A Review on Fast Charging Methodologies of Electric Vehicles

Abstract

The Li-Ion battery is charged using a constant voltage, constant current charging method. The solution, photovoltaic energy, is making its appearance in the EV charging infrastructure. By altering the transformer ratio, the inverter's voltage gain can be adjusted. Instantaneous thermal gradients are altered by fast charging. The grid and electricity quality may be impacted by EV charging.The goal of this study is to create a comprehensive, current overview of fast charging techniques for battery-electric vehicles (BEVs). The foundational ideas of single battery cell charging as well as existing and upcoming charging standards are covered in this paper. Globally, battery-powered electric vehicles are becoming more and more common. Numerous causes, such as the need to lessen noise and air pollution and our reliance on fossil fuels, are driving this trend. The primary disadvantage of modern electric vehicles is their short range and the length of time needed to charge their batteries. Through research and development, great strides have been achieved recently to use pulse charging, as opposed to continuous current and/or voltage delivery, to shorten the charging period of the batteries in electric vehicles. The portion that needs to be concentrated on estimating the electrical properties of the vehicle's battery is crucial for learning about the potential driving range.
