[0041] As a crucial core component, the battery pack for new energy vehicles faces increasingly stringent requirements regarding performance, energy density, and safety. A typical battery pack for a new energy vehicle includes a battery casing, cell modules, and electrical components such as a battery management system (BMS). Both the cell modules and electrical components are housed within the battery casing. These electrical components include the BMS and various battery circuit breaker units (BDUs), and are generally arranged around the cell modules within the battery casing.

[0042] However, the electrical components in the current battery assembly occupy a large amount of space and require reserved assembly space, resulting in low space utilization within the battery casing.

[0043] To address the aforementioned issues, this application provides a battery assembly and vehicle. By designing the layout of electrical components within the housing, the battery management module and the circuit breaker module are arranged in different areas of the same chamber, effectively separating them while fully utilizing the space on one side of the housing. Furthermore, the battery management module and the circuit breaker module are fixed using mounting beams, improving the installation reliability of the electrical components. No pre-reserved assembly space is required, thereby reducing the overall volume of the battery assembly.

[0044] The technical solution of this application will be described in detail below through specific embodiments.

[0045] Figure 1 for.

[0046] like Figures 1 to 4As shown, this application embodiment provides a battery assembly 10, which includes a housing 100, a cell assembly 200, and an electrical assembly 300. The housing 100 has a receiving cavity 101, which includes a first chamber 101a and a second chamber 101b. The cell assembly 200 is disposed in the first chamber 101a, and the electrical assembly 300 is disposed in the second chamber 101b, thereby placing the cell assembly 200 and the electrical assembly 300 in two different spaces to ensure the safety of the battery assembly 10.

[0047] The battery cell assembly 200 is used to store electrical energy. The electrical component 300 is used to control the charging and discharging of the battery cell assembly 200, and the electrical component 300 can control and manage the operating status of the electrical component 300, such as temperature and voltage.

[0048] In some embodiments, the electrical component 300 includes a battery management module 310 and a circuit breaker module 320, which are spaced apart within a second chamber 101b. The second chamber 101b contains a plurality of mounting beams 102, which are arranged in parallel and spaced apart. The battery management module 310 and the circuit breaker module 320 are respectively connected to different mounting beams 102.

[0049] It is understood that the function of the battery management module 310 is the same as or similar to that of the BMS, and the function of the circuit breaker module 320 is the same as or similar to that of the BDU. The battery management module 310 manages the operating state of the cell assembly 200, including but not limited to charging / discharging, voltage values, temperature, and charge level. The circuit breaker module 320 acts as a switch during the charging and discharging operations of the cell assembly 200. The components included in the circuit breaker module 320 may include, but are not limited to, relays and fuses. The circuit breaker module 320 ensures the safety of the battery assembly 10.

[0050] It should be noted that in the battery assembly 10 provided in this application embodiment, by designing the layout of the electrical components 300 within the housing 100, the battery management module 310 and the circuit breaker module 320 are arranged in different areas of the same chamber, which separates them from each other while making full use of the space on one side of the housing 100. Furthermore, the battery management module 310 and the circuit breaker module 320 are fixed by the mounting beam 102, which improves the installation reliability of the electrical components 300, eliminates the need to reserve assembly space, and thus reduces the overall volume of the battery assembly 10.

[0051] In one possible implementation, the first chamber 101a and the second chamber 101b are arranged along the length of the housing 100. The battery management module 310 and the circuit breaker module 320 are arranged in the second chamber 101b along the width of the housing 100.

[0052] Define the length direction of the housing 100 as the X direction and the width direction of the housing 100 as the Y direction. The first chamber 101a and the second chamber 101b are arranged along the X direction, and the battery management module 310 and the disconnection module 320 are arranged along the Y direction in the second chamber 101b.

[0053] It can be understood that the electrical component 300 and the battery cell component 200 are arranged in two mutually isolated spaces, which can prevent the battery cell component 200 from affecting the working performance of the electrical component 300. The battery management module 310 and the disconnection module 320 are arranged at intervals in the second chamber 101b, which can prevent electromagnetic interference between the two.

[0054] In some embodiments, the housing 100 may include a frame 110, an upper cover 120 and a bottom guard plate 130. The upper cover 120 and the bottom guard plate 130 are respectively connected to the upper and lower sides of the frame 110, and jointly enclose to form a receiving cavity 101.

[0055] Among them, the frame 110 includes a border 111 and a partition beam 112. The two ends of the partition beam 112 are respectively connected to the opposite sides of the border 111. The partition beam 112 is configured to divide the receiving cavity 101 into a first chamber 101a and a second chamber 101b. The mounting beam 102 extends along the length direction of the housing 100, and the two ends of the mounting beam 102 are respectively connected to the partition beam 112 and the border 111.

[0056] It can be understood that the upper cover 120 and the upper surface of the frame 110 are connected by fasteners such as bolts, and the contour shape of the upper cover 120 can match the contour shape of the frame 110. The bottom guard plate 130 and the lower surface of the frame 110 are connected by fasteners such as bolts, and the contour shape of the bottom guard plate 130 can match the contour shape of the frame 110.

[0057] The two ends of the partition beam 112 can be connected to the inner edges of the two sides of the frame 110 by fasteners such as bolts, or the two ends of the partition beam 112 can be welded to the inner edges of the two sides of the frame 110 respectively. The specific connection manner of the partition beam 112 and the frame 110 in the embodiments of the present application is not limited.

[0058] Exemplarily, the frame 110 can be fixedly connected by splicing profiles, and the frame 110 can be a square or approximately square structure. The profile section of the frame 110 can be a "mouth" shape, a "day" shape, etc., and the embodiments of the present application do not make specific limitations on this. <P

[0059] It should be noted that the materials of the frame 110, the upper cover 120 and the bottom guard plate 130 can be metals or alloys such as iron and aluminum, and the embodiments of the present application do not make specific limitations on this.

[0060] In some embodiments, the frame 110 may further include a longitudinal beam 113 and a transverse beam 114. The longitudinal beam 113 is located within the first chamber 101a and extends along the length direction of the housing 100. The transverse beam 114 is located within the first chamber 101a and extends along the width direction of the housing 100. The longitudinal beam 113 and the transverse beam 114 together divide the first chamber 101a into a plurality of receiving areas, each receiving area being provided with at least one battery cell module 210.

[0061] The following is a detailed description of the specific structure of the circuit breaker module 320 and the specific assembly method of the circuit breaker module 320 on the mounting beam 102.

[0062] In one possible implementation, the circuit breaker module 320 may include a first circuit breaker unit 321, a second circuit breaker unit 322, a mounting bracket 323, and a mounting plate 324. The mounting bracket 323 is connected to the mounting beam 102, the mounting plate 324 is connected above the mounting bracket 323, the first circuit breaker unit 321 is connected to the mounting plate 324, and the second circuit breaker unit 322 is connected to the mounting bracket 323.

[0063] It is understandable that the mounting plate 324, mounting bracket 323 and mounting beam 102 are fixedly connected at the same time. The mounting plate 324 and mounting bracket 323 form a double-layer mounting structure with the mounting beam 102 as support. The first circuit breaker unit 321 and the second circuit breaker unit 322 are fixed to the mounting plate 324 and the mounting bracket 323 respectively, so that the space in the height direction in the second chamber 101b can be fully utilized and the space utilization rate can be improved.

[0064] In some embodiments, the first circuit breaker unit 321 is located on the side of the mounting plate 324 opposite to the mounting bracket 323. The second circuit breaker unit 322 is located on the side of the mounting plate 324 opposite to the first circuit breaker unit 321.

[0065] The first circuit breaker unit 321 is located on the upper side of the mounting plate 324 and is fixed and supported by the mounting plate 324. The second circuit breaker unit 322 is located on the lower side of the mounting plate 324 and is fixed and supported by the mounting bracket 323. The mounting plate 324 can separate the first circuit breaker unit 321 and the second circuit breaker unit 322, thereby avoiding electromagnetic interference between the first circuit breaker unit 321 and the second circuit breaker unit 322.

[0066] It should be noted that the functions of the first circuit breaker unit 321 and the second circuit breaker unit 322, as well as the specific types of components included therein, can be set according to the specific circuit design of the battery assembly 10. This application embodiment does not make specific limitations in this regard.

[0067] In some embodiments, there may be two mounting brackets 323, which are respectively connected to two mounting beams 102, and the two ends of the second circuit breaker unit 322 are respectively connected to the two mounting brackets 323. The mounting plate 324 spans between the two mounting beams 102, and the two ends of the mounting plate 324 are respectively connected to the two mounting brackets 323.

[0068] The mounting bracket 323 is correspondingly provided with the mounting beam 102, and at least one mounting bracket 323 can be installed on the mounting beam 102, which provides support for the circuit breaker module 320. The mounting plate 324 is a flat plate structure and can be horizontally set above the mounting beam 102.

[0069] For example, the circuit breaker module 320 can be supported by two spaced-apart mounting beams 102. The two mounting beams 102 are located at opposite ends of the bottom side of the circuit breaker module 320.

[0070] In some embodiments, the mounting bracket 323 may include a bracket body 3231 and a connecting portion 3232. The bracket body 3231 covers the outside of the mounting beam 102, and the connecting portion 3232 is connected to the outside of the bracket body 3231. The position of the connecting portion 3232 is lower than the top surface of the mounting beam 102, and the second circuit breaker unit 322 is connected to the connecting portion 3232.

[0071] Understandably, the mounting bracket 323 can be a sheet metal structure. The main body of the bracket 3231 is erected on the mounting beam 102, while the connecting part 3232 is positioned lower than the top surface of the mounting beam 102 and lower than the top of the main body of the bracket 3231, thus forming a stepped structure between the main body of the bracket 3231 and the connecting part 3232. This allows for a certain height difference between the mounting plate 324, which connects to the top of the main body of the bracket 3231, and the connecting part 3232, creating a certain installation space between the bottom wall of the mounting plate 324 and the connecting part 3232, allowing for the installation of the second circuit breaker unit 322.

[0072] In addition, the bracket body 3231 is covered above the mounting beam 102. When the second circuit breaker unit 322 is installed, the bracket body 3231 can play a role in limiting and positioning. The connecting part 3232 extends into the inner space between the two mounting beams 102, so that the second circuit breaker unit 322 can be installed.

[0073] For example, the bracket body 3231 may include a first extension section, a second extension section, and a third extension section, wherein the first extension section is connected to the second extension section, the second extension section is connected to the third extension section, the first extension section and the third extension section are located on both sides of the mounting beam 102, and the second extension section is located on the top of the mounting beam 102. The cross-sectional shape of the bracket body 3231 is an inverted "U" shape.

[0074] For example, the bracket body 3231 and the connecting part 3232 can be an integrally formed structure.

[0075] It should be noted that the second circuit breaker unit 322 and the connecting part 3232 can be installed and fixed with bolts or other fasteners. The first circuit breaker unit 321 and the mounting plate 324 can be installed and fixed with bolts or other fasteners. The mounting plate 324 and the bracket body 3231 and the mounting beam 102 can be installed and fixed with bolts or other fasteners.

[0076] In some embodiments, the battery management module 310 may include a housing 311 and a circuit board, the circuit board being disposed within the housing 311, the housing 311 having a protrusion 3111, the protrusion 3111 being connected to the top surface of the mounting beam 102 by fasteners.

[0077] Understandably, the circuit board may include a main control board, which executes battery management control strategies and interacts with the vehicle controller. The circuit board may also include a slave control board, which is electrically connected to the main control board and receives and processes detection information transmitted from the battery cell assembly 200.

[0078] For example, there can be multiple protrusions 3111, which can be respectively disposed at different positions around the housing 311. The protrusions 3111 can be connected to the top of the mounting beam 102 by fasteners such as bolts.

[0079] In one possible implementation, the battery assembly 10 may further include a thermal management module 400, which includes a cold plate 410 and a heating film 420. The cold plate 410 is disposed on the bottom side of the receiving cavity 101. The heating film 420 is bonded to the surface of the cold plate 410 facing the cell assembly 200. The bottom side of the cell assembly 200 is bonded to the heating film 420.

[0080] Understandably, the heating film 420 is bonded between the cold plate 410 and the battery cell assembly 200, with its upper and lower surfaces bonded to the cold plate 410 and the battery cell assembly 200, respectively. When the battery cell assembly 200 needs cooling, the cold plate 410 can absorb the heat transferred from the battery cell assembly 200 through heat conduction; in this case, the heating film 420 does not operate. When the battery cell assembly 200 needs heating, the heating film 420 generates heat through electrical heating and transfers the heat to the battery cell assembly 200 to raise its operating temperature; in this case, the cold plate 410 does not operate.

[0081] For example, the cold plate 410 can be cooled by refrigerant, that is, refrigerant is introduced into the cold plate 410, and the temperature is reduced by the phase change of the refrigerant, and the heat of the battery cell assembly 200 is absorbed.

[0082] For example, the heating film 420 can be a sheet structure, and a resistance wire is provided in the sheet heating film 420. When current is passed through the resistance wire, heat can be generated and the heat can be conducted to the battery cell assembly 200.

[0083] For example, the heating film 420 and the cold plate 410 can be bonded together with thermally conductive adhesive, which can improve the heat transfer efficiency and reduce heat loss.

[0084] This application also provides a vehicle that may include the battery assembly 10 described above. The vehicle provided in this application can be a new energy vehicle, including but not limited to pure electric vehicles, hybrid electric vehicles (plug-in, non-plug-in, etc.), hydrogen fuel cell vehicles, etc., and this application does not specifically limit its scope.

[0085] It is understood that the vehicle provided in this application embodiment also includes an electric drive system, and the battery assembly 10 can supply power to the electric drive system so that the electric drive system can drive the vehicle.

[0086] The vehicle provided in this application embodiment has all the technical solutions and all the technical effects of the aforementioned battery assembly 10, which will not be repeated here.

[0087] This application provides a battery assembly 10 and a vehicle. The battery assembly 10 includes a housing 100, a cell assembly 200, and an electrical assembly 300. The housing 100 has a receiving cavity 101, which includes a first chamber 101a and a second chamber 101b. The cell assembly 200 is disposed in the first chamber 101a, and the electrical assembly 300 is disposed in the second chamber 101b. The electrical assembly 300 includes a battery management module 310 and a circuit breaker module 320, which are spaced apart in the second chamber 101b.

The battery management module 310 and the circuit breaker module 320 are respectively connected to different mounting beams 102, so that the battery management module 310 and the circuit breaker module 320 are arranged in different areas of the same chamber, which separates them from each other and makes full use of the space on one side of the housing 100 without reserving assembly space, thereby reducing the overall volume of the battery assembly 10.
