Understanding Electric Vehicles Battery, Charging & It's Impact on Power Quality.

Battery is a device that converts chemical energy into electrical energy and vice versa. The use of battery in automobiles started in early 1900's. In initial stages, battery was used for energizing automobile accessories like head lamps, indicators, horn etc. The recent advances has put battery for use in staring IC engine with electric start, integrating music system in automobiles, mobile charging and even in some of the high end vehicles custom inverters are build on battery that makes the vehicle suitable for camping purpose. Now a day's the battery operated electric vehicles are becoming popular which addresses the key challenges in reducing pollution. Likewise the use of battery in automobile sector has advanced through the years. The cycling of battery is done in terms of charging and discharging. Depending upon the size and specifications, the time taken to charge battery differs. This charging time layoff hampers the performance of electric vehicles. Various strategies, battery charging methods, charging stations are proposed and developed by researchers leaving behind critical issues related to the power quality to be addressed. This paper focuses on advancements in battery usages and charging in Electrical Vehicles. The power quality issues arising as a result of non linear load are presented. [ABSTRACT FROM AUTHOR]
