Note: Active cooling required when ambient exceeds 35C. Liquid cooling is 3-5x more effective than air cooling for large ESS installations.
Reference
Current = C-Rate x Capacity(Wh) / Voltage
I²R Heat = Current² x Internal Resistance
Environmental Heat = dT x Capacity x 0.5 W/kWh/K
Cooling BTU/hr = Watts x 3.412
Airflow CFM = Watts / (1.08 x dT)
