Battery and battery management for hybrid electric vehicles: a review

According to the legal, social and economic requirements for improved road transportation hybrid electric vehicles (HEVs) are one of the most intensively investigated vehicle concepts of today. To exploit their potential for emission reduction and performance improvement the energy storage system has to be considered as one of the key components of HEVs. This paper reviews the present state of the art pointing out advantages and drawbacks for each battery technology relevant for HEV application. Moreover, it describes the main constrains and requirements from the battery management's point of view. The tools usually applied by battery system developers are covered as well as the processes for identification and design of the optimal battery pack and the appropriate battery management. Finally, the main adjustments that are necessary for customizing a basic battery management system for a given battery chemistry are discussed.Battery and battery management for hybrid electric vehicles: a review
