This is a Python version of Gregory Plett's enhanced self-correcting (ESC) battery cell model. The original code is written in Matlab which is available in the ESCtoolbox at mocha-java.uccs.edu/BMS1/.
The open-circuit voltage (OCV) files are located in the ocv_model/ folder
where the OCV model is the ocv.py file. The results and plots generated from
this model should be similar to the Matlab runProcessOCV.m plots. The
funcs.py file contains the OCVfromSOCtemp function while the models.py
file contains model objects used by the OCV model. The data.py file plots the
experimental data from the csv files located in the ocv_data/.
Battery test data for the A123 cell is available in the ocv_data/ folder as
csv files. The data files were exported from the Excel spreadsheets in the
OCV_Files/A123_OCV directory of the Matlab ESCtoolbox. Plots of the battery
test data are generated with the data.py script. Change the tc variable to
view plots from the other temperature tests. For example, change the tc
string to N05 to create plots for the CSV files named A123_OCV_N05_S1,
A123_OCV_N05_S2, A123_OCV_N05_S3, and A123_OCV_N05_S4. The figures produced
from the script should be similar to the graphs shown in the A123_OCV_N05_S1,
A123_OCV_N05_S2, A123_OCV_N05_S3, and A123_OCV_N05_S4 Excel spreadsheets.
See the comments in each file for more information.
The dynamic model files are located in the dyn_model/ folder where the
dyn_model.py is the main file to run. The data from the dynamic battery tests
are located in the dyn_data/ folder.
See the comments in each file for more information.
Requires Python 3.6, Matplotlib, NumPy, and Pandas. The preferred method to install Python 3 and associated packages is with the Anaconda or Miniconda distribtion available at continuum.io/downloads.
Clone or download the files to your local machine. Start iPython from within
the ocv_model/ directory then type run ocv.py to run the OCV model.
