Next, the lifting cylinder 19 lifts the battery cell tray 16. Then, the longitudinal movement control component 11 moves the detection component 13 above the standard battery cell 6. The lifting control component 12 lowers the detection component 13 to contact the standard battery cell 6 and read its parameters. Then, the lifting control component 12 raises the detection component 13.

Under the action of lifting control component 12 and longitudinal movement control component 11, OCV / ACIR testing of several rows of cells in cell tray 16 is completed sequentially. After the test is completed, lifting cylinder 19 drives cell tray 16 to descend onto corner frame 17. Then, blocking control cylinder 24 controls blocking frame 25 to avoid cell tray 16. At this time, cell tray 16 is moved to second conveying component 3 and conveyed to subsequent sorting station.
