Due to environmental issues such as emission of carbon gases, massive energy consumption, depleting natural resources regarding the internal combustion engine (ICE) based vehicles, electric vehicles (EVs) have caught more and more attention. To make EVs feasible and common, the batteries' high cost and performance degradation problems have to be overcome. The degradation of the battery regarding both energy capacity and power capability is highly dependent on conditions of utilization. Inspired by the literature, an electric vehicle model and an energy utilization and battery ageing (both calendar ageing and cycle ageing) model are proposed. Then, these models are validated considering a battery electric vehicle (BEV) in the market. The models are used to optimize the battery size to decrease the total cost of the power train and consumed energy over the battery's lifespan considering Worldwide Harmonized Light Vehicles Test Procedure (WLTP). Finally, the effects of possible future improvements in the technology or alterations in user preferences regarding ageing mechanisms, annual distance, price of electricity, specific cost of the battery pack, specific mass of battery pack, specific cost of electric motor (EM) and inverter, specific mass of EM and inverter, and test procedures on the battery size optimization are investigated.

Several emerging renewable technologies are available to satisfy the current energy demand and to minimize the effect of environmental degradation caused by high consumption of fossil fuels. These technologies are not mature enough to solve this problem but require more time for improving the efficiency, and cost reduction to become the economical alternative of fossil fuels. In this paper Dye-sensitized solar cell (DSSC) has been discussed in detail owing to advancement in the technology. Since each compon...
Assessment of impacts of electric vehicles on low voltage distribution networks in Turkey
Temiz, Armağan; Güven, Ali Nezih; Department of Electrical and Electronics Engineering (2015)
The number of Electric Vehicles (EVs) has reached a substantial value all over the globe due to economic and environmental factors. The increasing penetration of EVs to the distribution grids urges the requirement to investigate the impacts of EVs on the planning and operation of distribution networks. Despite the fact that there are numerous studies discussing the impacts of EVs on distribution grids, a particular study concerning the Turkish distribution networks does not exist. Therefore, this study focu...

Life-cycle analysis (LCA) allows the scientific community to identify the sources of greenhouse gas (GHG) emissions of novel routes to produce renewable fuels. Herein, we integrate LCA into our investigations of a new route to produce drop-in diesel/jet fuel by combining furfural, obtained from the catalytic dehydration of lignocellulosic pentose sugars, with alcohols that can be derived from a variety of bio- or petroleum-based feedstocks. As a key innovation, we developed recyclable transition-metal-free ...
Monte Carlo based control algorithm for economic feasibility of V2G applications
Şahinkaya, Kıvanç; Güven, Ali Nezih; Department of Electrical and Electronics Engineering (2019)
The use of electric vehicles (EVs) has been increasing in recent years due to economic and environmental factors. This rapid development makes it necessary to investigate the effects EVs on the power system planning and system participants. The aim of this study is to determine the optimal operating strategy for a microgrid operator which can function as a prosumer with the contribution of vehicle to grid (V2G) application. The connection time, plug-in time and state of charge (SoC) of EVs are stochastic va...
