[0048] 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.

[0049] As mentioned in the background section, the CTC battery pack has a mounting cavity in which cell modules and electrical units (such as BDU, BMS, etc.) are installed. The electrical units are electrically connected to the cell modules via wiring harnesses. The electrical units are used to monitor information such as voltage, temperature, and charge / discharge status of the cell modules in real time to ensure that the cell modules operate within a safe range.

[0050] However, the wiring harness of the electrical unit is located inside the mounting cavity, making it prone to contact and wear with other components inside the mounting cavity, which can lead to damage to the wiring harness.

[0051] 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 protective plate, a top cover, a wiring channel, a cell module, and a wiring harness.

The wiring channel is disposed on the mounting portion and communicates with the first mounting cavity. The cell module is disposed within the first mounting cavity, and the wiring harness is electrically connected to the cell module, with at least a portion of the wiring harness arranged within the wiring channel. By providing a wiring channel on the mounting portion and arranging the wiring harness within it, the wiring channel protects the wiring harness and reduces damage. Simultaneously, the wiring harness is arranged along the extension direction of the wiring channel, which guides the wiring layout, ensuring a neat and orderly arrangement of the wiring harness.

[0052] The following describes exemplary application scenarios of this utility model.

[0053] 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 provides wiring channels on the mounting part, which are used to arrange the wiring harnesses and protect them, thus reducing damage to the wiring harnesses.

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.

[0055] Reference Figures 1 to 10 As shown in the embodiment of this application, the CTC battery pack includes a bottom protective plate 100, a top cover 200, a wiring channel 311, a cell module 400, and a wiring harness 600.

[0056] The bottom guard plate 100 and the top cover 200 are respectively used to connect with the mounting part 310 on the vehicle body 300 to form a first mounting cavity. The wiring groove 311 is used to be disposed on the mounting part 310 and communicates with the first mounting cavity. The battery cell module 400 is disposed in the first mounting cavity, and the wiring harness 600 is electrically connected to the battery cell module 400. At least a portion of the wiring harness 600 is arranged in the wiring groove 311.

[0057] Reference Figure 4 and Figure 5 As shown, by providing a wiring groove 311 on the mounting part 310 and arranging the wire harness 600 in the wiring groove 311, the wiring groove 311 can accommodate and protect the wire harness 600, preventing the wire harness 600 from being squeezed or rubbed by other components in the first mounting cavity and thus extending the service life of the CTC battery pack.

[0058] Furthermore, the wire harness 600 is arranged along the extension direction of the wiring groove 311. The wiring groove 311 can guide the wiring layout of the wire harness 600 so that the wire harness 600 is arranged neatly and orderly in the first mounting cavity.

[0059] Understandably, the CTC battery pack also includes an electrical unit 500, which is electrically connected to the cell module 400 via a wiring harness 600. The electrical unit 500 is used to monitor the voltage, temperature, and charge / discharge status of the cell module 400 in real time, ensuring that the cell module 400 operates within a safe range. The electrical unit 500 may include a BDU (Battery Disconnect Unit) and a BMS (Battery Management System). The wiring harness 600 may include power lines, connectors, etc., where the connectors can be copper busbars, aluminum busbars, etc.

[0060] Reference Figure 1 , Figure 2 and Figure 3As 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 400. The mounting portion 310 acts as 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.

[0061] For example, refer to Figure 6 and Figure 7 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.

[0062] At least a portion of the wire harnesses 600 are arranged in the wiring trough 311. For example, some wire harnesses 600 may be arranged in the wiring trough 311, or all wire harnesses 600 may be arranged in the wiring trough 311. This application embodiment does not impose too many restrictions on this.

[0063] In summary, the CTC battery pack provided in this application embodiment, by providing a wiring groove 311 on the mounting part 310, arranges the wiring harness 600 within the wiring groove 311, thereby protecting the wiring harness 600 and reducing damage to it. Simultaneously, the wiring harness 600 is arranged along the extension direction of the wiring groove 311, which guides the wiring layout of the wiring harness 600, ensuring a neat and orderly arrangement.

[0064] Reference Figure 3 , Figure 7 and Figure 8 As shown, in some embodiments, the CTC battery pack provided in this application also includes an electrical connector 700, which is disposed on the mounting portion 310 and electrically connected to the wiring harness 600. The electrical connector 700 is used for electrical connection with the electrical system of the vehicle body 300.

[0065] In the above embodiment, the electrical connector 700 is electrically connected to the cell module 400 and the electrical unit 500 via the wiring harness 600. The electrical connector 700 can be connected to the electrical system on the vehicle body 300 so as to provide electrical energy to the electrical system through the CTC battery pack, or to collect data such as temperature and voltage of the cell module 400 in the CTC battery pack through the electrical system.

[0066] Reference Figure 3 , Figure 7 and Figure 8As shown, in some embodiments, an installation gap 110 is formed on the upper part of the bottom cover plate 100 and between the battery cell module 400 and the mounting part 310. The electrical connector 700 is located in the installation gap 110, and the wire harness 600 is arranged sequentially along the installation gap 110 and the wiring groove 311.

[0067] In the above embodiment, there is an installation gap 110 between the battery cell module 400 and the mounting part 310. The installation gap 110 can provide installation space for some of the wire harness 600 and electrical connectors 700, so as to avoid them being squeezed by the battery cell module 400 and damaged.

[0068] Reference Figure 7 and Figure 8 As shown, some of the battery cells in the electrical connector 700 and battery cell module 400 can be electrically connected to a portion of the wire harness 600 located within the installation gap 110, and other battery cells in the battery cell module 400 can be electrically connected to a portion of the wire harness 600 located within the wiring trough 311.

A sealing ring or sealant may be provided between the electrical connector 700 and the mounting part 310 to achieve a seal.

[0070] For example, electrical connector 700 may include high-voltage connectors, low-voltage connectors, etc.

[0071] Reference Figure 7 and Figure 8 As shown, in some embodiments, the electrical connector 700 includes at least one first plug portion 710 and at least one second plug portion 720. Both the first plug portion 710 and the second plug portion 720 are electrically connected to the wiring harness 600. The first plug portion 710 passes through a first side of the mounting portion 310, and the second plug portion 720 passes through a second side of the mounting portion 310. The first plug portion 710 and the second plug portion 720 are used to plug into or disconnect from the electrical system to electrically connect to or disconnect from the electrical system.

[0072] In the above embodiment, the electrical connector 700 includes at least one first connector 710 and at least one second connector 720, through which the CTC battery pack is electrically connected to multiple electronic devices on the electrical system. Furthermore, the first connector 710 is located on a first side of the mounting portion 310, and the second connector 720 is located on a second side of the mounting portion 310, thereby facilitating electrical connection with electronic devices in different locations.

[0073] Reference Figure 7 and Figure 8As shown, in some embodiments, the mounting gap 110 includes a first mounting gap 111 and a second mounting gap 112. The first mounting gap 111 is formed by the first side of the cell module 400 and the mounting part 310, and the second mounting gap 112 is formed by the second side of the cell module 400 and the mounting part 310. The wire harness 600 is arranged sequentially along the first mounting gap 111, the wiring groove 311 and the second mounting gap 112.

[0074] In the above embodiment, the first connector 710 can be installed in the first mounting gap 111, and the second connector 720 can be installed in the second mounting gap 112. When arranging the wire harness 600, it can be arranged sequentially along the first mounting gap 111, the wiring groove 311, and the second mounting gap 112, which can make the wire harness 600 neatly and orderly arranged in the first mounting cavity, reducing damage to the wire harness 600.

[0075] Reference Figure 7 and Figure 8 As shown, in some embodiments, the first mounting gap 111 and the second mounting gap 112 are arranged opposite to each other.

[0076] In the above embodiment, the first connector 710 and the second connector 720 are arranged opposite to each other, and the wire harness 600 is arranged sequentially along the first mounting gap 111, the wiring groove 311 and the second mounting gap 112. The first connector 710 and the first part of the battery cells in the battery cell module 400 can be electrically connected to the part of the wire harness 600 in the first mounting gap 111. The second part of the battery cells in the battery cell module 400 can be electrically connected to the part of the wire harness 600 in the wiring groove 311. The second connector 720 and the third part of the battery cells in the battery cell module 400 can be electrically connected to the part of the wire harness 600 in the second mounting gap 112.

[0077] The above wiring method allows the wire harness 600 to be arranged neatly and orderly in the first mounting cavity, avoiding repeated winding of the wire harness 600, thereby reducing the length of the wire harness 600 and facilitating wiring.

[0078] Among them, reference Figure 6 and Figure 7 As shown, the first mounting gap 111 and the second mounting gap 112 are arranged opposite to each other, that is, the first side and the second side of the mounting part 310 are arranged opposite to each other. The first side of the mounting part 310 can be the first crossbeam 313 and the second side can be the second crossbeam 314.

[0079] Specifically, refer to Figure 1 , Figure 6 and Figure 7As shown, the first crossbeam 313 corresponds to the rear body of the vehicle body 300, the second crossbeam 314 corresponds to the front body of the vehicle body 300, and the two sill beams 312 correspond to the left and right doors on the vehicle body 300, respectively. The first connector 710 is inserted into the first crossbeam 313, and the second connector 720 is inserted into the second crossbeam 314. This facilitates electrical connection between the first connector 710 and electronic equipment on the rear body of the vehicle body 300, and between the second connector 720 and electronic equipment on the front body of the vehicle body 300.

[0080] It is understood that there is at least one first connector 710, and the number of first connectors 710 can be one, two or more. There is at least one second connector 720, and the number of second connectors 720 can be one, two or more. The embodiments of this application do not impose too many restrictions on this.

[0081] Reference Figure 3 and Figure 6 As shown, in some embodiments, the CTC battery pack provided in this application also includes an electrical unit 500. The electrical unit 500 is disposed on the upper cover 200 and located outside the first mounting cavity. The upper cover 200 is provided with a wiring hole 201, which is correspondingly disposed with the first mounting gap 111.

[0082] The electrical unit 500 is set in correspondence with the first installation gap 111, and the wire harness 600 is electrically connected to the electrical unit 500 through the wiring hole 201.

[0083] In the above embodiment, the electrical unit 500 is disposed on the upper cover 200, and the wiring harness 600 can be electrically connected to the electrical unit 500 through the wiring hole 201 on the upper cover 200. In this way, the electrical unit 500 is disposed on the outside of the first mounting cavity, without occupying the space of the first mounting cavity. While keeping the power of the cell module 400 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.

[0084] The electrical unit 500 corresponds to the first mounting gap 111 and is mounted on the upper cover 200. This allows the wiring harness 600 to be electrically connected to the electrical unit 500 sequentially through the first mounting gap 111 and the wiring hole 201, thereby reducing the length of the wiring harness 600. For details, refer to... Figures 1 to 3 As shown, the electrical unit 500 is located above the cover 200 and at the floor position of the vehicle body 300.

[0085] Reference Figure 6 and Figure 9 As shown, in some embodiments, the top cover 200 is a liquid cooling plate.

[0086] In the above embodiment, the liquid cooling plate serves as the top cover 200 of the CTC battery pack, which can simultaneously perform the functions of liquid cooling heat dissipation for the cell module 400 and the floor function of the vehicle body 300. Compared with the prior art, this design can reduce the weight of the CTC battery pack and reduce the longitudinal volume of the CTC battery pack, thereby increasing the longitudinal space of the vehicle's passenger compartment and improving passenger comfort.

[0087] The battery cell module 400 and the liquid cooling plate can be connected with glue to improve the stability of the battery cell module 400 installation.

[0088] Reference Figure 6 and Figure 9 As shown, in some embodiments, the liquid cooling plate includes a cold plate body 210 and a connector 220 connected together.

[0089] 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.

[0090] 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 400, thereby dissipating heat and cooling the battery cell module 400. Then, the refrigerant flows back to the liquid cooling device through the liquid outlet pipe 230.

[0091] 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 be inserted into 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.

[0092] Specifically, refer to Figure 6 As shown, the connector 220 can be located within the second mounting gap 112 to avoid squeezing or colliding with the battery cell module 400, which could cause damage.

[0093] Reference Figure 9 As shown, in some embodiments, at least one support strip 120 is provided on the bottom protective plate 100, and the battery cell module 400 is bonded to the support strip 120.

[0094] In the above embodiment, by providing the support strip 120, the structural strength of the bottom protective plate 100 can be increased and the deformation of the bottom protective plate 100 can be reduced. At the same time, the support strip 120 can also help support the individual cells in the cell module 400 to improve the stability of the overall structure.

[0095] Among them, reference Figure 9 As shown, multiple support strips 120 can be spaced apart on the bottom protective plate 100, and each support strip 120 is bonded to the battery cell module 400.

[0096] Reference Figure 9 As shown, in some embodiments, at least one buffer pad 130 may be provided on the bottom protective plate 100, and the buffer pad 130 abuts against the battery cell module 400.

[0097] In the above embodiment, by setting the buffer pad 130, the deformation of the bottom protective plate 100 can be prevented from damaging the battery cell module 400.

[0098] For example, the seal can be made of elastic materials such as silicone pads, rubber pads, or foam, and this application does not impose any restrictions on this.

[0099] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the upper cover 200 is connected to the connecting portion 320 on the vehicle body 300, the connecting portion 320 is connected to the mounting portion 310, and the connecting portion 320 is used to mount the seat of the vehicle body 300.

[0100] In the above embodiment, the connecting 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 320 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 400.

[0101] Specifically, refer to Figure 2 and Figure 3 As shown, the vehicle body 300 has multiple spaced connecting parts 320, each of which is connected to the upper cover 200.

[0102] Reference Figure 2 , Figure 3 and Figure 10 As shown, in some embodiments, the CTC battery pack provided in this application also includes a housing 800, which is detachably disposed on the top cover 200.

[0103] The outer casing 800 and the upper cover 200 form a second mounting cavity, and the electrical unit 500 is disposed in the second mounting cavity.

[0104] In the above embodiment, the upper cover 200 is placed over the electrical unit 500, which can protect the electrical unit 500. Furthermore, the outer casing 800 is detachably connected to the upper cover 200. This allows the outer casing 800 to be removed from the upper cover 200 to directly repair the electrical unit 500 in case of a malfunction, avoiding cumbersome disassembly steps and thus improving the efficiency of operation and maintenance.

[0105] Specifically, refer to Figure 3 and Figure 10 As shown, a mounting base 810 can be provided on the upper cover 200. The outer shell 800 and the mounting base 810 are detachably connected by a connector 820 to form a second mounting cavity. The electrical unit 500 is disposed in the second mounting cavity. A through hole 811 is provided on the mounting base 810. The through hole 811 communicates with the wiring hole 201.
