Project 2 Thermal modeling of battery pack

For a 10 cell series lithium ion battery model, simulate the thermal effects and compare life cycle performance at various temperatures, charge & discharge rates using MATLAB.

Ans-

Putting the constat parameter of PS contant to 3

Battery parameters can be changed from the below figures.

The SOC and temperature sensor output are connected to the scope.

Below is the simulink model according to the question.

In the below simulink model first we choose a Battery(table based) block and then right clicking at and choosing the correct options for the model and now connecting its one end to scoe with the help of PS-simulink converter and connectin its another end to convectve heat transfer. After that connecting convective heat transfer to to controlled temperature sensor and proving it a temperature source of 400k .Now connecting PS cnstant to current controlled source and further connecting it to resistor of 10 ohm and conneting th ebatter(table based) to controlled current source. Here the 10 Battery(table based)are used.

The above is the simulink model for a 10 cell series lithium ion battery model, simulate the thermal effects

The below is the curve for SOC and temperature at 400k

From the below curve we can see that as the temperature increases the SOC decreases therefore as the temperature increases the discharge rate increases so the battery must be operated at low temperature.

The below is the curve for SOC and temperature at 300k

From the below curve we can see that as the temperature increases the SOC decreases therefore as the temperature increases the discharge rate increases so the battery must be operated at low temperature.
