Abstract

A reliable and accurate estimation of the parameters of batteries equivalent models is of paramount importance in many applications. This paper is focused on electric vehicle framework. A simplified method for estimating these parameters is presented and validated. The proposed methodology introduces the concept of apparent state of discharge (ASOD), i.e., the traditional state of discharge adjusted in order to take into account the effects of current and temperature. This ASOD is, then, used to estimate the open circuit voltage and, consequently, the output voltage of the battery cells. The effectiveness of this method has been experimentally tested on a real Lithium-ion cell in order to estimate the expected range of an electric vehicle.
