Research on the Orthogonal Test of Spot Welding Parameters of power battery packs

摘要

Due to the complexity in the process of the welding, the welding parameters selection and reasonable matching will influence the quality of the power battery joints. There are not specific mathematical models between the welding parameter and the welding quality in the current period and the selection of the welding parameters is only depended on experience. In this paper, the orthogonal test is conducted on the main technological parameter of the welding of power battery packs and the optimal combination of parameters is gained after the analysis of the results of the test, which promotes the quality of the spot welding of power battery packs in series connection and in parallel connection.
