基于孔隙网络模型的电池热管理系统跨尺度分析

Industry urgently needs multiscale analyses of battery thermal management systems to improve battery safety. Battery packs are modeled here as porous media to optimize the battery thermal management system as a convective heat transfer process in a porous media. The pore-network model is efficient and strongly couples the multiple physical fields. The pore-network model is then used for multiscale analyses of battery thermal management systems. The validated pore-network model can then be used to relate the thermal characteristics of a single battery to the whole battery pack for multi-scale analyses of battery thermal management systems. The pore-network model is based on the flow and heat transfer processes in porous media at different scales and provides a foundation for future multi-scale engineering application.
