| Abstract |
In this paper, a real time estimate of a battery
model is proposed. The existing impedance model is
accurate in predicting the behavior of a battery. However, it
is complex and not applicable for real time applications.
Also, it requires much time and cost to obtain the
parameters of the model. A simple lumped circuit model is
presented. The parameters and states (overvoltages) of the
battery are estimated with a filtering technique and system
identification theory. It is verified through simulations and
experiments that the proposed method is in good agreement
with the dynamic characteristics of the battery, regardless
of the conditions of the battery, and the estimated
overvoltages are given physical meanings through a
comparison with an impedance model with complex RC
ladder circuits. |
