Abstract: The widespread presence of uncontrolled electric vehicles causes overloading of distribution network equipment. One of these equipments is distribution transformer, which should pay attention to overloading and reducing lifetime of this equipment due to charging of electric vehicles. First, strategies have been proposed to investigate the effect of electric vehicle penetration level a...
Many studies have been done on hybrid vehicles in the past few years. The full hybrid vehicles need a large number of batteries creating up to 300 (V) to meet the required voltage of electric motor. The size and weight of the batteries cause some problems. This research investigates the mild hybrid vehicle. This vehicle includes a small electric motor and a high power internal combustion engine...
From the point of view of network operation, the lack of proper management of electric vehicles in the network can change the load profile of the network and causes numerous peaks and valleys in it, which is not appropriate from the perspective of network operators. In this paper, an intelligent charging strategy in which according to the information recorded by drivers such as the length of th...
Current electric vehicles (EV) and fuel cell vehicles (FCEV) suffer from several limitations that prevent them from becoming a true commercial success. When available, kilowatt class LENR generators combined with modern thermoelectric conversion technology could enable designing new type of automobiles, being low cost, maintenance free and zero emission at the same time. In the present talk, we...
The project E-Vectoorc (Electric Vehicle Control of Individual Wheel Torque for Onand Off-Road Conditions) targets the development of an integrated controller for vehicle dynamics and energy efficiency for fully electric vehicles with one to four electric motors. The project is funded within the 7th European Union Framework Programme and unites two OEMs (Jaguar Land Rover, Skoda Auto), one supp...
One of the most critical issues for the environment today is pollution generated by hydrocarbon combustion, which is one of the main sources of power for transportation. Hybrid electric vehicles (HEV) and full electric vehicles (EV) are rapidly advancing as alternative power trains for green transportation. The vehicles’ electrification not only involves the traction parts, but it is also gener...
In recent years there has been rapid development in the electric vehicles sector: technology performance is improving, costs are decreasing and more electric car models are becoming available on the market. Globally, governments, car manufacturers, capital markets and customers have moved decisively in favour of electric vehicles, and there is a clear international consensus that the future of ...
This addendum adds to the analysis of ‘An innovation and policy agenda for commercially competitive plug-in hybrid electric vehicles’ (D M Lemoine et al 2008 Environ. Res. Lett. 3 014003) to the case of all-electric vehicles (EVs). We pay particular attention to grid impacts, break-even battery costs, and the three ways in which EVs could dramatically change the results we obtained for plug-in ...
This article introduces a specific and simple model for electric vehicles suitable for load flow studies. The electric vehicles demand system is modeled as a PQ bus with stochastic characteristics based on the concept of the queuing theory. All appropriate variables of stochastic PQ buses are given with closed formulas as a function of charging time. A specific manufacturer model of electric ve...
Electric vehicle has received more and more extensive attention, which is one of the major development directions of motor vehicles using new energy sources. Electric vehicles are development promising green transports, and important means to solve energy and environmental problems. The construction of charging infrastructure is an important prerequisite for the advancement of electric vehicles...
