Cylindrical Cell Grading Machine
High-precision forming, grading, and cycle-life testing for cylindrical cells — from formation to automatic quality sorting in one machine.
- •Forms, grades and cycle-life tests cylindrical cells in one machine
- •Regenerative discharge feeds energy back to the grid — up to 80% efficiency
- •±0.05% F.S voltage and current accuracy with digital DSP control
- •256–512 independent channels; wide-tray, narrow-tray and needle variants
- •Fits cells from 18–60 mm diameter and 45–256 mm length
- •Auto-sorts cells by quality in a single step
