An innovative heterogeneous modeling approach to build a cooling system for battery thermal management with common fluid properties involving FMI terminals

Abstract

In this paper, a new modeling approach combining nativeSimcenter Amesim submodels and Modelica submodels ispresented. FMI terminals are used to enable the physicalconnection of fluids between Simcenter Amesim and Modelica.The innovation lies in the fluid properties that arecomputed in the causal and acausal worlds using the sametechnology. The architecture of a new Modelica AmeTpfMedialibrary developed to ensure continuity of fluid propertiesis presented, along with its accuracy and performance.Using this new approach, a demonstrator of a closed-loopheterogeneous cooling system for battery thermal managementis built, opening the door to a new way of thinking complexmulti-physics systems.
