Sizing of a solar-wind hybrid electric vehicle charging station by using HOMER software

Vehicular emissions make significant contribution to the total ambient airborne pollutants. Global warming and human health concerns are motivating researchers to come out with newer ways of controlling air pollution effectively. On the other hand, there are significant challenges in complying with current and upcoming vehicle emission regulations, which are quite stringent. It is therefore quite important to monitor vehicular emissions closely, which can facilitate adopting effective control measures when necessary, and also in predicting the impact of vehicular emissions on ambient air quality. Traditionally, dynamometers (both engine and chassis) testing has been used extensively to measure and monitor vehicular emissions, and the database generated has been used as input in modeling the traffic-related air quality impact. Even though standard driving cycles are followed in dynamometer tests attempting to closely replicate real-world driving conditions, they may not necessarily represent actual real-world driving conditions and emissions thereof. Therefore, in recent years, significant scientific efforts have been directed to measure and analyze real-world driving emissions (RDE) from vehicles. In this paper, the state-of-the-art techniques and methods for vehicular emissions monitoring under real-world driving conditions are reviewed and discussed in detail. Different vehicle emissions monitoring methods are presented in comparison to dynamometer-based measurements. Several influencing factors which affect on-road and in laboratory measurements are identified and discussed. Potential applications of different emission control strategies are reviewed. Finally, guidelines are formulated for effective vehicular emissions monitoring, and to minimize discrepancies between on-road and laboratory based measurements, in order to have a sustainable road transport system in future.

Real-world automotive emissions: Monitoring methodologies, and control measures

In recent years, it is seen that there has been a huge expansion in the electric vehicles market aiming to reduce the impact of greenhouse gases. The deployment of an optimal and cost-effective electric vehicle charging stations similar to petrol/diesel stations with advanced control algorithms is necessary for the successful implementation. This review paper gives an overview of electric vehicles and various configurations about the design aspects of charging station. The charging stations are categorized on the basis of power utilized with various optimization algorithms, methods and future directions are presented to have an optimal design. And also, the highlights of grid connected combination of renewable energy based and grid connected, off-grid mode are summarized along with the future scope. Incorporation of renewable energy along with storage systems in the charging station can reduce the high load taken from the grid especially at peak times. By providing an overview of these key areas, the review study aims to provide a deep insight to the industry experts and researchers for future developments.
