Project 1
Design a battery pack for a car roughly 150 Kw with 120 V. Use 3500 mAh 3.6V nominal NMC chemistry cell.
- Design the battery pack configuration.
- Draw the BMS topology for this battery pack.
Power- 150Kw
Voltage- 120V
Current= Power/Voltage
= 150000/120
=1250 Amps
NMC Cell values
Voltage- 3.6V
Current- 3500 mAh
Current- 3.5Ah
To design battery pack configuration we have to consider voltage for number of cells in series
Number of cells in series= 120/3.6=34 cells
To attain current we have to arrange cells in parallel
Number of cells in parallel=1250/3.5=358
Therefore to design a battery pack of 120V and 1250 Amps we need 34 Cells in series and 358 cells in parallel
that is 34S358P combination
2.Draw the BMS topology for this battery pack. BMS topology of 34 cells
