Degradation mechanism of batteries has to be carefully studied when considering their utilization in electrical power systems. This paper presents the results of an extensive experimental campaign, through which three different lithium–iron–phosphate (LFP) cells were subjected to different electrical cycling stresses. The purpose of the campaign was to evaluate the cells’ aging, as well as to try to find parameters on the cell behavior before its end of life, able to act as state-of-life (SOL) (or aging) indicators. The considered stress consists of the cyclic repetition of fixed-duration discharge steps, followed by full charge phases. The three cells under study were subjected to the very same stress pattern but with three different discharge and charge power levels: low, medium, and high. The results showed that the end-of-discharge voltage and the cell internal resistance can be used as good SOL indicators. However, both are significant functions of the cell conditions, such as the state of charge (SOC) and the cell temperature.

In the past years, forklift manufacturers have started to hybridise their products under the worldwide interest toward electrification. This is generally made starting from existing standard products, and converting them into hybrid versions, rather than start from scratch and designing fully new vehicles. This approach involves several gaps from the inaccurate evaluation of the powertrain architecture and relative energy management strategy, up to a rough sizing of components. Therefore, this study suggests a structured methodology to follow, aimed to properly design hybrid forklift trucks. The first step is the analysis of the conventional working machine to hybridise, identifying one set of duty cycles. Then, the design of the new powertrain architecture, with a proper energy management strategy, and the definition of a numerical simulation model realised through a multiphysics object-oriented software package, to properly size the new powertrain components, and to verify energy and power flows. Finally, it is also presented a brief-cost–benefit analysis, as last verification of the proposed methodology, to verify the cost-effectiveness to bring the new products to the market. Results have shown the general feasibility of the operation since the significant reduction in fuel consumption is combined with sustainable costs of the new electrified components.

The most common system for railway high-speed lines electric supply and the somehow de-facto standard is a special AC industrial frequency system called 2 × 25 kV system. Although several studies exist showing the performance of this system in frequency and time domains, there is a lack of studies analysing how geometric parameters influence the system behaviour, mainly in terms of conductor currents. This study first introduces a simple analytic model able to explain the fundamental feats of 2 × 25 kV systems, then evaluates the effects of critical electrical and geometrical parameters on this behaviour based on mathematical relationships and numerical computations. This simple model allows understanding the main reasons why this system is able to transmit power as a 50 kV system, while trains experience just 25 kV.

MC’s PlotXY, in the following just called PlotXY, is a free piece of software able to make line plots and bar charts from data deriving from measuring devices or simulation programs using several formats. It allows to visualize and post-process these data without the need to have on the target computer the original software that generated it. It was written from the ground-up having researchers and scientists in mind, and therefore is optimized for speed, clarity, soundness. Its special characteristic distinguishing it from the large base of existing plotting software is its flexibility: using this small piece of software, the user can do plotting and post-processing activities on the results obtained from other sources (simulation software or measuring devices) without having these sources installed on the computer where post-processing is made. Moreover, it allows reading file formats rarely available on non-specific software, such as ATP, Comtrade, LabView formats. Although the support of some of these formats is not complete, being the software open-source, anyone can contribute to expanding them, operating on just a single cpp file. It is developed using the Qt platform, which allows good GUI design, and already available for Windows, Macintosh, and Linux systems. This paper describes the software characteristics and some programming techniques used to develop it.

Today, there is a great availability of software to plot simulated or measured data either commercial or free, possibly open source. The author has created one of them, which has the specificity of being compact, compatible with several input formats, and freely distributed, available for Windows, Macintosh, and Unix. It has also the ability to postprocess simulated and measured data. This paper shows some of the choices that have been made to produce this tool, gives hints on their implementation, and shows which special characteristics were searched for, which not always are available on larger tools or tools built into simulation or measuring software.

Today’s AC railway feeding systems are composed by several conductors with various connections to each other. The return current is shared between rails, ground wires connected to rails, ground; current flows to ground are determined by rail-to-ground distributed conductance. This paper gives formulas to deal with all these complexities, both for power quality and power frequency studies, integrating and combining previous studies which cover only part of them. Especially new in this paper is a technique to include in the computation currents dispersed into soil through ballast. It also illustrates a way to implement easily all the proposed formulas using a specific, open and flexible simulation language, the Modelica language. An application of the proposed formulas and related simplifications is illustrated.
