Methodology development for analytical modeling of hybrid vehicle’s electrical components: Energy performance optimization

The hybrid electric vehicle (HEV) is a complex system consisting of several energy sources. Depending on their configuration typically combining an internal combustion engine, electrical machinery and a storage system, significant benefits in terms of energy consumption as well as other  features can be achieved as compared to a conventional vehicle. In order to achieve this goal, optimization is required at different levels. For a given use, the energy performance of the HEV  mainly depends on three highly interdependent aspects:
-    The topology : series, parallel ...

Optimization of a distributed energy storage system for the improvement of electric grid flexibility

The ever increasing market penetration of electrified vehicles, the diffusion of intermittent renewable energy sources, together with the growing public interest in environmental issues, are acting as a catalyst for research on smart-grid energy management. It is nowadays widely acknowledged that the growing number of electrified vehicles can cause very high peak electricity demand, which needs to be properly addressed and managed in order to avoid electricity demand/supply unbalance and system breakdown.

High frequency modeling of synchronous magnet machines, Application to the early detection of inter-turn fault and demagnetization fault

Powertrain electrification in the transportation field is currently a strong trend. Permanent magnet synchronous machines (PMSM) are commonly used in this type of application because of their compact design and their high energy efficiency. In this context, the proposed PhD thesis concerns the detection of defects in PMSM right from their first appearance phase in order to plan maintenance time, to reduce repair cost and to increase machine availability.
