Test Standard
检测标准 |
| 1 | Normal temperature discharge performance | Standard charge, then rest for 10min and discharge at 0.5C5A、1C5A 、3C5A ,
5C5A to 2.0V respectively. |
Discharge capacity/Nominal capacity×100%.
0.5C5A≥100% 1C5A≥95% 3C5A≥90% 3C5A≥90% |
| 2 | Normal temperature ratio charging performance. | At normal temperature environment, let stand for 1h after the discharge standard with 2C constant current charging to 3.65V, let stand for 1h, 1C discharge to 2.0V | Discharge capacity/Nominal capacity×100%≥80% |
| 3 | Normal Temperature Storage | Store for 28days after standard charge,then discharge at 0.2C5A to 2.0V measuring residual capacity; Then standard charge/discharge cycle for 3times to obtain the recoverable capacity. | Residual capacity≥Nominal capacity×85%
Recoverable capacity≥Nominal capacity×92% |
| 4 | Cycle Life | After 2000 cycles at standard charge and discharge, the residual discharge capacity is above 80% of initial capacity. | ≥2000 cycles |
| 5 | Storage Characteristics | Stored for 12 months in room-temperature
at 50%SOC.After storage cell shall be conducted standard charge/discharge cycle for 5 times to obtain the recoverable capacity. |
Recoverable capacity≥Nominal capacity×90% |
| 6 | Power performance | Battery 1C constant current constant voltage charge cut-off current 0.05C to 3.65V C, put aside 30 min, exiled to 1C constant electric 30 min, adjust the sample SOC to 50%; Aside 30 min, with maximum discharge current discharge 5s,put 1min, then 1C discharge to 2.0V,collect data, computing power | |
| 7 | Discharge temperature Characteristics | Standard charged in normal temperature,stored under the following temperature for 3h, then discharged at constant current of 0.2 C5A to 2.0V. | Discharge capacity/Nominal capacity×100%
-20℃ ≥40% 0℃≥65% 10℃≥80% 25℃≥100% 60℃≥95% |
