Yes, it is possible to simulate the thermal behavior of the battery pack using Simulink and Simscape. Here are the steps you can follow:
- Create a thermal model of the battery pack: You can create a thermal model of the battery pack using Simscape Thermal Liquid library. You will need to create a thermal network with a heat source (heating coils) and a heat sink (surrounding environment and insulation). You can use thermal resistors, capacitors, and thermal transmitters to build the thermal network.
- Model the battery behavior: In addition to the thermal model, you can also use Simulink to model the electrical behavior of the battery pack. You can use a battery block from Simscape Electrical library or a custom block that models the battery's electrical behavior, including its voltage, current, and state of charge.
- Connect the thermal and electrical models: You can connect the thermal and electrical models using Simscape SimElectronics library. This will allow you to simulate the battery's thermal behavior under different electrical loads, charging/discharging conditions, and environmental temperatures.
- Run the simulation: Once you have created the thermal and electrical models and connected them, you can run a simulation in Simulink to determine the heating power required to keep the battery above 5°C in a -40°C environment. You can use Simulink's simulation tools to analyze the simulation results and optimize the heating power input as needed.
