Battery Management System for Electric Vehicle

Abstract

The healthy system in any country is a sign of healthy lifestyle. The rapid depletion of fossil fuels and harmful effects on the environment are forcing the use of electric vehicles on a large scale. Now days the proper use of energy sources that can available in nature is very important and efficiency point of view electric vehicles are the very good choice. The battery is a basic component of electric vehicles that signals a step forward in the direction of stable mobility. Lithium chemistry is now known as the energy storage in electric vehicles. However, many research points are still open including the optimal selection of cell material and the development of electronic circuits and algorithms for more efficient use of batteries. This paper reviews battery performance and discusses the requirements and standards applicable to the battery management system(BMS). The architecture for implementation battery management and techniques for state of charge and cell balancing are reported.
