0S9P Battery Configuration
The pack consists of:
10 Series × 9 Parallel = 90 Cells
Each parallel group:
9 × 5000mAh = 45000mAh (45Ah)
Voltage
10 × 3.6V = 36V nominal
Maximum Charging Voltage
10 × 4.2V = 42V
Nominal Energy
36V × 45Ah = 1,620Wh
So, the battery provides approximately 1.62kWh of nominal energy.
3C Lithium-Ion Cell Configuration
The 3C rating indicates the discharge capability of the selected cells. With 9 cells in parallel, the parallel arrangement can provide substantially higher current capability than a single cell.
However, the complete battery pack’s actual current rating should be determined by the BMS, cell specification, nickel/busbar design, wiring, connectors, thermal management, and controller requirements.
BMS Protection
A suitable 10S NMC BMS can be installed with this battery pack to provide:
- Overcharge Protection
- Over-Discharge Protection
- Over-Current Protection
- Short-Circuit Protection
- Cell Voltage Monitoring
- Cell Balancing
- Temperature Monitoring*
- Charging & Discharging Protection
*Temperature protection depends on the selected BMS.
The BMS current rating should be selected according to the application’s continuous and peak current requirements.
