With the maturation of new energy power battery technology, especially the increasing maturity of integrated battery technology (CTP, CTC) for passenger vehicles, the disadvantages and contradictions of standard battery packs in commercial vehicles are becoming more and more apparent. Therefore, the application of CTP and CTC power batteries in commercial vehicles is being considered. Utility Model Content

[0041] The CCS integrated busbar assembly includes: a CCS tray 312, a plurality of series-parallel aluminum busbars 313 and a plurality of temperature sensors 314 disposed on the CCS tray 312, and a CCS slave control board 308, a data acquisition harness 307 and a data acquisition harness connector 310 disposed on the upper cover plate 304. The CCS tray 312 is mounted on the front and / or rear side of the blade battery cell 303 and is connected to the battery cell baffle 302.

[0046] In an optional embodiment, the CTP battery pack 300 is a double-layer cell, which is provided with two layers of cell trays 301. The bottom cell tray 301 has no thermal management structure, that is, no coolant inlet 3012 and coolant outlet 3013. Only the top cell tray 301 is provided with a thermal management structure. It is also provided with two layers of blade cells 303. The lower and upper surfaces of the top cell tray 301 are coated with adhesive, and the upper surface of the bottom cell tray 301 is coated with adhesive to bond the blade cells 303.

[0047] Preferably, the upper and lower surfaces of the cell tray are coated with thermally conductive structural adhesive to bond the upper and lower blade cells respectively, while also providing thermal management for the upper and lower blade cells.

[0048] Furthermore, the cell connection system (CCS), which is composed of blade cells 303, acquisition harness / FPC, aluminum busbars, plastic parts, etc., integrated by hot pressing or riveting, is responsible for the series and parallel connection of cells and the acquisition and transmission of voltage / temperature.

[0049] Specifically, the battery cell connection system (CCS) includes: a blade battery cell 303, several shock-absorbing foams 305 and several CSC fixing brackets 306 disposed above the upper cover plate 304, a data acquisition harness 307, a CSC slave control board 308, a fire detector 309, a data acquisition harness connector 310, and a data acquisition harness fixing clip 311. The CSC slave control board 308 is connected to the data acquisition harness connector 310. The data acquisition harness 307 connected to the data acquisition harness connector 310 is fixed above the upper cover plate 304 by the data acquisition harness fixing clip 311. The other end of the data acquisition harness 307 connected to the data acquisition harness connector 310 is connected to several temperature sensors 314 and battery cell series-parallel aluminum busbars 313 mounted on the CCS support plate 312. The CSC slave control board 308 is mounted via the CSC fixing brackets 306.

[0050] The lower enclosure 200 of the PACK includes: a lower cell tray fixing boss 21 located at the bottom of the enclosure, an upper cell tray fixing bracket 22 and an upper cell tray fixing boss 23 located in the enclosure, and a plurality of PACK top cover fixing points 24, a plurality of battery pack and vehicle frame lifting points 25 and battery pack mounting positioning pins 26 formed at the upper end of the enclosure.

[0051] The lower cell tray fixing boss 21 is provided with a lower cell tray fixing point 211, which is engaged with the cell tray fixing point 3011 on the bottom cell tray 301 of the CTP battery pack 300 by screws; the upper cell tray fixing point 231 on the upper cell tray fixing boss 23 is equipped with an upper cell tray fixing bracket 22 by screws, which is engaged with the cell tray fixing point 3011 on the upper cell tray 301 of the multi-layer CTP battery pack 300 by screws. The upper end of the housing has several PACK cover fixing points 24 and several battery pack and frame mounting points 25, which are respectively used to mate with the PACK cover and CTP battery pack 300 for installation. Preferably, the several PACK cover fixing points 24 and several battery pack and frame mounting points 25 are spaced apart, and the battery pack and frame mounting points 25 are fixed nuts. The battery pack mounting positioning pins 26 are used to pre-position the PACK lower housing 200 and the PACK cover for installation, which facilitates installation.

[0052] Preferably, the upper battery cell tray fixing bracket 22 is Z-shaped, and each horizontal part of the Z-shape is provided with a fixing point, namely a first fixing point 221 and a second fixing point 222. The first fixing point 221 is used to cooperate with the upper battery cell tray 301, and the second fixing point 222 is used to install the upper battery cell tray fixing bracket 22 onto the upper battery cell tray fixing boss 23 by screws.

[0053] The outer side of the PACK enclosure houses components such as the battery pack total positive output 29, an explosion-proof valve 30, a high-voltage wiring harness fixing bracket 31, a low-voltage communication interface 32, a battery pack liquid cooling pipe interface 33, a grounding point 34, a battery pack total negative output 35, and a maintenance switch MSD 36. Preferably, in this embodiment, all these components are located on the same side of the PACK enclosure. In this embodiment, the PACK enclosure is T-shaped, and these components are located at the head of the T-shape. Reinforcing ribs 27 are provided on both sides of the connection between the head and the lower part of the T-shape, and an explosion-proof valve 30 is also provided at the lower part.

[0054] The battery pack's total positive output 29 and total negative output 35 are ports for outputting DC high-voltage power from the battery pack. They are responsible for powering the motor controller during operation and receiving power from the charging station during charging. The battery pack's total positive output 29 and total negative output 35 are directly connected to both ends of the series-connected cell cluster inside the battery pack. They are connected to the main contactor, typically inside or near the service switch MSD module, and a fuse via a high-voltage copper busbar. The service switch MSD36 is used to blow in case of severe overcurrent or short circuit, protecting the battery pack and high-voltage lines. The low-voltage communication interface 32 is directly connected to the main control board of the battery management system via a low-voltage wiring harness, serving as a channel for signal communication between the CTP battery pack and the vehicle controller. The battery pack liquid cooling pipe interface 33 is connected to the liquid cooling plate inside the CTP battery pack via liquid cooling pipe 37. Typically, there is a pair of interfaces, one for coolant inlet and one for coolant outlet, to connect to the vehicle's thermal management system, forming a coolant circulation loop. The explosion-proof valve 30 is directly connected to the internal space of the CTP battery pack. When the internal pressure of the CTP battery pack becomes too high due to abnormal conditions such as thermal runaway of the cells, the explosion-proof valve will automatically open to quickly release the high-pressure gas and prevent the battery pack casing from bursting due to excessive pressure. The grounding point 34 reliably electrically connects the metal structure of the PACK lower enclosure to the vehicle chassis / frame through bolts and grounding wire harness, providing a common reference potential for the high-voltage system and preventing the casing from becoming live due to insulation failure, thus avoiding the risk of electric shock to personnel. The high-voltage wire harness fixing bracket 31 is used to fix and guide the high-voltage wire harness leading from the main positive and main negative interfaces to the vehicle outside the CTP battery pack.

[0055] The installation method of the integrated CTP battery pack mounting structure for commercial vehicles according to this utility model is as follows:

[0056] The integrated CTP battery pack 300 is installed in the PACK box and fixed with bolts using the battery mounting frame 100 integrated with the vehicle frame longitudinal beam 400. The PACK box is installed from bottom to top. In addition, the cells of the CTP battery pack 300 are directly installed in the battery pack housing, replacing the traditional "cell → module → pack" battery pack solution, improving space utilization and energy density.

[0057] Specifically, the assembly of the CTP battery pack 300 is as follows: First, the cell tray 301 is welded together with the cell baffles 302 at both ends of the cell. Thermally conductive structural adhesive is applied to the bottom of the cell tray 301. Then, the cell is clamped and placed into the cell tray 301 using tooling equipment. Finally, the top cover plate 304 is placed on top and bolted to the cell baffles 302 at both ends of the cell.

[0058] After the CTP battery pack 300 is assembled and manufactured, it is installed in the lower box of the PACK. The lower cell tray 301 is first fixed to the lower cell tray fixing boss 21 with bolts. Then, the upper cell tray fixing bracket 22 is fixed to the upper cell tray fixing boss 23 with bolts. Finally, the upper cell tray 301 and the upper cell tray fixing bracket 22 are bolted together and fixed.

[0059] The lower housing of the PACK is a "T"-shaped structure made of aluminum extrusion profiles welded together. Two beams running through the front and back divide the lower housing into three chambers. The two beams running through the front and back improve the overall rigidity and strength of the battery pack. The three chambers are interconnected and use an integrated PACK top cover. A foam sealing strip is used between the PACK top cover and the lower housing. The sealing strip is compressed by bolts to fix the top cover. The lower housing has a flange around its perimeter with special points for mounting to the vehicle frame. The lower housing is the main load-bearing structure.

[0060] This utility model also includes a vehicle equipped with the integrated CTP battery pack mounting structure for commercial vehicles.

[0061] The integrated CTP battery pack of this invention has the following advantages compared to the traditional standard pack:

[0062] Traditional standard battery pack solutions have low energy density, making it difficult to achieve vehicle lightweighting. They use standard battery boxes with separate layouts, which offer flexibility. However, each battery box must meet national standards, such as resistance to random vibration, impact, compression, and waterproofing. Although a single standard box has a simple design and high energy density, calculating the energy density of multiple battery packs together, especially with the addition of battery brackets, reduces the overall energy density, increasing the difficulty of vehicle lightweighting and resulting in higher vehicle energy consumption. In contrast, the CTP battery pack solution eliminates the complex process of assembling cells into modules, modules into standard packs, and standard packs into the vehicle battery system. It directly integrates the cells into the pack, significantly improving energy density.

[0063] Traditional standard package solutions have low space utilization, compressing the layout space for other functional components in the vehicle, resulting in low overall vehicle space utilization. The traditional longitudinal beam + standard package layout scheme occupies a large space, compressing the layout space for other functional components. In contrast, the integrated CTP battery pack for commercial vehicles is uniformly installed through the PACK box, and then simultaneously utilizes the vehicle frame longitudinal beams and universal casting brackets, resulting in high space utilization and saving a lot of space for the layout of other functional components.

[0064] In summary, the integrated CTPCTP battery pack and its mounting structure not only improve the energy density of the entire vehicle, but also enhance the space utilization of the vehicle.

[0065] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
