Grid Connection of Shared Electric Vehicles

Thomas Alois Weber, Anjali Devi Vanapilli Nursimulu

The paper examines the decision of whether to connect electric vehicles, for grid-balancing purposes, to an electric power grid, in addition to renting them out on a car-sharing market. Because grid connection tends to degrade a battery over and above its ...

Battery

Pekka Eero Peljo

In a battery system, an electrochemical cell has a first compartment containing a positive electrolyte with an electrode 2 at least partially immersed in the positive electrolyte containing the first redox active material, forming a positive half cell. A s ...

Characteristics and properties of nano-LiCoO2 synthesized by pre-organized single source precursors: Li-ion diffusivity, electrochemistry and biological assessment

Andreas Züttel, Nam Hee Kwon, Mariana Spodaryk

Background: LiCoO2 is one of the most used cathode materials in Li-ion batteries. Its conventional synthesis requires high temperature (>800 degrees C) and long heating time (>24 h) to obtain the micronscale rhombohedral layered high-temperature phase of L ...

Evaluating the need for energy storage to enhance autonomy of neighborhoods

Jean-Louis Scartezzini, Dasaraden Mauree, Amarasinghage Tharindu Dasun Perera, Karni Siraganyan

Energy storage is generally considered as a means to bridge a period between when/where energy is available and when/where it is in demand. Storage plays an important role by providing flexibility to energy systems, increasing the potential to accommodate ...

Effect of charging/discharging on plasticity and fracture in Si anodes for batteries

Seyed Mostafa Khosrownejad

Lithium-ion batteries provide the power for portable electronics and found many other interesting applications. It is desirable to design batteries with high energy density and long cycle life. Silicon is among the highest Li-storing anode materials in bat ...

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 ...

Demo: Efficient Delay and Apodization for on-FPGA 3D Ultrasound

Jean-Philippe Thiran, Giovanni De Micheli, Federico Angiolini, Marcel Arditi, Aya Mohamed Naguib Ahmed Ibrahim, Ahmet Caner Yüzügüler

In medical diagnosis, ultrasound (US) imaging is one of the most common, safe, and powerful techniques. Volumetric (3D) US is potentially very attractive, compared to 2D US, because it might enable telesonography - decoupling the local image acquisition, b ...

Contribution to the Ultra-Fast Charging of Electric Vehicles

Rosa Martel Danoary Tsirinomeny

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 ...

Battery Charger for Electric Vehicles based on a Wireless Power Transmission

Yves Perriard, Paolo Germano

In this paper, the case of a battery charger for electric vehicles based on a wireless power transmission is addressed. The specificity of every stage of the overall system is presented. Based on calculated and measured results, relevant capacitive compens ...
