The costs of charging Plug-in Electric Vehicles (PEVs): Within day variation in emissions and electricity prices

Charging Electric Vehicles from Photovoltaic Systems—Statistical Analyses of the Small Photovoltaic Farm Operation

“…on the data obtained from the monitoring system of the photovoltaic system installed in the LSTP, it can be concluded that the PV farm is an important element of covering the energy demand of the tested facility and the additional investment in the carport ensures the use of daily surplus energy to charge the BEV. Such use of the photovoltaic system enables the reduction of the cost of charging BEV [25,27,28,63,66,71] and, as it was noted, in the works [2,24,29,67,69,70,72,76,82], limits emissions from means of transport, which is a very important direction of changes in the transport sector, especially in urban zones. As the data analysis shows, there are statistically significant differences in the amount of energy taken from the grid and the amount of energy supplied to the grid, and the amount produced by photovoltaic panels from the farm and carport.…”

“…Hybrid systems minimize the use of ICE and limit their negative impact on the environment, integrating them with electric motors [63]. The issue of the operation of electric vehicles is now a very important topic raised by many researchers [64][65][66][67][68]; they concern road tests [28,69,70], issues of charging the batteries of these vehicles [64,[71][72][73], and the disposal of lithium-ion batteries from electric vehicles [74]. Changing the powertrain of vehicles causes big changes also for the energy sector, which was noted in the following scientific publications [75,76].…”

Time to rethink energy research

“…The aim of optimizing energy systems has the rhetorical and practical consequence of classifying perfectly ordinary sociotemporal rhythms as 'non-technical barriers' and as obstacles to be overcome. Having assumed that electric vehicles would be charged at night, and having discovered that they are not, further research is then required to understand how appliances fit into diurnal rhythms and to identify ways of persuading people to change their ways 3 . In this example and in many others like it, standardized units of hours, costs and energy fail to capture, or even recognize, the differential valuing of evening activity, or the composition of week-days and week-ends 4,5 .…”

Network tariff design with prosumers and electromobility: Who wins, who loses?

“…This research topic is motivated by the following reasons. Electric vehicles need low-cost power for charging and require a low-carbon energy to have a significant environmental benefit against internal combustion vehicles (Fang et al, 2018). PV generation needs flexible storage to face its variability and intermittency.…”
