20S3P Battery Configuration
The battery pack consists of:
20 Series × 3 Parallel = 60 Cells
Each parallel group:
3 × 4500mAh = 13500mAh (13.5Ah)
Nominal Voltage
20 × 3.6V = 72V
Maximum Charging Voltage
20 × 4.2V = 84V
Nominal Energy
72V × 13.5Ah = 972Wh
Therefore, the battery provides approximately 972Wh (0.972kWh) of nominal energy.
3C Lithium-Ion Configuration
The 3C specification refers to the discharge capability of the selected DMEGC cells. The 3P 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, interconnect design, 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, with a charger output of 84V.
