Abstract: Trial-manufacture of power batteries usually has the characteristics of simultaneous development of multiple projects, complex and changeable technology and various types of work. Based on the experience of the trial-manufacture of electric vehicle for many years, the quality control method suitable for the trial-manufacture process of power battery sample package is formed, which involves factors such as prototype parts, processing technology, process flow, personnel, tools and fixture, sample inspection, sample cleanliness assurance, sample assembly verification, sample restructuring control, tightening process, gluing process, press-fitting process, gap inspection, sealing inspection, process quality control and tooling process quality control are described in detail. The quality control system of all elements in the whole process of power battery sample package is perfected, and the quality of trial-manufacture is guaranteed.

Key words: quality control; trial-manufacture process; process; fixture
