Battery Modeling Based on the Co

A new battery model by coupling and computational fluid dynamics (CFD) provides the insight of electrical performan temperature distribution of a battery pac potentially suitable for hybrid electric vehicl vehicle (EV) battery modeling because of the high temperature nature of these applications Hybrid vehicle (HEV) and electric vehi future trend for automotive industry. T intensive research in the related areas and has been one of the hottest topics. Models usually divided in two types: 1) physics thermal management simulation 2) electric for system level simulation. Each type has cons. Computational fluid dynamics (CFD been well known for battery pack thermal [2]. The advantage of CFD is that it can a the temperature distribution based on the h boundary conditions, geometry, material pro drawback is that it does not have a good mechanism. Therefore usually over-simplif are used to carry out CFD analysis. On the o models are suitable for system level simula of the most significant advantages of the that they are very fast in terms of simulatio simply because they are lumped parameter parameters are curve fitted from lab me drawback is that it lacks of temperature di makes it impossible for thermal managem therefore propose a new battery model that c model types, circuit model based on CFD one hand the circuit model provides as a he other hand, realistic battery pack geometry temperature distribution as a function of d material, flow rate, etc. The proposed batter simulated between the circuit model and Within each time step of the co-simu generated by the circuit model is sent to source. CFD model then uses the heat from calculate the temperature distribution, a upling of Electrical Circuit and Computation
