As a response to the many challenges faced by OEMs to comply with current and future emission legislations, there will be a diversity of propulsion systems in use, each one with its own specifications:
- IC-engines will still play an important role in the powertrain of electrified / hybrid electric vehicles (HEVs)
- Battery Electric Vehicles (BEVs) will increasingly be used in the urban areas
- Fuel Cell Electrical Vehicles (FCEVs) will be an option for long distance traveling
The powertrain electrification implies an increasing component and system complexity, which requires not only mastering components development, but also their integration into the system. VISION-xEV will develop and demonstrate a generic virtual component and system integration framework for the efficient development of future Battery Electric Vehicle (BEV) and Hybrid Electric Vehicle (HEV) powertrains.
The research work focuses on the following aspects:
- Development of high-fidelity models of electric energy storage components (battery cells of different cell chemistry, innovative super-capacitors), and their integration into a multiphysics simulation framework for integrated electro-thermal, fluid-flow and heat transfer / conduction simulation.
- Development of scalable performance and loss models for electrical / mechanical energy conversion components used in different kinds of electrified / hybrid powertrain (xEV) components and systems.
- Development of high-fidelity and reduced order simulation models for advanced thermal energy conversion (e.g. next generation ICE, engine/turbo-charger integration, innovative after-treatment components) fully accounting for transient/dynamic thermal phenomena.
- Development of a generic modelling and simulation framework for seamless virtual component and system integration to support the efficient development of all kinds of future electrified / hybridized vehicles.
- Demonstration and impact assessment of the VISION-xEV virtual component and system integration framework for the realistic electrified / hybridized powertrain use-cases defined in the project.
