20S5P Battery Configuration
The battery pack consists of:
20 Series × 5 Parallel = 100 Cells
Each parallel group:
5 × 4500mAh = 22500mAh (22.5Ah)
Nominal Voltage
20 × 3.6V = 72V
Maximum Charging Voltage
20 × 4.2V = 84V
Nominal Energy
72V × 22.5Ah = 1,620Wh
Therefore, the battery provides approximately 1.62kWh of nominal energy.
3C Lithium-Ion Configuration
The 3C specification refers to the discharge capability of the selected DMEGC cells. The 5P configuration provides increased current capability compared with a single cell.
The actual continuous and peak current rating of the finished battery should be determined according to the cell specifications, BMS rating, nickel/busbar construction, wiring, connectors, thermal management, and vehicle/controller requirements.
BMS Protection
A suitable 20S NMC BMS can provide:
- Overcharge Protection
- Over-Discharge Protection
- Over-Current Protection
- Short-Circuit Protection
- Cell Voltage Monitoring
- Cell Balancing
- Temperature Monitoring
- Charging & Discharging Protection
For this 72V-class battery, the BMS and charger should be specifically selected for a 20S NMC configuration. The appropriate maximum charger output is 84V.
