A cell level design and analysis of lithium-ion battery packs
The battery pack was initially exposed to natural convection, but during thermal runaway, the presence of smoke and flames disrupted this condition. This change in airflow likely affected the boundary conditions on the left and right sides of the pack. While forced convection would be more accurate during thermal runaway, the model simplified this by assuming natural …
