OCV Fitting
Application ID: 149681
This application performs parameter estimation (fitting) of the active lithiation windows of the negative and positive electrode materials of a lithium-ion battery, based on a experimental open-circuit voltage (OCV) curve measured as a function of the cell state of charge (SOC).
Once a good fit has been obtained, the app can be used to generate parameter text files, which may be imported into any Parameters node in a model .mph file, where they can be used as a basis for defining a more complex battery model using the Lithium-Ion Battery interface, or a Two Electrodes model in the Lumped Battery or Battery Pack interfaces.
This application 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 Specification Chart 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.
