AI Technical Summary
Existing formation cabinets cannot accommodate various types of batteries, especially when the two tabs of the battery are located at both ends of the battery, making formation impossible, and they cannot be adapted to battery size.
A formation fixture was designed, comprising multiple charging contact mechanisms and a formation layer. By combining the first, second, and third contact components, the size of the accommodating area can be adjusted according to the position of the battery tabs, thus achieving adaptation to different batteries.
It achieves compatibility with different batteries, improves the applicability and convenience of formation fixtures, has a simple structure, and can adapt to batteries of different sizes for formation work.
