[0012] The beneficial effects of the utility model are:

[0013] 1. This battery collection and heating integrated CCS, by combining the collection harness and the heater to form a heating and signal collection body, replaces the traditional collection signal line which usually can only be used for collection through traditional silicone wire and single PCB-A adapter. The heater usually needs to be attached to the side panel or the top and bottom of the battery pack for heating. The new technology integrates the collection and heating process, making the battery collection and thermal management functions more modular, reducing production labor costs, reducing quality risks caused by assembly failure, and reducing production costs. By integrating the collection harness and the heater into one platform, the original upper harness bracket can also be cancelled, and the collection harness end product is converged to the side and integrated with the heater, saving upper space and parts.

[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] like Figures 1 to 5 As shown, the utility model provides a battery collection and heating integrated CCS, including an upper cell constraint frame 1, an upper cell bus 2 and a heating and signal collection body 3. The upper cell constraint frame 1 is fixedly installed with the upper cell bus 2 on the top, and the heating and signal collection body 3 is fixedly installed with the top of the upper cell bus 2. The heating and signal collection body 3 includes a collection harness 301, a heating element 302, epoxy PP303 and a collection terminal 304. The collection harness 301 is fixedly installed on the top of the upper cell bus 2, the heating element 302 is fixedly installed on the front of the collection harness 301, the epoxy PP303 is fixedly installed on the bottom of the collection harness 301 and the heating element 302, and the collection terminal 304 is fixedly connected to the back of the collection harness 301.

[0023] refer to Figure 1 , Figure 4 and Figure 5 A connecting terminal 4 is provided on the right side of the collection harness 301, a harness socket 5 is fixedly installed on the right side of the connecting terminal 4, a lower battery cell constraint frame 6 is fixedly installed on the bottom of the upper battery cell constraint frame 1, and a placement cavity 7 is opened in the inner cavity of the upper battery cell constraint frame 1 and the lower battery cell constraint frame 6.

[0024] The above solution is adopted: by setting the placement cavity 7, it is convenient to combine and install multiple battery cells inside the upper battery cell constraint frame 1 and the lower battery cell constraint frame 6, saving the internal space of the battery and improving the space utilization.

[0025] refer to Figure 1 , Figure 2 and Figure 3 The bottom of the lower cell restraint frame 6 is fixedly mounted with a lower cell busbar 8, and the front of the heating element 302 is fixedly mounted with a series aluminum row 9, and the heating element 302 is composed of brass and copper.

[0026] The above scheme is adopted: by changing the raw material structure of the heating element 302 itself from the original brass to synthesize brass and copper materials through material cutting and polymer welding process, the requirements of collecting voltage resistance and high temperature generated by the heating element 302 are met, the thermal conductivity and corrosion resistance of the material are improved, and at the same time the overall weight is reduced, which helps to improve the efficiency and service life of the battery pack.

[0027] Working principle:

[0028] When in use, metal materials are manufactured through polymer diffusion welding or high-temperature welding, and can also be mechanically rolled to form a metal substrate for the heat source and signal line collection harness 301. After the heating element 302 and the signal collection harness 301 are converted by optical equipment, an acidic chemical solution is used to etch out the set resistance circuit and collection line, and the insulating film and PP material are mounted on the surface to solidify to form a soft-hard combination substrate. The manufactured substrate is transferred to the SMT equipment to mount various packaging components and perform UV glue sealing and waterproofing treatment. The substrate is mounted on the upper battery bus 2 and laser-bonded with the series aluminum bus 9. After assembly, it can be directly loaded on the battery pack to power on and collect battery data, and simultaneously heat the battery.

[0029] In summary: this battery collection and heating integrated CCS, through the coordinated use of the collection harness 301 and the heating element 302, solves the problem that the existing collection signal line can usually only be used for collection through traditional silicone wires and single PCB-A adapters, and the heating element usually needs to be attached to the side panel or the top and bottom of the battery pack for heating, which leads to an increase in the number of auxiliary materials and parts required for the battery module. Both products need to be installed and manufactured separately, the process is complicated, the battery pack space is occupied, the production cost is high, and the maintenance failure rate is high.
