18 The Electrified Powertrains Library () is currently under development Provides all models necessary in the presented design process An approach to simplify parameter generation Release in end of Q Customer needs can still be considered arkus Andres Td / 17

19 FI Used to couple arbitrary simulation environments that support the open FI standard Eg Functional development and designers could use the same models in different tools Visit arkus Andres Td / 17

20 SF Using parameters in multiple simulation environments Based on native models An approach by odelon to create an open standard data format including tooling in multiple (simulation) environments unit and quantity safety (optionally) graphical editing ndimensional tables Visit arkus Andres Td / 17

21 Conclusion ifferent models are necessary throughout the design process Those models require different parameters Parameter determination is a timeconsuming process The tries to assist throughout the whole process FI and SF can help to reduce redundant work arkus Andres Td / 17
