6S7P Battery Configuration
The battery pack contains 42 DMEGC cells arranged in a 6S7P configuration:
- 6 cells/groups connected in series = 6S
- 7 cells connected in parallel per group = 7P
- Total cells = 6 × 7 = 42 cells
- Capacity = 7 × 4.5Ah = 31.5Ah
- Nominal voltage = 6 × 3.7V = 22.2V
- Maximum charge voltage = 6 × 4.2V = 25.2V
- Nominal energy = 22.2V × 31.5Ah = 699.3Wh
3C Lithium-Ion Configuration
The theoretical 3C current calculation is:
31.5Ah × 3C = 94.5A
The 94.5A figure is a theoretical cell-based calculation and should not automatically be considered the finished pack’s continuous discharge rating. The actual safe current depends on the BMS and complete battery-pack design.
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 should be selected according to the required continuous and peak current of the application.
