Abstract
This PhD project aims to advance the modeling of Electrical Propulsion Drive System (EPDS) in Software-Defined Vehicles (SDVs) by leveraging hybrid, multi-domain, and multiscale modeling approaches. The project’s objective is to develop a unified framework that integrates physics-based and data-driven methodologies to enhance the modeling fidelity of EPDS, bridging the gap between component-level and system-level perspectives. This research addresses the need for more comprehensive and computationally efficient models that account for the interactions between electrical, mechanical, electrochemical, and thermodynamic domains.

Description
The PhD candidate will build upon pre-existing models from the prior PRG2532 project and introduce advanced modeling techniques to capture complex phenomena affecting EPDS. Empirical data collected from experimental activities will be utilized to validate these models and improve their predictive accuracy. Additionally, the project will explore the impact of environmental factors, such as temperature, humidity, and terrain, on EPDS performance, integrating these effects into the unified modeling framework. This approach will ensure robust, scalable, and computationally efficient models that support the design and control of SDV EPDS.

- Identify limitations of the existing models and propose strategies for improvement.
- Develop and enhance the models to support component-level (micro) and system-level (macro) perspectives of EPDS in SDVs.
3. Multi-domain modeling and integration
- Incorporate multi-domain modeling techniques that capture the interactions between electrical, mechanical, electrochemical (batteries), and thermodynamic domains.
- Ensure that the models reflect the holistic behavior of EPDS components and subsystems.
- Address cross-domain interactions and their impact on system performance.
4. Development of hybrid modeling approaches
