Development of Power train in Electric Vehicles
IRJET, 2022
Electric vehicles (EV) are the future of not just transportation, but also of our world. But could there ever be a more severe sort of congestion for electric vehicles? These automobiles are connected to a low voltage charging station. These automobiles don't produce any pollutants. But what if you own an electric car that is charged by solar power or household electricity? What if you could power your house and garage with this charge? You won't have to worry about the effects of gasoline exporters anymore. Drivers of electric cars must thus plan for lengthy journeys and camping. A family's carbon footprint and power costs will both be reduced by a home-built electric vehicle. Electric cars have a huge amount of promise in the future. The charging station is the logical place for these cars to start. However, this is simply the first stage in a prospective trip that may involve charging cities, houses, banks, and other industrial sectors. Therefore, the potential for electric cars is enormous. Since the mid-1980s, research facilities like NASA have been developing the technology for electric cars. In a few years, current technology will undoubtedly be far more advanced. Some predict that soon we'll see self-sustaining electric cars that gather energy through their surroundings. These cars can even run on alternate energy sources like wind and will demand extremely minimal maintenance. Hence, the research paper briefs about the wide development of the electric vehicles.
Comparison of different vehicle power trains
Journal of Power Sources, 2001
Four different alternatives of mobile power train developments (hybrid diesel, fuel cell operating with hydrogen produced on a petrochemical basis, methanol reformer-fuel cell system, gasoline reformer-fuel cell system), are compared with the gasoline internal combustion engine (ICE), for well-to-wheel efficiencies, CO 2 emissions, and investment costs. Although the ICE requires the lowest investment cost, it is not competitive in well-to-wheel efficiencies and less favourable than the above alternatives for CO 2 emissions. The hybrid diesel power train has the highest well-to-wheel efficiency (30%), but its well-to-wheel carbon dioxide emission is similar to that of the fuel cell power train operated with compressed hydrogen produced on a centralised petrochemical basis. This latter case, however, has the advantage over the hybrid diesel power train that the carbon dioxide emission is concentrated and easier to control than the several point-like sources of emissions. Among the five cases studied only the on-board reforming of methanol offers the possibility of using a renewable energy source (biomass). #

IJERT-Comprehensive Analysis of Electric Vehicles
International Journal of Engineering Research and Technology (IJERT), 2020
https://www.ijert.org/comprehensive-analysis-of-electric-vehicles https://www.ijert.org/research/comprehensive-analysis-of-electric-vehicles-IJERTCONV8IS06012.pdf This paper proposes the recent development of electric vehicles across the global automobile industry. It provides an overview about the transportation infrastructure through the electricity. Electric vehicle drives offer a number of advantages over conventional internal combustion engines, especially in terms of lower local emissions, higher energy efficiency, and decreased dependency upon oil. EVs first came into existence in the mid-19th century, when electricity was among the preferred methods for motor vehicle propulsion. EVs saw a rising again due to technological developments, and an increased focus on renewable energy. This paper emphasizes the various components of electric drive and their choice of selection to make use.
Key Developments for Electric Vehicles in Local Transport
2019
Environment protection in Metro cities is a growing concern. Automobile sector play a very important role in the vision of green friendly environment. Continual reduction of reserve of fossil fuel and increased level of pollution has further forced to think of alternative is an electric vehicle. Mission 2030 for Government of India-"All vehicle will be Electric Vehicle" has given a boost to the E-vehicle and it will lead to generate cumulative savings of 846 million tons of CO2 over the total deployed vehicle's lifetime. Many corporates have already jumped to this sector as it is future of automobile sector. Now, electric vehicle is a reality and available for local public transportation. This paper covers an overview of the present status of electric vehicles in India with respect to technological growth. Key challenges faced by electric vehicle are also discussed.
In order to minimize oil dependency and the negative environmental impacts as described within the fifth assessment report of the Intergovernmental Panel on Climate Change (IPCC), emissions of greenhouse gases (GHG) from all sectors of the global economy have to be reduced. Road freight transport is one of the fastest growing modes of transport and has an increasing share in the total GHG emissions of transport. Current concentration is mainly on incremental technology developments to reduce fuel consumption of conventional vehicles. However, there may be potential for (near) zero tailpipe emission vehicles that could result in the large-scale GHG reduction that is needed. In order to identify early (niche) markets for electric vehicle application, this paper gives an overview of current demonstration project activities in terms of powertrain technology implemented and transport task of investigation, with special focus on vehicles with a gross vehicle weight not exceeding 3.5 tonne...
Making the Case for Electrified Transportation
IEEE Transactions on Transportation Electrification, 2015
In order to achieve lower fuel consumption and less greenhouse gas emissions, we need higher-efficiency vehicles with improved performance. Electrification is the most promising solution to enable a more sustainable and environmentally friendly transportation system. Electrified transportation vision includes utilizing more electrical energy to power traction and non-traction loads in the vehicle. In electrified powertrain applications, the efficiency of the electrical path and the power and energy density of the components play important roles to improve the electric range of the vehicle, to run the engine close to its peak efficiency point, and to maintain lower energy consumption with less emissions. In general, the electrified powertrain architecture, design and control of the powertrain components, and software development are coupled to facilitate an efficient, high-performance, and reliable powertrain. In this paper, enabling technologies and solutions for the electrified transportation are discussed in terms of power electronics, electric machines, electrified powertrain architectures, energy storage systems, and controls and software.
