Lithium-Ion Battery Base Model in 1D

Application ID: 18437

This application example is useful for investigation of the following:

polarization (voltage drop),
internal resistance,
state-of-charge (SOC), and
rate capability,
in lithium-ion batteries under isothermal conditions.

Some of the listed properties play an important role in battery management systems (BMS) in, for instance, electric and hybrid electric vehicles (see figure). The more properties that can be monitored accurately, the easier it is to manage the battery in a manner maximizing energy output and lifetime, and guaranteeing safety.

For battery manufacturers, the same properties can be looked upon when optimizing the design of the battery, for example choice of materials and thickness of electrodes.

This model setup is done in the Lithium-Ion Battery interface with Initial Cell Charge Distribution feature and incorporates mainly default physical properties. The material properties are taken from the Batteries & Fuel Cells Material Library.

For running the model you only need to decide upon which initial cell voltage (or initial cell SOC), battery capacity, and thicknesses of electrodes and separator you want.

This model example illustrates applications of this type that would nominally be built using the following products:
