This paper faces the technical and economic challenges related to the design of a green recharge area for electric vehicles at the Campus of Palermo, Italy, with the aim of reduce both costs and pollution connected to the charging process. Based on the behaviour of the student population, the electrical load is identified and two possible solutions are evaluated to manage the peak load: an orientation...
In modern transportation, electric bicycles play an increasingly important role e.g. in urban traffic as well as for commuting and recreational activities. Nevertheless, a limiting factor of electric bicycles is the battery capacity. One approach to increase cruise range is regenerative braking, where kinetic energy is recovered during the braking process and used for recharging the battery. In this...
The paper deals with an analysis and experimental tests on a shake flashlight. A shake flashlight has a built-in linear moving-magnet generator with stationary coil. Analytical equations for the induced EMF, current, voltage, electromagnetic force and power have been derived. A special shaker for experimental tests have been designed and fabricated. The results of laboratory tests have been compared...
Limited travelling range is a major concern for fully electric vehicles (FEVs), and enlarging the total driving range is a main research topic of FEVs. Recently, with the development of intelligent transportation systems, traffic information can be available for the vehicle control systems, like terrain profile and velocity and acceleration of preceding vehicles. With such information, energy-efficient...
Nowadays electrical vehicles are in demand and the developments in their field are increasing which is required to improve the performance of the vehicle in terms of single range to cover. An efficient energy storage device is required to improve the performance and the efficiency of an EV. Power requirement of EV is dynamic in nature which requires a high energy and high power density source. A single...
In this paper, three electric vehicle (EV) powertrain simulators are analyzed by combining their modeling methodologies into a single MATLAB script file. A simplified electric vehicle powertrain (SEVP) simulator is compared with two widely used powertrain simulators, ADVISOR and FASTSim. Validation of the simulators is carried out using dynamometer test data on two models of the Nissan LEAF from the...
In this paper we present an easy-to-implement model that allows to determine the potential energy savings of regenerative braking (also: recuperation) for Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs) by exploiting Inter-Vehicle Communication (IVC). The proposed model has been designed to be applied within different braking scenarios: approaching traffic lights, stop-and-go, emergency...
In the present paper the electro-mechanical model of an electric vehicle suitable for battery energy management systems has been presented. In order to verify its accuracy, the comparison between the experimental and simulation results has been carried out. Particularly, the energy battery estimation of a Smart Fortwo electric vehicle has been developed. The electromechanical model describing the...
In this study, implementation of design and simulation programme of a solar energy (photovoltaic panel) supported hybrid electric vehicle was designed, which is considered to be widely used in the 21st century. In the study, DC motor was simulated for a serial hybrid electric vehicle in ICE-generator and photovoltaic panel matlab/simulink environment. Moreover, a .m file was written by calculating...
In this article, the driving performance of two electric vehicles of the latest generation clean powertrain cars is evaluated. The vehicles under test are an electric Peugeot iOn, and an AGV electric version of the Ford Transit Connect. For different torque-speed operating conditions at wheel level, the vehicles are evaluated for their battery to wheel — electrical to mechanical — power conversion...
The mu synthesis robust controllers for hybrid-power EV are developed to ensure the robustness of closed-loop system under the influence of uncertainties, such as the parameter perturbation and the unmodeled dynamics, and to minimize the effect of the disturbances, such as the variation of the battery and ultra capacity voltage, the road state, and the driving mode of vehicle. The simulated and experimental...
Personnel transport vehicles in underground mines are used to transport miners and light equipment within the mine, and are generally driven by diesel engines. To reduce the emission, the eco-friendly electric vehicles (EVs) have been introduced in underground mining. This EV consists of a wheel/axle, final drive, traction motor and energy storage. The model of this vehicle is developed based on the...
In 2010 over fifty advanced vehicle prototypes competed in the $10M Progressive Insurance Automotive X PRIZE competition for 100 MPGe vehicles. Battery electric, hybrid, plug-in hybrid and traditional ICE vehicles were all represented. The competing vehicles were rigorously tested for fuel economy, range, emissions, and other performance characteristics. This paper presents selected data with a view...
With emphasis on a cleaner environment and efficient operation, vehicles today rely more and more heavily on electrical power generation for success. The objective of this project is to propose drive range improvement for electric vehicle using solar energy. First, power consumption modeling based on Proton Savvy using torque analysis to achieve 45mph vehicle top speed when converted to electric vehicle...
This paper describes a new model named electromotive force-impedance to determine the SOC of battery based on the least squares analysis. Determining the state of charge (SOC) of a battery is an essential in fast charging, it can provide parameters in fast charging controlling. More recent models determine the state of charge (SOC) by charging and discharging cycles, this process degrades the chemical...
This paper presents the design and the experimental tests of an ultra-capacitor pack used as an energy storage system in a small hybrid electric vehicle. This design consists in calculating the capacitance and the power of the capacitors, which are necessary to store kinetic energy during deceleration of the vehicle and then to accelerate the vehicle. In a second part, experimental tests are achieved...
