Enhanced model for Lithium-Polymer cells including temperature effects

Abstract

An accurate model of the elementary accumulation device is fundamental for sizing and controlling the battery pack to be used in electric and hybrid vehicles. Indeed, the implementation of such a model within the Battery Management System makes it possible to evaluate the status and the behavior of the battery pack in every condition and to apply a correct control strategy. This work shows the characterization and modeling of a commercial Lithium-Polymer cell, which properly considers thermal effects on cell behavior. The specific designed thermostatic chamber is described and the experimental results are presented and compared to those simulated with the developed model.
