An intelligent battery management system for electric and hybrid electric vehicles

One of the keys to the acceptance of electric and hybrid electric vehicles is the increased longevity of the large battery packs used in the vehicles. The objective of this research is to develop an intelligent battery management system that will lengthen the lifetime of the battery pack. The key to this operation is monitoring and charging of individual batteries in a large battery array. This paper describes the design and development of this overall intelligent battery management system.
