Vehicle Design

The Horizon Europe HighScape project will explore the feasibility of a family of highly efficient power electronics (PE) components and systems for Battery Electric Vehicles (BEVs), including integrated traction inverters, onboard chargers (OBCs), DC-DC converters, and electric drives for auxiliaries and chassis actuators. 

In the work leading to this deliverable, the HighScape component providers and developers, focusing on the adoption of Wide Bandgap (WBG) based PE devices, have been generating the detailed simulation models of the respective components and systems (i.e., traction motor and traction inverter, OBCs, DC-DC converters, drives for Heating, Ventilation, and Air Conditioning (HVAC), and high voltage levelling suspension systems, and thermal systems for PE components/the whole vehicle), with a coverage of their parametrisation involving a wide range of BEV applications targeted in the project. The models enable model-based component and system design at the electrical, electronic, thermal and control levels. The components and systems models have been assembled into a vehicle simulation toolchain, for the rapid assessment of the implications of component design at the vehicle level, including considerations of thermal aspects. Due to the associated computational effort, the component models have been converted into surrogate models, such as Functional Mock-up Units (FMU) before their inclusion in the BEV simulation model. The definition, benefits and limitations of such surrogate models are discussed in the document.
