论文摘要
对于许多实际应用,描述锂离子袋细胞行为的完全耦合的三维模型在计算上太昂贵了。但是,由于典型小袋细胞设计的远处比率很小,因此通过将问题分解为通行行为的模型和横向行为模型,可以很好地近似此类模型。在本文中,我们将不同的简化结合到通过细胞和横向模型,以开发减少阶袋细胞模型的层次结构。我们在等温和热设置中对这些模型进行了关键的数值比较,并研究了它们在现实驱动周期数据上的性能。最后,考虑到特定研究中的可用计算资源和感兴趣的数量,我们提出了有关模型选择的建议。
For many practical applications, fully coupled three-dimensional models describing the behaviour of lithium-ion pouch cells are too computationally expensive. However, owing to the small aspect ratio of typical pouch cell designs, such models are well approximated by splitting the problem into a model for through-cell behaviour and a model for the transverse behaviour. In this paper, we combine different simplifications to through-cell and transverse models to develop a hierarchy of reduced-order pouch cell models. We give a critical numerical comparison of each of these models in both isothermal and thermal settings, and also study their performance on realistic drive cycle data. Finally, we make recommendations regarding model selection, taking into account the available computational resource and the quantities of interest in a particular study.
