AT 300K

AT 310K

AT 324K

RESULTS:For a 10 cell series lithium ion battery model we simulate the thermal effects and compare life cycle performance at temperatures;300K,310K & 324K, charge & discharge rates using MATLAB. results are as follows

1-4 cells are normal cell 5 th cell is faulty 6-10 cell is normal cell as we are simulating thermal effect on we give Cyclic Charge/ Discharge Profile to circuit the waveform you can see above results all conditions it is same but when circuit is running on this drive cycle profile as 5th cell was faulty it will show temperature rise high than any other cell and the life cycle of cell get reduced and cell even can get destroyed.

CASE 1 temp of results at 300 k the 1-4 and 6-10 cell temp is near to 316kbut 5th faulty cell temp goes to 330k and the drive cycle is shown which is Cyclic Charge/ Discharge drive cycle

CASE 2 we give temp 310 k and 1-4 and 6-10 cell temp is near to 326 k but 5th faulty cell temp goes to 340k ie 66.85°C and the drive cycle is shown which is Cyclic Charge/ Discharge drive cycle

CASE 3 we give temp 324 k ie 50.85°C and 1-4 and 6-10 cell temp is near to 340 k but 5th faulty cell temp goes to 354k and the drive cycle is shown which is Cyclic Charge/ Discharge drive cycle

CONCLUSION:

hence compared life cycle performance at 300k ,310k,324k& charge & discharge rates using MATLAB.
