Contribution to the Ultra-Fast Charging of Electric Vehicles

It is generally agreed that one of the drawbacks of a conventional vehicle is the inability to always reach the best operating point of the engine and the inability to regenerate the kinetic energy. Meaning, even with the help of the gearbox or automatic t ...

Modeling and Optimal Control of a Redox Flow Battery

Hubert Girault, Dominique Bonvin, Timm Faulwasser, Julien Léo Billeter, Heron Vrubel, Véronique Amstutz, Alberto Battistel, Daniel Wrang

Vanadium Redox Flow Batteries (VRFB) can be used as energy storage device, for example to account for wind or solar power fluctuations. In VRFBs charge is stored in two tanks containing two different vanadium solutions. This approach decouples the storage ...

Escapement-Based Movements as Positioning Mechanisms: Design and Modelling

Romain David Besuchet

This work has been triggered by an industrial project targeting the design of a mechatronic injector for the medical field. Injections are usually performed using a syringe, a quite clumsy tool that transforms the injection task in a positioning one. The q ...

Configurable Modular Multilevel Converter (CMMC) for Flexible EV

Alfred Rufer, Rosa Martel Danoary Tsirinomeny

Today, there is a long-term trend towards bi-directional and flexible charger functions for not only drawing current from the grid but also feeding excess energy back into it. The Configurable Modular Multilevel Converter (CMMC) offers a large flexibility ...

TiO2-SEO block copolymer nanocomposites as solid-state electrolytes for lithium metal batteries

Raffaella Buonsanti

Replacing the liq. electrolyte in lithium batteries by a solid has been a long-standing goal of the battery industry due to the promise of better safety and the potential to produce batteries with higher energy densities. Recently, sym. polystyrene-block-p ...

A Demand-Response Calculus with Perfect Batteries

Jean-Yves Le Boudec, Dan-Cristian Tomozei

We consider an electricity consumer equipped with a perfect battery, who needs to satisfy a non-elastic load, subject to external control signals. The control imposes a time-varying upper-bound on the instantaneous energy consumption (this is called ``Dema ...

Modeling of a vanadium redox flow battery electricity storage system

Christian Blanc

Today, the electricity industries are facing new challenges as the market is being liberalized and deregulated in many countries. Electricity storage is undoubtedly a disruptive technology that will play, in the near future, a major role in the fast develo ...

Replacement and emulation of a lead-acid battery with supercapacitors for a UPS application

Alfred Rufer, Philippe Barrade, Yannick Louvrier

This contribution proposes the study of an ‘On-Line’ UPS, where adaptations have been made to replace the initial batteries with supercapacitors. As the electrical behavior of supercapacitors is different from that one of lead-acid batteries, a power elect ...

A new implantable device for telemetric control of pulmonary blood flow

Nikolaos Stergiopoulos

The main problem encountered in pulmonary artery banding is the difficulty in determining the optimal perimeter of the band, and sometime repeated surgical operations are required to adjust the band perimeter in order to control the pulmonary blood flow. T ...

Investigation and optimisation of hybrid electricity storage systems based on compressed air and supercapacitors

Sylvain Lemofouet-Gatsi

An increasing recourse to renewable energies is one of the key solutions to address the current resource and environmental concerns related to the world energy supply. Because of the distributed and intermittent nature of several of them (Solar, Wind), an ...
