Sizing and performance analysis of battery pack in electric vehicles

Abstract

In this paper a battery-powered electric vehicle (BEV) model is presented along with a simple simulation-based iterative method of battery sizing. For simulations and sizing purposes the urban speed profile FTP-75 has been used. The model allows obtaining both voltage and current behaviour in the battery, which is useful for sizing and selection of several components of the electric vehicle. Finally a simple algorithm is proposed as a systematic iterative sizing method. This work is the result of the first stage in the creation of a complete object oriented EV model aiming at developing an integrated sizing and power-management procedure.
