#### Abstract

Functional Mock-up Units (FMU) refer to tool-independent models exported from their original simulation tools. They enable component manufacturers and system integrators to exchange models across entire production chains to validate solutions virtually. However, since system equations cannot be accessed or modified in an FMU, numerical challenges can arise, especially when coupling similar energy storages. In this paper, therefore, Differential Algebraic Systems of Equations are analyzed for their suitability for FMU couplings. It is shown how such systems of equations can be described in a general way and how suitable coupling constraints for FMUs are chosen. Subsequently, three solution approaches are presented and analyzed for their feasibility with FMUs.
