Analysis of performance improvement in energy storage system for electric vehicles: a review

The selection of energy storage system is very crucial for electric vehicles. It should have good energy density, considerable power density and also it must be light weight. So a battery with considerably high energy density must be used in electric vehicles. Lithium ion batteries are very much preferred as electric vehicle batteries. They have high energy density, high life cycle and smooth operation. But the problem related with lithium batteries is they have high temperature sensitivity, and their operation will be affected by over current charging and over current discharging beyond their maximum rated values and also influenced by driving conditions and performance of motors used. So battery management, control and optimisation system is essential in electric vehicle energy storage battery packs. This paper is a review of the design of a novel battery management and control system for lithium ion batteries for performance improvement in electric vehicles.
