- In this presentation, we will focus on EV battery thermal runaway propagation simulation. In such a simulation, we model the heat generation due to exothermal reactions during thermal runaway and the subsequent heat transfer of the heat to the cooling system. The exothermal reaction models are calibrated from the accelerating rate calorimetry (ARC) data of a battery cell. The heat transfer is modelled using conjugate heat transfer models in computational fluid dynamics (CFD). Modelling of venting and vented gas reaction is also discussed. Several validated examples will be shown in this presentation including module/pack runaway propagation and the associated venting and vented gas reaction.
