The popularity of electric vehicles is evidenced by the broad range manufacturers presenting new models plug-in hybrid and battery vehicles. However, success revolution or, rather, rebirth vehicles, hanging a thread, as it lacks involvement large number users, many psychological mechanisms hinder it. What are users’ true feelings about this world vehicles? Are people ready for fifth level autom...

Electric vehicles and hybrid electric vehicles are a suitable alternative for vehicles with hydrocarbons fuels to reduce pollution and fossil resources. The batteries operate as the driving force for these vehicles. One of the most critical parameters of the battery is computing the state of charge (SOC). The best range for SOC of lithium-ion battery is between 20% and 90%, and charging and dis...

Environmental pollution and climate change are critical global challenges of our time. Electric vehicles can tackle these problems by contributing to a sustainable mobility solution and a better environment, in particular in urban areas. Despite their benefits, the diffusion of electric vehicles is still low. This study reports on what information Green Information Systems should provide to the...

Abstract: In this paper, the charging loads of electric vehicles were controlled to avoid their impact on distribution networks. A centralized control algorithm was developed using unbalanced optimal power flow calculations with a time resolution of one minute. The charging loads were optimally reallocated using a central controller based on non-linear programming. Electric vehicles were rechar...

This paper mainly investigates the environmental and economic impacts of worldwide use of electric vehicles. It can be concluded that governments have good reason to promote the use of electric vehicles. First, the global vehicles population is evaluated with the help of grey forecasting model and the amount of oil saving is estimated through approximate calculation. After that, based on the ga...

This paper discusses about the potential need for electric vehicles (EV), charging station (CS) infrastructure and its challenges for the Indian scenario. Battery electric vehicles (BEVs) are promising class of drive trains in the coming years especially in urban regions in order to shift the decentralized exhaust emission in megacities to centralized power plants in rural areas. Up to now the ...

Freight transport has an important impact on urban welfare. It is estimated to be responsible for 25% of CO2 emissions and up to 50% of particles matters generated by the transport sector in cities. Facing that problem, the European Commission set the objective of reaching free CO2 city logistics by 2030 in major urban areas. In order to achieve this goal, electric vehicles could be an importan...

The present paper introduces a new testing process for embedded software development activities in the field of hybrid electric vehicles. The proposed process addresses some deficiencies of the existing testing models in order to improve the performance of HEV embedded software testing activities. The value added is given by the clear split of the test tasks and the level of independence betwee...

Introduction of new technologies such as energy storage systems, electric vehicles, and distributed generation improved the characteristics of networks. On other hand, using these components in distribution systems improves system performances such as power losses. One of effective methods for improving system characteristics is distribution network reconfiguration. In this study, in addition t...
