the separator 200 and adjusting plate 100 have a simple structure, occupy less space, and are beneficial for improving the energy density of the battery pack.

[0044] It should be noted that since the battery 300 mainly expands at the end with the largest surface area, that is, the battery 300 expands in the thickness direction, when placing the battery 300 in the accommodating space, its thickness direction should be the same as the first direction, so that the end with the largest surface area is opposite to the separator 200.

[0045] Reference Figure 2 and Figure 3 In some embodiments of this application, the adjusting plate 100 includes a first end face and a second end face opposite to each other. The adjusting plate 100 has a first groove 101 on the first end face and a second groove 102 on the second end face. The length directions of the first groove 101 and the second groove 102 intersect in a first direction. Furthermore, the first groove 101 and the second groove 102 are staggered along the first direction.

[0046] In this embodiment, the length directions of the first groove 101 and the second groove 102 both intersect with the first direction, meaning that the length directions of the first groove 101 and the second groove 102 are not parallel to the first direction. Since the first groove 101 and the second groove 102 are located on opposite end faces of the adjusting plate 100 and are offset along the first direction, the adjusting plate 100 forms a spring-like structure. Under external force, the first groove 101 and the second groove 102 can achieve tensile and compressive deformation over a certain distance, and the overall expansion force of the battery pack can be adjusted by telescopic adjustment.

[0047] Meanwhile, the material of the regulating plate 100 can be designed to have a certain deformation recovery ability after tensile and compressive deformation, so that the regulating plate 100 has elastic deformation. When the battery 300 expands, the regulating plate 100 can apply appropriate pressure to the battery 300 while adaptively elongating, so as to better achieve the overall expansion force balance of the battery pack.

[0048] Reference Figure 1 and Figure 2 In some embodiments of this application, the first end face faces the battery 300, and at least a portion of the separator 200 is inserted into the corresponding first groove 101. It is understood that this embodiment utilizes the first groove 101 to install the separator 200, which facilitates the separator 200 in transmitting the expansion force of the battery 300 to the adjusting plate 100, enabling the adjusting plate 100 to adapt to stretching deformation in a timely manner. It also simplifies the installation design of the separator 200, eliminating the need for additional structures to install it.

[0049] In some embodiments of this application, the adjusting plate 100 is located at the bottom of the battery 300, with its first end face being the upper end face and its second end face being the lower end face. Both the battery 300 and the separator 200 are supported on the adjusting plate 100. With this structural arrangement, the separator 200 can ensure stability within the first groove 101 under gravity, preventing it from easily detaching. When the battery 300 expands, the force applied to the separator 200 is horizontal, preventing it from detaching from the first groove 101. Simultaneously, the two accommodating spaces of the battery 300 clamp the separator 200, preventing it from detaching upwards from the first groove 101, thus facilitating the transfer of force from the separator 200 to the adjusting plate 100.

[0050] Therefore, the structural design of this embodiment is beneficial to improving the installation stability of the partition 200 and the timely adaptive adjustment of the adjustment plate 100.

[0051] Reference Figure 1 and Figure 2In some embodiments of this application, two partitions 200 are disposed on both sides of the adjusting plate 100 along the first direction, and the remaining partitions 200 are spaced apart and inserted into the first groove 101 along the first direction. Each pair of adjacent partitions 200 defines an accommodating space with the adjusting plate 100.

[0052] The structural arrangement of this embodiment, which utilizes the two outermost partitions 200 to form end plates, helps to simplify the structural design of the battery pack. The two outermost partitions 200 can be fixedly connected to the adjusting plate 100, or they can be fixedly connected to the battery pack's housing frame.

[0053] In some embodiments of this application, the width of the first groove 101 along the first direction is smaller than the width of the battery 300.

[0054] Understandably, since the first end face faces the battery 300, and the battery 300 can abut against the first end face, if the width of the first groove 101 is greater than or equal to the width of the battery 300, the battery 300 can be inserted into the first groove 101. When the battery 300 is inserted into the first groove 101, the contact area between adjacent batteries 300 will be reduced, which is not conducive to adjusting the overall balance of the battery pack. Furthermore, the side of the battery 300 facing away from the first end face will become uneven, affecting the energy density of the battery pack and the consistency of battery 300 installation.

[0055] In this embodiment, by controlling the width of the first groove 101 to be smaller than the width of the battery 300, the battery 300 can be effectively prevented from getting stuck in the first groove 101. This helps to ensure the installation stability and consistency of the battery 300 within the accommodating space, and makes it easier for the adjusting plate 100 to adjust the overall expansion force balance of the battery pack.

[0056] Especially when the adjustment plate 100 is located at the bottom of the battery 300, by controlling the width of the first groove 101 to be smaller than the width of the battery 300, the battery 300 can be effectively prevented from falling into the first groove 101.

[0057] Reference Figures 1 to 3 In some embodiments of this application, the length direction of the first groove 101 is perpendicular to the first direction. It is understood that the batteries 300 are stacked along the first direction, and the outer contour of the batteries 300 is typically rectangular. By setting the length of the first groove 101 perpendicular to the first direction, and with the partition 200 inserted into the first groove 101, the partition 200 is also perpendicular to the first direction, thereby making the batteries 300 perpendicular to the first direction as well. This helps to control the adjusting plate 100 to its shortest length, which is beneficial for controlling production costs. Furthermore, setting the first groove 101 perpendicular to the first direction, compared to other angled configurations, facilitates its processing and shaping.

[0058] Based on the structure of the above embodiments, in some embodiments of this application, the depth direction of the first groove 101 is also perpendicular to the first direction. This structural arrangement facilitates the direct insertion of the partition 200 into the first groove 101, and also facilitates the processing and shaping of the first groove 101.

[0059] In some embodiments of this application, the length and depth directions of the second groove 102 are both perpendicular to the first direction. Similarly, this embodiment facilitates the processing and forming of the second groove 102 by setting the length and depth directions of the second groove 102 perpendicular to the first direction.

[0060] Reference Figure 1 and Figure 2 In some embodiments of this application, the accommodating space covers at least one second groove 102 in the vertical projection of the adjustment plate 100.

[0061] It is understood that when the battery 300 expands, the adjusting plate 100 enhances the extension deformation (i.e., tensile deformation) along the first direction based on the first groove 101 and the second groove 102, thereby achieving adaptive adjustment. In this embodiment, the adjusting plate 100 has at least one second groove 102 in each section opposite to each accommodating space, which can ensure that the section has a certain amount of tensile deformation. When the battery 300 in the accommodating space expands, the adjusting plate 100 can achieve the adjustment of the expansion force of the battery 300 in the accommodating space by stretching the section along the first direction.

[0062] In some embodiments of this application, the section of the adjusting plate 100 corresponding to the accommodating space has a first groove 101 and two second grooves 102, with the two second grooves 102 located on both sides of the first groove 101 along a first direction. Using the structural configuration of this embodiment, the area of ​​the adjusting plate 100 corresponding to the accommodating space, through the two second grooves 102 and the first groove 101, can effectively ensure the amount of tensile deformation along the first direction, which is beneficial for the section to undergo timely adaptive tensile deformation.

[0063] Reference Figures 1 to 3In some embodiments of this application, the sum of the depths of the first groove 101 and the second groove 102 is greater than the thickness of the adjusting plate 100. Preferably, the depth of both the first groove 101 and the second groove 102 exceeds half the thickness of the adjusting plate 100. Taking the adjusting plate 100 located at the bottom of the battery 300 as an example, the first groove 101 extends downward from the upper end of the adjusting plate 100, and the second groove 102 extends upward from the lower end of the adjusting plate 100. The horizontal height of the lower end of the first groove 101 is lower than the horizontal height of the upper end of the second groove 102. With the structural configuration of this embodiment, the adjusting plate 100 can form an S-shaped bending structure along the first direction through the first groove 101 and the second groove 102, which helps to further improve the tensile deformation capacity and the amount of tensile deformation.

[0064] In some embodiments of this application, the thickness of the separator 200 along the first direction is 1 mm to 3 mm. Since the separator 200 needs to transfer the expansion force from the battery 300 to the adjusting plate 100, allowing the adjusting plate 100 to adaptively stretch and deform, this embodiment ensures the structural strength of the separator 200 by controlling its thickness to 1 mm to 3 mm. Simultaneously, since the separator 200 and the battery 300 are arranged along the first direction, controlling the thickness of the separator 200 to 1 mm to 3 mm avoids the separator 200 occupying too much space along the first direction, thus helping to ensure the energy density of the battery pack.

[0065] In actual setups, the thickness of the partition 200 can be set to 1mm, 1.5mm, 2mm, 3mm, etc.

[0066] In some embodiments of this application, the separator 200 is a rigid structure so as to effectively transfer the expansion force of the battery 300 to the regulating plate 100.

[0067] In addition, depending on the design requirements of the battery pack, an air duct structure can be set within the separator 200 to achieve an air-cooled battery 300 cooling design; or a liquid-cooling structure can be set within the separator 200 to achieve a liquid-cooled battery 300 cooling design. The separator 200 can also be set as an elastic structure, as long as it can meet the adjustment mechanism for transmitting the expansion force of the battery 300.

[0068] In some embodiments of this application, the battery pack includes a plurality of adjustment plates 100 along a second direction perpendicular to the first direction, and a partition 200 connects at least one adjustment plate 100 along the second direction.

[0069] Understandably, in some cases, a battery pack has multiple batteries 300 stacked along a first direction, and each battery 300 has a certain length along a direction perpendicular to the first direction. If the expansion force of all batteries 300 is adjusted using a single adjusting plate 100, the structural strength requirements for the adjusting plate 100 would be significant. This embodiment uses multiple adjusting plates 100 arranged along a second direction (i.e., the length direction of the battery 300) to collectively adjust the overall expansion force of the battery pack. This reduces the strength requirements of a single adjusting plate 100, which is beneficial for controlling production costs. It also helps extend the service life of the adjusting plates 100.

[0070] Reference Figure 4 In some embodiments of this application, along the second direction, the battery pack includes two adjusting plates 100. The upper surfaces of the two adjusting plates 100 are aligned with a first groove 101, and the lower surfaces are aligned with a second groove 102. Multiple partitions 200 are spaced apart along the first direction, and each partition 200 is simultaneously inserted into the first groove 101 of the two adjusting plates 100. The battery 300 is placed within the accommodating space defined between two adjacent partitions 200 and supported on the two adjusting plates 100.

[0071] With the structural arrangement of this embodiment, when the battery 300 expands within the accommodating space, the separator 200 will be subjected to the expansion force of the battery 300, and this force will be transmitted to the two adjusting plates 100. The two adjusting plates 100 will then stretch and deform together under the action of the battery 300 expansion force, achieving adaptive adjustment. In this embodiment, the separator 200 transmits the force to the two adjusting plates 100, and the two adjusting plates 100 are used for adaptive adjustment. In actual settings, more adjusting plates 100 can be set, and the number of adjusting plates 100 connected to the separator 200 can be changed to transmit the force to the correspondingly connected adjusting plates 100.

[0072] Reference Figure 5 In some embodiments of this application, the adjusting plate 100 includes alternating straight segments 104 and arc-shaped segments 103 along a first direction. When the adjusting plate 100 is subjected to a force transmitted by the partition 200, it can stretch the arc-shaped segments 103 to both sides, achieving an adaptive adjustment effect of stretching deformation.

[0073] It is understandable that the adjusting plate 100 can also be configured as a wave-shaped structure or other structures along the first direction, as long as it can be stretched and deformed along the first direction.

[0074] Reference Figures 1 to 3In some embodiments of this application, the battery pack includes an adjustment plate 100, a battery 300, and five separators 200. The upper surface of the adjustment plate 100 has three first grooves 101 spaced parallel to and at intervals along a first direction. The lower surface of the adjustment plate 100 has four second grooves 102 spaced parallel to and at intervals along the first direction. The first grooves 101 and second grooves 102 are alternately arranged along the first direction, such that there is one first groove 101 between every two second grooves 102. The length and depth directions of the first grooves 101 and second grooves 102 are both perpendicular to the first direction. Furthermore, the depth of both the first grooves 101 and second grooves 102 exceeds half the thickness of the adjustment plate 100, causing the first grooves 101 and second grooves 102 to partially overlap in the vertical projection direction. This results in the adjustment plate 100 having an S-shaped bending structure. Of the five partitions 200, two partitions 200 are located at both ends of the adjusting plate 100 along the first direction, and three partitions 200 are correspondingly inserted into the three first grooves 101. The upper heights of the five partitions 200 are kept the same. The five partitions 200 and the adjusting plate 100 together define four accommodating spaces, which are obviously located at the upper end of the adjusting plate 100. Eight batteries 300 are provided, and two batteries 300 are stacked in each of the four accommodating spaces along the first direction, that is, two batteries 300 are stacked in each accommodating space along the first direction. In the initial state, along the first direction, the thickness of the two batteries 300 is the same as the width of the accommodating space, so that the batteries 300 fit against the partitions 200. Along the first direction, the width of the first groove 101 is the same as the thickness of the partition 200, and the width of the first groove 101 is the same as the width of the second groove 102. Along the first direction, the first groove 101 and the second groove 102 are equidistantly distributed, such that each second groove 102 is opposite to the midpoint of the accommodating space directly above.

[0075] With the structural arrangement of this embodiment, when the battery 300 in any of the accommodating spaces expands, the expansion force is applied to the attached separator 200 and transmitted to the adjusting plate 100 through the separator 200. Since the section of the adjusting plate 100 corresponding to each accommodating space is "∏"-shaped, when subjected to expansion force, this section can open to both sides along the first direction, achieving adaptive stretching and thus adjusting the expansion force of the battery 300. Furthermore, since the four accommodating spaces are adjacent to each other on the upper end of the adjusting plate 100, the overall expansion force of the battery 300 can be adjusted to a balanced state through the adjusting plate 100.

[0076] Embodiments of this application also propose a vehicle that includes the battery pack of any of the above embodiments.

[0077] It is understood that the vehicle in this application, by applying the above-mentioned battery pack, can not only adjust the overall expansion force, but also adjust the expansion force of the battery 300 in any accommodating space, so as to achieve the effect of balanced expansion force of the battery 300 in each accommodating space, effectively solving the shortcomings of the traditional battery pack structure, while the structure design is simple and highly reliable.

[0078] It should be noted that the vehicles mentioned in this application can be private cars, such as sedans, SUVs, MPVs, or pickup trucks. Vehicles can also be commercial vehicles, such as vans, buses, small trucks, or large semi-trailers. Vehicles can be gasoline-powered or new energy vehicles. When a vehicle is a new energy vehicle, it can be a hybrid or a pure electric vehicle.

[0079] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
