01

Project Priorities & Engineering Response

4 Workstreams

The project required coordinated verification of multiple automated lines, different pouch cell models and the interfaces connecting mechanical, electrical, control and data-acquisition systems.

A

Coordinate Multiple Cell Models

TOB engineering responseReviewed the process flow and equipment interfaces across multiple pouch cell specifications so each line could be evaluated against its approved technical agreement.

B

Verify Complete Automated Lines

TOB engineering responseCovered mechanical assembly, electrical control, automation commissioning and data acquisition as connected systems rather than isolated machines.

C

Execute a Structured FAT

TOB engineering responseWorked through equipment performance, precision, capacity and safety requirements item by item during an on-site FAT program lasting more than three months.

D

Extend Technical Support

TOB engineering responseCombined integrated-line project support with technical consulting, expanding the service scope beyond equipment supply alone.
