Battery Modeling

Lithium ion battery characterization, state estimation, cell balancing, and thermal management

This file contains Simscape Electrical Lithium-ion battery models for parameter estimation and simulation.

1. Unzip the project.

2. Double-click BatteryModeling.prj to set up the MATLAB path. The html index contains links to open each example.

Demos:

1. 3S-1P battery pack CCCV charge with passive balancing using Simscape Electrical. Charge / discharge cycling with passive balancing, including thermal effects.

2. EV battery cooling. Liquid cooling of an automotive battery pack.

3. Cell characterization. Parameter estimation of single cell using pulsed discharge experiments.

4. SOC Estimation using UKF.

5. SOH (internal resistance) online estimation using EKF. Internal resistance grows over time and the nonlinear Kalman Filter estimates its evolution.

6. Battery App. This app can be used to find battery parameters from datasheet information.
