1ENGLISH TERM PAPER Electric Vehicles Electric vehicle is considered as essential means for coping with the increasing environmental issues within transport sector. Governments all over the world have targeted for increasing electric vehicles’ number. There is need to increase renewable energy’s share in electricity generation for making electric vehicles much more environmentally friendly (Feng et al. 255). Electric vehicles are one of possible solutions to help in successfully climate change. City transportation’s electrification as well as renewable energy resource’s use within transport system is the leading trends of sustainable transportation (Ajanovic et al. 422). There is promotion of electric vehicles as the future transportation having potential benefits of environment to promote urban transportation. Light weight battery electric vehicles (BEVs) are most famous models which catch global attention as well as have enormous integration possibilities within systems of transportation (Jursova et al. 38). Electric vehicles’ simple definition will be automobile where electric motor will replace gasoline engine. Electric vehicles are created by use of similar chassis as in gasoline vehicles. It is quite tough in distinguishing electric vehicle from gasoline vehicle. Only thing which indicates vehicle to be electric vehicle is level of low noise which the vehicle produces as there is limit for creating sound (Coffman et al. 83). Power that is transmitted into motor comes from rechargeable batteries’ array as well as is regulated through controller. Electric vehicle’s operating principle is dependent on the DC controllers which take the power from battery (Plötz et al. 35). Electric vehicles modulate this in manner which motor receives quantity of power which the electric vehicle requires. DC controller is throttle signal for indicating power level which can be sent to motor. Electric vehicles are promising enough for increasing energy efficiency however do not have capability to reduce greenhouse gases (Liao et al. 267).
2ENGLISH TERM PAPER Biggest change which is brought by the eco-friendly vehicles was noise reduction as well as reduction of air pollution through reducing carbon dioxide along with other harmful emissions (Feng et al. 252). Eco-friendly vehicles’ new concept is good start to healthier environment, however more attention is needed also for process of recycling as electrical batteries’ benefits are essential always, and however recycling process’s negative effect is skipped often (Liao et al. 260). First step to develop well-defined end for battery’s life strategies is necessity for knowing their composition to select correct process for recycling. Through recycling them, little quantity of energy could be recovered (Tobollik et al. 354). Generalized process of recycling for the batteries uses energy and water for separating wastes form the viable substances. Electric vehicle is recognized as a key technology within automotive industry, contributing to the sustainable development by greenhouse gas’ lower emissions, less pollution of air as well as new opportunities of job with positive social impact (Gabsalikhova et al. 672). In future, increase in nuclear energy’s generation as well as energy from the alternative sources like, biomass waste, solar power and water power is expected. Electricity could not be generated from oil (Ajanovic et al. 421). Electric vehicles will introduce relation among water footprint and carbon footprint. Electric cars are turning to be essential element in automotive industry’s development strategy. One of priorities to develop transportation system is dealing with decrement environment’s negative impact due to green fuels’ use, which include natural gas. Green fuel is biofuel which is distilled from animals and plants materials (Coffman et al. 81). Consumer preferences’ global trends will affect market’s structure of automotive vehicle within 2025. Need of products which have new properties will develop inevitably. The vehicles will be different fuel vehicles, which includes electric vehicles along with smart vehicles. Smart vehicles are
3ENGLISH TERM PAPER autonomous vehicles (Gabsalikhova et al. 672). Obstacles and capabilities either prevent or stimulate vehicles’ development. The engines deal with finite hydrocarbon reserves that are available, constant growth in prices of every kinds of fuel and environmental degradation (Huang et al. 106465). Maximum global vehicle manufacturers see resolution of the issues for application having technologies to save energy and transition for electric transmission by using power units that are environmentally friendly. Due to urgent need in reducing emissions of greenhouse gases as well air pollution, there is rapid increment in interest of mobility’ electrification (Plötz et al. 38). However, despite implementation of several supporting policies in various countries, quantity of electricity that is used for transportation sector is negligible still. In meantime, there is recognition of electric vehicles by several governments as the technology that could contribute in reductions of emissions in sector of transportation (Jursova et al. 38). Due to implementation of various supporting policies in number of countries all over the world, quantity of electric vehicles is increasing continuously with almost 3 million electric vehicles. However, electric vehicles total number is still quite low when compared with total stock of vehicles (Tobollik et al. 354). Main reasons for electric vehicles’ slow penetration are higher prices for purchases, longer time for charging, charging infrastructure and shorter range for driving. Emissions taking place while manufacturing of electric vehicles are not same for ICE vehicles. Biggest difference is the fact that there is no internal combustion engine or fuel tank for battery electric vehicles, instead have electric drive motor, systems for regenerative braking, power control electronics and battery pack (Ajanovic et al. 429). Major issue as well as biggest source for uncertainty for electric vehicles’ future assessment is battery. Size and type of battery that are used for cars have quite high impact over materials used for manufacturing the vehicles

4ENGLISH TERM PAPER as well as manufacturing emissions (Petrauskienė et al. 119042). Electric vehicles are promoted widely as technology that is environmentally friendly and several governments provides several incentives with goal for increasing electric vehicle’s use and reduce finally air pollutions as well as emissions of greenhouse gases from sector of transport (Liao et al. 256). However, electric vehicles’ total emissions are dependent from emissions that are caused during production as well as use of vehicle. Physical limitations for power exchange among few countries could be modelled through setting restriction of maximum quantity of electricity that could be exchanged among model nodes during any time (Plötz, et al. 35). Extension of transmission losses and capabilities of inter connector are considered within exogenous data. Optimization model’s major decision variables are existing capacities’ production level, investment within new capacities as well as energy exchange flows among market areas (Coffman et al. 83). The program to reduce emissions of gas within transport promotes infrastructure of vehicles with respect to clean energy, plug-in hybrid electric and electric vehicles’ charging stations (Tobollik et al. 353). However, accelerating existing refurbishment as well as deployment of infrastructure of new energy is crucial for achieving objectives of energy as well as climate policy for reducing emissions of greenhouse gases (Feng et al. 261). Fuel mix of future transport will be including characteristics: reducing emissions of greenhouse gases, reducing energy dependence upon third countries as possible, keeping consistency in costs and diversifying sources of energy. It is indicated by the global trends that measures should be taken for ensuring transition of environmentally friendly kinds of transport. Currently, at same time, diel and petrol fuel remain to be dominant kinds of motor fuel (Gabsalikhovaet al. 672). Major trends for
5ENGLISH TERM PAPER developing electric vehicles might be associated to development of charging stations as well as batteries of high capacity (Liao et al. 260). Resource management of greenhouse gas as well as water is now essential parts of the sustainable transport. Public tends in judging electric vehicles’ environmental benefits with the energy consumption as well as emissions while using. However, mobility’s whole effects on environment are based on entire lifetime of electric vehicles (Jursova et al. 38). Additionally, considerable role is played by battery recycling for reduction of emissions of greenhouse gases. Concerns about environment as well as fossil fuel’s rising costs are the driving automakers for designing and building energy efficient and cleaner vehicles, represented by electric vehicles (Tobollik et al. 356). Major drawback is energy source. Hence, electric vehicles will not be able in helping successfully fight the change of climate by reducing emission of greenhouse gases.
