Catl 280Ah 3.2V The highest quality supplier in China
Internal resistance: about 0.2 milliohms
Size: 72-173-205mm
Single weight: 5.3Kg
The main parameters of Ningde 280 A-hour battery cells are as follows
1. Voltage: nominal voltage 3.2V, charging cut-off voltage 3.65V, discharge cut-off voltage 2.5V.
2. Capacity: The nominal capacity is 280Ah. Generally speaking, the actual capacity will be slightly higher than this value. This is to ensure that the output of the nominal capacity can be met under various working conditions.
3. Internal resistance: ≤0.18mΩ, lower internal resistance can reduce the energy loss of the battery during charging and discharging, and improve the efficiency and performance of the battery.
4. Charging and discharge current: the continuous charging current is 1C, and the maximum charging current of charging (CC-CV) is 3C; the continuous discharge current is 1C, and the maximum discharge current is 3C. The ”C“ here is the unit of the battery charging and discharge magnification. 1C means charging and discharging according to the nominal capacity of the battery. For example, for a 280Ah cell, the charging current of 1C is 280A, and the charging current of 3C is 840A (280A×3).
Five. Working temperature:
• The charging temperature range is 0°C~65°C;
• The discharge temperature range is -35°C~65°C;
6. Weight: about 5.34kg.
7. Size: The common size is 72173207 mm.
8. Recommended SOC use window: SOC (State of Charge) is 10%~90%. Using the battery within this range can give full play to the performance of the battery and help extend the service life of the battery.
