Stabilizing yield at a new factory, from 12 months to 1 month

Smart factory deployment in North America cuts new-plant yield stabilization time from 1 year to 1 month

• Yield stabilization at a new plant previously took about 1 year
• Five ESS production sites in North America operate as hybrid manufacturing sites producing EV batteries and ESS batteries simultaneously
• Production portfolio must be quickly reshaped to keep pace with a fast-changing market

• Proactive detection of equipment issues through real-time monitoring: Monitors manufacturing equipment status in real time and detects and addresses anomalies in advance
• Maximized productivity with automatic equipment compensation: Automatic parameter compensation without human intervention minimizes process anomalies
• Minimized defect rates through expanded inspection automation: Automatically inspects in-process WIP and final products
• Global standardization: Smart factory solutions proven in Korean plants are copied and pasted to five North American sites, reducing new-plant construction cost (CapEx)

• New-plant yield stabilization time cut from 12 months to 1 month
• Over 90% of process data collected automatically and optimized
• Company-wide average yield surpasses 90% (as of 2025)

These results were achieved through the customer's smart factory innovation initiatives as a whole.
