Project 2 Thermal modeling of battery pack

RESULT EXPLANATION

• For a 10-cell series lithium-ion battery model, we simulate the thermal effects and compare life cycle performance at various temperatures, charge & discharge rates using MATLAB. results are as follows:
• 1-4 cells are normal cell 5 the cell is faulty 6-10 cell is normal cell as we are simulating the thermal effect we give Cyclic Charge/ Discharge Profile to circuit the waveform you can see the above results all conditions is the same but when ckt is run on this drive cycle profile as 5th cell was faulty it will show a temperature rise high than any other cell the life cycle of the cell get reduced and cell even can get damaged
• so as we give temp of results at 300 k ie 26.85°C the 1-4 and 6-10 cell items near 316k
• but the 5th faulty cell temp goes to 330k ie 56.85°C and the drive cycle is shown which is Cyclic Charge/ Discharge drive cycle
• in condition two we give temp 310 k ie 36.85°C and 1-4 and 6-10 cell temp is near 326 k but the 5th faulty cell temp goes to 340k ie 66.85°C and the drive cycle is shown which is Cyclic Charge/ Discharge drive cycle
• in condition two we give temp 324 k ie 50.85°C and 1-4 and 6-10 cell temp is near 340 k but the 5th faulty cell temp goes to 354k ie 80.85°C and the drive cycle is shown which is Cyclic Charge/ Discharge drive cycle

conclusion

• We simulated the thermal effect and compared it at various temperatures, faulty cell temp rises more than the normal cell charge and the discharge cycle is given and due to temp rise it can damage the cell and reduce the performance of the battery.
