Flow chart of simulation process of a battery pack using COMSOL with MATLAB®.

This work is to present an implementation of COMSOL with MATLAB® [1] for the liquid cooling system of a battery pack based on the physics in COMSOL. The m.file of a model of battery module from COMSOL 4.2 is exported and modified to run in MATLAB®, as well as is managed by using another m.file. The advantage of running the model of COMSOL in MATLAB® is that each part in system built in COMSOL 4.2 or MATLAB® can be combined together and simulated at the same time in MATLAB®. Moreover, the results are also easy to monitor and collect in MATLAB thanks to MATLAB®’s functionality.
