6S9P Battery Configuration
The battery pack contains 54 DMEGC cells arranged in a 6S9P configuration:
- 6 cells/groups in series = 6S
- 9 cells in parallel per group = 9P
- Total cells = 6 × 9 = 54 cells
- Capacity = 9 × 4.5Ah = 40.5Ah
- Nominal voltage = 6 × 3.7V = 22.2V
- Maximum charge voltage = 6 × 4.2V = 25.2V
- Nominal energy = 22.2V × 40.5Ah = 899.1Wh
3C Lithium-Ion Configuration
The theoretical 3C current calculation is:
40.5Ah × 3C = 121.5A
The 121.5A value is a theoretical cell-based calculation and should not automatically be considered the continuous discharge rating of the finished battery pack. The actual current capability must be determined by the selected BMS and complete battery construction.
BMS Protection
A suitable 6S NMC Lithium-Ion BMS can provide:
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Over-temperature protection
- Cell balancing
- Charging and discharging protection
The BMS current rating should be selected according to the application’s continuous and peak current requirements.
