Europe & North America: Why Automated PACK Lines Are No Longer Optional

Have you ever run the numbers?

A 10 ppm PACK line—if you are still relying on manual handling, manual welding, and manual inspection—how much extra labor cost are you burning through each year? And that is before factoring in night-shift efficiency drops, turnover, and training overhead.

Problem #1: Low Automation = Structural Cost Leakage

This is not simply a labor shortage issue.

The deeper problem is design philosophy: many production lines were originally planned with “human flexibility” as a contingency—and that contingency quietly became the primary operating model.

Manual cell loading. Manual barcode scanning. Manual welding positioning. Manual data logging.

Each step appears flexible—until you recognize that each step is eroding margin.

Worse still, the more manual touchpoints, the harder it becomes to secure cycle time.

A 10 ppm design frequently stalls at 5–6 ppm on manual lines. You are paying for two lines while receiving the output of one.

The answer is not adding a few isolated machines.

It is a holistic redesign​ across three dimensions:

• Whole-line material flow architecture

• Cycle-time synchronization

• Closed-loop data infrastructure

Roller conveyors with automatic return, independent empty-tray recirculation, and MES-driven real-time data capture are not optional upgrades—they are baseline requirements for sustainable headcount reduction.

Problem #2: Poor PACK Consistency = Yield Loss

Battery modules are not “assembled and done.”

A skewed busbar weld, inadequate pole cleaning, or stacking deviation can scrap an entire pack.

Consistency is difficult because process control points are numerous—and feedback is limited.

Welding power, cleaning effectiveness, press force, CCD inspection criteria—when each station operates as an island, defects are detected only after they have already impacted yield.

The necessary shift is from post-process inspection​ to real-time process control:

• CCD inspection at every critical station

• Vision-guided alignment systems

• Real-time welding parameter monitoring

• Automatic rejection of defective cells

Not for demonstration purposes, but to push yield from approximately 95% toward 99.8%.

Who Can Deliver All of This in a Single Integrated Line?

PENGDAO​ has already demonstrated this capability in production environments.

• Square-cell module PACK line​ – 15 ppm single-line capacity

  From automatic tray loading, OCV full inspection with auto-rejection, pole laser cleaning, and busbar laser welding to post-weld inspection, module testing, and automatic offline—fully unmanned material flow.

  Explosion-proof water tanks and water-based fire suppression are engineered in, not retrofitted.

• Soft-pack PACK line​ – 99.8% yield

  MES + ERP interconnectivity. Data stored locally and uploaded in real time—no “reserved interfaces,” but production-ready integration.

• Cylindrical PACK line​ – Dual-station configuration doubles throughput.

• Containerized ESS integrated line​ – From cabin assembly and lifting to EOL and charge/discharge testing, all within one synchronized flow.

This is not equipment stacking.

This is turnkey solution engineering.

Your line does not need more machines.

It needs a better blueprint.

In the next phase of battery industrialization, competitive advantage may depend less on individual components and more on how efficiently manufacturers integrate processes, data, and quality systems across the entire production chain.

Where do you see the next bottleneck—capacity, integration, or traceability?
