A review on powertrain subsystems and charging technology in battery electric vehicles: Current and future trends

Abstract

The transport industry is a major contributor to both local pollution and greenhouse gas emissions (GHGs). The key challenge today is to mitigate the adverse impacts on the environment caused by road transportation. The volatile market prices and diminishing supplies of fuel have led to an unprecedented interest in battery electric vehicles (BEVs). In addition, improvements in motor efficiencies and significant advances in battery technology have made it easier for BEVs to compete with internal combustion engine (ICE) vehicles. This paper describes and assesses the latest technologies in different elements of the BEV: powertrain architectures, propulsion and regeneration systems, energy storage systems and charging techniques. The current and future trends of these technologies have been reviewed in detail. Finally, the key issue of electric vehicle component recycling (battery, motor and power electronics) has been discussed. Global emission regulations are pushing the industry towards zero or ultra-low emission vehicles. Thus, by 2025, most cars must have a considerable level of powertrain electrification. As the market share of electric vehicles increases, clear trends have emerged in the development of powertrain systems. However, some significant barriers must be overcome before appreciable market penetration can be achieved. The objective of the current study is to review and provide a complete picture of the current BEV technology and a framework to assist future research in the sector.

A Review on Vibrations in Electric and Hybrid Electric Vehicles

“…The passenger and goods mobility at the surface level are a very essential requirement and are presently taken care of mainly by automobiles powered by thermal prime movers such as petrol and diesel engines. However, in the 21st century, issues faced by automobiles such as depleting oil sources, increased exhaust pollutants, causing air pollution, difficulty in meeting the stringy emission norms laid down by the regulatory bodies, noisy operation, higher maintenance, and running costs have led to the development of alternative modes of transportation [1].…”
