“…In the winter months, the amount of energy produced during the day is sufficient to drive a vehicle from several to several kilometers. However, the monthly amount of produced energy is an important parameter characterizing photovoltaic systems [19]. This is due to the fact that the customer's settlements with the electricity supplier and seller are usually monthly.…”

Energy security with regard to electric vehicles consists in providing an appropriate infrastructure in the form of charging points for electric vehicles, which are able to generate and supply the traction batteries of vehicles with an appropriate amount of electricity. This role is played very well by photovoltaic carports, which are the structures designed to generate electricity and generate a shadow. The vehicle parked under the carport structure is protected against excessive heating. The shade for the parked vehicle is provided by a photovoltaic system mounted on the roof of the carport. Carports are, therefore, an ideal solution for charging electric vehicles. The article analyzes the problem that is related to the selection of peak power of the carport for the electric vehicle (or vehicles) that will be parked under it. An economic and energy analysis is carried out to ensure the fastest and cheapest charging of an electric vehicle. The authors present a study of two cases of carports of different sizes, which were used to charge electric vehicles of various brands with different sizes of traction batteries and different powers of on-board chargers. The results obtained from the conducted research and analysis can be generalized to a larger number of carports and vehicles available on the market.

“…Once the performance metrics of the ESS, MDS, and EMCS are determined, the entire EPS can be modeled as shown in Figure 9. Since each of these three subsystems has two operational states (ie, UP and DOWN), therefore, there will be a total of 2 3 states in the EPS model. In state-1, all three subsystems are operative.…”

“…Again, the transport sector is the second-largest petroleum oil consumer, corresponding to 20% of the global gross primary energy supply. 3 With the rapid diminution of petroleum resources, uncertainty in the oil market, and alarming environmental degradation, the entire automotive world is, therefore, rapidly moving toward electrification. 4 More and more stringent regulations on emissions and fuel consumption have been placed by many countries, promoting the research and development activities on clean and sustainable electric automotive technologies so that the dream of "zero-emission from transportation" becomes a reality.…”

Solar electric vehicle (SEV) is an emerging transport utility, which primarily uses solar energy for its propulsion. It is regarded as an ideal solution for clean and sustainable transportation. This article presents an approach to investigate the reliability and availability of a SEV facilitated with a standby plug-in option. A composite reliability model is developed in Markov framework incorporating the stochastic failure and repair characteristics of all critical electrical systems of the vehicle, namely, power supply system, energy storage system, motor-drive system, controllers, and energy management system. A new probabilistic index is proposed to determine the availability of power generated by the photovoltaic modules mounted on the SEV. This index can be treated as a useful parameter for designing area-specific reliable SEV models. The reliability improvement due to the standby plug-in facility is also examined. The study quantitatively justifies that a SEV with a plug-in facility is much more reliable and effective than a regular plug-in EV. The article also illustrates some novel concepts which can support further research on new reliability design and maintenance of a SEV.List of Symbols and Abbreviations: G, Solar irradiation; G std , Standard solar irradiation; G ref , Reference solar irradiation; T max , Maximum temperature; T min , Minimum temperature; α, Temp. coefficient of PV arrays; P max , PVG capacity; P mup , minimum useful power; r sw , reliability of the changeover switch; R PVG , Reliability of the PVG; A PVG , Availability of the PVG; λ PVS , FR of the PVS; μ PVS , RR of the PVS; λ PVG , FR of the PVG; N i , No. of SEV at i th CS; U i , interruption time per year at i th CS; λ c , FR of the converter system; μ c , RR of the converter system; R CS , Reliability of the CS; A CS , Availability of the CS; λ CS , EFR of the CS; R PSS , Reliability of the power supply system; r SW , Reliability of the change-over switch; Q, truncated matrix; λ 1 , discharging rate of battery; μ 1 , charging rate of battery; λ B , EFR of the battery; μ B , ERR of the battery; A B , Availability of the battery; λ CC , EFR of the charge controller; μ CC , ERR of charge controller; A CC , Availability of charge controller; A ESS , Availability of the ESS; λ ESS , EFR of the ESS; μ ESS ,

“…The e-mobility sector includes a broad range of technological solutions, i.e., from EVs to HEVs and PHEVs [15]. Regardless of that however, environmental performance of vehicles relates to the characteristics of the supply source, and thus, for the e-mobility sector to contribute to the reduction of air pollution, electricity consumed should derive from RES [16]. Given the above, relevant strategic targets focus on two main directions.…”

This study provides a thorough review and analysis of the evolution of the Greek vehicle fleet over the last ~30 years, which is next used for the generation of high granularity fleet projections, the assessment of associated air pollution and the estimation of relevant environmental benefits by 2030. The integrated methodology developed takes also into account vehicle clustering and the Brown’s Double Simple Exponential Smoothing technique that, together with the adoption of COPERT-based emission factors, allow for the estimation of the anticipated emissions in 2030. Expected 2030 emissions levels suggest a reduction across all pollutants compared to 2018, ranging from 3.7% for PM10 to 54.5% for NMVOC (and 46% for CO, 14% for SO2, 28% for NOX and 21% for CO2). We find that Greece is on track with national goals concerning the reduction of air pollution from the transportation sector, which designates the positive contribution anticipated by EVs and new, “greener” vehicles, and sets new challenges for the further improvement of the sector beyond the 2030 outlook.
