Note: Battery thermal management is critical for performance and longevity. Keeping cells within 20-35°C and <5°C temperature gradient across the pack maximizes life. Liquid cooling is standard for high-performance EV packs.

Reference

Cell Current = Pack Current / Parallel Groups Heat = I² × R × Number of Cells Temp Rise = Heat / (Mass × Specific Heat) Coolant Flow = Heat / (Cp_coolant × ΔT) Optimal battery temp: 20-35°C for Li-ion
