Abstract：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.
