🚗 Why EV Factories Require Higher Automation Than ICE

EV factories face unique engineering and economic challenges:

✔️ Safety risk of batteries

• Thermal runaway
• Micro-defects
• Contamination

✔️ More complex assembly

• Battery modules
• Cell welding
• Cooling systems

✔️ Higher precision requirements

• Micron-level quality
• Zero contamination tolerance

✔️ High variability of SKUs

• Pack architecture
• Battery chemistries

✔️ Cost pressure

• Batteries are 40–60% of EV cost
• Automation reduces cost aggressively

Result:

EV factories require 3–4x more automation than ICE factories.

🧾 Why Automation ROI Is Higher in EV Factories

Because:

• Scrap cost is extremely high
• Warranty cost is catastrophic
• Safety risk is existential

1 defective battery pack →

• $20,000 loss

1 defective cell →

• $80,000 recall risk

Automation prevents that.
