Configurable Modular Multilevel Converter (CMMC) for a universal and flexible integrated charging system

Alfred Rufer, Rosa Martel Danoary Tsirinomeny

Electric Vehicle (EV) owners are confronted by the limited compatibility of available charging infrastructures. Therefore, this paper is focused on presenting a Configurable Modular Multilevel Converter (CMMC) for a universal and flexible integrated chargi ...

Atomistic Modeling of Effect of Mg on Oxygen Vacancy Diffusion in alpha-Alumina

Paul Bowen, Ulrich Aschauer, Abhishek Tewari

Oxygen diffusion plays an important role in grain growth and densification during the sintering of alumina ceramics and governs high-temperature processes such as creep. The atomistic mechanism for oxygen diffusion in alumina is, however, still debated; at ...

Advanced Automotive System based on Modular Multilevel Converter

Rosa Martel Danoary Tsirinomeny

Battery packs in recent electric vehicles (EVs) have high energy and high power densities which exerts a strong thermal stress upon them. This means that the individual battery cells are more prone to decline away and eventually fail early because of an ex ...

Ultrafast Charging Compatibility of Electric Vehicles

Alfred Rufer, Rosa Martel Danoary Tsirinomeny, Hardi Hõimoja

To increase the appeal of electric vehicles, the trend is to shorten the charging time and to lengthen the autonomy. The new ultrafast charge compatible battery on lithium-titanate gives the best compromise between high power and energy densities. The main ...

Modular Converter Architecture for Medium Voltage Ultra Fast EV Charging Stations: Global System Considerations

Alfred Rufer, Michail Vasiladiotis, Antoine Béguin

Electric Vehicles (EVs) are expected to contribute significantly to the reduction of CO2 emissions and other types of pollution within the next years. However, the concept of their ultra fast charging still poses demanding requirements, both in terms of th ...

Toward Ultrafast Charging of Electric Vehicles

Alfred Rufer, Hans Björn Püttgen, Massimiliano Capezzali, Michail Vasiladiotis, Hardi Hõimoja, Stefano Grioni

The paper is devoted to the problems arising from the ultrafast (≤ 10 min) charging of an electric vehicle (EV). An ultrafast charging station (UFCS) must provide high power output with minimal influence on the electricity transmission system, which can on ...

Integrated Solid Oxide Fuel Cell

Emanuele Facchinetti

Distributed power generation and cogeneration of heat and power is an attractive way toward a more rational conversion of fossil and bio fuels. Solid oxide fuel cell (SOFC) – gas turbine (GT) hybrid systems are emerging as the most promising candidates ena ...

Driving an electric vehicle. A sociological analysis on pioneer users

Christophe Jemelin, Nicolas Louvet

In most of the western countries, car is the prevalent means of transport for local mobility. At the same time, sensitivity to environmental issues is increasing, correlated to the consciousness that carbon dioxide emissions have to be reduced. In regard t ...

CdTe surfaces: Characterizing dynamical processes with first-principles metadynamics

Wanda Andreoni, Fabio Pietrucci, Guido Gerra

We study dynamical processes at CdTe surfaces using ab initio metadynamics simulations. The c(2X2) to (2X1) transition of the Te-terminated (001) surface is found to involve a "c(2X2) + (2X1)" intermediate, consistent with experiment, and crossing of simil ...

Design methodology of an electric vehicle hybrid energy storage unit for improved energy efficiency

Philippe Barrade

This work proposes a design methodology that allows designing the energy storage unit of an electric vehicle in order to minimize the required energy and the resulting losses. A simple analytical model of the vehicle losses is derived. Driving conditions a ...
