Sustainable transportation based on electric vehicle concepts: A brief overview

Energy & Environmental Science (Impact Factor: 20.52). 06/2010; 3(6):689. DOI: 10.1039/C001674H


The energy storage system is of decisive importance for all types of electric vehicles, in contrast to the case of vehicles powered by a conventional fossil fuel or bio-fuel based internal combustion engine. Two major alternatives exist and need to be discussed: on the one hand, there is the possibility of electrical energy storage using batteries, whilst on the other hand there is the storage of energy in chemical form as hydrogen and the application of a fuel cell as energy converter. The advantages and limitations, and also the impact of both options are described. To do so, existing GM concept vehicles and mass production vehicles are presented. Eventually, an outlook is given that addresses cost targets and infrastructure opportunities as well as requirements.

    • "Concerns about emissions coupled with developments in electric vehicle technology have led to the expectation that electric vehicles numbers will rise rapidly over the next few decades. This will result in reductions in emissions and fuel consumption, as well as an increase in energy security by exploiting diverse energy sources [1]. If the plug-in hybrid electric vehicle (PHEV) charging is not managed properly, its extra load may lead to negative impacts, such as voltage limits violation, voltage imbalance, feeders' limits violation, and fuses blowouts [2].

    ABSTRACT: This paper introduces an online coordination approach for plug-in hybrid electric vehicles (PHEVs) charging in smart hybrid AC/DC distribution systems. The goal of the proposed method is to optimally charge the PHEVs in order to maximize the PHEV owners' satisfaction without violating the network constraints. The charging costs, which represent the PHEV owners' satisfaction in this work, are based on real-time pricing. The proposed approach includes consideration of PHEV owners' requirements, PHEV batteries' characteristics, and hybrid distribution system limitations. Moreover, a sliding window concept is introduced to facilitate managing the PHEV charging and the system interlinking converters in real-time. A 38-bus test system has been modified to include DC links and used to validate the developed online charging scheme. The test results clearly demonstrate the effectiveness of the proposed method.

    • "Analysis of zero emission vehicles suggest that fuel cell vehicles are more economically viable for the longer range vehicles whereas for urban transport (~160 km range) batteries are the better choice [1] [2] [3]. Another practical advantage is that it is much faster to refuel hydrogen than it to recharge a similar sized battery. "

    ABSTRACT: We present up-to-date benchmarking methods for testing electrocatalysts for polymer exchange membrane fuel cells (PEMFC), using the rotating disk electrode (RDE) method. We focus on the oxygen reduction reaction (ORR) and the hydrogen oxidation reaction (HOR) in the presence of CO. We have chosen our experimental methods to provide the most optimal compromise between the ease of carrying out the measurements and for ensuring comparability with PEMFC conditions. For the ORR, the effect of temperature, scan rate, Ohmic drop correction and background subtraction on the catalyst activity is investigated, both on a polycrystalline Pt disk and two different commercial Pt/C catalysts. To benchmark the CO tolerance of HOR catalysts, cyclic voltammetry and chronoamperometry are used, on polycrystalline Pt and commercial catalysts consisting of Pt/C and PtRu/C. We recommend the optimal conditions for obtaining a benchmark of ORR activity and the CO tolerance of HOR catalysts.

    ABSTRACT: This paper investigates Stability and maneuverability of Personal Mobility Vehicle (PMV). The purpose of PMV is to provide mobility in city centers. Suspension design concept of PMV is based on accommodating different road scenarios. Non conventional suspension mechanism is adopted to conform stability and handling. Analyses are performed on simple full scale vehicle model to validate the stability of the vehicle. Road scenarios are realized by modeling different terrain profiles. Multi-body analysis techniques are used to obtain the suspension parameters. The vehicle is analyzed on different roads to observe the effect of inertia on system dynamics. The results present the angular velocity, angular acceleration, roll, yaw and pitch variations about center of gravity of the vehicle.
