An RF Wireless Power Transfer system to power battery-free devices for asset tracking

Catherine Dehollain, Roberto La Rosa

Internet of Things (IoT) and Wireless Sensor Networks (WSN) infrastructures are becoming more and more available and diffused. One major outcome is the development of new services that help to make everyday life easier and better. One of those to which thi ...

Towards Long-Term Collective Experiments

Francesco Mondada, Michael Bonani, Philippe Rétornaz, Florian Christopher Vaussard, Steven Adriaan Roelofsen, François Rey

It is often challenging to manage the battery supply when dealing with a fleet of mobile robots during long experiments. If one uses classical recharge stations, then agents are immobilized during the whole recharge process. In this study, we present a nov ...

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 ...

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 ...

Principle of Hybrid Energy Storage Systems based on Hydro-pneumatics and Supercapacitors for Distributed Generation and Renewable Energy Sources Support

Alfred Rufer

This paper presents hybrid energy storage systems based on hydro-pneumatics and Supercapacitors with high potentials regarding life cycle and impacts on environment. These so called “Batteries with Oil-hydraulics and Pneumatics (BOP)” systems exploit the h ...

Energy feeding with sequential storage : Properties of the fast energy transfer between supercapacitive tanks

Alfred Rufer, Philippe Barrade

Supercapacitors are new and powerful components for energy storage. Compared with batteries, the amount of energy they can store is low. But, as power sources they have the property to be re-loadable in a few seconds [1][2][3]. In that case, the needed ins ...
