19MWh Precision ESS | ±0.5% Voltage Stability for Smelters
Project ID: 05
Location: Gongyi, Henan, China
ESS Capacity: 19 MWh
Application: Critical Process Power Backup for Aluminum Production
Project Brief:
Deploys ultra-precise liquid-cooled ESS (cluster ΔT<3°C) to secure continuous power for energy-intensive smelting processes.
Key Challenges
• Extreme Thermal Sensitivity: Aluminum electrolysis requires voltage stability (±0.5%)
• High Ambient Heat: Plant temperatures up to 45°C challenge thermal uniformity
Technical Design (Solution Highlights)
Cluster-Optimized Thermal Management
▶ Per-Cluster Liquid Cooling: Independent coolant loops for each battery cluster
▶ ΔT <3°C Guarantee: AI-adjusted flow rates maintain unprecedented consistency
Tiered Safety Architecture
• Cluster-Isolated Fire Suppression: Vents + inert gas injection per unit (not whole system)
• 3-Stage Cascade Protection:
Pressure release at 150kPa
Coolant flooding if ΔT >5°C
Grid isolation in 200ms if thermal runaway is detected
Outcomes
✔ 100% Power Stability for 6,000kVA smelting load
✔ Zero Production Interruptions despite 3 grid failures
✔ ↑18% Battery Longevity vs. air-cooled systems
✔ CNY 2.3M/year Saved by avoiding voltage sags
