Modeling and Optimization of the Immersion Evaporative Cooling Lithium‐Ion Battery System

open access: yesModelling and Simulation in Engineering, Volume 2026, Issue 1, 2026.
This paper focuses on the coupling mechanism, performance, and optimization of the immersion evaporative cooling lithium‐ion battery system (IECLBS). A novel dynamic coupling model is established based on the whole heat transfer path. We investigated the coupling mechanism of IECLBS by examining changes in the relevant parameters.
