FAT and SAT for battery equipment: what to test where

A factory acceptance test in China and a site acceptance test at your plant check different things. Plan both before you sign.

Water left in electrodes and separators reacts with the electrolyte. Post-drying and the dry room exist to keep it out.

The last steps of cell production take days and much of the floor space. The equipment quote should say exactly which recipe it can run.

Sorting machines and testers quote OCV, ACIR and DCIR. They answer different questions and cannot be swapped for each other.

Choose cell and pack test equipment from the battery and the test plan, then read every accuracy figure with its range.

Pieces per minute means something only next to the electrode length, the cell geometry and how the output was counted.

Three width figures describe three different parts of an electrode coater. Keep them apart and the comparison stays honest.
