No. Item Parameters Test Method and Condition
1 Capacity ≥26.0Ah The cell performs standard charge and discharge,calculate the discharge capacity.
2 AC impedance 0.8 ± 0.15 mΩ AC impedance of the cell is measured at 1KHz at 30%SOC.
3 Rate Discharge 1.0C ≥ 100%
2.0C ≥ 99%
3.0C ≥ 95%
After standard charging,discharge capacity is measured with the various currents at the cut off voltage of 2.7V
4 Discharge at high & low temperature 45,55℃≥95%;
25℃≥100%;
10℃≥95%;
0℃≥90%;
-10℃≥85%;
-20℃≥80%;
-30℃≥70%
After standard charging,the cell is stored in different temperature (25℃,-20℃,0℃,10℃, 45℃,55℃) for 2 hours, then test the cell
capacity separately in each temperature with standard discharge method. (-10, 0℃ cut off at 2.5V, -20,-30℃ cut off at 2.2V).
5 Cycle Life 25℃,
Remaining capacity≥80%
The cell performs charge and discharge cycle at 1C current for 3000 times, and between charge and discharge the cell should rest at least 10 min,then test the remaining capacity.
6 Storage at 25℃
100%SOC
Capacity recovery
≥98%
After standard charging,the cell stored at 25℃ for 30 days, then measured the remaining and recovery capacity by standard discharge method.
7 50%SOC
Storage at 45℃
Remaining
capacity≥95%;
Capacity recovery
≥98%
After standard charging to 50%SOC, the cell stored at 45 ℃ for 30 days, then the cell stored at 25℃for 4h, measured the remaining capacity and capacity recovery by standard discharge
method.
