Recharge stations: A review

2016

Charging equipment for all-Electric Vehicles (EVs) is classified by the rate at which the batteries are charged. Charging times vary based on how depleted the battery is, how much energy it holds, the type of battery, and the type of Electric Vehicle Supply Equipment (EVSE). In this paper, a review of the innovative charging stations is reported.

Designing multi-attribute auctions for engineering services procurement in new product development in the automotive context

2010

Abstract In recent years, use of multi-attribute auctions has been consolidating as a powerful mechanism in procurement settings where multiple drivers affect the transaction outcome. This paper provides a project management approach for multi-attribute auction design for standardized engineering services procurement in the context of new product development in automotive industry. Two variables are taken into account in the bidding process: price and duration of the given engineering activity. From a theoretical viewpoint, we fully determine optimal suppliers’ bidding strategies and expected outcomes, i.e. score/utility, price and duration, for the buyer under both first score sealed bid a…

New approach for harmonic mitigation in single-phase five-level CHBMI with fundamental frequency switching

2017

The main objective of this paper is to study and analyse the voltage output waveform of a multilevel inverter, to suggest a new approach for harmonic mitigation improving the converter performance. These last type of converters represent a new technology in the field of DC/AC electrical energy conversion, presenting advantages respect to the traditional converters. In fact, the multilevel power converters present a low harmonic content and a high voltage level. The paper considers a five-level single-phase cascaded H-bridge inverter and fundamental frequency modulation techniques. The voltage waveform analysis has allowed to identify a working area of the converter where there are lowest va…

Design issues for wind farms grid tied Inverter

2017

In this paper the Authors give indications for the design of a grid tied Voltage Source Inverters (VSI) aimed to optimal use in energy conversion from wind source. In particular, the design of the inverter is more focused on the control system planning, with a particular glance on the grid synchronization problem. After the exposition of general issues concerning renewable energies and associated topics, the case of a grid tied inverter is considered and a methodology of design is sketched starting from the consideration of the DC side and also considering the power device losses, the protection issue against over voltages and over-currents, snubber circuits, heat sinks and, finally the con…

Eletric vehicles impact using renewable energy

2015

In this moment, the principle topics for the modern world are the reduction of environmental pollution and the production of energy from renewable sources (for example photovoltaic system, wind farm, hydroelectric plants, etc.). This particular attention is determined by different reasons, in particular from the Kyoto Protocol, and from different problems as greenhouse effect, acid rain and climate change. The scope of this work is to study, for different years (1997-2013) in Italy, the production of electric energy from renewable and non-renewable. At a later stage, the attention will be on the consumption of the electric energy divided for different sectors. In particular, we study the po…

The strategies for the diffusion of EVs: Focus on Norway and Italy

2017

The goal of this work is to predict e-mobility trends which are essential for understanding the market and the infrastructure development over the next years. Nowadays among the many and different standards and rules there are two charging categories for electric vehicles: High power DC and AC charging modes. It will be interesting to see which technology will prevail in the next few years and if the charging mode option on a given EV affects its sales performance. This study presents the current e-mobility scenario in Norway and Italy, in particular analyzing: EV technical and commercial features, electric vehicle market related national incentive policies, technical and diffusion connecto…

Finite-element performance comparison of IPMSMs with unsymmetrical double-layer windings

2017

This paper presents a comparison of the performances between IPMSMs (Interior Permanent Magnet Synchronous Machine) with a symmetrical and with two different types of unsymmetrical windings. The aim is to demonstrate that the adoption of slightly unsymmetrical windings does not significantly affect the performances of the machines, both in terms of cogging torque and torque/load angle characteristics, providing also the advantage of a higher possibility of choice in terms of slot number/poles ratio. More in particular, an IPMSM model (named IPMSM-1) derived from a commercial geometry equipped with a symmetrical winding is analyzed by using a Finite Element Method (FEM) approach. The simulat…

A framework for defining a sustainability rating system for railway track-beds

2017

Railways perform a significant role in the transportation system and they have relevant environmental, economic and social impacts. They are currently engineered optimizing every singular aspect rather than considering a broader system for improving the sustainability of the overall infrastructure. Thus, it is necessary to promote an effort to define a global sustainability framework for conceiving the design, construction and management of railway infrastructure. The Sustainable Rating System (SRS) proposed in this paper is a tool under development that evaluates different alternatives of railway track-bed structure. Inspired by similar efforts in the field of road engineering such as Gree…
