2. Mechanism-Perspective Impact Analysis
CT inspection equipment is placed in the final inspection zone through which the cell passes after assembly. The positional repeatability of the inspection stage determines image quality. If stage stiffness is insufficient, vibration during rotation appears as image blur.
ESS LFP cells tend to be larger than EV cells (estimate; form factor undisclosed). As cell mass increases, both the inertial load on the rotating stage and the gripper clamping load increase together. This load must be absorbed by the stage bearing arrangement and base frame stiffness.
When identical equipment is installed across 3 lines, the cell transfer interface (infeed height, pitch, gripping surface) becomes standardized. On the line design side, the height reference plane of the conveyors before and after the inspector can be aligned at once.

Design Reflection Checklist
- Confirm external cell dimensions for the three lines (273Ah, large prismatic, 300Ah)
- Size gripper clamp stroke margin for the largest cell
- Review rotary stage bearing layout and base frame stiffness for heavier cells
- Review how far cell loading height, pitch and gripping faces can be standardized
One-Line Summary
When CT inspection equipment is installed simultaneously across 3 LFP lines, the cell transfer reference plane in the inspection zone becomes standardized, and stage stiffness under large-cell rotational load becomes a design review item.
