[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] See Figures 1 to 3 , a BMS bracket for a new energy vehicle battery pack, having:

[0021] The bracket body 1 is strip-shaped, and there are two bracket bodies 1 in total; two BMSs 2 are respectively connected to the two sides of the two bracket bodies 1; the bracket body 1 is a trough-shaped structure, and one side wall 12 is provided on each side of the bracket body 1, and one BMS 2 is connected to one side wall 12. The frame solution of the split bracket is adopted, which reduces material waste; the battery pack BMS can be installed on both sides, and the installation efficiency is high.

[0022] The bracket body 1 is provided with a projection welding nut 3, and the BMS is connected to the bracket body 1 through the projection welding nut 3. Changing from the original nut spot welding to the projection welding nut 3 greatly reduces the welding workload, reduces the requirements for welding quality, improves work efficiency, and improves product quality.

[0023] The bracket body 1 is also provided with weight-reducing holes 11, which play a role in weight reduction and can reduce materials at the same time.

[0024] The height of the upper end of the bracket body 1 is not higher than the height of the upper end of the BMS. The fixed height of the BMS on the BMS bracket is reduced to avoid the problems of wire harness wear and interference.

[0025] A gap is formed between two BMSs 2 through the bracket body 1, facilitating the wire harness to pass through.

[0026] One projection welding nut 3 is provided at each of the upper and lower ends of the bracket body 1. The upper and lower ends of the BMS are connected through the projection welding nuts 3 at the upper and lower ends of the bracket body 1, and the installation is stable and reliable.

[0027] A cylindrical hollow tube structure is adopted, and weight-reducing holes are designed; through size matching and welding position matching, the convenience of projection welding is achieved, the enhanced fixation of the BMS is ensured, and finally the work efficiency and product quality are improved.

[0028] After adopting the above structure, a frame scheme of a split bracket is adopted, reducing material waste; battery pack BMSs can be installed on both sides, and the installation efficiency is high.
