[0128] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0131] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0132] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," and "attached" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0133] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0134] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0135] The term "plurality" used in this application refers to two or more (including two).

[0136] In this application, a battery 100 refers to a single physical module that includes at least one battery module 20 to provide higher voltage and capacity. Multiple battery modules 20 can be connected in series, in parallel, or in a mixed connection to form the battery 100. Mixed connection means that multiple battery modules 20 are connected in series and in parallel. The battery module 20 can include one or more battery cells 221. When the battery module 20 includes multiple battery cells 221, the multiple battery cells 221 of the battery module 20 can be connected in series, in parallel, or in a mixed connection. The battery module 20 can also include a housing 21 for encapsulating one or more battery cells 221. The housing 21 can prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells 221. The housing 21 can have a variety of structures. For example, in some embodiments, the housing 21 can include a first part and a second part. The first part and the second part cover each other to form a receiving cavity 201, and the battery cells 221 are placed in the receiving cavity 201.

[0137] In the present application, the battery cells 221 may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and the embodiments of the present application do not limit this. The battery cells 221 may be cylindrical, flat, rectangular, or other shapes, and the embodiments of the present application do not limit this. The battery cells 221 are generally divided into three types according to the packaging method: cylindrical battery cells, square battery cells, and soft-pack battery cells, and the embodiments of the present application do not limit this.

[0138] For example, a battery cell 221 may include a battery shell, an electrode assembly, and an electrolyte, and the battery shell is used to accommodate the electrode assembly and the electrolyte. The electrode assembly is composed of a positive electrode sheet, a negative electrode sheet, and a separator. The battery cell 221 mainly relies on the movement of metal ions between the positive electrode sheet and the negative electrode sheet to work. The positive electrode sheet includes a positive electrode collector and a positive electrode active material layer. The positive electrode active material layer is coated on the surface of the positive electrode collector. The positive electrode collector not coated with the positive electrode active material layer protrudes from the positive electrode collector coated with the positive electrode active material layer, and the positive electrode collector not coated with the positive electrode active material layer serves as the positive electrode tab. Taking lithium-ion batteries as an example, the material of the positive electrode collector can be aluminum, and the positive electrode active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc.

[0139] The negative electrode sheet consists of a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative current collector. The negative current collector uncoated with the negative active material layer protrudes from the negative current collector coated with the negative active material layer. The negative current collector uncoated with the negative active material layer serves as the negative electrode tab. The negative current collector can be made of copper, and the negative active material can be carbon, silicon, or other materials. To ensure that high currents can pass without melting, multiple positive electrode tabs are stacked together, and multiple negative electrode tabs are stacked together.

[0140] The material of the isolation film may be PP (polypropylene) or PE (polyethylene), etc. In addition, the electrode assembly may be a wound structure or a laminated structure, but the embodiments of the present application are not limited thereto.

[0141] With the development of battery technology, more and more vehicles are using batteries as a power source. When batteries are used as a power source in vehicles, they are typically mounted to the vehicle's beam. When the battery needs maintenance or replacement, it typically needs to be removed from the beam. When removed from the beam, the battery is susceptible to significant impact forces due to its own gravity. Excessive or prolonged impact forces can easily damage the battery's internal structure, seriously shortening its service life.

[0142] Based on this, in order to reduce or avoid damage to the battery 100 due to impact force, the applicant has conducted in-depth research and proposed a battery 100, which is used to be installed on the vehicle beam 70 of the vehicle 1000. The battery 100 includes a load-bearing bracket 10 and at least one battery module 20. The load-bearing bracket 10 is used to bear the weight of the battery module 20 and is suitable for being detachably connected to the vehicle beam 70.

[0143] In the technical solution of the present application, a load-bearing bracket 10 is provided for bearing the weight of the battery module 20 and the load-bearing bracket 10 is detachably connected to the vehicle beam 70, so as to facilitate the replacement and maintenance of the battery 100. In the process of removing the battery 100 from the vehicle beam 70, the load-bearing bracket 10 can buffer and protect the battery 100, thereby reducing the damage to the battery 100 due to the large impact force under the action of its own gravity, and extending the service life of the battery 100. In addition, during the operation of the vehicle 1000, the impact force exerted on the battery module 20 can be transmitted to the load-bearing bracket 10, thereby dispersing the impact force exerted on the battery module 20, thereby reducing or avoiding damage to the battery module 20 due to the impact force, and extending the service life of the battery 100.

[0144] The battery 100 disclosed in the embodiment of the present application can be used in a vehicle 1000 , and a power supply system of the vehicle 1000 including the battery 100 disclosed in the present application can be configured to reduce or avoid damage to the battery 100 due to impact force.

[0145] An embodiment of the present application provides a vehicle 1000 using the battery 100 as a power source. The vehicle 1000 may be, but is not limited to, a truck, an engineering vehicle, a car, and the like.

[0146] The following describes a battery 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0147] As shown in Figures 1 to 3, an embodiment of the present application provides a battery 100, which is used to be installed on the beam 70 of a vehicle 1000. The battery 100 includes a load-bearing bracket 10 and at least one battery module 20. The load-bearing bracket 10 is used to bear the weight of the battery module 20 and is suitable for being detachably connected to the beam 70.

[0148] The main function of the load-bearing bracket 10 is to bear the weight of all battery modules 20 and also to install and secure the battery modules 20. The load-bearing bracket 10 can be a metal bracket, for example, a steel structure bracket, which can make the load-bearing bracket 10 have a high structural strength, thereby stably and reliably supporting multiple battery modules 20.

[0149] Optionally, at least one battery module 20 is detachably mounted on the load-bearing bracket 10. It may be that one of the battery modules 20 is detachably mounted on the load-bearing bracket 10, or some of the battery modules 20 are detachably mounted on the load-bearing bracket 10, or each battery module 20 is detachably mounted on the load-bearing bracket 10.

[0150] The phrase "the battery module 20 is detachably mounted on the load-bearing bracket 10" means that the battery module 20 can be removed from the load-bearing bracket 10 and reinstalled on the load-bearing bracket 10. The detachable connection method of the battery module 20 may include at least one of a snap connection method and a fastener connection method.

[0151] The accommodating space 101 defined within the load-bearing bracket 10 for accommodating the battery module 20 is in communication with the external environment. The accommodating space 101 defined within the load-bearing bracket 10 for accommodating the battery module 20 is an open space, which allows at least a portion of the battery module 20 to be exposed to the external environment, facilitating the assembly and disassembly and maintenance of the battery module 20. For example, the load-bearing bracket 10 may be a bracket structure having a hollow structure, or the load-bearing bracket 10 may be a bracket structure with one side open, such as the upper side of the load-bearing bracket 10 may be open, so that the battery module 20 can be easily loaded into or removed from the load-bearing bracket 10 from above.

[0152] The load-bearing bracket 10 is adapted to be detachably connected to the vehicle beam 70, and the battery 100 is connected to the vehicle beam 70 via the load-bearing bracket 10, thereby enabling the battery 100 to be detachably connected to the vehicle beam 70. The detachable connection of the battery 100 to the vehicle beam 70 means that the battery 100 can be removed from the vehicle beam 70 and reinstalled to the vehicle beam 70 after removal. The detachable connection method of the battery 100 can include at least one of a snap connection method and a fastener connection method. For example, the load-bearing bracket 10 can be detachably connected to the vehicle beam 70 using at least one of a snap connection method and a fastener connection method.

[0153] In the above technical solution, a load-bearing bracket 10 is provided for bearing the weight of the battery module 20 and the load-bearing bracket 10 is detachably connected to the vehicle beam 70, so that the replacement and maintenance of the battery 100 are facilitated. In the process of removing the battery 100 from the vehicle beam 70, the load-bearing bracket 10 can buffer and protect the battery 100, thereby reducing the damage to the battery 100 due to the large impact force under the action of its own gravity, and extending the service life of the battery 100. In addition, during the operation of the vehicle 1000, the impact force exerted on the battery module 20 can be transmitted to the load-bearing bracket 10, thereby dispersing the impact force exerted on the battery module 20, thereby reducing or avoiding damage to the battery module 20 due to the impact force, and extending the service life of the battery 100.

[0154] In some embodiments, referring to FIG. 4 to FIG. 7 , the battery module 20 includes a housing 21 and at least one battery cell 221 . The battery cell 221 is disposed in the housing 21 . The housing 21 is detachably connected to the load-bearing bracket 10 .

[0155] The housing 21 of the battery module 20 defines a sealed accommodating cavity 201 , and the battery cell 221 is disposed in the sealed accommodating cavity 201 defined by the housing 21 , which can protect the battery cell 221 .

[0156] The housing 21 may be a metal part or a non-metal part. When the housing 21 is a metal part, an insulating structure may be provided between the battery cell 221 and the housing 21 to insulate and separate the battery cell 221 from the housing 21 .

[0157] The battery module 20 includes at least one battery cell 221, which means that a single battery module 20 can include one battery cell 221, or a single battery module 20 can include multiple battery cells 221. When the battery module 20 includes multiple battery cells 221, the multiple battery cells 221 can be divided into at least one battery group 22, and the battery group 22 includes multiple battery cells 221 arranged side by side. When the battery module 20 includes multiple battery groups 22, the multiple battery groups 22 can be arranged horizontally, vertically, or both horizontally and vertically.

[0158] In the above technical solution, the battery module 20 can be sealed by its own outer shell 21, and the outer shell 21 of the battery module 20 is detachably connected to the load-bearing bracket 10, so that the detachable connection between the battery module 20 and the load-bearing bracket 10 can be conveniently realized. Moreover, the detachable connection between the outer shell 21 of the battery module 20 and the load-bearing bracket 10 can make the battery module 20 more reliably installed and fixed to the load-bearing bracket 10 compared to fixing the battery module 20 by pressing, and at the same time, it can also avoid the problem of extrusion damage to the battery module 20 caused by the pressing and fixing method.

[0159] In some embodiments, referring to Figures 5-7, the housing 21 includes a base plate 212 and a shell 211, the shell 211 is connected to the upper side of the base plate 212, and a accommodating cavity 201 for accommodating a battery cell 221 is defined between the shell 211 and the base plate 212, and the base plate 212 is supported on the load-bearing bracket 10 and the base plate 212 is detachably connected to the load-bearing bracket 10.

[0160] The lower side of the shell 211 is open, and the bottom plate 212 is used to cover the lower side of the shell 211 , so that a sealed accommodating cavity 201 can be defined between the shell 211 and the bottom plate 212 .

[0161] In the above technical solution, the battery module 20 is supported and connected to the load-bearing bracket 10 through its own base plate 212, so that the battery module 20 can be stably supported by the load-bearing bracket 10 and the battery module 20 can be more reliably fixed on the load-bearing bracket 10.

[0162] Optionally, the thickness of the base plate 212 can be greater than the thickness of the shell 211, so that the base plate 212 has a higher structural strength, can provide stable support for the battery cell 221, and can make the overall center of gravity of the battery module 20 lower, so that the battery module 20 is more stable as a whole after being installed on the load-bearing bracket 10.

[0163] In some embodiments, the projection of the housing 211 on the horizontal plane is a first projection, the projection of the bottom plate 212 on the horizontal plane is a second projection, and the first projection is located within the second projection. The phrase "the first projection is located within the second projection" means that the outer contour of the first projection is located on the inner circumference of the outer contour of the second projection.

[0164] In the above technical solution, since the projection of the shell 211 on the horizontal plane is located within the projection of the base plate 212 on the horizontal plane, the base plate 212 can be set larger, which can increase the supporting area of ​​the load-bearing bracket 10 for the battery module 20, thereby further improving the stability of the load-bearing bracket 10 in supporting the battery module 20.

[0165] In some embodiments, fasteners are passed through the bottom plate 212 and the load-bearing bracket 10 to mount the battery module 20 on the load-bearing bracket 10 .

[0166] The fastener may be a threaded fastener, the fastener may be threadedly connected to the base plate 212 and the fastener may be threadedly connected to the load-bearing bracket 10 .

[0167] In the above technical solution, the fasteners are passed through the base plate 212 and the load-bearing bracket 10, which can realize the detachable connection between the battery module 20 and the load-bearing bracket 10. The battery module 20 can be locked on the load-bearing bracket 10 through the connection method of the fasteners; and the connection method of the fasteners can not only realize the detachable connection between the battery module 20 and the load-bearing bracket 10, making the disassembly and assembly of the battery module 20 convenient, but also ensure the installation stability and reliability of the battery module 20.

[0168] In some embodiments, referring to FIG. 5 and FIG. 6 , a connecting flange 2111 is formed on the lower edge of the housing 211 , and the connecting flange 2111 is detachably connected to the bottom plate 212 .

[0169] The connecting flange 2111 formed on the lower edge of the housing 211 can be formed by folding the lower edge of the lower housing 211 outward. The connecting flange 2111 can overlap with the bottom plate 212 in the vertical direction and be located on the upper surface of the bottom plate 212, thereby facilitating the connection between the connecting flange 2111 of the housing 211 and the bottom plate 212. A sealing member can be provided at the connection between the connecting flange 2111 of the housing 211 and the bottom plate 212 to achieve a sealed connection between the housing 211 and the bottom plate 212.

[0170] The "detachable connection between the connecting flange 2111 and the bottom plate 212" means that the housing 211 can be separated from the bottom plate 212 to open the accommodating cavity 201, and the removed housing 211 can be reinstalled on the bottom plate 212. The detachable connection between the connecting flange 2111 and the bottom plate 212 can include at least one of a snap connection and a fastener connection.

[0171] In the above technical solution, a connecting flange 2111 is provided on the lower edge of the shell 211 to facilitate the connection and fixation between the shell 211 and the base plate 212, and the connecting flange 2111 and the base plate 212 are detachably connected, so that the battery module 20 can be opened to facilitate the maintenance of the battery cells 221 in the battery module 20.

[0172] In some embodiments, referring to FIG. 1 to FIG. 3 , a plurality of locking accessories 164 are provided on the load-bearing bracket 10 at intervals. The locking accessories 164 are adapted to be detachably connected to the vehicle beam 70 to lock the battery 100 to the vehicle beam 70 .

[0173] When the battery 100 is installed on the vehicle beam 70, the multiple locking accessories 164 on the load-bearing bracket 10 are connected to the vehicle beam 70, so that the battery 100 can be reliably installed and fixed to the vehicle beam 70, and the docking connector 52 on the battery 100 is electrically connected to the corresponding structure on the vehicle body 200; when the battery 100 is removed from the vehicle beam 70, the multiple locking accessories 164 on the load-bearing bracket 10 are disconnected from the vehicle beam 70, and the docking connector 52 on the battery 100 is separated from the corresponding structure on the vehicle body 200.

[0174] In the above technical solution, by arranging a plurality of locking accessories 164 on the load-bearing bracket 10, the battery 100 can be conveniently and reliably installed and fixed to the beam 70 of the vehicle body 200, and the battery 100 can be conveniently removed from or installed on the beam 70, thereby facilitating the maintenance and replacement of the battery 100.

[0175] In some embodiments, referring to FIG. 1-FIG . 3 , at least some of the locking members 164 are adapted to be spaced apart along the length of the beam 70 .

[0176] At least some of the locking components 164 are suitable for being arranged at intervals along the length direction of the vehicle beam 70 . Some of the locking components 164 may be suitable for being arranged at intervals along the length direction of the vehicle beam 70 , or all of the locking components 164 may be suitable for being arranged at intervals along the length direction of the vehicle beam 70 .

[0177] In the above technical solution, by making at least part of the locking components 164 suitable for being spaced apart along the length direction of the vehicle beam 70, at least part of the connection points between the battery 100 and the vehicle beam 70 can be spaced apart along the length direction of the vehicle beam 70, so that the battery 100 can be reliably and stably installed and fixed on the vehicle beam 70.

Alternatively, all of the locking components 164 are arranged on the outer edge of the load-bearing bracket 10 and are arranged at intervals along the circumference of the load-bearing bracket 10.

[0183] In the above technical solution, by arranging at least part of the locking parts 164 on the outer edge of the load-bearing bracket 10 and arranging them at intervals along the circumference of the load-bearing bracket 10, the battery 100 can be reliably and stably installed and fixed on the vehicle beam 70, and at least part of the connection points between the battery 100 and the vehicle beam 70 are located at the outer edge of the load-bearing bracket 10, which facilitates the locking and unlocking operations of the connection points between the battery 100 and the vehicle beam 70, thereby facilitating the removal of the battery 100 from the vehicle beam 70 or installation on the vehicle beam 70.

[0187] In some embodiments, referring to FIG. 1-FIG . 3 , a plurality of battery modules 20 are arranged in multiple layers in the vertical direction, and at least a portion of the locking member 164 is located between adjacent battery modules 20 in the uppermost layer.

[0188] Each layer may include one battery module 20 or multiple battery modules 20 .

Some of the locking components 164 may be located between the uppermost adjacent battery modules 20 , or all of the locking components 164 may be located between the uppermost adjacent battery modules 20 .

[0190] In the above technical solution, multiple battery modules 20 are arranged in multiple layers in the upper and lower directions, so that the arrangement of the battery modules 20 can be compact, which is beneficial to improving the energy density of the battery 100; and, by locating at least part of the locking accessories 164 between the adjacent battery modules 20 in the uppermost layer, while fully utilizing the gaps between the battery modules 20, it is also convenient to connect or disconnect the locking accessories 164 from the vehicle beam 70, thereby further facilitating the removal of the battery 100 from the vehicle beam 70 or installation on the vehicle beam 70.

[0191] In some embodiments, referring to Figures 1-4, the load-bearing bracket 10 includes a lower frame 11 and a plurality of support partitions 12, the plurality of support partitions 12 are arranged on the lower frame 11, at least part of the battery modules 20 are located between two adjacent support partitions 12, and at least part of the top of the support partitions 12 is provided with a locking accessory 164.

[0192] The lower frame 11 may be a bracket structure with a hollow structure, and the upper side of the lower frame 11 may be open.

[0193] At least some of the battery modules 20 are located between two adjacent supporting partitions 12 . Some of the battery modules 20 may be located between two adjacent supporting partitions 12 , or all of the battery modules 20 may be located between two adjacent supporting partitions 12 .

[0194] At least some of the support partitions 12 are provided with locking members 164 on their tops. Locking members 164 may be provided on the tops of some or all of the support partitions 12. A single support partition 12 may be provided with one locking member 164 on its top, or multiple locking members 164 may be provided on its top. Multiple locking members 164 are provided on a single support partition 12, and the multiple locking members 164 on a single support partition 12 are spaced apart along the extension direction of the support partition 12.

[0195] Optionally, some of the locking components 164 may be disposed on the top of the supporting partition 12 , or all of the locking components 164 may be disposed on the top of the supporting partition 12 .

[0196] In the above technical solution, by setting the load-bearing bracket 10 to include a lower frame 11 and multiple supporting partitions 12, the lower frame 11 can support the battery module 20, and the multiple supporting partitions 12 can separate adjacent battery modules 20, and can also limit the battery module 20, which also makes the structural strength of the entire load-bearing bracket 10 higher; and, a locking component 164 is provided on the top of the supporting partition 12, which can easily realize the setting of at least part of the locking component 164 between adjacent battery modules 20. Since at least part of the locking component 164 is provided on the top of the supporting partition 12, it is also convenient to lock and unlock the connection point between the battery 100 and the vehicle beam 70, thereby facilitating the removal of the battery 100 from the vehicle beam 70 or installation on the vehicle beam 70.

[0197] In some embodiments, referring to FIG. 1-FIG . 4 , a portion of the locking members 164 are disposed on the outer edge of the lower frame 11 and spaced apart along the circumference of the lower frame 11 , and a portion of the locking members 164 are disposed on the top of the supporting partition 12 .

[0198] In this embodiment, the setting of the locking accessories 164 may include the following situations: for example, a part of all the locking accessories 164 are arranged on the outer edge of the lower frame 11 and are arranged at intervals along the circumference of the lower frame 11, and the remaining locking accessories 164 are arranged at the top of the supporting partition 12; for another example, a part of the locking accessories 164 are arranged on the outer edge of the lower frame 11 and are arranged at intervals along the circumference of the lower frame 11, a part of the locking accessories 164 are arranged at the top of the supporting partition 12, and the remaining locking accessories 164 are arranged at other positions of the load-bearing bracket 10.

[0199] In the above technical solution, by arranging a part of the locking accessories 164 on the outer edge of the lower frame 11 and a part of the locking accessories 164 on the top of the supporting partition 12, whether it is the locking accessories 164 arranged on the outer edge of the lower frame 11 or the locking accessories 164 arranged on the top of the supporting partition 12, the locking accessories 164 are arranged at these positions, which can facilitate the locking and unlocking operations of the connection points between the battery 100 and the vehicle beam 70, thereby facilitating the removal of the battery 100 from the vehicle beam 70 or the installation of the battery 100 on the vehicle beam 70.

[0200] 3 and 4 , the plurality of support partitions 12 include a first support partition 13 and a second support partition 14 . The first support partition 13 is detachably connected to the lower frame 11 , and a locking member 164 is provided on the top of the second support partition 14 .

[0201] When assembling the battery 100, at least part of the battery module 20 can be placed in the lower frame 11 first, and then the first support partition 13 can be installed on the lower frame 11. Compared with first installing the first support partition 13 and then installing the battery module 20, the distance between the first support partition 13 and the battery module 20 can be very small, or the first support partition 13 and the bottom structure of the battery module 20 can be partially overlapped. This can make the arrangement between the battery modules 20 more compact and the installation of the battery module 20 is also convenient.

[0202] In the above technical solution, by making a part of the multiple support partitions 12 detachable, the installation and disassembly of the battery module 20 can be further facilitated, and the structure can be made more compact, reducing space waste, improving space utilization, and helping to improve the energy density of the battery 100; in addition, since the battery 100 is locked to the vehicle beam 70 through the locking accessory 164, the locking accessory 164 and the connection part of the load-bearing bracket 10 with the locking accessory 164 play a major load-bearing role. By providing the locking accessory 164 on the top of the second support partition 14 instead of providing the locking accessory 164 on the top of the first support partition 13, the installation position of the locking accessory 164 of the battery 100 can be a more reliable and stable position of the load-bearing bracket 10, thereby improving the stability and reliability of the battery 100 installed on the vehicle beam 70.

[0203] In some embodiments, the second support baffle 14 is integrally formed with the lower frame 11. This means that the second support baffle 14 and the lower frame 11 are integrally formed, and there is no boundary line or interface between the second support baffle 14 and the lower frame 11.

[0204] In the above technical solution, by integrally forming the second support partition 14 and the lower frame 11, the connection between the second support partition 14 and the lower frame 11 can be made more reliable, and the installation position of the locking accessory 164 of the battery 100 can be further made a more reliable and stable position of the load-bearing bracket 10, thereby improving the stability and reliability of the battery 100 installed on the vehicle beam 70, and also allowing the locking accessory 164 set on the second support partition 14 to better transfer the load to the lower frame 11 through the second support partition 14.

[0205] In some embodiments, referring to Figures 2-4, multiple battery modules 20 are arranged in two layers in the upper and lower directions, each layer includes multiple battery modules 20, the battery modules 20 located in the lower layer are located between adjacent support partitions 12, and the multiple battery modules 20 located in the upper layer are supported above the multiple support partitions 12, and the locking accessories 164 provided on the support partitions 12 are located between adjacent battery modules 20 in the upper layer.

[0206] When the plurality of battery modules 20 are arranged in two layers in the vertical direction, the one with a higher height position is the upper layer, and the one with a lower height position is the lower layer.

[0207] The multiple battery modules 20 located on the upper layer are supported above the multiple supporting partitions 12. The multiple battery modules 20 located on the upper layer can be directly supported above the multiple supporting partitions 12, in which case the bottom surfaces of the multiple battery modules 20 are directly in contact with the upper surfaces of the supporting partitions 12; or the multiple battery modules 20 located on the upper layer are indirectly supported above the multiple supporting partitions 12, in which case other supporting structures can be arranged between the bottom surfaces of the multiple battery modules 20 and the upper surfaces of the supporting partitions 12 to further improve the overall structural strength of the load-bearing bracket 10.

[0208] The supporting partition 12 can strengthen the structural strength of the lower frame 11 and support the battery module 20 on the upper layer.

[0209] In the above technical solution, multiple battery modules 20 are arranged in two layers in the upper and lower directions. While making the arrangement of the battery modules 20 compact and beneficial to improving the energy density of the battery 100, the overall height of the battery 100 will not be too high to affect the use scenario of the battery 100, so that the size of the battery 100 in the upper and lower directions is relatively appropriate. When the battery 100 is installed on the vehicle beam 70, the chassis of the vehicle 1000 can be avoided from being too low due to the excessive size of the battery 100 in the upper and lower directions. The supporting partition 12 can separate the adjacent battery modules 20 located in the lower layer, and can also limit the battery modules 20 in the lower layer. Furthermore, since the battery modules 20 located on the upper layer are supported by the multiple support partitions 12, the multiple support partitions 12 can support the battery modules 20 located on the upper layer, and the loads applied to the battery modules 20 located on the upper layer can be transmitted to the lower frame 11 through the multiple support partitions 12, thereby reducing the impact on the battery modules 20 located on the upper layer and also reducing the impact on the battery modules 20 located on the lower layer, thereby helping to extend the service life of the battery modules 20. In addition, by locating the locking members 164 of the support partitions 12 between adjacent battery modules 20 on the upper layer, the space between adjacent battery modules 20 on the upper layer can be fully utilized, making the overall structure of the battery 100 compact and facilitating the locking and unlocking operations of the locking members 164 and the vehicle beam 70, thereby facilitating the removal of the battery 100 from or installation of the vehicle beam 70.

[0210] 8 , the spacing between the battery modules 20 on opposite sides of the first support partition 13 is a first spacing L1, and the spacing between the battery modules 20 on opposite sides of the second support partition 14 is a second spacing L2, and the first spacing L1 is smaller than the second spacing L2.

[0211] The battery modules 20 located on two opposite sides of the first supporting partition 13 refer to the battery modules 20 located on two opposite sides of the first supporting partition 13 in the thickness direction.

[0212] The battery modules 20 located on two opposite sides of the second supporting partition 14 refer to the battery modules 20 located on two opposite sides in the thickness direction of the second supporting partition 14 .

[0213] When the vertical spacing between the battery modules 20 on opposite sides of the first support partition 13 is inconsistent, for example, the spacing between the battery modules 20 on opposite sides of the first support partition 13 increases from bottom to top; when the vertical spacing between the battery modules 20 on opposite sides of the second support partition 14 is inconsistent, for example, the spacing between the battery modules 20 on opposite sides of the second support partition 14 increases from bottom to top. In this case, the comparison between the first spacing and the second spacing refers to a comparison at the same height position, and the first spacing L1 being smaller than the second spacing L2 means that the first spacing is smaller than the second spacing at the same height position.

[0214] In the above technical solution, the detachable feature of the first support partition 13 can be utilized to make the distance between the battery modules 20 located on the opposite sides of the first support partition 13 smaller, which can make the structure more compact, reduce space waste, improve space utilization, and help improve the energy density of the battery 100.

[0215] In some embodiments, referring to Figures 8 and 9, the battery module 20 includes an outer shell 21 and a battery cell 221 arranged in the outer shell 21, the outer shell 21 includes a bottom plate 212 and a shell 211, the shell 211 is connected to the upper side of the bottom plate 212, and a accommodating cavity 201 for accommodating the battery cell 221 is defined between the shell 211 and the bottom plate 212, the bottom surface of the first support partition 13 is supported on the bottom plate 212 of the two adjacent battery modules 20 located in the lower layer, and the first support partition 13 is connected to the bottom plate 212, the bottom plate 212 is connected to the lower frame 11, and the bottom surface of the second support partition 14 is supported and connected to the lower frame 11.

[0216] The first supporting partition 13 is connected to the bottom plate 212, and the first supporting partition 13 and the bottom plate 212 are detachably connected. The bottom plate 212 is connected to the lower frame 11, and the bottom plate 212 and the lower frame 11 are detachably connected.

[0217] Optionally, the second supporting baffle 14 may be integrally formed with the lower frame 11 , or the second supporting baffle 14 may be welded to the lower frame 11 .

[0218] In the above technical solution, the battery module 20 can be sealed by its own outer shell 21, and the battery module 20 is supported and connected to the load-bearing bracket 10 by its own bottom plate 212, so that the battery module 20 can be stably supported by the load-bearing bracket 10; in addition, the bottom surface of the first support partition 13 is supported on the bottom plates 212 of the two adjacent battery modules 20 located in the lower layer, so that the first support partition 13 partially overlaps with the bottom plate 212 of the battery module 20, which can make full use of the space and reduce space waste, making the structure more compact, which is conducive to improving the energy density of the battery 100, and the first support partition 13 is connected to the bottom plate 212 of the battery module 20 located in the lower layer, which can make the overall structure stronger and more stable.

[0219] 8 and 9 , the first fastener 161 penetrates the first supporting partition 13 , the bottom plate 212 , and the lower frame 11 to mount the battery module 20 and the first supporting partition 13 on the lower frame 11 .

[0220] The first fastener 161 may be a threaded fastener, or a bolt.

[0221] In the above technical solution, the first fasteners 161 are inserted through the first support partition 13, the bottom plate 212, and the lower frame 11, thereby achieving a removable connection between the battery module 20 located on the lower layer and the load-bearing bracket 10. Furthermore, the fastener connection method connects the battery module 20 to the lower frame 11, ensuring the installation stability and reliability of the battery module 20 located on the lower layer and facilitating the assembly and disassembly of the battery module 20 located on the lower layer. Furthermore, the first support partition 13 and the bottom plate 212 share the first fasteners 161, which secure the first support partition 13 and the battery module 20 located on the lower layer to the lower frame 11, reducing the number of fasteners and improving assembly and disassembly efficiency.

[0222] In some embodiments, referring to Figures 8-12, a hollow cavity 131 is formed in the first support partition 13, an avoidance hole 132 communicating with the hollow cavity 131 is formed at the top of the first support partition 13, and a connecting hole 133 is formed at the bottom of the first support partition 13. The connecting hole 133 is opposite to the avoidance hole 132 in the upper and lower directions, and the first fastener 161 is suitable for passing through the avoidance hole 132 and the hollow cavity 131 and downwardly penetrating into the connecting hole 133, the bottom plate 212 and the lower frame 11.

[0223] In the process of installing and fixing the first support partition 13 and part of the battery modules 20 located on the lower layer to the lower frame 11 through the first fastener 161, the first fastener 161 can pass downward through the avoidance hole 132 and extend into the hollow cavity 131, and then extend into the connecting hole 133 at the bottom of the first support partition 13 through the hollow cavity 131, and pass downward through the bottom plate 212 and the lower frame 11. The lower end of the first fastener 161 can extend downward from the bottom surface of the lower frame 11. When the first fastener 161 is a bolt, it is convenient to install the nut to cooperate with the first fastener 161 to tighten the first fastener 161 to the lower frame 11.

[0224] In the above technical solution, by setting the first support partition 13 as a hollow structure, the material consumption and weight can be reduced while ensuring the structural strength of the first support partition 13; and, by setting an avoidance hole 132 on the top of the first support partition 13, it is convenient to pass the first fastener 161 downward through the avoidance hole 132 to the hollow cavity 131 to connect the first support partition 13, the bottom plate 212 and the lower frame 11.

[0225] In some embodiments, referring to Figures 8-11, the load-bearing bracket 10 includes an upper bracket 15, which is supported on the upper surface of multiple support partitions 12, and the upper bracket 15 is connected to the multiple support partitions 12. The battery module 20 located on the upper layer is supported on the upper bracket 15, and the battery module 20 located on the upper layer is connected to the upper bracket 15.

[0226] The upper bracket 15 may be a bracket with an integral structure. When the upper bracket 15 is a bracket with an integral structure, the upper bracket 15 may be a bracket with a hollow structure. The upper bracket 15 may generally be a plate-shaped bracket with a hollow structure.

[0227] The upper bracket 15 may also be a split structure including a plurality of spaced-apart sub-brackets 151. The sub-brackets 151 may be in the shape of an elongated strip. The plurality of sub-brackets 151 may be arranged in a direction perpendicular to the arrangement direction of the plurality of support baffles 12. For example, the plurality of support baffles 12 may be arranged in a first direction, and the plurality of sub-brackets 151 may be arranged in a second direction perpendicular to the first direction. Each sub-bracket 151 may be connected to all the support baffles 12.

[0228] The connection between the battery module 20 located on the upper layer and the upper bracket 15 can be a detachable connection.

[0229] In the above technical solution, by providing an upper bracket 15 for supporting and fixing the battery module 20 located on the upper layer, the installation and fixation of the battery module 20 located on the upper layer is facilitated, and the structural strength of the load-bearing bracket 10 can be improved.

[0230] In some embodiments, referring to Figures 8 and 9, the battery module 20 includes an outer shell 21 and a battery cell 221 disposed in the outer shell 21. The outer shell 21 includes a base plate 212 and a shell 211. The shell 211 is connected to the upper side of the base plate 212. A accommodating cavity 201 for accommodating the battery cell 221 is defined between the shell 211 and the base plate 212. The second fastener 162 is suitable for passing through the base plate 212 and the upper bracket 15 to install the battery module 20 located on the upper layer on the upper bracket 15.

[0231] The second fastener 162 may be a threaded fastener, for example, the second fastener 162 may be a screw.

[0232] In the above technical solution, the second fastener 162 is passed through the bottom plate 212 and the upper bracket 15, so that the battery module 20 located on the upper layer and the load-bearing bracket 10 can be detachably connected; and the connection method of the fastener realizes the detachable connection between the battery module 20 and the upper bracket 15, which can ensure the installation stability and reliability of the battery module 20 located on the upper layer, and also makes it easy to disassemble and assemble the battery module 20 on the upper layer.

[0233] In some embodiments, referring to Figures 10 and 11, multiple support partitions 12 are arranged at intervals along a first direction, and the support partitions 12 extend along a second direction. The first direction is parallel to the length direction of the vehicle beam 70, the second direction is parallel to the width direction of the vehicle beam 70, the second direction is perpendicular to the first direction, and the second direction and the first direction are both parallel to the horizontal direction.

[0234] In the above technical solution, by arranging multiple support partitions 12 at intervals along the length direction of the vehicle beam 70 and extending the support partitions 12 in the length direction perpendicular to the vehicle beam 70, the multiple support partitions 12 of the load-bearing bracket 10 can bear weight in the form of "carrying a shoulder pole", which can better reduce the vibration impact on the battery module 20; and, the load on the battery module 20 located on the upper layer can be better transmitted to the lower frame 11 through the multiple support partitions 12, reducing the impact on the battery module 20 located on the upper layer, and also reducing the impact on the battery module 20 located on the lower layer, which is beneficial to extending the service life of the battery module 20.

[0235] In some embodiments, referring to Figures 13 and 14, there are multiple battery modules 20, and the multiple battery modules 20 are arranged in multiple layers in the up and down directions. The load-bearing bracket 10 includes multiple sub-load-bearing brackets 17 arranged along the up and down directions. Each sub-load-bearing bracket 17 is used to bear the weight of the corresponding layer or layers of battery modules 20. The sub-load-bearing bracket 17 located at the top is provided with a locking accessory 164, and the remaining sub-load-bearing brackets 17 are detachably connected to adjacent sub-load-bearing brackets 17.

[0236] Each sub-load-bearing bracket 17 is used to support the weight of one or more layers of battery modules 20. The number of sub-load-bearing brackets 17 can be the same as the number of battery modules 20 layers, or the number of sub-load-bearing brackets 17 can be less than the number of battery modules 20 layers. When the number of sub-load-bearing brackets 17 is the same as the number of battery modules 20 layers and the number of sub-load-bearing brackets 17 is one-to-one, each sub-load-bearing bracket 17 is used to support the weight of a corresponding layer of battery modules 20. When the number of sub-load-bearing brackets 17 is less than the number of battery modules 20 layers, the following situations may occur: for example, some sub-load-bearing brackets 17 are used to support the weight of one layer of battery modules 20, while other sub-load-bearing brackets 17 are used to support the weight of at least two layers of battery modules 20; or as another example, each sub-load-bearing bracket 17 is used to support the weight of at least two layers of battery modules 20.

[0237] The structures of the multiple sub-load-bearing brackets 17 may be different. For example, the structural strength of the lower sub-load-bearing bracket 17 of two adjacent sub-load-bearing brackets 17 is greater than the structural strength of the upper sub-load-bearing bracket 17 .

[0238] In the above technical solution, multiple battery modules 20 are arranged in multiple layers in the up and down directions, so that the battery modules 20 can be arranged compactly, which is beneficial to improving the energy density of the battery 100; and, by setting the load-bearing bracket 10 as multiple sub-load-bearing brackets 17 along the up and down directions, and each sub-load-bearing bracket 17 is used to support the weight of the corresponding layer or layers of battery modules 20, all battery modules 20 are stably supported, and at the same time, the sub-load-bearing bracket 17 located at the top is provided with a locking accessory 164 connected to the vehicle beam 70 and the remaining sub-load-bearing brackets 17 are detachably connected to the adjacent sub-load-bearing brackets 17, so that part or all of the battery 100 can be removed from the vehicle beam 70, making the disassembly and assembly of the battery 100 more flexible and convenient.

[0239] 13 and 14 , two adjacent sub-load-bearing brackets 17 are connected by locking members 165 . The locking members 165 are provided on the outer edge of the sub-load-bearing bracket 17 and are spaced apart along the circumference of the sub-load-bearing bracket 17 .

[0240] In the above technical solution, by connecting two adjacent sub-load-bearing brackets 17 through a locking member 165, the locking and unlocking of the two adjacent sub-load-bearing brackets 17 are facilitated, thereby facilitating the disassembly and assembly of some battery modules 20. In addition, by arranging multiple locking members 165 at intervals along the circumference of the sub-load-bearing bracket 17, a reliable connection of adjacent sub-load-bearing brackets 17 can be achieved. The locking member 165 is arranged on the outer edge of the sub-load-bearing bracket 17, which facilitates the locking and unlocking operations of the connection points between adjacent sub-load-bearing brackets 17.

[0241] In some embodiments, referring to FIG. 13 and FIG. 14 , the plurality of battery modules 20 are arranged in two layers in the vertical direction, and the sub-load-bearing bracket 17 located below is provided with a locking member 165 and a locking member 164 .

[0242] The upper sub-load-bearing bracket 17 is provided with a locking member 164 , and the upper sub-load-bearing bracket 17 may not be provided with a locking member 165 .

[0243] In the above technical solution, the plurality of battery modules 20 are arranged in two layers in the vertical direction. This makes the arrangement of the battery modules 20 compact, which is beneficial to improving the energy density of the battery 100. At the same time, the overall height of the battery 100 is not too high, which affects the use scenario of the battery 100. The size of the battery 100 in the vertical direction is relatively appropriate. When the battery 100 is installed on the vehicle beam 70, it can avoid the chassis of the vehicle 1000 being too low due to the excessive size of the battery 100 in the vertical direction. In addition, the lower sub-load-bearing bracket 17 is provided with a locking member 165 and a locking member 164. The lower sub-load-bearing bracket 17 can be detachably connected to the upper sub-load-bearing bracket 17, and the lower sub-load-bearing bracket 17 and the vehicle beam 70 also have a detachable connection point, further improving the lower sub-load-bearing bracket 17 and the corresponding lower layer of battery modules 20. It can also reduce the force borne by the upper sub-load-bearing bracket 17.

[0244] In some embodiments, referring to Figure 1, the vehicle beam 70 includes: a vehicle beam body 701 and a connecting bracket 702, the connecting bracket 702 is connected to opposite sides of the vehicle beam body 701 in the width direction, and the load-bearing bracket 10 is at least suitable for detachable connection with the connecting bracket 702 in the vehicle beam 70.

[0245] The connecting bracket 702 and the vehicle beam main body 701 may be connected by welding or by fasteners; the connecting bracket 702 and the vehicle beam main body 701 may also be integrally formed.

[0246] The load-bearing bracket 10 is at least suitable for being detachably connected to the connecting bracket 702 in the vehicle beam 70, including the following situations: for example, the load-bearing bracket 10 is detachably connected to the connecting bracket 702 in the vehicle beam 70; for another example, the load-bearing bracket 10 is detachably connected to the connecting bracket 702 in the vehicle beam 70 and the load-bearing bracket 10 is detachably connected to the vehicle beam main body 701 in the vehicle beam 70.

[0247] In the above technical solution, by configuring the vehicle beam 70 to include a vehicle beam body 701 and connecting brackets 702 connected to both sides of the vehicle beam body 701 in the width direction, the load-bearing bracket 10 of the battery 100 is conveniently connected to the vehicle beam 70 .

[0248] In some embodiments, referring to Figures 1 and 2, a plurality of locking accessories 164 are provided on the load-bearing bracket 10 at intervals, a portion of the locking accessories 164 is suitable for detachable connection with the vehicle beam body 701 and another portion of the locking accessories 164 is suitable for detachable connection with the connecting bracket 702 to lock the battery 100 to the vehicle beam 70.

[0249] In the above technical solution, by providing a plurality of locking elements 164 on the load-bearing bracket 10, the battery 100 can be conveniently and reliably mounted and fixed to the beam 70 of the vehicle body 200. This also facilitates removal of the battery 100 from or installation of the beam 70, thereby facilitating maintenance and replacement of the battery 100. Furthermore, by detachably connecting a portion of the locking elements 164 to the beam body 701 and another portion of the locking elements 164 to the connecting bracket 702, more connection points can be provided between the load-bearing bracket 10 of the battery 10 and the beam 70. Furthermore, these multiple connection points cover a wider area, thereby improving the stability and reliability of the connection between the battery 100 and the beam 70.

[0250] In some embodiments, referring to Figures 1 and 2, there are multiple battery modules 20, a portion of the locking accessories 164 is located between adjacent battery modules 20 and is suitable for detachable connection with the vehicle beam body 701, and another portion of the locking accessories 164 is arranged on the outer edge of the load-bearing bracket 10 and is suitable for detachable connection with the connecting bracket 702.

[0251] In the above technical solution, part of the locking component 164 is located between adjacent battery modules 20, which can make full use of the gap between the battery modules 20, making the overall structure of the battery 100 compact and facilitating the connection of part of the locking component 164 to the vehicle beam body 701; at the same time, another part of the locking component 164 is arranged on the outer edge of the load-bearing bracket 10, so that the battery 100 can be reliably and stably installed on the connecting bracket 702, making it convenient to lock and unlock the connection point between the battery 100 and the connecting bracket 702, thereby facilitating the removal of the battery 100 from the vehicle beam 70 or installation on the vehicle beam 70.

[0252] In some embodiments, referring to Figures 1 and 2, there are multiple battery modules 20, some of which are located in the first beam space 73 defined by the vehicle beam body 701, and some of the battery modules 20 are located in the second beam space 74 defined by the connecting bracket 702.

[0253] In the above technical solution, by locating part of the battery modules 20 in the first beam space 73 defined by the vehicle beam main body 701, the space in the vehicle beam main body 701 can be fully utilized, and by locating part of the battery modules 20 in the second beam space 74 defined by the connecting bracket 702, the space in the connecting bracket 702 can be fully utilized, so that at least part of the battery 100 can be located in the space defined by the vehicle beam 70, thereby fully utilizing the space of the vehicle beam 70 itself, making the installation of the battery 100 and the vehicle beam 70 more compact. When the height dimensions of the battery 100 in the upper and lower directions are constant, when the battery 100 is installed on the vehicle beam 70, the position of the bottom surface of the battery 100 is higher, avoiding scratches during the operation of the vehicle 1000 due to the battery 100 being too low, which is beneficial to reducing damage to the battery 100 and extending the service life of the battery 100.

[0254] In some embodiments, referring to FIG. 1 and FIG. 2 , the battery 100 includes a docking device 52 . The docking device 52 is disposed on the load-bearing bracket 10 . The docking device 52 is at least used to achieve electrical connection between the battery 100 and the vehicle body 200 .

[0255] When the battery 100 is installed on the vehicle beam 70, the docking connector 52 of the battery 100 is electrically connected to the corresponding structure on the vehicle body 200. The battery 100 is electrically connected to the vehicle body 200 through the docking connector 52, so that the battery 100 can be used to provide a power source for the vehicle 1000, serving as the driving power of the vehicle 1000 and the power source for other electrical components.

[0256] In the above technical solution, by arranging a docking device 52 on the load-bearing bracket 10, it is convenient to achieve electrical connection between the battery 100 and the vehicle body 200 when the battery 100 is installed on the vehicle body 200, and it is also convenient to disconnect the battery 100 from the vehicle body 200 when the battery 100 is removed from the vehicle body 200.

[0257] 1-4 , in some embodiments, the docking connector 52 is located on top of the battery 100. Positioning the docking connector 52 on top of the battery 100 facilitates docking of the docking connector 52 with corresponding structures on the vehicle body 200 when the battery 100 is mounted on the vehicle beam 70, thereby conveniently achieving electrical connection between the docking connector 52 and the vehicle body 200. Furthermore, when the battery 100 is removed from the vehicle beam 70, the docking connector 52 is easily separated from the corresponding structures on the vehicle body 200.

[0258] In some embodiments, referring to Figures 1-4, the docking port 521 of the docking connector 52 faces upward. By placing the docking connector 52 on top of the battery 100, when the battery 100 is mounted on the vehicle beam 70, the docking connector 52 and the corresponding structure on the vehicle body 200 are docked in the vertical direction, thereby conveniently achieving electrical connection between the docking connector 52 and the vehicle body 200. Furthermore, when the battery 100 is removed from the vehicle beam 70, the docking connector 52 and the corresponding structure on the vehicle body 200 are separated in the vertical direction, which also facilitates separation of the docking connector 52 from the corresponding structure on the vehicle body 200.

[0259] 1-4 , the docking connector 52 is located in the middle of the load-bearing bracket 10 in the width direction of the vehicle beam 70. By arranging the docking connector 52 in the middle of the load-bearing bracket 10 in the width direction of the vehicle beam 70, the effects of vibration, shock, or natural load-bearing deformation on the docking connector 52 can be reduced.

[0260] In some embodiments, referring to FIG. 2 to FIG. 5 , the battery 100 includes: a distribution box 50 , the distribution box 50 is disposed on the load-bearing bracket 10 , and a docking device 52 is disposed on the distribution box 50 .

[0261] Among them, the distribution box 50 is the battery 100 energy distribution unit of the battery 100, all battery modules 20 are electrically connected to the distribution box 50, and the distribution box 50 and the vehicle body 200 are electrically connected through the docking device 52. The distribution box 50 and the docking device 52 provided in the distribution box 50 are components for electrically connecting the battery 100 and the vehicle body 200, so that the battery 100 can supply power to the vehicle body 200.

[0262] In the above technical solution, by arranging the docking connector 52 in the distribution box 50 , the electrical connection distance between the docking connector 52 and the distribution box 50 can be shortened, and the length of the corresponding connection harness can be reduced.

[0263] In some embodiments, at least some of the battery modules 20 are detachably connected to the distribution box 50 via a connecting harness.

[0264] At least some of the battery modules 20 are detachably connected to the distribution box 50 via a connecting harness. For example, some of the battery modules 20 are detachably connected to the distribution box 50 via a connecting harness, or each battery module 20 is detachably connected to the distribution box 50 via a connecting harness.

[0265] Among them, the battery module 20 detachably connected to the load-bearing bracket 10 (referring to the battery module 20 detachably connected to the load-bearing bracket 10) is detachably connected to the distribution box 50 through a connecting harness.

[0266] In the above technical solution, the detachable connection between at least part of the battery module 20 and the distribution box 50 is achieved by connecting the wiring harness, which not only enables the disassembly of the mechanical connection structure of the battery module 20, but also enables the disassembly of the electrical connection structure of the battery module 20, so that the battery module 20 can be removed smoothly as a whole.

[0267] In some embodiments, referring to Figures 2-5, at least part of the battery modules 20 have a first interface 23, the distribution box 50 has a second interface 51, the two ends of the connecting harness are respectively connected to the first interface 23 and the second interface 51, and the connecting harness is detachably connected to at least one of the first interface 23 and the second interface 51.

[0268] A single battery module 20 can have two first interfaces 23, one of which is a positive electrode and the other is a negative electrode. The distribution box 50 has an even number of second interfaces 51 and at least one pair of second interfaces 51, one of which is a positive electrode and the other is a negative electrode. The first interfaces 23 of the battery modules 20 and the second interfaces 51 of the distribution box 50 can be connected according to the required series-parallel connection method of the multiple battery modules 20.

[0269] For example, if all battery modules 20 are connected in parallel, the first interface 23 serving as the positive pole in each battery module 20 is connected to the second interface 51 serving as the positive pole in the distribution box 50 through a connecting wiring harness, and the first interface 23 serving as the negative pole in each battery module 20 is connected to the second interface 51 serving as the negative pole in the distribution box 50 through a connecting wiring harness.

[0270] For another example, all the battery modules 20 are connected in series in sequence, and the first interfaces 23 with opposite polarities in two adjacent battery modules 20 are connected, the first interface 23 as the positive pole in one of the battery modules 20 is connected to the second interface 51 as the positive pole in the distribution box 50, and the first interface 23 as the negative pole in one of the battery modules 20 is connected to the second interface 51 as the negative pole in the distribution box 50.

[0271] For another example, multiple battery modules 20 can be mixed in series. For example, multiple batteries 100 can be divided into multiple groups, each group includes at least two battery modules 20, the two battery modules 20 in each group are connected in series, the first interfaces 23 with opposite polarities in the two battery modules 20 in each group are connected, and the remaining first interfaces 23 in the two battery modules 20 in each group are connected to the second interfaces 51 with corresponding polarity in the distribution box 50.

[0272] At least some of the battery modules 20 have the first interface 23 , and some or all of the battery modules 20 may have the first interface 23 . The battery modules 20 detachably connected to the distribution box 50 via the connecting harness have the first interface 23 .

[0273] The detachable connection between the connecting harness and at least one of the first interface 23 and the second interface 51 may include the following situations: for example, the connecting harness may be detachably connected to the first interface 23, so that the battery module 20 and the distribution box 50 can be detachably connected through the connecting harness by connecting the connecting harness to the first interface 23 or removing it from the first interface 23; for another example, the connecting harness may be detachably connected to the second interface 51, so that the battery module 20 and the distribution box 50 can be detachably connected through the connecting harness by connecting the connecting harness to the second interface 51 or removing it from the second interface 51; for another example, the connecting harness may be detachably connected to the first interface 23 and the connecting harness may be detachably connected to the second interface 51, so that the battery module 20 and the distribution box 50 can be detachably connected through the connecting harness by connecting the connecting harness to the first interface 23 or removing it from the first interface 23, or by connecting the connecting harness to the second interface 51 or removing it from the second interface 51.

[0274] The detachable connection method between the connecting wire harness and the first interface 23 can be a plug-in connection, for example, one end of the connecting wire harness has a first plug-in terminal, and the first plug-in terminal can be plugged into the first interface 23; similarly, the detachable connection method between the connecting wire harness and the second interface 51 can be a plug-in connection, for example, the other end of the connecting wire harness has a second plug-in terminal, and the second plug-in terminal can be plugged into the second interface 51.

[0275] In the above technical solution, by providing interfaces between the battery module 20 and the distribution box 50 , the connection and separation between the battery module 20 and the distribution box 50 are further facilitated.

[0276] In some embodiments, referring to FIG. 2 to FIG. 5 , the distribution box 50 has a plurality of second interfaces 51 , and all the second interfaces 51 are located on the same side of the distribution box 50 .

[0277] All the second interfaces 51 are located on the same side of the distribution box 50 , which means that all the second interfaces 51 are located on the same side of the distribution box 50 in the horizontal direction.

[0278] In the above technical solution, by setting multiple second interfaces 51 on the distribution box 50 on the same side of the distribution box 50, multiple connection harnesses of multiple battery modules 20 can be conveniently connected to the same side of the distribution box 50, making it easy to disassemble and assemble the connection harnesses, and also convenient for maintenance.

[0279] In some embodiments, referring to FIG. 2-FIG . 5 , the distribution box 50 is integrated with one of the battery modules 20 .

[0280] The distribution box 50 and one of the battery modules 20 are integrated into one body, which means that the distribution box 50 and one of the battery modules 20 are integrated into an integral structure.

[0281] In the above technical solution, by integrating the distribution box 50 with one of the battery modules 20, the structure can be made compact, the occupied space can be reduced, and the overall energy density of the battery 100 can be improved.

[0282] In some embodiments, referring to Figures 1-4, the multiple battery modules 20 include a first battery module 30 and a second battery module 40, there is at least one first battery module 30, and there is one second battery module 40. The first battery module 30 and the distribution box 50 are detachably connected through a connecting harness, and the distribution box 50 and the second battery module 40 are integrated into one.

[0283] There is at least one first battery module 30 , which means there can be one or more first battery modules 30 . At least one first battery module 30 can be detachably mounted on the load-bearing bracket 10 .

[0284] It is understandable that since the distribution box 50 is integrated with the second battery module 40, the second battery module 40 may not be provided with the above-mentioned first interface 23, and the battery cells 221 of the second battery module 40 can be directly electrically connected to the distribution box 50 inside the second battery module 40.

[0285] The distribution box 50 and the second battery module 40 are integrated into one body, meaning that the distribution box 50 and the second battery module 40 are integrated into a single unit. The second battery module 40 can be detachably mounted on the load-bearing bracket 10. Since the distribution box 50 and the second battery module 40 are integrated into one body, the distribution box 50 and the second battery module 40 can be removed from the load-bearing bracket 10 as a whole, or can be installed onto the load-bearing bracket 10 as a whole.

[0286] In some embodiments, referring to Figures 2-5, the battery module 20 includes a shell 21 and a battery cell 221 disposed in the shell 21, the shell 21 of the first battery module 30 is provided with a first interface 23, the distribution box 50 includes a box body and an electrical component disposed in the box body, the shell 21 of the second battery module 40 constitutes the box body and the shell 21 of the second battery module 40 is provided with a second interface 51, the electrical component is electrically connected to the second interface 51, the two ends of the connecting harness are respectively connected to the first interface 23 and the second interface 51, the connecting harness is detachably connected to at least one of the first interface 23 and the second interface 51, and the battery cell 221 of the second battery module 40 is electrically connected to the electrical component.

[0287] The outer shell 21 of the second battery module 40 constitutes a box body, and part of the outer shell 21 of the second battery module 40 may constitute the box body.

[0288] The second interface 51 is electrically connected to the electrical component. For example, the second interface 51 and the electrical component can be electrically connected through an internal wiring harness. The internal wiring harness is routed inside the box. The battery cells 221 of the second battery module 40 and the electrical components of the distribution box 50 are all located inside the outer shell 21 of the second battery module 40. In this way, the battery cells 221 of the second battery module 40 or the battery pack composed of multiple battery cells 221 can be directly electrically connected to the electrical components inside the outer shell 21 of the second battery module 40.

[0289] The electrical connection between the first battery module 30 and the distribution box 50 is achieved by connecting the first interface 23 and the second interface 51 via a wiring harness. It should be noted that the connection between the multiple first battery modules 30 and between the first battery modules 30 and the distribution box 50 can be determined based on the series and parallel connection of the multiple battery modules 20. For example, some of the first battery modules 30 can be connected in series before being electrically connected to the distribution box 50.

[0290] For example, when the battery 100 includes multiple first battery modules 30 and one second battery module 40, the multiple battery modules 20 of the battery 100 can be connected in series and parallel as follows: the multiple first battery modules 30 are divided into multiple module groups, the second battery module 40 includes multiple battery cells 221, and the multiple second battery cells 221 of the second battery module 40 are divided into multiple battery groups. The number of module groups is the same as the number of battery groups and corresponds one to one. Each module group includes multiple battery modules 20. After the multiple battery modules 20 of each module group are connected in series in sequence, the first interface 23 and the second interface 51 of the distribution box 50 are connected by a connecting harness to realize the electrical connection between the module group and the distribution box 50. The multiple battery groups of the second battery module 40 are all electrically connected to the electrical components of the distribution box 50, and through circuit design, each module group is connected in series with the corresponding battery group to form a battery branch, thereby forming multiple battery branches connected in parallel.

[0291] In the above technical solution, since the second battery module 40 is integrated with the distribution box 50, the structure is made compact, the occupied space is reduced, and it is beneficial to improve the overall energy density of the battery 100. At the same time, by making the distribution box 50 share the outer shell 21 of the second battery module 40 to achieve sealing of the distribution box 50, it is possible to eliminate the need to set up a separate box body for the distribution box 50, reduce the number of parts, and further make the structure compact, further reducing the occupied space; in addition, the battery cells 221 in the second battery module 40 can be electrically connected to the electrical components of the distribution box 50 in the outer shell 21 of the second battery module 40, thereby eliminating the need to set up an interface for connecting to the distribution box 50 on the outside of the second battery module 40.

[0292] In some embodiments, referring to Figures 2-5, the battery 100 includes: a thermal management system, the thermal management system includes multiple thermal management components 24, the battery module 20 includes a shell 21 and a battery cell 221 arranged in the shell 21, and the thermal management component 24 is arranged in the shell 21 or in the shell 21 for regulating the temperature of the battery cell 221.

[0293] Among them, the thermal management component 24 is used to adjust the temperature of the battery cell 221, including at least one of the thermal management component 24 being used to increase the temperature of the battery cell 221 and being used to reduce the temperature of the battery cell 221. For example, the thermal management component 24 can be used to increase the temperature of the battery cell 221 and can be used to reduce the temperature of the battery cell 221.

[0294] The thermal management component 24 is used to adjust the temperature of the battery cell 221 . The thermal management component 24 can be in thermal contact with the battery cell 221 to enable the thermal management component 24 to adjust the temperature of the battery cell 221 .

[0295] Optionally, the number of thermal management components 24 is the same as the number of battery modules 20 and corresponds one to one.

[0296] In the above technical solution, by setting up a thermal management system including multiple thermal management components 24, the temperature of each battery module 20 can be adjusted. By setting the thermal management component 24 in the outer shell 21 of the battery module 20, the battery module 20 has a separate thermal management component 24, which can improve the temperature adjustment efficiency of the thermal management component 24 on the battery cells 221 of the battery module 20 and facilitate the maintenance of the battery module 20.

[0297] In some embodiments, referring to FIG. 5-7 , the thermal management component 24 is integrated into the housing 21 .

[0298] The thermal management component 24 may be integrated into the housing 21 , which means that the thermal management component 24 and the housing 21 are integrated into a whole.

[0299] In the above technical solution, the thermal management component 24 is integrated into the housing 21 , which can make the structure of the battery module 20 compact, reduce the occupied space, and help improve the energy density of the single battery module 20 .

[0300] In some embodiments, the housing 21 includes a base plate 212 and a shell 211, the shell 211 is connected to the upper side of the base plate 212, and a accommodating cavity 201 for accommodating a battery cell 221 is defined between the shell 211 and the base plate 212, the base plate 212 is supported on a load-bearing bracket 10, and the thermal management component 24 is integrated in the base plate 212.

[0301] The thermal management component 24 is integrated with the base plate 212, meaning that the thermal management component 24 and the base plate 212 are integrated into one body, and the thermal management component 24 and the base plate 212 can jointly support the battery cells 221 of the battery module 20. For example, the base plate 212 can have a hollow structure, and the hollow structure in the base plate 212 can include the aforementioned heat exchange channel.

[0302] In the above technical solution, the battery module 20 is supported and connected to the load-bearing bracket 10 through its own base plate 212, so that the battery module 20 can be stably supported by the load-bearing bracket 10, and the battery module 20 can be more reliably fixed on the load-bearing bracket 10; and the thermal management component 24 is integrated into the base plate 212 to improve the structural strength of the base plate 212, so that the base plate 212 can better support the battery cells 221 located in the outer shell 21, and the overall center of gravity of the battery module 20 is lowered, making the overall structure of the battery module 20 more stable, and also making the battery module 20 more stably installed on the load-bearing bracket 10.

[0303] In some embodiments, referring to FIG. 5-7 , the thermal management component 24 is integrally formed with the base plate 212 .

[0304] The thermal management component 24 and the base plate 212 are integrally formed, which means that the thermal management component 24 and the base plate 212 form an integrated structure, and there is no boundary line or interface between the thermal management component 24 and the base plate 212 .

[0305] For example, the thermal management component 24 and the base plate 212 may be integrally cast.

[0306] In the above technical solution, by integrally forming the thermal management component 24 and the base plate 212 of the battery module 20, the number of parts can be reduced, the assembly process of the thermal management component 24 and the base plate 212 can be omitted, and production efficiency can be improved.

[0307] In some embodiments, referring to Figure 2, the thermal management component 24 has a heat exchange channel for the flow of heat exchange medium, and multiple thermal management components 24 are connected in series, parallel or mixed. The thermal management system also includes a thermal management connector 60, which is used to realize the thermal management flow path connection between the battery 100 and the vehicle body 200. The thermal management connector 60 is provided on the load-bearing bracket 10 and is located outside the battery module 20. At least part of the thermal management components 24 is connected to the thermal management connector 60.

[0308] The thermal management component 24 has a heat exchange channel for a heat exchange medium to flow through. During the flow of the heat exchange medium in the heat exchange channel, the heat exchange medium can remove heat from the battery cells 221, or the heat exchange medium can transfer heat to the battery cells 221 to heat the battery cells 221. The heat exchange medium can be a liquid heat exchange medium, for example, the heat exchange medium can include water.

[0309] The thermal management joint 60 may have two liquid inlets and outlets 61. The heat exchange medium flows into the thermal management joint 60 through one of the two liquid inlets and outlets 61, flows through the heat exchange channel, and then flows into the thermal management joint 60 again, and can flow out through the other of the two liquid inlets and outlets 61. When the thermal management joint 60 is connected to the thermal management flow path of the vehicle body 200 to form a circulation flow path, the two liquid inlets and outlets 61 of the thermal management joint 60 are connected to the thermal management flow path of the vehicle body 200 to form a circulation flow path.

[0310] When multiple thermal management components 24 are connected in series, the heat exchange medium flowing in from the thermal management joint 60 can flow through the multiple thermal management components 24 in sequence, and then flow out from the thermal management joint 60; when multiple thermal management components 24 are connected in parallel, the heat exchange medium flowing in from the thermal management joint 60 can flow through the multiple thermal management components 24 at the same time, and finally converge to the thermal management joint 60 before flowing out; when multiple thermal management joints 60 are mixed in series, for example, multiple thermal management joints 60 are divided into multiple thermal management groups, each thermal management group includes multiple thermal management components 24 connected in series, the heat exchange medium flowing in from the thermal management joint 60 can flow through the multiple thermal management groups at the same time, and when flowing through each thermal management group, it can flow through the multiple thermal management components 24 in each thermal management group in sequence, and finally converge to the thermal management joint 60 before flowing out.

[0311] In the above technical solution, the thermal management flow path of the battery 100 and the vehicle body 200 is connected by a plurality of thermal management components 24 sharing a thermal management connector 60. The heat exchange medium can flow into or out of the plurality of thermal management components 24 through a common thermal management connector 60, making it convenient for the thermal management system to be connected to the thermal management flow path of the vehicle body 200 through a common thermal management connector 60 to realize the circulation flow of the heat exchange medium.

[0312] In some embodiments, referring to FIG. 2 , the thermal management joint 60 is located near the outer edge of the load-bearing bracket 10 .

[0313] The outer edge of the load-bearing bracket 10 refers to the outer edge of the load-bearing bracket 10 in the horizontal direction.

[0314] In the above technical solution, by arranging the thermal management connector 60 close to the outer edge of the load-bearing bracket 10 , it is convenient to connect or separate the thermal management system of the battery 100 and the thermal management flow path of the vehicle body 200 .

[0315] In some embodiments, the thermal management component 24 and the thermal management connector 60 are detachably connected; and / or, the thermal management components 24 are detachably connected to each other.

[0316] Among them, when multiple thermal management components 24 are connected in series, the two adjacent thermal management components 24 can be detachably connected, and the two thermal management components 24 at the first two ends of the series path are respectively detachably connected to the thermal management joint 60; when multiple thermal management components 24 are connected in parallel, each thermal management component 24 is detachably connected to the thermal management joint 60; when multiple thermal management joints 60 are mixed, the thermal management components 24 connected in series can be detachably connected, and the remaining thermal management components 24 that need to be connected to the thermal management joint 60 are all detachably connected to the thermal management joint 60.

[0317] In the above technical solution, through the detachable connection between the thermal management component 24 and the thermal management connector 60 and / or the detachable connection between the thermal management components 24, not only the mechanical connection structure of the battery module 20 can be disassembled, but also the battery module 20 in the thermal management flow path can be disassembled, so that the battery module 20 as a whole can be smoothly disassembled.

[0318] In some embodiments, referring to Figures 5-7, the outer wall of the shell 21 is provided with two pipe joints 241 that are connected to the heat exchange channel. The pipe joints 241 are connected to the thermal management joint 60 through a first connecting pipe and / or the pipe joints 241 between the thermal management components 24 are connected through a second connecting pipe.

[0319] The pipe joint 241 and the thermal management joint 60 are both detachably connected via a first connecting pipe and / or the pipe joints 241 between the thermal management components 24 are detachably connected via a second connecting pipe.

[0320] When the heat exchange medium flows through a single battery module 20 to adjust the temperature, the heat exchange medium flows into the heat exchange channel from one of the two pipe joints 241 , and flows out from the other of the two pipe joints 241 after flowing through the heat exchange channel.

[0321] It should be noted that the pipe joint 241 and the thermal management joint 60 are both detachably connected through a first connecting pipe, thereby realizing a detachable connection between the thermal management component 24 and the thermal management joint 60; the pipe joints 241 between the thermal management components 24 are detachably connected through a second connecting pipe, thereby realizing a detachable connection between the thermal management components 24. When at least some of the thermal management components 24 are connected in series, one end of the second connecting pipe is connected to the pipe joint 241 of one of the two adjacent thermal management components 24 (for example, the pipe joint 241 serves as a liquid inlet joint) and the other end of the second connecting pipe is connected to the pipe joint 241 of the other of the two adjacent thermal management components 24 (for example, the pipe joint 241 serves as a liquid outlet joint).

[0322] The detachable connection between the first connecting pipe and the pipe joint 241 , the detachable connection between the first connecting pipe and the thermal management joint 60 , and the detachable connection between the second connecting pipe and the pipe joint 241 may all be plug connections.

[0323] In the above technical solution, two pipe joints 241 connected to the heat exchange channel of the thermal management component 24 are arranged on the outer wall of the shell 21, which facilitates the connection and separation between the thermal management component 24 and the thermal management joint 60, or facilitates the connection or separation between the thermal management components 24.

[0324] In the above technical solution, by setting a pipe joint 241 on the outer wall of the shell 21 that is connected to the heat exchange channel of the thermal management component 24, the connection and separation between the thermal management component 24 and the thermal management joint 60 are facilitated, or the connection or separation between the thermal management components 24 is facilitated.

[0325] In some embodiments, referring to FIG. 5-FIG . 7 , the two pipe joints 241 of the same battery module 20 are located on the same side of the battery module 20 .

[0326] The two pipe joints 241 of the same battery module 20 being located on the same side of the battery module 20 means that the two pipe joints 241 of the same battery module 20 are located on the same side in the horizontal direction of the battery module 20. For example, the two pipe joints 241 of the same battery module 20 may be located on one side of the battery module 20 in the longitudinal direction.

[0327] In the above technical solution, the pipe joints 241 of the same battery module 20 are arranged on the same side, which facilitates the connection or separation between the thermal management component 24 of the battery module 20 and the thermal management components 24 or thermal management joints 60 of other battery modules 20.

[0328] In some embodiments, referring to FIG. 1-FIG . 4 , a plurality of battery modules 20 are arranged in one or more layers in the vertical direction.

[0329] The plurality of battery modules 20 may be arranged in a layer in the vertical direction, or may be arranged in multiple layers in the vertical direction, with each layer including at least one battery module 20 .

[0330] In the above technical solution, the multiple battery modules 20 are arranged in one or more layers in the vertical direction, which can make the arrangement of the battery modules 20 compact, and is beneficial to improving the energy density of the battery 100.

[0331] In some embodiments, multiple battery modules 20 are arranged in a layer in the vertical direction, and at least two battery modules 20 have different heights in the vertical direction. An avoidance space 31 for avoiding the vehicle beam 70 is defined between the battery modules 20 of different heights.

[0332] At least two battery modules 20 have different heights in the vertical direction. The heights of two battery modules 20 may be different, or the heights of three or more battery modules 20 may be different. The arrangement can be based on the actual needs of the avoidance beam 70.

[0333] In the above technical solution, when multiple battery modules 20 are arranged in a layer in the vertical direction, at least two battery modules 20 have different heights in the vertical direction, and an avoidance space 31 for avoiding the vehicle beam 70 is defined between the battery modules 20 of different heights. Therefore, when the battery 100 is installed on the vehicle beam 70, the space between the beam bodies of the vehicle beam 70 can be fully utilized to avoid the vehicle beam 70, making the structure compact.

[0334] In some embodiments, the battery module 20 includes a shell 21 and battery cells 221. The battery cells 221 are disposed in the shell 21. The battery cells 221 in the shell 21 of a single battery module 20 are arranged in at least one layer in the up and down directions. The battery cells 221 of battery modules 20 with different heights have different numbers of arranged layers in the up and down directions.

[0335] The battery cells 221 in the outer shell 21 of a single battery module 20 are arranged in at least one layer in the up and down directions. For example, the battery cells 221 in the outer shell 21 of a single battery module 20 can be arranged in one layer in the up and down directions. The battery cells 221 in the outer shell 21 of a single battery module 20 can also be arranged in multiple layers in the up and down directions. The height of the battery module 20 is different when the number of layers of the battery cells 221 arranged in the up and down directions is different. Therefore, the height adjustment of the battery module 20 can be facilitated by adjusting the number of layers of the battery cells 221 of the battery module 20 arranged in the up and down directions.

[0336] In the above technical solution, by setting the battery modules 20 of different heights to a structure with different numbers of layers of battery cells 221 arranged in the up and down directions, the battery modules 20 of different heights can adopt battery cells 221 of uniform specifications, and the number of arrangement layers of the battery cells 221 is set to be different, which can facilitate the assembly of battery modules 20 of different heights and reduce costs.

[0337] In some embodiments, the battery module 20 includes a thermal management component 24 disposed in the housing 21 , and the thermal management component 24 is located between two adjacent layers of battery cells 221 .

[0338] In the above technical solution, by arranging a thermal management component 24 in the outer shell 21 of the battery module 20, the temperature of the battery cell 221 can be adjusted, and the thermal management component 24 is located between two adjacent layers of battery cells 221 of the battery module 20, so that the two adjacent layers of battery cells 221 share one thermal management component 24. This not only ensures that the temperature of each layer of battery cells 221 can be adjusted by the thermal management component 24, but also reduces the number of thermal management components 24 of the single battery module 20.

[0339] In some embodiments, referring to FIG. 1-FIG . 4 , the plurality of battery modules 20 are arranged in two or three layers in the vertical direction.

[0340] The plurality of battery modules 20 may be arranged in two layers in the vertical direction, or the plurality of battery modules 20 may be arranged in three layers in the vertical direction.

[0341] In the above technical solution, multiple battery modules 20 are arranged in two or three layers in the vertical direction. While making the arrangement of the battery modules 20 compact and beneficial to improving the energy density of the battery 100, the overall height of the battery 100 will not be too high to affect the use scenario of the battery 100, and the size of the battery 100 in the vertical direction is relatively appropriate. When the battery 100 is installed on the vehicle beam 70, the chassis of the vehicle 1000 can be avoided from being too low due to the excessive size of the battery 100 in the vertical direction.

[0342] In some embodiments, referring to Figures 1-4, multiple battery modules 20 are arranged in multiple layers in the up and down directions, and the battery modules 20 located on the top layer are arranged sequentially along the second direction. An avoidance space 31 for avoiding the vehicle beam 70 is defined between adjacent battery modules 20 located on the top layer in the second direction, and the second direction is perpendicular to the length direction of the vehicle beam 70.

[0343] The uppermost battery module 20 is relative to the multiple battery modules 20 arranged in the vertical direction. The uppermost battery module 20 refers to the battery module 20 at the highest position among the multiple battery modules 20 arranged in the vertical direction.

[0344] In the above technical solution, multiple battery modules 20 are arranged in multiple layers in the vertical direction, which can make the arrangement of the battery modules 20 compact, which is beneficial to improving the energy density of the battery 100; and the battery modules 20 located on the top layer are arranged in sequence along the length direction perpendicular to the vehicle beam 70, so that the avoidance space 31 for avoiding the vehicle beam 70 can be conveniently defined between adjacent battery modules 20.

[0345] In some embodiments, referring to FIG. 1-FIG . 4 , the length direction of the battery module 20 located at the uppermost layer extends along the length direction of the vehicle beam 70 .

[0346] For example, the vehicle beam 70 includes a longitudinal beam 71 extending along the length direction of the vehicle beam 70, and an avoidance space 31 for avoiding the longitudinal beam 71 is defined between the battery modules 20 adjacent in the second direction. The avoidance space 31 is open on both sides along the length direction of the vehicle beam 70 and the upper side of the avoidance space 31 is open. The avoidance space 31 can extend along the length direction of the vehicle beam 70, and at least a portion of the longitudinal beam 71 is accommodated in the avoidance space 31.

[0347] In the above technical solution, the length direction of the battery module 20 located on the top layer is extended along the length direction of the vehicle beam 70, so that an avoidance space 31 extending along the length direction of the vehicle beam 70 can be defined between the adjacent battery modules 20 located on the top layer, which can better avoid the vehicle beam 70 and can make the size of the battery module 20 in the length direction of the vehicle beam 70 larger, so that the space in the length direction of the vehicle beam 70 can be more fully utilized.

[0348] In some embodiments, referring to Figures 2-5, the battery 100 includes: a distribution box 50, the distribution box 50 is arranged on the load-bearing bracket 10, at least some battery modules 20 have a first interface 23, the distribution box 50 has a second interface 51, the first interface 23 and the second interface 51 are connected by a connecting harness, and the first interfaces 23 of the battery modules 20 on the same layer are located on the same side.

[0349] At least some of the battery modules 20 have the first interface 23. Some of the battery modules 20 may have the first interface 23, or each battery module 20 may have the first interface 23. For example, when the battery module 20 includes the first battery module 30 and the second battery module 40 described above, the first battery module 30 has the first interface 23, while the second battery module 40 is not provided with the first interface 23.

[0350] The first interfaces 23 of the battery modules 20 in the same layer are located on the same side, which means that the first interfaces 23 of the battery modules 20 in the same layer are all located on the same side along the horizontal direction. For example, if the first interface 23 of each battery module 20 is located on one side of the battery module 20 along the length direction of the battery module 20, and the length direction of all battery modules 20 in the same layer is consistent, the first interfaces 23 of all battery modules 20 in the same layer are located on the same side along the length direction of the battery module 20.

[0351] In the above technical solution, by setting the interfaces of the battery modules 20 on the same layer on the same side, it is convenient to electrically connect or separate the battery modules 20 on the same layer and the distribution box 50, which can improve the efficiency of the electrical connection and separation operations between the battery modules 20 on the same layer and the distribution box 50.

[0352] In some embodiments, referring to FIG. 2-FIG . 4 , multiple battery modules 20 are arranged in multiple layers in the vertical direction, and at least two layers of battery modules 20 are arranged in different directions and have different length extension directions.

[0353] At least two layers of battery modules 20 are arranged in different directions, and the arrangement directions of two adjacent layers of battery modules 20 may be different. Different arrangement directions means that there is an angle between the arrangement directions, for example, the arrangement directions may be perpendicular to each other.

[0354] At least two layers of battery modules 20 have different length extension directions, and the length extension directions of two adjacent layers of battery modules 20 may be different. Different length extension directions means that there is an angle between the length extension directions, for example, the length extension directions may be perpendicular to each other.

[0355] In the above technical solution, multiple battery modules 20 are arranged in multiple layers in the up and down directions, which can make the arrangement of the battery modules 20 compact, which is beneficial to improving the energy density of the battery 100; and, at least two layers of battery modules 20 are arranged in different directions, and at least two layers of battery modules 20 have different length extension directions, which can make the arrangement of the battery modules 20 more compact and more balanced as a whole, thereby making the structural strength of the entire battery 100 higher and the overall structure more stable and reliable.

[0356] In some embodiments, referring to Figures 2-4, one layer of battery modules 20 in two adjacent layers of battery modules 20 is arranged along a first direction and the length direction of the battery modules 20 extends along a second direction, and the other layer of battery modules 20 in the two adjacent layers of battery modules 20 is arranged along the second direction and the length direction of the battery modules 20 extends along the first direction, and the first direction is perpendicular to the second direction and both are parallel to the horizontal direction.

[0357] The arrangement direction of each layer of battery modules 20 is perpendicular to the length extension direction of the battery modules 20 in that layer, the arrangement directions of two adjacent layers of battery modules 20 are perpendicular, and the length directions of two adjacent layers of battery modules 20 are perpendicular.

[0358] In the above technical solution, by vertically setting the arrangement direction of two adjacent layers of battery modules 20 and the extension direction of two adjacent layers of battery modules 20, the two adjacent layers of battery modules 20 can be cross-arranged, which can further improve the structural strength of the entire battery 100 and make the overall structure more stable and reliable.

[0359] In some embodiments, referring to Figures 2-5, the battery 100 includes: a distribution box 50, which is arranged on a load-bearing bracket 10, and multiple battery modules 20 are arranged in multiple layers in the up and down directions, and the distribution box 50 and the topmost battery module 20 are located on the same layer.

[0360] In the above technical solution, multiple battery modules 20 are arranged in multiple layers in the up and down directions, so that the arrangement of the battery modules 20 can be compact, which is beneficial to improving the energy density of the battery 100; and, by locating the distribution box 50 and the battery module 20 located on the top layer on the same layer, the distribution box 50 will not be blocked by the battery module 20 and affect the electrical connection between the distribution box 50 and other components outside the battery 100, thereby facilitating the electrical connection between the distribution box 50 and other components outside the battery 100.

[0361] In some embodiments, referring to FIG. 2 to FIG. 5 , the distribution box 50 is located in the middle of the arrangement direction of the uppermost battery module 20 .

[0362] The uppermost battery module 20 is relative to the multiple battery modules 20 arranged in the vertical direction. The uppermost battery module 20 refers to the battery module 20 at the highest position among the multiple battery modules 20 arranged in the vertical direction.

[0363] In the above technical solution, by locating the distribution box 50 in the middle of the arrangement direction of the battery module 20, the structural layout of the distribution box 50 on the opposite sides of the arrangement direction of the battery module 20 is balanced, so that the overall structure of the battery 100 is balanced and stable, and when the battery 100 is applied to the vehicle 1000, the influence of vibration impact or load-bearing deformation on the distribution box 50 can be reduced.

[0364] In some embodiments, referring to Figures 2-5, the multiple battery modules 20 include a first battery module 30 and a second battery module 40, there is at least one first battery module 30, and there is one second battery module 40. The second battery module 40 is located on the top layer and in the middle of the arrangement direction of the top battery modules 20, and the distribution box 50 is integrated with the second battery module 40.

[0365] In the above technical solution, by integrating the distribution box 50 with the second battery module 40 located on the top layer, the structure can be made compact, the occupied space can be reduced, and the overall energy density of the battery 100 can be improved; and since the second battery module 40 is located on the top layer and in the middle of the arrangement direction of the top battery module 20, it is possible to set the distribution box 50 on the top layer, so that the distribution box 50 will not be blocked by the battery module 20 and affect the electrical connection between the distribution box 50 and other components outside the battery 100, thereby facilitating the electrical connection between the distribution box 50 and other components outside the battery 100, and at the same time, the distribution box 50 can be located in the middle of the arrangement direction of the top battery module 20, so that the structural layout of the distribution box 50 on the opposite sides in the arrangement direction of the battery module 20 is balanced, so that the overall structure of the battery 100 is balanced and stable, and when the battery 100 is installed on the vehicle beam 70, the influence of vibration impact or load-bearing deformation on the distribution box 50 can be reduced.

[0366] In some embodiments, referring to Figures 2-5, multiple battery modules 20 are arranged in two layers in the upper and lower directions, and the multiple battery modules 20 located in the lower layer are all first battery modules 30, and the battery modules 20 located in the lower layer include first battery modules 30 and second battery modules 40; wherein, the first battery module 30 has a first interface 23, and the distribution box 50 has a second interface 51, and the first interface 23 and the second interface 51 are connected by a connecting harness, and the first interface 23 of the battery modules 20 in the same layer are located on the same side, and the second interface 51 and the first interface 23 of the first battery module 30 located in the upper layer are located on the same side.

[0367] When the plurality of battery modules 20 are arranged in two layers in the vertical direction, the one with a higher height position is the upper layer, and the one with a lower height position is the lower layer.

[0368] The second interface 51 is located on the same side as the first interface 23 of the first battery module 30 located above. This means that the second interface 51 and the first interface 23 of the first battery module 30 located above are located on the same horizontal side. For example, the second interface 51 is located on one side of the second battery module 40 along the length of the second battery module 40, the first interface 23 of the first battery module 30 located above is located on one side of the length of the first battery module 30, the lengths of the first battery module 30 and the second battery module 40 located above are aligned, and the first interface 23 of the first battery module 30 located above is located on the same side of the length as the second interface 51 of the second battery module 40.

At the same time, the overall height of the battery 100 will not be too high to affect the use scenario of the battery 100, so that the size of the battery 100 in the vertical direction is more appropriate. When the battery 100 is installed on the vehicle beam 70, it can avoid the chassis of the vehicle 1000 being too low due to the excessive size of the battery 100 in the vertical direction. In addition, the interface is provided in the first battery module 30 and the distribution box 50, thereby In one step, the connection and separation between the battery module 20 and the distribution box 50 are made more convenient. At the same time, by setting the interfaces of the battery modules 20 on the same layer on the same side, it is convenient to electrically connect or separate the battery modules 20 on the same layer and the distribution box 50, which can improve the efficiency of the electrical connection and separation operations between the battery modules 20 on the same layer and the distribution box 50; in addition, the second interface 51 of the distribution box 50 and the first interface 23 of the first battery module 30 on the upper layer are located on the same side, which facilitates the electrical connection between the first battery module 30 on the same layer and the distribution box 50, and can reduce the length of the connection harness.

For example, if the battery modules 20 in the same layer have the same longitudinal direction, the two pipe joints 241 of the battery modules 20 in the same layer are all located on the same side in the longitudinal direction of the battery modules 20.

[0373] In the above technical solution, by setting up a thermal management system including multiple thermal management components 24, the temperature of each battery module 20 can be adjusted, so that the battery module 20 has a separate thermal management component 24, which can improve the temperature adjustment efficiency of the thermal management component 24 on the battery cells 221 of the battery module 20, and also facilitate the maintenance of the battery module 20; in addition, by locating the pipe joints 241 of the battery modules 20 located on the same layer on the same side, the connection and separation between the thermal management components 24 of the battery modules 20 on the same layer and between the thermal management components 24 of the battery modules 20 and the thermal management joints 60 are facilitated, thereby reducing the length of the connecting pipes between the thermal management components 24 of the battery modules 20 on the same layer.
