Wireless battery charging for electric bicycles

2017

The contactless solution is increasingly spreading as method of battery charging for Electric Vehicles (EVs). The standard technology of contactless EV battery charging is based on the Inductive Power Transfer (IPT) between two coupled coils, one connected to the electrical grid and the other one connected to the rechargeable battery. The IPT provides benefits in terms of safety and comfort, due to the absence of a plug-in operation. In this paper, an overview on the IPT applied to the battery charging of electric bicycles is provided, with some general considerations on the technical implications. Moreover, a prototype of contactless battery charging for E-bikes is proposed and described.

A Bidirectional IPT system for Electrical Bicycle Contactless Energy Transfer

2019

Contactless Energy Transfer characterized by Inductive Power Transfer (IPT) is a viable solution for Electric Vehicle (EV) battery charging, giving advantages in terms of safety, comfort and automatism of the recharging operation. IPT is a smart option for the Vehicle- To-Grid (V2G) implementation as well: the EV's battery can provide power to other users, if possible and if required, in order to adequately respond to an active demand scenario. IPT shall therefore allow a Bidirectional power flow, so that it can be properly defined as Bidirectional IPT (BIPT). In this paper, a 300 W BIPT system for E-bikes is proposed and experimental results are shown as well. Considering power level and s…

Control subsystem design for wireless power transfer

2014

Recently, the wireless power transfer has been increasingly employed. Particularly for the electric vehicles, the wireless solution is attractive for contactless battery charging, based on the Inductive Power Transfer (IPT). In this paper, a 150W prototype for IPT-based battery charging is presented and design criteria are reported. In addition to the power stage analysis, a proper control strategy is proposed. Simulation and experimental results are shown. The proposed control method aims at regulating the load current against variations in the magnetic coupling, so that the required amount of power can be supplied despite of unexpected decreases in the coupling efficiency.

Experimental test on a Contactless Power Transfer system

2014

Contactless Power Transfer (CPT) is an ever-growing technology in automotive market, due to the significant improvement brought by it to battery charging operation in terms of safety and comfort. CPT is based on inductive coupling between two coils, so that power cords can be avoided for vehicles battery charging and an important contribution towards a smarter mobility can arise. In this paper, a CPT prototype for E-bike is proposed. Magnetic design and power electronics system are described. Experimental results deriving from laboratory tests are presented and power efficiency of the system is addressed.

„Na Ukrainie za owych dobrych czasów” – „Przed laty. Powieść ukraińska” Paulina Święcickiego

2020

The forgotten work and life of Paulin Święcicki (1841–1876), a writer from Kiev region and active in Galicia, represents a rare, authentic example of Polish‑Ukrainian cultural border. His debut work entitled 'Przed laty. Powieść ukraińska' (1865), despite being an artistic failure, is an interesting link between the heritage of the Romantic 'Ukrainian School' and the historical vision of Polish Borderlands in With fire and sword by Henryk Sienkiewicz. The creation of the 17th‑century reality of Ukrainian grasslands (noble, rural and Cossack existence), battle scenes (fights against the Tatars), romantic‑melodramatic plot – these are all adapted to a unique Ukrainian (not Polish‑centred) per…

Water Conflict and Water Management in the Middle East

2004

“Water is Life”: this is often forgotten in countries with abundant water ressources. As a ressource it only gains importance once it is in short supply or once its quality declines. In the case of shortage the battle for water becomes inevitable. At the moment we have up to 200 conflicts of border-crossing water systems in the world. The Middle East is considered to be a typical example of this politically significant problem

United in the Commonwealth. The participation of Lithuanian troops in the Zborów battle in 1649

2018

Abstract In 1648, an uprising broke out in Ukraine that belonged to Poland at the time. The war was not successful for the Polish-Lithuanian Commonwealth. The Cossacks and Tartars, who were helping them during the war, surrounded Zbaraż, about whose defense everyone knew in the country. King Jan Kazimierz decided to set out to rescue the besieged fortress. It was decided that not only Polish troops, but also soldiers of Lithuania would set out for Ukraine. Not only state armies, but also private regiments set out to fight. The article discusses the problem of the reasons for the participation of Lithuanians in the war, which was not only due to the provisions of the union, but also to be in…

Genome structure in Sicilian cattle breeds

2014

Genomic technologies provide background information concerning genome structure in domestic animals. The aim of this work was to investigate the genetic structure and the patterns of linkage disequilibrium (LD) in two Sicilian local cattle breeds, Cinisara and Modicana. Genotypes from animals of Italian Holstein breed were also used to investigate the relationship among breeds. Structure software was used to analyze the genetic structure and assign the individuals to each cluster. The genetic relationship between individuals was estimated by Principal Components Analysis (PCA) of genetic distance. A standard descriptive LD parameter (r2) was obtained between adjacent SNPs and for all pairwi…
