Project 1

Design a battery pack for a car roughly 150 Kw with 120 V. Use 3500 mAh 3.6V nominal NMC chemistry cell.

1) Design the battery pack configuration.

Answer:-

2)Draw the BMS topology for this battery pack.

Answer:-

Conclusion:- Here we have calculated the total number of cells in series and parallel for the given ratings. Also the more suitable topology has been suggested for the given ratings.

We can see the number of cells in series are less and number of cells in parallel are more. This is because the current of the system is high. Hence when the current is too large the number of cells in parallel will be more and when voltage of the sytem is too large then the c=number of cells in series will be high.
