A comprehensive study of key Electric Vehicle (EV) components, technologies, challenges, impacts, and future direction of development

Abstract: Electric vehicles (EV), including Battery Electric Vehicle (BEV), Hybrid Electric Vehicle (HEV), Plug-in Hybrid Electric Vehicle (PHEV), Fuel Cell Electric Vehicle (FCEV), are becoming more commonplace in the transportation sector in recent times. As the present trend suggests, this mode of transport is likely to replace internal combustion engine (ICE) vehicles in the near future. Each of the main EV components has a number of technologies that are currently in use or can become prominent in the future. EVs can cause significant impacts on the environment, power system, and other related sectors. The present power system could face huge instabilities with enough EV penetration, but with proper management and coordination, EVs can be turned into a major contributor to the successful implementation of the smart grid concept. There are possibilities of immense environmental benefits as well, as the EVs can extensively reduce the greenhouse gas emissions produced by the transportation sector. However, there are some major obstacles for EVs to overcome before totally replacing ICE vehicles. This paper is focused on reviewing all the useful data available on EV configurations, battery energy sources, electrical machines, charging techniques, optimization techniques, impacts, trends, and possible directions of future developments. Its objective is to provide an overall picture of the current EV technology and ways of future development to assist in future researches in this sector

Utility Grid: Present Challenges and Their Potential Solutions

Utility electric grid is expected to face some of the major challenges modern power generation, and distribution systems will pose in the years to come. In this paper, a complete overview of those challenges is presented, for the first time, with proper detailed explanation and their implication. Smart grid security, power system generation and distribution side complications, integration of renewable energy systems, storage devices, modern equipment, and technologies make modern-day power generation and transmission more complex than ever. Thus, the utility grid requires major renovations and upgraded protection schemes to adapt to these changes. The required solutions with discussions are also presented in this paper. In addition, the challenges are classified according to their severity, and the solutions that are best suited to mitigate each challenge are also identified. Challenges of the modern utility grid and their prospective solutions are expected to open up a lot of opportunities for researchers around the world, who work toward improving the utility by adopting latest technologies

Off-Road Construction and Agricultural Equipment Electrification: Review, Challenges, and Opportunities

Though the current wave of electric vehicles is transforming the on-road passenger and commercial vehicle fleets, similar attempts in the off-road equipment sector appear to be lacking. Because of the diverse equipment categories and varied applications, electrifying off-road equipment requires significant research and development. A successful electrification of such equipment can offer an array of benefits, including reduced air and noise pollution, higher energy efficiency, and increased productivity. This paper provides a review of the current state of technology in off-road equipment electrification, with a focus on the equipment used in construction and agricultural applications. The paper also discusses advantages of, and challenges associated with, electrifying off-road construction and agricultural equipment. In addition, potential solutions for overcoming these challenges as well as opportunities to facilitate the electrification of off-road construction and agricultural equipment are identified
