Passive vs Active Thermal Management in Energy Storage
1. Two Approaches, Different Assumptions
Passive systems rely on conduction and airflow. Active systems use fans or liquid cooling.
2. Engineering Trade-Offs
Active systems offer better control but higher complexity. Passive systems reduce failure points but limit power density.
3. Matching Thermal Strategy to Power Design
Thermal design must align with PCS power density and operating profile.
IMAX Power engineers select thermal strategies based on real load behavior, not theoretical limits.

4. Conclusion
Thermal management is a system decision, not a component upgrade.
