Eco-friendly application of EVs for home-to-work and home-to-education transports

Abstract

Electric vehicles (EVs) today in general are operated with energy from the electric grid. So energy for the EVs is basically available at almost each place on the world. If the energy for the grids however is produced to a big extent from fossil fuels the EVs are not much more eco-friendly than conventional cars. In this paper a field of application is investigated where EVs can be operated very eco-friendly by renewable energy. EVs which are used mainly for home-to-work and home-to-education transports can be charged at the placesof-work respectively at the places of education directly from PVsystems. In a field test with six electric scooters, which were used by students for their travels from their homes to our university, the characteristics of these EVs at a charging station at our university was analyzed. Based on these results the charging of the EVs during typical days was analyzed. The results are showing that the EVs can be charged to a big extent from a very limited PV-system.

“…And yet, the safety systems that such sensors enable could have an important impact, due to the high number of tilting vehicles in the fleets at global level [ 7 , 8 , 9 ]. Current mobility trends are in favor of the usage of tilting vehicles [ 10 , 11 , 12 , 13 , 14 ], partially thanks to their potential for: electrification, recyclability and air-quality improvement [ 15 , 16 , 17 , 18 , 19 , 20 ]. However, tilting vehicles are characterized by a high injury risk for their users, warranting the implementation of new and more effective safety technologies.…”
