End-of-Line Testing as a Key Efficiency Driver

The demands on battery manufacturing processes are increasing steadily. OEMs and suppliers must meet the highest quality standards while ensuring efficiency and scalability. Faulty battery modules or packs can lead to costly recalls and reputational damage. Yet many testing processes remain inefficient, non-automated, or only partially scalable.

Three core challenges frequently arise on the shop floor:

• Defects are detected only at the end of production, leading to scrap and rework.
  
• Manual or outdated test methods slow down production and raise operating costs.
  
• Lack of flexibility in test systems hampers adaptation to new cell technologies and rising volumes.
  

The solution lies in optimized end-of-line testing that combines automation with scalable, future-ready processes.

h-kon’s Solution: Efficient End-of-Line Testing

Automation as a Driver of Efficiency

h-kon leverages state-of-the-art automation to reduce error rates and streamline throughput. Real-time defect detection improves quality control while cutting test durations.
