An intelligent assembly method was designed to realize the intelligent assembly of the profiled thermal battery pack and improve its assembly accuracy. Firstly, for the number and size of different monomer batteries vary, this paper takes the monomer battery thermal battery assembly as the object, with a common shape circle assembly screw arrangement and an established process model. Then, the assembly also has an improved differential evolution algorithm for assembly arrangement and process, on the number, location, tightening of the screw assembly, torque, and the order of solution. According to this scheme, the assembly and the flatness test were carried out. Results showed that the bottom plate of the assembly frame was “concave in the middle and warped around,” and the flatness error was large. The scheme was optimized by numerical simulation analysis. After optimization, the average offset of the floor plane was 0.04 mm, the offset accounted for 0.028% of the overall height, the maximum offset was 0.094 mm, and the offset was reduced by 0.312%.
