Parameter Estimation of a Time-Dependent Equivalent Circuit Battery Model
Application ID: 103671
This tutorial uses an equivalent circuit approach for modeling the performance of a lithium-ion battery, requiring no knowledge about the internal chemistry or structure of the battery. A 0D equivalent circuit battery model is defined based on a resistor connected in series with a resistor-capacitor couple.
An optimization solver is used for parameter estimation using experimental load cycle and open circuit voltage data. The equivalent circuit model with the optimized parameter values are subsequently used for predicting the battery performance for an arbitrary load cycle.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Tabella delle Funzionalità and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
