The proposal entitled MULTI-LEVEL DIGITAL DEVELOPMENT PLATFORM FOR ELECTRIC VEHICLES (MULTILEVEL) represents a step forward to a next-generation tool to be developed by a young team of Technical University of Cluj Napoca (UTCN), fundamental for future cooperation with electric vehicle (EV) OEMs.

The concept challenges the boundaries of scientific limitations in the field of analysis, development and testing tools of electric vehicles (EV) offering new solutions beyond the classical implemented ones. These refer to computer-based simulations, test platforms built to use certain software, unilateral investigation of aspects such as fault tolerance and the concept of power split, that is unilaterally considered for hybrid-EVs. All these new solutions will act as added values implemented as ready for use, library elements in a multi-level powerful digital architecture platform using a genuine graphical representation formalism called Energetic Macroscopic Representation (EMR). The multi-level aspect consists in implementing at least 3-levels of complexity for each of the electric power train assemblies, allowing the user to choose the deepness and the precision of his analysis. Using an integration software (NI VERISTAND) the exported models from several different software (Amesim, Simulink, Maple, etc.) are linked together into one project and simulated on a PXI Real-Time (RT-MiL) processor. Seamless transition from RT-MiL to hardware in the loop (HiL) will be achieved by creating Digital Twins (DT) for all the connections and communications of the actual test bench assemblies. This genuine approach will ensure that a model that is developed in RT-MiL can be tested in actual HiL simply moving the connections of the electronic control unit (ECU) (without any modification) from RT-MiL to the actual test-bench. The experimental validation will prove the operational skills of the digital tool developed by the young research team of UTCN.
