Description

Technical Field

[0001] This application relates to the field of batteries, and more particularly to a battery and a vehicle. Background Technology

[0002] In batteries, the battery management unit is typically arranged horizontally within the casing. This arrangement occupies internal space, resulting in a longer overall battery pack length, which is detrimental to lightweight design. To address this, arranging the battery management unit vertically (along a vertical direction) can significantly reduce the overall pack length and improve space utilization. However, this vertical arrangement means that the mounting bolts for the battery management unit cannot be assembled using conventional tools due to space constraints, leading to lower assembly efficiency. Utility Model Content

[0003] The purpose of this application is to provide a battery and a vehicle.

[0004] According to a first aspect of the embodiments of this application, a battery is provided, the battery comprising:

[0005] A housing, the housing including a mounting space, the mounting space including a mounting port;

[0006] A battery management unit is disposed in the mounting space along the height direction of the housing;

[0007] The bracket includes a receiving unit and a fixing unit. The battery management unit is disposed in the receiving unit, and the fixing unit is connected to the housing, with the mounting end of the fixing unit facing the mounting port.

[0008] It should be noted that the mounting end here refers to the operating end of the fixing device, such as the tightening end of a nut or the pressing end of a clip. The mounting end faces the mounting opening, meaning that the installer can operate the fixing unit through this mounting opening. Furthermore, the direction of the mounting opening is not limited; it can be located on the top surface or the side wall, as long as the mounting end faces the mounting opening, it falls within the protection scope of this application.

[0009] Based on the above setup, the battery management unit can be first fixed to the housing unit of the bracket, and then the battery management unit and the bracket can be fixed together to the housing through the mounting port. This setup, on the one hand, allows the battery management unit to be arranged vertically, reducing the overall length of the pack and improving space utilization. On the other hand, since the mounting end faces the mounting port, it is convenient for the installer to install it through the port. In other words, it improves space utilization while also facilitating installation.

[0010] In one embodiment, the housing unit includes a housing space disposed along the height direction, and the battery management unit is detachably connected to the housing space.

[0011] Based on the above configuration, the housing space is arranged along the height direction, which facilitates the cooperation and fixation of the battery management unit. Furthermore, since the battery management unit is detachably connected to the housing space, it can be easily fixed and disassembled. In addition, with the battery management unit installed within the housing space, the side walls of the housing unit can protect the battery management unit. In the event of an impact, the housing unit can mitigate the impact on the battery management unit.

[0012] In one embodiment, the receiving unit includes a first fixed surface and a first opening, the battery management unit is fixed to the first fixed surface, the first opening is connected to the receiving space, and the first opening is opposite to the first fixed surface.

[0013] With this configuration, the battery management unit can enter the receiving unit through the first opening and fit against the first fixing surface, thus securing the battery management unit and the first fixing surface together. This method of inserting the battery management unit through the first opening is simple and quick, improving assembly efficiency.

[0014] In one embodiment, the receiving unit includes a second fixing surface and a second opening. The fixing unit includes a first sub-unit disposed on the second fixing surface. The second fixing surface is disposed facing the receiving space. The second opening is connected to the receiving space and is disposed opposite to the second fixing surface, and the second opening is disposed facing the mounting port.

[0015] Based on the above settings, when the bracket is fixed to the housing, the first sub-unit can be fixed through the second opening, which is a simple and convenient process.

[0016] Furthermore, the first and second openings can be integrated to form a larger opening space. This makes it easier for the battery management unit to cooperate with the housing unit through this larger opening space, and also facilitates the fixation of the bracket and housing through this larger opening space.

[0017] In one embodiment, the fixing unit includes a second sub-unit, which is connected to the receiving unit and located outside the receiving space, and the second sub-unit is fixedly disposed with the housing.

[0018] Based on the above configuration, the second subunit provides external fixation, and the first subunit provides internal fixation, which enables multi-point fixation, thereby making the bracket and the shell more secure and achieving better stability.

[0019] In one embodiment, the battery includes a cell disposed in the mounting space, the receiving unit and the cell are spaced apart to form a bending space, and the second sub-unit is disposed within the bending space.

[0020] The wiring harness needs to be bent to connect to other parts, so the bending space here can meet the bending radius requirements of the wiring harness to ensure its smooth operation. Furthermore, placing the second sub-unit in this bending space allows both units to share a single space, further increasing the battery's space utilization.

[0021] In one embodiment, the second subunit is configured as a triangular prism, and the triangular prism includes an adjacent first sidewall and a second sidewall, the first sidewall being fixedly disposed with the receiving unit, and the second sidewall being fitted with the housing;

[0022] The second subunit includes a connecting unit disposed on the second sidewall and used to fix the second subunit and the housing.

[0023] Based on the above design, this section is firstly designed as a triangular prism with a triangular structure at the fixing point. Furthermore, one of the two adjacent sidewalls is fixed to the housing unit, and the other is fixed to the shell. This makes the second sub-unit structurally more stable and less prone to shaking after the support is fixed.

[0024] In one embodiment, the triangular prism includes a third sidewall disposed adjacent to the first sidewall and the second sidewall, the third sidewall being open and the opening facing the mounting opening.

[0025] The opening is oriented towards the mounting port, allowing the connection unit of the second sub-unit to be fixed during installation by entering through the mounting port. This fixing process is simple and convenient, and can improve assembly efficiency.

[0026] In one embodiment, there are multiple supports, which are arranged along the length of the supports, and adjacent supports share a sidewall.

[0027] Based on the above configuration, the multiple supports are integrated into one piece, which facilitates processing and allows them to share a single sidewall. This is equivalent to having reinforcing ribs between the supports, which increases the overall strength of the supports.

[0028] In one embodiment, a positioning post is provided on the housing, the positioning post is arranged along the height direction, and the fixing unit includes a fixing hole;

[0029] When the bracket is fitted into the housing, the positioning post is located inside the fixing hole.

[0030] Based on the above configuration, the positioning post can help position the bracket simply by inserting it into the fixing hole. Furthermore, the positioning post can be used to fix the bracket to the housing.

[0031] According to a second aspect of the embodiments of this application, a vehicle is provided, including a battery as described in any of the above embodiments.

[0032] The beneficial technical effects of the technical solutions provided in this application are:

[0033] The system comprises a housing, a battery management unit, and a bracket. The housing includes an installation space with an installation opening. The battery management unit is disposed within the installation space along the height of the housing. The bracket includes a receiving unit and a fixing unit. The battery management unit is disposed within the receiving unit. The fixing unit is connected to the housing, and its mounting end faces the installation opening.

[0034] Based on the above setup, the battery management unit can be first fixed to the housing unit of the bracket, and then the battery management unit and the bracket can be fixed together to the housing through the mounting port. This setup, on the one hand, allows the battery management unit to be arranged vertically, reducing the overall length of the pack and improving space utilization. On the other hand, since the mounting end faces the mounting port, it is convenient for the installer to install it through the port. In other words, it improves space utilization while also facilitating installation. Attached Figure Description

[0071] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0072] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0073] New energy vehicles consist of components such as a battery (10), an electric motor, a thermal management system, a body and chassis system, and auxiliary systems. The battery (10) serves as the energy source, providing the electrical energy required for vehicle propulsion and ensuring safe and efficient operation. The electric motor converts the electrical energy from the battery (10) into mechanical energy, thereby driving the vehicle forward. Electric vehicles can use different types of electric motors, such as permanent magnet synchronous motors or AC induction motors. The thermal management system ensures that the battery (10), electric motor, and power electronic components are maintained within their optimal operating temperature range, improving efficiency and extending service life. The body and chassis system, including suspension, steering, and braking, provides structural support and driving stability. Auxiliary systems, such as air conditioning, infotainment, and lighting systems, enhance driving comfort and convenience.

[0074] These components work closely together to form a complex system to maintain the stable operation of the vehicle.

[0075] Among the aforementioned components, the battery 10 is an important part of new energy vehicles, mainly consisting of a housing 100, a cell 400, a connector, a battery management system 200 (BMS), a heat dissipation system, a fuse device and a relay, as well as voltage and temperature sensors.

[0076] The housing 100 is used to install and protect the individual battery 10 components. The cells 400 are the basic energy storage units of the battery 10; they are combined in series or parallel to form the required voltage and capacity. Connectors ensure efficient electrical connections between cells 400 and between cells 400 and other electrical components. The battery management unit 200, acting as the "brain" of the battery 10 group, receives data from voltage and temperature sensors, controls the equalization circuit to balance the charging state of each cell 400, and manages the operation of the cooling system to ensure the safe, stable, and efficient operation of the battery 10 group. Furthermore, the battery management unit 200 is responsible for communicating with other vehicle systems, such as displaying the remaining battery charge and controlling the charging process. The cooling system regulates the operating temperature of the battery 10 group based on data provided by the voltage and temperature sensors, ensuring that the battery 10 operates within a safe range. Fuse devices and relays open or close circuits as needed to protect the battery 10 from potential electrical faults. The voltage and temperature sensors monitor the operating status of the battery 10 group in real time and feed the information back to the BMS.

[0077] Based on the above description, it is clear that the battery management unit 200 is indispensable in the battery 10. However, in the battery 10, the battery management unit 200 is usually arranged horizontally within the housing 100. This arrangement occupies internal space in the battery pack, resulting in a longer overall length of the battery pack, which is not conducive to lightweight design. Therefore, arranging the battery management unit 200 vertically (along the vertical direction) can significantly reduce the overall pack length and improve space utilization. However, vertical arrangement would prevent the mounting bolts of the battery management unit 200 from being assembled using conventional tools due to space constraints, resulting in lower assembly efficiency.

[0078] refer to Figures 1-9 As shown, this application proposes a battery 10, which includes a housing 100, a battery management unit 200, and a support 300. (Reference) Figure 1 and Figure 2 As shown, the housing 100 includes a mounting space 110, which includes a mounting opening 111. The battery management unit 200 is disposed in the mounting space 110 along the height direction Z of the housing 100. That is, the battery management unit 200 is arranged longitudinally.

[0079] The bracket 300 includes a receiving unit 310 and a fixing unit 320. The battery management unit 200 is disposed in the receiving unit 310, and the fixing unit 320 is connected to the housing 100, with the mounting end of the fixing unit 320 facing the mounting port 111. It should be noted that the mounting end here is the operating end of the fixing device, such as the tightening end of a nut or the pressing end of a clip. The fact that the mounting end faces the mounting port 111 means that the installer can operate the fixing unit 320 through the mounting port 111. Furthermore, the direction of the mounting port 111 is not limited; it can be located on the top surface or on the side wall, as long as the mounting end faces the mounting port 111, it is within the scope of protection of this application.

[0080] Based on the above configuration, the battery management unit 200 can be first fixed to the receiving unit 310 of the bracket 300, and then the battery management unit 200 and the bracket 300 can be fixed together to the housing 100 through the mounting port 111. This configuration, on the one hand, allows the battery management unit 200 to be arranged longitudinally, reducing the overall length of the package and improving space utilization. On the other hand, since the mounting end faces the mounting port 111, it facilitates installation by the installer through the mounting port 111. In other words, it improves space utilization while also facilitating installation.

[0081] In one embodiment, reference Figure 4 , Figure 5 , Figure 6 as well as Figure 8 and Figure 9 As shown, the housing unit 310 includes a housing space 311, which is arranged along the height direction Z, and the battery management unit 200 is detachably connected to the housing space 311.

[0082] Based on the above configuration, the receiving space 311 is positioned along the height direction Z, which facilitates the cooperation and fixation of the battery management unit 200 with it. Furthermore, since the battery management unit 200 is detachably connected to the receiving space 311, it can be easily fixed and disassembled. In addition, with the battery management unit 200 installed within the receiving space 311, the sidewalls of the receiving unit 310 can protect the battery management unit 200. When subjected to impact, the receiving unit 310 can mitigate the impact on the battery management unit 200.

[0083] In one embodiment, reference Figure 4 , Figure 5 , Figure 6 as well as Figure 8 and Figure 9 As shown, the housing unit 310 includes a first fixing surface 312 and a first opening 314. The battery management unit 200 is fixed to the first fixing surface 312. The first opening 314 is connected to the housing space 311 and is disposed opposite to the first fixing surface 312.

[0084] With this configuration, the battery management unit 200 can enter the receiving unit 310 through the first opening 314 and fit against the first fixing surface 312, thus securing the battery management unit 200 and the first fixing surface 312 together through the first opening 314. This method of inserting the battery management unit 200 through the first opening 314 is simple and quick, improving assembly efficiency.

[0085] In one embodiment, reference continues Figure 4 , Figure 5 , Figure 6 as well as Figure 8 and Figure 9 As shown, the receiving unit 310 includes a second fixing surface 313 and a second opening 315. The fixing unit 320 includes a first sub-unit 321, which is disposed on the second fixing surface 313. The second fixing surface 313 faces the receiving space 311. The second opening 315 is connected to the receiving space 311 and is opposite to the second fixing surface 313, with the second opening facing the mounting port 111. It should be noted that the first sub-unit 321 here can be a bolt, nut, or a clip, etc., as long as it can be used for fixing, it is within the scope of protection of this application.

[0086] Based on the above settings, when the bracket 300 is fixed to the housing 100, the first subunit 321 can be fixed through the second opening 315, which is a simple and convenient process.

[0087] In addition, refer to Figure 8 As shown, the first opening 314 and the second opening 315 can be integrated to form a larger opening space. This makes it easier for the battery management unit 200 to cooperate with the housing unit 310 through this larger opening space, and also facilitates the fixation of the bracket 300 and the housing 100 through this larger opening space.

[0088] In one embodiment, reference Figure 6 and Figure 9 As shown, the fixing unit 320 includes a second sub-unit 322, which is connected to the receiving unit 310 and located outside the receiving space 311. The second sub-unit 322 is fixedly disposed to the housing 100. That is, the second sub-unit 322 is disposed outside the receiving space 311.

[0089] Based on the above configuration, the second subunit 322 provides external fixation and the first subunit 321 provides internal fixation, which can achieve multi-point fixation, thereby fixing the bracket 300 and the housing 100 more firmly and achieving better stability.

[0090] In one embodiment, reference Figure 1 and Figure 3 As shown, the battery 10 includes a cell 400, which is disposed in the mounting space 110. The housing unit 310 and the cell 400 are spaced apart to form a bending space 120. The second sub-unit 322 is disposed within the bending space 120.

[0091] refer to Figure 3 and Figure 4 As shown, the wiring harness needs to be bent to a certain extent to connect to other parts. Therefore, the bending space 120 here can meet the bending radius requirements of the wiring harness to ensure its smooth operation. In addition, placing the second sub-unit 322 in this bending space 120 can achieve the effect of both sharing a space, thereby further increasing the space utilization of the battery 10.

[0092] In one embodiment, reference Figure 6 and Figure 9 As shown, the second subunit 322 is configured as a triangular pillar, and the triangular pillar includes an adjacent first sidewall 322A and a second sidewall 322B. The first sidewall 322A is fixedly disposed with the receiving unit 310, and the second sidewall 322B is fitted to the housing 100. The second subunit 322 includes a connecting unit 324, which is disposed on the second sidewall 322B and used to fix the second subunit 322 and the housing 100. That is, the connecting unit 324 fixes the second sidewall 322B to the housing 100.

[0093] Based on the above design, this part is firstly designed as a triangular prism, with a triangular structure at the fixing point. Furthermore, one of the two adjacent sidewalls is fixed to the receiving unit 310, and the other is fixed to the housing 100. This makes the second sub-unit 322 more structurally stable and less prone to shaking after the bracket 300 is fixed.

[0094] In one embodiment, reference continues Figure 6 and Figure 9 As shown, the triangular prism includes a third sidewall 322C that is adjacent to the first sidewall 322A and the second sidewall 322B. The third sidewall 322C is open and the opening faces the mounting port 111.

[0095] The opening is oriented toward the mounting port 111, allowing the connection unit 324 of the second subunit 322 to be fixed during installation. This fixing process is simple and convenient, and can improve assembly efficiency.

[0096] refer to Figure 4As shown, there are multiple brackets 300, arranged along the length direction X of the bracket 300, with adjacent brackets 300 sharing a sidewall. The illustration shows only two brackets 300, but the actual number can be determined based on the specific battery pack. For example, the number of brackets 300 can be 2, 3, 4, etc.

[0097] Based on the above configuration, the multiple supports 300 are integrated into one piece, which facilitates processing and allows them to share a common sidewall. This is equivalent to having reinforcing ribs between the multiple supports 300, which increases the overall strength of the multiple supports 300.

[0098] In one embodiment, reference Figure 7 and Figure 8 As shown, a positioning post 130 is provided on the housing 100. The positioning post 130 is arranged along the height direction Z. The fixing unit 320 includes a fixing hole 323. When the bracket 300 is engaged with the housing 100, the positioning post 130 is located in the fixing hole 323.

[0099] Based on the above configuration, the positioning post 130 can help position the bracket 300 simply by inserting it into the fixing hole 323. Furthermore, the positioning post 130 can be used to fix the bracket 300 and the housing 100.

[0100] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
