The Economic Survey predicts that India's domestic electric vehicle market will see a 49 percent compound annual growth rate (CAGR) between 2022 and 2030, with 10 million annual sales by 2030.As the EV vehicles require Batteries this batteries charging power drawn by electric grid by using power converters. As there are fast chargers which consume less time for charging the battery, this type of chargers suddenly increases load, Harmonics and imbalance in power system and cause low PF in power system. Power quality issues arise such as harmonics distortion and their effects in charging the electric vehicle. In India day by day there are increases in Electrical vehicles. In EV charging mainly requires Battery charging which requires AC to DC converter due to that there is issue of Power quality as the number of chargers increased there is continues decrease in the THD of the combined currents. There are many bad effects of Power quality problems that can contribute to more energy costs, less production and faults in your electrical power system. Proactively addressing power quality issues from design stage can offer significant reliability and cost benefits. The presence of harmonics in the system may not always create an issue in a short run, however long term consequences should be considered the main issues are Deterioration of equipment leading to reduced lifespan ,Increased losses , Overheating, Reduced reliability leading to increased process interruptions ,Failures of drives, PLC’s or Power Supplies & Communication interference.
