20S13P Battery Configuration
The battery pack consists of 20 series groups, with 13 cells connected in parallel in each group.
20S × 13P = 260 cells
Using 3.7V 4500mAh cells:
- Total cells: 20 × 13 = 260 cells
- Nominal voltage: 20 × 3.6V = 72V
- Maximum charging voltage: 20 × 4.2V = 84V
- Parallel capacity: 13 × 4.5Ah = 58.5Ah
- Nominal energy: 72V × 58.5Ah = 4,212Wh
- Total energy: Approximately 4.21kWh
3C Lithium-Ion Configuration
The cells are specified as 3C-rated cells. The complete battery pack’s safe operating current is determined by the BMS and overall electrical and thermal design, rather than the cell C-rating alone.
The final discharge capability depends on:
- BMS continuous and peak current rating
- Cell specifications
- Nickel/copper interconnection design
- Wire gauge
- Connector rating
- Thermal management
- Operating temperature
BMS Protection
A suitable 20S NMC BMS can provide:
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Over-temperature protection
- Cell voltage monitoring
- Cell balancing
- Charging and discharging control
A Smart BMS can also be configured with Bluetooth, CAN, UART or RS485 communication depending on the application.
