These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0041] The terms “first,” “second,” “third,” and “fourth,” etc. (if present), in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0042] As mentioned in the background section, in related technologies, the cell modules of a CTC battery pack are one of the power sources for a vehicle. A cell module is formed by stacking multiple cells, which are connected in series or parallel. The cell modules are installed within the mounting cavity of the CTC battery pack and secured using crossbeam brackets, screws, and other structures.

[0043] However, the stability of the battery cell module is poor in the above-mentioned fixing methods.

[0044] To address the aforementioned problems in the prior art, this utility model provides a CTC battery pack and a vehicle. The CTC battery pack includes a bottom guard plate, a top cover, a support strip, and a cell module. The bottom guard plate and the top cover are respectively used to connect to a mounting portion on the vehicle body to form a first mounting cavity. The support strip is disposed on either the bottom guard plate or the top cover, and is located within the first mounting cavity. The cell module is disposed within the first mounting cavity and is bonded to the support strip. Thus, the support strip can simultaneously provide auxiliary support for the cell module and enhance the structural strength of the bottom guard plate or the top cover, thereby improving the overall structural stability.

[0045] The following describes exemplary application scenarios of this utility model.

[0046] The CTC battery pack provided by this utility model can be applied to new energy vehicles, such as pure electric vehicles and plug-in hybrid vehicles. Specifically, the CTC battery pack provided by this utility model, by setting support bars, can both assist in supporting the cell modules and enhance the strength of the bottom protection plate or top cover structure, thereby improving the overall structural stability.

[0047] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0048] Reference Figures 1 to 8 As shown in the embodiment of this application, the CTC battery pack includes a bottom protective plate 100, a top cover 200, a support strip 400, and a cell module 500.

[0049] The bottom guard plate 100 and the top cover 200 are respectively used to connect with the mounting portion 310 on the vehicle body 300 to form a first mounting cavity. A support strip 400 is disposed on either the bottom guard plate 100 or the top cover 200, and the support strip 400 is located in the first mounting cavity. The battery cell module 500 is disposed in the first mounting cavity and is bonded to the support strip 400.

[0050] Reference Figure 3 , Figure 4 and Figure 5 As shown, the battery cell module 500 is bonded to the support strip 400. The support strip 400 serves to assist in supporting the battery cell module 500, thereby improving the overall stability of the battery cell module 500. Furthermore, the support strip 400 is mounted on the bottom cover 100 or the top cover 200, which also enhances the structural strength of the bottom cover 100 or the top cover 200, reducing deformation of the bottom cover 100 or the top cover 200 under external forces.

[0051] It is understood that the support strip 400 can be disposed on either the bottom guard plate 100 or the top cover 200. For example, in one embodiment, the support strip 400 is disposed on the bottom guard plate 100, such that the top of the battery module 500 is bonded to the top cover 200, and the bottom of the battery module 500 is bonded to the support strip 400. Thus, the top cover 200 and the support strip 400 together fix the battery module 500 within the first mounting cavity, preventing displacement or loosening of the battery module 500 during vehicle operation. In another embodiment, the support strip 400 is disposed on the top cover 200, such that the top of the battery module 500 is bonded to the support strip 400, and the bottom of the battery module 500 is bonded to the bottom guard plate 100, which also serves to fix the battery module 500.

[0052] For example, the cell module 500 can be bonded to the top cover 200, the cell module 500 to the bottom cover 100, and the cell module 500 to the support strip 400 using structural adhesive.

[0053] Reference Figure 1 , Figure 2 and Figure 3 As shown, the vehicle body 300 has a mounting portion 310, and the bottom guard plate 100 and the top cover 200 are respectively connected to the mounting portion 310 to form a first mounting cavity for mounting the battery cell module 500. The mounting portion 310 is equivalent to the side frame of the battery pack, and the top cover 200 can be used to form the floor of the vehicle body 300. This allows for a more compact connection between the battery pack and the vehicle body 300, improving the integration of the battery pack and the vehicle body 300, thereby increasing the overall space utilization.

[0054] For example, refer to Figure 1 and Figure 6 As shown, the mounting section 310 can be formed by two opposing sill beams 312, a first crossbeam 313, and a second crossbeam 314 on the vehicle body 300.

[0055] In summary, the CTC battery pack provided in this application embodiment, by setting a support bar 400, can serve to both assist in supporting the cell module 500 and enhance the structural strength of the bottom protective plate 100 or the top cover 200, thereby improving the overall structural stability.

[0056] Reference Figure 3 and Figure 4 As shown, in some embodiments, the support bar 400 is disposed on the bottom protective plate 100.

[0057] In the above embodiment, the support strip 400 can serve both as an auxiliary support for the battery cell module 500 and as a reinforcement of the structural strength of the bottom protection plate 100, reducing the possibility of deformation of the bottom protection plate 100. Thus, during vehicle operation, the bottom protection plate 100 of the CTC battery pack can be protected from impacts from stones, branches, etc., preventing damage and improving safety performance.

[0058] To facilitate understanding of the directions, an XY plane coordinate system is established in the accompanying drawings of the specification, wherein the direction of the X-axis is the first direction in the embodiments of this application, and the direction of the Y-axis is the second direction in the embodiments of this application.

[0059] Reference Figure 3 and Figure 4 As shown, in some embodiments, the support bar 400 is arranged along the arrangement direction of the plurality of cells of the cell module 500.

[0060] Among them, the arrangement direction of the multiple cells in the cell module 500 is the first direction.

[0061] In the above embodiments, the cell module 500 can be formed by stacking multiple cells along a first direction, with the cells connected in series or in parallel. The support strip 400 extends along the first direction and is sequentially bonded to each cell, which increases the contact area between the support strip 400 and the cell module 500, thereby improving the stability of the cell module 500 installation.

[0062] Among them, reference Figure 3 and Figure 4 As shown, multiple battery cell modules 500 and multiple support bars 400 can be configured. Multiple battery cell modules 500 are spaced apart within the first mounting cavity along a second direction, which is perpendicular to the second direction. Multiple support bars 400 are bonded to multiple battery cell modules 500 in a one-to-one correspondence.

[0063] Reference Figure 4 and Figure 5 As shown, in some embodiments, a buffer 110 is provided on the bottom protective plate 100, the buffer 110 abuts against the battery cell module 500, and the edge of the buffer 110 abuts against the edge of the support strip 400.

[0064] In the above embodiment, by providing a buffer 110 between the bottom protective plate 100 and the battery cell module 500, the buffer 110 can absorb and reduce external vibrations and impacts, thereby protecting the battery cell module 500.

[0065] The edge of the buffer 110 abuts against the edge of the support bar 400, which avoids stacking and thus reduces the vertical volume of the CTC battery pack.

[0066] For example, the buffer 110 can be foam, silicone pad, rubber pad or other materials with a certain degree of elasticity, and this application embodiment does not specifically limit it.

[0067] Reference Figure 4 and Figure 5 As shown, in some embodiments, the side of the buffer 110 facing the bottom guard plate 100 is flush with the side of the support bar 400 facing the bottom guard plate 100.

[0068] In the above embodiments, this enables the buffer 110 and the support bar 400 to form a stable support surface at the bottom of the cell module 500, preventing damage to the cell module 500 due to uneven force.

[0069] Reference Figure 4 and Figure 5 As shown, at least two support bars 400 are provided, and the at least two support bars 400 are overlapped. The sum of the thicknesses of the at least two support bars 400 is the same as the thickness of the buffer 110.

[0070] In the above embodiment, multiple support bars 400 are provided, and the multiple support bars 400 are overlapped, which can enhance the overall structural strength. At the same time, the number of support bars 400 can be adaptively adjusted according to the thickness of the buffer 110, thereby ensuring consistent thickness.

[0071] It is understood that there are at least two support bars 400, and the number of support bars 400 can be 2, 3, 4 or more. This application embodiment does not impose too many restrictions on this.

[0072] Reference Figure 4 and Figure 5 As shown, in some embodiments, the buffer 110 includes a first buffer portion 111 and a second buffer portion 112, which are disposed on opposite sides of the support bar 400 and are symmetrical with respect to the support bar 400.

[0073] In the above embodiments, the first buffer part 111 and the second buffer part 112 are symmetrically arranged so that when the bottom guard plate 100 is subjected to external impact, the impact force can be evenly distributed by the two parts, thus avoiding damage to the battery cell module 500 due to excessive force on one side.

[0074] Reference Figure 4 and Figure 5 As shown, in some embodiments, the support bar 400 has at least one connecting portion 420 for detachable connection with the mounting portion 310 on the vehicle body 300.

[0075] The support strip 400 abuts against the bottom guard plate 100 to enhance the structural strength of the bottom guard plate 100.

[0076] In the above embodiment, the support bar 400 can be detachably connected to the mounting part 310 on the vehicle body 300 through the connecting part 420. In this way, during assembly, the support bar 400 can be first bonded to the battery cell module 500, and then the support bar 400 can be fixed on the mounting part 310.

[0077] It also allows for easy and quick removal of the battery cell module 500 from the first mounting cavity, preventing the battery cell module 500 from sticking to the bottom cover plate 100 and thus avoiding additional disassembly steps.

[0078] For example, a detachable connection between the connecting part 420 and the mounting part 310 can be achieved by means of bolts, clips, pins, etc., and the embodiments of this application do not impose too many restrictions on this.

[0079] Reference Figure 4 and Figure 5 As shown, in some embodiments, the length of the support bar 400 is greater than the length of the cell module 500, and the portion of the support bar 400 that extends beyond the cell module 500 forms a connecting portion 420.

[0080] In the above embodiment, the structural design facilitates the assembly between the support bar 400 and the bottom protective plate 100, avoiding interference with the battery cell module 500.

[0081] Reference Figure 4 and Figure 5 As shown, in some embodiments, a first connector 410 is also included.

[0082] The connecting part 420 is provided with a connecting hole 421, and the first connecting member 410 is used to connect the connecting part 420 and the mounting part 310 on the vehicle body 300 through the connecting hole 421.

[0083] In the above embodiment, the first connector 410 can pass through the connecting hole 421 and connect to the mounting part 310 to fix the support bar 400 on the mounting part 310, thereby realizing a detachable connection between the support bar 400 and the mounting part 310.

[0084] Specifically, refer to Figure 4 and Figure 5 As shown, the support bar 400 has connecting portions 420 at both ends along the first direction. Both connecting portions 420 can be fixed to the mounting portion 310 by the first connector 410 to prevent rotation and improve the stability of the support bar 400 during installation.

[0085] In other embodiments, the bottom guard plate 100 may have a limiting groove, one end of the support bar 400 along the first direction is disposed in the limiting groove, and the other end of the support bar 400 along the first direction has a connecting part 420, which can also play the role of preventing rotation.

[0086] The first connector 410 is mainly used to connect the mounting part 310 and the support bar 400. For example, the first connector 410 can be a bolt, rivet bolt, pin lock, or other structure.

[0087] Reference Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the top cover 200 is a liquid cooling plate.

[0088] In the above embodiment, the liquid-cooled plate serves as the top cover 200 of the CTC battery pack, combining the functions of liquid cooling for the cell module 500 and flooring for the vehicle body 300. Compared to existing technologies, this design reduces the weight of the CTC battery pack and decreases its longitudinal volume, thereby increasing the longitudinal space of the vehicle's passenger compartment and improving passenger comfort.

[0089] Reference Figure 4 and Figure 6 As shown, in some embodiments, the liquid cooling plate includes a cold plate body 210 and a connector 220 connected together, and the cold plate body 210 is bonded to the battery cell module 500.

[0090] The cold plate body 210 has a liquid cooling channel, and the connector 220 is provided with a liquid outlet pipe 230 and a liquid inlet pipe 240. Both the liquid outlet pipe 230 and the liquid inlet pipe 240 are connected to the liquid cooling channel, and both the liquid outlet pipe 230 and the liquid inlet pipe 240 are inserted into the mounting part 310.

[0091] In the above embodiment, both the liquid outlet pipe 230 and the liquid inlet pipe 240 can be connected to an external liquid cooling device. The liquid cooling device delivers refrigerant to the cold plate body 210 through the liquid inlet pipe 240. The refrigerant flows in the liquid cooling channel and carries away the heat generated by the battery cell module 500, thereby dissipating heat and cooling the battery cell module 500. Then, the refrigerant flows back to the liquid cooling device through the liquid outlet pipe 230.

[0092] The mounting part 310 may be provided with a clearance hole, through which the liquid outlet pipe 230 and the liquid inlet pipe 240 can pass through the clearance hole and be installed on the mounting part 310. A sealing ring or sealant may be provided between the liquid outlet pipe 230 and the liquid inlet pipe 240 and the mounting part 310 to achieve a seal.

[0093] Reference Figure 3As shown, in some embodiments, the CTC battery pack provided in this application also includes an electrical unit 600 and a housing 700 disposed on the upper cover 200. The electrical unit 600 is disposed on the upper cover 200, and the housing 700 is detachably connected to the upper cover 200.

[0094] The top cover 200 is provided with a wiring hole 201, which is connected to the first mounting cavity. The outer shell 700 covers the electrical unit 600 and the wiring hole 201. The electrical unit 600 is electrically connected to the battery cell module 500 through the wiring hole 201.

[0095] The electrical unit 600 is electrically connected to the cell module 500. The electrical unit 600 can monitor the voltage, temperature, and charge / discharge status of the cell module 500 in real time to ensure that the cell module 500 operates within a safe range. The electrical unit 600 may include a BDU (Battery Disconnect Unit) and a BMS (Battery Management System).

[0096] In the above embodiment, by placing the electrical unit 600 on the upper cover 200, it is not necessary to occupy the space of the first mounting cavity. Under the premise of keeping the power of the cell module 500 unchanged, the volume of the first mounting cavity can be reduced, thereby reducing the volume of the CTC battery pack and improving the space utilization rate of the CTC battery pack on the vehicle body 300.

[0097] Reference Figure 3 As shown, the outer casing 700 covers the electrical unit 600 and the wiring hole 201. The outer casing 700 protects the electrical unit 600. The wiring harness 610 of the electrical unit 600 can pass through the wiring hole 201 into the first mounting cavity, thereby electrically connecting to the battery cell module 500. The wiring harness 610 may include power cords, connectors, etc., and the connectors may be copper busbars, aluminum busbars, etc.

[0098] Specifically, refer to Figure 3 and Figure 8 As shown, the CTC battery pack provided in this application embodiment also includes a mounting base 710, on which a through hole 711 is provided. The mounting base 710 is disposed on the upper cover 200, and the through hole 711 is correspondingly disposed with the wiring hole 201.

[0099] The housing 700 is connected to the mounting base 710 via the second connector 720 to form a second mounting cavity, and the electrical unit 600 is disposed in the second mounting cavity.

[0100] In the above embodiment, the mounting base 710 is mainly used to mount the electrical unit 600. The housing 700 is connected to the mounting base 710 to form a second mounting cavity for mounting the electrical unit 600. The wiring harness 610 of the electrical unit 600 can enter the first mounting cavity sequentially through the through hole 711 and the wiring hole 201.

[0101] The housing 700 and the mounting base 710 are detachably connected by a connector. This allows the housing 700 to be removed from the top cover 200 when the electrical unit 600 malfunctions, so that the electrical unit 600 can be repaired directly without cumbersome disassembly steps, thereby improving the efficiency of operation and maintenance.

[0102] For example, the connector can be a bolt, a rivet bolt, etc.

[0103] Reference Figure 3 As shown, the shape of the outer casing 700 can be adapted to the shape of the electrical unit 600 to avoid occupying too much space on the top cover 200, so as to make the overall structure of the CTC battery pack more compact.

[0104] Reference Figure 2 and Figure 7 As shown, in some embodiments, a wiring groove 311 may be provided on the mounting part 310. The wiring groove 311 extends along the extension direction of the mounting part 310 and communicates with the first mounting cavity. A portion of the wiring harness 610 of the electrical unit 600 is arranged in the wiring groove 311.

[0105] In the above embodiment, by arranging part of the wire harness 610 in the wiring groove 311, the wiring groove 311 can constrain and protect the wire harness 610, preventing the wire harness 610 from touching or rubbing against other components in the first mounting cavity, which could cause damage to the wire harness 610.

[0106] Meanwhile, the wire harness 610 is arranged along the extension direction of the wiring groove 311. The wiring groove 311 can guide the wiring layout of the wire harness 610 so that the wire harness 610 is neatly and orderly arranged in the first mounting cavity.

[0107] Reference Figure 1 As shown, in some embodiments, the upper cover 200 is connected to the seat fixing part 320 on the vehicle body 300, the seat fixing part 320 is connected to the mounting part 310, and the seat fixing part 320 is used to mount the seat of the vehicle body 300.

[0108] In the above embodiment, the seat fixing part 320 can be used to install the vehicle seat, and the upper cover 200 serves as the floor of the vehicle passenger compartment. By providing the connecting part 420 on the upper cover 200, the connection between the upper cover 200 and the vehicle body 300 is made tighter, and the structural strength of the upper cover 200 is improved, thereby preventing the occupants from bending and deforming the upper cover 200, which could damage the battery cell module 500.

[0109] Specifically, refer to Figure 2 and Figure 3 As shown, the vehicle body 300 has multiple spaced-apart seat fixing parts 320, and each seat fixing part 320 is connected to the upper cover 200.
