Understanding how immersion cooling affects long-term battery degradation

Battery degradation is a complex phenomenon. The usage of special strategies like immersion cooling can optimize battery degradation and increase safety. However, immersion cooling introduces greater system complexity, which can increase costs and introduce additional failure modes. This use case explores long-term battery degradation, potential safety risks and cell-to-cell variability over the pack lifetime.

Approach

Comparing immersion and conventional cooling under real-world conditions and investigating cell-to-cell variation before assembly and at end of life.

Results

Although cells age more uniformly under an immersion cooling system, outliers appear during the pack lifetime. Noninvasive and invasive techniques can help identify the reason for this behavior.

 

Understanding the benefits of immersion cooling strategies

Battery degradation is a complex task that requires multi-disciplinary knowledge.

When it comes to battery pack and uniform temperature distribution and homogenous degradation, understanding different interconnected factors require extensive expertise including battery-working principles and electrochemistry, usage of invasive and noninvasive techniques, modeling and simulation, and testing.
