  7. Abstract:
  8. Battery thermal management system is the indispensable part of the electric vehicles working with Lithium-ion batteries. Accordingly, Lithium-ion batteries modelling, battery heat generation and thermal management is the main focus of researchers and car manufacturers. While Computational Fluid Dynamics (CFD) has been used quite successfully for battery thermal management, CFD models can be too large and too slow for assembling in battery pack level models or vehicle models. In this research a much smaller reduced order model is developed, which is in the core is based on CFD models. Thus, without losing the accuracy, this model can be implemented in the vehicle model. The developed model has the ability to provide the thermal system answer with arbitrary flow rate, water inlet temperature, and heat generation in few seconds. This model can be coupled to battery heat generation model, which is itself a model based on experimental data, to simulate the battery response in real situations. The comparison between this model and CFD model is presented, and parameter study on the efficiency of thermal management system in cell, 10-cell module, and vehicle level is done
