Charge and Discharge Module Assembly with Coolant Control

Since R2024a

This example shows how to perform a charging and discharging cycle on a battery module assembly while monitoring the cell temperature and enabling cooling.

A Battery CC-CV block cyclically charges and discharges the battery module assembly. At the start of the simulation, each cell of the module assembly starts at a different temperature. During the cycle, a Battery Coolant Control block monitors the cell temperature and starts cooling the module assembly if the battery cells surpass a limit temperature value of 308.15 K. When the cell temperature goes below 298.15 K, the Battery Coolant Control block deactivates the coolant flow.

Model Overview

Open the coolantControl model.

modelname = "coolantControl";

The model comprises a pre-generated ModuleAssembly block, a Battery CC-CV block, and a Battery Coolant Control block. The ModuleAssembly block represents a battery module assembly with a battery module and a cooling plate at the bottom. The battery module comprises three parallel assemblies with a gap between each parallel assembly of 0.5 mm, a detailed model resolution, and an enabled ambient thermal path. Each parallel assembly comprises four single-stacked pouch cells. Each pouch cell measures 300 mm in length, 100 mm in height, and 10 mm in thickness. For more information on how to generate the Module block, open the CoolantControlCreatelib.mlx file.

Run the simulation.

ssc_coolantCntrl = sim(modelname);
