Project 1

1. Voltage- 120V

Power- 150Kw

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. BMS Topology

Since the voltage of the battery pack is 120 and the number of cells in series is 34

Master and Slave topology is used for this battery pack
