Work context
The postdoctoral scholarship is granted by the OpenLab PSA, in collaboration among the laboratories GeePs and L2S of CentraleSupélec, and SATIE, Paris-Saclay University (Paris, France), which focus on the development of next generation electric vehicles.
Missions
Due to the increasing interest on electric vehicles, nowadays several contributions on management of the on-board energy storage systems are available in the current literature. For example, different electrical systems composed by several storage devices and power sources have been investigated to the purpose to increase the vehicle’s autonomy. Here, the target of the postdoctoral scholar will be to assess the overall performance of these hybrid storage systems, taking into account both the performance of the storage devices and the sources and the possible energy management strategies.
Activities
A detailed literature analysis is expected to provide a list of electric architectures matching the desired performance criteria for a hybrid electric vehicle with two energy sources. Then, a proposition of one or more dedicated architectures is expected; for each of them, technical aspects characterizing pros and cons are needed. The goal is to find an architecture that is competitive in terms of reliability, energy efficiency and cost. In particular, main target will be the architecture that minimizes the number of components necessary for the voltage / current adaptation between the various sources and the on-board loads.
The post-doctoral scholar is expected to suggest the utilization of several combinations of energy sources. For each combination, motivations on the need of the converters connected to the several storage devices associated to the electrical architecture have to be described. This analysis should also take into account the possibility to let the DC bus voltage vary in a certain region of operation, according to the characteristics of the storage device that will set the bus voltage and the loads. A pros and cons analysis on the possibility to impose a voltage value to the DC bus is needed, in terms of increase of component sizing and loss of performance. The formalization of a multi-level control strategy is expected for each targeted architecture. It has to consider both energy management of the power sources and power stability issues with respect to voltages and currents.
Desired candidate profile
• PhD in electrical engineering, with specialization in energy systems or other related field, and good expertise in control systems
• Strong experience in the field of electric vehicles with several energy sources, and control theory
• Experience in publishing high quality research papers
• Proficient English
• Strong experience in the development of architectures for electric vehicles
