The European Union is aiming at increasing the market share of biofuels in order to improve the security ofsupply of transport fuel and to reduce CO2 emissions. The target is to reach a 10% of fuels from renewablesources on energy basis in the transport sector by 2020 and biofuels represent one of the most importantoptions. Bioethanol and biodiesel represent the only biofuels cu...

This paper deals with the real-time energy management strategies for a hybrid energy storage system (HESS), including a battery and a supercapacitor (SC), for an electric city bus. The most attractive advantage deriving from HESSs is the possibility of reducing the battery current stress to extend its lifetime. To quantitatively compare the effects of different control strategies on reducing ba...

Bu çalışma, güç paylaşımlı bir hibrit elektrikli araç (HEA) için, Monte Carlo (MC) algoritmasına dayalı olarak tahmin edilen sürüş çevrimi hızlarını kullanan öngörülü eşdeğer tüketim minimizasyonu stratejisi (Ö-ETMS) önermektedir. Önerilen Ö-ETMS, enerji kaynakları arasındaki dağılımını en iyi şekilde belirlemek için MC algoritması tarafından hız profillerinden tam yararlanmaktadır. çalışmada; ...

Energy management strategy is developed by considering the random and air conditioning load fluctuation, which greatly affected torque control of electric motor in vehicle. Firstly, vehicle power consumption model established, based on influencing factors energy consumption: load. Therefore, driving conditions with characteristics representing actual are constructed. According to clustered char...

Abstract In the past, type approval of road vehicles with regard to production pollutants was carried out exclusively in form laboratory tests. Laboratory tests determined course vehicle’s driving cycle and methodology for quantifying depending on distance passed. The revision EU legislation 2016 brought changes field approval, particular a change an additional test real drive emission. paper d...

A multi-mode power-split (MMPS) hybrid electric vehicle (HEV) has two planetary gearsets and clutches/grounds which results in several operation modes with enhanced electric drive capability and better fuel economy. Basically, the battery storage system is involved in different operation modes to satisfy the power demand and minimize the fuel consumption, whereas the complicated operation modes...

This paper presents a fuzzy logic controller (FLC) based energy management strategy (EMS), combined with power filtering for pure electric vehicle. The electrical supply is provided by hybrid storage system (HESS), including Li-Ion battery and supercapacitors (SCs), adopting fully active parallel topology. vehicle model was organized constructed using the energetic macroscopic representation (E...

This paper presents an energy management system (EMS) based on fuzzy logic control (FLC) strategy combined with power filtering. is developed for Electric Vehicle (EV) hybrid storage systems (HESS). The proposed and aims to ensure efficient split guaranteeing that battery supercapacitors (SC) provide the continuous transient-power, respectively, adopting a pure electric vehicle fully-active par...

Vehicle driving cycles have complex characteristics, but there are few publicly reported methods for their quantitative characterization. This paper innovatively investigates multifractal characteristics using the fractal theory to characterize properties, laying foundation applications such as vehicle cycle feature identification, energy management strategies (EMS), and so on. To explore scale...

In the present study, the effects of different biodiesel blends on the unregulated emissions of a Euro 4 compliant passenger car were examined. Two fresh and two oxidized biodiesel fuels of different source materials were blended with an ultra low sulphur automotive diesel fuel at proportions of 10, 20, and 30% v/v. Emission measurements were conducted on a chassis dynamometer with a constant v...
