| contents | Battery thermal management system is an indispensable part of the electric vehicles working with Lithium-ion batteries. Accordingly, lithium-ion batteries modeling, battery heat generation, and thermal management are the main focus of researchers and car manufacturers. To fulfill the need of manufacturers in the design process, a faster model than time-consuming Computational Fluid Dynamics models (CFD) is required. Reduced Order Models (ROM) address this requirement to maintain the accuracy of CFD models while could be compiled faster. Linear Time Invariant (LTI) reduced order model has been used in the literature; however, due to the limitation of LTI system, considering the constant flow rate for the cooling fluid, a Linear Parameter Varying system with three scheduling parameters was developed in this study. It is shown that LPV system results could fit accurately to CFD results in conditions that LTI system cannot maintain accuracy. Moreover, it is shown that applying varying water flow rates could result in a smoother temperature profile. |
