In modern electric vehicle (EV) battery pack manufacturing, precision cell staging and high-speed laser welding require ultra-reliable control signals, zero mechanical loosening under constant robotic vibration, and stringent OT cybersecurity under IEC 62443.
Project Challenges
The customer faced high ambient electromagnetic noise from high-frequency laser welding units, tight space inside localized robot control cabinets, and the critical need to prevent microsecond signal dropouts during automated pack transfer.
Engineered Solution Architecture:
- CLIPLINE Complete PT 2,5 Push-in Terminals: Vibration-proof spring connections eliminating regular re-torquing during aggressive 3-axis robot movement.
- FL SWITCH 2208 Managed PROFINET Switches: Deterministic real-time cell transfer synchronization with MRP ring redundancy under 15ms recovery.
- QUINT4-PS 24V DC / 20A Power Supplies with SFB Technology: Dynamic reserve tripping faulty branches within milliseconds while keeping PLC processors online.
Operational Results & Impact
The implementation delivered continuous 24/7 assembly uptime across 4 parallel production shifts. Zero signal loss was reported over 12 months of production, and cabinet assembly time was cut by 40% using standardized pre-assembled DIN-rail terminal strips.
