There is a strongly increasing diffusion of Electric Vehicles (EV) and Plug-in Hybrid Electric Vehicles (PHEV), in order to reduce air pollution in urban environment and to mitigate the global warming issues. Anyway, the achievement of this latter goal strictly depends on the source of primary energy used to generate electrical energy. In the paper, a model for the optimal design and operation of a charging station for EV and PHEV assisted by a PhotoVoltaic (PV) plant is presented. A provisional model for the estimation of the incoming insolation, based on cloudiness prevision, is integrated with a nonlinear constrained optimization algorithm, in order to satisfy the load while minimizing the recourse to electrical grid for battery storage charging. Simulations on different locations and charging loads for various size of PV plant and battery capacity are presented, and the benefits in terms of CO2 reduction discussed.

This paper presents thermodynamic analyses of ten different scenarios for using natural gas to power motor vehicles. Specifically, it presents a comparison between different types of automotive vehicles using fuels made from natural gas feedstock. In comparing the various fuel-vehicle options, a complete well-to-wheel fuel cycle is considered. This approach starts with the well at which the feedstock is first extracted from the ground and ends with the power finally delivered to the wheels of the vehicle. This all-inclusive comparison is essential in order to accurately and fairly compare the transportation options. This study indicates that at the present time hybrid-electric vehicles, particularly those using diesel components, can achieve the highest efficiency among available technologies using natural gas as the primary energy source. Hydrogen spark ignition, all-electric battery-powered, and methanol fuel cell vehicles rank lowest in well-to-wheel efficiency because of their poor fuel production efficiencies.

This article is a feasibility analysis of using the batteries in plug-in hybrid electric vehicles (PHEVs) for peak shaving. The analysis focuses on energy availability of the PHEV fleet as well as the financial savings to the utilities by analyzing different charging scenarios and circuitry. The energy availability and the financial savings are heavily dependent on the location and availability of charging stations. Three charging scenarios are analyzed: charging is possible at any time; cars can only be charged overnight; and charging can be done overnight and twice during the day at the place of work for cars used for commuting. The major findings of the study are that charging only overnight will not provide sufficient energy when needed, but both other charging mechanisms can provide effective peak shaving. The charging anytime would require funding a large number of charging station, but charging overnight and at work could be accomplished with relative minor financial investments. The savings from peak shaving could be used for incentives to offset the extra cost of batteries in plug-in electric vehicles (EVs).
